Objective To evaluate the psychological trauma incurred by the hospitalization survivor of Zhouqu district after the Zhouqu debris flow so as to provide relevant information for psychological and medical interventions. Methods The psychological state of 67 hospitalized survivors of the disaster and other 47 inpatients with similar complaints but not coming from the disaster area was investigated through a mental health self-assessment questionnaire, self-rating anxiety scale (SAS), self-rating depression scale (SDS) and PTSD-SS scale. Results The post-disaster survivors had different levels of psychological problems and post-traumatic stress disorder, and there were significant differences compared to the control group (Plt;0.01, Plt;0.01). The SDS score and the SAS score of the survivor were 48.44+15.648 and 52.92+11.672, respectively, which were all much higher than those of the control group (Plt;0.01, Plt;0.05). Conclusion The debris flow disaster bring serious psychological trauma to the victims. It is necessary to pertinently carry out post-disaster psychological relief including psychological intervention and regulation for the hospitalized survivors, so as to alleviate and reduce their psychological suffering.
目的 探讨“5.12”地震后北川羌族人群中类风湿关节炎（RA）患者外周血 T细胞亚群的表达情况并分析创伤后应激障碍（PTSD）对RA患者细胞免疫之间的影响。 方法 2009年3月－2010年3月，对98例北川羌族RA患者、112例健康对照，以及同期绵阳郊区84例RA患者、120例健康对照进行分析。用流式细胞仪分别检测CD3+、CD3+CD4+、CD3+ CD8+ T淋巴细胞数及CD4/+CD8+比值， RA疾病活动性采用DAS28测定，应用美国精神障碍诊断与统计手册第4版（DSM-Ⅳ）诊断标准调查RA人群中的PTSD患者，应用PTSD检查表平时版（PCL-C）检查对PTSD患者进行分析。 结果 北川羌族与绵阳郊区RA活动组患者（分别为58例、39例）与健康对照组比较，CD8+ T淋巴细胞数降低，CD+4/CD8+比值增高，差异有统计学意义（P＜0.05）；北川羌族RA活动组与绵阳郊区RA活动组比较，CD3+ T淋巴细胞数降低，差异有统计学意义（P＜0.05）。北川RA患者中PTSD者（38例）与非PTSD者（60例）比较，PTSD组CD3+ T淋巴细胞数和CD4+/CD+8比值均明显低于PTSD组，差异有统计学意义（P＜0.05）；PCL-C对北川RA患者中PTSD的测定发现，PCL高分组CD3+ T淋巴细胞数显著低于PCL低分组（P＜0.05）。 结论 “5.12”地震后一部分RA患者出现T细胞免疫功能异常，且免疫功能异常与PTSD有关，对合并有PTSD的进行RA患者早期心理干预及药物治疗，改善患者生存质量。
Objective To investigate the quality of life (QOL) of Beichuan cadres 1 year after Wenchuan earthquake, so as to provide references for promoting psychological intervention and improving QOL. Methods With the adoption of WHOQOL-BREF, questionnaire survey on basic conditions of cadre victims, and PCL-C scale, cross-section survey was conducted for 2 055 cadres of Beichuan public institutions in aspects of their QOL, social demographic characteristics and psychological trauma. Results a) Compared with domestic norm, although the Beichuan cadres had higher score in social relation domain (14.31 ± 2.59, Plt;0.01), their QOL scores in each dimensions (physical domain score: 14.16 ± 2.43; psychological domain score: 13.79 ± 2.59, environmental domain score: 11.20 ± 2.74) were lower with significant difference (Plt;0.01); b) The group with population under the age of 30 scored higher than other age groups in the psychological and environmental domains; men scored higher than women in the psychological domain; the widowed group scored lower than other groups in all domains; the Han nationality group scored higher than the Qiang nationality group in all domains; the primary education group scored lower than other groups in the social relation domain; the group with relatives, houses and physical loss or damage scored lower than the non-loss group in all domains; and the higher the score in PCL-C, the lower the scores in all domains (all Plt;0.05). Conclusion Beichuan cadres are severely affected in their physical, psychological and environmental domains even one year after Wenchuan earthquake, especially the female, the Qiang nationality, the old, the lost, and the psychological injured cadres are more badly affected with worse QOL, so those population should be concerned in particular with sustainable psychological service and other measures. The finding of social relation domain score being higher than general population suggests that it is important to promote the satisfaction with social relation through the timely effective support from both government and civil society, and the resettlement of sample housing area as well.
目的 利用局部一致性（ReHo）方法探测创伤后应激障碍（PTSD）患者在静息状态下是否存在着大脑功能异常。 方法 2010年5月－7月对18例未经治疗的地震PTSD患者和19例同样经历地震但未患PTSD的对照者进行了静息态功能磁共振成像（Rs-fMRI） 扫描。应用ReHo方法处理Rs-fMRI数据，得出PTSD患者的异常脑区，并将患者存在组间差异的脑区ReHo值与临床用PTSD诊断量表（CAPS）、汉密尔顿抑郁量表（HAMD）和汉密尔顿焦虑量表（HAMA）分别进行相关分析。 结果 ① PTSD组ReHo显著增加的脑区包括右侧颞下回、楔前叶、顶下叶、中扣带回，左侧枕中回以及左/右侧后扣带回；ReHo显著降低的脑区包括左侧海马和左/右侧腹侧前扣带回。② 异常脑区中后扣带回和右侧中扣带回ReHo与HAMD呈负相关（中扣带回r=?0.575，P=0.012；右侧后扣带回：r=?0.507，P=0.032），其余脑区ReHo与临床指标无明显相关性（P＞0.05），左侧海马与CAPS的相关性相对其他脑区较大（r=?0.430，P=0.075）。 结论 PTSD患者在静息状态下即存在着局部脑功能活动的降低和增加，ReHo方法可能有助于研究PTSD患者静息状态脑活动。
Post-traumatic stress disorder (PTSD) presents with complex and diverse clinical manifestations, making accurate and objective diagnosis challenging when relying solely on clinical assessments. Therefore, there is an urgent need to develop reliable and objective auxiliary diagnostic models to provide effective diagnosis for PTSD patients. Currently, the application of graph neural networks for representing PTSD is limited by the expressiveness of existing models, which does not yield optimal classification results. To address this, we proposed a multi-graph multi-kernel graph convolutional network (MK-GCN) model for classifying PTSD data. First, we constructed functional connectivity matrices at different scales for the same subjects using different atlases, followed by employing the k-nearest neighbors algorithm to build the graphs. Second, we introduced the MK-GCN methodology to enhance the feature extraction capability of brain structures at different scales for the same subjects. Finally, we classified the extracted features from multiple scales and utilized graph class activation mapping to identify the top 10 brain regions contributing to classification. Experimental results on seismic-induced PTSD data demonstrated that our model achieved an accuracy of 84.75%, a specificity of 84.02%, and an AUC of 85% in the classification task distinguishing between PTSD patients and non-affected subjects. The findings provide robust evidence for the auxiliary diagnosis of PTSD following earthquakes and hold promise for reliably identifying specific brain regions in other PTSD diagnostic contexts, offering valuable references for clinicians.
ObjectiveTo understand the relationship between post-traumatic stress disorder (PSTD) and perceived stress in suspected coronavirus disease 2019 (COVID-19) patients quarantined in hospital.MethodsA cross-sectional study of 93 suspected COVID-19 patients in one of grade-A tertiary hospital in Southwest China was carried out to evaluate the incidence of perceived stress and post-traumatic stress symptoms among these patients using the standardized Perceived Stress Scale-10 (PSS-10) and PTSD Checklist-5 (PCL-5), respectively. Pearson correlation was used to analyze the correlation between PCL-5 and PSS-10 scores.ResultsTotal PSS-10 and PCL-5 scores were 16.7±5.2 and 17.0±11.6 in 93 suspected COVID-19 patients, respectively. Positive correlations between PSS-10 and PCL-5 scores were detected (Pearson’s r=0.722, P=0.000).ConclusionsThe occurrence and development of PSTD of suspected COVID-19 patients have the relationship with the early perceived pressure. It suggests that medical staff should identify and intervene the perceived pressure level of patients who are under quarantine as suspected COVID-19 early and effectively, so as to reduce the occurrence of PTSD.
In the current study, we aim to investigate whether post-traumatic stress disorder (PTSD) is associated with structural alterations in specific subfields of hippocampus comparing with trauma-exposed control (TC) in a relatively large sample. We included 67 PTSD patients who were diagnosed under Diagnostic and Statistical Manual of Mental Disorders (4th Edition) (DSM-Ⅳ) criteria and 78 age- and sex-matched non-PTSD adult survivors who experienced similar stressors. High resolution T1 weighted images were obtained via a GE 3.0 T scanner. The structural data was automatically segmented using FreeSurfer software, and volume of whole hippocampus and subfield including CA1, CA2-3, CA4-DG, fimbria, presubiculum, subiculum and fissure were extracted. Volume differences between the two groups were statistically compared with age, years of education, duration from the events and intracranial volume (ICV) as covariates. Hemisphere, sex and diagnosis were entered as fixed factors. Relationship between morphometric measurements with Clinician-Administered PTSD Scale (CAPS) score and illness duration were performed using Pearson’s correlation with SPSS. Comparing to TC, PTSD patients showed no statistically significant alteration in volumes of the whole hippocampus and all the subfields (P > 0.05). In male patients, there were significant correlations between CAPS score and volume of right CA2-3 ( R2 = 0.197, P = 0.034), right subiculum (R2 = 0.245, P = 0.016), and duration statistically correlated with right fissure (R2 = 0.247, P = 0.016). In female patients, CAPS scores significant correlated with volume of left presubiculum (R2 = 0.095, P = 0.042), left subiculum (R2 = 0.090, P = 0.048), and left CA4-DG (R2 = 0.099, P = 0.037). The main findings of the current study suggest that stress event causes non-selective damage to hippocampus in both PTSD patients and TC, and gender-specific lateralization may underlie PTSD pathology.

Post-traumatic stress disorder (PTSD) is a mental disorder causing great distress to individuals, families and even society, and there is not yet effective way of unified prevention and treatment up till now. Lots of neuroimaging techniques, however, such as the magnetic resonance imaging, are widely used to the study of the pathogenesis of PTSD with the development of medical imaging. Functional magnetic resonance imaging (fMRI) can be applied to detect the abnormalities not only of the brain morphology but also of the function of various cerebral areas and neural circuit, and plays an important role in studying the pathogenesis of psychiatric diseases. In this paper, we mainly review the task-related and resting-state functional magnetic resonance imaging studies of the PTSD, and finally suggest possible directions for future research.
