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.

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 investigate the effect oflamotrigine (LTG) on repair ofhemisection of spinal cord in mice models.Methods A total of 80 female C57BL/6 mice were employed to establish the models of spinal cord hemisection,and randomly divided into 3 groups:spinal cord injury (SCI) group (n=27),SCI+LTG group (n=26) and SCI+0.9％ saline group (n=26);mice in SCI+LTG group were given intraperitoneal injection oflamotrigine (25 mg/kg) for a consecutive 7 d,and mice in the SCI+0.9％ saline group were given the same volume of 0.9％ saline.Basso,Beatti,Bresnahan (BBB) scale was performed 1,7 and 14 d after SCI;6 mice in each group were sacrificed 1,7 and 14 d after SCI,and glial fiber acidic protein (GFAP) and ionized calcium-binding adaptor molecule 1 (Iba1)-positive cells were observed by immunofluorescence and the expressions of inflammatory factors interleukin (IL)-1,IL-10 and tumor necrosis factor (TNF-α) were observed by ELISA.Results On the 7th and 14th d of injury,the BBB scale scores in the SCI+LTG group were significantly higher than those in the SCI group and SCI+0.9％ saline group (7 d:5.1667±0.40825,4.0000±0.63246 and3.8333±0.40825;14 d:6.5000± 0.5477,5.5000±0.5477 and 5.3333±0.5164,P＜0.05).On the 7th and 14th d of injury,less percentage of GFAP positive ftuorenscent area and fewer number of Iba1 positive cells in the SCI+LTG group were noted than those in the SCI group and SCI+0.9％ saline group (P＜0.05).On the 7th d of SCI,the IL-1 and IL-10 expressions in the SCI+LTG group were obviously lower than those in the SCI group and SCI+ 0.9％ saline group (P＜0.05).Conclusion Lamotrigine improves the motor function after SCI by decreasing the secretion of inflammatory factors and activation of glial cells.
