药品与企业信息
Transcutaneous auricular vagus nerve stimulation is delivered bilaterally using an external stimulator with electrodes placed on auricular regions targeted for vagal innervation (e.g., cymba conchae). Stimulation is applied for approximately 10 minutes. Parameters are standardized (e.g., 25 Hz; pulse width 200-300 microseconds), and current intensity is individually adjusted to a clearly perceptible but non-painful level. The procedure is performed in a single visit with pre- and post-intervention spirometry and physiological monitoring as specified in the protocol.
Sham stimulation uses the same device, setup, and session duration to mimic the active procedure. Electrodes are placed on an ear location intended to minimize vagal activation (e.g., ear lobule), and stimulation is delivered at a minimal/low level to provide a similar sensation without therapeutic vagal stimulation. Pre- and post-session spirometry and other measurements are collected identically to the active arm.

研究简介（原文）
This study will examine the short-term effects of transcutaneous auricular vagus nerve stimulation (a non-invasive electrical stimulation delivered through the outer ear) on lung function measured by spirometry in healthy adults. The vagus nerve is involved in many automatic body functions, and ear-based stimulation has been used in research to explore its possible effects on different physiological systems. However, it is not clear whether a brief stimulation session can acutely influence breathing test results in people without respiratory disease. Healthy volunteers aged 18-40 will take part in one laboratory visit. Participants will be randomly assigned to one of two groups: (1) active bilateral stimulation applied to specific ear regions that are known to be innervated by the vagus nerve, or (2) sham stimulation using the same device setup but designed to minimize vagal activation. The stimulation session will last approximately 10 minutes. Before and after the stimulation, participants will perform standard spirometry (breathing) tests. Primary spirometric outcomes will include common measures of lung function such as forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and peak expiratory flow (PEF). Heart rate, heart rate variability, and blood pressure may also be recorded to monitor physiological responses and safety during the visit. Participation is voluntary and participants may withdraw at any time. The procedure is considered minimal risk. Possible side effects are usually mild and temporary, such as tingling, warmth, or mild discomfort at the ear. Rarely, participants may feel lightheaded; if this occurs, the procedure will be stopped and the participant will be monitored until symptoms resolve. There is no guaranteed direct benefit to participants. The results may help clarify whether short-term ear-based vagus nerve stimulation can influence spirometric parameters and may inform future studies on autonomic and respiratory interactions.

这项试验目前在中国大陆没有研究中心
这种情况下，直接发"入组咨询"往往会被回复"您所在地区没有中心"。更有效的做法是申请同情用药／扩展准入（由主治医生一同提出），或询问能否到最近的境外中心参加。下面已为您切换到对应的信件版本。
