摘  要:为探讨胃粘膜幽门螺杆菌(Hp)感染与胃癌发生的关系,采用快速尿素酶法及免疫组织化学方法,检测100例胃粘膜活检组织中Hp感染、增生细胞核抗原(PCNA)和细胞凋亡的状况。结果显示:慢性浅表性胃炎、慢性萎缩性胃炎、异型增生和腺癌,Hp感染率逐渐升高。定量分析发现,随病变加重,单位面积内PCNA免疫阳性细胞数逐渐升高,而细胞凋亡变化不明显。在同一类型病变中,Hp感染者细胞增生指标PCNA明显高于Hp阴性者,而凋亡指数却低于Hp阴性者。提示Hp感染在胃癌变过程中有重要的生物学意义。The objective of this study was to investigate the correlation between Helicobacter pylori(Hp)infection and gastric carcinogenesis.Rapid urease and immunohistochemical methods were adopted to detect Hpinfection and expression of proliferating cell nuclear antigen(PCNA)and apoptosis in gastric mucosa with various lesions.Results showed that Hppositivity increased in degree with chronic superficial gastritis,chronic atrophic gastritis,dysplasia and adenocarcinoma.The number of PCNA immunostaining positive cells/mm2 increased with progression of lesions,but apoptosis varied slightly.However,in a similar lesions,Hppositive lesions had higher PCNA and lower apoptotic index than Hpnegative.The findings indicated that Hpinfection may have an important biological significance in gastric carcinogenesis.
