Shěn Zhīwèn 沈之問 (zì Liángzhāi 良齋, fl. Jiājìng, 1522–1566, 明), Míng-period specialist on leprosy and chronic skin-and-nerve disorders. Author of KR3ek035 Jiěwéi yuánsǒu 解圍元藪 (4 juǎn), one of the earliest dedicated Chinese monographs on what later medicine calls máfēng 麻風 (leprosy) and the broader fēng / lài disease cluster. The work surveys the textual tradition from the Língshū and Sùwèn through Cháo Yuánfāng’s 巢元方 Zhū bìng yuánhòu lùn 諸病源候論, and systematises 36 fēng across the six visceral systems, with strong attention to contagion and intra-family transmission via both fùmǔ jīngxuè 父母精血 (inherited essence-blood) and qìhuì gǔzhù 氣穢蠱疰 (miasmic contact). Together with 薛己 Xuē Jǐ’s contemporaneous KR3ek038 Lìyáng jīyào (1554), Shěn’s work is the principal Míng documentary witness for Angela Leung’s reconstruction of the Míng-period Chinese rewriting of leprosy as a transmissible disease (Leprosy in China, 2009). Lifedates not documented; not in CBDB.
