摘要(Abstract):

研究了萎缩性胃炎 (CAG)与海拔、气压、和季节之间的关系 ,从气象角度探讨CAG的发病机制。结果提示 :气压与CAG呈负相关 ,低气压是高原地区CAG发生的重要因素 ,气压变化是形成季节高峰的原因。低气压通过三个环节诱发CAG :一是使胃蠕动减慢 ,排空时间延长 ;二是低氧分压促使红细胞代偿性增多 ,血液粘稠度增加 ;三是低气压使胃腔气体扩张 ,对胃壁血管的压力增大。导致攻击因子增强 ,胃粘膜防御功能降低 ;胃粘膜易于受损产生炎症 ,浅表病变不易痊愈 ,最终发展成CAG。
To study the mechanism of air pressure to cause chronic atrophic gastritis (CAG). The relationship between incidence of CAG and changes of air pressure and seasons was observed for 3 years at Liupanshui City (Locates at east slope of Yun-Gui plateau,elevation 1 814 m).All the data collected were analyzed statistically. When the elevation is higher,the air pressure is lower and the incidence of CAG is higher.There is a negative correlation between air pressure and the incidence of CAG. The low atmospheric pressure is an important factor causing CAG in highland area.It slows down the peristalsis,raises blood dense.When gas expands in the stomach,it is easy for the stomach coat to be damaged and produce inflammation.This primary superficial pathological changes can not recover easily,and mostly,lead to CAG at last.
