BEIJING, April 12 (Xinhuanet) -- Doctors may choose riskier treatment with fewer severe side effects for themselves than they'd recommend for their patients, according to a study in the Archives of Internal Medicine Tuesday. In the study, two sets of questions were sent to primary care physicians around the United States. One involved choosing between two types of colon cancer surgery and the other situation involved choosing no treatment for the flu, or choosing a made-up treatment less deadly than the disease but which could cause permanent paralysis. Of 242 physicians who answered the colon cancer questionnaire, 38 percent went with the treatment that carried a higher risk of death but fewer side effects for themselves. By contrast, only a quarter said they would recommend that treatment to their patients.In the flu scenario, 63 percent chose the deadlier option of no treatment for themselves, versus 49 percent recommending it for patients.The findings are important because patients faced with difficult medical decisions often ask their doctors, "What would you do?" The answer reflects the doctors' values -- not necessarily those of the patients.Doctors should know what their patients value most before giving advice, and patients should ask doctors the reasons behind their answers, said study author Dr. Peter Ubel, an internist and behavioral scientist at Duke University.

BEIJING, Jan. 24 (Xinhua) -- China's top economic planner said Monday that price supervision and control measures have achieved steady progress with 2010's Consumer Price Index, slightly exceeding the target ceiling by 0.3 percentage points to hit 3.3 percent.To rein in soaring commodities prices, joint efforts have been made to manage inflation expectations, promote production, ensure supplies and strengthen price supervision in 2010, said the National Development and Reform Commission (NDRC) in an online statement.Prices of necessities accelerating during the second half of 2010 have been contained with vegetable prices down 9.4 percent in December from the previous month last year, it said.Further, prices of edible vegetable, pork, egg, sugar,liquefied petroleum gas and clothing also decreased significantly in December month on month, the statement said.To cope with rising prices beginning in July 2010, especially prices of basic supplies, the central government promptly introduced joint inter-ministerial meetings to discuss price controls among 17 ministries and ordered local governments to establish the same mechanism, it noted.Local governments have worked on improving agricultural facilities, especially in south China's Hainan province, to increase vegetables supplies for northern cities over the past year, the statement said.The statement forecasts that vegetable planting areas in 2010's autumn and winter will increase 530,000 hectares year on year, sending output to 337 million tonnes.To ensure production and supply, departments have worked to reduce fertilizer exports and promote links between production areas and purchasing areas, it added.Further, relevant authorities also took measures to stabilize prices of electricity and coal, and to ensure smooth transportation of agricultural produce.Authorities also granted temporary subsidies and raised basic wages and minimum living subsidies for urban and rural residents to guarantee people's daily life.

BRASILIA, April 26 (Xinhua) -- A survey conducted by Brazil's Ministry of Health showed Tuesday that half of Brazilians aged over 55 have hypertension.According to the research, which has been carried out annually since 2006, the proportion of Brazilians diagnosed with hypertension increased over the past five years, from 21.6 percent in 2006 to 23.3 percent in 2010.Besides, the diagnosis of hypertension is higher among women (25.5 percent) than men (20.7 percent). But in both sexes, the older people are, the more common the disease becomes, the ministry reported.The ministry also said that, to address the problem, the Brazilian government distributes free medicines to control blood pressure, since 80 percent of Brazilians who suffer from hypertension depend on the public health system.The Ministry of Health signed on April 7 an agreement with the food industry, aiming to reduce salt in processed food.If hypertension is left untreated, some complications including clogged arteries, stroke and myocardial infarction will bring patients more troubles.

BEIJING, May 23 (Xinhuanet) -- A new study suggests that crossing your arms could reduce the intensity of pain, according to media reports.The study was conducted by researchers from University College London (UCL), who reported their finding in the journel Pain.They said that crossing the arms could confuse the brain and conflicting information between the brain's two maps - one for the person's body and the other for external space - leading to a lower sensation of pain.A laser was used to generate a four millisecond pin prick on the hands of eight volunteers, who experienced this twice with their arms at their sides and arms crossed.Then the participants were asked to rate the intensity of pain in two situations and an EEG (electroencephalography) was used to measure their electrical brain responses.The results showed that both the perception of pain and EEG activity was reduced when the arms were crossed."Perhaps when we get hurt, we should not only 'rub it better' but also cross our arms," said Giandomenico Iannetti of UCL's department of physiology, pharmacology and neuroscience.
