Surgical management of children with Burkitt's lymphoma involving the gastrointestinal tract.

Purpose: To investigate the clinical characteristics and surgical management of children with Burkitt's lymphoma (BL) involving the gastrointestinal tract.

Methods: A retrospective analysis was conducted on 87 pediatric patients diagnosed with BL involving the gastrointestinal tract and treated surgically at Beijing Children's Hospital (2008-2022). All patients were histopathologically confirmed with BL and diagnosed with gastrointestinal involvement through imaging studies and surgery.

Prognostic significance of NUAK1 and its association with immune infiltration in stomach adenocarcinoma.

Background: Stomach adenocarcinoma (STAD) represents a significant global health burden, accounting for a considerable proportion of cancer-related mortalities, and NUAK1, a protein kinase, plays a crucial role in cellular metabolism, cell cycle regulation, migration, and tumor progression. However, its relationship with prognosis and immune infiltration in STAD has not been thoroughly investigated.

Methods: RNA sequencing data from the Cancer Genome Atlas (TCGA) and Genotypic Tissue Expression Project (GTEx) databases were employed to assess disparities in NUAK1 expression between STAD tumour and normal tissues.

Methods: The study included 52 children with ADHD aged 4.0-9.

Association between reported ADHD symptom and motor development delay in preschool children.

Objective: To explore whether the motor developmental level is associated with the attention deficit/hyperactivity disorder (ADHD) symptoms severity reported by parents in preschool children.

Methods: Preschool children aged 4-6 years old with the chief complaint of reported inattention or hyperactivity by kindergarten teachers or parents were recruited in this study. All participants were consulted by at least one experienced developmental behavior pediatrician, according to DSM-V diagnostic criteria of ADHD.

Spatial and Single Cell Analyses Reveal Heterogeneity of DNAM-1 Receptor-Ligand Interactions that Instructs Intratumoral γδT-Cell Activity.

The dynamic interplay between tumor cells and γδT cells within the tumor microenvironment (TME) significantly influences disease progression and immunotherapy outcome. Here, we delved into the modulation of γδT-cell activation by tumor cell ligands CD112 and CD155, which interact with the activating receptor DNAM-1 on γδT cells. Spatial and single cell RNA sequencing (scRNA-seq), as well as spatial metabolome analysis, from neuroblastoma (NB) revealed that the expression levels and localization of CD112 and CD155 varied across and within tumors, correlating with differentiation status, metabolic pathways, and ultimately disease prognosis and patient survival.

Targeted gene sequencing and hearing follow-up in 7501 newborns reveals an improved strategy for newborn hearing screening.

Hearing loss is a common congenital condition. Concurrent newborn hearing and limited genetic screening has been implemented in China for the last decade. However, the role of gene sequencing screening has not been evaluated.

Ziresovir in Hospitalized Infants with Respiratory Syncytial Virus Infection.

Background: Respiratory syncytial virus (RSV) is a leading cause of severe illness in infants, with no effective treatment. Results of a phase 2 trial suggested that ziresovir may have efficacy in the treatment of infants hospitalized with RSV infection.

Methods: In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial conducted in China, we enrolled participants 1 to 24 months of age who were hospitalized with RSV infection.

Exploratory Study of Relationship Between Obstructive Sleep Apnea Syndrome and Growth Hormones and Inflammatory Factors in Children.

In children, obstructive sleep apnea (OSA) is associated with growth hormone level abnormalities and chronic systemic inflammation. This study was performed to investigate the relationship of the degree of OSA with insulin-like growth factor 1 (IGF-1) and inflammatory cytokines in pediatric OSA and the inter-relationship between inflammatory cytokines and growth hormones. Children with OSA and controls without OSA participated in the study.

Improved Binaural Hearing Effects and Sound Source Localization in Listeners with Simulated Unilateral Conductive Hearing Loss: Effect of a Bone Conduction Device.

It has been proven that patients with unilateral conductive hearing loss (UCHL) may encounter typical problems associated with asymmetric hearing, especially in challenging listening environments. In this study, we aimed to determine how UCHL affects speech recognition under multisource competing environments and the ability of sound source localization, as well as whether assistance with a bone conduction device (BCD) can confer hearing benefits in such listening tasks. Acquired UCHL was simulated using an earplug combined with an earmuff in 10 listeners (mean age: 29.

Dynamically Regulating Homologous Recombination Enables Precise Genome Editing in .

Methylotrophic yeast has become a promising cell factory due to its efficient utilization of methanol to produce high value-added chemicals. However, the low homologous recombination (HR) efficiency in greatly hinders extensive metabolic engineering for industrial applications. Overexpression of HR-related genes successfully improved HR efficiency, which however brought cellular stress and reduced chemical production due to constitutive expression of the HR-related gene.

Clinical outcomes and prognostic factors of parameningeal rhabdomyosarcoma in children and adolescents: results of two consecutive protocols.

Background: Parameningeal rhabdomyosarcoma (PM-RMS) accounts for about 20% of all rhabdomyosarcoma (RMS) cases. At present, most research on PM-RMS has been conducted in Europe and the United States of America, and research in China has been very limited. This study sought to analyze the clinical outcomes and prognostic factors of PM-RMS in children and adolescents from two consecutive protocols at Beijing Children's Hospital (BCH).

A Decade of Single-Center Experience in Children With Congenital Pyriform Sinus Fistula (CPSF).

Objectives: To investigate the efficacy and safety of carbon dioxide (CO) laser cauterization in the treatment of pediatric congenital pyriform sinus fistula (CPSF), and to track and follow up the long-term outcome of the postoperative patients.

Methods: This retrospective study was conducted at a single center, where clinical data and follow-up information of children with CPSF who underwent CO laser cauterization with the assistance of a suspension laryngoscope and microscope were collected and analyzed their clinical characteristics and prognosis. Subsequently, multiple logistic regression analysis was performed to identify potential predictors of the number of laser cauterization procedures.

Therapeutic SHPRH-146aa encoded by circ-SHPRH dynamically upregulates P21 to inhibit CDKs in neuroblastoma.

Recent research has underscored the significance of circular RNAs (circRNAs) in various cancers, including neuroblastoma (NB). Specifically, circ-SHPRH, a unique circRNA, has been revealed to inhibit tumor growth by sequestering miRNAs or producing the SHPRH-146aa protein. To explore circ-SHPRH's involvement in NB and its potential application in gene therapy, this study examined circ-SHPRH expression in 94 NB tissues and cell lines (SK-N-BE(2), SH-SY5Y) using real-time PCR and fluorescence in situ hybridization (FISH).

Modulation of mercaptopurine intestinal toxicity and pharmacokinetics by gut microbiota.

The interaction between the gut microbiota and mercaptopurine (6-MP), a crucial drug used in pediatric acute lymphoblastic leukemia (ALL) treatment, has not been extensively studied. Here we reveal the significant perturbation of gut microbiota after 2-week 6-MP treatment in beagles and mice followed by the functional prediction that showed impairment of SCFAs production and altered amino acid synthesis. And the targeted metabolomics in plasma also showed changes in amino acids.

Design, synthesis and biological evaluation of 5H-[1,2,4]triazino[5,6-b]indole derivatives bearing a pyridinocycloalkyl moiety as iron chelators.

The avidity of cancer cells for iron highlights the potential for iron chelators to be used in cancer therapy. Herein, we designed and synthesized a novel series of 5H-[1,2,4]triazino[5,6-b]indole derivatives bearing a pyridinocycloalkyl moiety using a ring-fusion strategy based on the structure of an iron chelator, VLX600. The antiproliferative activity evaluation against cancer cells and normal cells led to the identification of compound 3k, which displayed the strongest antiproliferative activity in vitro against A549, MCF-7, Hela and HepG-2 with IC values of 0.
