Objective Narcolepsy type 1 （NT1） is known to be associated with low levels of hypocretin-1 （Hcrt-1） in cerebrospinal fluid （CSF）. The standard method for Hcrt-1 measurement is radioimmunoassay （RIA） with imported reagents， but this antibody-dependent method is limited to radiation safety-certified lab， gradual radioactivity degradation， and slow turn-around time. The purpose of this study is to explore a non-radioactive， faster， and antibody independent domestic method in China for Hcrt-1 detection. Methods Repeated testing of cerebrospinal fluid from 14 clinically diagnosed NT1 patients and 10 non-narcolepsy patients was performed using liquid chromatography-tandem mass spectrometry （LC-MS/MS）technology，including the establishment and optimization of fundamental methodological procedures. The main steps involved the addition of non-radioactive isotope-labeled internal standards to the cerebrospinal fluid， followed by solid-phase extraction， mass spectrometry signal acquisition， and quantitative analysis. The results were then compared with the corresponding radioimmunoassay（RIA） findings. Results The LC-MS/MS method showed faster speed， and good linearity across a wider range of synthesized standard（5~2 500 pg/ml）， and good repeatability. Although this absolute-quantitation-based LC-MS/MS method and RIA method have different reading values in Hcrt-1 quantitation， they both can segregate NT1 group from non-NT1 group well. Conclusion Although larger cohorts are needed to set up a standard method in China，LC-MS/MS method is proved to be an easier， safer， faster， and possibly more accurate method for Hcrt-1 quantitation and detection for NT1 diagnosis.

Narcolepsy（NP） is a rare central sleep disorder， and it is categorized into narcolepsy type1 （NT1） and narcolepsy type2（NT2）.The main clinical symptoms of NP include daytime lethargy， cataplexy induced by emotions， and sleep paralysis， with a peak onset during adolescence （with an age of 8‒12 years）. At present， the pathogenesis of NP remains unclear and is associated with various factors such as human leucocyte antigen （HLA）， infection， and epigenetic silencing， and the selective loss of hypocretin neurons in the hypothalamus is the key pathophysiological mechanism of NP. Pharmacological intervention is currently the main treatment method， and diagnostic delay can be as long as more than 10 years， which not only affects the social activities， academic performance， and work of patients， but also leads to mental health issues such as anxiety and depression. This article reviews the latest research findings in the epidemiology， pathogenesis， and treatment of NT1 and clarifies the deficiencies and controversies in current research， so as to provide new ideas and directions for subsequent studies.

Objective The efficacy and safety of pitolisant in the treatment of adult narcolepsy have been confirmed in clinical trials abroad， but there is a lack of data on the application of pitolisant in Chinese patients. The aim of this study is to investigate the efficacy and safety of pitolisant in the treatment of adult narcolepsy in China.Methods A total of 30 subjects were enrolled in this study and were given individualized titration once a day for 8 weeks. Epworth Somnolence Scale （EES） and daily cataplexy rate （DCR） were used as the primary outcome measures，and Clinical Global Impression-Severity scale（CGI-S） and Clinical Global Impression of Change Scale （CGI-C） were used as the secondary outcome measures；safety indicators included adverse event （AE） records and laboratory examination.Results The results showed that there were significant improvements in ESS score and number of cataplexy attacks after medication. At the end of treatment，ESS score was reduced by（7.63±4.79）（P<0.001）. For all subjects， the average daily number of cataplexy attacks was 0.83 at baseline，which was reduced significantly to （0.39±0.82）after 3 weeks of pitolisant treatment and（0.38±0.79）after 5 weeks of pitolisant treatment（P<0.05）. After the treatment ended， the median CGI-S score of excessive daytime sleepiness （EDS） improved from "severe" at baseline to "mild"（P<0.001）， and the CGI-S score of cataplexy improved from "mild" at baseline to "basically normal"（P<0.001）. Most AEs were mild and did not receive any drug treatment， and there were no significant changes in other laboratory markers used to monitor the general condition of the subjects before and after treatment. Conclusion Pitolisant has good efficacy and safety in the treatment of EDS and cataplexy in Chinese adults with narcolepsy.

OBJECTIVE: To observe the effect of Shugan Tiaoshen acupuncture (acupuncture for soothing the liver and regulating the mentality) combined with western medication on depression and sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, and investigate the potential mechanism from the perspective of cortical excitability. METHODS: Sixty patients with depression-insomnia comorbidity due to COVID-19 quarantine were randomly divided into an acupuncture group and a sham-acupuncture group, 30 cases in each one. The patients of both groups were treated with oral administration of sertraline hydrochloride tablets. In the acupuncture group, Shugan Tiaoshen acupuncture was supplemented. Body acupuncture was applied to Yintang (GV 24⁺), Baihui (GV 20), Hegu (LI 4), Zhaohai (KI 6), Qihai (CV 6), etc. The intradermal needling was used at Xin (CO₁₅), Gan (CO₁₂) and Shen (CO₁₀). In the sham-acupuncture group, the sham-acupuncture was given at the same points as the acupuncture group. The compensatory treatment was provided at the end of follow-up for the patients in the sham-acupuncture group. In both groups, the treatment was given once every two days, 3 times a week, for consecutive 8 weeks. The self-rating depression scale (SDS) and insomnia severity index (ISI) scores were compared between the two groups before and after treatment and 1 month after the end of treatment (follow-up) separately. The cortical excitability indexes (resting motor threshold [rMT], motor evoked potential amplitude [MEP-A], cortical resting period [CSP]) and the level of serum 5-hydroxytryptamine (5-HT) were measured before and after treatment in the two groups. RESULTS: After treatment and in follow-up, SDS and ISI scores were decreased in both groups compared with those before treatment (P<0.05), and the scores in the acupuncture group were lower than those in the sham-acupuncture group (P<0.05), and the decrease range in the acupuncture group after treatment was larger than that in the sham-acupuncture group (P<0.05). After treatment, rMT was reduced (P<0.05), while MEP-A and CSP were increased (P<0.05) in the acupuncture group compared with that before treatment. The levels of serum 5-HT in both groups were increased compared with those before treatment (P<0.05). The rMT in the acupuncture group was lower than that in the sham-acupuncture group, while MEP-A and CSP, as well as the level of serum 5-HT were higher in the acupuncture group in comparison with the sham-acupuncture group (P<0.05). CONCLUSION Shugan Tiaoshen acupuncture combined with western medication can relieve depression and improve sleep quality in the patients with depression-insomnia comorbidity due to COVID-19 quarantine, which is probably related to rectifying the imbalanced excitatory and inhibitory neuronal functions.

OBJECTIVE: To observe the clinical efficacy and safety of Jianpi Peiyuan acupoint thread embedding therapy on perimenopausal obesity (PMO). METHODS: Ninety-six patients of PMO were randomly divided into an observation group (48 cases) and a control group (48 cases). The control group received health education and lifestyle intervention. On the basis of the treatment in the control group, the observation group was treated with acupoint thread embedding at the main acupoints of Shangwan (CV 13), Zhongwan (CV 12), Xiawan (CV 10), Yinlingquan (SP 9) and Fenglong (ST 40), etc. as well as the supplementary acupoints in accordance with the syndrome differentiation, once every 2 weeks for 8 weeks (4 times in total). The indexes of obesity (body mass index [BMI], waist circumference, hip circumference and body mass), modified Kupperman score, insomnia severity index (ISI) score, self-rating anxiety scale (SAS) score, and self-rating depression scale (SDS) score of the two groups were observed before and after treatment, and the safety was evaluated. RESULTS: After treatment, BMI, waist circumference, hip circumference and body mass in the two groups were lower than before treatment (P<0.05), and those in the observation group were lower than the control group (P<0.05). After treatment, Kupperman, ISI and SAS scores in the observation group were lower than before treatment (P<0.05), and ISI score in the control group was lower than before treatment (P<0.05). Kupperman, ISI and SAS scores in the observation group were lower than those in the control group (P<0.05). There was no significant difference in SDS between the two groups or within groups (P>0.05). No serious adverse reactions occurred during the experiment. CONCLUSION Jianpi Peiyuan acupoint thread embedding therapy can reduce the degree of obesity in PMO patients, and improve patients' the perimenopausal symptoms, insomnia and anxiety, with good safety.

OBJECTIVES: Shelter hospital was an alternative way to provide large-scale medical isolation and treatment for people with mild coronavirus disease 2019 (COVID-19). Due to various reasons, patients admitted to the large shelter hospital was reported high level of psychological distress, so did the healthcare workers. This study aims to introduce a comprehensive and multifaceted psychosocial crisis intervention model. METHODS: The psychosocial crisis intervention model was provided to 200 patients and 240 healthcare workers in Wuhan Wuchang shelter hospital. Patient volunteers and organized peer support, client-centered culturally sensitive supportive care, timely delivery of scientific information about COVID-19 and its complications, mental health knowledge acquisition of non-psychiatric healthcare workers, group activities, counseling and education, virtualization of psychological intervention, consultation and liaison were exhibited respectively in the model. Pre-service survey was done in 38 patients and 49 healthcare workers using the Generalized Anxiety Disorder 7-item (GAD-7) scale, the Patient Health Questionnaire 2-item (PHQ-2) scale, and the Primary Care PTSD screen for the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (PC-PTSD-5). Forty-eight healthcare workers gave feedback after the intervention. RESULTS: The psychosocial crisis intervention model was successfully implemented by 10 mental health professionals and was well-accepted by both patients and healthcare workers in the shelter hospital. In pre-service survey, 15.8% of 38 patients were with anxiety, 55.3% were with stress, and 15.8% were with depression; 16.3% of 49 healthcare workers were with anxiety, 26.5% were with stress, and 22.4% were with depression. In post-service survey, 62.5% of 48 healthcare workers thought it was very practical, 37.5% thought more practical; 37.5% of them thought it was very helpful to relief anxiety and insomnia, and 27.1% thought much helpful; 37.5% of them thought it was very helpful to recognize patients with anxiety and insomnia, and 29.2% thought much helpful; 35.4% of them thought it was very helpful to deal with patients' anxiety and insomnia, and 37.5% thought much helpful. CONCLUSIONS Psychological crisis intervention is feasible, acceptable, and associated with positive outcomes. Future tastings of this model in larger population and different settings are warranted.

OBJECTIVES: The use of anticholinergic drugs in the elderly may lead to negative events such as falls, delirium, urinary retention and cognitive decline, and the higher the number of anticholinergic drugs use, the more such negative events occur. This study aims to analyze the risk factors associated with the prescription of total anticholinergic drugs in elderly outpatients and evaluate the rationality of anticholinergic drugs, and to provide a reference for reducing the adverse effects of anticholinergic drugs. METHODS: A list of drugs with anticholinergic activity based on the Beers criteria was established. The basic information (such as age and gender), clinical diagnosis, and medications of elderly outpatient were extracted from hospital electronic medical records, and the Anticholinergic Cognitive Burden (ACB) Scale was used to calculate the anticholinergic burden for each patient. Logistic regression analysis was used to identify the potential risk factors for the occurrence of problems such as multiple medication and insomnia. RESULTS: A total of 1 840 prescriptions for elderly patients were reviewed. Of these patients, ACB score was more than or equal to 1 in 648 (35.22%) patients. Number of prescription medication (95% CI: 1.221 to 1.336) and insomnia (95% CI: 3.538 to 6.089) were independent factors affecting ACB scores (both P<0.01). Medications for patients of ACB scores were most commonly treated with the central nervous system drugs (such as alprazolam and eszopiclone) and for the cardiovascular system drugs (such as metoprolol and nifedipine). CONCLUSIONS There is a high rate of ACB drugs use in geriatric patients, and the clinical focus should be on multiple medication prescriptions, especially on the central nervous system drugs (such as alprazolam and eszopiclone) and cardiovascular system drugs (such as metoprolol and nifedipine). The prescription review should be emphasized to reduce adverse reactions to anticholinergic drugs in elderly patients.

Objective: The aim of this study was to determine the comorbid sleep disorders on Polysomnography (PSG) of patients complaining of insomnia symptoms. Methodology: This is a retrospective study among patients who underwent diagnostic and split-night polysomnography from April 2014 to February 2019. Those who had at least one of the following insomnia symptoms of difficulty initiating sleep, difficulty maintaining sleep and early morning awakening with or without a history of sleep aide use were identified as patients with insomnia. Polysomnography sleep parameters and outcome were tabulated and statistical analysis was done using SPSS v 20.0. Results: Out of the 302 patients who were included in the study, 34.4% of subjects had a family history of sleep disorder and 70.4% had a history of sleep aide use. Among the medical comorbidities, 47.7% of the subjects were diagnosed with hypertension while 10.65% were diagnosed with psychiatric disorder. Most of the patients complained of both difficulty initiating sleep and early morning awakening. PSG sleep parameters showed that patients did not experience excessive daytime sleepiness or delayed sleep latency. On the other hand, poor sleep efficiency could be due to increased arousal index. Half of the patients turned out to have severe obstructive sleep apnea (52%) while 2.3% of the patients had periodic limb movement disorder. Among those diagnosed with severe OSA, 53.3% had a history of sleep aide use. Conclusion The study showed the importance of screening patients with insomnia for underlying comorbid sleep disorders. The American Academy of Sleep Medicine (AASM) treatment guidelines for chronic insomnia emphasized the need to have a high index of suspicion for this population in order to recommend diagnostic procedures such as polysomnography. Diagnosing a patient with insomnia to have an underlying sleep apnea and/or periodic limb movement disorder would change the course of management among patients with chronic insomnia and eventually avoid prescribing medications that could actually worsen the patient’s condition.

Insomnia induced by mental retardation is related to the synergistic dysfunction of "shaoyang, sanjiao and haishi (the period of the day from 9 pm to 11 pm) " in pathogenesis. Based on "trinity theory of shaoyang, sanjiao and haishi ", the acupoints of hand and food shaoyang meridians on the head and face (Fengchi [GB 20], Sizhukong [TE 23] and Jiaosun [TE 20]) and those on the four limbs (Sanyangluo [TE 8], Zhongzhu [TE 3], Qiuxu [GB 40] and Xiaxi [GB 43]) are selected to regulate the pivot function of shaoyang. Front-mu and back-shu points (Sanjiaoshu [BL 22], Danzhong [CV 17] and Tianshu [ST 5]), as well as auricular points (Gan [CO₁₂], Dan [CO₁₁] and Sanjiao [CO₁₇]) are chosen to promote qi circulation of shaoyang and sanjiao meridians. In association with the relevant knowledge of time acupuncture at haishi, the circadian rhythm of sleep is set up and the appropriate sleep pattern is developed.

OBJECTIVE: To observe the effects of Tiaoshen (regulating the spirit) acupuncture on cognitive function and sleep quality in patients with primary insomnia (PI). METHODS: Sixty patients with PI were randomly divided into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 2 cases dropped off, 1 case was excluded). The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Sishencong (EX-HN 1), and bilateral Benshen (GB 13), Shenmen (HT 7), Neiguan (PC 6), Sanyinjiao (SP 6). The patients in the control group were treated with shallow needling at non-effective points. Each treatment was provided for 30 min, once every other day, 3 treatments per week for 4 weeks. The Montreal cognitive assessment (MoCA), digit span test (DST), trail making test (TMT)-A, Pittsburgh sleep quality index (PSQI), and fatigue scale-14 (FS-14) were used to assess cognitive function and sleep quality before and after treatment, as well as in follow-up of 4-week after treatment completion. Correlation analysis was conducted between the differences in PSQI scores and differences in MoCA scores before and after treatment in the observation group. RESULTS: Compared with before treatment, the total score, visuospatial and executive function score and delayed memory score of MoCA as well as DST backward score were increased (P<0.01), while TMT-A time, PSQI and FS-14 scores were significantly reduced (P<0.01) after treatment and in follow-up in the observation group. Compared with before treatment, the PSQI score in the control group was reduced (P<0.01, P<0.05). After treatment and in follow-up, the observation group had significantly higher total score, visuospatial and executive function score, delayed memory score of MoCA, and DST backward score compared to the control group (P<0.05, P<0.01). In the observation group, the TMT-A time was significantly shorter than that in the control group (P<0.05, P<0.01), and the PSQI and FS-14 scores were significantly lower than those in the control group (P<0.01). In the observation group, there was a negative correlation between the difference in PSQI scores (post-treatment minus pre-treatment) and the difference in MoCA scores (post-treatment minus pre-treatment) (r=-0.481, P<0.01). A similar negative correlation was found between the difference in PSQI scores (follow-up minus pre-treatment) and the difference in MoCA scores (follow-up minus pre-treatment) (r=-0.282, P<0.05). CONCLUSION Tiaoshen acupuncture could improve cognitive function, enhance sleep quality, and alleviate daytime fatigue in patients with PI. The improvement in cognitive function in patients with PI is correlated with the improvement in sleep quality.
