OBJECTIVE: To discuss the development status of meridian diagnosis technology through the patent analysis, so as to obtain the hot spots of patents and provide the ideas for the research and development of new equipment. METHODS: The patent data of meridian diagnosis technology were searched from Chinese Think Tank of Traditional Chinese Medicine. The patent analysis and SWOT method were used to deeply explore the patent application of meridian diagnosis technology. RESULTS: Among 100 patents included, the inventions were mainly in Chinese mainland, and the invention institution was from Chengdu University of TCM. Since 2015, the number of patent application for meridian diagnosis technology was increasing, and up to a peak from 2020 to 2021. The main technological programs cover electrical, temperature and optical detection; and the application functions focus on the precise positioning of acupoints, and the diagnosis of zangfu diseases. CONCLUSION From the perspective of patents, it is suggested that the development of meridian diagnosis technology in China should pay attention to reducing the cost, improving the function, driving the standard formulation, strengthening safety measure, deepening human-machine interaction, exploring biological effect and optimizing the experimental platform. Through continuous innovation and breakthrough, the meridian diagnosis technology can be further matured and widely applied, so as to realize its comprehensive upgrade.

OBJECTIVE: To explore the dose-effect relationship between the number of acupuncture sessions and the efficacy for cervical vertigo (CV). METHODS: Literature regarding randomized controlled trials (RCTs) of acupuncture for CV was retrieved from CNKI, Wanfang, VIP, Web of Science, and PubMed databases from inception to June 28th, 2024. Studies were included if patients were treated solely with acupuncture and the core prescription included Baihui (GV20)-Fengchi (GB20)-neck-jiaji (EX-B2). Outcomes included the evaluation scale for cervical vertigo symptoms and function (ESCV) score and the mean blood flow velocity of vertebrobasilar arteries. The Cochrane risk of bias assessment tool 2.0 was used to evaluate study quality. Dose-effect Meta-regression analysis was performed using the robust-error Meta-regression (REMR) method in Stata 17.0 software. RESULTS: Nineteen RCTs were included with a total of 747 patients in the experimental groups. After 10 sessions of acupuncture, the ESCV score increased to 20.29 (95% CI: 16.77, 23.80), with a pre-post ESCV difference of 4.60 (95% CI: 2.59, 6.60) and an improvement rate of 0.36 (95% CI: 0.26, 0.46). After 20 sessions of acupuncture, the ESCV score increased to 21.55 (95% CI: 18.87, 24.22), with a difference of 5.42 (95% CI: 3.87, 6.97) and an improvement rate of 0.39 (95% CI: 0.31, 0.48). After 10 sessions of acupuncture, the improvement rates for left vertebral artery (LVA), right vertebral artery (RVA), and basilar artery (BA) mean blood flow velocities were 0.08 (95% CI: 0.05, 0.12), 0.09 (95% CI: 0.05, 0.12), and 0.11 (95% CI: 0.06, 0.15), respectively. After 14 sessions of acupuncture, the improvement rates reached their peaks: LVA [0.09 (95% CI: 0.06, 0.12)], RVA [0.10 (95% CI: 0.07, 0.13)], and BA [0.12 (95% CI: 0.07, 0.16)]. CONCLUSION A nonlinear dose-effect relationship existed between the number of acupuncture sessions and the efficacy for CV. Fourteen sessions were recommended as the optimal number of acupuncture treatments.
