Autism spectrum disorder(ASD) comprises neurodevelopmental disorders characterized by core symptoms of social communication disorders, restricted interests, and repetitive behaviors.With increasing incidence year by year, ASD may persist throughout life.The current clinical treatment is mainly behavioral intervention, occasionally supplemented with medication to treat the accompanying symptoms, such as irritability, paresthesia, sleep disorders, and gastrointestinal diseases, but there is still a lack of specific drugs targeting the core symptoms of ASD.Bumetanide, an U. S.Food and Drug Administration-approved diuretic, has been proposed as a candidate to treat the core symptoms of ASD.This article mainly reviews the latest research progress on Bumetanide treatment of core symptoms in children with ASD, providing a theoretical basis for the research and application of Bumetanide.

Autism spectrum disorder (ASD) are a complex group of neurodevelopmental disorders. High heritability in ASD is still controversial, but epigenetics can better explain the pathogenesis of ASD and make up the lack of heritability research. This review discusses the role of epigenetic modification in ASD pathogenesis by analyzing the related research on epigenetic mechanism of ASD at home and abroad, in order to provide new treatment ideas and theoretical basis for clinical practice.

Developmental coordination disorder (DCD) is a developmental disorder that mainly affects children′s motor coordination.The prevalence of DCD in childhood is very high, and it seriously affects the physical and mental health of school-age children.In China, this disease has not yet been fully recognized and understood.There is a lack of standardized and unified diagnostic criteria, and the standardization of relevant clinical assessment tools and the establishment of normative models are insufficient.In addition, the clinical practice and experience of most health professionals in dealing with DCD appear to be limited.Based on international clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD issued by the European Academy of Childhood Disability in 2019, the recommendations related to the diagnosis, evaluation and intervention of DCD in the guidelines were compiled and interpreted in the light of the current clinical practice and research in China.The objective of this study is to bring DCD to the attention of more domestic medical experts through the interpretation of this international guideline and to provide preliminary guidance on the clinical diagnosis, assessment, and intervention of DCD.

Attention deficit/hyperactivity disorder (ADHD) is one of the most common neuro developmental disorders in childhood.The main symptoms of ADHD are inattention, hyperactivity, impulsivity, etc.ADHD causes lots of adverse effects on patients, families and the society.Currently, medication is a common treatment for ADHD.However, due to a series of adverse effects caused by drug treatment, and some concomitant problems, the effect of drug treatment alone is not ideal.Therefore, non-drug treatment of ADHD is becoming popular.This study aims to review the common non-drug treatment methods and efficacy of ADHD at home and abroad.

Objective To investigate the epidemiological characteristics of cerebral palsy(CP)in children aged 1-6 years in China,including the incidence,prevalence,type of CP,etiology,prevention and rehabilitation status. Methods The survey was carried out by standard questionnaires,multi-center collaboration,stratified-cluster ran-dom sampling method.The surveyed adopted the following principles:streets in the city and villages in the rural areas, and the number of the urban and rural children was the same,and the proportion of children in each age group was balanced.The investigation areas included provinces and autonomous regions,including Heilongjiang,Beijing,Henan, Shandong,Shanxi,Shaanxi,Anhui,Hunan,Guangxi,Guangdong,Chongqing and Qinghai,and 323 858 children were in-vestigated.Results The incidence of CP was 2.48‰(155/62 591 cases),and the prevalence was 2.46‰(797/323 858 cases)(1-6 years old).The prevalence varied in different regions,in which the highest prevalence was 5. 40‰(54/9 998 cases)in Qinghai province,and the lowest prevalence was 1.04‰(47/45 133 cases)in Shandong province.The prevalence of the males(2.64‰,461/174 391 cases)was higher than that of the females(2.25‰, 336/149 467 cases),and the difference was statistically significant(P<0.05).The types of CP were spastic type (58.85%,469/797 cases),mixed type(13.17%,105/797 cases),dyskinetic(9.79%,78/797 cases),hypotonic (8.28%,66/797 cases),ataxia(6.25%,52/797 cases)and rigid(3.39%,27/797 cases)respectively in 797 CP children.The first three risk factors for CP were long -term exposure to harmful physical factors during pregnancy, whether there were birth defects among the three generations of relatives of the children,such as children's peers, parents or grandparents,whether there were birth defects among the children's peers,parents or grandparents,and neonatal jaundice or persistent jaundice.Among 797 CP children,79.67% of the children with CP were timely detected and treated in the local hospitals,while the other 19.93% of them were not timely treated.The places which could give them timely detection and early diagnosis and treatment were general hospitals(42.97%),Maternity and Infant Hospitals (27.03%)and Children's Hospitals(20.31%). The main rehabilitation methods for 797 children with CP were 34.58% in the hospitals or rehabilitation centers,31.61% in the communities(including at home),33.80% mainly in the medical institution,and in the communities they could also receive partially rehabilitation services. Conclusions The prevalence of CP in China is coincident with international levels.The prevalence rate of CP in males is higher than that in females.The types of CP distribution are accorded with international distribution characteristics.There were still some children with CP who could not receive timely detection and treatment.Rehabilitation at the medical institutions is the chief way and proper rehabilitation guidance should be carried out in the communities.

Autism spectrum disorders (ASD) is a neurodevelopmental condition characterized by altered social communication,alongside restricted and stereotyped behaviors and interests,bringing a heavy burden to the family and society.International experts develop the International Classification of Functioning,Disability and Health (ICF) core sets for individuals with ASD.The ICF core sets for ASD will be a tool to describe individual functioning comprehensively.

Objective To explore the mental health and personality traits of the parents of cerebral palsy children. Methods 128 parents of cerebral palsy children and other 128 parents of healthy children were investigated with the Symptom Check List-90 (SCL-90), Eysenck Personality Questionnaire (EPQ). Results The scores of SCL-90 were more in the parents of cerebral palsy children, especially in the factors of somatization, obsession, depression, anxiety, and paranoid (P<0.01). The personality traits characterized as introversion (P<0.05) and neuroticism (P<0.01). The multiple regression showed that some factors of SCL-90 were related with the personality of neuroticism. Conclusion The mental health of the parents of children with cerebral palsy are poor, which may be related with the personality of neuroticism.

Objective To explore the role of Bcl-2 and Bax in pathogenesis of the autism. Methods Female Sprague-Dawley rats were given a single intraperitoneal injection of sodium valproate (VPA, 600 mg/kg) on 12.5 d after pregnancy, their offspring were as the model group; while the other pregnancy rats were given normal saline, their offspring were as the control group. Both groups were observed with the Nissl staining, immunohistochemistry of Bcl-2 and Bax and image analysis 1 d, 7 d, 14 d, 28 d, 56 d after birth. Results Compared with the control group, Nissl staining showed the number of cortical neurons decreased on 1 d and 7 d after birth in the model group, rapidly increased on 14 d after birth, and maintained in high level on 28d , 56 d after birth. For immunohistochemistry, the integrated optical density (IOD) of Bcl-2 and Bax decreased in cortex on 1~14 d after birth (P<0.001) in both groups, and were stable 28 d after birth (P>0.05). Compared with the control group, the IOD of Bcl-2 decreased much more at every time point (P<0.001) in the model group, but the IOD of Bax increased on 1 d, 7 d (P<0.001), decreased on 14 d (P<0.001), similar 28 after birth(P>0.05). The ratio of Bcl-2/Bax was the most on 1 d after birth, and then decreased to approximately 1 in the control group, while it was the least on 7 d, most on 14 d, and decrease to less than 128 d after birth. Conclusion Apoptosis of cerebral cortex neurons increases in the autism model rats, especially in the early time.

Objective To study the validity of Dynamic Occupational Therapy Cognitive Assessment for Children (DOTCA-Ch) on the cognitive function of children with cerebral palsy. Methods 30 children with cerebral palsy were assessed with DOTCA-Ch and Chinese Binet Test of Intelligence by trained rehabilitation medicine graduates within 1 week. The correlation between these tests were analyzed. Results The total DOTCA-Ch scores, spatial orientation and thought operation function were strongly correlated with IQ, while spatial perception,praxis and optomotor tissue were slightly correlated with IQ. Conclusion DOTCA-Ch can comprehensively assess the cognitive function of children with cerebral palsy.
