WASHINGTON, March 25 (Xinhua) -- Researchers at the University of Colorado (CU) and the Harvard University have found that people living at higher altitudes have a lower chance of dying from ischemic heart disease and tend to live longer than others, according to a study published this week in the Journal of Epidemiology and Community Health.They spent four years analyzing death certificates from every county in the United States. They examined cause-of-death, socio- economic factors and other issues in their research.They found that of the top 20 counties with the highest life expectancy, eleven for men and five for women were located in Colorado and Utah. And each county was at a mean elevation of 5, 967 feet above sea level. The men lived between 75.8 and 78.2 years, while women ranged from 80.5 to 82.5 years.Compared to those living near sea-level, the men lived 1.2 to 3. 6 years longer and women 0.5 to 2.5 years more."If living in a lower oxygen environment such as in our Colorado mountains helps reduce the risk of dying from heart disease it could help us develop new clinical treatments for those conditions," said Benjamin Honigman, professor of Emergency Medicine at the CU School of Medicine. "Lower oxygen levels turn on certain genes and we think those genes may change the way heart muscles function. They may also produce new blood vessels that create new highways for blood flow into the heart."Another explanation, he said, could be that increased solar radiation at altitude helps the body better synthesize vitamin D which has also been shown to have beneficial effects on the heart and some kinds of cancer.Despite these numbers, the study showed that when socio- economic factors, solar radiation, smoking and pulmonary disease were taken into account, the net effect of altitude on overall life expectancy was negligible.Still, Honigman said, altitude seems to offer protection against heart disease deaths and may also play a role in cancer development.Colorado, the highest state in the nation, is also the leanest state, the fittest state, has the fewest deaths from heart disease and a lower incidence of colon and lung cancer compared to others.

BEIJING, Jan. 25 (Xinhua) -- China's 11 government departments have jointly released a guideline outlining major measures to lessen noise pollution amid rising noise disputes and complaints, the Ministry of Environmental Protection said Tuesday.The ministry's spokesperson, Tao Detian, said Tuesday the country saw rising complaints about noise pollution, which has caused an increasingly negative impact on the living environment in recent years.The 26-article guideline focuses on addressing noise pollution in fields including industry, construction, traffic and people's daily lives.Further, the regulation bans businesses from using acoustic instruments outdoors to lure customers.Also, heavy noise polluters are banned from entering industrial parks, according to the guideline.Moreover, motor vehicles should strictly observe speed limits, traffic restrictions and use of auto horns around "noise-sensitive buildings" such as hospitals, schools, government organs, scientific research institutions and residential buildings, it said.According to the guideline, government departments would also impose higher fines on noise polluters and collect fees for "discharges of excessive noise," in accordance with law.The newly issued document calls on various government agencies, such as the ministries on environmental protection, science and technology, public security, finance, housing, transportation and railways, to make coordinated efforts to curb pollution.Further, government organs could launch regular inspection campaigns in major cities, it said.According to the guideline, government agencies will set up a system to examine sound-proof qualities of civilian buildings and provide a list of major noise pollution sources by the end of this year.Also, the guideline ordered major cities to establish an automatic noise monitoring system and to equip each city in the country with at least one noise display screen by the end of 2011.

BEIJING, Feb. 5 (Xinhua) -- China's railways transported about 77.34 million passengers during the fifteen days (Jan. 19 to Feb. 2) before the Spring Festival, the Ministry of Railways said.The figure was about 9.5 percent higher than the same period last year and set a new record, according to a report posted on the ministry's website.There were an average of 5.16 million passengers per day, up 448,000 from the same period last year. On Jan. 29, passengers topped 5.78 million, setting a new record for daily transportation before the Spring Festival, the report said.In the fifteen days before the festival, about 4.80 million passengers left Beijing, 8.39 million left Guangzhou and 5.69 million left Shanghai, while year-on-year growth and those leaving Guangzhou rose the most, up 15 percent year on year, said the report.The ministry said challenges still exist as more snow and rain will hit southern China after the Spring Festival, when passengers are returning.China's busy Spring Festival transportation season runs for 40 days and is calculated in two phases: 15 days before the Spring Festival and 25 days after the Spring Festival, the report explained.

Wang said.Hundreds of the nation' s art works are displayed in a dozen halls in the five-storey exhibition area, including oil paintings, ink paintings, wood block prints, shadow puppets, paper cuttings, clay sculptures and embroideries."I changed my mind and got off the bus on my way to a temple fair.
