1、临床医学论文•丹参注射液对梗阻性肾病大鼠肾功能及TGFB1表达的影响作者:桂泽红代睿欣邓时贵韩凌孙静石灵春【摘要】〔目的〕观察丹参注射液对梗阻性肾病大鼠肾组织转化生长因子B1(TGFB1)表达、肾功能及肾病理组织学的影响。〔方法〕采用半结扎法建立尿路梗阻性肾病人鼠模型,观察丹参注射液治疗性给药对尿路梗阻性肾病人鼠肾组织TGF/31表达(RTPCR法)、血清肌肝(碱性苦味酸法)、尿素氮(尿素酶法)及肾病理组织学(常规He染色)的影响。〔结果〕I、大鼠尿路梗阻3d,模型对照组血清肌阡、尿素氮均升高,其中尿素氮升高明显,有显著性差异,但血肌肝升高
2、不明显;丹参治疗组结果类似。术后3d模型对照组和丹参治疗组血清肌肝、尿素氮比较,均P>0.05。大鼠尿路梗阻14d血清肌酊、尿素氮持续升高。丹参治疗组血清肌肝、尿素氮均降低,其中尿素氮降低明显,但仍高于假手术组。人鼠尿路梗阻56d,模型对照组血清尿素氮在高位水平,而血肌酊变化不明显;丹参治疗组结果类似。2、与假手术组比较,模型组肾TGFBImRNA呈高表达趋势;丹参治疗组各时点对肾组织TGFBImRNA表达未见明显影响,但趋势显示丹参治疗给药可能有轻微抑制TGF/3ImRNA表达。3、病理结果:模型组肾小球及肾小管呈固缩性改变,肾小管广泛坏
3、死;丹参治疗组肾小球及肾小管呈固缩性改变,肾小球个别坏死。〔结论〕尿路梗阻性肾病大鼠长期注射丹参注射液有助于减少肾小球坏死、改善肾脏功能。【关键词】梗阻性肾病;丹参注射液;转化生长因子B1;大鼠Abstract:[Objective]ToobservetheeffectofSalviaInjectiononobstructivenephropathyrats*kidneyfunction,TGF/31expression,pathologyandhistology,primarilydiscussitsprotectivemechanism
