原文和译文的关系常被看成是对等关系,而这种对等实际上是一种相对对等。认知语言学理论可以帮助我们从对等度、还原度和变通度三个维度来综合考察这种相对对等关系。本文详细分析了把事件、框架、认知域等看成翻译单位,继而从变通度来考察翻译对等关系的可行性,并且基于变式理论(Alternation Theory)将原文和译文看成是变式关系,是对同一事件语义的变通性认知识解,并从事件的词汇化、体识解和语义角色配置三个方面考察翻译过程中“变”与“不变”的绝对性和相对性,试图为从原文到译文的转化提供新的路径。

本文以王阳明《传习录》的英译本为对象考察译者在中国哲学典籍翻译中的译释层次。研究表明,译者的译释行为是由表及深的多层立体结构,从最表层到最深层,翻译的创造性经由五个层次逐渐加大,翻译也逐渐由工具上升到本体地位,最终与思想熔铸为一。译释层次分析在诸多方面具有理论优势,可以融入对译释学的系统性建构当中。

Parkinson’s disease (PD) is one of the most common neurodegenerative diseases. The loss of dopaminergic (DAergic) neurons in the substantia nigra and the decrease of dopamine (DA) levels accelerate the process of PD. L-Ergothioneine (EGT) is a natural antioxidant derived from microorganisms， especially in edible mushrooms. EGT can penetrate blood-brain barrier and its levels are significantly decreased in the plasma of PD patients. Therefore， we speculated that EGT could ameliorate PD， and determined its effect on PD development by using 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine (MPTP)-induced PD mouse models and neurotoxin 1-methyl-4-phenylpyridinium (MPP+)-induced cell models. Our results show that EGT alleviated MPTP-induced behavioral dysfunction in mice. Mechanistically， we innovatively revealed that EGT is a key regulator of DJ-1. EGT restored DA levels by activating the DJ-1-Nuclear receptor-related factor 1(Nurr1) axis. Furthermore， it reduced reactive oxygen species (ROS) levels by regulating the DJ-1-Nuclear factor erythroid 2-related factor 2 (Nrf2) pathway， which inhibited oxidative stress-induced DAergic neuronal apoptosis. Combined treatment with DJ-1-siRNA transfection revealed that blocking DJ-1 reversed EGT upregulated Nurr1 and Nrf2 expression in the nucleus， which significantly decreased the benefits of EGT. Taken together， our study suggests that EGT can ameliorate PD and be considered as a strategy for PD treatment.

苏轼(苏东坡)和王守仁(王阳明),这是两个在中华文化史上具有顶级影响力的名字。他们各自所处的时代相差400余年,不可同日而语;他们一个是北宋文学家、思想家、政治家,一个是明代哲学家、政治家、军事家;他们的生活道路、政治生涯、文化贡献、历史影响都很不相同。但苏轼和王守仁,有许多相似或相近之处,比如他们的社会背景、政治抱负、人生遭遇、思想倾向、文化情怀等等。比较苏轼和王守仁的相同与不同,对于认识、反思中国古代的政治生态和文化走向是有启示意义的。
