Effects of intranasal administration of tripterygium glycoside-bearing liposomes on behavioral cognitive impairment of mice induced by central nervous system inflammation / 中国中药杂志

Tripterygium glycosides liposome(TPGL) were prepared by thin film-dispersion method, which were optimized accor-ding to their morphological structures, average particle size and encapsulation rate. The measured particle size was(137.39±2.28) nm, and the encapsulation rate was 88.33%±1.82%. The mouse model of central nervous system inflammation was established by stereotaxic injection of lipopolysaccharide(LPS). TPGL and tripterygium glycosides(TPG) were administered intranasally for 21 days. The effects of intranasal administration of TPG and TPGL on behavioral cognitive impairment of mice due to LPS-induced central ner-vous system inflammation were estimated by animal behavioral tests, hematoxylin-eosin(HE) staining of hippocampus, real-time quantitative polymerase chain reaction(RT-qPCR) and immunofluorescence. Compared with TPG, TPGL caused less damage to the nasal mucosa, olfactory bulb, liver and kidney of mice administered intranasally. The behavioral performance of treated mice was significantly improved in water maze, Y maze and nesting experiment. Neuronal cell damage was reduced, and the expression levels of inflammation and apoptosis related genes [tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), BCL2-associated X(Bax), etc.] and glial activation markers [ionized calcium binding adaptor molecule 1(IBA1) and glial fibrillary acidic protein(GFAP)] were decreased. These results indicated that liposome technique combined with nasal delivery alleviated the toxic side effects of TPG, and also significantly ameliorated the cognitive impairment of mice induced by central nervous system inflammation.

OBJECTIVE To systematically reevaluate （umbrella review） the systematic review/meta-analysis of Tripterygium glycosides （TG） in the treatment of diabetic kidney disease （DKD）， in order to provide a higher quality evidence-based reference for TG in the treatment of DKD. METHODS The systematic reviews/meta-analysis of TG in the treatment of DKD were searched from CNKI， Wanfang， VIP， CBM， PubMed， Cochrane Library and Embase. The PRISMA 2020 statement， the AMSTAR 2 scale and the GRADE tool were used to evaluate the quality of the report， the quality of the methodology， and the quality of the evidence， respectively. The quantitative results of the included systematic review/meta-analysis were analyzed comprehensively. RESULTS A total of 18 systematic reviews/meta-analyses were included. PRISMA 2020 stated that 3 reports were complete， 13 reports had partial information defects， and 2 reports had serious information defects. The results of the AMSTAR 2 scale evaluation showed that 4 literature had low methodological quality， and 14 literature had very low methodological quality. GRADE tool evaluation results showed that there were 106 outcome indicators， including 34 intermediate-quality evidence accounted for 32.1%， 51 poor-quality evidence accounted for 48.1%， 21 very poor-quality evidence accounted for 19.8%， and there was no high- quality evidence. Comprehensive analysis of quantitative results of various outcome indicators showed that TG had definite improvement effects on the total effective rate of DKD， 24-hour urinary protein quantity and serum albumin， and the adverse drug reactions were different in every study. CONCLUSIONS The efficacy of TG in the treatment of DKD is relatively accurate， safety still needs to be paid attention to， and future studies with larger sample size need to be verified.

Objective:To investigate the efficacy of tripterygium glycoside tablets combined with irbesartan for chronic nephritis and its effect on 24-hour urine protein and inflammatory factor levels.Methods:Ninety patients with chronic nephritis who received treatment at The Second People's Hospital of Liaocheng from April 2018 to January 2020 were included in this study. They were randomly divided into an observation group and a control group, with 45 patients in each group. The control group was treated with irbesartan. The observation group was treated with tripterygium glycoside tablets combined with irbesartan. All patients were treated for 3 successive months. Clinical efficacy and adverse reactions were compared between the two groups. Changes in 24-hour urine protein level, symptom score, and inflammatory factor levels after treatment relative to those before treatment were compared between the two groups.Results:Response rate in the observation group was significantly higher than that in the control group [95.6% (43/45) vs. 80.0% (36/45), χ2 = 5.07, P = 0.024). Before treatment, there were no significant differences in 24-hour urine protein level, symptom score, and inflammatory factor level between the two groups (all P > 0.05). After treatment, the 24-hour urine protein level in the observation group was significantly lower than that in the control group [(1.42±0.01) g/24 hours vs. (1.95 ± 0.05) g/24 hours, t = 69.72, P = 0.012). The symptom score in the observation group was significantly lower than that in the control group [(0.78 ± 0.01) points vs. (1.33 ± 0.12) points, t = 30.64, P = 0.001]. Serum levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α in the observation group were significantly lower than those in the control group ( t = 15.70, P = 0.006; t = 96.55, P = 0.003; t = 43.41, P = 0.002). There was no significant difference in the incidence of adverse reactions between the two groups ( P = 0.694). Conclusion:Tripterygium glycoside tablets combined with irbesartan is highly effective on chronic nephritis. The combined therapy can remarkably decrease 24-hour urine protein levels, reduce symptom scores, and decrease inflammatory factor levels.

Effect of Tripterygium Glycosides on Differentiation and Balancing of Th17/Treg Cells in Rats With Experimental Colitis / 胃肠病学

Background: Immune factors play an important role in the pathogenesis of inflammatory bowel disease (IBD). Clinical studies have shown that tripterygium glycosides is effective for the treatment of IBD. Aims: To investigate the effect of tripterygium glycosides on differentiation and balancing of Th17/Treg cells in rats with experimental colitis. Methods: Experimental colitis was induced by TNBS-ethanol method in rats to evaluate the therapeutic effect of tripterygium glycosides. After intragastrically administered with normal saline (model group), tripterygium glycosides or mesalazine, respectively once a day for two weeks, the disease activity index (DAI) was assessed, and the colonic mucosal injury was examined macro- and microscopically. Mononuclear cells of mesenteric lymph nodes were extracted, and the levels of Th17/Treg-related cytokines in the supernatant were detected by ELISA method. The expression of proinflammatory cytokines in colon tissues was detected by immunohistochemistry. Results: The symptoms of experimental colitis were more severe in model group. DAI, gross morphological and histopathological score of colonic mucosal injury were significantly higher in model group than in tripterygium glycosides and mesalazine groups (P0.05). Compared with the model group, the levels of IL-23 and TNF-α in the supernatant of mesenteric lymph nodes mononuclear cells in mesalazine group, and the levels of IL-23, TNF-α and IL-6 in tripterygium glycosides group were significantly reduced (P0.05). In rats treated with mesalazine, the expression of IL-6 in colon tissues was down-regulated significantly (P<0.05). Conclusions: Tripterygium glycosides have the potential to inhibit the differentiation of Th17 cells and promote the differentiation of Treg cells in IBD. Regulating the imbalance of Th17/Treg cells might be one of the mechanisms of its therapeutic effect on IBD.

Effect of acupuncture on oxidative stress and apoptosis in ovarian hypofunction induced by Tripterygium Glycosides / 针刺研究

OBJECTIVE: To explore whether manual acupuncture stimulation of "Shenshu " (BL23), "Guanyuan" (CV4), "Zhongwan" (CV12) can improve the ovarian function by resisting oxidant stress and reducing apoptosis of granulosa cells in rats with ovarian hypofunction. METHODS: Forty female SD rats with normal estrous cycles were randomly divided into blank control, model, hormone therapy and acupuncture groups (n=10 rats in each group). The ovarian hypofunction model was established by gavage of Tripterygium Glycosides suspension (50 mg·kg-1·d-1) for 14 successive days. Rats of the hormone therapy group were treated by gavage of estrogen and progesterone, and those of the acupuncture group treated by manual acupuncture stimulation of bilateral BL23 or CV4 and CV12 alternatively by using uniform reinforcing-reducing method for 10 s every 5 min (3 times in 10 min). The treatment was performed once daily for 14 days. The blank group was given equal volume of normal saline daily. On the 9th day, the estrous cycle of each rat was observed by means of vaginal smear test. The ovarian index, serum estradiol (E2), follicle stimulating hormone (FSH), luteinizing hormone (LH), malondialdehyde (MDA) and superoxide dismutase (SOD) contents were detected by ELISA. Histopathological changes of the ovary tissue were observed by H.E. staining. The expressions of apoptosis-related proteins Bax and Bcl-2 and their mRNAs of the ovaries were determined by immunohistochemical staining and quantitative real time-PCR separately. RESULTS: The menstrual disorder rate was 100% in the model group, and was significantly higher than those in the hormone therapy (30%) and acupuncture (40%) groups (P<0.01). Following modeling, the ovarian wet weight and index, E2 and SOD contents, Bcl-2 protein and mRNA expressions were significantly decreased (P<0.01, P<0.05), and serum FSH, LH and MDA levels, Bax protein and mRNA expressions were significantly increased (P<0.05, P<0.01) in the model group in comparison with the blank control group. H.E. staining showed a large amount of connective tissue in the ovary, with fewer mature follicles, increase of atresia follicles, significant reduction of luteal tissue, and appearance of scarring tissue in the model group. Compared with the model group, there were more mature follicles, fewer atresia follicles, lower abnormal granulosa cell morphology and lower estrous cycle disorder ratio in both hormone therapy and acupuncture groups. After the interventions, the decreased ovarian wet weight and index, serum E2 and SOD contents, expressions of Bcl-2 protein and mRNA were significantly increased (P<0.05, P<0.01), and the increased levels of FSH and LH, MDA, expressions of Bax protein and mRNA were significantly decreased in both hormone therapy and acupuncture groups (P<0.05, P<0.01). The effect of acupuncture was significantly superior to that of hormone in up-regulating SOD, Bax and Bcl-2 protein expressions (P<0.01). CONCLUSION: Acupuncture can improve the menstrual disorder in rats with ovarian hypofunction, which is closely related to its effects in improving antioxidant stress ability and regulating the expressions of apoptosis-related protein and mRNA of ovarian gra-nulosa cells.

Objective:To compare the effects and multi-organ intervention of tripterygium glycosides(TG) tablet from Hunan Qianjin Xieli (QJ) and Zhejiang Deende (DED) on type Ⅱ collagen-induced arthritis (CIA) in rats. Method:The 72 SD rats were randomly divided into normal group, model group, QJ TG clinical group 2 times, 6 times equivalent dose group (QJ-TG 0.018, 0.054 g·kg-1), derende TG clinical group 2 times, 6 times equivalent dose group (DED-TG 0.018, 0.054 g·kg-1). The intragastric administration was started on the day after the first immunization, once a day. After the second immunization, the symptoms such as redness and swelling of joints were observed, and the clinical score of arthritis were evaluated. The materials were taken for pathological examination of the inflammatory joints on the 21th and 42th day. The concentration of alkaline phosphatase(ALP), alanine aminotransferase(ALT), aspartate aminotransferase(AST), gamma-glutamyltransferase(GGT), total bilirubin(TBIL), creatinine(CRE) and urea(UREA) in serum were detected by enzymatic assay. The rate of sperm deformity, testicular and ovarian tissue damage in the rat epididymis was assessed. Result:TG from two manufacturers attenuated the inflammation, redness, swelling and deformity of joints in CIA rats, reduced the clinical score and incidence of arthritis in CIA rats. Meanwhile, it also exhibited obvious reduction in all pathological features such as joint synovitis, pannus, cartilage erosion and bone destruction. There were significant differences between the QJ-TG high and low dose groups and the DED-TG high dose group compared with the model group (PP-1 group had a significant inhibitory effect on the clinical scores on the 15th and 18th days than the QJ-TG same dose group (P-1 dose of DED-TG, the white blood cell count and spleen index were significantly increased.At the same time, two different manufacturers of TG had no effect on body weight, organ index, digestive system, liver and kidney function, liver and kidney pathology of CIA model rats. QJ-TG and DED-TG all significantly increased the rate of male rats sperm malformation and significant damage to testicular seminiferous tubules and the toxicity increased with the increase of dose and time. while the mole reproductive toxicity of DED-TG was higher than that of QJ-TG at the same dose. In the DED-TG 0.054 g·kg-1 and QJ-TG 0.054 g·kg-1 group, there were only the reduction of vascular distribution in the ovarian tissue and the reduction of the corpus luteum, and no other toxic effects were observed. Conclusion:Two manufacturers TG2 times (0.018 g·kg-1) and 6 times (0.054 g·kg-1) clinical equivalent dose can delay the onset of CIA in rats, reduce the clinical score of arthritis, improve the pathological changes of joints, but have a certain degree of male reproductive toxicity. The high-dose DED-TG is more toxic than the QJ-TG.

Tripterygium wilfordii and its extracts have regulatory effects on innate immune cells including macrophages,dendritic cells,neutrophils,mast cells,NK cells,NKT cells,etc.,as well as a variety of innate immune molecules including cytokines,adhesion molecules,patterns recognition receptor( PRR) and the complement molecules,showing a regulatory effect in the pathogenesis of RA innate immunity. In this paper,the recent domestic and foreign researches on the pathogenesis of RA with innate immunity involved were reviewed and the research status of T. wilfordii and its extracts on the regulation of innate immunity involved in RA was summarized.

Identification of biomarkers to response of Tripterygium Glycosides Tablets acting on rheumatoid arthritis by integrating transcriptional data mining and biomolecular network analysis / 中国中药杂志

Growing clinical evidence shows that a partial rheumatoid arthritis( RA) patient treated with Tripterygium Glycosides Tablets( TGT) may fail to achieve clinical improvement. It is of great clinical significance to predict the therapeutic effect of TGT in RA. Therefore,the aim of the current study was to identify potential biomarkers for TGT treatment in RA. Affymetrix EG1.0 arrays were applied to detect gene expression in peripheral blood mononuclear cells obtained from 6 RA patients( 3 responders and 3 non-responders) treated with TGT. By integrating differential expression data analysis and biomolecular network analysis,360 mRNAs( 185 up-regulated and 175 down-regulated) and 24 miRNAs( 7 up-regulated and 17 down-regulated) which were differentially expressed between TGT responder and non-responder groups were identified. A total of 206 candidate target genes for the differentially expressed miRNAs were obtained based on miRanada and Target Scan databases,and then the miRNA target gene coexpression network and miRNA-mediated gene signal transduction network were constructed. Following the network analyses,three candidate miRNAs biomarkers( hsa-miR-4720-5 p,hsa-miR-374 b-5 p,hsa-miR-185-3 p) were identified as candidate biomarkers predicting individual response to TGT. Partialleast-squares( PLS) was applied to construct a model for predicting response to TGT based on the expression levels of the candidate gene biomarkers in RA patients. The five-fold cross-validation showed that the prediction accuracy( ACC) of this PLS-based model efficacy was 100.00%,100.00%,100.00%,66.67% and 66.67% respectively,and all the area under the receiver operating characteristic curve( AUC) were 1.00,indicating the highly predictive efficiency of this PLS-based model. In conclusion,the integrating transcription data mining and biomolecular network investigation show that hsa-mir-4720-5 p,hsa-mir-374 b-5 p and hsa-mir-185-3 p may be candidate biomarkers predicting individual response to TGT. In addition,the PLS model based on the expression levels of these candidate biomarkers may be helpful for the clinical screen of RA patients,which potentially benefit individualized therapy of RA in a daily clinical setting.

Effect of Tripterygium Glycosides Tablets on synovial angiogenesis in rats with type Ⅱ collagen induced arthritis / 中国中药杂志

To observe the effect of Tripterygium Glycosides Tablets on angiogenesis of rats with type Ⅱ collagen-induced arthritis( CIA) and on the tube formation of human umbilical vein endothelial cells( HUVEC) in vitro. The HUVEC were induced by 20 μg·L-1 vascular endothelial growth factor( VEGF) in vitro,and were treated with 0. 1,1,10 mg·L-1 Tripterygium Glycosides Tablets continuously for 7 hours. The numbers of branches of tube formation were measured. SD rats were immunized to establish CIA. CIA rats were treated with 9,18,36 mg·kg-1·d-1 Tripterygium Glycosides Tablets for 42 days. Histopathological examination( HE) was performed to observe the vascular morphology and vascular density in the synovial membrane of the inflamed joints. Immunohistochemistry and immunofluorescence were performed to observe the expression of platelets-endothelial cell adhesion molecule( CD31) and αsmooth muscle actin( αSMA) in synovial membrane. Immunohistochemistry and Western blot were performed to observe the expression of hypoxia-inducible factors 1α( HIF1α) and angiotensin 1( Ang1) in the synovial tissue. The results showed that the numbers of branches of tube formation of HUVEC induced by VEGF were improved,and declined significantly after treated by Tripterygium Glycosides Tablets. Compared with the normal group,the vascular density,CD31 positive expression,CD31 +/αSMA-immature and total vascular positive expression in the synovial membrane of the model group were significantly increased,and so as HIF1α and Ang1 in the synovium. Tripterygium Glycosides Tablets reduced the synovial vascular density and inhibited the positive expression of CD31,CD31+/αSMA-immature blood vessels and total vascular,but has no effect on CD31+/αSMA+mature blood vessels. Tripterygium Glycosides Tablets also inhibited the expression of HIF1α and Ang1 in synovial membrane of inflammatory joints. Our results demonstrated that Tripterygium Glycosides Tablets could inhibit the angiogenesis of synovial tissue in CIA rats and the tube formation of HUVEC,which is related to the down-regulation of HIF1α/Ang1 signal axis.

Study on mechanism of Cuscutae Semen flavonoids in improving reproductive damage of Tripterygium Glycosides Tablets in rats based on high-throughput transcriptome sequencing / 中国中药杂志

Tripterygium Glycosides Tablets has good anti-inflammatory and immunomodulatory activities,but its reproductive damage is significant. Previous studies of the research group have found that Cuscutae Semen flavonoids can improve spermatogenic cell damage caused by Tripterygium Glycosides Tablets by regulating spermatogenic cell cycle,apoptosis and related protein expression,but the mechanism of action at the gene level is still unclear. In this study,Illumina high-throughput sequencing platform was applied in transcriptional sequencing of spermatogenic cells of rats after the intervention of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets. Differentially expressed genes were screened out and the GO enrichment and KEGG pathway analysis of differentially expressed genes were conducted to explore the mechanism of Cuscutae Semen flavonoids in improving reproductive injury caused by Tripterygium Glycosides Tablets. The results showed that 794 up-regulated genes and 491 down-regulated genes were screened in Tripterygium Glycosides Tablets group compared with the blank group. Compared with Tripterygium Glycosides Tablets,440 up-regulated genes and 784 down-regulated genes were screened in the Cuscutae Semen flavonoids+Tripterygium Glycosides Tablets group. Among them,the gene closely related to reproductive function is DNMT3 L. Analysis of GO function and KEGG signaling pathway enrichment showed that the above differentially expressed genes were mainly enriched in cell,cell process,catalytic activity,binding,ovarian steroid synthesis,thyroid hormone and other functions and pathways. The thyroid hormone signaling pathway was the common enrichment pathway of the two control groups. In a word,Cuscutae Semen flavonoids has a good treatment effect on male reproductive damage caused by Tripterygium Glycosides Tablets. The mechanism may be closely related to up-regulation of DNMT3 L genes and intervention of thyroid hormone signaling pathway. At the same time,the discovery of many different genes provides valuable information for study on the mechanism of Cuscutae Semen flavonoids and Tripterygium Glycosides Tablets compatibility decreasing toxicity and increasing efficiency.

Effect of Tripterygium Glycosides Tablets on reproductive toxicity in female rats with Ⅱ type collagen induced arthritis / 中国中药杂志

The aim of this paper was to observe the toxic effect of Tripterygium Glycosides Tablets( TG) on the reproductive system of Ⅱ type collagen induced arthritis( CIA) male rats,and to explore the toxic mechanism preliminarily. Fifty SD rats were randomly divided into normal control group( Con),model group( CIA),Tripterygium Glycosides Tablets clinical equivalent dose groups of 1,2,4 times( 9,18,36 mg·kg-1),10 rats in each group,and were given by gavage once a day for 42 days after the first immunization.The organ indexes of uterine and ovarian were calculated on days 21 and 42. Histopathological and morphological changes of uterine and ovarian were observed under optical microscope. The concentration of estradiol( E2),follicle-stimulating hormone( FSH),luteinizing hormone( LH),17α-hydroxylase( CYP17 A1) and cytochrome P450 19 A1( CYP19 A1) in serum were detected by ELISA. Immunohistochemistry was used to observe the expression of Bax and Bcl-2 related proteins in the apoptosis pathway of uterus and ovary. The results showed that compared with the Con group,CIA group could reduce the number of uterine glands( P<0.05),but no significant changes were observed in other groups. Compared with the CIA group,there were no significant changes in the coefficients of uterus and ovary in the Tripterygium Glycosides Tablets groups. The number of uterine glands,total follicles in the ovary,mature follicles and corpus luteum,the distribution of blood vessels and mitochondria had a certain inhibitory trend,and also slightly increased the number of atresia follicles,but the histopathological quantitative indicators were not statistically different. Except that 2 times clinical dose of Tripterygium Glycosides Tablets could significantly reduce the content of CYP19 A1( P<0. 05) after 42 d administration,there were no significant changes in serum estrogen E2,FSH,LH and estrogen synthesis key enzymes CYP17 A1 in each administration group. Medium and high doses of Tripterygium Glycosides Tablets could increase the expression of apoptotic protein Bax in uterine and ovarian tissues( P<0. 05,P<0. 01),and all the administration groups could inhibit the expression of apoptotic inhibiting protein Bcl-2( P <0. 05,P<0. 01,P<0.001),42 d was more obvious than 21 d. In conclusion,4 times and less than 4 times Tripterygium Glycosides Tablets did not cause obvious toxicity and histopathological changes in the reproductive organs of CIA rats,but it could reduce the level of serum estrogen synthesis key enzyme CYP19 A1 and affect the content of apoptosis-related proteins Bax and Bcl-2 in uterus and ovary tissues. The relevant mechanism needs further study.

Nuclear transcription factor E2-related factor( Nrf2) and heme oxygenase-1( HO-1) as well as mitochondrial mediated apoptosis-related protein expression levels of Bax and Bcl-2 in hepatic tissue were measured by Western blot.Within 24 hours of administration,6 male mice in Jiangsu group and 2 female mice in Zhejiang group were dying; compared with normal ones,liver coefficients of mice in Zhejiang,Shanghai,Jiangsu and Hunan groups were significantly increased,thymus coefficients in the first two groups were significantly reduced,as well as the lung coefficients of Fujian group mice,the rest was normal. In addition to Hubei group,serum AST,ALT or ALP levels of mice were increased,while TBi L were not being affected. Histopathological changes and apoptosis of liver cells were observed in all mice,and the degree of severity was ranked as Jiangsu,Zhejiang,Shanghai,Hunan,Hubei and Fujian group. All Tripterygium Glycosides Tablets increased the MDA and reduced the content of T-SOD,CAT or GSH in liver tissue while inhibited Nrf2,HO-1 and Bcl-2,increased the protein expression level of Bax( except Hunan group). Tripgerygium Glycosides Tablets from 6 manufacturers all resulted in liver function damage and liver histopathological changes,especially in Jiangsu,Hubei and Fujian,and the mechanism may related to inhibit Nrf2/HO-1 oxidative stress pathway and activate Bax/Bcl-2 apoptosis pathway to mediate lipid peroxidation and induce liver cell apoptosis. Triptolide A may be one of the main toxic components of Tripgerygium Glycosides Tablets that causing drug-induced liver injury. This study was conducted on normal mice with super dose medication,so the relevant results are for reference only.

Comparative study on dose-toxicity-effect of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets on CIA model rats / 中国中药杂志

The aim of this paper was to compare the properties of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets from dose-effect-toxicity on type Ⅱ collagen-induced arthritis( CIA) in rats. SD rats were randomly divided into eight groups,including normal group,model group,Tripterygium Glycosides Tablets groups( 1 times equivalent dose 0.009 g·kg-1,4 times equivalent dose 0.036 g·kg-1,16 times equivalent dose 0.144 g·kg-1),Tripterygium wilfordii Tablets groups( 1 times equivalent dose 0.007 5 mg·kg-1,4 times equivalent dose 0.030 mg·kg-1,16 times equivalent dose 0.120 mg·kg-1). Beginning on the first immunization,Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets administered intraperitoneally once a day. After the second immunization,the symptoms such as redness and swelling of joints were observed,and the clinical score and incidence of arthritis were evaluated. HE and Masson staining were used to examine the histopathological changes of joints. The expression level of anti-type Ⅱ collagen antibody Ig G in serum was detected by ELISA,routine testing of blood components,the concentration of ALP( alkaline phosphatase),ALT( alanine aminotransferase),AST( aspartate aminotransferase),GGT( gamma-glutamyltransferase),TBi L( total bilirubin),CRE( creatinine) and UREA( urea) in serum were detected by enzymatic assay. The rate of sperm deformity in the epididymis was evaluated under light microscope. The extent of damage to the testis and ovarian tissue was assessed by HE staining. Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets attenuated the inflammation,redness,swelling and deformity of joints and reduced the clinical score and incidence of arthritis in CIA rats. Meanwhile,it also exhibited obvious reduction in all pathological features such as joint synovitis,pannus,cartilage erosion and bone destruction. Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets reduced Ig G in a dose-dependent manner,and Tripterygium Glycosides Tablets is better than Tripterygium wilfordii Tablets( P<0.05 or P<0.01). The high doses of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets could significantly increase the organ coefficient of liver and spleen and reduced RBC and HGB in CIA rats( P<0.01),and severity leading to death. Gastric mucosal injury and morphological changes of liver and kidney were not observed in CIA rats of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets treatment group. The 4 and 16 times doses of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets could significantly increase serum ALT,GGT and decrease CRE( P<0.05 or P<0.01). Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets could increase the sperm deformity rate and damage the testicular seminiferous tubules of CIA male rats. Severity increased with dose and time increasing. The effect of Tripterygium Glycosides Tablets( 16 times) is more significant than Tripterygium wilfordii Tablets( 16 times). Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets significantly delayed onset of arthritis and inhibited the paw edema and arthritic score. Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets also caused male reproductive damage,high dose affected hematopoiesis,and maximum dose leading to death. Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets all depended on dose-effect-toxicity manner. Anti-arthritis effect of Tripterygium Glycosides Tablets is better than Tripterygium wilfordii Tablets,but the toxicity of Tripterygium Glycosides Tablets maximum dose is more obvious. The relevant conclusions of our study will provide experimental references for clinical rational use of drugs,and further clinical studies are needed to confirm our conclusions.

Effect of Tripterygium Glycosides Tablets on immune-induced liver and kidney function in patients with rheumatoid arthritis based on data mining / 中国中药杂志

This paper aims to investigate the effect of oral administration of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on immune inflammatory index in patients with rheumatoid arthritis,in order to explore the compatibility mode of traditional Chinese medicine in the treatment of rheumatoid arthritis. Medical records of hospitalized patients with rheumatology at the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from June 2012 to December 2017 were collected. The combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine was adopted for the experimental group,while the simply administration of Tripterygium Glycosides Tablets were adopted for the control group. SPSS 21. 0 was used to analyze the changes of general conditions and immune inflammatory metabolic indexes in the two groups of RA patients. The association rules were analyzed by SPSS Clementine 14. 2 software Apriori module,and the random walk model was evaluated by ORACLE 10 g tool. The results showed that a total of 1 220 patients with rheumatoid arthritis met the requirements of this study,including 322 in the experimental group and 898 in the control group. Before treatment,there was no significant difference in age and duration between the two groups. The difference value of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR in the two groups of RA patients decreased before and after treatment,and the experimental group was superior to the control group in reduction of Ig A,Ig G,RF,CCP-AB,hs-CRP and ESR.The control group was superior to the experimental group in reduction of Ig M( P<0. 01 or P<0. 05). Compared with before treatment,ALT,AST,ALP,GGT,CREA,BUN,b-MG,MA,TRU and Ig U all increased,with statistically significant differences( P<0. 01).The UA of the two groups of RA patients decreased after treatment,with statistically significant differences( P<0. 01). The experimental group was superior to the control group in reduction of UA,with statistically significant differences( P < 0. 05 or P < 0. 01). The herbs adopted in the prescriptions of 1 220 patients were mainly classified into four categories,namely spleen-sweating herbs,blood-activating and stasis-relieving herbs,phlegm and phlegm-relieving herbs,and heat-clearing and antidote herbs. The results of association rule analysis indicated a significant correlation between the single-flavored Tripterygium Glycosides Tablets,oral Chinese medicine and immune inflammation,and improvement of liver and kidney function indexes. The results of the random walk model analysis indicated that the experimental group's Ig M and hs-CRP were superior to those of the control group in terms of random fluctuation maximum,walking positive growth rate,comprehensive evaluation index increasing rate,comprehensive improvement rate,comprehensive evaluation index recording times,and expected improvement value. The results of this study showed that the single administration of Tripterygium Glycosides Tablets can effectively improve the immune inflammatory metabolic index of patients with rheumatoid arthritis,and the combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine could alleviate the immune inflammatory index of RA patients and reduce liver and kidney dysfunction compared with simple oral administration. The comprehensive evaluation Ig M and hs-CRP in the group of combined administration of Tripterygium Glycosides Tablets and traditional Chinese medicine were better than those in the group of the Tripterygium Glycosides Tablets. There was a long-term correlation between the comprehensive evaluation index and the intervention measures of the two groups of patients.

Clinical symptoms effect of Tripterygium Glycosides Tablets alone or combined with methotrexate in treatment of rheumatoid arthritis: a Meta-analysis / 中国中药杂志

To systematically review the improvement effects of Tripterygium Glycosides Tables( TGT) alone or in combination with methotrexate( MTX) on the clinical signs and symptoms of rheumatoid arthritis( RA),and provide a basis for the rational use of TGT in clinic,in the current study,six literature databases including CNKI,Wan Fang,VIP,PubMed,EMbase,and Cochrane Library,were systematically searched,according to the inclusion and exclusion criteria. Review Manager 5.3 software was used to input the literatures,and we assessed the risk bias on the level of outcome indicators for each included literature. A total of 18 literatures were included,and the classification results showed that: compared with MTX,TGT alone can reduce the number of joint swelling( MD =0. 18,95%CI[-1.06,1.42],P = 0.78) and joint tenderness( MD =-0.06,95% CI[-1.69,1.56],P = 0.94) in RA patients with the same effect as MTX. In terms of drug combination,TGT combined with MTX had an advantage over MTX alone in lessening the morning stiffness time( MD = 18. 24,95% CI[12. 64,23. 84],P < 0. 000 01) of RA,joint tenderness( MD = 2. 65,95% CI[1. 85,3. 44],P<0.000 01) and joint swelling( MD = 3.01,95% CI[2.09,3.39],P< 0.000 01). In conclusion,this Meta-analysis suggest that TGT alone was superior to MTX in improving joint swelling and tenderness in RA patients,TGT combined with MTX may improve the clinical manifestation of RA patients better than MTX alone.

Meta-analysis of efficacy and safety of Tripterygium Glycosides Tablets combined with desloratadine in treatment of chronic urticarial / 中国中药杂志

To analyze the efficacy and safety of Tripterygium Glycosides Tablets combined with desloratadine as well as desloratadine alone in the treatment of chronic urticaria by Meta-analysis,in order to provide evidence-based reference for clinical treatment.PubMed,CBM,Wan Fang,VIP database and CNKI database were retrieved to collect randomized controlled trials( RCT) about Tripterygium Glycosides Tablets combined with desloratadine( test group) as well as desloratadine alone( control group) in the treatment of chronic urticaria. Meta-analysis was performed by using Rev Man 5. 3 software after data extraction and quality evaluation( a total of 15 RCTs were included,involving 1 411 patients). Meta-analysis showed that the total effective rate( RR = 1. 28,95%CI[1. 22,1. 35],P<0. 000 01) and the quality of life improvement rate( RR = 1. 49,95% CI[1. 33,1. 66],P< 0. 000 01) of the test group were better than those of the control group,and the recurrence rate( RR = 0. 29,95%CI[0. 21,0. 40],P<0. 000 01) was significantly lower than that of the control group,with statistically significant differences; there was no statistically significant difference in the incidence of adverse reactions( RR = 1. 02,95%CI[0. 68,1. 53],P = 0. 92) compared with the control group. Based on the included RCTs,the efficacy of Tripterygium Glycosides Tablets combined with desloratadine in the treatment of chronic urticaria were superior to those of desloratadine alone,with similarity in safety. However,due to the low quality of RCTs and the lack of large-scale multi-center studies,the results shall not be further verified by clinical trials.

Long-term effect of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on adulthood fertility / 中国中药杂志

To preliminarily investigate the effect of Tripterygium Glycosides Tablets( TGT) combined with traditional Chinese medicine( TCM) on the fertility and female menstruation on persons who have took during childhood. The children with henoch-schonlein purpura( HSP) or henoch-schonlein purpura nephritis( HSPN) who treated with TGT under 18 years old and now older than 18 years old( including 18 years old) during January 1998 to December 2010 were selected in our research. The content of follow-up visit included marriage,marriage age,fertility and child health; and unmarried female patients were asked whether they had menstrual abnormalities. The data of the unmarried female patients,including age,clinical classification,TCM syndrome type,initial dose and other related factors that may affect menstrual cycle,was analyzed by using binary logistic regression analysis. A total of 195 patients who met the criteria were followed up in this study,and 26 patients married for more than 1 year. Among the 26 married patients,1 HSP patient had no birth planning due to rheumatoid arthritis,and the remaining 25 patients all had given birth or were pregnant. The 169 unmarried patients included 89 female patients. Among the 89 female patients,4 cases refused to tell the menstrual situations,72 cases had normal menstruation( 84. 7%),13 cases had abnormal menstruation( 15. 3%),and there was no case of amenorrhea. Logistic regression analysis results showed that the age,clinical classification,TCM syndrome type and initial dose had no correlation with abnormal menstruation. Our results demonstrated that TGT has no effect on adulthood fertility among patients who took TGT combined with traditional Chinese medicine during childhood.
