【目的】探究在客土喷播基材中添加不同长度纤维材料对土体抗剪强度和抗压强度的影响。【方法】采用控制变量的试验方法,以不同长度(1、2、3、4、5 cm)的椰丝纤维和砂土为试验材料,按0.4%(w/w)的质量比混合后进行了室内三轴试验和无侧限抗压试验。【结果】(1)各长度纤维加筋土在各围压下的主应力差峰值强度和抗压强度峰值都大于无纤维加筋的素土;(2)随着纤维长度的增加,主应力差峰值强度、内聚力、内摩擦角和加筋效果系数都呈现出先增加后减少的趋势,且在长度为3~4 cm时,强度达到峰值;(3)随着纤维长度的增加,抗压强度峰值,主应力差强度峰值及破坏后的残余强度都得到明显提升,应力-应变曲线逐渐由应变软化型过渡为应变硬化型。【结论】掺量为0.4%、长度为3~4 cm的椰丝纤维可以有效提升土体的抗剪强度和抗压强度。

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2014年第10期15卷 864-869页

作者： jin-ming CHEN jin lv Kai MA jing YAN Department of Emergency Medicine the Second Affiliated Hospital School of Medicine Zhejiang University Department of Emergency Medicine Zhejiang Hospital Department of Thoracic Surgery the Affiliated Hospital School of Medicine Qingdao University

The occurrence, bleeding, and treatment of internal mammary artery（IMA） injury after blunt chest trauma have not been well described in the literature. We reviewed articles published from July 1977 to February 2014 describing IMA injury after blunt chest trauma in 49 patients. There was a predominant incidence in males and on the left side. Blunt trauma to the IMA can cause anterior mediastinal hematoma, hemothorax, pseudoaneurysm, arteriovenous fistula, and extra-pleural hematoma. Of the 49 patients studied, 20 underwent embolization, 22 underwent surgical operation, 4 were managed by clinical observation, and 3 had undescribed treatment. Different parts and extents of IMA injury, adjacent vein injury, as well as the integrity of the pleura determined differences in bleeding modality. Prompt diagnosis, complete hemostasis, aggressive resuscitation, and multidisciplinary teams are recommended for patients with IMA injury.

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.

An approach utilizing N-heterocyclic carbene for nitrile formation and desymmetrization reaction is developed. The process involves kinetic resolution, with the axially chiral aryl monoaldehydes obtained in moderate yields with excellent optical purities. These axially chiral aryl monoaldehydes can be conveniently transformed into functionalized molecules, showing great potential as catalysts in organic chemistry.
