RIYADH, Jan. 14 (Xinhua) -- China and Saudi Arabia pledged to work together to further expand all-around exchanges and cooperation as Chinese Premier Wen Jiabao Saturday unfolded his official visit to the Middle East kingdom.China and Saudi Arabia have treated each other as equals with respect and their cooperation has been fruitful since the establishment of diplomatic ties 22 years ago, said Wen while meeting Crown Prince Nayef bin Abdulaziz Al Saud.In recent years, despite the fact that international and regional situation became ever complicated and volatile, the two countries have strengthened high-level exchanges and promoted political mutual trust, said Wen, adding that the two have always demonstrated mutual understanding and support on issues involving their core interests and of major concern.Chinese Premier Wen Jiabao (L) holds talks with Saudi Arabia's Crown Prince Nayef bin Abdulaziz Al Saud in Riyadh, Saudi Arabia, Jan. 14, 2012.The premier said the decision to lift bilateral ties to an even higher level has shown the two nations' firm commitment to jointly face challenges and protect common interests as the world situation is undergoing profound changes.China would like to work with the Saudi side in deepening exchanges and cooperation in various aspects so as to benefit the two peoples and promote world peace and development, Wen added.He said the two sides should expand trade of crude oil and natural gas and energy-related cooperation as to deepen their energy partnership.Wen also asked the two countries to promote investment cooperation. The Chinese government encourages well-established Chinese companies to participate in Saudi Arabia's infrastructure construction such as railway, sea ports, electricity and telecommunications, he said.The two nations could also enhance security and law enforcement cooperation and promote people-to-people exchanges in areas like education and sports, as well as between the two nations' youths.Nayef said Saudi Arabia and China enjoy a time-honored history of exchanges, adding that the Saudi people have friendly feelings toward the Chinese people and expect even better bilateral ties.With joint efforts, bilateral ties have moved forward continuously with remarkable achievements in bilateral cooperation, he said, added that the partnership has bright prospects.Nayef said Saudi Arabia is willing to further boost political mutual trust with China, expand bilateral cooperation in economy and trade, energy, infrastructure, culture, press, and security, promote friendship between the two peoples, and lift bilateral ties to a higher level.Wen arrived here on Saturday evening after a short official visit to Nepal on the same day.

WASHINGTON, Oct. 3 (Xinhua) -- Researchers at St. Michael's Hospital in Canada have discovered a new function for an enzyme that may protect against organ injury and death from anemia, according to a study appearing Monday in the U.S. journal of the Proceeding of the National Academy of Sciences.Researchers found that when people have anemia, neuronal nitric oxide synthase (nNOS) -- an enzyme in nerve cells that produces nitric oxide, an important signaling molecule in the body -- increases the body's ability to respond, adapt to low oxygen levels and makes the body more efficient in delivering oxygen to tissues. They also found that levels of nNOS in the brain increased in anemic mice, and that the mice without this enzyme die earlier, and with higher hemoglobin levels."Identifying this mechanism may lead to new therapies and approaches to improving outcomes for anemic patients," said Dr. Greg Hare, a researcher at the Li Ka Shing Knowledge Institute of the hospital and one of the lead investigators of the study.Anemia occurs when blood has a lower than normal number of red blood cells or hemoglobin -- an iron-rich protein that carries oxygen from the lungs and heart to the rest of the body. Cells need oxygen to survive and to produce energy for all bodily functions. The condition has many different causes including infection (malaria, HIV, parasites), nutritional deficiencies (iron, folate, B12), genetic mutations, pregnancy, trauma and surgical blood loss."This research will help us identify when an anemic patient is at greatest risk for injury and death when undergoing surgery," said Hare. "Research is underway to test these findings in humans."

BEIJING, Nov. 4 (Xinhuanet) -- The amount of trans fat and other nutritional information will be marked on the labels of prepackaged food, according to the country's first national standard for food nutrition. The labeling will take effect on Jan 1, 2013. "It will help standardize the nutrition facts labeling by food producers and facilitate consumers' rights to know and choose, while improving public awareness of food nutrition," said Yang Yuexin, a senior nutritionist with the Chinese Center for Disease Control and Prevention (CDC). The new regulation by the Ministry of Health stipulates that food labels have to include the food's nutrition information, including levels of energy, protein, fat, carbohydrate and sodium. Food products without proper labels showing the nutritional information will be banned when the new rule takes effect. The new regulation also stipulates that if any hydrogenated or partially hydrogenated fat is used to produce the food, the level of trans fat will have to be highlighted on the nutrition information label. Trans fat is usually produced during food processing when liquid oils are converted into semi-solid fats that help keep food fresh longer. However, the partially hydrogenated oil contains trans fat that can substantially increase the risk of heart disease. However, Zhang Jian, a researcher with CDC's National Institute for Nutrition and Food Safety, said that compared to Western diets, the Chinese diet contains a far lower level of trans fat and there is no need to over react.

HARBIN, Jan. 5 (Xinhua) -- A launching ceremony for the 2012 Sino-Russia Tourism Year was held in northeast China's Heilongjiang province Thursday.The initiative, along with an accompanying initiative to be launched in Russia in 2013, will boost people-to-people exchanges and consolidate Sino-Russian relations, Russian President Dmitry Medvedev said in a statement on Dec. 31, 2011.The initiative is the third of its kind to take place between China and Russia, following Sino-Russia National Year and the Sino-Russia Year of Language held in 2006 and 2009, respectively.The creation of the 2012 Sino-Russia Tourism Year is a vital decision made by leaders of both countries to boost the China-Russia comprehensive strategic partnership of cooperation, said Shao Qiwei, director of China's National Tourism Administration.The tourism year will serve as a platform to display the abundant tourism resources of the two countries, said Grigory Sarishvili, deputy head of the Russia Federal Tourism Agency.Statistics from Russian tourism authorities showed that the number of Chinese tourists to Russia during the first nine months in 2011 saw a year-on-year increase of 52 percent.

SHIJIAZHUANG, Oct. 16 (Xinhua) -- Chickens began being domesticated in China about 8,000 years ago, far earlier than in the rest of the world,according to a recent study on fossils uncovered in north China's Hebei Province.Archaeologists said they had unearthed 116 fossil specimens from 23 types of animals, including pig, dog, chicken, tortoise, fish, and clam, at the Cishan Site, a Neolithic village relic in the city of Wu'an.Several bone fragments were identified to be from domesticated chickens, said Qiao Dengyun, head of the Handan Municipal Institute of Cultural Relics and Archaeology."The chicken bones found at Cishan are slightly larger than wild jungle fowls, but smaller than that of a modern domesticated chicken," said Qiao.Qiao said the bone fossils date back to 6,000 BC, earlier than the oldest domesticated chicken previously discovered in India that dated back 4,000 years."Most of the bones were from cocks, indicating that ancient residents used the practice of killing cocks for their meat and raising hens for their eggs," said Qiao.The Cishan Site, which dates back 10,000 years, was first discovered in the 1970s. At the site, experts have found remnants of China's oldest cultivated millet as well as walnut shells, a discovery that challenged the popular belief that walnuts had been brought to China from what is now Xinjiang Uygur Autonomous Region and Central Asia.
