各种疾病中,失血(大量出血)的脉象必然表现为芤脉(浮大中空,如按葱管)、缓脉、小脉,这是可以欣慰的;若出现数脉(脉搏急促)和大脉,则值得担忧。这句话阐述了失血脉证的含义。凡是失血脉证,如果见到芤象,或者脉象缓小而不足,与病势不相宜(即邪气不盛),这是可喜的现象。如果脉象数而大,说明邪气盛而正气衰,火热灼伤真阴,这确实是值得担忧的情况。
瘀血在体内蓄积,脉象适宜表现为牢脉(沉实弦长)、大脉、沉脉、小脉;若反而出现涩脉(往来艰涩)、微脉(极细极软),则会加重病情。这句话阐述了瘀血脉证的含义。血液蓄积于内,瘀滞不通,脉象应当呈现牢大的特征,这也是因病邪呈露出的象。通过攻逐使瘀血去除,从而生成新血并不难。假如脉象表现为沉、小、涩、微,这是病邪有余而正气不足的体现,反而会成为危害。
遗精和白浊(尿道口流出白色浑浊液体),脉象适宜表现为微、涩、弱;若出现火盛阴虚之象,则见芤脉、濡脉(浮细无力)、洪脉(来盛去衰)、数脉。这句话阐述了精浊脉证的含义。肾主藏精,应当在房事之后才施泄。如今或念头一动即射精,或无欲望而自行遗精,这都是肾虚不能固摄的缘故。白浊是指小便颜色白且浑浊,形态属于精液范畴,证候属于脱亡(精气耗散)。脉象怎能不表现为微涩而弱呢?假如见到芤、濡、洪、数的脉象,芤脉和濡脉固然表示阴虚,但洪脉和数脉实际上是因为火盛,这与肾的虚寒而不能藏精的情况又当区别对待了。
三消(上消、中消、下消三种消渴病)的脉象若为浮大者,预后良好;若为细小、微、涩,形体脱败,令人惊惧。这句话阐述了三消脉病的含义。三消分为上、中、下三焦。口渴多饮为上消;消化食物快、容易饥饿为中消;口渴且小便频数、尿中有膏脂为下消。其脉象若为浮大,说明津液生成而不枯竭,气血调和而不涩滞,尚属可生。若是细小、微、涩,则是气血虚衰、枯槁,形气和神气两败,哪里只是令人惊惧而已呢?
小便淋证(排尿不畅、滴沥不尽),鼻头色黄,脉象涩小而无血象,或脉象数大,这无关紧要。这句话阐述了小便淋证的脉病轻重含义。淋证是指淋沥不尽,闭证是指闭塞不通。这些证候表现为小便少而次数多,小腹拘急疼痛牵引至脐部,这都是肾虚兼膀胱热所致。淋证分为五种:石淋、劳淋、血淋、气淋、膏淋。又有寒淋和热淋两种。寒淋是由于肾气虚弱,下焦受冷,寒气偏胜导致战栗发冷而成淋;热淋是由于三焦有热气,搏结于肾,流入胞宫(此处指膀胱/泌尿系统)而成淋。大抵淋证虽然分各种类型,必定因为劳累导致火起,火盛搏结气机而成。热邪煎熬津液,则水道不利,内热郁蒸而外发黄色,见于鼻头,是因为鼻为肺之窍。脉象涩小,是指涩滞微小而不滑利。征验其正气衰弱且无血象,若见数大为火象,火证出现又有什么妨碍呢?相较于无血(严重失血或极度虚弱),这算是容易治疗的。
In various diseases, the pulse of blood loss (massive hemorrhage) must manifest as a Kou pulse (floating, large, and empty in the middle, like pressing a scallion stalk), a Huan pulse (slow and relaxed), or a Xiao pulse (small); these are auspicious signs. If a Shu pulse (rapid) and Da pulse (large) appear, they are ominous. This statement elucidates the meaning of pulse patterns in blood loss syndromes. In cases of blood loss, if a Kou image is observed, or if the pulse is slow, small, and insufficient, indicating that the pathogenic factor is not severe, this is auspicious. However, if the pulse is rapid and large, it indicates that the pathogenic factor is exuberant while the healthy Qi is deficient, and fire is scorching the true Yin; this is indeed a cause for concern.
When blood stasis accumulates internally, the pulse should ideally be Lao (deep, solid, string-taut, and long), Da, Shen (deep), or Xiao. Conversely, if it manifests as Se (rough and hesitant) or Wei (extremely fine and faint), it will exacerbate the condition. This statement elucidates the meaning of pulse patterns in blood stasis syndromes. When blood accumulates internally and stagnates without flowing, the pulse tends to present as Lao and Da, reflecting the manifestation of the disease. It is not difficult to expel the stasis and generate new blood. However, if the pulse appears as Shen, Xiao, Se, or Wei, it signifies that the pathogenic factor is excessive while the healthy Qi is deficient, which ironically becomes detrimental.
Spermatorrhea and Bai Zhuo (white turbid discharge from the urethra) typically present with Wei (fine), Se, or Ruo (weak) pulses. If there is excess fire and Yin deficiency, the pulse may appear as Kou, Ru (floating and fine and soft), Hong (surging at the beginning and declining at the end), or Shu. This statement elucidates the pulse patterns associated with spermatorrhea and turbidity syndromes. The Kidney stores essence and should only release it during sexual intercourse. Currently, emission occurs upon mere mental arousal or spontaneous leakage without desire; this is due to Kidney deficiency failing to consolidate and retain. Bai Zhuo refers to urine that is white and turbid, belonging morphologically to essence but pathologically representing depletion and loss. How can the pulse not be Wei, Se, and Ruo? If Kou, Ru, Hong, or Shu pulses are observed, Kou and Ru certainly indicate Yin deficiency, but Hong and Shu actually result from excess fire. This differs from the case of Kidney deficiency-cold failing to store essence.
For San Xiao (the three types of Xiao syndrome: thirst-impairment), a Fu (floating) and Da pulse indicates survival, whereas Xi (thin), Xiao, Wei, and Se pulses with physical emaciation are alarming. This statement elucidates the significance of pulse patterns in San Xiao diseases. San Xiao is divided into Upper, Middle, and Lower Jiao. Excessive thirst and drinking characterize Upper Xiao; excessive hunger and digestion characterize Middle Xiao; excessive thirst with frequent urination containing fatty substances characterizes Lower Xiao. If the pulse is Fu and Da, it implies that body fluids are generated and not depleted, and Qi and Blood are harmonious and unobstructed, suggesting a possibility of recovery. If the pulse is Xi, Xiao, Wei, or Se, it indicates the depletion and withering of Qi and Blood, with both form and Qi exhausted; this is far more than just alarming.
Regarding Xiao Bian Lin (dysuria with dribbling), a yellowish nose tip, a Se and Xiao pulse without blood signs, or a Shu and Da pulse are not necessarily problematic. This statement elucidates the severity indicated by pulse patterns in dysuria. Lin syndrome involves dribbling without completion, while Bi syndrome involves complete obstruction. These conditions manifest as scanty and frequent urination, with stiffness and pain in the lower abdomen radiating to the umbilicus, caused by Kidney deficiency combined with Bladder heat. Lin syndrome is categorized into five types: Shi Lin (stone), Lao Lin (labor/fatigue), Xue Lin (blood), Qi Lin (qi), and Gao Lin (fatty). Additionally, there are Han Lin (cold) and Re Lin (heat). Cold Lin arises from Kidney Qi deficiency and cold invading the Lower Jiao, where excess cold causes shivering and leads to Lin. Heat Lin results from heat in the Three Jiao clashing with the Kidney and flowing into the Bao (bladder/uterus). Generally, although Lin syndrome has various types, it is invariably caused by labor-induced fire, where excess fire clashes with Qi. Heat steams body fluids, obstructing the water passages; internal heat stagnates and steams, causing yellow discoloration to emerge externally on the nose, as the nose is the opening of the Lung. A Se and Xiao pulse indicates roughness, minuteness, and lack of smoothness. Observing deficient healthy Qi and absence of blood signs, if a Shu and Da pulse appears indicating fire, what harm does this pose? Compared to the absence of blood (severe deficiency), this is easier to treat.
