1、*9The Case of the Disappearing FingerprintsOne useful anti-cancer drug can effectively erase the whorls and other characteristic marks that give people their distinctive fingerprints. Losing _1 them could become troublesome. A case released online in a letter by Annals of Oncology indicates how big
2、a _2 problem _ of losing fingerprints is.Eng-Huat Tan, a Singapore-based medical doctor describes a 62-year old man who has used capecitabine to _3 treat _ his nasopharyngeal cancer. After three years on the _4 drug._ ，the patient decided to visit U. S. relatives last December. But he was stopped by
3、 U. S. customs officials _ 5for _ 4 hours after entering the country when those officials couldnt get fingerprints from the man. There were no distinctive swirly _6 marks _ appearing from his index finger.U. S. customs has been fingerprinting incoming foreign visitors for years, Tan says. Their inde
4、x fingers are _7 printed._ and screened against digital files of the fingerprints of bad guys terrorists and potential criminals that our federal guardians have been tasked with keeping out of the country. Unfortunately, for the Singaporean traveler，one potential _8 side _ effect of his drug treatme
5、nt is a smoothing of the tissue on the finger pads. _9 Hence _ ，no fingerprints. “It is uncertain when fingerprint loss will _10 begin _ to take place in patients who are taking capecitabine，” Tan points out. So he cautions any physicians who _11 prescribe _ the drug to provide their patients with .
6、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 he，s also now got the explanatory doctors note and wont leave home _12without_ it.By
7、 the way, maybe the Food and Drug Administration, _13which_ approved use of the drug 11 years ago, should consider _14_ updating _ 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 n
8、o where _15 does._ it mention the potential for loss of fingerprints.*6Once-daily Pill Could Simplify HIV TreatmentBristol-Myers Squibb and Gilead Sciences have combined many HIV drugs into a single pill Sometimes the best medicine is more than one kind of medicine. Malaria, tuberculosis and HIV/AID
9、S,2 for example, are all treated with combinations of drugs. But that can mean a lot of pills to take. It would be simpler if drug companies combined all the medicines into a single pill, taken just once a day. Now, two companies say they have done that for people just starting treatment for HIV, th
10、e virus that causes AIDS. The companies are Bristol-Myers Squibb and Gilead Sciences. They have developed a single pill that combines three drugs currently on the market.3 Bristol-Myers Squibb sells one of them under the name of Sustiva.4 Gilead combined the others, Emtriva and Viread, into a single
11、 pill in two thousand four. Combining drugs involves more than technical issues. It also involves issues of competition if the drugs are made by different companies. The new once-daily pill is the result of what is described as the first joint venture agreement of its kind in the treatment of HIV In
12、 January the New England Journal of Medicine5 published a study of the new pill. Researchers compared its effectiveness to6 that of the widely used combination of Sustiva and Combivir. Combivir contains two drugs, AZT7 and 3TC.8 The researchers say that after one year of treatment, the new pill supp
13、ressed HIV levels in more patients and with fewer side effects.9 Gilead paid for the study. Professor Joel Gallant at the Johns Hopkins School of Medicine in Baltimore, Maryland, led the research. He is a paid adviser to Gilead and Bristol-Meyers Squibb as well as the maker of Combivir, GlaxoSmithKl
14、ine. Glaxo Smith Kline reacted to the findings by saying that a single study is of limited value. It says the effectiveness of Combivir has been shown in each of more than fifty studies. The price of the new once-daily pill has not been announced. But Gilead and Bristol-Myers Squibb say they will pr
15、ovide it at reduced cost to developing countries. They plan in the next few months to ask the United States Food and Drug Administration10 to approve the new pill. There are limits to who could take it because of the different drugs it contains. For example, pregnant women are told not to take Susti
16、va because of the risk of birth disorders.11 Experts say more than forty million people around the world are living with HIV*7Exercise Whether or not exercise adds to the length of life, it is common experience that a certain amount of regular exercise improves the health and contributes a feeling o
17、f well-being. Furthermore, exerise which involves play and recreation, and relieves nervous tension and mental fatigue in so doing, is not only pleasant but beneficial.How much and what kind of exercise one should take merits careful consideration.The growing child and the normal young man and young
18、 woman thrill with the exhilaration of strenuous sports. They fatigue to the point of exhaustion but recover promptly with a period of rest. But not so with those _of middle age and beyond. For them moderation is of vital importance. Just how much exercise a person of a given age can safely take is
19、question hard _to answer. Individual variability is too great to permit of generalization. A game of tennis may be perfectly safe for one person of forty but folly for another. The sage limit for exercise depends on the condition of the heart, the condition of the muscles, the type of exercise, and
20、the regularity with which it is taken. Two general suggestions, however, will serve as sound advice for anyone. The first is that the condition of the heart and general health should be determined periodically by careful, thorough physical examinations. The other is that exercise should be kept belo
21、w the point of physical exhaustion.What type of exercise one should choose _depens upon ones physical condition. Young people can safely enjoy vigorous competitive sports, but most older persons do better to limit themselves to less strenuous activities. Walking, swimming, skating are among the spor
22、ts that one can enjoy and safely participate in throughout life. Regularity is important if one is to get the most enjoyment and benefit out of exercise.*8 Old And ActiveIt is wellknown that life expectancy is longer in Japan than in most other countries. A recent report also shows that Japan has th
23、e longest health expectancy in the worldA healthy long life is the result of improvement in social environment.Scientists are trying to work out exactly what keeps elderly Japanese people so healthy, and whether there is a lesson to be learnt from their lifestyles for the rest of us. Should we make
24、any changes to our eating habits, for instance, or go jogging each day before breakfast? Is there some secret ingredient in the Japanese diet that is particularly beneficial to the human body?Another factor contributing to the rapid population aging in Japan is a decline in birthrateAlthough longer

26、 few younger people working and paying taxes to support themRaising the retirement age from 65 to 70 could be one solution to the problem. Work can give the elderly a sense of responsibility and mission in life. Its important that the elderly play active roles in the society and live in harmony with
27、 all generations.*10Hospital Mistreatment According to a study, most medical interns report experiencing mistreatment, including humiliation by senior doctors, being threatened, or physical abuse in their first year out of medical school.The findings come from analysis of the responses to a 13-page
28、survey mailed in January 1991 to 1, 733 second-year residents. The survey and analysis appear in the April 15th issue of the Journal of the American Medical Association. Overall, out of the 1,277 residents who completed surveys, 1,185 said that they had experienced at least one incident of mistreatm
29、ent in their intern year. In addition to reporting incidents where they were abused, more than 45% of the residents said they had witnessed at least one incident where other persons had made false medical records. Moreover, nearly three quarters of the residents said they had witnessed mistreatment
30、of patients by other residents, attending physicians, or nurses. Almost 40% said patient mistreatment was a frequent event. More than 10% of the residents said they were not allowed to have enough sleep, and the average number of hours without _ sleep was 37.6. The average on-call hours during a _ t
31、ypical week was 56.9 hours, but about 25% of the residents said their on-call assignments were more than 80 hours some weeks. Although 30% of the residents said they experienced some type of sexual harassment or discrimination, verbal abuse was the most common problem cited. When abusive incidents w
32、ere limited to events occurring three or more times, 53% of the respondents reported that they were belittled or humiliated by more senior residents, while just over 21% reported someone taking credit for their work. Being “given tasks for punishment,” “being pushed, kicked or hit,” and having someo
33、ne “threatening your reputation or career,” were reported as a more frequent occurrence by over 10% of the responding residents.*8 Old And ActiveIt is wellknown that life expectancy is longer in Japan than in most other countries.
