• 【摘要】目的    探究解毒祛瘀滋阴方对系统性红斑狼疮（SLE）小鼠肠道菌群的调节作用及对肾脏损伤情况的影响。方法    选取30只MRL/lpr雌性SLE小鼠作为研究对象。完全随机分为A、B、C 3组，每组10只。A组小鼠采用醋酸泼尼松1次/d，灌胃5周，B组小鼠给予解毒祛瘀滋阴方1次/d，灌胃5周，C组小鼠作为对照组，以0.9%氯化钠注射液1次/d，灌胃5周。比较3组小鼠治疗前后的条件致病菌(大肠埃希菌、肠球菌、拟杆菌)和有益菌（双歧杆菌、乳酸杆菌）的菌落数量及肾脏损伤情况（24 h尿蛋白定量、尿肌酐、尿胱抑素C水平）。结果    治疗前3组小鼠粪便的各菌落数量差异无统计学意义（P＞0.05）。治疗后，A、B组的大肠埃希菌、肠球菌、拟杆菌菌落数量较治疗前明显降低，双歧杆菌、乳酸杆菌菌落数量较治疗前明显增加，与C组比较差异均有统计学意义［（322±8）、（305±7）CFU/g比（359±13）CFU/g，（318±8）、（295±7）CFU/g比（354±13）CFU/g，（326±10）、（298±8）CFU/g比（347±12）CFU/g，（308±9）、（337±10）CFU/g比（281±12）CFU/g，（316±9）、（344±10）CFU/g比（285±11）CFU/g］（均P＜0.05），并且B组比A组的条件致病菌菌落数量更少，有益菌菌落数量更多，A、B组之间比较差异有统计学意义（P＜0.05）。治疗前3组小鼠的24 h尿蛋白定量、尿肌酐、尿胱抑素C差异无统计学意义（P＞0.05）。治疗后，A、B组小鼠的24 h尿蛋白定量、尿肌酐、尿胱抑素C明显降低，与C组比较差异有统计学意义（P＜0.05），并且B组低于A组，A、B组之间比较差异有统计学意义（P＜0.05）。结论    解毒祛瘀滋阴方对SLE小鼠肠道菌群的调节作用较好，并且能够缓解肾脏损伤情况，整体治疗效果理想。

  【Abstract】Objective     To investigate the effect of Jiedu Quyu Ziyin prescription on intestinal microflora regulation and renal injury in mice with systemic lupus erythematosus(SLE). Methods    Thirty MRL/lpr female mice with SLE were randomly divided into group A, B, C with 10 mice in each group. Group A had intragastric administration of prednisone acetate 1 time/d for 5 weeks; group B had intragastric administration of Jiedu Quyu Ziyin prescription 1 time/d for 5 weeks; group C had intragastric administration of 0.9% sodium chloride 1 time/d for 5 weeks. Colony numbers of conditional pathogenic bacteria（escherichia coli, enterococcus, bacteroid） and beneficial bacteria（bifidobacteria, lactobacilli） and indicators of renal injury（24 h urinary protein, urine creatinine, urinary cystatin C） were analyzed. Results    There were no significant differences of colony numbers among groups before treatment（P＞0.05）. After treatment, colony numbers of escherichia coli, enterococcus and bacteroid in group A and B were significantly lower and colony numbers of bifidobacteria and lactobacilli were significantly higher than those in group C［（322±8）,（305±7）CFU/g vs （359±13）CFU/g; （318±8）,（295±7）CFU/g vs （354±13）CFU/g; （326±10）,（298±8）CFU/g vs （347±12）CFU/g; （308±9）,（337±10）CFU/g vs （281±12）CFU/g; （316±9）,（344±10）CFU/g vs （285±11）CFU/g］(P<0.05); colony numbers of conditional pathogenic bacteria in group B were significantly lower and colony numbers of beneficial bacteria were significantly higher than those in group A(P<0.05). There were no significant differences of 24 h urinary protein, urine creatinine and urinary cystatin C among groups before treatment(P>0.05). After treatment, levels of 24 h urinary protein, urine creatinine and urinary cystatin C in group A and B were significantly lower than those in group C(P<0.05) and the levels in group B were significantly lower than those in group A(P<0.05). Conclusion    Jiedu Quyu Ziyin prescription can improve intestinal microflora regulation and reduce renal injury in SLE mice.
