cur-hydrogel attenuated cardiomyocyte apoptosis induced by HR. a The effect of curcumin and cur-hydrogel on cell survival rate was evaluated by MTT. n = 5. b Apoptosis-related proteins were detected by western blot. n = 3, *p < 0.05; **p < 0.05. c Annexin V-FITC/PI apoptosis kit was used to detect cell apoptosis. n = 3, *p < 0.05; **p < 0.05. d TUNEL staining and statistical chart. (Bar = 150 μm) n = 5, *p < 0.05; **p < 0.05
