Effect of SE on cell viability and cell death on HK-2 cells induced by H/R. The viability was checked by Cell Counting Kit-8 (CCK-8); cell death was analyzed by Annexin V and propidium iodide (PI) with staining being followed by flow cytometry; ∗P < 0.05, ∗∗P < 0.01 versus the control group. SE (Rhubarb, Astragalus radix, Salvia miltiorrhiza, and Safflower).
