ABSTRACT

Objective:

To explore the difference of intestinal flora between the patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang and the healthy population.

Method:

The fecal samples of 9 patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang from the first affiliated hospital of Guangzhou university of traditional Chinese medicine in 2018 were selected as observation group,and 6 stool samples from healthy subjects were selected as the control group.The total bacterial DNA was extracted from the two groups of samples,amplified according to the 16S rRNA V4 region,and paired-end sequencing was performed on the Illumina MiSeq platform.The sequencing results were analyzed by bioinformatics analysis software.The flora composition and structure of the samples from two groups were compared.

Result:

Venn analysis of operational taxonomic units(OTU) showed significant difference in OTU numbers between the observation group and control group.Partial least squares-discriminant analysis(PLS-DA) showed that there was a significant difference in the composition of intestinal flora between patients with acute cerebral hemorrhage and healthy subjects.On the analysis of species and abundance,at the classification level of phylum,compared with the control group,the ratio of relative abundance values of Firmicutes and Bacteroidetes(F/B) in the observation group was significantly increased,and the relative abundance of Verrucomicrobia was significantly decreased(PPrevotella,Bacteroides,Akkermansia,Blautia and Acidaminococcus(PPBacteroides and Prevotella(B/P) in the observation group was significantly higher than that of the control group;at the classification level of species,there were significant differences between the two groups in P. copri,A. muciniphila,B. ovatus,B. fragilis and Ruminococcus callidus(PP

Conclusion:

Acute cerebral hemorrhage due to hyperactivity of liver-Yang is associated with structural disorder of intestinal flora,which is closely related to the decrease in relative abundance of P. copri and A. muciniphila.
