Gout inflammation indexes of mice in the four groups. Representative images of foot joint (a) and H&E stained histological (b); IL-1β (c); IL-6 (d); TNF-α (e); MPO activity (f). CT: control group; HFD: hyperuricaemia model; MSU: acute gout model; CGM: compound gout model. “ns” represents not significant; “*” represents p < 0.05 in comparison with CT; and “**” represents p < 0.01 in comparison with CT; “+” represents p < 0.05 in comparison with CGM; and “++” represents p < 0.01 in comparison with CGM
