METHODS： H9c2 cells were separately treated with FPI, Renshen injection （RSI） and SFI. Cell viability, lactate dehydrogenase （LDH） release, spontaneous beating rate of primative cardical cells, caspase-3/7 activity, cell apoptosis, and cytochrome P450 2J3 （CYP2J3） mRNA expression were analyzed. RESULTS： The viability of H9c2 cells treated with SFI （37 and 75 mg/mL） was significantly higher than that of H9c2 cells treated with FPI （25 and 50 mg/mL） （P〈0.05, P〈0.01, respectively）. LDH activity of H9c2 cells treated with SFI （75 mg/mL） was significantly decreased （P〈0.01） compared with that of H9c2 cells treated with FPI （50 mg/mL）. SFI （150 mg/mL） significantly attenuated FPI （100 mg/mL）-induced spontaneous beating rate decrease in primary myocardial cells after 4-hour treatment. Compared with FPI （12 and 25 mg/mL）, SFI （18 and 37 mg/mL） treatment could effectively reverse the change of caspase-3/7 activity （P〈0.01 and P〈0.01, respectively）. Compared with FPI （6 and 25 mg/mL）, apoptotic cells decreased significantly （P〈0.05, P〈0.01, respectively） when H9c2 cells were incubated with SFI （9 and 37 mg/mL）. The expression of CYP2J3 mRNA was down-regulated by FPI, while RSI and SFI could up-regulate the expression of CYP2J3 （P〈0.01）, which suggested the potential mechanism of protection of RSI against cardiac myocyte damage induced by FPI treatment. CONCLUSION： These observations indicate that SFI has the potential to exert cardioprotective effects against FPI toxicity. The effect was possibly correlated with the activation of CYP2J3.展开更多
