目的 :观察快动眼睡眠 ( rapid eye movement sleep,REMS)剥夺大鼠行为的改变及其下丘脑诱生型一氧化氮合酶( i NOS) m RNA表达的时相变化。方法 :小站台水环境法剥夺大鼠睡眠 2 4、4 8、72 h后 ,用旷场实验 ( open field test,OFT)观察大鼠主动行为的变化 ,同时用半定量逆转录聚合酶链反应 ( RT- PCR)检测其下丘脑 i NOS m RNA的表达。结果 :睡眠剥夺2 4、4 8h组大鼠的旷场实验得分较非剥夺组高 ( P<0 .0 1) ,剥夺 72 h后降低 ;睡眠剥夺 2 4 h及 4 8h组 i NOS m RNA的表达量无显著变化 ,但剥夺 72 h组 i NOS m RNA的表达量大幅度增加 ( P<0 .0 1)。结论 :内源性一氧化氮 ( NO)增加可能是睡眠剥夺后机体精神行为变化的重要原因 ,高水平的

Objectives:To examine the relationship between defense style and mental health among divers in the navy. Methods:A total of 414 divers were assessed in group on the Defense Style Questionnaire (DSQ) and Cornell Medical Index(CMI). Rank correlation coefficient was computed for evaluating relationship between scores on the questionnaires. Results:Defense style of divers was highly correlated with mental health status; divers with poorer mental health condition tended to adopt immature defense style. Conclusion: Divers’ mental health bears significant relationship to their defense style of coping.
