Abstract:
OBJECTIVETo investigate the effect of Yangjing Zhongyu Decoction (YJZYD) on expression of insulin-like growth factor II (IGF-II) and its receptor II (IGF-II R) in endometrium of women with unexplained infertility, and the relationship of which with the receptibility of endometrium to ovum implantation.
METHODSReverse transcription-polymerase chain reaction (RT-PCR) assay was used to detect quantitatively the expression of IGF-II and IGF-II R in 22 women with unexplained infertility before and after YJZYD treatment during mid-luteal phase.
RESULTSThe levels of IGF-II and IGF-II R before treatment were 0.794 +/- 0.453 and 0.725 +/- 0.354 (in grey level, the same below) respectively, which were significantly increased in the same phase after treatment, reaching 1.202 +/- 0.551 and 1.045 +/- 0.581 respectively (P < 0.01 and P < 0.05). Correlation analysis showed the level of IGF-II mRNA was positively correlated with the level of IGF-II mRNA either before or after treatment.
CONCLUSIONYJZYD could enhance the expression of IGF-II and IGF-II R in the endometrium during mid-luteal phase, promote the differentiation of endometrium and increase its reception to ovum implantation.
