LOS ANGELES, April 10 (Xinhua) -- Drinking green tea and practicing Taichi may promote bone health of postmenopausal women and reduce the risk of inflammation, a new study suggests.The study, conducted by researchers at the Laura W. Bush Institute for Women's Health at the Texas Tech University Health Sciences Center, focused on postmenopausal women and investigated the potential for green tea to work synergistically with Taichi in enhancing bone strength of postmenopausal women.Originating as a martial art in China, Taichi is a mind-body exercise that utilizes slow, gentle movements to build strength and flexibility, as well as deep breathing and relaxation, to move qi, or vital energy, throughout the body.The study findings were published Sunday at EurekAlert.org, the website of the American Association for the Advancement of Science (AAAS).Carried out as a double-blind, placebo-controlled, intervention trial (the "holy grail" of scientific studies), this experiment involved 171 postmenopausal women with the average age of 57 who had weak bones but not full-fledged osteoporosis. Subjects were divided into 4 groups -- placebo: starch pill (placebo) and no Taichi; GTP or green tea polyphenols (500 mg/day) and no Taichi; Placebo plus Taichi (starch pill and practising Taichi three times a week); and GTP plus Taichi.The study lasted for 6 months, during which blood and urine samples were collected and muscle strength assessed.The results show that consumption of GTP (at a level equivalent to about four-six cups of steeped green tea daily) and participation in Taichi independently enhanced markers of bone health by three and six months, respectively. A similar effect was found for muscle strength at the 6-month time point. Participants taking Taichi classes also reported significant beneficial effects in quality of life in terms of improving their emotional and mental health.Perhaps most remarkable, however, was the substantial effect that both GTP and Taichi had on biological markers of oxidative stress. Because oxidative stress is a main precursor to inflammation, this finding suggests that green tea and Taichi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well.In the study, the researchers developed an animal model (the ovariectomized, middle-aged female rat), with which they could effectively study the effects of green tea consumption on protection against breakdown of the bone's microarchitecture, according to the AAAS.In humans, this can lead to osteoporosis, a condition common to older women. The researchers say what they have learned from the animal models might also be applicable to postmenopausal women.There is a "favorable effect of modest green tea consumption on bone remodeling in this pre-osteoporotic population," said lead researcher Dr. Chwan-Li (Leslie) Shen, an associate professor at the institute.The researchers plan to soon complete a more long-term study utilizing more technically savvy measures of bone density, according to the AAAS.

BOSTON, the United States, April 9 (Xinhua) -- China's clean energy market offers huge business opportunities, experts said at the Harvard China Forum here Saturday.In a panel discussion on clean energy, experts who have been keeping a close eye on China's renewable sectors evaluated its market size, development level and current challenges."No matter it comes to wind, solar or any other type of clean energy, the market capability in China is enormous," Peter Evans, GE Energy's global strategy and planning director said.Evans said he believed China has the need to develop all kinds of energy in order to meet its ever-growing appetite for energy, especially against the background of high oil price, which just surged to nearly 113 U.S. dollars a barrel.He also said China now has the capital needed to develop clean energy but lacked the technology, although that would not be a problem since "every abroad company related to clean energy wants to go to China and to grab something."Gong Li, chairman of Accenture Greater China, said that for a better development of China's renewable sectors, sustainable policy support is needed.On current challenges, Li said one big problem is the lack of network to turn clean energy into electricity. "Renewable energy such as solar and wind is intermediate energy that needs to be transmitted to the power grid, or else it will be garbage energy," Li said.

CHICAGO, Jan. 21 (Xinhua) -- Chinese President Hu Jintao left Chicago for China on Friday after concluding a state visit to the United States, during which he and his U.S. counterpart Barack Obama agreed to build a China-U.S. cooperative partnership based on mutual respect and mutual benefit.Hu, who began his four-day visit Tuesday, had extensive and in-depth discussions with Obama at the White House on Wednesday on major bilateral, regional and world issues.Chinese President Hu Jintao shakes hands with U.S. President Barack Obama during a bilateral meeting at the White House in Washington, the United States, Jan. 19, 2011.The two sides reached "important agreement on China-U.S. relations and major international and regional issues of shared interests," the Chinese president said when he and Obama met the press following their discussions."We both agree to further push forward the positive, cooperative and comprehensive China-U.S. relationship," Hu said, adding that both sides also pledged to forge "a China-U.S. cooperative partnership based on mutual respect and mutual benefit" for the benefit of the two countries and beyond.

BEIJING, March 24 (Xinhuanet) -- A new study has found that many overweight women and children often underestimate how heavy they are, according to media reports Wednesday.The study, conducted by researchers from Columbia University Medical Center in New York City, surveyed 111 women with the average age of 39 and 111 children aged between 7 and 13.Among the participants, about 66 percent of the women and 39 percent of the kids were overweight or obese.They were shown images of different body silhouettes representing a range of weights, including underweight, normal weight, overweight, obese and extremely obese.The research findings showed that 82 percent of obese women and 43 percent of overweight women underestimated their weight, while only 13 percent of normal weight women did so.As to the children group, about 86 percent overweight or obese kids low-balled their weight.Lead author Dr. Nicole Dumas said, "The implications of this is the overwhelming impact of obesity on children who are growing up in communities where obesity and overweight is the norm rather than the exception."  She added, "Strategies to overcome the obesity epidemic will need to address this barrier to weight loss."
