BEIJING, March 7 (Xinhua) -- The Chinese currency Renminbi (RMB), or the yuan, on Monday strengthened to an all-time high of 6.5651 per U.S. dollar, according to the China Foreign Exchange Trading System.Monday's central parity rate of the RMB against U.S. dollar was 20 basis points lower than the previous record of 6.5671 set on last Friday.The yuan has appreciated 3.84 percent since June 19 last year when the People's Bank of China, the central bank, announced it would further reform the exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market for each business day.

LOS ANGELES, March 2 (Xinhua) -- Those who take a nap are more likely to have lower levels of blood pressure despite stress, said a new study in the latest issue of International Journal of Behavioral Medicine available on Wednesday.In the study, researchers at Sarah Conklin of Allegheny College in Meadville, Pennsylvania examined 85 healthy university students, who were divided into two groups, with one group taking an hour- long nap during the day, and the other group having no time to sleep. Both groups were given a mental stress test.The study found that participants in both groups experienced increase in blood pressure and pulse rates when they took the stress test, but the average blood pressure of those who slept for at least 45 minutes was significantly lower after the stress test than it was for those who did not sleep.The researchers drew the conclusion that a daytime nap of at least 45 minutes may help stressed-out people lower their blood pressure and protect their heart."Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors," the researchers said in the study."Further research is needed to explore the mechanism by which daytime sleep is linked with cardiovascular health and to evaluate daytime sleep as a recuperative and protective practice, especially for individuals with known cardiovascular disease risk and those with suboptimal sleep quality," they added.Sleep deficiency is common in the United States, posing a long- term health threat. On average, Americans get nearly two hours less sleep a night than they did 50 years ago, according to background information provided by the journal.

NANJING, April 23 (Xinhua) -- At a time when almost every commodity in China is getting more expensive, the dwindling cost of medicine is a rarity.Zhang Jinkui, a hypertension patient, buys medicines from the community health center of his neighborhood in Changzhou, a city in east China's coastal Jiangsu Province.His prescription list includes Aspirin Enteric-coated tablets, down to 1.4 yuan from 4.7 yuan (0.7 U.S. dollars) per unit, and Fosinopril Sodium Tablets, down to 41.39 yuan from 51.6 yuan per unit.Both drugs are found on the essential drug list unveiled in 2009. The list names the 307 most common western and traditional Chinese medicines, which are heavily subsidized so hospitals can sell them at cost price.A consumer buys medicines with the help of a retailer at a pharmacy in Lianyungang, east China's Jiangsu Province, March 28, 2011.All essential medicines are listed by their generic names, and drug producers compete to supply essential medicines through public procurement.Due to a long history of low government funding for state-run hospitals, which often covers only 10 percent of the hospitals' operating costs, doctors have generated income for hospitals by aggressively prescribing expensive, and sometimes unnecessary, medicines and treatments.The essential medicine system and the reform of publicly funded hospitals, two pillars of China's health reform, are designed to address high medical costs and low accessibility of medical services.In April 2009, China kicked off health reforms aimed at correcting these long-standing problems facing China's health system and easing public grievances.Two years later, the essential medicine system has reduced drug prices, but still fails to please hospitals, patients and drug producers.The system requires government-funded grassroots health clinics, including urban community health centers and rural clinics, to prescribe only essential medicines and to sell these medicines at cost price, rather than with the previous 15 percent mark-up.Such policies have brought hard times to grassroots health clinics, especially in cash-strapped areas.Song Wenzhi, a public health professor at Peking University, said "Grassroots health clinics, without the expertise to perform operations and other treatments, rely heavily on selling drug," adding that these hospitals have found themselves scraping by due to the zero percent mark-up policy.Wang Zhiying, Vice Director of the People's Hospital of Anxiang County in the city of Changde, Hunan Province, said four grassroots hospitals in Changde tested the essential medicine system as pilot projects, but the zero percent mark-up policy took away 60 to 70 percent of the hospitals' revenue.Wang was quoted by "Health News," a newspaper run by China's Ministry of Health, as saying that, due to financial difficulties, the county government had not yet channeled the 8 million yuan (1.2 million U.S.dollars) in support funds into the hospitals' accounts, resulting in the resignations of many doctors.The essential medicine system covers 60 percent of government-funded grassroots hospitals and drug prices have fallen by an average of 30 percent, said Sun Zhigang, Director of the Health Reform Office under the State Council, or China's Cabinet.According to the health reform plan for 2011, the essential medicine system will cover all government-sponsored health institutions at the grassroots level by the end of the year and drugs will be sold there at a zero percent mark-up.Song Wenzhi said the key will be the commitment of local governments to health reform and their financial input. This way, essential medicines can benefit the public without bankrupting grassroots health institutions."That would be a great sum of money." said Song, citing his own studies. "There are roughly 5,000 government-funded hospitals in China. One third of them make profits, one third barely break even, and still one third rely heavily on government subsidies."To maintain the poorest hospitals, central and local level governments would need to invest 15 billion yuan (2.3 billion U.S. dollars) each year, according to Song's estimate.

JINAN, Feb. 3 (Xinhua) -- Chinese Premier Wen Jiabao on Wednesday and Thursday visited drought-hit villages and ordered all-out efforts to combat the dry spell while celebrating the Chinese New Year with local people.When visiting Jiaxiang County and Qufu City in east China's Shandong Province, Wen inspected cornfields and reservoirs to assess the drought's impact.The drought, which began in October, has hit the southwest parts of Shandong hardest."It's hard to know when it will rain. We must prepare for the worst and do our best to combat the drought to ensure a good harvest," Wen said while visiting a reservoir in Qufu.Wen made the remarks Wednesday afternoon after learning the reservoir was holding a volume of water 8 million cubic meters less than normal.He told officials accompanying him any drought-caused reduction in grain output may undermine the government's top priority for 2011: the stabilization of prices.Officials at all levels must work to combat the drought, Wen added.China's central authorities last week announced an ambitious water conservancy project development plan, to raise China's ability to control flooding and drought.Under the plan, the average annual government spending on such projects will double the 2010 level."The drought affects agricultural output, which is related to the nation's food security and the income of rural people. I worry about it," Wen told a local farmer Wednesday morning.In the evening, Wen joined Liu Xianglun, 77, and his family at their house to make dumplings to eat to welcome the Chinese New Year.Before visiting Shandong, Wen visited farmers and workers in Dabieshan Mountain area, an old revolutionary base in east China's Anhui Province.The Spring Festival, China's Lunar New Year, falls on Thursday.

MOSCOW, April 22 (Xinhua) -- The Russian Space Forces has re-established contact with a military satellite, Geo-IK-2, which went missing in February, local media reported Friday.According to a spokesman from the Defense Ministry, Interfax news agency said the Space Forces had already received telemetric information from the satellite and collection and analysis of the data were currently underway.After studying the information, the Defense Ministry would make a decision regarding the further use of the satellite, the spokesman said.A Rokot light-class carrier rocket carrying with the Geo-IK-2 satellite blasted off Feb. 1 from Russia's Plesetsk launching site, but placed the satellite in an incorrect orbit. After the launch, the Defense Ministry announced it had lost contact with the Geo-IK-2 and later abandoned the satellite.The Russian Space Forces then grounded launches of all Rokot light-class carrier rockets until the completion of an investigation into the failed launch.
