Objective To investigate the correlations of serum matrix metalloproteinase-2, -9 (MMP-2, MMP-9) contents and tissue expressions in hepatocellular carcinoma with tumor invasion and metastasis. Methods Serum MMP-2, MMP-9 contents were detected in 40 patient with hepatocellular carcinoma and 20 healthy controls by ELISA; the expressions and distributions of MMP-2 and MMP-9 in 40 patients and 10 normal tissues were detected by immunohistochemical method. Results Serum MMP-2, MMP-9 contents were significantly elevated in cancer samples compared with normal serum (P

Objective To investigate the expressions of CD40 and ICAM-1 in primary hepatocarcinoma and clinical significance and analyze their relationships with carcinogenesis and progression of liver cancer. Methods S-P immunohistochemistry was used to detect the expressions of CD40 and ICAM-1 in 40 cases of hepatocarcinoma and 25 cases of normal liver tissue (distance from cancer tissues≥2 cm).Results The positive expression rates of CD40 and ICAM-1 were 47.5% and 82.5% in liver cancer tissue,which was significantly higher than those in normal liver tissue (P0.05).The positive expression rate of ICAM-1 was associated with lymph node metastasis as well as histological grade(P
