糖尿病视网膜病变 (diabetic retinopathy,DR)的主要病理改变是早期微血管的闭塞和晚期纤维血管的增生。碱性成纤维细胞生长因子 (basic fibroblastgrowth factor,b FGF)是一种潜在的有丝分裂原 ,相对分子质量为 170 0 0～ 2 40 0 0 [1 ] ,在 DR的发病机制中具有重要作用 [2 ,3
The main pathological changes of diabetic retinopathy (DR) are the occlusion of early microvascular and the proliferation of advanced fibrovascular. Basic fibroblast growth factor (b FGF) is a potential mitogen with a relative molecular mass of 170 0-2 240 0 [1] and plays an important role in the pathogenesis of DR [2 3
