Objective To detect the expression of MAGE-A9 in human hepatocellular carcinoma (HCC), and to investigate the association between expression of MAGE-A9 and the clinicopathological characteristics of HCC.Methods Reverse transcription-polymerase chain reaction (RT-PCR), one-step quantitative-PCR (qPCR) and immunohistochemistry (IHC) methods were performed to characterize the expression of MAGE-A9 in HCC cell lines and tissues.Kaplan-Meier survival analysis and Cox regression were employed to evaluate the prognosis of 100 HCC patients.Results The expression of MAGE-A9 mRNA in HCC (4.44±0.342) was significantly higher than that in non-cancerous cells and tissues (1.73±0.178) (P ＜ 0.05).The expression level of the MAGE-A9 protein in HCC was related to the pathological grade (P =0.003), portal vein invasion (P =0.001), distant metastasis (P =0.022) and TNM stage (P =0.005).Cox regression analysis revealed that MAGE-A9 expression is an independent prognostic factor for disease-free survival (P =0.006) and overall survival (P =0.022).Conclusion MAGE-A9 is a valuable prognostic biomarker for HCC patients, and its high expression suggests unfavorable survival outcomes in HCC patients.

Objective To explore the mechanism of Huagan Jiedu decoction in treatment of chronic hepatitis B by testing the influence of the decoction on Serum IL-2, IL-4 and IFN-γ of rat models of chronic hepatic injury. Methods The model of Chronic hepatic injury was established by subcutaneously injecting 40% CCl4-olive oil solution in rats according to the ratio of 3ml per kg. of body weight. 60 healthy rats were divided randomly into a normal group, a model group, a low dose of Huagan Jiedu decoction group, a large dose of Huagan Jiedu decoction group, and a control group (Qingre Jiedu tablet group), 15 cases in each group. The Serum IL-2, IL-4 and IFN-γ were detected in each group separately. Results Compared with the normal group, the Serum IL-2 and IFN-γ were decreased (t=2.401, 2.337, P=0.0349, 0.0378) and the Serum IL-4 was increased (t=2.896, P=0.00861 ) in the model group; Compared with the model group, the Serum IL-2 and IFN-γ were increased (t=2.417, 2.344, P=0.0341, 0.0372, P＜0.05; t=3.114, 2.988, P=0.0052, 0.0068) in the large Huagan Jiedu decoction group and the control group, while the Serum IFN-γ was increased (t=3.049, P=0.0062) in the low dose of Huagan Jiedu decoction group and the Serum IL-4 was decreased (t=3.102, 3.017, 2.979, P=0.0061, 0.0065, 0.0069)in both Huagan Jiedu decoction groups and the control group. Conclusion Large dose of Huagan Jiedu decoction has sound therapeutic effects on rats with chronic hepatic injury by decreaseing the content of the Serum IL-4 and increasing IL-2 and IFN-γ, and adjusting th1/th2 balance.
