问题 单项选择题 B1型题

高位单纯性直瘘宜采用()

A.肛瘘切开术

B.肛瘘挂线疗法

C.肛瘘外口扩大术

D.药物保留灌肠治疗

E.肛瘘部分切开十肛瘘挂线术

答案

参考答案:B

解析:瘘管切开术是将瘘管全部切开开放,靠肉芽组织生长使伤口愈合的方法。适用于低位肛瘘,因瘘管在外括约肌深部以下。切开后只损伤外括约肌皮下部和浅部,不会出现术后肛门失禁。故题1选A。挂线疗法是利用橡皮筋或有腐蚀作用的药线的机械性压迫作用,缓慢切开肛瘘的方法。适用于距肛门3~5cm内,有内外口低位或高位单纯性肛瘘,它的最大优点是不会造成肛门失禁。故题2选B。蹄铁形肛瘘的治疗宜采用肛瘘部分切开十肛瘘挂线术。故题3选E。

Americans think that travel is good for you, some even think it can help one of the country's worst problems-crime (犯罪).    

Crime worries a lot of people. Every year, the number of crimes goes up and up. And many criminals (罪犯)are young. They often come from sad homes, with only one parent or no parents at all.

There are many young criminals in prison. But prison doesn't change them. Six or seven in ten will go back to crime when they come out of prison.

One man, Bob Burton, thought of a new idea. In the old days, young men had to live a difficult life on the road. They learned to be strong and brave, and to help theft friends ill time of danger. This helped them to grow into men. So Bob Burton started" Vision Quest".

He takes young criminals on a long, long journey with horses and wagons(马车), 3,000 miles through seven states. They are on the road for more than a year.

The young people on Vision Quest all have bad problems. Most of them have already spent time in prison. This is their last chance.    

It's hard work on the road. The work starts before the sun comes up. The boys and girls have to feed the horses. Some of them have never loved anyone before. But they can love their horse. That love can help them to a new life.

 Not all the young people on Vision Quest will leave crime behind them. Three or four in ten will one day_____________. Bob Burton is right. Travel can be good for you. Even today. Americans still say, " Go west, young man."
