BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

BEIJING, Feb. 27 (Xinhua) -- A total of 2.64 billion trips in China were recorded by road or ships during the 40-day Spring Festival transportation season which ended Sunday, the Ministry of Transport said.The figure was 13.6 percent higher than the same period last year, noted ministry spokesman He Jianzhong.To ensure smooth transportation, 840,000 buses were put into use each day during the busy season, as well as 13,089 ships, He said.Statistics on railway transportation are not yet available.However, statistics from the Beijing railway administration showed 20.63 million tourists had left Beijing during the transportation season from Jan. 19 to Feb. 27, up 3.9 percent year on year.The busy Spring Festival transportation season runs for 40 days and is calculated in two phases: 15 days before and 25 days after the Spring Festival.

LOS ANGELES, May 1 (Xinhua) -- Middle-aged adults who sleep too less or too much may be more likely to suffer cognitive decline, a new study suggests.According to the study, less than six hours of sleep each night is considered too little and more than eight hours as too much for middle-aged adults.The study, conducted by researchers at University College London Medical School, was published May 1 in the American medical journal Sleep.The researchers conducted the study in two periods -- the 1997- 1999 period and the 2003-2004 period. The participants were asked how many hours they slept on an average week night, and were asked the same question in 2003-2004 after an average 5.4 years of follow-up.The researchers compared those who reported changes in their sleep patterns with people whose sleep duration stayed the same over the course of the study.In the follow-up, each individual was given a battery of standard tests to assess his or her memory, reasoning, vocabulary, global cognitive status and verbal fluency.The study findings show that women who slept seven hours per night had the highest score for every cognitive measure, followed by those who had six hours of sleep. For men, cognitive function was similar for those who reported sleeping six, seven or eight hours.However, less than six hours of sleep -- or more than eight hours -- were associated with lower scores."Sleep provides the body with its daily need for physiological restitution and recovery," explained Jane Ferrie, a senior research fellow in the department of epidemiology and public health at the school. "While seven hours a night appears to be optimal for the majority of human beings, many people can function perfectly well on regular sleep of less or more hours."However, since most research has focused on the effects of sleep deprivation on biological systems, it is not yet fully understood why seven hours is optimal -- or why long sleeping appears to be detrimental, Ferrie said."Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity," she added.

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.

LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.
