Objective To investigate the expressions of TRIM59,Twist and E-cadherin in hepatocellular carcinoma and their clinical significance. Methods The expressions of TRIM59,Twist and E-cadherin protein were tested by immunohistochemistry in 80 cases of hepatocellular carcinomas and the adjacent paracancerous tissues. Results The positive rate of TRIM59 in hepatocellular carcinoma was significantly higher than that in the adjacent paracancerous tissue(76.3%vs. 8.0%,P<0.05). Significant difference was also observed in the expres-sion rate of Twist between the hepatocellular carcinomas and the paracancerous tissue(66.3%vs. 6.0%,P<0.05). The positive rate of E-cadherin in hepatocellular carcinoma was significantly lower than that in the adjacent para-cancerous tissue(27.5%vs. 90.0%,P<0.05). The differences of the expression of TRIM59 in hepatocellular carci-noma of pathological grading,tumor differentiation,vascular invasion and clinical TNM stage were significant(P<0.05). The differences of the expression of Twist in hepatocellular carcinoma of pathological grading ,differentia-tion,vascular invasion and clinical TNM stage was also significant(P<0.05,respectively). The differences of the expression of E-cadherin in hepatocellular carcinoma of pathological grading,differentiation,vascular invasion and clinical TNM stage were also significant(P<0.05,respectively). Significantly positive correlation was also found between TRIM59 and Twist by using spearman correlation analysis(P<0.05). Negative correlations were observed between TRIM59 and E-cadherin(P < 0.05),and between Twist and E-cadherin(P < 0.05). Survival analysis showed that TRIM59 expression was an independent prognostic factor in hepatocellular carcinoma. Conclusion TRIM59,Twist and E-cadherin protein expression might be associated with the development,invasion,and metas-tasis of hepatocellular carcinoma. TRIM59 may become a new target gene for the treatment of human hepatocellular carcinoma.

[Objective] To explore the cytoprotecfion of hydrogen sulfide (H_2S) against cobalt chloride (CoCl_2)-induced apeptosis in PC12 cells and the underlying mechanisms. [Methods] CoCl_2 (a chemical hypoxia-mimetic agent) was used to establish the chemical hypoxia-induced PC12 cell injuries model. Sodium hydrosulfide (NaHS) was used as a H_2S donor. The viability of PC12 cells was measured by CCK-8 assay. The percentage of apeptotic cells was assessed by propidium iodide stain flow cytometry (FCM). The morphological change of apeptotic cells was tested by using the chromatin dye Hoechst 33258. The mitochondrial membrane potential (MMP) was analyzed by rhodamine 123 staining and photofluorography. The level of reactive oxygen species (ROS) in PC12 cells was measured by DCFH-DA staining and photofluorography. [Results] CoCl_2 induced a decrease in cell viability and an increase in percentage of apeptosis in PC12 cells along with dissipation of MMP as well as overproduction of ROS. When PC12 cells were treated with Naris 30 min before CoCl_2 treatment a decrease in viability of PC12 cells induced by 600 μmol/L CoCl_2 was concentration-dependently blocked by NaHs (100, 200, and 400 μmol/L). Pretreatment with NaHS at 200 and 400 μmol/L obviously reduced the apepetotic percentage of PC12 cells induced by 600 μmol/L CoCl_2 and inhibited the dissipation of MMP and overproduction of ROS. [Conclusion] H_2S protected PC12 cells against CoCl_2-induced apeptosis, which may be associated with the inhibition of H_2S on the dissipation of MMP and overproduction of ROS induced by CoCl_2.
