摘要 目的检测河南贲门癌高发区贲门癌组织中环氧合酶-2(COX-2)蛋白的表达。方法应用免疫组化ABC方法检测37例贲门癌患者癌组织、癌旁不典型增生组织和正常组织中COX-2蛋白的表达。结果贲门正常组织中COX-2蛋白阳性表达率最低,从正常组(1/30,3%)→不典型增生组(4/16,25%)→贲门癌组(16/30,43%),COX-2蛋白阳性表达率呈逐渐升高趋势(χ2=10.991,P<0.05)。结论COX-2可能在贲门上皮癌变过程中起重要作用。 Aim: To detect the expression of COX-2 in gastric eardia adenoeareinoma (GCA) tissue from the patients at high incidence area in Henan province. Mothods:Immunohistoehemistry method (ABC) was applied to detect the expression of COX-2 in 37 eases of GCA tissue, paraeaneerous atypical hyperplasia tissue and normal tissue, respectively. Results: The positive rate of COX-2 was very low in the normal gastric eardia epithelia and increased apparently with the lesion progressing from normal ( 1/30,3% ) , to atypical hyperplasia tissue (4/16,25%) to GCA tissue ( 16/30,43% ) (χ^2 = 10. 991 ,P 〈0.05). Conclusion: COX-2 may play an important role in the carcinogenesis of GCA.
