BEIJING, Nov. 22 (Xinhuanet) -- Women aged 40 to 49 are not recommended for routine mammography screening for breast cancer, said the new guidelines issued by the Canadian Task Force on Preventive Health Care in media reports Tuesday.The new guidelines are purposed to direct doctors on using mammography, MRI scans, clinical breast exams and breast self-exams. In principle, they pointed out, there is no need for women to take clinical breast exams and breast self examination if there are no signals for breast cancer.Below are the main points from the guidelines which need special attention from women with reasonable doubt on the matter:Women aged 40-49 who have lower risk for cancer should not take routine mammography because of the higher risk for overdiagnosis, overtreatment and false-positives;Women aged 50 to 69 years and aged 70 to 74 years should go for routine screening every two to three years;And there should be no routine clinical breast exams by doctors and no breast self-exams to screen for breast cancer.Dr. Marcello Tonelli, Chair of the Task Force and Associate Professor at the University of Alberta, remarked: "The main effect of screening is to produce patients with breast cancer from among healthy women who would have remained free of breast disease for the rest of their lives had they not undergone screening.""The best method we have to reduce the risk of breast cancer is to stop the screening program," he added, "This could reduce the risk by one-third in the screened age group, as the level of overdiagnosis in countries with organized screening programs is about 50 percent."

BEIJING, Dec. 26 (Xinhua) -- The Standing Committee of the National People's Congress (NPC), China's top legislature, began here Monday to deliberate draft interpretations on two annexes of the Basic Law of the Macao concerning election issues.Li Fei, deputy director of the Commission of Legislative Affairs of the NPC Standing Committee, explained the draft interpretations to lawmakers.The Basic Law of the Macao Special Administrative Region (Macao SAR) was adopted in 1993 and went into effect on Dec. 20, 1999.Annex I to the Basic Law provides a method for selecting the SAR's chief executives while Annex II sets the method for the formation of its legislative assembly.Clause 7 of Annex I of the Basic Law says that if there is a need to amend the method for selecting the Chief Executives for 2009, and the terms subsequent to the year 2009, such amendments must be made with endorsement of a two-thirds majority of all the members of the Legislative Council and the consent of the Chief Executive, and they shall be reported to the Standing Committee of the National People's Congress for approval.Clause 3 of Annex II says that if there is a need to amend the method of forming the Legislative Assembly of the Macao Special Administrative Region in and after 2009, such amendments must be made with the endorsement of a two-thirds majority of all the members of the Assembly and the consent of the Chief Executive, and they shall be reported to the Standing Committee of the National People's Congress for the record.Li said that the phase "if there is a need to amend ..." should mean that they may or may not be amended.The decision-making on whether such necessity exists is reserved to the central authorities, or the NPC standing committee, said Li, adding that the Macao SAR government, rather than members of the Legislative Assembly, individually or jointly, should be the proper entity to propose any such amendments.Li also explained that if no amendment to the methods is adopted, the two Annexes should still apply.The full text of draft has not been made public yet, but the points raised by Li are identical to those in the committee's prior interpretations on Hong Kong SAR's Basic Law in 2004.During the deliberation, members of the committee noted that draft would help to safeguard Macao's long-term prosperity and stability.They also believed that it was "proper and necessary" to adopt the draft during this week's session as Macao's chief executive Fernando Chui Sai On had made the issue of modifying the method a "major work" in his policy address for the fiscal year 2012.Chui's statement recognized that "there is agreement that it is appropriate to properly modify the two methods in order to adapt to society's development and progress" and promised to "submit a proposal on whether to modify and - if so - how to modify the methods."Macao expects the formation of its fifth Legislative Assembly in 2013, and the selection of its fourth Chief Executive in 2014.

BEIJING Jan. 10 (Xinhuanet) -- Scientists have found a plant in Brazil using leaves to capture the tiny worms in the soil, according to Monday's Proceedings of the National Academy of Sciences in the U.S.The plant, named Philcoxia, was found in the tropical grassland of Brazil, where the biodiversity is well conserved.As the scientists searching for the answer of why the plant grows the leaves underground, they found the 1.5 millimeters-wide leaves can trap the worms and produce a digestive enzyme to help its roots to absorb the nutrition.Although it is not the first meat-eating plant to be discovered, the finding has still "broaden up our perception about plants," according to researcher Rafael Silva Oliveira, a plant ecologist at the State University of Campinas in Brazil.It suggests that carnivorous plants "may have evolved independently more times in plants than previously thought," he added
