一是编汇选名医成案。所选必择精当。如江氏类案入选颇多。亦不过十之三四。其余仅
选十之一二而已。此外见诸史传及说部杂书。或有新意。或立奇法者。间采一二条。俾广见
一所选皆有议论有发明之案。庸浅及怪诞不经者概删去。其有病同而治同。虽出两人。
止录一家。同之中必取前辈。或后辈之阐发胜于前辈。则取后舍前。亦无拘也。
一治病所凭在脉。故叙证而兼叙脉者始选之。若不载脉象。但侈治验。入选奚益。盖治
病之难。难于识病。识病之难。难于识脉也。然集中间收不载脉者。必辨证详明。或治法新
奇。或立论高超。不得以不载脉象而弃之。略备数条。以扩识见。
一前人案中。或涉鄙俚矜夸之语概削去。只存其脉证方论。以为后人认病之法。偶有文
繁及词晦者。僭为修饰之。不敢窜改其意。亦仅条达其辞以便观览而已。知我者谅不我罪。
一近日名医有年长于我者。有年少于我者。其治奇病着奇验必录之。今并附入。此皆生
平目击。并非得之传闻。若得之传闻者。姑为阙疑。不敢以误传误。
一成案以年代先后为编次。间有颠倒者。因病情相似。连类以便览。年代所不计也。至
于称谓前人。或名或字或别号及乡里。就人所易晓者称之。不拘一律。
一是编列为十卷。各分门类。以便查阅。至门类十三科实未能全。只就昔人有成案者选
之。每门多寡不拘。会心者闻一知十。可推展得其旨矣。
一各案引用之方。不能备录。间有附于案中及案后者。恐卷帙繁冗。录亦不详。嗣有古
今经验方按续出问世。
一诸案所载有妙义者。议论精详方药切当者。以及叙脉病因证候紧要关键处均加密点
若震自为按断之语。概不敢置密点。以俟高贤之教正。
一是编纂汇集选录名医的完整医案。所选案例必须精当恰当。例如《江氏类案》中入选的案例很多，但也仅占其中的十分之三到四。其余书籍中仅选取十分之一二而已。此外，从史书传记及笔记杂书中，如果有新意或创立奇特治法的，偶尔采录一两条，以拓宽读者的见识。
所选案例都必须有议论且有发明创见。平庸浅薄及怪诞不经的案例一概删去。如果病情相同而治疗方法也相同，即使出自两位医生之手，只记录其中一家。在相同的情况下，必须选取前辈医家的方案；或者后辈医家的阐发胜过前辈，则选取后辈而舍弃前辈，这也是不拘泥于固定规则的。
治病所凭借的依据在于脉象，所以叙述症状并兼述脉象的案例才予以选录。如果不记载脉象，只是夸大治疗效果，选入又有什么益处呢？大概治病之难，难于认识疾病；认识疾病之难，难于识别脉象。然而集中偶尔收录不载脉象的案例，一定是辨证分析详细明确，或者治疗方法新奇，或者立论高超，不能因为不记载脉象就抛弃它们。略微准备几条，以扩充见识。
前人的医案中，如果有涉及粗俗自夸的语言一概删去，只保留其脉象、症状、方剂和论述，作为后人辨认疾病的方法。偶尔遇到文字繁琐及词义晦涩的地方，僭越地加以修饰润色，不敢篡改原意，也只是理顺文辞以便阅读罢了。理解我的人想必不会怪罪我。
近日的名医中，有年龄长于我的，也有年龄短于我的，他们治疗奇病取得奇特疗效的，必定记录下来。现在一并附入书中。这些都是生平亲眼目睹的，并非道听途说。如果是道听途说的，暂时存疑，不敢以误传误。
成案的编排以年代先后为顺序。间或有颠倒的情况，是因为病情相似，连类编排以便浏览，年代就不计较了。至于对前人的称谓，或称名、或称字、或称别号及籍贯，就人们容易知晓的方式来称呼，不拘泥于统一格式。
本书编列为十卷，各分门类，以便查阅。至于十三科的分类实际上未能完全具备，只选取前人已有成案的类别。每门案例的多寡不拘泥于定数。用心的人闻一知十，可以推展领悟其宗旨。
各案例中引用的方剂，不能全部录出。间或有附在案例中及案例后的，恐怕卷帙繁多冗杂，录出也不详尽。以后会有《古今经验方按》陆续出版问世。
诸案例中记载有妙义的，议论精详、方药切当的，以及叙述脉象、病因、证候紧要关键之处，均加密点标记。如果是我俞震自己写的按断语，一概不敢放置密点，以等待高明贤达的指教校正。
One is the compilation and selection of complete medical cases by renowned physicians. The selected cases must be precise and appropriate. For instance, although many cases from *Jiang Shi Lei An* (Cases Classified by Jiang) were included, they account for only thirty to forty percent of that work. From other sources, merely ten to twenty percent are selected. Additionally, from historical biographies and miscellaneous notes, those presenting new insights or establishing unique treatment methods are occasionally excerpted to broaden readers' horizons.
All selected cases must contain discussion and original insights. Cases that are mediocre, superficial, or bizarre and unfounded are generally deleted. If the disease and treatment are identical, even if recorded by two different physicians, only one record is retained. In such instances of similarity, the case of a senior predecessor is preferred; however, if a junior physician's exposition surpasses that of the predecessor, the junior's case is chosen over the senior's, adhering to no rigid rule.
The basis for treating disease lies in the pulse diagnosis. Therefore, only cases that describe both symptoms and pulse characteristics are selected. If the pulse image is not recorded, but the therapeutic efficacy is exaggerated, what value does its inclusion hold? Generally, the difficulty in treating disease lies in recognizing the disease; the difficulty in recognizing the disease lies in identifying the pulse. However, cases without pulse records are occasionally included in this collection if the syndrome differentiation is detailed and clear, or if the treatment method is novel, or if the theoretical argument is profound. They should not be discarded solely due to the absence of pulse data. A few such cases are prepared to expand knowledge.
In previous physicians' cases, any language deemed vulgar or boastful is deleted. Only the pulse, symptoms, prescriptions, and discussions are preserved as methods for future generations to recognize diseases. Wherever the text is verbose or obscure, I have presumptuously polished it, without altering the original meaning, merely smoothing the phrasing for easier reading. Those who understand me will surely not blame me.
Among recent renowned physicians, some are older than I, and some younger. Their treatments of rare diseases yielding remarkable results are recorded and appended here. These are all observations made personally during my lifetime, not hearsay. Cases obtained through hearsay are temporarily omitted to avoid propagating errors.
The arrangement of complete cases follows chronological order. Occasionally, there may be deviations because similar conditions are grouped together for ease of browsing, disregarding strict chronology. Regarding titles for predecessors, whether using their given name, courtesy name, pseudonym, or hometown, the form most easily understood by people is used, without adhering to a single uniform standard.
This compilation consists of ten volumes, divided into categories for easy reference. Although the classification into thirteen departments is not fully comprehensive, it selects only those categories where predecessors have left established cases. The number of cases per category varies. Those with insight can infer much from a little and deduce the underlying principles.
Prescriptions cited in various cases cannot be fully recorded. Some are attached within or after the cases, but to avoid excessive volume and redundancy, they are not listed in detail. Subsequent works, such as *Gu Jin Jing Yan Fang An* (Commentary on Ancient and Modern Experienced Prescriptions), will be published sequentially.
For cases containing profound meanings, detailed discussions, and appropriate prescriptions, as well as critical points regarding pulse, etiology, and symptomatology, dense dots are marked. However, I dare not place dense dots on my own commentary (*An*), awaiting correction and guidance from superior scholars.
