BEIJING, April 12 (Xinhuanet) -- The elderly have a difficult time with multi-tasking as a study suggests that older brains behave differently when it comes to switching between two tasks, according to media reports on Tuesday.Researchers used functional magnetic resonance imaging (FMRI) to analyze brain activity in 20 people over age 60 by asking them to contemplate outdoor photos shown briefly. Then the elderly were presented with the picture of a face and asked to determine its gender and age, before being asked to recall details from the original scene they viewed.Researchers then compared their results to a similar experiment with 20 younger adults and found the brains of older subjects were less capable of disengaging from the interruption and reestablishing the neural connections necessary to switch back to focusing on the original memory."Unlike younger individuals, older adults failed to both disengage from the interruption and re-establish functional connections associated with the disrupted memory network," write Wesley C. Clapp of the University of California, San Francisco, and colleagues in the Proceedings of the National Academy of Sciences.The study, published in the online edition of the journal Proceedings of the National Academy of Sciences, sheds new lights into a growing body of studies showing that one's ability to move from one task to another in quick succession becomes more difficult with age.

NANJING, April 23 (Xinhua) -- At a time when almost every commodity in China is getting more expensive, the dwindling cost of medicine is a rarity.Zhang Jinkui, a hypertension patient, buys medicines from the community health center of his neighborhood in Changzhou, a city in east China's coastal Jiangsu Province.His prescription list includes Aspirin Enteric-coated tablets, down to 1.4 yuan from 4.7 yuan (0.7 U.S. dollars) per unit, and Fosinopril Sodium Tablets, down to 41.39 yuan from 51.6 yuan per unit.Both drugs are found on the essential drug list unveiled in 2009. The list names the 307 most common western and traditional Chinese medicines, which are heavily subsidized so hospitals can sell them at cost price.A consumer buys medicines with the help of a retailer at a pharmacy in Lianyungang, east China's Jiangsu Province, March 28, 2011.All essential medicines are listed by their generic names, and drug producers compete to supply essential medicines through public procurement.Due to a long history of low government funding for state-run hospitals, which often covers only 10 percent of the hospitals' operating costs, doctors have generated income for hospitals by aggressively prescribing expensive, and sometimes unnecessary, medicines and treatments.The essential medicine system and the reform of publicly funded hospitals, two pillars of China's health reform, are designed to address high medical costs and low accessibility of medical services.In April 2009, China kicked off health reforms aimed at correcting these long-standing problems facing China's health system and easing public grievances.Two years later, the essential medicine system has reduced drug prices, but still fails to please hospitals, patients and drug producers.The system requires government-funded grassroots health clinics, including urban community health centers and rural clinics, to prescribe only essential medicines and to sell these medicines at cost price, rather than with the previous 15 percent mark-up.Such policies have brought hard times to grassroots health clinics, especially in cash-strapped areas.Song Wenzhi, a public health professor at Peking University, said "Grassroots health clinics, without the expertise to perform operations and other treatments, rely heavily on selling drug," adding that these hospitals have found themselves scraping by due to the zero percent mark-up policy.Wang Zhiying, Vice Director of the People's Hospital of Anxiang County in the city of Changde, Hunan Province, said four grassroots hospitals in Changde tested the essential medicine system as pilot projects, but the zero percent mark-up policy took away 60 to 70 percent of the hospitals' revenue.Wang was quoted by "Health News," a newspaper run by China's Ministry of Health, as saying that, due to financial difficulties, the county government had not yet channeled the 8 million yuan (1.2 million U.S.dollars) in support funds into the hospitals' accounts, resulting in the resignations of many doctors.The essential medicine system covers 60 percent of government-funded grassroots hospitals and drug prices have fallen by an average of 30 percent, said Sun Zhigang, Director of the Health Reform Office under the State Council, or China's Cabinet.According to the health reform plan for 2011, the essential medicine system will cover all government-sponsored health institutions at the grassroots level by the end of the year and drugs will be sold there at a zero percent mark-up.Song Wenzhi said the key will be the commitment of local governments to health reform and their financial input. This way, essential medicines can benefit the public without bankrupting grassroots health institutions."That would be a great sum of money." said Song, citing his own studies. "There are roughly 5,000 government-funded hospitals in China. One third of them make profits, one third barely break even, and still one third rely heavily on government subsidies."To maintain the poorest hospitals, central and local level governments would need to invest 15 billion yuan (2.3 billion U.S. dollars) each year, according to Song's estimate.

BEIJING, May 10 (Xinhuanet) -- Researchers from California, Unated States, found that sexual orientation could play a role in cancer and more gay men are reported being cancer survivors than straight men, according to findings in the journal Cancer online Monday.The researchers found that gay men are 1.9 times more likely than straight men to report having had cancer. They also found that lesbian and bisexual women are more than twice as likely as heterosexual women to report fair or poor health after having cancer.Researchers looked at three years of responses to the California Health Interview survey, which included more than 120,000 adults living in the state.Among other health-related questions, participants were asked if they had ever been diagnosed with cancer and whether they identified as gay, lesbian, bisexual, or straight.Out of 51,000 men, about 3,700 said they had been diagnosed with cancer as an adult. While over 8 percent of gay men reported a history of cancer, that figure was only 5 percent in straight men, a disparity that could not be attributed to differences in race, age or income.About 7,300 out of 71,000 women in the study had been diagnosed with cancer, but overall cancer rates did not differ among lesbian, bisexual, and straight women.Ulrike Boehmer, the study's lead author from the Boston University School of Public Health, said higher rates of human immunodeficiency virus (HIV) may be related to the increased risk of cancer in gay men.However, the findings do not necessarily mean that being gay, lesbian or bisexual increases risk of cancer, said the researcher.

BEIJING，March 11 (Xinhuanet) --A poor diet during pregnancy may result in health problems such as diabetes for the offspring in later life, according media reports Friday quotting a new research.Based on a study of rats, researchers from the University of Cambridge altered the protein content of the mother's diet during pregnancy as they found that rats were more vulnerable to the effects of diseases if their mothers were malnourished while they were pregnant.Further, the study also showed that an imbalanced diet in the expectant mother can compromise the long-term functioning of a gene in the child. And the gene, named Hnf4a, is believed to play a major role in the development of the pancreas and in the production of insulin.The researchers held similar mechanisms seen in the rat study could occur in humans, and that the effects might be felt by more than just the immediate offspring."What is most exciting about these findings is that we are now starting to really understand how nutrition during the first nine months of life spent in the womb shape our long term health by influencing how the cells in our body age," said Susan Ozanne, senior author of the paper and senior fellow from the Institute of Metabolic Science at the University of Cambridge.And Jeremy Pearson, associate medical director at the British Heart Foundation, said: "The reasons why are not well understood, but this study in rats adds to the evidence that a mother's diet may sometimes alter the control of certain genes in her unborn child.""It's no reason for expectant mothers to be unduly worried. This research doesn't change our advice that pregnant women should try to eat a healthy, balanced diet," he added.
