WASHINGTON, July 5 (Xinhua) -- Adhering to a healthy lifestyle, including not smoking, exercising regularly, having a low body weight and eating a healthy diet, appears to lower the risk of sudden cardiac death (SCD) in women, according to a study to be published Wednesday in the Journal of the American Medical Association."Sudden cardiac death (defined as death occurring within one hour after symptom onset without evidence of circulatory collapse) accounts for more than half of all cardiac deaths, with an incidence of approximately 250,000 to 310,000 cases annually in the United States," the authors write as background information in the study.Using data collected as part of the Nurses' Health Study, Stephanie Chiuve, of Brigham and Women's Hospital and Harvard Medical School, and colleagues examined the association between a healthy lifestyle and risk of SCD.A total of 81,722 women who participated in the Nurses' Health Study from June 1984 to June 2010 were included in the new study, and lifestyle factors were assessed via questionnaires every two to four years. A low-risk lifestyle was defined as not smoking, having a body mass index (BMI) of less than 25, exercise duration of 30 minutes/day or longer, and consuming a diet closely related to a Mediterranean-style diet (emphasizes high intake of vegetables, fruits, nuts, legumes, whole grains and fish, with moderate alcohol intake).During the 26 years of follow-up, there were 321 cases of SCD among women (average age 72 years at the time of the SCD event) in the study. All four low-risk factors were significantly and independently associated with a lower risk of SCD. Not smoking, exercising and eating a healthy diet each were inversely associated with risk of SCD. BMI also was associated with the risk of SCD, with women having a BMI between 21 and 24.9 at lowest risk.Women at low risk for all four lifestyle factors had a 92 percent lower risk of SCD when compared with women at low risk for none of the four lifestyle factors."In this cohort of female nurses, adherence to an overall healthy lifestyle was associated with a lower risk of SCD and may be an effective strategy for the prevention of SCD," the authors write.

BEIJING, Sep. 13 (Xinhuanet) --Experts have called for a national drug-control system after a nationwide deficit of a life-saving drug, which has lasted at least three months.Doctors at a Beijing hospital said some specialized hospitals, which perform hundreds of cardiac operations every month, have been paralyzed by their lack of protamine sulfate, which is commonly administered after heart surgery to reverse the anticoagulant effects of heparin.The earliest report of a shortage was in Hubei province on July 21. This was followed by reports of shortages in Guangdong, Shandong and Liaoning provinces.The Shandong newspaper, Qilu Evening News, quoted a regional sales manager, surnamed Zhuang, as saying the province had been allocated 150 doses of protamine sulfate after Shanghai No 1 Biochemical and Pharmaceutical Co Ltd recently resumed production of the drug."But its monthly use here is usually 10,000 doses," he said.The Ministry of Health has denied it is responsible for supplies of the drug and passed the buck to the State Food and Drug Administration, claiming the latter is responsible for the supervision of medicines.Shen Chen, head of the publicity office of the State Food and Drug Administration, said he was unaware of the shortage, but said the administration is responsible for the quality of medicines, not the supply."Development and reform authorities oversee the medicines' prices, while the industrial and commercial authorities oversee the storage. The food and drug departments only cover the approval and quality of medicines."Industry insiders said one of the reasons for the shortage was the low profit margin, which discourages companies from mass producing the drug."Some companies can't earn enough to recover their costs, therefore it is almost impossible to maintain their enthusiasm for continuing production," said Lu Guoping, secretary-general of the Shanghai Pharmaceutical Trade Association.Lu said the government should issue policies to prevent future shortages of such medicines to avoid possible nationwide public health incidents.Yi Shenghua, a lawyer at Beijing Yingke Law Firm, said the country should have a unified system to guarantee the normal supply of medicines that are widely used and drug manufacturers should fulfill their responsibilities to society, even though there is no law stipulating they should produce specific medicines.He came up with two ways to deal with the problem of companies only producing profitable drugs."The government can order businesses to manufacture a certain amount of cheap medicines. Or it can offer financial assistance to subsidize cheap, but life-saving medicines."

BEIJING, July 26 (Xinhuanet) -- Hong Kong scientists announced that they had determined the idea of time travel is impossible by proving nothing can travel faster than the speed of light.The finding is contained in a study done by a research team from Hong Kong University of Science and Technology. The study was published Monday in a scientific journal "Physical Review Letters" in the United States."The study, which showed that single photons also obey the speed limit c, confirms Einstein's causality, that is, an effect cannot occur before its cause," the university said on its website."By showing that single photons cannot travel faster than the speed of light, our results bring a closure to the debate on the true speed of information carried by a single photon." said Professor Du Shengwang, who led the study.The possibility of time travel was raised 10 years ago when scientists discovered the optical pulses in some specific medium might propagate information in a faster-than-light speed."Our findings will also likely have potential applications by giving scientists a better picture on the transmission of quantum information." Du said.

COPENHAGEN, May 30 (Xinhua) -- The number of confirmed E. coli cases has risen to 14 in Denmark, with at least 26 others suspected of having the intestinal infection, the National Serum Institute said Monday.Seven of the confirmed cases show symptoms of kidney failure which marks an advanced stage of the sickness, the institute said."Almost all of the 14 infected people have been in northern Germany recently except just one. There is a 24-year-old man from Jutland. He has not even been to Germany, so he does not quite fit with the rest of the pattern," said Kaare Moelbak, chief physician at the institute. "We do not know yet how he has been so unlucky to get this infection but we assume that it has been a person-to-person transmission, or that he has eaten infected vegetables," he added.Denmark's Veterinary and Food Administration (DVFA) had advised Danish consumers not to eat raw tomato, lettuce and cucumber from Germany, and cucumber from Spain.It is now checking Danish cucumbers for traces of E. coli, with results expected on Tuesday.
