摘要：

 【摘要】 目的  探讨Epstein-Barr virus（EBV）、幽门螺旋杆菌（Hp）感染与胃癌发生的关系及二者的相互作用。 方法  采用聚合酶链反应（PCR）和原位杂交（ISH）技术检测100例胃癌组织（胃癌组）及82例胃炎组织（胃炎组）中EBV的感染情况，采用PCR技术检测Hp感染情况，分析EBV、Hp感染与胃癌患者临床病理特征的关系及二者的相关性。 结果  胃癌组EBV和Hp的感染阳性率均高于胃炎组（9.0%vs0和56.0%vs40.2%,均P＜0.05）。贲门胃体癌较胃窦癌EBV感染率高（16.3%vs2.0%，P＜0.05），低分化癌较中高分化癌EBV、Hp感染率高（15.7%vs2.0%和66.7%vs44.9%,均P＜0.05），不同性别、年龄、民族及有无淋巴结转移间EBV、Hp感染率差异无统计学意义，不同发生部位间的Hp感染率差异无统计学意义。胃癌组EBV与Hp感染无相关性（r=0.137，P＞0.05）。结论  EBV、Hp感染是胃癌发生的2个独立因素，二者均与胃癌的恶性演进有关

Abstract:

[Abstract]  Objective  To investigate the correlation between Epstein-Barrvirus (EBV) and H.pylori (Hp) infection
and gastric cancer.  Methods  The EBV infection was examined by polymerase chain reaction (PCR) and in situ hybridization (ISH) in 100samples of gastric cancer tissue and82samples of gastritis tissue. The Hp infection was detected by PCR. The correlation between EBV and Hp infection and clinical and pathological features was analyzed in patients with gastric cancer.  Results  The positive rates of EBV and Hp were significantly higher in gastric cancer tissues than those in gastritis tissues (9.0%vs0and56.0%vs40.2%,P＜0.05). There was significantly higher infection rate in EBV in cardia gastric can-cer than that of gastric cancer (16.3%vs2.0%，P＜0.05). There were significantly higher infection rates in EBV and Hp in poorly differentiated carcinoma than those of well-differentiated carcinoma (15.7%vs2.0% and66.7%vs44.9%,P＜0.05). There were no significant differences in EBV and Hp infection between gender, age, nationality and lymph node metastasis (P＞0.05). There was no significant difference in Hp infection between different parts of gastric cancer. There was no correlation between EBV and Hp infection in gastric cancer tissues (r=0.137, P＞0.05).  Conclusion  EBV and Hp infection aretwo independent factors in the development of gastric cancer, and both of them are associated with the malignant evolution of gastric cancer.
