BEIJING, Sept. 26 (Xinhuanet) -- Although it is home to traditional Chinese medicine (TCM), China must do much more to improve its academic research capacity for acupuncture, a form of TCM, to take the lead worldwide on both the academic and clinical sides.At present, among all academic theses on acupuncture indexed by the Science Citation Index (SCI), a leading world thesis index system, only 5 percent are from the Chinese mainland, according to Wang Linpeng, the director of the acupuncture and moxibustion center of the Beijing Hospital of Traditional Chinese Medicine, which is affiliated with the Capital Medical University.Although Chinese acupuncturists absolutely excel worldwide in clinical practice, "they are not as good as their foreign peers in academic capacity, particularly Western-style research methods and lab experiment design," he told China Daily on Friday during the 2011 International Symposium on Acupuncture. A patient suffering from facial paralysis receives acupuncture treatment at a hospital in Nanjing, the capital of Jiangsu province, on Dec 6, 2010.Studies by TCM practitioners - including acupuncturists - largely focus on their area of specialization, and few are in line with global interest in the medical science that has been proven effective over thousands of years, he said."Chinese TCM practitioners are very good at treating conditions, but they are clumsy at showing how and why it really works in an internationally accepted 'language' and 'manner'," said Gao Sihua, chancellor of the Beijing University of Chinese Medicine."It's especially true in TCM circles, where few Chinese practitioners would regularly follow international academic articles and research trends," Wang said.Measured by the number of articles on acupuncture indexed by SCI, the US and European countries lead globally, he said.

BEIJING, Aug. 16 (Xinhuanet) -- It is widely accepted that obesity leads to an increased risk of health complications, but new studies quoted by media Tuesday challenge the conventional notion.“Our studies challenge the idea that all obese individuals need to lose weight,” said Dr. Jennifer Kuk, assistant professor in York University’s School of Kinesiology & Health Science in Toronto.  One of the studies used data from the Aerobics Center Longitudinal Study consisting of 29,533 individuals and assessed their mortality in 16 years.It found no difference in death risks between normal-weight individuals and obese ones. "Since the obese people did not have greater risk of dying than normal weight individuals, they don’t need to lose weight," said Dr. Kuk.But the finding did not give obese individuals a “free license” to gain weight, Dr. Kuk added. Maintaining weight, eating right and exercising may be better than trying to lose weight in the long run, said Dr. Kuk.

OTTAWA, Sept. 29 (Xinhua) -- Climate change could cost Canada billions of dollars a year by the end of this decade, a government funded study group announced Thursday.The National Round Table on the Environment and the Economy said the cost of climate change for Canada could start at roughly 5 billion Canadian dollars per year in 2020 and increase to between 21 billion and 43 billion per year by 2050. Those costs would come from shoreline damage, public health problems, and disruptions to the economy.It also predicted a slight increase in deaths in major cities from heat and air pollution.The round table researchers estimated the cost of climate change is expected to be roughly 0.8 percent to 1.0 percent of GDP -- or 43 billion Canadian dollars a year -- by 2050, if the problem is allowed to worsen.But the report did not address possible benefits, such as reduced demand for hea

LOS ANGELES, June 20 (Xinhua) -- About 8 percent of children, or nearly 6 million in the U.S., have a food allergy, a much higher rate than previously estimated, a new study suggests.Not only is this estimate higher than some previous research has reported, allergic reactions are often severe and that many kids have more than one allergy, according to the study published online in Pediatrics on Monday.Of the children with confirmed (or probable) food allergies, about 39 percent had had severe reactions in the past, and 30 percent had more than one allergy, the study found.In the current study, researchers at the Northwestern University Feinberg School of Medicine surveyed parents of more than 38,000 children about whether their child had been diagnosed with a food allergy and had one or more of a number of symptoms, including anaphylaxis; swelling of the lips, eyes or face and skin rashes or hives.The study pinned down peanuts (25 percent of food-allergic children), milk (21 percent) and shellfish (17 percent) as the top three allergens.Severe reactions were most common among children with tree nut (more than 50 percent) and fin fish (more than 40 percent) allergies. The reactions were more likely among 14- to 17-year- olds compared with 0- to 2-year-olds, and more likely in children with multiple food allergies, the study found."These findings provide critical epidemiologic information to guide strategies for the prevention of food-induced reactions and for the diagnosis and management of childhood food allergies," the study noted.

WASHINGTON, July 5 (Xinhua) -- Intake of high levels of folate, a water-soluble B vitamin that occurs naturally in food, may reduce colorectal cancer risk, according to a new study published Tuesday in Gastroenterology, the official journal of the American Gastroenterological Association (AGA) Institute. "We found that all forms and sources of folate were associated with lower risk of colorectal cancer," said lead author Victoria Stevens, of the American Cancer Society. "The strongest association was with total folate, which suggests that total folate intake is the best measure to define exposure to this nutrient because it encompasses all forms and sources."Total folate includes naturally occurring food folate and folic acid from fortified foods and dietary supplements.The research team investigated the association between folate intake and colorectal cancer among 99,523 participants in the Cancer Prevention Study II Nutrition Cohort; a total of 1,023 participants were diagnosed with colorectal cancer between 1999 and 2007, a period entirely after folate fortification began. Neither higher nor lower risk was observed during the first two years of follow-up (1999 to 2001), while associations were statistically significantly inverse for the subsequent years (2002 to 2007). The findings of this study add to the epidemiologic evidence that high folate intake reduces colorectal cancer incidence.Folates are essential nutrients needed to make components used for functions required for normal cell growth, including DNA synthesis and repair. Because these processes are critical for cell growth and differentiation, the relationship between folate intake and cancer development has been investigated in several cancers, and most extensively in colorectal cancer.
