Dù Sījìng 杜思敬 (hào Zhúzhāi 竹齋, fl. early-Yuán Yányòu 延祐 period, ca. 1314–1320, 元), Yuán-period Shānxī physician and editor. Compiler of the Jǐshēng bácuì fāng 濟生拔粹方 (“Lifesaving Excerpts of the Best Formulas”), a 19-work medical anthology that transmits the JīnYuán four-master tradition (Liú Wánsù, Zhāng Yuánsù, Lǐ Dōngyuán, Wáng Hǎogǔ) and includes Dù’s own Zhēn jīng jiéyào 針經節要 (KR3ee019) as the acupuncture-doctrine pillar of the collection. The Bácuì was printed around 1315 in Shānxī and is the principal Yuán medical anthology after the Wèishēng bǎojiàn. No CBDB record could be matched with confidence; standard biographical reference is in Yán Shìyún’s Zhōngyī rénwù cídiǎn.
