BEIJING, Aug. 31 (Xinhuanet) – The pressure of modern society is taking a toll on sexual satisfaction, experts say following the release of an online survey.About 34 percent of people polled in the survey said that they are unsatisfied with their sex lives, with 6.5 percent "very unsatisfied".Another 32 percent condemned their sex lives as "just so-so".The survey interviewed more than 3,000 people, aged between 15 and 55, with men accounting for 74 percent of the interviewees.It was conducted by the China Population Communication Center and the Shanghai Academy of Social Sciences from May 1 to June 20. The survey did not give a margin of error.Only 23 percent of respondents said that they are "satisfied" with their sex lives, with 3.6 percent "very satisfied", according to the survey.But women seem to have a higher rate of satisfaction than men, with only 26 percent saying they are unsatisfied. The rate for men is 42 percent.The rate of sexual satisfaction among Chinese people is below the global average of 44 percent, according to an earlier survey by Durex. The 2007 Durex Global Sexual Wellbeing Survey questioned more than 26,000 people in 26 countries about all aspects of their sex lives - including satisfaction levels.Jiang Hui, president-elect of the Chinese Society of Andrology, attributed the lower rate of sexual satisfaction among Chinese people to rapid economic growth, which inevitably increases work and social pressure.Health problems associated with a modern lifestyle, such as diabetes and hypertension, are also to blame, he said.Jiang said his department of andrology used to receive about 10 patients a day 10 years ago. Now the figure has risen to more than 250.Rising awareness of sex and a more open attitude toward the once-taboo topic among the public also contributed to higher sexual expectations, he said.The survey also revealed that about 30 percent of respondents in the 35-55 age group had sex less than once a week."That rate is quite low, compared with the global average of 103 times a year, or 1.98 times a week," said Yang Xiong, who heads the social survey center at the Shanghai Academy of Social Sciences.Only 16.9 percent of respondents said that they had sex more than 10 times a month. Most respondents had sex three to nine times every month.About 8 percent of respondents said that they basically had no sex at all or it was too infrequent to be classified.The survey seemed to find that the more you made, the less you had. Those who earned at least 9,000 yuan (,400) a month had less sex than those who earned less, according to the survey.Among those making more than 9,000 yuan per month, over 70 percent said they had sex less than twice a month, compared with 16.5 percent for those with a monthly salary of less than 6,000 yuan.The survey also found that when people run into problems with their sex lives, 83 percent turn to the Internet, rather than professionals, for help. Less than 6 percent said they would see doctors to solve sex-related problems.Nearly 70 percent of those polled said they suffered from sexual health problems, such as erectile dysfunction (ED)."Many patients, especially men, are reluctant to see a doctor, which they think harms their manhood," Jiang said.According to a study conducted by the Chinese Society of Andrology, at least 40 percent of men aged 40 and above suffered from erectile dysfunction, roughly the global average.But Yang, from the Shanghai academy, noted that surveys conducted online tend to produce far different results than those conducted face-to-face.He expressed reservations about the survey's accuracy and said the public should only use the results for reference.

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, July 17 (Xinhua) -- Iraqi Prime Minister Nouri al-Maliki arrived in Beijing Sunday night for his first official visit to China as a guest of his Chinese counterpart Wen Jiabao.During al-Maliki's stay in China from Sunday to Thursday, President Hu Jintao will meet with him, and Premier Wen will hold talks with the Iraqi prime minister, Chinese Foreign Ministry spokesman Hong Lei said earlier.China and Iraq share a traditional friendship, Hong said, adding that the two countries have witnessed smooth development of bilateral relations, steadily growing economic cooperation and increasing cultural exchanges."China is ready to work with the international community and to continue to provide assistance for the Iraqi people to improve their livelihoods," said the spokesman.

  

VIENNA, Aug. 11 (Xinhua) -- Austrian researchers have developed a method of using fungi and produced enzymes to split Polyethylene Terephthalate (PET) material into their initial state, enabling the recovery of all individual components, said the Austrian Center of Industrial Biotechnology (ACIB) Thursday in a press release.Enzyme is a special protein that acts as biological catalyst, for example, bacteria and fungi in the nature can break down long chain molecules.Researchers from the Technical University of Graz, the Technical University of Vienna and the Agricultural University of Vienna jointly found that efficient enzymes are capable to break and split PET into small fragments.With different methods, the researchers forced the fungi to overproduce their precious "split-tools" after they are modified and improved by genetic engineering.Through the new method developed by the ACIB, it is now possible to decompose the PET polymer to its initial monomers with high product quality and from this to produce new high-quality materials again.This circuit avoids waste and thus saves resources and is friendly to the environment, said Geog Guebitz, head of the Research Department on Enzymes and Polymers in the ACIB.He further explained that the ACIB has established a partnership with some industrial enterprises to carry out application experiments. From the current splitting time of 24 hours, the researchers expect to shorten the whole process to "a few hours," he added.PET is a common plastic material in the polyester family, widely used in the textile industry. PET film is mainly used in electrical insulation materials, which can be also used for production of film, X-ray films and computer taps, even to produce plastic bottle and other blow molding products.
