To verify the e ffectiveness of tiaojing decoction on diminished ovarian reserve and uterine artery blood flow parameters, explore the correlation between uterine artery blood flow parameters and sex hormones. Methods: Total 60 diminished ovarian reserve patients with deficiency of Kidney-Yin were randomly divided into the experimental group (n=30, taking tiaojing decoction and climen) and the control group (n=30, taking climen) and they were treated in 3 months. Observe bFSH, bE2, uterine artery PSV, EDV, S/D, RI before and after the treatment in the 2-4 day of menstruation. Results: After treatment, serum sex hormone levels and uterine artery blood flow parameters of the two groups were significantly different (P < 0.05), and the experimental group was significantly better than the control group. There was a linear correlation between PSV and FSH, PSV and E2, FSH and E2. Conclusion: Tiaojing decoction combined with climen has significant effect on diminished ovarian reserve patients with deficiency of Kidney-Yin. Uterine artery blood flow parameters can reflect the sex hormone levels.展开更多

In the present study, we aimed to evaluate the uterine relaxant effect and the influence on uterine artery blood velocity of Ge-Gen Decoction(GGD), a well-known Chinese herbal formula. In female ICR mice, uterine contraction was induced by oxytocin exposure following estradiol benzoate pretreatment, and the uterine artery blood velocity was detected by Doppler ultrasound. Histopathological examination of the uterine tissue samples were performed by H&E staining. Ex vivo studies demonstrated that oxytocin, posterior pituitary, or acetylcholine induced contractions in isolated mouse uterus. GGD inhibited both spontaneous and stimulated contractions. In vivo study demonstrated that GGD significantly reduced oxytocin-induced writhing responses with a maximal inhibition of 87%. Further study demonstrated that GGD normalized oxytocin-induced abnormalities of prostaglandins F_2 alpha(PGF_(2α)) and Ca^(2+) in mice. In addition, injection of oxytocin induced a decrease in uterine artery blood flow velocity. Pretreatment with GGD reversed the oxytocin response on blood flow velocity. Histopathological examination showed pretreatment with GGD alleviated inflammation and edema in the uterus when compared with the model group. Both ex vivo and in vivo results indicated that GGD possessed a significant spasmolytic effect on uterine tetanic contraction as well as improvement on uterine artery blood velocity which may involve PGF_(2α) and Ca^(2+) signaling, suggesting that GGD may have a clinic potential in PD therapy.展开更多
