LOS ANGELES, April 6 (Xinhua) -- Freeze-dried strawberries may play a role in the prevention of esophageal cancer, a new study suggests."Strawberries may be an alternative or work together with other chemopreventive drugs for the prevention of esophageal cancer," said lead researcher Tong Chen, M.D., Ph.D., assistant professor, division of medical oncology, department of internal medicine at the Ohio State University.Study findings were presented at the ongoing 102nd annual meeting of the American Association for Cancer Research (AACR) in Orlando, Florida, according to the American Association for the Advancement of Science (AAAS) on Wednesday."We concluded from this study that six months of eating strawberries is safe and easy to consume. In addition, our preliminary data suggests that strawberries can decrease histological grade of precancerous lesions and reduce cancer- related molecular events," said Chen, who is also a member of the Molecular Carcinogenesis and Chemoprevention Program in the Ohio State University Comprehensive Cancer Center.The study involved a group of participants who consumed 60 grams of freeze-dried strawberries daily for six months and completed a dietary diary chronicling their strawberry consumption.The researchers obtained biopsy specimens before and after strawberry consumption. The results showed that 29 out of 36 participants experienced a decrease in histological grade of the precancerous lesions during the study.Using freeze-dried strawberries was important because by removing the water from the berries, they concentrated the preventive substances by nearly 10-fold, Chen said.Esophageal cancer is the third most common gastrointestinal cancer and the sixth most frequent cause of cancer death in the world, she noted.Chen and her team are studying esophageal squamous cell carcinoma (SCC) which makes up 95 percent of cases of esophageal cancer worldwide. China, where this study took place, has the highest incidence of esophageal SCC, according to the AAAS.In a previous study, Chen and colleagues found that freeze- dried strawberries significantly inhibited tumor development in the esophagus of rats. Based on these results, they embarked on a Phase Ib trial that included participants with esophageal precancerous lesions who were at high risk for esophageal cancer."Our study is important because it shows that strawberries may slow the progression of precancerous lesion in the esophagus," Chen said.But she said they need to test this in randomized placebo- controlled trials in the future.

LOS ANGELES, March 2 (Xinhua) -- Those who take a nap are more likely to have lower levels of blood pressure despite stress, said a new study in the latest issue of International Journal of Behavioral Medicine available on Wednesday.In the study, researchers at Sarah Conklin of Allegheny College in Meadville, Pennsylvania examined 85 healthy university students, who were divided into two groups, with one group taking an hour- long nap during the day, and the other group having no time to sleep. Both groups were given a mental stress test.The study found that participants in both groups experienced increase in blood pressure and pulse rates when they took the stress test, but the average blood pressure of those who slept for at least 45 minutes was significantly lower after the stress test than it was for those who did not sleep.The researchers drew the conclusion that a daytime nap of at least 45 minutes may help stressed-out people lower their blood pressure and protect their heart."Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors," the researchers said in the study."Further research is needed to explore the mechanism by which daytime sleep is linked with cardiovascular health and to evaluate daytime sleep as a recuperative and protective practice, especially for individuals with known cardiovascular disease risk and those with suboptimal sleep quality," they added.Sleep deficiency is common in the United States, posing a long- term health threat. On average, Americans get nearly two hours less sleep a night than they did 50 years ago, according to background information provided by the journal.

WASHINGTON, April 11 (Xinhua) -- Taking a statin before having major elective surgery reduces potentially serious kidney complications, according to a study appearing in an upcoming issue of the Journal of the American Society Nephrology.Each year, more than 230 million major elective surgeries are performed around the world. Unfortunately, many patients who undergo major operations develop kidney injury soon after surgery, often due to decreased blood flow to the kidneys and/or the effects of inflammation.Animal studies suggest that the cholesterol-lowering drugs called statins protect the kidneys from such damage, but whether a similar benefit occurs in humans is uncertain. To investigate, Amber Molnar, University of Western Ontario, and colleagues conducted a population-based retrospective study of all older patients who underwent major elective surgery in the province of Ontario, Canada from 1995 to 2008. Surgeries included cardiac, thoracic, vascular, intra-abdominal, and retroperitoneal procedures.A total of 213,347 patients from 211 hospitals underwent major elective surgery, and 4,020 patients (1.9 percent) developed postoperative kidney injury within two weeks of surgery. A total of 1,173 patients (0.5 percent) required dialysis within two weeks of surgery, and 5,974 patients (2.8 percent) died within a month of surgery.Prior to surgery, 67,941 patients (32 percent) were taking a statin. Patients taking a statin were 20 percent less likely to develop kidney injury, need dialysis, and die compared to patients who were not taking a statin. Also, there was evidence of a dose-effect, with patients on higher potency statins having less kidney injury. In addition, statins were beneficial whether they were started greater than 90 days or less than 30 days prior to surgery."Our study suggests that statin use in older persons results in less kidney injury following major elective surgery and reduces the risk of premature death after surgery," said Molnar, adding that the results warrant further investigation with more rigorous studies, but such trials will be difficult to carry out.

BEIJING, March 13 (Xinhua) -- China's top legislator Wu Bangguo on Sunday met and extended regards to the journalists of leading Chinese media covering the annual sessions of the top legislature and advisory body."You have given full coverage on important issues such as the review of the draft 12th Five-Year Plan and the scheduled establishment of the socialist system of laws with Chinese characteristics," Wu said to the journalists.The stories written by the journalists " fully tell how lawmakers and political advisers performed their deputies, and reflect people's wishes and aspiration," said Wu, chairman of the Standing Committee of the 11th National People's Congress (NPC).Wu said that he expected the public media will do a better job in covering issues regarding to the political development path with Chinese characteristics and the people's congress system.The fourth session of the NPC will conclude on Monday morning, and the fourth session of the National Committee of the Chinese People's Political Consultative Conference ended Sunday.

BEIJING, May 14 (Xinhua) -- From 24-hour complaint hotlines to instant additive detectors, local governments in China are striving to battle the illegal use of food additives following a string of food scandals.According to a statement released Saturday by the office of the food safety commission under the State Council, China's Cabinet, governments in Beijing, Shanghai, Zhejiang and Guangdong have incorporated the local food safety situation into the evaluation of officials' work, while ordering strengthened and coordinated food safety supervision at city and county levels.Many provinces and autonomous regions are distributing educational information through local media to promote, among the local population, the awareness of food safety and the harm of banned food additives, stressing severe punishment in the hope of intimidating potential violators.Certified food additives are displayed on shelves at a store that sells food additives in Beijing, capital of China, April 22, 2011.Law enforcement departments in Chongqing, Guangdong, Liaoning and Hunan have punished violators involved in a series of food scandals which included "poisonous bean sprouts," "inked vermicelli" and "dyed peppers," according to the statement.The document did not provide details on these cases.Meanwhile, governments are figuring out new measures to stem food violations.For instance, the provincial government of northeastern Jilin has set up round-the-clock hotlines for food safety complaints and recruited 1,300 voluntary food safety supervisors who go deep into communities for clues on potential food scandals.Supervisors in southern Guangxi Zhuang Autonomous Region were equipped with additive detecting devices, which are reportedly able to check 27 kinds of illegal food additives "quickly and correctly," including melamine and clenbuterol, a kind of fat-burning drug used by violators to feed pigs to prevent them from accumulating fat.The municipal government of Beijing stipulates that companies found to have committed food violations in the past would be limited in investing in the municipality, while principals responsible for the wrongdoings will be banned from food manufacturing and distribution businesses.Beijing also requires restaurants to inform customers of all food additives contained in their self-made beverages and food sauces by posting the lists in menus or other public places. The lists should also be reported to supervisory departments.According to the statement, the Ministry of Agriculture has sent five teams to various regions, including Hebei, Jilin and Heilongjiang to inspect local food safety conditions.Vice Premier Li Keqiang warned last month of the great harm caused by illegal additives in food during a high-profile national meeting, promising a "firm attitude, iron-handed measures and more efforts" in dealing with the problem."Once such a case surfaces, it has an extensive social impact and easily causes a ripple effect, so we must attach great importance to it," Li said, adding that severe penalties must be imposed on violators to "let the violators pay dearly" and send a message to others.A high-profile, nationwide fight against the illegal use of additives in food was then launched to intensify supervision, upgrade safety standards and greatly increase penalties for violators.The moves came following a series of scandals including steamed buns dyed with unidentified chemicals, as well as the use of illegal cooking oil, known as "gutter oil."In one of the latest cases, police detained 96 people for producing, selling or using meat additives and confiscated over 400 kg of clenbuterol, widely known in the country as "lean meat powder," in central Henan Province.The action followed a scandal revealed in March when the country's largest meat processor, Shuanghui Group, was forced to issue a public apology for its clenbuterol-tainted pork products.
