WASHINGTON, Nov. 18 (Xinhua) -- The U.S. Food and Drug Administration (FDA) on Friday approved Erwinaze to treat patients with acute lymphoblastic leukemia (ALL), who have developed an allergy to E. coli derived asparaginase and pegapargase chemotherapy drugs used to treat ALL.Acute lymphoblastic leukemia is a type of cancer in which the bone marrow makes too many lymphocytes, a type of white blood cell. White blood cells help the body fight infection and are formed in the bone marrow.Erwinaze is injected directly into the muscle three times a week and works by breaking down one of the body's protein building blocks (the amino acid, asparagine) that is present in the blood, and is necessary for the growth of all cells. Leukemia cells cannot produce this protein building block. When a patient is treated with Erwinaze the leukemia cells die. Normal human cells are able to make enough asparagine for their own needs through biosynthesis and will not be affected by treatment with Erwinaze."The approval of Erwinaze underscores the FDA's commitment to the approval of drugs for conditions with limited patient populations with unmet medical needs using novel trial endpoints," said Richard Pazdur, director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research.Side effects associated with Erwinaze treatment include serious allergic reactions, inflammation of the pancreas, high blood levels of liver enzymes, blood clotting, bleeding, nausea, vomiting and high blood sugar.

BEIJING, Jan. 20 (Xinhua) -- China will regulate the production and sale of cosmetic colored contact lenses by including them in its list of items classified as "medical apparatus."Some people wear such non-corrective colored contacts to change or enhance eye color for cosmetic and fashion purposes.As these contacts are not for vision correction and medication purposes, they are currently off limits to the country's medical administration and regulators, said a statement published on the website of the State Food and Drug Administration on Thursday.However, with the increasingly popular use of cosmetic contacts, safety and quality problems due to the regulation loophole are likely to harm consumers' health, and the administration has decided to expand the current medical regulation on contact lenses to cover cosmetic ones, the statement said.It explained that the administration will soon issue a notice to ban the manufacture and sale of these contacts without proper registration and licenses.The statement also warned consumers of the risks of these contacts and suggested they carefully choose and use such products.

SAN FRANCISCO, Nov. 22 (Xinhua) -- Microsoft announced on Tuesday that it has acquired video search engine VideoSurf.In a press release, Microsoft said it will integrate VideoSurf' s technology across its entertainment platform to augment the Xbox 360 ecosystem and evolve search and discovery of entertainment content on Xbox LIVE.Details of the deal were not disclosed. Technology news site TechCrunch cited Israeli business newspaper Calcalist as saying that the company was bought for about 70 million U.S. dollars.The San Mateo, California-based company, founded by four Israelis in 2006, offers a technology that "sees" frames inside videos to make discovering content fast, easy and accurate.Since its founding, VideoSurf has raised 28 million dollars from several sources, including Facebook chief operating officer Sheryl Sandberg and her husband, as well as former U.S. vice president Al Gore.Last month, Microsoft announced that it will bring cable television content to its Xbox video game console over the holiday season, expanding the console into an entertainment hub.The software giant said Tuesday that the latest acquisition will make it easier for world-class video partners to take full advantage of advanced search features.

BEIJING, Oct. 21 (Xinhua) -- China on Friday urged the European Union (EU) to recognize its full-market economy status at an early date and properly settle trade disputes amid the tumbling world economy."China hopes Belgium will exert its influence to push for an early recognizing of China's full-market economy status and remind the EU to be cautious on and restrain from using trade remedy measures," Vice Premier Wang Qishan told visiting Crown Prince Philippe of Belgium.Wang urged the 27-member bloc, also China's largest trade partner, to properly settle trade disputes with China during the talks at Diaoyutai State Guesthouse in downtown Beijing.Chinese Vice Premier Wang Qishan (R) shakes hands with Belgian Crown Prince Philippe in Beijing, capital of China, Oct. 21, 2011."China has contributed a lot to the world economy by recording a 9.4 percent growth in the first three quarters of this year while adjusting its economic structure and managing inflation expectations," Wang said.Prince Philippe, accompanied by a 450-member business delegation, is here to tap the Chinese market and seek investments from China, the world's top holder of foreign exchange reserves.During the 10-day trip, the delegation will visit the Chinese cities of Tianjin, Guangzhou, Shenzhen, Shanghai and Chongqing and is expected to sign about 40 contracts.Wang said China will expand two-way investment with Belgium, and enhance support to the two states' small and medium-sized enterprises via the China-Belgium direct equity investment fund.China-Belgium trade has continued to surge since the two states forged diplomatic ties in 1971, when the bilateral trade volume was only 20 million U.S. dollars, much less than the 22.1 billion U.S. dollar record in 2010."We could expand cooperation in two-way investment, trade, finance, chemical industry, environmental protection, logistics, and green economy," Wang said.

UNITED NATIONS, Nov. 21 (Xinhua) -- Dramatic progress in science, political leadership, and results indicate that 2011 was a "game changing" year for the international AIDS response, and much progress has been made in 2011 to check AIDS-related deaths since 1997, the peak of the epidemic, a new report released by the Joint United Nations Program on HIV/AIDS (UNAIDS) said on Monday."The Report on the Global AIDS Epidemic 2011" found that new infections were reduced by 21 percent since 1997, and deaths from AIDS-related illnesses decreased by 21 percent since 2005, according to the report.Furthermore, 47 percent (6.6 million) of the estimated 14.2 million people eligible for antiretroviral therapy treatment in low- and middle-income countries were accessing treatment, in increase of 1.35 million people since 2009.The report also found early signs that HIV treatment is having an impact on reducing the number of new HIV infections. As treatment reduces the viral load of a person living HIV to almost undetectable levels, it also reduces the risk of transmitting the virus to an uninfected partner, according to the report. Studies also show that treatment can be up to 96 percent effective in preventing HIV transmission among couples.Eleven countries, including many Sub-Saharan African countries, reached "close to universal access" for AIDS treatment, which is determined to be 80 percent access, in 2011.Botswana made the most dramatic progress in scaling up access to treatment, the report said. While sexual patterns remained relatively stable in the country since 2000, access to treatment increased from less than 5 percent in 2000 to more than 80 percent in 2011.Despite progress, however, the report does note that 2011 marks an unprecedented high the number of people infected with HIV worldwide.Globally, an estimated 34 million people are currently living with the infection. Approximately 2.7 million got infected with the virus in 2010, and as many as 1.8 million people died of AIDS- related illnesses in 2010.Yet the report also notes estimates that as many as 2.5 million deaths are estimated to have been averted in low- and middle- income countries due to increased access to HIV treatment since 1995."Now is not the time to reduce our efforts despite some good news on reducing new infections. Infections are decreasing, but not rapidly enough," said Kim Nichols, executive director of African Services Committee, on Monday at a press conference."There are fewer AIDS deaths, but with the number of infections increasing, prevention has to be the mainstay of our response," Nichols said.Indeed, the UNAIDS report calls for a new framework for investments which are focused on "high-impact, evidence-based, high-value strategies," according to a press release from the UNAIDS website.The framework, which aims to achieve universal access to treatment and prevention centers by 2015, requires a 22-24 billion US dollar funding increase by 2015.Given the withering state of the global economy -- donor funding for the AIDS response has dropped from 7.6 billion in 2009 to 6.9 billion in 2010 -- raising that kind of money may be a long shot. Regardless, UNAIDS'new investment plan calls for smarter uses of less money.According to the report, the framework will focus on high-risk populations like sex workers, men who have sex with men, and people who inject drugs and prevent infections among children, as well as invest in behavior change programs, condom promotion, and treatment, care and support for people living with HIV."The world faces a clear choice: maintain current efforts and make incremental progress, or invest smartly and achieve rapid success in the AIDS response," says the UNAIDS report.
