RÉSUMÉ

Objective:To explore the application effects of the mode of "Multidisciplinary integration, Doctors & patients co-teaching, Simulated practice" in the teaching of spinal surgery.Methods:A total of 64 eight-year program clinical medical students who practiced in Peking Union Medical College Hospital in 2021 were taken as research objects and randomly divided into experimental group ( n=33) and control group ( n=31). The experimental group received the new teaching mode of "Multidisciplinary integration, Doctors & patients co-teaching, Simulated practice", and the control group received regular teaching mode. At the end of teaching, the teaching effects were evaluated from several aspects, including the scores of theoretical examinations, anatomical marks identification tests, and anonymous questionnaires. SPSS 22.0 software was used for paired t-test and two independent-samples t-test. Results:The theoretical test scores [(51.25±6.99) points] and anatomical structure identification scores [(37.56±1.83) points] of the experimental group were higher than those of the control group [(42.46±6.13) points and (30.37±3.46) points], and the differences were statistically significant ( P<0.001). The effective recovery rate of the questionnaire was 100%. The results of the questionnaire showed that the experimental group was significantly higher than the control group in terms of teaching attractiveness, attention, learning interest, learning efficiency, anatomical identification ability, problem-finding and problem-solving ability and overall teaching method satisfaction ( P<0.05). Conclusion:The teaching mode of "Multidisciplinary integration, Doctors & patients co-teaching, Simulated practice" can effectively improve students' theoretical knowledge, learning interest, learning efficiency, operation proficiency and problem-finding and problem-solving ability, which is worth promoting.

RÉSUMÉ

Aim To observe histopathological changes of hippocampus after acute epilepsy induced by penty-lenetetrazole (PTZ)in rats.Methods Five groups as control group,PTZ-induced 24 hours(h)group,PTZ-induced 72 hours group,PTZ-induced 1 20 hours group and PTZ-induced 1 44 hours group were designed.PTZ (64 mg·kg -1 )was administered with a single intrap-eritoneal injection for generalized tonic-clonic sei-zures in the current experiment.Control and PTZ trea-ted animals were sacrificed after specific time points. Brain was dissected out and then evaluated for neuro-pathological changes using Nissl staining and immuno-histochemical technique.Results In this study PTZ-induced hippocampal neuron status apoptosis occurred at 24 hours and was sustained for 1 44 hours after status epilepticus.Whereas,activated caspase-3 and AIF ap-peared at 24 hours and were sustained for 1 44 hours af-ter status epilepticus.Conclusion The results of this study show that the significant histopathological chan-ges of hippocampus appear in the vicinity of 1 20 hours after intraperitoneal injection of pentylenetetrazole.
