It analyzes current challenges in clinical practice, education and teaching, scientific research, doctor-patient consensus, and social recognition. Furthermore, it proposes directions for effort, namely, in the context of "greater health" and "new medical science", narrative medicine is empowered to help construct a harmonious medical narrative ecosystem, promote high-quality development in pediatrics, contribute to the innovation in medical education and talent training with humanistic strength and wisdom.

Abstract:In the clinical diagnosis and treatment of children with short stature, mental health issues merit special attention. It is widely acknowledged that the psychological well-being of children with short stature is lower than that of their peers with normal height. Therefore, during the diagnosis, treatment, and care of short stature, it is crucial to actively monitor the mental health of these children, promptly identify potential psychological and behavioral issues, and intervene accordingly. Such measures play a positive role in enhancing the quality of life of these children and improving their physical and mental health. This article analyses and discusses the current state of psychological assessment and psycho-behavioral interventions for children with short stature, aiming to provide insights for improving their mental health.

Abstract:Objective To investigate the effects of different angles of pulmonary surfactant (PS) administration on the incidence of bronchopulmonary dysplasia and intracranial hemorrhage in preterm infants.Methods A prospective study was conducted on 146 preterm infants (gestational age <32 weeks) admitted to the Department of Neonatology, Provincial Hospital Affiliated to Anhui Medical University from January 2019 to May 2023. The infants were randomly assigned to different angles for injection of pulmonary surfactant groups: 0° group (34 cases), 30° group (36 cases), 45° group (38 cases), and 60° group (38 cases). Clinical indicators and outcomes were compared among the groups.Results The oxygenation index was lower in the 60° group compared with the other three groups, with shorter invasive ventilation time and oxygen use time, and a lower incidence of bronchopulmonary dysplasia than the other three groups (P<0.05). The incidence of intracranial hemorrhage was lower in the 60° group compared to the 0° group (P<0.05). The cure rate in the 60° group was higher than that in the 0° group and the 30° group (P<0.05).Conclusions The clinical efficacy of injection of pulmonary surfactant at a 60° angle is higher than other angles, reducing the incidence of intracranial hemorrhage and bronchopulmonary dysplasia in preterm infants.

Abstract:Objective To investigate the risk factors for the failure of ibuprofen treatment in preterm infants with hemodynamically significant patent ductus arteriosus (hsPDA).Methods A retrospective collection of clinical data was conducted on preterm infants with a gestational age of <34 weeks who were diagnosed with hsPDA and treated at the Department of Neonatology, Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology, from January 2018 to June 2023. The subjects were divided into two groups based on the treatment approach: the ibuprofen group (95 cases) and the ibuprofen plus surgery group (44 cases). The risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA were identified by binary logistic regression analysis.Results The binary logistic regression analysis revealed that an increased diameter of the ductus arteriosus, a resistance index (RI) value of the middle cerebral artery ≥0.80, and prolonged total invasive mechanical ventilation time were risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). Receiver operating characteristic curve analysis showed that a ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days had significant predictive value for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). The combined predictive value of these three factors was the highest, with an area under the curve of 0.843, a sensitivity of 86.5%, and a specificity of 75.0% (P<0.05).Conclusions A ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days are risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA, and they are of significant predictive value for the necessity of surgical treatment following the failure of ibuprofen treatment.

Abstract:Objective To study the pathogen composition and antimicrobial resistance characteristics in neonates with sepsis in the Hebei area, providing a basis for optimizing the management strategies for neonatal sepsis in the region.Methods The medical data of neonates with sepsis confirmed by blood culture from 23 hospitals in Hebei Province were collected prospectively from November 1, 2021 to December 31, 2022. The pathogen composition and antimicrobial resistance characteristics were analyzed in early-onset sepsis (EOS), community-acquired late-onset sepsis (CALOS), and hospital-acquired late-onset sepsis (HALOS) cases.Results A total of 289 neonates were included, accounting for 292 infection episodes, with 117 (40.1%) EOS, 95 (32.5%) CALOS, and 80 (27.4%) HALOS cases. A total of 294 pathogens were isolated, with 118 (40.1%) from the EOS group, where Escherichia coli (39 strains, 33.0%) and coagulase-negative staphylococci (13 strains, 11.0%) were the most common. In the CALOS group, 95 pathogens were isolated (32.3%), with Escherichia coli (35 strains, 36.8%) and group B Streptococcus (14 strains, 14.7%) being predominant. The HALOS group yielded 81 isolates (27.6%), with Klebsiella pneumoniae (24 strains, 29.6%) and Escherichia coli (21 strains, 25.9%) as the most frequent. Coagulase-negative staphylococci showed over 80% resistance to penicillin antibiotics. Escherichia coli and Klebsiella pneumoniae showed a resistance rate of 2.2% to 75.0% to common β-lactam antibiotics. The resistance rates of predominant Gram-negative bacteria in the HALOS group to common β-lactam antibiotics were higher than those in the CALOS group.Conclusions In the Hebei region, Escherichia coli is the most common pathogen in both EOS and LOS. There are differences in the composition and antimicrobial resistance of pathogens among different types of neonatal sepsis. The choice of empirical antimicrobial drugs should be based on the latest surveillance data from the region.

Abstract:Objective To study the distribution, drug resistance, and biofilm characteristics of carbapenem-resistant Acinetobacter baumannii (CRAB) isolated from hospitalized children, providing a reference for the prevention and treatment of CRAB infections in hospitalized children.Methods Forty-eight CRAB strains isolated from January 2019 to December 2022 were classified into epidemic and sporadic strains using repetitive extragenic palindromic sequence-based polymerase chain reaction. The drug resistance, biofilm phenotypes, and gene carriage of these two types of strains were compared.Results Both the 22 epidemic strains and the 26 sporadic strains were producers of Class D carbapenemases or extended-spectrum β-lactamases with downregulated outer membrane porins, harboring the VIM, OXA-23, and OXA-51 genes. The biofilm formation capability of the sporadic strains was stronger than that of the epidemic strains (P<0.05). Genes related to biofilm formation, including Bap, bfs, OmpA, CsuE, and intI1, were detected in both epidemic and sporadic strains, with a higher detection rate of the intI1 gene in epidemic strains (P<0.05).Conclusions CRAB strains are colonized in the hospital, with sporadic strains having a stronger ability to form biofilms, suggesting the potential for forming new clonal transmissions in the hospital. Continuous monitoring of the epidemic trends of CRAB and early warning of the distribution of epidemic strains are necessary to reduce the risk of CRAB infections in hospitalized children.

Abstract:Objective To summarize the clinical characteristics, treatment outcomes, and prognostic factors of children with non-metastatic Ewing's sarcoma (ES).Methods A retrospective analysis was conducted on the clinical data of 41 children with non-metastatic ES diagnosed and treated at the Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine from January 2010 to December 2018. All patients underwent chemotherapy based on the RMS-2009 protocol of the center, and local treatment such as surgery and/or radiotherapy was performed according to risk grouping. The Kaplan-Meier method was used to calculate the overall survival (OS) and event-free survival (EFS) rates. Univariate prognostic analysis was performed using the log-rank test, and multivariate analysis was conducted with Cox regression.Results Of the 41 children, 21 were male and 20 were female. The median age at diagnosis was 7.7 years (range: 1.2-14.6 years). The median follow-up time for patients with event-free survival was 68.1 months (range: 8.1-151.7 months). As of the last follow-up, 33 patients were in complete remission, and the overall 5-year EFS and OS rates were (78±6)% and (82±6)%, respectively. Univariate analysis by the log-rank test showed that a tumor diameter ≥8 cm, time from diagnosis to start of local treatment ≥16 weeks, and incomplete surgical resection were associated with poor prognosis (P<0.05). Multivariate Cox regression analysis indicated that incomplete surgical resection (HR=8.381, 95%CI: 1.681-41.801, P=0.010) was an independent risk factor for poor prognosis in children with ES. Secondary tumors occurred in 2 cases.Conclusions A comprehensive treatment strategy incorporating chemotherapy, surgery, and radiotherapy can improve the prognosis of children with ES. Poor prognosis is associated with an initial tumor diameter ≥8 cm, while complete surgical resection and early initiation of local treatment can improve outcomes.

Abstract:Objective To investigate the levels of serum folate and vitamin B₁₂ (VB₁₂) and their association with the level of neurodevelopment in preschool children with autism spectrum disorder (ASD).Methods A total of 324 ASD children aged 2-6 years and 318 healthy children aged 2-6 years were recruited. Serum levels of folate and VB₁₂ were measured using chemiluminescent immunoassay. The Social Responsiveness Scale and the Childhood Autism Rating Scale were used to assess the core symptoms of ASD children, and the Gesell Developmental Schedule was employed to evaluate the level of neurodevelopment.Results The levels of serum folate and VB₁₂ in ASD children were significantly lower than those in healthy children (P<0.05). Serum folate levels in ASD children were positively correlated with gross and fine motor developmental quotients (P<0.05), and serum VB₁₂ levels were positively correlated with adaptive behavior, fine motor, and language developmental quotients (P<0.05). In ASD children aged 2 to <4 years, serum folate levels were positively correlated with developmental quotients in all domains (P<0.05), and serum VB₁₂ levels were positively correlated with language developmental quotient (P<0.05). In male ASD children, serum VB₁₂ levels were positively correlated with language and personal-social developmental quotients (P<0.05).Conclusions Serum folate and VB₁₂ levels in preschool ASD children are lower than those in healthy children and are associated with neurodevelopmental levels, especially in ASD children under 4 years of age. Therefore, maintaining normal serum folate and VB₁₂ levels may be beneficial for the neurodevelopment of ASD children, especially in ASD children under 4 years of age.

Abstract:Objective To dynamically observe the changes in hypoxia-inducible factor 1α (HIF-1α) and Bcl-2/adenovirus E1B19kDa-interacting protein 3 (BNIP3) in children with traumatic brain injury (TBI) and evaluate their clinical value in predicting the severity and prognosis of pediatric TBI.Methods A prospective study included 47 children with moderate to severe TBI from January 2021 to July 2023, categorized into moderate (scores 9-12) and severe (scores 3-8) subgroups based on the Glasgow Coma Scale. A control group consisted of 30 children diagnosed and treated for inguinal hernia during the same period, with no underlying diseases. The levels of HIF-1α, BNIP3, autophagy-related protein Beclin-1, and S100B were compared among groups. The predictive value of HIF-1α, BNIP3, Beclin-1, and S100B for the severity and prognosis of TBI was assessed using receiver operating characteristic (ROC) curves.Results Serum levels of HIF-1α, BNIP3, Beclin-1, and S100B in the TBI group were higher than those in the control group (P<0.05). Among the TBI patients, the severe subgroup had higher levels of HIF-1α, BNIP3, Beclin-1, and S100B than the moderate subgroup (P<0.05). Correlation analysis showed that the serum levels of HIF-1α, BNIP3, Beclin-1, and S100B were negatively correlated with the Glasgow Coma Scale scores (P<0.05). After 7 days of treatment, serum levels of HIF-1α, BNIP3, Beclin-1, and S100B in both non-surgical and surgical TBI patients decreased compared to before treatment (P<0.05). ROC curve analysis indicated that the areas under the curve for predicting severe TBI based on serum levels of HIF-1α, BNIP3, Beclin-1, and S100B were 0.782, 0.835, 0.872, and 0.880, respectively (P<0.05), and for predicting poor prognosis of TBI were 0.749, 0.775, 0.814, and 0.751, respectively (P<0.05).Conclusions Serum levels of HIF-1α, BNIP3, and Beclin-1 are significantly elevated in children with TBI, and their measurement can aid in the clinical assessment of the severity and prognosis of pediatric TBI.

Abstract:Further evidence is needed to explore the impact of high-altitude environments on the neurologic function of neonates. Non-invasive techniques such as cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography can provide data on cerebral oxygenation and brain electrical activity. This study will conduct multiple cerebral near-infrared spectroscopy and amplitude-integrated electroencephalography monitoring sessions at various time points within the first 3 days postpartum for healthy full-term neonates at different altitudes. The obtained data on cerebral oxygenation and brain electrical activity will be compared between different altitudes, and corresponding reference ranges will be established. The study involves 6 participating centers in the Chinese High Altitude Neonatal Medicine Alliance, with altitude gradients divided into 4 categories: 800 m, 1 900 m, 2 400 m, and 3 500 m, with an anticipated sample size of 170 neonates per altitude gradient. This multicenter prospective cohort study aims to provide evidence supporting the impact of high-altitude environments on early brain function and metabolism in neonates.

Abstract:The first patient, a 10-year-old girl, presented with pancytopenia and recurrent epistaxis, along with a history of repeated upper respiratory infections, café-au-lait spots, and microcephaly. Genetic testing revealed compound heterozygous mutations in the DNA ligase IV (LIG4) gene, leading to a diagnosis of LIG4 syndrome. The second patient, a 6-year-old girl, was seen for persistent thrombocytopenia lasting over two years and was noted to have short stature, hyperpigmented skin, and hand malformations. She had a positive result from chromosome breakage test. She was diagnosed with Fanconi anemia complementation group A. Despite similar clinical presentations, the two children were diagnosed with different disorders, suggesting that children with hemocytopenia and malformations should not only be evaluated for hematological diseases but also be screened for other potential underlying conditions such as immune system disorders.

Abstract:Autism spectrum disorder (ASD) is one of the neurodevelopmental disorders in children, and there are currently no specific treatments, with the main interventions focusing on educational training and behavioral correction. Virtual reality, as an emerging technology, is a computer-based environmental simulation system that achieves interactive dynamics and immersive experiences by integrating information from multiple sources. In recent years, it has been gradually applied in intervention training for children with ASD. This paper reviews the recent studies on the effects of virtual reality intervention on emotional cognition, social skills, daily living skills, motor skills, and specific phobias in children with ASD, offering a new direction for ASD intervention training.

With the emergence of disease-modifying therapies, the prognosis of SMA has significantly improved, drawing increased attention to the importance of home rehabilitation and nursing management. Long-term, standardized home rehabilitation and nursing can delay the progression of SMA, enhance the psychological well-being, and improve the quality of life of both patients and caregivers. This article provides an overview of the goals of home rehabilitation, basic functional training methods, respiratory management, and nutritional management for SMA patients, as well as psychological health issues, emphasizing the significance of obtaining appropriate home rehabilitation and support during the care process.

Abstract:Pulmonary arterial hypertension (PAH) is a severe disease characterized by abnormal pulmonary vascular remodeling and increased right ventricular pressure load, posing a significant threat to patient health. While some pathological mechanisms of PAH have been revealed, the deeper mechanisms of pathogenesis remain to be elucidated. In recent years, bioinformatics has provided a powerful tool for a deeper understanding of the complex mechanisms of PAH through the integration of techniques such as multi-omics analysis, artificial intelligence, and Mendelian randomization. This review focuses on the bioinformatics methods and technologies used in PAH research, summarizing their current applications in the study of disease mechanisms, diagnosis, and prognosis assessment. Additionally, it analyzes the existing challenges faced by bioinformatics and its potential applications in the clinical and basic research fields of PAH in the future.

Abstract:The patient, a male newborn, was admitted to the hospital 2 hours after birth due to prematurity (gestational age 27⁺⁵ weeks) and respiratory distress occurring 2 hours postnatally. After admission, the infant developed fever and elevated C-reactive protein levels. On the fourth day after birth, metagenomic next-generation sequencing of cerebrospinal fluid indicated a positive result for Mycoplasma hominis (9 898 reads). On the eighth day, a retest of cerebrospinal fluid metagenomics confirmed Mycoplasma hominis (56 806 reads). The diagnosis of purulent meningitis caused by Mycoplasma hominis was established, and the antibiotic treatment was switched to moxifloxacin [5 mg/(kg·day)] administered intravenously for a total of 4 weeks. After treatment, the patient's cerebrospinal fluid tests returned to normal, and he was discharged as cured on the 76th day after birth. This article focuses on the diagnosis and treatment of neonatal Mycoplasma hominis purulent meningitis, introducing the multidisciplinary diagnosis and treatment of the condition in extremely preterm infants.
