基于“血水相关”辨治糖尿病肾病的 “虚热湿瘀”病机探讨

Discussion on the Pathogenesis of “Deficiency, Heat, Dampness and Stasis” in Diabetic Nephropathy Based on the Theory of “Correlation between Blood and Water”

摘要: 本研究通过理论阐释与文献梳理，以中医“血水相关”学说为切入点，深入剖析糖尿病肾病(DN)“虚、热、湿、瘀”四大核心病理机制的内在联系。依据疾病发展过程中血水失衡的主次矛盾，构建了“血水同治”的分期诊疗体系，旨在为临床实践提供理论支撑。针对DN复杂的致病过程，“血水理论”提供了关键的解读视角。该病的根本源于脾肾两虚(虚)；正气亏损致使水饮内停(湿)；水湿久滞则郁而发热(热)；最终酿成血水交结、肾络瘀阻(瘀)。这四大因素相互胶结，共同构成了DN的基础病理状态。随着病情进展，上述病机呈现出明显的动态演变规律。早期主要表现为“水病为先”，治宜健脾化气、利水兼以和血。中期逐渐发展成“血水同病”，此时须扶正与祛邪并举，采取益气养阴补血，或温阳活血利水之法。及至晚期，“血病入络”成为主导，治疗重心应转向温阳降浊与化瘀通络，并辅以利水。在方药应用上，桂枝茯苓丸便是践行“活血、利水、调气”同治理念的典型代表。综上所述，以“血水理论”指导DN治疗，不仅能精准把握病机本质，其衍生出的分期策略更具备极高的临床实用价值。后续亟待引入现代科技手段深化其微观机制的研究，并依托高质量的临床试验来验证相关方剂的确切疗效。

Abstract: Through theoretical interpretation and literature review, this study takes the traditional Chinese medical theory of “correlation between blood and water” as a breakthrough point to deeply analyze the internal connections among the four core pathological mechanisms of “deficiency, heat, dampness and stasis” in diabetic nephropathy (DN). Based on the primary and secondary contradictions of blood-water imbalance during disease progression, this study constructs a staged diagnosis and treatment system based on the principle of “simultaneous treatment of blood and water”, aiming to provide theoretical support for clinical practice. The “blood-water theory” offers a crucial interpretive perspective for the complex pathogenesis of DN. The fundamental cause of the disease lies in the deficiency of both spleen and kidney (deficiency); the deficiency of healthy qi leads to the internal retention of water-fluid (dampness); prolonged stagnation of water-dampness transforms into heat after depression (heat); and eventually results in the entanglement of blood and water and the obstruction of renal collaterals by blood stasis (stasis). These four pathogenic factors interact and intertwine with each other, jointly forming the basic pathological state of DN. With the progression of the disease, the above-mentioned pathogenesis presents an obvious dynamic evolution law. In the early stage, the main manifestation is “water disease as the priority”, and the treatment should focus on invigorating spleen and regulating qi, promoting diuresis and harmonizing blood. In the middle stage, it gradually develops into “concurrent disease of both blood and water”, at which time both strengthening healthy qi and eliminating pathogenic factors should be implemented, and the methods of supplementing qi, nourishing yin and tonifying blood, or warming yang, activating blood and promoting diuresis should be adopted. In the late stage, “blood disease entering collaterals” becomes dominant, and the therapeutic focus should be shifted to warming yang for descending turbidness, removing stasis and unblocking collaterals, supplemented by promoting diuresis. In terms of prescription application, Guizhi Fuling Wan is a typical representative that implements the therapeutic concept of simultaneous treatment of “activating blood, promoting diuresis and regulating qi”. In conclusion, guiding the treatment of DN with the “blood-water theory” can not only accurately grasp the essence of pathogenesis, but also the derived staging strategy has extremely high clinical practical value. It is urgent to introduce modern scientific and technological means to deepen the research on its microcosmic mechanism, and rely on high-quality clinical trials to verify the exact efficacy of related prescriptions.
