基于多学科诊疗模式背景和患者日益增长的高质量生活意愿,近年来低位直肠癌保肛策略发生改变。随着新辅助治疗模式的优化、手术术式的精化以及术后保肛理念的深入人心,低位直肠癌保肛策略逐渐从传统的单纯手术转变为综合治疗,保肛手术也更倾向于精准、极限保肛。综合治疗旨在为患者保留良好的肛门功能,减轻手术损伤。但低位直肠癌保肛综合治疗仍处于新兴发展阶段,对保肛的策略规划尚未达成共识。因此,总结各类低位直肠癌术前、术中、术后的治疗策略,对于低位直肠癌患者保肛方案的选择具有重要意义。本文着重探讨新辅助治疗模式的优化、“观察等待”方案、保肛技术的发展以及术后保肛策略等,旨在对低位直肠癌保肛策略规划的现状进行综述。

正断层阶区有软连接(soft-link)和硬连接(hard-link)2种端元连接模式。判定正断层阶区现今的连接模式不但有助于理解正断层的生长演化过程,也能指示未来正断层上发生的地震是否会在阶区内形成地表破裂,这对于评价阶区内工程场地的地震安全性具有重要意义。判定正断层阶区内是否存在活动的连接断层是区别正断层阶区现今连接模式的直接方法。然而,在多数情况下,由于正断层阶区内的变形量相对小,加上人类活动对阶区内地貌的改造,导致在本以硬连接模式生长的正断层阶区内也很难直接看到断层陡坎,这为判定正断层阶区内是否存在活动的连接断层带来了困难。山西裂谷系是东亚大陆显著的活动裂谷带,也是中国重要的强震带。口泉断裂位于山西裂谷系北部,是大同盆地的西缘边界断裂。口泉断裂在禅房村附近发育一个正断层阶区,文中称之为禅房阶区。文中以口泉断裂禅房阶区为例,通过构造地貌野外调查、地貌数据分析和地质雷达探测研究禅房阶区的连接模式。结果显示,口泉断裂禅房阶区内部存在活动的连接断层,说明禅房阶区的连接方式为硬连接模式。文中研究基于构造地貌野外调查、地貌数据分析和地质雷达探测的综合方法,可有效定位弱活动断层的空间展布,降低单一方法的不确定性。

Adhesive Contact of Elastic Solids with Self-Affine Fractal Rough Surfaces

Acta Mechanica Solida Sinica 2024年第2期37卷 265-270页

作者： Xuan-Ming Liang Shi-Wen Chen Si-He Wang Zhen-Yuan Gong Jun feng Gang-feng Wang Department of Engineering Mechanics SVL and MMMLXi’an Jiaotong UniversityXi’an710049China OPPO Mobile Telecommunications Corporation Ltd. Dongguan523860China

The elastic adhesive contact of self-affine fractal rough surfaces against a rigid flat is simulated using the finite element method. An array of nonlinear springs, of which the force-separation law obeys the Lennard–Jones potential, is introduced to account for the interfacial adhesion. For fractal rough surfaces, the interfacial interaction is generally attractive for large mean gaps, but turns repulsive as the gap continuously shrinks. The interfacial interactions at the turning point corresponding to the spontaneous contact are shown for various surfaces. For relatively smooth surfaces, the probability density distributions of repulsion and attraction are nearly symmetric. However, for rougher surfaces, the simulation results suggest a uniform distribution for attraction but a monotonously decreasing distribution with a long tail for repulsion. The pull-off force rises with increasing ratio of the work of adhesion to the equilibrium distance, whereas decreases for solids with a higher elastic modulus and a larger surface roughness. The current study will be helpful for understanding the adhesion of various types of rough solids.

Amyotrophic lateral sclerosis(ALS)is a fatal neurodegenerative disease characterized by progressive degeneration of motor neurons,and it demonstrates high clinical heterogeneity and complex genetic architecture.A variation within TRMT2B(c.1356G>T;p.K452N)was identified to be associated with ALS in a family comprising two patients with juvenile ALS(JALS).Two missense variations and one splicing variation were identified in 10 patients with ALS in a cohort with 910 patients with ALS,and three more variants were identified in a public ALS database including 3317 patients with ALS.A decreased number of mitochondria,swollen mitochondria,lower expression of ND1,decreased mitochondrial complex I activities,lower mitochondrial aerobic respiration,and a high level of ROS were observed functionally in patient-originated lymphoblastoid cell lines and TRMT2B interfering HEK293 ***,TRMT2B variations overexpression cells also displayed decreased *** conclusion,a novel JALS-associated gene called TRMT2B was identified,thus broadening the clinical and genetic spectrum of ALS.
