简述宋人对《千金要方》散剂的改动

Changes of powder prescriptions in Qian jin yao fang （ Essential Prescriptions Worth A Thousand Gold） made by Song people

《千金要方》两种重要传本《备急千金要方》、《新雕孙真人千金方》在内容上多有不同，其中在方剂文献方面的差异特别值得重视。宋人对《千金要方》原书的散剂相关内容进行了诸多改动，包括论述散剂的章节与内容、药味计量单位、药味重量、散剂制法等，其所有的改动均无任何标示，书前的“凡例”亦无任何说明。从内容来看，由于增补了诸多散剂相关医学资料，宋校本较之新雕本显然更为丰富，书籍的章节编排更为明确合理。作为中医临床百科全书，宋校本更便于阅读与使用。但从传统的文献整理的角度来看，径改原书确为学者之大忌。

As the contents in the two circulated versions of Qianfin yaofang （Essential Prescriptions Worth A Thousand Gold） ,i. e Bei fi qian fin yao fang （Essential Prescriptions Worth a Thousand Gold for Emergencies ） and Xin diao sun zhen ren qian fin fang （ Newly Printed Sun＇ s Prescriptions Worth A Thousand Gold） are different greatly, especially on the literature of prescriptions. Song people made a lot of changes on the contents of powder prescriptions, including the related chapters and its contents, computation unit of materia medica, weights, and processing methods etc. without any remarks, nor notes in its preface. The contents in the Song version were more enriched than the newly carved version with the reasonable arrangement of its texts. As a clinical encyclopedia of traditional Chinese medicine, the Song version is more convenient for reading and using. However, it is a great taboo for the scholars to tamper an ancient work at will from bibliographic viewpoints.
