问题 单项选择题 A1/A2型题

一般新生儿用药量宜少,间隔时间应适当延长的药是()

A.戊巴比妥

B.新生霉素

C.吲哚美辛

D.喹诺酮类药物

E.氨茶碱

答案

参考答案:C

解析:胆红素代谢过程中肝细胞膜上特异性受体能摄取未结合的胆红素,并由载体蛋白将其转运至内质网,在葡萄糖转移酶的催化下与葡萄糖醛酸结合成结合型胆红素。新生霉素具有抑制葡萄糖醛酸转移酶的作用,使血液中的游离胆红素浓度增高,引起高胆红素血症;吲哚美辛具有一定的肾毒性,而新生儿肾血流、肾滤过率、肾小球排泄率都低于年长儿和成年人,使血液中药物蓄积,血药浓度升高,引起肾脏损害。

Both the young and the old may feel lonely. A three-year-old child will feel lonely when it is left alone, and an old man over eighty years old is often afraid to live alone, too.

Some people feel lonely because they may not have enough time to make friends. Not only the quiet, shy people may feel lonely. Some people are active and outgoing, but they are sometimes afraid to talk and make friends with others. They always try to hold other people away from them. They may seem to have lots of friends, but inside they are hurting.

Are you lonely? If your answer is “yes”, you may need to work hard enough! Here are some tips to think about:

To be wanted and needed is a big answer to loneliness. Is there any way you can help other people? Try to do something helpful for others even if you are very busy. By helping other people, we find friends and lose loneliness.

Do you have an interest or hobby? Find a group of people with this interest and join them.

Live in the real world! The world on the Internet is not a real world and it is very different from the real life. The students asleep in class are mostly those who often surf the net through the night. As a result, they’ll get lost in the real world.

Don’t wait for someone to phone, or write, or email you, you call them. And if they seem too busy, it doesn’t mean you are not welcome. Try another time!

When you’ve done anything wrong to other people, don’t be too proud to say sorry. You must do that even if you find it hard to open your mouth.
