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.

[Effect of Tripterygium Glycosides Tablets on reproductive toxicity in male rats with Ⅱ type collagen induced arthritis].

The aim of this paper was to observe the toxic effect of Tripterygium Glycosides Tablets 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 index of testis and epididymis were calculated on days 21 and 42.

[Meta-analysis of laboratory index of Tripterygium Glycosides Tablets in treatment of rheumatoid arthritis].

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.

[Clinical symptoms effect of Tripterygium Glycosides Tablets alone or combined with methotrexate in treatment of rheumatoid arthritis: a Meta-analysis].

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.

[Comparative study on dose-toxicity-effect of Tripterygium Glycosides Tablets and Tripterygium wilfordii Tablets on CIA model rats].

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.

[Effects of Tripterygium Glycosides Tablets from 6 different manufacturers on acute liver injury of normal mice].

The aim of this paper was to compare the performance of acute liver injury in mice induced by Tripterygium Glycosides Tablets from 6 different manufacturers,and to explore the toxicity mechanism from the perspective of oxidative stress and apoptosis preliminarily. Male or female mice were randomly divided into normal group,Zhejiang group,Hunan group,Hubei group,Shanghai group,Jiangsu group and Fujian group. Mice in Tripgerygium Glycosides Tablets groups were given 16 times the clinical equivalent dose( 300 mg·kg-1) Tripgerygium Glycosides Tablets by oral administration for one time,mice were executed in 24 h after lavaged.

[Effect of Tripterygium Glycosides Tablets on reproductive toxicity in female rats with Ⅱ type collagen induced arthritis].

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.

[Overview of reproductive toxicity studies on Tripterygium wilfordii in recent 40 years].

This paper summarizes the research progress of reproductive toxicity of Tripterygium wilfordii from 1979,and the toxicity characterization,damage mechanism,and attenuated measures are summarized. It was found that,the reproductive toxicity caused by T. wilfordii is mainly distributed on components of Tripterygium glycosides,triptolide,tripchlorolide,and clinically preparations,such as Leigongteng Tablets and Tripterygium Glycosides Tablets.

Long-time qingyan formula extract treatment exerts estrogenic activities on reproductive tissues without side effects in ovariectomized rats and via active ER to ERE-independent gene regulation.

The reproductive tissues are negatively influenced by estrogens in hormone therapy. Qingyan formula ethanol extract (QYFE)'s estrogenic effects and safety on reproductive tissues after long-term administration and its mechanism via estrogen receptor (ER) pathway haven't been studied. Here, we characterized its estrogenic effects using ovariectomized rats together with studies for further molecular characterization.

Effect of planting patterns on yield, nutrient accumulation and distribution in maize and soybean under relay intercropping systems.

Planting patterns affect nitrogen (N), phosphorus (P), and potassium (K) acquisition and distribution in maize and soybean under intercropping conditions. Here we reveal that strip relay-intercropping increases the N, P, and K uptake and distribution across plant organs (root, straw, and seed) of maize and soybean, accelerates the dry-matter production of intercrop-species, and compensates the slight maize yield loss by considerably increasing the soybean yield. In a two-year experiment, soybean was planted with maize in different planting patterns (SI, 50:50 cm and SII, 40:160 cm) of relay-intercropping, both planting patterns were compared with sole cropping of maize (SM) and soybean (SS).
