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.

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 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.

The present study aims to investigate the kinetic histocytochemical changes of acupoints in different condition. The expression of tryptase (+) mast cells, histamine (HA) , serotonin (5-HT) and nociceptive neuropeptides including calcitonin gene-related peptide (CGRP) and substance P (SP) were observed by immunohistochemistry combined with confocal technology. Mast cells were labeled with anti-mast cell tryptase antibody and simultaneously with HA or 5-HT primary antibodies to observe their co-expression. The results showed that: (1) SP and CGRP were expressed more highly on the cutaneous nerve fibers of "Hegu" (LI 4) after acupuncture stimulation than that of the control. Mast cells aggregated in close proximity to the blood vessels in intra-epidermis and dermis, and some of them with degranulation in the lower dermis and subcutaneous tissue of "Hegu" (LI 4). Both mast cells and their granules appeared with HA (+) and 5-HT (+) expression at stimulated LI 4 sites, while a few intact mast cells with a little expression of 5-HT and HA were distributed in areas of non-stimulated Ll 4. (2) The acupoints in different locations such as Baihui (GV 20), Weishu (BL 21), Zhongwan (CV 12) and LI 4 had the same constituent but the contents were different. (3) The histocytochemical responses of acupoints sensitized by the Gastric mucosa injury (GMI) were also investigated. GMI resulted in neurogenic plasma extravasation by Evans Blue (EB) in the skin of the acupoints over the back and abdomen, which mostly occurred in the T9-T11 dermatomere. The EB extravasation dots just like acupoints sensitization appeared after GMI and disappeared gradually during the natural self-recovery of the gastric mucosa. More SP and CGRP positive nerve fibers were distributed in EB dots than in regions beside EB dots and in the control, mostly distributed in the nerve fibers around both the vessels and root of hair follicle. Mast cells also aggregated and degranulated to release algogenic substances of 5-HT and HA around the vessels in areas of the EB dots. Collectively the acupoints displayed the same histocytochemical responses due to either acupuncture stimulation or GMI. This may potentially be the histocytochemical basis in the local acupoints and acupoints displayed kinetic changes in different condition.

Objective:To investigate the effects of site specific (124 HNFTAGDLGP STIVGSAAFNMF145 ) antibody of Sodium calcium exchanger ( NCX) on calcium transient in single ventricular myocytes of normal adult rats .Methods: Isolated adult rat hearts were perfused using Langendorff method and single ventricular myocytes were then obtained .The ventricular myocytes were incubated with Fuar-2/AM and 2% bovine serum albumin for about 40 min and then,the fluorescence images were recorded when excitation wavelengths were 340 nm and 380 nm using ion imaging system.Fluorescence value F340/F380,length of cell shortening ,time to 90%restore( TR90 ) and calcium sensitivity ( ratio of F340/F380 and cell shortening ) were calculated.Results:The site specific antibody of NCX increased F340/F380 and decreased TR90 in single ventricular myocytes ,but had no more significant effect on calcium sensitivi-ty.Pretreatment with KB-R7943 or Nicardipine could significantly inhibit the TR 90 decrease or F340/F380 increase induced by the anti-body.Pretreating ventricular myocytes with combination of KB-R7943 and Nicardipine ,the antibody had no more significant effects on calcium transient.Conclusion:Site specific ( 124 HNFTAGDLGPSTIVGSAAFNMF145 ) antibody of NCX could increase calcium transient and accelerate the decrease of intracellular calcium during diastole ,which mainly related to its effects of activating L-type Ca2+channel and NCX.
