Cornus officinalis,a medicinal and edible plant known for its liver-nourishing properties,has shown promise in inhibiting the activation of hepatic stellate cells(HSCs),crucial indicators of hepatic fibrosis,especially when processed by high pressure wine steaming(HPWS).Herein,this study aims to investigate the regulatory effects of cornus officinalis,both in its raw and HPWS forms,on inflammation and apoptosis in liver fibrosis and their underlying *** vivo liver fibrosis models were established by subcutaneous injection of CCl4,while in vitro HSCs were exposed to transforming growth factor-b(TGF-b).These findings demonstrated that cornus officinalis with HPWS conspicuously ameliorated histopathological injury,reduced the release of proinflammatory factors,and decreased collagen deposition in CCl4-induced rats compared to its raw *** ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometer(UHPLC-QTOF-MS)combined with network analysis,we identified that the pharmacological effects of the changed components of cornus officinalis before and after HPWS,primarily centered on the adenosine phosphate(AMP)-activated protein kinase(AMPK)*** note,cornus officinalis activated AMPK and sirtuin 3(SIRT3),promoting the apoptosis of activated HSCs through the caspase cascade by regulating caspase3,caspase6 and *** interfering RNA(siRNA)experiments showed that cornus officinalis could regulate AMPK activity and its mediated-apoptosis through *** conclusion,cornus officinalis exhibited the ability to reduce inflammation and apoptosis,with the SIRT3-AMPK signaling pathway identified as a potential mechanism underlying the synergistic effect of cornus officinalis with HPWS on anti-liver fibrosis.

自从3D技术问世以来,VR、AR、MR等媒介技术不断涌现,改变了影视艺术的版图。裸眼VR介于3D和传统VR之间,它无须传统VR的交互设备,而是通过双目视差造成的深度错觉,使受众以裸眼探索虚拟现实的立体空间。双目视差的技术原理,继而引发了裸眼VR中“平面”和“纵深”之间的维度视差、看与被看之间的感觉视差、全知与未知之间的知觉视差。裸眼VR中的视差构型,呼应了中国传统卷轴画中“散点透视”与“焦点透视”这两种视觉构型,以及“人动画不动”与“画动人不动”这两种观看方式。本文将立足媒介考古学中的“视差史观”的方法,探索裸眼VR和卷轴画的跨时空观照,并以视差构型为例,阐明媒介理论从电影时代的“镜子”,计算机时代的“窗口”到裸眼VR时代的“门”的转向。裸眼VR与卷轴画的结合,能够推动中国传统美学在新媒体时代的发展,使得这种“前电影”时代的艺术形式,能够在“后电影”的技术环境中重新焕发生机。

本文从话本小说本事改写角度切入,以文学伦理学眼光观察明清话本小说语体转换现象。通过考察文白语体对应的道德伦理等级高低,揭示文人与庶民读者共塑了以话本小说为代表的明清白话小说的文学伦理。晚清小说革命促进了文人对小说语体的关注。他们利用白话语体的通俗性,引入小说载道观念,将低伦理等级的白话体扭转成高等级,并关涉现代性、进步等政治伦理。这一建构实挪用了西方文化语境,遮蔽了中国古代广义的话本体小说语体转化特有的集体性情绪表达层面的伦理意义。此外,本文结合中西文学文体发展史,辨析了明清白话小说及与之相关的俗文学语体混用与文体混用特征,阐释了其原因。
