BEIJING, Dec. 26 (Xinhua) -- China has launched a one-year inter-agency national campaign aiming to return most street children home, the Ministry of Civil Affairs (MCA) said Monday.The MCA will lead the campaign, which is joined by the ministries of education, public security, financial, health, human resources and social security, and housing and urban-rural development, an MCA statement said."We will try our best to identify most street children in cities and send them home by the end of 2012," the statement said.Minister Li Liguo of Civil Affairs said, ministries concerned should strengthen communication and coordination, and speed up the revision of regulations on the relief of city beggars and vagrants.The MCA also urged provincial governments to set up special offices coordinating the campaign. Several provinces, such as Hebei and Yunnan, have been working on this, the statement said.Police will step up their efforts to identify and rescue street children who wander near railway stations, major tourist sites, business areas and subway stops, while civil affairs departments will assist investigation and provide shelter for homeless children, the statement said.Urban communities and neighborhoods are asked by the ministry to report homeless children to local police. Police and civil affairs departments will cooperate to ascertain the whereabouts of their parents or guardians.In home places of street children, education departments are urged to send them to schools or vocational schools, and those from needy families will have their tuition reduced or waived.Health departments are required to offer street children easy access to medical facilities in emergency cases. Hospitals listed in the campaign will treat sick street children free of charge.

BEIJING, Oct. 18 (Xinhuanet) -- Autism can likely develop when low birth weight babies are combined with other factors such as environment and genetic predisposition, new research suggests.Researchers from the University of Pennsylvania School of Nursing and School of Medicine identified 1,105 children who weighed less than 2,000 grams at birth between Oct. 1, 1984, and July 3, 1989.Sixteen years later, researchers were able to reach 623 of those children, and used a questionnaire to screen them for autism spectrum disorders.When 189 of the children turned 21 years old, 60 percent of those who screened positive for an autism spectrum disorder, and 24 percent of those who screened negative with the condition. All in all, the rate of autism spectrum disorders among the study participants with low birth weights was five times higher than the general.Autism spectrum disorder makes people have difficulty communicating, difficulty interacting in social situations, and restrictive or repetitive interests, said study co-author Jennifer Pinto-Martin, a researcher in the University.Those with mild autism spectrum disorders, "may only want to talk about one subject," Pinto-Martin said. "They're perfectly functional. They can go to college. They can hold a job." Premature babies are often born with low birth weights, though full-term babies can also have the condition. The research suggests a need not only for better prenatal care to reduce the number of premature babies, but also a need for early diagnosis and intervention for people with autism.

WASHINGTON, Nov. 14 (Xinhua) -- A novel study in twins found that exposure to trichloroethylene (TCE) -- a hazardous organic contaminant found in soil, groundwater, and air -- is significantly associated with increased risk of Parkinson's disease (PD). Possibility of developing this neurodegenerative disease is also linked to perchloroethylene (PERC) and carbon tetrachloride (CCI4) exposure, according to the study appearing in Annals of Neurology on Monday.The National Institute of Neurological Disorders and Stroke estimates that as many as 500,000 Americans have PD and more than 50,000 new cases are diagnosed annually. While there is much debate regarding cause of PD, studies suggest that genetic and environmental factors likely trigger the disease. Several studies have reported that exposure to solvents may increase risk of PD, but research assessing specific agents is limited.The current epidemiological study, led by Samuel Goldman and Caroline Tanner with The Parkinson's Institute in Sunnyvale, California, investigated exposure to TCE, PERC and CCI4 and risk of developing PD. The team interviewed 99 twin pairs in which one twin had PD and one didn't, inquiring about lifetime occupations and hobbies. Lifetime exposures to six specific solvents previously linked to PD in medical literature -- n-hexane, xylene, toluene, CCI4, TCE and PERC -- were inferred for each job or hobby.The findings are the first to report a significant association between TCE exposure and PD -- a more than six-fold increased risk. Researchers also found that exposure to PERC and CCI4 tended toward significant risk of developing the disease. "Our study confirms that common environmental contaminants may increase the risk of developing PD, which has considerable public health implications," commented Goldman in a statement.TCE, PERC and CCI4 have been used extensively worldwide, with TCE noted as a common agent in dry-cleaning solutions, adhesives, paints, and carpet cleaners. Despite the U.S. Food and Drug Administration (FDA) banning the use of TCE as a general anesthetic, skin disinfectant, and coffee decaffeinating agent in 1977, it is still widely used today as a degreasing agent. In the U.S., millions of pounds of TCE are still released into the environment each year and it is the most common organic contaminant found in ground water, detected in up to 30 percent of drinking water supplies in the country.In a release issued on Sept. 28, 2011, the Environmental Protection Agency announced that TCE is carcinogenic to humans.
