Unraveling the role of HIF-1α in sepsis: from pathophysiology to potential therapeutics-a narrative review.

Sepsis is characterized by organ dysfunction resulting from a dysregulated inflammatory response triggered by infection, involving multifactorial and intricate molecular mechanisms. Hypoxia-inducible factor-1α (HIF-1α), a notable transcription factor, assumes a pivotal role in the onset and progression of sepsis. This review aims to furnish a comprehensive overview of HIF-1α's mechanism of action in sepsis, scrutinizing its involvement in inflammatory regulation, hypoxia adaptation, immune response, and organ dysfunction.

Dyslipidemia versus obesity as predictors of ischemic stroke prognosis: a multi-center study in China.

Background: This multicenter observational study aimed to determine whether dyslipidemia or obesity contributes more significantly to unfavorable clinical outcomes in patients experiencing a first-ever ischemic stroke (IS).

Endoscopic therapy combined with photodynamic therapy for intratracheal inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumor (IMT) is a rare intermediate tumor that exhibits both benign and malignant behaviors. Whether IMT is an inflammatory or a neoplastic disease remains controversial, and there is currently no standard treatment for this disease. The treatment strategies include surgical tumor removal and drug therapy; however, several patients experience tumor recurrence post-treatment.
