Objective: To evaluate the changes in apoptosis of neutrophil in peripheral blood in sepsis in rats.
Methods: The rat sepsis model was reproduced by cecum ligation and puncture (CLP). One hundred and forty-four rats were randomly divided into normal control group, sham operation group and 2, 6, 12, 24, 48, 72 hours after CLP groups. Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) was used to identify neutrophil apoptosis.
Results: In early period after CLP, neutrophil apoptosis in peripheral blood was limited with a positive rate of less than 5.00%. The positive rate rose to (48.33+/-12.53)% at 48 hours, and it began to lower, approaching the normal level at 72 hours after CLP.
Conclusion: Death is the main pathway of loss of neutrophils which are produced in the acute phase of sepsis, and apoptosis is the main pathway of loss of neutrophil in the later phase of sepsis.
Background: Computational modeling indicated that pathological high shear stress (HSS; 100 dyn/cm) is generated in pulmonary arteries (PAs; 100-500 µm) in congenital heart defects causing PA hypertension (PAH) and in idiopathic PAH with occlusive vascular remodeling. Endothelial-to-mesenchymal transition (EndMT) is a feature of PAH. We hypothesize that HSS induces EndMT, contributing to the initiation and progression of PAH.
There are many causes of peripheral blood eosinophilia (PBE), including allergic, infectious, rheumatic, and hematologic disorders. Solid tumor cancers, such as lung cancer, can also cause PBE, and although rare, being diagnosed with PBE in this way is associated with a worse prognosis than for lung cancer patients without PBE. Additionally, some cancer patients develop PBE when receiving treatment with immune checkpoint inhibitors (ICIs).

Introduction: Pediatric sarcomas, including osteosarcoma (OS), Ewing sarcoma (EwS) and rhabdomyosarcoma (RMS) carry low somatic mutational burden and low MHC-I expression, posing a challenge for T cell therapies. Our previous study showed that mediators of monocyte maturation sensitized the EwS cell line A673 to lysis by HLA-A*02:01/CHM1-specific allorestricted T cell receptor (TCR) transgenic CD8 T cells (CHM1 CD8 T cells).
Methods: In this study, we tested a panel of monocyte maturation cytokines for their ability to upregulate immunogenic cell surface markers on OS, EwS and RMS cell lines, using flow cytometry.
Background: Cognitive frailty (), characterized by the coexistence of physical frailty and cognitive impairment, is linked to increased morbidity and mortality in older adults. While has been linked to multiple physiological and lifestyle factors, the underlying biological mechanisms remain poorly understood. This study investigated the risk factors for and explored the relationship between mitochondrial function and in hospitalized patients.
Introduction: China has the largest population of individuals with diabetes, and the prevalence of various complications among patients with type 2 diabetes remains high. Diabetic nephropathy affects approximately 20% to 40% of diabetic patients, becoming a major cause of chronic kidney disease and end-stage renal disease. Furthermore, around 50% of patients develop diabetic peripheral neuropathy (DPN), which is closely associated with physical disability, increased healthcare costs, and reduced work productivity.
