PURPOSE:Brain development is accompanied by gradual refinement of large-scale functional communication. Recent work indicates that functional connectivity can be characterized by both linear and nonlinear dependencies, raising the possibility that maturation involves a shift toward more linearly organized coupling. Whether this developmental trajectory differs in autism spectrum disorder (ASD) is not yet clear. METHODS:We analyzed resting-state fMRI data from the ABIDE cohort, including 188 males with ASD and 216 age-matched typically developing (TD) males. The ASD group had a mean age of 15.66 ± 66.13 years (range = 6-35), and the TD group had a mean age of 15.71 ± 5.97 years (range = 7-35). After standard preprocessing, we estimated linear and nonlinear connectivity for each participant and derived an index reflecting the extent to which nonlinear interactions were accounted for by linear coupling. This index was examined at the whole-brain scale and within canonical large-scale networks defined by the Yeo 7-network framework. Group differences and age-related effects were assessed, with multiple-comparison correction applied to network-level analyses. RESULTS:At the whole-brain level, ASD participants showed significantly lower R² values than TD participants. At the network level, significant between-group differences were observed in the visual, somatomotor, dorsal attention, ventral attention, and default mode networks. Across the typically developing group, the index increased significantly with age, suggesting a gradual strengthening of linear structure in functional interactions during maturation. In contrast, the ASD group showed only a weak relationship with age. At the network level, age-related associations were more widespread in the TD group than in the ASD group. In TD, significant positive age associations were observed in multiple networks, whereas in ASD they were limited to fewer systems. The clearest between-group inconsistency in age-related pattern was observed in the limbic network. CONCLUSION:These findings support the idea that normative brain development is associated with increasing linear organization of functional interactions, and suggest that this pattern is attenuated or altered in males with ASD. The proposed index quantifying the goodness of fit of the linear model predicting distance-correlation-based functional connectivity (FC) from Pearson-correlation-based FC and may provide an operational summary for characterizing atypical maturation of large-scale FC patterns.
脑性瘫痪(cerebral palsy,CP)简称脑瘫,是儿童时期最常见的引起运动功能障碍的疾病[1].我国于2013年完成的12省市自治区32万余名1-6岁儿童脑瘫流行病学调查结果显示,我国脑瘫患病率为2.46‰[2].在全球范围内,估计有1700万人患有脑瘫[3].虽然导致脑瘫的神经损伤是非进行性的,但是脑瘫儿童肌肉继发的病理变化会随着年龄的增长而进展[4].传统观点认为脑瘫儿童的骨骼肌只是脑损伤的终末器官,脑损伤引起的肌张力增高及长时间的姿势固定导致挛缩发生,但最新研究挑战了这一观点.脑瘫儿童肌肉病理形态的变化如结缔组织和脂肪增多、肌节形成异常、卫星细胞数量的减少和功能的下降等都与挛缩的发生有关[5].
脑性瘫痪(cerebral palsy,CP)简称脑瘫,是由一组持续存在的、导致活动受限的、中枢性运动和姿势发育障碍的症候群,这种症候群是由于发育中的胎儿或婴幼儿脑部非进行性损伤所致.CP的运动功能障碍常伴有感觉、知觉、认知、交流和行为障碍,以及癫痫和继发性肌肉、骨骼问题[1-3].据流行病学调查显示,脑瘫的发病率为0.2%-0.6%[4],目前治疗方法也多是采用综合康复治疗.而运动障碍是脑瘫患儿的主要表现形式,患有CP的儿童由于肌肉过度无力、关节运动学异常和姿势反应异常而表现出功能限制[5-6].脑瘫患儿的足部问题也是康复治疗过程中的重点和难点,研究表明,足部功能异常将直接影响到膝关节和髋关节受力、脊柱曲度以及相关部位的肌肉、韧带等软组织[7],会严重影响到患儿的平衡功能及步行能力.

The incidence of cerebral palsy (CP) is high in China, which brings huge economic burden to patients, families and society. Foot deformities such as scissors gait, flat foot, varus or valgus are the main manifestations of lower limb spasm in patients with spastic cerebral palsy. Cerebral palsy is a kind of non-progressive brain injury and nerve damage. At present, there is no effective treatment. If the foot deformity was not corrected for a long time, the muscles, fascia and ligament will change and contracture will occur, which can lead to secondary skeletal deformity, osteoarthritis of talocalcaneal, talonavicular and phalangeal joints, bony deformities of talocalcaneal joints and talonavicular joints, and miss the opportunity for passive traction correction. Patients with flat feet are prone to limb fatigue and pain when standing, walking, running and jumping for a long time, so it is necessary to screen and diagnose as soon as possible and implement rehabilitation training. Currently, there is no unified standard for the evaluation of foot deformity in children with CP. This review summarizes the evaluation methods for foot deformity in children with CP, mainly inclu-ding the principles, evaluation methods, advantages, disadvantages and scope of application of related evaluation tools for static analysis (footprint analysis, imaging evaluation, angle of standing calcaneus rest position, subtalar joint hardness, surface electromyography, etc.) and dynamic analysis (gross motor function grading system, Berg balance scale, plantar pressure system, etc.). The purpose is to provide reference for the diagnosis, rehabilitation treatment and rehabilitation outcomes evaluation of foot deformities in children with CP. The review found that the static analysis and evaluation method was mainly used for structure evaluation, while the dynamic analysis and evaluation method was mainly used for the evaluation of balance and motor function.
Objective . To evaluate the efficacy of psychotherapy in children with tic disorder and to provide basis for the application of psychotherapy in the treatment of children with tic disorder. Methods . A detailed search was conducted based on PubMed, Cochrane library database, CNKI, Wanfang Data, and VIP database to determine the randomized controlled trial (RCT) of psychotherapy combined with drugs and oral drugs in the treatment of tic disorder. The search time was from the establishment of the database to August 20, 2021. All kinds of extracted data are meta analyzed, and the statistical software used is Review Manager 5.3 software. Results . According to the inclusion and exclusion criteria, 14 clinical trials were finally included, including 513 TD children, including 267 in the psychological intervention group and 246 in the control group. All trials were conducted in China and published from 2013 to 2021. In terms of clinical efficacy, compared with the control group, the psychotherapy combined with drugs group had more advantages in improving the effective rate (RR = 3.25, 95% CI: 2.17~4.85, Z = 5.74, P < 0.00001) and improving the clinical symptoms of children with TD (WM = −5.36, 95% CI: -6.41 ~ -4.30, Z = 9.97, P < 0.00000 1). Conclusion . Psychotherapy as an adjuvant therapy for clinical treatment of TD can improve the clinical efficacy, but due to the low methodological quality of the existing trials, the research may have potential bias. In the future, large sample, multicenter, and double-blind randomized controlled trials need to be carried out to provide further support.
AbstractBackgroundThe EVEN‐plus syndrome (epiphyseal–vertebral–ear–nose dysplasia plus associated findings) is an extremely rare autosomal recessive inherited disease characterised by specific facial features and skeletal dysplasia. It has a prenatal onset due to defects in the HSPA9 gene. The syndrome has not been reported previously in China.MethodsThis study reported the characteristics, examination results, diagnosis and treatment of a female case aged 3 years and 3 months.ResultsThe patient had global developmental delay and specific facial features, including a prominent forehead, a bilateral auricle deformity, a collapsed nose, a high palatine arch, a short neck and other appearance abnormalities. Her hip joint magnetic resonance imaging (MRI) results showed bilateral femoral head epiphyseal dysplasia with a fork‐shaped malformation at the distal end, and her brain MRI showed white matter myelin dysplasia. HSPA9 compound heterozygous variants c.882_c.883delAG and c.613A>G were identified by exome sequencing.ConclusionsThis finding expands the spectra of EVEN‐plus syndrome phenotype and pathogenic variants and suggests that c.882_c.883delAG may have a higher distribution frequency in East Asian populations.

孤独症谱系障碍(austim spectrum disorder,ASD)是一种以社交和沟通障碍以及重复和限制性行为为特征的神经发育障碍.ASD的表型异质性使得确定核心症状涉及的确切病因和病理生理机制困难重重,且这些症状通常伴有注意缺陷多动障碍、癫痫发作和感觉运动异常等共患病.动物模型提供了阐明疾病的病因和发病机制的重要平台.越来越多的研究利用如环境暴露、母体免疫激活(maternal immune activation,MIA)等诱导的动物模型进行孤独症谱系障碍病因病机的探讨以及药物治疗靶点的筛选.该文综述常见动物模型的不同神经网络机制、脑组织及相关因子变化、症状表型等方面,为今后进行精准动物实验研究提供针对性的动物模型选择,也可为阐明疾病神经生物学、开发潜在的治疗药物提供参考.
手势先于语言产生,促进语言的发展.孤独症谱系障碍(ASD)儿童手势的类型和功能存在非典型使用及发展,手势-语言轨迹发展缓慢,可以成为ASD儿童的一个关键早期行为标记.手势的发展与后期语言、认知、社交和ASD诊断显著相关,应对ASD儿童的早期手势功能进行评估和监测.针对手势特点进行个性化训练,增加儿童社会参与和学习潜能,以手势为中介促进语言、认知及社交发展,提高康复效果.
孤独症谱系障碍(autism spectrum disorder,ASD)是一种起病于儿童早期的严重神经发育障碍性疾病,致残率极高,因此及时诊断和尽早治疗至关重要.ASD诊断方法的异质性和量表评估固有的主观性是ASD早期识别的障碍.弥散张量成像(diffusion tensor imaging,DTI)可通过相关参数量化呈现白质微观结构变化和脑发育情况,在ASD早期识别诊断中具有重要价值.本文围绕DTI技术及其在ASD诊疗方面的临床应用,提出DTI技术未来研究方向是探索ASD白质纤维束连接机制、归纳不同神经发育障碍性疾病的共同发育途径、分析全年龄组ASD患儿脑发育与行为学的纵向关联性,旨在阐明潜在神经病理学机制,为今后利用可视化技术寻求ASD生物标志物提供重要参考.

Autism spectrum disorder (ASD) is a complex disorder of neuropsychiatric development in children (American Psychiatric Association D S, 2013). The Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) is a 14-year revision that uses a large number of clinical studies as evidence-based to make leapfrog adjustments to many psychiatric disorders, including autism spectrum disorder. DSM-5 argues that autism spectrum disorder is characterized by social and communication disorders, repetitive stereotypes, and narrow interests. The prevalence of the disease is one in 54 in the United States, and the upward trend is obvious, placing a heavy burden on families and society (Persico et al., 2021). Due to the large base of Chinese population and the prevalence rate is still unclear, the China Colorful Deer Children ’ s Behavior Correction Center has found that by 2017, there were about three million children with autism spectrum disorder aged 0 – 14 in China, and the incidence is still growing, which means that patients with autism spectrum in China have become a huge medical group (Wucailu children ’ s behavior correction center, 2015). According to the statistics of the census of disabled persons in China, childhood autism has accounted for the fi rst place in China ’ s mental disabilities, but unfortunately there is no explicit report on the epidemi-ological investigation of the prevalence of autism spectrum disorder in China from 2017 to 2021. Early detection and early intervention are key to the clinical treatment of children with autism spectrum disorder (Siu A L et al., 2016). It is conducive to improving the core symptoms of children with ASD, helping children to integrate into society as soon as possible, and
全身振动训练(Whole-body vibration training,WBV)是一种神经肌肉训练方法,主要包含振动频率、振动强度和振动方式三个参数调控.训练过程中训练者站立、坐或半蹲在振动平台上,平台通过对人体施加振动波(通常使用5~60 Hz频率),刺激肌肉纺锤体和a运动神经元等感受器,使神经系统、肌肉-骨骼系统以及心血管系统产生适应性反应进而提高部分身体功能[1].早在1965年,Hagbarth等[2]就发现机械振动刺激会引起肌腹和肌腱的收缩性反应,并推广应用成为运动员训练的常用方法.随着研究的深入,学者们发现WBV还与骨密度、肌肉力量、平衡能力、步行速度、代谢和激素水平等生理参数有关[3],当躯体进行WBV时,可激活骨骼肌肉、调动神经反射通路、增加机体合成激素分泌[4-5],近年来WBV已单独或与其他干预措施联合应用于儿童,特别是运动障碍儿童康复,然而支持这种方法的证据有限.本文针对国内外研究现状,主要介绍了WBV在儿童康复中的作用及作用机制,以期为WBV相关研究与临床应用提供参考.
