Abstract:
Objective To observe the effect of Yiqixue Buganshen Recipes(YBR), the compound recipes of Chinese herbal medicine with the actions of replenishing Qi and blood and tonifying liver and kidney, on the endometrial integrin β3 of the mice with embryo implantation dysfunction, and to explore the molecular mechanism of YBR in improving embryo implantation. Methods Ninety mice were divided normal group, model group, and YBR group, 30 mice in each group. YBR group was given Jinghou Zengzhi granules 8mg/kg for promoting post-menstruation proliferation and Cuhuangti granules 8mg/kg for promoting the formation of corpora luteum. At 8∶00 am of pregnant day 4 (Pd4), subcutaneous injection of mifepristone was used for inducing embryo implantation dysfunction in the model group and YBR group. Twenty mice from each group were executed 12 hours after subcutaneous injection of mifepristone, and the uterus was isolated for the detection of mice endometrial integrin β3 mRNA and protein expression with real-time RT-PCR and Western blotting method respectively. Ten mice from each group at Pd4 were executed, and the uterus was isolated and then fixed in 2.5% glutaraldehyde solution for the detection of the formation of pinopode in mice endometrium under scanning electron microscope. Results The detection by real-time PCR and Western blotting method revealed that integrinβ3 mRNA and protein expression levels of the model group were significantly lower than those of the normal group (P<0.05), and YBR group had higher integrin β3 mRNA and protein expression levels than the model group(P<0.05). The formation of pinopodes in the model group was less than the normal group and YBR group, but the number of formed pinopodes in YBR group was similar to that in the normal group. Conclusion YBR can up-regulate the expression of integrin β3 in the endometrium of mice with embryo implantation dysfunction, and have positive regulatory effect on the formation of pinopodes on Pd4.
