Objective:To investigate the relations among entertainment screen-based sedentary behavior,edu-cational sedentary behavior,and inhibitory control in school-aged children.Methods:A total of 700 Chinese school-aged children(10-15 years old)were recruited.The Adolescent Sedentary Active Questionnaire was used to assess total sedentary time,entertainment screen-based sedentary time,and educational sedentary time.Executive function was measured by the Stroop task.Results:There were significantly negative associations between entertainment screen-based sedentary time and the accuracy of Stroop task in the congruent and incongruent condition(β=-0.15,-0.18),while there was significantly positive association between educational sedentary time and the reac-tion time of Stroop task in the incongruent condition(β=-0.09).Conclusion:The relationship between sedentary behavior and inhibitory control may vary depending on the type of sedentary behavior.Moreover,special emphasis should be placed onlimiting the entertainment screen-based sedentary behavior to promote cognitive development in school-aged children.

Objective To explore the state of cardiac autonomic nerve function in schizophrenia patients with metabolic syndrome and analyze its influence factors and to reduce the occurrence of sudden cardiac death of the patients. Methods A total of 168 cases of patients according with the ICD-10 schizophrenia diagnostic criteria were divided into group A(78 cases of schizophrenia with metabolic syndrome),group B(90 cases of schizophre-nia without metabolic syndrome)and another 92 normal cases were included as control group(group C). Twenty-four hours dynamic electrocardiogram was conducted respectively and the heart rate variability (HRV) was ana-lyzed. Results Values of LF,HF,SDNN,SDANN,RMSSD and PNN50 in group A and group B were much low-er than those in group C and they were statistically significant(P < 0.05). Values of LF,HF,SDNN,SDANN, RMSSD and PNN50 in group B were much higher than those in group A and they were statistically significant(P<0.05). Excluding the influence of schizophrenia ,logistic regression analysis showed that the influence factors of HRV values were course of the disease(OR = 1.864,95%CI 1.110~3.128),age(OR = 1.170,95%CI 1.018~2.491),types of antipsychotic drugs(OR=2.419,95%CI 0.976~1.835),abdominal obesity(OR=2.425,95%CI 1.347~4.366),blood pressure value(OR=1.263,95%CI 1.575~3.937),blood glucose value(OR=3.376, 95%CI 1.359~2.923)and blood lipid value(OR = 2.178,95%CI 1.492~6.756). Conclusions Schizophrenia patients with metabolic syndrome have obvious cardiac autonomic nerve dysfunction. Excluding the influence of schizophrenia itself,the other possible risk factors include course of the disease,age,types of antipsychotic drugs,abdominal obesity,blood pressure value,blood glucose value and blood lipid value.

Objective To understand the job burnout status of bank staff and analyse the relationship between job burnout and self-efficacy,job satisfaction.Methods The job burnout,self-efficacy and job satisfaction of 8 942 bank staff was surveyed by Maslach burnout inventory-general survey(MBI-GS),general self-efficacy scale (GSES) and job satisfaction scale (JSS) respectively.Results A total of 8 942 questionnaires were issued and 7 486 valid questionnaires were returned.The score of self-efficacy in male was significantly higher than that in the female(P ＜0.05).There was no significant difference in job satisfaction score between male and female(P ＞ 0.05).The score of emotional exhaustion (EE) in female was significantly higher than that in male,while the score of reduced personal accomplishment(RPA) was significantly lower than that in male (P ＜ 0.05);there was no significant difference in depersonalization (DP) score between male and female (P ＞ 0.05).The EE,DP and PAL scores of bank staff with post-graduate education were significantly lower than those with high school/secondary school and junior college/undergraduate (P ＜ 0.05);the DP and PAL scores of bank staff with junior college/undergraduate were significantly lower than those with high school/secondary school(P ＜ 0.05);there was no significant difference in EE score of bank staff between junior college/undergraduate and high school/secondary school(P ＞ 0.05).The EE score of age ＞ 50 years old bank staff was significantly lower than that of age ＜ 30 years old,30-40 years old and 41-50 years old (P ＜0.05);there was no significant difference in EE score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).The DP score of 41-50 years old bank staff was significantly higher than that of age ＜ 30 years old (P ＜0.05);there was no significant difference in DP score among age ＜30 years old,30-40 years old and 41-50 years old bank staff (P ＞ 0.05).There was no significant difference in PAL score among all age groups (P ＞ 0.05).The three dimensions of job burnout had significant negative correlation with self-efficacy and job satisfaction (P ＜ 0.05).Conclusion Bank staff have a certain degree of job burnout.Age,sex,and education level maybe the influence factors of job burnout.Improvement of self-efficacy and job satisfaction may help to reduce the job burnout.

Objective To explore the relationship between aural pre-attentive processing and non-rapid eye movement(NREM) sleep interictal epileptiform discharge (IED) in children with benign childhood epilepsy with central-temporal spikes (BECTS),in order to provide objective electrophysiological basis for early assessment of cognitive function lesion of BECTS children and intervention.Methods Twenty-nine children diagnosed as BECTS in the Second Affiliated Hospital of Xinxiang Medical University from February 2012 to November 2015 were selected,including 17 males and 12 females,and they were 4-14 years old with average age of (9.17 ±2.42) years,and the course of disease was 0.5-4.0 years.Twenty healthy children who had hospital routine check-up were selected as healthy control group,containing 14 males and 6 females,and they were 5-13 years old with average age of (8.55 ±3.09) years.Mismatch negativity (MMN) test was carried out in both groups,and the MMN amplitudes and latencies were analyzed.The long-term video electroencephalogram (VEEG) monitoring was conducted in the BECTS group to analyze the discharge phases (waking,sleep),locations and the IED indexes.The intergroup MMN indexes and the correlation between MMN and VEEG in the BECTS group were compared.Results The VEEG showed that the sleep structure of BECTS children did not change obviously.All children's epileptiform discharges were located in the Rolandic area,including 11 cases on the left side,8 cases on the right side,and 10 cases on both sides.Epilepsy discharge time:17 patients showed epileptiform discharges in sleep stages only and 12 patients showed epileptiform discharge in both sleep and waking stages.Epileptiform discharges of the 12 patients increased more significantly in sleep stage than thatin waking stage [(40.24 ± 25.15) times/min vs.(1.92 ± 1.38) times/rmin],and the difference was statistically significant (t =5.270,P =0.000).The sample IED index in stage 1 and 2 of NREM was (40.73 ± 10.69) times/min,in which 2 cases had IED indexes ＜ 5 times/min,the IED indexes of 3 cases ＞ 80 times/min who reached electrical status epilepticus during sleep,and others were 17.2-64.6 times/min.Clinical seizures in sleep stages were monitored in only 4 cases,which showed an electro-clinical segregation phenomenon from large quantities of sleep IED.The MMN amplitude was lower in the BECTS group than that in the healthy control group [(6.06 ± 1.89) μV vs.(7.28 ±1.64) μV],and the difference was statistically significant (t =2.346,P =0.025).Latency of BECTS group was longer than that in the healthy control group [(191.37 ±40.13) ms vs.(179.35 ±39.80) ms],but the difference was not statistically significant(t =1.037,P =0.355).Correlation analysis showed that the MMN amplitude was negatively related to discharge phases (r =-0.407,P ＜ 0.05) and the IED indexes (r =-0.644,P ＜ 0.01),and latency was positively related to the IED indexes (r =0.386,P ＜ 0.05),while the other VEEG indexes were not correlated with MMN.Conclusions The BECTS children have aural pre-attentive processing disturbance,especially unconscious automatic processing ability impairment,which weakenattention switch action of automatic processing switching to focused attention processing and fail to filter irrelevant information effectively.Sleep IED is an important factor in impairing the formation and reinforcement of acoustic discrimination and memory trace,interfering the acquisition,processing,storage and matching of new information,which induces children pre-attentive processing disturbance.The MMN may discover the electrophysiological changes of children pre-attentive processing disturbance in early stage.

Objective To explore the reactive inhibition and electrophysiological changes under the GO/NOGO paradigm in patients with alcohol dependence (AD) in order to provide a theoretical basis for neuromechanism study of AD executive dysfunctions.Methods The GO/NOGO paradigm event related potentials (ERP) were tested in 51 AD patients and 29 healthy controls, this paradigm behavior and ERP-N1, N2 and P3 latency and amplitude were analyzed.ERPs and execution functions were followed at different time points of withdrawal(4, 9,13 weeks).Results The number of correct responses (29.18±3.03)lowered and error responses (5.16±3.77) heightened in AD patients, and differences had statistical significance compared with those in control group(32.35±2.58,3.19± 1.84, P＜0.05), and there was no group difference in response time.There was no statistical significance in group difference in N1 component under the GO/NOGO tasks and in P3 latency under GO.N2 ((3.48±2.21) μV, (4.49±3.00) pV) and P3 amplitude ((3.47±2.31) μV, (3.92±4.09) μV) decreased and N2 latency ((256.30±31.62) ms, (256.09±33.77)ms) prolonged in AD group under both GO/NOGO tasks and so did P3 latency ((355.33±25.96) ms) under the NOGO, and the differences had statistical significance.Group main effects in N2 and P3 component (P=0.000) and task main effects in N2 amplitude and P3 latency (P＜0.05) were significant,group and task interaction was significant only in P3 latency (P＜0.01).ERPs of AD patients had no notable changes at different time points of withdrawal, executive dysfunctions were the worst within the 1st week of withdrawal and gradually recovered to pre-withdrawal levels.Conclusion AD patients have lower reactive inhibition manifested mainly by weakened capacity to inhibit and adjust conflict monitor and pre-executive motor program, ERP and executive functions cannot be well improved during short-term withdrawal, and the GO/NOGO-ERP can completely reflect electrophysiological changes of reactive inhibition process of AD patients.

Objective To explore schizophrenic′s executive function and characteristics of event-related potential-P300 (ERP-P300) in a Go/Nogo paradigm in order to provide electrophysiological basis for schizophrenic′s executive function. Methods The Wisconsin card Sorting Tests (WCST) were conducted and ERP-P300s in a Go/Nogo paradigm (Go/NogoERP-P300) were determined in 58 schizophrenics and 30 healthy persons. Results The WCST score was poorer in research group than that in control group. ERP amplitudes lowered and latencies prolonged in Go-P3 and Nogo N2 and P3, and all differences had statistical significances (P < 0.05). But there were no differences in N1 of both tasks and Go-N2; Go-P3, Nogo-N2 and -P3 amplitude and latency were related to the WCST well (P < 0.05). Conclusion Schizophrenics have such lowered executive functions as attention and cognition conversion and reactive inhibition and could normally process task prophase merely , and Go/NogoERP-P300 may be one of electrophysiological methods reflecting schizophrenic′s executive function.
