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。

With increas.ng life expectancy， neurodegenerative dis.as.s.have become one of the leading caus.s.of ill-health in the elderly. Preventive s.rategies.include following healthy diets. s.ch as.the Mediterranean diet， which is.particularly rich in polyphenols. bioactive compounds.with neuroprotective properties. The aim of this.s.udy was.to as.es. the as.ociation of microbial phenolic metabolites.(MPM) with cognition. This.cros.-s.ctional analys.s.was.performed with 200 participants.of the PREDIMED trial (Barcelona-Clinic recruitment center). A novel method bas.d on liquid chromatography coupled to mas. s.ectrometry was.us.d to identify urinary MPM (protocatechuic acid， enterodiol glucuronide， enterolactone glucuronide， urolithin B glucuronide， and vanillic acid glucuronide)， and cognitive function was.evaluated with neurops.chological tes.s. Multivariable-adjus.ed ordinary leas. s.uares.regres.ion was.us.d to as.es. the as.ociations.between cognitive function and MPM， and a s.ore was.calculated as.the weighted s.m of MPM. A higher MPM s.ore was.as.ociated with better frontal lobe function. Among individual metabolites. vanillic acid glucuronide was.correlated with frontal cognitive performance. Participants.with higher concentrations.of vanillic acid glucuronide and urolithin B glucuronide obtained better s.ores.in the Color Trail Tes. part 2. A higher s.ore for urinary multi-MPM was.as.ociated with better frontal cognitive performance in an older Mediterranean population.
