Efficacy Observation of Electroacupuncture at the Three Groups of Stomach-Meridian Acupoints for Chronic Superficial Gastritis / 上海针灸杂志

ABSTRACT

Objective To observe the clinical efficacy of electroacupuncture (EA) at the three groups of Stomach- Meridian acupoints in treating chronic superficial gastritis (CSG) and its effect on serum gastrin level and electrogastrogram, for providing clinical evidence for the experimental result of the three groups of Stomach-Meridian acupoints.Method Sixty-six CSG patients were divided into a treatment group and a control group by using stratified random method, 33 cases in each group. The treatment group was intervened by EA at the three groups of Stomach-Meridian acupoints, while the control group was intervened by EA with ordinary acupoints selection. The intervention was given once a day, successive 6 sessions as a treatment course, for 4 courses in total. The CSG symptoms and syndrome score, serum gastrin content, average amplitude of electrogastrogram, mean waveform frequency, and the percentage of gastric dysrhythmias were observed before and after the intervention, and the clinical efficacies were compared.Result The total effective rate was 90.9％ in the treatment group, versus 87.9％ in the control group, and the between-group difference was statistically insignificant (P>0.05). The total scores dropped significantly in both groups after the treatment (P<0.05), and there was no significant difference in comparing the total score between the two groups after the treatment (P>0.05). The serum gastrin contents declined significantly in both groups after the intervention (P<0.05), and there was no significant between-group difference in comparing the serum gastrin content after the treatment (P>0.05); the average amplitude and mean waveform frequency of preprandial and postprandial electrogastrogram increased significantly in both groups after the treatment (P<0.05), and the percentage of gastric dysrhythmias dropped significantly (P<0.05); after the treatment, there were no significant between-group differences in comparing the average amplitude, mean waveform frequency and the percentage of gastric dysrhy- thmias of preprandial and postprandial electrogastrogram (P>0.05).Conclusion EA at the three groups of Stomach- Meridian acupoints can effectively improve the symptoms, down-regulate serum gastrin, help gastric motility, and restore gastric rhythm of CSG patients; its efficacy is equivalent to that of the classic acupoints group, i.e. Neiguan (PC6), Zhongwan (CV 12), and Zusanli (ST 36).
