Effects of Jiawei Buzhong Yiqi Decoction on the Endometrial Receptivity of Rats with Polycystic Ovary Syndrome

[Objectives]The study aims to discuss the effects of Jiawei Buzhong Yiqi Decoction on the endometrial receptivity of rats with polycystic ovarian syndrome(PCOS).[Methods]Adult female SD rats were selected and randomly divided into the model group and control group.In the model group,the PCOS model was established by using the method of Poretsky L.Rats in the control group were given physiological saline intervention at the same time.The successfully modeled rats were randomly divided into the PCOS group and traditional Chinese medicine group.Among them,rats in the Chinese medicine group were given Jiawei Buzhong Yiqi Decoction by gavage;rats in the model group and the control group were given normal saline for 14 d.All rats were killed by anesthesia after the last administration,and serum and uterine specimens were collected.Serum sex hormones(including T,E_(2),and P),glucose and insulin levels were detected;the equivalent diameter and area of endometrial gland and gland cavity,and the endometrial thickness of rats were measured;the expression of endometrial leukemia inhibitory factor(LIF),integrinαvβ3 protein and mRNA was detected by using Elisa and RT-PCR methods.[Results]The serum T,glucose,and insulin levels of rats in the PCOS group were significantly higher than those of the control group and the traditional Chinese medicine group,and there was no significant difference in the above indicators between the control group and the traditional Chinese medicine group;there was no significant difference in the E_(2) and P levels between the three groups.The equivalent diameter and area of endometrial gland and gland cavity,and the endometrial thickness of rats in the PCOS group were lower than those of the control group and the traditional Chinese medicine group;there was no significant difference in the above indicators between the traditional Chinese medicine group and the control group.The expression of LIF,integrinαvβ3 protein and mRNA in the endometrium of rats in various groups was basically the same.The expression of LIF and integrinαvβ3 in the endometrium of rats in the PCOS group was significantly lower than that of the control group and the traditional Chinese medicine group;there was no significant difference in the above indicators between the control group and the traditional Chinese medicine group.[Conclusions]The endometrial receptivity of PCOS rats was decreased;Jiawei Buzhong Yiqi Decoction can improve the endometrial receptivity of PCOS rats by increasing the expression of LIF and integrinαvβ3 in the endometrium.
