摘　　要：目的:研究幽门螺杆菌L型感染对胃癌组织中增殖、凋亡、侵袭分子表达的影响。方法:收集在我院手术切除的胃癌组织,根据幽门螺杆菌感染情况分为Hp阴性、Hp-L阴性、Hp-L阳性。检测增殖、凋亡、侵袭基因的表达量。结果:Hp-L阳性胃癌组织中LOXL2、PCNA、CyclinD1、Rab1A、Bcl-2、Snail、N-cadherin、UHRF1、AnnexinII的mRNA表达量显著高于Hp-L阴性、Hp阴性胃癌组织,ING5、PTPN13、Beclin1、Mst1的mRNA表达量显著低于Hp-L阴性、Hp阴性胃癌组织;Hp-L阴性胃癌组织中LOXL2、PCNA、CyclinD1、Rab1A、Bcl-2、ING5、PTPN13、Beclin1、Mst1、Snail、N-cadherin、UHRF1、AnnexinII的mRNA表达量与Hp阴性胃癌组织比较无差异。结论:幽门螺杆菌L型感染能够通过影响增殖、凋亡、侵袭基因的表达来促进细胞增殖及侵袭、抑制细胞凋亡。Objective： To study the effect of helicobacter pylori L-form infection on proliferation, apoptosis and invasion molecule expression in gastric cancer tissue.Methods： The gastric cancer tissues surgically removed in our hospital between May 2013 and October 2016 were collected and divided into Hp negative, Hp-L negative and Hp-L positive according to the condition of helicobacter pylori infection.The proliferation, apoptosis and invasion gene expression were detected.Results： LOXL2, PCNA, CyclinD1, Rab1A, Bcl-2, Snail, N-cadherin, UHRF1 and AnnexinII mRNA expression in Hp-L-positive gastric cancer tissues were significantly higher than those in Hp-L-negative and Hp-negative gastric cancer tissues while ING5, PTPN13, Beclin1 and Mst1 mRNA expression were significantly lower than those in Hp-L-negative and Hp-negative gastric cancer tissues;LOXL2, PCNA, CyclinD1, Rab1A, Bcl-2, ING5, PTPN13, Beclin1, Mst1, Snail, N-cadherin, UHRF1 and AnnexinII mRNA expression in Hp-L-negative gastric cancer tissues were not different from those in Hp-negative gastric cancer tissues.Conclusions： Helicobacter pylori L-form infection can influence the proliferation, apoptosis and invasion gene expression to promote cell proliferation and invasion, and inhibit cell apoptosis.
