40只雄性SD大鼠随机选取10只为假手术组,其余行左冠状动脉前降支结扎术构建慢性心力衰竭(CHF)大鼠模型,造模完成后随机分为模型组、卡托普利组和益气活血组,每组10只。给药组分别予以卡托普利片13.5 mg·kg

结论:
2
益气活血方可有效减轻慢性心力衰竭大鼠心室重构、改善线粒体能量代谢,其机制可能与抑制Wnt/

Objective:
2
To observe the intervention effect of Yiqi Huoxue recipe (YQHX) on ventricular remodeling in rats with chronic heart failure
in order to explore its mechanism.
Method:
2
Among 40 male SD rats
10 were randomly selected as the sham operation group. The left anterior descending coronary artery ligation was performed to construct the chronic heart failure(CHF) rat model. After modeling
they were randomly divided into model group
captopril group(13.5 mg·kg
-1
·d
-1
) and YQHX group (20 g·kg
-1
·d
-1
)
and orally given the corresponding drugs. After 8 weeks of intervention
cardiac tissues were collected
body mass and heart mass were weighed
and echocardiography were performed to detect the changes in cardiac structure. Masson staining was performed to determine the myocardial interstitial collagen volume fraction. Western blot was used to detect the expression levels of mitochondrial fusion protein optic atrophy 1 (Opa1) and cleavage protein dynamic-related protein 1 (Drpl). The quantitative real-time fluorescence polymerase chain reaction(Real-time PCR)was applied to detect the expressions of Wnt/
β
-catenin pathway-related factors such as lipoprotein receptor-related protein 6 (LRP6)
glycogen synthase kinase-3
β
(GSK-3
β
) and
β
-catenin.
Result:
2
Compared with the sham group
the left ventricular wall of the model group was significantly thickened (
P
<
0.05)
the cardiac cavity was significantly enlarged
and the content of collagen in the myocardial interstitium was increased (
P
<
0.01). The expression level of Opal decreased
the expression level of Drp1 increased (
P
<
0.05)
the mRNA expression level of LRP6
GSK-3
and
β
-catenin increased (
P
<
0.01). Compared with the model group
YQHX group can reduce ventricular wall thickening
heart chamber enlargement
myocardial interstitial collagen content
up-regulate the low expression of Opa1
but down-regulate the high expressions of Drpl
LRP6
GSK-3
β
β
-catenin(
P
<
0.05
P
<
0.01).
Conclusion:
2
YQHX can effectively alleviate ventricular remodeling and improve mitochondrial energy metabolism in rats with CHF. The mechanism may be related to the inhibition of Wnt/
β
-catenin related factors.
