WASHINGTON, Sept. 15 (Xinhua) -- The rates of new lung cancer cases in the United States dropped among men in 35 states and among women in six states between 1999 and 2008, according to a report released Thursday by the Centers for Disease Control and Prevention (CDC).Among women, lung cancer incidence decreased nationwide between 2006 and 2008, after increasing steadily for decades.The decrease in lung cancer cases corresponds closely with smoking patterns across the nation, the report said. In the West, where smoking prevalence is lower among men and women than in other regions, lung cancer incidence is decreasing faster. Studies show declines in lung cancer rates can be seen as soon as five years after smoking rates decline.The report also noted that states that make greater investments in effective tobacco control strategies see larger reductions in smoking; and the longer they invest, the greater the savings in smoking -- related health care costs. Such strategies include higher tobacco prices, hard-hitting media campaigns, 100 percent smoke-free policies, and easily accessible quitting treatments and services for those who want to quit."Although lung cancer among men and women has decreased over the past few years," said CDC Director Thomas Frieden in a statement. "too many people continue to get sick and die from lung cancers, most of which are caused by smoking. The more we invest in proven tobacco control efforts, the fewer people will die from lung cancer."Lung cancer is the most commonly diagnosed cancer, and the leading cause of cancer death in the United States. Cigarette smoking and exposure to secondhand smoke cause most lung cancer deaths in the United States.

GENEVA, Sept. 26 (Xinhua) -- Two million people worldwide are estimated to die from air pollution each year, the Geneva based World Health Organization (WHO) said in its air quality report published on Monday.According to data collected by the WHO from nearly 1,100 cities across 91 countries, elevated level of fine particle pollution, which could cause heart diseases, lung cancer, asthma and acute lower reparatory infections, are common across many urban areas, with some cities registering fine particle pollution levels 15 times as much as the WHO guidelines.For both developed and developing countries, the biggest contributors to urban outdoor air pollution include motor transport, small-scale manufacturers and other industries, burning of biomass and coal for cooking and heating, as well as coal-fired power plants.Residential wood and coal burning for space heating is said to be an important contributor to air pollution, especially in rural areas during colder months, the WHO report said.

BEIJING, August 23 (Xinhuanet) -- In the U.S., the rate of injuries related to children and teens falling out of windows declined over a 19-year period, although not nearly as fast as in some cities with comprehensive prevention programs, researchers found.From 1990 to 2008, the overall rate of injuries in children and teens was 7.3 per 100,000 per year, going as high as 11.4 in 1992 and as low as 5.8 in 1999, according to Gary Smith, MD, DrPh, of the Research Institute at Nationwide Children's Hospital in Columbus, Ohio, and colleagues.The annual rate of injuries fell slightly but significantly over the study period, driven entirely by a reduction of 0.426 cases per 100,000 per year in children up to age four, the researchers reported online ahead of the September issue of Pediatrics.That is much less than the reduction seen in previous studies of fall prevention programs in New York City and Boston, which achieved declines of up to 96 percent during a 10-year period through education, increased access to window guards, and a mandate to use window guards in certain homes (only in New York City)."The slower decrease followed by a plateau in injury rates found in this study underscores the fact that prevention efforts of the magnitude undertaken in New York and Boston have not occurred nationwide," Smith and hiscolleagues wrote.The researchers also acknowledged that the study underestimated the number of injuries related to falling out of a window because it included only those children treated in emergency rooms. An additional limitation is that the case narratives often lacked details about the circumstances surrounding the injury, including any suicidal intent.

VANCOUVER, Sept. 18 (Xinhua) -- At the fourth International Qigong Tournament and Exchange currently going on in Vancouver, many of the competitors spoke Sunday of how the practice had improved their lives after being able to overcome the complications of illness and injury.While many of the more than 300 competitors in the eight-day tournament were out to demonstrate they were among the best practitioners in the world, others were clearly happy to be competing after previously living with various ailments that had affected their mobility and overall way of life."I've been very ill," said competitor Felicia Kazmer of the New Jersey-based U.S. Health Qigong Association. "I have Lyme disease and infections. I was out on medical for six months last year and through the practice of Qigong, and especially the intense practice because I knew we were coming to the tournament, I am feeling better than I have in years and years. I know that this has opened the meridians and allowed the qi to flow and it's worked better than any drug."While Qigong has been practiced in China for centuries, it is relatively new to the outside world. It is for this reason that after holding the biennial International Qigong Tournament and Exchange in China on the first three occasions, the event was moved abroad for the first time to help increase its awareness and growing popularity.Altogether, 44 Health Qigong teams are in Canada from 25 nations and regions for the tournament.Philip Moot, a 26-year-old from The Hague, was attending the tournament for a second time after taking in the last competition in Shanghai in 2009. Now studying Chinese acupuncture, the Dutchman said he took up Qigong after suffering from Pfieffer, a glandular fever that is a fatigue illness."I was always tired and when I woke up in the morning I felt already tired. Then I started with Qigong and exercises and it improved my health enormously. I'm doing it now, I think four years, and it made me stronger. The tiredness is gone."Moot said the more you put into Qigong, a series of movements and postures that focuses on regulated breathing techniques, focused meditation and self-massage, the more a person will get out of it.He compared the practice to charging up a battery and added he had now turned his parents on to Qigong, as well as a friend's father who is battling cancer. "It's helping him also to relieve the pain a little and not to think constantly of this disease."According to various clinical studies, the regular practice of Qigong has shown to be beneficial in reducing stress, better balance, lowering blood pressure, enhancing the immune system, improving sleep patterns, as well as improved cardiovascular, respiratory, circulatory and digestive functions, among many others.Depending on who you talk to, the benefits of Health Qigong means different things to different people, according to practitioner Susan Gallin. The New Jersey nurse took up the practice 18 months ago after undergoing knee surgery."But after the surgery my knee was never back to normal. So someone suggested to take Qigong," she said. "And I started taking it and it was amazing. I guess maybe after a couple of months my knee started to feel better and I'm not 100 per cent right now, but I do really well. I can squat down, things I couldn't do before the surgery."Working in the medical industry, Gallin said she was at odds with the western mentality of taking pills for everything. She felt hospitals should offer more wellness programs than they do."Some of the hospitals in the United States offer such things that include this type of alternative medicine, but I don't think it's enough. Some of the bigger pharmaceutical companies offer wellness programs before the hospitals and you would think we are in a healthcare system that they would offer a wellness (program), try to keep you well so you don't get sick. I know for myself I always try to do whatever I can before I take a pill."Reg Carter knows what it is like to endure a steady diet of pills after having to take anti-inflammatories and painkillers for problems with his joints. For the past two years the native Derby, England, has been practicing Qigong and was in Vancouver as part of the British team taking part."I had shoulder injuries, a broken collarbone, arthritis of several joints, elbows, my hands, fingers and the mobility has improved considerably since I've been doing the Qigong. The mobility has improved and also with the strengthening through the lower body and legs. The back injuries has improved. I don't get so much pain and I find I can move about a lot more fluidly," he said."I just feel like I've had a lot more life balance. I feel a lot more calmer. My sleep pattern's improved. I don't get angry so often, and if I do I find that I can get to grips with it and keep a lot calmer."Toronto resident Karen Widmer has never endured the pain suffered by Carter, but credits the energy of Qigong in aiding the recovery of a broken wrist she suffered four years ago while studying a level one Qigong course.Through regular practice, Qigong practitioners are said to be able to direct the energy in the body, the qi, towards the limbs."I completed it (the course) with a broken wrist and I could feel the energy repair much faster and the recovery time was better than they had actually thought," said the yoga instructor.Now totally hooked on Health Qigong and with 5,000 hours of practice to her credit, the 50-something Widmer explains it takes 10,000 hours of practice to achieve the title of "master.""While it looks like a physical process, it's actually very much more a spiritual process. Since we are electro-magnetic beings, it makes sense that we could send that current around in a positive way. But it does lead a person to longevity. It's a wellness that is authentic and I hope to be 100 years old and still doing it," she said."I have always enjoyed movement knowing that movement is health. And I would say that even people who aren't athletic can do this. It helps balance. Balance prevents falls, which prevents breakage. It is very beneficial to do this."

LOS ANGELES, July 6 (Xinhua) -- NASA scientists have got the first-ever, up-close details of a Saturn storm that is eight times the surface area of Earth, the Jet Propulsion Laboratory ( JPL) announced on Wednesday.The images were captured by NASA's Cassini spacecraf, according to JPL in Pasadena, Los Angeles.On Dec. 5, 2010, Cassini first detected the storm that has been raging ever since. It appears approximately 35 degrees north latitude of Saturn.The storm is the biggest observed by spacecraft orbiting or flying by Saturn. NASA's Hubble Space Telescope captured images in 1990 of an equally large storm.Pictures from Cassini's imaging cameras show the storm wrapping around the entire planet covering approximately two billion square miles (4 billion square kilometers).The storm is about 500 times larger than the biggest storm previously seen by Cassini during several months from 2009 to 2010. At its most intense, the storm generated more than 10 lightning flashes per second.Cassini has detected 10 lightning storms on Saturn since the spacecraft entered the planet's orbit.Those storms rolled through an area in the southern hemisphere dubbed "Storm Alley." "Cassini shows us that Saturn is bipolar," said Andrew Ingersoll, a Cassini imaging team member at the California Institute of Technology in Pasadena, California. "Saturn is not like Earth and Jupiter, where storms are fairly frequent. Weather on Saturn appears to hum along placidly for years and then erupt violently. I'm excited we saw weather so spectacular on our watch."The new details about this storm complement atmospheric disturbances described recently by scientists using Cassini's composite infrared spectrometer and the European Southern Observatory's Very Large Telescope. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's JPL manages the mission for the agency's Science Mission Directorate in Washington.
