摘要: 摘要:目的:研究从胆囊粘膜典型增生到胆囊癌的发展过程中肿瘤坏死因子( TNF) 的表达,进一步探讨它们在胆囊癌发生、发展中的意义。方法:用原位杂交及免疫组织化学方法检测胆囊结石引起的粘膜典型增生、非典型增生及胆囊癌的TNFmRNA、TNF 蛋白的表达。结果: ①TNFmRNA 在胆囊粘膜典型增生、非典型增生及胆囊癌组织上皮细胞或癌细胞和单个核细胞(MNC) 的阳性表达率及表达细胞数目均逐级增高。②在胆囊癌组织中,癌细胞及MNC 表达TNFmRNA 的细胞表达数目随肿瘤进展而增多(P < 0. 01) 。③TNF 蛋白与TNFmRNA 表达区域相似,阳性表达率较高。④癌细胞和MNC 的TNFmRNA及蛋白表达均呈正直线相关。结论: TNF 参与了胆囊结石致癌的发病过程,并与胆囊癌的进展有关。

Abstract: Abstract : Purpose : To study the expression of TNF -αmRNA and TNF -αprotein in the development from hyperplasia , dysplasia to carcinoma of gallbladder mucosa and to discuss the pathogenesis of gallbladder mucosa and to discuss the pathogenesis of gallbladder carcinoma. Methods : In situ hybridization and immunohistochemist ry were used to detect the expression of TNF -αmRNA , TNF -αprotein in mucosa of hyperplasia , dysplasia and carcinoma of gallbladder. Results : ①The percentages of positive cells and the numbers of positive cells/per high power field (HPF) which expressed TNF - αmRNA in hyperplasia , dysplasia and carcinoma of gallbladder mucosa cell and mononuclear cells(MNC) were increasing. ②The numbers of carcinoma cells and MNC/ HPF which expressed TNF -αmRNA increased with increasing tumor grades and size. ③The pattern of TNF -αprotein expression was similar to that of TNF -αmRNA , but more f requent and widespread. ④There was a positive linear correlation between tumor cells and MNC of TNF -αmRNA and TNF -αexpression. Conclusion : TNF -αwas involved in the pathogenesis of gallbladder carcinoma induced by gallstone and the TNF -α expression in cancer cells may possibly be a marker for tumor staging.
