Methods: Twenty-two infertile women were treated with YZD for 30 days successively. During the mid-luteal phase, in situ hybridization and reverse transcription-polymerase chain reaction method was used to detect MMP-9 and TIMP-1 mRNA, and radioimmunoassay was used to determine levels of serum estradiol (E2) and progesterone (P) synchronously. Results: After treatment, the mid-luteal serum E2 and P level were 451. 501 ± 226. 342 pmol/L and 46. 502 ± 19. 948 nmol/L respectively, significantly higher than that before treatment (304.656 ± 135.853 pmol/L and 33. 782 ± 15. 459 nmol/L respectively) , the difference was significant ( P < 0. 01). Staining of MMP-9 mRNA positive granules in cytoplasm and nuclei of adeno-epithelial cell in mid-luteal phase endometrium deepened significantly, but the change in mesenchym was insignificant. The MMP-9 mRNA expression after treatment was 0.617 ± 0.186 (grey level), significantly higher than the level before treatment (0.490 ± 0. 370), comparison between them showed significant difference ( P < 0. 05 ) . Change of TIMP-1 mRNA expression in adeno-epithelial and mesenchym before and after treatment was insignificant (0. 588 ± 0. 191 vs 0. 621 ± 0. 146,P>0. 05). Correlation analysis showed that the quantitative difference of P level before and after treatment was positively correlated with the difference of MMP-9 mRNA before and after treatment (r=0. 682, P< 0.01). Conclusion: YZD could soothen Gan(肝) and nourish Shen(肾) , raise the level of mid-luteal phase serum P, and further promote MMP-9 gene expression in endometrium to benefit the degradation of extracellular matrix of endometrium, and facilitate for blastocyst implantation.Original article on CJITWM (Chin) 2004 ;24 (4): 294展开更多
