HARBIN, March 2 (Xinhua) -- A therapeutic apparatus to treat Parkinson's disease has been developed in northeast China's Heilongjiang Province, according to the provincial science and technology department. It is a worldwide breakthrough in treating the disease with transcranial magnetic stimulation, concluded an expert panel with the Heilongjiang Provincial Department of Science and Technology.The team said it came to the conclusion after evaluating technical documents and clinical test results Monday.This is the first time that transcranial magnetic stimulation has been adopted to treat Parkinson's disease, said Sun Zuodong, chairman of Aobo Medicine Apparatus Co., Ltd. (AMA), the developer based in the provincial capital Harbin.Transcranial magnetic stimulation is a noninvasive method which causes depolarization in the brains' neurons so as to restore the functions of brain nerves.The apparatus consists of three parts, namely brain wave stimulator, field effect cap and multiplier, said Sun.Clinical tests over more than 100 patients showed that the apparatus had a 70 percent success rate in reducing the disease's symptoms, according to Wang Aili, planning manager of AMA.The new equipment will help generation of dopamine, the reduction of which within the brain caused the disease, said Wang Weixiang, a consulting doctor with the Heilongjiang Provincial Rehabilitation Hospital.Parkinson's disease is a disorder of the neural system, which leads to limb tremors and difficulty in walking and other movements.China has 2 million patients suffering from Parkinson's disease, mostly people over the age of 50, and the number is increasing by 100,000 annually, said Dr. Wang.

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.

HARARE, Feb. 11 (Xinhua) -- Chinese Foreign Minister Yang Jiechi on Friday called on the West to lift sanctions they imposed on Zimbabwe while Zimbabwean President Robert Mugabe applauded the Asian giant for its continued political and economic support.Addressing journalists soon after meeting Zimbabwe President Mugabe, Yang, who is on a two-day visit, said Zimbabweans and other African people have a right to choose their own development path."We believe there should be the lifting of sanctions by certain countries. We think that is the voice of the Zimbabwean people and that is also the view of all the parties concerned here in Zimbabwe," Yang said, adding that no country has a right to dictate to another."We believe all nations should respect each others sovereignty and territorial integrity," he said."China believes that Africans have the right to choose their own way of development as they are the masters of the African continent. All others are just guests," he said.Yang said that China appreciates assistance from Africa and would also continue to reciprocate the support.Addressing the Chinese delegation earlier, Zimbabwean President Mugabe said the West continues to persecute Zimbabwe through sanctions for the decision the county took to empower its people through land.He said the imposition of sanctions was despite the fact that Zimbabwe and Britain had agreed that the former would redistribute the land while the latter would compensate affected farmers."The Western countries have imposed sanctions on us for taking our land although we had discussed this in 1979. That is what started the problem," Mugabe said.Mugabe said Britain had since turned to political reasons such as human rights, democracy and rule of law to justify continued sanctions imposed on Zimbabwe.He applauded continued cooperation between China and Zimbabwe which dates back to the struggle for independence.Meanwhile, China extended a 50 million yuan (7.5 million U.S. dollars) grant to Zimbabwe.Yang and his Zimbabwean counterpart Simbarashe Mumbengegwi signed the agreement on behalf of their countries.In his meeting with Mumbengegwi, Yang who described Zimbabwe as a "brother" said the two countries had identified areas for further cooperation such as infrastructure, agriculture, water conversation and personnel training.

BEIJING, Feb.11 (Xinhua) -- Representatives from different sectors have given feedback on drafts of the government work report and China's economic and social development blueprint for the next five years, the State Council, China's cabinet, said Friday.Premier Wen Jiabao chaired five seminars from Jan. 20 to 27, at which representatives of various sectors of society were invited to voice their views on the documents, according to a State Council statement.The 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review at the plenary session of the National People's Congress (NPC), China's top legislature, in March.Experts from social economic organizations along with those from science and technology, education, health, culture and sports circles attended the meetings, as well as members of non-communist parties.Participants at the seminars agreed on the framework and main content of the documents. They also gave some suggestions and proposed a couple of revisions to the report and the development plan.Most suggestions focused on China's economic restructuring, income distribution adjustment, modern agricultural development, scientific innovation, reform of the yuan exchange rate formation mechanism, property market regulation and affordable housing construction, and further improvement in education and medical care system.The forums also invited 11 grass-roots representatives, including farmers, technicians, and owners of small businesses, who raised suggestions to boost farmland irrigation construction, train more technicians, and help with the development of small and medium enterprises.Wen said the feedback will be "of great help" when revising both the government work report and 12th five-year plan, as well as to the work of the government.

WASHINGTON, April 20 (Xinhua) -- Those childhood music lessons could pay off decades later -- even for those who no longer play an instrument -- by keeping the mind sharper as people age, according to a preliminary study published by the American Psychological Association (APA).The study recruited 70 healthy adults age 60 to 83 who were divided into groups based on their levels of musical experience. The musicians performed better on several cognitive tests than individuals who had never studied an instrument or learned how to read music, according to the research findings published Wednesday online in the APA journal Neuropsychology."Musical activity throughout life may serve as a challenging cognitive exercise, making your brain fitter and more capable of accommodating the challenges of aging," said lead researcher Brenda Hanna-Pladdy, a clinical neuropsychologist at the University of Kansas Medical Center. "Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older."The three groups of study participants included individuals with no musical training; with one to nine years of musical study; or with at least 10 years of musical training. All of the participants had similar levels of education and fitness and didn' t show any evidence of Alzheimer's disease.All of the musicians were amateurs who began playing an instrument at about 10 years of age. More than half played the piano while approximately a quarter had studied woodwind instruments such as the flute or clarinet. Smaller numbers performed with stringed instruments, percussion or brass instruments.The high-level musicians who had studied the longest performed the best on the cognitive tests, followed by the low-level musicians and non-musicians, revealing a trend relating to years of musical practice. The high-level musicians had statistically significant higher scores than the non-musicians on cognitive tests relating to visuospatial memory, naming objects and cognitive flexibility, or the brain's ability to adapt to new information.The brain functions measured by the tests typically decline as the body ages and more dramatically deteriorate in neurodegenerative conditions such as Alzheimer's disease. The results "suggest a strong predictive effect of high musical activity throughout the lifespan on preserved cognitive functioning in advanced age," the study stated.Half of the high-level musicians still played an instrument at the time of the study, but they didn't perform better on the cognitive tests than the other advanced musicians who had stopped playing years earlier. This suggests that the duration of musical study was more important than whether musicians continued playing at an advanced age, Hanna-Pladdy says."Based on previous research and our study results, we believe that both the years of musical participation and the age of acquisition are critical," Hanna-Pladdy says. "There are crucial periods in brain plasticity that enhance learning, which may make it easier to learn a musical instrument before a certain age and thus may have a larger impact on brain development."The preliminary study was correlational, meaning that the higher cognitive performance of the musicians couldn't be conclusively linked to their years of musical study. More research is needed to explore that possible link.
