不同海拔的胃癌高发地区幽门弯曲菌感染的对比性分析

COMPAIATIVE STUDY ON LNFECTION WITH PYLORIC WINDING BACTERIA AT DIFFEIENT INCIDENCE REGIONS OF STOMACH CANCE

胃粘膜活检576例,其中276例来自南京地区(A组),300例来自西宁地区(B组)。用硷性复红法染色观察幽门弯曲菌(CP)。结果CP检出率在两组有极明显差异:A组69.9％,B组21.0％,这提示CP感染可能与两地区海拔、气候、地理生活坏境、饮食结构习惯等不同有关。两组中活动性慢性胃炎CP检出率均显著高于各组总检出率,提示CP可能是活动性慢性胃炎发生的常见原因。两组同为胃癌高发地区,CP检出率却有明显不同,也说明CP与胃癌的发生是否有关是值得进一步探讨的问题。

There are 576 cases of gastritis membrane biopsy, of which 278 came from Nanjing region(Group A)300 from Xining region(G roup B). we observed cp through alkalinestain. As a result, the rate of tests of the cp in two groups were quite different. Group A was 69％, Group B Was 21.0％. This indicated that Cp infection might relate to the difference of elevatiOn,climate,geographical and living environment,the diet structure and diet habit, erc, Both Cp rate of teet of active chronic gastritis in two groups were obviosly high er than the total tests of each group. This indicated that Cp may be the common cause of active chronic gastritis. These two groups region were exactly high incidenceregion (the place where stomach cancer usually Occured,)but Cp tests were remarkably different. This also proved that the question whether Cp related to the Occurence of the cancer of stomach would be worthy being done futher.
