摘要: 探讨缓释碱性成纤维细胞生长因子(basic fibroblast growth factor, bFGF)对胆管损伤修复术后胆管癖痕形成的预防作用.通过分组实验,制备猪胆管部分缺损模型,运用加载缓释bFGF胶原膜及空白胶原膜修复缺损.比较术后1、2、3个月的肝功能变化并用病理切片和兔疫组化染色比较胆管愈合、
胶原增生及肌成纤维母细胞(myofibroblast, MFB)的表达情况.术后6个月胆道造影观察狭窄形成情况.结果显示:经缓释bFGF治疗后,胆管未出现癖痕性狭窄.与空白胶原膜组相比,胆汁淤积酶学指标中GGT和TBA显著降低,免疫组化提示MFY的表达显著降低,胶原排列及结构更接近于正常胆管.证明运用缓释bFGF胶原膜治疗胆管缺损可通过加速胆管愈合及下调MFB的表达有效的预防胆管损伤修复术后胆管瘫痕的形成.
