BEIJING, Feb. 12 (Xinhua) -- The Chinese government has reiterated a strict ban on hepatitis B tests during pre-employment physical examinations as many companies reportedly violated rules to require hepatitis B tests for job applicants.In a statement released Saturday, the Ministry of Health said that no health institutions are allowed to provide hepatitis B checks as part of pre-employment physical tests regardless of whether the examinees provide consent or not.On Feb. 10, 2010, the Ministry of Health, the Ministry of Education and the Ministry of Human Resources and Social Security jointly issued a circular demanding the cancellation of the hepatitis B tests during the health checks for school enrollment and employment nationwide.However, according to a survey released this week, which was conducted by the non-profit Beijing Yirenping Center, some 61.1 percent of the 180 state-run companies surveyed included hepatitis B checks in their pre-employment physical examinations.More surprisingly, 63 companies said that they would never consider hepatitis B carriers for a job or were reluctant to hire such people.Yu Fangqiang, the principal of the Yirenping Center, said that such violations mainly resulted from light punishment for violations and some health institutions' desire for profits.According to the survey, employers would only be fined between thousands to tens of thousands of yuan if they lose their lawsuits for bias against hepatitis B carriers.Meanwhile, a worker will spend a lot of time, energy and money to file a lawsuit and collect evidence in order to win.Liu Xiaonan, an associate professor with the China University of Political Science and Law, called on the government to hammer out a particular law and set up a special committee to investigate discrimination cases in order to ensure the rights of workers.In the statement released Saturday, the health ministry also ordered a careful investigation of all cases of hepatitis B discrimination, and promised that violators would be exposed and punished in accordance with laws and regulations.Medical tests show that hepatitis B virus can only be transmitted from mother to child during childbirth or by contact with the blood or other body fluids of an infected person.

LOS ANGELES, March 18 (Xinhua) -- The moon will move closer to Earth than it has been in more than 18 years Saturday night, space. com reported on Friday.On Saturday afternoon at 3 p.m. Eastern Daylight Time (1900 MGT) , the "supermoon", as dubbed by some observers, will arrive at its closest point to the Earth in 2011: a distance of 221,565 miles ( 356,575 kilometers) away, and only 50 minutes earlier, the moon will officially be full, the report said.At its peak, the supermoon may appear 14 percent larger and 30 percent brighter than lesser full moons (when the moon is at its farthest from Earth), weather permitting, said the report.Yet to the casual observer, it may be hard to tell the difference, according to the report.Scientists say it is a fluke of orbital mechanics that brings the moon closer to Earth.The supermoon will not cause natural disasters, such as the Japan earthquake, NASA scientists say.In December 2008, there was a near-supermoon when the moon turned full four hours away from its perigee - the point in its orbit that is closest to Earth. But this month, the full moon and perigee are just under one hour apart, promising spectacular views, depending on local conditions, the report said.

WASHINGTON, May 11 (Xinhua) -- Researchers at Brigham and Women 's Hospital (BWH), a teaching affiliate of Harvard Medical School, have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung. This research will be published Thursday in the New England Journal of Medicine."This research describes, for the first time, a true human lung stem cell. The discovery of this stem cell has the potential to offer those who suffer from chronic lung diseases a totally novel treatment option by regenerating or repairing damaged areas of the lung," said the study's corresponding author Piero Anversa, who is also director of the Center for Regenerative Medicine at the hospital.Using lung tissue from surgical samples, researchers identified and isolated the human lung stem cell and tested the functionality of the stem cell both in vitro and in vivo. Once the stem cell was isolated, researchers demonstrated in vitro that the cell was capable of dividing both into new stem cells and also into cells that would grow into various types of lung tissue. Next, researchers injected the stem cell into mice with damaged lungs. The injected stem cells differentiated into new bronchioles, alveoli and pulmonary vessel cells which not only formed new lung tissue, but also integrated structurally to the existing lung tissue in the mice.The researchers define this cell as truly "stem" because it fulfills the three categories necessary to fall under stem cell categorization: first, the cell renews itself; second, it forms into many different types of lung cells; and third, it is transmissible, meaning that after a mouse was injected with the stem cells and responded by generating new tissue, researchers were then able to isolate the stem cell in the treated mouse, and use that cell in a new mouse with the same results."These are the critical first steps in developing clinical treatments for those with lung disease for which no therapies exist. Further research is needed, but we are excited about the impact this discovery could have on our ability to regenerate or recreate new lung tissues to replace damaged areas of the lungs," said Joseph Loscalzo, chair of the Department of Medicine at BWH and co-author.

BEIJING, March 22 (Xinhuanet) -- NASA scientists are testing its next-generation Mars rover, which will land on Mars next year, under extreme conditions at space-simulation chamber in California, media reports said Tuesday.Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., say they've installed the Curiosity rover in a space-simulation chamber that can mimic the environment the probe will encounter on Mars.  After the chamber's large door was sealed last week, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius, and a bank of powerful lamps simulated the intensity of sunshine on Mars.After the test period, the rover along with other portions of NASA's Mars Science Laboratory spacecraft including the cruise stage, descent stage and backshell -- part of protective covering -- will be shipped to the Kennedy Space Center for final preparation for the launch window from Nov. 25 to Dec. 18, 2011. Curiosity will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.

BEIJING, Feb. 5 (Xinhua) -- Lending to China's small and medium-sized enterprises (SMEs) rose faster than loans to large enterprises last year, according to the People's Bank of China (PBOC), the central bank.Outstanding loans to small enterprises by banks and financial institutions jumped 29.3 percent year on year to 7.55 trillion yuan (1.15 trillion U.S. dollars) in 2010, while loans to medium-sized enterprises stood at 10.13 trillion yuan, up 17.8 percent, said the PBOC.Outstanding loans to large enterprises rose 13.3 percent to 13.42 trillion yuan, highlighting the government's efforts to optimize the loan structure, the PBOC said.About 99 percent of Chinese enterprises are SMEs which contribute 60 percent of the country's gross domestic product.Financing has long been difficult for Chinese SMEs as banks prefer to lend to big companies, particularly reputable state-owned enterprises.The government has moved to help SMEs get finance by differentiating the reserve requirement ratio for the Rural Credit Cooperative, the major lender to SMEs, and encouraging innovation in SME bond issuance.In July last year, the PBOC asked financial institutions to establish independent criteria for approving loans to SMEs and to improve efficiency in processing SME loan applications.The PBOC said SME loan growth would continue to accelerate this year.
