Objective To analyze the adverse drug reactions(ADRs)of edaravone in treatment of patients with acute cerebral infarction(ACI)by reviewing Chinese medical literature and to evaluate safety of edaravone treatment in ACI.Methods Publications from Pubmed and Chinese Biomedical Literature Datababe(CBMdisc)were reviewed and the ADR of edaravone was analyzed among the published 8645 cases.Literatures about randomed-control clinical trails(RCTs)on security of edaravone for treating ACI Was analyzed by meta-analysis.Results Abnormal hepatic function,especially mild elevation of aminotransferase,renal dysfunction and skin rash induced by edaravone were tIle most common ADRs.Among 8645 patients,ADRs were reported in 283(3.27 % ).The meta-analysis in RCTs showed that between the group treated with a combination of edaravone and routine and the group treated with routine treatment only,there was no significant difference in the occurrence rate of ADRs(OR=1.18,95 % CI0.70-2.00,P=0.536),elevation of aminotransferase(OR=1.23,95 % CI 0.57-2.68,P=0.595)or renal dysfunction including albuminutia,increased level of serum ereatinine and nitrogen(OR=1.65.95 % CI0.57- 4.79.P=0.353).Conclusion Edaravone has a low ADRs OCCurrence rate and iS safely used in cerebral infarction treatment.

Objective To investigate the inhibitory effect of recombinant LIGHT-Fe gene on the proliferation of human esophageal carcinoma cell line Eea109. Methods LIGHT-Fc expression vector was transfected into human esophageal squamous carcinoma cell line Eca109 by using DOTAP liposomal transfection reagents. The effects of LIGHT-Fc gene on the proliferation of esophageal carcinoma cell line Eca109 in vitro were detected by cell growth curve and MTr assay. Forty-five nude mice were equally divided into Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group. Carcinogenesis and pathological expression of the esophageal carcinoma tissues were observed. Results The expressions of LIGHT receptors were detected in Eca109 cells. The proliferation of Eca109 cells was inhibited after trasfecting LIGHT-Fc gene into Eca109 cells. The numbers of tumors generated in Eea109/Wt group, Eca109/neo group and Eca109/LIGHT group were 12, 11 and 5, with statistical significance between Eca109/LIGHT group and the other two groups (X2 =6.652, 4.821, P <0.05). The result of histopatholagical examination indicated that the tissue necrosis appeared significantly in tumors derived from Eea109/LIGHT cells. Conclusions The growth of esophageal squamous carcinoma cell line Eca109 can be suppressed by LIGHT-Fc gene whether in vitro or in vivo.

AIM: To investigate the effects of advanced glycation end products (AGEs) on protein and mRNA expression of macrophage inflammatory protein-1? (MIP-1?) in cultured human umbilical vein endothelial cells(HUVECs). METHODS: HUVECs were cultured with AGEs at different concentrations for 24 h and at a concentration of 400 mg/L for different time.The levels of mRNA and protein expression of MIP-1? in cultured HUVEC were detected by in situ hybridization and Western blot, respectively. RESULTS: In situ hybridization showed that after exposure of HUVECs to AGEs at different concentrations (100 mg/L, 200 mg/L, 400 mg/L) for 24 h, the average integrated optical density values (18.76?3.17, 26.58?1.61, 34.23?2.25) of MIP-1? mRNA expression in HUVECs were higher than that in control group (13.83?1.24, P

Objective To examine the proliferative effect of synthetic cyclic human cartilage glycoprotein-39 (HCgp39) on T cell of collagen-induced arthritis (CIA) rat,and to explore the role of HCgp39 in rheumatoid arthritis (RA).Methods We established the rat model of the collagen-induced arthritis (CIA).The T lymphocytes were isolated and incubated with HCgp39.Proliferation of T cells was determined by cell counting kit-8.Results Two weeks after the first immunization,T cell response to HCgp39 was more significant in CIA groups than in controls( P<0.01 ),and the response was associated with disease course ( r =0.732,P<0.01 ) and anti- HCgp39 antibody ( r =0.460,P<0.01 ).A strong correlation between T cell proliferation and pannus ( r =-0.516,P<0.01 ),synovium score ( r =-0.346,P<0.01 ) was also observed.Besides,the levels of anti- HCgp39 antibody and comp in each CIA group were significantly higher than in controls( P<0.01 ),and the anti- HCgp39 antibody strongly correlated with disease course( r=0.346,P<0.01 ) and comp( r =0.235,P<0.01 ).Conclusion The proliferative response of T cell to HCgp39 was found in the early stage of CIA rat,and the HCgp39 peptide antibody was detected in serum,suggesting that the HCgp39 antigen plays an important role in the pathogenesis of early RA.
