LOS ANGELES, April 6 (Xinhua) -- Freeze-dried strawberries may play a role in the prevention of esophageal cancer, a new study suggests."Strawberries may be an alternative or work together with other chemopreventive drugs for the prevention of esophageal cancer," said lead researcher Tong Chen, M.D., Ph.D., assistant professor, division of medical oncology, department of internal medicine at the Ohio State University.Study findings were presented at the ongoing 102nd annual meeting of the American Association for Cancer Research (AACR) in Orlando, Florida, according to the American Association for the Advancement of Science (AAAS) on Wednesday."We concluded from this study that six months of eating strawberries is safe and easy to consume. In addition, our preliminary data suggests that strawberries can decrease histological grade of precancerous lesions and reduce cancer- related molecular events," said Chen, who is also a member of the Molecular Carcinogenesis and Chemoprevention Program in the Ohio State University Comprehensive Cancer Center.The study involved a group of participants who consumed 60 grams of freeze-dried strawberries daily for six months and completed a dietary diary chronicling their strawberry consumption.The researchers obtained biopsy specimens before and after strawberry consumption. The results showed that 29 out of 36 participants experienced a decrease in histological grade of the precancerous lesions during the study.Using freeze-dried strawberries was important because by removing the water from the berries, they concentrated the preventive substances by nearly 10-fold, Chen said.Esophageal cancer is the third most common gastrointestinal cancer and the sixth most frequent cause of cancer death in the world, she noted.Chen and her team are studying esophageal squamous cell carcinoma (SCC) which makes up 95 percent of cases of esophageal cancer worldwide. China, where this study took place, has the highest incidence of esophageal SCC, according to the AAAS.In a previous study, Chen and colleagues found that freeze- dried strawberries significantly inhibited tumor development in the esophagus of rats. Based on these results, they embarked on a Phase Ib trial that included participants with esophageal precancerous lesions who were at high risk for esophageal cancer."Our study is important because it shows that strawberries may slow the progression of precancerous lesion in the esophagus," Chen said.But she said they need to test this in randomized placebo- controlled trials in the future.

BEIJING, April 19 (Xinhuanet) -- The case in the Hollywood blockbuster "The Social Network" continues in real life.Twins Cameron and Tyler Winklevoss on Monday filed another appeal against their Harvard classmate and Facebook founder Mark Zuckerberg.The Winklevosses claim that the case needs to be reviewed by a special 11-judge panel in the latest appeal, after a three-judge panel of the 9th U.S. Circuit Court of Appeals ruled against the brothers last week.The twins initially claimed that Zuckerberg had stolen their idea for the website but agreed to drop their lawsuit in 2008 in exchange for 20 million dollars in cash and stock in the company.But later they discovered the stock was worth less than claimed at the time and sought to have the deal voided, the brothers said.

BEIJING, Jan. 25 (Xinhua) -- The central parity rate of yuan, the Chinese currency, Tuesday gained 2 points to 6.5881 against the U.S. dollar, according to the China Foreign Exchange Trading System.China's central bank announced in June 2010 it would further reform the exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market each business day.

BEIJING, Jan. 19 (Xinhua) -- China's central government on Wednesday called on local authorities to step up efforts to ensure a stable market supply of daily necessities, such as food and clothing, as freezing weather continues to plague south and southwest China.The Ministry of Commerce required local government departments to guide companies to increase supplies such as rice, edible oil, meat and vegetables.It also required local departments to closely watch market changes and release reserves of commodities when necessary, said a statement on its website.The statement said the government of southwest China's Chongqing Municipality has urged local supermarkets to maintain the prices of 10 types of vegetables that are affordable to the public, while authorities in the rain and snow-battered Guizhou and Hunan provinces guided logistics companies and wholesales markets to take measures to insure supplies.The Ministry of Agriculture on Wednesday also ordered local departments to expand areas for growing vegetables when conditions allow, as agricultural experts were also sent to fields to help farmers save their crops.The country's meteorological authority forecast Wednesday that over the next three days, heavy snow and icy rain would continue in provinces and municipalities including Guizhou, Hubei, Hunan, Jiangxi, and Chongqing.

BEIJING, Feb. 8 (Xinhua) -- Forty people died in more than 118,000 cases of fire reported across China from February 2 to February 8, as Chinese revelers celebrated the Lunar New Year holiday with fireworks, according to a statement released Tuesday by the country's Ministry of Public Security.The number of cases jumped from the 7,480 fires reported during last year's Spring Festival holiday, which caused losses worth 28.5 million yuan. The incidents also injured 37 people and caused more than 56 million yuan (8.5 million U.S. dollars) in damages, which is almost double the figure from last year.However, this year's losses did not include a case in northeastern Liaoning Province where a five-star hotel in the city of Shenyang was set ablaze by fireworks on February 3.The fire, which caused no casualties, is possibly the country's largest fireworks accident during this year's Spring Festival celebrations.According to the statement, some 260,000 police and fire fighters across the country were mobilized for 24,800 fire control missions.The personnel rescued more than 1,600 people and evacuated tens of thousands. Fire departments have been strengthening monitoring of high-rise buildings, shopping malls, markets, construction sites and other crowded or vulnerable locations.Also, a total of 173 companies were suspended from operating for failing to meet fire prevention and control standards, according to the ministry.
