A.减轻肾小球炎症反应

B.预防记性肾功能衰竭

D.彻底清楚感染灶

E.对症处理

答案

参考答案:D

解析:

急性肾小球肾炎是由一组不同病因所致的感染后免疫反应引起的急性弥漫性肾小球病变,是在细菌感染后,刺激机体产生抗体,最终形成抗原抗体复合物,沉积于肾小球并引起补体激活,最终损伤肾小球。本病属于自限性疾病。使用抗生素主要为彻底清楚感染灶,减少抗原抗体符合物的形成、缩短病程。

单项选择题

Modern industrial society grants little status to old people. In fact, such a society has a system of built-in obsolescence. There is no formal system for continuing our education throughout our life in order to keep up with rapidly changing knowledge. When our education and job skills have grown obsolete, we are treated exactly like those who have never gained an education or job skills and are not encouraged or given the opportunity to begin anew.
As a society becomes more highly developed, the overall status of older people diminishes. Improved health technology creates a large pool of old people, who compete for jobs with the young. However, economic technology lowers the demand for workers and creates new jobs for which the skills of the aged are obsolete, forcing older people into retirement. At the same time, young people are being educated in the new technology and are keeping pace with rapid changes in knowledge. Finally, urbanization creates age-segregated neighborhoods. Because the old live on fixed incomes, they must often live in inferior housing. All these factors—retirement, obsolete knowledge and skills, inferior standards of living—lower the status of the aged in society.
A century ago, when one could expect to live only to 50 or so, the life span more or less coincided with the occupation and family cycle. But today the average life span allows for fifteen to twenty years of life after these cycles. It appears that our life span is outpacing our usefulness in society.

Which of the following would be the best title for this passage

A.The Problem of Aging

B.Social Structures

C.Economic Technology

D.Continuing Education
