ABSTRACT

BACKGROUND: Limited study has investigated the influence of parent-child interaction on brain functional alterations and development outcomes of autism spectrum disorder (ASD) children. This pilot study aimed to explore the relationship between parent-child interaction, brain functional activities and development outcomes of ASD children. METHODS: and Procedures: 653 ASD with an average age of 41.06 ± 10.88 months and 102 typically developmental (TD) children with an average age of 44.35 ± 18.39 months were enrolled in this study, of whom 155 ASD completed brain rs-fMRI scans. The amplitude of low-frequency fluctuations (ALFF) and regional homogeneity (ReHo) measured using resting-state functional magnetic resonance imaging (rs-fMRI) data reflect local brain function. The parent-child interaction was assessed by the Chinese Parent-child Interaction Scale (CPCIS). Childhood Autism Rating Scale (CARS) and developmental quotient (DQ) indicated development outcomes. OUTCOMES AND RESULTS: Total CPCIS score was negatively correlated with CARS total score, and positively correlated with DQ. The frequency of parent-child interaction was negatively correlated with ALFF values in the left median cingulate and paracingulate gyri (DCG.L) and ReHo values in the right superior frontal gyrus, medial (SFGmed.R)(P < 0.05, FDR correction). ALFF values in the DCG.L and ReHo values in the SFGmed.R play complete mediating roles in the relationship between parent-child interaction and performance DQ. CONCLUSION AND IMPLICATIONS: This study suggest that parent-child interaction has an impact on autistic characteristics and DQ of ASD children. Local brain regions with functional abnormalities in the DCG.L and SFGmed.R may be a crucial factors affecting the performance development of ASD children with reduced parent-child interaction.

ABSTRACT

Objective: To analyze the risk factors for developmental quotients (DQs) of children with autism spectrum disorder (ASD) and to better understand the effects of screen time on neurodevelopment in children with ASD. Methods: We retrospectively analyzed the data of 382 children with ASD, including demographic profiles; socioeconomic status; score on the Chinese parent-child interaction scale (CPCIS); screen time questionnaire; ASD symptom rating scales, including the Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), and Autism Diagnostic Observation Schedule Second Edition (ADOS-2); and DQs using Griffiths Development Scales-Chinese Edition. Univariate analysis was carried out to analyze the factors related to the DQs of children with ASD, and then the linear regression model was used to identify the independent influencing factors of the DQs of children with ASD. Results: Vitamin D (ß = 0.180, p = 0.002), age (ß = -0.283, p = 0.000) and CARS score (ß = -0.347, p = 0.000) are risk factors related to DQ of locomotor in children with ASD. Vitamin D (ß = 0.108, p = 0.034), CARS score (ß = -0.503, p = 0.000), ADOS-2 severity score (ß = -0.109, p = 0.045) and CPCIS score (ß = 0.198, p = 0.000) are risk factors related to DQ of personal social skill in children with ASD. Vitamin D (ß = 0.130, p = 0.018), CARS score (ß = -0.469, p = 0.000), and CPCIS score (ß = 0.133, p = 0.022) are risk factors related to DQ of hearing-speech in children with ASD. Vitamin D (ß = 0.163, p = 0.003) and CARS score (ß = -0.471, p = 0.000) are risk factors related to DQ of eye-hand coordination in children with ASD. Age (ß = -0.140, p = 0.020), CARS score (ß = -0.342, p = 0.000), ADOS-2 severity score (ß = -0.133, p = 0.034) and CPCIS score (ß = 0.193, p = 0.002) are risk factors related to DQ of performance in children with ASD. Vitamin D (ß = 0.801, p = 0.000) and CPCIS score (ß = 0.394, p = 0.019) are risk factors related to DQ of practical reasoning in children with ASD. Conclusion: Vitamin D status, the severity of autistic symptoms and parent-child interaction are risk factors for developmental quotients in children with ASD. Screen exposure time is negatively associated with DQs in children with ASD but is not an independent risk factor for DQs.

ABSTRACT

BACKGROUND: The prevalence of autism spectrum disorder (ASD) has increased rapidly in recent years. Environmental factors may play an important role in the pathogenesis of ASD. These factors may include socioeconomic factors, nutritional factors, heavy metal exposure, air pollution, etc. Our aim is to analyze possible environmental factors associated with the severity of ASD. METHODS: All participating children were divided into two groups (mild and moderate/severe) according to the severity of their symptoms, as determined by their Childhood Autism Rating Scale (CARS) scores. The socioeconomic, demographic factors and the nutritional factors that may affect the severity of ASD were included in the logistic regression to analyze whether they were predictors that affected the severity of ASD. RESULTS: Logistic regression showed that caregivers(P = 0.042), maternal education (P = 0.030), gastrointestinal problems (P = 0.041) and a high serum concentration of lead (P = 0.003) were statistically significantly associated with ASD severity. CONCLUSION: Many environmental factors affect the severity of ASD. We concluded that non-parental caregivers, low maternal education, gastrointestinal problems and high blood lead level maybe predictors that affected the severity of ASD in northeast China.

ABSTRACT

Objective: To investigate the current status of screen time in children with ASD, its correlation with autistic symptoms and developmental quotient (DQ), and the factors affecting screen time. Method: One hundred ninety-three Chinese children with ASD were recruited. We collected the demographic and screen time data using a questionnaire. The ASD core symptoms and developmental quotient (DQ) were measured by the Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), Autism Diagnostic Observation Schedule-Second Edition (ADOS-2), Griffiths Development Scales-Chinese Language Edition (GDS-C), and Chinese Children's Parent-Child Relationship Questionnaire (CPCIS). Then, we analyzed the correlations between the screen time of children with ASD and the ABC, CARS, ADOS, GDS-C DQs, and CPCIS scores. Linear regression was used to analyze the risk factors that affect screen time. Results: The children's average daily screen time was 2.64 ± 2.24 h. Forty eight percent children were exposed to two or more types of electronic devices. Their favorite activity of screen time was watching cartoons. Only 34% children spent screen time accompanied by parents and with communication. 50.26% children had no screen time before sleeping. The screen time of children with ASD had a negative correlation with the GDS-C CQ (r = -0.234, P = 0.001) and the CPCIS score (r = -0.180, P = 0.012) and a positive correlation with the CARS score (r = 0.192, P = 0.009). A low father's education level (P = 0.010), less restriction of the child's screen time by the guardian (P = 0.001), greater caregiver screen time (P < 0.001), the use of the screen as a tool for child rearing (P = 0.001), and the child's ownership of independent electronic equipment (P = 0.027) are risk factors for long screen time in children with ASD. Conclusion: The screen time of children with ASD in China is higher than the recommended standard, and the current situation is serious. The screen time of ASD children is related to their autism symptoms, DQ and parent-child interaction. Low paternal education levels, less restriction of children's screen time by guardians, greater guardian screen time, the use of screens in child rearing, and children's ownership of independent electronic equipment can lead to an increase in children's screen time. These findings may have implications for family intervention strategies.

ABSTRACT

BACKGROUND: Previous studies have mostly explored the comorbidities of Global developmental delay (GDD) in children with Autism Spectrum Disorders (ASD) from the perspective of ASD. The study focus on the perspective of GDD to investigate the prevalence and developmental profiles of ASD in GDD and to explore the correlation between the developmental level and symptoms of autism. METHODS: Clinical data of 521 children with GDD aged from 24 to 60 months were retrospectively analyzed. Analyses were performed first for the whole sample and then subdivided into two subgroups (GDD+ASD-, GDD+ASD+) according to whether had ASD. Symptoms of autism were evaluated by the Autism Behavior Checklist and the Childhood Autism Rating Scale. The Chinese version of the Gesell Developmental Schedules was used to evaluate the level of children's mental development. RESULT: The prevalence of ASD in children with GDD was 62.3%. The total average developmental quotient (DQ) of GDD was mildly deficient and was negatively correlated with symptoms of autism (p < 0.05); language ability was severe and extremely severe deficient (P < 0.05). GDD+ASD- group and GDD+ASD+ group have some common points as well as differences in the developmental features. The language delay of children in both subgroups was the most obviously defected, thereafter followed by the item of personal social activity. In the GDD+ASD+ group, the DQ of gross motor skills>fine motor skills>adaptability (p < 0.05). There were no significant differences among the DQ of gross motor skills, fine motor skills and adaptability in GDD+ASD- group (p > 0.05). The GDD+ASD-group had better adaptability, fine motor skills, language ability, personal social activity than that of the GDD+ASD+ group, but the gross motor skills in GDD+ASD- group were worse (p < 0.05). CONCLUSION: GDD children have a high proportion of comorbid ASD, and GDD children with poorer developmental levels are more likely to have ASD symptoms. Development profiles in both GDD+ASD- children and GDD+ASD+ children have common features but there are also differences. GDD+ASD+ group is worse than GDD+ASD- group in terms of the overall development level.

ABSTRACT

Objective: To measure levels of vitamin A (VA) and vitamin D (VD) and the symptomatic association of their co-deficiencies on attention deficit hyperactivity disorder (ADHD) in Chinese children (6-9 years). Methods: Eighty-two children (69 boys and 13 girls; mean age = 7.1 ± 0.9 years at the time of the diagnosis) with ADHD were recruited as ADHD group. A total of 106 healthy children were recruited as the healthy control (HC) group. Serum levels of retinol and 25-hydroxyvitamin D (25(OH)D) of all children were evaluated using high-performance liquid chromatography (HPLC) and HPLC-tandem mass spectrometry. The Swanson, Nolan, and Pelham IV Rating Scale (SNAP-IV) was employed to assess the clinical symptoms of ADHD. Results: Children suffering from ADHD had significantly reduced serum levels of retinol and 25(OH)D compared with those of HCs, and the prevalence of VA deficiency and VD deficiency were higher in children suffering from ADHD. Serum concentrations of 25(OH)D and retinol were linked closely with the presence or absence of ADHD after adjustment for age, body mass index, season of blood sampling, and sun exposure. Serum concentrations of 25(OH)D and retinol showed a negative correlation with the total scores of SNAP-IV. Children with ADHD as well as VA and VD co-deficiency had increased SNAP-IV total scores and ADHD inattention subscale scores. Conclusion: VA deficiency and VD deficiency in children with ADHD were increased in comparison with that in HCs. VA and VD co-deficiency associated with ADHD symptom severity. Attention should be paid to regular testing of VA levels and VD levels. However, the mechanism of VA and VD in ADHD needs to be further studied. Interventional studies on VA and VD supplementation are recommended to further verify the relationship between VA and VD co-deficiency and ADHD.

ABSTRACT

The purpose of this study was to profile the mental development of children aged 18 to 96 months with autism spectrum disorder (ASD) using the Chinese version of the Griffiths Mental Development Scales (GMDS), and to explore the relationships between developmental levels and ASD severity, the sex of the child and the age of ASD diagnosis. Children with ASD (n = 398; 337 boys, 61 girls) were recruited and ASD severity evaluated using the Autism Behavior Checklist and the Childhood Autism Rating Scale, while the GMDS was used to evaluate the children's mental development. Study participants were divided into groups according to GMDS general and subscale quotients, ASD severity, sex, and age. The majority of groups divided according to the GMDS quotients exhibited an unbalanced distribution in respect of the six domains of the GMDS and there were significant differences within the six subscale quotients. Autism severity, sex and age had significant effects on the overall level of development of autistic children. The quotients recorded for the children with more severe ASD were significantly lower than those for the children with less severe ASD. A markedly higher proportion of developmental delay was recorded for girls than boys in relation to the performance subscale. The locomotor quotient decreased in line with age at diagnosis, while autism severity and age had significant effects on the general and subscale quotients and sex had a significant effect on performance quotient. Children with ASD exhibit an uneven cognitive development profile, and their overall developmental levels are affected by autism severity, sex and age. Specific cognitive domains differ according to sex in children with ASD. Locomotor skills tend to decrease according to the age at diagnosis for autistic children aged 18 to 84 months. Autism severity and age are also associated with the level of functioning in different cognitive areas. These findings contribute to define the cognitive developmental profiles of children with ASD.

ABSTRACT

RATIONAL: Tyrosine hydroxylase deficiency (THD) is a rare cause of dopa-responsive dystonia (DRD). Although the symptoms of DRD may be improved by treatment with L-dopa, the low morbidity of THD can lead to its misdiagnosis. Thus, it is important for physicians to be aware of THD as a cause of DRD. PATIENT CONCERNS: We report 3 cases of THD. A 5-year-old boy with DRD was diagnosed with THD and found to have compound heterozygous mutations of the TH gene, including TH:c.647G>C from his mother and TH:c.646G>A from his father. Two female siblings also were found to have TH:c.698G>A from their mother and TH:c.710T>C from their father. The younger daughter, at age 3.5 years, was diagnosed with DRD caused by THD, and then the diagnosis of the older daughter, at age 11 years, was changed from cerebral palsy to DRD caused by THD. DIAGNOSIS: The diagnosis of dopa-responsive dystonia caused by tyrosine hydroxylase deficiency was determined by whole exome sequencing. INTERVENTION: They all treated with low dose levodopa and benserazide tablets. OUTCOMES: The boy had a very good therapeutic effect, and he could walk very well by the second day of treatment. The younger sister of the siblings had a partial therapeutic effect, but her elder sister was only little effective with a milder improvement of dystonia and improvement of myodynamia. CONCLUSION: The characteristics of THD are heterogeneous, and its phenotypes are classified as type A or type B according to increasing severity. Generally, L-dopa has a good therapeutic effect in cases with type A phenotypes. We reviewed 87 cases of reported in the literature and found that c.698G>A and c.707T>C are hot spot mutations. Changes on cerebral magnetic resonance imaging were nonspecific. Analysis of neurotransmitter levels in cerebrospinal fluid is an invasive means of achieving a biochemical diagnosis.

ABSTRACT

RATIONALE: Autism spectrum disorder (ASD) is a common neurodevelopmental disorder caused by complex interactions between genetic and environmental factors. Recent studies suggest that Vitamin D3 or bumetanide therapy may improve the core symptoms of ASD in some individuals. However, there are no guidelines that provide clinicians with evidence-based treatment regimens for the use of these therapies in ASD. PATIENT CONCERNS: A 30-month-old female was referred to our department because she did not respond when her name was called. DIAGNOSIS: The patient was diagnosed with ASD by a team of autism experts according to American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. INTERVENTIONS: The patient was administered Vitamin D3 150,000 IU intramuscularly once a month and Vitamin D3 800 IU orally each day. After 6 months, Vitamin D3 supplementation was discontinued because of lack of effectiveness. Subsequently, oral bumetanide 0.5 mg twice daily was initiated. OUTCOMES: The patient's symptoms remained unchanged after 6 months of Vitamin D3 supplementation, and her serum 25 (OH) D levels had reached 52.4 ng/mL. At the parent's request, Vitamin D3 supplementation was discontinued because of lack of effectiveness. Thereafter, bumetanide was initiated. After 1 month of bumetanide, the patient's Childhood Autism Rating Scale score was 26, which is below the cutoff score for ASD. This case report suggests that Vitamin D3 and bumetanide target different mechanisms in the pathogenesis of ASD. LESSONS: Based on these observations, we discuss three possible scenarios for Vitamin D3 supplementation and propose that bumetanide should be initiated if Vitamin D3 supplementation is ineffective (identifier ChiCTR-CCC-13004498).

ABSTRACT

BACKGROUND: The newly revised Children Neuropsychological and Behavior Scale (CNBS-R2016) is a diagnostic assessment tool widely used in China to assess the developmental level of children aged 0 to 6 years. The purpose of this study was to determine whether the effectiveness of developmental assessment in children with autism spectrum disorder (ASD) by the CNBS-R2016 was consistent with that of the Griffiths Mental Development Scales for China (GDS-C). METHODS: In total, 139 children with ASD were recruited in this study. The Autism Behavior Checklist (ABC) and the Childhood Autism Rating Scale (CARS) were used to measure ASD severity. All subjects were evaluated with both the CNBS-R2016 and GDS-C. To determine the consistency between the CNBS-R2016 and GDS-C, Pearson correlation coefficients and Bland-Altman plots were computed. The GDS-C was used as a reference assessment, and the performance of the CNBS-R2016 was analyzed with receiver operating curves. RESULTS: No significant difference was found between the proportions of developmental delays detected by the CNBS-R2016 subscales and the corresponding GDS-C subscales. The CNBS-R2016 Communication Warning Behavior subscale quotients and the total ABC and CARS scores were significantly and positively correlated. The general and subscale quotients of the CNBS-R2016 and the corresponding quotient of the GDS-C were also significantly and positively correlated. The area under all the curves of the CNBS-R2016 was above 0.8 according to the results of the GDS-C (general or subscale quotient <70 indicates a developmental delay), and Bland-Altman plots showed no systemic bias between the two scales. CONCLUSION: The CNBS-R2016 and GDS-C tests showed good consistency in the developmental assessment of children with ASD. In addition, the CNBS-R2016 allows the simultaneous assessment of autism symptoms and the developmental level. Therefore, the CNBS-R2016 is worthy of clinical application in children aged 0-6 years.

ABSTRACT

BACKGROUND: Increasing studies have focused on motor function/dysfunction in PICU survivors; however, most studies have focused on adults and older children. This study investigated gross motor developmental function outcomes in infantile and toddler pediatric intensive care unit (PICU) survivors and the factors associated with gross motor developmental functions. METHODS: This observational study was conducted in the PICU of the First Hospital of Jilin University between January 2019 and March 2019. Thirty-five eligible patients were divided into the dysfunctional (n = 24) or non-dysfunctional (n = 11) group according to the results of the Peabody Developmental Motor Scales, Second Edition (PDMS-2). Baseline gross motor function for all participants before PICU admission was measured via the Age and Stages Questionnaires, Third Edition (ASQ-3). The PDMS-2 was used to evaluate gross motor development function before PICU discharge. RESULTS: The gross motor developmental dysfunction incidence was 68.6%. Linear correlation analysis showed that the gross motor quotient (GMQ) was positively correlated with the pediatric critical illness score (PCIS, r = 0.621, P < 0.001), and negatively correlated with length of PICU stay (r = - 0.556, P = 0.001), days sedated (r = - 0.602, P < 0.001), days on invasive mechanical ventilation (IMV; r = - 0.686, P < 0.001), and days on continuous renal replacement therapy (CRRT; r = - 0.538, P = 0.001). Linear regression analysis showed that IMV days (ß = - 0.736, P = 0.001), sepsis (ß = - 18.111, P = 0.003) and PCIS (ß = 0.550, P = 0.021) were independent risk factors for gross motor developmental dysfunction. CONCLUSIONS: Gross motor developmental dysfunction in infantile and toddler PICU survivors is more common and may be exacerbated by experiences associated with longer IMV days and increasing illness severity combined with sepsis. TRIAL REGISTRATION: The trial 'Early rehabilitation intervention for critically ill children' has been registered at http://www.chictr.org.cn/showproj.aspx?proj=23132. Registration number: ChiCTR1800020196.

ABSTRACT

OBJECTIVE: To study the clinical effect of vitamin D3 (VitD3) combined with the Early Start Denver Model (ESDM) in the treatment of autism spectrum disorder (ASD) in toddlers. METHODS: A total of 102 toddlers with ASD, aged 1 to 3 years, were enrolled. According to the wishes of their parents, they were divided into conventional rehabilitation, ESDM and ESDM+VitD3 groups. Autism Behavior Checklist (ABC) and Childhood Autism Rating Scale (CARS) were used evaluate behavior problems before treatment and after 3 months of treatment. RESULTS: The conventional rehabilitation group had significant reductions in the total score and the scores on somatic movement and self-care subscales of the ABC scale after 3 months of treatment (P<0.05). After 3 months of treatment, the ESDM group had significant reductions in the total score and the scores on somatic movement, self-care, social interaction and language subscales of the ABC scale (P<0.05), as well as a significant reduction in the total score of the CARS (P<0.05). After 3 months of treatment, the ESDM+VitD3 group had a significant increase in the level of 25(OH)D and significant reductions in the total score and the scores on self-care, sensation, social interaction and language subscales of the ABC scale (P<0.05), as well as a significant reduction in the total score of the CARS (P<0.05). The ESDM group had a significantly greater reduction in the score on social interaction subscale than the conventional rehabilitation group (P<0.05). The ESDM+VitD3 group had a significantly greater reduction in the score on social interaction subscale than the other two groups (P<0.05). CONCLUSIONS: ESDM can effectively improve the clinical symptoms of toddlers with ASD, with a significantly better clinical effect in improving social interaction and somatic movement than conventional rehabilitation. ESDM combined with VitD3 has a significantly better clinical effect in improving social communication skills and may be one of the best strategies for improving the clinical symptoms of toddlers with ASD.

ABSTRACT

PURPOSE: Vitamin D deficiency has been found in children with chronic tic disorders (CTDs). Our previous data showed that serum 25-hydroxyvitamin D [25(OH)D] level in children with CTDs was lower than that of the healthy controls and lower serum 25(OH)D level was associated with increased severity of the tic disorder. Thus, we intend to further verify this phenomenon and examine the effect of vitamin D3 on CTDs. PATIENTS AND METHODS: In total, 120 children with CTDs and 140 normal controls were enrolled in this study, with 36/120 of those in the CTD group receiving vitamin D3 treatment for 3 months. The Yale Global Tic Severity Scale (YGTSS) and Clinical Global Impression of Severity of Illness (CGI-SI) were, respectively, used to evaluate the tic severity. High-performance liquid chromatography and tandem mass spectrometry were used to measure serum 25(OH)D level. RESULTS: Those children with CTDs exhibited significantly lower 25(OH)D levels than did healthy controls, and these reduced 25(OH)D levels were linked to increasing severity of tic symptoms. After treatment with supplemental vitamin D3, serum 25(OH)D level and scores of YGTSS total, motor tics, phonic tics, total tic, impairment, and CGI-SI improved significantly in children with CTDs without any adverse reactions. CONCLUSION: Supplementation vitamin D3, given its low cost and excellent safety, may be an effective means of improving symptoms in certain children with CTDs.

ABSTRACT

To examine the effects of Cerebrolysin on the treatment of diabetic peripheral neuropathy, we first established a mouse model of type 2 diabetes mellitus by administering a high-glucose, high-fat diet and a single intraperitoneal injection of streptozotocin. Mice defined as diabetic in this model were then treated with 1.80, 5.39 or 8.98 mL/kg of Cerebrolysin via intraperitoneal injections for 10 consecutive days. Our results demonstrated that the number, diameter and area of myelinated nerve fibers increased in the sciatic nerves of these mice after administration of Cerebrolysin. The results of several behavioral tests showed that Cerebrolysin dose-dependently increased the slope angle in the inclined plane test (indicating an improved ability to maintain body position), prolonged tail-flick latency and foot-licking time (indicating enhanced sensitivity to thermal and chemical pain, respectively, and reduced pain thresholds), and increased an index of sciatic nerve function in diabetic mice compared with those behavioral results in untreated diabetic mice. Taken together, the anatomical and functional results suggest that Cerebrolysin ameliorated peripheral neuropathy in a mouse model of type 2 diabetes mellitus.

ABSTRACT

AIMS: This study aimed to assess the differential expression of specific B cell subtypes in patients with chronic viral hepatitis. METHODS: The frequencies of differential expression of specific B cell subtypes in patients with chronic viral hepatitis and healthy controls were assessed by flow cytometry using monoclonal antibodies specific for CD38, CD27, CD86, CD95, TLR-9, and IgD. The effect of adefovir treatment on B cell subsets in HBV patients was determined. The values of clinical parameters in the patients were also measured. RESULTS: The frequency of CD86+ B cells was not significantly different in chronic HBV patients but was higher in HCV patients compared with that in healthy controls. CD95 and IgD levels were lower in HBV and HCV patients than in healthy controls. A significant negative correlation occurred between the proportion of CD95+ B cells and HBV DNA viral load. The frequency of TLR-9 on the B cells in HBV and HCV patients was higher compared with that of healthy controls. After treatment with adefovir, the frequency of CD95 and IgD expressed on B cells was increased in HBV patients. CONCLUSIONS: Activated B cells and exhausted B cells homeostasis were commonly disturbed in HBV and HCV patients.

ABSTRACT

This study aimed to investigate the potential effect of interleukin 33 (IL-33) on humoral responses to hepatitis B virus (HBV) and the possible mechanisms underlying the action of IL-33 in regulating follicular helper T (TFH) cells. The impact of IL-33 treatment on the levels of serum HBV DNA, HBsAg, HBeAg, HBsAb, and HBeAb, as well as the frequencies of CD4(+)CXCR5(+) TFH cells in wild-type HBV transgenic (HBV-Tg) mice and in a transwell coculture of HepG2.2.15 with IL-33-treated peripheral blood mononuclear cells (PBMCs) were determined. Furthermore, the gene transcription profiles in IL-33-treated TFH cells were determined by microarrays. IL-33 treatment significantly reduced the levels of serum HBV DNA, HBsAg, and HBeAg, but increased the levels of HBsAb and HBeAb in HBV-Tg mice, accompanied by increased frequency of splenic infiltrating CD4(+)CXCR5(+) TFH cells in HBV-Tg. Similarly, coculture of HepG2.2.15 cells with IL-33-treated PBMCs reduced the levels of HBV DNA, HBsAg, and HBeAg, but increased the levels of HBsAb and HBeAb. Microarray analyses indicated that IL-33 significantly modulated the transcription of many genes involved in regulating TFH activation and differentiation. Our findings suggest that IL-33 may activate TFH cells, promoting humoral responses to HBV during the pathogenic process.

ABSTRACT

OBJECTIVE: To examine serum 25-hydroxyvitamin D levels in children with autism spectrum disorders (ASD) and to explore the relationship between vitamin D level and ASD. METHODS: Serum levels of 25-hydroxyvitamin D levels were determined by the HPLC-MS/MS method in 117 children with newly diagnosed ASD and 109 healthy controls. Vitamin D status were classified into normal (>30 ng/mL), insufficiency (10-30ng/mL) and deficiency (<10 ng/mL) according to 25-hydroxyvitamin D levels. RESULTS: Serum level of 25-hydroxyvitamin D (19±9 ng/mL)in children with ASD was significantly lower than that in healthy controls (36±13 ng/mL; P<0.01). The rate of vitamin D insufficiency plus deficiency in the ASD group was significantly higher than in the control group (89.7% vs 52.3%; P<0.01). CONCLUSIONS: Vitamin D insufficiency or deficiency is common in children with ASD and might be as one of the environmental or genetic factors for ASD.

ABSTRACT

OBJECTIVE: To study the therapeutic effects of infra-low-frequency transcranial magnetic stimulation in children with spastic cerebral palsy. METHODS: Seventy-five children with spastic cerebral palsy were randomly divided into two groups: control (n=33) and treatment groups (n=42). The treatment group accepted infra-low-frequency transcranial magnetic stimulation besides conventional comprehensive rehabilitation therapy. The control group only accepted conventional comprehensive rehabilitation therapy. Motor functions were assessed by gross motor function measure (GMFM) and fine motor function measure (FMFM) at one and three months after treatment. RESULTS: Improvement in the ability to sit in the treatment was better than in the control group at one month after treatment (P<0.05). Improvement in the ability to sit, crawl and kneel, total score of GMFM, and improvement of joint active ability of limbs, grasping ability and operating ability in the treatment group were better than the control group at three months after treatment (P<0.05). CONCLUSIONS: Infra-low-frequency transcranial magnetic stimulation can effectively improve motor function in children with spastic cerebral palsy.
