The mRNA and protein expressions of the TLR4/MyD88/NF‐κB‐P65 signalling pathway‐related genes in myocardium of rats in the sham, MI, LTS, HTS, LPS, T + LPS, LTS + LPS, and HTS + LPS groups. Notes: A, The mRNA expression of TLR4, MyD88 and NF‐κB‐P65 in rat myocardium; B, The protein expressions TLR4, MyD88 and NF‐κB‐P65 in the myocardium of rats; C, The expressions of TLR4, MyD88 and NF‐κB‐P65 by the analysis of grey values according to Figure 4B; *, compared with the sham group, P < .05; ^#, compared with the MI group, P < .05; ^&, compared with the LPS group, P < .05; TLR4, toll‐like receptor 4; myD88, Myeloid differentiation factor 88; NF‐κB‐P65, Nuclear Factor‐kappaB‐P65; MI, myocardial infarction; LTS, low‐dose tanshinone IIA; HTS, high‐dose tanshinone IIA; LPS, Lipopolysaccharide
