Abstract
SCOPE Peanut stem and leaf (PSL), a traditional Chinese medicine, is widely used as a dietary supplement to improve sleep quality; however, the underlying mechanism is unclear. Here, the study aims to determine whether active compounds in PSL extract exert their effects by mediating neuronal excitability. METHODS AND RESULTS Aqueous PSL extract (500 mg kg-1 BW) increases the duration of total sleep (TS), slow wave sleep (SWS) and rapid eye movement sleep (REMS) in BALB/c mice after 7 and 14 continuous days of intragastric administration. Two PSL extract components with flavonoid-like structures: 4',7-di-O-methylnaringenin (DMN, 61 µg kg-1 BW) and 2'-O-methylisoliquiritigenin (MIL, 12 µg kg-1 BW), show similar effects on sleep in BALB/c mice. Moreover, incubation with DMN (50 µM) and MIL (50 µM) acutely reduces voltage-gated sodium and potassium currents and suppresses the firing of evoked action potential in mouse cortical neurons, indicating the inhibition on neuronal excitability. Meanwhile, RNA-seq analysis predicts the potential regulation of voltage-gated channels, which is according with the molecular docking simulation that both MIL and DMN can bind to voltage gated sodium channels 1.2 (Nav 1.2). CONCLUSIONS DMN and MIL are the active ingredients of PSL that improve sleep quality, suggesting that PSL promotes sleep by regulating the excitability of neurons.

Abstract
STUDY OBJECTIVES The objective was to determine the prevalence and predictors of comorbid insomnia in patients presenting for sleep surgery evaluation. The insomnia severity index (ISI) was utilized to evaluate patients' insomnia severity. METHODS A retrospective chart review was performed in patients presenting to an otolaryngology sleep surgery clinic; patients also completed a sleep history questionnaire. Patients were divided between those with and without clinically significant insomnia defined as ISI ≥ 15. RESULTS A total of 119 patients were included in the study: 50 (42%) with an ISI ≥ 15 and 69 (58%) with an ISI < 15. Clinically significant insomnia was associated with respiratory disturbance index (P = .028) but not apnea-hypopnea index or SaO2 nadir (P > .05). Clinically significant insomnia was associated with frequency of wake ups (P = .008), time to fall back asleep (P = .049), history of continuous positive airway pressure device use (P = .012), Epworth Sleepiness Scale (P = .008), and Sino-nasal Outcome Test (SNOT-22) (P < .001). CONCLUSIONS Patients reporting to a sleep surgery clinic are at an elevated risk for comorbid insomnia. The relationship between increased respiratory event-related arousals and nonsleep SNOT-22 scores to related sleep-maintenance insomnia supports the connection between insomnia, nasal obstruction, and continuous positive airway pressure intolerance.

Abstract
As the most common sleep disorder, insomnia seriously affects people's everyday lives. Phytochemicals have been shown to have excellent sleep-promoting effects. Therefore, this study was designed to investigate whether Rg5 and Rk1 extracted from ginseng had sleep-promoting effects and to explore their potential mechanisms. The results showed that Rg5 and Rk1 could significantly lessen the locomotor activity of mice and promote the sleep quality index, including increasing the amount of sleep in a pentobarbital sodium experiment with a threshold dose. In parallel, Rg5 and Rk1 could significantly shorten the sleep latency of mice and prolong the sleep time of mice. Furthermore, Rg5 and Rk1 augmented the GABA/Glu ratio, up-regulating the expression of the GABAA receptor and the GABAB receptor, whereas the GABAA receptor antagonist picrotoxin could antagonize the sleep quality of Rg5/Rk1. In addition, 5-HTP, the precursor of 5-HT, could enhance the sleep effect of Rg5 and Rk1 in mice, and both Rg5 and Rk1 could up-regulate the expression of 5-HT1A. These results were also confirmed by the detection of GABA and 5-HT in mouse cecum content. In conclusion, ginsenoside Rg5/Rk1 can exert sedative and hypnotic effects by affecting the GABA nervous system and the serotonin nervous system.

Abstract
Ginsenosides, as major active components of ginseng, possess various pharmacological activities, including anti-tumor, anti-diabetic and hypotensive effects. However, the sedative and hypnotic effect of ginsenosides and the involved mechanism remain unclear. In the present study, the hypnotic effect of rare protopanaxadiol-type (PD) ginsenosides, consisting of Rg3, Rk1, Rg5, and protopanaxatriol-type (PT) ginsenosides, consisting of Rh1, Rk3, Rh4, was investigated and compared in rodent models through behavioral pharmacology methods. Both rare PD and PT ginsenosides decreased spontaneous locomotion activity in normal mice and reduced sleep latency, and extended sleep duration in pentobarbital-treated mice. Moreover, PD and PT ginsenosides attenuated the insomnia induced by caffeine in mice. These hypnotic effects of PD and PT ginsenosides were potentiated by 5-hydroxytryptophan (5-HTP), a precursor of serotonin, and inhibited by p-chlorophenylalanine (PCPA), a 5-HT synthesis inhibitor. Flumazenil (FLU, a specific gamma aminobutyric acid (GABA) antagonist) also impaired the hypnotic effect of both PD and PT ginsenosides. The aforementioned results indicated that PD and PT ginsenosides exhibit sedative and hypnotic activity, and PT ginsenosides show higher activity than PD ginsenosides at high doses (96 mg kg−1). Furthermore, the bioactivity of these two types of ginsenosides might be mediated via the serotonergic and GABAergic systems. Ginsenosides, as major active components of ginseng, possess various pharmacological activities, including anti-tumor, anti-diabetic and hypotensive effects.![]()

Abstract
The main pharmacological effects of sedative agents are sedation, hypnosis, antianxiety, and antidepression. Traditional Chinese medicine (TCM) has a long history of clinical experience in treating insomnia. This review focuses mainly on the role of active ingredients from TCM in the treatment of insomnia. Single herbs and their active ingredients from TCM with hypnotic effects are summarized through reviewing the relevant literature published in the past 20 y. The active ingredients are divided into alkaloids, terpenoids, and volatile oils, flavonoids, lignanoids and coumarins, saponins, and others. Current studies on TCM in treating insomnia are described from the aspects of active ingredients, sources, experimental models and methods, results, and mechanisms. In addition, Chinese compound prescriptions developed from a variety of single herbs with sedative-hypnotic effects are introduced. The acting pathways of TCM are covered from the perspectives of regulating central neurotransmitters, influencing sleep-related cytokines, and improving the structure of the central nervous system.

Abstract
ABSTRACT Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality and may frequently be complicated by sleep disorders. Insomnia and obstructive sleep apnea are commonly encountered in patients with COPD. Nocturnal hypoxemia is also prevalent in COPD may occur despite adequate awake oxygenation and can be especially severe in rapid eye movement sleep. Additionally, several factors--some of them unique to COPD--can contribute to sleep-related hypoventilation. Recognition of hypoventilation can be vital as supplemental oxygen therapy itself can acutely worsen hypoventilation and lead to disastrous consequences. Finally, accruing data establish an association between restless leg syndrome and COPD--an association that may be driven by hypoxemia and/or hypercapnia. Comorbid sleep disorders portend worse sleep quality, diminished quality of life, and multifarious other adverse consequences. The awareness and knowledge regarding sleep comorbidities in COPD has continued to evolve over past many years. There are still several lacunae, however, in our understanding of the etiologies, impact, and therapies of sleep disorders, specifically in patients with COPD. This review summarizes the latest concepts in prevalence, pathogenesis, diagnosis, and management of diverse sleep disorders in COPD.

Abstract
There is increasing awareness of the role of sleep disturbance as an important factor in health and disease. Although sub-clinical sleep disturbances (insufficient sleep duration or inadequate sleep quality) may be difficult to assess with conceptual and/or methodological clarity, this review attempts to summarize and synthesize these findings. First, the concept of sleep disturbance in a public health context is introduced, to provide context and rationale. Second, operational definitions of 'cardiometabolic disease' and 'sleep disturbance' are offered, to address many unclear operationalizations. Third, the extant literature is summarized regarding short or long sleep duration and/or insufficient sleep, insomnia and insomnia symptoms, general (non-specific sleep disturbances), circadian rhythm abnormalities that result in sleep disturbances, and, briefly, sleep-disordered breathing. Fourth, the review highlights the social/behavioural context of sleep, including discussions of sleep and race/ethnicity, socio-economic position, and other social/environmental factors, in order to place these findings in a social-environmental context relevant to public health. Fifth, the review highlights the issue of sleep as a domain of health behaviour and addresses issues regarding development of healthy sleep interventions. Finally, a research agenda of future directions is proposed.

Abstract
BACKGROUND Chinese herbal medicine is one of the most popular Chinese medicine (CM) therapies for primary insomnia. One of the important characteristics of CM is that different Chinese clinicians give different prescriptions even for the same patient. However, there must be some fixed drug patterns in every clinician's prescriptions. This study aims to screen the effective core drug patterns in primary insomnia treatment of three prestigious Chinese clinicians. METHODS/DESIGN A triple-blind, randomized, placebo-controlled, parallel-group clinical trial will be performed. Three clinicians will diagnose and treat every eligible patient individually and independently, producing three prescriptions from three clinicians for every patient. Patients will equally be randomized to one of four groups - medical group A, medical group B, medical group C, or placebo group - and observed for efficacy of treatment. The sample will include primary insomnia patients meeting DSM IV-TR criteria, Spiegel scale score >18, and age 18 to 65 years. A sequential design is employed. Interim analysis will be conducted when between 80 and 160 patients complete the study. The interim study could be stopped and treated as final if a statistically significant difference between treatment and placebo groups can be obtained and core effective drug patterns can be determined. Otherwise, the study continues until the maximum sample size reaches 300. Treatment of the CM group is one of three Chinese clinicians' prescriptions, who provide independently prescriptions based on their own CM theory and the patient's disease condition. Assessment will be by sleep diary and Pittsburgh sleep quality index, and CM symptoms and signs will be measured. Primary outcome is total sleep time. Assessment will be carried out at the washout period, weeks 1, 2, 3, and 4 and 4th week after the end of treatment. Effectiveness analysis will be per intent to treat. A multi-dimension association rule and scale-free networks method will be used to explore the effective core drug patterns. DISCUSSION The effective core drug patterns will be found through analyzing several prestigious CM clinicians' treatment information. Screening the effective core drug patterns from prestigious clinicians can accelerate the development of new CM drugs. TRIAL REGISTRATION NCT01613183.

Abstract
Two sets of contributory factors to depression among patients with rheumatoid arthritis (RA) are generally examined - the social context of the individual and the biologic disease state of that person's RA. This article will review the evidence for both. RA affects patients both physically and psychologically. Comorbid depression is common with RA and leads to worse health outcomes. Low socioeconomic status, gender, age, race/ethnicity, functional limitation, pain and poor clinical status have all been linked to depression among persons with RA. Systemic inflammation may also be associated with, cause, or contribute to depression in RA. Understanding the socioeconomic factors, individual patient characteristics and biologic causes of depression in RA can lead to a more comprehensive paradigm for targeting interventions to eliminate depression in RA.
