BEIJING, July 1 (Xinhuanet) -- China must adopt a holistic approach to addressing food safety challenges connected to the risk of contracting infectious diseases from contact with animals, the World Health Organization (WHO) has said. Peter Ben Embarek, food safety officer at WHO's China office, said the country faces risks connected to the need to produce more meat, eggs and milk to feed its growing population. He said the increased production will ramp up the risk of people being infected by food-borne diseases because of poor slaughtering oversight and the absence of proper surveillance and inspection systems. About 50 percent of pigs in China are slaughtered outside of formal facilities without the inspection of veterinarians or food safety officers. He said poorly trained producers have little or no awareness of food safety or the risk of animal diseases being passed on to humans. Such an environment could lead to the emergence of a new pandemic of influenza. During the past 60 years, 30 percent of the 335 new infectious diseases worldwide were transmitted through food, he said. Yet in many parts of China, public awareness remains low about such things. Xu Aixiang, a 35-year-old resident of Rizhao city in Shandong province, prefers to buy live poultry at local markets. Like many of her neighbors, she takes the chickens she buys home to slaughter them. "I get fresher chickens that are better quality this way," she said. "When vendors sell slaughtered chickens, the meat is no longer fresh and may have had water injected into it to make it heavier." But Ben Embarek cautioned that such live-animal markets are high-risk places for the exchange of viruses and diseases between animals and humans. He said simple and cost-effective measures can be taken to improve such markets' hygiene standards, such as the installation of separate areas to keep live poultry away from customers as well as improving air flow and waste management. Several UN agencies, including the WHO and the Food and Agriculture Organization, called on China to adopt an integrated approach to preventing emerging epidemic diseases and maintaining ecosystem integrity at an event themed "One Health" that convened on Wednesday in Beijing. At the gathering, representatives from the Ministry of Health, the Ministry of Agriculture and the Chinese Center for Disease Control and Prevention shared experiences from efforts to mitigate the H5N1 and H1N1 influenza outbreaks in China and said they were committed to working together in the future. Su Jingliang, an associate professor of preventive veterinary medicine at China Agricultural University, said his lab had detected the outbreak of a new type of flavivirus in ducks that led to a significant fall in egg production at farms in Beijing as well as in Hebei, Jiangxi and Shandong provinces. The pandemic was brought under control in March. No cases of humans contracting the disease have been reported so far but Su said he was concerned about the possibility of farmers becoming infected through close contact and long exposure to sick ducks. He said precautionary measures should be taken in cooperation with the Ministry of Health and other government agencies and checks should be run on people who are at high risk. Xu Wei contributed to this story.
BEIJING, Sept. 25 (Xinhua) -- As China's economy has soared to the second place in the world, the country's scientific strength has also surged -- if only measured by the numbers.Chinese researchers published more than 1.2 million papers from 2006 to 2010 -- second only to the United States but well ahead of Britain, Germany and Japan, according to data recently published by Elsevier, a leading international scientific publisher and data provider. This figure represents a 14 percent increase over the period from 2005 to 2009.The number of published academic papers in science and technology is often seen as a gauge of national scientific prowess.But these impressive numbers mask an uncomfortable fact: most of these papers are of low quality or have little impact. Citation per article (CPA) measures the quality and impact of papers. China's CPA is 1.47, the lowest figure among the top 20 publishing countries, according to Elsevier's Scopus citation database.China's CPA dropped from 1.72 for the period from 2005 to 2009, and is now below emerging countries such as India and Brazil. Among papers lead-authored by Chinese researchers, most citations were by domestic peers and, in many cases, were self-citations."While quantity is an important indicator because it gives a sense of scientific capacity and the overall level of scientific activity in any particular field, citations are the primary indicator of overall scientific impact," said Daniel Calto, Director of SciVal Solutions at Elsevier North America.Calto attributed China's low CPA to a "dilution effect.""When the rise in the number of publications is so rapid, as it has been in China -- increasing quantity does not necessarily imply an overall increase in quality," said Calto.He noted the same pattern in a variety of rapidly emerging research countries such as India, Brazil, and earlier in places like the Republic of Korea."Chinese researchers are too obsessed with SCI (Science Citation Index), churning out too many articles of low quality," said Mu Rongping, Director-General of the Institute of Policy and Management at the Chinese Academy of Sciences, China's major think tank.SCI is one of the databases used by Chinese researchers to look-up their citation performance. The alternative, Scopus, provides a wider coverage worldwide."Chinese researchers from a wide range of areas and institutions are vying for publication, as it is a key criterion for academic appraisal in China, if not the only one. As a result, the growth of quality pales in comparison to that of quantity," said Mu, an expert on China's national science policy and competitiveness.On the other hand, China also falls behind the United States in multidisciplinary research, which is a core engine for scientific advance and research excellence.From 2006 to 2010, China published 1,229,706 papers while the United States churned out 2,082,733. According to a new metric introduced by Elsevier's Spotlight research assessment solution, China generated 885 competencies while the United States had 1,817.In other words, China's total research output is more than half that of the United States, while the number of competencies showing China's strength in multidisciplinary research is less than half that of the United States.Cong Cao, an expert on China's science and technology, put it more bluntly in an article he wrote: "When the paper bubble bursts, which will happen sooner or later, one may find that the real situation of scientific research in China probably is not that rosy."China has been investing heavily in scientific research and technological development in recent years to strengthen its innovative capacity, The proportion of GDP spent on R&D grew from 0.9 percent in 2000 to 1.4 percent in 2007, according to the World Bank.An IMF forecast in 2010 says China now ranks second globally in R&D spending. The IMF calculates China's R&D expenditure at 150 billion U.S. dollars when based on Purchasing Power Parity, a widely used economic concept that attempts to equalize differences in standard of living among countries.By this measure, China surpassed Japan in R&D spending in 2010.Many see China's huge investment in R&D as the momentum behind the country's explosive increase in research papers."Getting published is, in some ways, an improvement over being unable to get published," Mu said. "But the problem is, if the papers continue to be of low quality for a long time, it will be a waste of resources."In China, academic papers play a central role in the academic appraisal system, which is closely related to degrees and job promotions.While acknowledging the importance of academic papers in research, Mu believes a more balanced appraisal system should be adopted. "This is a problem with science management. If we put too much focus on the quantity of research papers, we leave the job of appraisal to journal editors."In China, the avid pursuit of publishing sometimes gives rise to scientific fraud. In the most high-profile case in recent years, two lecturers from central China's Jinggangshan University were sacked in 2010 after a journal that published their work admitted 70 papers they wrote over two years had been falsified."This is one of the worst cases. These unethical people not only deceived people to further their academic reputations, they also led academic research on the wrong path, which is a waste of resources," Mu said.A study done by researchers at Wuhan University in 2010 says more than 100 million U.S. dollars changes hands in China every year for ghost-written academic papers. The market in buying and selling scientific papers has grown five-fold in the past three years.The study says Chinese academics and students often buy and sell scientific papers to swell publication lists and many of the purported authors never write the papers they sign. Some master's or doctoral students are making a living by churning out papers for others. Others mass-produce scientific papers in order to get monetary rewards from their institutions.A 2009 survey by the China Association for Science and Technology (CAST) of 30,078 people doing science-related work shows that nearly one-third of respondents attributed fraud to the current system that evaluates researchers' academic performance largely on the basis of how many papers they write and publish.Despite rampant fraud, China will continue to inject huge money into science. According to the latest national science guideline, which was issued in 2006 by the State Council, the investment in R&D will account for 2.5 percent of GDP in 2020."If China achieves its stated goal of investing 2.5 percent of its GDP in R&D in 2020, and sustains its very fast economic growth over the next decade, it would quite likely pass the U.S. in terms of total R&D investment sometime in the late 2010s," said Calto, adding that it is also quite likely that at some point China will churn out more papers than the United States.According to Calto, China does mostly applied research, which helps drive manufacturing and economic growth, while basic research only accounts for 6 percent, compared with about 35 percent in Germany, Britain, and the United States, and 16 percent in Japan."In the long term, in order to really achieve dominance in any scientific area, I think it will be necessary to put significant financial resources into fundamental basic research -- these are the theoretical areas that can drive the highest level of innovation," Calto said.
SYDNEY, July 15 (Xinhua) -- The world's first drug to increase life expectancy of people with advanced melanoma has been approved for use in Australia, local media reported on Friday.The breakthrough drug Yervoy got approval from the Therapeutics Good Association (TGA) on Friday amid hopes it could add two years to the life of people with the most lethal form of skin cancer but for whom other treatments have failed, the Australian Associated Press (AAP) said.Clearance for the drug's use in Australia follows similar approvals by the U.S. health regulator in March.Yervoy works by attacking and destroying cancer cells.Patients are hooked up to an intravenous drip once every three weeks for a total of four doses.Professor Peter Hersey, consultant immunologist to the Melanoma Institute Australia, said no other drug had improved survival rates like Yervoy."Not all patients respond to it but those who do have a good chance of living longer than they would have otherwise," Hersey told AAP.While it may improve survival rates, Yervoy can produce side effects from diarrhea and vomiting to serious blood infections and kidney failure.The average survival time for people with advanced melanoma is just six months.A global study of 676 people with melanoma found that 45 percent of patients given Yervoy were still alive after one year, according to AAP.More than 20 percent lived at least two years, with a small number managing to survive for six years.A separate study, published in June, which showed similarly improved survival rates for patients with newly diagnosed advanced melanoma, has raised hopes that Yervoy could be made more widely available.Melanoma is the fourth most common cancer in Australia, with 10, 300 people diagnosed each year.
KUBUQI (Inner Mongolia), July 10 (Xinhuanet) -- Amos Nadai, ambassador of Israel to China, spoke highly of the desertification control efforts in the Kubuqi desert of China during an exclusive interview with Xinhuanet here Saturday. "It's a huge area, which is more than half of my country," Nadai said, "I see a lot of planting and it's very beautiful." Nadai was here for the 2011 Kubuqi International Desert Forum held in the Kubuqi Desert, Inner Mongolia of China. As a small country with half of its land being desert, Israel has to work very hard in desertification control and has accumulated a great deal of experience. However, Nadai praised China's efforts in learning new technologies applied in the Kubuqi desert. He said that China takes this very seriously and has developed really rapidly. "They are doing the right thing; they bring here every two years the best experts from all over the world, and they listened carefully," he said. Nadai said that he saw the way people here fight against desertification, develop tourism, boost the use of clean energy, and he was very impressed. That's why Israel is happy to cooperate with China in this field, Nadai said. He also introduced a long-term project that Israel has been working together with China in Xinjiang, which Israel introduces methods to the local farmers that can grow the same amount of crop by using 50 percent less of water. "The local people have learned everything that we can offer them and they can do it alone now," Nadai said. The ambassador, who was awarded the Honorary Citizenship of Chengdu City, the capital of Sichuan Province, Wednesday, said: "I am very very excited for that honor."
HELSINKI, Aug. 21 (Xinhua) -- The Finnish company Spektikor has recently developed a novel type of disposable heart rate indicator, local media reported on Sunday.Different from a conventional heart rate monitor, it is a speed heart rate indicator designed for first aid professionals and specially used in first aids in major accidents, disasters and other crises.According to Spektikor, the product is consisted of a heart rate sensor with two EKG electrodes and a LED indicator, which are connected by a 35-cm-long wire.In operation, the sensor is placed on a patient's chest and the LED indicator is sticked to the patient's cheek. If the heart rate is within the normal range, the LED indicator will flash green with each beat. If the heart rate is dangerously low or high, the light will turn red.The product will help hospital staff speed up their work considerably as it is not necessary to check the pulse manually. In addition to saving time, it will also enhance safety, as the LED indicator can be seen clearly at a glance.The market prospect of the disposable heart rate indicator is quite optimistic as there is a worldwide need for the product.
