WASHINGTON, April 3 (Xinhua) -- Scientists have confirmed that metabolic syndrome, a constellation of conditions that increases the risk of heart disease and diabetes, may also increase the risk of the two most common types of liver cancer, according to data presented at the American Association for Cancer Research's 102nd Annual Meeting 2011, held in Orlando, Florida on April 2-6.Katherine McGlynn, a senior investigator at the National Cancer Institute, said approximately one-third of the U.S. population has metabolic syndrome, which is defined as the co-occurrence of at least three of the following five conditions: raised blood pressure, elevated waist circumference, low HDL or "good" cholesterol, raised triglyceride levels and raised fasting plasma glucose levels.According to McGlynn, persons with these conditions may be at increased risk of developing hepatocellular carcinoma and intrahepatic cholangiocarcinoma.For the current study, researchers identified 3,649 cases of hepatocellular carcinoma and 743 cases of intrahepatic cholangiocarcinoma. They compared the medical history of these patients with the medical histories of 195,953 cancer-free adults.Statistical analyses showed that the persons with liver cancer were significantly more likely than cancer-free persons to have a prior history of metabolic syndrome: 37.1 percent of patients with hepatocellular carcinoma had pre-existing metabolic syndrome, as did 29.7 percent of patients with intrahepatic carcinoma; only 17.1 percent of the cancer-free adults had metabolic syndrome.Liver cancer incidence has been rising since the 1980s in the United States. The factors related to the increase are not well understood. "A lot of attention has focused on viral risk factors, but a significant part of the increase may be due to metabolic syndrome, as well as to diabetes and obesity," said McGlynn."The prognosis for liver cancer is only marginally better than the prognosis for pancreatic cancer, with a five-year survival of approximately 10 percent," she said. "Prognosis is more favorable, however, when liver cancers are diagnosed at early stages when they are small and localized to the liver."

CARACAS, March 30 (Xinhua) -- The number of confirmed cases of the A/H1N1 influenza in Venezuela has risen to 482 this year, Health Minister Eugenia Sader said on Wednesday.According to the latest report, the state of Merida in southeastern Venezuela has 189 A/H1N1 influenza cases, the biggest number ever reported, which was followed by the Capital District of Caracas with 112 cases. The other 181 cases were confirmed in 17 of 24 Venezuelan states.The first case for this year was reported in Merida earlier this month.Sader said that the Venezuelan government was trying to prevent the spread of the disease. Some 3 million people have been vaccinated against the virus.Three patients infected with the A/H1N1 influenza virus have died in the country this year, according to Sader.The A/H1N1 influenza can cause deadly pneumonia if it is not treated early.

BEIJING, Feb. 12 (Xinhua) -- China's recent revocation of a national scientific award due to academic fraud has been welcomed by the public, but experts warn the country still has a long way to go to bring an end to such dubious academic practices.On Feb. 1, China's Ministry of Science and Technology, revoked the State Scientific and Technological Progress Award (SSTPA) given to Li Liansheng, former professor of Xi'an Jiaotong University in 2005.An investigation found Li had plagiarized others' works and fabricated data in his winning project, a research on key technologies for designing and manufacturing scroll compressors. Li was investigated after the science ministry received tip-offs from six professors (including four retired) in his university.The ministry subsequently canceled his prize and retrieved the money awarded.Zhao Baojing, a senior official with the National Office for S&T Award, told Xinhua it was the first time China had withdrawn a national scientific honor.The revocation soon sparked pubic discussion over academic integrity. Tan Gang, a citizen in Shenzhen, wrote on his microblog, "Though the revocation came a bit late, it is progress. It's a warning against academic misconduct."Shi Ying, vice director of Shanxi Academy of Social Sciences, said, the move demonstrated China's "zero-tolerance" for academic fraud, and would help clean up the academic field."However, academic fraud is still rampant, which not only damages academic integrity, but also harms the innovative capacity of China in a broader sense," said Shi.Anti-fraud activist Fang Zhouzi, who runs a website on anti-academic fraud from his Beijing home, said "This is by far the harshest stance China has ever taken against academic fraud, which should be viewed as progress." He so noted China still has a long way to go in the fight against academic fraud.Fang said, the science ministry's move does not mean China is really cracking down on academic fraud. The plagiarist might have not been found out if it were not for years of unyielding efforts made by the six professors.The scandal again highlights that academic fraud is alive and well in China. A survey conducted among 30,078 respondents in 2009 by the China Association for Science and Technology (CAST) showed that nearly half of the science-related workers in China's research institutes, universities, medical institutes and hospitals think academic cheating is "common."Fang attributed the prevalence of academic fraud in China to lax punishments and loopholes in the academic evaluation system.Zero tolerance of academic fraudChina's science minister, Wan Gang, said on several occasions "We hold zero tolerance for academic fraud."However, Fang said "zero tolerance" was a slogan rather than the actual case. Many cases of academic fraud, even publicly exposed, were "tolerated" eventually. "Lax punishment makes academic fraud less costly."

BEIJING, May 14 (Xinhua) -- The uranium subsidiary of China Guangdong Nuclear Power Group (CGNPG) has said it is developing two large mines in the mainland.The two mines will be located in south China's Guangdong province and northwest China's Xinjiang Uygur Autonomous Region, according to Saturday's China Daily.The move is likely to add as much as 1,000 tonnes to the country's annual production capacity of the nuclear fuel."The two mines are expected to start operation in 2013, each with an annual production capacity of no more than 500 tonnes," the newspaper quoted Zhou Zhenxing, chairman of CGNPG Uranium Resources Co (CGNPG-URC) as saying.

BEIJING, Feb. 11 (Xinhua) -- China plans to dig 1,350 wells in eight major wheat-growing provinces to help ease the ongoing drought that is threatening the country's grain harvest, said the Ministry of Land and Resources (MLR) on Friday.The ministry will establish an anti-drought and well drilling operation headquarters and three front working teams in north China, Huanghuai area - along the Yellow and Huai rivers - and northwest China, said the MLR at a video conference.Also, China Geological Survey, an institution directly under the MLR, will transfer experienced technicians from its nine affiliated units to form three emergency squads and 12 emergency groups to assist local governments in finding water in those regions, said the MLR.Further, the MLR will send geological survey teams from its nine affiliated units and eight provinces, including Sichuan, Yunnan and Guizhou, to the eight provinces, it said.The survey teams will bring 100 sets of advanced geophysical prospecting instruments and 320 sets of drill machines to dig 1,350 wells to ease the water shortages affecting people and livestock, especially those in mountainous areas, and strengthen local irrigation, it noted.The eight provinces include Shandong, Henan, Hubei, Anhui, Shanxi, Shaanxi, Gansu and Jiangsu, which are China's major wheat-producing regions and have been severely affected by months-long drought.The MLR had previously put in place a series of measures to relieve drought and find water, such as making underground water layout maps and sending experts to drought-hit regions to give technical guidance, said the MLR.As of 3 p.m. Thursday, the drought had affected 101.28 million mu (6.75 million hectares) of crops nationwide and left 2.81 million people and 2.57 million livestock short of drinking water, said the Office of State Flood Control and Drought Relief Headquarters.
