BEIJING, Oct. 13 (Xinhuanet) -- A new study finds that ginger may decrease the risk of colon cancer through diminishing the inflammation in the gut, according to media reports Thursday.Prior researches have found that chronicle inflammation in the gut is related to colon cancer, suggesting easing inflammation in intestines might reduce the risk of the cancer, said Suzanna M. Zick, lead author of the study published online in Cancer Prevention Research. Zick, also a naturopathic physician and research associate professor at University of Michigan Medical Center, and her colleagues, assigned 30 volunteers to take pills containing two grams of either placebo powder or ginger root extract, equivalent to about two tablespoons of ground-up raw ginger root.And they recorded the inflammations in the participants' intestines before and after the test period.The researchers found that participants taking ginger pills had 28 percent less inflammation in their intestines after the test. But no difference was found in those who took placebo.The findings are promising, but the researchers are not yet recommending people start taking more ginger at meal times. The study only involved 30 participants, so it is just a preliminary study. Zick said they hope to launch a larger study in the future, according to USA Today.

BEIJING, Jan. 24 (Xinhua) -- China's meteorological authority said Tuesday that the country's northern regions will continue to have sunny weather for the coming 24 hours, while the south will see subdued rain and snow.Temperatures in most parts of the country are expected to rebound slightly, the National Meteorological Center said in a statement on its website.But the lowest temperatures in the areas south of the Yangtze River will remain around zero degree Celsius, the center said.Meanwhile, rain and snow will subdue in most parts of the southern regions over the next three days, although freezing rain is forecast to hit Guizhou and Hunan provinces, according to the statement.

HONOLULU, United States, Nov. 12 (Xinhua) -- Chinese President Hu Jintao met his U.S. counterpart Barack Obama in Honolulu, Hawaii, Saturday to discuss Sino-U.S. ties and major world and regional issues.Hu and Obama were meeting before the Economic Leaders Meeting of the Asia-Pacific Economic Cooperation (APEC) scheduled for Saturday and Sunday in Hawaii.In a meeting with U.S. Secretary of State Hillary Clinton on Thursday in Honolulu, Chinese Foreign Minister Yang Jiechi said the Hu-Obama meeting has great significance for the steady development of China-U.S. relations.He noted that under the current situation, China is ready to make concerted efforts with the United States to deepen understanding, enhance mutual trust and better carry out the consensus reached by the two countries' leaders, so as to build a cooperative partnership based on mutual respect and mutual benefit.Clinton said President Obama looked forward to his meeting with President Hu.The U.S. side values its cooperative partnership with China, which is not only in the interests of both sides, but also holds great importance to the world at large, she said.Earlier this month, Hu and Obama met in Cannes, France, on the sidelines of a summit of the Group of Twenty (G20) and exchanged views on bilateral ties and the G20 summit.

WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.

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.
