Clinical Efficacy of Maxingshigantang Enema in Treating Infants with Pneumonia and Asthma and Intervention Mechanism of Lung-intestine Microenvironment / 中国实验方剂学杂志

ABSTRACT

ObjectiveTo observe the clinical efficacy of Maxingshigantang enema in the treatment of infant viral pneumonia by comparing related indicators， and comprehensively evaluate the effect of traditional Chinese medicine （TCM） enema on the intestinal microenvironment. MethodSixty infants with viral pneumonia were selected and randomly divided into 3 groups. The dosage of enema drugs in high- （0.117 g·mL-1） and low-concentration （0.07 g·mL-1） TCM enema groups was same （3.5 g per time）， and the control group received normal saline enema， once a day for 7 days. Finally， the curative effect， total symptom score， salivary secretory immunoglobulin A （sIgA）， human beta defensin 2 （hBD2） and fecal calprotectin （CALP） of each group were statistically analyzed by SPSS 21.0， and the clinical efficacy of TCM enema in treating children with pneumonia and asthma was comprehensively evaluated. ResultThe curative effect of high-concentration TCM enema group （total effective rate 100%， χ2=7.059） was equivalent to that of low-concentration TCM enema group （total effective rate 95%， χ2=4.329）， higher than that of control group （total effective rate 70%） （P<0.017）. After treatment， compared with control group and low-concentration TCM enema group， high-concentration TCM enema group had higher total symptom score of children （P<0.05， P<0.01）. The proportion of coccobacillus was reduced in three groups， with high- and low-concentration TCM enema groups lower than control group （P<0.05）. The salivary sIgA concentration was increased in three groups （P<0.05）， with high-concentration TCM enema group higher than the other groups （P<0.01）. The hBD2 concentration was decreased in three groups， with high- and low-concentration TCM enema groups lower than control group （P<0.05）. The three groups reduced the fecal CALP concentration， and high-concentration TCM enema group had the highest reduction， followed by low-concentration TCM enema group （P<0.01）. ConclusionTCM enema outweighs western medicine in improving clinical symptoms， intestinal flora， and mucosal immune function， and reducing inflammation in children， and the high-concentration TCM enema group has better curative effect. Therefore， with easiness to operate， high compliance， and significant therapeutic effect， TCM enema is worthy of clinical promotion.
