BEIJING, Aug. 11 (Xinhuanet) -- Next year will bring a doubling in the size of the words that appear on cigarette packages to warn consumers of the dangers of smoking. Starting in April 2012, cigarettes produced and sold in China will bear a new warning label containing letters that will be no less than 4 millimeters in height. That will be twice the size of the current minimum, which stipulates that the letters be at least 2 mm from bottom to top, according to a notice written by the China National Tobacco Corp and published on the State Tobacco Monopoly Administration's website. Despite the intentions, many tobacco-control experts said the step is "minor" and that it fails to deal with the chief issue. "There is no use in making the font size even 100 times bigger if the warning is pointless," said Wu Yiqun, deputy director of the ThinkTank Research Center for Health Development, a Beijing-based non-governmental organization that advocates for the adoption of stronger smoking-control measures. Both Wu and Yang Gonghuan, director of the tobacco control office of the Chinese Center for Disease Control and Prevention, said the warning that now appears on cigarette packs is too weak. It says: "Smoking is harmful to your health. Quitting early is good for your health." "The package should inform consumers of the dangers of smoking in accordance with requirements adopted by the World Health Organization Framework Convention on Tobacco Control. (It should say that) smoking causes lung cancer, coronary disease and makes people grow old," Yang said. China decided in 2005 to ratify the convention, which also requires that tobacco warnings cover a third of the surface of cigarette packs. "Even if the size of the words is doubled, it still doesn't meet those standards," Yang said. "The Chinese practice is to draw a line to demarcate a third of a cigarette package, where the warning should be, but the words put on it are still very small." Experts said graphic health warnings could be printed on cigarette packs and used as a "scientific, direct and shocking" deterrent to smoking.Throughout the world, more than 1 billion people in 19 countries live under laws that require the packaging of various types of tobacco products to bear large, graphic health warnings. They often show pictures of black lungs and festering mouth sores, according to the World Health Organization. China, though, is excluded from those rules. Both Wu and Yang said the fundamental barrier to better control of tobacco use in the country is the fact that the China National Tobacco Corp, the country's largest cigarette-maker, is a subsidiary of the State Tobacco Monopoly Administration, China's tobacco regulatory body.

LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.

BEIJING, June 13 (Xinhua) -- The Chinese government on Monday launched a week-long campaign throughout the country which aims to make the public think more about food safety.Vice Premier Li Keqiang relayed to the campaign's organizer that it is essential to publicize knowledge and regulations on food safety among the public.Li, member of the Politburo Standing Committee of the Communist Party of China (CPC) Central Committee, said that special operations and severe punishment should be adopted to decrease the likelihood of food safety scandals.As part of the campaign, a food safety inspection team under the National People's Congress (NPC) Standing Committee held a conclusive meeting in Beijing to review its two-month supervisory tour to Jiangsu, Hubei, Sichuan and other four provinces and regions in April and May.A statement released by the inspection team on Monday said it will issue a report on food safety problems to the NPC Standing Committee.China's food safety has become a major public concern since a nationwide tainted milk powder scandal was exposed in August 2008.China's top legislature passed the Food Safety Law in 2009 which was soon followed by a nationwide food safety inspection.In the latest food safety scandal, drinks and food sold on the mainland but produced in Taiwan have been found to contain the toxic plasticizer DEHP.China's Ministries of Public Security, Agriculture, Health, as well as the General Administration for Quality Supervision, State Food and Drug Administration are also involved in the campaign.

CANBERRA, Aug. 17 (Xinhua) -- Australian scientist on Wednesday said his international research team has discovered the trick on how butterfly learn to change its wing pattern to avoid being eaten by birds.The Amazonian butterfly, Heliconius numata, has learnt to carry out a single genetic switch to alter its wing pattern so it appears to be another bad-tasting butterfly that birds will avoid.Dr. Siu Fai (Ronald) Lee from the Department of Genetics and Bio21 Institute at Australia's University of Melbourne was part of the international research team, which was led by scientists at Centre National de la Recherche Scientifique (CNRS) and the University of Exeter in United Kingdom.Dr. Lee said the historical mystery had puzzled researchers for decades."Charles Darwin was puzzled by how butterflies evolved such similar patterns of warning coloration," Dr. Siu Fai (Ronald) Lee from the Department of Genetics and Bio21 Institute at the University of Melbourne told Western Australia Today."We have now solved this mystery, identifying the region of chromosome responsible for changing wing pattern."He said the research team identified a genetic switch known as a supergene, which allowed the butterfly to morph into several different forms, allowing one species to mimic another."It is amazing that by changing just one small region of the chromosomes, the butterfly is able to fool its predators by mimicking a range of different butterflies that taste bad," he said."The butterflies rearrange this supergene DNA like a small pack of cards, and the result is new wing patterns. It means that butterflies look completely different but have the same DNA."There are other butterflies doing similar tricks, but this is the most elegant one."I was just fascinated by how elegant they were."He said the discovery proves that small chromosomal changes can preserve successful gene combinations, and thus help a species to adapt.The findings of the study are published on August 14 in the international journal Nature.

TEHRAN, June 15 (Xinhua) -- Iran puts the Rasad (surveillance) satellite in the orbit on Wednesday, the state IRIB TV website reported.The Rasad satellite will render images to the country, said the report.All the procedure of designing, construction, testing and preparations to launch the satellite have been conducted domestically by Iranian experts, according to IRIB.The Rasad, weighs 15.3 kilograms and has been designed to be launched at 260 kilometers above the earth, said IRIB, adding that it will circle the earth 15 times in 24 hours.
