163例不同证候大便异常患者结肠电频谱变化分析

Analysis on Changes of Electric Frequency Spectrum of the Colon in 163 Cases of Abnormal Defecation with Different Syndromes

对163例消化道等疾病患者中医辨证及临床症状统计发现,肝气乘脾、脾虚肝郁、脾虚便溏、气虚便秘、气滞便秘等证有大便异常或大便异常倾向的患者占60％～100％。体表结肠电检测及频谱分析发现,肝气乘脾患者结肠低频、高频段及收缩性复合肌电过度活跃;脾虚便溏患者升、降结肠高频段及收缩性复合肌电过度活跃,乙状结肠高频段电活动减弱;气虚便秘及气滞便秘患者结肠的低频、高频段及收缩性复合肌电都明显减弱,但气滞便秘患者餐后结肠高频段及收缩性复合肌电活动明显强于气虚便秘患者,可予分辨。结肠电频谱可间接反映不同证候的结肠动力改变,并能部分解释其大便改变及相关症状的发生机制。

Statistical analysis of TCM syndrome differentiation and clinical symptoms were made in 163 cases of diseases of digestive tract. It was found that the patients of abnormal defection or tendecy of abnormal defecation with the hyperactive liver - Qi attacking the spleen, stagnation of liver -Qi due to hypofunction of the spleen, loose stool due to deficiency of the spleen, constipation due to Qi-deficiency, constipation due to Qi - staganation syndromes accounted for 60%- 100%. Elecrtic examination of colon on the body surface and analysis of frequancy spectrum found that hyperelectroactivity of low - frequency and high - frequency segment of colon and contractive complex myoelectric hyperactivity in the patients of the hyperactive liver - Qi attacking the spleen; hyperelectroactivity of high - frequency segment of the ascending and descending colon and contractive complex myoelectric hyperactivity and decrease of electric activity of high - frequency segment of the sigmoid colon in the patients of loose stool due to hypofunction of the spleen: obvious decrease of electric activiy of low - frequency and high -frequency of the colon and contractive complex myoelectric hyperactivity in the patients of constipation due to deficiency of Qi or Qi - stagnation, but electric activity of the high -frequency segment of the colon and contractive complex myoelectric activity after meal in the patients of constipation due to Qi -stagnation was stronger than that in the patients of constipation due to Qi - deficiency. Electric frequency spectrum of colon can indirectly reflect changes of colon dynamics of different syndromes, and it can partially expain the changes of stool and the mechanism of relative symptoms.
