Objective: To explore the association between executive function and emotional and behavioral problems in first-grade elementary school students, so as to provide a reference for promoting children s mental health. Methods: From March to May 2024, 423 first-grade elementary school students from 6 primary schools aged 6-7 were selected by using stratified cluster random sampling in Shanxi, Shanghai, Shandong, Guangxi, Xinjiang, and Jiangxi. Data were collected by using the Executive Function Assessment Scale and the Strengths and Difficulties Questionnaire. An independent samples t-test was used to analyze differences in executive function of different genders and differences in emotional and behavioral problems among first-grade school students with varying executive function levels; a linear regression model was employed to analyze the association between children s executive function and emotional and behavioral problems. Results: A total of 42 first-grade elementary school students (9.9%) were identified as having executive function deficits. Students in the executive function deficit group scored higher on internalizing behavior (7.50±0.52), externalizing behavior (11.26±0.52), and total difficulties (18.52± 0.93 ) were significantly higher than those of children without deficits (4.37±0.14, 6.69±0.17, 10.64±0.27) ( t =5.79, 8.50, 9.23, all P <0.05). Results of linear regression analysis showed that, after controlling for relevant covariates such as gender, age, family economic status, being an only child, and body mass index, the factor scores, dimensional scores, and total scores of executive function were all positively correlated with scores for externalizing problems, internalizing problems, and total difficulties ( β =0.07-0.32, all P <0.05). Conclusions Children s executive function is closely associated with emotional and behavioral problems, and those with poorer executive function exhibit more pronounced emotional and behavioral problems. Improving children s executive function may help promote their mental health.

BACKGROUND:Liuwei Dihuang Wan takes"three tonifying and three reducing effects"as its compatibility feature to nourish yin and tonify the kidneys,while Zuogui Wan takes"seeking yin in yang"as its compatibility feature to nourish yin and tonify the kidneys by promoting yang.Both of them belong to the same method of nourishing yin and tonifying the kidneys,and have better curative effects at the symptomatic and cellular molecular levels. OBJECTIVE:To observe the effects of Liuwei Dihuang Wan and Zuogui Wan in bone metabolism,and to explore their mechanism of action in the osteoprotegerin(OPG)/receptor activator of nuclear factor-κB ligand(RANKL)osteoblastic pathway. METHODS:Thirty-two Sprague-Dawley rats were randomized into model,Liuwei Dihuang Wan,Zuogui Wan,and sham operation group,with eight rats in each group.Osteoporosis models were prepared using removal of both ovaries in the first three groups.Starting at 30 days postoperatively,rats in the Liuwei Dihuang Wan group were gavaged with Liuwei Dihuang Wan 1.125 g/kg/d;rats in the Zuoqui Wan group were gavaged with Zuogui Wan 2.25 g/kg/d;and rats in the sham operation group and the model group were gavaged with saline 10 mL/kg/d.After 12 weeks of gavage,the rat tibia was taken to measure bone mineral density.The serum levels of estrogen,bone alkaline phosphatase,and cAMP/cGMP were measured using ELISA,and the expression of OPG/RANKL in the femur was detected using western blot. RESULTS AND CONCLUSION:Compared with the sham operation group,the model group showed a decrease in bone mineral density and levels of estrogen and bone alkaline phosphatase(P＜0.05)and an increase in cAMP/cGMP level(P＜0.05).Compared with the model group,the Liuwei Dihuang Wan group and the Zuogui Wan group significantly increased bone mineral density(P＜0.05)and bone alkaline phosphatase levels(P＜0.05);the Zuogui Wan group significantly decreased cAMP/cGMP levels(P＜0.05)and upregulated OPG expression(P＜0.05);the Liuwei Dihuang Wan group upregulated OPG expression and downregulated RANKL expression(P＜0.05);and both groups were unable to significantly increase estrogen levels(P＞0.05).To conclude,Zuogui Wan,which seeks yin from yang,can effectively increase the expression of OPG but cannot downregulate the expression of RANKL.However,Liuwei Dihuang Wan,which has three tonifying and three reducing effects,can bidirectionally regulate the expression of OPG and RANKL.This result suggests that Liuwei Dihuang Wan can significantly inhibit osteoclastic function compared with Zuogui Wan,and further research is needed to verify this conclusion.

Objective To screen the mutations of ABCC8 gene in probands of maturity-onset diabetes of the young pedigrees,and investigate it sgenetic and clinical characteristics.Methods Whole exome sequencing were performed to screen ABCC8 mutations in 56 MODY probands who were admitted to Department of Endocrinology and Metabolism,Shanghai Sixth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from July 2021 to December 2023.The mutations were verified by Sanger sequencing,and all participants were genotyped.Clinical phenotypes of the mutation carriers were compared with non-DM controls within the families.The identified mutations were evaluated by bioinformatic softwires.Then the pharmacogenomic characteristics of the mutation carriers were analyzed.Results Two heterozygous mutations D655V and R825Q were identified in two MODY probands and their families respectively,and the D655V was a novel mutation.Bioinformatics studies showed that both mutations were deleterious and pathogenic.In comparison with non-DM controls in the two families,mutation carriers with diabetes exhibited significantly lower fasting insulin/fasting plasma glucose,two-hour postprandial insulin/two-hour postprandial insulin plasma glucose,homeostatic model assessment-β(P<0.05).Treatment with oral hypoglycemic agents such as metformin or insulin in these mutation carriers resulted in a moderate reduction in plasma glucose levels.However,switching to targeted Sulfonylurea's(SUs)proved to be more effective.Conclusions In this study,the prevalence of MODY12 is 3.6%in these MODY pedigrees.The remarkable hypoglycemic efficacy of SUs suggests that both D655V and R825Q were activating mutations of ABCC8,and maybe the cause of MODY12 characterized by impaired insulin secretion.

OBJECTIVE: To investigate the clinical and genetic characteristics of a family with Vissers-Bodmer Syndrome (VIBOS) and to review the relevant literature on VIBOS caused by CNOT1 gene variants. METHODS: A child diagnosed with VIBOS due to "growth retardation for over 6 years" at the Linyi People's Hospital on March 1, 2024 and her family members were selected as the study subjects. Clinical data of the family were collected. Peripheral venous blood samples were collected from the family members. Whole-exome sequencing (WES) was performed on the proband's peripheral blood, and Sanger sequencing was used for verification of the candidate variant in the family. Pathogenicity of the candidate variant was classified according to the "Standards and Guidelines for the Interpretation of Sequence Variants" established by the American College of Medical Genetics and Genomics American College of Medical Genetics (ACMG). Bioinformatics analysis, including pathogenicity prediction using Mutation Taster, three-dimensional protein structure modeling using SWISS-MODEL, and functional impact assessment using PyMOL, was performed. Relevant literature on VIBOS patients due to variants of the CNOT1 gene was retrieved from databases such as CNKI, Wanfang Data, and PubMed. The clinical phenotypes and genotypes of the patients were summarized. This study was approved by the Medical Ethics Committee of the Hospital (Ethics No.: YX200303). RESULTS: The proband, a 6-year-and-7-month-old female, presented with short stature, distinctive facial features (esotropia, hypertelorism, prominent nasolabial folds), webbed neck, clinodactyly, and intellectual disability. WES revealed that she has carried a heterozygous c.736delG (p.V246*) variant of the CNOT1 gene, which was unreported previously. The proband's father exhibited borderline intellectual function but no short stature or distinctive facial features. Sanger sequencing confirmed that he has carried the same heterozygous variant. According to the ACMG guidelines, this genetic variant was predicted as "likely pathogenic" (PVS1+PM2_Supporting). The c.736delG (p.V246*) variant was predicted to have a deleterious effect by Mutation Taster. Subsequent homology modeling using SWISS-MODEL, coupled with structural visualization and comparison using PyMOL, confirmed that it may cause premature termination of translation and produce a truncated protein. Literature search has retrieved five articles on VIBOS due to CNOT1 gene variants, which included 45 cases. Together with the proband and her father, the common clinical features among these 47 patients included distinctive facial features (83.0%, 39/47), speech delay (70.2%, 33/47), motor delay (70.2%, 33/47), intellectual disability (59.6%, 28/47), and short stature (48.9%, 23/47). In terms of the types of the variants, missense variants were the most common (47.4%, 18/38), followed by frameshift variants (21.0%, 8/38). The variant sites have mainly located in exons 7, 25, and 31. No significant genotype-phenotype correlation was noted. CONCLUSION The c.736delG (p.V246*) frameshift variant of the CNOT1 gene is likely the genetic etiology of VIBOS in this proband. The clinical manifestations of the proband were more severe than in her fathers, which suggested phenotypic variability associated with this variant. This study has provided new evidence for the understanding of the genetic basis of VIBOS.

Objective:To characterize the clinical and genetic features of 2 patients with interleukin-1 receptor associated kinase (IRAK) 4 deficiency and to assess the pathogenicity of their genetic variants.Methods:This case series included two patients diagnosed with IRAK4 gene deficiency at Shenzhen Children′s Hospital and the University of Hong Kong-Shenzhen Hospital between 2019 and 2024. Six healthy children without recent infections or immunodeficiency served as controls. Peripheral blood mononuclear cells were stimulated in vitro with Toll-like receptor 4 (TLR4) agonists, and cytokine levels were quantified using a protein chip assay.Results:The 2 patients, a 5-year-old boy and a 10-year-old girl, presented with recurrent invasive or non-invasive bacterial infections and impaired acute-phase inflammatory responses. Genetic testing identified a homozygous frameshift variant (c.540delT, p.F180Lfs*26) in Patient 1 and compound heterozygous frameshift variants (c.166delT, p.F56fs and c.629delG, p.R210fs) in Patient 2, all predicted to result in truncated IRAK4 proteins. Both patients received regular infection prophylaxis with favorable clinical outcomes. Controls consists of 3 males and 3 females, aged 5-17 years. Following TLR4 stimulation, cytokine levels in Patient 1, Patient 2, and controls (tumor necrosis factor-α 68.6, 103.0, 618.7 (392.7, 824.1); interleukin (IL)-1β 39.8, 10.8, 1 975.5 (1 556.0, 2 096.5); interferon-γ 8.6, 6.2, 13.5 (12.7, 14.9); granulocyte colony-stimulating factor 17.6, 15.9, 2 890.0 (1 622.0, 4 692.8); IL-6 140.1, 352.7, 7 222.5 (5 768.5, 8 043.5); and IL-17 47.5, 44.5, 59.7 (43.4, 69.5), respectively.Conclusions:IRAK4 deficiency should be suspected in patients with early-onset recurrent bacterial infections and attenuated inflammatory response. Homozygous and compound heterozygous frameshift variants in IRAK4 gene lead to truncated IRAK4 proteins and impared innate immune signaling.

Objective To explore the effectiveness of building block assembly games in the upper limb functional exercise of school-aged children with peripherally inserted central catheter catheterization.Methods Using convenience sampling,90 catheterized children who met the inclusion criteria in the pediatric ward of a tertiary hospital in Henan Province from November 2022 to April 2023 were selected as research subjects.They were randomly divided into an experimental group and a control group,with 45 cases in each group.The experimental group participated in building block assembly games in addition to conventional ball-gripping exercises,while the control group engaged solely in conventional ball-gripping exercises.The compliance rates of upper limb exercises,time average peak flow rate of axillary vein of the catheterization side,and the incidence of catheter-related complications were compared between the 2 groups.Results During the study,2 cases in the experimental group and 3 in the control group dropped out,resulting in 43 cases in the experimental group and 42 in the control group.The compliance rate of upper limb exercises in the experimental group during hospitalization was 93.03％,significantly higher than 64.29％in the control group(P＜0.001).On the third day after catheterization,the time average peak flow rate of axillary vein of the catheterization side was(5.58±1.24)cm/s and(5.37±1.24)cm/s on the seventh day in the experimental group,compared to(3.87±1.06)cm/s and(3.56±0.81)cm/s,respectively,in the control group.These differences were statistically significant(P＜0.001).The incidence of catheter-related thrombosis in the experimental group was 4.65％,significantly lower than 21.43％in the control group(P=0.021).The rates of bleeding at the puncture site and catheter displacement in the experimental group were both 4.65％,compared to 7.14％and 4.76％,respectively,in the control group.These differences were not statistically significant(both P＞0.05).Conclusion Incorporating building block assembly games into routine ball-gripping exercises can improve the compliance of upper limb exercises in children with PICC placement,improve the blood flow velocity in the axillary vein of the catheterization upper limb,and reduce the incidence of catheter-related thrombosis,without increasing the risk of bleeding at the puncture site or catheter displacement.

Objective:To investigate the clinical efficacy and safety of pulmonary rehabilitation in elderly patients with chronic obstructive pulmonary disease(COPD)who are undergoing long-term home oxygen therapy.Methods:The study included a total of 60 elderly patients with COPD who were successfully discharged after receiving treatment at the First Hospital of Shanxi Medical University from November 2021 to October 2022.The enrolled patients were randomly divided into two groups: the pulmonary rehabilitation group and the control group, with 30 patients in each group.The allocation was determined using a random number table and prospective research methods.Patients in the pulmonary rehabilitation group underwent a 12-week pulmonary rehabilitation training program, while patients in the control group received pulmonary rehabilitation education and nutrition education.The general data of the two groups of patients were compared, including lung function parameters[forced expiratory volume in one second(FEV 1), forced vital capacity(FVC), forced expiratory volume in one second to forced vital capacity ratio(FEV 1/FVC), and percentage of predicted forced expiratory volume in one second(FEV 1%pred)], blood gas analysis[partial pressure of arterial oxygen(PaO 2), partial pressure of arterial carbon dioxide(PaCO 2), arterial oxygen saturation(SaO 2)], 6-minute walking distance(6MWD), grip strength, 5-round sit to stand test(5R-STST), modified British medical research council(mMRC)score, COPD assessment test(CAT)score, closed cycles test(CCT), Berg balance scale(BBS), and safety measures.These parameters were assessed before and after the intervention. Results:A total of 29 patients in the pulmonary rehabilitation group and 28 patients in the control group completed the study.The general data between the two groups showed no significant difference(all P>0.05).After the intervention, patients in the pulmonary rehabilitation group showed improvements in FEV 1/FVC, PaO 2, PaCO 2, SaO 2, 6MWD, grip strength, 5R-STST, CAT, CCT, and BBS( t=-2.242, -4.630, W=-3.439, t=-6.512, -10.563, -6.197, W=-3.968, t=10.847, -7.334, W=-4.189, all P<0.05).Additionally, 6MWD, CAT, and CCT showed significant improvement after the intervention compared to the control group( t=-2.104, 2.183, 2.106, all P<0.05).No training-related adverse effects were observed during the study. Conclusions:The 12-week pulmonary rehabilitation program is shown to be effective for elderly patients with COPD who are undergoing long-term home oxygen therapy.This program helps to improve respiratory function, systemic symptoms, exercise endurance, muscle strength, and balance function.It is designed to be simple and easy to implement, allowing patients to achieve their training goals and improve their clinical symptoms.Additionally, the program has been found to be safe and well-tolerated by patients, making it a valuable intervention that should be promoted and widely applied.

Objective To identify epidemiological characteristics and pathogen distribution of hand,foot,and mouth disease(HFMD)in Hebei Children's Hospital in order to support prevention and treatment of HFMD.Methods A total of 1 698 cases throat swab samples from children diagnosed as HFMD from 2016 to 2023 were collected.Real-time PCR was used to detect the specific classification of HFMD.Statistical analysis was performed according to the year,season,age,and sex and enterovirus type of HFMD in the children.Results From 2016 to 2023,the ratio of male to female patients among the 1 698 children admitted to Hebei Children's Hospital was 1.72∶1.Among them,the highest incidence rate in summer was 778 cases,accounting for 45.8%of all cases,followed by autumn,with a total of 614 cases,accounting for 36.2%of cases.The highest incidence was recorded in age group of 1-3 years,with a total of 1 032 cases(60.8%).The lowest incidence was 38 cases in age group＞6 years old(2.2%);There were 988 cases of HFM(58.2%)caused by different strains of enterovirus undefined(EVU)except enterovirus 71(EV71)and coxsackievirus A16(CA16).Conclusions HFMD found in Hebei Children's Hospital from 2016 to 2023 are mainly caused by enteroviruses except EV 71 and coxsackievirus A16.High morbid-ity is found in children aged 1-3 years,and summer and autumn are the main epidemic seasons.This result may facilitate and support decision making and strategy development in disease prevention and control as well as to strengthen public health resources.
