摘要

研究目的：将心理生理性失眠（PPI）中的睡眠微观宏观结构（以循环交替模式（CAP）、睡眠纺锤波和超兴奋为微观结构）和睡眠特征（如睡眠阶段变量和心率为宏观结构）作为微观结构。方法：研究两个统计群体，每组20名参与者：良好睡眠者（GS）和心理生理性失眠患者（PPI）。进行一晚的睡眠多导睡眠图（PSG），并对每个参与者进行睡眠宏微观结构提取。循环交替模式由人工评分，其他结构由原始PSG的设备软件监控。分析方法被用来剖析结果。结果：研究结果表明：（a）心理生理性失眠的特征是CAP与睡眠良好者的差异，这与过度兴奋有关；（b）在微观结构方面，睡眠阶段更多的微结构导致更多的觉醒指数。（c）睡眠阶段的比例、睡眠潜伏期和心率作为睡眠宏观结构发生了显著变化。（d）在我们的研究中，PPI组和GS组在纺锤体长度上没有显著差异。结论：将所有睡眠障碍，尤其是PPI、CAP变量、EEG觉醒和睡眠纺锤波作为微观结构和总睡眠时间、睡眠潜伏期、清醒次数、REM持续时间，和心率作为宏观结构被发现对心理生理性失眠的诊断至关重要。与良好的睡眠者相比，该分析有助于更好地理解心理生理性失眠症的定量规范方法。

Sleep Micro-Macro-structures in Psychophysiological Insomnia. PSG Study.

Study objectives: To address sleep micro-macro-structures in psychophysiological insomnia (PPI) as denoted by cyclic alternating pattern (CAP), Sleep spindles, and hyperarousal as microstructures and sleep characteristics such as sleep stages' variables, and heart rate as macrostructures.

Methods: Two statistical populations, with 20 participants in each, are addressed: good sleepers (GS) and patients with psychophysiological insomnia (PPI). The sleep polysomnography (PSG) for one night was performed and sleep macro-micro-structures extraction was implemented for each participant. Cyclic alternating patterns were scored manually and other structures were monitored by the original PSG's device software. Analytical methods are used to dissect the results.

Result: The findings imply: (a) psychophysiological insomnia is characterized by CAP differences from good sleepers which are associated with hyperarousal; (b) Regarding microstructure, more microarousals in sleep stages caused more number of wake index. (c) The ratio of sleep stages, sleep latency and heart rate as sleep macrostructure are significantly changed. (d) There is no significant difference between PPI and GS groups on spindles length in our research.

Conclusion: Regarding all sleep disorders and especially PPI, CAP variables, EEG arousals, and sleep spindles as microstructures and Total Sleep Time, Sleep Latency, number of waking, REM duration, and Heart Rate as macrostructures were found to be critical for the diagnosis of psychophysiological insomnia The analysis contributes to understanding better approaches in the quantitative specification of psychophysiological insomnia compare to good sleepers.

期刊介绍： Sleep, a pervasive, prominent and universal behavior, which occupies a third of human life. However, why we sleep remains unclear and it is one of the enigmas of modern neuroscience. Sleep loss and sleep deprivation has deleterious consequences. Many research laboratories across the globe evaluate sleep at the intersection between the cellular and the systems level. Such approaches are needed to understand the purpose of sleep. Within the sleep field, several of the predictions and hypotheses are often explored using simple to complex animal models, high-density EEG, and other synthetic approaches such as a large-scale computational simulation of multiple brain regions. Understanding how brain activity across behavioral states provide a conscious experience, which has pivotal implications for several clinical fields such as translational neuroscience, neuropsychiatry and neuropsychology. This is a rapidly growing area with a wide research base, yet currently has no dedicated journal. To fill the void, this is where the proposed journal ''Vigilance'' comes into picture. Vigilance will provide such unique platform to collect and disseminate state-of-the art scientific understanding on research in the increasingly overlapping fields of basic, translational and clinical sleep medicine. Vigilance will be a a Springer owned journal in collaboration and editorial support from the Indian Society for Sleep Research (ISSR), which aims to publish exemplary peer-reviewed manuscripts directing neurobiological investigation related to normal and altered vigilance states. Vigilance will be a broad-spectrum international scholarly journal, which aims to publish rigorously peer-reviewed, high quality research manuscripts within the biomedical as well as clinical research under one roof so that the translational research in sleep medicine can be nurtured and promoted. Therefore the wide scope of the journal will aid in contributing a great measure for the excellence in the scientific r esearch. Support in the research community for Vigilance has been widespread, and the journal has already secured several leaders in the field as members of its editorial board. This multidisciplinary journal will render a global podium for biomedical and clinical researchers to share their scientific excellence. Vigilance aims to attract research articles, case reports, clinical investigations, review articles and short communications from basic, translational, and clinical aspects of sleep research. Vigilance will cover a wide range of topics in this discipline and creates a platform for the authors to contribute towards the advancement in basic, translational, and clinical medicine. Areas covered include, but not limited to measurement of sleep across phylogeny, ontogeny, sleep functions, sleep organization at molecular, cellular, systems, and behavior levels, mechanisms of behavioral states regulation, molecular/genetic approach to studying sleep, neural substrates of altered states of consciousness, large-scale computer simulations to 3D modeling. At the clinical frontiers, areas such as chronobiology, primary sleep disorders and co-morbid sleep disorders will be covered. Journal will also cover translational and interdisciplinary clinical research related to all areas of sleep medicine in terms of diagnosis, treatment, and management of sleep disorders.
