Disability evaluation of 204 cases of children with brain injury in road traffic accidents / 法医学杂志

OBJECTIVE@#To study the types, characteristics and common complications as well as disability assessment for the children with craniocerebral injury in the road traffic accidents.@*METHODS@#Data from 204 cases of children with cranio-injury in road traffic accidents were collected and were statistically analyzed according to the location injured, complication, the type of complication and the severity of disability.@*RESULTS@#There were 64 cases of simple diffuse primary craniocerebral injury, 80 cases of simple local primary cranio-injury, 24 cases of diffuse secondary craniocerebral injury and 36 cases of local secondary cranio-injury. The main complications included traumatic epilepsy (14, 6.9%), traumatic cerebral infarction (9, 4.4%), traumatic hydrocephalus (7, 3.4%) and traumatic mental disorder (5, 2.5%).@*CONCLUSION@#Among the children with cranio-injury due to road traffic accidents, simple primary cranio-injury was the most common result, whereas the traumatic epilepsy and traumatic cerebral infarction were the major types of complications. The assessment criteria for body impairment of the children with craniocerebral injury in the road traffic accidents should be broadened accordingly, with addition of certain specific items for children.

Epidemiological research and analysis on the impaired person in road traffic accident in Chengdu area / 法医学杂志

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.

The intelligence characteristics of the head traumatic children / 法医学杂志

OBJECTIVE@#To explore characteristics of the head traumatic children's intelligence.@*METHODS@#The authors investigated 43 head trauma children and 50 normal children, using Wechser Intelligence Test (C-WISC). Data were analyzed by SPSS10.0 on computer.@*RESULTS@#Head trauma children had lower FIQ, VJQ, PIQ than normal children. Pervaded head trauma has more contribution to the damage of the children's intelligence.

Analysis on body impairment assessment upon 447 thoracolumbar, spinal injury cases in traffic accidents / 法医学杂志

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.

A case-crossover study on road traffic injury / 中华流行病学杂志

<p><b>OBJECTIVE</b>To explore the risk factors of road traffic injury (RTI), and to provide evidence for stretagy development on the prevention and control of RTI.</p><p><b>METHODS</b>Case-crossover study was used. 402 drivers were face to face interviewed by specially designed questionnaire including the items as drinking alcohol before driving, onset anger scale (OAS), anxiety/irritation, Stanford sleepiness scale (SSS), vehicle breakdown, carelessness, violating the rules on right of way and traffic signs when driving. Tables related to case-control study on 1:1 matching was used for single factor analysis, and conditional logistic regression was used for multifactor analysis.</p><p><b>RESULTS</b>The risk factors that were associated with RTI including high OAS (OAS = 5-7, OR = 114.88, 95% CI:4.29-3074.86), violating the rules on right of way (OR = 46.96, 95% CI:12.74-173.11), violating traffic signs when driving(OR = 24.57, 95% CI: 8.69-69.45), carelessness (OR = 14. 54,95% CI: 6.85-30.86), unsafe distance between vehicles( OR = 14.30,95% CI: 3.68-55.60), wrong judgement (OR = 14.67,95% CI:4.88-44.10), vehicle breakdown (OR = 8.57, 95% CI: 1.38- 53.27) and improper measure ( OR = 8.46, 95% CI: 2.46-29.14) etc.</p><p><b>CONCLUSION</b>Improper driving behaviors, abnormal psychological status and driving skills of drivers were related to RTI, suggesting that it was necessary to carry out continous traffic security education to the drivers.</p>

Sequence polymorphisms of the mitochondrial DNA control region in 100 Chengdu Hans in China / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To study the genetic polymorphisms of the mitochondrial DNA (mtDNA) control region in Chengdu Han population.</p><p><b>METHODS</b>Sequence polymorphisms of the mtDNA control region, hypervariable regions I and II from 100 unrelated Chinese Hans were determined by PCR and direct sequencing.</p><p><b>RESULTS</b>Sequences of 404 nucleotides for hypervariable region I and 379 nucleotides for region II were obtained. Ninety-two and fifty variable sites were revealed in region I and region II respectively as compared to the reference sequence, and a total of 97 different genetic patterns from both the regions I and II were determined. The probability of identity was estimated at 1.84% for region I, 1.94% for region II, and 1.18% for both the regions.</p><p><b>CONCLUSION</b>These results suggest that sequence polymorphism of mtDNA control region would be very useful in forensic practice as a marker for individual identification.</p>
