KUNMING, Nov. 30 (Xinhua) -- More than 10,000 new HIV infections were reported in southwest China's Yunnan province during the first 10 months of this year, bringing the total number of HIV carriers and AIDS patients in the province to more than 90,000, local AIDS prevention authorities said Wednesday.As of Oct. 31, a total of 93,567 HIV infections had been reported in the province, with the disease claiming 14,340 lives, according to statistics from the Yunnan AIDS Prevention Bureau.The number of HIV infections contracted through sexual contact has been rising and sexual contact is now the main cause of the disease's proliferation, said Xu Heping, director of the bureau.Of the province's infected population, 45.8 percent contracted the disease through sexual contact, while 37.3 percent contracted the disease through intravenous drug abuse, according to the bureau.Sexually transmitted infections accounted for 77.3 percent of new infections during the January-October period, up from 71.3 percent during the same period last year, according to the statistics.Xu said this year's new infections mainly occurred in people between the ages of 20 and 39, accounting for 60.8 percent of the total.Infections among rural residents and unemployed people accounted for 55.3 percent and 18.6 percent, respectively, of this year's total, according to Xu.Lu Lin, director of the Yunnan disease control and prevention center, said migrant workers are particularly vulnerable to the disease due to their nomadic nature and lack of knowledge about the disease.China currently has 346,000 registered HIV carriers and AIDS patients, although the actual number is predicted to hit 780,000 by the end of this year, according to an expert panel consisting of members of China's Ministry of Health (MOH), the World Health Organization and UNAIDS.

BEIJING, Jan. 10 (Xinhua) -- China's energy chief said here Tuesday that the country is under greater pressure to ensure energy supply this year as both demand and international competition for resources grows.Liu Tienan, head of the National Energy Administration (NEA), made the remarks when speaking at a national energy work conference."It is always worrisome to have to sustain supply of energy and resources for a country with 1.3 billion people," Liu said.As China is facing a "grim situation" in energy saving and emission reduction, Liu noted, it is urgent to restructure the country's energy use and control the gross consumption volume this year.To ensure a stable energy supply, China will optimize the layout of energy exploration, start construction of energy-transmission projects and other major energy programs while boosting reserves of oil, natural gas and coal in 2012, Liu said.The NEA plans to add another 200 metric tons to the country's coal-producing capacity this year plus 70 million kw of new installed power-generating capacity.If the ecology is protected and people are relocated, China will start construction of hydropower projects of 20 million kw in 2012, according to the NEA.Once safety is ensured, nuclear power will be developed after the country's new safety plan is approved.As for renewable energy development, the NEA plans to launch wind power projects with a total capacity between 15 million kw and 18 million kw, while developing 3 million kw of solar power over the new five-year period ending 2015.Liu said, in 2012, the country aims to provide electricity to another 600,000 people who currently have no access to it and expand electricity access to 5 million people by 2015.The NEA has budgeted 65 billion yuan (10.3 billion U.S. dollars) for upgrading the grids in rural areas.Over the next four years, China will facilitate the development of non-conventional natural gas, such as shale gas and coalbed methane by increasing the number of natural gas users by 100 million to 250 million.A key indicator measuring the economic vitality, power consumption rose 11.7 percent year-on-year to 4.7 trillion kWh in China in 2011. The growth in 2012 is expected to slow to 8.5 percent amid the country's economic slowdown.

BEIJING, Jan. 7 (Xinhua) -- The two-day National Financial Work Conference concluded Saturday, laying out development plans for the financial sector in the coming five years, according to a statement released after the meeting.Chinese Premier Wen Jiabao was present at the conference and delivered a keynote speech.Such a conference is held every five years. Similar meetings were held in 1997, 2002 and 2007.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

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.
