ABSTRACT
OBJECTIVE@#To investigate changes of brainstem auditory evoked potential (BAEP) in patients with brain concussion.@*METHODS@#Nineteen patients with brain concussion were studied with BAEP examination. The data was compared to the healthy persons reported in literatures.@*RESULTS@#The abnormal rate of BAEP for patients with brain concussion was 89.5%. There was a statistically significant difference between the abnormal rate of patients and that of healthy persons (P<0.05). The abnormal rate of BAEP in the brainstem pathway for patients with brain concussion was 73.7%, indicating dysfunction of the brainstem in those patients.@*CONCLUSION@#BAEP might be helpful in forensic diagnosis of brain concussion.

OBJECTIVE@#To analyze epidemiological characteristics of road traffic accidents that resulted in injuries in Chengdu area, to find out the cause and to provide scientific a base for accident prevention.@*METHODS@#Appraisal data of the injured in road traffic accident from January 2003 to October 2006 were re-examined. Detailed statistics were made which include gender, age, transportation mode, person types, the accident date and day, and location.@*RESULTS@#Six thousand three hundred and sixty four cases involving road traffic accident were analyzed. Among the injured, male to female ratio was 1.84:1, and the age group of 18-50 were the largest proportion (66.34%). Bicyclists, motorcyclists and pedestrians made up 80.90% of the injured persons. Different age groups, different genders and those who were injured in different regions varied greatly in terms of transport modes they employed. In terms of injured parts, lower limb injury took up the highest proportion (39.49%), with cranium & cerebrum ranking second (22.77%).@*CONCLUSION@#Different approaches and measures shall be taken in regard to different age groups, different regions, different times and different transport modes, and corresponding policies shall be adopted.

OBJECTIVE@#To discuss the relation between degree of body impairment and that of thoracolumbar spinal injuries resulting from road traffic accidents, and sum up the experiences in body impairment assessment and its regularity.@*METHODS@#For comprehensive body impairment assessment, 477 cases of thoracolumbar spinal injuries in road accidents have been sorted out, reassessed and rediagnosed. In addition, analyses have been undertaken about their treatment, the assessment of the degree of their thoracolumbar dysfunction,nerve dysfunction and the relations between injuries and sequelaes.@*RESULTS@#The analyses show that the degree of thoracolumbar dysfunction and that of the post-injury nerve dysfunction don't necessarily depend on the quantity and degree of spinal injuries. However, the position suffering from the thoracolumbar spinal injuries has an immense impact on the thoracolumbar dysfunction, and the nerve impairment result mainly from the T1-1L spinal injuries. The research also shows that there has been a high misdiagnosis rate in hospital about the spinal injuries.@*CONCLUSION@#In body impairment assessment, the cause and effect relations between the injury and degree of injury extent should be analyzed, the injury extent should be employed as principal evidence, and the degree of spinal dysfunction should be taken into greater consideration.
