摘　　要：目的:探讨肌源性干细胞(MDSCs)和脂肪源性干细胞(ADSCs)分别治疗尿道括约肌功能障碍型压力性尿失禁(ISD)大鼠模型的效果及差异。方法:分离大鼠的MDSCs和ADSCs并鉴定其种类。构建ISD小鼠模型,A组ISD大鼠的膀胱颈部和尿道外括约肌注射MDSCs,为MDSCs组(20例);B组注射ADSCs,为ADSCs组(20例);C组注射D-Hanks培养液作对照组(20例)。3组大鼠分别于细胞注射前及第15、30、60天,使用尿动力学检测仪评估其排尿功能。结果:尿动力学检查显示与对照组比较,MDSCs注射治疗和ADSCs注射治疗均都改善了ISD大鼠的排尿功能,且MDSCs治疗组疗效改善效果更明显。MDSCs组及ADSCs组中的最大尿道压(MUP)(16.95±3.80、12.71±3.30)和漏尿点压力(LPP)(58.49±7.60、45.61±8.80)明显高于对照组(9.37±1.60、28.77±5.10,P<0.05),且细胞移植后30 d及60 d较细胞移植前明显高,较对照组最大膀胱容量(MCC)(1.86±0.9)比较,MDSCs组及ADSCs组中的MCC(0.95±0.60、1.30±0.20)明显降低(P<0.05)。结论:MDSCs和ADSCs注射对ISD的治疗有明显的作用,且MDSCs注射效果优于ADSCs。Objective To investigate the effects and differences of muscle-derived stem cells(MDSCs)and adipose-derived stem cells(ADSCs)in treating urethral sphincter dysfunction stress urinary incontinence(ISD)in rats.Methods MDSCs and ADSCs of rats were isolated and identified.After establishing ray ISD model,the rats injected with MDSCs into bladder neck and external urethral sphincter served as MDSCs group(20 cases),and those injected with ADSCs served as ADSCs group(20 cases).The animals injected with D-Hank’s culture solution served as control group(20 cases).The micturition function of three groups was evaluated by urodynamic detector before and 15,30 and 60 days after cell injection,respectively.Then the rats were killed.Results Urodynamic examination showed that as compared with the control group,both MDSCs injection therapy and ADSCs injection therapy improved the micturition function of ISD rats,and the therapeutic effect of MDSCs treatment group was more obvious.The maximum urinary pressure(MUP)in MDSCs group and ADSCs group was(16.95±3.80)and(12.71±3.30),and the leak point pressure(LPP)was(58.49±7.60)and(45.61±8.80),which were significantly higher than in the control group(9.37±1.60,28.77±5.10).At 30th and 60th after the transplantation,the Maximum bladder capacity(MCC)in MDSCs group and ADSCs group decreased significantly as compared with control group(0.95±0.60 and 1.30±0.20 vs.1.86±0.90,P<0.05).Conclusion Injection of MDSCs and ADSCs has obvious effects oi the treatment of ISD,and efficacy of MDSCs injection is better than ADSCs injection.
