Effects of physical fitness training on social adaptive behavior of children with global developmental delay / 中国儿童保健杂志

【Objective】 To explore the effect of physical fitness training on social adaptive behavior of children with global developmental delay (GDD), in order to provide treatment experience for GDD children. 【Methods】 From November 2021 to December 2022, a total of 60 children with GDD diagnosed and treated in the Third Affiliated Hospital of Jiamusi University were enrolled in this study, and were randomly divided into control group (n=30) and test group (n=30).The control group received routine rehabilitation treatment, and the test group received physical fitness training additionally.The intervention lasted for 12 weeks, with the frequency of 3times/week, 30min/time.All subjects were tested for physical fitness and children′s social adaptive behavior before and after training. 【Results】 Before treatment, the difference between the results of physical fitness test and social adaptive behavior scores of the GDD children in two groups was not statistically significant (P>0.05).After 3 months of treatment, the physical fitness test scores, except body mass index (BMI), and social adaptive behavior scores of the GDD children in two groups were significantly different from those before treatment (P<0.05), and the physical fitness test scores (except for height, weight and BMI) and the social adaptive behavior of the test group were better than those of the control group (t=2.363,4.020,3.331,3.338,P<0.05). 【Conclusion】 Physical fitness training can significantly improve the adaptive behavior, independent function, cognitive function and social/self-control ability of GDD children.

A study of health fitness levels and influence factors of preschool children with autism spectrum disor-ders / 中国康复医学杂志

Objective:To investigate the level of healthy fitness in preschool children with autism spectrum disorder(ASD),to explore the factors influencing healthy fitness in children with ASD,and to provide reference for their comprehensive rehabilitation treatment and home exercise guidance. Method:Fifty children in the ASD group and 50 children in the normal group were selected to test the health fitness level using seven indexes:body mass index,20m round-trip run,tennis long throw,standing long jump,isometric push-up,one-legged stance,and seated forward bend.The differences in health fitness levels between preschool children with ASD and normal children were analyzed using independent samples t-test,and the effects of gender,BMI,average daily sleep time,average daily sedentary time,average daily TPA time,average daily MVPA time,mother's education level,father's education level,family income,and age of child's primary caregiver on health fitness of preschool children with ASD were analyzed using multiple linear regression models. Result:Comparative analysis between groups showed that the ASD group had a much lower tennis ball toss than the normal group(P＜0.05),and significantly lower scores in the 20-meter round-trip run,isometric push-ups and one-leg stand test than the normal group(P＜0.001),while the differences in body mass index,stand-ing long jump and seated forward bend scores were not statistically significant(P＞0.05).Multiple linear regres-sion model analysis showed that the mean daily sleep,Total Physical Activity(TPA),and Moderate to Vigor-ous Intensity Physical Activity(MVPA)time had a good fit for the 20 m round-trip run(20 m round-trip run=-9.561+1.048 x average daily sleep time+0.076 x average daily TPA time+0.066 × average daily MVPA time);average daily TPA time was well fitted for the isometric push-ups(isometric push-ups=-87.625+0.428x average daily TPA time);average daily TPA and MVPA times were well fitted for the single-leg stand(aver-age duration of single-leg stand=6.627+0.094 x average daily total physical activity time+0.071 x average daily moderate-to-vigorous activity time). Conclusion:The cardiopulmonary fitness,motor fitness and upper limb muscle fitness of preschool children with ASD are lower than those of normal children,and physical fitness training should be included in the comprehensive rehabilitation intervention program.The longer sleep time,the longer TPA time and the longer MVPA time may suggest the better cardiorespiratory fitness and motor fitness of preschool children with ASD,and the effective duration of sleep time and moderate-to-vigorous physical activity of preschool children with ASD should be enhanced.

ObjectiveTo develop a rehabilitation program of nature posture treatment (NPT) suspension therapy based on the International Classification of Functioning, Disability and Health-Children and Youth version (ICF-CY) framework, and apply it to neurodevelopmental disorders. MethodsThe ICF-CY theoretical group (group A) and NPT suspension therapy group (group B) were established. Group A searched literature from common databases, to extract high-frequency words related to suspension therapy and match with categories of ICF-CY, to develop ICF-CY theoretical framework of the NPT suspension therapy. Group B developed specific rehabilitation procedures and training items based on the framework to compose the training pool. A total of 110 children aged less than six years with neurodevelopmental disorders and associated motor impairments were selected from outpatient or inpatient of the First Affiliated Hospital of Xinxiang Medical University, between October, 2019 and October, 2022. They were randomly divided into control group (n = 55) and clinical group (n = 55), who received routine neurodevelopmental therapy and NPT suspension therapy program based on ICF-CY, respectively, for a week. The incidence of satisfaction, acceptance and adverse events were observed. ResultsTwo cases in the control group and four cases in the clinical group dropped down. For the clinical group, the incidence of satisfaction was 98% (50/51), with acceptance of 96% (49/51), and one adverse event occurred. For the control group, the incidence of both the satisfaction and acceptance was 100%, and no adverse event occurred. There was no significant difference in the incidence of satisfaction, acceptance and the adverse event (P > 0.05). ConclusionThe NPT suspension therapy program based on the ICF-CY framework is safe and acceptable for children with neurodevelopmental disorders.

Risk factors for neonatal asphyxia and establishment of a nomogram model for predicting neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture: a multicenter study / 中国当代儿科杂志

OBJECTIVES@#To investigate the risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture and establish a nomogram model for predicting the risk of neonatal asphyxia.@*METHODS@#A retrospective study was conducted with 613 cases of neonatal asphyxia treated in 20 cooperative hospitals in Enshi Tujia and Miao Autonomous Prefecture from January to December 2019 as the asphyxia group, and 988 randomly selected non-asphyxia neonates born and admitted to the neonatology department of these hospitals during the same period as the control group. Univariate and multivariate analyses were used to identify risk factors for neonatal asphyxia. R software (4.2.2) was used to establish a nomogram model. Receiver operator characteristic curve, calibration curve, and decision curve analysis were used to assess the discrimination, calibration, and clinical usefulness of the model for predicting the risk of neonatal asphyxia, respectively.@*RESULTS@#Multivariate logistic regression analysis showed that minority (Tujia), male sex, premature birth, congenital malformations, abnormal fetal position, intrauterine distress, maternal occupation as a farmer, education level below high school, fewer than 9 prenatal check-ups, threatened abortion, abnormal umbilical cord, abnormal amniotic fluid, placenta previa, abruptio placentae, emergency caesarean section, and assisted delivery were independent risk factors for neonatal asphyxia (P<0.05). The area under the curve of the model for predicting the risk of neonatal asphyxia based on these risk factors was 0.748 (95%CI: 0.723-0.772). The calibration curve indicated high accuracy of the model for predicting the risk of neonatal asphyxia. The decision curve analysis showed that the model could provide a higher net benefit for neonates at risk of asphyxia.@*CONCLUSIONS@#The risk factors for neonatal asphyxia in Hubei Enshi Tujia and Miao Autonomous Prefecture are multifactorial, and the nomogram model based on these factors has good value in predicting the risk of neonatal asphyxia, which can help clinicians identify neonates at high risk of asphyxia early, and reduce the incidence of neonatal asphyxia.

Prevalence, risk factors and parental perceptions of gastroesophageal reflux disease in Asian infants in Singapore

INTRODUCTION@#Infant gastroesophageal reflux disease (GERD) is a significant cause of concern to parents. This study seeks to describe GERD prevalence in infants, evaluate possible risk factors and assess common beliefs influencing management of GERD among Asian parents.@*METHODS@#Mother-infant dyads in the Singapore PREconception Study of long-Term maternal and child Outcomes (S-PRESTO) cohort were prospectively followed from preconception to 12 months post-delivery. GERD diagnosis was ascertained through the revised Infant Gastroesophageal Reflux Questionnaire (I-GERQ-R) administered at 4 time points during infancy. Data on parental perceptions and lifestyle modifications were also collected.@*RESULTS@#The prevalence of infant GERD peaked at 26.5% at age 6 weeks, decreasing to 1.1% by 12 months. Infants exclusively breastfed at 3 weeks of life had reduced odds of GERD by 1 year (adjusted odds ratio 0.43, 95% confidence interval 0.19-0.97, P=0.04). Elimination of "cold or heaty food" and "gas producing" vegetables, massaging the infant's abdomen and application of medicated oil to the infant's abdomen were quoted as major lifestyle modifications in response to GERD symptoms.@*CONCLUSION@#Prevalence of GERD in infants is highest in the first 3 months of life, and the majority outgrow it by 1 year of age. Infants exclusively breastfed at 3 weeks had reduced odds of GERD. Cultural-based changes such as elimination of "heaty or cold" food influence parental perceptions in GERD, which are unique to the Asian population. Understanding the cultural basis for parental perceptions and health-seeking behaviours is crucial in tailoring patient education appropriately for optimal management of infant GERD.

Advance in Neural Control in Eccentric Exercise (review) / 中国康复理论与实践

The nervous system controls eccentric exercise in a special way. During eccentric exercise, excitability increases in cortex, and inhibition decreases, causing excitability decrease in spinal cords. In another hand, increased cortical excitability results in extra excitatory compensation for spinal inhibition. The excitability of the corticospinal pathway depends on the balance between excitability and inhibition of the spinal cord level finally, which usually decreases. Many factors, such as the intensity of contraction, can affect the balance of corticospinal excitability. There is a cross-over effect in eccentric exercise, which promotes corticospinal excitability in untrained limbs. However, the effects and mechanisms of muscle length, fatigue and training duration are still unclear, and current researches have focused in the healthy populations. More researches are needed to explore the effects of eccentric exercise on ill populations.

A clinical epidemiological investigation of neonatal acute respiratory distress syndrome in southwest Hubei, China / 中国当代儿科杂志

OBJECTIVE@#To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China.@*METHODS@#According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017.@*RESULTS@#A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66).@*CONCLUSIONS@#Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

Analysis on Gene Set Enrichment of Related Signaling Pathways and Immune Infiltration in Intracranial Aneurysm / 中国实验方剂学杂志

Objective::Based on gene array technology, gene set enrichment analysis (GSEA) and immune infiltration analysis were performed on chip data of intracranial aneurysm (IA) mRNA expression profile, in order to provide theoretical basis for understanding the formation mechanism of IA. Method::The GSE75436 raw data were obtained from the gene expression omnibus (GEO). GSEA of biological process (BP) in gene ontology (GO) and Kyoto gene and genome encyclopedia (KEGG) signaling pathways were analyzed for gene expression profile by R software. The CIBERSORT deconvolution method was used to analyze the infiltration ratio of 22 types of immune cells in the expression profile. And COREMINE database was used to predict traditional Chinese medicines (TCMs), which were significant correlation with the enrichment result. Result::The GSEA results showed that the changes in gene expression of IA samples mainly involved in the regulation of cytokines, activation and differentiation of leukocyte, inflammatory immune response and other processes. The infiltration matrix analysis of immune cells showed that mast cells resting and neutrophils were significantly reduced in IA samples. The comparison of paired samples showed that mast cells and natural killer cells (NK cells) were significantly activated in the IA samples of the same individual, while neutrophils and T cells CD4 naive were significantly reduced. Through COREMINE prediction, it was found that Stephaniae Tetrandrae Radix was correlated with the activation of granulocytes, Sapindi Mukorossi Semen and Pistaciae Chinensis Cortex were correlated with the activation of neutrophils, Trichosanthis Semen, Paeoniae Radix Alba and Ligustri Lucidi Fructus were correlated with the cytotoxicity mediated by NK cells. Conclusion::Activation of mast cells and NK cells are closely associated with the occurrence and development of IA. The inflammatory immune processes and pathways such as nucleotide-binding oligomerization domain (NOD)-like receptor (NLR) signaling pathway and cytotoxicity mediated by NK cells may be important factors in the pathogenesis of IA, and TCMs such as Stephaniae Tetrandrae Radix may be the potential molecular drug sources.
