BACKGROUND:Visceral hypersensitivity (VH) is acknowledged as a critical pathogenic mechanism underlying functional gastrointestinal disorders (FGIDs), which is influenced by dysregulation of the gut-brain axis. Transauricular vagus nerve stimulation (taVNS) is a clinically used intervention for the relief of visceral pain; however, its underlying neural mechanisms remain poorly understood. Drawing on the pathogenesis of VH and our team's previous research, we hypothesized that taVNS mitigates VH through the nesfatin-1/corticotropin-releasing factor (CRF) pathway. This study aims to elucidate the potential central regulatory mechanisms that contribute to the analgesic effects of taVNS. METHODS:A validated VH model was established in Sprague-Dawley (SD) rats through maternal separation (MS) combined with acetic acid enema. The VH rats underwent taVNS at frequencies of 2 Hz, 10 Hz, and 15 Hz, whereas the sham group received 2 Hz electrical stimulation at the earlobe. The visceral pain threshold was evaluated using the abdominal withdrawal reflex (AWR) scoring and electromyographic activity of the external oblique muscle. Additionally, Western blot analysis was conducted to assess the expression levels of nesfatin-1, CRF, and its receptors 1 and 2 (CRF1/2R) in the hypothalamus. KEY RESULTS:The analyses of AWR and electromyogram (EMG) responses indicated that (a) the area under the curve (AUC) of the EMG response to colorectal distension (CRD) at four distension pressures (20, 40, 60, and 80 mmHg) was significantly elevated in the VH group. (b) The AUC was significantly reduced in the 2 Hz taVNS group across all four distension pressures. (c) The 10 Hz taVNS group exhibited a significant decrease in the AUC at 20 mmHg and 40 mmHg. Furthermore, the results of Western blot analysis demonstrated that (a) 2 Hz taVNS significantly lowered the expressions of nesfatin-1, CRF, and CRF1R, aligning with the findings in the sham group. (b) Both 10 Hz and 15 Hz taVNS significantly decreased CRF expression, whereas nesfatin-1 and CRF1R expression remained unchanged. (c) There was no significant downregulation of CRF2R expression among the intervention groups. CONCLUSION:This study demonstrated that taVNS alleviates VH, potentially via the nesfatin-1/CRF/CRF1R signaling pathway in the rat hypothalamus. Furthermore, the analgesic effect was frequency-dependent, with 2 Hz taVNS providing a more effective reduction in visceral pain.
Background/Aims Diabetes mellitus is a prevalent chronic condition globally. A frequent complication is gastric motility disorder, which substantially impacts patients' quality of life and overall well-being. The SMC-ICC-PDGFRα+ (SIP) syncytium plays an important role in the coordination of gastrointestinal (GI) motility. Auricular vagus nerve stimulation (aVNS) has demonstrated promising therapeutic efficacy against diabetic motility disorders, yet the underlying mechanism has not been well understood. The present study aims to evaluate whether low-frequency aVNS attenuates gastric dysmotility in diabetic rats through regulation of the SIP syncytium and its signaling pathways. Materials and Methods Male Sprague-Dawley rats were employed to induce the diabetic gastric motility disorder (DGMD) model using streptozotocin (STZ). The DGMD rats underwent treatment with aVNS, a combination of aVNS and body electroacupuncture (aVNS-EA), and sham aVNS. Gastric motility was evaluated by solid gastric emptying rate (SGER). Gastric antrum pathology was assessed via H&E staining, SIP syncytium function was evaluated by immunofluorescence, and serum nitric oxide (NO) levels with a Griess kit. Results Low-frequency aVNS significantly enhanced SGER and up-regulated the expression of ICCs and PDGFRα+ cells in the antrum, the smooth muscle marker α-SMA was increased at the immunofluorescence and mRNA levels but not significantly at the protein level. aVNS-EA exhibited similar effects, whereas sham aVNS showed no significant change. aVNS also up-regulated nNOS, increased NO release, and activated the sGC–cGMP–PKG1 pathway. Treatment with ODQ (1H-[1,2,4]oxadiazolo[4,3-a]quinoxalin-1-one), the sGC inhibitor, reversed the aVNS-induced improvements in SGER and SIP syncytium integrity. Conclusion In contrast, aVNS-EA benefits were only partially inhibited by ODQ. These results suggest that low-frequency aVNS improves gastric motility and SIP syncytium function in diabetic rats by activating the NO/sGC/cGMP/PKG1 pathway, and the combination of aVNS and body electroacupuncture yields additional beneficial effects. Clinical trial registration Not applicable.
Objective: Functional dyspepsia (FD), which has a complicated pathophysiologic process, is a common functional gastrointestinal disease. Gastric hypersensitivity is the key pathophysiological factor in patients with FD with chronic visceral pain. Auricular vagal nerve stimulation (AVNS) has the therapeutic effect of reducing gastric hypersensitivity by regulating the activity of the vagus nerve. However, the potential molecular mechanism is still unclear. Therefore, we investigated the effects of AVNS on the brain-gut axis through the central nerve growth factor (NGF)/ tropomyosin receptor kinase A (TrkA)/phospholipase C-gamma (PLC-gamma) signaling pathway in FD model rats with gastric hypersensitivity. Materials and Methods: We established the FD model rats with gastric hypersensitivity by means of colon administration of trinitrobenzenesulfonic acid on ten-day-old rat pups, whereas the control rats were given normal saline. AVNS, sham AVNS, K252a (an inhibitor of TrkA, intraperitoneally), and K252a + AVNS were performed on eight-week-old model rats for five consecutive days. The therapeutic effect of AVNS on gastric hypersensitivity was determined by the measurement of abdominal withdrawal reflex response to gastric distention. NGF in gastric fundus and NGF, TrkA, PLC-gamma, and transient receptor potential vanilloid 1 (TRPV1) in the nucleus tractus solitaries (NTS) were detected separately by polymerase chain reaction, Western blot, and immunofluorescence tests. Results: It was found that a high level of NGF in gastric fundus and an upregulation of the NGF/TrkA/PLC-gamma signaling pathway in NTS were manifested in model rats. Meanwhile, both AVNS treatment and the administration of K252a not only decreased NGF messenger ribonucleic acid (mRNA) and protein expressions in gastric fundus but also reduced the mRNA expressions of NGF, TrkA, PLC-gamma, and TRPV1 and inhibited the protein levels and hyperactive phosphorylation of TrkA/PLC-gamma in NTS. In addition, the expressions of NGF and TrkA proteins in NTS were decreased significantly after the immunofluorescence assay. The K252a + AVNS treatment exerted a more sensitive effect on regulating the molecular expressions of the signal pathway than did the K252a treatment. Conclusion: AVNS can regulate the brain-gut axis effectively through the central NGF/TrkA/PLC-gamma signaling pathway in the NTS, which suggests a potential molecular mechanism of AVNS in ameliorating visceral hypersensitivity in FD model rats.
Background and objectives:Gastrointestinal dysmotility commonly follows thermal injuries, such as burns. This study aimed to investigate the effects and mechanisms of electroacupuncture (EA) on burn-induced gastric dysmotility in rats. Methods:Sprague-Dawley rats were divided into sham and thermal injury groups subjected to a 60% scald burn. Antagonists, including β-blockade (propranolol), α-blockade (phentolamine), or a selective cyclooxygenase (COX)-2 inhibitor (nimsulide), were administered to verify the pathways involved. Six hours after the burn, the animals were evaluated for gastric emptying and heart rate variability. Blood and gastric tissues were collected for assays of cytokines, hormones, and COX-2 levels. EA was performed at bilateral ST36 (Zusanli) acupoints for 45 m. Results:Burn injury delayed gastric emptying by 61% (P < 0.01), which was normalized by nimsulide or propranolol but not by phentolamine. EA improved gastric emptying by 87% (P = 0.03) in burned rats. Heart rate variability and plasma hormone (noradrenaline and pancreatic polypeptide) analyses indicated sympathetic hyperactivity in burned rats; EA improved burn-induced sympathovagal imbalance by enhancing vagal activity. Protein and mRNA expressions of COX-2 in the gastric fundus and antrum increased with burn but were normalized by propranolol. EA reduced the burn-induced increase in COX-2 expression in the gastric fundus but not in the antrum. EA also decreased burn-induced elevations in plasma interleukin (IL)-6 and IL-10. Negative correlations were found between gastric emptying and plasma IL-6 levels, as well as between gastric emptying and COX-2 mRNA levels. Conclusions:These findings suggest that burn-induced gastric dysmotility is mediated via autonomic-COX-2 pathways. EA at acupoint ST36 improves burn-induced delays in gastric emptying by down-regulating COX-2 and pro-inflammatory cytokines through the autonomic nervous pathway.

OBJECTIVE:To observe the effect of electroacupuncture (EA) at "Ashi" acupoint and "Kunlun" (BL60) on elastic modulus, histopathological changes and expression of myogenic regulatory factors in gastrocnemius(GM) contusion rats, so as to explore the therapeutic effect of local acupoint selection and acupoint selection along channel. METHODS:Male SD rats were randomly divided into blank control (n=5), model (n=15), Ashi-point (n=15) and BL60 (n=15) groups. The acute GM contusion model was established by striking (free falling) the GM with a homemade hitter. EA (0.5 to 1.0 mA, 2 Hz/10 Hz) was applied to Ashi-point (local focus) and BL60 for 30 min 24 h after muscle injury. The elasticity maximum (Emax) of gastrocnemius muscle was measured by using an ultrasonic device. Histopathological changes were observed after H.E. stain, and the number of Myogenic differentiation(MyoD)- and Myogenin (MyoG)-positive cells was detected by using immunohistochemistry. RESULTS:After mdeling, the Emax value of GM was significantly increased from the 3rd h to 7th day in comparison with pre- injury of muscle (P<0.05), and was markedly increased on the 3rd day and obviously lower on day 7 in the Ashi-point group than in the model group (P<0.05). The numbers of MyoD- and MyoG-positive cells of GM were significantly increased on day 7 in the model group than in the blank control group (P<0.05), and both further increased in Ashi-point on day 3 and 5, and MyoG-positive cells further increased in BL60 group on day 5 and in Ashi-point group on day 7 relevant to the model group(P<0.05). The therapeutic effect of EA-Ashi-point was apparently superior to that of BL60 in up-regulating Emax on day 3 and in up-regulating the number of MyoD-positive cells on day 3 and 5 (P<0.05). H.E. stain showed disordered arrangement of muscle fibers, infiltration of inflammatory cells, increase of intercellular space, and edema on day 3 after modeling (which was milder in the Ashi-point group); and gradual fusion and thickening of new born muscle fibers with obvious connective tissue hyperplasia converged to the lesioned region on day 7 in the model group (convergence of new born muscle cells to the lesion region in both EA groups, and more complete tissues in the Ashi-point group). CONCLUSION:EA of Ashi-point and BL60 can up-regulate the expression of myogenic regulatory factors MyoD and MyoG of GM tissue in GM contusion rats, which may contribute to its function in promoting recovery of muscle elasticity. The role of EA-Ashi-point is superior to that of EA-BL60.

To assess the effects of electro-acupuncture (EA) on glycemic control, myocardial inflammation, and the progression of diabetic cardiomyopathy in mice with type 2 diabetes. Db/Db mice received EA at PC6+ST36 (DM-Acu), non-acupoint simulation (DM-Sham), or no treatment (DM). EA was applied for 30 min per day, 5 days a week for 4 weeks. Heart function was assessed by echocardiography. Myocardium was assessed by RT-PCR, immunoblotting, and histology. Serum TNF-α, IL-1α, IL-1β, IL-6, and IL-8 were measured. DM-Acu, but not DM-Sham, reduced fasting blood glucose without affecting body weight. DM decreased systolic function. DM-Acu, but not DM-Sham, attenuated the decrease in systolic function. Heart weight was significantly smaller in the DM-Acu than in the DM and DM-Sham groups. Percent fibrosis and apoptosis were reduced in the DM-Acu, but not the DM-Sham, group. Serum levels of IL-1α, IL-1β, IL-6, IL-8, ICAM-1, MCP-1, and TNF-α were significantly lower in the DM-Acu than in the DM or DM-Sham groups. Protein levels of P-Akt and P-AMPK and mRNA levels of phosphoinositide-3-kinase regulatory subunit 6 (PIK3r6) were significantly higher in the DM-Acu group. Myocardial mRNA and protein levels of insulin-like growth factor 1 receptor (IGF1R) were significantly lower in the DM and DM-Sham groups compared with the DM-Acu group. EA reduced serum glucose; prevented DM-induced hypertrophy and deterioration of systolic function, inflammation, and fibrosis; and restored IGF1R, P-Akt, and P-AMPK levels in mice with type 2 diabetes mellitus.
