序一
曹孟德曾经吟过这样的名句:“老骥伏枥,志在千里,烈士暮年,壮心不已。”作为一个在杏林苑中耕耘了数十个春秋的人,总结自己的临床经验和学术理论,为人类的健康与中医学术的发展,作出应有的贡献,这既是我的心愿,也是我的责任。但是,由于诊务常常忙得不可开交,加上年届耄耋,精力渐衰,我的书稿写了多年还未完成。
现在,孟城却后来居上了。他是我的学生,是我众多学生中出类拔萃的一个。他经过几十年兢兢业业、孜孜不倦的追求和努力,已获得了可喜的成果。《三十年临证探研录》不仅是他学术经验的集中体现,也是他对祖国和人民的一次成绩汇报。孟城是个精勤不怠、学而不厌的人,他极其尊敬自己的各位师长,对师长们一言半语的教诲,都记忆在心。因此,书中内容多有他与诸师传承关系的自然流露。
孟城的这本著作,据我个人的体会,有以下五个特点:第一、态度严谨,资料可靠。孟城无论治学还是处世,始终是严谨的,坚持实事求是,力戒虚伪浮泛。本书所涉及的病例,写作前他都经过直接或简接的随访。疗效确切,方才引作资料。而且全书文字朴实,不事渲染,也可从另一角度反映出他的严谨精神。
第二、辨证精确,细致人微。如第13篇“外感风热误药致变”中,沈氏发热神昧,辨为风热挟痰,劫伤津液,用加减萎蕤汤化裁得愈。又如惊恐重症治以补养,脑挫伤治以镇肝熄风法。小儿肺炎治以清肠泄热,心房纤颤治以养心宁神等诸多病例的辨证治疗,都较为精细确切,所以能收到极高的疗效。
第三、处方简洁,用药轻灵。书中不少效果独特的验方用药极为简洁,甚至往往以单味药取效,这是一个极为重要的特点。约少而精,与疾病针锋相对、单刀直入,常可出奇制胜,而且没有复方中药物之间相互牵制的弊病。如用单味代赭石治脑震荡,酒煎红藤治急慢性阑尾炎,霜桑叶煎洗结膜炎等具有简洁高效、药到病除的特点。同时,在使用复方时,用药的剂量每常较轻,但从病例观察可知,同样收到了应有的治疗效果。这是一个很有价值的应用尝试,既可减少药物对病人肌体的影响,又可节省药材,具有进一步实验研究的价值。
第四、深入钻研,创制新方。书中用以康复中风偏瘫的“偏枯健全汤”;纠正面神经瘫痪的“圣愈正容汤”;治疗精神分裂的“镇肝涤痰汤”及蠲除老慢支的“百合畅肺饮”等四首特效处方,均系孟城经过多年lI缶床实验研究后制作的新方,用以治疗适应病证,常能收到预期的效果。这是他对祖国医学的又一重要奉献。
同时,书中所介绍的其他方药与方法,也具有简洁、高效、堪经重复的特点,因而值得推广应用。
第五、通盘考虑,实践整体均衡治疗。“整体均衡疗法”是孟城长期以来始终坚持,并不断为之探索研究的治疗法则,用以治疗历久不愈、症情错综复杂的疑难杂病具有特殊效用。
书中没有明确提出这一观点,是因为目前尚在孕育之中,还未成熟。但书中许多复杂病例的辨治过程,无不贯穿和体现了这一点。“整体均衡治疗”是孟城学术观点中的一种创见,虽
然先哲著作中也有类似的学术思想存在,然多属散在和初步的,没有升华、结晶。孟城本着继承和发展的精神,正在深入研究。而这一思路与方法,却已在本书的字里行间跃然纸上,
读者如能别具慧眼,自有会心之处。
孟城在事业上具有勇往直前的精神。经过三十年不寻常的实践和研究,他终于获得了今日的成就。“戒骄戒躁,再接再厉,争取更大的业绩!”这是我对孟城的一点勉励与期望。

序二
我告别祖国和上海,到美国求学而后留美行医,已经整整十个年头了。在这期间,我常常忆念上海的亲朋好友。孟城是我早年在沪学医时的同窗好友。在学术上,无论是理论还是实践,他始终是一个孜孜不倦努力进取的人。现在见到了他的第一部著作《三十年临证探研录》,我非常高兴,因而激动地为它作序。
在祖国医学绚烂多彩的百花园中,到处都有奇花异草可寻,如果你善于采集的话,是一定会有收获的。《三十年临证探研录》是孟城数十年来部分临证心得的汇集,也是一次杏苑采宝的小小展示。“满园春色关不住.一枝红杏出墙来”。它不仅是一部冶理法方药于一炉的好书,而且毫无保留地把自己的经验和盘托出,奉献给读者和医界,这种可贵的精神使我最为感动。就书中的内容来看,侧重于医疗技术,但是,现代医学对于健康的含义,正如本书所说的,包括了生理与心理两个方面,特别是心理的反馈与影响,日益显示出重要的作用。
“无形主宰意念力”是作者运用祖国传统的医学理论,研究医学领域内心理反馈现象的一次大胆尝试,是很有意义的。心理的自我锻炼与完善,是人们获得健康心理的最佳途径与方法,而心理健康又是生理健康的有效前提和保证。只有通过不断的以健康心理克服和取代不健康心理的长期训练,才能达到高尚的心理境界,从而享受生理健康与长寿的乐果。祖国医学已经走出国门,进入世界医学的金色殿堂。它是一颗璀灿的明珠,必然会对人类的健康作出重大的贡献。值此机会,愿孟城的这一部著作,光芒焕发,青春永驻。

述作类
临证须辨疑似
治病首重识证,此为历代医家一致共识,如《临证指南》曰:“医道在乎识证、立法、用方,此为三大关键”,“然三者之中,识证尤为紧要”。而识征之关键在于辨证,何谓辨证?所谓证,即是疾病发生发展过程中反映疾病某阶段本质之一种概念。辨证是在全面搜集四诊素材基础上,运用四诊、八纲、脏腑、病因、病机等基础理论,进行分析、推理,综合判断,从而得出相对合理之证候诊断。然由于病者之体质、宿疾、病情轻重、精神情志、服药机变、失治误治以及生活之环境、气候、地域之类因素影响,常可导致证情错综复杂,出现近似、类似或假似等疑似之证,混淆视听,致使医者一时难以确诊,其至真假难辨,稍一疏漏,即堕五里雾中。如阴盛之极,格阳于外,反见面红目赤、唇破舌裂、扬手掷足、语言错妄,一派火热之象,初看似属阳汪,实则内真寒而外现假热;阳热之极,格阴而见四肢发厥,热深厥亦深,僵卧如尸、不饮不食、口鼻无气、手足逆冷,一派阴寒之象,初看似属阴证,实则内真热而外现假寒。又如癌症患者,证实脉亦实,常见肢体懈惰、眩晕眼花、纳呆神疲,似乎虚证;而劳伤中气之人,反见脘腹胀满,食则不舒、气机壅滞、大便欠利,却似实证。以上仅略举数例,而临证之际,疑似之证未可胜道。故李士材喟然感叹曰:“诸凡疑似之症,不可更仆数。”而林珮琴于《类证治裁》自序中亦曰:“司命之难也在识证,识证之难也在辨证,”“且于一症,错综疑似。”因而抉别真伪、辨析疑似又为辨证不可缺之重大环节。
因为用以辨证之主要依据是四诊所得各种素材,所以辨析疑似也须从深入细致地分析、比较此类素材入手。以笔者之粗浅体会,其中似可侧重于主症、脉象及舌象之辨析。
一辨主症特点,推求同中之异。辨证方法是应用中医之基础理论,对望闻问切四诊素材加以分析筛选、分类排比,然后归纳综合,从认定主症开始。能否正确选择与识别主症,即是能否正确辨证之重要标志。如果主症选择失误,常可导致错误之证候诊断。
为防止主症辨识时可能出现之疏漏谬误,须对初步认定的主症特点,深人辨析,理出证候初步轮廓,然后从尚未纳入主症范围之四诊素材中寻求对主症初步印象之支持。同时,要特别重视与主症初步印象不相符合或甚至截然相反之四诊素材,务必仔细分析其形成之病因、病机及诊断意义,取得合理解释,则相应不悖。如与初步印象不相协调,或别出机杼,则应引起重视,认真推敲,去伪存真。若不能排除为假象,当扩展思路,重新进行全面分析和认识。
乙亥(1995年)春夏之交,余诊一男子,年方半百开外。自诉初得病时,时值仲夏,已是单衣时节,患者身穿绒装,犹自畏寒不止,测量体温并不升高,及至盛夏,此症始消。此后频年以来寒热常作,但体温并不甚高,每在37.2~38.5℃之间。往昔感冒发热,一药便愈,今则屡药不效,不得已须静滴葡萄糖液始能退热。但热退后自觉骨中蒸热仍存,终日有昏沉之感。入夜必盗汗见于胸背。咳嗽发于夜半,白昼则较稀。咳嗽特点为喉中作痒梗痛则咳,痒甚每致呛急,可见痰中带血,并曾两次大口吐出暗紫色血液。一年内曾作两次胸透,除“肺门纹理增深”而外,悉属正常。诊断之初步意见为“老慢支?发热待查”。断续服药两年末见效机。余诊见脉小弦,舌质淡红,苔薄白,余症一如前述?于是分析证候:其患者主症中发热、咳嗽二症似属外感,却无畏寒、流涕、咽痛、恶风等外感症状,显非外感可知。发热特点为体温不高,但反复发作,用解表退热药及抗生素效果不佳。此等发热不具外感及阳性炎症发热特征,却呈慢性久病特点。热退后有骨蒸现象,此热当虑为阴虚潮热。咳嗽夜甚昼轻,于咳无痰,喉中作痒则咳,为肺阴亏损、木火刑金。加上盗汗、咯血,已具肺痨四大主证(咳嗽、咯血、潮热、盗汗)。脉象舌苔亦与此推断相应不悖,故此病首当考虑为肺痨病,阴亏火旺证。两度胸透未见病灶,可能与机器性能有关,改摄胸片,明确显示右上肺结核。给予对证治疗,病渐向愈。
对于症状不典型,难以分析代表疾病本质之主症者,当从其病史、体质、发病之气候、环境、服药机变等相关因素,加以分析推理,透过现象,把握本质。

Content Summary
This book is a collection of selected clinical experiences and theoretical insights from the author's thirty years of clinical practice. The entire work consists of eighty-one articles divided into nine parts. It includes verified cases for treating difficult and miscellaneous diseases; frequently effective standard prescriptions; unique pulse diagnosis methods; and personal reflections on treating cancer. Particularly, for conditions such as herpes zoster, acute appendicitis, cerebral concussion, and cerebral contusion, the author diligently seeks guidance from ancient teachings, applying them to modern contexts. For malignant tumors, sequelae of stroke, facial nerve paralysis, pulmonary tuberculosis, schizophrenia, atrial fibrillation, hyperthyroidism, allergic dermatitis, asthma, and other diseases, the author draws upon numerous prescriptions, discards the outdated, and introduces the new, achieving significant results. These are unreservedly presented to readers in relevant chapters. The book is rich in content and concise in style, offering high reference value for TCM clinicians, educators, and researchers.
Preface I
Cao Mengde once recited these famous lines: "The old steed in the stable still aspires to gallop a thousand li; the hero in his twilight years still harbors an indomitable spirit." As someone who has cultivated the medical field for decades, summarizing one's clinical experience and academic theory to contribute to human health and the development of TCM academia is both my wish and my responsibility. However, due to being constantly overwhelmed by clinical duties and having reached the age of eighty with declining energy, my manuscript has remained unfinished for many years.
Now, Mengcheng has surpassed others through his own efforts. He is my student, one of the outstanding among my many students. Through decades of diligent and tireless pursuit and effort, he has achieved gratifying results. *Record of Exploration and Research in Thirty Years of Clinical Practice* not only embodies his concentrated academic experience but also serves as a report of achievements to the motherland and its people. Mengcheng is a person who is diligent without slackening and never satisfied with his learning. He holds great respect for his teachers, memorizing even their briefest instructions. Therefore, the content of the book naturally reveals his transmission relationship with various masters.
In my personal view, this work of Mengcheng has five characteristics: First, rigorous attitude and reliable data. Whether in scholarship or conduct, Mengcheng has always been rigorous, adhering to seeking truth from facts and avoiding hypocrisy and superficiality. Before writing, he followed up directly or indirectly on all cases involved in this book. Only when the efficacy was definite did he use them as data. Moreover, the plain language throughout the book reflects his rigorous spirit from another perspective.
Second, precise syndrome differentiation and meticulous attention to detail. For example, in Article 13 "Complications Arising from Mismedication for Exterior Wind-Heat," Shen suffered from fever and mental confusion, which was differentiated as wind-heat combined with phlegm damaging body fluids. He recovered after modification using Jiajian Weirui Tang (Modified Polygonatum Decoction). Similarly, severe fright cases were treated with tonification; cerebral contusion with calming liver and extinguishing wind; pediatric pneumonia with clearing intestines and draining heat; and atrial fibrillation with nourishing heart and calming spirit. The syndrome-based treatment of these numerous cases was relatively refined and accurate, thus achieving high efficacy.
Third, concise prescriptions and light, agile medication. Many unique verified prescriptions in the book use extremely simple ingredients, often relying on single herbs for effect, which is a very important characteristic. Fewer yet more precise ingredients confront the disease directly, often achieving unexpected success, while avoiding the drawback of mutual restraint among drugs in compound formulas. For instance, using single herb Daihe Shi (Hematitum) for cerebral concussion, wine-decocted Hong Teng (Sargentodoxae Caulis) for acute and chronic appendicitis, and frosted Sang Ye (Mori Folium) decoction for washing conjunctivitis, all exhibit concise efficiency and rapid cure. Meanwhile, when using compound formulas, dosages are often lighter. Case observations show that the expected therapeutic effects were still achieved. This is a valuable application attempt that reduces the impact of drugs on the patient's body and saves medicinal materials, possessing value for further experimental research.
Fourth, deep investigation and creation of new prescriptions. Four special prescriptions used in the book—"Pianku Jianquan Tang" (Paraplegia Recovery Decoction) for rehabilitating hemiplegia from stroke; "Shengyu Zhengrong Tang" (Shengyu Face-Correcting Decoction) for correcting facial nerve paralysis; "Zhen Gan Di Tan Tang" (Calming Liver and Washing Phlegm Decoction) for treating schizophrenia; and "Baihe Changfei Yin" (Lily Lung-Unblocking Drink) for eliminating chronic bronchitis—are all new prescriptions created by Mengcheng after years of clinical experimental research. They often achieve expected effects when treating indicated conditions. This is another important contribution to Chinese medicine.
At the same time, other prescriptions and methods introduced in the book also possess characteristics of simplicity, high efficiency, and reproducibility, making them worthy of promotion and application.
Fifth, comprehensive consideration and practice of holistic equilibrium therapy. "Holistic Equilibrium Therapy" is a treatment principle that Mengcheng has consistently adhered to and continuously explored over a long period, showing special efficacy in treating chronic, persistent, and complex difficult and miscellaneous diseases.
This viewpoint is not explicitly stated in the book because it is currently still in gestation and not yet mature. However, the process of syndrome differentiation and treatment in many complex cases in the book consistently embodies this point. "Holistic Equilibrium Treatment" is an innovation in Mengcheng's academic views. Although similar academic thoughts exist in the works of ancient sages, they are mostly scattered and preliminary, lacking sublimation and crystallization. Guided by the spirit of inheritance and development, Mengcheng is conducting in-depth research. This line of thought and method is already vividly apparent between the lines of this book. Readers with keen insight will surely find resonance.
Mengcheng possesses a spirit of forging ahead in his career. After thirty years of unusual practice and research, he has finally achieved today's success. "Guard against arrogance and rashness, make persistent efforts, and strive for greater achievements!" This is my encouragement and expectation for Mengcheng.

Preface II
I left my motherland and Shanghai to study in the United States and subsequently practiced medicine there for exactly ten years. During this period, I often recalled my relatives and friends in Shanghai. Mengcheng was a classmate and close friend with whom I studied medicine in Shanghai in my early years. Academically, whether in theory or practice, he has always been a person striving tirelessly. Seeing his first book, *Record of Exploration and Research in Thirty Years of Clinical Practice*, makes me very happy, so I am excited to write this preface.
In the colorful garden of our motherland's medicine, rare flowers and grasses can be found everywhere; if you know how to collect them, you will certainly reap rewards. *Record of Exploration and Research in Thirty Years of Clinical Practice* is a collection of Mengcheng's partial clinical insights over several decades and a small display of gathering treasures in the medical garden. "Spring colors cannot be contained within the garden; a branch of red apricot leans over the wall." It is not only a good book that integrates principles, methods, prescriptions, and herbs but also unreservedly exposes his experience to readers and the medical community. This precious spirit moves me deeply. Judging from the content, it focuses on medical technology. However, as the book states, modern medicine defines health as including both physiological and psychological aspects, with the feedback and influence of psychology increasingly showing important roles.
"The formless governs the power of intention" is a bold attempt by the author to apply traditional Chinese medical theory to study psychological feedback phenomena in the medical field, which is very meaningful. Self-cultivation and perfection of the mind are the best ways and methods for people to obtain a healthy psyche, and mental health is an effective prerequisite and guarantee for physical health. Only through long-term training of constantly overcoming and replacing unhealthy psychology with healthy psychology can one reach a noble psychological realm, thereby enjoying the fruits of physical health and longevity. Our motherland's medicine has stepped out of the country and entered the golden hall of world medicine. It is a brilliant pearl that will inevitably make significant contributions to human health. On this occasion, I wish that Mengcheng's work would shine brightly and remain evergreen.

Self-Preface
I have loved Qi-Huang studies (TCM) since childhood. In my youth, living in my hometown, my mother suffered from sudden severe epigastric pain and vomited blood filling a basin. Although medicines were administered repeatedly, there was little effect. At this moment of helplessness and dilemma, my aunt invited the nearby famous doctor Mr. Zou Yunxiang. At that time, Mr. Yunxiang had not yet taken office in Nanjing. He asked about symptoms and felt the pulse, remaining calm and composed. After the diagnosis, he instructed: "Taking Ginseng powder will surely stop the bleeding." Following this method, improvement was seen in one day, and bleeding stopped in three days. Subsequently, after slight regulation, the epigastric pain resolved, and everything became peaceful thereafter. Seeing the miraculous skill of the master, I felt increased reverence and admiration. Observing that many relatives, friends, and neighbors were ill and urgently needed medical treatment, and seeing my grandmother suffer from senile dementia until her death without treatment, Mengcheng often felt sorrowful resolve, firmly establishing the ambition to study medicine. Only after practicing medicine for years did I realize that the profound subtleties of the medical way are not accessible to those who merely scratch the surface. Moreover, possessing a dull nature, I had not penetrated the core essentials of Xuanyuan and Qibo. Lacking divine, sacred, skilled, and clever abilities, I feared that even one mistake among a thousand considerations might bring disaster to others. Therefore, I diligently sought ancient teachings, extensively collected prescriptions, analyzed and dissected them, discarded shortcomings, and utilized strengths. Whenever I had some understanding, I wrote it down for future reference. Over tens of years, notes accumulated to a foot in height. This was still insufficient; I desired to carry my luggage to famous schools and widely seek the heart-to-heart transmission from various masters. Thus, I became a disciple of Mr. Wu Zhutian and received earnest teachings from Professor Jiang Chunhua for twelve years. Furthermore, introduced by Master Wu, I attended consultations with Mr. Yang Yongxuan to learn acupuncture. From this, I received extensive education, covering principles, methods, prescriptions, and herbs, and gained much experiential knowledge. Alas, Mengcheng's capacity is narrow, unable to absorb everything comprehensively. Recently, urged frequently by friends and feeling the sense of twilight in myself, I slightly organized my notes, selected parts, compiled them into a volume, hence the creation of this book.
This compilation originally belonged to casual records for self-reference, not for writing books to establish theories. Therefore, the style of each article varies, and the format is indefinite. No fundamental changes were made during this organization. I merely strive to offer true data and insights to readers and share them with enthusiasts. How much is worthwhile remains for later generations to judge. If even fragments hold meaning, I hope everyone follows the teachings of *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold), saving the suffering of the people with a great compassionate heart, serving patients wholeheartedly. If this can be done, then Mengcheng's wish is fulfilled. Errors are inevitable in the book; if corrected, I would be extremely fortunate.
During the compilation of this book, Comrade Liu Luhai, Comrade Wang Guoxian, and various masters and friends provided much concern and support. Hereby, I express my gratitude!

Discussions on Writing
Clinical Practice Requires Distinguishing Similarities and Differences
Treating diseases prioritizes recognizing syndromes, which is a consistent consensus among physicians of all dynasties. As *Linzheng Zhinan* (Guide to Clinical Practice) states: "The medical way lies in recognizing syndromes, establishing laws, and using prescriptions; these are the three key points," "Among the three, recognizing syndromes is particularly crucial." The key to recognizing syndromes lies in syndrome differentiation. What is syndrome differentiation? The term "syndrome" refers to a concept reflecting the essence of a certain stage of a disease during its occurrence and development. Syndrome differentiation is based on comprehensively collecting material from the four diagnostic methods, applying basic theories such as the four diagnostics, eight principles, zang-fu organs, etiology, and pathogenesis, to analyze, reason, and synthesize judgments, thereby deriving a relatively reasonable syndrome diagnosis. However, due to factors such as the patient's constitution, chronic diseases, severity of illness, emotions, variations in medication response, missed or incorrect treatments, as well as environmental, climatic, and regional factors, the syndrome condition often becomes intricate, presenting approximate, similar, or pseudo-similar syndromes that confuse perception, making it difficult for physicians to diagnose accurately at once, distinguishing true from false. A slight oversight leads one into a fog. For example, extreme yin excess repelling yang outward may present with red face, red eyes, cracked lips and tongue, waving hands and kicking feet, and delirious speech—a scene of fire and heat. Initially appearing as a yang syndrome, it is actually internal true cold with external false heat. Extreme yang heat repelling yin inward may present with cold limbs, deeper heat leading to deeper cold, rigid lying like a corpse, no drinking or eating, no breath from mouth and nose, and cold extremities—a scene of yin cold. Initially appearing as a yin syndrome, it is actually internal true heat with external false cold. Similarly, cancer patients may have solid pulses despite solid evidence, commonly showing limb lethargy, dizziness, blurred vision, poor appetite, and mental fatigue, seeming like a deficiency syndrome; whereas those with middle qi injury from overwork may show epigastric and abdominal distension, discomfort after eating, qi stagnation, and imperfect bowel movements, seeming like an excess syndrome. The above are merely a few examples; in clinical practice, the number of similar/different syndromes is too numerous to recount. Thus, Li Shicai sighed, "All kinds of similar/different symptoms cannot be counted one by one." And Lin Peiqin said in the preface of *Leizheng Zaican* (Compendium of Differentiated Treatments): "The difficulty of life-saving lies in recognizing syndromes; the difficulty of recognizing syndromes lies in differentiation," "Moreover, regarding one symptom, complexities and similarities arise." Therefore, distinguishing true from false and analyzing similarities/differences is an indispensable major link in syndrome differentiation.
Because the main basis for syndrome differentiation is the various materials obtained from the four diagnostics, analyzing similarities/differences must also start from deeply and meticulously analyzing and comparing such materials. Based on my shallow understanding, emphasis seems to be placed on analyzing chief symptoms, pulse qualities, and tongue appearances.
One: Distinguish Chief Symptom Characteristics, Deduce Differences Within Similarities. Syndrome differentiation applies TCM basic theories to analyze, screen, classify, and arrange material from the four diagnostics (inspection, auscultation/olfaction, inquiry, palpation), then summarize and integrate, starting from identifying the chief symptom. The ability to correctly select and identify the chief symptom is an important marker of correct syndrome differentiation. Incorrect selection of the chief symptom often leads to erroneous syndrome diagnosis.
To prevent omissions and errors in identifying chief symptoms, one must deeply analyze the characteristics of the preliminarily identified chief symptom, outline the preliminary syndrome profile, and then seek support for the initial impression of the chief symptom from diagnostic materials not yet included in the chief symptom scope. Simultaneously, special attention must be paid to diagnostic materials that do not match or are even completely opposite to the initial impression of the chief symptom. One must carefully analyze their etiology, pathogenesis, and diagnostic significance to obtain a reasonable explanation, ensuring consistency. If inconsistent or divergent, it should attract attention, be seriously pondered, and stripped of falsehood to retain truth. If false images cannot be excluded, one should expand thinking and re-conduct comprehensive analysis and understanding.
In the transition between spring and summer of the Yihai year (1995), I diagnosed a man in his fifties. He reported that when he first fell ill, it was midsummer, a time for wearing thin clothes, yet he wore woolen clothing and continued to feel aversion to cold. His measured temperature did not rise. This symptom persisted until midsummer before subsiding. Since then, for several years, chills and fever occurred frequently, but the temperature was not very high, usually between 37.2°C and 38.5°C. Previously, a single dose of medicine cured common cold fever; now, repeated medications were ineffective, necessitating intravenous glucose infusion to reduce fever. However, after the fever subsided, he felt steaming heat in the bones remained, accompanied by a sense of drowsiness all day. Night sweats appeared on the chest and back every night. Coughing started at midnight and was less frequent during the day. The characteristic of the cough was itching and soreness in the throat triggering coughing; severe itching often caused choking urgency, sometimes with blood in sputum, and he twice expectorated large amounts of dark purple blood. Two chest fluoroscopies within one year showed nothing abnormal except "deepened hilar markings." The preliminary diagnostic opinion was "Chronic Bronchitis? Fever under investigation." Medication was intermittent for two years without effect. My diagnosis revealed a small wiry pulse, pale red tongue body, thin white coating, and other symptoms as described above. Thus, I analyzed the syndrome: Among the patient's chief symptoms, fever and cough seemed to belong to exterior contraction, yet there were no exterior symptoms such as aversion to cold, runny nose, sore throat, or aversion to wind, clearly indicating it was not an exterior contraction. The characteristic of the fever was low temperature but recurrent episodes, with poor response to exterior-releasing antipyretics and antibiotics. This type of fever lacked features of exterior contraction and positive inflammatory fever, instead presenting characteristics of chronic long-standing illness. The bone-steaming phenomenon after fever subsided suggested this heat should be considered yin-deficiency tidal fever. Cough worse at night and lighter during the day, dry cough without phlegm, and throat itching triggering cough indicated lung yin deficiency and wood-fire insulting metal. Combined with night sweats and hemoptysis, the four chief signs of Pulmonary Tuberculosis (cough, hemoptysis, tidal fever, night sweats) were present. Pulse and tongue appearance were consistent with this inference. Therefore, this disease should primarily be considered Pulmonary Tuberculosis, yin deficiency with fire hyperactivity syndrome.
