Abstract
Objective. By observing the sex difference of the gut microbiota in rats and the influence of Sophora flavescens (S. flavescens) on the gut microbiota in rats of different genders, it is hoped that it can provide reference materials for the rational use of S. flavescens in clinical practice. Method. Taking samples of the jejunum (containing intestinal contents) and feces of 8-week-old rats, and detecting the composition of gut microbiota of females and males by 16S rRNA sequencing technology; At the same time, 8-week-old rats were gavaged with different doses of S. flavescens decoction, and the duodenum, jejunum, ileum, and colon (including the intestinal contents) samples were collected at 1, 2, and 3 weeks, using polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technology and real-time fluorescent quantitative PCR (qRT-PCR) technology to observe the changes in the structure and the quantitative changes of 4 major intestinal dominant bacteria Enterococcus, Bacteriodes, Lactobacillus, and Clostridium in each intestinal segment, respectively. Result. (1) The gut microbiota of normal rats without administration also had obvious gender differences; (2) S. flavescens significantly affects the composition of gut microbiota, and in different intestinal segments, this effect was different between genders under different dosages and different continuous administration times. Conclusion. The effect of S. flavescens on the gut microbiota of rats had gender differences.
