The metastatic inhibitory rate in the DDP group and Rg3 group was 30.25%and 58.57%,respectively, which showed significan difference with the control group.great synergetic effect in decreaseing meta- static foci on lung surface.with.The expression of TAMs in the control group,cisplatin group and Rg3 group was(47.21±12.06),(45.67±11.90)and (16.11±6.32),respectively;and the expression of MVD were(24.57±
