摘要

目的 :探讨环氧化酶 - 2 （cyclooxygenase - 2

COX - 2 ）在胃癌组织中的表达与癌细胞增殖和凋亡的关系。方法 :采用免疫组织化学的方法检测 4 3例胃癌患者COX - 2和增殖细胞核抗原（PCNA）的表达

用TUNEL法检测原位细胞凋亡的情况。分别计算细胞增殖指数（MI）和凋亡指数（AI）。结果 :胃癌组织COX - 2表达的阳性率为 6 0 .4 7%

明显高于对照组（P <0 .0 1）。COX - 2的高表达与胃癌淋巴结的转移和临床分期有关

与肿瘤大小、浸润深度、分化程度均无关。COX - 2阳性胃癌组中MI高于COX - 2阴性胃癌组

而AI却低于COX - 2阴性胃癌组（P均 <0 .0 1）。结论 :COX - 2的过度表达可促进胃癌细胞增殖、抑制细胞凋亡

在胃癌的发生、发展过程中起着重要的作用。

Abstract

Objective:To investigate the expression level of COX-2 and their effects on cell proliferation activity and apoptosis degree in gastric cancinoma.Methods:The expression of COX-2

proliferating cell nuclear antigen(PCNA) and apoptosis in 43 cases of gastric cancer were studied by immunohistochemistry and TUNEL methods

and the proliferation index (PI) and apoptotic index(AI) were defined respectively.Results:The positive expression rate of COX-2 was 60.47% in gastric carcinoma tissue.It was significantly higher than that in the control group.Overexpression of COX-2 in gastric carcinoma was related to its lymph node metastasis and clinical stage

but it did not correlate with the size of tumor

depth of the invasion and the differentiation degree( P >0.05).In the group with COX-2 positive expression AI was higher than that of the group with COX-2 negative expression

whereas AI was higher in the latter group than in the former ( P <0.01).Conclusion:The expression level of COX-2 may have a close correlation with cell proliferation and apoptosis and they may participate in oncogenesis and progression of gastric carcinoma.
