题型:单项选择题

题目:

女性,38岁,反复发作右上腹疼痛3年。 1天前进食油腻食物后腹痛,继之高热 39.2℃,疼痛向右肩背部放射,无黄疽,来院急诊。体格检齐:右上腹压痛、反跳痛。

诊断明确,宜采取何种手术方式

A.胆总管切开引流

B.胆囊切除术

C.胆囊造口术

D.腹腔镜胆囊切除术

E.胆肠内引流术

答案:

参考答案:B

解析:诊断明确,应采取开腹胆囊切除术。对于慢性胆囊炎或胆囊炎症状轻者也可选择腹腔镜胆囊切除术。胆囊造口水适合高龄危重病人,或遇局部解剖不清、粘连严重者。胆总管切开引流用于胆总管内有结石,胆总管扩张者。胆肠内引流术适合胆总管下端梗阻、胆总管明显扩张者。

题型:单项选择题

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.

Which of the following is NOT characteristic of a tamarin family

A.A tamarin family consists of Father, Mother and their children.

B.The family life is organized like humans.

C.All the family members share the responsibility in the upbringing.

D.Tamarin brains are big for their size.
