Bioinformatics-based screening and experimental validation of biomarkers for the treatment of connective tissue-associated interstitial lung disease with liquorice and dried ginger soup

CXCL8, IL1A, IL1B, NFE2L2, and PTGS2 are critical CTD-ILD biomarkers. Licorice ginger soup may target these genes via quercetin, providing novel diagnostic and therapeutic insights.
