ABUJA, Jan. 28 (Xinhua) -- China and Nigeria celebrated the 40th anniversary of the establishment of diplomatic relations on Thursday evening in Nigeria's capital city Abuja.More than 600 Chinese and Nigerian guests, including Nigeria's former Head of State Yakubu Gowon, attended the gala event.On Feb. 10, 1971, the two most populous developing countries in Asia and Africa set up their diplomatic relations, said Deng Boqing, the Chinese ambassador to Nigeria.The frequent high level visits from both sides built up the mutual trust, the exchanges and cooperation in the fields of economy, culture, science, education and health, he said.The bilateral trade volume in 2010 is expected to break the record 7.5 billion U.S. dollars in 2008. The total Chinese investment in Nigeria has been nearly 8 billion dollars by the end of 2010, he said.Deng also gave tribute to the indispensable efforts made by the overseas Chinese and Chinese companies in Nigeria.Yakubu Gowon, former head of state in the 1970s, told Xinhua that he was delighted to witness the establishment of diplomatic ties between China and Nigeria in 1971 during his term. He visited China and met the late Chinese leader Mao Zedong in 1974.Nigeria's President Goodluck Jonathan sent his representative to the celebration of the 40th anniversary of bilateral ties, pledging the two countries would work closely in the future.

BEIJING, Feb. 27 (Xinhua) -- Chinese Premier Wen Jiabao said during an online chat with netizens here Sunday that the government is striving to ensure that the people live a comfortable life with security and confidence in the period of 2011-2015.China's development blueprint for the coming five years will place high emphasis on the efforts to improve the people's livelihood, Wen said.To enhance the people's living standards is "our work's starting point as well as the final aim," he said.Greater efforts will be made to boost social development and progress, especially in those key sectors and aspects concerning national development and mass interests, the premier said.Wen began his online chat with netizens at 9 a.m. Sunday jointly hosted by the central government website (www.gov.cn) and Xinhua News Agency website (www.news.cn).

WASHINGTON, May 3 (Xinhua) -- People diagnosed with asthma in the United States grew by 4.3 million between 2001 and 2009, according to a new report released Tuesday by the Centers for Disease Control and Prevention (CDC).In 2009, nearly one in 12 Americans were diagnosed with asthma. In addition to increased diagnoses, asthma costs grew from about 53 billion U.S. dollars in 2002 to about 56 billion dollars in 2007, about a six percent increase. The explanation for the growth in asthma rates is unknown, according to the CDC.Asthma is a lifelong disease that causes wheezing, breathlessness, chest tightness, and coughing, though people with asthma can control symptoms and prevent asthma attacks by avoiding things that can set off an asthma attacks, and correctly using prescribed medicine, like inhaled corticosteroids. The report highlights the benefits of essential asthma education and services that reduce the impact of these triggers, but most often these benefits are not covered by health insurers."Despite the fact that outdoor air quality has improved, we've reduced two common asthma triggers -- secondhand smoke and smoking in general -- asthma is increasing," said Paul Garbe, chief of CDC 's Air Pollution and Respiratory Health Branch. "While we don't know the cause of the increase, our top priority is getting people to manage their symptoms better."Asthma triggers are usually environmental and can be found at school, work, home, outdoors, and elsewhere and can include tobacco smoke, mold, outdoor air pollution, and infections linked to influenza, cold-like symptoms, and other viruses.According to the report, asthma diagnoses increased among all demographic groups between 2001 and 2009, though a higher percentage of children reported having asthma than adults (9.6 percent compared to 7.7 percent in 2009). Annual asthma costs in the United States were 3,300 dollars per person with asthma from 2002 to 2007 in medical expenses. About two in five uninsured and one in nine insured people with asthma could not afford their prescription medication."Asthma is a serious, lifelong disease that unfortunately kills thousands of people each year and adds billions to our nation's health care costs," said CDC Director Thomas Frieden. "We have to do a better job educating people about managing their symptoms and how to correctly use medicines to control asthma so they can live longer more productive lives while saving health care costs."

GENEVA, March 28 (Xinhua) -- The world is ill-prepared to respond to a severe influenza pandemic or to any similarly global, sustained, and threatening public health emergency, an independent expert-committee entrusted by World Health Organization (WHO) said at its fourth meeting here on Monday.The Review Committee, tasked to look into the experience gained in the global response to the influenza A (H1N1) pandemic in 2009, issued its preliminary report at the meeting.In the report, the Committee said, "global preparedness can be advanced through research, strengthened health-care delivery systems, economic development in low and middle-income countries and improved health status."It recommended that international society establish an extensive global public health reserve corps consisted of experts and public health professionals, which could be deployed to support countries in need, in case of future pandemics.Another suggestion was to create a contingency fund for public health emergencies to be held in trust at an institution such as the World Bank, in order to provide financial support during a declared public health emergency of international concern.The report also urged WHO member states to reach an agreement on sharing of viruses and access to vaccines, and encouraged them to run independent or cooperative influenza research program.WHO Director-General Margaret Chan said at the opening of the meeting that the report had offered "critical guidance to all ministers of health who need to make far-reaching decisions."She said the recommendations in the report would help to " improve the capacity of WHO and the international community to respond to public health emergencies" and therefore should be taken with "added urgency."In January 2010, WHO's Executive Board established a Review Committee, at Chan's proposal, to review the experience gained in response to the H1N1 pandemic, as well as the International Health Regulations and WHO's functioning in tackling the disease.The Committee is expected to prepare its final report out of the current preliminary version, and submit it to the decision- making body of WHO in May.

WASHINGTON, May 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced Wednesday that its Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein's general theory of relativity, which the spacecraft was designed to test.The experiment, launched in 2004, used four ultra-precise gyroscopes to measure the hypothesized geodetic effect, the warping of space and time around a gravitational body, and frame- dragging, the amount a spinning object pulls space and time with it as it rotates.GP-B determined both effects with unprecedented precision by pointing at a single star, IM Pegasi, while in a polar orbit around Earth. If gravity did not affect space and time, GP-B's gyroscopes would point in the same direction forever while in orbit. But in confirmation of Einstein's theories, the gyroscopes experienced measurable, minute changes in the direction of their spin, while Earth's gravity pulled at them.The findings are available online in the journal Physical Review Letters."Imagine the Earth as if it were immersed in honey. As the planet rotates, the honey around it would swirl, and it's the same with space and time," said Francis Everitt, GP-B principal investigator at Stanford University. "GP-B confirmed two of the most profound predictions of Einstein's universe, having far- reaching implications across astrophysics research."GP-B is one of the longest running projects in NASA history, with agency involvement starting in the fall of 1963 with initial funding to develop a relativity gyroscope experiment. Subsequent decades of development led to groundbreaking technologies to control environmental disturbances on spacecraft, such as aerodynamic drag, magnetic fields and thermal variations. The mission's star tracker and gyroscopes were the most precise ever designed and produced.GP-B completed its data collection operations and was decommissioned in December 2010."The mission results will have a long-term impact on the work of theoretical physicists," said Bill Danchi, senior astrophysicist and program scientist at NASA Headquarters in Washington. "Every future challenge to Einstein's theories of general relativity will have to seek more precise measurements than the remarkable work GP-B accomplished."
