BEIJING, Sept. 14 (Xinhuanet) -- The U.S. Food and Drug Administration (FDA) on Monday announced a recall on a drug infusion pump of Medtronic, the Associated Press reported.The recalled drug pump was called "SynchroMed II", including models of 8637-20 and 8637-40, distributed between 2004 and July 2011.Drug infusion pump was used to deliver the drugs for patients to treat chronic pain, spasms as well as other conditions.The pumps' malfunction could put patients in the risk of either recurrent or withdrawal symptoms, which could be life-threatening, FDA warned.There were 55 reported cases and one death related to the drug withdrawal, among a total 139,653 SynchroMed II pump implants worldwide, FDA notified.The problem was due to a film within the pump's battery that could stop the therapy, FDA said.Medtronic, the U.S. medical technology company based in Minneapolis, is not recommending patients to remove the pumps, but instead, encourage patients to contact their doctor if they hear the device alarm.

BEIJING, June 21 (Xinhua) -- China will launch a new icebreaker for use during an upcoming 2013 polar expedition, a senior oceanic official said on Tuesday.Both the new icebreaker and Xuelong ("Snow Dragon"), an icebreaker that operated in Antarctica, will form an Arctic-Antarctic maritime research team."China will have at least two icebreakers concurrently operating at both the north and south poles," Chen Lianzeng, deputy director of the State Oceanic Administration, told a national conference on polar research, which has been the first since 1984 when the country started expeditions in polar regions.The new icebreaker will boast facilities that will allow it to research the oceanic environment, integrate data for real-time oceanic monitoring, deploy and retrieve detectors and conduct aerial studies using helicopters, Chen said.The two icebreakers will conduct expeditions in polar regions for more than 200 days annually, he said.Fixed-wing aircraft will also be added to the expedition team before 2015, allowing researchers to be transported between China's Zhongshan and Kunlun research stations and Antarctica's Grove Mountains.The Kunlun station went into operation in early 2009 as the first Chinese research station on Antarctica's inland. The Zhongshan station, established in 1989, now serves as a supply base for the Kunlun station.A written comment by Vice Premier Li Keqiang sent to the conference said the polar research, a magnificent feat of the mankind, has great significance for China's oceanic work and sustainable development."Over the past two decades, China's polar research made great achievements and became influential globally," Li said.Li encouraged Chinese scientists to actively participate in international exchanges and cooperation, safeguard national interests and contribute to the peaceful use of polar regions.Since the early 1980s, China has sent 27 Antarctic expedition teams and completed four research missions to the Arctic Ocean.Besides the Xuelong icebreaker, China has built three Antarctic stations -- Changcheng (Great Wall), Zhongshan and Kunlun -- and one Arctic station -- Huanghe (Yellow River) Station.

WASHINGTON, June 21 (Xinhua) -- Brain cancer patients who are able to exercise live significantly longer than sedentary patients, U.S. scientists at the Duke Cancer Institute have reported.The finding, published online this week in the Journal of Clinical Oncology, adds to recent research that exercise improves how cancer patients feel during and after treatments, and may also extend their lives.The study enrolled 243 patients with advanced recurrent gliomas, lethal brain malignancies that typically result in a median life expectancy of less than six months. The patients who reported participating in regular, brisk exercise -- the equivalent of an energetic walk five days a week for 30 minutes -- had significantly prolonged survival, living a median 21.84 months versus 13.03 months for the most sedentary patients."This provides some initial evidence that we need to look at the effects of exercise interventions, not only to ease symptoms but also to impact progression and survival," said Lee Jones, associate professor in the Duke Cancer Institute and senior author of the study.

BEIJING, Sep. 13 (Xinhuanet) --Experts have called for a national drug-control system after a nationwide deficit of a life-saving drug, which has lasted at least three months.Doctors at a Beijing hospital said some specialized hospitals, which perform hundreds of cardiac operations every month, have been paralyzed by their lack of protamine sulfate, which is commonly administered after heart surgery to reverse the anticoagulant effects of heparin.The earliest report of a shortage was in Hubei province on July 21. This was followed by reports of shortages in Guangdong, Shandong and Liaoning provinces.The Shandong newspaper, Qilu Evening News, quoted a regional sales manager, surnamed Zhuang, as saying the province had been allocated 150 doses of protamine sulfate after Shanghai No 1 Biochemical and Pharmaceutical Co Ltd recently resumed production of the drug."But its monthly use here is usually 10,000 doses," he said.The Ministry of Health has denied it is responsible for supplies of the drug and passed the buck to the State Food and Drug Administration, claiming the latter is responsible for the supervision of medicines.Shen Chen, head of the publicity office of the State Food and Drug Administration, said he was unaware of the shortage, but said the administration is responsible for the quality of medicines, not the supply."Development and reform authorities oversee the medicines' prices, while the industrial and commercial authorities oversee the storage. The food and drug departments only cover the approval and quality of medicines."Industry insiders said one of the reasons for the shortage was the low profit margin, which discourages companies from mass producing the drug."Some companies can't earn enough to recover their costs, therefore it is almost impossible to maintain their enthusiasm for continuing production," said Lu Guoping, secretary-general of the Shanghai Pharmaceutical Trade Association.Lu said the government should issue policies to prevent future shortages of such medicines to avoid possible nationwide public health incidents.Yi Shenghua, a lawyer at Beijing Yingke Law Firm, said the country should have a unified system to guarantee the normal supply of medicines that are widely used and drug manufacturers should fulfill their responsibilities to society, even though there is no law stipulating they should produce specific medicines.He came up with two ways to deal with the problem of companies only producing profitable drugs."The government can order businesses to manufacture a certain amount of cheap medicines. Or it can offer financial assistance to subsidize cheap, but life-saving medicines."
