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) -- Vice President Xi Jinping has said China is willing to cooperate with Russia on strategic security matters, and that the two nations should work more closely on bilateral and multilateral issues.Xi made the remarks on Thursday in his meeting with Russian Security Council Secretary Nikolai Patrushev, according to a press release issued by the Chinese Foreign Ministry on Friday.China will work more closely with Russia in order to strengthen communication and coordination on regional and international issues, Xi said.Patrushev is in Beijing to co-chair the sixth round of China-Russia strategic security talks with Chinese State Councilor Dai Bingguo.Chinese Vice President Xi Jinping (R) shakes hands with Russian Security Council Secretary Nikolai Patrushev (L) in Beijing, capital of China on Oct. 20, 2011.Xi spoke highly of the contribution made by the China-Russia strategic security talks in boosting bilateral political mutual trust and strategic coordination, calling on the two sides to step up strategic coordination in a bid to better safeguard the common interests of the two nations and promote peace and stability in the world.Citing the significant and profound transition of the international situation, Xi said the two nations face opportunities as well as challenges in maintaining a strategically secure environment for their own development.On bilateral relations, Xi said China always prioritizes its relations with Russia in the country's foreign policy. He expressed China's willingness to make concerted efforts with Russia to push forward bilateral cooperation in the political, economic, energy, science and technology fields.Russia was highly satisfied with the current development of the bilateral ties, Patrushev said, proposing the two sides should strengthen strategic communication, expand mutual trust and cement coordination in multilateral organizations such as the United Nations and the Shanghai Cooperation Organization.China-Russia strategic security talks were initiated by leaders of the two countries in 2005.

NEW DELHI, Jan. 9 (Xinhua) -- Chinese ambassador to India Zhang Yan Monday proposed that China and India make more efforts to develop economic ties.At a meeting on China-India relations attended by Indian National Security Advisor S. Menon, the ambassador said the Chinese side is fully aware of the necessity to narrow the trade gap between the two sides in order to ensure the sustainability of bilateral trade cooperation."China will take measures to increase the import of Indian products which have market demand in China. But our cooperation should not be limited in trade only," said the ambassador.He suggested that China and India should diversify their trade structure, expand the scope and items, and increase the technical content and added value to the products, while expanding into financial, service and investment sectors.The envoy said China and India should initiate policy dialogue and coordinate their economic development strategy in order to ensure steady growth of respective economy, encourage mutual investments, consider the free trade agreement or regional trade arrangement, and increase tourism cooperation.Zhang said that as an encouraging sign of economic ties, the bilateral trade volume is set to hit 70 billion U.S. dollars in 2011, an over 20 percent increase over the previous years, while China set up its first branch of the Industrial and Commercial Bank of China in Mumbai last year.

BEIJING, Oct. 28 (Xinhuanet) -- Taking aspirin everyday may lower the risk of developing colon cancer for people with the cancer-causing genes, researchers found.The finding was published on Friday in the British medical journal "Lancet".The researchers followed 508 patients with Lynch syndrome, an inherited disorder which increases the risk of developing colon and other cancers.These patients were divided into two groups: members in one group took 600 mg aspirins everyday; another group took only the dummy pills.After 4 years, 10 colon cancer cases were reported among 258 patients who took daily aspirins for at least two years, comparing with 23 cases among 250 patients on dummy pills."This is good news for a very specific population," said Asad Umar, a cancer prevention expert at the U.S. National Cancer Institute.However, the finding doesn't apply to the general public, suggested the lead author of the study John Burn, a geneticist at Newcastle University in England.Only those who are at risk of such diseases should consider taking aspirin regularly, such as people having a family history of colon cancer, he added.

BEIJING, Nov. 20 (Xinhua) -- China on Sunday morning put two satellites into orbit from the Jiuquan Satellite Launch Center in northwest China's Gansu Province.The satellites, Chuangxin 1-03 and Shiyan Satellite 4 were launched on a Long March 2D carrier rocket at 8:15 a.m. Beijing Time, said a Xinhua photographer, who witnessed the whole process.The Chuangxin 1-03, developed by the Chinese Academy of Sciences, will be used to collect and relay water conservancy, hydrological and meteorological data and data for power supply and disaster relief from monitoring stations.The Shiyan Satellite 4 will be used for experiments on space technologies and environment probe. Developed by the Chinese Research Institute of Space Technology, it is the country's fourth technology experiment satellite.The launch was the 151th of China's Long March series of rockets. The Long March-2D is one of the derivations of Long March-2.China started development of modern carrier rockets in 1956, and Long March rockets have become the main carriers for China's satellite launching.
