Photographs of solid tumors (a) and their representative images of HE-stained sections. (b) from H1299 NSCLC bearing mice after the 6-week treatment trial. The tumors in the sample groups were much smaller than those in the control group. In the pathological sections of the control group, the tumor nuclei (dark purple) were large, while the tumor cells were apoptosis significantly in the sample group. ∗:P < 0.05, ∗∗:P < 0.01 of the tumor weight as compared to control group
