Total glucosides of paeony can affect hepatic dysfunction of patients with moderate or severe liver damage caused by methotrexate and leflunomide in rheumatoid arthritis patients / 中华风湿病学杂志

Objective To investigate the effect of total glucosides of paeony(TGP) on hepatic dysfunction caused by Methotrexate (MTX) and Leflunomide (LEF) in patients with moderate or severe rheumatoid arthritis (RA).Methods From July 2010 to February 2011,204 cases with definite-diagnosed rheumatoid arthritis were included in three hospitals in Anhui province.All these patients suffered from moderate or severe rheumatoid arthritis and they were divided randomly into two groups,the therapeutic groups were treated with TGP combined with MTX and LEF and the control group were treated without TGP.The incidence of hepatic dysfunction was observed.Statistical anylysis was carried out by using t test and x2 test.Results One hundred and ninty-four patients had completed observation for at least 12 weeks.In the therapeutic group,only 10 of 105 patients had hepatic dysfunction compared to 31 of 89 patients in the control group.The incidence of hepatic dysfunction of the therapeutic group was significantly lower than the control group.After 12 weeks treatment with TGP,the effective respohse rates of the therapeutic group was 81.9％,which was higher than 74.6％ in the control group.The good response rate in the therapeutic group was 21.6％,which was better than 11.7％ in the control group.Although the difference between the two groups was not statistically significant,we could observed the tendency of increasing in effectiveness and the good response rate in the therapeutic group when compared with the control group.Conclusion TGP can decrease the incidence of hepatic dysfunction during the treatment with MTX and LEF,and it may improve the therapeutic effecacy of patients with RA.

The expression and clinical significance of Toll-like receptor 7 and 9 in peripheral blood B cells of patients with systemic lupus erythematosus / 中华风湿病学杂志

Objective The aim of this study is to examine the expressions of Toll like receptor (TLR) 7 and TLR9 in the peripheral blood B lymphocytes of SLE patients and to analyze the correlation between TLR7/9 and clinical parameters. Methods lntracellular expression of TLR7/9 in the peripheral blood CD19+Blymphocytes was analyzed in 50 SLE patients and 30 healthy controls by flow cytometry. The difference of intracellular TLR7/9 expression levels in two groups was compared. Furthermore,the correlation between TLR7/9 expression and clinical parameters such as ESR, CRP, complement 3 (C3), complement 4 (CA), the level of serum IgG, anti-double stranded DNA antibody, anti-nuclear antibodies, SLEDAI score and urine protein excretion level, were analyzed. Results Compared with healthy subjects, the proportion of B cells expressing TLR7 and TLR9 was higher among SLE patients. Positive correlation was observed between TLR7 expression levels and clinical measurement of the SLEDAI and ESR. Negative correlation was observed between TLR7 expression levels and serum C3 levels. Positive correlation was observed between TLR9 expression levels and SLEDAI scores. Negative correlation was observed between TLR9 expression levels and serum C3 levels. Conclusion TLR7 and TLR9 expression is increased in the peripheral blood B cells of SLE patients, and correlates well with clinical parameters.

Efficacy of Total Glucosides of Paeony in the Treatment of Undifferentiated Spondyloarthropathies and Its Mechanism / 中国中医药信息杂志

Objective To evaluate the efficacy of total glucosides of paeony(TGP) in the treatment of undifferentiated spondyloarthropathies(uSpA) and investigate its mechanism.Methods One hundred and sixteen cases of uSpA were randomly assigned to 2 groups,one group was treated with TGP and diclofenac sodium,the other group with SASP and diclofenac sodium.The efficacy and side effects of the two groups were compared after 12 weeks treatment.The level of IL-6,IL-10 and TNF-? was determined at the same time.Result After 12 weeks treatment,the major clinical manifest and the indexes of disease activity were no difference of statistical significance in the two groups.The incidence of parenterally side effects was 8.6% in TGP group,and 25.9% in SASP group.There was difference at statistical significance between the two groups(? 2 =6.042,P=0.014).Before treatment,the level of IL-6,IL-10 and TNF-? in the serum of two groups were no statistical difference,while there was obviously difference after 12 weeks treatment(t= 2.672,2.483 and 2.088,P=0.009,0.014 and 0.039).Conclusion The efficacy of TGP and SASP has no significant difference in the treatment of uSpA.But the incidence of parenterally side effects in the TGP group was less than SASP group.The mechanism of efficacy of TGP may be related to inhibiting the production of IL-6,IL-10 and TNF-?.
