摘要 目的探讨Ezrin蛋白、诱导型一氧化氮合酶(iNOS)在结肠腺瘤组织中的表达及其与腺瘤癌变的关系。方法应用免疫组织化学sP法检测60例结肠管状腺瘤、40例绒毛状及绒毛管腺瘤、30例腺瘤癌变中Ezrin蛋白、iNOS和瞄.67核抗原的表达及细胞定位。结果Ezrin蛋白、iN—OS在结肠管状腺瘤[58.3%(35/60)、50.0%(30/60)]、绒毛状及绒毛管腺瘤[72.5%(29/40),70.0%(28/40)]、腺瘤癌变[96.7%(29/30)、93.3%(28/30)]中的表达分别依次上升,差异有统计学意义(Ezrin蛋白:χ^2=11.600,P=0.005;iNOS:χ^2=8.451,P=0.015),Ezrin蛋白与iNOS表达有相关性(r=0.765,P〈0.01);Ki-67核抗原增殖指数随Ezrin蛋白、iNOS表达上升而增加。结论Ezrin蛋白和iNOS的过表达可能与结肠腺瘤的增殖、恶性转化有关。 Objective To investigate the expression of Ezrin and inducible nitric oxide synthase (iNOS) and their correlation to malignant proliferation of colonic adenoma. Method Expressions of Ezrin, iNOS and nuclear Ki-67 antigen were detected by immunohistochemistry in tubular adenoma (60 cases),villous adenoma (40 cases) and malignant (30 cases ) pleomorphic adenoma. Results Expressions of Ezrin, iNOS in tubular adenoma [ 58.3% ( 35/60 ), 50,0% (30/60) ], villous adenoma [ 72.5% (29/40), 70.00 (28/40) ]and malignant pleomorphic adenoma [ 96.7% (29/30), 93.3% (28/30) ] were gradually increased ( χ^2 = 11.600,P = 0.005 ; χ^2 = 8.451 ,P = 0.015 ). There was a significant positive correlation between the expression of Ezrin and iNOS (r = 0.765 ,P 〈 0.01 ). Nuclear Ki-67 antigen proliferation index was increased with the increasing of Ezrin and iNOS expressions. Conclusion Overexpression of Ezrin and iNOS may promote proliferation and malignant transformation of colonic adenoma.
