LOS ANGELES, March 23 (Xinhua) -- People who are more physically active are less likely to have high blood pressure associated with a high-sodium diet, a new study suggests.The study was conducted by researchers at the Tulane University School of Public Health and Tropical Medicine in New Orleans, HealthDay News reported on Wednesday.Study findings were presented at the on-going American Heart Association's meeting on nutrition, physical activity and cardiovascular disease, held in Atlanta, said the report.To explore a potential association between exercise and the hypertensive role of dietary salt, the researchers focused on roughly 1,900 men and women (average age 38) living in a rural region in northern China. None took blood pressure medication during the study, according to the report.For one week all of the participants consumed 3,000 mg of sodium a day in their diet; for another week, they were placed on a high-sodium diet -- 18,000 mg per day.Nine blood pressure readings were taken each week, and questionnaires were completed to assess routine levels of physical activity, ranging from "very active" to "quite sedentary."When switching from the lower-sodium to a high-sodium diet, those who experienced a 5 percent or greater boost in their systolic blood pressure (the heart contraction measure represented by the top figure of a blood pressure reading) were deemed "high salt-sensitive."Those reporting the most physical activity had a 38 percent lower risk of being highly salt-sensitive than the least active group. This group was the least likely to see a 5 percent or greater rise in their blood pressure in response to a high-salt diet.Compared with the most sedentary group, those in the next-to- highest activity group had a 17 percent lower risk of salt- sensitivity, and those in the next-to-lowest activity group had a 10 percent lower risk.The team concluded that engaging in physical activity has a " significant," independent and progressively healthful impact on the degree to which salt sensitivity relates to blood pressure."For those with low physical activity, their blood pressure will increase more if they increase their sodium intake," study co- author Dr. Jiang He, chair of the department of epidemiology at the school, said in remarks published by HeathDay News."It's a little bit of a surprise," He added. "But this is the first study to look at this particular association between physical activity and salt sensitivity and blood pressure. But after thinking it over it makes sense, because we already know that physical activity will reduce blood pressure."High blood pressure, or hypertension, is a leading cause of stroke. Because of salt's association with high blood pressure, the American Heart Association recommends consuming less than 1, 500 mg of sodium per day.

PYONGYANG, Feb. 14 (Xinhua) -- Kim Yong Nam, president of the Presidium of the Supreme People's Assembly of the Democratic People's Republic of Korea (DPRK), met Chinese Minister of Public Security Meng Jianzhu here on Monday.Kim said it was the consistent stand of the Worker's Party of Korea (WPK) and the government and the firm will of the people to develop the traditional DPRK-China friendship generation after generation.The DPRK is sincerely happy to see the great achievement China has made and wish that the Chinese people make even more progress, Kim said.Meng, also a State Councilor, said the traditional friendship between the two neighboring countries has strengthened through the ages. He expressed his expectations of inheriting the friendship, deepening communications and cooperation in various areas and promoting the China-DPRK friendship.Ri Yong Ho, Presidium of Political Bureau of Central Committee of WPK and chief of the Korean People's Army General Staff, also met Meng on the same day.Ju Sang Song, a member of the Political Bureau of Central Committee of the WPK and Minister of People's Security, met Meng on Sunday. The two achieved consensus on making more efforts to develop cooperation and communications on public security to make active contributions to the traditional China-DPRK friendship. An agreement on cooperation between the the two security ministries was signed after the meeting.Meng arrived at Pyongyang on Sunday at the invitation of Ju Sang Song.

HAIKOU, Jan. 28 (Xinhua) -- China's aviation authorities on Friday started to allow helicopters to fly in low-altitude airspace over the tourist island of Hainan on a trial basis for the first time. The aim is to eventually open a part of the country's tightly-controlled airspace to private aircraft.Four helicopters were manned by eight pilots from Shanghai-based Zhengyang Investment Group, a leading domestic firm in the general aviation industry. They are expected to conduct test flights in the sky, 1,000 meters above the ground in Hainan in the next two months.The flight test will collect data for low-altitude flying and test the ground control system's response to emergencies, said Zou Jianming, chairman of Zhengyang Investment Group.Hainan is the first place in China to conduct test flights of private aircraft in low-altitude airspace, said Jiang Sixian, deputy governor of the province. Domestic and foreign firms are both welcome to invest in Hainan's general aviation sector to develop world-class tourism here.China's low-altitude airspace is controlled by the Air Force and the Civil Aviation Administration of China (CAAC). Every private aircraft flight needs approval, and the procedure can take from one day up to a week.But last November, the State Council and the Central Military Commission said that part of the low-altitude airspace would be opened to promote the country's general aviation sector, including the purchase and use of private planes.General aviation refers to the part of the aviation industry that excludes flights for military, law enforcement and public transport. China has only 900 aircraft, 80 airports and fewer than 10,000 pilots in the general aviation segment.The market for general aviation in China is valued at only 13 billion yuan (1.98 billion U.S. dollars) but is expected to grow by 15 percent annually until 2020, Hainan aviation officials said.

WASHINGTON, May 2 (Xinhua) -- Rice originated in China, a team of U.S. genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing.Their findings, which appear Monday in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin -- India as well as China.Asian rice, Oryza sativa, is one of world's oldest crop species. It is also a very diverse crop, with tens of thousands of varieties known throughout the world. Two major subspecies of rice -- japonica and indica -- represent most of the world's varieties. Sushi rice, for example, is a type of japonica, while most of the long-grain rice in risottos are indica.Because rice is so diverse, its origins have been the subject of scientific debate. One theory -- a single-origin model -- suggests that indica and japonica were domesticated once from the wild rice O. rufipogon.Another -- a multiple-origin model -- proposes that these two major rice types were domesticated separately and in different parts of Asia. The multiple-origin model has gained currency in recent years as biologists have observed significant genetic differences between indica and japonica, and several studies examining the evolutionary relationships among rice varieties supported more than domestication in both India and China.In the PNAS study, the researchers re-assessed the evolutionary history, or phylogeny, of domesticated rice using previously published datasets, some of which have been used to argue that indica and japonica rice have separate origins. Using more modern computer algorithms, however, the researchers concluded these two species have the same origin because they have a closer genetic relationship to each other than to any wild rice species found in either India or China.In addition, the study's authors examined the phylogeny of domesticated rice by re-sequencing 630 gene fragments on selected chromosomes from a diverse set of wild and domesticated rice varieties. Using new modeling techniques, which had previously been used to look at genomic data in human evolution, their results showed that the gene sequence data was more consistent with a single origin of rice.In the study, the investigators also used a "molecular clock" of rice genes to see when rice evolved. Depending on how the researchers calibrated their clock, they pinpointed the origin of rice at possibly 8,200 years ago, while japonica and indica split apart from each other about 3,900 years ago. The study's authors pointed out that these molecular dates were consistent with archaeological studies.Archaeologists have uncovered evidence in the last decade for rice domestication in the Yangtze Valley beginning approximately 8, 000 to 9,000 years ago while domestication of rice in the India's Ganges region was around about 4,000 years ago."As rice was brought in from China to India by traders and migrant farmers, it likely hybridized extensively with local wild rice," explained New York University biologist Michael Purugganan, one of the study's co-authors. "So domesticated rice that we may have once thought originated in India actually has its beginnings in China."

HONG KONG, March 18 (Xinhua) -- After over a year's efforts, scientists from Shanghai and Hong Kong announced on Friday that they have completed the whole genomic sequencing work of Isaria cicada, a rare herb highly valued in traditional Chinese medicine, which will help facilitate its further development in medical and nutrition fields.It is the first time that the whole genomic sequence of Isaria cicada has been released, said the scientists from Shanghai Institute of Bio-Asia Life Science and the Hong Kong University of Science and Technology (HKUST), who participated in the research.The result was announced at the International Biomedical Scientists and Biotechnology Forum 2011 held in the day at the Hong Kong Science Park.According to the result, the genomic size of Isaria cicada, a medicine traditionally used to treat children's diseases, is about one eightieth of human genome, containing about 16,000 genes.The tests that had been done proved that Isaria cicada, with many high-quality genes not recognized or used by human beings yet, has been deeply involved in important life processes like metabolism, providing new ways for further development of Isaria cicad in bio-medical area, said a scientist from HKUST.The genome map will also help accelerate the artificial cultivation of Isaria cicada, enhancing its medicine and nutrition value and making it available in a larger market, according to the scientist.
