Abstract:
Objective To explore the effects of Peiyuan Yishen Antai Decoction on cell senescence and decidualization of aged mice with recurrent spontaneous abortion(RSA)based on P53/P21 signaling pathway;To discuss its mechanism in the treatment of RSA.Methods 8-9 month old CBA/J female mice were randomly divided into aging model group(normal saline 0.3 mL/d),Chinese materia medica group(18.72 g/kg)and dydrogesterone group(2.6 mg/kg).6-8 week old CBA/J female mice were assigned to a reproductive age blank group(normal saline 0.3 mL/d),with five mice in each group.After administering the corresponding solutions by gavage for 2 weeks,the reproductive age blank group mice were housed in cages with BALB/c male mice,while the remaining groups were housed in cages with DBA/2 male mice.After confirming the presence of vaginal plug,gavage was continued until the 9th day of pregnancy for sampling.Mice embryo loss rate was observed,HE staining was used to observe the morphology of uterine decidua,immunohistochemistry was used to detect the localization and expression of aging related protein Pi6INK4a in decidua tissue,RT-PCR and Western blot were used to detect the mRNA and protein expressions of P53,P21,insulin-like growth factor binding protein 1(IGFBP-1)and prolactin(PRL)in decidual tissue.Results Compared with the reproductive age blank group,the embryo loss rate of the aging model group significantly increased(P＜0.05),the irregular endometrial cells were vacuolated,the number of glands and blood vessels was reduced,the expression of P16INK4a in decidual tissue significantly increased(P＜0.05),and the expressions of P53,P21 mRNA and protein significantly increased(P＜0.05),the mRNA and protein expressions of IGFBP-1 and PRL significantly decreased(P＜0.05).Compared with the aging model group,the Chinese materia medica group and the dydrogesterone group showed an decreasing trend in embryo loss rate in mice,the arrangement of cells in the decidua tissue was relatively neat,and the number of blood vessels and glands increased,the expression of P16INK4a in decidua tissue was significantly decreased(P＜0.05),the mRNA and protein expressions of P53 and P21 were significantly decreased(P＜0.05),while the mRNA and protein expressions of IGFBP-1 and PRL significantly increased(P＜0.05).Conclusion Peiyuan Yishen Antai Decoction can improve the aging status of endometrial stromal cells in aged RSA model mice by regulating the P53/P21 signaling pathway,promote decidualization process,and thus exert a protective effect on pregnancy.
