Multicenter Human Derivatives Prospective Cohort Study: Clinical information will be collected from patients with ankylosing spondylitis and their families who have provided research consent. And clinical samples including blood, saliva, feces, and mucosal biopsy tissue (from patients scheduled for sigmoid colonoscopy or routine colonoscopy examinations) will be collected. Multi-omics data production and laboratory analysis will be conducted using the collected samples, followed by integrated bioinformatic analysis using the produced data."
