1、化瘀通絡中藥對糖尿病腎病大鼠腎組織CTGFmRNA表達的影響作者:尹智煒高俊杰陳志強孫玉鳳丁奇峰王月華張江華【摘要】 觀察化瘀通絡中藥—腎絡通對實驗性大鼠糖尿病腎病(DN)模型腎功能及腎組織結締組織生長因子(CTGF)mRNA表達的影響。方法SD大鼠40只隨機分為正常組、模型組、對照組和中藥組,模型組、對照組和中藥組應用鏈脲佐菌素(STZ)60mg/kg一次性腹腔注射制備大鼠糖尿病模型。中藥組給予腎絡通煎劑灌胃25g/(kg·d),對照組給予貝那普利水溶液10mg/(kg·d),正常組和模型組給予等量0.
2、9%氯化鈉注射液灌胃。檢測各組大鼠24h尿蛋白、血清尿素氮(BUN)、肌酐(Cr)和腎組織CTGFmRNA的表達。結果模型組24h尿蛋白、BUN、Cr和腎組織CTGFmRNA的表達均顯著高于正常組(P<0.01);對照組和中藥組24h尿蛋白、BUN、Cr和腎組織CTGFmRNA的表達與模型組相比顯著降低(P<0.01)。結論化瘀通絡中藥能夠顯著減少DN模型大鼠24h尿蛋白,保護DN模型大鼠腎臟功能,并可從基因水平顯著降低腎組織CTGF的表達,提示下調(diào)CTGF的表達可能是化瘀通絡中藥保護DN模型大
