Objective:to collect and summary mental disturbance caused by severe craniocerebral injury Method:to compare 150 cases of mental disturbance caused by severe craniocerebral injury with those (20 cases) with similar injury but without mental disturbance Result:1) The rate of those with mental disturbance in patients with severe craniocerebral injuries was 20 8% The rate of that in all patients of head injury was 5 2% 2) 107 of our sample (71 3%, 107/150) had sub-arachnoid hemorrhage 27 had fracture at the base of skull 3) Compared with those without mental disturbance, the occurrence of mental symptoms closely related to severity of injury 4) Delirium was the early symptom, while memory deficiency and affective disorder were common on the later stages Conclusion:Patients with brain contusion with subarachnoid hemorrhage are more likely having mental disturbance

Objective To explore the application of the model centering on organ system teaching in experimental diagnostics and evaluated its teaching effect.Methods A total of 185 clinical medical undergraduates of grade 2012 and 2013from School of Basic Medical Science in Tianjin Medical University joined the integrated curriculum of laboratory diagnostics for liver disease (abbreviated as integrated group).All of the teachers from varied professional fields were reconstituted into integrated teaching group.Training lecture was unified according to the new integrated teaching material.In order to make a contrast,180 clinical medical undergraduates of the grade 2010 and 2011 were involved in traditional laboratory diagnostics curriculum (abbreviated as traditional group).The results of terminal test of the integrated group and traditional group were analyzed with SPSS 21.0 software and Excel 2007.Glossary items,multiple choice,were indicated by scoring rate,and the objective items and subjective items total scores were indicted by real scores.Results Significant difference was found in the scoring rate of the glossary items,objective items,subjective items and the total scores between the two groups (P＜0.01).The records of students were [75.00％ (50.00％,100.00％)],(72.28 ± 22.63),(90.70 ± 22.36),(79.96 ± 18.59) in the integrated group and [66.67％ (33.33％,83.33％)],(61.43 ± 28.85),(72.92 ± 22.14),(69.10 ± 17.95) in the traditional group.The scoring rate in the integrated group was higher than that in the traditional group (P＜0.01).But the records of multiple choice were [100.00％ (0.00％,100.00％)] in the traditional group and [66.67％ (66.67％,100.00％)] in the integrated group.Conclusions The model centering on organ system teaching model is much more reliable and it may improve the teaching quality.
