BEIJING, July 22 (Xinhuanet) -- Regulation is needed to govern rapidly expanding research in animals containing human tissue or genes, according to the Britain's Academy of Medical Sciences.Using animals with limited humanized traits is not new. Genetically engineered mice containing human DNA are already a mainstay of research into new drugs for diseases like cancer.For instance, Chinese scientists have already introduced human stem cells into goat fetuses and U.S. researchers have studied the idea of creating a mouse with human brain cells.But Martin Bobrow, a professor of medical genetics at the University of Cambridge, who led the Academy's working group, said there were three areas of particular concern."Where people begin to worry is when you get to the brain, to the germ cells, and to the sort of central features that help us recognize what is a person, like skin texture, facial shape and speech," he said.His report recommends that government should put in place a national expert body, working within the existing system for regulating animal research, to oversee such sensitive areas.British ministers said they welcomed the report and would consider its recommendations carefully.

WASHINGTON, Aug. 2 (Xinhua) -- A new study has identified the recent emergence of a multidrug-resistant strain of Salmonella that has a high level resistance to ciprofloxacin, a common treatment for severe Salmonella infections. The study was published on-line Tuesday in The Journal of Infectious Diseases.Francois-Xavier Weill at the Pasteur Institute in France and colleagues studied information from national surveillance systems in France, England and Wales, Denmark, and the United States. The data showed that a multidrug-resistant strain of Salmonella, known as S. Kentucky, infected 489 patients in France, England and Wales, and Denmark between 2000 and 2008. In addition, researchers reported that the first infections were acquired mainly in Egypt between 2002 and 2005, while since 2006 the infections have also been acquired in various parts of Africa and the Middle East. The absence of reported international travel in approximately 10 percent of the patients suggests that infections may have also occurred in Europe through consumption of contaminated imported foods or through secondary contaminations.In this study, multidrug-resistant S. Kentucky was isolated from chickens and turkeys from Ethiopia, Morocco, and Nigeria, suggesting that poultry is an important agent for infection. The common use of fluoroquinolones in chicken and turkey production in Nigeria and Morocco may have contributed to this rapid spread, according to the researchers.This study highlights the importance of public health surveillance in a global food system. The investigators reported that they will continue to monitor this multidrug-resistant strain as well as help strengthen the capacities of national and regional laboratories in the surveillance of Salmonella and other major foodborne pathogens through the World Health Organization Global Foodborne Infections Network.Salmonella infection represents a major public health problem worldwide. An estimated 1.7 million such infections occur in North America each year. More than 1.6 million cases were reported between 1999 and 2008 in 27 European countries. Although most Salmonella infections produce only mild gastroenteritis, elderly and immunocompromised patients are especially at risk for life- threatening infections. These cases are typically treated with antimicrobials called fluoroquinolones, such as ciprofloxacin.

BEIJING, July 13 (Xinhuanet) -- Gasoline powers vehicles all around the world, but a sick Chinese man has been drinking the sticky liquid for 42 years under the illusion that it can relieve his physical pain.Chen Dejun, 71, lives by himself in shabby thatched cottage on a hill in Shuijiang township, Nanchuan district of southwest China's Chongqing municipality. The short and bony man said he drinks 3 to 3.5 kilograms of gasoline every month, which he buys from a station at the foot of the hill.Chen is known locally as a stonecutter and master of weaving bamboo with a good business sense. But he’s also known for his undying love of drinking gasoline.He developed the habit back in 1969 when he suddenly began coughing and felt pain in his chest. Seeing no progress after trying some medicine, he took up the folk remedy of drinking kerosene, Chongqing Evening News reported.It turned out to be helpful for him after the first sip, and he since became addicted to kerosene. Then he moved on to gasoline.Chen said it is hard to calculate exactly how much gasoline he has swallowed throughout his life, but the newspaper reported Chen has consumed an estimated 1.5 tons over the past 42 years.Chen's wife Yuan Huibi and their three sons tried many times to stop Chen's addiction to gasoline, but those efforts only made the family relations tense. Eight years ago Chen moved to the cottage to live alone.Sources from Honglou Hospital in Chongqing said Chen‘s health is fine despite having symptoms of emphysema. Chen refused to receive free check ups from the hospital.Feng Fu, an associate professor with the Second Hospital Affiliated to Chongqing Medical University, said Chen may have developed some resistance to gasoline. Otherwise, Feng said, it would be impossible for Chen to live. Feng also said gasoline may only work as anaesthetic for Chen but can’t cure his pain.
