ABSTRACT
<p><b>OBJECTIVE</b>To assess the effect of Tongxinluo on cytokines and myocardial no-reflow in early reperfusion of acute myocardial infarction (AMI).</p><p><b>METHODS</b>Forty mini-swine were divided into five groups randomly, sham group, control group, low dose (0.1 g/kg), medium dose (0.2 g/kg) and high dose (0. 4 g/kg) group of Tongxinluo (which were administered 2 h before reperfusion), eight swine in each group. Animals except those in the sham group were subjected to 1.5 h of coronary occlusion followed by 3 h of reperfusion. Serum contents of P-selectin, intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), interleukin 6 (IL-6) and interleukin 10 (IL-10), as well as myocardial contrast echocardiography (MCE) were evaluated at baseline, and after 1.5 h of AMI and 3 h of reperfusion.</p><p><b>RESULTS</b>(1) Compared with that of the control group, high dose of Tongxinluo could reduce serum contents of P-selectin and ICAM-1 at 1.5 h of AMI (all P<0.05), and P-selectin, ICAM-1, VCAM-1, and IL-6 at 3 h of reperfusion significantly (all P< 0.05), accompanied by significantly elevated IL-10 (P<0.05). (2) Compared with that of control group, high dose of Tongxinluo could reduce no-reflow area at 3 h of reperfusion significantly [(6.59 +/- 1.73) cm2 vs (4.68 +/- 1.53) cm2, P<0.05].</p><p><b>CONCLUSION</b>High dose of Tongxinluo could effectively reduce serum contents of adhesion and pro-inflammatory cytokines, regulate anti-inflammatory factor levels, and attenuate no-reflow area in the early reperfusion of AMI. It thus provided experimental basis for its clinical application.</p>
