JINAN, Oct. 24 (Xinhua) -- Chinese scientists have made a breakthrough that could lead to more effective treatments for leprosy.A team from Shandong Provincial Institute of Dermatology and Venereology in east China has identified two new risk variants near IL23R and RAB 32 genes that are responsible for the disease, according to a report published online Monday in the scientific journal Nature Genetics.Knowing that the two gene variants influence susceptibility to leprosy could allow doctors to diagnose the disease in sufferers earlier in its outset, as well as to develop new treatments. A genetic database could now be built up to predict those people particularly susceptible to leprosy, said Zhang Furen, the leader of the research team.The study involved more than 10,000 samples being taken from leprosy sufferers and healthy test subjects and analysed.Leprosy is a chronic nerve-killing disease that leads to problems with patients' skin, feet, hands, legs and eyes. More than 200,000 newly-contracted leprosy cases are reported worldwide every year, and China has around one tenth of the world's sufferers. 

BALI, Indonesia, Nov. 19 (Xinhua) -- Chinese Premier Wen Jiabao said on Saturday that an immediate task for East Asian nations in the face of the global financial crisis was to maintain continuous, rapid development of the region's economy.Addressing the 6th East Asia Summit, Wen said East Asian nations should provide momentum for the world economy's robust, sustainable and balanced development."We should continue to strengthen cooperation and the summit should play a strategic role in this regard," he said.Wen put forward a five-point proposal for boosting the regional economy:First, coping with the international economic and financial crisis should continue to be regarded as a priority, he said.East Asian nations should implement appropriate fiscal and monetary policies in accordance with their national conditions, shore up market confidence, and enhance coordination in the macro-economic policy and financial cooperation.Second, Wen said the region should earnestly carry out and improve agreed free trade arrangements, steadily advance the building of new free trade areas, and further open markets.The Chinese premier called on East Asian nations to counter protectionism and properly handle international trade frictions.Third, the region should encourage expansion of investment and increase investor confidence, he said.It should boost the inner drive for its development through such ways as industrial transfer and regional interconnection, Wen said.Fourth, he called for prioritizing sustainable development as a long-term cooperative goal, stronger cooperation in key fields, help for East Asian countries to transform their economic development model, and intensified cooperation in such areas as energy-saving, environmental protection, education and disaster control, so as to enhance development potential.His final point urged overcoming challenges brought by non-traditional security threats to create a better environment for development, and strengthening cooperation in the fields of information exchange, capacity building and emergency response.Wen said that, as a strategic forum, the EAS facilitated mutual understanding and cooperation between East Asian nations."Under the new situation, we should continue to regard the Association of Southeast Asian Nations (ASEAN) as the dominant power of cooperation at the summit and make efforts to seek and expand interest junctions," he said.China was willing to work with all sides to make the summit more fruitful and benefit more countries and peoples, the Chinese premier said.Echoing Wen's remarks, participants at the summit said under the current international political and economic situation, East Asian cooperation should continue to wield the influence of ASEAN domination and the existing mechanism to intensify mutual support and coordination, and deepen cooperation in the fields of economy and trade, finance, food security, energy security and disaster relief.

WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.
