Effect of adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants and its action characteristics

The applicator therapy is a unique method to treat infant diarrhea in traditional Chinese medicines and widely applied in clinical practice. Currently,many researchers have proved the rationality of the therapy based on the traditional Chinese medicine mechanism and on the data from clinical practice,but its action mechanism is uncertain at present. In this study,with the assistance of pediatric practitioners,the automated ribosomal intergenic-spacer analysis( ARISA) was adopted to study the effect of the adjuvant therapy with Dingguier umbilical paste on intestinal flora of diarrhea infants,in which Dingguier umbilical paste served as the adjuvant therapy in oral traditional Chinese medicines and fecal samples of infants with different diarrhea symptoms were collected and used as the study materials. The results showed that the adjuvant therapy had a significant effect on the shift of intestinal flora,which was associated with the decrease in the similarity difference to the normal control group and the increase in the number of operational taxonomic units( OTUs) shared with the normal control group. Additionally,adjuvant therapy with Dingguier umbilical paste also showed long action duration and increased OTUs number. These results indicated that Dingguier umbilical paste has the effect in restoring the micro-ecosystem of unbalanced intestinal bacteria. Intestinal flora may be one of major targets for the applicator therapy for the infant diarrhea,but not for the single oral traditional Chinese medicine for infant diarrhea.
