WASHINGTON, Nov. 16 (Xinhua) -- Supervised exercise was shown to be more effective than stenting or medication for improved walking ability in patients with peripheral artery disease (PAD), according to a U.S. study reported Wednesday at the 2011 American Heart Association Scientific Sessions meeting.The research group reported that of 111 patients studied in the randomized trial, the most effective treatment proved to be supervised exercise based on the results of a treadmill test taken at baseline and again at six months. Patients who were in the supervised exercise group improved by a mean of 4.6 minutes in the treadmill test, while the group who received stents improved by a mean of 2.5 minutes. However, researchers found that self-reported quality of life measurements proved to be higher in the group that received stents, even though their ability to walk did not improve as greatly as the group that received supervised exercise rehabilitation.The findings were published in the November issue of the journal Circulation. The researchers believe that more studies are necessary, although supervised exercise may be an effective treatment recommended for PAD patients with claudication.PAD is a condition in which plaque builds up in the arteries and affects blood flow, especially to the legs. It is estimated that between 10 and 12 million people suffer from PAD in the United States. One symptom of PAD is known as claudication, a painful cramping of the leg muscles that limits the patient's ability to walk. It affects nearly 2 million people who suffer from PAD, and results in a sedentary lifestyle and poor quality of life.Current U.S. guidelines for the treatment of claudication include pharmacotherapy, supervised exercise rehabilitation and lower extremity revascularization using stents.

TAIPEI, Dec. 10 (Xinhua) -- A televised debate among three candidates for Taiwan's next deputy leader was staged Saturday, highlighting cross-Strait political and economic issues, for next month's Taiwan leader election.The three candidates touched upon topics such as stances on the reunification of Taiwan and the Chinese mainland and the "Taiwan independence," last year's signing of the cross-Strait Economic Cooperation Framework Agreement (ECFA), among other cross-Strait issues, during the second face-to-face debate before the Jan. 14, 2012 election.Wu Den-yih, who is incumbent Taiwanese leader Ma Ying-jeou's running mate and currently chief of Taiwan's executive authority, said the signing of the ECFA aims to "help people do business and enhance Taiwan's competitiveness." Ma is seeking a second term.The ECFA did not speed up Taiwan's inclination toward the mainland market, but ensured the island's utmost interests instead, Wu said, adding that if Ma, who is also chairman of Taiwan's ruling Kuomintang (KMT) party, did not win during the upcoming election, cross-Strait peace and stability would not be maintained.However, Wu's main rival Su Jia-chyuan, the running mate of Tsai Ing-wen who campaigned for Taiwan's next leader representing major opposition Democratic Progressive Party (DPP), claimed that Taiwan is a "sovereign state" and its fate would be decided by Taiwanese themselves, no matter it would become independent or unified with the mainland, or maintain the status quo.Taiwan's future would be guaranteed only if the so-called "Taiwan consensus," put forward by Tsai, was realized, Su said during the debate.Another debater, Lin Ruey-shiung, 72, the running mate of People First Party (PFP) candidate James Soong, called for the signing of a cross-Strait peace accord, and said that the Chinese nation was fundamentally one family, with reunification benefiting both and secession hurting both.Lin said, as a member of the Chinese nation, Taiwan must be reunified with the mainland in the future, without wars, and it is the aspiration of all Taiwanese that people of both sides could freely visit each other.The three candidates also debated on anti-corruption, financial deficit and social equity.Saturday's debate among the candidates for deputy leader was the second of a three-part series. A debate of the Taiwan leader hopefuls was staged last Saturday, and they will spar again on Dec. 17.

SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.

SAN FRANCISCO, Nov. 3 (Xinhua) -- Hewlett-Packard Co. (HP) on Thursday introduced its Slate 2 Tablet PC, a business-targeted tablet computer running Windows operating system.Looking like the previous version, Slate 2, featuring an 8.9- inch screen, is upgraded with Intel Atom Z670 processor to deliver faster boot times and improved battery life up to six hours, said HP.It also has a Bluetooth keyboard dock and Swype keyboard which allows users to enter words by sliding a finger or stylus from letter to letter, lifting only between words.The device will be available to customers worldwide for 699 U.S. dollars later this month, according to HP.Slate 500, Slate 2's previous generation running Windows, was introduced last October and sold exclusively to businesses for 800 dollars upon launch.HP said in a statement that the Slate 2 tablet provides instant deployment for business and vertical markets such as education, healthcare, government and retail, where jobs frequently take users away from a traditional desk.The company on Thursday also announced HP 3115m, a new notebook PC targeting business, education and government customers. The notebook will be available in the Americas only next Friday with prices staring at 429 dollars.HP's consumer-oriented tablet TouchPad was killed off in August before former chief executive officer Leo Apotheker resigned. A dropped price from 499 to 99.99 dollars has made the unpopular device sold out in stores across the U.S. and Canada in days.Last Thursday, HP announced it will keep its PC business, saying it will build tablets running Microsoft's upcoming Windows 8 system in 2012.
