Abstract

To observe the effect of acupuncture on CXCL8 receptors (CXCR1 and CXCR2) in rat endometrium experiencing embryo implantation failure, 72 pregnant rats were randomly divided into four groups: normal group (N), embryo implantation failure group (M), acupuncture treatment group (A), and progestin treatment group (W). Then the rats in each group were equally randomized into a day-6 (D6) group, a day-8 (D8) group, and a day-10 (D10) group. The rats in group M, group A, and group W were treated with mifepristone-sesame oil solution on day 1, while the rats in group N were injected with the same amount of sesame oil. Meanwhile, "Housanli" and "Sanyinjiao" were selected for acupuncture. From day 1 to the time of death, the rats in group A were fastened up and then acupuncture was administered while the rats in group N and group M were only fixed, and the rats in group W were given progestin. The number of implanted embryos was calculated. The expression of CXCR1 and CXCR2 in rat endometrium was detected by immunohistochemistry, Western blotting and real-time PCR. Compared to group N, the average number of implanted embryos, the protein and mRNA expression of CXCR1 (D6, D8 and D10), and the protein and mRNA expression of CXCR2 (D8 and D10) in rat endometrium were significantly decreased in group M. Compared to group M, there was significant elevation in the average number of implanted embryos, the protein expression (D6, D8 and D10) and mRNA expression (D8) of CXCR1 in rat endometrium of group A, and the protein expression (D8 and D10) and mRNA expression (D8) of CXCR2 in rat endometrium of group W. These findings indicated that acupuncture can increase the number of implanted embryos in rats of embryo implantation failure, which may be relevant with up-regulation the expression of CXCR1 and CXCR2 at maternal-fetal interface of rats with embryo implantation failure.
