| Objective: To observe the clinical effects of supermicro-bletilla striata powder mixture on the embolization of primary hepatocellular carcinoma. Method: 66cases with PHC were randomly divided into two groups: Test group and control group.Test group included 36 cases treated with mixture of supermicro-bletilla striata powder plus hydroxyl camptothecinum and iodine oil, control group included 30 cases with hydroxyl camptothecinum and iodine oil .all the patients were operated with TACE under DSA. To observe the decreased ratio of tumour, recent effects, toxication and side effects and survival condition(postoperative survival rate in 3,6,12 and 24month, respectively). Results: Decreased rat of tumor in test group were 36.1±2.3%,55.5±4.5% and 72.2±3.4% after 3, 6,and12 month respectively, distinguished with that in control group. Postoperative survival rate of test group were 97.2 % ,91.6%,80.5% and 44.4% in 3,6,12,and 24 month respectively,remarkably different from that of control group. The side effects and toxications of two groups were no difference. Conclusion: Supermicro –bletilla striata powder mixture as embolism reagent used in TACE could reduced the reccurence and transfusion of tumor, remarkeably increase the survival rate.
