Methods： A rat model of hepatic carcinoma was established. The serum samples of hepatic carcinoma and normal rats were analyzed via SELDI-TOF-MS Technology. The changes of the serum protein fingerprint patterns were observed between the experimental group of hepatic carcinoma and the controls. The analysis was conducted by statistical software-Biomarker Wizard. Results： Fifty-six protein peaks in the serums were found. Within m/z 0-20 000, the protein peaks of rrdz 1158, 8 835 and 15 302 of hepatic carcinoma serums were obviously higher in the rat models compared with those in the controls（P 〈 0.01）. Conclusion： Three peaks were considered as potential biomarkers according to the serum protein fingerprint patterns of the hepatic carcinoma group and the control group.展开更多
