This is a single-center, investigator-initiated, prospective observational case-control study. Patients with intracerebral hemorrhage and healthy controls will be enrolled at Xuanwu Hospital, Capital Medical University. Peripheral venous blood samples will be collected for measurement of CIRP, Cathepsin B, and related inflammatory biomarkers. Clinical and imaging data will also be collected in the intracerebral hemorrhage group. The study aims to compare biomarker levels between patients with intracerebral hemorrhage and healthy controls and to explore the potential role of these biomarkers in neuroinflammation after intracerebral hemorrhage. No investigational treatment will be administered.
