消化道疾病是一种常见病、多发病

至今对胃肠道疾病诊断的检查方法有X线钡餐造影、纤维内窥镜等。长期来中医针灸临床常取足三里穴为治疗肠胃道疾病的主穴。而且国内已有不少工作证实足三里穴对胃肠道生理功能确有一定的影响

但缺乏一种无痛苦的客观记录。自Alyarez等从人的腹壁体表记录到胃电后

许多学者都企图应用胃电作为胃机能活动的指标研究胃的生理病理规律

希望胃电能作为胃疾患临床诊断和Using a untraumatic method of the surface electrode unipolar leads

the electrogastrogram (EGG) and tbe effect of needling reaction appeared on EGG were recorded in 40 normal subjects and 104 patients suffering from gastroduodenal disease. 1. In 40 normal subjects the average values of frequency and amplitu- de of EGG were 3.26±0.06 c/min. and 181.6±16.91μV respectively before dinner the frequency and amplitude of EGG were 3.21±0.06 c/min. and 236.2±17.30μV

respertively after dinner. 2. Before dinner the average frequency and amplitude of EGG were 3.29±0.1 c/min

and 229.4±28.5μV in 8 cases with gastric ulcer

3.26± 0.33 c/min

and 261.9±66.6μV in 36 cases with duodenal ulcer

3.14±0.14 c/min and 159.7±25.5μV in 10 cases with duodenitis

3.40±0.05c/min.and 50.14±8.72μV in 41 cases with surficial gastritis

3.33±0.18 c/min

and 47.58±4.12μV in 7 cases with atrophic gastritis and 3.16±9.71 c/min. and 43.1±16.7μV in 2 cases with gastric cancer. After dinner the mean frequency and amplitude of EGG were as bellow: 33.3±0.22 c/min and 351.5±51.6μV in the gastric ulcer cases

3.21±0.06 c/min.and 327.8±49.4μV. in the duodenal ulcer cases

2.96±0.5 c/min and 218.3±50.2 μV the duodenitis eases

3.30±0.05 c/min

and 119.1±14.3μV

in the surficial ga- stritis cases

3.52±0.16 c/min

and 54.74±19.14μV in the atrophic gastritis cases

3.50±0.84 c/min and 53.4±2.98μV in tha gastric cancer cases. The above results show that after dinner the amplitude of EGG incr- eased significantly

but the frequency did not change significantly. 3. In the 12 patients with gastroduodenal disease before acupunctur- ing Zusanli acupoint

the mean amplitude of EGG was 276.3±55.7 μV. When neediling reaction appcared

the mean amplitude of EGG increased to 459.7±90.67 μV. When the needie manipulation was stopped the amplitude of EGG decreased to 355±92.67μV

but the frequency of EGG did not have significat change. 4. The results in observing the relation of TCM differentiation of syndromes with EGG were as bellow: Among 89 patients with epigastric pain

50 cases were with Xu type of the spleen and stomach miningled wi- th cold type

5 cases with syndromes of Yin Xa

6 cases with Xu of the spleen and stomach with cold accompanied attach on stomach by liver Qi type

the amplitude of EGG was lower than that of the normal subjects

but in 21 cases with simple attach on stomach by liver Qi type and in 5 cases with accumulation of heat in the liver and stomach the mean ampli- tude were higher that of the normal subjects.
