QSYQ inhibited expressions of COXs. a Western blot showed that expressions of COX1 and COX2 in cardiac tissues were significantly up-regulated in the model group compared with those in the sham group. In the aspirin and QSYQ-treated groups, expressions of COX1 and COX2 were all down-regulated compared with those in the model group. The inhibitory effect of QSYQ on COXs was milder than that of aspirin. b Expression of cardiac PGE2 in the model heart tissues was up-regulated as compared with that in the sham group and treatments with aspirin and QSYQ down-regulated expression of PGE2 towards basal level. Figure (c) and (d) were the relative quantitative illustrations of expressions of COX1 and COX2 in different groups (*P < 0.05, **P < 0.01, ***P < 0.001, other groups vs. model group, n = 8)
