The regulatory mechanism of physiological sleep-wake / 中国药理学通报

This paper explains the mechanism of the mutual switching between physiological sleep and wakefulness from the aspects of the sleep circadian system and the sleep homeostasis system. In the circadian rhythm system, with the suprachiasmatic nucleus as the core, the anatomical connections between the suprachiasmatic nucleusand various systems that affect sleep are summarized, starting from the suprachiasmatic nucleus, passing through the four pathways of the melatonin system, namely, subventricular area of the hypothalamus, the ventrolateral nucleus of the preoptic area, orexin neurons, and melatonin, then the related mechanisms of their regulation of sleep and wakefulness are expounded. In the sleep homeostasis system, with adenosine and prostaglandin D2 as targets, the role of hypnogen in sleep arousal mechanisms in regulation is also expounded.

Effect of mindfulness music training on sleep-wakefulness behavior in patients with acute stress disorder sleep disorder with cerebral hemorrhage / 中国神经精神疾病杂志

Objective To explore the effect of mindfulness-based music therapy (MBMT) on sleep-wakefulness behavior in patients with acute stress disorder (ASD) coexisting sleep disorder with cerebral hemorrhage. Methods A total of 70 patients with cerebral hemorrhage and ASD coexisting sleep disorders were randomly divided into two groups (n=35 each group). The study group was treated with mindfulness and soothing music training on the basis of routine treatment for 28 consecutive days. The control group only received routine treatment. Polysomnography (PSG) was used to compare sleep-wake behavior before and after intervention. Results After the intervention, the numbers of awakenings, awakenings greater than 5 min, micro awakenings, NREM micro awakenings, micro awakenings in phase 1, micro awakenings in phase 2, and REM awakenings were decreased in both groups (P<0.05). The degree of reduction of those parameters were greater and the proportion of total sleep time to recording time was longer in the study group than in the control group (P<0.05). Conclusion Music therapy based on mindfulness can effectively improve the sleep-wakeful behavior of ASD patients with cerebral hemorrhage, change the sleep process, and improve their sleep quality.
