BEIJING, Sep. 13 (Xinhuanet) --Experts have called for a national drug-control system after a nationwide deficit of a life-saving drug, which has lasted at least three months.Doctors at a Beijing hospital said some specialized hospitals, which perform hundreds of cardiac operations every month, have been paralyzed by their lack of protamine sulfate, which is commonly administered after heart surgery to reverse the anticoagulant effects of heparin.The earliest report of a shortage was in Hubei province on July 21. This was followed by reports of shortages in Guangdong, Shandong and Liaoning provinces.The Shandong newspaper, Qilu Evening News, quoted a regional sales manager, surnamed Zhuang, as saying the province had been allocated 150 doses of protamine sulfate after Shanghai No 1 Biochemical and Pharmaceutical Co Ltd recently resumed production of the drug."But its monthly use here is usually 10,000 doses," he said.The Ministry of Health has denied it is responsible for supplies of the drug and passed the buck to the State Food and Drug Administration, claiming the latter is responsible for the supervision of medicines.Shen Chen, head of the publicity office of the State Food and Drug Administration, said he was unaware of the shortage, but said the administration is responsible for the quality of medicines, not the supply."Development and reform authorities oversee the medicines' prices, while the industrial and commercial authorities oversee the storage. The food and drug departments only cover the approval and quality of medicines."Industry insiders said one of the reasons for the shortage was the low profit margin, which discourages companies from mass producing the drug."Some companies can't earn enough to recover their costs, therefore it is almost impossible to maintain their enthusiasm for continuing production," said Lu Guoping, secretary-general of the Shanghai Pharmaceutical Trade Association.Lu said the government should issue policies to prevent future shortages of such medicines to avoid possible nationwide public health incidents.Yi Shenghua, a lawyer at Beijing Yingke Law Firm, said the country should have a unified system to guarantee the normal supply of medicines that are widely used and drug manufacturers should fulfill their responsibilities to society, even though there is no law stipulating they should produce specific medicines.He came up with two ways to deal with the problem of companies only producing profitable drugs."The government can order businesses to manufacture a certain amount of cheap medicines. Or it can offer financial assistance to subsidize cheap, but life-saving medicines."

SINGAPORE, Sept. 7 (Xinhua) -- Singapore scientists have found possible new ways to treat a type of aggressive breast cancer that is unresponsive to current forms of treatment, local broadcaster Channel NewsAsia reported on Wednesday.The team of scientists at the Genome Institute of Singapore ( GIS) and National University of Singapore (NUS), led by GIS senior group leader Qiang Yu, found that the enzyme EZH2 acts by inhibiting genes that stop the growth of tumors in the body.The insights could open the door to developing more effective treatment for fast spreading breast cancers, especially the estrogen receptor-negative breast cancer that is common all over the world.It was also found that through EZH2, cancer is promoted in the body by activating specific genes that impact breast cancer progression and cancer stem cell self-renewal.Yu said the new understanding on how EZH2 works as a cancer- causing gene in breast cancer has important therapeutic implication."The results suggest that small molecule drugs that block enzyme activity of EZH2 may not work for cancers caused by EZH2's activation genes," Yu said.Currently pharmaceutical companies have been developing drugs only to the block EZH2 enzyme activity so that tumor suppressers can perform their protective role in blocking cancer growth.Researchers said the next step would be to develop biomarkers to identify tumors with EZH2.This step would enable better treatment methods, with one of options being the development of therapies that shut down EZH2 completely and not just inhibit its enzymatic function.The findings have been published on the journal Molecular Cell.

LOS ANGELES, July 28 (Xinhua) -- Mainly due to rampant obesity, Americans' life expectancy is one-and-a-half-year shorter than that of Western Europeans on the average, according to a new study published on Thursday.But 40 years ago, Americans could expect to live slightly longer than Europeans, said the study jointly conducted by researchers from University of Southern California (USC), the Harvard School of Public Health and the RAND Corp., a non-profit think tank.In addition to Western Europeans, Americans also die younger than the residents of most other developed nations, according to the study appearing in the July issue of Social Science & Medicine.The life-expectancy disparity, which begins around the age of 50, stems from higher levels of middle-age obesity and obesity-related chronic diseases, such as hypertension and diabetes, said the study.In the first half of the last century, average life expectancy increased by saving more babies, said author Dana Goldman, director of the Schaeffer Center for Health Policy and Economics at the USC."But now it is reduction in mortality among the elderly, rather than the young, that propels increases in life expectancy," he said. "The question is whether 'being American' is an independent mortality risk factor."If 50-year-old U.S. adults could be as healthy as Europeans, it could save Medicare and Medicaid 632 billion dollars by 2050, the study said.Though the transition to better health initially raises expenditures, the researchers estimate that by 2050 healthcare savings from health improvements among the middle age could total more than 1.1 trillion dollars."The international life expectancy gap appears much easier to explain than gaps within countries: there is no American-specific effect on longevity beyond differences in disease at age 50," said Darius Lakdawalla, an associate professor in the USC School of Policy, Planning and Development.

UNITED NATIONS, June 9 (Xinhua) -- China on Thursday called for governments, organizations and individuals to take active actions, enhance solidarity and establish joint prevention and treatment mechanism to deal with AIDS.Yin Li, vice Health minister of China made the remarks as he addressed the United Nations High-Level Meeting on HIV/AIDS held here."As a responsible developing country, the Chinese government has actively fulfilled its commitments in achieving universal access to AIDS prevention and treatment, eliminating social discrimination, and ensuring rights to prevention, treatment and care of people living with HIV/AIDS and their families," he said.Thanks to the efforts over the years, the spread of AIDS epidemic in China has slowed down, the morality rate considerably decreased and life quality of people with HIV/AIDS has significantly improved, Yin added.In order to achieve the goal of zero new HIV infections, zero discrimination and zero AIDS-related deaths defined by the joint UN Program on HIV/AIDS (UNAIDS), China called for all countries, organizations and persons to be mobilized, further enhance solidarity and clearly define responsibilities and establish a joint prevention and treatment mechanism.Yin said that in the face of the common challenge of HIV/AIDS, the developed and developing countries must assume shared responsibilities."The developed countries should further provide developing countries with generous, unconditional financial and technical support. The developing countries should give the same priority to AIDS control as economic development, explore the models of prevention and treatment consistent with their national conditions, " he said.In addition, the private sector and relevant organizations should assume more responsibilities. On one hand, efforts should be made to mobilize more resources in better implementing prevention, treatment and care measures; on the other hand, multinational drug manufactures should reduce drugs and testing equipment prices through technology transfer, contract manufacturing and reduction of monopoly profits in order to provide universal access to treatment services, according to Yin.Yin stressed that the Chinese government would strengthen its working mechanism, enhance coordination across sectors and participation by the entire society, continue to actively participate in global fight against AIDS, assume its responsibilities and obligations so as to make contribution to achieving the goal of global AIDS control.

BERLIN, June 6 (Xinhua) -- The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in Europe.According to a statement issued by the Agriculture Ministry of the Lower-Saxony state, 23 of 40 samples concerning the suspected sprouts from a market garden in the state have tested negative, and further tests are still pending."Based on the initial findings in tests of some of the samples, especially the seeds, we assume that intensive analytical efforts are needed to prove that the suspected pathogen is really there," the statement said.Beansprouts and salad sprouts are seen in this picture illustration taken in Berlin June 6, 2011.  The German authorities said on Monday that Germany's first sample tests of the allegedly contaminated bean sprouts have found no E. coli strains that have sickened more than 2,000 people in EuropeLower-Saxony's Agriculture Minister Gert Lindemann said Sunday that a market garden in the rural district of Uelzen had provided a connection "involving all the main outbreaks" of the disease.Restaurants and food outlets of almost all E. coli-affected areas had received shipments of sprouts directly or indirectly from the company, state officials said.The German authorities have been racing to track down the source of the pathogen since the outbreak, which has infected people in 12 countries, all of whom had once traveled in northern Germany.More than 600 of those infected have developed Hemolytic Uremic Syndrome, a potentially deadly complication attacking the kidneys.The E. coli source was first thought to be cucumbers from Spain, which has caused huge loses for Spain farmers. However, this conclusion was overthrown by laboratory tests in Hamburg later.
