To observe the levels of platelet-activating factor (PAF), interleukin-6 (IL-6) and IL-17 in peripheral blood of rats with adjuvant arthritis (AA), and the effects of Xinfeng Capsule (XFC), a compound traditional Chinese herbal medicine.

Objective: To investigate the effects of chitosan (CHI) and PC-chitosan (PC CHI) coated membranes on the proliferation, migration, and hemocompatibility of vascular endothelial cells. Methods: CHI and PC-CHI were separately sprayed on the bottom of culture dish evenly to form the polymer membrane; the cylinder was made of 316 L stainless steel flake. Pig iliac endothelial cells (PIEC) were cultured on the polymer membranes, the stainless steel bottom of the cylinder, and the untreated bottom of culture dish (as blank control). Then the cell morphology was observed by light microscope and scan electron microscope; cell proliferation was measured by Cell Counting Kit-8 (CCK 8); and cell migration was also assayed. Whole blood activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FiB), and thrombin time (TT) were examined by clotting method. Results: PIEC grew well on the membranes of CHI and PC-CHI, with normal morphology. After 24 h culture, the proliferation rates of PIEC were 88. 8% and 77. 8% on CHI and PC-CHI membranes, respectively. The survived PIEC on CHI and PC-CHI membranes were significantly more than those on 316 L stainless steel flake(P<0.01), and those on CHI membrane were significantly more than those on PC-CHI membrane(P<0.01). After 72 h culture, the numbers of migration cells on CHI and PC-CHI membranes were significantly more than those on 316 L stainless steel flake(P<0.01), and those on PC-CHI membrane were significantly more than those on CHI membrane(P<0.01). APTT in PC-CHI, 316 L stainless steel flake, and blank control groups were significantly longer than that of CHI group(P<0.01, P<0.05), and FiB levels in the former 3 groups were higher than that of CHI group(P<0.01). Conclusion: Coating with CHI and PC-CHI can improve the proliferation and migration of vascular endothelial cells on the culture dishes, indicating an excellent biocompatibility of CHI and PC-CHI membranes. PCPCH membrane has more potent antithrombotic effect than CHI does.

?-Est. Besides,?-Est could promote the expression of ER ? by HSC at the concentration of 10 -7 mol/L but not its metabolites. Conclusion The present results indicate that ?-Est may attenuate hepatic fibrosis and the possible mechanism is via the action of its metabolites.

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.
