ObjectiveTo clarify the relationship between childhood maltreatment and insomnia in middle school students， and to explore the mediating role of post-traumatic stress disorder （PTSD） symptoms and the moderating role of mental resilience involvement.MethodsFrom April to May 2021， a total of 3 412 students in 3 middle schools in a city in western China were selected using convenient sampling method， and all students were assessed by Childhood Trauma Questionnaire （CTQ）， Post Traumatic Stress Disorder Scale （PCL）， Insomnia Severity Index （ISI） and mental resilience scale. The moderated mediating effect analysis was conducted using Process v3.4.ResultsAmong the middle school students， CTQ scores were positively correlated with PCL and ISI scores （r=0.540， 0.320， P<0.05）， and the scores of CTQ， PCL and ISI were negatively correlated with the score of mental resilience scale （r=-0.049， -0.193， -0.132， P<0.05）. PTSD symptoms exhibited a partial mediating effect on the relationship between general childhood maltreatment and insomnia （β=0.161， P<0.05）， accounting for 80.5% of the total effect.ConclusionAmong the middle school students， the relationship between childhood maltreatment and insomnia is partially mediated via PTSD symptoms， and mental resilience exerts a moderating role between childhood maltreatment and PTSD symptoms.

ObjectiveTo study the anxiety and depression status of the third-year junior high school students in Nanning city， and to discuss their relationships with test anxiety， so as to provide references for targeted psychological intervention for students.MethodsFrom May to June， 2021， a simple random sampling method was adopted to randomly enroll three classes of third-grade students from one junior high school in each district and county of Nanning city. The selected students were assessed using Test Anxiety Scale （TAS）， Self-rating Anxiety Scale （SAS） and Self-rating Depression Scale （SDS）. Thereafter， Pearson correlation analysis was conducted to explore the correlation among each scale score.ResultsA total of 2 080 students participated in the survey， and 1 826 （87.79%） valid questionnaires were collected. Among them， 999 students （54.71%） felt uncomfortable due to the test. Anxiety and depression were detected in 577 （31.60%） and 830 （45.45%） students， respectively. TAS score of female students was higher than that of male students ［（16.75±6.78） vs. （15.08±6.97）， t=-5.136， P<0.01］， SAS score of female students was higher than that of male students ［（46.05±10.43） vs. （44.16±10.87）， t=-3.769， P<0.01］， and SDS score of female students was higher than that of male students ［（52.34±12.44） vs. （49.98±12.17）， t=-4.039， P<0.01］. Correlation analysis showed that SAS and SDS scores were positively correlated with TAS score （r=0.574， 0.531， P<0.01）， and the correlation still existed after further controlling for age and gender （r=0.570， 0.526， P<0.01）.ConclusionThe third-year junior high school students in Nanning city suffer a high prevalence rate of anxiety and depression， and the two psychological states have positive relations with TAS. Furthermore， both anxiety and depression are more severe in female students than in male students.

Objective:To explore the mediating role of insomnia between childhood trauma and suicide risk in middle school students.Methods:Childhood trauma questionnaire(CTQ), insomnia severity index(ISI) and suicidal behaviors questionnaire-revised(SBQ-R) were used to investigate 3 442 middle school students.According to the total score of the SBQ-R, those who scored less than or equal to 6 were divided into low suicide risk group, and those who scored more than or equal to 7 were divided into high suicide risk group.In this study, there were 2 168 students in the low suicide risk group and 1 274 students in the high suicide risk group.SPSSAU 21.0 online statistical software was used for common method deviation test, descriptive statistics, variance analysis and correlation analysis, and structural equation model was constructed, and Bootstrap method was used for mediation effect test.Results:(1) There were statistically significant differences between the high suicide risk group and the low suicide risk group in terms of grade and gender( χ2=11.144, 83.737, both P<0.05), and there were statistically significant differences in the types of childhood trauma and the severity of insomnia( χ2=292.211, 333.998, both P<0.05). (2) The total score of childhood trauma in the high suicide risk group (43.92±10.50) was higher than that in the low suicide risk group (37.74±6.93) ( F=351.78, P<0.01), and the score of insomnia in the high suicide risk group (10.66±5.54) was higher than that in the low suicide risk group (7.04±4.76) ( F=379.25, P<0.01). (3)The total score of childhood trauma was positively correlated with the score of suicide risk ( r=0.415, P<0.01), and the total score of childhood trauma was positively correlated with the score of insomnia ( r=0.306, P<0.01), and the score of insomnia was significantly positively correlated with the score of suicide risk ( r=0.399, P<0.01). After controlling for demographic data, anxiety and depression, the correlation was still significant ( P<0.01). (4) Path analysis and mediation test showed that childhood trauma had a positive effect on insomnia ( β=0.30, P<0.01), insomnia had a positive effect on suicide risk ( β=0.29, P<0.01), and childhood trauma had a positive effect on suicide risk ( β=0.33, P<0.01). The mediating effect of insomnia accounted for 21.21% of the total effect.After controlling for demographic data, anxiety and depression, the mediating effect accounted for 10.66% of the total effect. Conclusion:Childhood trauma and insomnia have a significant impact on the suicide risk among middle school students.Insomnia plays a partial mediating role between childhood trauma and middle school students' suicide risk.Timely management of the sleep disturbances of traumatized individuals can reduce the suicide risk among middle school students.

抑郁症作为一种高发精神疾病,其评估主要依赖患者的临床症状,为提升对这种高发精神疾病的临床干预效果,许多研究者开始寻找可测量的生物标志物.事件相关电位(ERP)作为一种电生理学指标,非常适合对抑郁症患者进行个体化神经认知评估,其中失匹配负波(MMN)和P300是目前研究较多的ERP成分.MMN是一种负向的潜伏期为150～250 ms的ERP成分,能反映前注意加工过程,其神经发生源位于初级听觉皮层和前额叶皮层.MMN振幅下降、潜伏期延长有助于抑郁症的诊断,且与抑郁程度具有相关性,能够反映抗抑郁疗效,可能是抑郁症和双相情感障碍鉴别诊断的生物标志物.P300是由刺激诱发的潜伏期约300 ms的晚期正向波,P300振幅和潜伏期提供了记忆、注意和心理处理速度等认知过程信息.P300振幅的降低反映了抑郁症患者广泛的认知障碍,可提高抑郁症的诊断正确率,还可在一定程度上反应抗抑郁疗效,可能是区分重度抑郁症和双相情感障碍的潜在生物标志物.

Purpose: Post-stroke depression (PSD) is the most common psychiatric sequelae of stroke. Numerous studies revealed that event -related potentials (ERP) can reflect depression severity to a certain extent, while there is almost no research on depression after hemorrhagic stroke. Therefore, we employed a prospective cross-sectional study to explore the relationship between ERP and depression after hemorrhagic stroke.Methods: A total of 74 patients with intracranial hemorrhage were included in this study. Neurological deficits were evaluated using the National Institutes of Health Stroke Scale (NIHSS) on admission. Depression severity and cognitive impairment were measured using the 17-item Hamilton Depression Scale (HAMD-17) and the Chinese version of the Montreal Cognitive Assessment (MoCA) after two weeks of treatment. All patients were conducted auditory Oddball paradigm for event-related potential mismatch negativity (MMN) and P300.Results: In total, 36 patients were diagnosed with PSD at the two weeks of treatment, for a percentage of 48.6%. Depression severity of ICH patients correlated positively with both the latency of MMN (r = 0.376, P = 0.001) and P300 (r = 0.325, P = 0.005), and correlated negatively with both the amplitude of MMN (r=-0.385, P = 0.001) and P300 (r=-0.311, P = 0.007). Depression severity was negatively correlated with cognitive function after hemorrhagic stroke (r=-0.347, P = 0.002).Conclusion: The latency and amplitude of MMN and P300 can well reflect the degree of depression after hemorrhagic stroke, which may help in the early diagnosis and effective treatment of PSD.
