文题释义:
淫羊藿:
中国传统的补肾中药,来源于小檗科(Berberi-daceae)淫羊藿属(Epimedium L.)植物,具有补肾阳、强筋骨、祛风湿之功效。现代药理研究表明,淫羊藿有效成分及其提取物具有广泛的生理活性,其研究范围主要集中在对骨系统、免疫调节和延缓衰老、生殖系统、心血管系统等方面。
阿霉素肾病动物模型:于20世纪80年代初期建立,是目前公认的能较好模拟人类慢性肾脏病的动物模型,在肾脏病研究领域已广泛应用。SD、Wistar大鼠与BALB/小鼠对造模药物敏感、模型特征出现迅速、持续和稳定,同时还有培育简便、生存能力强等优势,在现今阿霉素肾病模型的实验研究中得到较多采用。阿霉素肾病为进展性肾病,其病理类型与阿霉素剂量、造模周期密切相关,如病变早期以微小病变型肾病为主,随着肾脏病理改变的延续,中晚期常发展为局灶节段性肾小球硬化,甚至弥漫性肾小球硬化。

 

摘要
背景:
研究表明,骨髓间充质干细胞具有分化能力,可能治疗肾病损伤;而淫羊藿也具有良好的抗炎作用和免疫修复作用。
目的:观察淫羊藿灌胃联合骨髓间充质干细胞移植对阿霉素肾病大鼠肾脏病变的治疗作用。
方法:将50只大鼠随机分为对照组、模型组、骨髓间充质干细胞+淫羊藿组、骨髓间充质干细胞组和淫羊藿组,各10只。后4组大鼠于尾静脉注射盐酸阿霉素制备肾病大鼠模型;对照组注射等体积生理盐水。模型成功造模24 h后,骨髓间充质干细胞+淫羊藿组经尾静脉注射骨髓间充质干细胞,同时灌胃淫羊藿水煎液1 mL/d,连续1周。骨髓间充质干细胞组经尾静脉注射骨髓间充质干细胞。淫羊藿组灌胃淫羊藿水煎液1 mL/d,连续1周。模型组注射等量生理盐水同时灌胃等量生理盐水。对照组大鼠不作任何处理。
结果与结论:①与模型组相比,骨髓间充质干细胞和/或淫羊藿治疗后,大鼠肾脏组织损伤明显减轻,尿蛋白含量减少;②与模型组相比,骨髓间充质干细胞+淫羊藿组和淫羊藿组大鼠血浆白蛋白及血液中过氧化氢酶含量显著升高,血清胆固醇、三酰甘油及丙二醛水平显著降低;③与模型组相比,骨髓间充质干细胞+淫羊藿组和骨髓间充质干细胞组大鼠肾脏组织中转化生长因子β1 mRNA表达显著下降;④结果提示淫羊藿联合骨髓间充质干细胞治疗肾病效果优于单一使用淫羊藿或骨髓间充质干细胞。

Abstract:

BACKGROUND: A large number of studies have shown that bone marrow mesenchymal stem cells (BMSCs) with differentiation ability can be used to treat kidney injury. Epimedium has good anti-inflammatory and immune restoration ability.
OBJECTIVE: To observe the effect of epimedium with BMSC transplantation on rat’s kidney disease caused by adriamycin nephrosis.
METHODS: Fifty rats were equivalently randomized to receive no treatment in control group, tail vein injection of normal saline plus intragastric injection of normal saline in model group, tail vein injection of BMSCs plus intragastric injection of epimedium decoction in combined group, tail vein injection of BMSCs in BMSCs group, and intragastric injection of epimedium decoction in epimedium group. Rat models of adriamycin nephrosis were made in the latter four groups through tail vein injection of doxorubicin hydrochloride, while rats in the control group were only given the same volume of normal saline. Twenty-four hours after modeling, rats in the latter four groups began to be given the corresponding treatments. Epimedium decoction was given in the combined and epimedium groups at a dose of 1 mL/d, for consecutive 1 week. 
RESULTS AND CONCLUSION: Compared with the model group, mitigated kidney injury and reduced urinary protein level were found in rats undergoing BMSCs and/or epimedium decoction treatment; the levels of plasma albumin and catalase were significantly increased in the combined group and epimedium group, while the levels of serum cholesterol, triglycerides and malondialdehyde decreased; the mRNA expression of transforming growth factor β1 in the kidney tissues was dramatically declined in the combined group and BMSC group. To conclude, the combined use of epimedium and BMSCs is superior to their use alone in the treatment of kidney disease.
