BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.

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."

SAN FRANCISCO, March 8 (Xinhua) -- Google on Tuesday released a new stable version of its Chrome web browser, which the company said is speedier, simpler and safer."With today's stable release, even your most complex web apps will run more quickly and responsively in the browser," Tim Steele, a Google software engineer, said in a blog post announcing the release.The new version of Chrome features a simpler settings page that opens in a tab rather than a dialog box, and contains a search box showing users the settings they are looking for while they type.Users can also synchronize passwords in the browser across their computers, and will be able to encrypt those passwords for extra security.Google said that the latest Chrome browser provides additional layer of protection against malicious web pages, with the extended application of sandboxing technology.The browser can be downloaded for free, and current Chrome users will be automatically updated to the new version soon, Google said.

BEIJING, Jan. 21 (Xinhua) -- Chinese Vice Premier Li Keqiang on Friday stressed the importance that local governments improve management of land and resources, as it remains vital for the stable and relatively quick development of the nation's economy.Li said China faced the difficult tasks of land and resource management as resources are becoming scarce amid the country's quickening industrialization, urbanization, and agricultural modernization.He said the nation must continue preserving arable land. To ensure grain security, China set a "red line" to guarantee its arable land never shrinks to less than 1.8 billion mu (120 million hectares).Chinese Vice Premier Li Keqiang (R) shakes hands with outstanding representatives from local departments in charge of land and resources in Beijing, capital of China, Jan. 21, 2011.Li also called on local authorities to step up efforts to protect valuable mineral resources while using resources more efficiently and in a frugal manner.At the same time, the senior Chinese official said land should be guaranteed for the nation's plan to build 10 million affordable houses for low and middle income people this year.Further, Li urged local authorities to improve work in monitoring and taking precautionary measures against geological disasters to ensure the safety of people's lives and property.

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.
