问题 单项选择题

有关患者出现低血糖叙述不正确的是()

A.患者出现精神症状是由于血糖过低对神经系统的影响

B.进一步发展可能出现意识障碍

C.意识障碍的水平与血糖浓度正相关,因此血糖可以作为昏迷程度的标准

D.可出现醉酒状态

E.脑功能受损从皮层逐渐向下累及皮层下组织

答案

参考答案:C

解析:低血糖对脑的影响以发育最晚,功能最高的部位最易、最先受累,从大脑皮层逐渐向下累及皮下组织,包括基底节、下丘脑及自主神经中枢,最后影响中脑和延髓。故低血糖时会产生多种神经精神症状。出现意识障碍、醉酒状态、情感不稳、幻觉等。血糖并不能完全反映脑内的糖含量,困此血糖不可以作为昏迷程度的标准。

Recently, my class went on a three-day trip from Shanghai to Nanjing with only 200 yuan. It was fun and inspiring. We left for Nanjing early in the morning (4:52 a.m. on March 19) by train. Unfortunately, because the tickets were difficult to get, we took the train without seats. The carriage quickly became crowded with students. We stood on the train for over five hours until we arrived at our destination —Nanjing. By that time we all understood how hard it is for migrant workers to return home from a big city.

We had an educational campaign in front of the Memorial Hall to the Victims of the Nanjing Massacre by Japanese Invaders on the first day. We all felt the heavy weight of history as we walked quietly around the Memorial Hall. Relics of the war on display frightened and shocked us. We could imagine how hard life must have been for the Chinese people at that time.

On the second day we were divided into groups of seven to nine students. We were assigned to do research about the city, so we had to visit local people and talk with them. As we were told not to take taxis, we traveled around the city by bus or subway. At the end of the day, we were so tired that no one touched the remote control of the television in our bedroom. However, we were all happy that we had learned to get around a strange city and that we understood Nanjing more.

On the last day we went to Yuhuatai. Some students handed in applications to join the Communist Party there. We learnt about the martyrs(烈士) stories and most of us were impressed by their noble spirits. They sacrificed their lives but they won great respect.

Our three days soon came to an end. Sitting on the train back to Shanhai, we happily shared our adventures in Nanjing. Though we were tired, it was a really meaningful trip.
