BEIJING, Oct. 11 (Xinhuanet) -- Debates in the medical field developed on Monday as a U.S. government panel recommended that men of all ages should stop getting prostate cancer blood screenings.The United States Preventive Services examined all the evidence and found little if any reduction in deaths from routine P.S.A. screening and suggested that the test does more harm than good to healthy men.The P.S.A. test for prostate cancer, a blood test to screen for a protein that may indicate cancer, has become widely used because it can help detect tiny tumors at a very early sta ge, when they are theoretically most treatable.Unfortunately, according to the task force, the vast majority of the results are false-positives: the men don’t actually have cancer. And most of those found to have cancerous cells would not suffer ill effects because their cancer is so slow-growing that it would not cut short their lives. Those with faster-growing cancers may also not be helped if the cancer is extremely aggressive.After the recommendation came out last week, many prostate cancer specialists have been pushing back.Urologist Dr. Mark DeGuenther said this recommendation is more about saving money than saving lives. He said death rates from prostate cancer have dropped 40 percent since men began getting screened at age 40 and he says it will save taxpayers and patients more money in the long run to diagnose and treat cancers earlier rather than wait and have to provide expensive care for advanced stage cancers."We all agree that we've got to do a better job of figuring out who would benefit from P.S.A. screening," said Dr. Scott Eggener, a prostate cancer specialist at the University of Chicago. "But a blanket statement of just doing away with it altogether ... seems over-aggressive and irresponsible."Dr. Deepak Kapoor, chairman and chief executive of Integrated Medical Professionals, which includes the nation's largest urology practice, said "We will not allow patients to die, which is what will happen if this recommendation is accepted."That task force's recommendation isn't final - it's a draft open for public debate. And obviously the debate is already under way.

BEIJING, Oct. 11 (Xinhuanet) -- For women, chocolate consumption needs to be high, which can lower stroke risk, researchers from the Karolinska Institute, Sweden, reported in the Journal of the American College of Cardiology. The consumption of chocolate has been demonstrated to reduce diastolic and systolic blood pressure in randomized, short-term trials. Chocolate has also been shown to improve endothelial and platelet function, and to improve insulin resistance.Susanna Larsson Ph.D. and the team conducted the research on the Swedish Mammography Cohort's 33,372 adult females aged from 49 to 83 years without history of stroke, coronary heart disease, stroke, or diabetes.They found those who ate at least two chocolate bars each week appeared to have a 20 percent lower risk of stroke, compared to those of the same age and weight who rarely or never ate chocolate. But, they found, it was only those in the highest quartile of chocolate consumption who had a significant drop in stroke risk.The researchers explained that cocoa has flavonoids - powerful antioxidants that can suppress LDL, low-density lipoprotein, that can cause stroke and other cardiovascular diseases.

BEIJING, Jan. 14 (Xinhua) -- A Spring Festival gala was held at the Great Hall of the People Saturday to entertain the country's military officers, soldiers and civilians.Representatives of officers and soldiers in the military units and armed police forces in Beijing as well as some Beijing residents attended the gala.President Hu Jintao and other top Chinese leaders including Wu Bangguo, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang were also present at the gala.Hu expressed greetings to the audience and extended his good wishes for them, ahead of the traditional Spring Festival, or the Chinese Lunar New Year, which falls on Jan. 23 this year.

SAN FRANCISCO, Jan. 13 (Xinhua) -- Google seems to get no blessings for a good start for its New Year resolutions as the Internet search giant got an earful of complaints about its new social search service and felt mortified by a customer-poaching scandal in its Kenyan division.On Tuesday, Google announced "search plus your world" to deliver personalized search results by embedding its social service Google+ to its search engine.Although Google called it as "a beautiful journey begins," competitors and industry watchers said it was "a bad day for the Internet." They accused the company of using its dominant search engine to promote its own social networking site by giving Google+ pages and profiles an artificially prominent position in search results.The search giant first had a public bickering with Twitter which issued a statement on Tuesday saying that "As we've seen time and time again, news breaks first on Twitter. We're concerned that as a result of Google's changes, finding this information will be much harder for everyone."Google on Wednesday made a statement on its official Google+ page, saying that "We're a bit surprised by Twitter's comments because they chose not to renew their agreement with us last summer." The agreement, in which Twitter gave Google access to public tweets, expired last July and was not renewed.Twitter fired back by demonstrating the inefficiency of the new Google search feature. Twitter general counsel Alex Macgillivray tweeted a page of Google search results for the search term "@WWE" which did not include World Wrestling Entertainment's Twitter page, but Google+ page.Macgillivray noted that with 792,642 followers on Twitter compared with 24,900 followers on Google+, WWE's Twitter page is a more relevant social source than Google page and should be presented in Google's search results.Facebook, Google+'s major rival, has been remaining silent this week publicly while its employees criticized Google's moves in public status updates. Several prominent Facebook engineers and directors shared a tech blog about switching default search engine to Microsoft's Bing after "Google broke itself."Facebook has been working with Microsoft to allow Bing to reveal more personalized content.Industry watchers are also crying foul at the privacy and antitrust concerns raised by the new search feature. Search Engine Land, a tech blog closely following Google's news, posted several examples of how Google favors its own social networking service.Industry watchdog Electronic Privacy Information Center told the Los Angeles Times that the group is considering filing a complaint with the U.S. Federal Trade Commission (FTC). The organization once made the complaint that resulted in Google's settlement with the FTC last year that requires the Mountain View, California-based company to submit to external audits of their privacy practices every other year.On Friday, a Kenyan business directory startup Mocality said that Getting Kenyan Businesses Online, a Google-backed initiative to give small businesses free websites for one year, routinely accessed Mocality's database to obtain sales leads.The Search giant's Kenyan division called Mocality customers to pitch Google's alternative service, claiming they have had a partnership with Mocality. Mocality CEO Stefan Magdalinski said there is no such partnership.In a statement sent to the U.S. media, Google said it is " mortified" to learn that a team representing Google improperly used Mocality's data and misrepresented their relationship with the Kenyan company, noting that it "unreservedly apologized to Mocality" and is still investigating the issue.On Monday, BBC revealed that Google admitted profiting from advertisements of illegal websites selling drugs, fake passports and unauthorized tickets for the 2012 Olympics.The ads had been removed by Google after they were brought to the company's attention, but the search giant told BBC that the company "keeps any money it might make from companies advertising illegal services before such ads are removed."Meanwhile, on Thursday, Microsoft announced it has signed a patent licensing agreement with LG Electronics on the manufacturer 's devices running Google Android platform, leaving Motorola Mobility the only major Android-powered device maker that refuses to strike a deal with Microsoft.After the announcement, Microsoft's directors have been taking to Twitter to taunt Google as the two companies had a history of public back-and-forth. But so far, it appeared that Google didn't have time to needle back.

OTTAWA, Oct. 3 (Xinhua) -- Many friends and colleagues of Canadian scientist Ralph Steinman reacted with shock when they learned on Monday that Steinman won the Nobel Prize for Medicine and Physiology three days after he died.Since 1974, Nobel Prizes are no longer awarded posthumously, but the Nobel Prize committee said that it had made its choice before Steinman's death.Many of Steinman's friends and colleagues said that they learned of Steinman's death at the same time that they learned of his Nobel Prize, which was awarded for a discovery Steinman made in 1973.Steinman, 68, discovered dendritic cells, which help regulate adaptive immunity, which purges invading microorganisms from the body. Dendritic cells activate T cells, which "remember" the DNA sequence of invading organisms and protect the body from later infections from the same disease."Their work has opened up new avenues for the development of prevention and therapy against infections, cancer and inflammatory disease," the citation said.Monday, the Nobel Committee defended its decision to award the prize to Steinman. "The decision to award the Nobel Prize to Ralph Steinman was made in good faith, based on the assumption that the Nobel Laureate was alive," the foundation said in a statement."The Nobel Foundation thus believes that what has occurred is more reminiscent of the example in the statutes concerning a person who has been named as a Nobel Laureate and has died before the actual Nobel Prize Award Ceremony."It is still unclear who will pick up Steinman's prize at the award ceremony later this year.Steinman, a cell biologist at Rockefeller University in New York City, died of pancreatic cancer on Friday. For more than four years, he had used his own immune therapy discoveries to extend his life."The news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago," Rockefeller University President Marc Tessier-Lavigne said in a statement."We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize," Steinman's daughter, Alexis, said in the statement. "He devoted his life to his work and his family, and he would be truly honored."Steinman's heirs will share the 1.5-million U.S. dollar prize with American genetics professor Bruce Beutler and French scientist Jules Hoffmann.Dr. Beutler is professor of genetics and immunology at The Scripps Research Institute in La Jolla, California. Dr. Hoffmann headed a research laboratory in Strasbourg, France, between 1974 and 2009 and served as president of the French National Academy of Sciences between 2007 and 2008."Ralph worked right up until last week," said Michel Nussenzweig, a collaborator of Steinman's at Rockefeller University. "His dream was to use his discovery to cure cancer and infectious diseases like HIV and tuberculosis. It's a dream that's pretty close."Steinman was born in 1943 in Montreal, Canada's second largest city, and studied chemistry and biology at McGill University in his hometown before receiving an MD from Harvard Medical School in Boston in 1968. He joined Rockefeller University in 1970 as a postdoctoral fellow."He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design," the university said in a statement.In a statement, Canadian Prime Minister Stephen Harper lauded the three winners of the Nobel for medicine and called the award " a fitting final tribute" to Steinman's life's work."Dr. Steinman shall be honored for all time with this achievement," Harper said. "Canadians will mourn his loss."
