目的探讨芪苈强心胶囊治疗压力超负荷心力衰竭的可能机制。方法随机取SD大鼠15只为假手术组
采用升主动脉缩窄术建立压力超负荷心力衰竭大鼠模型
75只造模成功大鼠随机分为模型组、卡托普利组和芪苈强心高、中、低剂量组各15只。卡托普利组给予卡托普利片6.25mg/(kg·d)
芪苈强心高、中、低剂量组分别给予芪苈强心胶囊1.0、0.5、0.25g/(kg·d)
假手术组和模型组灌服等体积的0.5%羧甲基纤维素钠
各组连续灌胃6周。透射电镜观察心肌组织毛细血管超微结构
比较各组大鼠心肌组织三磷酸腺苷(ATP)、二磷酸腺苷(ADP)、一磷酸腺苷(AMP)含量
血管黏附因子1(ICAM-1)与内皮型一氧化氮合酶(eNOS)mRNA表达水平
AMP激活的蛋白激酶(AMPK)及其磷酸化AMPK(p-AMPK)蛋白表达。结果芪苈强心低、中剂量组及卡托普利组均显著增加心肌组织中ATP含量(P<0.01)
各给药组ADP明显升高(P<0.01);芪苈强心高剂量组与卡托普利组ICAM-1mRNA表达降低、eNOSmRNA升高(P<0.05或P<0.01);芪苈强心低、中、高剂量组与卡托普利组p-AMPK蛋白表达均显著升高(P<0.05或P<0.01);各组大鼠心肌组织AMPK蛋白表达量差异无统计学意义(P>0.05)。结论芪苈强心具有保护压力超负荷大鼠心肌毛细血管内皮的作用
同时提高心脏能量负荷水平、改善能量代谢
其作用机制可能与激活AMPK-eNOS通路有关。
Objective To study the effect and possible mechanism of Qili Heart-Strengthening Capsule [heart-strengthening capsule of Huangqi (Radix Astragali) and Tinglizi (Semen Lepidii)] on pressure overload heart failure. Methods Fifteen SD rats were randomly selected as the sham operation group. The ascending aorta constriction was conducted to establish the pressure overload heart failure models. Totally 75 successfully modeling rats were randomized into the model group
captopril group
Qili Heart-Strengthening Capsule high-dose
middle-dose and low-dose groups
with 15 in each. The captopril group was given 6.25 mg/(kg·d) captopril tablet. The Qili Heart-Strengthening Capsule high-dose
middle-dose and low-dose groups were given 1.0
0.5 and 0.25 g/(kg·d) Qili Heart-Strengthening Capsule respectively. The sham operation group and model group were given an equal volume of 0.5% sodium carboxymethyl cellulose. The administration lasted for 6 weeks. The ultrastructure of myocardial tissue capillaries was observed by transmission electron microscopy. The adenosine triphosphate (ATP)
adenosine diphosphate (ADP)
adenosine monophosphate (AMP)
intercellular adhesion molecule-1 (ICAM-1)
endothelial nitric oxide synthase (eNOS) mRNA expression
AMP-activated protein kinase (AMPK) and phosphorylated AMPK (p-AMPK) protein in the myocardial tissue was compared. Results The ATP contents in the Qili Heart-Strengthening Capsule middle-dose and low-dose groups and captopril group were significantly increased (P<0.01). The ADP contents in all medication groups were significantly increased (P<0.01). The ICAM-1mRNA expression was significantly decreased but the eNOS mRNA expression was significantly increased in the Qili Heart-Strengthening Capsule high-dose group and captopril group (P<0.05 or P<0.01). The p-AMPK expression was significantly increased in the Qili Heart-Strengthening Capsule groups and captopril group (P<0.05 or P<0.01). There was no significant difference between before and after treatment in the AMPK expression in all groups (P>0.05). Conclusion Qili Heart-Strengthening Capsule can protect the myocardial capillary endothelial
increase the cardiac energy load level
improve the energy metabolism
and its mechanism may be related to the activation of AMPK-eNOS pathway.
