a The proliferation curve of HepG2 cells in different groups; (b) The intensity and statistical distinctions of AO/PI staining of HepG2 cells after 24 h; and (c) 48 h treatments. (AO/PI: acridine orange/propidium iodide; live cells, green fluorescence; dead cells, red fluorescence). Statistical analysis is performed by Student’s t test (t-test). *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.001. d The photograph of crystal violet staining after 0, 24, 48, and 72 hours in different treatments. e The fluorescence microscopy of AO/PI staining (live cells, green fluorescence; dead cells, red fluorescence) contained HepG2 cells after treatments. The scale bars are 200 μm
