髓清丸对小鼠肝癌转移的影响

Effect of Suiqing Pill on Hepatic Carcinomatous Metastasis in Mice

[目的]观察活血化瘀中药复方髓清丸对肿瘤生长和转移的影响。[方法]C57BL/6小鼠60只,随机分为模型组,髓清丸高、低剂量组(36g/kg、18g/kg),以腹水型肝癌(H22)瘤株在小鼠右下肢爪垫内侧皮下接种,复制小鼠肝癌H22转移模型,观察小鼠实体瘤的瘤质量抑瘤率、肺部转移率、淋巴结转移情况、小鼠生存时间、生命延长率等指标的变化。[结果]髓清丸低剂量组的瘤质量较模型组减少(P<0.05),抑瘤率达到36.83％;模型组肺部转移率达100％,髓清丸高、低剂量组的肺部转移结节均较模型组减少,转移率较模型组低(P<0.05或P<0.01);髓清丸高、低剂量组同侧(?)窝、髂动脉旁淋巴结质量均较模型组减小(P<0.05);髓清丸高、低剂量组小鼠生命延长率分别为37.77％、36.77％,但生存时间与模型组比较未见显著性差异。[结论]髓清丸对H22肿瘤有一定的抑制和抗转移作用。

[Objective] To investigate the effect of Suiqing Pill (SP), a Chinese prescription with the actions of activating blood and removing blood-stasis, on growth and metastasis of tumor. [Methods] Sixty C57BL/6 mice were randomized to three groups: group A (model control), group B (low-dose SP) and group C (high-dose SP). H22 hepatocarcinomatous metastasis models were established by subcutaneous injection of H22 hepatocarcinoma cells into the right lower limb. The inhibitory rate of tumor weight, incidence of metastatic carcinoma of lung, metastasis of lymph node, survival time and life-span prolongation rate were observed. [Results] The weight of tumor was reduced and the inhibitory rate of tumor weight was 36.83% in group B (P < 0.05 compared with group A); incidence of metastatic carcinoma of lung was 100% in group A and metastatic nodules of lung were decreased in groups B and C (P < 0.05 or P < 0.01 compared with group A); lymph node weight in homolateral popliteal fossa and iliac periartery was lighter in group B and C than that of group A (P < 0.05); life-span prolongation rate was 37 .77% and 36.77% in groups B and C respectively and survival time did not differ much from that of group A. [Conclusion] SP has an inhibitory effect on the growth and metastasis of H22 tumor.
