CP and neoplasm: Figure 1(a) shows that both CP treatment and CP plus HQQD treatment inhibited the tumor growth compared with control group (p < 0.001). HQQD-H combined with CP was more effective in reducing the tumor growth compared with HQQD-M and HQQD-L, or CP alone. As shown in Figure 1(b), CP inhibition rate was 87.11 percent compared with control group; the inhibition rate for CP combined with HQQD-H was 87.16 percent.
