Objective To observe effects of Xinfeng capsule (XFC) on platelet parameters,ultrastructure,p-selectin and therapeutic effect on rheumatoid arthritis (RA) patients in active phase.Methods Platelet parameters,p-selectin and reactive indexes of 60 RA patients in active phase were detected.RA patients were divided into XFC treated group (35 examples) and Zhengqing Fengtongning (ZQF) control group (25 examples) randomly.After a course of treatment,the therapeutic effect and changes of platelet parameters,p-selectin,reactive indexes of two groups were observed.Setting up a normal control (20 examples) and detecting above-mentioned indexes.Observing platelet ultrastructure of two examples with transmission electron microscope of per groups.Results Compared with normal control group,PLT,PCT,MPV,CD62P of RA patients in active phase was obviously increased.Platelet ultrastructure was obviously damaged.The excellence rate of XFC exceeded ZQF control group.After being treated,platelet ultrastructure of the two groups were obviously improved,and XFC group was better than ZQF group.Compared with ZQF group,PLT,PCT,CD62P were obviously decreased in XFC group.PLT,PCT were positively correlated with CD62P,IgG,ESR,CRP,RF,arthrpain,arthrocele.And PLT was positively correlated with arthrtenderness,morning stiffness time.Conclusion PLT and PCT of RA patients in active phase were increased,and have correlation with reactive indexes.It suggests that PLT,PCT can reflect reactiveness of RA as objective indexes.XFC can not only treat inflammation and delay the aggravation of RA patient by improving platelet ultrastructure.

OBJECTIVE: To observe the effects of Xinfeng Capsule (XFC), a compound Chinese herbal medicine, on behaviors and myocardial ultrastructure in adjuvant arthritis (AA) rats. METHODS: Fifty-five rats were randomly divided into normal control group, untreated group, methotrexate (MTX) group, Tripterygium wilfordii glycosides tablet (TGT) group and XFC group. There were 11 rats in each group. Except for those in the normal control group, the rats in the other groups were all intracutaneously given 0.1 ml Freund's complete adjuvant in the right hind limb. Changes of behaviors and myocardial ultrastructure of the rats in different groups were observed. RESULTS: Voix pedis' swelling and arthritis index in XFC, MTX and TPT groups were all obviously improved as compared with the untreated group. After XFC treatment, the autonomic activities were obviously increased, number of errors in exercise period and test period were obviously decreased, step-down latency (SDL) was lengthened and escape latency (EL) was shortened. Overall structure of myocardial myofibril and the majority of cristae was intact in XFC group. The effects of XFC in improving the behaviors and myocardial ultrastructure were better than those of MTX and TPT. CONCLUSION: Changes of behaviour and myocardial ultrastructure of AA rats can be observed. XFC can improve the myocardial ultrastructure of AA rats as well as their behaviors.

Objective To investigate the effect of ghrelin on PAI-1 secretion in HepG2 cells induced by TNF-αand the effect of p-38 MAPK.Methods HepG2 cells were cultured.The concentration of TNF-α used to treat the HepG2 cells wag selected.The effect of ghrelin on PAI-1 secretion induced by TNF-α was detected by ELISA,the p-38 MAPK expression was investigated by Western blot.Results The concentration of PAI-1 was increased when cells were exposed to different concentration of TNF-α.The p-p38 MAPK expression was increased when the cells were exposed to TNF-α,ghrelin could inhibit the increase of PAI-1 secretioN induced by TNF-α.The expression of p-p38 MAPK was decreased when the cells were pretreated with ghrelin.Conclusion PAI-1 secretion were increased after TNF-α in-creasing.Ghrelin could inhibit PAI-1 secretion via p38 MAPK.

Objective To select the calibrator for the conventional measurement system of serum a-Amylase (Amy).Methods The Amy levels of forty frozen serum samples were detected by the IFCC reference method (reference system),the conventional system A which used the Bioassay routine reagent and Randox calibrator,and was calibrated by the Roche PNPG7 method,and the conventional system B which used the Bioassay routine reagent and Randox calibrator,and was calibrated by the Rondox liquid stable PNPG7 method,respectively,and the acceptability of the two conventional systems was evaluated.Results The regression equations of the measurement values between the IFCC reference method and the conventional systems A and B were Y =0.964X +0.376 and Y =1.095X + 3.131,respectively.Among them,X and Y represented the results of the IFCC reference method and the conventional system,respectively.Compared with the IFCC reference method,the results of the conventional system A was reliable.Condusion With the guidance of the IFCC reference method,the domestic biochemical reagents matched with the suitable calibrators may provide the acceptable results.

Objective:To study the characterization of NK cell line co-transfected with hSCF and hIL-15 gene.Methods:pcDNA3-hSCF and pcDNA3-hIL-15 were transfected into NK-92 cell line with LipofectAMINETM,RT-PCR was used to identify NK-92 cell which express hSCF and IL-15,the activity of supernantes was respectively assayed by TF-1 and CTLL-2 cell line. CD3, CD16, CD56, CD25, CD48, CD54, CD69 and CD95 molecules were tested by FACS.Results:We established NK-92S15 cell line which express hSCF and hIL-15 steadily, proliferation ability demonstrated it had more extensive assembling trend,growing with enough cell number,the cytotoxicity of NK-92S15 cell was decreased compared with parental cell line when incubated with rhIL-2.CD56 and CD16 showed on difference while CD25,CD48, CD54 and CD95 decreased significantly.Conclusion:The characterization of NK-92 could be changed by co-transfecting with hSCF and hIL-15 gene, which was benefit to observe the character of NK cell activation and cytotoxicity related molecules. The gene transfection of NK-92 cell made it suitable for further study.

Objective:To observe the effects of effects of Xinfeng capsule(XFC) on platelet parameters(platelet count,thrombocytocrit,mean platelet volume,platelet distribution width) and on the serum levels of cytokines(IL-1?,TNF-?,IL-10) in adjuvant arthritis(AA) rats.Methods:40 SD masculine rats were averagely divided into groups of normal control,model control,XFC treatment,methotrexate(MTX) and tripterygium wilfordii polycoride tablet(TPT) alone,with 8 in each.Except for the rats of normal group,the others were intracutaneously injected with 0.1 ml of Freund′s complete adjuvant in the right hindlimb.The changes of platelet parameters (PLT,PCT,PDW,MPV) were observed by Sysmex XT-2000i automatic cytoanalyze and serum cytokines(IL-1?,TNF-?,IL-10)were analyzed with ELISA kit.Results:1.Compared with those of normal control,platelet count,thrombocytocrit,IL-1?、TNF-? of AA rats were obviously increased and IL-10 was obviously decreased in the model groups(P0.05).3.PLT and PCT of the rats were positively correlated with serum contents of IL-1? and TNF-?,as well as voix pedis′swelling and arthritis index(AI).In addition, IL-10 concentration in the serum was negatively correlated with PLT and PCT(P
