Intervention Effect of Dachuanxiong Fang Multi-component Preparation on Acute Migraine Rat Model by Urine Metabolomics
To investigate the intervention effect of Dachuanxiong Fang multi-component preparation on acute migraine rats
in order to explore the possible mechanism by using urine metabolomics technology.
Method:
2
The forty SD rats were randomly divided into 5 groups (
n
=8)
control group
model group
low-dose Dachuanxiong Fang multi-component preparation (DCXF) group (0.19 g·kg
-1
)
medium-dose DCXF group (0.37 g·kg
-1
)
and high-dose DCXF group (0.74 g·kg
-1
). Rats were subcutaneously injected with 10 mg·kg
-1
nitroglycerin for modeling
and Dachuanxiong Fang multi-component preparation was administered through intragastric administration. After half an hour of administration
blood was collected from the abdominal aorta
and the content of 5-hydroxytryptamine (5-HT)
5-hydroxyindole-3-acetic acid (5-HIAA)
nitric oxide (NO)
nitric oxide synthase (NOS)
calcitonlin gene related peplide (CGRP)
dopamine(DA) in plasma were determined by enzyme-linked immuno sorbent assay (ELISA) kits. The contents of 5-HT and NOS in the hypothalamus and brainstem of the control group and the model group were analyzed
and the average optical density value was used for statistical analysis. UPLC-TOF/MS combined with principal component analysis (PCA) analysis was used to analyze different groups of rats and discover differential metabolites. Differential metabolites were analyzed by MetaboAnalyst 3.0 software for possible metabolic pathways.
Result:
2
After modeling
compared with the control group
the content of neurotransmitters in the model group was significantly increased (
P
<
0.01). After the intervention with Dachuanxiong Fang multi-component preparation
compared with the model group
the content of neurotransmitters was significantly decreased (
P
<
0.05
P
<
0.01). Based on UPLC-TOF/MS analysis
10 potential biomarkers were found. After the intervention with Dachuanxiong multi-component preparation
the contents of tryptophan and proline were down-regulated
while the contents of gamma-aminobutyric acid(GABA)
lactic acid and
β
-hydroxybutyrate showed an upward trend. According to the metabolic pathway prediction study
metabolic pathways with a higher correlation were found to be alanine
aspartic acid and glutamate metabolism
propionic acid metabolism
nitrogen metabolism and tryptophan metabolism.
Conclusion:
2
The possible metabolism pathway of Dachuanxiong Fang multi-component preparation is mainly amino acid metabolism in urine
and kynurenine is also the product of tryptophan metabolism pathway. The kynurenine metabolic pathway is also one of the main pathways of tryptophan metabolism.
