关于淀粉酶与急性胰腺炎的关系,下列错误的是 ()

A.重症胰腺炎的淀粉酶值可正常或低于正常

B.部分急腹症的淀粉酶一般不超过正常值的2倍

C.血淀粉酶的高低反映病情轻重

D.尿淀粉酶值受患者尿量的影响

E.胰源性胸腔积液和腹水中的淀粉酶值亦明显升高

答案

参考答案:C

解析:血清淀粉酶的高低不一定反映病情轻重,出血坏死型胰腺炎淀粉酶值可正常或低于正常。尿淀粉酶升高较晚,受患者尿量的影响。胰源性腹水和胸腔积液中的淀粉酶值亦明显升高。

Donald had his own difficulties in sleeping that night. Not just because of the bright lights of the shelter or people’s constant voices, it was the happening repeatedly nightmare that caused him to stay awake, to fear sleep. Donald was back in his small house. He did his best to ignore the howling winds outside his window. Yet he could not turn out the fearful whimpers (呜咽) of his little dog, or the uncomfortable sounds of his mother anxious in her room next door, unable to sleep through the storm despite her insistence they would be all right.

Donald did not want his mother to be upset, but on some level, he was glad to hear she was awake, It meant he was not alone in the dark. Though he was 12, until recently it was impossible for Donald to fall asleep unless his mother lay down by his side.

Suddenly there was a crash. Their living room window is shattered (打碎) by 125 miles an hour winds. Troy rushed to Donald and sat anxiously on the edge of his bed. He did his best to calm his mother, and she had to comfort him. Soon water was seeping (渗入) into the single floor house. Quickly it rose from ankle level to leg level. At Donald’s insistence, they pushed their way through the water --- now chest high --- toward the front door. When they fought their way into the living room, water rose to their chins.

It was a struggle for the boy and mother to stay afloat. In a total panic, desperate to hold on to something, Troy caught a curtain rod. She was breathing hard, shouting that she couldn’t swim.

Donald cried out, “Mom! Hold on!” Just then Donald also caught a floatable wood board.
