作者：赵晓兵薛大为赵玉祥 the command institute of the second artillery of pla University of Macao Luoyang Hydraulic Engineering Technology institute

In selecting rational types of underground structures resisting explosion,in order to improve stress states of the structural section and make full use of material strength of each part of the section,the research method of composite structures is presented. Adopting the analysis method of micro-section free body,equilibrium equations,constraint equations and deformation coordination equations are given. Making use of the concept of generalized work and directly introducing Lagrange multiplier specific in physical meaning,the validity of the constructed generalized functional is proved by using variation method. The rational rigidity matching relationship of composite structure section is presented through example calculations.

The impact of X-rays on the expressions of miR-130a/miR-25 and its potential role in the enhanced metastasis of A549 cell lines in vitro induced by X-rays

引用

Science China(Technological Sciences) 2013年第9期56卷 2243-2249页

作者： LV Jin WANG SiNian SONG XiuJun LI Xiao HE Rui YU HuiJie CHEN Shu WANG Lei JIANG QiSheng The second artillery General Hospital PLA

We aimed to investigate the impact of X-rays on miR-130a and miR-25 expressions of A549 cell lines and to understand the mechanism of miR-130a and miR-25 on the regulation of invasion and metastasis of A549 cell lines. Human adenocarcinoma cells of the line A549 were cultured and radiated by X-rays at the absorbed doses of 2 and 4, respectively by linear accelerator. Transwell invasion and migration assay were employed to exam the metastasis ability of A549 cells post X-rays irradiation. Both the miRNA and mRNA were extracted from A549 cells at different time points post radiation. The expressions of miR-130a and miR-25, as well as the expressions of VEGF and CCR-7 mRNAs, were detected in A549 cells with 2 and 4 Gy X-rays radiation, respectively by real time PCR. Results were statistically analyzed by SAS 8.2 software, which showed that the invasiveness of A549 cells post 2 and 4 Gy X-rays increased significantly compared with that of untreated A549 cells (the migration cell numbers are 20, 48 and 62 in Group 0, 2 and 4 Gy X-rays, respectively). Furthermore, the expressions of miR-130a and miR-25 also increased significantly at the time-points of 1, 2, 4, and 8 h post radiation, and began to decrease to the control level at 12 h post radiation. VEGF and CCR-7 mRNAs were detected to be up-regulated 18 h post radiation and remained at a high level till 72 h post radiation. The expression of VEGF mRNA has a close correlation with that of CCR-7 mRNA, and the expression of miR-130a also has a correlation with that of VEGF and CCR-7mRNAs. It is concluded that the metastasis of A549 cells in vitro could be promoted by X-rays, and miR-130a might play a role in the metastasis of A549 cells via regulating the expressions of VEGF and CCR-7 mRNAs.
