Hepatic ischemia-reperfusion injury（HIRI） is characterized by mitochondrial dysfunction and oxidative stress. Monitoring mitochondrial hydrogen peroxide（mtH2O2） levels in real-time through super-resolution imaging is crucial for elucidating its distribution in live cells and its mechanism of action during HIRI. However, low-background fluorogenic probes have been overlooked in the context of super-resolution imaging. In this study, we developed a low-background fluorogenic probe（MitoWG） with the potential for super-resolution morphology-correlated mitochondrial identification to track the fluctuates of mtH2O2in HIRI. Activation of the desirable fluorescence properties of the probe by mtH2O2was confirmed using structural illumination microscopy（SIM）, enabling high-quality mitochondrial imaging with exceptional specificity and *** in mtH2O2levels were successfully observed in both cellular and rat models of HIRI. Furthermore, we associated the decline in mitochondrial redox homeostasis with accelerated mtH2O2production during HIRI, which triggered mitophagy deficiency and led to cell death. In conclusion, Mito-WG possesses excellent photophysical and low-background properties for SIM imaging, making it a promising tool for mtH2O2tracking in HIRI research and clinical diagnosis.

汉语兼具“文”与“言”的双重属性,与以“言”为主的印欧语相区别。语法与逻辑的同根同源使印欧语在理论表述中陷入了概念与经验的争执,而汉语贯通形而上与形而下的特质使汉语表述本身即构成一种方法。作为“道”之文的载体,中国早期记录及其文法结构提供了关键信息,甲骨卜辞的体例制式为“易”类文献的结构提供了可追溯的原型,也为探索“论出于易”对汉语诗学功能的塑造提供了重要线索。其中,干支配伍的宇宙纪日为“以时系事”的话语表述提供了超线性时空结构;“正反对贞”以对言的形式表现语义的动态平衡与赋形必变的道理;“主题+阐释”的体例结构以逐层累积的文本层次为断言的疑难提供了积极的方案。汉语文法能够在表述判断的同时保持对“变”的关切,这为建构既能规范描述艺术经验又能直面人类自身处境的理论话语提供了时代价值。

六经是中国传统文化的核心经典,六经皆治欲:《尚书》与《春秋》治欲体现在为政之正;《诗经》治欲体现在思无邪与引导欲望的合理释放与适度满足;《周易》治欲是针对深隐欲望的几占以及损益配合等;《礼经》之礼与《乐经》之乐联动,具有进与反之美。六经显示出中国古典学治欲资源的丰富,并且它们之间相互渗透,统一在各经皆礼、以礼治欲,表现为约束与温和释放欲望的对立统一。纵向展开,中国传统文化在前轴心时代、轴心时代、近世社会的治欲特点可表述为六经皆治欲、四书皆治欲、理学皆治欲,三者的发展既有连续性,亦各有时代特色。横向对比,中国古典学的六经治欲与禁欲主义、神秘主义对立,属于世俗化、人文化的治欲方案。伴随着全球世俗时代的到来,六经治欲的特色与优势愈加凸显。
