Abstract
Background The use of transcranial magnetic stimulation combined with electromyography for the functional evaluation of the cerebral cortex in both clinical and non-clinical populations is becoming increasingly common. Numerous studies have shown that electro-acupuncture (EA) can regulate cerebral cortical excitability. However, the effect of EA on the lateralization of the human swallowing motor cortex excitability is not yet fully understood. Objective The aim of this study was to assess whether lateralization is present in the swallowing motor cortex of healthy subjects, and to investigate the impact of EA at Lianquan (CV23) and Fengfu (GV16) on lateralization. Methods Forty subjects were randomized 1:1 into the EA group and the sham-EA group. The bilateral swallowing motor cortices was located by a neuroimaging navigation system. Then, the resting motor threshold (RMT) and motor evoked potential (MEP) of the mylohyoid of healthy subjects were recorded while applying combined transcranial magnetic stimulation and electromyography before and after EA or sham-EA. Results First, the RMT and MEP latency of the contralateral mylohyoid innervated by the right swallowing cortex (71.50 ± 1.67%, 8.30 ± 0.06 ms) were lower than those innervated by the left (79.38 ± 1.27%, 8.40 ± 0.06 ms). Second, EA at CV23 and GV16 reduced the bilateral RMT and enhanced the bilateral MEP latency and amplitude (P = 0.005, P < 0.001; P = 0.002, P = 0.001; P = 0.002, P = 0.009), while sham-EA did not (P > 0.05). Third, EA had an effect on the RMT and MEP latency in terms of lateralization changes, but this was not significant (P = 0.067, P = 0.156). Conclusion The right swallowing motor cortex of healthy subjects is more excitable than that of the left at resting state. Thus, we found that lateralization is present in the swallowing motor cortex of healthy people, which might indicate a hemispheric dominance of swallowing predominates in the right swallowing motor cortex. In addition, EA at CV23 and GV16 can instantly promote the excitability of the bilateral swallowing motor cortices. But there was no significant difference in EA stimulation in terms of lateralization.

Abstract
BACKGROUND The present study aimed to explore the effectiveness of electro-acupuncture (EA) in combination with a local anesthetic used in Western medicine in preventing the side effects of gastroscopy. METHODS A sample group of 150 patients were divided into three groups based on treatment methods: an EA group, a dyclonine hydrochloride mucilage group, and a combined treatment group. In the EA group, EA stimulation was given at the Hegu, Neiguan, and Zusanli acupoints; in the dyclonine hydrochloride mucilage group, patients took 10 mL of dyclonine hydrochloride mucilage orally; in the combined treatment group, prevention of side effects was attempted by administration of both acupuncture and oral local anesthetic. The incidences of nausea, emesis, salivation, cough, restlessness, and breath holding during gastroscopy were observed and recorded for the three groups. Mean arterial pressure, heart rate, and oxygen saturation were recorded before the examination, and changes in these measures were recorded as the gastroscope passed through the pylorus and after the examination. The visual analogue scale (VAS) values of nausea and emesis, the rate of successful first-pass intubation, and the time of gastroscopy were also recorded. Statistical analysis was performed using R-3.5.3 software. RESULTS Incidences of side effects (e.g., nausea, emesis, salivation, restlessness, and breath holding) during the examination were lower in the combined treatment group than in the EA group and the dyclonine hydrochloride mucilage group (P<0.05 and P<0.01, respectively). Furthermore, the changes in heart rate and oxygen saturation when the gastroscope passed through the pylorus and after the examination were better in the combined treatment group than in the EA group and dyclonine hydrochloride mucilage group (P<0.01). The VAS values of nausea and emesis, the first-pass success rate, and examination duration were also better for the combined treatment group than for the other two groups (P<0.05 and P<0.01). CONCLUSIONS EA combined with local anesthesia with dyclonine hydrochloride mucilage can alleviate side effects during gastroscopy, reduce patient pain, and improve the efficiency of the procedure.
