BEIJING, Nov. 24 (Xinhua) -- In response to public suspicion stoked by recent dumpling contamination scandals, China's Ministry of Health on Thursday said the new food safety standard for flash-frozen dumplings did not show signs of leniency.The Ministry introduced the new food safety standard on flash-frozen dough or rice products on Thursday.The Ministry has been accused of loosening scrutiny over a disease-generating bacteria in such foods, staphylococcus aureus, or golden staph, which can cause various diseases, including pneumonia and sepsis, and is sometimes life-threatening.The controversy became particularly relevant after several major brands of frozen dumplings have been successively recalled in recent months.In October, a Henan-based company, Zhengzhou Sinian Food Co., Ltd, confirmed the contamination of golden staph in its flash-frozen seafood- and pork-stuffed dumplings.Frozen dumplings made by Hong Kong-based manufacturer Wanchai Ferry were found to contain golden staph in November, and some of its products have been pulled from shelves.The previous standard provided that no golden staph should be tested in such food, while the new one gives a quantitative restriction that the volume of the bacteria should be no more than ten to the fourth degree.Liu Xiumei, a food safety expert with the Chinese Center for Disease Control and Prevention, said at the press conference held by the health ministry that such bacteria becomes inactivate after the food is boiled for a few seconds, and it takes a volume of ten to the fifth degree to generate toxicity.The previous standard could only serve as a general provision due to the lack of quantitative microbiological testing back when it was introduced, Liu said, stressing that the new standard is not a sign that the Ministry has gone soft on bacterial contamination of relevant foods.The new standard will come into effect starting Dec. 21, 2011.

XIAMEN, Dec. 26 (Xinhua) -- The three-decade achievements of the Xiamen Special Economic Zone have shown that China has made the right decision to set up special economic zones (SEZs), President Hu Jintao said Monday.Hu made the remarks in a congratulatory letter to a gala held Monday in southeastern Fujian province's city of Xiamen, which is celebrating the 30th founding anniversary of its special economic zone.Over the past 30 years, the Xiamen Special Economic Zone has made marked socio-economic progress, made significant changes in people's lives, and served as a pilot area for the country's reform and opening-up and socialist modernization, Hu said.The Xiamen Special Economic Zone has made a unique contribution to promoting cross-Strait economic and trade cooperation as well as culture and personnel exchanges, Hu said in the letter.Hu also urged the economic zone to further enhance the capability of independent innovation, ensure and improve people's well being, strengthen and make innovations in social management, and better serve the peaceful development of the cross-Strait relationship.He Guoqiang, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, attended and addressed the gala.In his speech, He said the economic zone should develop high-end manufacturing business and a modern service industry, while speeding up the establishment of a market-oriented technology innovation system that integrates production with scientific research.The economic zone needs to make greater efforts in energy saving and emissions reduction as well as environmental protection by greatly developing a green and recycling-based economy, according to He.He also said that the economic zone should exert itself to increase the income of rural and urban residents, especially low-income residents, and meet people's basic requirements in terms of education and culture, employment, medical services and housing."Reasonable appeals of the people should be addressed, and behavior that undermines people's interests should be resolutely rectified," He said.In addition, He expects the Xiamen Special Economic Zone to thoroughly implement the cross-Strait Economic Cooperation Framework Agreement (ECFA) and further explore and enhance cooperation in finance and logistics with Taiwan, He said.The economic zone should also strengthen the development of direct flights, customs clearance and ports in order to facilitate direct exchanges across the Taiwan Strait, according to He.He also met with representatives of Hong Kong, Macao and Taiwan residents and overseas Chinese, who attended the gala.He said people from all walks of life in Hong Kong, Macao and Taiwan have long been active in investing, financing education and alleviating poverty in Fujian.They have not only shared the opportunities that the country's reform and development have brought forth and expanded their own enterprises, but also greatly boosted the country's socio-economic progress, He said."You are witnesses, participants and beneficiaries of the reform and opening up," He said to these representatives.The Xiamen Special Economic Zone is one of the four earliest SEZs set up after China initiated the reform and opening up in 1978. In 1984, it was expanded from the initial 2.5 square kilometers to 131 square kilometers. Last year, it was extended to span the entire city.

BEIJING, Nov. 28 (Xinhuanet) -- Scientists in Canada have raised a prospect of reversing Alzheimer's disease by deep brain stimulation, according to media reports Monday.The technique here is known as deep brain stimulation -- applying electricity directly to regions of the brain. It has been used in tens of thousands of patients with Parkinson's as well as having an emerging role in Tourette's Syndrome and depression.The study at the University of Toronto took six patients with the condition. Deep brain stimulation was applied to the fornix -- a part of the brain which passes messages onto the hippocampus.Lead researcher Prof Andres Lozano said you would expect the hippocampus to shrink by five per cent on average in a year in patients with Alzheimer's.After 12 months of stimulation, he said one patient had a five per cent increase and another had an eight per cent increase.Prof Lozano told BBC: "This is the first time that brain stimulation in a human being has been shown to grow an area of your brain.""It was an amazing finding for us," he said.The findings were presented at the Society for Neuroscience conference in November but they have yet to be published in an academic journal.To test whether this is really working, rather than being a fluke result, the researchers are going to perform a larger trial.

BEIJING, Nov. 7 (Xinhuanet) -- A huge asteroid will pass closer to Earth than the moon on Tuesday, but experts say there is no cause for alarm.Asteroid 2005 YU 55 will pass about 300-thousand kilometers from the earth. The giant space rock is about 400 meters in diameter. The close encounter will occur at 23:28 Greenwich Mean Time. Computer models showing the asteroid’s path for the next 100 years show there is no chance it will hit Earth during that time.Previous studies show the asteroid is what is called a C-type asteroid that is likely made of carbon-based materials and some silicate rock.

WASHINGTON, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.
