普查宫颈癌时最有实用价值的检查方法是()

A.子宫颈刮片细胞学检查

B.宫颈碘试验

C.氮激光肿瘤固有荧光诊断法

D. * * 镜检查

E.染色体检查

答案

参考答案:C

解析:

这是一道理解记忆题,考核学生对宫颈癌辅助检查的认识。常见错误为选择A或B或D。选项A,子宫颈刮片细胞学检查是最常用的宫颈癌普查方法,因而误选;选项B,碘试验简单,可用于识别宫颈病变的危险区,以便确定活检取材部位,提高诊断率,故认为最有实用价值;选项D.因 * * 镜检查可观察宫颈表面有无异型上皮或早期癌变,并选择病变部位进行活组织检查,以提高诊断正确率。以上错误的原因在于对宫颈癌的各种辅助检查缺乏正确的认识。正确答案为C。

氮激光肿瘤固有荧光诊断法根据荧光素与肿瘤亲和作用,利用人体内原有荧光(即固有荧光),通过光导纤维传送激光(常用氮激光)激发病变部位,目测病灶组织与正常组织发出的不同颜色加以诊断:见宫颈表面呈紫色或紫红色为阳性,提示有病变;出现蓝白色为阴性,提示无恶性病变。该法比传统的子宫颈刮片细胞学检查方法简便,立即出结果,对于普查宫颈癌最有实用价值的。宫颈碘试验、 * * 镜检查选择病变部位进行活组织检查,可以提高诊断正确率,但不适合于普查。

A

One night recently, I was driving down a two-lane highway at about 60 miles an hour. A car approached from the opposite direction at about the same speed. As we passed each other, I caught the other driver’s eye for only a second. I wondered whether he might be thinking, as I was, how dependent we were on each other at that moment. I was relying on him not to fall asleep, not to be put off by a phone conversation, not to cross over into my lane and bring my life to a sudden end. Though we had never spoken a word to each other, he relied on me in just the same way.

Multiplied a million times over, I believe that is the way the world works. At some level, we all depend upon one another. Sometimes that dependence requires us simply not to do something like crossing over the double yellow line. And sometimes it requires us to act cooperatively, with friends or even with strangers.

As technology shrinks our world, the need increases for cooperative action among nations. In 2003, doctors in five nations were quickly organized to identify the SARS virus, which saved thousands of lives. The threat of international terrorism has shown itself to be a similar problem, one requiring team action by police and intelligence forces across the world. We must recognize that our fates are not ours alone to control.

In my own life, I’ve put great stock in personal responsibility. But, as time has passed, I’ve also come to believe that there are moments when one must rely upon the good faith and judgment of others. so, while each of us faces the case of driving alone down a dark road, what we must learn is that the approaching light may not be a threat, but a shared moment of trust.
