Based on Huangdi Neijing (Yellow Emperor\'s Internal Classic), combined with the Huangdi Mingtang Jing JiJiao (Compilation and Correction of Yellow Emperor\'s Mingtang Classic) and unearthed Tianhui Yijian (Tianhui Medical Bamboo Slips), it is recognized that the therapeutic indications of Fenglong (ST 40) were recorded repeatedly in many medical works of the Qin and Han dynasties; and the treatments mostly focus on \"upward reversion of qi \". In Huangdi Mingtang Jing (Yellow Emperor\'s Mingtang Classic), a part of symptoms were re-described textually, which affects the understanding on the indications of Fenglong (ST 40) in the medical works of the later generations. On the basis of the construction of phlegm theory in the Sui and Tang dynasties, the scholars of Song, Jin and Yuan dynasties had placed the emphasis on the relationship between phlegm and qi movement. In acupuncture works by Dou Hanqing, Fenglong (ST 40) was selected in treatment of phlegm dampness and phlegm-induced asthma, which is also based on the pathogenesis, \"upward reversion of qi \", rather than \"phlegm\" itself. This view can be understood by the proof of \"reducing Zusanli (ST 36) for eliminating wind\". The relationship between Fenglong (ST 40) and phlegm was emphasized in Yulong Ge (Jade Dragon Verse) and Zhenfang Liuji (Six Sets of Acupuncture Methods), after which, the understanding, \" Fenglong (ST 40), the key point for phlegm disorders\", had been formed gradually since the Ming dynasty. The formation and evolution of the therapeutic indications of Fenglong (ST 40) are influenced comprehensively by the errors in textual duplication, cultural background, changes in the term expressions of disorders, and the clinical experience of medical practitioners.
基于传世文献《黄帝内经》，结合《黄帝明堂经辑校》以及出土文献《天回医简》，认为秦汉时期诸医籍中丰隆穴主治病症多有重合，且所针对病机多为“气逆”，《黄帝明堂经》对部分症状的文字表述改写后，影响了后世医籍对丰隆穴主治的认识。在隋唐时期痰病理论构建的基础上，宋金元医家重视痰与气机之间的关系，窦汉卿针灸著述中治疗“痰饮”“痰喘”选取丰隆穴，也是针对“气逆”这一病机，并非针对“痰”之本身，且可结合“三里泻之，以去风”佐证。经《玉龙歌》《针方六集》强调丰隆穴与“痰”之间的关系后，自明代以来逐渐形成丰隆为“治痰要穴”这一认识。丰隆穴主治病症的形成与演变受文本传抄讹误、文化背景影响、病症名称表述形式转变以及医家自身临床经验等因素的综合作用。.

Through analyzing the indication distribution of the different acupoints located at the upper limbs recorded in Science of Acupoints and Science of Meridians and Acupoints, the industry planning teaching materials of traditional Chinese medicine, it is discovered that the acupoints located at the upper arms are commonly selected for the treatment of scrofula and goiter, while the acupoints below the elbow at the hand meridians and those at the lower limbs of the foot meridians which running through the neck, do not have the similar indications. Based on a further analysis on the literature at ancient and modern times, it is believed that the acupoints located on the lateral side of the upper arms, especially those at the large intestine meridian of hand-yangming perhaps have the specific effect in treatment of scrofula and goiter.
通过统计中医药行业规划教材《腧穴学》《经络腧穴学》中上肢不同部位腧穴主治病证的分布情况，发现臂部腧穴常有治疗瘰疬、瘿病的记录，而手经中位于肘关节以下的腧穴以及循行过颈的足经的下肢腧穴却少有此类主治作用。基于古今文献进一步分析，认为臂外侧部的腧穴，尤其是手阳明大肠经腧穴，可能具有治疗瘰疬、瘿病的特殊作用。.

The theory that meridians connect the upper and lower, interior and exterior of the whole human body comes from the clinical experience of acupuncture therapy mainly by choosing the acupoints of 12 regular meridians at the four limbs. During the process of merging the theories of meridians and Zangfu-organs (viscera), the expression of the intrinsic relationship of such connection gradually becomes more and more complicated. Therefore, the study on the correlation between the meridian and viscus should start from the characteristics of the meridian theory itself, and discriminate the \"reasonable and unreasonable\" components of the related theoretical descriptions in the literature in order to explore the scientific values of this correlation. Based on this viewpoint, the present article makes a brief analysis on this proposition from the following two angles of view: the understan-ding of such proposition and the historical evolution of the meridian theory.
