目的基于功能核磁共振成像技术(fMRI),通过分析海员大脑默认网络的功能活动,探究长期出海对海员心理健康状况的影响.方法利用支持向量机方法进行心理健康评估分类器的训练,并对海员进行心理检测,进而将检测到的亚健康海员出海前后默认网络的激活程度以及中心节点的分布情况进行对比.结果亚健康海员出海后默认网络的激活程度明显减弱,且中心节点的分布也有显著变化.结论这些变化极有可能导致脑网络信息传输的紊乱,从而影响到相应的认知神经活动.该研究可及早发现海员的心理亚健康状况,为保障海员的身心健康,以及最终为建立一套有效的定量的海员心理健康评测体系和航海安全作业预警机制.

Objective To explore the effects of prolonged marine operation on the mental health status of seafarers,by using functional magnetic resonance imaging (fMRI) and through analysis of the function and activity of default mode network (DMN) of seafarers.Methods At first,the support vector machine algorithm was utilized to learn the unsupervised mental health assessment classifier,and physical checks were made for the detection of their mental health status.Several sub-health seafarers were screened out through health detection.Then,DMN activation and the distribution of DMN hubs among the sub-health seafarers were compared between the data obtained before going out to sea and after coming back from sea.Results When compared with the state of sub-health seafarers before going out to sea,the DMN activation of the seafarers after coming back from sea was significantly weakened,and the distribution of DMN hubs also changed significantly.Conclusions These changes might result in information transmission disorder,which could affect higher cognitive neural activity of the seafarers.This research could provide a valuable tool for early detection of subhealth status and mental health support of seafarers,and finally it might be beneficial for the establishment of an effective and quantitative mental health assessment system for the early warning of marine operations and the safety of seafarers.
