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
Confusional arousal (CA) is a rare non-rapid eye movement sleep-related parasomnia and rarely reported in China, leading to misdiagnosis and mistreatment in clinic. A detailed collection of clinical symptoms and simultaneous video polysomnography is very important for diagnosis and differential diagnosis of CA. A elderly patient with CA was diagnosed according to the International classification of sleep disorders, third edition diagnostic criteria. The summary and analysis of the patient is conducted to improve the understanding of CA, meanwhile to avoid misdiagnosis and mistreatment.
ABSTRACT
Objective@#To explore serum levels of brain-derived neurotrophic factor (BDNF) and glial-derived neurotrophic factor (GDNF), and whether changes of BDNF and GDNF are correlated with sleep quality and cognitive function in patients with chronic insomnia disorder (CID).@*Methods@#Fifty-seven CID patients in the Department of Sleep Disorders, Chaohu Hospital of Anhui Medical University and 30 healthy controls were enrolled from May 2017 to July 2018. Pittsburgh Sleep Quality Index (PSQI) was used to assess the degree of insomnia severity (some CID patients were monitored by overnight polysomnography). Montreal Cognitive Assessment (MoCA) scale and Nine-Box Maze were used to assess general cognitive function and specific memory function, respectively. The serum levels of BDNF and GDNF were detected using ELISA.@*Results@#Compared to the controls, CID patients had significantly higher PSQI scores (CID patients: 14.0±2.2, healthy controls: 3.9±1.1; t=28.093, P<0.01), lower MoCA scores (CID patients: 24.5±3.6, healthy controls: 26.5±0.9; t=-2.985, P<0.01), more errors in object working memory (CID patients: 1.0 (0, 1.0), healthy controls: 0 (0, 0.3)), spatial working memory (CID patients: 3.0 (2.0, 4.0), healthy controls: 1.0 (1.0, 2.0)) and object recognition memory (CID patients: 0 (0, 0), healthy controls: 0 (0, 0); Z=-2.896、-5.007、-2.306, P<0.05), and lower serum BDNF (CID patients: (19.48±7.50) ng/ml, healthy controls: (46.49±13.33) ng/ml; t=-10.274, P<0.01) and GDNF (CID patients: (32.76±14.04) pg/ml, healthy controls: (59.63±20.30) pg/ml; t=-7.240, P<0.01). The partial correlation analysis showed that in the CID patients, the levels of BDNF and GDNF were correlated with PSQI scores negatively (r=-0.293, -0.320, P<0.05) and MoCA scores positively (r=0.331, 0.295, P<0.05). The BDNF level was also correlated with the duration of disease and the errors in the spatial working memory test negatively (r=-0.319, -0.393, P<0.05), and the GDNF level was correlated with the total sleep time detected with polysomnogram positively (r=0.520, P<0.05).@*Conclusion@#Serum BDNF and GDNF levels in CID patients were lower than those in healthy controls, and correlated with sleep quality and cognitive impairment.

ABSTRACT
Objective:To explore the changes of serum levels of copeptin and α-amylase and their correlations with sleep and cognition in patients with chronic insomnia (CI).Methods:From September 1, 2018 to May 31, 2019, fifty CI outpatients or inpatients from the Department of Sleep Disorder, Affiliated Chaohu Hospital of Anhui Medical University, were enrolled continuously, and thirty good sleepers from the Physical Examination Center of the hospital, were also enrolled to serve as controls. Pittsburgh Sleep Quality Index (PSQI), polysomnography (PSG) and Pre-Sleep Arousal Scale (PSAS) were used to assess the insomnia severity and sleep disorder susceptibility. Montreal Cognitive Assessment scale (MoCA) and Nine-Box Maze were used to respectively assess general cognition and memories. The serum levels of copeptin and α-amylase were detected using enzyme linked immunosorbent assay.Results:Compared to the controls, the CI patients had increased PSQI score (16.0 (15.0, 17.0) vs 4.0 (2.8, 6.0); Z=-7.678, P<0.001) and PSAS score (33.0 (30.0, 37.5) vs 17.0 (16.0, 18.5); Z=-7.350, P<0.001), decreased MoCA score (24.1±2.5 vs 26.7±1.9, t=-4.625, P<0.001), increased numbers of errors in the object working (1.0 (0, 1.0) vs 0 (0, 1.0), Z=-2.099, P=0.036), spatial working (2.0 (1.0, 4.0) vs 1.0 (0, 2.0), Z=-3.935, P<0.001) and object recognition (1.0 (0, 2.0) vs 0 (0, 0), Z=-2.266, P=0.023) memories, and elevated serum levels of copeptin ((35.1±19.9) pg/ml vs (14.8±6.9) pg/ml, t=5.414, P<0.001) and α-amylase ((990.1±193.7) U/L vs (728.9±230.5) U/L, t=5.597, P<0.001). In the CI patients, the level of copeptin was positively correlated with PSQI score ( r=0.338, P=0.013), PSAS score ( r=0.316, P=0.021), sleep latency ( r=0.324, P=0.018), number of awake ( r=0.325, P=0.017) and stage 1 percent of non-rapid eye movement sleep ( r=0.278, P=0.044), and negatively correlated with stage 2 percent of non-rapid eye movement sleep ( r=-0.279, P=0.043); α-amylase was positively correlated with numbers of awake in PSG ( r=0.293, P=0.033). Multiple linear regression analysis showed that copeptin level affected PSQI score (β=0.255, P=0.043) and sleep latency (β=0.254, P=0.043). Conclusion:The levels of copeptin and α-amylase in CI patients elevate, and copeptin may be associated with initial sleep difficulties, but not with cognitive ability, in patients with CI.

ABSTRACT
The growing evidence suggests that adenosine system can regulate sleep-wake through the cooperation between inhibition of promoting wake system and excitement of promoting sleep system.Changes in adenosine level and adenosine receptor activity by pharmacological and genetic methods can affect sleep time and structure.However,the studies on whether the changes exist in the adenosine system in the patients with chronic insomnia disorder remain rare.In order to arouse the close attention to the clinical sleep study of adenosine system,in this paper,we present an overview of the current research progress regarding adenosine in general knowledge (adenosine's production,metabolism,peripheral distribution,circadian rhythm),the regulation of sleep and its mechanism,and the differences in regulation of sleep for various adenosine receptors.In the end,we propose some research directions of adenosine system under chronic insomnia after pointing out the existing issues currently.
ABSTRACT
Objective To summarize the distribution of departments,conditions of diagnosis and treatment of the syphilis patients in the general hospitals,and thus to improve the level of diagnosis and treatment.Methods A retrospective analysis of epidemiology and clinical data of 282 cases with syphilis in recent 5 years were conducted. Results The ratio of male to female was about 1:1.9.Female showed a high incidence in the 21 -50 years old,aver-age (41.68 ±0.96)years old,but for male in the 41 -70 years old,average (53.25 ±1.59)years old.The cases combined with other infectious diseases accounted to 22.0 % (62/282).The cases from the department of obstetrics and gynecology were the most (106 cases),followed by surgery (86 cases)and internal medicine (49 cases).Only 23 cases showed the clinical manifestations of syphilis in the 79 cases,which must be treated.The test rate of TRUST was only 39.0% (110/282).Furthermore,it was very low for the rate of treatment and standard treatment. Conclusion Syphilis is the most in department of obstetrics and gynecology in general hospital,and it is also com-mon in the surgery and internal medicine.The most prominent problems are that the non-special doctors had weak awareness for definite diagnosis of syphilis,and the low rate of treatment and standard treatment.
ABSTRACT
Objective To explore the differences of memory functions and objective sleep parameters and their correlations in patients with insomnia disorder in different subtypes.Methods Eightynine patients with insomnia disorder,including 11 patients with difficulty initiating sleep(DIS),20 patients with early morning awakening(EMA),20 patients with difficulty maintaining sleep (DMS) and 38 patients with mixed sleep symptoms(MS) were enrolled between August 2012 and February 2014 in the Memory and Sleep Disorders Clinic of the First Affiliated Hospital of Anhui Medical University.Memory functions,including objective memory,spatial memory,working memory and reference memory were detected with nine boxes maze,and objective sleep profiles were assessed using polysomnography.Results The error numbers of spatial(H =15.404,P =0.002) and working (H =10.126,P =0.018) memories were significantly different among the 4 subtypes of patients,with more errors of spatial and working memory in the EMA (6.00 (5.00,8.00),5.00 (4.00,6.00)) and MS (5.00 (3.75,7.25),5.00 (2.75,7.00)) groups compared with the DMS (2.50 (2.00,4.00),2.00 (1.00,4.00)) group (tspstial =3.938,3.428;t =2.803,2.840;all P ＜ 0.05).Sleep efficiency(H =7.929,P =0.048),REM sleep time(F =2.840,P =0.043) and the percentage of REM sleep time on total sleep time (REM％;H =7.913,P =0.048) were also significantly different among the 4 subtypes of patients,with lower sleep efficiency in the MS(69.7％ (50.5％,78.7％)) group compared with the EMA (81.0％ (64.8％,86.4％)) and DMS (80.2％ (62.6％,88.9％)) groups (t =2.242,2.352;all P ＜ 0.05),less REM sleep time (min) and REM％ in the EMA(61.6 ±27.1,16.9％ (13.1％,21.9％)) and MS(56.9 ±31.4,16.9％ (11.5％,21.2％)) groups compared with the DMS (80.9 ± 32.7,22.3％ (18.5％,25.5％)) group (qREM time =3.791,5.397;tREM％ =2.513,2.612;all P ＜0.05).The error numbers of working memory and spatial memory negatively correlated with the REM sleep time (r =-0.387,-0.348;all P ＜ 0.05) and REM％ (r =-0.350,-0.354;all P ＜ 0.05).Conclusions There are discrepancies in the spatial and working memories and subtle differences in the objective sleep parameters among the patients with different subtypes of insomnia disorder.The worse memories in insomnia disorder patients might be associated with the decreased REM sleep.
ABSTRACT
Objective To explore changes of procedural memory in patients with primary insomnia(PI) and its characteristics.Methods Thirty-six PI patients and 36 controls were enrolled.The procedural memory was respectively detected with category exemplar generation and motor sequence tasks,and the declarative memory was assessed by free recall task.Results Compared with the controls,PI patients showed few correct numbers in the category exemplar generation (7.0 (6.0,8.8) vs 9.0 (9.0,11.0),Z=5.537,P＜0.01) and motor sequence task (8.0±3.3 vs 11.5 (8.6,13.8),Z=4.152,P＜ 0.01)and the phases of immediate recall (3.0 (2.3,4.0) vs 6.0 (5.0,7.0),Z =6.479,P ＜ 0.01),delayed recall (9.0 ± 2.2 vs 11.0 (10.0,12.0),Z =4.747,P ＜ 0.01) and delayed recognition (15.0 (13.0,15.0) vs 15.0 (15.0,15.0),Z=4.637,P＜0.01) of the free recall task.Furthermore,the early morning awakening group had significantly lower correct numbers in the motor sequence task,the delayed recall and recognition phases of the free recall task than the difficulty initiating and maintaining sleep groups.Conclusion The procedural and declarative memories are impaired in the PI patients,especially the early morning awakening insomniacs.
ABSTRACT
ObjectiveTo explore alterations of serum levels and clinical significance of corticotropin releasing hormone (CRH), thyrotropin releasing hormone (TRH) and gonadotropin releasing hormone (GnRH) in patients with fibromyalgia (FM). MethodsA total of 55 subjects participated in this study: 29 healthy volunteers and 26 patients with FM recruited from Department of Neurology, the First Affiliated Hospital of Anhui Medical University from June 2009 to October 2010.The depression rate was assessed by Hamilton Depression Rating Scale-17. ELISA was used for the detection of the serum levels of CRH, TRH and GnRH.Normal distribution quantitative data were described by the (-x) ± s and tested by independent sample t-test. Non-normal quantitative data were described by interquartile range and tested by independent Mann-Whitney.The diagnostic specificity and sensitivity of 3 kinds of hormones test were analyzed by receiver operator characteristic ( ROC ) curve, and the Spearman correlation was used for analysis of hormone levels and age, gender, tenderness, pain degree and depression severity.Results Compared with the control (70. 0(48.7,78.0) ng/L), the fibromyalgia patients had obviously increased CRH (271.9 (210.9,326.5) rg/L, x2 =6.408, P＜0. 01) , and significantly higher TRH ((82.7 ±6. 9 ) ng/L vs ( 87. 2 ± 6. 8 ) ng/L, t = 2. 560, P ＜ 0. 05, respectively) and GnRH ( ( 18. 2 ± 0. 9 ) ng/L vs ( 19. 9 ± 1.6)ng/L,t =5. 324, P ＜0. 01, respectively). The serum concentrations of the CRH, TRH and GnRH were positively correlated with pain intensity and numbers of tenderness respectively, and those of the CRH and GnRH were positively correlated with depressive degree either. The areas under the ROC curve in the CRH, TRH and GnRH, evaluating the sensitivity and specificity for diagnosis of fibromyalgia, were respectively 1. 000, 0. 684 and 0. 854. ConclusionsThe FM patients had an increased secretion of CRH,TRH and GnRH. CRH might serve as the adjunctive criteria for the diagnosis of FM.
ABSTRACT
Objective To explore memory function affected by chronic insomnia. Methods Fiftyfive patients with primary insomnia (PI), 119 patients with comorbidity of depression and insomnia (CDI)and 50 normal individuals were enrolled. Objective memories, including spatial working memory, spatial reference memory, objective working memory and object reference memory, were detected by nine boxes maze, and subjective memory was assessed by themselves on a 5-point scale ranging from 0 ( extremely severe problem) to 4 (no problem). Results Compared to the controls, the self-evaluated memory ( 1( 1,2 ) ) was worse in the mild PI patients, and the spatial working memory ( 6 ( 2. 5,11 ) ) was also worse in the severe PI patients( ×2 = 4. 526,3. 529, both P ＜ 0. 01 ). For the CDI, the self-evaluated memory ( 2 ( 1,2) ) and spatial working memory (6(3,10)) were worse in the mild patients(×2 =5. 803,4. 155 ,both P ＜0. 01 ). However, the object ( 0. 5 (0,1) ) and spatial reference ( 1.5 ( 1, 3 ) ) memories were also worse in the severe patients ( ×2 =2. 641,3. 955 ,both P ＜0. 01 ). Conclusions PI damages subjective memory and the severe PI also damages spatial working memory. CDI damages various memory functions, especially in severe CDI patients, including subjective memory, object reference memory, spatial reference memory and spatial working memory.
ABSTRACT
Objective To investigate the association between the plasma level of fibrinogen and carotid atherosclerosis(CAS)in patients with ischemic cerebrevascddar disease(ICVD),and the effects intensity of different risk factors on CAS.Methods Carotid intima-media thickness(IMT)was measured by color Doppler uhrasonography in 840 patients with ICVD,including cerebral infarction(ci),transient ischemic attack and insufficient blood-supply of vertebral-basilar artery.According to the results of uhrasonography,the patients were divided into four groups:normal(IMT≤0.9 mm),arterial sclerosis (0.9 mm<IMT≤1.5 mm),plaque(IMT>1.5 mm)and stenosis(stenosis of lumina≥30%).The plasma fibrinogen and other biochemical markers were also detected.The history of hypertension,diabetes,hyperlipemia,smoking,drinking were recorded,and the blood pressure was measured.Results The level of fibrinogen was the highest((3.91±1.05)g/L)in the patients with CI,the difference was significant compared to the patients with TIA((3.45±0.81)S/L,X2=62.812,P<0.01),and so was the prevalence of CAS(77.0%),there was significant difference compared to the patients with TIA(61.8%,X2=9.000,P<0.01).The rate of CAS increased gradually with the quartiles of the fibrinogen(the odds ratios in the 2nd,3rd and 4th quartiles(3.16-3.72 g/L,3.72-4.39 g/L and>4.39 g/L)were 1.80,3.36 and 3.38 respectively,all P≤0.01).There were significant differences of age,fibrinogen,systolic blood pressure,hyperglycaemia and history of diabetes and hypertension between the normal-carotid group and three CAS groups.Multiple logistic regression showed that only the age,fibrinogen and systolic blood pressure significandy influenced on the CAS with the highest risk factor being the fibrinogen.Conclusions In the patients with ICVD,the elevated plasma fibrinogen Was significantly correlated with CAS,and misht play more important role than other traditional risk factors.

ABSTRACT
BACKGROUND: Vascular complications usually occur in diseases related to obesity such as primary hypertension or diabetes. Treating obesity with the method of promoting blood circulation to remove blood stasis gains a curative effect, so we presume that obesity may be correlated to blood stasis syndrome.OBJECTIVE: Analyzing the relationship between leptin(Lep) and insulinmetabolism of sugar and fat,endothelin(ET),blood pressure,body mass index(BMI), etc. Comparison of the differences in Lep and BMI between the blood stasis syndrome group and the non-blood stasis syndrome group was conducted to explore the correlation between obesity and the blood stasis syndrome.DESIGN: An observatory and controlled study based on patients with hypertension or diabetes.SETTING: Wards of the department of dardiovascular dedicine and the department of dndocrinology of a university of traditional Chinese medicine.PARTICIPANTS: All the patients in the present study were hospitalized at the Department of Internal Medicine of the Second Affiliated Hospital(Jinan City, Shangdong Province) of Shandong University of Traditional Chinese Medicine from September 2000 to January 2001.Among them, 126 cases with hypertension were at the Department of Cardiovascular Medicine, and 133 cases with type 2 diabetes were at the Department of Endocrinology. Inclusion criteria: ① The diagnosis of diabetes followed the diagnostic criteria for diabetes that was formulated by the WHO in 1980; ② The diagnosis of hypertension followed the diagnostic criteria in"China' s Guidebook for Hypertension Prevention and Treatment." The patients were aged between 45-76 years. Exclusion criteria: ① Secondary hypertension,diabetics; ②Complicated with severe diseases; ③ Complicated with severe disfunction of the heart,lung,liver, kidney or severe primary diseases in hematopoietic system; ④ Patients with mental disorder or pregnant women or in the state of lactation; ⑤ Patients aged <45'years old or>76 years old; ⑥ Patients who refused to participant in the study. Eighty-four cases with primary hypertension and 85 diabetics met the inclusion criteria, with a total of 169 cases including 73 male cases and 96 female cases. The cases were divided into blood stasis syndrome group and non-blood stasis syndrome group according to the clinical symptoms. There were 23 male cases and 37 female cases in the blood stasis syndrome group.METHODS: Drawing vein blood at the state of empty stomach for making plasma and serum. ET was detected with the radioimmuoassay(RIA) kit of ET by the method of RIA(the Arithmometer of Amma5500γ) . Lep and Ins were detected with the radioimmuoassay(RIA) kit of Lep and the radioimmuoassay(RIA) kit of Isu. The fasting blood sugar, total cholesterol(TC),triamid-glycerin(TG), high dense lipoprotein-cholesterol(HDL) and low dense lipoprrotein-cholesterol(LDL) were detected by the full-automatic bio-chemical analytical instrument of AMS-SaBa/8.MAIN OUTCOME MEASURES: Comparing the difference of Lep,Ins,ET between different diseases,syndromes; analyzing the relationship between Lep and Ins,BMI,blood sugar,blood lipid,blood pressure,etc.RESULTS: The detectable rate of the blood stasis syndrome in the diabetes group was higher than that in the hypertension group (P<0.05) . The ET density,Lep density,BMI,the percentage of fat of the blood stasis syndrome group were higher than those of the non- blood stasis syndrome group (P<0.05 ). The Ins density of the blood stasis syndrome group was lower than that of the non-blood stasis syndrome group(P<0.01 ). There was a positive correlation between Lep and BMI,the percentage of fat,ET,systolic pressure (SP),pulse pressure(PP) (P<0.05 or P<0. 01).CONCLUSION: There was a positive correlation between obesity and the blood stasis syndrome. Lep of patients with type 2 diabetes or hypertension was positively correlated to BMI,the percentage of fat and the level of ET.
ABSTRACT
The authors have studied the changes in the concentration of glutathione of the red blood cell (RBC-GSH) and plasma malondialdehyde (MDA) in 54 patients with acute brain stroke. The results indicated that the concentration of RBC-GSH reduced obviously and that of plasma MDA increased markedly within 72 hours after illness. However, there is no obvious difference between the cases of hemorrhagic cerebrovascular diseases and cerebral infarction group. The RBC-GSH level rised again in the 7th day, while the plasma MDA still remained higher level, they were normal during the convalescent period. The pathological basis of the change may be the response of the free radicals in human body.
ABSTRACT
Objective: To investigate the clinical effect of Naofuqing Capsules on senile dementia. Methods: 30 patients with senile dementia were treated with Naofuqing Capsules and the curative results were compared with that of the control group 30 cases. Results: The results showed that the integral titres of MMSE and HDS R of groups increased obviously after treatment( P 0.05). The total effective rates were 83.3% and 80.0%,respectively. No obvious difference was observed in clinical effect between two groups. Conclusion: Naofuqing Capsules possesses a definite therapeutic effect for senile dementia.
