3 ?g/well.All BALB/c mice immunized with pJME by im.and gene gun injection,and JE inactivated vaccines by ip.injection survived for 21 days.BALB/c mice immunized with pJE by im.injection and gene gun injection partially survived for 21 days.Titres of neutralization antibody produced with pJME were higher than pJE.Protective immunity and titre of neutralization antibody produced by im injection was the same as gene gun injection(im/gene gun injection: 1∶320/1∶320) at day 21.The antibody from BALB/c mice sera after twice pJME immunization only reacts with JEV-E protein. Conclusions Expression efficacy of proteins encoded by pJME and pJE in transfected cells is different.Expression level of related proteins was dependant on recombinant amount for transfection in a certain degree.Immunity effect induced with pJME was higher than pJE.The efficacy of DNA immunization produced by gene gun injection was higher than im.injection.Titres of neutralization antibody induced by DNA immunization were correlated to efficacy of protective immunity.Neutralization antibody from BALB/c mice sera produced by pJME immunization contained anti-E antibody against JEV-E protein.

OBJECTIVE:To establish a method for determining the concentration of vinorelbine bitartrate in human plasma, and study the pharmacokinetic process of vinorelbine in human plasma. METHODS:The samples were extracted with Solid-phase extraction(SPE). LC-MS/MS was performed on the column of Agilent Extend C18 with the mobile phase of 5 mmol/L ammonium ac-etate solution(pH10.5)-acetonitrile-methano1(18∶10∶72,V/V/V)at the flow rate of 0.4 ml/min,the ion source was ESI and MRM mode was used to scan positive ion detection. The ion reaction of quantitative analysis was m/z 779.50→m/z 122.10 (vinorelbine) and m/z 811.60→m/z 224.50 (internal standard, vinblastine). 3p97 was used to calculate the pharmacokinetic parameters. RE-SULTS:The determination was not interfered by endogenous impurities,and there was no matrix effect;the lowest limit of quantita-tive analysis was 2.0 ng/ml with the linear range of 2.0-4 000.0 ng/ml(r=0.997 8);the linear range of vinorelbine in plasma was. The intra-day and inter-day precisions and accuracy results were all in line with the acceptable limit across all concentrations. t1/2γ of 30 mg/m2,40 mg/m2 Vinorelbine Emulsion for Injection groups and 30 mg/m2 Vinorelbine for Injection group were(37.958 ± 34.256)、(47.835±54.231)、(76.873±40.537)h respectively,cmax were(1 426.250±397.562)、(1 700.125±624.669)、(2 187.500± 828.040)ng/ml respectively,AUC0-48 h were(75 839±19 551)、(82 088±14 207)、(95 318±18 208)mg·h/L respectively. CONCLU-SIONS:The method is rapid,sensitive and specific,and suitable for the determination of vinorelbine and pharmacokinetic study. Metabolic processes of vinorelbine can be described as first order process of three-compartment model in cancer patients.

Objective To investigate the changes of inositol 1,4,5-triphosphate receptor typeⅠ(IP3RⅠ)expression in the myocardial tissue of rats with endotoxic shock and probe the possible mechanisms of myocardial depression.Methods Thirty-three male Wistar rats were divided into four groups:control group (n=6) were injected normal saline(4ml/kg),and the other 3 groups (n=9) were injected endotoxin via femoral vein with a different dose of 10mg/kg,5mg/kg,and the artificial sacrificed group(10mg/kg,the rats were sacrificed when the mean arterial pressure was first rapidly decreased,then gradually increased to the normal level).IP3RⅠexpression in the myocardial tissue of rats was detected by immunohistochemistry,Western blot and colloidal gold immunoelectron microscopy technique.Results IP3RⅠexpressions were increased significantly in each group of rats with endotoxic shock than in the control group (P<0.01),and most obviously enhanced in the the artificial sacrificed group.The expression of IP3RⅠwas related to the level of mean arterial pressure.Ectopic expression of IP3RⅠwas observed around the cell membrane of the cardiac myocytes.Conclusion (1)The expression of IP3RⅠenhances in the myocardial tissue of rats with endotoxic shock,and exists ectopic expression.(2) The expression of IP3RⅠwas related to the level of mean arterial pressure.(3) IP3RⅠ may be related to the cardiac contractility and involved in the regulation of mean arterial pressure.

The inflammatory reaction after acute cerebral infarction can aggravate the cerebral ischemic reperfusion injury.Activation of peroxisome proliferator-activated receptors-γ(PPAR-γ) has neuroprotective effects by which induces anti-inflammatory actions in cerebral ischaemia,thus as a potential novel pharmacological target for ischemic stroke was regarded.Acupuncture can improve cerebral ischemia injury by inhibiting synthesis of inflammatory cytokines,downregulating expressions of inflammatory mediators and adhesion molecule,suppressing the functions of inflammatory cells.Therefore,it will be a promising orientation to sift the effective acupuncture for that can stimulate the activation of PPAR-γ,and the research of mechanism of acupuncture on anti-inflammatory reaction after cerebral ischemic by activating PPAR-γ dependent pathways.
