问题 单项选择题 A2型题

某患者昨日过食生冷,脘腹冷痛,遇寒加剧,得温痛减,恶心呕吐,吐后反舒,苔白脉沉紧宜诊为()

A.寒滞胃肠证

B.胃阳虚证

C.寒湿困脾证

D.脾阳虚证

E.饮留胃肠证

答案

参考答案:A

解析:

胃阳虚证

指阳气不足,胃失温煦,以胃脘冷痛、喜温喜按,畏冷肢凉等为主要表现的虚寒证候。又名胃虚寒证。

【临床表现】胃脘冷痛,绵绵不已,时发时止,喜温喜按,食后缓解,泛吐清水或夹有不消化食物,食少脘痞,口淡不渴,倦怠乏力,畏寒肢冷,舌淡胖嫩,脉沉迟无力。

【证候分析】本证多因饮食失调,嗜食生冷,或过用苦寒、泻下之品,或脾胃素弱,阳气自衰,或久病失养,其他脏腑病变的影响,伤及胃阳所致。

胃阳不足,虚寒内生,寒凝气机,故胃脘冷痛;性属虚寒,故其痛绵绵不已,时作时止,喜温喜按,食后、按压、得温均可使病情缓解;受纳腐熟功能减退,水谷不化,胃气上逆,则食少,呕吐清水或夹不消化食物;阳虚气弱,全身失于温养,功能减退,则畏寒肢冷,体倦乏力;阳虚内寒,津液未伤,则口淡不渴;舌淡胖嫩,脉沉迟无力,为虚寒之象。

本证以胃脘冷痛、喜温喜按,畏冷肢凉为辨证的主要依据。

Few creatures on earth are as cute as the black lion tamarin, and few have as dramatic a story line. Pug-nosed and diminutive, with a comic fringe of hair, these monkeys dwell in trees in small tracts of forest in southeastern Brazil. Or they did until 1905, when they were declared extinct. No one saw a black lion tamarin again in the wild until 1970. Later, in the 1990s, some Brazilian researchers turned up a small set of isolated, inbred populations scattered over a wide region. Since that time, they have been engineering tamarin migration, doing everything they can to save the world’s most distinctive primates.
Although they are no larger than house cats, tamarins have brains big for their size and a family life organized like our own. They live in groups anchored by an adult male andadult female, along with their offspring. When a mother bears young, she usually produces twins, and although members of the group share in their upbringing, it is most often the father who carries them around in the trees, where the families feed on fruits, insects and bird’s eggs.
Unhappily for the lion tamarins, their tree-bound niche began to disappear after the Portuguese landed in Brazil and began clearing forest to make room for Rio de Janeiro, the settlements and farms. As is the case for so many threatened species, the breakup of their habitat sounded the death knell for tamarins, depriving them of the continuity of forest they require to remain abundant and safe from potential threats in any single vicinity. The animals avoid predators by hardly ever coming down from the trees, so even a narrow logging road through a forest can begin the breakup by preventing them from moving from one patch of forest to another.
A simple solution was to build bridges across roads, allowing the monkeys to move from one forest to another. With some lumber and the researchers’ work, habitats that had been separated became continuous again, improving opportunities for migrating and mating.
The next step was to broaden the distribution of the population. The researchers captured two families of black lion tamarins and moved them to a new forest. After a year, the moves were declared a success: Not only had 80 percent of the tamarins survived, but they had also produced new offspring. So far, so good. The researchers had learned the animals could adjust to the new habitats, even if the insects there tasted a little different or the trees were a slightly different size.
The techniques for saving species in the wild vary. Species with less stringent habitat requirements, like wild turkeys, have been rescued by moving them into new settings as well as outlawing their killing. More challenging to preserve are species that require a lot of land, like elephants, and species that have highly specific requirements for habitat and prey -- like black-footed ferrets. Ultimately, as in all challenges, knowledge is power to save wild species from extinction.

To save the wild species from extinction, the author put the stress on ______.

A.knowledge

B.technique

C.persistence

D.confidence
