完形填空Fingerprints
One useful anti-cancer drug can effectively erase the whorls and other characteristic matrks that give people their distinctive fingerprints. Losing 1 could become troublesome. A case released online in a letter by Annals of Oncology indicates how big a 2 of losing fingerprints is.
Eng-Huat Tan， a Singapore-based medical doctor describes a 62-year old man who has used capecitabine to 3 his nasopharyngeal cancer. After three years on the 4 ， the patient decided to visit U. S. relatives last December. But he was stopped by U.S. customs officials 5 4 hours after entering the country when those officials couldnt get fingerprints from the man. There were no distinctive swirly 6 appearing from his index finger.
U.S. customs3 has been fingerprinting incoming foreign visitors for years， Tan says. Their index fingers are 7 and screened against digital files of the fingerprints of bad guys — terrorists and potential criminals — at our federal guardians have been tasked with keeping out of the country. Unfortunately， for the Singapore traveler， one potential 8 effect of his drug treatment is a smoothing of the tissue on the finger pads. 9 ， no fingerprints.
"It is uncertain when fingerprint loss will 10 to take place in patients who are taking capecitabine，" Tan points out. So he cautions any physicians who 11 the drug to provide their patients with a doctors note pointing out that their medicine may cause fingerprints to disappear.
Eventually， the Singapore traveler made it into the United States. I guess the name on his passport didnt raise any red flags. But hes also now got the explanatory doctors note—and wont leave home 12 it.www.zcyy8.com
By the way， maybe the Food and Drug Administration， 13 approved use of the drug 11 years ago， should consider 14 its list of side effects associated with this medicine. The current list does note that patients may experience vomiting， stomach pain and some other side effects. But no where 15 it mention the potential for loss of fingerprints.

指紋消失事件
一種非常有效的抗癌藥物能夠清除籮狀指紋和其他使指紋與眾不同的標(biāo)志。失去指紋可是會(huì)有很大麻煩。一個(gè)被腫瘤學(xué)年報(bào)在網(wǎng)上公布的信件中說(shuō)明了失去指紋會(huì)帶來(lái)多大麻煩。
Eng-Huat Tan，一個(gè)新加坡籍的醫(yī)學(xué)博士描述了一位用卡培他濱治療鼻咽癌62歲老人的經(jīng)歷。經(jīng)過(guò)這個(gè)藥物三年的治療后，這位病人去年十二月份決定去美國(guó)拜訪親戚。在他進(jìn)入這個(gè)國(guó)家后，他被美國(guó)海關(guān)人員攔截了四小時(shí)之久，因?yàn)檫@些官員無(wú)法從他身上獲取指紋。因?yàn)樵谒氖持干蠜](méi)有旋渦狀的指紋標(biāo)記。
美國(guó)海關(guān)數(shù)年以來(lái)一直都會(huì)采集來(lái)訪外國(guó)人的指紋，Tan說(shuō)。他們的食指指紋被采集并且和那些壞人的指紋進(jìn)行數(shù)字化資料檔案比對(duì)——我們的聯(lián)邦衛(wèi)士的職責(zé)是要把那些恐怖份子和疑似罪犯檔在國(guó)門之外。不幸的是，對(duì)于這位新加坡旅行者來(lái)說(shuō)，藥物治療的一個(gè)潛在的副作用就是會(huì)使指尖上的肉墊組織變光滑，也就是說(shuō)沒(méi)有指紋。
“對(duì)于服用卡培他濱的病人來(lái)說(shuō)，指紋何時(shí)會(huì)消失是不確定的。”Tan指出。所以他警告每位醫(yī)師在給病人開(kāi)藥時(shí)要給病人開(kāi)具他們的藥物可能會(huì)使指紋消失的證明單。
最終，那位新加坡旅客終于進(jìn)入了美國(guó)。我猜想他護(hù)照上的名字沒(méi)有帶有任何危險(xiǎn)信號(hào)。但是他同樣要帶有醫(yī)師開(kāi)的證明單——并且要隨身攜帶。
順便提一下，美國(guó)食品和藥物局已經(jīng)準(zhǔn)許這一藥物的使用有11年之久了，應(yīng)該考慮更新該藥物的副作用清單。現(xiàn)有的副作用清單中確實(shí)列出病人會(huì)經(jīng)歷嘔吐、胃痛和其他副作用，但是卻沒(méi)有提及失去指紋的潛在危險(xiǎn)。
