BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.

BEIJING, April 19 (Xinhuanet) -- Almost one year after the disastrous oil spill, scientists believe that the overall health of the Gulf of Mexico as nearly back to normal.However, the scientists restrain their optimism about nature's resiliency with the glaring blemishes out there. It's been nearly a year since BP's Gulf of Mexico oil spill began last April, triggering one of the world's worst environmental disasters. Nearly 5 million barrels of oil leaked from the ruptured Deepwater Horizon well during the months-long catastrophe.BP said last November that the disaster cost it nearly 40 billion U.S. dollars, according to a Guardian report.According to a BP survey of researchers, over three dozen scientists grade the Gulf's big picture health a 68 on average, using a 1-to-100 scale.That's just a few points below the 71 the same researchers gave last summer when asked what grade they would give the ecosystem before the spill. And it's an improvement from the 65 given back in October after months of the oil spill.

BEIJING, Feb. 1 (Xinhua) -- Senior Chinese official Zhou Yongkang Tuesday called on law enforcement personnel to take more preventive measures against crime and accidents during the Lunar New Year holiday.Zhou, a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, visited community security personnel, a district court, and police patrolling downtown Beijing Tuesday.He also visited a police station that is responsible for keeping public order in the area surrounding the central leadership compound of Zhongnanhai.During his visits, Zhou, who also heads the Commission for Political and Legal Affairs of the CPC Central Committee, said China was seeing the travel peak for the Spring Festival and some regions were suffering icy weather and lingering drought.He asked the police to take effective measures in traffic control and fire-fighting work, and maintain social order during the holiday season.He commended the practice of deploying special police to patrol the surrounding areas of the Tiananmen Square in central Beijing, saying it could deter crime and enable quick responses to emergencies.During his visit to the district court, Zhou warned there were still "many social conflicts."He asked local courts to solve social conflicts more effectively, promote innovative social management and law enforcement in a just and clean manner.The Spring Festival, or Chinese lunar New Year, is the most important festival for Chinese. It falls on Feb. 3 this year.

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.
