丹参对肝癌转移复发防治作用的研究

Study on Preventive and Therapeutic Effect of Radix Salviae Miltiorrhizae on Recurrence and Metastasis of Liver Cancer

目的：观察丹参对ＳＭＭＣ－７７２１肝癌细胞株（７７２１细胞）侵袭粘附能力和对裸鼠人肝癌切除术后转移复发的影响。方法：以流式细胞仪测量丹参对７７２１细胞表面细胞间粘附分子１（ＩＣＡＭ１）的表达的影响。以细胞侵袭实验观察丹参对ＳＭＭＣ７７２１细胞侵袭运动能力及对已与纤维连接蛋白（ＦＮ）粘附的７７２１细胞脱落的影响。以ＭＴＴ法测量丹参对７７２１细胞与ＦＮ粘附的影响。以细胞粘附实验观察丹参对７７２１－７７２１细胞，７７２１－内皮细胞，７７２１－淋巴细胞之间粘附的影响。以ＬＣＩＤ２０裸鼠人肝癌转移模型为材料，观察丹参对早期和晚期肝癌切除术后转移复发的影响。结果：丹参处理的７７２１细胞ＩＣＡＭ１表达明显低于对照组，丹参可抑制７７２１细胞的侵袭能力，促进已粘附细胞的脱落，可抑制７７２１与７７２１细胞、淋巴细胞、内皮细胞的粘附，并对早期和晚期裸鼠人肝癌切除术后的肝内和远处转移复发有防治作用。结论：丹参可抑制ＳＭＭＣ－７７２１细胞的侵袭粘附能力，防治裸鼠人肝癌切除术后的转移复发。

Objective: To study the inhibitory effect of Radix Salviae Miltiorrhizae (RSM) on adhesive and invasive ability of SMMC 7721 liver cancer cells, and on the metastasis and recurrence on post hepatectomy liver cancer in nude mice. 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; effcet 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 cacer 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.
