摘要: 目的 探讨温肾养血方提高高龄雌鼠卵母细胞质量和胚胎发育潜能的作用机制。方法 按随机数字表法将8月龄ICR小鼠分为对照组、血清促性腺激素(pregnant mare serum gonadotropin,PMSG)组、温肾养血组、温肾组、养血组,观察用药后各组受精率和卵裂率,卵母细胞和受精卵线粒体的表达情况。结果 温肾养血组、温肾组、养血组的受精率和卵裂率明显高于对照组和PMSG组(P<0.05),温肾养血组的受精率和卵裂率最高(P<0.05)。2细胞率、4细胞率、8细胞率、桑葚胚率和囊胚率,温肾养血组均比PMSG组高且差异有统计学意义(P<0.05)。卵母细胞和受精卵中的线粒体DNA拷贝数温肾养血组最高,与对照组比较,差异有统计学意义(P<0.05)。结论 温肾养血方可能通过调控卵母细胞线粒体DNA拷贝数提高卵母细胞质量和胚胎发育潜能。

Abstract: Objective To explore the mechanism of Wenshen Yangxue Decoction in improving oocyte quality and embryo development potential in older female rats.Methods Eight-month-old ICR mice were divided into control group, pregnant mare serum gonadotropin (PMSG) group, Wenshen decoction, Yangxue decoction and Wenshen Yangxue decoction according to random number table method. The fertilization rate and cleavage rate of every group after treatment were recorded, and the expression of mitochondria in oocyte and fertilized eggs were examined. Results The fertilization rate and cleavage rate of Wenshen Yangxue decoction, Wenshen decoction and Yangxue decoction were significantly higher than those of the control group and PMSG group (P<0.05). The fertilization rate and cleavage rate of Wenshe Yangxue decoction were the highest (P<0.05). The 2 cell rate, 4 cell rate, 8 cell rate, morula rate and blastocyst rate of Wenshen Yangxue decoction were higher than in the PMSG group (P<0.05). The mitochondrial DNA copy number in oocytes and fertilized eggs of Wenshen Yangxue decoction was the highest of the five groups, which was statistically significant compared with the control group(P<0.05). Conclusion Wenshen Yangxue decoction may improve oocyte quality and embryo development potential by regulating oocyte mitochondrial DNA copy number.
