Objective To systematically evaluate the prevalence of depressive symptoms among children and adolescents in China. Methods A comprehensive search was conducted in PubMed, Embase, Cochrane Library, Web of Science, Wanfang Data, China Biomedical Literature Database, China National Knowledge Infrastructure, and VIP Database for literature published from January 2015 to May 2024 regarding the prevalence of depressive symptoms among Chinese children and adolescents. Stata 16.0 software was used for Meta analysis, and Egger's test and funnel plot analysis were performed to assess publication bias. Results A total of 53 studies were included, encompassing 314 867 children and adolescents, with 65 324 exhibiting depressive symptoms, resulting in a prevalence rate of 23.3% (95%CI: 21.4%-25.1%). Subgroup analysis revealed higher prevalence rates among females, those in rural areas, vocational high school students, individuals from the eastern region, those assessed using the Depression Self-Rating Scale for Children, and during the COVID-19 pandemic, with rates of 24.9%, 29.5%, 28.1%, 25.6%, 27.2%, and 27.7%, respectively. The distribution of studies in the funnel plot was roughly symmetrical, but Egger's test indicated potential publication bias (P<0.001). Conclusions The prevalence of depressive symptoms among children and adolescents in China is relatively high, particularly among females, those in rural areas, vocational high school students, and those in the eastern regions. Additionally, the COVID-19 pandemic may have impacted the incidence of depressive symptoms in this population.

It aims to provide a systematic approach to neonatal transport in primary care settings, tailored to the national context of China, offering guidance and decision-making support for primary healthcare providers.

The prevalence of depressive disorder among adolescents is rising, causing serious harm to families and society. Examining risk behaviors such as gaming addiction, non-suicidal self-injury, and suicidal behaviors resulting from adolescent depressive disorder in light of psychosocial and pathophysiological perspectives, along with in-depth exploration of diagnostic and therapeutic dilemmas—including insidious onset, high comorbidity, and difficulties in differential diagnosis—helps build a multidimensional intervention system encompassing psychological, pharmacological, and physical therapies. It also provides a theoretical basis for promoting multicenter cohort studies and establishing a comprehensive prevention and control model linking families, schools, and hospitals. This paper systematically outlines the current epidemiological status, comorbidity spectrum, and clinical pathways for early identification and comprehensive intervention in adolescent depressive disorder.

Objective To analyze the Bayesian network of harsh parenting, experiential avoidance, and adolescent short video addiction risk, identify key nodes, and provide precise recommendations for intervention. Methods In March 2025, the Harsh Parenting Scale, Experiential Avoidance Scale, and Short Video Addiction Scale were administered to 1 594 adolescents. Network analysis was performed using JASP 0.95.4, and key nodes were identified via centrality estimation. Results The core nodes of harsh parenting, experiential avoidance, and short video addiction risk were "I am hit with hands or kicked when I do something wrong or make my parents angry" (expected influence = 0.301), "Certain feelings make me feel scared" (expected influence = 0.684), and "Withdrawal" (expected influence = 1.222), respectively. Conclusions Interventions targeting these key nodes serve as an important reference for mitigating the impact of harsh parenting, experiential avoidance, and short video addiction risk on adolescents.

Pediatric chronic myeloid leukemia (CML) is more aggressive than adult CML, with unique molecular characteristics and a higher propensity for lymphoid blast crisis. The application of tyrosine kinase inhibitors (TKIs) has significantly improved the prognosis of pediatric CML. Based on international consensus and clinical experience, this article proposes standardized diagnosis and treatment recommendations for pediatric CML, covering initial therapy selection, efficacy evaluation, drug switching, and management of adverse effects. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is recommended only for patients with disease progression or failure of multiple lines of TKI therapy. For children newly diagnosed with CML in accelerated phase, high-dose imatinib or second-generation TKIs are recommended as first-line therapy. Those achieving optimal responses should continue maintenance therapy, while non-responders require switching to alternative TKIs and consider allo-HSCT. For blast-phase CML, induction therapy requires a combination of TKIs and chemotherapy, with allo-HSCT serving as the core curative intervention. This article highlights common but challenging problems (poor response, drug intolerance, and disease progression) in pediatric CML treatment using three typical cases, aiming to optimize treatment strategies. Furthermore, the goal of achieving treatment-free remission needs to be further addressed through multi-center clinical studies.

Early screening, diagnosis, and intervention for congenital muscular torticollis (CMT) in infants are crucial for improving clinical outcomes. However, in China, limited awareness of CMT among child healthcare institutions and caregivers, as well as inconsistent professional standards among rehabilitation personnel, pose significant challenges to the effective diagnosis and management of CMT. The "Physical therapy management of congenital muscular torticollis: a 2024 evidence-based clinical practice guideline from the American Physical Therapy Association Academy of Pediatric Physical Therapy" includes 17 action statements, primarily addressing the prevention, identification, assessment, and intervention of CMT. This guideline is expected to facilitate early detection of CMT in infants, enhance the treatment capabilities of physical therapists, and improve clinical outcomes. This article provides an interpretation of the guideline in the context of the current status of CMT diagnosis and management in China, aiming to offer a reference for improving the ability of primary child healthcare providers and physical therapists to recognize and manage CMTropriately.

In order to effectively assist primary healthcare providers in standardizing the screening of congenital heart disease (CHD), enabling early identification of critical CHD in neonates, and ensuring timely referral to reduce the risk of complications and mortality, the Subspecialty Group of Neonatology, Society of Pediatrics,Chinese Medical Association has led a team of experts to integrate the latest clinical research advances on CHD. Following comprehensive discussions, the "Expert consensus on the diagnosis and treatment of common neonatal diseases in primary healthcare institutions: congenital heart disease (2025)" was developed. The consensus covers eight common clinical questions faced by primary healthcare providers regarding CHD and provides 13 recommendations.

Seizures are common clinical emergencies in neonatology, potentially leading to severe complications and directly impacting the neurodevelopmental prognosis of the infants with this condition. For primary healthcare providers, key clinical challenges include standardized emergency management, precise clinical diagnosis and treatment, and accurate assessment of referral indications. To assist primary healthcare providers in the prompt identification and standardized management of neonatal seizures, the Subspecialty Group of Neonatology, Society of Pediatrics, Chinese Medical Association organized a panel of experts to develop the "Guideline for the diagnosis and treatment of common neonatal diseases in primary healthcare institutions: neonatal seizures (2025)", based on the latest clinical evidence and expert consensus. This guideline provides primary healthcare providers with 17 recommendations addressing nine common clinical questions in neonatal seizures.

Ureaplasma urealyticum (UU) is a common pathogen colonizing or infecting the neonatal respiratory tract. It can be vertically transmitted from mother to infant, irrespective of the duration of premature rupture of membranes and the mode of delivery. UU infection is an important factor contributing to preterm birth and low birth weight and is closely associated with adverse outcomes such as bronchopulmonary dysplasia and neurodevelopmental impairment. Given the immaturity of neonatal immune and organ systems, pharmacologic treatment must balance efficacy and safety. Currently, no unified standard regimen has been established for the treatment of neonatal UU infection. This review summarizes pharmacotherapeutic options for neonatal UU infection to inform clinical practice.

Vasovagal syncope (VVS) is the most common cause of neurally mediated syncope in children. Recurrent syncope severely affects physical and mental health and may lead to unintentional injury. Based on international and domestic guidelines and clinical practice experience, standardized recommendations for the diagnosis and treatment of pediatric VVS are proposed. Management of VVS should be individualized, and non-pharmacological interventions, including lifestyle modifications, are the cornerstone for both classic and malignant VVS. Pharmacological therapy is recommended for children with VVS who have recurrent syncopal episodes, are at risk of trauma, or respond poorly to non-pharmacological interventions. For children in whom the head-up tilt test induces asystole, pacemaker implantation is not recommended as first-line therapy. In malignant VVS with recurrent syncope despite conventional treatment, pacemaker implantation may be considered after specialist evaluation. Data on cardioneuroablation in children are limited, and long-term follow-up is required.

This article interprets the "Expert consensus on the management of neonatal parenteral nutrition (2025)", focusing on precise control of parenteral nutrition fluid volume, key considerations for the stability of compounded nutrient solutions, scientific determination of amino acid dosing, and rational recommendations for intravenous lipid emulsion.

Objective To study the clinical characteristics, efficacy, and prognosis of pediatric Langerhans cell histiocytosis (LCH). Methods A retrospective analysis was conducted on 72 children with newly diagnosed LCH. Results The median age of the 72 children was 5 years (range: 0-14 years), with skull involvement being the most common (56 cases, 77.8%). The BRAF-V600E mutation was not associated with clinical characteristics, efficacy, or prognosis (P>0.05). The 5-year overall survival rate was 91.6%±4.2%, and the 5-year event-free survival (EFS) rate was 67.5%±5.8%. The 6-week chemotherapy response rate and 5-year EFS rate were lower in the risk organ involvement group compared to the no risk organ involvement group (P<0.05). The five-year overall survival rates for the group with multi-system involvement and the group with platelet count ≥450×10⁹/L were respectively lower than those for the single-system involvement group and the group with platelet count <450×10⁹/L (P<0.05). Risk organ involvement is an independent risk factor for 5-year EFS (P<0.05). Conclusions Skull is the most commonly affected site in pediatric LCH. The BRAF-V600E mutation is not related to clinical characteristics, efficacy, or prognosis. Elevated platelet count, risk organ involvement, and multisystem involvement are associated with poor prognosis, with risk organ involvement being an independent risk factor for 5-year EFS.

Duchenne muscular dystrophy (DMD) is an X-linked recessive neuromuscular disorder characterized primarily by progressive degeneration and necrosis of skeletal muscle, resulting from mutations in the Dystrophin gene. Patients with DMD typically present with progressive muscle weakness and atrophy during childhood. Currently, available treatment options for DMD remain limited and their efficacy is suboptimal. This review aims to provide a systematic overview of recent advances in therapeutic strategies for DMD, including an analysis of the mechanisms underlying various treatment approaches, outcomes from clinical trials, and their potential clinical applications, in order to inform and guide clinical decision-making.

Objective To evaluate the clinical utility and translational potential of a remote jaundice monitoring system for home-based screening of neonatal hyperbilirubinemia. Methods A prospective self-controlled study was conducted, enrolling 538 newborns with gestational age ≥35 weeks, birth weight ≥2 000 g, and postnatal age ≤14 days at the Women's Hospital of Nanjing Medical University from March to October 2023. Four screening protocols with different predictive indicators were developed based on the Chinese Neonatal Transcutaneous Hourly Bilirubin Nomogram. The effectiveness of the system was evaluated, and the feasibility of using the remote jaundice monitoring system in actual home settings was analyzed. Results A total of 538 paired transcutaneous bilirubin (TcB) and total serum bilirubin (TSB) measurements showed a strong correlation (r=0.85, P<0.001), with 95.0% (511/538) of samples within the 95% limits of agreement. Using TcB ≥ the 95th percentile as the predictive indicator, the system achieved 100% sensitivity, 46.2% specificity, and an area under the receiver operating characteristic curve of 0.731 (95%CI: 0.682-0.780). This approach could reduce unnecessary hospital visits by 41.4% (221/538). Conclusions The system integrates the QBH-801 transcutaneous bilirubinometer, intelligent early warning, and remote guidance services, establishing a closed-loop "hospital-to-home" management model. It demonstrates high safety and feasibility, with significant clinical translational value.

Mosquito-borne viruses, including dengue virus (DENV), chikungunya virus (CHIKV), and Zika virus (ZIKV), pose major threats to public health in tropical and subtropical regions worldwide. Neonates are particularly vulnerable, and the associated disease burden has drawn increasing attention. Routes of neonatal infection include vertical mother-to-child transmission (transplacental and peripartum) and postnatal mosquito bites. Clinical manifestations are often nonspecific; a proportion of cases may progress to central nervous system infection, hemorrhagic disease, or long-term neurodevelopmental impairment, with serious consequences for survival and quality of life. Although China has issued prevention and control guidelines for adults and pregnant women, systematic clinical guidance tailored to neonates remains lacking. In response, the Perinatal Group of the Pediatric Branch of the Chinese Medical Doctor Association convened a multidisciplinary panel to develop this expert consensus, integrating the latest international evidence with China's practical prevention and control experience. The consensus addresses epidemiology; the effects of maternal infection on fetuses and neonates; clinical manifestations; diagnosis and differential diagnosis; early warning indicators of severe disease; therapeutic strategies and supportive care; and prevention and maternal-infant management. It aims to provide evidence-based, standardized, and practical guidance for frontline clinicians managing neonatal mosquito-borne viral infections.

Objective To study the clinical and imaging features of children with influenza-associated encephalopathy (IAE), and to investigate the influencing factors for prognosis. Methods A retrospective analysis was conducted on the medical data (clinical data, laboratory examinations, imaging data, and prognosis) of 23 children with IAE who were diagnosed and treated in Children's Hospital of Nanjing Medical University from May 2022 to April 2023. Results Among the 23 patients, 18 (78%) had influenza A and 5 (22%) had influenza B. All patients had fever and encephalopathy, and 20 patients (87%) had seizures, while 11 patients (48%) had persistent convulsions. There were 10 patients (43%) with an increase in alanine aminotransferase, 14 (61%) with an increase in aspartate aminotransferase, and 18 (78%) with an increase in lactate dehydrogenase. Abnormal imaging findings were observed in 20 patients (87%), among whom 10 (43%) had acute necrotizing encephalopathy. All 23 patients received peramivir or oseltamivir. Of all patients, 12 (52%) achieved complete recovery, 5 (22%) had varying degrees of neurological dysfunction, and 6 (26%) died. Compared with the good prognosis group, the poor prognosis group had significantly higher levels of alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase (P<0.05). Conclusions Fever and convulsions are the most common symptoms of children with IAE, and acute necrotizing encephalopathy is the most common clinical imaging syndrome. Increases in alanine aminotransferase, aspartate aminotransferase, and lactate dehydrogenase have a certain value in predicting poor prognosis.

Objective To investigate the potential circular RNA (circRNA)-microRNA (miRNA)-messenger RNA (mRNA) immune regulatory network in childhood allergic asthma by analyzing microarray datasets. Methods GEO database was used to obtain the datasets of circRNA, miRNA, and mRNA from children with allergic asthma and healthy controls. The Limma package was used to identify differentially expressed circRNA (DEcircRNA), miRNA (DEmiRNA), and mRNA (DEmRNA). ENCORI and other tools were used to predict and construct the regulatory network of endogenous RNA. The DAVID database was used to perform GO and KEGG enrichment analyses, and CIBERSORT and Pearson were used to identify genes associated with immune cell infiltration. Results A total of 130 DEcircRNAs, 40 DEmiRNAs, and 802 DEmRNAs were identified between the asthma and control groups, and a regulatory network consisting of 12 circRNAs, 7 miRNAs, and 75 mRNAs was established. The GO analysis showed that the differentially expressed genes were mainly involved in the regulation of growth and development, and the KEGG analysis showed that they were mainly involved in the mTOR signaling pathway. The CIBERSORT analysis showed that compared with the control group, the asthma group had higher percentages of CD8⁺ T cells and resting NK cells and lower percentages of resting CD4⁺ memory T cells and activated mast cells. In addition, the Pearson correlation analysis identified six key mRNAs that were positively correlated with immune cell infiltration. Conclusions The ceRNA immune regulatory network constructed in this study provides a basis for research on the mechanism of childhood allergic asthma and potential therapeutic targets.

Objective To investigate the readmission rate and risk factors for readmission due to hyperbilirubinemia in neonates with ABO hemolytic disease of the newborn (ABO-HDN), and to construct a risk prediction model for readmission. Methods Neonates diagnosed with hyperbilirubinemia due to ABO-HDN and hospitalized in the neonatal department between January 2021 and December 2023 were enrolled. Based on readmission status, neonates were divided into a readmission group and a control group. Clinical characteristics related to hyperbilirubinemia and risk factors for readmission were analyzed. Subsequently, a prediction model for readmission was constructed, and its predictive performance was evaluated. Results A total of 483 neonates with hyperbilirubinemia due to ABO-HDN were included. The readmission rate was 13.0% (63 cases). Multivariate logistic regression analysis revealed that earlier age at phototherapy initiation, longer duration of phototherapy, occurrence of rebound hyperbilirubinemia, and higher levels of serum total bilirubin and indirect bilirubin at discharge were independent risk factors for hyperbilirubinemia readmission in ABO-HDN neonates (OR=2.373, 4.840, 6.475, 5.033, 1.336 respectively; P<0.05). A risk prediction model for ABO-HDN hyperbilirubinemia readmission was constructed based on these 5 risk factors. Model evaluation demonstrated good predictive performance. Conclusions Age at phototherapy initiation, duration of phototherapy, occurrence of rebound hyperbilirubinemia, and serum total bilirubin and indirect bilirubin levels at discharge are significant influencing factors for readmission due to hyperbilirubinemia in neonates with ABO-HDN. Close monitoring during discharge planning and follow-up management for such neonates is crucial to reduce readmission rates.

In recent years, the incidence rate of pertussis in China has been steadily increasing, presenting an increasingly severe challenge for disease prevention and control. To strengthen the immune barrier in the population and effectively curb the spread of pertussis, National Disease Control and Prevention Administration of China and other relevant authorities optimized the immunization procedure for diphtheria-tetanus-pertussis vaccine, with the new procedure implemented in 2025. This adjustment includes three key measures: advancing the initial dose of the vaccine from 3 months to 2 months of age, extending the interval between primary immunization doses from 1 month to 2 months, and adding an extra dose of acellular diphtheria-tetanus-pertussis vaccine at 6 years of age. This article discusses potential changes in the epidemiology and clinical manifestations of pertussis following such adjustments for immunization procedure, and awareness of these changes will facilitate the accurate identification of pertussis cases, which is crucial for evaluating the impact of these adjustments and further optimizing immunization strategies.

Objective To explore the manifestations of sensory hypersensitivity in children with autism spectrum disorder (ASD) and individuals with subclinical autistic traits. Methods From September 2021 to April 2023, interviews were conducted on 18 college students with high levels of autistic traits and sensory hypersensitivity selected using the Adolescent/Adult Sensory Profile and the Autism Spectrum Quotient (as subclinical group). Interviews were also conducted on the parents of 11 children with ASD aged 6-13 years selected using the intensity sampling method (as clinical group). Qualitative content analysis and thematic analysis were performed on the interview texts to investigate the scenarios and impact of sensory hypersensitivity and coping strategies in the two groups. Results The Autism Spectrum Quotient score was significantly positively correlated with sensory hypersensitivity (r=0.504, P<0.001; n=225). Sensory modalities that triggered sensitive reactions were similar in the subclinical and clinical groups, with auditory hypersensitivity being the most prominent. Sensory hypersensitivity had significant negative impact on emotional wellbeing, cognitive ability, physical health, interpersonal relationships, and general adaptive functioning. These dimensions were interconnected, culminating in a holistic experience. Avoidance was the most commonly used coping mechanism for both groups (16 subclinical participants mentioned it 44 times; 8 clinical participants mentioned it 40 times). The clinical group required more support and help from their caregivers (18 times), while the subclinical group used more proactive coping strategies (e.g., facing sensitive scenarios, distracting attention) to alleviate the negative impact (51 times). Conclusions Sensory hypersensitivity is a common manifestation across the broad ASD phenotype, posing negative effects on multiple aspects of their lives. There is an urgent need for social tolerance and acceptance as well as the development of effective intervention measures.

The prevalence of adolescent depressive symptoms has been rising, and maternal depression is a key predictor. This review synthesizes evidence on mechanisms of influence and on intervention research. The intergenerational transmission of risk from maternal depression appears more pronounced than that associated with paternal depression. At the biological level, genetic susceptibility and neurodevelopmental alterations underpin intergenerational transmission; at the social level, negative parenting practices and stressful family environments create a vicious cycle; at the psychological level, deficits in emotion regulation and insecure attachment amplify vulnerability to depression. Family-based interventions, including cognitive-behavioral therapy and family systems therapy, can mitigate intergenerational transmission. However, more longitudinal research is needed, and future work may integrate digital technologies to develop structured intervention protocols.

With continuous advancements in neonatal care in China, the survival rate of extremely preterm infants has markedly increased in recent years. However, the proportion of voluntary withdrawal of treatment for extremely preterm infants remains relatively high. To further improve the overall treatment success rate for extremely preterm infants in Hunan Province, the Hunan Neonatal Medical Quality Control Center, in collaboration with the Perinatal Committee of the Hunan Medical Association, organized experts to develop recommendations on antenatal counseling for extremely preterm infants. These recommendations aim to standardize antenatal counseling procedures, enhance the scientific rigor and consistency of clinical decision-making, and improve survival outcomes.

Objective To investigate the disease burden of attention-deficit/hyperactivity disorder (ADHD) among children and adolescents in China and to predict future trends, in order to provide evidence for disease control strategies. Methods Based on data from the Global Burden of Disease Study 2021 (GBD 2021), joinpoint regression and prediction models were constructed to analyze and forecast the trends in ADHD burden indicators among Chinese children and adolescents from 1990 to 2021. Results In 2021, the incidence, prevalence, and disability-adjusted life years (DALYs) rates of ADHD among children and adolescents in China increased by 41.46%, 21.44%, and 21.75%, respectively, compared to 1990. From 1990 to 2021, the disease burden of ADHD showed an overall upward trend across sex and age groups, with a heavier burden among males. The highest incidence was observed in children aged 5-9 years, while the highest prevalence and DALY rates were found in those aged 10-14 years. By 2031, the incidence, prevalence, and DALY rates of ADHD among Chinese children and adolescents are projected to reach 324.88 per 100 000, 3 762.36 per 100 000, and 45.85 per 100 000, respectively. Conclusions From 1990 to 2021, the incidence, prevalence, and DALY rates of ADHD among children and adolescents in China have all increased, suggesting that more proactive prevention and intervention measures may be needed to alleviate the disease burden of ADHD in this population.

The "International consensus on early rehabilitation and nutritional management for infants at high risk of neurological impairment" was jointly developed by the Rehabilitation Group of the Pediatrics Branch of the Chinese Medical Association in collaboration with international experts. It aims to provide standardized guidance for early rehabilitation and nutritional management in infants at high risk of neurological impairments. Based on existing evidence and expert opinion, the consensus addresses 10 key clinical questions, including early identification, rehabilitation intervention, and nutritional management, and provides scientific and practical guidance for healthcare professionals in China to improve clinical management and outcomes. This article interprets the consensus to offer relevant guidance for the early rehabilitation and nutritional management of infants at high risk of neurological impairments.

Respiratory syncytial virus (RSV) is one of the main pathogens of acute lower respiratory tract infection in infants and young children and shows a year-round transmission pattern in tropical and subtropical regions, posing a serious health threat, especially to infants under one year of age. Current treatment is mainly symptomatic and supportive, and antiviral drugs have limited efficacy. In recent years, with advances in monoclonal antibody development, the long-acting RSV monoclonal antibody nirsevimab has been introduced into clinical practice worldwide, including in China, and has become a core intervention for immunoprophylaxis in infants and young children. Recommendations are proposed in this consensus based on the latest domestic and international evidence and the epidemiological characteristics of tropical and subtropical regions in China. They cover: epidemiological features of RSV; disease burden and clinical manifestations of RSV infection; dosage and administration of RSV monoclonal antibodies; efficacy and safety of RSV monoclonal antibodies; year-round immunoprophylaxis strategies for infants and young children; immunoprophylaxis strategies for infants and young children with special health conditions; coadministration of RSV monoclonal antibodies with vaccines in the national immunization program; and management measures for immunoprophylaxis with long-acting RSV monoclonal antibodies. The aim is to provide scientific and standardized guidance for frontline clinical and public health practice to reduce the incidence, severity, and public health burden of RSV infection in infants and young children.

Objective To investigate the characteristics and clinical significance of anorectal manometry measurements in children with tethered cord syndrome (TCS) before and after surgery. Methods A retrospective study was conducted on 44 children with TCS treated at the Children's Hospital of Zhejiang University School of Medicine from January 2022 to September 2023. These patients were divided into effective subgroup (n=34) and non-effective subgroup (n=10) based on postoperative symptom improvement. Additionally, 34 children with functional constipation were selected as a control group. Baseline data and manometry measurements were compared between the preoperative TCS group and the control group, as well as between the non-effective and effective subgroups. Results The TCS group had lower short contraction time and defecation relaxation rate compared to the control group (P<0.05), while defecation residual pressure and maximum rectal tolerable threshold were higher than the control group (P<0.05). The length of the anal canal in the high-pressure zone in the effective subgroup was greater postoperatively than preoperatively (P<0.05), and the initial rectal sensation threshold decreased postoperatively (P<0.05). The non-effective subgroup had lower preoperative maximum rectal expulsion pressure compared to the effective subgroup (P<0.05). Postoperative rectal anal inhibition reflex values in the effective subgroup were higher than those in the non-effective subgroup (P<0.05). Conclusions There are some differences in anorectal dynamics between children with TCS and those with functional constipation. Maximum rectal expulsion pressure may be a key predictor of surgical outcomes. Surgery can alter certain defecation functions in some children.

Objective To investigate the distribution of myositis-specific antibodies (MSA) in juvenile dermatomyositis (JDM) and the relationship between MSA and clinical features of JDM. Methods Clinical data of 72 children with JDM hospitalized from January 2020 to April 2025 were reviewed retrospectively, all of whom had been tested for MSA. The relationship between common MSA subtypes and clinical features was analyzed. Results Among the 72 children, 45 (62%) were positive for MSA, including 27 anti-NXP2-positive cases (38%), 10 anti-MDA5-positive cases (14%), and 3 anti-cN1A-positive cases (4%). Compared with the MSA-negative group, the anti-MDA5-positive patients showed significantly higher incidence rates of fever, arthritis, and interstitial lung disease (P<0.05). The anti-NXP2-positive patients exhibited significantly higher incidence rates of calcinosis, fever, soft tissue edema, and interstitial lung disease than the MSA-negative patients (P<0.05). Compared with the anti-MDA5-positive group and MSA-negative group, the anti-NXP2-positive group had significantly higher levels of creatine kinase and creatine kinase isoenzyme (P<0.017) and a significantly lower score of the Childhood Myositis Assessment Scale (P<0.017). Conclusions The positive rate of MSA is high in children with JDM, with different subtypes correlating with specific clinical manifestations and organ involvement. Detection of MSA is crucial for diagnosis and clinical management of JDM.

Copy number alteration (CNA) is a significant genetic change in pediatric B-cell acute lymphoblastic leukemia (B-ALL), with CDKN2A/B deletions, PAX5 deletions, and IKZF1 deletions being the most common. Recent studies have increasingly highlighted the potential prognostic significance of these gene deletions and multiple co-deletions in pediatric B-ALL. This paper reviews the main detection methods for CNA, as well as the prognostic characteristics and treatment approaches for common CNA in pediatric B-ALL.
