Tripterygium wilfordii Hook F (TwHF) is one of the most commonly used and effective traditional Chinese herbal medicines against rheumatoid arthritis (RA). Both Tripterygium Glycoside Tablets (TGT) and Tripterygium wilfordii Tablets (TWT) are the representative TwHF-based agents enrolled into the 2019 edition of Medicine Catalog for National Basic Medical Insurance, Injury Insurance, and Maternity Insurance. However, individual differences in TGT/TWT response across patients usually exist in the process of treating RA, implying that the clinical application of the two agents may not be standardized leading to the ineffective treatment and the risk of side effects. Growing evidence show that the bioactive constituents of TwHF may often have toxicity, the package insert of TGT and TWT may not be described in detail, and the therapeutic windows of the two agents are narrow. Thus, it is an urgent task to develop a standardized clinical practice guideline for TGT and TWT in the treatment of RA. In the current study, a group of clinical experts of traditional Chinese medicine and Western medicine in the research field of rheumatism diseases, pharmacists, and methodologists of evidence-based medicine were invited to select the clinical questions, to determine the levels of the evidence and the strength of the recommendations, and to develop the recommendations and good practice points. The guideline is formed based on the combination of clinical research evidence and expert experience (evidence-based, consensus, supplemented by experience). The clinical problems which are supported by clinical evidence may form recommendations, and the clinical problems without clinical evidence may form experts’ suggestions. Both recommendations and experts' suggestions in this guideline summarized the clinical indications, usage, dosage, combined medication, and safety of TGT and TWT against RA systematically and comprehensively, which may offer a professional guidance in the context of the clinical application of the two TwHF-based agents.

To systematically evaluate the adverse drug reaction(ADR) of Tripterygium Glycosides Tablets(TGT) in the treatment of rheumatoid arthritis(RA). Four Chinese databases(CNKI, VIP, WanFang, SinoMed) and three English databases(Cochrane Library, EMbase, PubMed), from the time of database establishing to August 2019, were systematically retrieved to collect literature on the treatment of all types of RA with TG. Screening literature and extracting data according to inclusion and exclusion criteria. All studies were assessed by using internationally recognized methodological quality assessment tools or reporting quality evaluation criteria, with data being extracted and Meta-analyzed. There were 79 studies included, randomized controlled trials(RCT) containing TGT in the treatment group, non-randomized controlled trials(non-RCT), case series, case reports, and RCT containing TGT only in the control group were covered. There were in the control group; 765 ADR of 2 214 patients in 30 RCT(treatment group given TGT), 11 non-RCT and 7 case reports. The results of Meta-analysis of these 48 literatures showed that the overall incidence of ADRs was 0.23(95%CI[0.22,0.24]); ADR mainly occured in the reproductive, gastrointestinal, skin and accessories, blood, hepatobiliary system damage and the incidence of ADR in systems mentioned about respectively were 0.14(95%CI[0.12,0.17]),0.07(95%CI[0.06,0.08]),0.06(95%CI[0.04,0.07]),0.04(95%CI[0.03,0.05]),0.04(95%CI[0.03,0.05]). Further subgroup analysis results showed that the incidence of total ADR, especially the gastrointestinal, reproductive and cutaneous ADR of patients with treatment alone was higher than that in those paients with MTX or MTX+LEF therapy; The incidence of ADR, especially the gastrointestinal ADR, was also positively correlated with daily dose and course of treatment, while the incidence of different systems ADR was also correlated with different drug manufacturers, for instance, damage on the female reproductive system occurs most frequently in Hunan manufacture TGT administration, same as the damage on skin and accessories induced by TGT from Jiangsu manufacture. Above all, The clinical treatment of TGT for RA will cause multi-system ADR, with the highest incidence in the reproductive system, followed by the gastrointestinal system, which is closely related to the way of medication(monotherapy), daily dose, course of medication and drug manufacturer. Therefore, it is recommended that, in the treatment of RA, using TGT in combination, low dose or short-course medication, take measures to protect the reproductive system, stomach and liver, and paying attention to the drug manufacturer as well response of patients during administration should be valued to avoid ADRs to the maximum possibility.

To evaluate the clinical efficacy of single administration of Tripterygium Glycosides Tablets(TGT) or combined administration with methotrexate(MTX) against rheumatoid arthritis(RA) based on American College of Rheumatology(ACR) efficacy standard. Six databases, namely CNKI, WanFang, VIP, PubMed, Embase and Cochrane Library, were retrieved for randomized controlled trials(RCT), and clinical trials were screened out according to the preset inclusion and exclusion criteria. Then, the study quality was evaluated by the risk assessment tools. Data extraction and analysis were performed by using RevMan 5.3 software for Meta-analysis. Sensitivity analysis and publication bias analysis were made to test the stability and reliability of results. Until December 2018, a total of 1 709 articles were obtained, and finally 10 clinical RCT studies with a total of 1 184 patients were included. As a result, the single administration of TGT showed a significantly better ACR efficiency(RR=1.31, 95%CI[1.15, 1.49], Plt;0.000 1) than methotrexate(MTX). The combined administration of TGT and MTX showed a significantly better ACR efficiency(RR=1.28, 95%CI[1.20, 1.38], Plt;0.000 01) than the single administration of MTX. In conclusion, the single administration of TGT and the combined administration of TGT and MTX were more effective in achieving ACR20, ACR50, ACR70 compliance than the single administration of MTX. Further validations based on more RCT studies with high-quality are required.

To systematically evaluate the effects of Tripterygium Glycosides Tablets alone or in combination with methotrexate(MTX) and leflunomide(LEF) on the levels of pro-inflammatory cytokines in patients or animal models with rheumatoid arthritis(RA), and to provide reference for clinical application and related basic research, this study systematically searched databases of CNKI, VIP, WanFang, PubMed, Embase and Cochrane Library, collected relevant clinical or animal experimental studies, used risk assessment tools to evaluate the quality of research, and used Revman 5.3 software to conduct Meta-analysis or descriptive analysis of the outcome indicators included in the literatures. Of the 1 709 papers retrieved, 3 clinical studies and 12 animal experiments were included. The results showed that compared with MTX alone, Tripterygium Glycosides Tablets combined with MTX could further reduce the expression levels of peripheral blood TNF-α(SMD=-8.88,95%CI[-10.77,-6.99],Plt;0.000 01),IL-1β(Plt;0.000 01) and IL-6(SMD=-8.63, 95%CI[-10.57,-6.69], Plt;0.000 01) in RA patients. Compared with LEF alone, the combination of Tripterygium Glycosides Tablets and LEF could not further reduce the expression levels of TNF-α(P=0.20), IL-1β(P=0.17), IL-6(P=0.31). In RA animal model, compared with model group, Tripterygium Glycosides Tablets could reduce the expression levels of peripheral blood IL-1β(SMD=-6.29,95%CI[-9.64,-2.93],Plt;0.000 2)in peripheral blood(SMD=-1.39,95%CI[-1.77,-1.02],Plt;0.000 01), joint fluid(Plt;0.000 01) and paw plasma(P=0.02), and also reduce the expression levels of TNF-α in RA animal model group. Compared with MTX alone, Tripterygium Glycosides Tablets alone reduced the same levels of TNF-α(P=0.42) and IL-6(P=0.08) in joint fluid, while Tripterygium Glycosides Tablets combined with MTX could further reduce the levels of IL-6(P=0.000 1) in joint fluid; compared with LEF alone, Tripterygium Glycosides Tablets have the similar effects on reducing the expression levels of peripheral blood TNF-α(P=0.16), IL-1β(P=0.32), IL-6(P=0.12), while Tripterygium Glycosides Tablets combined with LEF could further reduce the expression levels of TNF-α(P=0.008), IL-1β(P=0.02), IL-6(Plt;0.000 1) in peripheral blood. Therefore, Tripterygium Glycosides Tablets combined with MTX could further reduce the expression levels of pro-inflammatory cytokines in peripheral blood of RA patients. Tripterygium Glycosides Tablets alone could reduce the expression levels of pro-inflammatory cytokines in peripheral blood and local joint of RA animal models. Tripterygium Glycosides Tablets combined with MTX or LEF could further reduce the express levels of pro-inflammatory cytokines in peripheral blood of RA animal models. Due to the limitation of literature, this conclusion needs to be further validated.

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],P0. 000 01) of RA,joint tenderness( MD = 2. 65,95% CI[1. 85,3. 44],P0.000 01) and joint swelling( MD = 3.01,95% CI[2.09,3.39],P0.000 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.

The aim of this study was to systematically evaluate the clinical efficacy of Tripterysium Glycosides Tablets( TGT) alone or in combination with methotrexate( MTX) in the treatment of rheumatoid arthritis( RA) based on the laboratory index criteria and to provide a basis for the clinical application of TGT against RA. Six databases including CNKI,Wan Fang,VIP,PubMed,EMbase and Cochrane were retrieved for randomized controlled trials( RCT) about TGT alone or combination with MTX in the treatment of RA.Then risk assessment tools were used for quality evaluation of the studies,and data extraction and analysis were conducted by using Rev Man 5.3 software for Meta-analysis. A total of 1 709 articles were retrieved,and finally 25 studies were included,with a total sample size of 2 507 cases. Meta-analysis results showed that between TGT alone and TGT alone,MDESR=-2. 66,95%CI[-8.17,2.86],P = 0.35; MDCRP=-2.38,95%CI[-9.01,4.24],P = 0.48; between TGT combined with MTX and MTX alone,MDESR= 8.74,95%CI[6.72,10.76],P0.000 01; MDCRP= 5.37,95%CI[3.71,7.03],P0.000 01; SMDRF= 1.05,95%CI[0.51,1.60],P = 0.000 1.The effect of TGT on decreasing CRP and ESR in RA patients was similar to the MTX. In addition,TGT combined with MTX were more effective in decreasing CRP,ESR,RF than MTX alone. However,due to the potential bias in the included studies,more and high-quality randomized controlled trials would be needed to improve the level of evidence.

To evaluate the status and risk factors for the misdiagnosis of femoral head osteonecrosis, providing the basis for accurate diagnosis of osteonecrosis of femoral head.The data of 314 hospitalized patients were collected from March 2015 to March 2016, and the risk factors for osteonecrosis of femoral head were analyzed by Logistic regression model. Misdiagnosis was defined that the diagnosis given on the first time was different from that on the second time or that given by expert group with the same symptoms and signs. The general data, predisposing factors, time of onset, hospital visits, clinical manifestations, X-ray film of hip joint, MRI and other data were statistically analyzed.Total 127 patients experienced misdiagnosis (up to 40.8%). Among them, the patients with osteonecrosis of femoral head misdiagnosed as other diseases accounted for 77.2% and the patients with other diseases misdiagnosed osteonecrosis of femoral head accounted for 22.8%. Statistical analysis showed that the predisposing factors, history of glucocorticoid and alcohol intake, diseased lower limb, pained lower limb, hidden disease attack, the level of first reception hospital and expert were significantly related with the misdiagnosis of femoral head osteonecrosis based on the logistic regression model (Misdiagnosis rate of femoral head necrosis is high. Hidden disease attack and low level of first reception expert are the high risk factors associated with the misdiagnosis in which the femoral head necrosis was misdiagnosed as other diseases, however, glucocorticoid intake history is the protective factor of misdiagnosis. Low level of first reception expert is the high risk factor associated with the misdiagnosis in which other diseases were misdiagnosed as necrosis of femoral head.

To optimize a measuring method of osteonecrotic area by analyzing the average osteonecrotic areas and osteonecritic volume using multi layer MR images.The MRI images of 87 cases (120 hips) of ONFH(ARCO II) were collected retrospectively from January 2011 to January 2012 in Wangjing Hospital of China Academy of Chinese Medicine Science. PHILIPS Achieval 1.5T MR was used to obtain coronal TSE T1 weighted (T1W) images. The scanning parameters were shown as follows:slice thickness, 3.5 mm; gap, 0.3 mm; images repetition time(TR), 500 ms;echo time(TE), 20 ms;field of view (FOV), 374 mm;total 12 layers. According to the distribution rule of osteonecrotic lesion, the layer of coronal T1-weighted imaging showing most of femoral neck was marked as layer 0(L0). The layers before L0 were marked in sequence L1, L2, L3, L4... , and the layers after L0 were marked in sequence L-1, L-2, L-3, L-4... . Auto CAD 2007 was used to measure the percentage of osteonecrotic area and calcu late the average data, and then decreased the layer from low to high layer successively based on frequency of osteonecrotic occurrences. First, the layer with lowest frequency of osteonecrotic occurrenoses L3 was removed, then calculated the average osteonecrotic area of the ramaining 8 layers. L5, L4, L-2, L-1, L3 layers were gradually removed, resulting in the calculation of avereage osteonecrotic areas in 7, 6, 5, 4, 3 layers. These areas were compared to the osteonecrotic volume in MR imagings, leading to the optimization of the fewest layer measuring method of osteonecrotic area using a statistical analysis.The percentage of osteonecrotic volume in 120 hips was 0.333±0.151. The average osteonecrotic areas of 9 to 3 layers were 0.321±0.117, 0.317±0.136, 0.312±0.147, 0.333±0.153, 0.348±0.172, 0.365±0.174, 0.377±0.202 respectively. There were no statistical differences of the average osteonecrotic areas and osteonecrotic volume in 9 to 3 layers(The results of 4(L0, L1, L2, L3) layers measuring method and osteonecrotic volume measuring method are similar. The 4 layers measuring method is an accurate, convenient, valuable method measuring the esteonecrotic area with the fewest layers, which is worth to be popularized in clinical application.
