WASHINGTON, Nov. 22 (Xinhua) -- Long-term coffee consumption may be associated with a reduced risk for endometrial cancer, according to a study published online Tuesday in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.Edward Giovannucci, professor of nutrition and epidemiology at the Harvard School of Public Health, said that coffee is emerging as a protective agent in cancers that are linked to obesity, estrogen and insulin."Coffee has already been shown to be protective against diabetes due to its effect on insulin," said Giovannucci, a senior researcher on the study. "So we hypothesized that we'd see a reduction in some cancers as well."The researchers observed cumulative coffee intake in relation to endometrial cancer in 67,470 women who enrolled in the Nurses' Health Study. During the course of 26 years of follow-up, researchers documented 672 cases of endometrial cancer.Drinking more than four cups of coffee per day was linked with a 25 percent reduced risk for endometrial cancer. Drinking between two and three cups per day was linked with a seven percent reduced risk.A similar link was seen in decaffeinated coffee, where drinking more than two cups per day was linked with a 22 percent reduced risk for endometrial cancer.Giovannucci said that he hopes this study will lead to further inquiries about the effect of coffee on cancer because in this and similar studies, coffee intake is self-selected and not randomized.

BEIJING, Oct. 21 (Xinhua) -- China on Friday urged the European Union (EU) to recognize its full-market economy status at an early date and properly settle trade disputes amid the tumbling world economy."China hopes Belgium will exert its influence to push for an early recognizing of China's full-market economy status and remind the EU to be cautious on and restrain from using trade remedy measures," Vice Premier Wang Qishan told visiting Crown Prince Philippe of Belgium.Wang urged the 27-member bloc, also China's largest trade partner, to properly settle trade disputes with China during the talks at Diaoyutai State Guesthouse in downtown Beijing.Chinese Vice Premier Wang Qishan (R) shakes hands with Belgian Crown Prince Philippe in Beijing, capital of China, Oct. 21, 2011."China has contributed a lot to the world economy by recording a 9.4 percent growth in the first three quarters of this year while adjusting its economic structure and managing inflation expectations," Wang said.Prince Philippe, accompanied by a 450-member business delegation, is here to tap the Chinese market and seek investments from China, the world's top holder of foreign exchange reserves.During the 10-day trip, the delegation will visit the Chinese cities of Tianjin, Guangzhou, Shenzhen, Shanghai and Chongqing and is expected to sign about 40 contracts.Wang said China will expand two-way investment with Belgium, and enhance support to the two states' small and medium-sized enterprises via the China-Belgium direct equity investment fund.China-Belgium trade has continued to surge since the two states forged diplomatic ties in 1971, when the bilateral trade volume was only 20 million U.S. dollars, much less than the 22.1 billion U.S. dollar record in 2010."We could expand cooperation in two-way investment, trade, finance, chemical industry, environmental protection, logistics, and green economy," Wang said.

BEIJING, Dec. 4 (Xinhua) -- Acclaimed orthopaedic surgeons and experts attending a major conference in Beijing have agreed to build up a platform for international cooperation aiming at jointly coping with medical and social challenges.At the Sixth International Congress of the Chinese Orthopaedic Association (COA) that concluded on Sunday, presidents of more than 80 national and international orthopaedic societies signed a declaration which seeks a model for both developing and developed countries to help reduce medical costs in the aftermath of the global financial crisis.With an aging global population, rapidly rising medical costs have become a heavy financial burden for governments worldwide. Medical insurance cost control has become a hot topic around the world.Bone and joint diseases, infections due to traffic accident traumas and other diseases causing high disability rates have affected millions of people worldwide."One of the objectives of the COA international conference is to provide a platform for medical experts around the world to discuss not only clinical techniques but also medical and social problems," said Professor Wang Yan, chairman of the COA.To fully leverage existing professional knowledge and resources, presidents of orthopaedic organizations attending the conference adopted and released the Beijing Declaration which calls for a platform to enhance global and national collaboration and partnerships among the professions, industries and related patient organizations and disciplines.The declaration also stresses maximizing Internet-based learning and encouraging international exchanges."Worldwide, I have one lament, that we've spent so much money on medical research, but very little on orthopaedics. Most governments are more anxious to fund cancer or infectious diseases," said Professor Michael Huggness, president of the North American Spine Society."We think we're a bit handicapped by not having the money to pursue the research. As we get more sophisticated in our treatment, the price does go up. My expectation is that in another five to 10 years, we'll begin to apply some molecular techniques to assist us in healing. Maybe the price will come down when our knowledge base increases. But I think we'll just have to wait for a bit more research and a bit more basic science.""We definitely will... look into this issue of how we can have a suitably assigned budget from the government for orthopaedic care," said Professor K.M. Chan, from the Prince of Wales Hospital in Hong Kong."At the same time, we use evidence-based medicine to contain the medical cost in orthopaedics with very stringent monitors from the professions. That involves good-practice models, quality insurance and patient safety. With all these, we expect that the profession will be heading forward to join hands with the government to contain the cost."More than 15,000 surgeons, researchers and business representatives from China and abroad are attending the four-day annual conference to share the latest theories and techniques for curing musculoskeletal diseases as well as related social topics.Founded in 1980, the COA now has more than 30,000 registered members and is the largest sub-society of doctors under the Chinese Medical Association. The conference is the largest medical academic event in China.

DOHA, Jan. 18 (Xinhua) -- Visiting Chinese Premier Wen Jiabao said here Wednesday that the Strait of Hormuz should be kept open under all circumstances and Beijing opposes "any extreme acts" at the strategic passageway."Any extreme acts across the Strait of Hormuz, under whatever circumstances they are taken, are against the common interests and aspiration of the people across the world," Wen told a press conference during his official visit to Qatar.The Chinese premier said that cargo transportation through the strait should be protected because it concerns the interests of the whole humanity.Chinese Premier Wen Jiabao attends a press conference in Doha, capital of Qatar, Jan. 18, 2012.China maintains that the Iranian nuclear issue should be resolved through peaceful means, he said, adding that Beijing supports the political process between Iran and the Iran Six, a diplomatic group made up of the United States, China, Russia, Britain, France and Germany.China firmly opposes Iran producing and possessing nuclear weapons and will work with concerned parties to establish a nuclear-free Middle East, Wen said, while stressing that China will not trade its principles for profits.However, just like many other countries, China has also kept "normal" and "justified" trade with Iran, which should be protected, Wen said, adding that should normal trade not be protected, the normal international order would be disturbed."I am not worried about the the normal trade between China and Iran at all," Wen told reporters.Wen arrived in Doha on Wednesday morning after concluding an official visit to the United Arab Emirates.

WASHINGTON, Nov. 14 (Xinhua) -- A novel study in twins found that exposure to trichloroethylene (TCE) -- a hazardous organic contaminant found in soil, groundwater, and air -- is significantly associated with increased risk of Parkinson's disease (PD). Possibility of developing this neurodegenerative disease is also linked to perchloroethylene (PERC) and carbon tetrachloride (CCI4) exposure, according to the study appearing in Annals of Neurology on Monday.The National Institute of Neurological Disorders and Stroke estimates that as many as 500,000 Americans have PD and more than 50,000 new cases are diagnosed annually. While there is much debate regarding cause of PD, studies suggest that genetic and environmental factors likely trigger the disease. Several studies have reported that exposure to solvents may increase risk of PD, but research assessing specific agents is limited.The current epidemiological study, led by Samuel Goldman and Caroline Tanner with The Parkinson's Institute in Sunnyvale, California, investigated exposure to TCE, PERC and CCI4 and risk of developing PD. The team interviewed 99 twin pairs in which one twin had PD and one didn't, inquiring about lifetime occupations and hobbies. Lifetime exposures to six specific solvents previously linked to PD in medical literature -- n-hexane, xylene, toluene, CCI4, TCE and PERC -- were inferred for each job or hobby.The findings are the first to report a significant association between TCE exposure and PD -- a more than six-fold increased risk. Researchers also found that exposure to PERC and CCI4 tended toward significant risk of developing the disease. "Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Goldman in a statement.TCE, PERC and CCI4 have been used extensively worldwide, with TCE noted as a common agent in dry-cleaning solutions, adhesives, paints, and carpet cleaners. Despite the U.S. Food and Drug Administration (FDA) banning the use of TCE as a general anesthetic, skin disinfectant, and coffee decaffeinating agent in 1977, it is still widely used today as a degreasing agent. In the U.S., millions of pounds of TCE are still released into the environment each year and it is the most common organic contaminant found in ground water, detected in up to 30 percent of drinking water supplies in the country.In a release issued on Sept. 28, 2011, the Environmental Protection Agency announced that TCE is carcinogenic to humans.
