MEDHODS: The main compounds of BSHXD were determined by high performance liquid chromatographymass spectrometry(HPLC-MS/MS). The effect of BSHXD on Homeobox A10(HOXA10) and alpha(v)beta(3)(αvβ3) integrin expression of Ishikawa cells, mouse model, and endometriosis-associated infertility women was evaluated by using Western blot analysis, immunohistochemistry and Real-Time quantitative polymerase chain reaction(RTq PCR). The efficacy of BSHXD on embryo attachment were examined by using the Be Wo spheroid and mouse embryo attachment assay. HOXA10 concentration in uterine flushing fluid of endometriosis-associated infertility women treated with BSHXD was measured by EnzymeLinked immunosorbent assay(ELISA).RESULTS: BSHXD improved Be Wo spheroid and mice blastocysts attachment to Ishikawa cells and increased embryo implantation rates in mice and pregnancy rates in women with endometriosis-associated infertility. BSHXD enhanced HOXA10 and αvβ3 integrin expression in Ishikawa cell, endometriosis mouse model, and endometriosis-associated infertility women, which potentially improved endometrial receptivity. CONCLUSIONS: BSHXD could improve endometrial receptivity of endometriosis-associated infertility in a dosedependent manner by regulating HOXA10 and αvβ3 integrin expression.展开更多
