Background: The energy flow at acupuncture point is important for understanding the mechanism of acupuncture treatment. However, there are few studies on energy at acupuncture point, and related studies have limitation in explaining the energy flow in all meridians. Thus, we aimed to understand the properties of electrical energy at acupuncture point in twelve meridians by measuring the biopotential at acupuncture and non-acupuncture points.
Methods: For each meridian, twenty subjects were participated, and biopotential was measured at five transport points and their adjacent non-acupuncture points. In each subject, both 'non-stimulation' and 'stimulation' experiments were conducted in random order. The data were analyzed in two parts: biopotential variability and biopotential difference between acupuncture and non-acupuncture points.
Results: The biopotential variability at acupuncture point was increased by acupuncture stimulation, and it was related to the activation of Qi flow by acupuncture stimulation. The biopotential difference between acupuncture and non-acupuncture points was formed in the direction related to the Qi flow theory, and this biopotential difference tended to decrease by acupuncture stimulation.
Conclusion: The study on biopotential can provide a foundation for research on energy flow mechanism of acupuncture stimulation, and it is expected to overcome limitation of qualitative explanation in traditional medicine.

Gastric ulcer (GU) is a common digestive system disease. Acupuncture, as one of the external treatments of traditional Chinese medicine (TCM), has the characteristics of multi-target, multi-pathway and multi-level action in the treatment of GU. The relationship between meridian points and Zang-fu is an important part of the theory of TCM, which is crucial for the diagnosis and treatment of diseases.

Hypoxia is not uncommon in elderly patients during painless gastrointestinal endoscopy. This study aimed to determine the effectiveness of transcutaneous electrical acupoint stimulation (TEAS) in reducing the occurrence of hypoxia symptoms in elderly patients. Patients were randomly and equally grouped into sham control ( = 109) or TEAS group ( = 109) by using the random number table method.

Surgical treatment includes neurorrhaphy, grafting (allografts and autografts) and tissue-engineered grafting (artificial nerve guide conduits), while non-surgical treatment methods include electrical stimulation, magnetic stimulation, laser phototherapy and administration of nerve growth factors. However, the treatments currently available to best manage the different PNI manifestations remain undetermined.
