Enhanced engraftment of human haematopoietic stem cells via mechanical remodelling mediated by the corticotropin-releasing hormone.

The engraftment of haematopoietic stem and progenitor cells (HSPCs), particularly in cord-blood transplants, remains challenging. Here we report the role of the corticotropin-releasing hormone (CRH) in enhancing the homing and engraftment of human-cord-blood HSPCs in bone marrow through mechanical remodelling. By using microfluidics, intravital two-photon imaging and long-term-engraftment assays, we show that treatment with CRH substantially enhances HSPC adhesion, motility and mechanical remodelling, ultimately leading to improved bone-marrow homing and engraftment in immunodeficient mice.

Rosthornin B alleviates inflammatory diseases via directly targeting NLRP3.

Aberrant activation of the NLRP3 inflammasome contributes to the evolution of diverse inflammatory diseases. Inhibition of the NLRP3 inflammasome has been proven to be an effective treatment strategy for NLRP3-driven diseases. This study revealed that multiple natural diterpenes from Isodon plants can inhibit the NLRP3 inflammasome, among which Rosthornin B (Ros B) exhibited the best inhibitory effect, with an IC of 0.

Gallbladder preserving cholelithotomy in children with hereditary spherocytosis complicated by gallstones: a single-center retrospective study.

Background: Gallstones are among the most common complications of hereditary spherocytosis (HS). In previous treatments, gallbladder-preserving cholelithotomy (GPC) has remained a subject of significant debate due primarily to potential risks of stone recurrence. However, past studies have often overlooked the impact of specific disease conditions on GPC.

Bilateral Patent Processus Vaginalis with Chylous Effusion in a Pediatric Patient: A Rare Case Report and Literature Review.

Background: Chylous effusion is a rare condition characterized by the accumulation of lymphatic fluid in body cavities, often due to trauma, malignancy, or congenital lymphatic abnormalities. The association of chylous effusion with a patent processus vaginalis (PV) in pediatric patients is exceptionally uncommon, presenting unique diagnostic and therapeutic challenges.

Objective: To report a rare case of bilateral patent processus vaginalis with chylous effusion in a pediatric patient, detailing the diagnostic process, surgical management, and outcomes, while contributing to the limited literature on this condition.

Lipopolysaccharide induces neuroinflammation in a valproic acid male model of autism.

Background: Autism spectrum disorders (ASD) are characterized by social skill deficits and behavior impairments. Exposure to valproic acid (VPA) has been linked to ASD in humans and ASD-like behaviors in rodents. Clinical evidence suggests that immunological damage can worsen ASD symptoms in humans.

Clinical Efficacy of Azithromycin in the Treatment of Pediatric Pneumonia and Its Impact on Platelet Count and D-Dimer Levels.

Objective: To analyze the clinical efficacy of azithromycin in the treatment of pediatric pneumonia and its impact on platelet count and D-dimer levels.

Methods: A comparison was made between the two groups regarding clinical treatment effects, recovery status, levels of blood indicators [C-reactive protein (CRP), white blood cell count (WBC), platelet count (PLT), D-dimer (D-D)], and the occurrence of adverse reactions. The control group received conventional symptomatic treatment, while the case group received both conventional treatment and azithromycin.

Research progress and advances in endoplasmic reticulum stress regulation of acute kidney injury.

Acute kidney injury (AKI) is a common and severe clinical disorder in which endoplasmic reticulum (ER) stress plays an important regulatory role. In this review, we summarize the research progress on the relationship between ER stress and AKI. It emphasizes the importance of maintaining a balance between promoting and protecting ER stress during AKI and highlights the potential of ER stress-targeted drugs as a new therapeutic approach for AKI.

Validation of the biological function and prognostic significance of AURKA in neuroblastoma.

Background: Neuroblastoma (NB) is the most common extracranial solid tumor in children, and the AURKA gene encodes a protein kinase involved in cell cycle regulation that plays an oncogenic role in a variety of human cancers. The aim of this study was to validate the biological function and prognostic significance of AURKA in NB using basic experiments and bioinformatics.

Methods: Data obtained from Target and GEO databases were analyzed using various bioinformatic techniques.

Variations in RASA1 and EPHB4 in Chinese patients with capillary malformation-arteriovenous malformation.

Capillary malformation-arteriovenous malformation (CM-AVM) is a genetic condition predominantly attributed to variations in the RASA1 or EPHB4 genes. We identified three genetic variations: a variation in the RASA1 (c.2603+1G>A) and two novel variations in the EPHB4 (c.

Utility of plasma suPAR to identify AKI and sepsis associated AKI in critically ill children.

Current biomarkers for sepsis-associated acute kidney injury (SA-AKI) lack specificity. The role of soluble urokinase plasminogen activator receptor (suPAR) in discriminating AKI and SA-AKI in children remains elusive. This prospective multicenter study was conducted in critically ill children cohorts using a derivation-validation design, and plasma samples were collected within first 24 h after admission.

Present and prospect of transarterial chemoembolization combined with tyrosine kinase inhibitor and PD-1 inhibitor for unresectable hepatocellular carcinoma.

In this editorial, we comment on the article ( 2024; 16: 1236-1247), which is a retrospective study of transarterial chemoembolization (TACE) combined with multi-targeted tyrosine kinase inhibitor (TKI) and programmed cell death protein-1 (PD-1) inhibitor for the treatment of unresectable hepatocellular carcinoma (HCC). Herein, we focus specifically on the mechanisms of this triple therapy, administration sequence and selection of each medication, and implications for future clinical trials. Based on the interaction mechanisms between medications, the triple therapy of TACE + TKI + PD-1 is proposed to complement the deficiency of each monotherapy, and achieve synergistic antitumor effects.

NOTCH1 mitochondria localization during heart development promotes mitochondrial metabolism and the endothelial-to-mesenchymal transition in mice.

Notch signaling activation drives an endothelial-to-mesenchymal transition (EndMT) critical for heart development, although evidence suggests that the reprogramming of endothelial cell metabolism can regulate endothelial function independent of canonical cell signaling. Herein, we investigated the crosstalk between Notch signaling and metabolic reprogramming in the EndMT process. Biochemically, we find that the NOTCH1 intracellular domain (NICD1) localizes to endothelial cell mitochondria, where it interacts with and activates the complex to enhance mitochondrial metabolism.
