Objective:To investigate the expression and relationship of differentiated embryo-chondrocyte expressed gene1(DEC1) and the signal tranducers and activator of transcription3 (STAT3) in gastric cancer tissues,and the significance of the two genes in gastric carcinogenesis. Methods:Immunohistochemistry method of SP was adopted to discover the expression of DEC1 and STAT3 in 59 gastric cancer tissues,19 normal tissues distant from tumor were regarded as control. Results:The positive expression rate of DEC1 in gastric cancer tissues was 71.2%(42/59),which was significantly higher than that in normal para-cancer tissues(26.3%)(P0.05). STAT3 expression was associated with TNM staging,invasion depth,lymph node involvement and tumor grade (P0.05). Conclusions:DEC1 expression was higher in gastric cancer tissues than that in normal para-cancer tissues distant from tumor,and was correlated with STAT3 in gastric cancer. DEC1 and STAT3 are both transcription factors,therefore the co-activation of DEC1 and STAT3 may play an important role in the carcinogenesis and development of gastric cancer.

Objective To evaluate the brain invasion in gliomas by diffusion tensor tractography(DTT).Methods Diffusion tensor imaging was preoperatively performed in 35 patients who histologically confirmed gliomas.13 of the 35 tumors were low-grade gliomas and 22 were high-grade gliomas. Then the spatial relationship between the lesions and white matter fiber tracts around tumor was analyzed. displacement, continuity and injured conditions of white matter fiber were observed. Results White matter fiber tract in all lesions could be observed clearly. Three patterns of white matter fibers involvement were identified:displaced,infiltrated and destructed. White matter fiber tracts around low-grade gliomas were primarily displaced ,but were mainly infiltrated and destructed around high-grade gliomas. Conclusion DTT was useful for showing white matter fiber tracts,observing the shape changes stereographically,and evaluating the relationship with gliomas in vivo.

Objective:To investigate the inhibitory effect of small interfering RNA-Yes-associated protein 1 (siRNA-YAP1) on epithelial-mesenchymal transition (EMT) in human lens epithelial cells (LECs) induced by transforming growth factor-β 2 (TGF-β 2). Methods:Human LECs line (HLEB-3) was cultured and divided into normal control group and TGF-β 2 induced group.The cells in the normal control group were treated with serum-free low-glucose medium for 24 hours, and the cells in the TGF-β 2 induced group were treated with additional 10 ng/ml TGF-β 2 for 24 hours.The cultured HLEB-3 cells were divided into siRNA empty vector group, siRNA-YAP1 transfection group, siRNA empty vector+ TGF-β 2 group and siRNA-YAP1+ TGF-β 2 group, and the cells were transfected with plasmid including siRNA empty vector or siRNA-YAP1 sequence according to grouping.The relative expression levels of YAP1 mRNA and protein in various groups were detected and compared by quantitative real-time polymerase chain reaction (PCR), immunofluorescence and Western blot assay, respectively.The relative expression levels of EMT marker proteins (E-cadherin and Vimentin proteins) in various groups were detected by immunofluorescence and Western blot assay. Results:Compared with the normal control group, the expression level of E-cadherin protein was decreased (1.180±0.118 vs.0.830±0.104) and the Vimentin protein was increased (0.797±0.110 vs.1.240±0.110) in the TGF-β 2 induced group, with significant differences between the two groups ( t=3.857, P=0.018; t=-4.933, P=0.008).The relative expression levels of YAP1 mRNA and protein in the TGF-β 2 induced group were significantly increased in comparison with the normal control group (2.200±0.193 vs.1.136±0.123; 1.203±0.121 vs.0.967±0.025), with significant differences between the two groups ( t=-9.288, P<0.01; t=-3.329, P=0.029).Compared with the siRNA empty vector group, the expression levels of YAP1 mRNA and protein in the siRNA-YAP1 transfection group were significantly reduced (both at P<0.01).Compared with the siRNA empty vector+ TGF-β 2 group, the relative expression level of E-cadherin protein was significantly enhanced and the expression level of Vimentin protein was significantly reduced in the siRNA-YAP1+ TGF-β 2 group (both at P<0.01). Conclusions:YAP1 participates in the TGF-β 2 induced EMT in human LECs, and siRNA-YAP1 can suppress the EMT process.
