Mice were randomly divided into five groups, including the normal （N）, model （M）, Bushen （BS）, Huoxue （HX） and Bu-Shen-An-Tai （BH） groups. The uteri were collected on day 4 of pregnancy, and the endometrium thickness, microvessel density （MVD） and number of pinopodes observed. Compared with the M group, the endometrial thickness in the BS, HX and BH groups was significantly increased and there was a significant difference in endometrial thickness between the BS and the BH groups. The mean MVD was significantly lower in the M group than in the N group, and there was a significant increase in MVD in the BS, HX and BH groups as compared with the M group. Compared with the M group, the pinopode scores in the en- dometrium were significantly increased in the HX and BH groups; and the BS group had significantly higher pinipode scores than the HX and BH groups. In conclusion, the results of the present study demonstrated that the recipes （Bushen, Huoxue and BSATR） could improve the endometrial envi- ronment by regulating the endometrial thickness, MVD and the number of pinopodes at the window of implantation. Moreover, the Huoxue recipe and the BSATR were more efficient than the Bushen recipe, with the BSATR tending to have the most beneficial effects.展开更多
