RESUMO
Objective The researchers aimed to investigate the feasibility and efficiency of cultivating ICU talents in nursing profession of higher vocational college.Methods On the basis of the nursing profession in college,the ICU direction was established in the talent cultivation mode of higher vocational college in 2007,2008 and 2009.And the students majored in ICU specialty were cultivated by the joint effort of college and the affiliated hospitals,and cultivate more professional talents of narrower direction.The feedback of teaching,the rate of employment,and the comprehensive evaluation of the graduates' quality from employers were informed by using the self-developed questionnaire.Results The rate of passing Chinese Licensure Examination for Nurse and the rate of employment were 100 percent.The students were satisfied in studying in this specialty,the graduates majored in ICU specialty were employed by the tertiary hospitals,and much higher evaluation were given by the employers.Conclusions To establish the ICU specialty in nursing profession of higher vocational college has benefits for the professionalization and specialization of nursing,which builds a solid ground for cultivating specialized ICU nurses in the hospital.
RESUMO
Objective:To observe dynamic change of phosphorylated tau protein and non phosphorylated tau protein in axon and explore whether GSK3 in serum were related with phosphorylated tau protein in brain of EAE mice.Methods: Mice were randomly divided into six groups:EAE group of acute stage,EAE group of paralytic stage,EAE group of remission stage,control group of acute stage,control group of paralytic stage,control group of remission stage,each group had twelve mice.EAE model were constructed by MOG35-55 peptides in EAE group, the saline was used in control group.The nerve function scores and incidence were observed and compared.We observed degree of brain inflammation by HE staining and measured axons which contained two kinds of tau protein by immunohistochemistry.GSK3 in serum was tested to find correlation with phosphorylated tau protein in brain by ELISA method.Results:Nerve function scores in EAE group were higher than control group.The degree of inflammation damage was more serious in EAE group than control group,gradually enhancing with time.Phosphorylated tau protein in brain gradually increased before mice paralyzing(P<0.01),but it decreased when symptom relieved(P<0.01).GSK3 in serum were correlated with phosphorylated tau protein in brain(r=0.9326,P<0.01),linear regression equation:Y=2.950+0.418X.Conclusion:Phosphorylated tau protein in brain are correlated with axon damage and GSK3 in serum could indirectly reflect axon damage in brain.
RESUMO
To investigate the correlation between LCN 2 or CXCL10 and experimental autoimmune encephalomyelitis(EAE),and the effect of Fluoxetine in EAE mice.Methods: Mice were randomly divided into four groups: control group, EAE group, intervention group and fluoxetine group , each group included twenty mice.EAE model were constructed with MOG35-55 in the intervention group and fluoxetine group ,following ultraviolet (UV) (280-320 nm) irradiation.Mice in fluoxetine group were given fluoxetine (10 mg/kg) by daily gavage since immunized ,and the saline was used in the control group ,intervention group and EAE group in the same way and same time.The drug/saline was continuously administered from the immunization to the day mice were sacrificed.The mean attacked time ,the nerve function grades and the incidence were observed and compared.We observed brain pathological changes by HE staining and immunohistochemistry;CXCL10 were tested by ELISA method ,and compared among the four groups.Results:The mean attacked time ,the nerve function grades and the incidence in the fluoxetine group were lower than those in the intervention group and EAE group ,there were significant differences between two groups (P<0.05),in the intervention group were lower than those in the EAE group ,there were significant differences between two groups ( P<0.05 ).Fluoxetine treated EAE mice showed decreased degree of inflammatory infiltration;the mean rank of positive cells lower in the fluoxetine group than those in the EAE group,the differences were significant between two groups ( P<0.05 ).The expression of CXCL10 in the peripheral blood plasma of fluoxetine group were lower than those in the EAE group ,there were significant differences between two groups ( P<0.05 ).Levels of LCN2 expression were correlated with those of CXCL 10 in the EAE group.Conclusion: LCN2, CXCL10 are correlated with the pathogenesis of EAE.Fluoxetine could alleviate clinical symptoms of EAE and alleviate the morbidity of EAE.
RESUMO
@#Reversible cerebral vasoconstriction syndrome (RCVS) usually occurs during normal pregnancy or a few days after delivery. The gold standard of diagnosis is the reversibility of cerebral vascular constriction confirmed by digital subtraction angiography (DSA). In this article, we descried the clinical and imaging features of one RCVS case proved by repeating DSA, and discussed the probably pathophysiological mechanisms.
