This is an observational, multicenter study aimed at investigating the inflammation phenotypes in sputum samples from patients with non-cystic fibrosis bronchiectasis (NCFBE). The study will observe and classify these phenotypes during the clinical screening phase without any intervention. Patients enrolled in this study may later participate in the HSK31858 clinical trial, where they will receive treatment as part of the trial protocol. After the unblinding of the trial, the study will analyze the relationship between sputum inflammation phenotypes and clinical outcomes, including treatment response and prognosis. The goal is to develop a clinical prediction model that incorporates inflammation subtypes to better predict patient outcomes in bronchiectasis.
