细菌性痢疾的肠溃疡特征为

A.溃疡呈环形与肠的长轴垂直
B.溃疡呈长椭圆形与肠的长轴平行
C.溃疡呈烧瓶状口小底大
D.溃疡边缘呈堤状隆起
E.溃疡表浅呈地图状

答案

参考答案:E

解析:肠伤寒以回肠下段的集合淋巴结和孤立淋巴结的病变最为显著。其溃疡外形与受侵淋巴组织相似,回肠下段多为集合淋巴结,此淋巴结呈长椭圆形,其长轴与肠管的长轴一致。溃疡如侵蚀血管则致肠出血。溃疡如向深部侵蚀,穿透肌层及浆膜则致肠空孔。细菌性痢疾的溃疡形状、大小不一,比较浅表,呈地图状,一般仅限于粘膜层,极少有穿过粘膜层到达肌层而引起肠穿孔的并发症。溃疡之间的肠粘膜表现为充血、水肿、炎细胞浸润等改变。溃疡呈环形与肠的长轴垂直是肠结核的病变特征。溃疡呈烧瓶状、口小底大是肠阿米巴病的病变特征。溃疡边缘呈堤状隆起是溃疡型肠癌的病变特征。

Last year more than 13 Korean (韩国) TV series were introduced in China. Turn on the TV, and Korean beauties are appearing during peak viewing times(黄金时段). Some of the dramas are being repeated, but audiences continue to watch them. Why are the South Korean TV series loved by so many Chinese people? Cheng Yiting, a student from East China Normal University, gives us her reasons.
