ABSTRACT
OBJECTIVE@#To investigate the mechanism of electroacupuncture (EA) with the involvement of sarcoplasmic reticulum Ca@*METHODS@#Thirty SPF-ranked SD rats were randomly divided into a control group, a model group, an EA group, an aconitine group and an EA plus aconitine group, with 6 rats in each group. The rat model of acute heart failure was established by infusion of high-dose propranolol hydrochloride solution into the right femoral vein. After stabilized for 10 min in the modeled rats, EA was exerted at "Neiguan" (PC 6), with disperse-dense wave, 2 Hz/15 Hz in frequency, 3 mA in intensity, for 30 min in the EA group and the EA plus aconitine group; aconitine solution (10 μg/kg) was injected from the left femoral veins in the rats in the aconitine group and the EA plus aconitine group. Hemodynamic indexes such as the left ventricular systolic pressure (LVSP) and the maximum rate of increase/decrease of left ventricular pressure (±dp/dt@*RESULTS@#Compared with the control group, LVSP and ±dp/dt@*CONCLUSION@#The intervention with electroacupuncture achieves the synergism/ attenuation effect of aconitine for the improvements in heart failure probably by up-regulating the expression of SERCA2a and down-regulating the expression of PLB in myocardial tissue.
