To investigate the effects of ECzhi Tiangui Granule （二至天癸颗粒, ETG） on sequential expressions of integrin β 3 and its ligand osteopontin in the mouse endometrium during controlled ovarian hyperstimulation （COH） and implantation period. Methods： Seventy-five Mature female Kunming mice were randomly divided into 3 groups, a normal control group, a model group, and a treatment group administrated with ETG for 10 days, 25 in each group. After mated with male mice, every 5 mice were sacrified in each group at the 0, 2nd, 4th, 6th, and 8th days to take their endometrium. In-situ hybridization was used to detect the expressions of integrin β 3 and osteopontin in the endometrium. Results： mRNA expressions of integrin β 3 and osteopontin in the endometrium during implantation period showed similar time sequence rules in the treatment group to those in the normal control group; the peak values of them were a little lower in the treatment group than the normal control without significant differences. In the model group, integrin β 3 mRNA expression was higher at the 2nd day, obviously lower at the 4th and 6th days, and insignificantly lower at the 8th day; and osteopontin expression was remarkably lower at the 4th, 6th, and 8th days, compared with the normal control and the treatment groups （P〈0.05, P〈0.01）. Conclusions： COH might influence the sequential expressions of integrin β 3 and its ligand osteopontin, bring forward the integdn β 3 expression peak, impact on the cooperation of integrin β 3 and osteopontin, so as to damage the endometrial receptivity. ETG could regulate the sequential expressions of integrin β 3 and its ligand osteopontin to improve the mouse endometrial receptivity during COH.
