BEIJING, July 25 (Xinhuanet) -- More than one in three births in the U.S. are  delivered by C-section, which is an all time high and an increase of 25 percent over seven years, according to news reports Monday quoting a new study.Based on data from 19 states, C-section, or Cesarean, deliveries shot up from 27 percent of all births in 2002 to 34 percent in 2009, said the study by HealthGrades.  HealthGrades is an independent health care ratings organization with information on physicians, dentists and 5,000 hospitals in the nation.The study noted that the states with the highest rates are Texas, New Jersey and Florida while Utah, Colorado and Wisconsin are the lowest.Experts hold C-section deliveries are most suitable when vaginal delivery puts the health of the woman or child at risk, but also attributing the reason of increase to convenience, less risk, fertility and general attitudes.However, Divya Cantor, MD, MBA and HealthGrades Senior Physician Consultant. cautioned, "C-sections are rising, and there needs to be a little bit more scrutiny from the person who is having the C-section as well as doctors and hospitals."

BEIJING, Sept. 28 (Xinhua) -- Chinese banks have extended more loans to small firms to ease their financial predicaments as the government tightens monetary supply, a banking regulator said Wednesday.Outstanding loans to small firms grew 26.6 percent year-on-year to hit 9.85 trillion yuan (1.55 trillion U.S. dollars) at the end of July, said Xiao Yuanqi, an official in charge of financial services for small enterprises at the China Banking Regulatory Commission.The growth was 10 percentage points higher than that of the banks' total outstanding loans, Xiao told Xinhua.More than 100 commercial banks have set up special operations to ease small firms' difficulties getting access to bank credit, he noted.The figures came at a time when China is trying to balance the missions of countering inflation and sustaining the growth of small enterprises.The People's Bank of China, or the central bank, has raised the benchmark interest rate three times this year and increased the reserve requirement ratio six times.The measures bit into small, cash-strapped companies, which are already disadvantaged in seeking bank support due to insufficient collateral.Only 15 percent of China's small enterprises could get loans from banks and half of them had to resort to private lenders, according to a report by the National School of Development with Peking University in July.With tighter liquidity and stricter regulatory requirements on capital-adequacy ratios and loan-deposit ratios, banks are more reluctant to lend to small firms, said Ai Min, a retail banking general manager with China Minsheng Banking Corp., Ltd.Besides, the expanding size of lending to small firms may lead to higher risks, said Ai.He suggested banks improve the risk evaluation and collateral system for loans to small firms.

MOSCOW, Aug. 6 (Xinhua) -- The Arctic is getting warmer at a fast pace with the Russian Arctic sector's ice areas contracting to historically low levels, according to Russian meteorological bureau Rosgidromet.According to a Rosgidromet report cited by Itar-Tass news agency Saturday, the polar cap in the Russian sector has shrunk to the historical low registered in 2007, with no ice expected to block the Northern Seaway at least until September."Currently, Arctic navigation conditions are very favorable. By early August, navigation can be done without icebreakers almost along the entire route," said Valery Martyshchenko, head of Rosgidromet's environment pollution monitoring department.According to the Arctic and Antarctic Research Institute, the current ice cover in the Arctic Ocean is 6,860 million square kilometers, way below average.Martyshchenko said the longer period of icebreaker-free navigation would benefit the regions located in the Arctic area, allowing longer access to food and energy supplies, but the warming of the climate also posed new threats, such as melting of ice and forming of icebergs.

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 18 (Xinhua) -- U.S. scientists have proven that oncogenes can change normal cells into stem-like cells, paving the way to a safer and more practical approach to treating diseases like multiple sclerosis and cancer with stem cell therapy.In a collaborative study, researchers from the Keck School of Medicine of the University of Southern California (USC), and the Children's Hospital of Orange County (CHOC) in California and Good Samaritan Hospital Medical Center in New York have successfully converted human skin cells into brain cells by suppressing the expression of p53, a protein encoded by a widely studied oncogene. This suggests that p53 mutation helps determine cell fate -- good or bad -- rather than only the outcome of cancer.Oncogenes are generally thought to be genes that, when mutated, change healthy cells into cancerous tumor cells.Study findings were appearing Monday on the website of the American Association for the Advancement of Science (AAAS)."The reality may be more complicated than people think," said Jiang F. Zhong, Ph.D., assistant professor of pathology at the Keck School. "What is a stem cell gene? What is a cancer gene? It may be the same thing.""When you turn off p53, people think the cell becomes cancerous because we tend to focus on the bad thing," Zhong said. "Actually, the cell becomes more plastic and could do good things, too. Let's say the cell is like a person who loses his job (the restriction of p53). He could become a criminal or he could find another job and have a positive effect on society. What pushes him one way or the other, we don't know because the environment is very complicated."Stem cells can divide and differentiate into different types of cells in the body. In humans, embryonic stem cells differentiate into three families, or germ layers, of cells. The reasons why and how certain stem cells differentiate into particular layers are not clearly understood. However, from those layers, tissues and organs develop. The endoderm, for example, leads to formation of the stomach, colon and lungs, while the mesoderm forms blood, bone and heart tissue. In its study, Zhong's team examined human skin cells, which are related to brain and neural cells from the ectoderm.When p53 was suppressed, the skin cells developed into cells that looked exactly like human embryonic stem cells. But, unlike other man-made stem cells that are "pluripotent" and can become any other cells in the body, these cells differentiated only into cells from the same germ layer, ectoderm."IPSCs (induced pluripotent stem cells) can turn into anything, so they are hard to control," Zhong said. "Our cells are staying within the ectoderm lineage."Zhong said he expects that suppressing other oncogenes in other families of cells would have the same effect, which could have critical significance for stem cell therapy. Future research should focus on determining which genes to manipulate, Zhong said.The study is slated to appear in the Proceedings of the National Academy of Sciences later this month, according to AAAS.
