试题解析

复合性溃疡

胃溃疡和十二指肠溃疡同时存在是复合性溃疡。这种溃疡占溃疡病患者的5%左右。先患十二指肠溃疡的患者居多,从而导致功能性幽门梗阻,可引起排空延缓,胃扩张而刺激胃泌素分泌,使胃酸分泌增多而幽门功能不良致十二指肠液返流入胃,反复刺激胃而形成胃溃疡。复合性溃疡的患者,胃溃疡的发生先于十二指肠溃疡的也有但比例很小,复合性溃疡男性多于女性。此病出血的发生率较高,但恶变率较低。

临床诊断

临床诊断是指医生给病人检查疾病. 并对病人疾病的病因、发病机制作出分类鉴别,以此作为制定治疗方案的方法和途径。诊断的首要步骤就是通过询问就诊者的主观感受症状来采集病史资料。病史对诊断可起到定向作用,能提示诊断的线索。

男性

男性即男人。指雄性人类,与雌性人类(女性)成对比。男性这个名词是用来表示生物学上的性别划分或文化上的性别角色,或二者皆有。男人通常是指一个从男孩过渡到下一个时期的男性,与女人成对比。不过男人有时候也可以用来指称所有的男性。当男孩长大成熟后,他们就成为所谓的男人。不过有时在口语上也会用来指称青少年男性。2022年1月17日,国家统计局发布2021年中国经济数据。年末全国人口(包括31个省、自治区、直辖市和现役军人的人口,不包括居住在31个省、自治区、直辖市的港澳台居民和外籍人员)141260万人,比上年末增加48万人。从性别构成看,男性人口72311万人,总人口性别比为104.88(以女性为100)。

临床上最常见呕血原因为()

Passage 2Everyone knows that English departments are in trouble, but you can't appreciate just how much trouble until you read the new report from the Modern Language Association. The report is about Ph.D. programs, which have been in decline since 2008. These programs have gotten both more difficult and less rewarding: today, it can take almost a decade to get a doctorate, and, at the end of your program, you' re unlikely to find a tenure-track job.The core of the problem is, of course, the job market. The M.L.A. report estimates that only sixty per cent of newly-minted Ph.D.s will find tenure-track jobs after graduation. If anything, that's wildly optimistic: the M.L.A. got to that figure by comparing the number of tenure-track jobs on its job list(around six hundred) with the number of new graduates(about a thousand). But that leaves out the thousands of unemployed graduates from past years who are still job-hunting-not to mention the older professors who didn't receive tenure, and who now find themselves competing with their former students. In all likelihood, the number of jobs per candidate is much smaller than the report suggests. That's why the mood is so dire-why even professors are starting to ask, in the committee's words, "Why maintain doctoral study in the modern languages and literatures-or the rest of the humanities-at all?"Those trends, in turn, are part of an even larger story having to do with the expansion and transformation of American education after the Second World War. Essentially, colleges grew less elite and more vocational. Before the war, relatively few people went to college. Then, in the nineteen-fifties, the G.I. Bill and, later, the Baby Boom pushed colleges to grow rapidly. When the boom ended, colleges found themselves overextended and competing for students. By the mid-seventies, schools were creating new programs designed to attract a broader range of students-for instance, women and minorities.Those reforms worked: as Nate Silver reported in the Times last summer, about twice as many people attend college per capita now as did forty years ago. But all that expansion changed colleges.In the past, they had catered to elite students who were happy to major in the traditional liberal arts. Now, to attract middle-class students, colleges had to offer more career-focused majors, in fields like business, communications, and health care. As a result, humanities departments have found themselves drifting away from the center of the university. Today, they are often regarded as a kind of institutional luxury, paid for by dynamic, cheap, and growing programs in, say, adult-education. These large demographic facts are contributing to today's job-market crisis: they' re why, while education as a whole is growing, the humanities aren't.Given all this, what can an English department do? The M.L.A. report contains a number of suggestions. Pride of place is given to the idea that grad school should be shorter: "Departments should design programs that can be completed in five years."That will probably require changing the dissertation from a draft of an academic book into something shorter and simpler. At the same time, graduate students are encouraged to "broaden" themselves: to "engage more deeply with technology"; to pursue unusual and imaginative dissertation projects; to work in more than one discipline; to acquire teaching skills aimed at online and community-college students; and to take workshops on subjects, such as project management and grant writing, which might be of value outside of academia. Graduate programs, the committee suggests, should accept the fact that many of their students will have non-tenured, or even non-academic, careers. They should keep track of what happens to their graduates, so that students who decide to leave academia have a non-academic alumni network to draw upon.According to the author, which of the following is the key reason that leads to today's job-market crisis for Ph.D. students?
