WASHINGTON, Oct. 13 (Xinhua) -- In a trial that included about 35,000 men, those who were randomized to receive daily supplementation with vitamin E had a significantly increased risk of prostate cancer, according to a study published this week in the Journal of the American Medical Association.The study followed more than 35,533 men 50 or older at 427 sites in the United States, Canada and Puerto Rico. The men were divided into four groups who took daily doses of 400 international units of Vitamin E and 200 micrograms of selenium; Vitamin E and a placebo that looked like selenium; selenium and a placebo that looked like Vitamin E; or two placebos. The recommended daily intake of Vitamin E is about 22.4 international units.The researchers from the Cleveland Clinic found that the rate of prostate cancer detection was greater in all treatment groups when compared with placebo but was statistically significant only in the vitamin E alone group -- a 17 percent increased rate of prostate cancer detection. The difference in rates of prostate cancer between vitamin E and placebo became apparent during the participants' third year in the trial. The elevated risk estimate for vitamin E was consistent across both low- and high-grade disease."The observed 17 percent increase in prostate cancer incidence demonstrates the potential for seemingly innocuous yet biologically active substances such as vitamins to cause harm. The lack of benefit from dietary supplementation with vitamin E or other agents with respect to preventing common health conditions and cancers or improving overall survival, and their potential harm, underscore the need for consumers to be skeptical of health claims for unregulated over-the-counter products in the absence of strong evidence of benefit demonstrated in clinical trials," the researchers said.

BEIJING, Jan. 6 (Xinhua) -- Beijing will offer residents 20,000 rental bikes this year to ease the city's notorious traffic jams, according to authorities with the Beijing Municipal Commission of Development and Reform.Five hundred rental kiosks will be set up around the city to offer residents over 20,000 rental bikes, the commission said.Beijing has also proposed creating new bike lanes in some areas, including main streets, historical and cultural conservation areas and some major business districts, from 2011 to 2015, according to the commission.The capital city currently has about 5 million vehicles on its roads, leading to serious traffic congestion that frustrates the city's residents on a daily basis."A lack of bike lanes is the reason why I refuse to ride a bike. Bikes and vehicles are using the same lanes, and that frightens me and makes me feel unsafe," said Beijing resident Song Tao.People often park cars on the city's existing bike lanes, pushing cyclists onto the vehicles' lanes, said Song.To ease traffic congestion, Beijing has made various efforts to encourage people to opt for modes of public transportation.On Dec. 31, Beijing opened three new subway lines, bringing the number of subway lines in Beijing to 15, with a total length of 372 kilometers, said Beijing Metro Spokesman Jia Peng.Beijing will open four more subway lines in 2012, according to information released at a rail transit construction mobilization conference.Amid other measures to ease traffic in 2011, city authorities decided to allow only 240,000 vehicles to be registered annually, slashing the new car registrations by two-thirds from the 2010 level.Meanwhile, vehicles are banned from roads one day each week according to license plate numbers.

HEFEI, Nov. 25 (Xinhua) -- China's leading private automaker, Chery Automobile Co., Ltd., is expected to export a record 170,000 units of vehicles in 2011, marking the highest annual export figure in the company's history, a company manager said Friday.Chery exported 135,556 units of vehicles in the first ten months of this year, up 77.3 percent from a year earlier. This total accounts for 35.3 percent of total passenger vehicle exports of domestic brands, said Feng Ping, deputy general manager of Chery International.The central Anhui province-based carmaker started exporting cars in 2001, when it sold ten cars to Syria, and has since led export sales amongst Chinese automakers.The company exports its products to more than 80 countries and regions, and has established 3 research institutions, a service network of 1,000 dealers and more than 800 service stations overseas.

BEIJING, Oct. 28 (Xinhua) -- The Chinese government will donate one million U.S. dollars to quake-hit Turkey, Foreign Ministry spokeswoman Jiang Yu announced Friday.Jiang said that China has paid great attention to the situation since a 7.2-magnitude earthquake hit eastern Turkey on Sunday.Jiang noted that Premier Wen Jiabao sent a message of condolence to Turkish Prime Minister Recep Tayyip Erdogan immediately after the quake.The Red Cross Society of China has also donated 50,000 U.S. dollars, and China will continue to offer emergency relief aid to Turkey, she added.According to the Turkish government, as of Friday morning, 570 people were dead and 2,250 injured after the powerful earthquake struck the province of Van in eastern Turkey on Sunday.

BEIJING, Jan. 8 (Xinhua) -- China canceled over one-third of all official ceremonies, seminars and forums last year in a bid to avoid extravagance or corruption in the use of public resources.Some 2,549 such activities proposed by governments or public institutions, or 37.7 percent of the total applications, which were deemed "ceremonial" and "unnecessary," were cut, saving 1.22 billion yuan (about 193.39 million U.S. dollars), said an official statement released Sunday.The statement was issued by the State Council's Office for Rectifying Malpractices, a ministry-level inter-agency supervisory body dedicated to eliminating administrative irregularities and abuse of power in government agencies, public institutions and major service sectors.Last year's inspections focused on activities co-funded by ministries and local governments, the statement said.The Chinese government agreed with the public that the soaring number of official celebrations, seminars and forums would cost plenty of money and manpower and exacerbate corrupt behaviors.In March, the State Council, or China's Cabinet, ordered 98 ministries and ministry-level government organs to make public their budgets and expenditures on official overseas visits, public vehicles and official receptions -- the "three public consumptions" that had triggered widespread public concern.Premier Wen Jiabao also repeatedly urged the country's government agencies to reduce administrative expenses, including cutting the number of meetings and documents printed.Official figures indicate that the country's crackdown on various forms of extravagant spending by officials saved the country 5.7 billion yuan in 2010.A blue book on China's conferences published in November estimated that the total output of the country's conference industry had reached nearly 1 trillion yuan. Companies made up half of this total, while a considerable portion came from the government and public institutions compared to other social organizations.
