College Students’Cognition of Internet Accidental Injury Insurance:A Case Study of Guangdong Province

To explore college students'understanding and satisfaction of internet accidental injury insurance,and to analyse the factors influencing college students'awareness and satisfaction of internet accidental injury insurance.836 college students in Guangdong Province were selected by stratified random sampling.They were investigated with the self-designed questionnaire"College Students'Cognition of Internet Accidental Injury Insurance(CSCIAII)".29.67%,52.18%,10.13%and 8.02%of the college students didn't know,knew a little,knew relatively well and knew very well about internet accidental injury insurance,respectively.The percentage of college students who were very satisfied with the internet accidental injury insurance,thought the internet accidental injury insurance basically met their own needs,think it was acceptable but needed to be improved,did not agree with and were not satisfied with it at all were 9.55%,16.82%,47.73%,11.82%and 14.09%,respectively.College Students’awareness of insurance is weak,and they do not pay enough attention to accidental injury insurance.The design,publicity and sale strategies of internet insurance products may be important factors affecting college students'understanding and satisfaction with internet accidental injury insurance.

Prevention and control of serious trauma and accidental injury in China: Timely but difficult

Serious trauma and accidental injury are the leading causes of death among people younger than 45 years old in China. Thus, the prevention and control of serious trauma and accidental injury are important for reducing these deaths. The concept is timely but difficult. Here, we review the current state of serious trauma and accidents in China and other countries, focusing on road accidents, and provide our personal perspectives and suggestions on how to prevent and control these serious injuries in China.

Radiological findings of February 2023 twin earthquakes-related spine injuries

BACKGROUND The February 6,2023,twin earthquakes in Türkiye caused significant structural damage and a high number of injuries,particularly affecting the spine,which underscores the importance of understanding the distribution and nature of vertebral injuries in disaster victims.AIM To investigate the distribution of radiological findings of vertebral injuries in patients referred to a major tertiary center during the February 6,2023 twin earthquakes in Türkiye.METHODS With the approval of the institutional ethics committee,1216 examinations of 238 patients transferred from the region to a tertiary major hospital after the twin earthquakes of February 6,2023,were retrospectively analyzed for spine injuries.RESULTS Spine computed tomography(CT)scans were performed in 192 of 238 patients with a suspected spinal injury,42 of whom also had an magnetic resonance imaging(MRI).In 86 of 192 patients(44.79%;M:F=33:53)a spinal fracture was detected on CT and in 33 of 42 patients(78.57%;M:F=20:13)a spinal injury was found on MRI.Of the 86 patients in whom vertebral injury was detected,fractures were detected in the Denis-B group in 33,Denis-C in 4,Denis-D in 20 and Denis-E in 11 patients.Among the vertebral bodies:40"compression fractures",17"burst fractures",5"translational dislocation fractures",5"flexion-distraction fractures"and 58"prolonged forced fetal posture fractures"were detected.In addition,isolated transverse or spinous process fractures were found in eighteen vertebrae.CONCLUSION Our study highlights the prevalence and diverse spectrum of spinal injuries following the February 6,2023 twin earthquakes in Turkey underscoring the urgent need for effective management strategies in similar disaster scenarios,and emphasizing the"prolonged forced fetal posture"damage we encountered in earthquake victims who remained under the collapse for a long time.

BRAIN INJURY BIOMECHANICS IN REAL WORLD VEHICLE ACCIDENT USING MATHEMATICAL MODELS

This paper aims at investigating brain injury mechanisms and predicting head injuries in real world accidents. For this purpose, a 3D human head finite element model （HBM-head） was developed based on head-brain anatomy. The HBM head model was validated with two experimental tests. Then the head finite element（FE） model and a multi-body system （MBS） model were used to carry out reconstructions of real world vehicle-pedestrian accidents and brain injuries. The MBS models were used for calculating the head impact conditions in vehicle impacts. The HBM-head model was used for calculating the injury related physical parameters, such as intracranial pressure, stress, and strain. The calculated intracranial pressure and strain distribution were correlated with the injury outcomes observed from accidents. It is shown that this model can predict the intracranial biomechanical response and calculate the injury related physical parameters. The head FE model has good biofidelity and will be a valuable tool for the study of injury mechanisms and the tolerance level of the brain.
