BEIJING, Oct. 11 (Xinhuanet) -- An experimental drug that can remove amyloid plaques from the brains of Alzheimer's patients is being developed by Swiss Roche Holding AG in a small early-stage study, according to a report published in the Archives of Neurology on Monday.Researchers suspect the build-up of such plaques may be a cause of the memory robbing disease, although that theory has yet to be definitively proved. Gantenerumab, a biotech drug designed to bind to amyloid plaques in the brain and remove them, is being targeted at the early stages of Alzheimer's with the hope it can slow progression of the disease while patients are still able to function.The Phase I study of 16 Alzheimer's patients tested gantenerumab at two doses against a placebo over six months of treatment.The Roche drug led to a dose-dependent reduction of brain amyloid, while amyloid load increased in patients receiving a placebo, the report said.The next step will be to investigate whether removal of brain amyloid translates into clinical benefit for patients at doses of the experimental drug that are well tolerated and safe, the report said.Much larger trials and further study will be needed to fully understand how gantenerumab works and whether it can stave off Alzheimer's, said the report.Roche is approaching the disease far earlier because amyloid accumulates for 15 years before dementi.

BEIJING, Jan. 6 (Xinhua) -- China will bring its nurse population to 2.86 million by 2015, meaning there will be 2.07 nurses for every 1,000 people, according to a blueprint on nursing issued Friday by the Ministry of Health (MOH).By the end of 2010, China has registered 2.05 million nurses and there were 1.52 nurses for every 1, 000 Chinese.Even by 2015, the ratio of registered nurses for 1,000 people in China is five times fewer than countries in the European Union and the United States by current standards.By 2015, the ratio of licensed doctors to nurses will climb from 1:1 to 1:1.2, according to the blueprint.China also plans to provide more training for head nurses in large hospitals and make nursing services accessible to households and communities, according to the blueprint.The five-year nursing development plan said the government will further standardize its nurse management system and deepen health care reform in public hospitals over the next few years.The total number of registered nurses reached 2.05 million in 2010, marking a 52 percent jump from 2005, according to the blueprint.

HONG KONG, Oct. 13 (Xinhua) -- Computer and electronic device maker Lenovo, listed in both Hong Kong and New York, has replaced Dell to become the world's second largest personal computer company, Lenovo said Thursday.Lenovo made the remarks in a statement, citing figures released by International Data Corporation (IDC), a global provider of business intelligence for the consumer technology market.Following five quarters as the fastest-growing PC maker among the world's top vendors, the preliminary IDC data reported that Lenovo has achieved record market share of around 13.7 percent and record quarterly shipment volume of some 12.6 million units.Lenovo CEO Yang Yuanqing said his company had surpassed two competitors to capture the No. 2 spot in worldwide PCs in just two quarters and it was the highest rank that Lenovo has achieved in worldwide PC sales.Given current competitive environment, the new achievement positioned Lenovo as a strong challenger to ultimately become the global market leader, Yang said in the statement."We are growing in the enterprise and the consumer space. And our customers know we are fully committed to the PC market for the long term," he said.At the same time, the Chinese multinational would continue investing in innovative products that would help drive the convergence of technologies and services across all four screens -- smart phones, tablets, PCs and smart TV, Yang said."We must deliver a great user experience across all platforms to achieve our goal and become the leading personal technology company in the world."Lenovo is a personal technology company and a global Fortune 500 company with annual sales worth 21 billion U.S. dollars. It serves customers in more than 160 countries and regions.
