Aim of the study
The purpose of the present study is to research on mechanism of hawthorn decoction coupled with odor of charred hawthorn on digestive in rats with HC-DID. Materials and
Conclusion
The above study showed that hawthorn decoction coupled with the odor of charred hawthorn effectively alleviate HC-DID in rats by regulating the "Brain-Gut" axis and gut flora. Odor treatment of hawthorn could be a potential therapeutic approach for HC-DID.
Methods
The SPF Kunming (KM) mice and Sprague Dawley (SD) rats were randomly divided into 7 groups: control group, model group, cisapride group, hawthorn group (HT), charred hawthorn group (CHT), odor of charred hawthorn (OCHT), CHT + OCHT group. The rats were modeled as HC-DID, whose treatment by intragastric administration and odor administration. Obvious symptoms of HC-DID were observed. Gastrointestinal motility were detected. Histopathology was performed in hypothalamus and gastrointestinal tract. Related brain-gut peptides were assayed in serum, hypothalamus and gastrointestinal tract. Illumina Miseq platform was used for 16S rDNA high-throughput sequencing to detect the intestinal flora structure of the caecum of rats.
Results
Traditional Chinese medicine decoction of hawthorn (HT and CHT) regulated the body weight, food intake, gastrointestinal motility and abnormal secretion of brain-gut peptides in rats with HC-DID, and the odor of charred hawthorn also had good curative effect for it. Moreover, the intestinal dysbiosis was induced by high-calorie diet in rats with dyspepsia, and hawthorn decoction could ease this trend.
