SYDNEY, July 15 (Xinhua) -- The world's first drug to increase life expectancy of people with advanced melanoma has been approved for use in Australia, local media reported on Friday.The breakthrough drug Yervoy got approval from the Therapeutics Good Association (TGA) on Friday amid hopes it could add two years to the life of people with the most lethal form of skin cancer but for whom other treatments have failed, the Australian Associated Press (AAP) said.Clearance for the drug's use in Australia follows similar approvals by the U.S. health regulator in March.Yervoy works by attacking and destroying cancer cells.Patients are hooked up to an intravenous drip once every three weeks for a total of four doses.Professor Peter Hersey, consultant immunologist to the Melanoma Institute Australia, said no other drug had improved survival rates like Yervoy."Not all patients respond to it but those who do have a good chance of living longer than they would have otherwise," Hersey told AAP.While it may improve survival rates, Yervoy can produce side effects from diarrhea and vomiting to serious blood infections and kidney failure.The average survival time for people with advanced melanoma is just six months.A global study of 676 people with melanoma found that 45 percent of patients given Yervoy were still alive after one year, according to AAP.More than 20 percent lived at least two years, with a small number managing to survive for six years.A separate study, published in June, which showed similarly improved survival rates for patients with newly diagnosed advanced melanoma, has raised hopes that Yervoy could be made more widely available.Melanoma is the fourth most common cancer in Australia, with 10, 300 people diagnosed each year.

SAN FRANCISCO, Sept. 12 (Xinhua) -- Amazon.com Inc. is talking with book publishers to launch a rental subscription service for digital books, U.S. media reported on Monday.Several publishing executives said they aren't enthusiastic about the idea because it could lower the value of books and it could also strain their relationships with other retailers that sell their books, The Wall Street Journal quotes people familiar with the matter in a report.The Seattle-based company is considering a digital book library featuring old titles, which would be available to Amazon Prime subscribers, who currently pay 79 U.S. dollars a year for access to digital library of movies and TV shows and unlimited two-day shipping, said the report.Amazon would offer book publishers a substantial fee and could limit the amount of books that Amazon Prime customers could read for free every month, the report cited some sources as saying.The online retailing giant makes the popular electronic reader Kindle and is also reported to launch a color touchscreen tablet before October to compete with Apple's iPad and other devices in the increasingly crowded tablet computer market.The proposal is another sign that retailers are looking for more ways to deliver content digitally as customers increasingly read book and watch TV on personal computers, tablets and other electronic devices, said The Wall Street Journal report.

BEIJING, Sep. 16 (Xinhuanet) -- Government incentives are important to pave a low-carbon road to economic growth, but companies that improve their industry models and technologies are the main players and also benefit receivers, noted officials and industry insiders at the Summer Davos forum held in Dalian on Sep 14."The most important thing is to have the right direction," said Gao Jifan, chairman and CEO of Trina Solar, a national leading solar panel manufacturer in China.According to Gao, new energy solutions such as solar power, is the "right direction" of future growth, although many deficiencies still exist today. "As long as we have the direction correct, we can succeed as last. But this also requires policies, technologies and investment," he said.Malini Mehra, founder and CEO of the Centre for Social Markets, a non-profit organization that promotes sustainability, said there are two ways in which the governments can support low-carbon businesses to continue along a "green" path."The first is to provide some means of recognizing their good work," she said. And the second is building a measuring system to "verify which company is actually doing well, not just talking about doing well".Preferential policies are only the foundation, said Gao. "We must have a good overall plan along with advanced technologies to bring value back to the investors."Gao envisions that most of the world’s families will have "zero-consumption" houses with energy supply and storage systems relying purely on solar power by 2020.Without grid limitations, the technology can be used everywhere in the world, especially in the less developed areas."The cost of solar technologies has been on the decline over the past few years because of policy incentives and innovations of companies around the world," said Gao.A solar panel producing one watt’s electricity cost in 2005, but now it is reduced to only .2 to .3, he explained."This is the result of technological innovations and large-scale manufacturing. And it makes us more confident to see the solar energy to become a major part of the energy system in the future."Being low-carbon also helps a company attract clients because it is the current fashion and customers are more likely to choose low-carbon products, noted Klaus Kleifeld, CEO of the US aluminum products maker Alcoa Inc."The generation that we recruit today has a very different social consciousness and standards," he said. "They want to see and only want to work for companies that are sustainable."

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.
