摘　　要：目的探讨参附注射液辅助治疗对急性心肌梗死(AMI)大鼠NOD样受体蛋白3(NLRP3)/半胱氨酸天冬氨酸特异性蛋白酶1(Caspase-1)介导的细胞焦亡信号通路以及炎性因子水平的影响。方法40只大鼠随机分为假手术组、模型组、倍他乐克组(0.9 mg/kg)和联合组(倍他乐克0.9 mg/kg联合参附注射液6 mL/kg),每组10只,连续灌胃3周。检测造模前、造模后和治疗3周时大鼠血清肌钙蛋白I(cTnI)、肌酸激酶同工酶(CK-MB)、白细胞介素(IL)-6、IL-1β和肿瘤坏死因子-α(TNF-α)水平。造模后和治疗3周时,比较各组大鼠左心室射血分数(LVEF)、左心室收缩末期内径(LVESD)、左心室舒张末期内径(LVEDD)等心脏彩超参数以及心肌梗死面积。应用实时荧光定量聚合酶链式反应(qRT-PCR)及Western blot检测心肌梗死面积NLRP3、Caspase-1的mRNA及其蛋白表达水平。结果与假手术组相比,模型组造模后和治疗3周时cTnI、CK-MB、IL-6、IL-1β、TNF-α、心肌梗死面积、NLRP3 mRNA和Caspase-1 mRNA表达量均升高,差异有统计学意义(P<0.05);与模型组相比,倍他乐克组和联合组治疗3周时cTnI、CK-MB、IL-6、IL-1β、TNF-α、心肌梗死面积、NLRP3 mRNA和Caspase-1 mRNA表达量均降低,且联合组上述指标均低于倍他乐克组,差异有统计学意义(P<0.05)。结论参附注射液辅助治疗AMI能够进一步减轻心肌细胞损伤,缩小梗死面积,抑制炎症反应和细胞焦亡活性。Objective To investigate the effect of adjuvant therapy of Shenfu Injection on NOD-like receptor protein 3(NLRP3)/cysteine-aspartic acid-specific protease 1(Caspase-1)mediated pyroptosis signaling pathway and inflammatory factor levels in rats with acute myocardial infarction(AMI).Methods A total of 40 rats were randomly divided into sham operation group,model group,betaloc group(0.9 mg/kg),and combination group(0.9 mg/kg betaloc combined with 6 mL/kg Shenfu Injection),with 10 rats in each group.The rats were treated by gavage continuously for 3 weeks.The levels of serum troponin I(cTnI),creatine kinase-MB(CK-MB),interleukin(IL)-6,IL-1β,and tumor necrosis factor-α(TNF-α)in rats were detected before modeling,after modeling,and at 3 weeks of treatment.Echocardiographic parameters such as left ventricular ejection fraction(LVEF),left ventricular end-systolic diameter(LVESD),left ventricular end-diastolic diameter(LVEDD),and myocardial infarction area were compared among groups after modeling and at 3 weeks of treatment.Real-time fluorescence quantitative polymerase chain reaction(qRT-PCR)and Western blot were used to detect the mRNA and protein expression levels of NLRP3 and Caspase-1 in the myocardium.Results Compared with the sham operation group,the levels of cTnI,CK-MB,IL-6,IL-1β,TNF-α,myocardial infarction area,and the expressions of NLRP3 mRNA and Caspase-1 mRNA in the model group were significantly increased after modeling and at 3 weeks of treatment(P<0.05);compared with the model group,the levels of cTnI,CK-MB,IL-6,IL-1β,TNF-α,myocardial infarction area,and the expressions of NLRP3 mRNA and Caspase-1 mRNA in the betaloc group and the combination group were significantly decreased at 3 weeks of treatment,and the above indicators in the combination group were significantly lower than those in the betaloc group(P<0.05).Conclusion Adjuvant therapy of Shenfu Injection for AMI can further alleviate myocardial cell injury,shorten infarction size,and inhibit inflammatory response and pyroptosis activity.
