  With the popularity of mobile phones and electric cars, lithium batteries are playing an increasingly important role in people’s lives. However, the fire and explosion accidents of electric vehicles and energy storage power stations caused by the inherent thermal runaway of lithium batteries also make the safety of lithium batteries a problem that cannot be ignored. This is also a long-term technical challenge faced by the lithium battery industry.

  At the Sichuan Science and Technology Awards Conference held recently, the team of Professor Xiang Yong from the University of Electronic Science and Technology of China, as the first completion unit, won the first prize of Sichuan Science and Technology Progress Award for the project "Key Technologies and Applications of Safety Control of Lithium Batteries Based on Multi-field Perception and Independent Flame Retardation". "How to improve the safety of lithium batteries and reduce the risk of overheating and explosion of batteries is a must." Xiang Yong said that in order to overcome this hurdle, he and his team have been exploring and struggling for more than ten years.

  Overcoming three major problems of lithium battery safety

  "Since 2012, we have gradually developed a complete electrochemical Qualcomm characterization platform and made a series of achievements in the research of lithium battery electrolytes, electrode materials and packaging materials." Xiang Yong said that he and his team began to try to apply the electrochemical Qualcomm characterization technology to the research on the dynamic change of the safety performance of lithium batteries in the whole life cycle, but during the research and development process, they found that the parameters monitored by the existing characterization methods were not enough to directly reflect the thermal runaway risk of lithium batteries.

  In Xiang Yong’s view, the thermal runaway process of lithium batteries involves manufacturing defects, aging and deterioration, management failure, abnormal environmental conditions and other factors, as well as manufacturing, storage and transportation, service and other links, and many technical problems need to be solved urgently.

  "There are three main problems to be overcome to solve the safety management and control of lithium batteries throughout their life cycle." Xiang Yong told Science and Technology Daily that real-time monitoring of thermal runaway of lithium battery is the first difficult problem. The difficulty lies in that conventional sensors cannot be embedded in the battery, and external signal sensing can only be relied on to infer the safety state of the battery, which will lead to inaccurate monitoring data.

  "Early warning and protection of lithium battery thermal runaway process is the second problem." Xiang Yong said that the measures taken after the thermal runaway of lithium batteries are usually "one size fits all", that is, shutting down the whole power supply system, which can not fundamentally eliminate safety accidents and will damage the service reliability of the power supply system.

  "The combustion blocking after the lithium battery caught fire is the third problem." Xiang Yong said that in the electrolyte of lithium battery, the organic solvent will produce flammable and explosive components when it is decomposed by heat, which will become the root cause of the fire and explosion of lithium battery after being mixed with oxygen. Therefore, once the lithium battery catches fire, it is extremely difficult to block the combustion.

  After clarifying the R&D problems and selecting the R&D direction, Xiang Yong team, together with Sichuan Institute of Safety Science and Technology, Sichuan Institute of Product Quality Supervision, Inspection and Testing, Sichuan Branch of China Tower Co., Ltd., Southwest Petroleum University and other Industry-University-Research companies, conducted in-depth research and exploration on the monitoring and control of the safety status of lithium batteries throughout their life cycle. Under the leadership of Xiang Yong, the participating research institutes have made concerted efforts to tackle key problems, giving full play to their respective strengths in the fields of theoretical research, technology development and application promotion.

  "We have successfully developed the in-situ preparation integration technology of multi-parameter thin film sensor and lithium battery current collector, realized the integrated integration, and solved the problem of sensor ‘ Buried, measured accurately, transmitted, with little influence ’ Key technical challenges. " Xiang Yong said that the team independently developed a special algorithm for artificial intelligence electrochemical countermeasure migration learning, and combined with the precise design model developed in the early stage, the accuracy of fault battery identification was improved to 98.6% in one fell swoop; Self-developed Qualcomm electrolyte preparation and screening technology and related devices improve the screening efficiency by 100 times, and realize the rapid optimization of the flame retardant and electrochemical properties of electrolyte.

  On April 24th, 2022, an expert group headed by Academician Wu Feng, a famous lithium battery expert, evaluated the technical achievements of lithium battery safety series developed by Xiang Yong team. The expert group agreed: "This achievement belongs to the international frontier technology field, and its indicators, model prediction accuracy and electrolyte self-extinguishing time are at the international leading level."

  Accumulated economic benefits exceeded 1 billion yuan.

  Since 2019, China Tower Energy Company has applied the project results to the power supply system of China Tower communication base station, supported the real-time online monitoring of more than 500,000 lithium batteries in the standby system of Sichuan communication base station, and warned the safety risks of lithium batteries for more than 20,000 times, with a success rate of 100%. More than 13,000 failed batteries were safely returned, and fire hazards were eliminated for more than 1,500 times, which effectively ensured the safe operation of the tower communication base station without any lithium battery thermal runaway accident.

  Shanghai Institute of Space Power Supply applied this achievement to solve the problem of sudden safety failure of lithium battery module. At present, this technology has been applied to Fengyun-4 02 satellite, new technology test satellite and other models; Sichuan Changhong Power Supply Co., Ltd. has developed a special integrated power supply with high weight ratio and high density of batteries and accessories based on the results of this project.

  In October 2019, after introducing the technical achievements of the project, Hubei Yiwei Power Co., Ltd. further developed the online capacity prediction technology of lithium batteries, and successfully applied the new technology to the transformation of existing production lines and the construction of new production lines, effectively improving the production capacity of lithium batteries.

  Xiang Yong told reporters that the popularization and application of the project results can help to develop high-safety and high-reliability new lithium battery products, eliminate hidden dangers of production safety risks, and also help to develop new lithium battery safety management system and improve the safety management and control level of lithium battery system. "Especially for lithium battery users, it can reduce the accident rate of lithium battery thermal runaway, reduce disaster losses and save operation and maintenance costs."

  The data shows that since March 2019, the achievements of this project have accumulated over 1 billion yuan in economic benefits, and produced a wide range of social benefits, playing a role in serving major and key national projects.

College students are enthusiastic about growing rice, but the new agricultural science is not as simple as farming.

  "Breakfast, a bowl of boiled rice with pickles, full of rice, sweet back." Eating his own hybrid rice, Liu Haolin, a sophomore majoring in agriculture at the Agricultural College of Sichuan Agricultural University, has an indescribable satisfaction.

  Recently, the news that sophomores successfully planted hybrid rice appeared in Weibo Hot Search. In late April this year, the Agricultural College of Sichuan Agricultural University held a hybrid rice planting and whole growth period management skill competition. Online registration was full just two minutes after it was opened, and many students failed to sign up. In late September, three hybrid rice plants planted by Liu Haolin’s group successfully passed the teacher’s acceptance. Some people praised and others scoffed at the fact that the sophomore boys planted hybrid rice, thinking that it was just the basic skill of agronomy, and some people thought that studying agriculture was just learning to farm.

  Does the popularity of planting competition in agricultural colleges mean that planting is a necessary skill for agronomy majors? What is special about the hybrid rice planted in the competition? Under the background of new agricultural science, what changes have taken place in agricultural professional education in colleges and universities? A few days ago, the reporter of Science and Technology Daily conducted relevant interviews.

  Cutting-edge technology into agricultural competition

  In the eyes of many people, the major of agronomy is to learn farming, and you can learn how to do species work at home without even going to college, so that the farmland can be productive. However, in Liu Haolin’s view, studying agronomy is to contribute to the national agricultural development. "Agronomy taught me how to greatly increase production, how to scientifically farm, how to cultivate new varieties, etc., which is absolutely different from farming at home."

  "This is the public’s misunderstanding of agronomy, which is a modern science that uses science and technology to arm crop production." Ren Wanjun, deputy dean of the Agricultural College of Sichuan Agricultural University, said that planting is one of the most basic skills in agronomy, but in addition to its production function, planting is more important to lay the foundation for theoretical research on crop biology and ecology, new variety breeding, cultivation technology innovation and management model innovation.

  During the competition, in order to let students feel the cutting-edge technology in the field of planting, the college applied the latest achievements of the national key research and development plan to all aspects of the competition.

  In terms of varieties, combined with the adaptability of mechanical transplanting of hybrid indica rice and the demand for high quality and high efficiency, the competition adopted the newly established variety screening index system with "daily yield" and "good taste" as the core; In the two links of seedling raising and planting intubation protection, the high-efficiency seedling raising technology and the green cultivation technology of high-quality hybrid rice with good quality and high quality are adopted respectively.

  The college will organize special personnel to carry out training on the technical application of each link. "The purpose of the training is to enable students to personally experience and master these advanced technologies and help them better cultivate rice." Ren Wanjun said.

  In August, pests first appeared, and Liu Haolin, who wanted to kill insects quickly, accidentally took too many drugs and burned seedlings. As a result, there was no progress when it was time to heading. Liu Haolin, who was thinking about how to feed rice while eating and sleeping, suddenly thought of what the teacher had said in class, so he solved this problem. He said: "Agriculture needs to combine theory with practice. Although there will be setbacks during the competition, the key is to find problems and master methods through practice."

  "The whole competition is equivalent to laboratory planting, and every link can be managed accurately. Because there are fewer seedlings planted in the laboratory, the lighting conditions and soil conditions are not well planted in the field, so its management is more difficult than field planting, but it also exercises and tests students more. " Ren Wanjun said that for scientific research and teaching, laboratory planting is of great value, because each link is controllable, so we can know more clearly the reasons for some phenomena in each link and determine the effect of each technical measure.

  He said that any agricultural research results need to be combined with laboratory and field, and repeated experiments. After the results are planted in the laboratory, they need to be tested by field experiments before they can be popularized, which takes a long period.

  Cross-discipline to create comprehensive talents

  The fiery competition is actually a microcosm of the construction of new agricultural science. In June this year, the Anji Consensus — — The announcement of China Declaration on the Construction of New Agricultural Sciences marks the official start of the construction of new agricultural sciences in China, and the development of higher agricultural and forestry education has entered a new era. Since the announcement of the new agricultural science, what changes have been made in the education of agricultural specialty in colleges and universities?

  "The focus of the new agricultural science is to transform the traditional agronomy specialty with modern biotechnology, engineering technology, information science and technology, so we should focus on combining these technologies with modern agronomy and integrating them into the teaching, scientific research and practice of personnel training." Ren Wanjun said that to take the road of innovation and subject integration, we should not only integrate the latest scientific research achievements and modern high-tech into specialty construction and course teaching, but also deepen the interdisciplinary, strengthen the construction of emerging interdisciplinary fields such as mechanized crop cultivation, precision cultivation, intelligent agriculture and biological breeding, put forward new theories and methods, realize the modernization of agronomy, and let universities lead the development of new agronomy.

  The reporter saw that in the training plan of the college, there are not only basic and professional theoretical courses such as plant physiology, soil and fertilizer science, crop cultivation science, farming science and crop breeding science, but also general courses such as English, ideological and political science, mathematics, chemistry and biology, as well as ideological and political courses for agricultural students to "learn from agriculture and love agriculture" and "strengthen agriculture and promote agriculture". At the same time, interdisciplinary courses such as intelligent agricultural technology and application, agricultural economy and management, plant biotechnology, molecular biology, agricultural industrialization, agricultural standardization and crop production mechanization have also been included in the training plan. Ren Wanjun said that agricultural production should take the modernization road of mechanization, standardization and informationization. As a high-tech discipline, agronomy is a complex comprehensive specialty, so the cultivation of agricultural talents should also be a systematic comprehensive project.

  Innovation and entrepreneurship take on the responsibility of revitalization

  "The most distinctive feature of the new agricultural science in our college is to cultivate students ‘ Willing, capable, hardworking and practical ’ ‘ Sigan ’ Traits. " Ren Wanjun said that agronomy itself has high practical requirements. Under the background of new agricultural science, the mastery and application of technology need to further deepen the practical requirements of agronomy. Therefore, it is particularly important to cultivate students’ practical ability and innovative consciousness.

  "In the process of practical teaching, the most important thing is to cultivate students’ innovative and entrepreneurial ability. In addition to learning the basic operation of planting, students should learn how to solve problems, including theoretical problems, technical problems, production problems, management problems, benefit problems, etc., and constantly optimize their thinking and methods for solving problems. " Ren Wanjun said that agricultural science and technology are constantly developing, and students need to have the ability to innovate, not only to absorb and master new things, but also to continuously develop and create new theories and technologies.

  In order to closely combine practical teaching with the cultivation of innovation and entrepreneurship, the college has established a training path of undergraduate talents with "indoor and field combination, scientific research transformation teaching, classroom cooperation, innovation and entrepreneurship education". In addition to setting up various skills competitions such as hybrid rice planting and whole growth period management, seed quality testing, specimen making, etc. in the school, the college also allows every undergraduate to "join the team, each with a project", so that every student can enter the teacher’s research team, participate in scientific research projects, and cultivate innovation and entrepreneurship ability in scientific research practice.

  In addition, the college has more than 30 off-campus practice bases and expert compound, which can carry out teaching and scientific research practice for students to complete course practice and graduation practice, and serve local economic development while being familiar with actual agricultural production and work. Ren Wanjun said that the College closely combines talent training with the abundant crop resources and diversified production structure in Southwest China, meets the new requirements of the integration and development of rural primary, secondary and tertiary industries in Southwest China through co-construction and co-education in Industry-University-Research, implements the combination of agriculture, education and Industry-University-Research cooperation, and strives to improve students’ comprehensive ability, cultivate a group of high-quality compound agronomists with multi-disciplinary backgrounds, cultivate more new talents who know and love agriculture, and shoulder the responsibility of rural revitalization.

Can new energy vehicles run fast without subsidies?

  Recently, the largest public centralized charging station in Henan Province — — "United Fast Charging" was put into operation in Zhengzhou, and all charging piles were charged with high-power DC fast charging, which can meet the requirements of charging more than 100 new energy vehicles at the same time.

  After the subsidy retreat, domestic new energy vehicles will not only face competition with traditional fuel vehicles, but also compete with foreign new energy vehicle brands. Impressing consumers with suitable and high-quality products may be the most effective means for new energy vehicle manufacturers to resolve market risks. The core of competition among new energy automobile manufacturers is the competition of product technology and service.

  With the end of the first half of 2019, new energy vehicles have truly entered the post-subsidy era.

  Chen Shihua, Assistant Secretary-General of China Association of Automobile Manufacturers, said that the current new energy vehicle market is still a market stimulated by policies, and with the support of national and local policies, it is in a rapid rising cycle. The decline of this subsidy is expected to have little long-term impact on the industry, and the previous prediction of the annual production and sales of 1.6 million new energy vehicles in 2019 will remain unchanged.

  After waiting and seeing, the price increase is inevitable.

  June 25th is the last day of the switching period between the subsidy policy for new energy vehicles in 2018 and the subsidy policy for new energy vehicles in 2019. Since June 26th, consumers have enjoyed the most subsidies or reduced them by 58%.

  "The withdrawal of subsidies mainly takes into account that the development of the new energy automobile industry has begun to take shape." Zhou Yi, assistant researcher of the Ministry of Industry of the State Council Development Research Center, said. Before 2014, the output of new energy vehicles was very small, less than 20,000. In 2014, the output jumped to 78,000. In 2018, the sales of new energy vehicles in China reached 1.256 million, accounting for more than half of the world’s total, with remarkable achievements.

  In fact, the rapid growth of new energy vehicles in China in the past is inseparable from subsidies. According to the "Announcement on the Preliminary Review of Subsidies for the Promotion and Application of New Energy Vehicles in 2016 and Previous Years" published on the website of the Ministry of Industry and Information Technology in March this year, nearly 12.6 billion yuan of subsidies will be distributed to nearly 100 enterprises, of which BYD will become the biggest beneficiary with 2.689 billion yuan, and Geely will rank second with 1.111 billion yuan.

  With the subsidy for new energy vehicles declining year by year, independent car companies will naturally be affected to varying degrees, especially whether the price of new energy vehicles will increase, which has become the focus of consumers’ attention.

  The reporter recently visited some 4S stores in Beijing, such as Chery, BYD and GAC New Energy, and has not seen a clear price increase notice. They are all selling cars at the subsidy standard of 2018.

  Chen Shihua said, "At present, the profit rate of new energy vehicles is very low, and it is difficult for car companies themselves to bear the reduction of subsidies." "After the subsidy has dropped, the cost of car companies has increased substantially. If consumers do not accept the price increase, it will be difficult for market demand to start effectively." Cui Dongshu, Secretary-General of the National Passenger Car Market Information Association, said that the subsidy for new energy vehicles is much lower than the cost reduction of car companies, and the profit pressure of new energy car companies is greater. Car companies should not only cover manufacturing costs, but also consider the capital cost of subsidies that are not in place, so they will definitely raise prices.

  Competition will be more intense.

  "In recent years, in addition to the increase in quantity, the quality of new energy vehicles and the development of industrial chain have also been greatly improved." Zhou Yi said.

  From the quality point of view, the battery life is generally on the rise. A-class electric vehicles with a standard cruising range of more than 400 kilometers have become the mainstream, and the intelligent interconnection is also developing continuously. The level of automatic driving test is getting higher and higher, and the localization replacement rate and globalization level of parts and components are also constantly improving. From the industrial chain point of view, the upstream and downstream industrial chains of new energy vehicles are more complete, and a number of excellent enterprises have emerged in the fields of power batteries, non-battery accessories and other parts, complete vehicles such as independent brands and new Internet forces, and manufacturing and operation of charging piles.

  And the fast-growing new energy automobile industry will be affected after stepping on the "brake" of subsidy retreat?

  "The challenge is that the competition will be more intense in the future." Zhou Yi said that after the withdrawal of subsidies, domestic new energy vehicles not only face competition with traditional fuel vehicles, but also with foreign new energy vehicle brands, and there is fierce competition within domestic new energy vehicles.

  Lu Fuyong, a lecturer in industrial economy and national economy in university of international business and economics, has been paying attention to the development of new energy automobile industry in recent years. He told reporters that in the era of subsidies for new energy vehicles, there are four aspects of market risks: First, the competition in the overall market will be further intensified, and the subsidy policy will make the competition more intense, and the industry will gradually move toward the survival of the fittest. In this process, traditional car companies still have certain competitive advantages. Second, the real demand of consumers will gradually become clear. In the past, due to the support of policies, the market has always overestimated the real demand of consumers, and it is very likely that the market demand will fall back in the short term. The third is the risk of capital. In recent years, the new forces of car-making have risen rapidly with the help of capital. As the sales of new energy vehicles move from hot to stable, there is uncertainty whether these capitals will still be active in the industry. The fourth is the technical service risk.

  Lu Fuyong believes that how to grasp the real needs of consumers in the post-subsidy era and impress consumers with suitable and high-quality products may be the most effective means for new energy vehicle manufacturers to resolve market risks. "In the future, the competition of new energy automobile manufacturers will gradually shift to the comprehensive value competition of products, and the core is the competition of product technology and service."

  Lu Fuyong said that with the growth of new energy vehicles and the extension of service life, traffic and safety accidents related to new energy vehicles will further increase, and the short service life of new technologies will increase product risks; At the same time, new energy vehicles recalled due to product quality problems are also accumulating. The core to solve these problems is still to improve product quality and technical services, which is also the main difficulty faced by new energy vehicle manufacturers.

  Intelligentization will become the commanding height.

  "In 2019, China’s automobile market will still run at a low speed, but new energy vehicles will continue to grow. New energy automobile products should be customized in design, intelligent in function and platformized in development. " Shi Jianhua, Deputy Secretary-General of China Automobile Industry Association, said that with the rapid advancement of scientific and technological revolution, the new generation of information technologies such as 5G, cloud computing and artificial intelligence are deeply integrated with automobile transportation and other fields, which constantly promotes the formation of multi-dimensional information interaction networks between cars, roads, people and clouds, and people’s production and lifestyle are undergoing profound changes. Smart cars have become the commanding heights of the future development of the automobile industry.

  Shi Jianhua believes that in the future, the automobile industry should take green and intelligence as the development direction, and will focus on breaking through the key components of fuel cell technology and related industrial chains, advance the research and development and industrial application of intelligent driving technology, enhance the green and intelligent level of the industry, and accelerate the development of new energy and intelligent networked vehicles.

  Zhou Yi said that at present, there is a trend of "interconnection, autonomous driving, sharing and electrification" in the global automobile industry, and the networking of vehicles, autonomous driving and electric vehicles are closely related, and with the rise and application of 5G technology, it is expected that the application scenarios of electric vehicles under 5G will be more abundant in the future. In this context, the new energy vehicle market will be polarized in the future, and a few car companies will stand out because of their technical and cost advantages.

  "Whether new technologies and new industrial formats such as autonomous driving, car networking, intelligent transportation and driverless taxis can be commercialized on a large scale depends entirely on many factors such as cost, technology maturity and consumer acceptance." Zhou Yi said, but what is certain is that China has taken the lead in international exploration in these fields due to its huge market scale and abundant capital market, and it is expected to lead the global development in the future.

At the age of 40, it’s time to prevent osteoporosis.

  After the solar term in beginning of winter, the temperature plummeted. According to the annual clinical consultation, the risk of falls and fractures of the elderly will show an upward trend. This is related to environmental factors such as reduced activity in winter, thick clothes and slippery roads, and also related to physical factors such as aging and degeneration of various organs of the elderly. Today we will focus on the problem of osteoporosis. According to the epidemiological survey of osteoporosis in 2018, 6% of male patients with osteoporosis over 50 years old, 32.1% of female patients, and 51.6% of female patients over 65 years old in China. Our country not only has a high proportion of osteoporosis population, but also does not pay enough attention to osteoporosis. The bone mineral density of people over 50 years old is only 3.7%. In fact, both men and women have entered the early stage of bone loss since the age of 40, and we should prevent osteoporosis from this time.

  1 minute self-examination of osteoporosis risk

  By answering the 1-minute osteoporosis risk test of the International Osteoporosis Foundation, you can quickly know whether you have the risk of osteoporosis.

  1. Parents have been diagnosed with osteoporosis or have been fractured after a light fall.

  2. One of the parents has a hunchback.

  3. The actual age is over 40 years old.

  4. Is there a fracture due to a light fall in adulthood?

  5. Do you often fall down (more than once last year) or worry about falling down because you are weak?

  Has the height decreased by more than 3 cm after 6.40 years old?

  7. Is it underweight (body mass index value is less than 19)

  8. Have you ever taken steroid hormones such as cortisone and prednisone for more than 3 months (cortisone is often used to treat asthma, rheumatoid arthritis and some inflammatory diseases)?

  9. Do you have rheumatoid arthritis?

  10. Have you been diagnosed with gastrointestinal diseases or malnutrition such as hyperthyroidism or hyperparathyroidism, type 1 diabetes, Crohn’s disease or celiac disease?

  11. Do you stop menstruating at or before the age of 45?

  12. Have you ever stopped menstruating for more than 12 months except pregnancy, menopause or hysterectomy?

  13. Did you have your ovaries removed before the age of 50 and didn’t take estrogen/progesterone supplements?

  14. Do you often drink a lot (drink more than two units of ethanol every day, which is equivalent to 570ml of beer, 240ml of wine or 60ml of spirits)?

  15. Currently used to smoking or used to smoke.

  16. Exercise less than 30 minutes a day (including doing housework, walking and running, etc.)

  17. Can’t you eat dairy products and don’t take calcium tablets?

  18. Have you been engaged in outdoor activities for less than 10 minutes every day and have not taken vitamin D?

  As long as the answer to one of the above questions is "yes", it is positive, suggesting the risk of osteoporosis, and suggesting bone mineral density testing or evaluating the risk of fracture.

  Bone mineral density detection is suitable for the following groups

  It is not necessary for everyone to do bone mineral density test. Compare the following self-test options to see if you need to have a bone mineral density test.

  1. Women over 65 years old and men over 70 years old, regardless of other risk factors for osteoporosis.

  2. Women under 65 and men under 70 have one or more risk factors for osteoporosis.

  ■ A slight collision or fall will cause a fracture.

  ■ Adults with low sex hormone levels caused by various reasons.

  ■ Those with diseases affecting bone metabolism or a history of using drugs affecting bone metabolism.

  ■ Patients receiving or planning long-term glucocorticoid treatment

  ■ Small and thin people

  ■ Long-term bedridden patients

  ■ People with chronic diarrhea

  ■ The answer to the 1-minute osteoporosis risk test is positive.

  Normal osteoporosis

  Remember "Five Origins and Three Stages" in Prevention and Control

  The prevention and treatment of osteoporosis should follow five principles. First, increase bone mass and increase bone peak value; The second is to delay bone loss; Third, inhibit secondary hyperparathyroidism; The fourth is to prevent the first fracture; Fifth, reasonable dietary structure and nutritional composition ratio, quitting bad eating habits, increasing calcium intake, participating in moderate exercise and increasing sunshine.

  Then, according to these five principles, the measures to prevent osteoporosis can be divided into three stages according to age: primary prevention, secondary prevention and tertiary prevention.

  The primary prevention of osteoporosis is to start from childhood, to reach the highest bone mass (peak bone mass) in one’s life from childhood and adolescence to around 30-35 years old, with the goal of avoiding or alleviating the occurrence of osteoporosis as much as possible. There are mainly the following measures.

  Reasonable dietary structure: milk is the most ideal calcium source, with 120mg of calcium per 100ml of fresh milk and a calcium absorption rate of 30%. The daily intake of calcium can be ensured by taking 500ml for adults, 750ml for children and 800ml for adolescents.

  Choose foods with high calcium content: sesame sauce, shrimp skin, dried seaweed, kelp, milk, bean products and cheese are all foods with high calcium content.

  Vitamin D intake: The daily intake of vitamin D is 400IU, and the vitamin D content in foods such as cod liver oil, canned sardines, egg yolk, shad and chicken liver is high. Sunlight irradiation is also one of the important ways to supplement vitamin D. Walking in soft sunshine for 40 minutes can ensure the vitamin D needed by the body. It is best to choose the irradiation time before 10 a.m. or after 3 p.m., so as to avoid too strong sunlight damaging the skin and eyesight.

  Moderate exercise: participating in moderate exercise is helpful to increase bone mass and increase the peak bone mass.

  Adhere to a healthy lifestyle: not addicted to alcohol and tobacco; Drink less coffee, strong tea and carbonated drinks; Less salt and less sugar.

  When people reach middle age, they reach the secondary prevention stage of osteoporosis. The core of prevention at this stage is to delay the loss of bone mass in middle age and try to avoid the first osteoporotic fracture. Women aged 40-49 and men aged 40-64 enter the prophase of bone loss: the annual bone loss rate of women is 0.4%-0.6% and that of men is 0.3%-0.5%. Women enter the period of rapid bone loss 1-10 years after menopause, and the rate of bone loss is obviously accelerated, while men do not have the period of rapid bone loss. In addition to food supplement, physical exercise and a good lifestyle, the main preventive methods need to be supplemented with vitamin D and appropriate calcium. The recommended intake of vitamin D for adults is 400IU/d, and the maximum tolerable intake is 2000IU/d. When vitamin D is used for prevention and treatment of osteoporosis, the dosage is 800-1200IU/d..

  The tertiary prevention of osteoporosis is the stage of mending after the sheep is dead, mainly aimed at the elderly, which is mainly reflected in inhibiting bone resorption, reducing bone turnover rate and preventing accidental injuries and fractures. Osteoporosis can be treated by supplementing calcium and vitamin D and taking anti-osteoporosis drugs under the guidance of professional doctors, so as to avoid osteoporotic fractures and re-fractures as much as possible.

  Calcium supplementation alone cannot replace treatment.

  The daily calcium intake standard recommended by China Nutrition Association is: 400mg; from birth to 6 months; 600mg; for 6-12 months; 800-1200mg; under 10 years old; 11-24 years old 1200-1500mg;; 1400mg; for pregnant or lactating women over 19 years old; Postmenopausal and postmenopausal women who did not take estrogen 1500mg;; Take estrogen 1000mg; for postmenopausal and postmenopausal women; Middle-aged male 1000mg;; 1000-1500mg for the elderly.

  However, calcium supplementation alone cannot replace the treatment of osteoporosis. Osteoporosis patients can’t overcome the obstacle of calcium utilization by bones only by taking calcium orally, so they should be treated regularly under the guidance of doctors.

  About 30% of elderly people over 60 years old and postmenopausal women have gastric acid deficiency. If they have flatulence and constipation after taking calcium carbonate, they should change to calcium citrate. The absorption of calcium citrate is independent of gastric acid and can prevent kidney calculi, which is especially suitable for those with gastric acid deficiency.

  However, whether calcium supplementation is needed or not should be decided by consulting a specialist in a regular hospital and doing a bone mineral density examination. There is a threshold for calcium absorption. Excessive supplementation is not only a waste, but also can lead to kidney calculi’s disease, ectopic calcification and atherosclerosis. Kidney calculi, patients with advanced bone metastasis, hypercalcemia and cardiac and renal insufficiency are forbidden to supplement calcium.

Thousands of people such as Musk signed an open letter, and the development of artificial intelligence endangered the "control of civilization"?

  BEIJING, March 30 (Xinhua)-The American drama westworld and the Hollywood movie Terminator have described that the "awakening" of artificial intelligence (AI) may endanger human beings. Recently, concerns in science fiction films have come into reality, and many "big brothers" in the artificial intelligence industry have suddenly called for suspending the development of more powerful AI systems, suggesting that AI systems with human-level intelligence may "pose potential risks to society and mankind".

  Where do their concerns come from? Will the development of artificial intelligence endanger the "civilization control" of human beings? Has the development of AI reached a turning point where the "pause button" needs to be pressed?

  An open letter, four questions about AI risk

  Recently, elon musk, an American billionaire, and Yoshua Bengio, a top expert in the field of artificial intelligence and winner of Turing Prize, signed an open letter calling for suspending the development of AI systems more powerful than GPT-4 for at least six months, calling it "a potential risk to society and mankind".

  An open letter calling for the suspension of giant AI training. Image source: "Future Life Institute" website

  The open letter published on the website of the Future of Life Institute, a non-profit organization, advocates that before developing a powerful AI system, it should be confirmed that the impact is positive and the risks are controllable.

  The letter details that the AI system with human intelligence may bring great risks to society and human beings, saying that "this point has been recognized by a lot of research and top AI laboratories" and throws four questions in succession:

  -Should we let machines flood our information channels with propaganda and lies?

  -Should we automate all the work, including those that are satisfactory?

  -Should we develop non-human thinking that may eventually surpass us in number, surpass us in intelligence and be able to eliminate and replace us?

  -Should we risk losing control of our civilization?

  The open letter pointed out that if such suspension cannot be implemented quickly, the government should step in and take measures. In addition, "AI Labs and independent experts should take advantage of this suspension to jointly develop and implement a set of shared security protocols for advanced AI design and development, and be strictly audited and supervised by independent external experts".

  The letter also called on developers and policy makers to cooperate to greatly accelerate the development of a powerful AI governance system. This should at least involve regulatory agencies, auditing and certification systems, monitoring and tracking high-performance AI systems, liability issues after artificial intelligence causes injuries, and providing public funds for AI technology security research.

  At the end of the open letter, it is mentioned that today, our society has suspended other technologies that may have disastrous effects, and the same should be true for artificial intelligence. "Let’s enjoy a long ‘ Summer of AI ’ Instead of entering autumn unprepared. "

  Technology, ethics and interests call for slowing down.

  It is not difficult to see from these contents that the supporters of the open letter are more concerned about the possible "barbaric growth" of artificial intelligence and the social and ethical problems that its development may bring.

  As mentioned in the open letter, this suspension does not mean suspending the development of artificial intelligence as a whole, but "taking a step back" from the dangerous competition. The research and development of artificial intelligence should re-focus on making today’s powerful and advanced systems more accurate, safe, interpretable, transparent, robust, consistent, credible and reliable.

  Gary Marcus, a professor at new york University, said, "This letter is not perfect, but the spirit is correct." He believes that people need to slow down until they can better understand the consequences of all this.

  At present, the open letter has been signed by thousands of people, including Emad Mostaque, CEO of open source artificial intelligence company Stability AI, DeepMind researcher of artificial intelligence company of Google’s parent company Alphabet, computer scientist Stuart Russell and other experts, scholars and technology company executives.

  The "Future Life Research Institute" that issued an open letter was mainly funded by the Musk Foundation and the Silicon Valley Community Foundation. Tesla CEO Musk is applying artificial intelligence to autonomous driving system, and he has been frankly expressing his concerns about artificial intelligence.

  Reuters also said that Europol recently expressed ethical and legal concerns about advanced artificial intelligence such as ChatGPT, warning that such systems may be abused for phishing, false information and cyber crimes. In addition, the British government also announced a proposal to establish an AI regulatory framework.

  On the Internet, this letter also caused heated discussion. Some netizens agreed that people need to know what happened. "Just because we know we can build it doesn’t mean we should build it."

  However, some people doubt Musk’s motivation. "Musk signed it because he wanted to use his artificial intelligence to make money."

  Others analyzed, "This is terrible, but I don’t think some projects need to stop. Technology is developing rapidly and responsible innovation is also necessary. "

  Thinking about the relationship between human beings and AI has never stopped since the birth of technology. The famous physicist Hawking once said, "The successful creation of artificial intelligence is probably the greatest event in the history of human civilization. But if we can’t learn how to avoid risks, then we will put ourselves in a desperate situation. "

  Nowadays, from passing the qualification examination to artistic "creation", AI can do more and more things and go further and further in the direction of "intelligence". At the same time, however, criminal acts such as using AI technology for online fraud and extortion and spreading illegal information are also emerging one after another.

  Different from the long cycle of the transformation of technological innovation achievements in the physical world, AI technological breakthroughs often spread around the world overnight through the Internet. These discussions and concerns are not superfluous until human beings fail to find a proper solution to AI ethics and supervision.

"The harm caused by Japan’s nuclear polluted water discharged into the sea will be global" (international perspective)

  On August 9, more than 20 college students from many places in South Korea formed a "delegation against Fukushima nuclear polluted water discharging into the sea" to hold a protest rally in Tokyo, Japan, and strongly opposed the Japanese government’s plan to force nuclear polluted water discharging into the sea.

  According to media reports, Japan is studying to start the discharge of Fukushima nuclear polluted water into the sea as early as late August. The Japanese government’s behavior of ignoring the legitimate and reasonable concerns of all parties and insisting on promoting the plan of discharging nuclear polluted water into the sea has triggered continuous opposition and criticism from Japan and the international community. All parties urge the Japanese government to fully respond to the concerns of the international community, fulfill its due moral responsibilities and obligations under international law, stop pushing the plan of sea discharge, fully communicate with neighboring countries in a sincere manner, ensure the safe disposal of nuclear polluted water, and accept strict international supervision.

  "The Japanese government should abandon the established route of discharging nuclear polluted water into the sea."

  On August 9, more than 20 college students from many places in South Korea formed a "delegation against Fukushima nuclear pollution" to hold a protest rally near the Prime Minister’s residence and the Ministry of Economy, Trade and Industry in Tokyo, Japan. The students held banners and slogans such as "Oppose the discharge of nuclear polluted water into the sea" and "Don’t pollute everyone’s sea" and shouted slogans such as "Stop Fukushima nuclear polluted water from discharging into the sea" and "Preserve nuclear polluted water on land", and strongly opposed the Japanese government’s plan to force nuclear polluted water to discharge into the sea.

  Park Jae-min, a student from Korea’s Jianguo University who participated in the protest rally, told this reporter that the safety of Fukushima’s nuclear polluted water discharged into the sea has not been fully verified, and it is impossible to eliminate the worries and uneasiness of ordinary people all over the world, including South Korea. South Korea and Japan are close neighbors, and the discharge of Fukushima nuclear polluted water into the sea is bound to do harm to ordinary people in South Korea and seriously affect South Korea’s marine fisheries.

  On August 7th, Japanese citizens’ groups held a theme forum on "Opposing Nuclear Pollution Water Discharging into the Sea" in Nagasaki City. More than 100 citizens and students from Nagasaki and all over Japan attended the forum. In his speech, the host Gu Yazhi said that discharging nuclear polluted water into the sea is to put economic cost above safety, and the Japanese government chose discharging the sea as a simple way to save money out of economic self-interest. Gu Yazhi emphasized that the nuclear polluted water in Fukushima contains a variety of radioactive substances, which is not the same as the waste water generated by normal nuclear power plants. All radioactive wastes generated by nuclear accidents, including nuclear polluted water, should be permanently sealed and kept.

  At the forum, Masahiro Kaoda, a co-representative of the Fukushima Peace Forum, a local civic group in Fukushima Prefecture, pointed out that although various feasible measures can be taken to prevent nuclear polluted water from being discharged into the sea, the Japanese government and Tokyo Electric Power Company have always regarded the sea discharge plan as an "established policy", ignoring many objections, concealing various problems that are not conducive to the nuclear polluted water discharge plan, and constantly pushing forward the sea discharge plan.

  Masahiro Kakuda stressed that Japanese fishing groups insisted on opposing the discharge of nuclear polluted water into the sea and demanded that the Japanese government continue to preserve nuclear polluted water on land. This voice was very strong among ordinary people in Fukushima. However, the Japanese government and Tokyo Electric Power Company turned a blind eye to this and refused to re-study other disposal methods other than discharging nuclear polluted water into the sea. He said, "The Japanese government should abandon the established route of discharging nuclear polluted water into the sea, show courage and make a political decision to re-study the disposal plan of nuclear polluted water."

  From August 4th, the second phase of the 2023 World Conference on the Prohibition of Atomic Bombs and Hydrogen Bombs, sponsored by the Japan National Conference on the Prohibition of Atomic Bombs and Hydrogen Bombs, was held in Hiroshima, Japan. On the morning of the 5th, at the sub-forum to discuss the Japanese government’s nuclear power policy, many experts, scholars and representatives of civic groups once again severely criticized and resolutely opposed the Japanese government’s insistence on promoting the plan of discharging nuclear polluted water into the sea regardless of public opinion.

  In his speech, Professor Emeritus of osaka prefecture university, Mr. Kazuyuki Sawazawa, pointed out that the Japanese government and Tokyo Electric Power Company’s promotion of Fukushima nuclear polluted water to the sea not only violated the relevant provisions of the London Convention on Dumping Waste, but also suspected of violating Japan’s domestic law. The London Dumping Convention prohibits the dumping of radioactive wastes into the sea through artificial structures at sea. As a contracting party to the London Dumping Convention, Japan attempts to discharge the Fukushima nuclear polluted water into the sea, which obviously violates the relevant provisions of the Convention. In addition, at present, the amount of radiation in the space environment in the Fukushima Daiichi nuclear power plant far exceeds the limit measurement, and the discharge of nuclear polluted water into the sea will further increase the amount of radiation in the space environment in this area, which is an illegal act suspected of violating relevant Japanese restrictions and regulations.

  Park Zhenying, a representative of a civic group from Ulsan, South Korea, said in his speech that the current domestic polls show that more than 80% of South Koreans strongly oppose the Japanese government’s discharge of Fukushima nuclear polluted water into the sea. More than 700 citizens’ organizations in South Korea unanimously opposed the Japanese government’s plan to force nuclear polluted water into the sea. Once the nuclear polluted water is discharged into the sea, it means that the impact of the Fukushima nuclear accident will last for 30 years or even longer.

  "It is a barbaric act to force the plan of discharging nuclear polluted water into the sea."

  Li Zaiming, leader of the Common Democratic Party, the largest opposition party in South Korea, said at the symposium on "Preventing Fukushima nuclear polluted water from being discharged into the sea" held by the South Korean National Assembly on the 8th, "Now we should unite and take countermeasures to prevent Japanese nuclear polluted water from being discharged into the sea. Ensuring that future generations can live in a safe and comfortable environment is one of the important responsibilities of our generation. "

  Yu Yuanzhi, member of the Standing Committee of the Common Democratic Party’s "Countermeasures Committee for Preventing Contaminated Water from Discharging into the Sea", said at the forum that the Japanese government could not dispel people’s concerns no matter how unreasonable it claimed to be "safe". The Common Democratic Party will stick to the end and prevent Japan’s nuclear polluted water from being discharged into the sea.

  More than 200 local people, including citizens’ groups in Chungcheongnam-do, South Korea, held a rally on the 5th to condemn Japan’s plan of forcing nuclear polluted water into the sea. The citizens attending the rally said that the discharge of nuclear polluted water into the sea is a disaster for the earth’s ecosystem and all mankind. Local citizens’ groups said: "In order to resist the Japanese nuclear pollution, we will fight with all the people in Chungcheongnam-do to the end."

  South Korea’s Gwangju Citizen Group held a press conference on the 2nd, strongly condemning and protesting the Japanese plan of forcing nuclear polluted water into the sea. The people who participated in the protests said: "It is a barbaric act for Japan to push the plan of discharging nuclear polluted water into the sea. We must not sit idly by and ignore the serious consequences caused by the discharge of nuclear polluted water into the sea. We hope that more people can understand the harmfulness and seriousness of the discharge of nuclear polluted water into the sea through protests. We must stop this behavior and protect our future. "

  "The Japanese government should face up to the concerns of the international community."

  Luke Mani, director and senior researcher of the Solomon Islands Foreign Policy Advisory Secretariat, said in an interview with this reporter that the Pacific island countries are firmly opposed to Japan’s nuclear pollution water discharge plan. Pacific island countries are basically small island countries, and people’s lives depend heavily on marine ecosystems. For example, the most important marine resource of many Pacific island countries — — Tuna is a highly migratory fish, and discharging nuclear polluted water anywhere in the Pacific Ocean will put this important economic and food resource in danger. "Tunas from Pacific island countries are not only exported to Japan, but also to Europe, so the harm caused by Japan’s nuclear pollution water discharging into the sea will be global."

  Tillman Ruff, co-chairman of the Australian International Doctors Organization for the Prevention of Nuclear War and co-founder of the International Movement for the Abolition of Nuclear Weapons, said in an interview with the media a few days ago that Japan’s plan to discharge nuclear polluted water into the sea violated international conventions such as the United Nations Convention on the Law of the Sea and the London Dumping Convention, and there was also evidence that such behavior would cause extensive and sustained harm and would not bring any benefits. "The Japanese government should face up to the concerns of the international community." Luf said that Japan’s nuclear pollution discharged into the sea will also bring social and economic consequences. The decline of income and export of fishery and other related industries, the strengthening of supervision and restrictions on imports by various countries will all have an impact on Japanese fishermen.

  Weng Shijie, Chairman of Malaysian Center for New Asian Strategic Studies, said in an interview with this reporter that Japan’s insistence on promoting the plan of discharging nuclear polluted water into the sea is irresponsible and detrimental to its international reputation. At the same time, the discharge of nuclear polluted water into the sea will also endanger Japan’s own marine fisheries, and some countries and regions have strictly controlled Japanese seafood.

  Jin Ping, director of the Institute of International Relations of the Royal Cambodian Academy of Sciences, told this reporter that it is a major problem to discharge the nuclear polluted water from Fukushima into the sea. Nuclear polluted water will do harm to marine life, which is not conducive to marine fisheries and poses a threat to human beings. The Japanese government should fully consult with neighboring countries and other stakeholders to effectively dispose of nuclear polluted water in a scientific, safe and transparent manner.

Two Apple 16 yuan netizens shouted: I can’t afford fruit this year.

  Recently, many people have found that the price of fruits has gone up. Fruits such as litchi and cherries, which are usually relatively expensive, are even more expensive than "don’t want to buy" … … According to the data released by the Nutrition Society of China recently, the average daily fruit intake of urban and rural residents in China is at a low level, so experts suggest that a person should eat one catty of vegetables and half a catty of fruit every day. In this regard, the online discussion group went astray, "Fruit is more expensive than meat", which expressed the voice of many netizens in one sentence.

  Fruit is more expensive than meat.

  Netizen: "My heart hurts when I eat."

  Yang Yuexin, chairman of the China Nutrition Society, pointed out that fruits and vegetables provide the human body with daily essential vitamins, minerals, dietary fiber, plant compounds and other nutrients, and are an important part of a reasonable diet. Insufficient intake of fruits and vegetables will increase the morbidity and mortality of hypertension, cardiovascular disease and cancer. Ma Guansheng, vice chairman of the Nutrition Society of China, even suggested that we should ensure that there are vegetables in meals and fruits every day, and one should eat one catty of vegetables and half a catty of fruits every day. Unexpectedly, for this statement, many netizens have exploded, and the topic has gone astray collectively. Listen to the personal experience of netizens:

  "peaches are 20 yuan a catty, and you can’t afford fruit in Hainan"; "Nectarine is 15 yuan a catty, and the taste is still average"; "Six little mango 58 yuan, really can’t afford it"; "A quarter of a watermelon is 17 yuan, which hurts when you eat it"; "Even the unpretentious apples have gone up in price. The total price of two apples with average appearance and taste is 15.98 yuan, almost 8 yuan each. Can you believe it?" Judging from everyone’s feedback, the most "kind" banana is: "Just three bananas are more than a catty, and all the others have started with six pieces. I really can’t afford it."

  Netizens like rabbits sleeping standing up: I can’t afford to eat, and now fruit is more expensive than meat. The glory of the king, a netizen, beat his younger brother: Now the price of fruit is almost catching up with that of seafood. I can’t afford it, so I can only eat one and a half kilos of vegetables.

  The reporter visited the retail terminal

  Three apples are equal to a catty of pork belly.

  On the 14th, the reporter visited several farmers’ markets and supermarkets in Chengdu. The price tag on the fruit and what the vendors said confirmed this: the price of fruit is indeed a bit high recently.

  In a chain supermarket, a catty of cherries is 50 yuan, and a randomly weighed cherry is 1.25 yuan, which can buy an egg with a moderate price; A catty of red Fuji 9.9 yuan, the price of three red Fuji apples can buy a catty of pork belly; Peaches are 16.8 yuan a catty, and the prices of three peaches and a catty of pork belly are also quite the same. "The most expensive is cherries, 50 yuan/kg, cherry 35 yuan/kg, mangosteen 25 yuan/kg, and the cheapest banana is 5 yuan/kg." In an ordinary farmer’s market in Jinjiang District, a fruit merchant told reporters that even the most common apples have sold to 11 yuan for 1 catty, which is several pieces higher than the price at this time last year. In the store next door, the price of cherries has reached 70 yuan/Jin. Vendors say that all the fruits sold in the store are seasonal, and if they are sold out of season, the price is more expensive. "Since the beginning of this year, the price of fruit has risen sharply, and our business is not good." In the farmer’s market, the vendors frowned. As for the reasons, they are not very clear.

  On a nationwide scale, the prices of various fruits are on the rise. According to the monitoring of "National Agricultural Products Wholesale Market Price Information System" of the Ministry of Agriculture and Rural Affairs, among fruits, the biggest increase is Red Fuji apple. Since mid-March, the ring has been showing a year-on-year growth trend, and in the past two weeks, the year-on-year increase has even exceeded 40%. In addition, after the Spring Festival, the price of bananas has been higher than that of the same period last year, and the price of watermelons has been rising year-on-year for nearly two months.

  The fruit retail data released recently in many places also point to the same result: price increase. For example, according to the information released by the Guangdong Provincial Department of Commerce, the average retail price of fruits increased by 0.2% from May 6 to May 12. Due to the rainy weather last week, the transportation and storage costs of fruits increased slightly, driving the overall price of fruits to rise. According to the data of Guangxi Department of Commerce, from May 6 to May 12, the retail price of fruits was 9.46 yuan/kg, and the price increased by 1.94% from the previous month. Among the seven retail fruit varieties monitored, the retail prices of apples, grapes, pears, watermelons and lychees rose.

  Why is fruit so expensive this year?

  Too much rain during the flowering period of Longquan loquat leads to reduced production.

  "The price of loquat is good this year, and the bad ones are removed, and the large and small fruits are packaged and sold. 10 yuan weighs a catty, which is twice as high as last year." Zeng Xinjian is a big loquat planter in Longquan industrial and rural areas, planting 20 mu of loquat. Due to the weather, there is too much rain at the flowering stage of loquat, which leads to insufficient flower bud differentiation, low fruiting rate and nearly half of loquat yield. "In the past, it was possible to produce 1,500 kg to 2,000 kg per mu, but now it is reduced by about 1,000 kg per mu, and the overall output is reduced by at least 40%." Zeng Xinjian said that at the end of April, loquat was about to mature, entered the last expansion period, and suffered from high temperature. The loquat facing the sun all showed "sun scars" to varying degrees. "The taste of this kind of loquat has not changed, but the appearance is very poor, and the purchaser will not want it. It must be picked out when picking." Zeng Xinjian said that as a result, the output has dropped by tens of thousands of Jin, making the overall output drop by 60%, the output drop and the price of loquat rise, making his income this year lower than last year. "Last year, it was able to sell for 120,000 yuan, and this year it is estimated to be only 80,000 yuan."

  Zhang Wenxiang, director of the workers’ and peasants’ villages, said that there are 2,000 mu of loquat planting areas in industrial and rural areas. At present, the purchase price is from 10 yuan to 12 yuan/kg. Due to weather factors, the overall output has dropped this year, but the price has doubled compared with the same period last year. "It is estimated that the income of villagers this year will be the same as last year."

  Large watermelon growers switched jobs, resulting in reduced production.

  At 4 o’clock in the afternoon, Chengdu Pengzhou Mengyang Fruit Wholesale Market was deserted. Last year, the watermelon area where Ren Dajie was located was not like this.

  "Even at this time last year, the watermelons were sold from one end to the other." Sister Ren has been engaged in watermelon business for more than ten years. This year, the price of watermelon is really high and "affordable". At present, Chengdu basically sells local watermelons in Dayi. It has been sold for half a month since 3.1 yuan/Jin -3.3 yuan/Jin, which was listed in early May, and the wholesale price is still maintained at 2.5 yuan/Jin -2.6 yuan/Jin.

  "In previous years, just two or three pieces were listed. In a few days, a large number of watermelons were listed, and they immediately fell to a few hairs." Ren Dajie said that the main reason is the reduction of production. In the past few years, the price of watermelon continued to be low. Last year, it suffered from floods. Large growers lost money year after year, and large growers in other places retreated and changed careers, resulting in a decline in production, at least by half. "As soon as the price is high, many people will stop eating, and fewer people will buy melons."

  Apple and pear suffered from frost during flowering period, resulting in reduced production.

  Speaking of the prices of apples and pears, Deng Darong, who has been a fruit wholesaler for 30 years, said, "It is rare for decades, and the price has risen fiercely, quickly and greatly." Deng Darong said that the apples sold in the market are all from Jingning County, Gansu Province. At present, the wholesale price of apples varies according to the size of the fruit, and the price is 5 yuan/Jin -8 yuan Jin. The reason is that in April last year, when the apple bloomed, the northern part suffered from frost, the fruit setting rate was low, and the output was significantly reduced by 2/3, and the appearance was not good. Since it was purchased and put into storage last year, all localities began to snap up, and the purchase price per Jin was higher than that of previous years. This year,

  "When the output is small, all localities are grabbing goods, and the price is even higher when they grab it." Deng Darong said that in addition to apples, there are pears and other fruits affected by frost. He predicted that although apples and pears are out of stock at present, there is little room for future price increases. "It has reached the peak, and the possibility of rising again is very small."

  Insufficient nutrition of litchi and other reasons lead to reduced production.

  For litchi, this year is a veritable small year. At present, the litchi sold in Chengdu comes from Haikou, and the output has decreased by at least two-thirds. Now the wholesale price is 17 yuan/Jin -18 yuan/Jin. He Qun, the person in charge of Renping Fruit Industry Co., Ltd., said that litchi has a three-year cycle. The year before last and last year were bumper harvest years, and this year happens to be a small year for litchi. "The bumper harvest for two consecutive years has excessively consumed the nutrition of branches. In addition, last year, it was a warm winter in the south, and it was affected by rain, which directly led to a decrease in yield." She predicted that Guangdong litchi would be listed in the next few days, but it was also affected by the reduction in production, and the price dropped slightly, but there was not much room for decline.

  The origin of cherries is not large, and the price has been high over the years.

  And online celebrity fruit "cherries", He Qun said, this is a normal price, which is not much different from previous years. Recently, cherries sold for 70 to 80 yuan a catty, because cherries are produced in Shandong. "People produce early, the output is not big, and the price has been high over the years." He Qun said. Now Wenchuan and Hanyuan cherries have been listed, and the wholesale price is from 15 yuan/kg to 25 yuan/kg, and the price is not much different from previous years.

  National Bureau of Statistics: Prices will not remain high.

  The State Council Press Office held a press conference on the morning of 15th. Liu Aihua, spokesperson of the National Bureau of Statistics, introduced the national economic operation in April this year and answered relevant questions. Liu Aihua said that consumer prices rose by 2.5% in April, an increase of 0.2 percentage points over the previous month. The year-on-year increase of individual varieties has risen, and the year-on-year increase of pork, fresh vegetables and fresh fruits has exceeded 10%. There are two factors that led to the increase in April, one is the increase in pork prices, and the other is that fresh vegetables and fruits with strong seasonality are greatly affected by seasonality. Among them, from the price of fresh vegetables and fresh fruits, these two varieties are obviously affected by seasonal factors of extreme weather, and these seasonal short-term shocks are not sustainable, and the price increase of fresh vegetables and fresh fruits will not last at a high level. From these aspects, food prices have a stable foundation.

Two departments: after 2020, candidates with technical secondary school education will no longer be accepted to take the licensed pharmacist exam.

  BEIJING, March 20 (Xinhua) According to the website of the Ministry of Human Resources and Social Security, National Medical Products Administration and the heads of relevant departments of the Ministry of Human Resources and Social Security answered questions from reporters on the Provisions on the Professional Qualification System for Licensed Pharmacists and the Implementation Measures for the Professional Qualification Examination for Licensed Pharmacists. The relevant person in charge said that this system revision has set up a connection plan for the transition between the old and new systems for technical secondary school education. The transition period will end on December 31, 2020, and candidates with technical secondary school education will no longer be accepted after 2020.

  1. What is the background and significance of the revision of the System Regulations and Examination Measures?

  A: The licensed pharmacist system in China was established in 1994. In 1999, the former National Medical Products Administration and the former Ministry of Personnel jointly revised the Interim Provisions on the Qualification System of Licensed Pharmacists and the Implementation Measures for the Qualification Examination of Licensed Pharmacists (No.34 [1999] of the People’s Republic of China, hereinafter referred to as "Document No.34"), which clearly stipulated that licensed pharmacists should implement a unified national outline, unified examination, unified registration and unified management. Over the years, licensed pharmacists have played an active role in guiding the public to use drugs safely and rationally and ensuring the quality and safety of drugs. By the end of 2018, the number of people who passed the licensed pharmacist qualification examination had reached 1.03 million.

  With the implementation of new laws and regulations and the development of drug safety supervision, some new situations and problems have emerged in the work of licensed pharmacists, and Circular 34 has been unable to meet the needs of the construction and development of licensed pharmacists and supervision. First, with the development of China’s pharmaceutical higher education and the increasing demand for public medication safety, the admission conditions for licensed pharmacists stipulated in Document No.34 can no longer meet the requirements of the current situation. Second, in view of the outstanding problems in the management of licensed pharmacists, such as "certificate attachment" and the failure of enterprises to equip licensed pharmacists as required, Circular No.34 lacks corresponding punishment clauses and grass-roots supervision cannot be relied upon. Third, the administrative subject of the implementation of the current system has changed several times.

  In order to meet the needs of reform and development, rationalize the management rights and responsibilities of licensed pharmacists, speed up the construction of licensed pharmacists, and ensure the safe and effective use of drugs by the public, the two departments revised Circular 34 on the basis of fully listening to opinions from many parties.

  Two, compared with the original system, what are the main changes in the "system regulations" and "examination methods"?

  A: First, improve the entry threshold for licensed pharmacists’ academic qualifications, adjust the minimum academic qualifications from technical secondary school to junior college, and appropriately increase the working years of candidates in related majors in pharmacy (Chinese pharmacy). The second is to carry out information management on the registration of licensed pharmacists nationwide, establish credit records of licensed pharmacists, and conduct credit management on practice activities. The third is to clarify the punishment measures for licensed pharmacists and practicing units, and to restrict licensed pharmacists with bad information records when applying for registration. The fourth is to strengthen the operability of linking the professional qualification of licensed pharmacists with the intermediate professional title of pharmacy. Fifth, it is clear that Hong Kong, Macao and Taiwan residents are treated equally with mainland residents when they participate in national licensed pharmacist qualification examination, registration, continuing education and practice. Sixth, adjust the examination period from two years to four years, and extend the examination period appropriately.

  3. What are the specific requirements of the "Regulations" for the qualification examination of licensed pharmacists?

  A: In order to improve the quality of licensed pharmacists, strengthen the professionalism of the team, and highlight the post practice requirements, this revision will adjust the entry threshold for licensed pharmacists’ academic qualifications from secondary school to junior college, and appropriately increase the working years of relevant professional candidates in pharmacy (Chinese pharmacy).

  The "Regulations" clarify that all People’s Republic of China (PRC) citizens and foreigners who are allowed to work in China can apply for the professional qualification examination for licensed pharmacists if they meet one of the following conditions: (1) They have obtained a college degree in pharmacy and Chinese medicine, and have worked in pharmacy or Chinese medicine for 5 years; (two) to obtain a bachelor’s degree or bachelor’s degree in pharmacy or Chinese medicine, and to work in pharmacy or Chinese medicine for 3 years; (3) Having obtained the second bachelor’s degree, graduate class or master’s degree in pharmacy or Chinese pharmacy, and having worked in pharmacy or Chinese pharmacy for one year; (four) to obtain a doctorate in pharmacy and traditional Chinese medicine; (5) Persons who have obtained corresponding academic qualifications or degrees in pharmacy or traditional Chinese medicine will have their working years in pharmacy or traditional Chinese medicine increased by one year.

  4. How do the Examination Measures stipulate the conditions for applying for some examination subjects with exemption?

  A: The "Examination Measures" canceled the original working years for the conditions for applying for some examination subjects that are exempt from examination. In accordance with the relevant provisions of the state, those who have obtained senior professional titles in pharmacy or medicine and work in pharmaceutical posts may be exempted from taking the examination of pharmaceutical professional knowledge (1) and pharmaceutical professional knowledge (2), and only take the examination of pharmaceutical management and regulations and pharmaceutical comprehensive knowledge and skills; Those who have obtained the senior professional title of Chinese medicine or Chinese medicine and work in the post of Chinese medicine can be exempted from the examination of Chinese medicine professional knowledge (1) and Chinese medicine professional knowledge (2), and only take the examination of pharmaceutical affairs management and regulations and comprehensive knowledge and skills of Chinese medicine.

  Applicants with senior titles who meet the requirements of exemption from the two subjects must work in pharmacy or traditional Chinese medicine and obtain senior titles in pharmacy or medicine, and their qualifications for senior titles should be obtained before the deadline for registration. Those who have worked in pharmacy or Chinese pharmacy and obtained senior professional titles in pharmacy or medicine but have not been employed in the corresponding positions may apply for the exam.

  V. What transitional policies or measures are there for the applicants with technical secondary school education in this revision?

  A: In order to protect the legitimate rights and interests of candidates, this system revision has set up a bridging scheme for the transition between the old and new systems for technical secondary school education, with the transition period ending on December 31, 2020. Those who meet the requirements of the original No.34 document and register for the examination in 2018 and 2019, the validity period of the examination results shall be implemented according to the original provisions of 2 years; Those who sign up for the exam in 2020 should complete all the exam subjects within that year, and will no longer accept candidates with secondary school education after 2020.

  Six, how to manage the continuing education of licensed pharmacists, and how to effectively link the registration management with continuing education?

  A: Licensed pharmacists should receive continuing education, update their professional knowledge and improve their professional level in accordance with the relevant provisions of the national continuing education for professional and technical personnel. The state encourages licensed pharmacists to participate in practical training. The continuing education credits of licensed pharmacists shall be recorded in the national licensed pharmacist registration management information system in time by the continuing education management institution.

  7. How are the professional qualifications and professional titles of licensed pharmacists linked?

  A: In order to implement the relevant requirements of the reform of the central professional title system and promote the effective connection between the professional qualification system and the professional title system, the "System Regulations" clearly stipulates that professional and technical personnel who have obtained the professional qualification of licensed pharmacists can be recognized as having the title of competent pharmacist or competent Chinese pharmacist, and can be used as a condition for applying for a higher-level professional title. The unit selects the best one according to the needs of the work.

  Eight, the "Regulations" on the "Licensed Pharmacist Registration Certificate" linked to other acts of what punishment?

  A: In order to solve the problem of law enforcement at the grass-roots level, the "Regulations on the System" stipulates a number of measures to solve the regulatory problems such as the on-the-job absence of licensed pharmacists and the affiliation of the Registered Certificate of Licensed Pharmacists. For example, the second paragraph of Article 13 stipulates that applicants for registration must abide by the law and discipline, abide by the professional ethics of licensed pharmacists, and have no bad information records. Article 26 stipulates that units that fail to equip licensed pharmacists according to regulations shall be ordered by the local drug supervision and administration department at or above the county level to equip them within a time limit, and shall be punished in accordance with relevant laws and regulations. Article 28 stipulates that if a licensed pharmacist registration certificate is obtained by cheating, bribery or other improper means, the licensed pharmacist registration certificate shall be revoked by the issuing department and the licensed pharmacist shall not be registered within three years; If a crime is constituted, criminal responsibility shall be investigated according to law. It is strictly forbidden to link the Licensed Pharmacist Registration Certificate. If the registered unit of the holder is inconsistent with the actual work unit, the Licensed Pharmacist Registration Certificate shall be revoked by the issuing department and recorded in the national licensed pharmacist registration management information system as personal bad information by the department responsible for drug supervision and administration. Units that buy, sell or lease the Licensed Pharmacist Registration Certificate shall be punished in accordance with relevant laws and regulations.

  The "Regulations on the System" clarifies the punishment measures for the violations of licensed pharmacists and practicing units, so that grass-roots supervision has laws to follow. When applying for registration of licensed pharmacists with bad information records, the registration will not be approved until the bad information records are revoked. Through the establishment of licensed pharmacists’ integrity records and licensed pharmacists’ big data management, we will increase the crackdown on licensed pharmacists’ "hanging certificates" and establish a normalization mechanism for "hanging certificates" governance.

  9. What are the new regulations for Hong Kong, Macao and Taiwan residents in this revision?

  A: In order to further facilitate the work and life of Hong Kong, Macao and Taiwan residents in the Mainland (Mainland) and promote the technical exchange of pharmaceutical professionals and technicians, the "System Regulations" has specially added relevant provisions for Hong Kong, Macao and Taiwan residents to apply for the professional qualification of licensed pharmacists, making it clear that Hong Kong, Macao and Taiwan residents’ application for national licensed pharmacist qualification examination, registration, continuing education, practice and other activities, just like mainland (Mainland) residents, should be handled with reference to relevant regulations.

  X. How to promote the follow-up work after the promulgation of the "System Provisions" and "Examination Measures"?

  A: We will do a good job in the following four aspects: First, we will do a good job in organizing and implementing the system. Carry out various forms of publicity and policy interpretation, so that the majority of pharmaceutical technicians can fully know, understand and support the newly revised "System Provisions" and "Examination Methods". Second, taking the opportunity of system revision, we will carry out centralized rectification of licensed pharmacists in pharmaceutical retail enterprises to promote the healthy and benign development of licensed pharmacists’ professional qualification system. The third is to pay close attention to the revision of the "Administrative Measures for the Registration of Licensed Pharmacists" and other supporting documents. The fourth is to implement the development goals and tasks of licensed pharmacists in the "Thirteenth Five-Year National Drug Safety Plan", strengthen the supervision and inspection of licensed pharmacists in retail pharmacies, standardize the practice behavior of licensed pharmacists, and guide and urge enterprises to implement the main responsibility of licensed pharmacists.
