This article discusses the relevant factors which influence the assessment and diagnosis of personality disorder, especially the relationships between personality disorder and personality,personality disorder and the axis I conditions in the Diagnostic and Statistical Manual of Mental Disorders (DSM) system and its particularity of assessment. Such discussion helps to improve the clinical worker's comprehension to the psychopathology, personality disorder and their relationships.

Taking global minimum essential requirements(GMER)as standard,school of basic medical science in Wuhan University paid more attention to the cultivation of students' professional skills, innovation ability and communication ability. ‘Response to injury’integrated course was carried out. Based on the immunology,this course involves pathology and pathophysiology and explores the mecha-nism of the diseases' diagnosis and treatment. It took small classes,bilingual education,literature read-ing ,experiments and discussions in various forms . This reform aimed to improve the immunology , pathology and pathophysiology teaching and make our medical education meet the process of globalization.

Objective To evaluate the role of ERK1/2 signal transduction pathway in sevoflurane postconditioning-induced reduction of oxygen-glucose deprivation(OGD)injury in rat hippocampal slices.Methods Male adult SD rats weighing 80-100 g were anesthetized with ether and decapitated.The hippocampi were removed and sagittally sliced(400μm thick)and placed in artificial cerebrospinal fluid(aCSF)aerated with 95％ O2-5％CO2.Fifty hippoeampal slices were randomly divided into 5 groups(t =10 each):OGD group; 4％ sevoflurane postconditioning group(group Sevo); PD98059(specific inhibitor of ERK)group(group PD); dimethyl sulfoxide (DMSO)group; 4％ sevoflurane postconditioning + PD98059 group(group SPD).OGD was induced by incubating the slices in glucose-free aCSF aerated with 95％ N2-5％ CO2 for 15 min in group OGD.The hippocampal slices were perfused with aCSF saturated with 4％ sevoflurane for 30 min after OGD was induced in group Sevo.The hippocampal slices were perfused with aCSF containing PD98059 50 μmol/L for 10 min after OGD was induced in group PD.The hippocampal slices were perfused with aCSF containing DMSO 1 mol/L for 10 min after OGD was induced in group DMSO.The hippocampal slices were perfused with aCSF containing PD98059 50 μmol/L and aerated with 4％ sevoflurane for 30 min after OGD was induced in group SPD.The hippocampal slices were then perfused with plain aCSF for 1 h again in all the groups.The electrophysiological technique was used 1o record the amplitude of orthodromic population spike(OPS)in the stralum pyramidale of the CAI region.TTC staining was used to determine the degree of tissue injury.Results Compared with group OGD,the recovery amplitude and rate of OPS were significantly increased,and the degree of tissue injury was significantly decreased in group Sevo(P ＜0.01),while no significant change was found in each parameter in the other three groups(P ＞ 0.05).Compared with group Sevo,the recovery amplitude and tale of OPS were significandy decreased,and the degree of tissue injury was significantly increased in groups PD,DMSO and SPD(P ＜ 0.01).Conclusion ERK1/2 signal transduction pathway is involved in sevoflurane postcondilioning-induced reduction of OGD injury in tat hippocampal slices.

ObjectiveTo investigate the effects of diazoxide pretreatment on expression of phosphatidylinositol 3-kinase(PI3K) mRNA and protein serine/threonine kinase(Akt) mRNA in rat myocardial microvascular endothelial cells exposed to hypoxia-reoxygenation (H/R).MethodsThe SD rat myocardial microvascular endothelial cells were cultured.The cells were seeded in 96-well plates ( 100μd/hole) or in 6 cm diameter dishes (2 ml/dish) with the density of 1 × 106/ml and randomly divided into 4 groups ( n =25 each):normal control group (group C),H/R group,diazoxide pretreatment group (group DZ) and diazoxide pretreatment + 5-hydroxydecanoate (5-HD,a mitochondrial ATP-sensitive potassium channel blocker) group (group DZ + 5-HD).The cells were exposed to 2 h hypoxia followed by 2 h reoxygenation.Diazoxide 100 μmol/L and diazoxide 100 μmol/L + 5-HD 100 μmol/L were added to the culture medium 2 h before hypoxia in groups DZ and DZ + 5-HD respectively.The cell viability,apoptotic rate and expression of PI3K mRNA and Akt mRNA were detected at the end of reoxygenation.ResultsCompared with group C,the cell viability was significantly decreased,while the apoptotic rate increased and expression of PI3K mRNA and Akt mRNA up-regulated in group H/R (P ＜0.05 or 0.01).Compared with group H/R,the cell viability was significantly increased,while the apoptotic rate decreased and expression of PI3K mRNA and Akt mRNA up-regulated in group DZ (P ＜ 0.05 or 0.01).5-HD could inhibit diazoxide pretreatment-induced changes mentioned above (P ＜ 0.05 or 0.01 ).ConclusionDiazoxide pretreatment can reduce H/R injury by promoting PI3K gene and Akt gene transcription through activation of mitochondrial ATP-sensitive potassium channels in rat myocardial microvascular endothelial cells.

ObjectiveTo explore the relationship between the mRNA and protein expressions of NIX and the pulmonary alveolus apoptosis following severe acute lung injury (ALI).Methods Rat models of severe collision injury on the chest were built.The mRNA and protein expressions of NIX in the alveolar cells at 6,12,24,48,72 and 96 hours after injury were detected using immunohistochemistry,immunoblotting and RT-PCR.Meanwhile,apoptosis of the alveolar cells was checked at different time points with Tunel assay.ResultsThe protein expression of NIX in the alveolar cells was observed both in experimental and control groups,which increased at 6 h post injury,peaked at 48 h and then declined till approaching the pre-injury level at 96 h.In the meantime,NIX showed a high expression both in the vascular endothelial cells (VECs) and the renal interstitial fibroblasts.The apoptosis of alveolar cells mainly presented in bronchi,blood vessel endothelium (BVE) and alveolar epithelium at 24 h post injury.The post-injury apoptosis rate of the alveolar cells was significantly higher than the pre-injury rate ( P ＜ 0.01 ),which reached the peak at 72 h and then decreased gradually.The changes of NIX protein in lung tissue showed a positive correlation with the apoptosis rate of alveolar cells after injury (r =0.303,P ＜ 0.01 ).ConclusionsThe up-regulated expression of NIX takes part in the pathophysiological process of apoptosis of the alveolar cells and shows consistency with the apoptosis rate change of the alveolar cells,as may be the molecular basis for apoptosis of the alveolar cells after ALI.
