问题     Celebrate. Celebrate. Physicians are delighted with a Food and Drug Administration(FDA)advisory panel’s recommendation earlier this year that Vioxx and its cousins Bextra and Celebrex(all medicines known as Cox-2 inhibitors)should remain on the market, despite evidence they increase heart disease risk in some people. The panelists reached their decision after weighing all the data and concluding the benefits of these pain-relieving drugs outweighed the risks.
    Specifically, these scientists acknowledged that, for some patients, these prescription drugs were uniquely effective in reducing pain from arthritis and other causes. For others—concerned about ulcers associated with aspirin and other OTC analgesics—the Cox-2 inhibitors offered the advantage of minimizing potentially serious effects of stomach irritation.
    Now is an appropriate time for everyone to take a fresh look at the benefit-risk equation for Vioxx and the other Cox-2 inhibitors.
    The risks—increased risk of heart disease in some who use the drugs—have been well publicized. Much less publicity has been given to a spectrum of real and potential benefits that go way beyond reduced risk of stomach irritation. These little-discussed benefits would have been lost, perhaps permanently—had Vioxx, Bextra and Celebrex been driven from shelves in pursuit of perfect safety, an unattainable goal.
    For example, there is substantial evidence Cox-2 inhibitors can reduce development of colon polyps, which may become colon cancel indeed. Celebrex is FDA-approved for those genetically prone to colon cancer. Ironically, the 2004 study that revealed the elevated heart attack risk of Vioxx was primarily designed to further establish the drug’s effectiveness in protecting against colon cancer. And while the results of that interrupted trial have not yet been published, there is good reason to believe they will confirm the protective effects against colon cancer established in research over the last 10 years.
    At the time of its withdrawal from the market last fall, studies of Vioxx as well as the other Cox-2 drugs suggested they had other anti-cancer properties as well, possibly reducing the risk of malignancies of a number of sites, including the lung and esophagus.
    Had these drugs been dismissed, their untapped promise for prevention would have evaporated well before it was evaluated and applied to save lives. Fortunately, cooler and wiser heads prevailed.
Cox-2 inhibitors were once banned from the market because they were found to increase the risk of triggering______.
选项 A、colon cancer
B、stomach problems
C、heart disease
D、genetic problems
答案C
解析 题目问：Cox2抑制剂类药物曾被禁止上市是因为什么?第四段第句increased risk of heart disease in some who use the drugs，最后句perhaps permanently had Vioxx，Bextra and Celebrex been driven from shelves in pursuit of perfect safety，an unattainable goal．这两句话告诉我们，Cox2抑制剂类的药物能够增加患心脏疾病的危险，但是，通过把这些药物撤下柜台求得绝对安全是个无法实现的目标。据此可知，应该选择C。
