WASHINGTON, Jan. 2 (Xinhua) -- A hormone derived from visceral fat called adiponectin may play a role as a risk factor for development of all-cause dementia and Alzheimer's disease (AD) in women, according to a study published on Monday in online issue of the Archives of Neurology.Thomas van Himbergen, from Human Nutrition Research Center on Aging at Tufts University, and colleagues measured levels of glucose, insulin, and glycated albumin, as well as C reactive protein, lipoprotein associated phospholipase A2, and adiponectin in the plasma of patients at the 19th biennial examination (1985 -- 1988) of the Framingham Heart Study.The 840 patients (541 women, median age of 76 years) were followed-up for an average of 13 years and evaluated for signs of the development of AD and all-cause dementia. During that time, 159 patients developed dementia, including 125 cases of AD. After adjustment for other dementia risk factors (age, low plasma docosahexaenoic acid, weight change) only adiponectin in women was associated with an increased risk of all-cause dementia and AD."It is well established that insulin signaling is dysfunctional in the brains of patients with AD, and since adiponectin enhances insulin sensitivity, one would also expect beneficial actions protecting against cognitive decline," the authors write. "Our data, however, indicate that elevated adiponectin level was associated with an increased risk of dementia and AD in women."

BEIJING, Jan. 21 (Xinhua) -- A locomotive producer in central China's Hunan province on Friday rolled out a low-cost magnetically levitated (maglev) train that is more environmental-friendly than conventional ones.The three-carriage train is designed to run at a maximum speed of 100 km per hour and carry 600 passengers, said Xu Zongxiang, general manager of Zhuzhou Electric Locomotive Co. Ltd. of China South Locomotive and Rolling Stock Corporation (CSR). Xu said the new train was much quieter than conventional ones. While a conventional train moves forward by using friction between its wheels and the railway tracks, the maglev train replaces wheels by electromagnets and levitates on the guideway. According to Xu, his company's has minimized the risk of the new maglev train derailing or overturning. "It's ideal for mass transportation, as it is quiet and environmental-friendly. Its manufacturing cost is about 75 percent of a conventional light-rail train," said Xu. The maglev train has a minimum turning radius of 50 meters and can easily run in residential communities or on hilly slopes. "It's an ideal public transport option for Chinese cities and major tourist destinations," said Xu. Railway transport specialist Liu Youmei, also an academician with Chinese Academy of Engineering, said the new train is green, economical and safe. "It can be used for public transport in populous areas and at scenic spots with fragile environments." Liu said China is one of a few countries that have applied maglev technology. Beijing is building a maglev route, the Daitai line (S1), which starts at its IT center in Haidian district, passes through Shijingshan district, and ends in Mentougou district on its western outskirts. The line will be operational next year.The eastern metropolitan of Shanghai runs the world's first commercial maglev system on a 30-km stretch between the downtown business district and Pudong airport. The German-made maglev went into operation on Dec. 31, 2002.

BEIJING, Dec. 2 (Xinhua) -- China cannot use its 3.2 trillion U.S. dollars in foreign exchange reserves to rescue other countries, a senior diplomat said on Friday."The argument that China should rescue Europe does not stand, as reserves are not managed that way," Vice Foreign Minister Fu Ying said at the Lanting forum, a gathering of Chinese officials, scholars and social groups held by the Ministry of Foreign Affairs to discuss international issues and foreign policy."China is not absent from international efforts to rescue Europe; it has been a positive and healthy participant," Fu said.Since the outbreak of the European financial crisis, China has dispatched more than 30 procurement delegations to Europe, helping to boost imports from the continent, Fu said.Fu added that there are many misunderstandings about the use of China's foreign reserves. "Foreign reserves are not domestic income or money that can be disposed of by the premier or finance minister," she said."Foreign reserves are akin to savings, and their liquidity should be ensured," Fu said."Foreign reserves are not revenue and cannot be relocated randomly. Under this circumstance, China should take the prospect of yields into consideration if it invests its foreign reserves," said Tian Dewen, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.However, the outlook for the economic situation in the eurozone is currently uncertain, Tian said.Fu said China learned a lesson about the importance of foreign reserves during the Asian financial crisis of the late 1990s. ' "Reserves cannot be used domestically to alleviate poverty or taken abroad for development support," she said.She said that the way in which foreign reserves are managed should be in line with the principles of "safety, liquidity and proper profitability.""China's purchases of European bonds, International Monetary Fund bonds and U.S. bonds are also based on those principles," Fu said.Fu also said that China has no intention to gain profit by leveraging financial instruments."China will make efforts to overcome the crisis with Europe and the international community in the future," Fu said."As for the current turbulence in European markets, an authoritative voice is necessary in restoring market confidence. However, voices are diversified in Europe due to its political framework," said Chen Xin, an analyst at the Institute of European Studies at the Chinese Academy of Social Sciences.Fu also reviewed achievements made in trade and investment cooperation between the two sides."It is normal for Europe to strengthen its economic cooperation with China in the process of conquering its difficulties, although it is not proper to add negative political implications," Fu said.She urged Europe not to politicize China's foreign investments."Successful investment should be reciprocal. We hope our economic activities are not interpreted from a political prospective and are not imbued with political interests. We should follow market economy principles," Fu saidFu also took time to single out media reports about the crisis that she believes have been overtly political."Many European countries have shown their understanding and support for us, but there have also been some negative reports," Fu said."We should treat each other with a moderate and impartial mentality. That will make bilateral relations easier to handle," Fu said.She cited an investment bid by a Chinese company in Iceland that was turned down by the country's government.Zhongkun, a private Chinese real estate company founded in 1995, planned to buy 300 square km of land in Iceland to build a high-end resort with a total investment of 200 million U.S. dollars.However, Iceland's Interior Ministry rejected the bid, citing the size of the area of land involved and the fact that there is no precedent in Iceland for foreign countries to purchase large tracts of land.

BEIJING, Dec. 16 (Xinhua) -- China issued rules for pilot programs of RMB Qualified Foreign Institutional Investors (RQFII) on Friday, formally giving a green light to investment of overseas RMB funds in mainland securities markets.The move is expected to widen the investment channel of overseas RMB funds and add new momentum to the country's bid to make the RMB an international currency.Hong Kong subsidiaries of fund management companies and securities firms can use RMB funds raised in Hong Kong to invest in mainland securities within a permitted quota, according to the rules jointly released by the China Securities Regulatory Commission (CSRC), the People's Bank of China and the State Administration of Foreign Exchange.The total investment quota of RQFII pilot programs is set at around 20 billion yuan (3.15 billion U.S. dollars), according to the rules.To control risks, qualified investors should invest no less than 80 percent of the RMB funds they raised in fixed-income securities, while investment in stocks and equity funds should account for no more than 20 percent.The CSRC will join other related departments to study the possibility of further expanding the trial program after its launch, said a CSRC official who declined to be identified.The launch of the RQFII will open another significant channel for overseas RMB funds to flow back into the country, said the CSRC official.It will also help diversify investment products for overseas RMB funds and facilitate off-shore RMB business, the official said.The RMB is not fully convertible under the capital account but China has stepped up efforts to make the currency more international over the past few years.The government has encouraged the use of the RMB in cross-border trade and investment settlement and approved foreign direct investment in overseas RMB funds obtained overseas.It also allowed Hong Kong to establish an offshore yuan market and has expanded trade settlement agreements and currency swaps to create more channels for the yuan to circulate outside the mainland.
