摘要
目的:研究良性狭窄胆管组织中CTGF表达的作用.方法:良性狭窄胆管组织23例,正常胆管组织6例,采用免疫组织化学SABC法和原位杂交法检测CTGF和CTGF mRNA的表达.结果:CTGF,CTGF mRNA在良性狭窄胆管组织中主要表达于成纤维细胞胞质内,阳性率分别为82.6%(19/23)和65.2%(15/23);正常胆管组织中少量表达于管壁纤维细胞,阳性率分别为50.0%(3/6)和16.7%(1/6),组间有统计学差异(P<0.05).结论:良性胆管狭窄组织中CTGF呈高表达,是导致胆管良性狭窄的重要因素.
AIM: To explore the role of CTGF in benign biliary stricture. METHODS: Paraffin embedded materials from 23 cases of benign biliary stricture were analyzed for CTGF protein expression by immunohistochemical strept-avidin-biotin complex (SABC) method and CTGF mRNA expression by in situ hybri- dization. Meanwhile, 6 normal cases served as controls. RESULTS: CTGF protein and mRNA were expressed mainly in the cytoplasm of fibroblasts in the tissue of benign biliary stricture, and the positive rates were 82.6% ( 19/23 ) and 65.2% ( 15/ 23 ) respectively. Meanwhile, they were expressed slightly in fibrocytes in the normal bile duct, and the positive rates were 50.0% (3/6) and 16.7% (1/6) respectively. There was a sig- nificant difference between the 2 groups (P 〈 0.05). CONCLU- SION: The high expression of CTGF plays an important role in the formation of benign biliary stricture.
