BEIJING, Sept. 10 (Xinhua) -- China will start "overall and thorough" safety checks on offshore oil exploration and production to eliminate risks in the wake of oil spills in the country's northern Bohai Bay, the work safety authority said Saturday.The checks, which starts from September 10 to December 10, will be applied to all offshore oil exploration and production, the State Administration of Work Safety said in a circular addressed to oil companies on its website.The companies include China National Petroleum Corporation, China Petrochemical Corporation, China National Offshore Oil Corporation, ConocoPhillips China, Kerr-McGee China Petroleum Ltd., Roc Oil (Bohai) Company, CACT Operators Group, Husky Oil China Ltd., Shanghai Petroleum Co., Energy Development Corporation (EDC) China and Tincy Group Energy, the statement said.The administration urged these enterprises to conduct self-examinations on their offshore fixed and mobile platforms and floating production storage and offloading units, submarine pipelines and onshore oil terminals in two months till November 10. They should file result reports before November 20.The authority's officials, joined by experts, will launch inspections from late November, the statement said. The checks cover well control amid drilling operation, safety management during production, facilities, and management over extreme weather, it added.The order came after the State Council on Wednesday called for strengthened monitoring and management of the marine environment as well as safety checks over the country's ocean oil fields to toughen safety measures and erase potential risks.The decision was made after oil spills at an offshore oil field run by U.S. oil giant ConocoPhillips have polluted more than 5,500 square km of sea water in the Bohai Bay since June.The central government also imposed restricts on new petrochemical projects and ban reclamation projects in the bay for environmental concerns.China has stepped up efforts to explore and materialize offshore resources to seek more dependence of the marine industries as a strategic development move. In its 12th Five-Year Plan, the government advocates greater scientific and systematic utilization of marine resources and coastal areas as energy demand soars.

BEIJING, July 1 (Xinhuanet) -- China must adopt a holistic approach to addressing food safety challenges connected to the risk of contracting infectious diseases from contact with animals, the World Health Organization (WHO) has said. Peter Ben Embarek, food safety officer at WHO's China office, said the country faces risks connected to the need to produce more meat, eggs and milk to feed its growing population. He said the increased production will ramp up the risk of people being infected by food-borne diseases because of poor slaughtering oversight and the absence of proper surveillance and inspection systems. About 50 percent of pigs in China are slaughtered outside of formal facilities without the inspection of veterinarians or food safety officers. He said poorly trained producers have little or no awareness of food safety or the risk of animal diseases being passed on to humans. Such an environment could lead to the emergence of a new pandemic of influenza. During the past 60 years, 30 percent of the 335 new infectious diseases worldwide were transmitted through food, he said. Yet in many parts of China, public awareness remains low about such things. Xu Aixiang, a 35-year-old resident of Rizhao city in Shandong province, prefers to buy live poultry at local markets. Like many of her neighbors, she takes the chickens she buys home to slaughter them. "I get fresher chickens that are better quality this way," she said. "When vendors sell slaughtered chickens, the meat is no longer fresh and may have had water injected into it to make it heavier." But Ben Embarek cautioned that such live-animal markets are high-risk places for the exchange of viruses and diseases between animals and humans. He said simple and cost-effective measures can be taken to improve such markets' hygiene standards, such as the installation of separate areas to keep live poultry away from customers as well as improving air flow and waste management. Several UN agencies, including the WHO and the Food and Agriculture Organization, called on China to adopt an integrated approach to preventing emerging epidemic diseases and maintaining ecosystem integrity at an event themed "One Health" that convened on Wednesday in Beijing. At the gathering, representatives from the Ministry of Health, the Ministry of Agriculture and the Chinese Center for Disease Control and Prevention shared experiences from efforts to mitigate the H5N1 and H1N1 influenza outbreaks in China and said they were committed to working together in the future. Su Jingliang, an associate professor of preventive veterinary medicine at China Agricultural University, said his lab had detected the outbreak of a new type of flavivirus in ducks that led to a significant fall in egg production at farms in Beijing as well as in Hebei, Jiangxi and Shandong provinces. The pandemic was brought under control in March. No cases of humans contracting the disease have been reported so far but Su said he was concerned about the possibility of farmers becoming infected through close contact and long exposure to sick ducks. He said precautionary measures should be taken in cooperation with the Ministry of Health and other government agencies and checks should be run on people who are at high risk. Xu Wei contributed to this story.

HONG KONG, July 19 (Xinhua) -- A gene controlled by male hormone was critical for the growth of liver tumor, leading to a higher incidence of the disease in men than in women, according to the Chinese University of Hong Kong which made the results public on Tuesday.There is a significant gender bias in liver cancer incidence. In Hong Kong, men are three times more likely to develop liver cancer than women. Such phenomenon prompted researchers from the university to carry out a genomic location analysis in liver cancer cells starting from 2008.The researchers discovered, out of 17,000 human genes, that a gene called Cell Cycle-Related Kinase (CCRK) was directly controlled by androgen receptor. They further found that CCRK was critical for the induction of signaling pathway leading to abnormal liver cell growth and tumor formation.The results also reveal that 70 percent of patients with liver cancer were found to produce high levels of CCRK. More importantly, these patients were more likely to have late-stage cancers and lived shorter than those with low CCRK level.Using mouse models, the researchers found that either lowering the level or blocking the signaling pathway of CCRK in liver cancer cells could significantly reduce the tumor growth rate.The study has validated that CCRK is an important gene that has potential to cause liver cancer and the gene can be tested as a new targeted therapy in future.Vice-Chancellor of the university Joseph Sung, who is also team leader of the research project, said the results explained why men have a higher risk of liver cancer than women and helped push ahead with the development of a novel treatment of the disease.The above study results were published online in July in Journal of Clinical Investigation.

LOS ANGELES, June 3 (Xinhua) -- Eating earth may protect the stomach against toxins, parasites and pathogens, a new study suggests.To examine the possible benefits from eating earth, researchers at Cornell University analyzed reports from missionaries, plantation doctors, explorers, and anthropologists to put together a database of more than 480 cultural accounts of geophagy -- the eating of earth.The database includes as many details as possible about the circumstances under which earth was consumed, and by whom. The researchers could then use patterns in the data to evaluate each potential explanation.Studies in the database indicate that geophagy is common even when food is plentiful. Moreover, when people eat dirt they tend to eat only small quantities that are unlikely to fill an empty stomach.The database shows that geophagy is documented most commonly in women in the early stages of pregnancy and in pre-adolescent children. Both categories of people are especially sensitive to parasites and pathogens, according to the researchers.In addition, geophagy is most common in tropical climates where foodborne microbes are abundant. Finally, the database shows that people often eat earth during episodes of gastrointestinal stress.It's unlikely the intestinal problems are caused by the dirt itself because the type of clay people usually eat comes from deep in the ground, where pathogens and parasites are unlikely to contaminate it. Plus, people usually boil the clay before eating it.More study would be helpful to confirm the protection hypothesis, the researchers say, but the available data at this point clearly support it over the other explanations for eating earth."We hope this paper stimulates (more) research," said Sera Young, a researcher at Cornell University and the study's lead author. "More importantly, we hope readers agree that it is time to stop regarding geophagy as a bizarre, non-adaptive gustatory mistake.""With these data, it is clear that geophagy is a widespread behavior in humans ...that occurs during both vulnerable life stages and when facing ecological conditions that require protection."The study is appearing in the June issue of The Quarterly Review of Biology.

CHICAGO, Aug. 25 (Xinhua) -- Gold futures on the COMEX Division of the New York Mercantile Exchange on Thursday bounced off the biggest drop since March 2008, as the weakness in stock market enhanced appeal of gold as a safe-have investment.The most active gold contract for Dec. delivery gained 5.9 U.S. dollars, or 0.3 percent, to 1,763.2 dollars per ounce. The metal suffered on Wednesday the biggest one-day drop since March 19, 2008.Market analysts said that gold extended losses in earlier trading, hit by a margin-requirement increase, but the drop in global stock market gave a push to the metal. Both Dow Jones industrial average and S&P 500 declined on Thursday after a 3-day rise as a government report showed U.S. jobless claims rose last week.Besides, market hearsay went that Germany might be next to get a sovereign-debt downgrade, adding to the positive tone on gold market. German equity market also suffered sharp drop in the day.Many market watchers remained long-term bullish attitude toward gold although they said the precious metal could correct further in the short term. A trader noted that the fundamental factors driving uncertainty and fears are all still there.Expectations are growing that the Federal Reserve Chairman Ben Bernanke would not provide any form of stimulus in a speech scheduled for Friday at a yearly gathering of central bankers in Jackson Hole.Silver for Sept. delivery also rose 1.583 dollars, or four percent, to 40.745 dollars per ounce. Platinum for Oct. delivery lost 3.9 dollars, or 0.2 percent, to 1822.4 dollars per ounce.
