XICHANG, Sichuan, June 21 (Xinhua) -- China successfully launched a new communication satellite, the Zhongxing-10, from its Xichang Satellite Launch Center in southwest Sichuan Province on early Tuesday.The satellite, carried by a Long March-3B rocket carrier, blasted off from the center at 0:13 a.m., said a statement from the center.According to statistics from the control center, the satellite successfully separated from its carrier rocket and entered Earth's orbit as scheduled, 26 minutes after being launched.The Zhongxing-10 was designed and manufactured by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation.The satellite will provide communication, broadcasting and data transmission services for users in China and the Asia-Pacific region. It will replace the Zhongxing-5B satellite, which was launched in 1998.The launch was the 138th mission for the Long March carrier rocket series.

WASHINGTON, June 6 (Xinhua) -- Women who have higher levels of the appetite-controlling hormone leptin have fewer symptoms of depression, and this apparent inverse relationship is not related to body mass index (BMI), a new study finds. The results were presented Monday at The Endocrine Society's 93rd Annual Meeting in Boston, the United States."Animal data suggest that leptin may reduce anxiety and improve depression. Our study in women suggests that leptin may indeed have antidepressant qualities," said the study's lead author, Elizabeth Lawson, of Massachusetts General Hospital and Harvard Medical School in Boston.Leptin, the product of fat cells, signals satiety, or fullness. It is low in thin women and high in obese women, according to Lawson. She also said there is an increased prevalence of anxiety and depression in certain conditions in which leptin levels are typically low. These include the eating disorder anorexia nervosa, in which there is abnormally low weight and body fat, and functional hypothalamic amenorrhea, in which women have stopped menstruating despite having normal weight."It is unknown whether low leptin levels contribute to the development of mood disorders in these women," Lawson said.She and her co-workers studied the relationship between leptin levels and symptoms of anxiety and depression in 64 women. Fifteen of the women had anorexia nervosa, 12 were normal weight with hypothalamic amenorrhea, 20 were normal weight and in good health, and 17 were overweight or obese but still healthy.All subjects were asked questions to assess symptoms of depression and anxiety, with high scores indicating more symptoms. Besides measuring leptin levels in the blood, the researchers assessed the women's BMI, a measure of weight for height.The relationship between leptin and depression symptoms was independent of BMI. This finding indicates that leptin may mediate symptoms of depression and that this effect is not a function of low weight, Lawson said."Further research administering leptin to humans will be important in understanding whether this hormone has a potential role in the treatment of depression," she said.

BEIJING, June 26 (Xinhua) -- A drama honoring an archivist who had devoted himself to the Chinese People's Liberation Army (PLA)'s archive work was staged Saturday evening in Beijing.The drama, "Sheng Ming Dang An," or "Archives of Life," tells the life story of Liu Yiquan who had worked as a file clerk and later a consultant at the PLA Archives for about 38 years.Liu had collected more than 830,000 pieces of military archives, which was regarded as a special contribution to the army. Li Changchun (L, front), a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, congratulates actors on the successful performance of drama "life archives" in Beijing, capital of China, June 25, 2011.Despite being diagnosed with terminal cancer in 2008, Liu continued to work hard.

BEIJING, Aug. 1 (Xinhua) -- The after-tax CIF (cost, insurance and freight) price of China's jet fuel imports has been set at 7,768 yuan (1,206 U.S. dollars) per metric ton for August, China's economic planner said on Monday.The price adjustment marked the first time for the economic planner to adjust jet fuel prices on a monthly basis after it announced jet fuel pricing reforms in July, according to a notice posted on the National Development and Reform Commission (NDRC)'s website.The NDRC announced on July 7 that it would introduce a market-oriented jet fuel pricing mechanism starting from Aug. 1.Under the new mechanism, the ex-plant price of jet fuel is required to be no higher than the after-tax CIF price of jet fuel imports from Singapore, Asia's largest oil trading and storage center.Taking transportation expenses, trade volumes and international crude oil prices into account, the jet fuel premium is negotiable between jet fuel sellers and buyers and will be reviewed once a year, while jet fuel ex-plant prices will be adjusted on the first day of every month, according to the NDRC.
