目的 探讨滋肾育胎丸对雷公藤多甙诱导的卵巢储备功能下降(DOR)大鼠模型卵泡凋亡及相关蛋白表达的影响.方法 将40只大鼠分为对照组、模型组、补佳乐组及滋肾育胎丸低、高剂量组,每组8只.采用灌胃雷公藤多甙片建立大鼠DOR模型,HE染色检测大鼠卵巢病理,对各级卵泡进行计数,免疫组织化学法检测各组大鼠卵泡、卵巢间质的Bcl-2、Bax蛋白表达变化.结果 与对照组比较,模型组大、小卵泡数量减少,闭锁卵泡的数量增加,并且在各类卵泡中Bcl-2表达均降低,Bax表达均升高,差异有统计学意义(P＜0.05).与模型组比较,滋肾育胎丸高、低剂量及补佳乐组大鼠的大、小卵泡数量增加,闭锁卵泡数量减少,大、小卵泡的Bcl-2表达均有明显升高,Bax表达均明显降低,差异均有统计学意义(P＜0.05).结论 滋肾育胎丸可通过上调Bcl-2蛋白和下调Bax蛋白表达,抑制卵泡过早、过快凋亡,从而起到治疗DOR的作用.%Objective To investigate the effect of Zishen Yutai Pills on follicle apoptosis and related protein expression in diminished ovarian reserve(DOR) rat model induced by tripterygium glycosides.Methods Forty rats were divided into the control group,model group,progynova group,and Zishen Yutai Pills high and low dose groups,8 cases in each group.Tripterygium Wilfordii Glycosides Tablets were given by gavage for establishing the rat DOR model.Then the HE staining was used to detect the pathological morphology of rat ovary.All levels of follicles were counted.Expression levels of Bcl-2 and Bax protein in follicle and ovarian stroma of each group were detected by using the immunohistochemical method.Results Compared to the control group,the number of great and small follicles in the model control group was decreased,number of atretic follicles was increased,Bcl-2 expression in all kinds of follicles was decreased,and Bax expression was increased,the differences were statistically significant(P＜0.05).Compared to the model group,the number of great and small follicles in the Zishen Yutai Pills high and low dose groups and progynova group was increased,number of atretic follicles was decreased,the Bcl-2 expression in great and small follicles was significantly increased and the Bax expression was significantly decreased,the differences were statistically significant(P＜0.05).Conclusion Zishen Yutai Pills can inhibit the premature and too fast follicles apoptosis by upregulating the expression of Bcl-2 protein and down-regulating the expression of Bax protein,thus plays the effect for treating DOR.
