In 40 normal subjects, the average of amplitudeand frequency of EGG were 150-180 μV and 3 cycles/min respectively before eating, but after eatingthe amplitude was about 236.2 μV and the frequency was about 3.21 cycles/rain. EGG diagnosis of100 patients with gastralgia was conformed to the gastroscopic diagnosis, with the rate 84%. The re-lations between effects of acupuncture and Qigong, the PSC and the differentiation of syndromes ofTCM and EGG were explored.展开更多

In this paper, the electroacupuncture (EA) treatments were performed on subjects with slight gastric disorders and the EEGs were monitored in the meanwhile. The EEGs features of baseline, during and after EA treatments were analyzed. The results show that the EA treatments do enhance the regularity of EEGs. And a highly possible pattern for EA to attain the enhancement is to regulate the pacemaker quantity and propagation of slow waves rather than regulating the amplitude of slow waves.展开更多

The authors analyzed the EGGs by using the maximum Lyapunov exponent （MLE）, which is one of the indices of the chaotic characteristics of time series. Significant differences were observed between the MLEs estimated from the, EGGs of the young and elderly individuals for most of the temporal intervals. The authors＇ data indicate that the EGGs of elderly gastrectomized subjects might be distinguished from the EGGs of healthy elderly individuals on the basis of the MLE distribution.展开更多

Methods: Fifty Wistar rats were randomly divided into 5 groups: a control group, a Zusanli group, a non-point group, a Taichong group and a Neiguan group. Rats were anesthetized after 18 h of fasting, and a rat model of nociceptive blood pressure elevation and abnormal electrogastrogram (EGG) and gastric tension (GT) was prepared by gasbag-induced CRD. EA was given bilaterally, and its effects on gastric blood flow (GBF) of the arcus vasculosi of the greater omentum, blood pressure, EGG fast wave properties, and gastric smooth muscle tension (GT) were quantified. Results: CRD induced an increase in blood pressure that was significantly inhibited by EA at all points (all P<0.05), and the inhibitory effects were greater in the Zusanli and Neiguan groups compared to the non-point group (both P<0.05). CRD also caused reductions in GT and GBF, and in the amplitude, frequency and duration of EGG waves (all P<0.05). These effects were also reversed by EA. The effects of EA on EGG wave amplitude, GT, and GBF were superior in the Zusanli group compared to the Taichong group, Neiguan group, and the non-point group. Conclusion: EA significantly counteracted CRD-induced changes in blood pressure, GBF, EGG, and GT. The effects of stimulation at Zusanli (ST 36) were significantly greater compared to other points, indicating relative specificity of this acupoint.展开更多

Methods： A total of 65 cases were randomized into a Zusanli （ST 36） group （n=33） and a Yanglingquan （GB 34） group （n=32） by random serial number, to receive moxibustion therapy to the corresponding point respectively. The 8-lead EGG was used before and after treatment to collect EGG parameter of the gastric body, antrum of stomach, lesser curvature and greater curvature, including the dominant frequency, slow wave percentage, average frequency, response area and motility index. Results： After treatment, the dominant frequency and slow wave percentage were improved in nearly the whole stomach area in Zusanli （ST 36） group, showing statistical significances （both P〈0.05）; the slow wave percentage and average frequency were improved in stomach body and antrum of stomach in Yanglingquan （GB 34） group, showing statistical significances （both P〈0.05）; moxibustion at Zusanli （ST 36） had a significantly higher influence on EGG than Yanglingquan （GB 34）, in which the lifting of slow wave percentage was significantly higher than Yanglingquan （GB 34） group （P〈0.05）. Conclusion： Moxibustion at Zusanli （ST 36） and Yanglingquan （GB 34） has the effect of adjusting abnormal EGG pattern in FD patients. Compared with Yanglingquan （GB 34）, Zusanli （ST 36） has a superior effect in improving EGG in stomach area.展开更多
