目的:探讨 Toll 样受体4(TLR4)与核因子-κB (NF-κB)蛋白在非小细胞肺癌(NSCLC)组织中的表达及临床意义。方法采用免疫组化 SP 法检测58例 NSCLC 癌组织及癌旁正常肺组织中 TLR4与 NF-κB 蛋白的表达,分析其与NSCLC临床病理特征的关系及两者间的相关性。结果TLR4和NF -κB 蛋白在NSCLC 组织中的阳性表达率(60.3%和67.2%)明显高于癌旁正常肺组织中的阳性表达率(15.5%和8.6%),差异均有统计学意义。在 NSCLC 不同分化组织中 TLR4蛋白阳性表达率比较差异有统计学意义;不同组织学类型中 NF-κB 蛋白阳性表达率比较差异有统计学意义,且在腺癌中的阳性率(80.6%)明显高于鳞癌(51.9%)。在 NSCLC 组织中,TLR4与 NF-κB 蛋白表达密切相关。结论TLR4和 NF-κB 蛋白可能参与了 NSCLC 的浸润和转移,对临床判断 NSCLC 组织的分化程度、恶性程度及组织分类具有一定参考意义。

Objective To investigate the expression and clinical significance of Toll-like re-ceptor 4 (TLR4)and nuclear factor-kappaB (NF-κB)in non-small cell lung cancer (NSCLC)tissue. Methods The immunohistochemical SP method was used to examine the protein expressions of TLR4 and NF-κB in 58 cases of NSCLC tissue and tissue adjacent to cancer.The relationship between pro-tein expressions of TLR4 and NF-κB and NSCLC clinical pathological characteristics as well as both correlations were analyzed.Results The positive rates of TLR4 and NF-κB protein in NSCLC tissue weresignificantly higher than in the tissue adjacent to cancer (6 0 .3 % vs .1 5 .5 % and 6 7 .2 % vs . 8.6%),with statistical significance.There was statistical significance by comparison to the positive rates of TLR4 protein in different differentiated tissues and NF-κB protein expression in different histo-logical types in NSCLC,and the positive rate of NF-κB protein in adenocarcinoma was obviously higher than in squamous carcinoma (80.6% vs.51.9%).The expression of TLR4 protein was closely asso-ciated with that of NF-κB protein.Conclusion TLR4 and NF-κB may participate in NSCLC infiltra-tion and metastasis,which provides a certain references for judging the differentiated and malignant de-grees as well as histological types in NSCLC tissue.
