Study on the Effect of Huanglian Jiedu Decoction on the Composition of Gut Microflora in SD Rats Based on 16S rRNA Sequencing.

ABSTRACT:

Objective

To study the effects of Huanglian Jiedu Decoction (HJD) on gut microflora of SD rats.

Method

After 3 days of adaptive feeding, 36 rats were randomly divided into 4 groups, namely, the normal control group (NC, 10?mL/kg, distilled water), high_HJD dose group (H_HJD, 6.25?g/kg, weight ratio between crude drug and rat), medium_HJD dose group (M_HJD, 3.125?g/kg), and low_HJD dose group (L_HJD, 1.56?g/kg), and each group consisted of 9 mice. The HJD groups were then treated with orally administered HJD for 21 days, while the NC group was treated with distilled water. After 7 days, 14 days, and 21 days of the experiment and after 12 hours of fasting and water deprivation, 3 SD rats in each group were randomly sacrificed by cervical dislocation and sterile operation to collect stool faces. Sample DNA was extracted by Fecal total DNA extraction kit, sequenced using Illumina MiSeq platform, and analyzed.

Results

The abundance of Romboutsia, Turicibacter, Lactobacillus, and Gemella decreased, while that of Escherichia_Shigella, Coprobacillus, Blautia, Akkermansia, Klebsiella, Rhodococcus, Parabacteroides, Citrobacter, Enterococcus, Bacteroides, and Erysipelotrichaceae_incertae_sedis increased after using H_HJD. The abundance of Gemella, Turicibacter, Romboutsia, and Lactobacillus decreased, while that of Blautia, Akkermansia, Escherichia_Shigella, Thiobacillus, Rothia, Enterococcus, Lactobacillus, and Erysipelotrichaceae-incertae-sedis increased after using M_HJD. The abundance of Romboutsia, Turicibacter, Lactobacillus, and Gemella decreased, while that of Escherichia_Shigella, Bacteroides, Akkermansia, Enterococcus, Rhodococcus, Parabacteroides, Desulfovibrio, Blautia, Fusobacterium, Rothia, and Streptococcus increased after using L_HJD.

Conclusion

HJD can regulate gut microbiota, and its effect varies with different dosage and duration of medication.

Project description:"Shanghuo" ("excessive internal heat") is caused by exuberant endogenous fire, which does not have a comprehensive and systematic traditional Chinese medicine theory. In previous study, we had evaluated the therapeutic effect of Huanglian Jiedu Decoction (HLJDD) (granule) on patients with "Shanghuo", however, the specific mechanism was not clear, which need further exploration. To explain its intervention mechanism, we select 57 patients with oral diseases caused by "Shanghuo" and 20 health volunteers to divide into oral disease group, HLJDD intervention group and healthy control group. Firstly, biochemical indicators before and after HLJDD intervention are detected, such as inflammatory factors, oxidative stress factors and energy metabolism factors. The results exhibit that HLJDD significantly decreases indicators succinic acid (p < 0.001); tumor necrosis factor-alpha, adenosine triphosphate, citric acid (p < 0.01); interleukin-8 (IL-8), 4-hydroxynonenal, pyruvic acid, lactate dehydrogenase (p < 0.05). The levels of glucocorticoid, adrenocorticotropic hormone (p < 0.01); lactic acid, IL-4, IL-10 (p < 0.05) significantly increase after HLJDD intervention. In addition, we adopt multi-omics analysis approach to investigate the potential biomarkers. Nontargeted metabolomics demonstrate that the levels of 7 differential metabolites approach that in the healthy control group after HLJDD intervention, which are correlated with histidine metabolism, beta-alanine metabolism and sphingolipid metabolism through metabolic pathway analysis. Targeted lipidomics results and receiver operating characteristic curve analysis show that 13 differential lipids are identified in the three groups mainly focuse on lysophosphatidylcholines, lysophosphatidylethanolamines. Finally, the network associations of those differential biomarkers reveal the regulation of adenosine triphosphate and tricarboxylic acid cycle play essential role in the therapeutic effect mechanism of HLJDD in "Shanghuo". The study has laid the foundation for further revealing the mechanism and finding clinical biomarkers related to "Shanghuo".

Project description:Traditional Chinese medicine (TCM) formulas treat complex diseases through combined botanical drugs which follow specific compatibility rules to reduce toxicity and increase efficiency. "Jun, Chen, Zuo and Shi" is one of most used compatibility rules in the combination of botanical drugs. However, due to the deficiency of traditional research methods, the quantified theoretical basis of herbal compatibility including principles of "Jun, Chen, Zuo and Shi" are still unclear. Network pharmacology is a new strategy based on system biology and multi-disciplines, which can systematically and comprehensively observe the intervention of drugs on disease networks, and is especially suitable for the research of TCM in the treatment of complex diseases. In this study, we systematically decoded the "Jun, Chen, Zuo and Shi" rules of Huanglian Jiedu Decoction (HJD) in the treatment of diseases for the first time. This interpretation method considered three levels of data. The data in the first level mainly depicts the characteristics of each component in single botanical drug of HJD, include the physical and chemical properties of component, ADME properties and functional enrichment analysis of component targets. The second level data is the characterization of component-target-protein (C-T-P) network in the whole protein-protein interaction (PPI) network, mainly include the characterization of degree and key communities in C-T-P network. The third level data is the characterization of intervention propagation properties of HJD in the treatment of different complex diseases, mainly include target coverage of pathogenic genes and propagation coefficient of intervention effect between target proteins and pathogenic genes. Finally, our method was validated by metabolic data, which could be used to detect the components absorbed into blood. This research shows the scientific basis of "Jun-Chen-Zuo-Shi" from a multi-dimensional perspective, and provides a good methodological reference for the subsequent interpretation of key components and speculation mechanism of the formula.
