Mast cell leukemia: a rare case report and literature review.

Mast cell leukemia (MCL) is an extremely rare and aggressive hematologic malignancy, characterized by a poor prognosis and short survival. Currently, no standardized treatment guidelines have been established. This study presents the clinical data of a patient with primary MCL accompanied by C-findings, and analyzes the clinical features, diagnostic challenges, and therapeutic approaches for this disease through a comprehensive review of the relevant literature.

Microglia programmed cell death in neurodegenerative diseases and CNS injury.

Programmed cell death (PCD) has emerged as a critical regulatory mechanism in the initiation and progression of various pathological conditions. PCD in microglia, including necroptosis, pyroptosis, apoptosis, ferroptosis, and autophagy, occurs in a variety of central nervous system (CNS) diseases. Dysregulation of microglia can lead to excessive tissue damage or neuronal death in CNS injury.

Prevalence and associated factors of adolescent psychological abuse, neglect in Western China a multi-center cross-sectional study.

The western region of China has a dense population, relatively underdeveloped economy, and a significant number of left-behind children. Currently, the prevalence of adolescent psychological abuse, neglect, and the factors associated with these issues in the region remain unclear. This study aims to evaluate the current status of adolescent psychological abuse and neglect and its associated factors in this region.

Research on the Surface-State Parameterization of a Refill Friction Stir Spot Welding Joint Made of Aluminum Alloy and Its Connection to the Fracture Mode.

Surface features are crucial for assessing welding quality because they serve as an intuitive depiction of the quality of the joint and have a major influence on welding strength. According to the characteristics of the refill friction stir spot welding (RFSSW) process and an analysis of the surface-state and internal morphology of RFSSW joints, a method of predicting the mechanical properties of RFSSW joints based on surface-state characteristics was proposed. In this paper, a laser-ranging sensor was used to characterize the surface state of RFSSW joints, and parametric characterization methods of the surface-state features of RFSSW joints were proposed.

Targeted mRNA Nanoparticles Ameliorate Blood-Brain Barrier Disruption Postischemic Stroke by Modulating Microglia Polarization.

The ischemic stroke is a major global health concern, with high mortality and disability rates. Unfortunately, there is a dearth of effective clinical interventions for managing poststroke neuroinflammation and blood-brain barrier (BBB) disruption that are crucial for the brain injury evolving and neurological deficits. By leveraging the pathological progression of an ischemic stroke, we developed an M2 microglia-targeting lipid nanoparticle (termed MLNP) approach that can selectively deliver mRNA encoding phenotype-switching interleukin-10 (m) to the ischemic brain, creating a beneficial feedback loop that drives microglial polarization toward the protective M2 phenotypes and augments the homing of m-loaded MLNPs (m@MLNPs) to ischemic regions.

Polydatin alleviates mycoplasma pneumoniae-induced injury via inhibition of Caspase-1/GSDMD-dependent pyroptosis.

Mycoplasma pneumoniae (MP) is one of the main pathogens causing community acquired pneumonia (CAP) in children and adults. Previous pharmacological and clinical studies have shown that Polydatin (PD) exerts anti-inflammatory action by conferring protective benefit in MP pneumonia. However, the mechanism underlying the of PD on MP infection remains unclear.

The multifaceted roles of activating transcription factor 3 (ATF3) in inflammatory responses - Potential target to regulate neuroinflammation in acute brain injury.

Activating transcription factor 3 (ATF3) is one of the most important transcription factors that respond to and exert dual effects on inflammatory responses. Recently, the involvement of ATF3 in the neuroinflammatory response to acute brain injury (ABI) has been highlighted. It functions by regulating neuroimmune activation and the production of neuroinflammatory mediators.

Myeloid-derived MIF drives RIPK1-mediated cerebromicrovascular endothelial cell death to exacerbate ischemic brain injury.

Macrophage migration inhibitory factor (MIF) is a multifaced protein that plays important roles in multiple inflammatory conditions. However, the role of MIF in endothelial cell (EC) death under inflammatory condition remains largely unknown. Here we show that MIF actively promotes receptor-interacting protein kinase 1 (RIPK1)-mediated cell death under oxygen-glucose deprivation condition.

Effect of spleen-invigorating, Qi-replenishing and blood-arresting formula on zebrafish models with simvastatin-induced hemorrhage caused by spleen failing to control blood, in terms of theory of Traditional Chinese Medicine.

Objective: To investigate the hemostasis effect of spleen-invigorating, Qi-replenishing and blood-arresting formula, on a zebrafish models with simvastatin-induced hemorrhage, and with symptom pattern caused by spleen failing to control blood, in terms of theory of Traditional Chinese Medicine (TCM).

Methods: In the first experiment, 60 AB strain wild type zebrafishes were randomly assigned into two groups: normal group and model group. The model group was treated with 50 µM simvastatin for 24 h.
