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.

NEW YORK, Dec. 1 (Xinhua) -- New York City Mayor Michael Bloomberg announced on Thursday a new recommendation that doctors offer every person with an HIV diagnosis antiretroviral treatment to help them live longer and prevent transmission.This marks a change from the current practice that treatment only be offered to those who show signs of damage to their immune systems, said the mayor during the annual World AIDS Day commemorative ceremony at Gracie Mansion. "Over the past ten years HIV diagnoses and deaths in New York City have seen a dramatic decline," said Mayor Bloomberg. "Steady progress in our fight against HIV has turned what used to be a death sentence into a disease that can be prevented and, with antiretroviral therapy, managed.The annual death toll from HIV in the city is down by more than a third: 933 deaths in 2009Despite this progress, however, more than 110,000 people in New York City are infected with HIV, more than in any other U.S. city and about 75 percent of all cases in the New York State.Figures from the New York City Health and Hospitals Corporation (HHC) showed that HHC has tested more than one million New Yorkers for HIV since 2005 when the public hospitals and health centers began offering HIV screening as a routine part of medical care for patients aged 13 to 64.

SEOUL, Nov. 28 (Xinhua) -- Samsung Electronics, the world's second-largest manufacturer of mobile phones, said Monday that it launched its latest smart mobile gadget Galaxy Note in South Korea in a bid to take the lead in a new phase of the mobile phone market.The Galaxy Note, which was first introduced in September at IFA 2011, the consumer electronics fair held in Berlin, was Samsung's latest Galaxy lineup, combining the portability of a smartphone with the larger screen of a tablet computer, according to Samsung.The device ensured portability and grip with 9.65-millimeter thin, 182 grams in weight and a rounded back design, while featuring a 5.3-inch super active-matrix organic light-emitting diode (AMOLED) display.The function of "S Pen," or a digital pen, was added to the device in a bid to enable users to draw, paint and crop images by writing on the screen, Samsung said.Featuring Android's 2.3 Gingerbread platform, the gadget was powered by a 1.5-gigahertz dual core processor supplemented with fourth generation (4G) long term evolution (LTE) network service."Galaxy Note is a revolutionary product opening a new category in the market.

SHANGHAI, Oct. 14 (Xinhua) -- The government of Shanghai, the largest metropolis in eastern China, plans to require users of matchmaking websites to register their real names, a move to make those websites a more honest and ordered community, authorities said on Friday.The environment of the matchmaking websites is chaotic and the anonymity afforded by the Internet opens the door to cybercrimes such as fraud, said Zhou Juemin, chairperson of Shanghai Matchmaking Organization Administration Association.Officials with the Shanghai Civil Affairs Bureau said people who put up personal ads in newspapers may also be requested to use their real names in the future.China's matchmaking industry has been thriving in recent years as the country is witnessing an increase in the number of singles. Statistics from the All-China Women's Federation shows China currently has around 180 million singles.

WASHINGTON, Nov. 14 (Xinhua) -- Vitamin D levels are significantly lower in patients with recurrent inflammatory spinal cord disease, according to a study published online Monday in Archives of Neurology.Vitamin D is a steroid vitamin that promotes the intestinal absorption and metabolism of calcium and phosphorus. In recent years, low levels of vitamin D have been linked to a variety of autoimmune conditions, including multiple sclerosis (MS). However, the importance of vitamin D in monophasic or recurrent non-MS spinal cord diseases including transverse myelitis and neuromyelitis optica is unknown, according to background information in the article.Transverse myelitis (TM) is a disease of the spinal cord in which there is involvement of the myelin sheath that protects nerve fibers; symptoms include back pain and weakness in the legs. Neuromyelitis optica (NMO) is a disease of the central nervous system that affects the optic nerves and spinal cord.Maureen Mealy, of Johns Hopkins University and colleagues investigated the association between low serum vitamin D levels and recurrent spinal cord disease. They analyzed data on vitamin D levels among 77 patients with monophasic (having only one phase or stage) and recurrent inflammatory diseases of the spinal cord, adjusting for season, age, sex, and race. The study found that vitamin D levels were significantly lower in patients who developed recurrent spinal cord disease."Our findings suggest that there may be an association between lower total 25-hydroxyvitamin D levels in patients with recurrent TM/NMO/ spectrum disorders as compared with their counterparts with monophasic disease," the authors report. They suggest that future studies are needed to further assess the relationship between vitamin D and recurrent spinal cord disease.
