By analyzing the understandings of water points (acupoints connected with the kidney) and its association with water (kidney), zangfu organs and meridian-collateral recorded in Suwen: Shuire Xue Lun (Discussion on Water and Heat Diseases in Plain Question), it is found that the recognition on the water points is different from that on water diseases in Huangdi Neijing (the Yellow Emperor 's Inner Classic). The recognition on the water points focuses on the core theory, "rooted at the kidney", to explain the water diseases. Besides, in association with the study on the connotation of "luo" in Huangdi Neijing, it is discovered that "yinluo" discussed in water points is actually the misunderstanding of "zang zhi yinluo" that means "the connection by the kidney". It is shown that the discussion of water points refer to the elaboration of zangfu organs and 57 acupoints connected with water (the kidney), rather than the theory of collaterals. The characteristics of these 57 acupoints involved and the related needling techniques provide a new approach to the treatment of zangfu diseases.

The paper reviews the evolution of the theory related to meridians and zangfu organs during the Warring States, Qin and Han dynasties, so as to reveal the rules and value of its development. By analyzing historical documents, especially Zubi Shiyimai Jiujing (Moxibustion Classics of Eleven Meridians of Legs and Arms), Yinyang Shiyimai Jiujing (Moxibustion Classic on Eleven Yin and Yang Meridians), Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the evolutionary stages, i.e. the germination, development, and maturity of meridian-zangfu theory, are explored. In the time of the Warring States, Qin and Han dynasties, the meridian-zangfu related theory was developed from the germination to the maturity. In the classics of the early time, Zubi Shiyimai Jiujing and Yinyang Shiyimai Jiujing demonstrated the preliminary relationship between meridians and zangfu organs, focusing on the physiological connection and pathogenesis of three yin meridians of foot and zangfu organs. In the literature of Laoguanshan bamboo medical slips of Han Dynasty and lacquer figure of meridian points, the physiological connection between the yin meridians of hand and foot, and five zang organs, as well as the related diseases were further clarified; additionally, the meridian-zangfu theory had been developed in the field of diagnosis and treatment. In the era of Chapter of Meridians in Lingshu (Miraculous Pivot), there were up to 31 descriptions relevant with the connection of meridian distribution and zangfu physiological functions. It marks the construction of the "circular" flow of meridians and the interior-exterior communication of zang and fu organs; and enriches the knowledge in diseases, diagnosis and treatment with meridians and zangfu organs involved. The review on the evolution of the meridian-zangfu theory is conductive to supplementing and improving the development history of this theory of early time, and further recognizing its development rules and value. The maturity of this theoretical system not only links the meridians with the five zang and six fu organs, but also provides an important theoretical basis for the diagnosis and treatment of traditional Chinese medicine.

In Weisheng Baojian (Treasures on Health), the compatibility of Qihai (CV6) and Zusanli (ST36) was widely used in the medical cases treated with acupuncture and moxibustion. Through analyzing the medical cases and summarizing the rules of acupoint compatibility, it is found that LUO Tianyi's idea of moxibustion at these two acupoints was different from the other medical masters. He combined these two acupoints in line with "spleen and stomach theory", rather than from the perspective of the direct relationship of acupoints with syndromes and zangfu organs. It reflects the diversity in the understanding of the human body and diseases among medical masters. Therefore, in order to analyze the representative understandings of ancient medical masters on the connotation and rules of acupuncture and moxibustion, we cannot simply focus on the summary from acupuncture-moxibustion masters. It is suggested that the analysis should be expended in the entire field of traditional Chinese medicine to explore the general rules of treatment with acupuncture and moxibustion, investigate the differences, and deepen the basic reasons of the distinction.

Zangxiang Jingmai Yuanliu Zeyin (Exploration of Origin and Development of Visceral Manifestations and Meridians) traces the historical origin for the development of the theories of visceral manifestation and meridians and in terms of the guiding principles and cultural background of these theories structured by the ancients. It chains the clues of the related knowledge development in Huangdi Neijing (the Yellow Emperor's Inner Classic) based on the rich historic literature. By interpreting the classics through history and in view of the specific humanistic perspective, the book exhibits the non-linear evolution track of the theoretical knowledge of visceral manifestation and meridians in the pre-Qin and Han dynasties. It is an important works in the field of acupuncture and humanities, and enlightens the cross-exploration of acupuncture, even in the circle of academic study of TCM and the humanities.

Zangxiang Jingmai Yuanliu Zeyin (Exploration of Origin and Development of Visceral Manifestation and Meridians) reveals that the theory of visceral manifestation and meridians of TCM is evolved with Tiandao (way of heaven) in different periods of ancient times. In the Warring States period, the "way of heaven" referred to yinyang and four directions, based on which, the manifestation of four viscera was developed. During the Qin and Han dynasties, six meridians were developed on the basis of six types of qi. In terms of "six types of qi and five elements", five zang, six fu and eleven meridians were structured in TCM. Corresponding to the twelve cycles of the ecliptic and celestial sphere, twelve meridians were composed. The book displays a particular style of research with rich quotations, and provides a new way of thinking for the study of ancient TCM books.

Through the investigation of relevant literature, the concepts, methods, languages and tools of ontology were explored, and the suitable methods and tools for the ontology construction of acupoint anatomy were selected. The current mainstream anatomical ontology and related ontology of TCM were investigated so as to provide the reference for the ontology construction of acupoint anatomy. According to the knowledge attributes of acupoint anatomy, the foundational model of anatomy (FMA) was served as the reusable ontology, and in association with the attribute classification of traditional Chinese medicine language system (TCMLS), the construction approach to acupoint anatomical ontology was explored. By taking "anatomical entity of acupoints" as the top-level concept, the demonstrative study on the anatomical ontology construction was conducted on the acupoints of lung meridian of hand-taiyin.

Several metal needles were unearthed from the tomb of LIU He, the Marquis of Haihun in Nanchang, Jiangxi province. Based on the inscription on the signboard unearthed from the tomb and the handed down literature, these needles should be closely related to the "nine needles" mentioned in the handed down medical classics. These needles should be used in acupuncture and moxibustion at that time, and their diameters are close to the specifications and dimensions of the needles in the modern time, which provides the important cultural relics data of the Han Dynasty for the research of early acupuncture and moxibustion of traditional Chinese medicine. This article uses the method of mutual verification of unearthed cultural relics, unearthed documents, and handed down documents to investigate the acupuncture method of medical needles unearthed from the tomb of Marquis Haihun, and to sort out and demonstrate the development of acupuncture and moxibustion in the Western Han Dynasty. The medical needles unearthed from the tomb of Marquis Haihun and their needling techniques can be confirmed by the "nine needles" in the Lingshu (Miraculous Pivot), the "acupuncture treatment" in the bamboo slips of the Han Dynasty in the Northwest, and the "acupuncture atlas" on the Han portrait stone. It proves that the manufacturing of needles for acupuncture and moxibustion and the therapeutic methods and techniques of acupuncture had been greatly developed in the middle and late stages of the Western Han Dynasty.

Transcutaneous electrical stimulation equipment is a kind of characteristic therapeutic devices developed on the basis of the integration of traditional Chinese medicine (TCM) theory and modern science and technology, which is widely used in clinical practice. Significant breakthroughs have been made in the development of related devices such as transcutaneous electrical acupoint stimulation (TEAS) devices, transcutaneous electrical nerve stimulation (TENS) devices, and transcutaneous auricular vagus nerve stimulation (taVNS) devices in recent years. Although the market for these devices is vast, there are still limitations that need to be optimized in terms of electrode materials and power supply methods, bulky instrument size, cumbersome wiring, restricted applications, and inadequate intelligent functionality. In the future, it is still necessary to further build upon the theoretical foundation of TCM acupuncture, integrate a variety of modern scientific technologies to advance the intelligence and modernization of acupuncture equipment, and thereby improving its capabilities to support clinical practice and research.
