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

Methods: SRs of randomized controlled trials(RCTs) on TG or TGP in treating RA were included, by searching 8 databases from their inception until December 2017. Two authors extracted data independently. We assessed the quality of SRs using AMSTAR and graded the quality of evidence according to the GRADE approach. Results: Eleven SRs containing an average of 7.6 RCTs, involving a total of 7,012 participants were included in this overview. On the basis of included SRs, TG and TGP could improve the following indexes for RA patients: American College of Rheumatology(ACR) 20 response rate, ACR50 response rate and ACR70 response rate, swollen joint count, tender joint count, erythrocyte sedimentation rate and C-reactive protein. Moreover, TGP could reduce incidence of hepatotoxicity. The most common adverse effects of TG were gastrointestinal discomfort and gonad toxicity, while for TGP was mild to moderate diarrhea. The overall quality of evidence for these findings ranged from "low" to "moderate". Conclusions: TG and TGP might be 2 potentially effective complementary and alternative drugs for patients with RA. Nevertheless, due to gonad toxicity, TG should only be considered in elderly patients or patients without reproductive needs. More evidence from high quality RCTs and SRs is warranted to support the use of TG and TGP for RA patients.展开更多

The present study aimed to evaluate the effectiveness and safety of adding TGs to angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs).Methods::By searching Embase, MEDLINE, Cochrane Library, SINOMED, China National Knowledge Infrastructure, VIP Information/Chinese Scientific Journals, and WANFANG databases, we identified previous studies that met the specific selection criteria and included them in the meta-analysis. Analyses were performed using Review Manager (version 5.3).Results::Nine randomized controlled trials were included in the final meta-analysis. Patients were compared before and after treatment with ACE inhibitors or ARBs plus TGs, or ACE inhibitors or ARBs alone. The results revealed that treatment with ACE inhibitors or ARBs plus TGs resulted in significantly greater reductions in 24-h urinary total protein (UTP) levels (trial duration <2 months, mean difference [MD]: -0.25;95% confidence interval [ CI]: -0.32, -0.18;trial duration between 2 and 6 months, MD: -0.39;95% CI: -0.44, -0.33;trial duration >6 months, MD: -2.09;95% CI: -2.89, -1.29) compared with treatment using ACE inhibitors or ARBs alone. Additionally, ACE inhibitors or ARBs plus TGs showed better results after longterm administration. Treatment with ACE inhibitors or ARBs plus TGs resulted in significantly greater reductions in serum creatinine (SCr) compared with ACE inhibitors or ARBs alone (MD: -9.87;95% CI: -13.76, -5.97). Conclusion::In patients with DN, adding TGs to ACE inhibitors or ARBs significantly lowered both the 24-h UTP and SCr levels. Therefore, ACE inhibitors or ARBs plus TGs might improve the treatment of DN in patients.展开更多

Data of the included studies were extracted and analyzed independently by two authors, and were synthesized using Review Manager(version 5.2) and Stata(version 12.0).Results: A total of 12 randomized controlled trials(RCTs) involving 829 patients were included. Pooled results showed that the combination therapy significantly increased total efficacy of DN patients [RR = 1.35,95% CI(1.22, 1.50), P < 0.001], the level of serum albumin [Mean difference(MD)= 3.87, 95% CI(3.12,4.62), P < 0.001], and significantly decreased 24 h urinary protein level [MD =-0.97, 95% CI(-1.19,-0.76), P < 0.001], urinary albumin-excretion rate [MD =-145.53, 95% CI(-227.95,-63.11), P < 0.001],and urinary β2-microglobuli level [MD =-11.86, 95% CI(-13.02,-10.69), P < 0.001]. No significant differences were found in levels of serum creatinine [MD =-0.26, 95% CI(-7.52, 7.00), P > 0.05), blood urea nitrogen [MD = 0.25, 95% CI(-0.23, 0.74), P > 0.05], and endogenous creatinine clearance rate[MD =-0.43, 95% CI(-3.48, 2.62), P > 0.05]. However, tripterygium glycosides plus valsartan seemed to exert higher adverse reaction rate than valsartan monotherapy [MD = 3.41, 95% CI(1.34, 8.66), P < 0.05].There were no publication bias for all of the pooled effect sizes.Conclusion: Combination therapy of tripterygium glycosides plus valsartan may be effective for the treatment of DN. However, the safety of the combination therapy need to be further confirmed.展开更多

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 leiomyoma 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. O1 ) as compared with pretreatment values, hi 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

Methods: Sixty old patients with RA were equally divided into two groups, the treated group was treated with oral intake of TP (10 mg three times per day) plus MTX (7. 5 mg, once per week), and the control group was treated with MTX (15 mg per week) respectively for 3 months. The changes from before to after treatment in resting pain, morning rigidity, bilateral grip strength, local tenderness index, arthroncus index, patient's evaluation, doctor's evaluation, erythrocyte sedimentation rate (ESR), C-reaction protein (CRP) and rheumatoid factor(RF) titre were observed and the clinical therapeutic effect assessed. Results: The total effective rate in the treated group was 86.67% and that in the control group 83.33%, showing insignificant difference between them ( P＞0.05). But the improvement in local tenderness index, arthroncus index, morning rigidity and ESR in the treated group was significantly better than those in the control group (P＜0.01 or P＜0.05).The occurrence rate of adverse reaction in the treated group was 26.67 %, which was lower than that in the control group (43.33%), showing significant difference (P＜0.01). Conclusion: TP combined with small dose of MTX is a favorable therapeutic method for treating senile RA.展开更多

We aimed to investigate the protective effects of C. daurica extracts and phenylethanoid glycosides including verbascoside and isoacteoside on INS-1 cells. We discovered phenylethanoid glycosides from n-butanol extract with large content through extraction and separation. We continue to study the protective effects of phenylethanoid glycosides including verbascoside and isoacteoside on INS-1 cells. INS-1 cells were treated with C. daurica, cell viability assay, RNA-seq technology, superoxide dismutase activity and malonaldehyde content, quantitative real time-PCR and Western blot analysis were used to study the protective effects of C. daurica. Cell viability assay resulted that n-butanol extract and verbascoside, isoacteoside showed protective effects of C. daurica. According to the RNA-seq technology to identify the differentially expressed genes in INS-1 cells, the pathway of gene enrich the protective effect of C. daurica on oxidative stress.

文摘Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40%of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated hepatic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and therapeutic targets for liver protection.

文摘The traditional Chinese medicine tripterygium glycosides(TPG)is used clinically to treat some Rheumatism,Eczema,immunosuppression and tumor,with the activities of hypnosis,antipyretic,analgesic,antiinflammatory,allergy and antitumor.However TPG has low water solubility and low skin permeability,so its clinical use is limited.Transdermal delivery systems can provide a controlled drug release rate that can keep constant concentrations of drug in the plasma for up to multiple days,improved patient compliance,and the possibility ofreducing the rate and severity of side effects.In this study,a fast and sensitive technique skin-blood two sites synchronous microdialysis coupled with LC-MS was used to study the pharmacokinetic parameter of three different formulations(TPG nanoemulsion,TPG nanoemulsion based gels and TPG gel).Creating a multilayer model,use the model to simulate the three formulations dynamics in transdermal-drug delivery system.The experiment results showed that the TPG nanoemulsion,TPG nanoemulsion based gels can significantly raise the drug concentrations in skin more than that of TPG gels.The numerical simulation results indicating that TPG gel and TPG nanoemulsion are close to practical measurements,only in the concentration increase phase the numerical simulation result has some difference with the experimental results.TPG nanoemulsion based gels have significant difference with the experimental results,both in concentration increase stage and concentration decreasing stage,but its trend was same.The study shows that the skin-blood synchronous microdialysis technique provided a new method for the pharmacokinetics study of nanocarriers transdermal delivery systems.In addition,the microdialysis technique combined with mathematical modeling provides a very good platform for the further study of transdermal delivery system.

文摘Objectives:To explore and summarize the beneficial effects of a traditional Chinese medicine preparation,Tripterygium glycosides tablets(TGT),in rheumatoid arthritis(RA)animal models of neovascularization,and to provide a reference for future clinical applications and research on its pharmacologic mechanism.Methods:We searched the databases PubMed,Embase,Web of Science,Chinese National Knowledge Infrastructure,VIP,Wan Fang and SinoMed(China Biomedical Document Service System)to identify studies of TGT with outcome indicators of angiogenesis-related factors that were published before April2020.Subgroup analysis and meta-regression were performed for dosage and duration of TGT.Statistical tests and subgroup analysis were conducted using RevMan 5.3,and meta-regression and sensitivity analysis were conducted using STATA/SE 15.0.Results:Fourteen studies of TGT in RA rats were included in this analysis.Treatment with TGT significantly reduces synovial microvessel density and the expression of vascular endothelial growth factor(VEGF),VEGF receptor 2,hypoxia inducible factor a,c-Fos,c-Jun,angiopoietin-1 and angiopoietin-2 compared with control groups(P<.05).Subgroup analysis did not show a significant association of the mRNA levels of VEGF in synovium,assessed using quantitative real-time PCR,with duration or dosage of TGT.Meta-regression analysis also indicated that the effects of dosage and duration were not significantly associated with differences in VEGF mRNA levels.Sensitivity analysis on VEGF m RNA levels did not fundamentally change the results.Conclusions:TGT can reduce synovial neovascularization by decreasing synovial microvessel density and expression of VEGF,VEGF receptor 2,hypoxia-inducible factor a,c-Fos,c-Jun,Ang-1 and Ang-2,thereby suppressing pannus formation and bone destruction in rat models of RA.Additional well-designed studies are required to confirm these findings.

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).
文摘Objective: To compare the therapeutic effects of Radix Tripterygium hypoglaucum tablet (THT) and Tripterygium glycosides tablet (TGT) in treating erosive oral lichen planus(EOLP).Methods: The patients were randomized into two groups, and they were treated with THT (n=47) or TGT (n=47), respectively. 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.

文摘Objective: To summarize the evidence from systematic reviews(SRs) on the benefits and safety of Tripterygium glycosides(TG) and total glucosides of paeony(TGP), commonly used to treat rheumatoid arthritis(RA) in China, for patients with RA. Methods: SRs of randomized controlled trials(RCTs) on TG or TGP in treating RA were included, by searching 8 databases from their inception until December 2017. Two authors extracted data independently. We assessed the quality of SRs using AMSTAR and graded the quality of evidence according to the GRADE approach. Results: Eleven SRs containing an average of 7.6 RCTs, involving a total of 7,012 participants were included in this overview. On the basis of included SRs, TG and TGP could improve the following indexes for RA patients: American College of Rheumatology(ACR) 20 response rate, ACR50 response rate and ACR70 response rate, swollen joint count, tender joint count, erythrocyte sedimentation rate and C-reactive protein. Moreover, TGP could reduce incidence of hepatotoxicity. The most common adverse effects of TG were gastrointestinal discomfort and gonad toxicity, while for TGP was mild to moderate diarrhea. The overall quality of evidence for these findings ranged from "low" to "moderate". Conclusions: TG and TGP might be 2 potentially effective complementary and alternative drugs for patients with RA. Nevertheless, due to gonad toxicity, TG should only be considered in elderly patients or patients without reproductive needs. More evidence from high quality RCTs and SRs is warranted to support the use of TG and TGP for RA patients.

文摘Introduction::Tripterygium glycosides (TGs) have been widely used in China to treat diabetic nephropathy (DN);however, proof of their use is scarce. The present study aimed to evaluate the effectiveness and safety of adding TGs to angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs).Methods::By searching Embase, MEDLINE, Cochrane Library, SINOMED, China National Knowledge Infrastructure, VIP Information/Chinese Scientific Journals, and WANFANG databases, we identified previous studies that met the specific selection criteria and included them in the meta-analysis. Analyses were performed using Review Manager (version 5.3).Results::Nine randomized controlled trials were included in the final meta-analysis. Patients were compared before and after treatment with ACE inhibitors or ARBs plus TGs, or ACE inhibitors or ARBs alone. The results revealed that treatment with ACE inhibitors or ARBs plus TGs resulted in significantly greater reductions in 24-h urinary total protein (UTP) levels (trial duration <2 months, mean difference [MD]: -0.25;95% confidence interval [ CI]: -0.32, -0.18;trial duration between 2 and 6 months, MD: -0.39;95% CI: -0.44, -0.33;trial duration >6 months, MD: -2.09;95% CI: -2.89, -1.29) compared with treatment using ACE inhibitors or ARBs alone. Additionally, ACE inhibitors or ARBs plus TGs showed better results after longterm administration. Treatment with ACE inhibitors or ARBs plus TGs resulted in significantly greater reductions in serum creatinine (SCr) compared with ACE inhibitors or ARBs alone (MD: -9.87;95% CI: -13.76, -5.97). Conclusion::In patients with DN, adding TGs to ACE inhibitors or ARBs significantly lowered both the 24-h UTP and SCr levels. Therefore, ACE inhibitors or ARBs plus TGs might improve the treatment of DN in patients.

文摘Objective: To assess the efficacy and safety of the combination therapy of Chinese herbal medicines,tripterygium glycosides, plus valsartan for the treatment of diabetic nephropathy(DN).Methods: A comprehensive research of 12 electronic databases was performed. Data of the included studies were extracted and analyzed independently by two authors, and were synthesized using Review Manager(version 5.2) and Stata(version 12.0).Results: A total of 12 randomized controlled trials(RCTs) involving 829 patients were included. Pooled results showed that the combination therapy significantly increased total efficacy of DN patients [RR = 1.35,95% CI(1.22, 1.50), P < 0.001], the level of serum albumin [Mean difference(MD)= 3.87, 95% CI(3.12,4.62), P < 0.001], and significantly decreased 24 h urinary protein level [MD =-0.97, 95% CI(-1.19,-0.76), P < 0.001], urinary albumin-excretion rate [MD =-145.53, 95% CI(-227.95,-63.11), P < 0.001],and urinary β2-microglobuli level [MD =-11.86, 95% CI(-13.02,-10.69), P < 0.001]. No significant differences were found in levels of serum creatinine [MD =-0.26, 95% CI(-7.52, 7.00), P > 0.05), blood urea nitrogen [MD = 0.25, 95% CI(-0.23, 0.74), P > 0.05], and endogenous creatinine clearance rate[MD =-0.43, 95% CI(-3.48, 2.62), P > 0.05]. However, tripterygium glycosides plus valsartan seemed to exert higher adverse reaction rate than valsartan monotherapy [MD = 3.41, 95% CI(1.34, 8.66), P < 0.05].There were no publication bias for all of the pooled effect sizes.Conclusion: Combination therapy of tripterygium glycosides plus valsartan may be effective for the treatment of DN. However, the safety of the combination therapy need to be further confirmed.

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 leiomyoma 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. O1 ) as compared with pretreatment values, hi 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 observe the effect and adverse reaction of tripterygium polyglycosides (TP) combined with small dose of methotrexate (MTX) in treating senile rheumatoid arthritis (RA). Methods: Sixty old patients with RA were equally divided into two groups, the treated group was treated with oral intake of TP (10 mg three times per day) plus MTX (7. 5 mg, once per week), and the control group was treated with MTX (15 mg per week) respectively for 3 months. The changes from before to after treatment in resting pain, morning rigidity, bilateral grip strength, local tenderness index, arthroncus index, patient's evaluation, doctor's evaluation, erythrocyte sedimentation rate (ESR), C-reaction protein (CRP) and rheumatoid factor(RF) titre were observed and the clinical therapeutic effect assessed. Results: The total effective rate in the treated group was 86.67% and that in the control group 83.33%, showing insignificant difference between them ( P＞0.05). But the improvement in local tenderness index, arthroncus index, morning rigidity and ESR in the treated group was significantly better than those in the control group (P＜0.01 or P＜0.05).The occurrence rate of adverse reaction in the treated group was 26.67 %, which was lower than that in the control group (43.33%), showing significant difference (P＜0.01). Conclusion: TP combined with small dose of MTX is a favorable therapeutic method for treating senile RA.

文摘Cymbaria daurica L. is a well-known traditional Mongolian medicine, which has been used to treat diabetesrelated conditions characterized by persistent thirst and hunger, copious urination, and weight loss. We aimed to investigate the protective effects of C. daurica extracts and phenylethanoid glycosides including verbascoside and isoacteoside on INS-1 cells. We discovered phenylethanoid glycosides from n-butanol extract with large content through extraction and separation. We continue to study the protective effects of phenylethanoid glycosides including verbascoside and isoacteoside on INS-1 cells. INS-1 cells were treated with C. daurica, cell viability assay, RNA-seq technology, superoxide dismutase activity and malonaldehyde content, quantitative real time-PCR and Western blot analysis were used to study the protective effects of C. daurica. Cell viability assay resulted that n-butanol extract and verbascoside, isoacteoside showed protective effects of C. daurica. According to the RNA-seq technology to identify the differentially expressed genes in INS-1 cells, the pathway of gene enrich the protective effect of C. daurica on oxidative stress. SOD activity and the content of MDA indicated that C. daurica could enhance the antioxidant capacity of INS-1 cells. Further investigation indicated C. daurica alleviate oxidative stress by inhibiting INS-1 cell apoptosis. C. daurica may play an anti-diabetic role by inhibiting islet cell apoptosis.
