Objective: To analyze the influential factors of job burnout among psychiatrists.Methods: Psychiatirsts were evaluated by questionnaires.Results: In general,the job burnout of psychiatrists was very serious.There were significant differences in gender in burnout individual level;the person of 31-35 age was prone to job burnout,and the middle-aged staffs’ job burnout was comparatively in high level;There was significantly correlated show between psychiatrists job burnout level and social support.Besides,there was significantly correlated show between psychiatrists job burnout level and coping way.Conclusion: Psychiatrists Burnout is a high-risk population.To better enhance the stability of their profession,we need concern psychiatrists’mental health from the integrated perspective,and improve their level of social support constantly,and prevent occupational burnout from the perspective of medical education early.

Objective To investigate influence of mirtazapine on polysomnograpy (PSG) of depression dysphylaxia patient and treatment effect.Methods 22 dysphylaxia patients and 22 healthy contrast persons were detected by PSG.The group of dysphylaxia patients were re-detected PSG 6 weeks later after treatment by Mirtazapine.In order to evaluate the patient' symptoms of depression and early awakening,the scale of HAMD was utilized at the time before and after 2 weeks,6 weeks treatment by mirtazapine.To compare changes of PSG index,HAMD scores and dysphylaxia scores before and after treatment.Results Compared with healthy controls,there existed much deviation with dysphylaxia patients on PSG index.6 weeks after mirtazapine treatment,the PSG showed the sleeping latency had shortened to ( 16.9 ± 6.6) min,sleep efficiency had improved ( 85.4 ± 6.7 ) ％,awake time had shortened (27.7 ± 10.4)min,sleep maintenance rate had risen (87.9 ±5.3)％,decrease (9.7±4.1 )％ of the S1 sleeping stage percentage,S2 had increased ( 148.0 ±30.7)％,REM density had decreased (56.1 ±3.8)％.the difference was significant (P＜0.05).The scores of HAMD and early awakening after treatment were significantly lower than before treatment,the difference was significant (P＜0.01 ).Correlation analysis showed there was no significant correlation between the HAMD,dysphylaxia reduced rate and changes of PSG all indicators(P ＞ 0.05 ).Conclusion It may be one of the biological markers for dysphylaxi in shortened of REM sleep latency,prolonged of REM sleep time and increased of REM activity and density.There is no correlation between post-treatment changes of PSG.

Objective To study the effect of PBL and role play in the teaching of psychiatric nursing . Methods 88 nursing majors were divided into 9 groups and students found problems of psychiatric patients by role playing . Teacher analyzed problems , conducted self-reflect and revived teaching scheme and guided students to analyze problems and self-study.Meanwhile, effect of this teaching reform and traditional teaching methods was compared by check analysis .Results Students ’ test score was ( 87.24 ±5.23 ) in the experimental group and (70.12 ±6.03)in the control group after classes, with statistically significant difference (t=4.27,P<0.05).Students’ satisfaction of teaching method was 92.71% in the experimental group and 83.11% in the control group, with statistically significant difference (χ2 =4.41,P <0.05).Students’ evaluation of teaching was (90.27 ±0.68)in the experimental group and (85.15 ±0.47)in the control group, with statistically significant difference (t =9.18,P<0.05).Conclusions Teaching practice of psychiatric nursing combined PBL and role playing can effectively improve studnents ’ test scores and teaching effect , which has good implementation perspective in the future .

Objective To explore the changes of whole brain white matter ( WM) structural net-work topological property in patients with schizophrenia (SP) and the associations between WM networks to-pological efficiency and clinical variables in patients. Methods Deterministic tractography was used to con-struct the WM networks of 59 patients with SP ( patients group) and 41 age-, handedness-, and gender-matched healthy controls (HCs),and graph theoretical methods were applied to investigate abnormalities in the global and nodal properties of the WM network in these patients. Partial correlation analysis was used to analyze the relationship between global and nodal properties of the WM network and clinical variables in pa-tients with SP. Results Both the patients with SP and HCs showed small-world organization of the WM net-works. However,compared with HCs,the patients with SP exhibited significant abnormal global topology,in-cluding increased shortest path length ( t=7. 95, P=0. 0001) and decreased global efficiency ( 30. 83 ± 16. 08,8. 25±6. 13,t=-9. 81,P=0. 002),clustering coefficiency (0. 03±0. 01,0. 02±0. 01,t=-4. 48,P=0. 0003),the average clustering coefficiency (t=-8. 28,P=0. 002),the small-worldness (3. 92±0. 79,2. 79 ±0. 56,t=-7. 82,P=0. 001) of their WM structural networks(all P<0. 005,FDR corrected). Further,the patients with SP showed a reduction in nodal efficiency predominately in the cingulate gyrus ( t=-4. 11, P=0. 000),superior occipital gyrus ( t=-6. 05, P=0. 002), superior temporal gyrus ( t=-10. 46, P=0. 001),middle temporal gyrus (t=-10. 38,P=0. 000),thalamus (t=-6. 10,P=0. 000) and putamen ( t=-8. 38,P=0. 000) (P<0. 005,FDR corrected). Partial correlation results showed that there was no signifi-cant correlation between global topological properties,node efficiency and clinical symptoms in patients group (Eglob:r=-0. 14,P=0. 279;Eloc:r=-0. 06,P=0. 628;Lp:r=0. 28,P=0. 031;Cp:r=0. 27,P=0. 043;λ:r=-0. 18,P=0. 166;γ:r=-0. 29,P=0. 026;σ:r=0. 26,P=0. 048;nEglob:r=0. 36,P=0. 005;nEloc:r=0. 02,P=0. 901). Conclusions The patients with SP exhibit the abnormal of whole brain WM structural network topological property and the node efficiencies of cortico-striato-thalamo circuitry are significantly re-duced.

BackgroundCurrently， the problem of depressed mood in college students is becoming more prominent. The experience of childhood maltreatment is a significant contributor to depression among college students. Although the association between the two has been confirmed， the specific psychosocial mechanisms underlying how childhood maltreatment affects college students' mental health remain insufficiently evidenced. ObjectiveTo explore the mediating role of emotion regulation difficulties in the relationship between childhood maltreatment and depression among college students， and to investigate the moderated effects of psychological resilience and family socioeconomic status， aiming to provide references for improving depressive symptoms in college students. MethodsOn 14 March 2024， a cluster sampling method was employed to recruit 751 college students from a university in Heilongjiang Province. Participants were assessed with Childhood Trauma Questionnaire （CTQ）， Difficulties in Emotion Regulation Scale （DERS）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， 10-item Connor-Davidson Resilience Scale （CD-RISC-10） and Family Socioeconomic Status Questionnaire. Pearson correlation analysis was adopted to examine the correlation between the scores of scales. Model 4 and model 7 in Process 4.2 were used to test the mediating effects of emotional regulation difficulties and the moderated effects of psychological resilience and family socioeconomic status. Results① A total of 712 （94.81%） valid questionnaires were collected. ② College students' CTQ score was positively correlated with DERS score and PHQ-9 score （r=0.296， 0.507， P<0.01）， and negatively correlated with CD-RISC-10 score and Family Socioeconomic Status Questionnaire score （r=-0.148， -0.229， P<0.01）. ③ The indirect effect value of difficulties in emotion regulation on the relationship between childhood maltreatment and depression was 0.091 （95% CI： 0.018~0.046）， accounting for 17.95% of the total effect. ④ The first half of the mediation model "childhood maltreatment → difficulties in emotion regulation → depression" （childhood maltreatment → difficulties in emotion regulation） was moderated by psychological resilience （β=-0.030， t=-6.147， 95% CI： -0.040~-0.020） and family socioeconomic status （β=-0.051， t=-3.929， 95% CI： -0.077~-0.026）. ConclusionChildhood maltreatment exerts both a direct effect on college students' depression and an indirect effect through emotion regulation difficulties. The childhood maltreatment → emotion regulation difficulties pathway in this mediation model is moderated by psychological resilience and family socioeconomic status. ［Funded by Qiqihar Medical University Graduate Student Innovation Fund Project （number， QYYCX2023-48）； Special Research Fund Project for Young Doctors of Qiqihar Academy of Medical Sciences （number， QMSI2021B-08）］
