Anisotropy is a significant and prevalent characteristic of materials, conferring orientation-dependent properties, meaning that the creation of original symmetry enables key functionality that is not found in nature. Even with the advancements in atomic machining, synthesis of separated symmetry in different directions within a single structure remains an extraordinary challenge. Here, we successfully fabricate NiS ultrafine nanorods with separated symmetry along two directions. The atomic structure of the nanorod exhibits rotational symmetry in the radial direction, while its axial direction is characterized by divergent translational symmetry, surpassing the conventional crystalline structures known to date. It does not fit the traditional description of the space group and the point group in three dimensions, so we define it as a new structure in which translational symmetry and rotational symmetry are separated. Further corroborating the atomic symmetric separation in the electronic structure, we observed the combination of stripe and vortex magnetic domains in a single nanorod with different directions, in accordance with the atomic *** manipulation of nanostructure at the atomic level introduces a novel approach to regulate new properties finely, leading to the proposal of new nanotechnology mechanisms.

Potential preservative mechanisms of cardiac rehabilitation pathways on endothelial function in coronary heart disease

Science China Life Sciences 2024年

Cardiac rehabilitation, a comprehensive exercise-based lifestyle and medical management, is effective in decreasing morbidity and improving life quality in patients with coronary heart disease. Endothelial function, an irreplaceable indicator in coronary heart disease progression, is measured by various methods in traditional cardiac rehabilitation pathways, including medicinal treatment, aerobic training, and smoking cessation. Nevertheless, studies on the effect of some emerging cardiac rehabilitation programs on endothelial function are limited. This article briefly reviewed the endothelium-beneficial effects of different cardiac rehabilitation pathways, including exercise training, lifestyle modification and psychological intervention in patients with coronary heart disease, and related experimental models, and summarized both uncovered and potential cellular and molecular mechanisms of the beneficial roles of various cardiac rehabilitation pathways on endothelial function. In exercise training and some lifestyle interventions, the enhanced bioavailability of nitric oxide, increased circulating endothelial progenitor cells(EPCs), and decreased oxidative stress are major contributors to preventing endothelial dysfunction in coronary heart disease. Moreover, the preservation of endothelial-dependent hyperpolarizing factors and inflammatory suppression play roles. On the one hand, to develop more endothelium-protective rehabilitation methods in coronary heart disease, adequately designed and sized randomized multicenter clinical trials should be advanced using standardized cardiac rehabilitation programs and existing assessment methods. On the other hand, additional studies using suitable experimental models are warranted to elucidate the relationship between some new interventions and endothelial protection in both macro-and microvasculature.

邦有道,亦可隐:东汉初年的隐逸风气与正统重建

东汉初年,中国历史上首次出现大批士人隐逸,其背后蕴含皇权消长、政局波动、天命承接、个人崛起、风俗迁移等种种意涵。经历了两汉之际诸政权没有定数的竞夺,西汉士人带着谁是“猎者”的困惑,开始处理其与东汉王朝的关系。隐逸成为他们选择的一种方式。隐逸者多为西汉遗臣耆老,他们对年轻的刘秀集团并不信任,对后者建立新汉朝的合法性、对两汉承续关系多有怀疑,隐逸是他们宣示抵而不抗的一种姿态。选择出仕者与光武帝在政见上多有不合,又因谏诤而遭致排抑,唯有隐退方能保存尊严。面对众多士人的“不臣”,光武恩威并施,采取“圣主不宾”的策略,以容忍隐者、鼓励守节彰显自己“明王圣主”的品质。这种政策助长了隐逸的风气,推动了个体自立潮流的泛滥,形成东汉初年一种“邦有道,亦可隐”的新观念。隐逸的正当化,既缓解了遗臣士人与光武集团的紧张关系,又使隐逸转化为东汉重建正统的思想资源。“隐”由此获得了独立存在的意义。

一前不久看一篇评论家综论,提及“70后”的创作,认为这一代作家执念于细节的营造,同时也因过于拘泥细节,而未获取足够开阔的视野,也未抵达更为幽深的人性观照。我读罢这一段,脑子迅速扫描我熟悉的一些“70后”作家及创作。作为一个群体,我们起初似乎都排斥“70后”这样笼统粗率的命名,但随着写作的推进,这一代人整体步入中年,“70后”的指称也一直未有更好的替代,慢慢我们开始接受、认领。毕竟我们不能否认,我们就是一代人。起初感觉这样的命名什么也没说,慢慢觉得它把什么都说了,甚至具有某种预言性质:你们只是整体清晰而个体贫弱的一代人。所以,“70后”老早又被冠名为“夹缝的一代”。相对于晚一点的“80后”,“70后”的个人面孔相对模糊,而“80后”个人仿佛自带一种横空出世的禀赋,比如早一点的韩寒,稍晚的双雪涛,近几年的班宇。

东汉前期新设兰台,皇帝征召兰台之官。兰台文雄会聚,成为一个职能清晰的官方文艺机构。兰台文人用史、赋、颂、传记述东汉获得天命、功致太平的历程,由此形成一系列“文”的实践活动。班固等在兰台撰著《世祖本纪》,编织光武帝事迹,彰显其创业之功,确立开国史叙述;兰台文人撰著多篇“都赋”,以迁都洛阳隐喻东汉受命,批评西汉之承秦,凸显“汉历中绝”,建构“建武革命”的观念;文人创作《哀牢传》《神雀颂》等,染“万夷宾服”,暗喻东汉的统治区域达到前所未有之广阔。文人作“汉颂”,比拟《周颂》,传达古今同况、功成德洽之义。这一系列文章实践是明、章时代一场重要的政治文化工程,是东汉王朝重建合法性的自我表达。
