Objective To establish an animal model of passive transferred myasthenia gravis(PTMG) in C57BL/6 mice aged 4 to 5 weeks with nicotinic acetylcholine receptor monoclonal antibody-mAb35 so as to decide the effective dose of mAb35 required to induce PTMG and to supply animal model for further study of the pathogenesis and immunotherapy of human MG.Methods The C57BL/6 mice aged 4 to 5 weeks in the experimental group were divided into three subgroups(E1,E2,E3),injected intraperitoneally(i.p.) with 0.2 ml of Ringer's buffer solution containing 0.5,1.0 or 1.5 mg/kg capital monoclonal antibody mAb35 of acetylcholine receptor respectively.The control group(N) were injected i.p.with 0.2 ml of Ringer's buffer solution without mAb35.To decide whether the model was successful,the clinical symptoms,ultrastructural changes of the mice as well as pharmacological and electrophysiological evaluation were observed and the serum levels of acetylcholine receptor antibody(AChRAb) were detected.Results All mice in the experimental groups were induced of clinic symptoms of myasthenia.The features in pharmacology,electrophysiology,ultrastructure and increased level of acetylcholine receptor antibody were in accordance with those of MG patients.Conclusion The model of PTMG can be successfully induced in C57BL/6 mice with mAb35 at effective dose of 1.0 mg/kg.The method is convenient and reliable.A fine animal model is established for experimental study of myasthenia gravis in children.

Objective: To explore the antagonism of selenium enriched Spirulina platensis(Se-SP) to hepatocirrhosis by enhancement of cell proliferation and selenoenzyme activity.Method: The male SD rat hepatocirrhosis model was induced by thioacetamide(TAA),and Se-SP was supplemented.Hepatic histological analysis was performed and relative content of collagen(RCC %) was estimated using IBAS 2000 system after Masson’s staining.Glutathione peroxidase(GSH-Px),thioredoxin reductases(TR) and malondialdehyde(MDA) in hepatocyte as well as hyaluronic acid(HA) in serum were determined.Expression index of proliferating cell nuclear antigen(PCNA) in hepatocytes was detected by immu-nohistochemistry,and the level of synthesis of DNA in regenerative hepatocytes was analyzed by radio-immunity for incorporation of 3H-TDR.Results: Hepatocirrhosis was induced by TAA at 9w of the expeiment,and the obvious antagonism of Se-SP to hepatocirrhosis was obsewed after Se-SP supplementa-tion.12.5% rats of Se-Sp group were completely recovered at 15w of the experiment(6w after withdrawal of TAA).GSH-Px and TR activity in hepatocytes as well as PCNA and 3H-TDR incorporation rate in hepatocytes were obviously enhanced(P

Objective To explore the relationship of neuron injury and its severity with the cause and the duration of convulsion Methods Patients were divided into 5 groups or 3 groups according to the causes of convulsion or duration of convulsion in children The levels of neuron specific enolase(NSE) and nitrogen monoxide and nitricoxide synthase(NO/NOS) in serum and cerebrospinal fluid(CSF) were tested by ELISA and spectrophotography at different time points after convulsion in children Results The levels of NSE and NO/NOS in serum and CSF of all objective groups except the febrile convulsion group were apparently higher than those in control group( t =15 4～47 7, P

Aim To explore the effects of Nimodipine(NDP) treatment on the expression of neural cell adhesion molecule(NCAM) after the ischemic brain injury in rats.Methods One hundred male Wistar rats(180~220g) were randomly divided into four groups:sham operation control group(SOCG,n=10),cerebral ischemia control group(CICG,1,3,7 d,n=30),high and low dose Nimodipine treatment group(H-NTG,L-NTG,1,3,7 d,n=10).Their middle cerebral arteries of CICG and NTG were blocked by filament forming brain injured,the NTG groups were treated with NDP(0.5 mg?kg-1 and 1mg?kg-1),respectively.and then,their cerebral blood flow was reperfused.Their blood vessel shape of cerebri surface was observed and the expression of NCAM was determined,after neurologic impairment(NIP) was scored and regional cerebral blood flow(RCBF) was surveyed,respectively.Results 3 d,7 d PO2 of H-NTG were higher than those of CICG(P

Objective To investigate the expressions of heat shock protein(HSP)90α and HSP90β in peripheral blood mononuclear cells (PBMC) in myasthenia gravis (MG) children before and after glucocorticoid (GC) treatment,and normal control groups.Methods Fresh bloods were collected from 20 cases of children with MG before and after treatment and 19 healthy children.PBMCs were isolated,followed by measurement of the expression levels of HSP90α and β by immunocytochemistry,and HSP90α and β mRNAs by reverse transcription and polymerase chain reaction (RT-PCR).Results The positive cell ratio of HSP90α andβ of MG children before and after of GC treatment was significantly higher than control groups (P ＜ 0.05),and their mRNA expression levels was higher than control groups (P ＜ 0.05).HSP90β in MG children after GC treatment was mainly expressed in the nucleus(P ＜ 0.05).Conclusions HSP90α and β in PBMC of MG children before and after GC treatment were significantly higher than those of normal control groups.HSP90β in MG Children after GC treatment was significantly increased.The present results suggest HSP90β promote GC receptor binding and enhance GC transportation,which promotes and strengthens the physiological and pharmacological effects of GC to improve the clinical symptom of MG children.

Febrile seizures ( FS ) is a common convulsive disorder in infants and young children. It is clinically classified into simple febrile seizures(SFS)and complex febrile seizures(CFS). Although intensively investigated,it remains controversial on the etiology,pathogenesis,treatment,long-term prognosis of FS,even the definition itself is still under debate. This paper briefly reviews recent advances on the underlying mechanisms of FS,including involvement of genetic factors,role of ion channels,and immunologic and neurotransmitter dysreg-ulation. We also gathered some new insights on the treatment and prevention of FS,aiming to improve our under-standing of FS.

Objective To explore the changes of cytokines in myasthenia gravis children and the effect of glucocorticoid on the serum levels of them.Methods Forty cases of myasthenia gravis children were the observation group which was divided to group one (pre-glucocorticoid therapy)and group two (post-glucocorticoid therapy),and 20 cases of healthy children in the same period as the normal control group.The serum levels of cytokines INF-γ,TGF-β1,IL-10 and IL-18 of the observation group one and two and the normal control group were detected by ELISA and were compared between the observation group one and the normal control group and the observation group one and two.Results The serum levels of cytokine INF-γand IL-18 were higher and IL-10 and TGF-β1 were lower in the observation group than in the normal control group,the differences were statistically significant (t =4.45 ~16.72,P <0.01 ).Significant difference of INF-γ,TGF-β1 and IL-18 was found between the observation group one and two (t =8.12 ~10.68,P <0.01)and the sera level of IL-10 had no significant difference (P >0.05).Conclusions Cytokines INF-γ,TGF-β1,IL-10 and IL-18 are involved and probably play different roles in the pathogene-sis of myasthenia gravis in children;Glucocorticoid could affect the secretion of cytokines IFN-γ,TGF-β1 and IL-18 of myasthenia gravis children,which would ultimately to achieve the aim of interfering and con-trolling the clinical symptom of myasthenia gravis in children.
