Objective: To analyse the effects of physical activity on neurocognitive function in children with autism spectrum disorder (ASD),so as to provide a theoretical basis and specific guidance for the clinical cognitive function rehabilitation practice of ASD children. Methods: Relevant literature on the effects of physical activity on neurocognitive function in children with ASD were searched in the China National Knowledge Infrastructure (CNKI), Wanfang, Web of Science, and EBSCO databases from their inception to March 2024 using specific subject terms. Information on authors, countries, publication dates, study populations, diagnostic criterion, interventions, measurement tools and study results were extracted postscreening. The methodological quality of the articles was assessed using the PEDro Scale, followed by a systematic review. Results: A total of seventeen articles and were included in the study and English literature, most of them were of good quality. The study included 10 randomized controlled trials, 4 quasiexperimental designs, and 3 preand posttest designs. The rehabilitative effects of physical activity on children with ASD were primarily observed in enhanced attention and executive function, as well as improvements in brain structure and function. Children with ASD showed varying cognitive effects in physical and skillbased programs, with skillbased activities like basketball and table tennis notably improving cognitive function. Conclusion Physical activity is an effective intervention that enhances cognitive abilities such as attention and executive function, as well as brain structure and function in children with ASD.

Objective To explore the affect of physical activity on neurocognitive function of overweight children.Methods The literatures about the effect of physical activity on neurocognitive function of overweight children were retrieved with subjected retrieval method in CNKI, VIP, Wanfang database, PubMed, Web of Science, EBSCO databases from January, 2000 to January, 2022. The authors, countries, published years, ages of subjects, research methods, intervention time, measurement tools and measurement indicators were extracted.Results Twelve articles were selected finally. These articles came from United States, Italy, Belgium and China, were mainly published in journals of psychology, clinical medicine, neuroscience, physical education. The study design included randomized controlled trials and pre-post-trial. The mean PEDro score was 6.67. The types of physical activity included fitness, skills and sports activities. The overweight children participating in physical activities could benefit from cognition and brain plasticity. On the cognition, physical activity could improve attention, memory, inhibitory control, working memory and cognitive flexibility. In terms of brain plasticity, physical activity could improve the integrity of brain white matter, increase hippocampal volume, enhance brain activation and brain network connectivity.Conclusion Physical activity is a simple and effective form of exercise. It can improve not only attention, memory, executive function and other cognitive functions, but also brain structure and brain function in overweight children. The mechanism of cognition, the interaction between physical activity and other factors, and the dose-relationship between physical activity and cognitive benefits still need to be explored in the future.

ObjectiveTo review the application of artificial intelligence in anxiety and depression among children and adolescents. MethodsPubMed, Web of Science, CNKI and Wanfang data were searched for literature related to artificial intelligence applied in of anxiety and depression among children and adolescents from January, 2014 to January, 2024, and a scoping review was conducted. ResultsA total of ten papers were included, originating from the United States, China, Australia and France. These researches were primarily published in journals related to psychology, public health, clinical medicine, neuroscience and rehabilitation, involving six cross-sectional researches, three longitudinal researches and one interview, including 10 880 participants aged from three to 18 years. The types of data mainly included questionnaires/scales, interview data and brain imaging data. Features related to anxiety and depression were extracted from the data, and artificial intelligence were employed to develop models for the identification or prediction of anxiety and depression in children and adolescents. ConclusionArtificial intelligence is potential for identifying or predicting anxiety and depression in children and adolescents.

ObjectiveTo establish the categories and structure of physical activity in children with autism spectrum disorder (ASD), and systematically evaluate the long-term effect of physical activity on the executive function of children with ASD, based on the theoretical and methodological framework of the International Classification of Functioning, Disability, and Health-Children and Youth version (ICF-CY). MethodsA search was conducted in databases such as Wanfang data, CNKI, PubMed, Web of Science and ProQuest, to collect literatures about long-term physical activity for executive function of children with ASD published from 2014 to 2023. The literatures were reviewed based on inclusion and exclusion criteria, following PRISMA guidelines for systematic review, and the quality of the included literatures were assessed with the Physiotherapy Evidence Database (PEDro) scale. ResultsTotally, ten articles were included, consisting of nine randomized controlled trials (RCTs) and one non-randomized controlled trial, with a total of 351 children diagnosed as ASD, aged three to 18 years, came from Italy, Canada, South Korea, China and the United States, published mainly after 2016. Physical activity primarily included sports activities (such as baseball, basketball, table tennis and equine-assisted activities), skill-based activities (such as cycling, cognitive-motor training and active gaming), physical fitness activities (SPARK), as well as combat-related activities (martial arts and karate); 30 to 70 minutes a time (mainly 45 minutes), one to five times a week (mainly twice a week), for two to 24 weeks (mainly twelve weeks). Long-term physical activities had been found to improve inhibitory control and cognitive flexibility in children with ASD, although the effect on working memory was inconsistent. ConclusionLong-term physical activity may positively impact on executive function in children with ASD, especially inhibitory control and cognitive flexibility. However, the effect on working memory need more researches.

ObjectiveTo observe the effect of twelve-week aerobic exercise on inhibitory control abilities and the change of brain activation in overweight children. MethodsFrom October to December, 2021, 20 overweight children from a primary school in Changping District were selected for a twelve-week aerobic exercise intervention. Their inhibitory control abilities were measured by Flanker task before and after intervention, while their brain activation levels during the task were detected by functional near infrared spectroscopy (fNIRS). ResultsThe interactions between task type and time of accuracy and reaction time in inconsistent tasks Flanker task were significant (F > 9.277, P < 0.05), with higher accuracy and lower reaction time of after intervention (P < 0.05). After intervention, ch1, ch2, ch3, ch6, and ch8 channels were activated by inconsistent tasks (P < 0.05). ConclusionA twelve-week aerobic exercise intervention could improve the inhibitory control ability, and increase the prefrontal cortex activation during inconsistent tasks in overweight children.

BACKGROUND: Airway stents has been widely used in airway stenosis and fistula, yet clinical date of airway stents in reestablishment a complex airway is insufficient. The aim of this study is to evaluate the efficacy and safety to combine the silicon stent and the metal stent in reestablishment a complex malignant airway. METHODS: Patients with non-operable complex malignant airway stenosis and fistula were recruited in this study. Silicon Y stent combined with covered metal stent (Hybrid stent) were inserted to reestablishment the airway. Clinical outcomes and complications were observed over six months. RESULTS: A total of 23 silicon Y stents and 25 covered metal stents were inserted in 23 patients. Nineteen of 23 (19/23, 82.6%) patients felt a immediately relieving of current symptoms. The mean duration of stents placement in patients was (153.43±9.14) days. The modified British Medical Research Council, Karnofsky Performance Status and Performance Status scale were improved significantly after stenting. A total of 12 patients living with stent at 6 months. Others dead of tumor progression. There were no death or immediate complications related to hybrid stenting implication. CONCLUSIONS Hybrid stenting proved to be useful and was well-tolerated in the management of complex malignant airway stenosis and fistula.
