WASHINGTON, Nov. 21 (Xinhua) -- The use of acupuncture for children is common and acupuncture is generally safe for children when performed by "appropriately trained practitioners," Canadian researchers reported Monday in online journal Pediatrics.Researchers at the University of Alberta looked at data from 37 studies of needle acupuncture, spanning 60 years, on children from birth to age 17, and assessed the association between needle acupuncture and various levels of adverse events in children. They found that of 279 adverse events identified, 253 were mild, one was moderate and 25 were serious.Serious side effects included bleeding, infections, and heart and lung problems. One child may have contracted HIV. But the researchers said the serious side effects were related to substandard conditions from the care provider, rather than acupuncture's technique itself. They concluded that in trained hands, pediatric acupuncture is safe.Acupuncture has been around for thousands of years, and traditional Chinese theory suggests needle placement helps balance the body's energy flow, called "qi". Acupuncture is sometimes used to treat headaches, migraines, back and joint pains, cramps, and chemotherapy-induced nausea. Estimates show 150,000 U.S. children undergo acupuncture each year.

SAN FRANCISCO, Jan. 26 (Xinhua) -- Global tablet shipments reached nearly 27 million units in the fourth quarter of 2011 with Android jumping to a record share of 39 percent, said a new research released on Thursday.According to the research by consulting firm Strategy Analytics, global tablet shipments reached a record high of 26.8 million units in the last quarter of 2011, surging 250 percent from 10.7 million units in the same period a year earlier.Android captured a record 39 percent share of global tablet shipments, rising from 29 percent in the year-ago quarter.Global Android tablet shipments tripled annually to 10.5 million units in the last three months of 2011 and the platform so far is relatively popular with tablet manufacturers, said the research.However, Apple shipped 15.4 million iPads worldwide and maintained its market leadership with 58 percent share during the fourth quarter last year."Apple shrugged off the much-hyped threat from entry-level Android models this quarter," Peter King, director at Strategy Analytics, said in a statement.The research found Microsoft captured a mere 1.5 percent global tablet share in the quarter, noting that "the upcoming release of Windows 8 this year cannot come quickly enough for Microsoft, so its hardware partners can start competing more effectively in the tablet space."In the full year of 2011, global tablet shipments hit 66.9 million units, increasing by 260 percent from 18.6 million units in 2010, according to the research.Consumers are increasingly buying tablets in preference to netbooks and even entry-level notebooks or desktops, said the research.

SAN FRANCISCO, Nov. 1 (Xinhua) -- Apple announced on Tuesday that its latest iPhone 4S smartphone will be available in China's Hong Kong, South Korea and 13 additional countries next Friday.Customers will be able to pre-order iPhone 4S beginning this Friday, the Cupertino, California-based company said in a statement.The other 13 countries are Albania, Armenia, Bulgaria, El Salvador, Greece, Guatemala, Malta, Montenegro, New Zealand, Panama, Poland, Portugal and Romania.So far, some owners have been complaining about the shorter battery life on their new iPhone 4S handsets. Apple is reportedly investigating the issue and has not made official comments yet.The iPhone 4S looks the same as the previous iPhone 4 but has major hardware upgrade inside. Apple announced sales of more than four million units of iPhone 4S in the three days after its launch in the United States on Oct. 14.The iPhone 4S now is available in 29 countries and is expected to arrive in stores in more than 70 countries by the end of this year.

SHIJIAZHUANG, Dec. 3 (Xinhua) -- More than 3.48 million people in rural areas of north China's Hebei Province have been given access to safe drinking water this year, a local official said Saturday.Authorities in the province have invested more than 1.7 billion yuan (270 million U.S. dollars) so far in 2011 in building drinking water infrastructure, said Liang Jianyi, deputy director of the Hebei Provincial Department of Water and Resources.More than 32 million rural people in Hebei, especially in mountainous and coastal areas, had long suffered from unsafe water, with problems including high fluorine and alkaline contents, Liang said.From 2005 to 2010, the provincial authorities put almost 6 billion yuan into providing safe drinking water for 13 million rural residents, he added.

BEIJING, Oct. 24 (Xinhuanet) -- Thirty-year-old Chen Liang acquired his iPhone 4S in a relatively straightforward way without visiting the gray market. He typed "Looking for an iPhone 4S through weibo" on the Chinese equivalent of Twitter at 9 am on Oct 17 and secured one by 2 pm that day.The software engineer was lucky. Thousands of Chinese Apple fans are desperate for the 4S regardless of the price and effort required after China was left out of Apple's list of first and second groups of countries where it launched its latest product."A friend's friend in Canada put me in contact with a supplier and I'm getting one for just 5,500 yuan (9). Unauthorized Apple retailers are setting their floor price at 8,000 yuan," said Chen, from Jiangsu province.A proud Apple customer shows off the new iPhone 4S he purchased at an Apple store in Munich, Germany."I need to have one because I see the potential of its cloud computing service and artificial intelligence application. That's currently a wide open area in China. Simply speaking, other smartphones allow you to access search engines while the 4S's cloud search using Siri - a voice recognition and talking assistant - helps to filter irrelevant results and makes suggestions for you. My work-related curiosity drove me to get one because it is the future for phones."Jin Jianhan, who works at a Shanghai-based IT company, says he will do whatever it takes to get a 4S because "it's very important to get an Apple product when it's first launched".Jin plans to contact his friends in the United States to see whether they can send him one and to keep an eye on the Hong Kong market in case the special administrative region gets the green light to sell the devices in the third round of agreements."I'd try both ways and go for the overseas one first even it won't cover my domestic Apple guarantee," said Jin. "I will take the Hong Kong 4S when it's available to replace the American one."In its first round of agreements, Apple launched the iPhone 4S in the United States, Canada, Australia, the United Kingdom, France, Germany and Japan. Apple said on Oct 17, the third day after its release, that more than four million iPhone 4S devices had been sold. That figure is more than double the 1.7 million units of the iPhone 4 that Apple sold during its first three days on the market in June last year.The second group of countries to be licensed were mostly other European states. They will get the product by the end of October. Apple China refused to give a date for when it will be sold on the mainland.Meanwhile, Apple fans all over the world are paying their respects to Apple guru Steve Jobs by snapping up the iPhone 4S in record numbers. Wang Bo, who works as an industrial designer in Sydney, Australia, reserved his at a local store."It's the last Apple product that he (Steve Jobs) ever worked with," said Wang. "I'm buying it as a souvenir."In Huaqiangbei, an area in Shenzhen known for its many consumer electronics shops, unauthorized Apple dealer Zhou Bin has been happy to work overtime since the night of Oct 15, the first day that he received supplies of the iPhone 4S.
