经皮耳穴迷走神经刺激对功能性消化不良大鼠的肠道连接蛋白的作用

Objective:Transcutaneous auricular vagus nerve stimulation(taVNS) can relieve the symptoms of functional dyspepsia(FD) and improve the quality of life of patients,however,the mechanism underlying this effect remains unclear.Therefore,this study aimed to investigate the effects of taVNS on the expression of intestinal mucosal ligandins.Methods:This study was conducted on 24 specific Spathogen-free Sprague-Dawley rats(12 males and12 females).The rat model of FD was established by tail-clip stimulation.After FD was established successfully,all rats were randomized to either the normal group(n=6),model group(n=6),taVNS group(n=6),or sham-taVNS group(n=6).After two weeks of the respective intervention,the score of their general conditions,3 h food intake,gastric emptying rate,and the histology of gastric antrum tissues were observed to evaluate modeling success,and then the effect of taVNS was evaluated.Western blotting was used to assess the expression of the tight junction ligandins-ZO-1 and occludin-and the adhesion ligandin-β-catenin-in the duodenum.The effect of taVNs on the expression of intestinal mucosal barrier ligandins-ZO-1,occludin,and β-catenin-in FD rats was preliminarily investigated.Results:When the model-induced period was finished,the manifestations of FD in the model group rats were mental exhaustion,reduced activities,decreased score of the general conditions,and decreased3 h food intake,compared to the normal group rats.In addition,minimal eosinophil infiltration,without any mucosal erosion or ulcer,was observed in the gastric antrum mucosa.At the end of the study,the mental state of the FD rats improved,and their activities and gastric emptying rate increased in the taVNS group rats.Compared to the normal rats,the duodenal mucosa had less expression of the tight junction ligandins ZO-1 and occludin,but β-catenin expression remained unchangedin the model rats.The expression of the tight junction ligandins ZO-1 and occludin were increased in the duodenal mucosa of model rats after the taVNS intervention.Conclusion:TaVNS can improve the gastric motility and mental state of rats with FD.It may play a therapeutic role by improving the expression of the tight junction ligandin ZO-1 and occludin in the duodenal mucosa,while also repairing the duodenal mucosal barrier.     

Treatment of tinnitus with electrical stimulation on acupoint in the distribution area of ear vagus nerve combining with sound masking: randomized controlled trial

ObjectiveTo observe the efficacy of treating tinnitus with electrical stimulation on acupoint in the distribution area of ear vagus nerve by combining with sound masking.MethodsSixty-three volunteers suffering from tinnitus were randomly divided into a treatment group (32 cases) and a control group (31 cases) according to envelope method. The treatment group was given the treatment with electrical stimulation on acupoint in the distribution area of ear vagus nerve by combining with sound masking while the control group was given the treatment by taking flunarizine hydrochloride capsules and oryzanol orally. The treatment for both groups lasted for eight weeks. The efficacy was evaluated before treatment, 4 weeks and 8 weeks following the treatment respectively according to “Tinnitus Handicap Inventory” and “Tinnitus Dysphoria Inventory”.ResultsIt was revealed from the Tinnitus Handicap Inventory that the differences were not statistically significant by comparing the two groups after treatment for 4 weeks (χ²=1.981, P=0.16); After 8 weeks of the treatment, patients with mild tinnitus and severe tinnitus were significantly improved in the treatment group compared with those before treatment (χ²=25.01, P<0.001) while the difference in the control group was not statistically significant before and after treatment (χ²=2.986, P=0.084), and the difference of the ratio of patients with mild tinnitus in the two groups was statistically significant (χ²=9.315, P=0.002). It was revealed from the Tinnitus Dysphoria Inventory that dysphoria of patients in the treatment group was more alleviated than that in the control group after treatment for 4 weeks (χ²=4.661, P=0.03); After 8 weeks of the treatment, the patients with mild dysphoria and severe dysphoria were significantly improved in the two groups (χ²=25.397, P<0.001 and χ²=7.828, P=0.005, respectively), and the efficacy in the treatment group was improved more significantly than that in the control group (χ²=5.857, P=0.016). It was shown from the comprehensive efficacy that after 8 weeks of treatment, the effective rates of the two groups were 90.63% (29/32) and 80.65% (25/31) respectively, and the difference between the two groups was not statistically significant (χ²=0.595, P=0.44). Conclusion Handicap and dysphoria of tinnitus can be improved significantly by treating with electrical stimulation on acupoint in the distribution area of ear vagus nerve and sound masking, and the efficacy was superior to that of western medicines.     

The Anticonvulsant Effect of Transcutaneous Auricular Vagus Nerve Stimulation is Associated with Balancing the Autonomic Dysfunction in Rats

Objective:The present study aims to investigate whether the anticonvulsant effect of transcutaneous auricular vagus nerve stimulation is associated with balancing the autonomic dysfunction in rats.Methods:Healthy adult male Sprague-Dawley rats were anesthetized with an intraperitoneal injection of 10% urethane.Seizures were evoked by intraperitoneal injection of pentylenetetrazol(PTZ,60 mg/kg).Femoral vein catheterization was performed for injection of sympathetic agonist and antagonists.Bipolar globe silver electrodes were utilized for epidural EEG recording.Three needles were inserted separately in subcutaneous muscles of left anterior limb,right anterior limb,and left hind limb to record ECG signals.ta-VNS was performed at auricular concha.Results:In comparison with preictal state,the mean heart rate(HR) increased slightly during epileptic seizures(P0.05).In comparison with ictal state,the mean HR decreased a little at postictal state(P0.05).When continuous epileptic seizures in EEG traces occurred(in ictal state),vein injection of propranolol hydrochloride(sympathetic antagonist) suppressed the epileptic seizures.When epileptic seizures occurred rarely(in postictal state),vein injection of adrenaline hydrochloride(sympathetic agonist) exacerbated the epileptic seizures.In comparison with prestimulation,the integral of EEG traces after ta-VNS decreased(P0.05),the mean HR decreased(P0.05),and the high power(HF) of HRV increased(P0.05) after ta-VNS.Conclusion:The results showed that autonomic dysfunction occurred in epileptic rats characterized by enhanced sympathetic nerve activity.Epileptic seizures in EEG traces decreased,HR decreased and HF increased after ta-VNS,which indicated that ta-VNS may suppress epileptic seizures via balancing the autonomic dysfunction.
