Objective To establish the preferable puberty pathological aggression animal model.Methods The experimental models were established towards puberty rats by frustration test of non-reward and instigation test.Rat models were tested for specificity using open-field test,saccharine test,elevated plus-maze(EPM)and olfactory sensibility.Results ①Compared with normal aggression(52.5±5.36)and control group(8.83±1.34)in total aggressive times,the pathological aggression group(101.17±2.85)increased significantly(P<0.01);②Some behavior items of each model group were moderately or hishly correlated to total score(r=0.379～0.929);③There was a significant difference between pathological aggression group and normal aggression group in the numbers of attack toward vulnerable-body regions,persistence attack after intruder displayed submissive and hish attack/threat ratios(P<0.01);④The pathological aggression group did not show depression,anxiety and olfactory disorder,except for space cognitive function(P>0.05).However,the normal aggression group displayed obvious depressive mood.Conclusion Each behavioral index matches the criteria of pathological aggression model.Meanwhile,it also excludes other factors of disturbing the specificity of the model.It suggests this model may be preferable puberty pathological aggression animal model.

CBS(Case Based Study)is a new teaching method,which is based on the case given.It requires students to answer questions according to the case. In the teaching,the students who are divided into groups,seek for resolvent by themselves. They should combine the information provided in the case,find the key answer and the relationship.The students gain the knowledge by reviewing and studying in the textbook,then analyse and solve questions with them. The application of CBS could make knowledge more relatively and systematic, moreover,it also make study more actively and initiatively.

Objective To explore the changes and the clinical relevance of plasma p-selectin (PS) and vascular endothelial cell function in patients with carotid stenosis (CS) before and after carotid artery stenting (CAS). Methods The plasma levels of PS, yon willebrand (vWF) and endothelin-1 (ET-1) before CAS and 1hour,6 hours,24 hours,2 months after CAS in 67 patients with carotid stenosis and 54 cases of TIA with negative result from cerebral angiography were measured. The patients of the therapy group were further divided into group A and group B according to complexity of CAS. The plasma levels of PS and vWF were determined by enzyme linked immunosorbent assay,and the level of ET-1 was measured by radioimmunoassay. Results The plasma levels of PS,vWF and ET-1 all increased in the patients group after CAS. In the therapy group,the level of PS reached peak value (29.23 ± 6.98) ng/ml 1 hour after CAS, and the levels of vWF and ET-1 reached peak value (119.63 ±16.75) %, (79.71 ± 9.78) ng/L 6 hour after CAS. In therapy group, there was significant difference in the levels of PS and ET-1 between each time points after CAS and before CAS (P＜0.05,P ＜0.01 respectively). There was significant difference in the level of vWF between 1 hour, 6 hours, 24 hours after CAS and before CAS (P ＜ 0.05 orP ＜ 0.01). There was significant difference in tihe levels of PS 1 hour after CAS and ET-1 at 6 hours after CAS (P ＜0.05) ,and in the level of vWF at 1 hour,6 hours after CAS between control group and therapy group (P ＜0.01).There was significant difference in the level of vWF at every time point after CAS (P ＜ 0.05 or P ＜ 0.01), and in the level of ET-1 at 1 hour,6 hours,24 hours between A group and B group(P ＜0.05 or P ＜0.01). Conclusions PS, vWF and ET-1 were activated to some extent and related to pathological changes degree and complexity of CAS. Monitoring these biological indexes after CAS maybe of great value in predicting risk, evaluating clinical therapy and judging prognosis.

Objective: To investigate the antihypertensive time-effect and dose-effect features of Sancao jiangya decoction(SCD).Methods: The blood pressure of spontaneously hypertensive rats at different time points were measured after treatment with Sancao jiangya decoction of low,middle,high concentration by tailartery blood pressure measurement for conscious rats.Results: The blood pressure was decreased at 2 hours after drug taken,there were significant dose-effect relationship between the antihypertensive effect and the low,middle,high dose.At 4h after drug taken,the high,middle dose had dose-effect correlation,but the low-dose had no antihypertensive effect.Further research on the middledose shows that the blood pressure reduced at 1h after drug taken,and the stable antihypertensive effect was keeping during 1-4h,the blood pressure began to rise at 6h,and got back to the level before drug taken at 8h.Conclusion: To choose the Middle-dose(10.4g crude drug/kg body weight) and 2h after drug taken is appropriate for SCD's use.This result laid a substantial foundation for further research on effects evaluation and mechanism of antihypertensive medicine.

BACKGROUND: The protein kinase C (PKC) family consists of 3 groups of PKCs, namely the conventional PKC (cPKC), atypical PKC and novel PKC.Accumulating studies conducted in recent years have suggested that PKCs may play important roles in the development of cerebral ischemic/hypoxic preconditioning ( I / HPC ).OBJECTIVE: To observe membrane translocation of hypoxia-activated cPKC isoforms(α, βⅠ, βⅡ and γ) at cellular levels in a cell hypoxia model.DESIGN: Randomized block design.SETTING: Department of Neurobiology, College of Basic Medical Sciences,Capital University of Medical Sciences.MATERIALS: The experiment was completed at the Neurobiological Cell Culture Laboratory of Capital University of Medical Sciences in May 2004.Human neuroblastoma cells with the properties of neurons were maintained and passaged in this laboratory.METHODS: The activation of cPKC isoforms under hypoxic condition and changes of cPKCα, βⅠ, βⅡ and γ membrane translocation(an indicator of PKCs activation) in SH-SY5Y neuroblastoma cells in response to hypoxia (1% 02, 5% CO2 and 94% N2) for 0 to 24 hours were observed using SDS-PAGE, Western blotting and immunocytochemistry.MAIN OUTCOME MEASURES: Effect of sustained hypoxia on cPKC membrane translocation in human neuroblastoma cells was observed with SDS-PAGE, cPKC Western blotting, and immunocytochemistry.RESULTS: cPKCα, βⅠ and βⅡ membrane translocation were increased significantly ( P ＜ 0.05 ) in a time-dependent manner in response to hypoxic exposure, and the increase of cPKCβⅠ was more evident( P ＜ 0. 001 ) after 4hours of hypoxic exposure, whereas no cPKCγ was detected in SH-SY5Y neuroblastoma cells either under normoxic or hypoxic condition. The results suggested that all cPKC isoforms, epically cPKCβⅠ, could be activated by sustained hypoxia, and the absence of cPKCγ in SH-SY5Y neuroblastoma cells may be relevant to the loss of specific biological features of the cultured cells.CONCLUSION: Sustained hypoxia activates the isoforms of cPKCα, βⅠ and βⅡ in human neuroblastoma cells and induces their membrane translocation.cPKCγ isoform may not exist in human neuroblastoma cells, or the cells has lost certain biological characteristics.
