[ 摘要] 目的 COX - 2 的表达与胃癌的关系及临床意义 。 方法 探讨 NF - кB、 采用
免疫组织化学方法( S - P 法) 对胃癌组织、 正常胃黏膜中 NF - кB p65 及 COX - 2 蛋白表达进 行检测。结果 NF - кB p65 蛋白和 COX - 2 蛋白在胃癌组织中的阳性表达率分别为 67% 和 60% , 2 者比较均有显著性差异 ( P 均 < 正常胃黏膜中的阳性表达率分别为 21% 和 18% , 0. 01 ) 。在低分化组的阳性表达率分别为 79% 和 72% , 高 / 中分化组的阳性表达率分别为 53% 和 47% , 2 者比较均有显著性差异( P 均 < 0. 05 ) ; 在浸润深度为 T3 + T4 组的阳性表达率 T1 + T2 组的阳性表达率分别为 22% 和 22% , 2 者比较均有显著性差异 分别为 73% 和 66% , ( P < 0. 01 ) ; 在临床Ⅲ ~ Ⅳ 期组的阳性表达率分别为 78% 和 74% , Ⅰ ~ Ⅱ 期组的阳性表达率 2 者比较均有显著性差异( P 均 < 0. 01 ) 。不同性别、 分别为 48% 和 37% , 年龄、 肿瘤部位及大体分型胃癌组织中 NF - кB p65 和 COX - 2 蛋白的表达无显著性差异( P 均 > 0. 05 ) 。胃癌组织中 NF - кB p65 和 COX - 2 蛋白的表达呈明显 P < 0. 01 ) 。结论 正相关( r s = 0. 539 , 淋巴转移密切相关。 [ 关键词] 胃癌; 核转录因子 - кB; 环氧合酶 - 2 ; 免疫组织化学 [ 中图分类号] R735. 2 [ 文献标识码] A [ 文章编号] 1008 - 8849 ( 2012 ) 15 - 1597 - 05 Study on expressions of NF - кB and COX - 2 in gastric carcinoma Liu Hongbo,Yang An,Qin Zhishan,Tian Yunxiao,Zhai Lifang ( Handan Central Hospital,Handan 056001 ,Hebei,China) Abstract : Objective It is to approach the relationships of expression of NF - кB, COX - 2 with gastric carcinoma and it’ s clinical significance. Methods The S - P immunohistochemical technique was used to detect the expressions of protein NF - кB p65 and COX - 2 in gastric carcinoma tissues and normal gastric mucosa. Results The positive expression rate of NF - кB p65 and COX - 2 was 67% and 60% respectively in gastric carcinoma,and was 21% and 18% respectively in normal gastric mucosa,there were significant differences ( P < 0. 01 ) . It was 79% and 72% respectively in poorly differentiated and was 53% and 47% in moderately and well differentiated,there were significant differences ( P < 0. 05 ) . It was 73% and 66% respectively in T3 + T4 and was 22% and 22% respectively in T1 + T2 , there were significant differences ( P < 0. 01 ) . It was 78% and 74% respectively in Ⅲ ~ Ⅳ grade and was 48% and 37% respectively in Ⅰ ~ Ⅱ grade,there were significant differences ( P < 0. 01 ) . There was no significant difference in expressions of protein NF - кB p65 and COX - 2 in gastric carcinoma tissues between distinct genders,age,locus and typing ( all P > 0. 05 ) . The expression of NF - кB p65 was positively correlated to COX - 2 ( r s = 0. 539 ,P < 0. 01 ) . Conclusion The expressions of NF - кB and COX - 2 are higher in gastric carcinoma tissues,so they are related to genesis,development,invasion and metastasis of gastric carcinoma.
