Lung cancer is a highly heterogeneous malignancy with a complex pathogenesis, involving a series of endogenous alterations such as genetic mutations, epigenetic modifications, and oxidative stress. Recent advancements in lung cancer research, especially at the genomic and molecular biology levels, have continuously provided new potential targets and perspectives for the diagnosis and treatment of lung cancer. Therefore, this article summarizes the recent progress in the study of endogenous factors related to the pathogenesis of lung cancer, aiming to enhance the understanding of intrinsic factors in lung cancer and to organize ideas for subsequent related research.

This paper reviewed the literature on medication rule of pulmonary nodules in recent years. It is found that contemporary doctors pay more attention to regulating Qi, clearing heat and detoxifying, eliminating phlegm, dissolving phlegm and dissipating masses. They use mild drugs, cold and warm treatments in parallel, combining the tastes of pungent, bitterness, and sweetness at the same time. The treatment focuses on the five viscera with emphasis on the lung meridian while also considering the spleen and stomach functions as well as soothing liver stagnation. This information aims to provide some reference for clinical treatment of pulmonary nodules.

以西安站改扩建项目为工程背景,完成足尺三孔斜交箱涵结构受力性能数值模拟研究,分析荷载与地裂缝协同作用下结构的受力过程与可能破坏形态,开展缩尺比例为1∶15的三孔斜交箱涵缩尺模型静载试验,与有限元结果进行对比分析,明确变形缝斜交和板墙开洞等复杂条件下箱涵结构的裂缝发展、位移变形和应力分布规律,验证了数值分析的可行性,并提出设计建议。结果表明:足尺数值模型与缩尺试验模型的应力路径和裂缝分布吻合较好;最不利工况下,箱涵顶板混凝土开裂部位较多,纵向挠度变形较小;斜交变形缝处,钝角较锐角处更易产生应力集中现象,各部位易出现应力集中的顺序依次为跨中、钝角、锐角和板墙隅角;采用平行于变形缝的斜向布筋方式可降低因钢筋截断而产生的应力集中,优化传力路径;建议在顶板洞口横向位置处增设暗梁,洞角布置斜向钢筋,降低洞口周围的局部集中应力。

Pasteurella multocida (PM) has been infecting a variety of hosts for a long time,causing sustained economic losses worldwide;however,there have been limited studies on its extensive adaptability (Aktories et al.2012).Analysis of strains data collected in our laboratory revealed that PM typically acquires foreign genes through transformation and conjugation,rather than transformation and *** and conjugative elements (ICEs)are a crucial mechanism that leads to abrupt changes in niche preferences and enhances environmental adaptability for bacteria,with their number far exceeding the number of plasmids and phages (Wozniak and Waldor 2010;Johnson and Grossman 2015;Botelho and Schulenburg 2021).Previous research has shown that the European bovine-sourced strain Pm36950 contains the experimentally transferable resistant ICEPmu1,which could integrate into the host chromosome or forming a circular intermediate (Michael et al.2012).Additionally,a few studies have suggested that PM strains isolated from European bovine and Asian swine might contain ICEs,but these claims lack experimental verification (Klima et al.2014;Moustafa et al.2015;Kadlec et al.2017;Peng et al.2017;Beker et al.2018;Schink et al.2022).Currently,there is no data available on ICE-carrying PM strains isolated from hosts outside of European cattle or Chinses *** letter presents a report on a novel ICE identified in the hypervirulent and multidrug-resistant PM HN141014 strain isolated from Chinese *** ICE was specifically analyzed for its resistance genes,transferable capacity and host diversity.

海上风电基础除承受复杂组合荷载作用外,也受波流冲刷作用.为探讨局部冲刷对砂土地基中V-H联合加载下单桩-摩擦盘复合基础承载特性的影响,基于自行设计的室内水槽试验装置,完成了一系列冲刷及模型载荷试验,获得了复合基础冲刷前后的荷载-位移曲线,经无量纲化处理与曲线拟合,得到复合基础承载包络线及其简化计算公式.计算结果表明:局部冲刷作用使复合基础的竖向及横向抗力明显降低,削弱程度分别约12.1%和26.9%.进一步分析表明:存在一个最优预加竖向荷载(V),其对复合基础的极限横向承载力起到最显著的增强效果;此外,局部冲刷作用导致V-H联合受荷单桩-摩擦盘复合基础的承载包络线明显向内收缩,所提出的简化计算公式可供工程应用参考.
