RÉSUMÉ
ObjectiveTo explore the clinical efficacy of Dingkundan in the treatment of ovulation disorder infertility based on the real world and provide reliable evidence-based medical support for clinical practice. MethodClinical diagnosis and treatment data of patients with ovulation disorder infertility in the real world were collected through the Medroad Cloud system. Patients were grouped according to their real-world treatments， and the total effective rate， ovulation rate per cycle， number of days of follicle development， gonadotropin （Gn） dosage， levels of mature follicle-related hormones， endometrial thickness and classification， pregnancy rate per cycle， clinical pregnancy rate， ectopic pregnancy rate， and early pregnancy loss rate were observed. ResultA total of 207 patients were included， and the most common traditional Chinese medicine （TCM） syndrome in the entire population was liver depression and kidney deficiency. The patients were divided into a Chinese medicine group （Dingkundan， 60 cases）， a western medicine group （ovulation induction， 51 cases）， and a combination group （Dingkundan + ovulation induction， 96 cases）. The combination group（98.96%，95/96） had the highest total effective rate， which was statistically significant when compared with the Chinese medicine group（88.33%，53/60） （χ2=8.328， P<0.05）. The mature follicle estradiol （E2） and luteinizing hormone （LH） levels were the highest in the combination group， and there were statistically significant differences when compared with the western medicine group （P<0.01）. The endometrial thickness was higher in the Chinese medicine group and the combination group than in the western medicine group （P<0.01）. The proportion of type A endometrium was highest in the combination group（85.90%，201/234）， and there was a statistically significant difference when compared with the western medicine group（73.81%，93/126） （χ2=7.993， P<0.01）. The clinical pregnancy rate was 60.42%（58/96） in the combination group， which was higher than 36.67%（22/60） in the Chinese medicine group （χ2=8.336， P<0.01） and 39.22%（20/51） in the western medicine group （χ2=6.011， P<0.05）. Compared with the western medicine group， the combination group showed a favorable trend in total effective rate， ovulation rate per cycle， number of days of follicle development， Gn dosage， pregnancy rate per cycle， ectopic pregnancy rate， and early pregnancy loss rate， but the differences were not statistically significant. ConclusionIn real-world clinical practice， the combination of Dingkundan with ovulation induction can increase endometrial thickness， improve the proportion of type A endometrium， enhance egg quality， and increase the clinical pregnancy rate in patients with ovulation disorder infertility. This approach deserves further clinical research and application.
RÉSUMÉ
Objective To study the anti-aging effect of total saponins of Polygala tenuifolia (PTS). Methods The effects of total saponins of Polygala tenuifolia on oxygen free radicals were investigated by the methods of scavenging hydroxyl radical, superoxide radical and DPPH oxygen free radicals in vitro. The photoaging model of mice skin was established to observe the effect of total saponins of Polygala tenuifolia on mouse skin pathology. Results In the experiment of antioxidation in vitro, the total saponins of Polygala tenuiflora significantly scavenged hydroxyl free radicals (P<0.05, P<0.001) and superoxide radical (P<0.01) at 6.0 and 12.0mg/mL, DPPH free radicals (P<0.001). In the light aging experiment, the light aging model of mice skin was established successfully in group B (model + medium tea oil). Compared with group B, the density of the skin epidermis in D group (30 min before irradiation, 6mg/mL PTS) was thickened, the elastic fibers were arranged uniformly and tightly, the collagen fibers proliferated significantly and densely, and the inflammatory cells infiltration was not found. The treatment effect was most remarkable in group G (30min after irradiation, PTS 12mg/mL PTS), and the skin of the mice was thickened, the elastic fibers were evenly arranged, the collagen fibers had some hyperplasia, evenly distributed, and there was no infiltration of inflammatory cells, which had significant therapeutic effect. Conclusion The total saponins of Polygala tenuifoliahas significant antioxidant activity and anti - light aging effect.

Salmonella is a pathogenic bacteria to human and animals ,which can cause seriously complication and death . Salmonella pathogenicity is from the reactions of SP‐1 and SP‐2 T3SS effector proteins .In this paper ,the functions of different T3ss effector proteins in different infection periods is reviewed to provide a reference for further understanding the pathogenesis mechanisms of Salmonella .
