RESUMO

Objective:To explore the effect of Chaihu Longgu Mulitang on intestinal microflora diversity of schizophrenic model rats, and further reveal its therapeutic characteristics and mechanisms based on the 16S rRNA technique. Method:Except the normal group, male SD rats were intraperitoneally injected dizocilpine maleate with daily dose of 0.1 mg·kg-1.After the success of the model, Chaihu Longgu Mulitang high, middle and low dose groups were converted into the human clinical upper limit daily, and the experimental rats were given Chaihu Longgu Mulitang with doses of 11.2, 5.6, 2.8 g·kg-1, respectively. And the positive drug group was treated with 0.4 mg·kg-1 of risperidone tablets.The normal group and model group was treated with water.The rats were continuous administrated 14 days with dosing volume of 10 mL·kg-1, the contents in caecum of rats were taken after anesthesia.Illumina MiSeq was used as the sequencing platform, the number of operational taxonomic units(OTUs), richness and diversity indexes, diversity of alpha and beta, differential phylum and genus of intestinal flora in V4 zone of 16S rRNA were comprehensively analyzed and evaluated. Result:Chaihu Longgu Mulitang could improve the number of OTUs, richness and diversity indexes of intestinal flora, imbalance of alpha and beta diversity of schizophrenic model rats.And this formula had a callback effect on 5 differential phyla of bacteria(Bacteroidetes, Acidobacteria, Proteobacteria, Firmicutes and TM7) and 20 genera of bacteria in schizophrenic model rats. Conclusion:Chaihu Longgu Mulitang plays an therapeutic effect on diversity of abnormal microflora in schizophrenic model rats, and this paper reveals the pathological mechanism of intestinal microflora in the state of schizophrenia by 16S rRNA technique.
