Objective To evaluate the relationship between the mechanism underlying docosahexaenoic acid (DHA)-induced regulation of angiopoietin expression and Src-suppressed C kinase substrate (SSeCKS) in human brain vascular pericytes (HBVPs) subjected to oxygen-glucose deprivation and restoration (OGD/R).Methods HBVPs were seeded in 96-well or in 6-well plates at a density of 2× 105 cells/ml and divided into 5 groups (n =18 each) using a random number table:control group (group C),OGD/R group,DHA group (group D),SSeCKS gene silencing group (group S) and SSeCKS gene silencing plus DHA group (group SD).The model of OGD/R injury was established as follows:the cells were subjected to O2-glucose deprivation for 24 h in glucose-and serum-free culture medium aerated with 94％ N2-5％ CO2-1％ O2 followed by restoration of O2-glucose supply for 6 h in high-glucose DMEM culture medium in normal atmosphere.DHA was added at 1 h before hypoxia with the final concentration of 40 μmol/L in group D.Small interfering RNA induced SSeCKS gene silencing in S and SD groups.Subsequently,DHA with the final concentration of 40 μmol/L was added at 1 h before hypoxia in group SD.At 6 h of reoxygenation,the cell survival rate was determined by CCK-8 assay,the amount of LDH released was detected using ELISA,and the expression of SSeCKS,angiopoietin-1 (Ang-1) and Ang-2 was detected by Western blot.Results Compared with group C,the cell survival rate was significantly decreased,the amount of LDH released was increased,the expression of SSeCKS and Ang-1 was down-regulated,the expression of Ang-2 was up-regulated,and Ang-1/Ang-2 ratio was decreased in group OGD/R,and the expression of SSeCKS was down-regulated in group S (P＜0.05).Compared with group OGD/R,the cell survival rate was significantly increased,the amount of LDH released was decreased,the expression of SSeCKS and Ang-1 was up-regulated,the expression of Ang-2 was down-regulated,and Ang-1/Ang-2 ratio was increased in group D (P＜O.05),and no significant change was found in the parameters mentioned above in group SD (P＞0.05).Compared with group D,the cell survival rate was significantly decreased,the amount of LDH released was increased,the expression of SSeCKS and Ang-1 was down-regulated,the expression of Ang-2 was up-regulated,and Ang-1/Ang-2 ratio was decreased in group SD (P＜0.05).Conclusion The mechanism by which DHA increases the ratio of Ang-1/Ang-2 may be totally related to up-regulation of SSeCKS expression in HBVPs subjected to OGD/R.

Objective:To identify the function of extracellular soluble vimentin that promotes proliferation, activation and chemotaxis of inflammatory cells. Methods: The proliferation of rat splenocytes stimulated with vimentin was evaluated in vitro. The lymphocyte counts and vimentin-antibody levels of peripheral blood in mice immunized with vimentin were detected in vivo. Peritoneal macrophages were collected and cultured with different concentrations of vimentin to detect the effect on phagocytosing chicken red blood cells. The chemotaxis of NIH3T3 fibroblast towards vimentin was observed in transwell chamber. Results:In vitro vimentin dose dependently promoted the proliferation of splenocytes. The proliferation indexes of primed and naive splenocytes cultured with 16μg/ml vimentin were reached up to ( 196. 0 ± 9. 7 )% and ( 208. 9 ± 4. 6 )% respectively without significant difference. In vivo vimentin significantly enhanced the lymphocytes number(109 L-1)of peripheral blood(5. 74±0. 51 vs. 1. 69±0. 13)and the levels of vimentin specific antibody( OD value 2. 31 ± 0. 06 vs. 0. 19 ± 0. 08 ) that shown no significant difference from immunization with vimentin plus CFA. In vitro vimentin dose dependently stimulated phagocytic ability of macrophages and performed the chemotactic effects on NIH3T3 fibroblasts. Conclusion:Extracellular soluble vimentin promotes the proliferation,activation and chemotaxis of concerned inflammatory cells and possesses the functions as an alarmin.

Objective To evaluate the long-term therapeutic effect of hyaluronic acid on adults with Kashia-Beck disease and the applicability of the joint dysfunction index.Methods A cluster-randomized,starch tablets-controlled trial was carried out depending on the joint dysfunction index of assessment for therapeutic efficacy on Kashin-Beck disease and self-assessment by patients of the Treatment Effect of Kaschin Beck Disease in Criterion.A total of 99 adults with Kashia-Beck disease were randomly divided into two groups:treatment group including 50 patients were intra-articular injected hyaluronic acid in knee weekly for 4 weeks,and the control group including 49 patients were treated with oral starch tablets for 3 months,2 tablets each time,3 times a day.We carried out 48 months follow-up and assessed the applicability of Kashia-Beck disease with treatment of hyaluronic acid.Results The improvement rates of joint dysfunction index were 80.0％ (40/50),83.0％ (39/47),86.4％ (38/44),85.7％(36/42),80.0％(36/45),and 47.1％(16/34) for 1 week and 1,2,3,6,48 months in treatment group,respectively,which were significantly higher than those of corresponding control group 25.0％ (12/48),28.3％ (13/46),33.3％ (16/48),25.0％ (10/40),30.0％ (12/40),and 21.4％ (6/28),and the differences were statistically significant between corresponding groups (x2=29.744,28.236,17.762,30.665,21.537,4.406; all P ＜ 0.05).Before treatment,the treatment group and control group in the joint dysfunction index scores were 7.59 ± 1.82 and 6.89 ± 1.97(t =1.837,P ＞ 0.05),respectively.After treatment,1 month follow up of the treatment group and control group in the joint dysfunction index scores were 3.44 ± 1.71 and 5.55 ± 2.34(t =4.972,P ＜ 0.01),respectively; 6 months follow up were 3.46 ± 2.78 and 6.10 ± 1.83(t =5.102,P ＜ 0.01),respectively; 48 months follow up were 5.13 ± 2.88 and 6.81 ± 3.07(t =2.219,P ＜ 0.05),respectively.The satisfaction of 85.1％ (40/47) in treatment group was significantly higher than that of 60.9％(28/46) in control group (Z =-4.012,P ＜ 0.01).Kappa value between joint dysfunction index and the overall evaluation of the treatment group after treatment was 0.526,which belong to moderate intensity of consistent degree (P ＜ 0.01).Conclusion The therapeutic effect of intra-articular injection of hyaluronic acid on adults with Kashia-Beck disease is significant and lasting,and the joint dysfunction index has better applicability to evaluate the long-term therapeutic effect.
