许叔微伤寒著述成书考论

Textual research on the time of completion of XU Shuwei＇ books on exo - pathogenic cold diseases

许叔微伤寒著述今存《伤寒百证歌》《伤寒发微论》《伤寒九十论》3种。这3部书成书后流传不广，虽然有元、明刊本，但一直沉寂不显，直到清代才渐有医家征引。通过比对文本发现，《伤寒百证歌》之名见于许叔微的其他医著中，而《伤寒发微论》与《伤寒九十论》有部分内容则相互重复，甚至观点相异。由史料考察可知，许叔微现存的3部医书在北宋末年已经开始撰写。南宋初年渡江之后，许叔微整理残稿，在此基础上继续写作。其中《伤寒百证歌》最先成书，《伤寒发微论》次之，《伤寒九十论》成书最晚。

Shang han bai zheng ge （Poets of Syndromes of Exo-pathogenic Cold Disease）, Shang han fa wei lun （Discourse on Elucidation of Exo-pathogenic Cold Disease ）, Shang han flu shi lun （90 Discourses on Exo-pathogenic Cold Disease） were the three extant books on exo-pathogenic cold disease written by Xu Shuwei among his other works of its kind. Although there were carved editions of the Yuan and Ming Dynasties, these books were gradually paid attention for citations by other physicians till the Qing Dynasty.
