 Directions:

  Read the following text carefully and then translate the underlined segments into Chinese. Your translation should be written neatly on the ANSWER SHEET. (10 points)

  It was only after I started to write a weekly column about the medical journals, and began to read scientific papers from beginning to end, that I realised just how bad much of the medical literature frequently was. I came to recognise various signs of a bad paper: the kind of paper that purports to show that people who eat more than one kilo of broccoli a week were 1.17 times more likely than those who eat less to suffer late in life from pernicious anaemia. (46) There is a great deal of this kind of nonsense in the medical journals which, when taken up by broadcasters and the lay press, generates both health scares and short-lived dietary enthusiasms.

  Why is so much bad science published? A recent paper, titled “The Natural Selection of Bad Science”, published on the Royal Society’s open science website, attempts to answer this intriguing and important question. It says that the problem is not merely that people do bad science, but that our current system of career advancement positively encourages it. What is important is not truth, but publication, which has become almost an end in itself. There has been a kind of inflationary process at work: (47) nowadays anyone applying for a research post has to have published twice the number of papers that would have been required for the same post only 10 years ago. Never mind the quality, then, count the number.

  (48) Attempts have been made to curb this tendency, for example, by trying to incorporate some measure of quality as well as quantity into the assessment of an applicant’s papers. This is the famed citation index, that is to say the number of times a paper has been quoted elsewhere in the scientific literature, the assumption being that an important paper will be cited more often than one of small account. (49) This would be reasonable if it were not for the fact that scientists can easily arrange to cite themselves in their future publications, or get associates to do so for them in return for similar favours.

  Boiling down an individual’s output to simple metrics, such as number of publications or journal impacts, entails considerable savings in time, energy and ambiguity. Unfortunately, the long-term costs of using simple quantitative metrics to assess researcher merit are likely to be quite great. (50) If we are serious about ensuring that our science is both meaningful and reproducible, we must ensure that our institutions encourage that kind of science.

下列哪项符合原发性高血压高度危险组标准?

A.高血压2级伴1个危险因素者
B.高血压2级伴2个危险因素者
C.高血压2级伴靶器官损害
D.高血压1~2级伴3个危险因素者
答案:D
解析:

脾切除可获得明显疗效的疾病是
A.遗传性球形红细胞增多症 B.遗传性椭圆形红细胞增多症
C.丙酮酸激酶缺乏 D.珠蛋白生成障碍性贫血

答案:A
解析:
①遗传性球形红细胞增多症患者,由于其球形红细胞胞 膜的内在缺陷,导致其过早衰老,易在脾内滞留、破坏。临床表现为贫血、黄疸和脾肿大。脾切除可获得 明显疗效,术后黄疸和贫血多在短期内消失,贫血可获完全、持久纠正,是脾切除治疗效果最好的造血系 统疾病。但术后血液中球形细胞仍然存在。②遗传性椭圆形红细胞增多症为少见疾病,血液中出现大 量以椭圆形细胞为主的异形红细胞,有溶血性贫血和黄疸者,脾切除对消除贫血和黄疸有效,但术后血 液中椭圆形红细胞仍然增多。③丙酮酸激酶缺乏的患者,由于红细胞内缺乏丙酮酸激酶,其生存期缩 短,在脾中破坏增多。此病新生儿期即出现症状,黄疸和贫血都较重。脾切除虽不能纠正贫血,但有助 于减少输血量。④珠蛋白生成障碍性贫血患者可有黄疸、肝脾肿大,脾切除主要是减少红细胞在脾中的 破坏,对减轻溶血、减少输血量有帮助。参阅7版外科学P589、P590。
