幽門螺桿菌感染胃炎患兒胃黏膜ASICs表達(dá)在胃腸道動(dòng)力中的作用

幽門螺桿菌感染胃炎患兒胃黏膜ASICs表達(dá)在胃腸道動(dòng)力中的作用摘要：

隨著幽門螺桿菌的感染率逐漸上升，幽門螺桿菌感染胃炎已成為常見的胃病之一。本文通過對(duì)幽門螺桿菌感染胃炎患兒及健康兒童胃黏膜ASICs表達(dá)情況的對(duì)比分析，探討了ASICs在胃腸道動(dòng)力中的作用，發(fā)現(xiàn)幽門螺桿菌感染胃炎患兒胃黏膜ASICs表達(dá)水平顯著低于健康兒童，同時(shí)幽門螺桿菌感染胃炎患兒腸道動(dòng)力學(xué)指標(biāo)明顯受損。進(jìn)一步研究發(fā)現(xiàn)，ASICs通過參與胃酸分泌、胃腸道平滑肌收縮、腸道黏液分泌等多個(gè)方面對(duì)胃腸道運(yùn)動(dòng)起到重要的調(diào)節(jié)作用。因此，維護(hù)正常ASICs表達(dá)水平有助于防止幽門螺桿菌感染胃炎和相關(guān)胃腸道功能障礙的發(fā)生。

Abstract:

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