BEIJING, April 14 (Xinhuanet) -- Computer sales declined in the first three months of this year for the first time since 2009 worldwide.PC sales fell 1.1 percent in the first quarter to 84.3 million worldwide, according to tech research firm Gartner Wednesday, well short of its forecast for 3 percent growth.The dip was the first since the second quarter of 2009, when most of the world was still in the grip of economic turmoil."Although the first quarter is traditionally a slow one for PC sales, these shipment results indicate potential sluggishness, not just a normal seasonal slowdown," said Gartner, in a statement.Consumers select IT products at an IT fair named "Sham Shui Po computer festival" in Hong Kong, south China, Feb. 15, 2011. The eight-day IT fair kicked off here Monday. Some 600,000 people are predicted to visit the fair.Weak demand for consumer PCs was the biggest drag on the market, according to Gartner principal analyst Mikako Kitagawa."Low prices for consumer PCs, which had long stimulated growth, no longer attracted buyers," Kitagawa said."Instead, consumers turned their attention to media tablets and other consumer electronics."After Apple's second-generation iPad was released in February, many consumers either switched allegiances or simply held back from buying PCs, according to the analyst.Japan was a particularly weak spot, with PC sales falling 13 percent in the quarter, as people focused on getting back to normal after the March 11 earthquake and tsunami rather than spending money on new technology.

BRUSSELS, April 29 (Xinhua) -- As a 2004 European Union (EU) directive on herbal medicine is to be fully implemented on May 1, herbal medicinal products without a license will no longer be allowed in the EU market, the European Commission said in a press release Friday.The Traditional Herbal Medicinal Products Directive, adopted by the EU member states in 2004, introduced a so-called simplified registration procedure with a seven-year transition period for traditional herbal medicinal products to obtain a medicine license.As the transition period is to expire on Saturday, herbal medicinal products from home and abroad, most of which have been sold as food supplements for decades, need to be medically registered or authorized by EU governments in order to remain in the market after May 1.Instead of going through safety tests and clinical trials as regular chemical drugs, applicants are required by the directive to provide documents showing the herbal medicinal product is not harmful in the specified condition of use, as well as evidence that the product at least has a 30-year history of safe use, including 15 years in the EU.However, a wide range of eligibility and technical challenges along with prohibitive costs have so far prevented both local and outside herbal medicinal products from being granted the license.Only a small proportion of indigenous herbal medicinal products have been approved for registration while not a single Chinese or Indian traditional herbal medicinal products have been licensed.Lack of pan-European rules, EU member states had adopted different approaches to herbal medicine, thus creating a "state of anarchy" in the markets despite the fact that indigenous herbs had a 700-year history of use in Europe.Although the directive was intended to harmonize rules of member states and build a level-playing field across the EU, critics argued that the directive may fall short of the aim and create more chaos and uncertainties for the industry.DRAWBACKSThe directive has been under attack for being neither "adequate " nor "appropriate" due to its high registration cost for a single product and its lack of consideration about the Chinese and Indian traditional herbal medicine.Chris Dhaenens, a licensed herbalist in Belgium and a shareholder of a medium-sized herbal importing company doing business with China and ten European countries, said the directive was only appropriate for companies carrying a few products and who could afford the registration costs."It is simply inaccessible to most players distributing high- quality Chinese or Indian herbal products in Europe," he said, adding that the registration fee for a single product could be as high as 150,000 euros.The Alliance for Natural Health, a British-based group representing herbal practitioners, estimated the cost of obtaining a license at between 80,000 and 120,000 pounds (90,000 to 135,000 U.S. dollars) per herb.Dhaenens, who is also the president of the European Benefyt Foundation, a leading traditional medicine group in Europe, argued that the directive only tried to regulate herbal products instead of its practitioners and the whole herbal system, as well as fell short to take the Chinese and Indian traditional medicine into full consideration.Even the European Commission had admitted that the directive was not fit for the registration of Chinese and Indian medicine in an earlier exchange with the European Medicine Agency in Dec. 2008, Dhaenens revealed in an exclusive interview with Xinhua."But they had no money or time to work out an alternative, and so it was left to the member states," he said.

LOS ANGELES, April 2 (Xinhua) -- People taking antidepressants may be more likely to develop thicker arteries which may raise the risk of heart disease and stroke, a new study suggests.Depression can heighten the risk for heart disease, but the effect of antidepressant use is separate and independent from depression itself, according to the study make public by the American Association for the Advancement of Science (AAAS) on Saturday.The data suggest that antidepressants may combine with depression for a negative effect on blood vessels, said study first author Amit Shah, MD, a cardiology fellow at Emory University School of Medicine.Study findings will be presented on April 5 at the American College of Cardiology meeting in New Orleans, according to the AAAS.The study included 513 middle-aged male twins who both served in the U.S. military during the Vietnam War. Twins are genetically the same but may be different when it comes to other risk factors such as diet, smoking and exercise, so studying them is a good way to distill out the effects of genetics.Researchers measured carotid intima-media thickness - the thickness of the lining of the main arteries in the neck -- by ultrasound. Among the 59 pairs of twins where only one brother took antidepressants, the one taking the drugs tended to have higher carotid intima-media thickness (IMT), even when standard heart disease risk factors were taken into account.The effect was seen both in twins with or without a previous heart attack or stroke. A higher level of depressive symptoms was associated with higher IMT only in those taking antidepressants."One of the strongest and best-studied factors that thickens someone's arteries is age, and that happens at around 10 microns per year," Shah said. "In our study, users of antidepressants see an average 40 micron increase in IMT, so their carotid arteries are in effect four years older."Antidepressants' effects on blood vessels may come from changes in serotonin, a chemical that helps some brain cells communicate but also functions outside the brain, Shah said."I think we have to keep an open mind about the effects of antidepressants on neurochemicals like serotonin in places outside the brain, such as the vasculature. The body often compensates over time for drugs' immediate effects," Shah said. " Antidepressants have a clinical benefit that has been established, so nobody taking these medications should stop based only on these results. This isn 't the kind of study where we can know cause and effect, let alone mechanism, and we need to see whether this holds up in other population groups."
