住院军人述情障碍特征与事件相关电位P300相关研究

Related research of the alexithymia characteristic and the event related potential P300 of hospitalized soldiers

目的:探讨综合医院住院军人述情障碍和事件相关电位P300特征,及两者的相关关系。方法:随机抽取解放军第91医院住院的86名军人作为研究组,选择某部80名健康军人作为对照组,两组均给予多伦多述情障碍量表(TAS-20)评定以及事件相关电位P300检测,并将结果进行统计分析。结果:研究组和对照组比较,研究组TAS-20总分及各因子分均高于对照组(P<0.05或P<0.01);研究组N2、P3波潜伏期(PL)延长,P3波幅(Amp)降低(P<0.01);相关分析发现,住院军人P300的N2、P3波潜伏期与TAS-20总分及各因子呈显著正相关(r=0.296~0.367,P<0.05),与P3波幅呈显著负相关(r=-0.317^-0.334,P<0.05)。结论:住院军人存在一定程度的述情障碍和认知功能损害,认知功能损害一定程度反映述情障碍水平。

Objective： To investigate the alexithymia characteristic and the event related potential P300 of the hospitalized soldiers in the polyclinic,and the relationship of the two. Method： Randomly selected 86 soldiers of the NO. 91. central hospital of P. L. A. as the research group,choose one 80 healthy men as the control group,two groups were given the Toronto alexithymia scale（ TAS-20） and the event related potential P300 tests,and the results were statistically analyzed. Results： The research group＇s TAS-20 total score and each factor score were higher than the other one.（ P〈0. 05 or P〈0. 05）. While the N2,P3 latent period（ PL） prolonged,P3 amplitude（ Amp） reduced（ P〈0. 01）. The correlation analysis found that N2 and P3 latent period of P300 showed significant positive correlation with the TAS-20 total score and each factor（ r = 0. 296 ~ 0. 367,P〈0. 05）,while significantly negative correlated with the P3 amplitude. Conclusion： Certain degree of alexithymia and cognitive impairment exists among the hospitalized soldiers and cognitive function damage can objectively reflect the level of alexithymia.
