RESUMO

Objective To detect the tissue factor (TF) mRNA expression in hepatocellular carcinoma and to elucidate its significance. Methods TF mRNA was detected by reverse transcription-polymerase chain reaction (RT-PCR) in 27 cases of human hepatocellular carcinoma tissue specimen with their adjacent tissues and in 27 non-tumorous process tissues. Then the relationship between mRNA expression and pathological data were analyzed. Results The expression and the relative expression intensity of TF in hepatocellular carcinoma tissues were 62.96(17/27) and 0.567?0.268 respectively, which were significantly higher than those in their adjacent tissues 〔33.33(9/27), 0.469?0.184〕 and in 27 non-tumorous process tissue 〔29.63(8/27), 0.353?0.121〕, P0.05). Conclusion Expression of TF mRNA were significantly higher in hepatocellular carcinoma and in the invasive and metastatic tissue, which indicated that TF may play an important role in carcinogenesis, invasion and metastasis of hepatocellular carcinoma.

RESUMO

Objective To study the effects of staphylococcal enterotoxin B(SEB) on the proliferation of tumor infiltrating lymphocytes(TILs) from rectum adenocacinoma.Methods The TILs from patients with rectum adenocacinoma were stimulated with SEB and interleukin 2(IL-2) respectively,and then the proliferation of TILs,the secretion of IL-2 and tumor necrosis factor-?(TNF-?) were determined.Results SEB presented profound stimulating effect on the TILs from rectum adenocarcinoma both the proliferation of TILs and the secretion of cytokines.Compared with the IL-2,SEB stimulated TILs more quickly,and SEB acted more effectively in the early stage but weakly in the late stage.Conclution SEB was an effective TIL stimulator.

RESUMO

AIM: To detect the mRNA expression of tissue factor (TF), urokinase-type plasminogen activator (u-PA) and urokinase-type plasminogen activator receptor (u-PAR) in the samples of hepatocellular carcinoma (HCC) and adjacent tissue, and to elucidate their association with clinical significance. METHODS: The mRNA levels of TF, u-PA and u-PAR in 27 human HCC tissue samples with their adjacent tissue samples and 27 normal liver tissues were detected by RT-PCR. The relationship between the mRNA expression and their clinic-pathological data were also analyzed. RESULTS: The expressive rate of TF, uPA and uPAR in HCC tissue samples was 62.96% (17/27), 70.37% (19/27), 77.78% (21/27), respectively and relative expression intensity of TF, uPA and uPAR were 0.567?0.268, 0.964?0.458 and 0.784?0.322, respectively, which were significantly higher than those in adjacent tissue group and normal liver group (P

RESUMO

AIM:To detect tissue factor(TF)level both in plasma and in tissue of hepatocellular carcinoma(HCC)patients and to elucidate their association with clinical features.METHODS:Plasma TF levels of 50 cases of HCC patients and 30 cases of control were detected by ELISA.27 HCC tissue samples with their adjacent tissue samples and 27 normal liver tissues were detected by RT-PCR.RESULTS:① Plasma TF levels were increased significantly in HCC group when compared with control(P
