Objectives: Caregiver-mediated intervention (CMI), based on parent skills training, is a family-mediated intervention model for children with neurodevelopmental disorders, in particular autism spectrum disorder. This study aimed to evaluate the effectiveness of CMI. Methods: Thirty-three children (aged 22-69 months from our department) and their...

MicroRNAs (miRNAs) are a type of endogenous non-coding short-chain RNA, which plays a crucial role in the regulation of many essential cellular functions, including cellular migration, proliferation, invasion, autophagy, oxidative stress, apoptosis, and differentiation. The lung can be damaged by pathogenic microorganisms, as well as physical or ch...

Abstract Background High prevalence of sleep problems have been reported in children with Autism Spectrum Disorder (ASD). This study aims to investigate the sleep conditions of ASD children in China, and explore the relationship between the common sleep problems and core symptoms and developmental levels. Methods Using a cross-sectional design, we...

Background Vitamin A deficiency (VAD) and sleep disturbances have been reported in children with autism spectrum disorder (ASD). The influence of vitamin A (VA) levels on sleep regulation and sleep disturbances in ASD has garnered concern. The present study aimed to characterize the association of VA levels with sleep disturbances in children with...

Background: We aimed to explore the risk profiles attributable to psychosocial and behavioural problems during the coronavirus disease 2019 pandemic. To this end, we created a risk-prediction nomogram model. Methods: A national multicentre study was conducted through an online questionnaire involving 12,186 children (6-11 years old) and adolescents...

This study aims to explore the psychosocial and behavioral problems of children and adolescents in the early stage of reopening schools. In this national cross-sectional study, a total of 11072 students from China were naturally divided into two groups based on their schooling status: reopened schools (RS) and home schooling (HS) group. The psychos...

Background: Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder. Folate has been demonstrated to be associated with ASD. However, current studies on the correlation between folate and symptoms of children with ASD have inconsistent conclusions, use mainly small samples, and lack age-stratified analysis. This study aimed to explo...

Objective: To study the association of serum levels of trace elements with core symptoms in children with autism spectrum disorder (ASD). Methods: From September 2018 to September 2019, an investigation was performed for 1 020 children with ASD and 1 038 healthy children matched for age and sex in the outpatient service of grade A tertiary hospi...

Background Chlamydia psittaci is a pathogen of birds that can cause zoonotic disease in mammals including pneumonia in humans. MicroRNAs (miRNAs) are a class of small non-coding RNA fragments with a length of about 22 nt, which play an important role in regulating gene expression after transcription. Chlamydia infection can cause changes in host ce...

Chlamydia psittaci is an important zoonotic factor associated with human and animal atypical pneumonia. Resisting host cell apoptosis is central to sustaining Chlamydia infection in vivo. Chlamydia can secrete inclusion membrane proteins (Incs) that play important roles in their development cycle and pathogenesis. CPSIT_0846 is an Inc protein in C....

Background: The etiology of autism spectrum disorder (ASD) has not yet been fully identified, but it seems to be triggered by complex genetic and environmental risk factors. Moreover, the tremendous etiological and clinical differences among individuals with ASD has had a major negative impact on early diagnosis and individualized treatment. Earlie...

Background: The Caregiver-Mediated Intervention(CMI), based on Parent Skills Training(PST), is one family-mediated intervention model for children with neurodevelopmental disorders(NDDs), especially for ASD. This study aims to evaluate the effectiveness of CMI. Methods: 33 children (aged 22-69 months from our department) and their caregivers were i...

Background: Vitamin A deficiency (VAD) and sleep disturbances have been reported in children with autism spectrum disorder (ASD). The influence of vitamin A (VA) on sleep regulation and sleep disturbances in ASD has garnered increased attention. This study aims to characterize the effect of VA levels and sleep disturbances on children with ASD. Met...

Objective: To explore the role of tumor necrosis factor-α (TNF-α) in immune response to urogenital chlamydial infection and urogenital pathology in mice. Methods: Fifteen female wild-type (WT) C57BL/6J mice and 15 TNF-α receptor knockout (TNF-αR KO) mice were inoculated intravaginally with 1×104 inclusion forming units (IFUs) of live C.muridarum...

Chlamydia psittaciis a well known zoonotic pathogen that can lead to severe respiratory disease in poultry, pet birds and humans. Development of an effective and safe vaccine would be the most effective way to control C. psittaci infection. In this study, we used bacterial ghosts (BGs) as a delivery vehicle to evaluate the protective effects of maj...

Background It is unclear whether increased head circumference (HC) is actually an artifact of an overall overgrowth phenomenon or specific to the brain at all in autism spectrum disorders. This study compared the head circumferences, body weight and height of ASD children with a control group. We also discuss whether HC, body weight and height are...

Deposition of amyloid β protein (Aβ) to form neuritic plaques in the brain is the unique pathological hallmark of Alzheimer’s disease (AD). Aβ is derived from amyloid β precursor protein (APP) by β- and γ-secretase cleavages and turned over by glia in the central nervous system (CNS). Vitamin A deficiency (VAD) has been shown to affect cognitive fu...
