    Abstract Hypobaric hypoxia in regions of high altitude may increase the risk of having sleep-disordered breathing (SDB). SDB at high altitude mainly refers to the SDB incurred in highlanders and lowlanders at a high altitude. At present, research on SDB at high altitude is mainly focused on these two groups of people. On the one hand, highlanders have SDB at a higher prevalence and greater severity than lowlanders do and highlanders have a prolonged duration of apnea when they travel to low-altitude regions. On the other hand, the severity of SDB increased in lowlanders when they travel to high altitude, represented mainly by an increase in central and hypopnea events. In terms of treatment, a substantial number of studies have shown that medication, including acetazolamide and dexamethasone, and nocturnal oxygen supplementation could improve SDB in lowlanders when they travel to high altitude. However, not much research has been done on the treatment of SDB in highlanders and it has only been reported that nocturnal oxygen supplementation was an available treatment option. Herein, we summarized the latest research findings on SDB at high altitude, providing the basis for further studies about the characteristics and treatments for highlanders with SDB.

    Abstract Obstructive sleep apnea (OSA) and depressive disorders are common diseases in adults and they share in common many clinical symptoms, including sleep disturbance, fatigue, lack of concentration and cognitive function impairment. OSA and depressive disorders also share some common pathophysiological changes, including increased activity of the hypothalamic-pituitary-adrenal (HPA) axis, chronic low-grade inflammation, oxidative stress, and changes in gut microbiota and neurotransmitters, which may contribute to the comorbidity of OSA and depressive disorders. In the case of comorbid OSA and depressive disorders, OSA and depressive disorders may affect and exacerbate each other, thereby increasing the severity of diseases, entailing greater risk of cardiovascular and metabolic diseases, and causing greater difficulty in treatment. Herein, we summarized the latest research findings on the epidemiology, possible mechanisms, harms, and treatment of comorbid OSA and depressive disorders. This review may help improve clinicians' understanding of the comorbidity of OSA and depression disorders, thereby promoting early screening, prompt diagnosis and treatment, and improved prognosis. Further studies are needed for better understanding of the effect of the comorbidity of OSA and depressive disorders and treatment on cardiometabolic diseases.

    Abstract Humans spend one third of their life sleeping. Sleep, a vital life process, is an essential part of human health. In response to people's growing needs concerning sleep health, sleep medicine was born and is growing rapidly, and there is also an upsurge in the construction of sleep medicine centers in China and other countries. Unfortunately, there are no Chinese standards available for the construction of sleep medicine centers and the sleep medicine centers already constructed are of varied quality. In view of this academic problem, Professor Lu Lin, an academician of Chinese Academy of Sciences and the president of Peking University Sixth Hospital, organized Chinese experts with outstanding achievements in the field of sleep medicine to draft "Guideline for the Standardized Construction of Sleep Medicine Centers in China". This guideline mainly introduces the overall status of standardized construction of sleep medicine centers and the status of the construction of specialized sleep medicine centers in China, aiming to guide the construction of high-quality and high-standard sleep medicine centers in China, to promote the development of sleep medicine, and to safeguard people's sleep health.

    Abstract Post-traumatic stress disorder (PTSD) is characterized by intrusive emotional memory, alertness and avoidance after individuals suffer from one or more traumatic events. With the exception of manifestations, sleep disturbances are also considered to be the core symptoms of PTSD. This article mainly discussed insomnia, nightmares, obstructive sleep apnea (OSA), and periodic limb movement during sleep (PLMS) in patients with PTSD. Existing evidence suggested that insomnia is a predictor of the development of PTSD. Cognitive behavioral therapy for insomnia is an important research direction for treating insomnia in PTSD patients. Nightmares are also the core symptom of PTSD. Prazosin and image rehearsal therapy are effective therapies to treat post-traumatic nightmares. The co-occurrence of obstructive sleep apnea (OSA) is over 40% in patients with PTSD. Preliminary studies have shown that continuous positive airway pressure therapy can improve PTSD symptoms in patients with PTSD comorbid OSA. In the process of diagnosis and treatment of PTSD patients, it is important to firstly evaluate whether PTSD patient comorbid OSA or insomnia, and then clinicians could further develop an appropriate treatment plan for these patients.

    Abstract Objective: To explore the characteristics of patients with obstructive sleep apnea (OSA) and comorbid primary aldosteronism (PA) and to explore the relevant factors affecting plasma aldosterone concentration.
    Methods: A total of 105 patients diagnosed with PA and admitted at West China Hospital, Sichuan University between January 2016 and December 2021 were retrospectively analyzed. The subjects were divided into a PA with comorbid snoring group (
    Results: Compared with patients with only OSA, a significantly higher proportion of patients with OSA and comorbid PA had hypertension and elevated levels of systolic and diastolic blood pressure (
    Conclusion: Comorbidity with PA can aggravate the clinical manifestations of OSA, while OSA further disrupted the metabolism of lipids and uric acid in PA patients. Plasma aldosterone concentrations in patients with comorbid OSA and PA were affected by the lowest oxygen saturation level.

    Abstract The quality of sleep, a key physiological factor that regulates information, memory, decision making, and other vital brain functions, can affect important physiological functions of the human body. According to disease classification systems, sleep disorders can be categorized into more than 90 types, including sleep apnea, insomnia, and hypersomnia. It may cause a variety of adverse consequences, such as depression, anxiety and other emotional disorders, as well as physical diseases such as hypertension, diabetes and stroke. In addition, the relevant cardiovascular and cerebrovascular diseases and cognitive impairment not only harm physical health, but also are associated with workplace accidents and safety problems, constituting public safety hazards. Sleep disorders have become a major social and scientific problem that impacts on the national economy and the livelihood of the people. Research on sleep disorders should be given more attention by researchers and policy makers. Herein, we mainly discussed the latest findings and difficulties concerning research on the prevention and intervention of sleep disorders and proposed strategies and suggestions accordingly.

    Abstract Objective: Excessive daytime sleepiness (EDS) is associated with cardiovascular events in patients with obstructive sleep apnea (OSA). Our study explored the correlation between objective daytime sleepiness assessed with daytime multiple sleep latency tests (MSLT) and heart rate variability (HRV) in OSA patients. The results may provide insight into possible mechanisms underlying increased risk of cardiovascular events in patients with OSA.
    Methods: A retrospective analysis was conducted with the data of 139 patients with OSA and 35 patients with primary snoring. All subjects underwent polysomnography (PSG) and MSLT at West China Hospital between January 2019 and May 2022. We used mean sleep latency (MSL) to measure the severity of EDS and to categorize OSA patients into three groups, severe EDS, light EDS, and non-EDS, with MSL of less than 5 minutes, 5 to 10 minutes, and greater than 10 minutes as the respective defining criteria for classification. A comparison of sleep structure, clinical characteristics, and HRV parameters was performed in order to evaluate the difference between OSA subgroups with varying levels of objective EDS and the primary snoring group. In addition, we also analyzed the correlation between MSL and HRV parameters.
    Results: Severe EDS patients had higher values of standard deviation of all N-N intervals (SDNN), total spectral power (TOT), and low-frequency power (LF) as compared to non-EDS patients, which was indicative of sympathetic stimulation (
    Conclusion: OSA patients with objective EDS have elevated sympathetic drive and decreased parasympathetic drive. A positive correlation was found between this change in neural activity and the shortening of MSL.

    Abstract Objective: To study the sleep electroencephalogram (EEG) power features of patients with chronic insomnia.
    Methods: Retrospective analysis was performed with patients who met the ICD-10 diagnostic criteria for chronic insomnia, using polysomnography (PSG) to examine the overnight sleep EEG. The sleep architectures and relative EEG power across five frequency bands during overnight sleep were compared to study the differences between the insomnia and control groups. Furthermore, the correlation between EEG power and various PSG measures was also analyzed.
    Results: Forty-five subjects were enrolled in the study, including 25 chronic insomniacs (18 females, aged [36.2±10.7] years) and 20 controls (18 females, aged [36.1±7.6] years). Compared to those of the control group, insomnia patients had significantly lower value of delta power ([38.0±6.1] vs. [43.2±5.8],
    Conclusion: The results suggest that patients with chronic insomnia have decreased low-frequency EEG power, but increased high-frequency EEG power during NREM sleep. The findings indicate that cortex arousal level is elevated in chronic insomniacs during NREM sleep.

    Abstract Insomnia is one of the most common and burdensome disorders in adults. We compared and ranked insomnia medication on the basis of their efficacy and tolerability. We performed a systematic review and network meta-analysis of placebo-controlled or head-to-head randomized controlled trials for primary insomnia in adults comparing 20 drugs. We searched eight databases and seven trial registers from inception to March 1st, 2022. Primary outcomes included sleep latency (SL), awake time after sleep onset (WASO) and discontinuation for adverse events (AED), and secondary outcomes included total sleep time (TST), sleep efficiency (SE), sleep quality (SQ) and adverse events (ADE). Pooled standardized mean differences or odds ratios with 95% credible intervals were estimated using pairwise and network meta-analysis with random-effects. Differences among trial findings were explored in subgroup and sensitivity analyses. Confidence in evidence was assessed using GRADE. The PROSPERO registered number is CRD42020182144. We identified 22,538 records and included 69 studies (17,319 patients). Orexin receptor antagonists (ORAs) are more efficacious than benzodiazepine-like drugs (Z-drugs) and placebo for WASO and SE, and better than melatonin receptor agonists (MRAs) for SL, WASO and SE. ORAs ranked the best in SL (SUCRA value: 0.84), WASO (0.93), TST (0.86) and SE (0.96). Lemborexant and daridorexant (two ORAs) showed greater efficacy than placebo for SL, WASO, and TST, with good tolerability. Z-drugs were more efficacious than placebo for SL, WASO, TST and SE, but with higher risk to safety. Zaleplon and eszopiclone had better efficacy than placebo for TST and SQ respectively. MRAs may also be efficacious for sleep-onset insomnia with good safety. However, the long-term adverse effects of all medications are unclear. Insomnia medications differ in their efficacy and tolerability. ORAs have superior efficacy and tolerability. These findings should aid clinicians in matching risk/benefits of drugs available in their countries to insomnia symptoms.
