基于“脾为生痰之源、肺为贮痰之器”论培土生金法在肺癌咳嗽治疗中的应用

Application of Strengthening Earth to Generate Metal Therapy for Lung Cancer Cough Based on the Theory of “Spleen as Phlegm Source and Lung as Phlegm Reservoir”

摘要: 肺癌作为全球发病率和死亡率最高的恶性肿瘤，咳嗽是其最常见的伴随症状之一，严重降低患者生活质量。中医“脾为生痰之源、肺为贮痰之器”理论揭示了痰饮生成与贮藏的核心病机。本文基于该经典理论，系统探讨培土生金法(健脾以绝生痰之源、益气以充肺金之本)在肺癌咳嗽治疗中的理论依据、临床应用及阶段化策略。研究认为，肺癌患者因手术、放化疗、情志抑郁等因素导致脾失健运、水湿停聚，聚湿成痰上贮于肺，引发咳嗽咳痰、气短乏力等症。培土生金法通过恢复脾运功能、充养肺气，标本兼顾，是现代肺癌咳嗽症状管理中不可或缺的中医治疗策略。

Abstract: Lung cancer ranks first in terms of incidence and mortality worldwide among all malignant tumors. Cough is one of its most common accompanying symptoms, which seriously impairs patients’ quality of life. The traditional Chinese medicine (TCM) theory that “the spleen is the source of phlegm production, and the lung is the container storing phlegm” reveals the core pathogenesis of the generation and accumulation of phlegm-fluid. Based on this classical theory, this paper systematically discusses the theoretical basis, clinical application and staged strategies of the method of strengthening earth to generate metal (invigorating the spleen to cut off the source of phlegm production, tonifying qi to enrich the root of lung metal) in the treatment of cough in lung cancer. The study holds that lung cancer patients may suffer from impaired spleen transportation, retention of water-dampness, and phlegm accumulated in the lung due to surgery, radiotherapy and chemotherapy, emotional depression and other factors, leading to symptoms such as cough with expectoration, shortness of breath and lassitude. By restoring the transporting function of the spleen and nourishing lung qi, the method of strengthening earth to generate metal addresses both the root cause and symptoms, serving as an indispensable TCM therapeutic strategy for modern symptom management of cough in lung cancer.
