Modified Sini Powder (MSNP) improves depressive symptoms in postoperative NSCLC patients with mild-to-moderate depression

This protocol describes a multicenter, randomized, double-blind, placebo-controlled trial evaluating MSNP for postoperative depression in NSCLC patients. The primary outcome is a ≥25% reduction in the 17-item Hamilton Depression Rating Scale score after 6 weeks of treatment. The trial aims to provide robust clinical evidence and explore multi-omics mechanisms.
