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 Hpinfection and expression of proliferating cell nuclear antigen(PCNA)and apoptosis in gastric mucosa with various lesions.Results showed that Hppositivity increased in degree with chronic superficial gastritis,chronic atrophic gastritis,dysplasia and adenocarcinoma.The number of PCNA immunostaining positive cells/mm2 increased with progression of lesions,but apoptosis varied slightly.However,in a similar lesions,Hppositive lesions had higher PCNA and lower apoptotic index than Hpnegative.The findings indicated that Hpinfection may have an important biological significance in gastric carcinogenesis.
