问题 单项选择题 A1/A2型题

肝功能不全时常见的并发症是()

A.肺梗死

B.脑病

C.心肌梗死

D.红细胞增多症

E.脾破裂

答案

参考答案:B

解析:肝功能不全患者,尤其是肝硬化患者,最常见的并发症是门脉高压、腹水和肝性脑病。由于肝实质细胞破坏导致肝动脉和门静脉短路形成,以及纤维组织压迫,可以引起门脉高压,伴随门脉高压和低蛋白血症、水钠潴留,极易形成腹水。肝性脑病的发生则主要由于氨中毒、假性神经递质作用及脑内能量代谢障碍所致。

Many of us already know about several American superstitions(迷信). Having a black cat cross your path, walking under a ladder, and breaking a mirror are all bad luck. In addition, there are many other superstitions that are worth knowing. Understanding them will keep you safe from evil spirits —if you believe in such things —and impress your American friends when you mention them.

Like the superstitions in other cultures, American superstitions often involve the things important in daily life, such as health, numbers, and marriage. For example, have you ever had a cough that would not go away? According to one American superstition, you should take a piece of your hair and put it between two slices of buttered bread. Next, feed this hair sandwich to a dog and say, “Eat well, you hound, may you be sick and I be sound.” This will trick the evil spirits and help your cough. It will also raise some eyebrows if you try it.

In American superstitions, the number three is very important. Often, Americas will say, “All things come in threes.” Three is lucky because it represents the traditional family: mother, father, and child. Therefore, gifts, letters, and guests will often arrive at your home in groups of three. However, it is also possible for bad events, like accidents and funerals, to come in threes as well.

Another time people pay attention to superstitions is when they get married. During a wedding, brides must wear or carry “something old, something new, something borrowed, and something blue”. The old and borrowed things will bring luck to the person who gives them to the bride. The new and blue things will bring good fortune to the bride herself. The next time someone you know is getting married, be sure to recite this phrase.

As it would be unlucky to discuss one more superstition, we will wind things up here. Keep your fingers crossed, and stay lucky!
