8、ers(媒人 ) have always known that not being married is a definite health hazard. But when a team of researchers from the University of California, San Francisco, reported a few weeks ago that middle-aged (中年的 ) men without wives were actually twice as likely to die during a 10-year span(全长 ) as men wi

9、th wives, the espoused and the spouseless alike stopped to take notice. It was the kind of news that swept through offices and watering holes-and it made people feel smug(自鸣得意的 ) or anxious, depending on their circumstances. Now the researchers who conducted the study are trying to find out what acc

10、ounted for(说明 ,解释 ) the dramatic differences in survival rates. The investigators, headed by UCSF associate professor of epidemiology arid biostatistics(生物统计学 ) Maradee A. Davis, had set out to examine the effect of various living arrangements on mortality. Because of the buffering social support ma

11、rriage is known to provide, Davis and her colleagues fully expected to find that men and women dwelling alone fared(生活 ,进展 ) worst in survival rates. It came as some surprise, however, that in their study population, subjects who shared living quarters with people other than a spouse had the same lo

12、wer survival rates as those who lived by themselves. “The critical factor, “Davis says, “seems to be the presence of a spouse.“ The lower survival rates for the spouseless were found primarily in men who were widowed, separated or divorced, rather than in those who had never been married. Davis and

13、her colleagues have already eliminated certain health factors as causes of higher mortality by adjusting their data to discount the effects of smoking, alcohol consumption, obesity and lack of exercise. Now they will look more closely at a variety of other considerations, such as blood pressure, cho

14、lesterol levels and chronic illnesses. Sex roles: While many middle-aged men now know the difference between a cheese grater and a garlic press, nutrition may still account for some of the California studys findings. Previous research by Daviss team showed that unmarried men even if they lived with

15、other people ate less healthy diets than married men. “Traditional sex roles have meant that men arent as well informed as women about nutritional shopping and food preparation. “says Davis. Emotional and social factors probably also played a role in higher mortality among the spouseless men. The Sa

16、n Francisco researchers will examine a randomly selected subgroup of their study population for more detailed medical data, and theyll look at a trait(特征 ) they call “general well-being. “This focuses on subjectively reported feelings and moods, rather than specific psychological symptoms. The resea

17、rchers will analyze questionnaires that asked how frequently the men felt worried, nervous or poorly rested. But the team will also look at the causes of death; if the men without wives show higher rates of suicide or fatal accidents, its likely that emotional stress contributed to(可助于 , 促使 )their h

18、igher mortality rate. Davis has already discovered that the married men reported a significantly higher level of well-being than those who werent married. So perhaps the explanation for their longer survival isnt really so complicated. Because they are cared for by nurturing wives, they just plain f

19、eel happier than the other guys do. And what better reason than for staying alive? 16 Environmental factors affect our health in important way. （ A） Right （ B） Wrong （ C） Not mentioned 17 The various living arrangements wont affect mortality. （ A） Right （ B） Wrong （ C） Not mentioned 18 Nutrition is

AIDS is the final, life-threatening stage of infection with human immuno-deficiency virus(HIV). AIDS stands for acquired immuno-deficiency syndrome. The name refers to the fact that HIV seve

23、rely damages the patients disease-fighting immune system. Cases of AIDS were first identified in 1981 in the United States, but researchers have traced cases to as early as 1969. Millions of AIDS cases have been diagnosed worldwide. 2. AIDS is caused by two viruses that belong to a group called retr

24、oviruses. The first AIDS virus was isolated by researchers in France in 1983 and researchers in the United States in 1984. This virus became known as HIV-1. in 1985, scientists in France identified another closely related virus that also produces AIDS. This virus, named HIV-2, occurs mainly in Afric

25、a. HIV-1 occurs throughout the world. 3. People infected with HIV eventually develop symptoms that also may be caused by other, less serious conditions. With HIV infection, however, these symptoms are prolonged and often more severe. They include enlarged lymph glands, tiredness, fever, loss of appe

26、tite and weight, diarrhea, yeast infections of the mouth and vagina, and night sweats. 4. An HIV-infected person may develop AIDS from 2 to 15 or more years after becoming infected. In children born with HIV infection, this interval is usually shorter. A few people who have been infected with HIV fo

27、r more than 15 years have not developed any symptoms or suffer only minor symptoms. An infected person can transmit the virus to another person whether or not symptoms are present. Infection with HIV appears to be lifelong in all who become infected. 5. Researchers have identified three ways in whic

28、h HIV is transmitted: sexual intercourse, direct contact with infected blood, and transmission from an infected woman to her fetus or baby. The most common way of becoming infected is through intimate sexual contact with an HIV-infected person. In the United States, sexual transmission of HIV has oc

29、curred mainly among homosexual men, but it is becoming more frequent among heterosexual men and women. 6. People who inject drugs into their bodies can be exposed to infected blood by sharing hypodermic needles, syringes, or equipment used to prepare drugs for injection. Health-care workers can beco

30、me infected with HIV by coming into direct contact with infected blood. This may occur through injury with a needle or other sharp instrument used in treating an HIV-infected patient. A few patients have become infected while receiving treatment from an HIV-infected dentist. 7. An infected pregnant

31、woman can transmit the AIDS virus to her fetus even if she has no symptoms. Transmission may also occur from an HIV-infected mother to her baby through breast-feeding. 8. Studies indicate that HIV is not transmitted through air, food, or water, or by insects. No known cases of AIDS have resulted fro

The function of this reflex is to clear airways of inhaled irritants, debris(碎屑 ), or secretions that have

37、accumulated as a result of bacterial or viral infection. Cough may also occur in response to irritation of inflame respiratory epithelium(呼息道上皮 ), as is commonly seen with some viral infections. Irritant-initiated cough often has little effect on clearance of secretions and is called “nonproductive

38、cough“(咳痰 ). APPROACHES TO TREATMENT Cough accompanies many different disorders. Suppressing a productive cough(千咳 )can interfere with normal defense mechanisms and be potentially harmful. Suppression of nonproductive cough is safer but is not essential. Antitussive(镇咳的 ) use is justifiable in sever

39、e cases in which nonproductive cough is causing emesis, exhaustion, or significant loss of sleep. ANTITUSSIVE AGENTS Three antitussive agents are commonly used: Codeine. Codeine suppresses the cough reflex by acting directly on the medullary(延髓的 ) cough center of the brain. Its drying effect on the

40、respiratory mucosa can increase the viscosity of bronchial secretions. Antitussive effects of codeine are dose dependent in adults, but complete cough suppression may not be possible at nontoxic doses. Although codeine is the standard against which other antitussive medications are compared, it may

41、be less effective in children than in adults. The recommended dosage for children is 1mg/kg/day in four divided doses(maximum of 60 mg/day). Antitussive effects are greatest at one to two hours and persist for about four hours. Nausea, vomiting, constipation, and dizziness are the most common side e

42、ffects. In over doses, toxicity consists primarily of respiratory depression and narcosis. Limited data suggest that single doses of more than 5 mg/kg may be lethal in children. Infants may be more sensitive to codeine s effects and may have decreased ability to metabolize the drug, thus, use of cod

43、eine in children less than one year old should be discouraged. Dextromethorphan(美沙芬 ). Like codeine, dextromethorphan has antitussive activity but a very low addictive potential. In adults, the two drugs are considered equipotent. Dextromethorphans antitussive effect can begin as early as 15 to 30 m

44、inutes after a dose is taken, and its duration of action is between three and six hours. Because the drug is metabolized through oxidative pathways, infants metabolize dextromethorphan slowly and are at greater risk of dose-dependent side effects, particularly if given multiple doses. Dextromethorph

45、an and codeine both act at the same central nervous system(CNS)site. Although CNS depression can be seen with either agent, dextromethorphan has a wider margin of safety. Overdoses of up to 100 times the usual adult dose have not resulted in any fatalities. Treatment of overdose should include suppo

46、rtive measures and use of naloxone(纳洛酮 ), if respiratory depression occurs. Minor adverse effects (副作用 ) sometimes seen in nonintoxicated patients include nausea, dizziness, and slight drowsiness. Diphenhydramine(苯海拉明 ). The antihistamine diphenhydramine has weak anti tussive effects. These effects

47、may often be incomplete, however, and cough suppression may not be achived without side effects. In addition to acting on medullary cough centers, diphenhydramine has peripheral anticholinergic(抗胆碱能的 ) effects that may contribute to its cough-suppressing action. The anticholinergic effects may also

48、help to dry the respiratory tract and thicken secretions undesirable effects in patients with productive cough. In adults, 25 to 50 mg of diphenhydramine has produced cough suppression equivalent to that of 15 mg of codeine. Similar data in children are not available. GUIDELINES FOR USE OF ANTITUSSI

49、VES Remember that cough is a sign of a disorder, and it does not always require an antitussive. If it is caused by another disorder (e. g., foreign body, allergy, or asthma), therapy is more appropriately directed at the underlying cause. Do not suppress productive cough associated with chronic pulmonary diseases such as cystic fibrosis, asthma, or chronic bronchitis. Concentrate on good fluid intake, to help mobilize pulmonary secretions, and treatment of the underlying disorder. Remember that suppression of mild cou
