目的:探讨孤独症儿童父母照顾负担的潜在类别,并分析影响不同潜在类别的因素。方法:采取便利抽样法,选取2021年6—8月在宁波、温州两市5所孤独症儿童康复机构训练的孤独症儿童父母作为调查对象,采用一般资料调查表、家庭复原力评估量表和Zarit照顾者负担量表进行调查。对孤独症儿童父母的照顾负担进行潜在类别分析,并通过单因素分析及有序多分类Logistic回归分析探讨照顾负担潜在类别的影响因素。结果:共回收问卷280份,其中有效问卷260份,有效问卷回收率为92.86%。经潜在类别分析,孤独症儿童父母的照顾负担分为3个潜在类别,分别为低负担组(35.8%)、中负担组(41.5%)、高负担组(22.7%)。有序多分类Logistic回归分析结果表明,家长年龄越大(OR=1.050,95%CI=0.009~0.089,P=0.016),康复训练时间3~6 h(OR=2.098,95%CI=0.188~1.294,P=0.009)及>6 h(OR=2.667,95%CI=0.211~1.752,P=0.013),康复费用占比>60%(OR=2.886,95%CI=0.158~1.963,P=0.021)的孤独症儿童父母归属于高负担组的概率越大;而家庭复原力总分越高的孤独症儿童父母归属于低负担组的概率越大(OR=0.954,95%CI=-0.062~-0.031,P<0.001)。结论:孤独症儿童父母的照顾负担存在异质性,可分为3个潜在类别。家长年龄越大、康复训练时间越长、康复费用占比越高、家庭复原力越低的父母照顾负担越重。临床医护人员应关注高龄及康复训练投入大的父母,并帮助家庭建立面对逆境的积极信念及有效应对策略以降低照顾负担。

ZNF804A Variation May Affect Hippocampal-Prefrontal Resting-State Functional Connectivity in Schizophrenic and Healthy Individuals

Neuroscience Bulletin 2018年第3期34卷 507-516页

作者： Yuyanan Zhang Hao Yan Jinmin Liao Hao Yu sisi jiang Qi Liu Dai Zhang Weihua Yue Institute of Mental Health Peking University Sixth HospitalBeijing 100191 China Key Laboratory of Mental Health Ministry of Health and National Clinical Research Center for Mental Disorders(Peking University) Beijing 100191 China Department of Psychiatry Jining Medical UniversityJining 272067 China Peking-Tsinglaua Joint Center for Life Sciences and PKUIDG/McGovern Institute for Brain Research Peking University Beijing 100871 China

The ZNF804 A variant rs1344706 has consistently been associated with schizophrenia and plays a role in hippocampal-prefrontal functional connectivity during working memory. Whether the effect exists in the resting state and in patients with schizophrenia remains unclear. In this study, we investigated the ZNF804 A polymorphism at rs1344706 in 92 schizophrenic patients and 99 healthy controls of Han Chinese descent, and used resting-state functional magnetic resonance imaging to explore the functional connectivity in the participants. We found a significant main effect of genotype on the resting-state functional connectivity（RSFC） between the hippocampus and the dorsolateral prefrontal cortex（DLPFC） in both schizophrenic patients and healthy controls. The homozygous ZNF804 A rs1344706 genotype（AA） conferred a high risk of schizophrenia, and also exhibited significantly decreased resting functional coupling between the left hippocampus and right DLPFC（F（2,165） = 13.43,P ／ 0.001）. The RSFC strength was also correlated with cognitive performance and the severity of psychosis in schizophrenia. The current findings identified the neural impact of the ZNF804 A rs1344706 on hippocampalprefrontal RSFC associated with schizophrenia.

Progressive Grey Matter Volume Changes in Patients with Schizophrenia over 6 Weeks of Antipsychotic Treatment and Their Relationship to Clinical Improvement

引用

Neuroscience Bulletin 2018年第5期34卷 816-826页

作者： Xiao Zhang Yuyanan Zhang Jinmin Liao sisi jiang Jun Yan Weihua Yue Dai Zhang Hao Yan Peking University Sixth Hospital/Institute of Mental Health Beijing 100191 China Key Laboratory of Mental Health Ministry of Health (Peking University) and National Clinical Research Center for Mental Disorders (Peking University Sixth Hospital) Beijing 100191 China Peking-Tsinghua Joint Center for Life Sciences and PKU IDG/McGovern Institute for Brain Research Peking University Beijing 100871 China

Cross-sectional and longitudinal studies have identified widespread and progressive grey matter volume （GMV） reductions in schizophrenia, especially in the frontal lobe. In this study, we found a progressive GMV decrease in the rostral medial frontal cortex （rMFC, including the anterior cingulate cortex） in the patient group during a 6-week follow-up of 40 patients with schizophrenia and 31 healthy controls well-matched for age, gender, and education. The higher baseline GMV in the rMFC predicted better improvement in the positive score on the Positive and Negative Syndrome Scale （PANSS）, and this might be related to the improved reality-monitoring. Besides, a higher baseline GMV in the posterior rMFC predicted better remission of general symptoms, and a lesser GMV reduction in this region was correlated with better remission of negative symptoms, probably associated with ameliorated self-referential pro- cessing and social cognition. Besides, a shorter disease course and higher educational level contributed to better improvement in the general psychopathological PANSS score, and a family history was negatively associated with improvement of the negative and total PANSS scores. These phenomena might be important for understanding the neuropathological mechanisms underlying the symp- toms of schizophrenia and for making clinical decisions.

目的探讨慢性病患儿心理行为适应特征的潜在类别,比较不同类别慢性病患儿在人口学特征及家庭复原力上的差异,分析潜在类别的影响因素。方法采用便利抽样法,选取2019年6月—9月在上海市与浙江省4所三级甲等医院门诊就诊或住院的307名慢性病患儿家长作为调查对象,采用一般人口学资料问卷、长处与困难问卷(家长版)和家庭复原力评估量表进行调查。对慢性病患儿的心理行为适应特征进行潜在类别分析,并通过单因素分析和Logistic回归识别其潜在类别的影响因素。结果慢性病患儿的心理行为适应特征分为3个潜在类别,分别为心理行为健康组(48.9%)、多动-低亲社会行为组(48.2%)、高心理行为问题组(2.9%)。将高心理行为问题组、多动-低亲社会行为组合并为心理行为问题组,进行Logistics回归分析。结果显示,年龄、疾病类型和家庭复原力是患儿心理行为适应特征潜在类别的影响因素。结论慢性病患儿的心理行为适应特征存在异质性,可分为3个潜在类别。年龄较小、患有神经系统疾病、低家庭复原力的患儿出现心理行为问题的风险更高。
