BEIJING, March 17 (Xinhuanet) -- A new study has shown that gene therapy can reduce symptoms in patients with Parkinson's, media reports said Thursday.The study, published in the journal Lancet Neurology, is the first to show positive results in a test of gene therapy against a sham operation in 45 U.S. Parkinson's patients.The treated group showed a 23.1 percent improvement on a scale of Parkinson's symptoms six months after treatment, compared to a 12.7 percent improvement for patients who received sham surgery, according to the published research."Gene therapy is no longer just a theory," said Michael Kaplitt, a neurosurgeon at New York-Presbyterian Hospital and Weill Cornell Medical Center, and one of the study authors. "We are getting much closer to a reality where this treatment can be offered to patients."In patients with Parkinson's disease, their brains get overactive after losing the normal supply of a chemical called GABA. The new treatment, gene therapy, works by inserting billions of copies of a gene into patients' brains that helps them produce more GABA.Kaplitt said the results might spur similar treatments for other brain disorders like Alzheimer's, epilepsy and depression.

BEIJING, May 5 (Xinhua) -- A Chinese official has vowed to take every possible measure to ensure food safety in the country, saying the government has decided to launch national overhauls this year on sectors including milk products, cooking oil, health foods, meat and alcohol.Zhang Yong, director of the executive office of the food safety commission under the State Council, or Cabinet, said in an interview with Xinhua that the food and drinks in these five sectors are consumed in enormous quantities each day and they will do great harm and have an extensive social impact if a problem arises.Through special campaigns to overhaul these five sectors and by solving the most prominent problems, the government aims to accumulate experiences and create administrative systems in a bid to prevent food safety incidents and raise the overall level of food safety, Zhang said.The central government initiated a prolonged and stringent fight against the illegal use of additives in food last month, detailing measures to intensify supervision, upgrade safety limits, and increase penalties for violators.Vice Premier Li Keqiang warned of the great harm from illegal additives in food at a high-profile national meeting last month, promising a "firm attitude, iron-hand measures and more efforts" in dealing with the problem.Zhang Yong admitted "China is in a period when food safety incidents are likely to arise" since the country's food industry is on a fast track for development and a large number of food producers and catering operators are running their businesses in a small-scale or scattered way."It makes it more difficult for the government departments to conduct supervision on food quality and safety," Zhang said."We will take every possible measure to consolidate the feeble foundation to ensure food safety and curb food safety incidents as soon as possible," he said.According to Zhang, the government will also make efforts to improve supervision and emergency handling capabilities, raise the credibility and personnel quality of the involved enterprises, and severely punish violators.The Chinese government made the moves after a series of food safety scandals emerged despite the authorities' efforts to revamp the country's food industry. They included steamed buns dyed with unidentified chemicals, the use of "lean meat powder", also known as clenbuterol, a kind of fat-burning drug, as well as the use of illegal cooking oil known as "gutter oil."

SANAA, Feb. 6 (Xinhua) -- In response to earlier reports that a Chinese-flagged commercial ship was hijacked by Somali pirates off Yemeni coast, the China Maritime Search and Rescue Center (MSA) said Sunday that the ship has never been hijacked, and is now sailing safely with escort of the Chinese anti-piracy navy fleet.Both the "Tien Hau" ship, which was registered in Hong Kong, China, and its 22-member crew, are safe, a MSA official confirmed to Xinhua over the phone. The center contacted the ship to make sure it was safe, he added.The ship had been followed by a suspicious boat for a while, but it was never attacked or hijacked, the official said.Earlier, Yemeni Interior Ministry had said the ship was hijacked by pirates some 20 kilometers off the Yemeni island of Al-Tair off the city port of al-Hudaida, and was heading to Somali coast.The Gulf of Aden is considered as one of the world's most dangerous waters because of rampant piracy.

CHENGDU, Jan. 30 (Xinhua) -- Over the crowds of holiday shoppers in China's big stores this Spring Festival lingers an atmosphere of suspicion.With charges of price deception hanging over the big chains of Carrefour and Wal-Mart and local authorities moving to levy fines, many Chinese -- normally averse to be pinching pennies during the Lunar New Year -- are checking their receipts at the tills.The New Year, which falls on Feb. 3 this year, is normally a time of largesse and excess -- all the more reason why many shoppers feel so betrayed.Customers can be seen recording label prices in notebooks or calculating their final bill on their mobile phones as they walk the aisles.At outlets of Carrefour and Wal-Mart in cities such as Beijing, Shanghai and Chengdu, the check out queues have grown as customers doublecheck prices at the tills."I would never have imagined global firms would do this intentionally and I have to be cautious," said a woman surnamed Wang, after shopping at a foreign-owned supermarket in Chengdu, southwest China's Sichuan Province.With three bulging shopping bags, Wang stood next to the check out to calculate the final bill: "We buy a lot for the New Year celebrations, so I have to be more careful."The official weeklong Spring Festival holiday, which starts Wednesday, is China's closest equivalent to the West's Christmas shopping season, with generous gifts of food, tobacco, liquor and other presents for family and friends.According to the Ministry of Commerce, China's retail sales hit 340 billion yuan (49.8 billion U.S. dollars) during the Spring Festival holiday week last year."The deceptive pricing practices of the two foreign-funded supermarket giants were a total scandal," said Wang. "I have to be careful with the prices and the labels.""Cheating by the supermarkets is the same as stealing. I might have suffered losses as I don't normally check receipts," said a Chengdu man surnamed Li.Wal-Mart (China) Investment Co., Ltd. offered a "sincere apology" to affected customers on Thursday. The company has been cooperating with investigations into the cheating. It has also launched inspections of stores nationwide.Chen Bo, spokesperson for Carrefour China, said Sunday that Carrefour sincerely apologized to Chinese customers for inconvenience and losses caused by pricing irregularities.Carrefour would refund customers five times the difference between the price charged and that on the label. The refund policy would be implemented at Carrefour's 182 outlets in China.The issue is continuing to smoulder on the Internet, with websites asking people to write in with "your experiences of price cheating by the Carrefour."A survey by Sohu, one of China's major web portals, had resulted late Sunday in 8,451 of 9,507 respondents saying they "would not go to Carrefour as it is blacklisted for price cheating.""Carrefour will further strengthen price label management and improve service quality to gain the support and confidence of Chinese customers," said Chen Bo.Carrefour had drawn up short and long-term measures to solve the price label issue, including price inspections, improving and upgrading the price label system, and comprehensive staff training."We will have our special control group conduct frequent and wide-ranging internal price inspections," Chen said.The National Development and Reform Commission (NDRC), China's top economic planner and price regulator, said Wednesday that some Carrefour and Wal-Mart stores in China were involved in deceptive pricing practices.The NDRC ordered local pricing authorities to urge stores to correct their wrongdoing, and pay fines five times the illegal income. It also urged authorities to step up price checks ahead of the Spring Festival.

CANBERRA, April 1 (Xinhua) -- People who share bongs to smoke marijuana may be at risk of contracting pulmonary tuberculosis (TB) , Australian medical researchers warned on Friday.Dr Michael Hayes and Dr Susan Miles from Calvary Mater Hospital in Newcastle of Australia conducted the research, which centered on three recent TB cases in New South Wales.TB is caused by the bacteria Mycobacterium tuberculosis, which can be contracted by breathing in air droplets coughed from an infected person.The research suggested a link between active TB cases and shared bongs, which is the water pipes commonly used in marijuana smoking.According to Dr Hayes, the three young patients were regular or heavy cannabis users, and more recently there has been a fourth person in the region with similar characteristics had been diagnosed with TB.He said although the three initial cases were not related, there was concern about the high rate of positive contacts among people who had shared bongs with the active cases."Smoking marijuana is a cough-provoking activity and it is usually conducted in a confined environment that is conducive to the spread of the organism," he told Australia Associated Press.
