Regulatory Effect of Quyu Huatan Tongmai Prescription on Intestinal Microflora in Golden Hamster with Hyperlipidemia / 中国实验方剂学杂志

ABSTRACT

ObjectiveTo explore the regulatory effect of Quyu Huatan Tongmai prescription on intestinal mircoflora of hyperlipidemia golden hamster and scientific evidence for the compatibility. MethodSyrian golden hamsters were randomized into normal， model， prescription， stasis-dispelling （Quyu）， phlegm-dissolving （Huatan）， and detoxification （Jiedu） groups， with 8 in each group. Hyperlipidemia in golden hamsters was induced by high-fat diet （4 weeks）. Then hamsters in the Quyu group （1.11 g·kg-1）， Huatan group （0.39 g·kg-1）， Jiedu group （0.07 g·kg-1）， and prescription group （1.42 g·kg-1） were given （ig） corresponding drugs and those in the normal group and the model group received （ig） distilled water of equivalent volume， once a day for 6 weeks. Serum lipids were determined， and hematoxylin-eosin （HE） staining was used to observe the pathological morphology of the liver. Feces were collected for 16S rRNA gene high-throughput sequencing of intestinal flora. ResultCompared with normal group， the model group demonstrated increase in body weight （P<0.05， P<0.01） and blood lipids （P<0.01）， decrease in intestinal flora diversity （P<0.05， P<0.01）， and variation of the relative abundance of intestinal flora at phylum， family， and genus levels （P<0.05， P<0.01）. Compared with the model group， Quyu Huatan Tongmai prescription controlled the body weight change， reduced the serum triglyceride （TG）， total cholesterol （TC）， and low density lipoprotein cholesterol/high density lipoprotein cholesterol ratio （LDL-C/HDL-C） （P<0.05， P<0.01）， improved the structure of intestinal flora， decreased the ratio of Firmicutes to Bacteroides （P<0.01）， raised the abundance of Bacteroidaceae， Porphyromonadaceae， Rikenellaceae， and Pasteurella （P<0.05， P<0.01）， and lowered the relative abundance of Coriobacterium （P<0.05） in hyperlipidemia golden hamsters. All the split prescriptions improved blood lipids and intestinal flora of the hamsters and particularly， the lipids-lowering effect of the Jiedu group and the regulation of flora in the Huatan group were closer to those of the prescription group. ConclusionQuyu Huatan Tongmai prescription and the split prescriptions all alleviated the hyperlipidemia of golden hamsters to different degrees possibly by regulating intestinal flora structure and improving intestinal microecology. The effect of the prescription group was most significant， and coming in second was the Huatan group. This study also provides scientific evidence for the effect of Quyu Huatan Tongmai prescription.
