Objective:To study the mechanism of effect of miR-21 via Wnt/β-catenin signaling pathway in human A549 lung cancer cells and Lewis lung carcinoma in mice. Methods:The effect of miR-21 on A549 cells were detected by MTT method. MiR-21 expression levels were overexpressed or inhibited in A549 cells by transfecting with miR-21 mimics or inhibitors. Correlation among key molecules (Wnt1,β-catenin, CyclinD1 and miR-21) of mRNA and protein levels in Wnt/β-catenin signaling pathway were studied by Real-time PCR and Western blot hybridization assay. Invasive ability of A549 cells was determined via Transwell chamber cell invasion assay;the role of miR-21 in A549 cells was explored via the Wnt/β-catenin signaling pathway. A Lewis lung carcinoma animal model was established to detect miR-21 expressions in tumor animals and controlled animal tissues, and verify expression changes of the above moleculesin the Wnt/ β-catenin signaling pathway was determined in the animal level. Results:MTT assay results showed that miR-21 overexpression could markedly enhance cell absorbance value;that is, miR-21 could increase the ability proliferation of A549 cells.β-catenin and CyclinD1 expression levels were significantly higher in miR-21 mimic transfected cells (P<0.05), and Wnt1 gene had no significant change. Wnt1,β-catenin and CyclinD1 gene expression showed no significant change when miR-21 expression was suppressed, compared with controls. After cells were transfected with miR-21 mimics, cell invasion assay revealed that the perforated cells was significantly higher than the perforated cells in the control group (P<0.01). Lewis lung assay revealed that miR-21 expression levels in the Lewis lung carcinoma were significantly higher;and at the same time, Wnt1,β-catenin and CyclinD1 gene expression levels were significantly increased, compared to controls. Conclusions: In A549 human lung cancer cells and Lewis lung carcinoma in mice, key moleculesβ-catenin and CyclinD1of miR-21 expressions and the Wnt/β-catenin signaling pathway are positively correlated.

This thesis found the female homicide cases present its own characteristics because of differences in psychological, physiology characteristics, character between males and females through the statistical analysis of age distribution, the relationship between criminal suspects and victims, the classification of crime scenes, injury tools and the mortal wound positions of 116 female homicide cases in Lianyungang between 1993 to 2014. Mostly, the relationship between criminal suspects and victims is family, especially couple or valentine; the crime scenes are frequently indoor, especially bedrooms. They always choose production and life tools when victims are in deep sleep or drunk time to make the victims asphyxia, posioning or drowning. The injuries focus on vitals and usually hit many times lead to mortal wound, agonal trauma and postmortem injury.
