Effect of growth hormone on bone density and body composition in Chinese patients with transitional growth hormone deficiency.

This study evaluated the effects of recombinant human growth hormone (rhGH) on bone mineral density (BMD) and body composition in Chinese adolescents with transitional growth hormone deficiency (TGHD). A prospective cohort study was conducted from September 2021 to September 2024, involving 37 TGHD patients (15-18 years) and 7 healthy controls. After a 3-month rhGH washout, 9 confirmed TGHD patients (diagnosed per 2019 AACE criteria) were stratified into treatment (n = 4, rhGH continuation) and non-treatment (n = 5) groups.

Roles and Molecular Mechanisms of Serum Exosomal miRNA-223 and miRNA-132 in Juvenile Idiopathic Arthritis.

Introduction: The pathogenesis of juvenile idiopathic arthritis (JIA) has not yet been clarified and is closely related to persistent overactivation of the JAK/STAT signaling pathway. MicroRNA (miRNA)-223 (miR-223) and miRNA-132 (miR-132) might be involved in the development of JIA. However, the mechanism underlying the pathogenesis of JIA is unclear.

Bacterial distribution and drug resistance in blood samples of children in Jiangxi Region, 2017-2021.

Objective: This study aims to investigate the distribution and drug resistance of bacteria in clinical blood culture specimens from children in Jiangxi province in recent years and to provide a foundation for preventing and treating bloodstream infection diseases in children.

Methods: The study involved a statistical analysis of the isolation and drug resistance of bacterial strains obtained from blood culture specimens of children in Jiangxi province between 2017 and 2021. The analysis was performed using the WHONET 5.

Re-evaluate the Prognostic Value of Absolute Lymphocyte Count in Pediatric Immune Thrombocytopenia.

To re-evaluate the prognostic value of absolute lymphocyte count (ALC) in pediatric immune thrombocytopenia (ITP) from the perspective of age. A total of 242 ITP pediatric patients, including 141 newly diagnosed ITP (nITP), 89 chronic ITP (cITP), and 12 persistent ITP, were retrospectively reviewed for this study. These patients were divided into 3 groups according to age (group 1, ≤24 m; group 2, 24-72 m; and group 3, >72 m).

Surveillance of carbapenem-resistant in a paediatric hospital in China revealed the dynamics of carbapenemase and the prevalence of ST2735 .

Carbapenem-resistant (CRKP) is increasingly isolated in paediatric wards, posing a severe threat to these vulnerable populations. This study investigated the clinical features, determinants of carbapenem resistance and clonal relatedness among CRKP in our hospital. The prevalence of carbapenem-resistant in paediatric patients differs from the strains isolated from adult patients in carbapenemase and predominant clones.

The association between polymorphisms in PITX2 and congenital esophageal atresia susceptibility.

Objective: This study aims to investigate and analyze the connection between PITX2 polymorphisms and the susceptibility of congenital esophageal atresia.

Methods: From January 2015 to June 2020, 46 children with congenital esophageal atresia undergoing surgery were recruited for the study and placed in an observation group, and 40 neonates born in pediatrics during the same period were also recruited for the study and placed in a control group. The alleles and distribution frequencies of the polymorphisms of PITX2 gene rs2200733 were analyzed, and the odds ratio (OR) of esophageal atresia caused by the rs2200733 polymorphism were calculated using a logistic analysis.

Pertussis detection in children with cough of any duration.

Background: The diagnosis of pertussis in clinical practice continues to be a challenge worldwide as the symptoms are variable. We aimed to determine the prevalence of pertussis in Chinese children irrespective of cough duration and explore the clinical characteristics of children with pertussis with different cough durations.

Methods: This was a prospective study of children 1 month to 11 years of age with different cough durations in one large Chinese hospital.

[Effects of recombinant fusion protein interleukin-18 on expression of immune-inflammatory factors in mice infected with Staphylococcus aureus].

Objective: To observe the effects of recombinant fusion protein interleukin (IL)-18 on the expression of immune-inflammatory factors in the mice infected with Staphylococcus aureus (SA), and to investigate the mechanism of action of IL-18 in defense of SA infection in vivo.

Methods: A total of 40 specific pathogen-free female BLAB/c mice were randomly divided into four groups: control, SA infection, immunized, and intervention. A mouse model of SA infection was established by nasal inoculation with SA liquid.

[Immunological mechanism of wheezing attack in children with cytomegalovirus infection].

Objective: To study the possible immunological mechanism of wheezing attack in children with cytomegalovirus (CMV) infection.

Methods: A total of 25 under-5-year-old children with wheezing following CMV infection were enrolled. The expression of serum regulatory T cells (Treg)/T helper 17 (Th17) cytokines interleukin (IL)-10, IL-6, and IL-17, and peripheral blood lymphocyte subsets were determined.

[Effects of sublingual immunotherapy on serum IL-17 and IL-35 levels in children with allergic rhinitis or asthma].

Objective: To study the clinical effect and mechanisms of specific sublingual immunotherapy (SLIT) for the treatment of allergic rhinitis or asthma in children.

Methods: Thirty children suffering from Dermatophagoides farinae-allergic rhinitis or asthma (case group) and 30 healthy children (control group) were enrolled in this study. The case group accepted SLIT between January and December 2011.

Ribosomopathies: mechanisms of disease.

Ribosomopathies are diseases caused by alterations in the structure or function of ribosomal components. Progress in our understanding of the role of the ribosome in translational and transcriptional regulation has clarified the mechanisms of the ribosomopathies and the relationship between ribosomal dysfunction and other diseases, especially cancer. This review aims to discuss these topics with updated information.

[Clinical analysis of immune function changes in children with bronchial pneumonia].

Objective: To investigate changes in serum complement, immunoglobulins and lymphocyte subsets in children with common and severe bronchial pneumonia, and the role of immune function testing in bronchial pneumonia.

Methods: Twenty children with common bronchial pneumonia, 20 with severe bronchial pneumonia and 20 healthy children (as controls) were enrolled in this study. Immunization rate scattering turbidimetry and six-color flow cytometry were used to detect changes in serum levels of IgA, IgG and IgM, complement C3 and C4 and CD3(+), CD4(+), CD8(+), CD16(+), CD56(+) and CD19(+) cells.
