ABSTRACT
Objective:To investigate the feasibility of blue velvet arena test (BVAT) in evaluating spatial memory function in patients with chronic insomnia disorder (CID).Methods:From June 1, 2021 to May 31, 2022, 62 CID outpatients or inpatients were enrolled continuously in the Department of Sleep Disorders, the Affiliated Chaohu Hospital of Anhui Medical University, and 56 good sleepers in the same period were enrolled to serve as controls. Pittsburgh Sleep Quality Index (PSQI) was used to assess their sleep quality. Montreal Cognitive Assessment Scale (MoCA), nine box maze test (NBMT), and BVAT were used to assess general cognition and memories.Results:Compared to the controls, the CID patients had increased PSQI score [15.0 (12.8, 16.0) vs 0 (0, 1.0); Z=-9.47, P<0.001], and decreased MoCA score [24.5 (21.5, 27.0) vs 27.0 (26.0, 28.0); Z=-4.18, P<0.001]; increased numbers of errors in the spatial working [1.0 (0.8, 2.0) vs 1.0 (0, 1.0); Z=-2.24, P<0.05], object working [1.5 (0.8, 3.0) vs 0 (0, 1.0); Z=-4.36, P<0.001] and object recognition [0 (0, 0) vs 0 (0, 0); Z=-2.10, P<0.05] memories in NBMT; and increased average erroring distance in BVAT [23.0 (16.4, 27.2) cm vs 18.7 (16.6, 20.7) cm; Z=-3.30, P<0.01]. Partial correlation analysis showed that in the CID patients, the average erroring distance in BVAT was positively correlated with erroneous numbers in spatial working memory in NBMT ( r=0.54, P<0.001). Principal components analysis showed that the average erroring distance of BVAT (load=0.844) and the errors of spatial working memory in NBMT (load=0.801) were jointly attributed to the first factor. Receiver operating characteristic curve analysis showed that the sensitivity of BVAT was higher than that of NBMT (0.575 vs 0.250, P<0.05) for spatial memory detection in total sample. Conclusion:The BVAT has a higher reliability in the functional assessment of spatial memory in CID patients.
ABSTRACT
OBJECTIVE@#To observe the effects of acupuncture at "umbilical four-acupoints" on chronic insomnia and its comorbid symptoms.@*METHODS@#A total of 120 patients with chronic insomnia were randomly divided into an observation group (60 cases, 8 cases dropped off) and a control group (60 cases, 5 cases dropped off). The patients in the observation group were treated with acupuncture at regular acupoints (Baihui [GV 20] and bilateral Shenmen [HT 7], Neiguan [PC 6], Anmian [Extra]) and "umbilical four-acupoints", while the patients in the control group were treated with acupuncture at regular acupoints. Acupuncture was given once a day, 6 times a week, for a total of 3 weeks in the two groups. The Pittsburgh sleep quality index (PSQI), insomnia severity index (ISI) scores were observed before treatment, after treatment and in follow-up of one month after treatment completion; the Beck anxiety inventory (BAI), Beck depression inventory (BDI), fatigue severity scale (FSS), and Epworth sleepiness scale (ESS) scores were observed before and after treatment; the sleep parameters of polysomnography (PSG), including sleep latency (SL), awake-up time (AT), sleep efficiency (SE) and total sleep time (TST), were observed before and after treatment using polysomnography monitor in the two groups.@*RESULTS@#Compared with those before treatment, the PSQI and ISI scores in both groups were reduced after treatment and in follow-up (P<0.05), and the PSQI and ISI scores in the observation group were lower than those in the control group after treatment and in follow-up (P<0.05). Compared with those before treatment, the BAI, BDI, FSS and ESS scores in both groups were reduced after treatment (P<0.05), and the BAI, BDI, FSS and ESS scores in the observation group were lower than those in the control group after treatment (P<0.05). Compared with those before treatment, the SL and AT in both groups were reduced after treatment (P<0.05), while SE and TST were increased after treatment (P<0.05); after treatment, the SL and AT in the observation group were lower than those in the control group (P<0.05), while SE and TST in the observation group were higher than those in the control group (P<0.05).@*CONCLUSION@#On the basis of regular acupoint selection, acupuncture at "umbilical four-acupoints" could improve sleep quality, alleviate the severity of insomnia, and improve the comorbid symptoms i.e. anxiety, depression, fatigue and lethargy in patients with chronic insomnia.

ObjectiveTo explore the effect of Anmeidan on the sleep quality and serum levels of brain-derived neurotrophic factor （BDNF）， glial fibrillary acidic protein （GFAP）， and irisin in the patients with chronic insomnia. MethodA multicenter， randomized， double-blind， placebo-controlled clinical study was carried out， including 480 patients with chronic insomnia （deficiency syndrome） in Wuhan （Hubei）， Guangzhou （Guangdong）， and Lanzhou （Gansu）. They were randomized into an observation group and a control group at a ratio of 1∶1. The observation group was orally administered with Anmeidan granules at a dose of 11 g， 3 times per day， and the control group with Anmeidan simulant at a dose of 11 g， 3 times per day， Both groups of patients received sleep education after enrollment. After 4 weeks of medication， the Athens insomnia scale （AIS） scores， Spiegel scale scores， and serum levels of BDNF， GFAP， and irisin were compared between the two groups as well as between before and after treatment. ResultA total of 480 adult patients with chronic insomnia were enrolled in this study， with 64 patients falled off. Finally， the 415 patients were included in the analysis， including 213 patients in the observation group and 202 patients in the control group. There was no difference in age or sex between the two groups of patients. Compared with before treatment， the treatment in both groups decreased the AIS and Spiegel scores （P<0.01）. After treatment， the observation group had lower AIS and Spiegel scores than the control group （P<0.01）. The treatment in the observation group slightly lowered the level of BDNF， elevated the level of irisin （P<0.05）， and lowered the level of GFAP （P<0.05） in the serum. After treatment， the observation group showed higher level of irisin （P<0.05） and lower levels of BDNF and GFAP in the serum than the control group. ConclusionAnmeidan may improve the sleep quality of patients with chronic insomnia by elevating the irisin level and lowering the GFAP level in the serum.
ABSTRACT
Chronic insomnia is a common sleep disorder in clinic. It is a frequent and persistent difficulty in sleep initiation, maintenance and termination, leading to different degrees of functional impairment during daytime awakening. Although its pathogenesis is still not completely clear, some people have proposed neurobiological and psychological models, and more and more people begin to pay attention to the study of immune factors and genetic factors. The immune system mainly includes immune organs, immune cells and immune molecules, which help organisms maintain their homeostasis and normal life activities. There are intricate relations between sleep and immune system. Chronic insomnia can affect the function of immune system, and immune disorder may in turn lead to chronic insomnia. This paper discusses the changes of immune system in patients with chronic insomnia, and the influence of immune system changes on patients with chronic insomnia, as well as the research progress of the correlation between chronic insomnia and immune function.
ABSTRACT
Objective:To explore the clinical significance of event-related potential P300 in the diagnosis and treatment of cognitive function in patients with chronic insomnia combined with anxiety and depression.Methods:Sixty patients with chronic insomnia complicated with anxiety and depression treated in Wuhan First Hospital from October 2020 to March 2021 were selected as the observation group, and 60 healthy volunteers were selected as the control group in the same period.Hamilton anxiety scale (HAMA) and Hamilton depression scale (HAMD) were used to evaluate the anxiety and depression status of patients.Mini mental state examination (MMSE) and Montreal cognitive assessment scale (MoCA) were used to evaluate the cognitive function of the subjects.All subjects were tested for P300 event-related potential, and the latency and amplitude of P300 event-related potential were recorded.SPSS 25.0 software was used for statistical analysis.Independent sample t-test was used for comparison between groups.Pearson correlation analysis was used to analyze the correlation between cognitive function and P300 event-related potential. Results:The scores of HAMA ((16.65±5.10), (9.30±4.42)) and HAMD ((18.07±3.97), (8.48±3.21)) in the observation group were higher than those in the control group ( t=8.438, 14.545, both P<0.05), and the MoCA score (22.35±4.25) was lower than that(25.65±2.29) in the control group ( t=-5.291, P<0.05). In the eight dimensions of MoCA, the scores of visual space and executive ability ((3.38±1.46), (4.63±0.69)), naming ((2.37±0.78), (2.65±0.48)), language ((2.17±0.96), (2.53±0.81)) and delayed recall ((2.58±1.45), (4.17±0.85))in the observation group were lower than those in the control group ( t=-5.991, -2.394, -2.259, -7.292, all P<0.05). Compared with the control group, the latencies of P300 (N1, N2, P3) in the observation group were significantly prolonged ( t=3.281, 4.342, 4.492, all P<0.01). The latencies of P300 (N1, N2, P3) were positively correlated with HAMD score ( r=0.242, 0.301, 0.311, all P<0.05). The latencies of P300 (N2, P3) were positively correlated with HAMA score ( r=0.205, 0.207, both P<0.05). The latencies of P300 (N2, P3) were negatively correlated with the delayed recall score of MoCA ( r=-0.197, -0.236, both P<0.05). Conclusion:There are different degrees of cognitive impairment in patients with chronic insomnia combined with anxiety and depression.P300 in patients with chronic insomnia combined with anxiety and depression shows prolonged latency.P300 latency is related to depression, anxiety and cognition in patients with chronic insomnia combined with anxiety and depression.Event-related potential P300 may be used as a neurophysiological objective evaluation tool for cognitive impairment in patients with chronic insomnia combined with anxiety and depression.
ABSTRACT
Objective:To observe the clinical efficacy of repetitive transcranial magnetic stimulation (rTMS) combined with eszopiclone in the treatment of chronic insomnia disorder and its influence on brain electrical activity.Methods:Ninety patients with chronic insomnia were randomly divided into rTMS group, drug group and combination group, with 30 cases each group. The rTMS group was treated with bilateral dorsolateral prefrontal lobe (left 5 Hz 400 pulse, right 1 Hz 1 200 pulse), the drug group was treated with eszopiclone (3mg/d) and the combination group was treated with rTMS + eszopiclone. Continuous treatment for 2 weeks, Pittsburgh sleep quality index (PSQI), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and changes in brain electricity activity (α, β, θ, δ) and sleep parameters were evaluated before treatment, after treatment and during follow-up. The SPSS generalized linear model statistical method was used to analyze the changes of each evaluation index.Results:Compared with before treatment, the PSQI score of the combination group decreased (7.2±1.7 vs 13.2±2.9), and the improvement was better than that of the rTMS group (9.2±2.5 vs 12.1±2.8) and the drug group (7.5±2.8 vs 11.4±2.9) ( P<0.05). Multiple comparisons results showed that combination group > drug group > rTMS group; and combination group > rTMS group > drug group during follow-up. After treatment and during follow-up, the HAMA and HAMD scores of the rTMS group and the combination group decreased. There was no statistical difference in the improvement rate between the two groups, but they were all higher than the drug group ( P<0.05). After treatment and during follow-up, the β power of the rTMS group and the combination group decreased, and the α power increased, but there was no statistical difference in the δ and θ power. The β, δ and θ power in the drug group increased ( P<0.05), but the α power had no statistical difference. Multiple comparisons results showed that the power of β, δ and θ bands in the rTMS group and the combination group were lower than the drug group, α power was higher than that in the drug group ( P<0.05). Compared with before treatment During follow-up, the sleep latency of the combination group and rTMS group was shorten, and the total sleep time, sleep efficiency, deep sleep (N3) and rapid eye movement (REM) increased( P<0.05), but there was no statistical difference in the changes of sleep parameters in the drug group. Conclusions:rTMS combined with Eszopiclone can significantly improve the sleep quality of patients with chronic insomnia, which is better than that of rTMS and Eszopiclone alone, and it can reduce cortical excitability by regulating brain electrical activity. It can be an ideal treatment for patients with chronic insomnia disorder.
ABSTRACT
Objective: To evaluate the safety and efficacy of a 5 mg sublingual dose of zolpidem, compared to a 10 mg oral dose, at bedtime and "as needed" following middle-of-the-night awakenings. Methods: Participants were randomized into an oral group (oral zolpidem 10 mg and sublingual placebo at bedtime and "as-needed") and a sublingual group (oral placebo and sublingual zolpidem 5 mg at bedtime and "as-needed"). Participants underwent medical evaluation, polysomnography, the psychomotor vigilance test, and completed questionnaires. Results: Of 85 patients, 67 met the criteria for insomnia (48±10 years; 79% women) and were randomized. Of these, 46 completed 92±5 days of treatment. Mild-to-moderate adverse events were reported by 25% of the participants, including headache, sleepiness, and dizziness. Both treatments decreased middle-of-the-night awakenings by an average of -3.1±2.3 days/week and increased total sleep time by 1.5 hours. Changes in sleep quality and insomnia severity scores were also favorable and comparable between groups: variation depended on continuation of treatment. Regarding PSG findings, sleep latency decreased more in the sublingual group than the oral group (-14±42 vs. 10±29 min; p = 0.03). The psychomotor vigilance test showed minor residual effects 30 minutes after awakening, which reversed after 2 hours. Conclusions: The safety and efficacy of both zolpidem formulations are comparable. The sublingual 5 mg dose induced sleep more rapidly. Clinical trial registration: NCT01896336

OBJECTIVE: To investigate the clinical effect of Tongdu Tiaoshen needling in the treatment of chronic insomnia and its mechanism based on the hypothalamic-pituitary-adrenal (HPA) axis. METHODS: A total of 60 patients with chronic insomnia were randomly divided into treatment group and control group, with 30 patients in each group. In addition to the health education on sleep, the patients in the treatment group were given Tongdu Tiaoshen needling, i．e., electroacupuncture at Baihui (GV20), Shenting (GV24), Yintang (EX-HN3), bilateral Shenmen (HT7), and bilateral Sanyinjiao (SP6), and those in the control group were given superficial acupuncture at Shousanli (LI10), Futu (ST32), and Feiyang (BL58) at both sides, once every other day and three times a week for 4 consecutive weeks. Before and after treatment, the Pittsburgh Sleep Quality Index (PSQI) was used to assess the quality and efficiency of sleep, and ELISA was used to measure the serum levels of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT). RESULTS: After treatment, the treatment group had significant reductions in the total PSQI score and the score of each component of PSQI (P<0.01), and the control group had significant reductions in the total PSQI score (P<0.01) and the scores of all components except sleep duration (P<0.05); compared with the control group, the treatment group had significantly lower total PSQI score and the score of each component (P<0.01). After treatment, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.05，P <0.01), and compared with the control group, the treatment group had significant reductions in the serum levels of CRH, ACTH and CORT (P<0.01，P<0.05). CONCLUSION: Tongdu Tiaoshen needling has a good clinical effect in the treatment of chronic insomnia and can significantly improve the sleep condition of patients with chronic insomnia, possibly by reducing the hormones associated with the HPA axis.
ABSTRACT
OBJECTIVE@#To compare the effect on chronic insomnia disorder (CID) and influences on episodic memory and sleep structure between acupuncture and estazolam tablets.@*METHODS@#A total of 140 CID patients were randomized into a meridian-point group (46 cases, 1 case dropped off), a non-meridian-and-non-acupoint group (47 cases, 2 cases dropped off) and a medication group (47 cases, 2 cases dropped off). In the meridian-point group, Baihui (GV 20), Shenmen (HT 7), Sanyinjiao (SP 6), Zhaohai (KI 6) and Shenmai (BL 62) were selected and the routine acupuncture was applied. In the non-meridian-and-non-acupoint group, the needling technique was same as the meridian-point group. Acupuncture was given once daily for 4 weeks in the above two groups. In the medication group, estazolam tablets were administered orally, taken 1 to 2 mg per night, consecutively for 4 weeks. Before and after treatment, the changes in the following indexes were observed in each group, i.e. the score of insomnia severity index (ISI), the score of auditory verbal memory test (AVMT) and the relevant indexes of sleep structure [total sleep time (TST), sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE) and the percentage of non rapid eye movement phase 1, 2 and 3 (N1, N2 and N3) and rapid eye movement time (REM) in TST].@*RESULTS@#After treatment, ISI scores were reduced in the meridian-point group and the medication group (<0.01), the score in the meridian-point group was lower than the medication group and the non-meridian-and-non- acupoint group respectively (<0.01) and that in the medication group was lower than the non-meridian-and-non-acupoint group (<0.01). After treatment, the score of each of immediate recall, short-term delayed recall, long-term delayed recall and delayed recognition of AVMT was increased in the meridian-point group and the medication group respectively (<0.01, <0.05) and the score of each item of AVMT in the meridian-point group was higher than the medication group and the non-meridian-and-non-acupoint group respectively (<0.01, <0.05). The scores of immediate memory and delayed recognition in the medication group were higher than the non-meridian-and-non-acupoint group respectively (<0.01). After treatment, SOL, WASO and N1% were all reduced (<0.01) and TST, SE, N3% and REM% were all increased (<0.01, <0.05) in the meridian-point group and the medication group, N2% in the meridian-point group was reduced (<0.01). After treatment, N1% and N2% in the meridian-point group were lower than the medication group (<0.01) and N3% and REM% were higher than the medication group (<0.01). After treatment, TST, SE and N3% in the meridian-point group and the medication group were all higher than the non-meridian-and-non-acupoint group respectively (<0.01, <0.05) and SOL, WASO and N1% were lower than the non-meridian-and-non-acupoint group respectively (<0.01). REM% in the meridian-point group was also higher than the non-meridion-and-non-acupoint group (<0.01), and N2% in the meridian-point group was also lower than the non-meridian-and-non-acupoint group (<0.01).@*CONCLUSION@#Compared with estazolam, acupuncture much better improves sleep quality and episodic memory in patients with chronic insomnia disorder, which is possibly related to the regulation of sleep structure of patients in treatment with acupuncture.

OBJECTIVES: To investigate the therapeutic effect of cranial electrotherapy stimulation (CES) with sleep hygiene in patients with chronic insomnia. METHODS: This study was designed as a prospective, double-blinded, and randomized controlled trial. Twenty-seven patients with chronic insomnia were recruited and randomly allocated to two groups; cranial microcurrent therapy (MC) group and sham group. All patients received sleep hygiene education. Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were measured at baseline (pre-treatment), and 2 weeks and 4 weeks of treatment. RESULTS: In MC group, the PSQI and ISI showed a tendency to decrease consistently until 4 weeks of treatment. In sham group, PSQI and ISI initially decreased during the first 2 weeks, but it increased after 2 weeks of treatment. CONCLUSIONS: This study showed that combination treatment of CES and sleep hygiene is more effective in treating chronic insomnia than sleep hygiene only as demonstrated by improvement and maintenance of sleep score for 1 month.

Objective:To explore the effect of Taiji Quan on the sleep quality of patients with chronic insomnia disorder (CID) and its mechanism. Methods:From January, 2015 to December, 2017, 31 patients with CID were enrolled in the sleep disorder clinic. Before and 24 weeks after Taiji Quan exercise, the Pittsburgh Sleep Quality Index (PSQI) was used to assess their sleep quality, the serum levels of tumor necrosis factor (TNF)-α, TNF-β, soluble tumor necrosis factor receptor (sTNF-R)1 and sTNF-R2 were detected with protein chip, and the correlation between the total score of PSQI and the serum levels of TNF-α, TNF-β, sTNF-R1 and sTNF-R2 were analyzed after exercise. Results:After Taiji Quan exercise, the scores of PSQI factors (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, daytime dysfunction) and the total score of PSQI decreased (t > 4.080, P < 0.05). The serum levels of TNF-α and TNF-β decreased (t > 13.580, P < 0.01), however, the serum levels of sTNF-R1 and sTNF-R2 significantly increased (t > 160.189, P < 0.001). The serum levels of TNF-α and TNF-β were positively correlated with the total score of PSQI (r > 0.638, P < 0.001), while the serum levels of sTNF-R1 and sTNF-R2 were negatively correlated with the total score of PSQI (r > 0.532, P<0.001). Conclusion:Taiji Quan exercise could help to improve the sleep quality of patients with CID. The mechanism may be related to the decrease of the serum levels of TNF-α and TNF-β, and the increase of the serum levels of sTNF-R1 and sTNF-R2.
ABSTRACT
Objective To investigate the clinical features of chronic insomnia patients with cerebral small vessel disease (CSVD). Methods This cross-sectional study consecutively enrolled one hundred out-patient and in-patient patients meeting the diagnostic criteria of chronic insomnia at the department of psychiatry and neurology in tlie third affiliated hospital, Sun Vet-sen University from January 2018 to April 2019.Tlie patients (52-75 years) received magnetic resonance ( MR) .polysomnography ( PSG) , Montreal Cognitive Assessment (MoCA) in two weeks after enrollment. The subjective symptoms were evaluated by visual analogue scale ( VAS). Patients with comorbid CSVD were in the experimental group (28cases) .while those with simple insomnia were in the control group (72 cases). 11 ie differences of symptoms,I∗SC parameters and cognitive function between the two groups were compared. Results In the experimental group, only dizziness of subjective symptoms was higher than that in the control group (7. 0 [4. 5,8. 0] vs. 4. 0 [2. 0, 6. 0] ). The experimental group also had higher PSC monitored awakening time after sleep (105. 8 [66. 7, 141.3] min to 70. I [35.4,116.8] min) .arousal index ([29 ±8] limes/h vs. [21 ±6] times/h) , ratio of nonrapid eye movement sleep 1 phase ([15 ±4] % vs. [ 10 ±3] %) than the control group,but lower sleep efficiency ([67 ± 18] % vs. [75 ± 15] % ). The total MoCA score (19.0 [15.0,24.0] to 23.5 [ 17.0,26. 5]) .visuospatial score (2.0 [ 1.0,3.0] vs. 2. 5 [ 1.5,3.0]) .executive function score (2.0 [ I. 0,3.0] vs. 2.5 [2.0,3.0]) and short-term memory score (2. 5 [ I. 0,4.0] vs. 3. 0 [2.0,4. 0]) in the study group were significantly lower than that in the control group (/' <0. 05). Conclusion Chronic insomnia with CSVD is common with concealing subjective symptoms,and it needs to be identified from the aspects of cognitive assessment and sleep monitoring.
ABSTRACT
BACKGROUND: To investigate the sleep disorders related to chronic insomnia and compare the characteristics of each group. METHODS: We registered 191 patients (female 56.0%, age 61.7 years) who have complained about symptoms of insomnia for more than three months and assessed sleep disorders related chronic insomnia by analyzing their polysomnography (PSG) parameters, demographics, and questionnaires (Insomnia Severity Index, Beck Depression Inventory, Pittsburg Sleep Quality Index, and Epworth Sleepiness Scale, and World Health Organization Quality of Life Assessment Instrument abbreviated version). RESULTS: Patients were categorized into groups of primary insomnia (PI, 51.8%, n=99), comorbid insomnia with obstructive sleep apnea (CIO, 38.7%, n=74), and comorbid insomnia with periodic limb movement disorder (CIP, 9.4%, n=18). CIO was older and more obese than PI and CIP. The proportion of males was the highest in CIO. Arousal index of PSG was higher in CIO and CIP than in PI. Other parameters and the results of questionnaires were not different among groups. CONCLUSIONS: About a half of patients with chronic insomnia symptoms (48.2%) had considerable sleep disorders associated with insomnia. Our study suggests that the PSG as well as history taking and demographics are necessary to clarify the relevant conditions of chronic insomnia disorder for appropriate treatment.

OBJECTIVES: To assess the effect and safety of transcranial direct-current stimulation (tDCS) in primary chronic insomnia. METHODS: A one-month, double-blind, randomized, sham-controlled trial was performed. A total of 7 patients with primary chronic insomnia received tDCS using anodal (n=3), cathodal (n=2), or sham stimulation (n=2). They were followed up at 1 week and 1 month after treatment. The primary outcome measures included improvement in total sleep time (TST), sleep latency (SL), and sleep efficiency (SE) at 1 month follow-up. RESULTS: TST and SE were improved with tDCS at 1 month follow-up in all patients (100%) of the anodal group, one (50%) of the cathodal group, and one (50%) of the sham group. tDCS improved SL at 1 month follow-up in two patients (67%) of the anodal group, one (50%) of the cathodal group, and none (0%) of the sham group. With respect to adverse events, transient itching sensation occurred in one patient of the anodal group. None of the other groups reported adverse events. CONCLUSIONS: Our results suggest that tDCS may be effective and safe for treatment of primary chronic insomnia. A larger controlled study needs to be further investigated.

Objective To observe the efficacy and safety of Shenqiwuweizikeli for treating chronic insomnia.Methods One hundred and ninety-six cases of subjects were randomly divided into Shenqiwuweizikeli group (n =98) and Estazolam tablets group (n =98).The pittsburg sleep quality index (PSQI) was adopted to evaluate the clinical effects and records of adverse reactions during the study period.Also the lab routine inspection(blood routine,urine routine,liver and kidney function, electrocardiogram were conducted to evaluate safety.Results The Shenqiwuweizikeli and Estazolam tablets all had significant effects for chronic insomnia.The total effective rate of Shenqiwuweizikeli group was 92.86％ (91/98), of Estazolam tablets group was 93.88％(92/98) ,and there was no significant difference (P＞0.05).There were no abnormalities in terms of each routine inspection index.After stopping take the medicine, The adverse reactions including bounce sex insomnia(60 cases), daytime sleepiness/drowsiness (55 cases), dizziness with lacking of power and light headedness(23 cases) in Estazolam tablets group were all more than Shenqiwuweizikeli group with significant difference(P＜0.01).Conclusion The Shenqiwuweizikeli has definite efficacy and safety for treated with chronic insomnia without withdrawal of recoil and dependence.
ABSTRACT
<p><b>INTRODUCTION</b>Chronic insomnia is associated with many physical and psychiatric illnesses, and its underlying aetiology needs to be identified in order to achieve safe and effective treatment. Obstructive sleep apnoea (OSA) and periodic limb movement disorder (PLMD) are common primary sleep disorders that can lead to chronic insomnia. Patients with these conditions are evaluated using polysomnography (PSG).</p><p><b>METHODS</b>The PSG records of 106 patients with chronic insomnia who presented to a multidisciplinary sleep clinic in Singapore over a five-year period were reviewed. To examine the utility of PSG in the evaluation of chronic insomnia, the clinical diagnoses of the patients before and after the sleep studies were compared.</p><p><b>RESULTS</b>Among the 106 patients, 69 (65.4%) were suspected to have primary sleep disorders based on clinical history and examination alone. Following PSG evaluation, 42.5% and 4.7% of the study population were diagnosed with OSA and PLMD, respectively. OSA was found in 35.9% of the 39 patients who had underlying psychiatric conditions.</p><p><b>CONCLUSION</b>This study illustrates that many patients with chronic insomnia have underlying primary sleep disorders. It also highlights the danger of attributing chronic insomnia in psychiatric patients to their illness, without giving due consideration to other possible aetiologies. Clinicians should maintain a high index of suspicion for the presence of other aetiologies, and make timely and targeted referrals for sleep studies where appropriate.</p>

Introducción: el insomnio, especialmente cuando se cronifica, se convierte en una patología con marcadas implicaciones en la salud física y mental. No obstante su importancia, en nuestro país existen pocos estudios poblacionales sobre su comportamiento epidemiológico. Estudios previos realizados en el departamento de Caldas mostraron una elevada prevalencia de insomnio global con cifras alrededor de 47%. Objetivo: establecer la frecuencia, características sociodemográficas y persistencia a dos años del insomnio crónico, en una muestra poblacional representativa de la ciudad de Manizales. Sujetos y métodos: estudio transversal mediante entrevista domiciliaria en diferentes estratos socioeconómicos en mayores de 18 años, con queja de insomnio en el estudio previo de trastornos de sueño en Caldas (2008), que incluyó 530 personas de las cuales 228 tenían insomnio (agudo o crónico), lo cual arrojó una prevalencia global de 43.9%. Para el análisis de la información se empleó el paquete estadístico Epiinfo 6.04d/. Resultados: el seguimiento a dos años se pudo realizar a 218 personas, y de éstas el insomnio continuaba en 175, lo cual indicó una prevalencia de insomnio crónico de 33% y una persistencia del mismo de 80.2%. Cuando sólo se estimó el insomnio con repercusión diurna la prevalencia fue de 10.9%. En más de la mitad de los individuos el insomnio había estado presente entre cinco y diez años. El aumento en edad fue el único factor asociado para una mayor frecuencia. A pesar de la persistencia y severidad del insomnio, sólo 18.3% lo habían informado al médico. Conclusiones: las prevalencias halladas de insomnio global, crónico y con repercusión diurna se encuentran entre los rangos mencionados en la literatura y se detectó una elevada persistencia y duración del insomnio crónico. Lo anterior, y dadas sus consecuencias negativas sobre individuos y comunidades, amerita una búsqueda activa de esta condición en la práctica clínica y medidas gubernamentales apropiadas para su prevención y manejo (Acta Med Colomb 2011; 36: 119-124).
Introduction: insomnia, especially when it becomes chronic, it becomes a disease with marked implications for physical and mental health. Despite its importance, in our country there are few population studies on the epidemiological pattern. Previous studies in the Department of Caldas showed a high overall prevalence of insomnia with figures around 47%. Objective: To establish the frequency, demographic characteristics and persistence to two years of chronic insomnia in a population sample representative of the city of Manizales. Subjects and Methods: A cross-sectional household interviews in different socioeconomic levels in subjects over 18 years, complaining of insomnia in the previous study of sleep disorders in Caldas (2008) that included 530 people of which 228 were insomnia (acute or chronic), yielding an overall prevalence of 43.9%. For data analysis we used the statistical package EpiInfo 6.04 /. Results: The 2-year follow-up could be performed and of these 218 people remained in 175 insomnia, which indicated a prevalence of chronic insomnia of 33% and a persistence of the same of 80.2%. When only considered daytime consequences of the insomnia, the prevalence was 10.9%. In more than half of those insomnia had been present between five and ten years. Increasing age was the only factor associated to a higher frequency. Despite the persistence and severity of insomnia, only 18.3% had reported to the doctor. Conclusions: The overall prevalence of insomnia, chronic and daytime impact are found within the ranges reported in the literature and found a high persistence and duration of chronic insomnia. Above, and given its negative consequences on individuals and communities, warrants an active search for this condition in clinical practice and appropriate government measures for its prevention and management (Acta Med Colomb 2011; 36: 119-124).
ABSTRACT
Objective To study the clinical effect of acupuncture therapy combining with biofeedback therapy on senile chronic insomnia patients. Methods 150 cases of senile chronic insomnia were divided into 3groups randomly: group A received acupuncture therapy only, group B received biofeedback therapy only, and group C received both therapies. The scores of Pittsburgh Sleep Quality Index (PSQI) ,sleep efficacy,sleep latency, total sleep time and the scores of Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD-17) were assessed before the treatment and at the end of the 4th and 8th week during the treatment.Results After 8 weeks treatment, the scores of PSQI, sleep efficacy, sleep latency, total sleep time and the scores of HAMA and HAMD-17 of group C((7.92 ±2.59)score,(82.52 ±8.93)% ,(24.06 ±8.23)minutes,(413.75± 42.41) minutes, (9.63 ± 3.75) score, (10.10 ± 3.27) score) were better than that of group A (( 9.51 ± 2.92)score, (79.06 ± 10.70) %, (33.16 ± 11.31) minutes, (373.47 ± 40.65) minutes, (15.08 ± 4.20) score, (14.33±± 3.56) score) and group B (( 11.46 ± 3.75) score, (68.85 ± 12.34) %, (33.65 ± 11. 38) minutes, (281.88 ±38.02) minutes, (11.63 ± 4.15) score, (12.08 ± 4.08) score) significantly (P ＜ 0.01). Conclusion The therapy of acupuncture combining with biofeedback is benefit to improve the sleep quality of senile chronic insomnia patients,meanwhile the anxiety and depression associated with insomnia can be improved.
