objective: To investigate effects of buyang huanwu decoction (BYHWD) on the rats' myocardial hypertrophic model induced by abdominal aortic constriction, and to clarify the molecular regulatory mechanisms for sarcoplasmic reticulum calcium uptake.

Methods

Hypertrophic myocardium rat model was induced by abdominal aorta constriction (AAC). Four weeks after modeling, rats were randomly divided into the sham-operation group (Group S), the AAC model group (Group M), the Enalapril group (Group E), and the BYHWD treatment group (Group BYHWD), respectively. The left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), + dp/dtmax,-dp/dtmax, cardiac output (CO), heart mass index (HMI), and left ventricular mass index (LVMI) were observed in each group after 12-week medication. The serum contents of the atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were detected using ELISA. The SERCA2a activity, the ex-pressions of SERCA2a, phospholamban (PLN), and PLN phosphorylation were observed finally.

Results

Compared with Group S, LVSP and LVEDP significantly increased,-dp/dtmax and CO obviously decreased, the myocardial tissue was obviously thickened, the serum contents of ANP and BNP increased, the activity and expression of SERCA2a decreased, the SERCA2a/PLN ratio and PLN phosphorylation degree decreased in Group M (all P <0.05). Compared with Group M, LVEDP obviously decreased, -dp/dtmax and CO obviously increased, the hypertrophy myocardial tissue was obviously lessened, the serum contents of ANP and BNP decreased, the activity of SERCA2a increased, the relative expression contents of SERCA2a, Ser16, and Thrl7 were elevated in Group BYHWD (all P <0.05). BYHWD had significant roles in elevating the SERCA2a/PLN ratio and PLN phosphorylation degree (P <0.05).

Conclusion

BYHWD could significantly improve hemodynamics of heart failure rats, elevate CO, lessen cardiac hypertrophy, and improve the capabilities for sarcoplasmic reticulum calcium uptake."xsd:string
