肠道乳糖酶在小儿腹泻诊疗中的意义

Professor Lan Shu's experience of syndrome differentiation and prescription in treating infant diarrhea

This paper aims to clarify the theory of Chinese medicine for treating infant diarrhea by analyzing Professor Lan Shu's three representative cases of treating cold diarrhea, damp heat diarrhea, spleen diarrhea, and spleen and kidney deficiency diarrhea in infants with Huoxiang Zhengqi powder addition and subtraction, Gegen Qinlian decoction, Qiwei Baizhu powder addition and subtraction, and Fuzilizhong decoction. Due to the characteristics of the etiology and pathogenesis of infant diarrhea, Chinese medicine has a unique advantage in treating infant diarrhea. Based on the syndrome differentiation and according to the pathogenesis of cold and heat changes, adding or subtracting traditional Chinese medicine not only improves the clinical cure rate of infant diarrhea effectively, but also reduces the incidence of antibiotic-associated diarrhea.

蔗糖酶-异麦芽糖酶缺乏与腹泻的研究进展

蔗糖酶-异麦芽糖酶(sucrase-isomaltase, SI)是蔗糖酶在肠道内最主要的存在形式, 是最丰富的肠道二糖酶, 其包含了所有的蔗糖酶活性, 大部分的异麦芽糖酶活性及60%-80%的麦芽糖酶活性. 蔗糖酶-异麦芽糖酶缺乏症(sucrase-isomaltase deficiency, SID)是由于该二糖酶缺乏导致二糖吸收不良, 肠道正常生理功能受损, 机体营养不良, 生长发育落后, 甚至产生危及生命的胃肠道症状. 其最主要的临床表现是腹泻. 临床上通过调整肠道SI活性来治疗腹泻, 并将SI活性用于临床诊断. 本文主要阐述SID与腹泻的关系、研究进程以及诊疗手段, 促进SI在药理方面的研究.
