幽门螺杆菌感染胃炎患儿胃黏膜ASICs表达在胃肠道动力中的作用

幽门螺杆菌感染胃炎患儿胃黏膜ASICs表达在胃肠道动力中的作用摘要：

随着幽门螺杆菌的感染率逐渐上升，幽门螺杆菌感染胃炎已成为常见的胃病之一。本文通过对幽门螺杆菌感染胃炎患儿及健康儿童胃黏膜ASICs表达情况的对比分析，探讨了ASICs在胃肠道动力中的作用，发现幽门螺杆菌感染胃炎患儿胃黏膜ASICs表达水平显著低于健康儿童，同时幽门螺杆菌感染胃炎患儿肠道动力学指标明显受损。进一步研究发现，ASICs通过参与胃酸分泌、胃肠道平滑肌收缩、肠道黏液分泌等多个方面对胃肠道运动起到重要的调节作用。因此，维护正常ASICs表达水平有助于防止幽门螺杆菌感染胃炎和相关胃肠道功能障碍的发生。

Abstract:

WiththegradualincreaseintheinfectionrateofHelicobacterpylori,H.pylori-infectedgastritishasbecomeoneofthecommonstomachdiseases.Inthispaper,theexpressionofASICsingastricmucosaofH.pylori-infectedchildrenwithgastritisandhealthychildrenwascomparedandanalyzedtoexploretheroleofASICsingastrointestinalmotility.ItwasfoundthattheexpressionlevelofgastricmucosalASICsinH.pylori-infectedchildrenwithgastritiswassignificantlylowerthanthatinhealthychildren,andthegastrointestinalmotilityindexofH.pylori-infectedchildrenwithgastritiswassignificantlyimpaired.FurtherstudieshaveshownthatASICsplayanimportantregulatoryroleingastrointestinalmotilitybyparticipatingingastricacidsecretion,smoothmusclecontractionofthegastrointestinaltract,intestinalmucussecretion,andotheraspects.Therefore,maintaininganormallevelofASICsexpressioncanhelppreventtheoccurrenceofH.pyloriinfectionandrelatedgastrointestinalfunctionaldisorders.
