ABSTRACT
The aim of this paper was to investigate the effect of Dingkun Dan on endometrial receptivity in rats with multiple lesions. Forty SD female rats with regular sexual cycle were randomly divided into 5 groups, control group, model group, progynova group, Dingkun Dan group and combination group. The thin endometrium model of kidney-yang deficiency was established in all the other rats except normal control group. The rats in normal control group were free to drink and eat; the rats in the model group were administered with distilled water; the rats in the progynova group were treated with progynova; rats in Dingkun Dan group were treated with Dingkun Dan, and the rats in combination group were treated with Dingkun Dan and progynova. After 15 days, serum levels of OPN, VEGF and MMP-9 were measured by ELISA. HE staining, immunohistochemistry and RT-PCR were used to analyze endome-trial morphology, endometrial thickness and the treatment mechanism of Dingkun Dan. As compared with the control group, the serum levels of OPN, VEGF and MMP-9 in the model group were significantly increased(P<0.01). As compared with the model group, the serum levels of OPN and MMP-9 were decreased in Dingkun Dan group(P<0.05, P<0.01). As compared with the control group, endometrial stromal cells were fewer, the endometrium glands and blood vessels were sparse, and the endometrium was thinner significantly in the model group(P<0.01). As compared with the model group, there were more endometrial glands, rich intimal vessels, and dense stromal cells in various treatment groups, and the endometrium were thickened significantly in the treatment groups(P<0.01). As compared with the control group, the expression area of CK19 in the model group was decreased significantly(P<0.01). As compared with the model group, the expression area of CK19 in each treatment group was increased significantly(P<0.05). As compared with the control group, endometrial β-catenin and MMP-9 mRNA expression levels were increased significantly in the model group(P<0.05), while VEGF mRNA expression was decreased(P<0.05). As compared with the model group, MMP-9 mRNA expression was decreased significantly in the progynova group and the combination group(P<0.05). Dingkun Dan combined with progynova can improve endometrial receptivity by up-regulating expression of β-catenin, VEGF mRNA and down-regulating the expression of MMP-9 mRNA in the injury rats.

This research apply Dingkun Dan to treat patients with dysmenorrhea of cold stagnation and blood stasis syndrome. This study observed its effectiveness and safety of the treatment of the disease and its influence on the serum prostaglandin F2α, endothefin, pulsatility index and resistant index of uterine artery blood, to explore the possible mechanism of effect of Dingkun Dan in the treatment of dysmenorrhea and provide scientific basis for clinical application. The 75 patients with dysmenorrhea of cold stagnation and blood stasis who met the inclusion criteria, were divided into treatment group (n=37) and control group (n=38) by using random number remainder grouping method. In the treatment group patients were treated with Dingkun Dan, the other group were given Fuke Zaizao Jiaonang. Two groups have same time to take the medicine, three days prior to the menstruation for ten days. Medication for three menstrual cycles was seen as a course of treatment. To observe and compare the two groups of patients before and after treatment VAS score, syndrome integral, serum levels of prostaglandin F2α and endothelin, pulsation index and resistance index of uterine artery blood flow and related safety index changes. Finally makes statistical analysis. It has been identified that, Treatment group and control group can reduce pain symptom of dysmenorrhea patients and improve the syndromes scores, compare with control group, effect of the treatment group is more significant(P<0.01). VAS pain curative effect: the treatment group and control group total effective rate respectively were, 97.22%, 69.44%, markedly effective rate were 83.33%, 30.56%, comparison between two groups, treatment group is better than that of control group(P＜0.01). Syndromes curative effect: the treatment group and control group total effective rate respectively were 97.22%, 94.44%, markedly effective rate was 66.67%, 2.78%, respectively. The comparison between two groups, the total effective rate has no obvious difference, but markedly effective rate of treatment group is better than that of control group(P＜0.01). The treatment group can significantly reduce the patients' serum level of prostaglandin F2α(P<0.01), but no obvious difference was found in the control group before and after treatment. Both groups can significantly reduce the serum level of endothelin(P<0.01), comparison between two groups, the treatment group is more significant(P<0.01).Both treatment group and control group were significantly lower left and right pulsation index and resistance index of uterus artery blood flow(P<0.01). Between groups to compare the effect, the treatment group is more significant(P<0.01). Both treatment group and control group in the security check before and after treatment found no significant anomalies. Dingkun Dan in treating dysmenorrhea with cold stagnation and blood stasis syndrome seems to have remarkable clinical curative effect and safety, which may be achieved by significantly reducing the serum level of prostaglandin F2αand endothefin of the patients, and reducing the pulsation index and resistance index of uterine artery blood flow of the patients, to improve uterine artery condition of blood, and correcting local tissue ischemia to relieve pain.
ABSTRACT
The evaluation is based on clomiphene citrate (CC)+gonadotropin (Gn), clinical study on CC and Dingkun Dan's treatment on ovulation induction and clinical pregnancy effect of PCOS, and to provide ideas and methods for traditional Chinese medicine assisted reproductive treatment. This study selected 60 PCOS infertility patients treated with ovulation induction in reproductive medicine clinic, Jiangsu Province Hospital of traditional Chinese medicine during 2015-10-01-2017-04-23. They were randomly divided into two groups： Group A (CC+Gn+HCG) and Group B (CC+Gn+Dingkun Dan). These results were observed and compared including cycle ovulation rate, cycle cancellation rate, cycle pregnancy rate, cumulative pregnancy rate, endometrial thickness, duration of Gn, total amount of Gn, the occurring rate of luteinized unruptured follicle syndrome and ovarian hyperstimulation syndrome. Group A had lower cycle ovulation rate, cycle pregnancy rate, cumulative pregnancy rate and endometrial thickness, compared with Group B, the difference was statistically significant(P＜0.05). However, Group A had higher cycle cancellation rate, duration of Gn and total amount of Gn, compared with Group B, the difference was statistically significant(P＜0.05). In this study, no case of LUFS or OHSS was found in all patients. CC and Dingkun Dan had the effect of promoting ovulation on PCOS infertility patients, and CC+Gn+Dingkun Dan could elevate clinical pregnancy rate.
