Cardiac function was detected by echocardiography. Normal cardiac function was found in sham-operated group including LVEDd, LVEDs, LVEF and LVFS. Down-regulation of cardiac function appeared in model group rats. DQP can significantly up-regulate the EF and FS, and reduced the LVEDs. ^▲▲P < 0.01, vs sham- operated group; ^*P < 0.05, ^**P < 0.01, vs model group.
