AI Article Synopsis
- The study aimed to analyze the effects of electroacupuncture (EA) stimulation using multiport network theory to explore the pathways of acupuncture meridians in the body.
- Researchers modeled the body as a complex network and conducted experiments on 12 beheaded toads to measure electric signals from stimulated muscles and identify "acupoints."
- Results showed twelve 3D curves of electric signal transfer, indicating that measuring signal transfer coefficients can help map acupuncture meridians in living organisms.
Article Abstract
Objective: To analyze the real-time effects of electroacupuncture (EA) stimulation by means of multiport network theory and measurement of the electric signals transfer coefficient, so as to explore a way for determining the running course of acupuncture meridian and for characterizing its physiological activities in the living body.
Methods: The body was modeled as a complex inhomogeneous 3-dimensions multi-port network, and the meridians were assumed to be "the most smoothly channels for signal transmission". Experiments were performed in 12 beheaded toads whose forelimbs and hindlimbs were divided into proportional coordinates. A concentric electrode with a conical tip was inserted into the toad leg for electrical stimulation of the local muscle, and another electrode alike was inserted into different spots of the limbs to detect the spreading signals in a 3-dimensional scanning mode. Following detecting the response electric voltage values of various spots and calculating their transfer coefficients, the spots which acquired a maximum signal value were considered to be the "acupoints". The imaginary connective lines passing the "acupoints" were regarded as the running courses of acupuncture meridians.
Results: A total of twelve 3-dimensional curves were detected based on the connected lines of electric signal transfer function extremum spots 2 mm beneath the skin of the ipsilateral fore- and hind-limbs of 12 spinal toads.
Conclusion: The present study initially validates the feasibility of electric signal transfer coefficient measurement for displaying the running course of acupuncture meridian in the toad fore- and hindlimbs.

Background: There is a gap in understanding the effects of different acupoints and treatment methods (acupuncture and moxibustion) on microcirculatory changes in the lumbar region.
Objective: This study aimed to assess the thermal effects of acupuncture at Weizhong (BL40), with acupuncture at Chize (LU5) and moxibustion at both acupoints as control interventions.
Design, Setting, Participants And Interventions: In this randomized controlled trial, 140 healthy participants were equally divided into four groups: acupuncture at BL40 (Acu-BL40), acupuncture at LU5 (Acu-LU5), moxibustion at BL40 (Mox-BL40) and moxibustion at LU5 (Mox-LU5).

Purpose: The incidence of Functional Dyspepsia (FD) is gradually increasing, yet there are currently no effective treatment methods available. This study explored the effective components, potential targets, and pathways of Shi-San-Wei-He-Zhong-Wan (SSWHZW) in the treatment of FD, aiming to provide new insights into its treatment.
Methods: First, the Chinese Medicine System Pharmacology Database and Analysis Platform (TCMSP) and GeneCards databases were utilized to identify the major active components of SSWHZW and potential therapeutic targets of FD.

This study aimed to investigate the effects of electroacupuncture (EA) at specific acupoints (DU20 and ST36) and different frequencies (2 and 100 Hz) on brain regions associated with trigeminal neuralgia, anxiety, and depression. Chronic trigeminal neuralgia was induced by the chronic constriction of the infraorbital nerve (CION). Anxiety and depression were assessed through behavioral tests.

Electroacupuncture (EA) is one of the most commonly used methods in acupuncture and has a good effect on pain, depression, sensory movement disorders, and other diseases. The effectiveness of EA is influenced by many factors, such as the accuracy of acupoint selection, the duration and course of EA treatment, and EA parameters. However, it has rarely been discussed whether the positive and negative electrodes of the EA instrument with acupoints at different locations and distances have an effect on the curative effect.
