        ABSTRACT   OBJECTIVE:To investigate the effects of Shenfu yixin decoction on the utilization of fatty acid in primary hypoxic
        cardiomyocytes and its potential mechanism. METHODS:The apical tissue of neonatal SD rats with 1-3 days old were collected,
        and the primary cardiomyocytes were isolated,cultured and identified. The cardiomyocytes were randomly divided into normal
        group,model group,coenzyme Q10 group(positive control,1 × 10  - 4  mol/L),Shenfu yixin decoction low-dose and high-dose
        groups(0.25,0.5 mg/mL). Except for normal group,cells in other groups were cultured under 5%O2,5%CO2 and 90%N2 for 6
        hours to induce hypoxic injury model. After 6 hours of hypoxia,the content of ATP was detected by luciferase luminescence assay.
        Western blotting assay was adopted to detect the expression of FAT/CD36,PPAR α and PPAR β/δ. RESULTS:Compared with
        normal group,the content of ATP and relative expression of FAT/CD36 protein were decreased significantly in model group(P<
        0.05). Compared with model group,the content of ATP was increased significantly in coenzyme Q10 group and Shenfu yixin
        decoction high-dose group,while the relative expression of FAT/CD36 and PPARα protein in coenzyme Q10 group,the relative
        expression of FAT/CD36 protein in Shenfu yixin decoction high-dose group as well as the relative expression of PPARα and PPARβ/δ
        protein in Shenfu yixin decoction groups were decreased significantly(P<0.05). CONCLUSIONS:Shenfu yixin decoction can
        inhibit the utilization of fatty acid of primary hypoxic cardiomyocytes and improve their energy metabolism by inhibiting the
        expression of FAT/CD36,PPARα and PPARβ/δ protein.
