Objective:To explore the effect of psychological training on self consistency and congruence of army men. Methods:532 army men were tested by Self Consistency and Congruence Scale(SCCS)、EPQ、simplified coping style questionnaire(SCSQ)and SCL-90. Results:There were significant difference in score of SCCS between army men group and norm.There were significant correlation between factor scores of SCCS and scores of EPQ,SCSQ and SCL-90. After psychological training,the study group had higher score in flexibility than that of norm. The study group had higher score in flexibility and positive coping style than control group,and lower scores in P and N of EPQ,total score,obsessive-compulsive,interpersonal sensitivity,anxiety,hostility,paranoid ideation and psychoticism of SCL-90 than control. Conclusion:Self consistency and congruence level of army men were associated with personality, coping style and mental health. The psychological training has effect on balancing personality,facilitating self consistency,improving coping style and the psychological status of army men.

Objective:To investigate the status of brain evoked potentials (BEP) and the relationship between BEP and psychiatric symptoms before and after treatment in patients with post-traumatic stress disorder (PTSD). Methods: P_(300), auditory evoked potential (AEP), visual evoked potential (VEP) of BEP, Symptom Checklist-90 (SCL-90) and Impact of Event Scale (IES) were used to evaluate 86 patients with PTSD (PTSD group) and 56 normal controls (control group), PTSD patients were followed up with the same markers after 3.5 months treatment.Results:Compared with the control group, PTSD patients showed delayed latency and increased amplitude of P_(300)-P_3, delayed AEP-N_2 latency, and delayed VEP-P_2 latency. Shortened latency and decreased amplitude of P_(300)-P_3, and shorted VEP-P_2 latency were found after treatment. The mostly items of BEP were significantly related to psychical symptoms before treatment, and the changes of BEP were significantly related to the alleviation of psychical symptoms after treatment.Conclusion:BEP might be state markers of PTSD. The clinical application of BEP in PTSD is emphasized.

Objective To investigate the variations of polysomnography of the patients with retardative depression and non-retardative depression. Methods Twenty-eight patients with depression without any medicine at least for 1 month and fifteen normal controls were assessed in this study. Based on the scores of retardation of Hamilton Depression Scale( HAMD), the patients were divided into the group of retardative depression and the group of non-retardative depression. Polysomnography was given to all the subjects. Results Compared with the normal controls, the depressive patients both in the retardative depression group and in the non-retardative depression group showed significant differences of lower total sleep time (TST), sleep efficiency (SE), SWS% , rapid eye movement ) sleep time ( RT), REM sleep latency (RL) ( all P ＜ 0. 05 ), and higher sleep latency (SL) , awakening time( AT), awakening number( AN ), the percentage of AT( A/TST% ), the percentage of 1 sleep( S1 % ), the percentage of RT( RT% ), REM activity ( RA), and REM intensity (RI). REM density (RD) in the retardative depression group was significantly higher than both the non-retardative depression group and the control group ( t =2.36, P＜ 0. 05; t = 2.75, P＜ 0. 05 ). Conclusion Abnormalities of PSG in depression are proved, and RD may be relative to retardation. The differences of PSG do not existed between different kinds of depression such as retardative depression and non-retardative depression.

Objective To investigate the acute mountain sickness of servicemen during4.14Yushu earhquake relief work,and analyze the related factors of the sickness at the initial phase of acute plateau exposure.Methods 162 servicemen were sampled randomly and clusteringly from Yushu relief force during.the inidal phase of acute plateau exposure.According to theDiagnosis and treatment principles of the acute mountain sickness,the prevalence of the acute mountain sickness was judged among the servicemen.The scales of general status invested score(GSIS),the self-rating symptom scale(SCL-90)and the life event scale(LES)were used to investigate the related factors of the acute mountain sickness.Results 65.4% of servicemen in earthquake relief work had acute mountain sickness,including mild 17.3%,moderate 31.5%and severe 16.7%.The occurrences of pant,palpitation,dizziness,lips cyanosis and headache,were higher than other symptoms,accounting for 83.6%,79.1%,73.1%,61.2%and 58.2%.The positive significant correlation was found among the symptoms score of acute mountain sickness and age,marriage,trauma history,negative events,and the most genes(somatization,obsession,depression,anxiety,hostility,fear,paranoia,appetite,sleep)and total score of SCL-90(r=0.188～0.619,P<0.01 or 0.05).There was negative significant correlation among the symptoms score and the personality and social support(r=-0.254,P<0.01;r=-0.285,P<0.01).Regression analysis showed that the somatization,personality,marriage,social support and age were more important than other factors.Conclusion Attention should be paid to the acute mountmn sickness in the relief force during the initial phase of acute plateau exposure,and the morbidity rate of acute mountain sickness were correlated with the somatization,personality,marriage,social support and age.

Objective To evaluate the effects of 6-week atypical antipsychotics treatment on serum brain-derived neurotrophic factor (BDNF)level,and the correlation between BDNF level and clinical efficiency in first-episode antipsychotic-na?ve schizophrenia.Methods We recruited 39 hospitalized patients with first-episode antipsychotic-na?ve schizophrenia that met with Diagnostic and Statistical Manual of Mental Disorders—4th Edition (DSM-IV).Both Positive and Negative Syndrome Scale (PANSS)and the level of serum BDNF were measured before and after 6 weeks’treatment with atypical antipsychotics.We also studied 30 healthy controls.Serum BDNF was assayed at baseline.Results Pre-treatment BDNF level was significantly lower in the schizophrenic patients than in the controls [(6.82±2.1 5 )μg/L vs .(1 1.6 ± 3.32 )μg/L,t = 7.239,P < 0.001 ].Although BDNF level increased with treatment (t =2.349,P =0.021)in the schizophrenics,post-treatment BDNF level was still lower than in the normal controls (t =4.634,P <0.001).After 6 weeks’treatment for schizophrenia,the total score of PANSS,the scores of positive and negative symptoms,and the score of general psychopathology scale were all decreased (t =6.1 64,P < 0.001;t = 4.520,P < 0.001;t = 4.132,P < 0.001;t = 5.142,P < 0.001 ).Pre-treatment BDNF levels were directly correlated not only with the rate of decreased PANSS total score (r =0.348, P <0.05),but also with the rate of decreased negative symptoms score (r = 0.35 1,P < 0.05 ).However,pre-treatment BDNF levels were not correlated with improved positive symptoms,general psychopathology (r =0.204, 0.186,P >0.05),or duration of illness (r = - 0.058,P > 0.05 ).Changes in BDNF levels with treatment were correlated with the duration of illness (r =-0.345,P <0.05),but not with psychiatric improvement (r =0.036-0.1 74,P >0.05).Conclusion BDNF level is significantly lower in patients with first-episode antipsychotic-na?ve schizophrenia than in normal controls.It could be improved by using antipsychotics.Higher pre-treatment BDNF level may predict better response to antipsychotics.

ObjectiveTo explore and analyze the effect of simulation-based learning combined with debriefing in neonatal resuscitation training.MethodsA total of 114 clinical medical staffs attended the neonatal resuscitation training course hold by Department of Neonatology, Quzhou Maternal and Child Health Hospital from November 2014 to May 2015, and were randomly assigned to observation (n=60) and control group (n=84) by coin tossing. Staffs in the observation group adopted to training skills with simulation-based learning combined with debriefing,while those in the control group were educated with traditional method. The examinations on theoretical knowledge were taken before and after the training. Operational exam and self-confident questionnaire for all staffs on each procedure taught in the course were taken at last. Scores of the exams and self-confident questionnaire were compared between the two groups witht-test and Mann-WhitneyU test.ResultsThe mean score of theoretical test rose up significantly after the training in both observation and control group (25.19±2.62 vs 20.17±3.71,t=7.725,P<0.01; 25.44±2.64 vs 18.90±4.27,t=11.170,P<0.01), but no difference was found in this score after the training between the two groups (t=0.492,P=0.624). The practical operation examination score in the observation group was higher than that in the control (34.05±1.34 vs 31.32±4.10,t=4.183,P<0.01). All questionnaires sent to the staffs were retrieved (100%), and the total values after the training in the observation group were higher than in the control (mean rank: 92.81 vs 57.99; rank sum:5 569 vs 4 872,Z=-4.96,P<0.01).ConclusionsSimulation-based learning combined with debriefing is a much more effective teaching methods for neonatal resuscitation training, which might quickly improve the resuscitation skills of clinical staffs.

Objective To compare the metabolic measures on prefrontal lobe and thalamus among schizophrenics with or without mental disorder family history by proton magnetic resonance spectroscopy (1 H-MRS),and to explore the relationship among metabolic measures,clinical symptom,and executive functioning.Methods Thirty-one schizophrenics with schizophrenia family history,21 schizophrenics with the other mental disorder family history,and 78 schizophrenics without mental disorder family history were examined at prefrontal lobe and thalamus by multi-voxel 1H-MRS.The N-acetylaspartate (NAA),Choline-congtaining compounds (Cho),and Creatine compounds (Cr) were measured and the ratios of NAA/Cr and Cho/Cr were determined.Meanwhile,Positive and Negative Syndrome Scale (PANSS) and Wisconsin Card Sorting Test (WCST) were also assessed in all schizophrenics.Results Both in schizophrenics with schizophrenia family history and with the other mental disorder family history,the NAA/Cr ratios showed lower than those in schizophrenics without mental disorder family history both on left prefrontal lobe and on fight thalamus ( P ＜ 0.05 ).Compared with schizophrenics without mental disorder family history,the score of negative symptoms and the perseverative errors demonstrated higher ( P＜ 0.05 or 0.01 ),the categories completed showed lower both in schizophrenics with schizophrenia family history and with the other mental disorder family history ( P＜0.05 ).The NAA/Cr ratios on left prefrontal lobe in all schizophrenics were significantly negatively related with the total score of PANSS and the responses errors (P ＜ 0.05 or P＜ 0.01 ),and positively related with the categories completed and the conceptual level responses ( P＜ 0.05 or P＜ 0.01 ).On left prefrontal lobe both in schizophrenics with schizophrenia family history and with the other mental disorder family history,the ratios of NAA/Cr were negatively related with the score of negative symptoms and the perseverative errors ( P ＜ 0.05 or 0.01 ).Conclusion The damages of neurons on prefrontal lobe and thalamus in schizophrenics with mental disorder family history may be more severe than those in schizophrenics without family history,and the damages on prefrontal lobe are related with negative symptoms and executive functioning.

ObjectiveTo explore the metabolite status on prefrontal lobe and thalamus by proton magnetic resonance spectroscopy (1H-MRS) and affecting factors in patients of schizophrenia.Methods 159 schizophrenics met with CCMD-3 and 45 normal controls were examined at prefrontal lobe and thalamus by multi-voxel 1H-MRS.The N-acetylaspartate ( NAA),Choline-congtaining compounds ( Cho),and Creatine compounds (Cr)were measured and the ratios of NAA/Cr,Cho/Cr were determined. Positive and Negative Syndrome Scale (PANSS),Social Disability Screening Schedule (SDSS),and Wisconsin Card Sorting Test (WCST) were also assessed.ResultsOn left prefrontal lobe of patients,the NAA/Cr ratio demonstrated lower than that in normal controls (1.42 ±0.34 vs.1.64 ±0.39,t =3.70,P＜0.01 ).The same phenomenon were appeared on left thalamus (1.46±0.35 vs.1.66±0.38,t=3.32,P＜0.01) and on right thalamus (1.49±0.34 vs.1.62±0.37,t=2.04,P ＜ 0.05 ).Contributing to the NAA/Cr ratio,main influencing factors on left prefrontal lobe were age of onset,duration of illness,score of negative symptoms,antipsychotic treatment,total score of PANSS,Categories completed of WCST,total score of SDSS,year of education.Main influencing factors on left thalamus were age of onset,duration of illness,antipsychotic treatment.Main influencing factors on right thalamus were duration of illness,age of onset,score of negative symptoms,antipsychotic treatment,and family history.ConclusionsAbnormalities in neuronal function and/or integrity presented on prefrontal lobe and thalamus in schizophrenics are related to many respects,especially age of onset,duration of illness and antipsychotic treatment.
