WASHINGTON, April 4 (Xinhua) -- New research from the University of Pennsylvania School of Medicine has revealed an increased incidence of major adverse cardiac events (MACE), such as heart attack, stroke, and cardiovascular death, in patients with severe psoriasis. The study results were reported Monday at the annual American College of Cardiology meeting in New Orleans.Psoriasis is a common inflammatory skin disease, and if severe, has been demonstrated to be a risk factor for cardiovascular disease. However, the degree to which psoriasis is associated with MACE has not been defined.In a cohort study analyzing data from a general practice research database, Lead author Nehal Mehta, director of Inflammatory Risk in Penn's Preventive Cardiology program, and colleagues reviewed the case histories of over 3,600 patients with severe psoriasis and 14,300 controls. They found that patients with severe psoriasis have a 53 percent increased incidence of MACE compared to the general population. They also found that having a diagnosed case of severe psoriasis confers an additional ten-year risk of six percent on MACE.Previous work from Mehta and colleagues found that the risk of death from cardiovascular disease increased by 57 percent in patients with severe psoriasis. In addition, the relative risk of death from cardiovascular disease was even higher in younger patients, who were as young as age 40.The researchers conclude that this new estimate of increased ten-year MACE may warrant more aggressive strategies for treatment of cardiovascular risk factors in patients with psoriasis.

KIGALI, Feb. 8 (Xinhua) -- Li Zhaozhuo, vice chairman of the National Committee of the Chinese People's Political Consultative Conference (CPPCC), will head a high-level delegation to Rwanda this month to boost friendly and cooperative ties between the two countries.According to a statement released by Rwanda's Senate on Tuesday, the three-day visit will begin on Feb. 18 and is to strengthen regular contacts between Rwandan and Chinese parliamentary chambers on a number of issues and review bilateral projects.Chinese Ambassador to Rwanda Shu Zhan has confirmed that the official delegation from China is "planning an outreach visit" to Rwanda.After a meeting with the Chinese envoy to Rwanda on Tuesday, the president of Rwanda's Senate, Vincent Biruta, said his country's legislative chambers would continue to promote friendly ties with the CPPCC and play a "constructive role" in promoting bilateral cooperation.Rwanda have received training assistance from China in the applications of information communication technology (ICT) in parliaments.The Central African nation has a long-standing bilateral relationship with China in a number of socio-economic areas such as infrastructure, energy, education, health, agriculture and communications.

WASHINGTON, April 20 (Xinhua) -- Those childhood music lessons could pay off decades later -- even for those who no longer play an instrument -- by keeping the mind sharper as people age, according to a preliminary study published by the American Psychological Association (APA).The study recruited 70 healthy adults age 60 to 83 who were divided into groups based on their levels of musical experience. The musicians performed better on several cognitive tests than individuals who had never studied an instrument or learned how to read music, according to the research findings published Wednesday online in the APA journal Neuropsychology."Musical activity throughout life may serve as a challenging cognitive exercise, making your brain fitter and more capable of accommodating the challenges of aging," said lead researcher Brenda Hanna-Pladdy, a clinical neuropsychologist at the University of Kansas Medical Center. "Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older."The three groups of study participants included individuals with no musical training; with one to nine years of musical study; or with at least 10 years of musical training. All of the participants had similar levels of education and fitness and didn' t show any evidence of Alzheimer's disease.All of the musicians were amateurs who began playing an instrument at about 10 years of age. More than half played the piano while approximately a quarter had studied woodwind instruments such as the flute or clarinet. Smaller numbers performed with stringed instruments, percussion or brass instruments.The high-level musicians who had studied the longest performed the best on the cognitive tests, followed by the low-level musicians and non-musicians, revealing a trend relating to years of musical practice. The high-level musicians had statistically significant higher scores than the non-musicians on cognitive tests relating to visuospatial memory, naming objects and cognitive flexibility, or the brain's ability to adapt to new information.The brain functions measured by the tests typically decline as the body ages and more dramatically deteriorate in neurodegenerative conditions such as Alzheimer's disease. The results "suggest a strong predictive effect of high musical activity throughout the lifespan on preserved cognitive functioning in advanced age," the study stated.Half of the high-level musicians still played an instrument at the time of the study, but they didn't perform better on the cognitive tests than the other advanced musicians who had stopped playing years earlier. This suggests that the duration of musical study was more important than whether musicians continued playing at an advanced age, Hanna-Pladdy says."Based on previous research and our study results, we believe that both the years of musical participation and the age of acquisition are critical," Hanna-Pladdy says. "There are crucial periods in brain plasticity that enhance learning, which may make it easier to learn a musical instrument before a certain age and thus may have a larger impact on brain development."The preliminary study was correlational, meaning that the higher cognitive performance of the musicians couldn't be conclusively linked to their years of musical study. More research is needed to explore that possible link.

BEIJING, Feb. 8 (Xinhua) -- As the Chinese Lunar New Year hoilday ended Tuesday, waves of Chinese residents began their journey back to work, as they boarded trains, airplanes and buses.The China Meteorological Administration announced Tuesday that a cold front would cause temperatures to fall by 4 to 12 degrees Celsius in most parts of the country, while some areas in the northwest, north and southwest will see rainfall or snow from Wednesday to Friday.Fleets of motorbikes carrying thousands of migrant workers passed through national roads again on Tuesday.The Ministry of Public Security said it set up 8,300 service stations along the country's major highways to provide free food, medicine, and rest stops for motor-riding migrant workers. The stations also sent police cars to clear the way for large groups of motorists.Chen Tianchong, a migrant worker from Muge County, Guigang City of southwest China' s Guangxi Zhuang Autonomous Region and 38 of his fellow migrant worker started their journey on motorcycles at 4:30 a.m. on the foggy National Road 324, which is a 2,712-kilometer road linking five provinces of Fujian, Guangdong, Guangxi, Guizhou and Yunan in southern China.A motorcycle usually carried two people, often a couple, sometimes with a child sandwiched in between. They would wrap themselves in thick outerwear to battle the cold weather at night. Limited access to cheap public transportation had forced many migrant workers to make their trips home on their own."I promised my boss that I would go back to the factory in Guangdong before Wednesday," said Chen.Chen said that they might arrive at Dali County, Shunde City of south China's Guangdong Province around eleven at night, after more than 18 hours riding a motorcycle from their hometown. By this way, each family may save more than 1,000 yuan - half of their monthly income.Zhong Fei, another migrant worker also from Guangxi, chose this way home during the Spring Festival for the past three years. Zhong told Xinhua that earning money for his family was the most important thing and the exhausting trip was nothing.From Guangdong alone, one of China's manufacturing bases, over 100,000 migrant workers left for home on motorbikes, said the local police. The Spring Festival travel rush started in China in the late 1980s, when millions of farmers from inland China moved to coastal cities to work.In spite the increasing popularity of motor cycles, the majority of Chinese travelers still prefer trains or buses. Shandong province embraced the post-holiday passenger rush Tuesday, with railway stations witnessing 200,000 passengers in a single day.Highway toll booths near Beijing, Shanghai, Tianjin and other big cities in China have become clogged.Passengers are also snapping up airplane tickets. China Southern Airlines had increased flights from 30 to 70 flights per day.Official forecasts indicate that this year's Spring Festival holiday may see a record 2.85 billion passenger trips nationwide, as Chinese workers return home from across the country for family reunions and go back to work after the holidays.

BEIJING, Feb. 18 (Xinhua) -- China needs to reform funding methods for scientific and technological research in order to boost the nation's innovation capabilities, said officials and researchers attending a conference in Beijing Friday.The management of the government-funded research projects should also be reformed, State Councilor Liu Yandong said at the national conference on science and technology work.Liu stressed that reform, innovation and cooperation should be the keys for China's science and technology work over the next five years, when the government would increase funding for research in new strategic industries, such as new energy, biomedicine and high-end manufacturing.Last year, central and local government spending on science and technology development totaled 380 billion yuan (57.8 billion U.S. dollars), Science and Technology Minister Wan Gang said at the conference.Over the past five years, central government spending on science and technology development had grown by around 20 percent annually.However, some researchers have complained problems in the funding system actually hinder innovation and progress.Inflexibility in the management of government funds allowed researchers little freedom to adapt projects to developments in their fields, said Li Zhenzhen, a researcher at the Institute of Policy and Management under the Chinese Academy of Sciences (CAS).Chen Jie, a research fellow of the CAS' Institute of Microelectronics, said some authorities which oversee the spending of research funds had been rather rigid."In some cases, they are more interested in spending most of the funds on new equipment than scientists," Chen said in an earlier interview with Xinhua. "Without decent pay, it is difficult to attract top scientists to work in China.""Having to solicit and lobby for funding to support the team's research projects leaves me no more than five hours a day for real research," Chen said.Top-level scientific brains are the key to the innovative capability of China, he added.A researcher attending Friday's conference echoed Chen's opinion."China manufactures 65 percent of the world's computers. But to my knowledge, we are still spending about 150 billion U.S. dollars annually to buy computer chips from overseas," the researcher told Xinhua on condition of anonymity.Wan Gang also said imported computer chips cost China more than crude oil purchases last year.But Wan believed that with breakthroughs in frontier areas such as cloning, manned space flight, moon exploration and supercomputers, China could expect a leap in science and technology development in the near future.In October last year, China successfully launched its second lunar probe, Chang'e-2.A month later, Chinese supercomputer Tianhe-1A, which can perform 2.57 quadrillion computing operations a second, was ranked the world's fastest in the TOP500 list compiled by U.S. and European researchers.
