| 摘 要： | 目的探讨抗生素联合皮质激素防治肾盂肾炎延迟治疗时肾皮质瘢痕的效用及机制。方法大鼠分为正常组（A）,模型组（B）、左旋氧氟沙星及时治疗组（C）、左旋氧氟沙星加激素延迟治疗组（D）、左旋氧氟沙星延迟治疗组（E）,分别于30d、60d、90d测量各组肾小管功能（尿NAG/Cr）、肾功能（Scr、BUN）、24h尿蛋白定量,第90天统计各组肾皮质瘢痕率,RT-PCR及免疫组化测量肾组织TGF-β1mRNA及蛋白水平表达。结果B组第90天出现尿NAG/Cr显著升高,与A、C、D组比较有显著性差异（P﹤0.01）;实验期间各组肾功能、24h尿蛋白均无显著差异。C、D组二级及以上瘢痕发生率显著减少（P﹤0.05）,D组总体瘢痕率显著减少。RT-PCR及免疫组化提示各组较A组TGF-β1表达增加;相对于B组,C、D组TGF-β1肾内表达显著抑制,E组无此作用。结论延迟治疗时抗生素联合皮质激素有助于减少肾皮质瘢痕发生,单独使用抗生素无此作用。

| Abstract: | Objective To explore the effects of antibiotics combined with corticosteroid on suppressing renal scarring in treatment-delayed chronic pyelonephrits (CPN). Methods An experimental CPN model in rats was developed. All animals were divided into five groups including group A (normal group), group B (model group), group C (Lev- ofloxacin Lactate/LFL treatment given 24h after operation), group D (delayed treatment with LFL and methylprednisone giv- en 72h after operation) and group E (delayed treatment with LFL... |
