The therapeutic effects were evaluated after 3 months treatment.Results: For the patients of grade 1, the total efficacy in TGT group was 85.71%, compared with 52.38% in THT group, the efficacy was statistically greater in the group receiving TGT (P=0.043). However, for the patients of grade 2, the difference was not statistically significant (P=0.173).Conclusion: TGT is more effective in treating EOLP than THT for grade 1 patients. However, TGT is not suitable for patients of child bearing age.展开更多

( GTW) glycosides on patients with uterine leiomyomas. Methods 65 normally cycling women with symptomatic uterine leiomyomas received 40mg daily dose GTW for 3 to 6 months. Baseline ultrasound tests were obtained to evaluate the sizes of myomas and uterus, then repeated three and six months after treatment. Blood samples were collected to determine the hormonal levels of in the mid-follicular and mid-luteal phases of the menstrual cycles before GTW therapy and at 3~4 months and 5~6 months after treatment. Results Significant decrease in leiomy-oma volume was shown in 39 of 65 (60% ) and 28 of 40 ( 70% ) patients after 3~4 months and 5~6 months of treatment, respectively. The decrease of the volume of leiomyoma was time-dependent as while 27. 84% and 51.60% in 3~4 months and 5 ~ 6months, respectively. 25 of 65 patients had amenorrhea during the course of treatment. Tripterygium wilfordii glycosides treatment induced a significant increase in LH and FSH levels (P < 0. 01) as compared with pretreatment values. In contrary, a significant decrease in E2 and P levels (P <0. 05) was found, but no changes were observed in T and PRL levels after treatment. Conclusion Tripterygium wilfordii might serve as an effective therapeutic agent for leiomyomas with fewer side effects. A reversible inhibitory effect on the ovary by Tripterygium wilfordii glycosides may be one of the mechanisms of Tripterygium wilfordii in decreasing leiomyoma volume.展开更多

文摘Background:Diabetic kidney disease is now the principal cause of end-stage renal failure worldwide.Alprostadil combined with tripterygium glycosides tablet is a new method for diabetic kidney disease treatment.However,there are currently few systematic reviews on treatment for alprostadil combined with tripterygium glycosides tablet.Therefore,a systematic review and meta-analysis was conducted to analyze the function of alprostadil combined with tripterygium glycosides tablet in the treatment of diabetic kidney disease.Methods:We searched Pubmed,Embase,the Cochrane Library,Chinese databases,and clinical trial for randomized controlled trials of alprostadil combined with tripterygium glycosides tablet in the treatment of diabetic kidney disease,including results from the foundation of database until August 5,2020.Two reviewers have independently performed literature screening,data extraction,and quality evaluation.This meta-analysis has been carried out by RevMan5.4 software.Results:Ten randomized controlled trials with 724 patients were involved.Compared with alprostadil alone,the combination of alprostadil and tripterygium glycosides tablet in treatment of diabetic kidney disease could reduce the level of 24-hour urine protein(95%CI(–2.05,–0.22),P=0.01),serum creatinine(95%CI(–5.01,–0.20),P=0.03),level of interleukin-6(95%CI(−4.57,−2.37),P<0.00001),tumor necrosis factor-α(95%CI(−4.57,−2.37),P<0.00001).The combined treatment could also improve the clinical efficacy(95%CI(1.09,1.25),P<0.0001),and reduce the occurrence of serious adverse events(95%CI(0.26,0.94),P=0.03).However,there is no association of two treatments in blood urea nitrogen(95%CI(–4.17,2.11),P=0.52),albumin(95%CI(–1.10,0.97),P=0.90),triglyceride(95%CI(−1.44,1.50),P=0.97).Conclusion:Alprostadil combined with tripterygium glycosides tablet contributes to protecting renal function,inhibiting inflammation,and reducing the occurrence of adverse events,which could be considered as a feasible therapy for diabetic kidney disease patients.However,some clinical variables did not accurately conclude due to the low quality of methodology and small sample sizes.More rigorous and more extensive trials are essential to validate our results.Trial registration:Systematic review registration:(CRD42020203725).

Results Significant decrease in leiomy-oma volume was shown in 39 of 65 (60% ) and 28 of 40 ( 70% ) patients after 3~4 months and 5~6 months of treatment, respectively. The decrease of the volume of leiomyoma was time-dependent as while 27. 84% and 51.60% in 3~4 months and 5 ~ 6months, respectively. 25 of 65 patients had amenorrhea during the course of treatment. Tripterygium wilfordii glycosides treatment induced a significant increase in LH and FSH levels (P < 0. 01) as compared with pretreatment values. In contrary, a significant decrease in E2 and P levels (P <0. 05) was found, but no changes were observed in T and PRL levels after treatment. Conclusion Tripterygium wilfordii might serve as an effective therapeutic agent for leiomyomas with fewer side effects. A reversible inhibitory effect on the ovary by Tripterygium wilfordii glycosides may be one of the mechanisms of Tripterygium wilfordii in decreasing leiomyoma volume.

文摘Objective To determine the possible protective effects of Jinghuosu,a dietary supplement(DS),on tripterygium glycosides(TG)-induced reproductive system injury in rats and its underlying mechanisms.Methods A reproductive damage model was established in rats by feeding of TGs.Twenty-eight male Sprague Dawley rats were randomly divided into 4 groups using a random number table(n=7 in each):control(C)group,model(M)group,DS group and L-carnitine(LC)group.Rats in M,DS and LC groups received 40 mg/kg TGs orally.Starting from the 5th week,after administration of TGs for 4 h every day,rats in DS and LC groups were administered with 2.7 g/kg DS and 0.21 g/kg LC,respectively,for protective treatment over the next 4 weeks.Rats in Group C continued to receive the control treatment.Hematoxylin-eosin staining was used for histopathological analysis of rat testicular tissues.Enzyme-linked immunosorbent assay was performed to measure alkaline phosphatase(ALP),lactate dehydrogenase,alcohol dehydrogenase,total antioxidant capacity(T-AOC),superoxide dismutase,glutathione peroxidase(GSH-Px),and malondialdehyde(MDA)concentrations.Chemiluminescence assay was used to determine the serum testosterone content.Quantitative real-time PCR and Western blotting were conducted to analyze the expression of genes and proteins related to the testosterone synthesis pathway and the nuclear factor erythroid 2-related factor 2/heme oxygenase 1 antioxidant pathway.Results Oral administration of TGs induced significant increases in the testicular levels of zinc transporter 1 and MDA(P<0.05).On the other hand,sperm concentration,sperm motility,and serum testosterone,serum zinc,testicular zinc,Zrt-,Irt-like protein 1,ALP,luteinizing hormone(LH)receptor,steroidogenic acute regulatory protein,Cytochrome P450 family 11 subfamily A member 1,3β-hydroxysteroid dehydrogenase 1 T-AOC,GSH-Px,nuclear factor erythroid 2-related factor 2,heme oxygenase-1 and NAD(P)H:quinone oxidoreductase 1 levels decreased following TGs exposure(P<0.05).All of these phenotypes were evidently reversed by DS(P<0.05).Conclusion DS Jinghuosu protects against TG-induced reproductive system injury in rats,probably by improving zinc homeostasis,enhancing the testosterone synthesis and attenuating oxidative stress.
