BEIJING, Dec. 28 (Xinhuanet) -- A vagrant boy sat all huddled up in a corner of Beijing Railway Station, trying to keep himself warm in the chilly wind on Tuesday afternoon.He could only remember that he was 16 and that his home was far away from Beijing but failed to provide other vital information such as his name or home address.Two officials from the social assistance center for the homeless in Beijing's Dongcheng district came to his assistance within half an hour of receiving a passer-by's call. The boy was taken to the center's office for some paper work and then sent to a shelter for the homeless in Fengtai district.A teenager, unsure of his identity and living on a street corner near Beijing Railway Station, is helped by China Daily photographer Wang Jing on Tuesday before being taken to a care center."Our center handles about three or four similar cases every month. Those whose family cannot be contacted immediately are sent to the shelter," said Cao Hui, an official who came to the railway station to pick up the boy.The method of collecting vagrants and sending them to shelters would include an extra step by 2013, according to a notice jointly issued by eight government departments, including the Ministry of Civil Affairs (MCA), on Monday.The circular required the public security, urban management authorities and rescue centers nationwide to collect blood samples from vagrant children. Their DNA information will be recorded and checked against the national DNA database to see if these could be matched with that of missing children's parents', in case they were kidnapped or stolen by criminals.The eight government departments will start a year-long national campaign in 2012, aiming to return street children to their homes, which will be led by the MCA.The MCA urged provincial governments to set up special offices to coordinate the campaign.Civil Affairs minister Li Liguo said on Monday that the ministry will speed up revising the management regulations related to the homeless and beggars in cities, introduced in 2003. Detailed rules about how different government departments should cooperate with each other to help vagrant children would be formulated in the revised regulation.The notice also urged the civil affairs authorities to organize social workers to provide one-on-one psychological counseling and aid services to street children.Educational authorities in locations where the vagrant children are originally from are required to facilitate their returning to schools or vocational institutions. Those from poor families can have their school fees reduced or waived.Yu Jianrong, a professor with the Chinese Academy of Social Sciences and an initiator of a grassroots campaign to help child beggars, begun in January, applauded the government's consistent efforts to help street children to resume a normal life."The notice definitely shows the government's determination to keep children away from begging or performing on the street.""However, seeing no vagrant children on the street doesn't mean all problems have been solved. The government should make more efforts to improve the social security network for children," he added.Ablikim has been working with a non-governmental organization in Urumqi of Northwest China's Xinjiang Uygur autonomous region that has helped about 300 children - originally from Xinjiang who turned up on the streets of more prosperous cities, begging and picking pockets - to reunite with their families or put them in child rescue centers.The 27-year-old Uygur volunteer, urged the police to carefully check the identities of adults who brought several children to the railway station or bus stops, as they could well be human traffickers.

BEIJING, Oct. 12 (Xinhuanet) -- Study found that women who took multivitamins may actually be at risk, media reports on Wednsday.Women who took the dietary supplements vitamin B6, folic acid, magnesium, zinc, copper, iron and multivitamins had a higher risk of death than women who did not.The new study, published in the Archives of Internal Medicine, examined more than 38,000 women aged 55 and older who took part in the Iowa Women's Health Study, which started in the mid 1980s. Researchers found the vitamins did nothing to reduce the risk of death and that most supplements have no positive effect on women's health.The study did not distinguish if the women in the study took the vitamins to fight diseases or to maintain health.Vitamin experts say the best way to make sure you are getting all necessary vitamins is to eat a well-balanced diet. The vitamins people take do not  depend on personal preference.

WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.

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.
