S1-S11 represented the eleven KYQG samples.
Cell viability in HOK after treatment with CSE, Dex, NP, KYQG (the original formula) and eleven KYQG samples (S1-S11) for 24 hours.
CSE: cigarette smoke extract; Dex: Dexamethasone; NP: Niuhuangjiedu Pian; KYQG: Kouyanqing Granule.
The cell viability of control group was defined as 100%. *P < 0.05 and **P < 0.01 vs. control group.
