WASHINGTON, April 13 (Xinhua) -- The U.S. Food and Drug Administration (FDA) announced on Wednesday that it has approved the cPAX Aneurysm Treatment System for surgery on brain aneurysms that are difficult to manage because of their size and shape.An aneurysm is a bulge in the wall of a blood vessel, which can rupture as it increases in size, causing hemorrhage or death. Brain aneurysms often produce no symptoms until they grow and press on nerves in the brain, or until they begin to leak blood or rupture.Aneurysms can be repaired in two ways: surgeons can close the base of the aneurysm with a surgical clip, or use a technique commonly known as coiling, in which surgeons use a catheter to thread metallic coils through a blood vessel in the groin and into the blood vessel in the brain that contains the aneurysm. Surgeons then fill the aneurysm with the detachable coils, which block it from circulation and cause blood to clot, effectively destroying the aneurysm.Aneurysms larger than 10 millimeters are difficult to treat with clipping or coiling. The cPAX device system is indicated for use in those brain aneurysms."Like coiling, the cPAX Aneurysm Treatment System is a form of endovascular repair," said Christy Foreman, director of the Office of Device Evaluation in the FDA's Center for Devices and Radiological Health. "But instead of tiny metallic coils, it uses a special polymer material to fill the space within the aneurysm."According to the FDA, the cPAX device system is indicated for use in adults aged 22 and older and should not be used in patients with an active infection or in those in whom anticoagulation and antiplatelet therapy is contraindicated.

STOCKHOLM, Jan. 26 (Xinhua) -- China's railway network, already the world's longest, is developing at record high speed and is to be doubled soon, Swedish daily Svenska Dagbladet reported on Wednesday."China's goal is to connect all important cities with railway lines," the report said.Collaborating with German Siemens, Japanese Kawasaki and Bombardier both in Canada and Sweden, China has built its own high-speed train CRH380A that can reach 486 kilometers per hour, cutting the journey between Beijing and Shanghai in half to about 4 hours.Construction of the high-speed railway network will also cover inland China, the report said. It aims to encourage more investment to move from coastal areas to inland China and ultimately raise the living standards in those regions.Within the next five years, a total of 3.5 trillion yuan (over 500 billion U.S. dollars) will be invested in high-speed track construction and train manufacturing, averaging at about 700 billion yuan (over 100 billion dollars) each year.Swedish companies such as Atlas Copco, SKF and Trelleborg have participated in China's railway and high-speed train development, according to the report.Hans Rosling, a development expert and also professor at Karolinska Institutet in Sweden, was quoted as saying that the construction of the high-speed railway network will bring about "good economy, good education, good medical care, better and longer life, all good things."

MOSCOW, Jan. 24 (Xinhua) -- Russian President Dmitry Medvedev and visiting Chinese State Councilor Dai Bingguo held talks here on Monday, discussing prospects for the development of cooperation between the two countries.Medvedev and Dai Bingguo discussed the development of Russian- Chinese bilateral cooperation and interaction on the international arena.The Russian president said the Sino-Russian strategic partnership of coordination is developing further in all aspects, as the leaders of the two nations kept close contact during last year and cooperation in the economic and trade sphere has been deepened.Russia sees China as its closest partner, a position that will never be changed, Medvedev stressed.Russia is willing to work together with China to promote all- around cooperation and coordination on international and regional issues, Medvedev said.He said the strategic security talks between Russia and China, a major goal of Dai's current visit, have served as an important channel for bilateral coordination and exchanges, and played a pivotal role in enhancing bilateral strategic mutual trust.Dai Bingguo, who arrived in Moscow Sunday for a three-day visit, said that the first ten years of the 21st century had been important for Sino-Russian relations.China attaches great importance to the strategic coordination with Russia and is willing to work with Russia to develop their strategic partnership of coordination at a higher stage, the Chinese state councilor said.

LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.
