在功能性消化不良大鼠，電針足三里（與太衝）顯著改善胃腸蠕動，並上調 GDNF、GFRα1、PI3K、Akt、增加腸神經膠細胞；此研究同時設經穴、非經穴與非穴位對照。
In functional dyspepsia model rats, EA at ST36 (and LR3) significantly improved gastrointestinal motility by increasing enteric glial cells via the GDNF/GFRα1/PI3K/Akt pathway; the design included meridian-point, non-meridian-point and non-acupoint controls.

EA at ST36 activated the cholinergic anti-inflammatory pathway (up-regulated α7nAChR and HO-1, attenuated NF-κBp65 phosphorylation, reduced plasma IL-1β/IL-6/TNF-α, preserved gut-barrier tight junctions); the effect was abrogated by an α7nAChR inhibitor or HO-1 knockout.

在腸缺血再灌流小鼠，電針足三里經膽鹼（α7nAChR）路徑於腸巨噬細胞誘導 miRNA124，降低 p-STAT3 與 IL-6、減少黏膜通透性；此效果被 α7nAChR 拮抗劑 MLA 阻斷。
In intestinal ischemia-reperfusion mice, EA at ST36 induced miRNA124 via the cholinergic (α7nAChR) pathway on intestinal macrophages, reducing p-STAT3 and IL-6 and lowering mucosal permeability; blocked by the α7nAChR antagonist MLA.

在膿毒症囓齒動物文獻中，刺激足三里作用於神經—內分泌—免疫網絡與血清外泌體，經交感與迷走神經系統（膽鹼型抗發炎路徑與迷走—內臟神經軸）產生抗發炎；低強度電針可活化與疾病無關的抗發炎路徑。
In rodent sepsis literature, ST36 stimulation acts on a neuro-endocrine-immune network and serum exosomes, producing anti-inflammatory effects via the sympathetic and vagus nervous systems (cholinergic anti-inflammatory pathway and vagal-splanchnic axis); low-intensity ST36 EA activates disease-independent anti-inflammatory pathways.

針灸可經自律神經核團（腦島、前額葉、ACC、杏仁核、下視丘、PAG、NTS、VLM、疑核）以傳出自律神經（交感＋副交感/迷走）緩解內臟功能失調與發炎；調節模式取決於穴位、參數與疾病模型。
Acupuncture, via autonomic nuclei (insula, PFC, ACC, amygdala, hypothalamus, PAG, NTS, VLM, nucleus ambiguus), alleviates visceral dysfunction and inflammation through efferent autonomic (sympathetic and parasympathetic/vagal) nerves; the modulation pattern depends on acupoint, parameters and disease model.

以體內微感測器即時量測，於手法（撚轉）針刺足三里時局部腺苷（ADO）瞬時釋放，且釋放變異量與刺激強度正相關。
An in vivo microsensor measured instantaneous local adenosine (ADO) release at ST36 during manual (twirling-rotating) acupuncture, with ADO release variability positively correlated to stimulus intensity.

假說性綜述提出機械敏感（MS）離子通道為介導針刺訊號的基本單元，以足三里為模型從局部起始、中樞整合到內臟效應；並提出 MS 通道普遍存在可解釋假針的療效。
A hypothesis review proposes mechanosensitive (MS) ion channels as fundamental units mediating acupuncture signaling, using ST36 as a model from local initiation to central integration to visceral effector responses; it also argues MS-channel ubiquity may explain sham-acupuncture efficacy.

健康受試者中，針刺足三里與解剖鄰近但適應症相異的 GB34 活化不同腦網絡；ST36 另強調視覺網絡，且其活化在空間上與 FDOPA、正腎上腺素轉運體（NET）與囊泡型乙醯膽鹼轉運體（VAChT）分布相關，支持穴位效果的特異性。
In healthy controls, acupuncture at ST36 and GB34 (anatomically adjacent, divergent indications) activated distinct brain networks; ST36 additionally emphasized the visual network and its activation spatially correlated with FDOPA, noradrenaline transporter (NET) and vesicular acetylcholine transporter (VAChT) distributions, supporting acupoint effect specificity.

針刺／電針足三里可改變藥物動力學：提高五味子木脂素與乙醯胺酚的吸收/血中濃度（AUC/Cmax 增加、Tmax 縮短）、改變組織分布、在較高劑量延遲乙醯胺酚清除、提高雷公藤甲素血中濃度/AUC；阿斯匹靈代謝不受影響。合併用藥時需留意。
