Exploring the of Effects of Different Doses of Elemene Emulsion Injection on Virus in Rat Feces Based on Metagenomic Sequencing Technology
Objective:To investigate the effects of different doses of elemene emulsion injection on virus in the feces of rats.Meth-ods:Eighteen specific pathogen-free healthy male Sprague-Dawley(SD)rats were randomly divided into three groups:low-dose el-emene emulsion injection group[L-EEI,20 mg/(kg·d)],high-dose elemene emulsion injection group[H-EEI,40 mg/(kg·d)]and Control group(equal volume of normal saline),with six rats in each group.After 14 days of continuous administration,fresh feces were collected for metagenomic sequencing,followed by bioinformatic analysis of the detected viruses.Results:Venn di-agram analysis showed that the number of unique viruses in control,L-EEI and H-EEI groups were 6,6 and 10,respectively,with 77 common viruses identified at the species level across the three groups.PCA analysis showed that the data of the L-EEI group were significantly different from those of the other groups(P=0.036 at the genus level,P=0.012 at the species level).NMDS a-nalysis showed that the degree of data aggregation in L-EEI and H-EEI groups was higher(genus level:Stress=0.093,species lev-el:Stress=0.129).A total of 10 viruses showed significant differences among the three groups(P<0.01).The effects of different doses of EEI on viral abundance could be divided into three categories:1)viral abundance was positively or negatively correlated with EEI dose;2)Compared with the control group,L-EEI increased virus abundance,but H-EEI had no significant effect on virus abundance;3)Compared with the control group,L-EEI caused a decrease in virus abundance,but H-EEI had no significant effect on virus abundance.Conclusion:Different doses of EEI could induce changes in the composition and structure of the virus in the feces of rats,and different viruses show varying sensitivities to different doses of EEI.
