RESUMO
Professor ZHANG Boli believed that the core pathogenesis of heart failure with preserved ejection fraction （HFpEF） is weak pulse at yang and wiry pulse at yin. By referring to the theory of “damp-turbidity and phlegm-rheum type of diseases”， he proposed that yin pathogens of damp-turbidity and phlegm-rheum may damage yang qi in each stage of HFpEF， thus aggravating the trend of weak pulse at yang and wiry pulse at yin， which played an important role in the deterioration of HFpEF. Therefore， Professor ZHANG Boli advocated that importance should be attached to the elimination of yin pathogen and the protection of yang qi during the various stages of HFpEF in order to delay the aggravation of weak pulse at yang and wiry pulse at yin； he put forward the idea of staged treatment that “yin pathogen should be dispelled and yang qi should be demonstrated”； and he formulated the treatment strategy of treating the disease as early as possible， eliminating pathogens and protecting yang， interrupting the disease trend， using warm-like medicinals， and activating blood circulation， to enrich the theoretical system of traditional Chinese medicine in the treatment of HFpEF.
RESUMO
Wiry pulse is one of the common pulse tracings, which was recorded firstly in Inner Canon of Huangdi. Most of the modern textbooks of diagnostics of TCM consider that it relates with liver-gallbladder diseases, ache and phlegm-fluid retention,etc. However, there was not record of stringy pulse relating with liver-gallbladder diseases in Treatise on Cold Pathogenic Diseases. From the original of ZHANG Zhong-jing, this article researched the author’s object of discussing stringy pulse, which can be induced as three aspects: diagnosing diseases, analysing pathogenesis and deducing prognosis. The anticle maybe benefi ted to clinical work of TCM.
