GZMB and chronic rhinosinusitis with nasal polyps: We used bacterial culture and immunohistochemistry to find that the positive rate of lipopolysaccharide (LPS) was much higher than that of Escherichia coli in chronic rhinosinusitis with nasal polyps (CRSwNP), and the LPS levels were positively correlated with glucocorticoid receptor‐β (GR‐β) expression in CRSwNP.
