TNNT2 and myocardial infarction: Figure 3(F, G) also shows that XBW could decrease the level of cTnI and cTnT in the heart tissue from 1.047 ± 0.061 to 0.808 ± 0.078 ng/g (p < 0.05) and from 2.166 ± 0.111 to 1.868 ± 0.092 ng/g (p < 0.05). Echocardiography in Figure 3(H) exhibited that XBW improved cardiac function. H&E staining showed that XBW administration attenuated inflammatory cell infiltration, and disordered myocardial fibre induced by MI/RI (Figure 3(I)). In in vitro study, XBW protected H9c2 cell against OGD/R injury from 40.08% to 58.8%, 77.9%, 80.1% at 60, 240 and 720 μg/mL, respectively (Figure 4(A,B)).
