Objective To systematically assess the effectiveness and safety of acupuncture and moxibustion for treatment of rheumatoid arthritis. Methods Articles were searched from databases, i.e., CNKI, VIP, WanFang Data, CBM, Embase, and PubMed. Articles about RCT on acupuncture and moxibustion for rheumatoid arthritis and traditional medicine therapy were under meta-analysis. Results Totally 24 articles involving 2006 patients were included. The results of meta-analysis indicated that the overall effective rate of treatment in the group receiving acupuncture and moxibustion was higher than that in the drug group, with statistical significance [OR=2.73, 95%CI (2.18, 3.41), Z=8.78, P<0.000 01]. Sub-group analysis showed that:acupuncture and moxibustion showed statistical significance in decreasing serum RF levels compared with drug therapy [MD=-2.92, 95%CI (-5.60, -0.25), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum ESR levels compared with drug therapy [MD=-2.99, 95%CI (-4.78, -1.21), P<0.05]. Acupuncture and moxibustion showed statistical significance in decreasing serum CPR levels compared with drug therapy [MD=-1.44, 95%CI (-2.44, -0.44), P <0.05]. Conclusion The overall effective rates of acupuncture and moxibustion for rheumatoid arthritis and the decreasing levels of RF, ESR, CRP are superior to drug therapy, but it still needs larger samples, multi-center, and high quality RCT to verify.

Objective To study the antigen presenting function of keratinocytes to CD8 + T cells with specific TCR.Methods PAM212transfectants,which express H-2K b /ovalbumin complex,aa257-264,were used as stimulating cells,and naive or primed CD8 + T cells with ovalbumin specific TCR were used as respon-ders.3 H-thymidin uptake values were used as indicators of T cell proliferation.Results With prestimulation of IFN-?,the proliferation of primed T cells but not naive T cells could be stimulated by PAM-OK cells.Conclusion Keratinocytes have the potential to stimulate the proliferation of TCR specific CD8 + T cells,which might explain the persistence of local immune reaction in some involved skin.

Objective To investigate the expression of haptoglobin(Hp)mRNA and protein in nor-mal human epidermal cells and human keratinocyte cell line-HaCaT cells.Methods In situ hybridization and RT-PCR were used to detect the expression of Hp mRNA in normal human epidermal cells and HaCaT cells.Immunohistochemistry was used to detect the expression of Hp on normal human epidermal cells.Im-munohistochemistry and Western blot were used to detect Hp expression on HaCaT cells.Results There was Hp mRNA expression in normal human keratinocytes and HaCaT cells.There was no Hp mRNA expres-sion in normal human epidermal Langerhans cells.There were some Hp positive dendritic cells in normal human epidermis.There was no obvious Hp protein staining in the HaCaT cells by immunohistochemistry.There was Hp protein band from HaCaT cells by Western blot.Conclusions There is Hp mRNA expression in normal human keratinocytes and HaCaT cells which suggests that normal human keratinocytes and HaCaT cells have the ability to synthesize Hp protein.Normal human epidermal Langerhans cells have no ability to synthesize Hp protein.There is small amount of Hp protein in HaCaT cells.

Objective To evaluate the clinical value of determination of composition of kidney stones by shap and density and of prediction of the efficacy of extracorporeal shock-wave lithotripsy (ESWL) by X-rays. Methods The data of 358 patients were analyzed,with 204 male and 154 female and with 276 cases of solitary stones and 82 cases of multiple stones.Determine the composition of kidney stones by shap and density,predict the efficacy of ESWL by X-rays,and choose the appropriate method of treatment.Analyze stone chemical property by Infrared stone composition automatic analyzer to checkout the prediction results before surgeries.
