腹膜透析液添加葛根素对氧化应激状态的影响

目的:观察在腹膜透析(PD)液中添加葛根素对PD患者腹腔局部及全身氧化应激状态的影响。方法:38例终末期肾病连续性非卧床腹膜透析(CAPD)治疗患者,随机分为实验组和对照组,每组19例。实验组在PD液中添加葛根素注射液(50mg/2 L),对照组PD液中不加药,均行标准CAPD治疗,每次2 L,4次/d,观察16 d。比较两组患者用药前后血清及透出液氧化应激指标:谷胱甘肽(GSH)、总超氧化物岐化酶(T-SOD)、丙二醛(MDA)以及透析充分性指标的变化。结果:用药后实验组患者血清及透出液GSH、T-SOD均较用药前显著升高(P<0.05),透出液MDA在用药后显著降低(P<0.05),患者血清清蛋白、总肌酐清除率(Ccr)、尿素氮清除指数(K t/V)、每天超滤量无明显变化。结论:在PD液中短期应用葛根素,可改善患者腹腔局部及全身的氧化应激状态。

Puerarin ameliorates oxidative stress in patients undergoing continuous ambulatory peritoneal dialysis

Objective:To investigate the impact of Puerarin on oxidative stress in patients undergoing continuous ambulatory peritoneal dialysis(CAPD).Methods: Thirty-eight patients CAPD were randomly divided into two groups,an experimental group(n=19) receiving peritoneal dialysis fluid containing Puerarin(50 mg/2L) in vivo for two weeks and a control group(n=19) receiving dialysis fluid without Puerarin.The concentrations of oxidative stress markers in the serum and effluent such as glutathione(GSH),total-superoxide dismutase(T-SOD),malondialdehyde(MDA),Kt/V and creatinine clearance rate of the two groups(Ccr) were measured and compared before and after the treatment.Results: After the treatment,the concentrations of GSH and T-SOD in the serum and effluent were significantly higher(P<0.05) and that of MDA in the effluent was significantly lower in the experimental group than before the treatment(P<0.05).No significant difference was found in the serum albumin,Kt/V,the volume of ultrafiltration and Ccr.Conclusion: Short-term supplementation of Puerarin to peritoneal dialysis fluid can ameliorate oxidative stress in patients on CAPD without apparent side effects.
