目的
2
基于巨噬细胞迁移抑制因子(MIF)/腺苷一磷酸活化的蛋白激酶(AMPK)信号通路探讨盐酸戊乙奎醚(PHC)对小鼠心肌缺血再灌注(I/R)损伤的保护作用及潜在机制。
方法
2
将雄性C57BL/6小鼠随机分为假手术组、I/R组、I/R+PHC组(PHC 20 μg/kg)、I/R+ISO-1组(MIF抑制剂35 mg/kg)、I/R+PHC+ ISO-1组(剂量同各单药组),每组8只。除假手术组外,其余各组均采用冠状动脉结扎法制备I/R损伤模型。于结扎前30 min,各药物组小鼠分别单次尾静脉注射相应药液1 mL。于再灌注120 min后,检测各组小鼠的心功能指标[心率、每搏输出量、射血分数、心输出量、收缩期末左室后壁厚度(LVPWs)、舒张期末左室后壁厚度(LVPWd)]和血清中炎症因子[白细胞介素6(IL-6)、IL-10、肿瘤坏死因子α(TNF-α)]水平,观察其心肌组织病理改变和超微结构,并检测心肌组织中B细胞淋巴瘤2(Bcl-2)、磷酸化AMPKα(p-AMPKα)、MIF蛋白的表达水平。
结果
2
与假手术组比较,I/R组小鼠心肌细胞排列松散,炎症细胞浸润严重,线粒体受损明显,其血清中IL-6、TNF-α水平和心肌组织中p-AMPKα蛋白的表达均显著升高或上调,心率、每搏输出量、射血分数、心输出量、LVPWd和血清中IL-10水平均显著降低(
P
<0.05);与I/R组比较,I/R+PHC组小鼠心肌组织病变有所减轻,其血清中IL-6、TNF-α水平均显著降低,心率、每搏输出量、射血分数、心输出量、LVPWs、LVPWd、血清中IL-10水平以及心肌组织中Bcl-2、p-AMPKα、MIF蛋白的表达均显著升高或上调(
P
<0.05);而I/R+ISO-1组小鼠心肌组织病变有所加重,多数定量指标显著恶化(
P
<0.05);MIF抑制剂能普遍逆转PHC对I/R小鼠的保护作用(
P
<0.05)。
结论
2
PHC可改善I/R小鼠心功能,减轻其心肌组织炎症,恢复其心肌组织超微结构,上述作用可能与激活MIF/AMPK信号通路有关。
OBJECTIVE
2
To investigate the protective effects and potential mechanism of penehyclidine hydrochloride (PHC) on myocardial ischemia-reperfusion (I/R) injury in mice through the macrophage migration inhibitory factor (MIF)/adenosine monophosphate-activated protein kinase (AMPK) signaling pathways.
METHODS
2
Male C57BL/6 mice were randomly divided into sham operation group, I/R group, I/R+PHC group (PHC 20 μg/kg), I/R+ISO-1 group (MIF inhibitor 35 mg/kg), I/R+PHC+ISO-1 group (with the same dosage as each single drug group), with 8 mice in each group. Except for the sham operation group, the myocardial I/R injury model was prepared by coronary artery ligation. Thirty minutes before ligation, mice in each drug group were injected with 1 mL of the corresponding drug solution through the tail vein. After 120 min of reperfusion, the levels of cardiac function indexes [heart rate, stroke volume, ejection fraction, cardiac output, left ventricular posterior wall thickness in systole (LVPWs), left ventricular posterior wall thickness in diastole (LVPWd)], serum inflammatory factors [interleukin-6 (IL-6), IL-10, tumor necrosis factor-α (TNF-α)] in mice were detected in each group; the pathological changes and ultrastructure of myocardial tissue were observed, and the protein expressions of B cell lymphoma-2 (Bcl-2), phosphorylated AMPKα (p-AMPKα) and MIF in myocardial tissue were detected.
RESULTS
2
Compared with the sham operation group, the myocardial cells in the I/R group were loosely arranged, with severe infiltration of inflammatory cells and obvious mitochondrial damage. Serum levels of IL-6 and TNF-α and protein expression of p-AMPKα in myocardial tissue were significantly increased or upregulated, while heart rate, stroke volume, ejection fraction, cardiac output, LVPWd and serum level of IL-10 were significantly decreased (
P
<0.05). Compared with the I/R group, the myocardial tissue lesions in the I/R+PHC group were alleviated; serum levels of IL-6 and TNF-α were decreased significantly, while heart rate, stroke volume, ejection fraction, cardiac output, LVPWs, LVPWd, serum level of IL-10, and protein expressions of Bcl-2, p-AMPKα and MIF in myocardial tissue were significantly increased or upregulated (
P
<0.05). However, myocardial tissue lesions of mice in the I/R+ISO-1 group worsened, with most quantitative indicators significantly deteriorating (
P
<0.05); MIF inhibitor could generally reverse the protective effect of PHC on I/R mice (
P
<0.05).
CONCLUSIONS
2
PHC can improve cardiac function, reduce myocardial inflammation, and restore the ultrastructure of myocardial tissue in I/R mice. These effects may be related to the activation of the MIF/AMPK signaling pathway.
