  "abstract": "Background: Painful diabetic peripheral neuropathy (PDPN) is a complication of diabetes characterized by neuropathic pain, with metabolic dysfunction and neuroinflammation implicated in its pathophysiology. Although electroacupuncture (EA) may alleviate neuropathic pain, its broader effects in PDPN remain unclear.\n\nMethods: PDPN was induced by high-fat feeding and repeated streptozotocin injections. Two independent experiments (n = 10 mice/group) included Control, PDPN, and EA groups; Experiment 2 additionally included EA+capsaicin and EA+vehicle groups. Capsaicin was given after each of the final four EA treatments to examine transient receptor potential vanilloid 1 (TRPV1)-related responses. After model confirmation, PDPN mice were re-randomized into groups and randomly allocated within groups for subsequent analyses. EA was applied at ST36, BL13, BL20, BL23, and SP6. Pain behavior, nerve conduction, histopathology, and inflammatory and metabolic markers were assessed. Additionally, sciatic nerve transcriptomic and untargeted metabolomic data were integrated by pathway-based network analysis.\n\nResults: EA improved pain-related behavior and sciatic nerve conduction velocity. On day 75, thermal withdrawal latency (TWL) increased by 5.59 s (95% confidence interval [CI], 4.35–6.83; Cohen’s d = 4.23) and mechanical withdrawal threshold (MWT) by 0.95 g (95% CI, 0.79–1.12; Cohen’s d = 5.39) versus PDPN mice. EA also attenuated sciatic nerve pathological and inflammatory changes in PDPN mice, lowered dorsal root ganglion TRPV1 protein levels by 54.2% (n = 3/group), reduced spinal glial-associated inflammatory immunoreactivity, and improved relevant metabolic indicators. Capsaicin partially attenuated several of these EA-associated responses, providing supportive but not definitive evidence for TRPV1 involvement. Multi-omics analyses revealed exploratory associations involving lipid, energy, and redox metabolism.\n\nConclusion: EA reduced pain hypersensitivity and improved nerve function alongside neuroinflammatory and metabolic changes in PDPN mice. And multi-omics findings generate hypotheses about metabolic processes associated with EA treatment, but their causal contributions to analgesia require further investigation.",
