摘要
目的 :研究结缔组织生长因子 (connectivetissuegrowthfactor,CTGF)在原发性肾小球肾炎小管间质病变中的表达及其与肾间质纤维化之间的关系。  方法 :选择不同类型原发性肾小球肾炎患者 42例 ,根据小管间质病变分级分为四组 :0级 8例 ,1级 12例 ,2级 12例 ,3级 10例。应用免疫组织化学方法分别观察四组中CTGF、TGF β1、FN和COL Ⅲ的表达 ,并将CTGF表达水平与患者血肌酐 (SCr)和内生肌酐清除率 (Ccr)进行比较。  结果 :肾小管上皮细胞 (从近端小管到髓质集合管 )是间质中CTGF的主要来源 ,CTGF表达量与肾小管间质病变程度成正比 (P=0 0 0 5 )。此外 ,CTGF与TGF β1、FN和COL Ⅲ的表达量成正相关 (P均 <0 0 5 ) ;与患者Ccr升高水平成正比 (P <0 0 0 5 )。  结论 :随着慢性肾小管间质病变程度加重 ,CTGF蛋白质分子表达量显著增加 ,它可能在肾间质纤维化形成过程中起重要作用。CTGF作为TGF β1的下游因子 ,可能通过促进细胞外基质 (ECM)如FN和COL Ⅲ等合成增加 ,参与肾间质纤维化发生。
