Abstract:
Objective To observe the effects of Bushen Antai Mixture on vascular recasting at the maternal-fetal interface in mice with recurrent spontaneous abortion(RSA)based on AMPK/ULK1/Beclin1 pathway.Methods CBA/J female mice and BALB/c male mice were caged at a ratio of 2:1 to establish normal pregnant mice(normal group),and CBA/J female mice and DBA/2 male mice were caged to establish RSA model.The RSA mice were randomly divided into model group,autophagy agonist group and TCM high-,medium-and low-dosage groups,with 10 mice in each group.From the first day of pregnancy,TCM high-,medium-and low-dosage groups were given Bushen Antai Mixture 35.1,11.7 and 3.9 g/kg by gavage respectively,and the normal group,model group and autophagy agonist group were given the same amount of normal saline by gavage for 15 days.The embryo development was observed and the embryo loss rate was calculated,the morphology of decidual tissue was observed by HE staining;the contents of vascular endothelial growth factor(VEGF)and vascular endothelial cadherin(VE-cadherin)in decidual tissue were detected by ELISA;the expressions of autophagy related proteins adenosine monophosphate-activated protein kinase(AMPK),UNC-51 like kinase 1(ULK1),Beclin1 and LC3B in decidual tissue were detected by Western blot.Results Compared with the normal group,the embryo loss rate of mice in the model group significant increased(P<0.01),the cells of the decidual tissue were disordered,the interstitium was edematous,the nuclei disappeared,there were a large number of inflammatory cells infiltration,the number of blood vessels was reduced,the contents of VEGF and VE-cadherin in decidual tissue significantly decreased(P<0.01),and the protein expressions of AMPK,ULK1,Beclin1,LC3BⅡ/LC3BⅠ significantly decreased(P<0.01).Compared with the model group,the embryo loss rate of mice in TCM high-,medium-and low-dosage groups and autophagy agonist group showed a significant downward trend(P<0.05),and the cells of decidual tissue were aligned,the interstitium edema was reduced,the nuclei of the cells increased,the inflammatory cells infiltration were reduced and the number of blood vessels increased,the contents of VEGF and VE-cadherin in decidual tissue significantly increased in TCM high-,medium-dosage groups and autophagy agonist group(P<0.05),and the protein expressions of AMPK,ULK1,Beclin1 and LC3BⅡ/LC3BⅠ significantly increased(P<0.01).Conclusion Bushen Antai Mixture may promote the recasting of blood vessels at the maternal-fetal interface by activating AMPK/ULK1/Beclin1 pathway,improve the pregnancy survival rate of RSA mice,and play a role in the treatment of RSA.
