Methods: Effect of RSM on SMMC 7721 cell membrane intercellular adhesive molecule 1 (ICAM 1) expression was observed by immunofluorescence flow cytometry; effect on invasive ability and of SMMC 7721 cell and the detachment of which attached to fibronectin (FN) by cell migration experiment; effect on adhesion of SMMC 7721 cell with FN by MTT method and effect on adhesion between 7721 7721, 7721 lymphocyte and 7721 endothelial cell by cell adhesion experiment. LCI D20 human liver cancer metastasis model, after hepatectomy, was used to observe the effect of RSM on recurrence and metastasis of liver carcinoma in nude mice. Results: ICAM 1 expression in SMMC 7721 cells incubated with RSM was significantly lower than that in cells did not treated with RSM. RSM could inhibit the invasive ability of SMMC 7721 cell and made the cells already attached to FN exfoliated. It could also inhibit the adhesion of 7721 7721, 7721 lymphocyte and 7721 endothelial cell. And RSM showed preventive and therapeutic effect on intrahepatic and remote metastasis/recurrence of early and late human post hepatectomy liver cancer in nude mice. Conclusion: RSM could inhibit the invasion and adhesion of SMMC 7721 cell and could also prevent and inhibit metastasis and recurrence of human liver cancer after hepatectomy in nude mice.展开更多
