BEIJING, May 24 (Xinhuanet) -- CT scan, a widely used heart-imaging test, is likely to result in the over treatment for patients with heart disease, according to a study published online by the Archives of Internal Medicine on Monday.CT, which produces a detailed image of the heart that reveals cholesterol buildups in the coronary arteries, is widely used in the hospital around the world."Testing might lead to more harm than good," said McEvoy, a doctor at Seoul National University Bundang Hospital in S. Korea.His team led the study, in which 2,000 healthy adults were divided into two groups. One thousand adults had CT scans and another half had standard tests, including routine checks of their blood pressure and cholesterol levels.After 18 months, the 215 people who had worrisome CT scans were advised to have additional tests and medical treatment, and some even advised to have surgery. But less than 10 percent in the group of standard test were reported to need medications.Therefore, physicians cannot easily ignore the diagnoses made by the new imaging techniques, McEvoy said, "We are left with the dilemma of what to do with the results,"According to McEvoy, doctors should focus on patients' lifestyle and traditional risk factors such as smoking and obesity.

BEIJING, Feb. 24 (Xinhua) -- Graft remains one of the Chinese people's top concerns, as indicated by online polls from two mainstream media in China prior to the country's annual parliamentary and political advisory sessions.As of 9 p.m. on Thursday, over 54,000 Internet users voiced their concerns over "the fight against corruption and efforts to build a clean government" in an online survey launched by the Xinhua News Agency.Corruption came in at fourth place behind "curbing housing prices," "income distribution" and "control of commodity prices."The poll was launched by Xinhua and was meant to solicit public opinion ahead of the annual sessions of the National People's Congress (NPC) and the National Committee of the Chinese People's Political Consultative Conference (CPPCC).In a survey posted on People.com.cn, a website subsidiary of the People's Daily newspaper, "anti-graft" was among the most selected topics following "social security" and "judicial justice."Internet users pinned their hopes on the forthcoming parliamentary and political advisory sessions, which are scheduled to open in early March.They hope that their voices would be heard by the country's lawmakers and political advisors, who would represent them in the two sessions and would take all possible measures to tackle a number of social issues including the fight against corruption."I hope that the Central Committee of the Communist Party of China (CPC) combats graft comprehensively and severely to ensure a Party with a clean work style, a society with justice and assures the Chinese people that they would not be wronged," said an Internet user from Jiangxi province in a forum entitled "voicing my wishes to Premier Wen Jiabao at the 2011 two sessions " on xinhuanet.com.Internet users believe that the spread of corruption in some places had hindered China's economic development, undermined social stability and harmed the relationship between the people and officials.The fight against corruption, therefore, is a significant factor in determining whether or not China can reach its goals outlined in its Twelfth Five-year Program (2011-2015) on National Economic and Social Development, an Internet user wrote."Corruption has affected Chinese people's life through its spread into many social sectors. As the two sessions represent an open platform to reflect the people's will, citizens hope to push forward the cause of anti-corruption through legislation, thus addressing their common concerns." said Ren Jianmin, director of the Anti-corruption and Governance Research Center of Tsinghua University.The CPC has never relaxed its efforts to fight against corruption, experts say.Last year saw four ministerial-level Chinese officials placed under a graft probe or removed from their posts. Among these officials were Zhang Jiameng, former vice chairman of the Zhejiang Provincial People's Congress Standing Committee in southeast China, and Zhang Jingli, former deputy director of the State Food and Drug Administration.Another 11 ministerial-level officials were sentenced to life imprisonment or other severe punishments in 2010.On February 12 this year, Liu Zhijun, the Chinese Minister of Railways, was removed from his post as the Party chief of the ministry over an alleged "severe violation of discipline," becoming the latest senior official to be investigated in the country's battle against corruption.Experts believe that the downfall of high-ranking officials over corruption charges have clearly shown the determination of the CPC to enforce the Party's discipline, combat corruption and promote a clean work style.On January 10 this year, Chinese president Hu Jintao called for efforts to tackle prominent problems that have seriously harmed people's interests and sparked most public complaints during a plenary session of the CPC Central Commission for Discipline Inspection (CCDI), the Party's anti-graft body.He also pledged to combat graft and punish corrupt officials severely to win the trust of the people.Further, the CPC's drive to erase corruption yielded significant results last year.A total of 5,098 leaders at the county level or above have been punished and 804 officials were referred for prosecution last year, said Gan Yisheng, the deputy secretary of the CCDI, on January 6 this year.Despite the achievements accomplished by the CPC in its fight against corruption, Ren Jianmin believes that the anti-graft situation in China is grave and the task remain arduous.Problems concerning land acquisition and compensation, housing, food and drug safety, environmental protection, work place safety and equal access to education have been reported by the public.To handle these issues, CCDI secretary He Guoqiang urged officials on January 12 to "put people first" and "exercise the state's power for the people" when addressing problems that the public complains about.He, also a member of the Standing Committee of the CPC Central Committee Political Bureau, said that efforts should be enhanced to fight graft in fields that are most vulnerable to corruption and unhealthy practices."The two sessions have a special role to play in China's fight against corruption," said Li Chengyan, a professor at the School of Government in Peking University."Every year, the Party and the government will take effective measures after the two sessions, as a response to social concerns. The people and the media's focus on anti-graft work will push the government to solve relevant problems," he said.According to experts, however, what's more important is to put in place a sound system concerning anti-corruption, promote reform and ensure the implementation of existing measures.

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.

CAPE TOWN, April 30 (Xinhua) -- The World Economic Forum on Africa, scheduled on May 2-4 in Cape Town, South Africa, will see participants exchange views on how the continent can turn to the next chapter of development.The meeting, expected to gather a record 900 participants from over 60 countries, will be held under the theme "From Vision to Action, Africa's Next Chapter," organizers said."We chose this theme because we feel it is very relevant for the events that are taking place on this continent, and the opportunity for growth and investment that the international and African communities are seeing," said Katherine Tweedie, head of Africa for the World Economic Forum.Seven of the fastest growing economies in the world in the next five years will be in sub-Saharan Africa, Tweedie noted, saying that a lot of discussion will be devoted to explore drivers behind this growth.Africa's economic growth in recent years have impressed the world. Though being the most underdeveloped continent, Africa have been more resilient than expected during the global economic crisis.The International Monetary Fund (IMF) have predicted that the continent's growth in 2011 will reach 5.3 percent.Under one of the three thematic pillars, "Shaping Africa's Role in the New Reality," the meeting will explore how Africa can take on a leadership role in the new reality and guard against newly emerging global and regional risks. Participants will look at how Africa can strengthen its representation and negotiation capacity on global platforms such as COP 17 and the G20.Meanwhile, the meeting will look into Africa's industrial diversification, which is widely considered as an effective way to increase competitiveness. Discussions under the thematic pillar of "Fostering Africa's News Champions of Growth" will focus on what innovative and entrepreneurial lessons drive Africa's fastest- growing companies, and how can Africa's emerging economies build capacity in science, technology and innovation to move up the value chain.Another topic expected to attract much attention is Africa's inclusive development. In recent years, African decision makers have been looking for ways to attain inclusive development by translating economic growth into better lives for the people.Marcus Courage, managing director of consulting group Africapractice, said ahead of the meeting that Africa must start measuring its economic growth in terms of job creation and progress of value addition of what it produces, rather than the gross domestic product (GDP), if it has to move from vision to action."One of the challenges is that we measure economic success in therms of GDP. That is not fair reflection of action," he told Xinhua.Under the thematic pillar of "Building Partnership for Inclusive Development," participants will debate on how can inclusive growth be put at the heart of a sustainable development agenda for Africa, and how can government of African countries work together with the business sector to distribute more equitably the benefits from the wealth in natural resources, among others.Regarding the highlight of this year's meeting, Tweedie said there will be a strong focus on green growth and the environment agenda, working closely with the South African government, given that South Africa will be hosting the COP 17 meetings in December.The meeting will also have very strong representation from Francophone west Africa for the first time. As a result a good part of the discussions will be focusing on issues taking place in this part of Africa, she added.Although South Africa has hosted the World Economic Forum on Africa for a number of times, this year the host is attracting particular attention.South Africa has joined the BRICS group of countries which also include Brazil, Russia, India and China, becoming the only African member in the grouping. It is also the only country from Africa in G20. In November this year, South African city of Durban will host the 17th Conference of the Parties (COP 17) to the UN Framework Convention on Climate Change.How can the country speak for Africa in the international arena, and what role can it play in facilitating closer cooperation between developing countries is also expected to draw in-depth discussions at the meeting.Meanwhile, participants are also expected to exchange views on issues including Africa's agriculture development, infrastructure construction, China-Africa cooperation, impact of political situation in North African and the Middle East on Africa's economic development, among others.

BEIJING, Jan. 27 (Xinhua) -- A senior Chinese official has called on the country's religious figures to make more contributions to economic and social development by innovating and improving social services.Jia Qinglin, a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, made the remark at a meeting Thursday while offering lunar New Year's greetings to religious circles on behalf of the CPC Central Committee.Jia Qinglin (front, R), chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), and a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, shakes hands with one of the leaders of the religious groups during an informal discussion sponsored by CPPCC in Beijing, capital of China, Jan. 27, 2011, to celebrate the upcoming Spring Festival.Jia said Chinese citizens' freedom in religious belief was fully protected, and the religious circles had provided excellent services for people from around the world during the Shanghai World Expo and Guangzhou Asian Games last year.The official asked the religious circles to pay more attention to helping grassroots religious groups and believers and improving their management.
