电针“胃经三段组穴”治疗慢性浅表性胃炎疗效观察

Efficacy Observation of Electroacupuncture at the Three Groups of Stomach-Meridian Acupoints for Chronic Superficial Gastritis

目的观察电针"胃经三段组穴"治疗慢性浅表性胃炎的临床疗效,对患者血清胃泌素水平及胃电图的影响,为"胃经三段组穴"这一实验研究成果提供临床依据。方法将66例慢性浅表性胃炎患者采用分层随机法分为治疗组和对照组,每组33例;治疗组采用"胃经三段组穴"电针,对照组采用常规穴位电针。每日1次,连续治疗6 d为1个疗程,共治疗4个疗程。观测两组患者治疗前后慢性浅表性胃炎证候积分、血清胃泌素含量、胃电图的平均幅值、波形平均频率及胃电节律紊乱百分比的变化情况,并比较临床疗效。结果治疗组总有效率为90.9%,对照组为87.9%,两组比较差异无统计学意义(P>0.05)。两组治疗后总积分均较同组治疗前明显下降(P<0.05),两组治疗后总积分比较,差异无统计学意义(P>0.05)。两组患者治疗后血清胃泌素含量均较同组治疗前明显下降(P<0.05),两组治疗后血清胃泌素含量比较差异无统计学意义(P>0.05);两组患者治疗后餐前和餐后胃电平均幅值、平均频率均较同组治疗前显著提高(P<0.05),胃电节律紊乱百分比与同组治疗前比较明显降低(P<0.05),两组治疗后餐前和餐后胃电平均幅值、平均频率及胃电节律紊乱百分比较差异无统计学意义(P>0.05)。结论电针"胃经三段组穴"能有效改善慢性浅表性胃炎患者临床症状,降低血清胃泌素含量,改善胃运动功能,并使患者的胃电节律趋于正常化,且疗效与经典的"内关、中脘、足三里"腧穴组相当。

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 dysrhythmias of preprandial and postprandial electrogastrogram （P〉 0.05）. Conclusion EA at the three groups of StomachMeridian 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）.
