ABSTRACT
Objective To explore the relationship between aryl hydrocar-bon receptor (AhR),aryl hydrocarbon receptor nuclear translocator (ARNT),estradiol (E2),estrogen receptor (ER) and recurrent spontaneous abortion (RSA) through observing the level of serum AhR,ARNT,E2,and AhR,ARNT,ER in decidua and chorionic tissues of the patients with recurrent spontaneous abortion.Methods 64 cases of RSA patients who induced abortion at the Shanxi Dayi hospital from May 2015 to September2017 were chosen as RSA group,and 30 cases of healthy abortion women of the same period who had born full-term normal fetus were choosen as the normal group.The serum,villi and decidua of each case were collected during abortion.The level of AhR,ARNT,ER of both groupswere detected by enzyme-linked immunoscrbent assay (ELISA) method.The Serum E2 lever were detected by the method of chemical luminescence.The data of all the patients were analyzed.Results (1) The level of ARNT in peripheral blood of RSA group was significantly higher than that of normal group (P ＜ 0.05),and the levels of AhR and E2 in peripheral blood were not statistically significant between the two groups (P ＞ 0.05).The levels of AhR and ARNT in villi and decidua were significantly higher in RSA group than in normal group (P ＜ 0.05),while the expression of ER in villi and decidua was significantly lower in RSA group than in normal group (P ＜ 0.05).(2) There was no significant difference in the ratio of AhR/ARNT between the two groups (P ＞ 0.05);the ratio of AhR/ER and ARNT/ER in the villi and decidua of the RSA group was higher than that of the normal group (P ＜ 0.05).Conclusions Overexpression of AhR and ARNT and low expression of ER in villi and decidua tissues may be related to the occurrence of RSA.
ABSTRACT
Objective To explore the correlation between the serum levels of interferon (IFN)-γ,interleukin (IL)-18,IL-10 and recurrent spontaneous abortion (RSA).Methods Enzyme-linked immunosorbent assay was used to detect the serum levels of IFN-γ,IL-18 and IL-10.There were 40 patients with RSA (RSA group) and 40 normal early pregnant women (control group) enrolled in this study.After 2 months,those serum cytokines in two groups of non-pregnant state were detected again.Results Compared to control group,the serum levels of IFN-γ and IL-18 of RSA group were significantly higher (P ＜0.01),the serum level of IL-10 was significantly lower (P ＜ 0.01).Two months after termination of pregnancy,there was no significant difference in the serum levels of IFN-γ and IL-10 between the two groups.The serum level of IL-18 maintained a high level in the RSA group after termination of pregnancy.Conclusions In patients with RSA,the serum levels of IFN-γ and IL-18 were elevated,the serum level of IL-10 was decreased.The serum levels of IFN-γ,IL-18 and IL-10 were closely related with RSA.
