危机干预对飞行事故后飞行员脑灰质体积的影响

Influence of Crisis Intervention for Gray Matter Volume Changes in Pilots Experienced Air Accident

【目的】探讨危机干预对飞行事故后飞行员脑灰质体积的影响。【方法】入组16例飞行事故后飞行员作为研究组和16例健康飞行员作为对照组,进行静息态脑功能数据采集,利用SPM5软件用基于体素的形态学方法处理静息态磁共振数据,对比两者的差异。而后对研究组人员进行危机干预,继而采集干预后飞行员脑功能数据,处理后与干预前数据进行对比。【结果】相比对照组,研究组事故后双侧额上回、额中回,双侧海马和双侧扣带回前部灰质体积减小。而相比研究组干预前,干预后飞行员双侧额上回、额中回,双侧海马灰质体积增大。【结论】飞行事故后飞行员的脑灰质体积相对正常飞行员缩小。危机干预后飞行员脑灰质体积相对干预前增大。

[Objective] To investigate the influence of crisis intervention for gray matter volume changes in pilots experienced air accident.[Methods] The subjects were 16 pilots experienced air accident and 16 healthy pilots.fMRI scanning were carried on the accident group （before and after crisis intervention） and control group.Gray matter volumes were analyzed using voxel-based morphometry （VBM） as implemented in SPM 5.Control group and air accident group after air accident and the data of air accident group before and after crisis intervention were compared to assess brain alterations.[Results]The gray matter volumes reduced in bilateral superior frontal gyrus,middle frontal gyrus,hippocampal and anterior cingulate cortex in air accident group compared to controls and increased in bilateral superior frontal gyrus,middle frontal gyrus,hippocampal in the air accident subjects after crisis intervention compared to the air accident subjects before crisis intervention.[Conclusion] The gray matter volumes reduced in pilots experienced air accident and increased after crisis intervention.
