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.

Microbial detection and control of traditional Chinese medicine(TCM) decoction pieces are crucial for the quality control of TCM preparations. It is also a key area of research in the measurement technology and equipment development for TCM manufacturing. Guided by TCM manufacturing measurement methodologies, this study presented a design of a novel portable microbial detection device, using Atractylodis Macrocephalae Rhizoma decoction pieces as a demonstration. Immunomagnetic separation technology was employed for specific isolation and labeling of target microorganisms. Enzymatic signal amplification was utilized to convert weak biological signals into colorimetric signals, constructing an optical biosensor. A self-developed smartphone APP was further applied to analyze the colorimetric signals and quantify target concentrations. A portable and automated detection system based on Arduino microcontroller was developed to automatically perform target microbial separation/extraction, as well as mimetic enzyme labeling and catalytic reactions. The developed equipment specifically focuses on the rapid and quantitative microbial analysis of TCM active pharmaceutical ingredients, intermediates in TCM manufacturing, and final TCM products. Experimental results demonstrate that the equipment could detect Salmonella in samples within 2 h, with a detection limit as low as 5.1 × 10~3 CFU·mL~(-1). The equipment enables the rapid detection of microorganisms in TCM decoction pieces, providing a potential technical solution for on-site rapid screening of microbial contamination indicators in TCM. It has broad application prospects in measurement technology for TCM manufacturing and offers strong technical support for the modernization, industrialization, and intelligent development of TCM.
