As shown in Figure 5D, Ki67 positive ratio in 30 mg/kg Tan‐I group significantly inhibited compared with control group (P < .05), Caspase‐3‐positive cells and tumour apoptosis index in 30 mg/kg Tan‐I group significantly enhanced than that of control group (P < .05) (Figure 5D and E). This evidence concerns the gene MKI67 and neoplasm.
