提示重症胰腺炎的体征是:()。

A.Courvoisier征阳性

B.肝浊音界消失

C.Grey-Tumer征阳性

D.Murphy征阳性

E.肝区叩击痛阳性

答案

参考答案:C

解析:皮肤瘀斑。多见于重症急性胰腺炎,这是由于重症急性胰腺炎时大量的血液进入腹腔,并沿筋膜面到达腹壁所致。可在腰部皮肤出现蓝-绿-棕色皮肤斑,称之为Grey-Tumer征,为血液通过腹膜后途径渗入腹壁所致。另外在脐周的皮肤也可出现蓝色皮肤斑,称之为Cullen征,这是由于血液渗入腹壁肌肉所引起。Courvoisier征是指在胰头癌压迫胆总管导致阻塞时,发生明显黄疸,且逐渐加深,胆囊显著肿大,但无压痛。Murphy征是急性胆囊炎的典型体征。

For many writers, writing stories or plays is a part-time job: to support themselves they take on other jobs, such as teaching. It is one sign of August Wilson’s success that for many years he has been able to make a living only by writing plays.

Wilson was born in Pittsburgh and dropped out of school in the ninth grade. He was a good reader, however, and continued his education by reading library books, learning about black nationalist movements of the time, and closely observing(观察) the lives of the poor people.

In the late 1960’s Wilson set up a theater company called Black Horizons and began to think of ways to describe African-American life on the stage. He had the idea of a cycle of plays, each of which was set in a different decade(十年) of the 20th century, showing how African-American life has developed.

The first successful play of this series was Ma Rainey’s Black Bottom about black musicians in Chicago in the 1920s, who are not accepted by white society. Other plays in the series include Joe Turner’s Come and Gone, about blacks in the 1910s who had moved north to Pittsburgh in search of a new identity; Fences, which focuses on a father–son conflict(冲突) in the1950s; and The Piano Lesson, about a 1930s family that was uncertain about whether to sell the family’s treasure. For the last two of these plays Wilson was awarded Pulitzer Prizes.

Wilson has written eight plays in his cycle, the most recent being King Hedley the Second, a play set in the 1980s. His plays are enjoyed by both the blacks and the whites and engage anyone who is interested in African-American experience.
