YQHX improved cardiac function and increased PGC-1α protein expression in rats MI model. a YQHX and TMZ improved cardiac function and attenuated cardiac remodeling in rats MI model. b YQHX and TMZ improved cardiomyocyte architectures in rats MI model. Scale bars = 50 μm. c Effects of YQHX and TMZ on PGC-1α protein expression in vivo. Values were represented as mean ± SD (n = 8). ^**P < 0.01, ^***P < 0.001 versus Sham; ^#P < 0.05, ^##P < 0.01, ^###P < 0.001 versus MI
