Urine Metabolomics Analysis of Effect of Dendrobii Officinalis Caulis Aqueous Extract on Gastric Precancerous Lesions
Objective: To study on the effect of Dendrobii Officinalis Caulis aqueous extract on endogenous metabolites in urine of rats with gastric precancerous lesions. Method: Wistar rats were randomly divided into normal group
Dendrobii Officinalis Caulis aqueous extract(DOE) group
model group
N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) +DOE groups at low
middle and high dosages.After 2 weeks of prophylactic administration of DOE
100 mg·L-1 MNNG aqueous solution was given to the free drink
and the model was made as the drug was administered.In addition
in the first 6 weeks
rats were given 1 mL of 10% NaCl every 3 days for inducing gastric precancerous lesions.After 7 months of modeling
the rat urine was collected and the rats were sacrificed for gastric tissue.UPLC-Q-TOF-MS was used to detect the changes of urine metabolic profile in rats. Result: By comparing the histopathological results of gastric tissues in each group
it was found that DOE could reduce the intestinal metaplasia and make the pathological degree stay in the stage of mild-moderate dysplasia and mild intestinal metaplasia.In positive and negative ion modes
6 and 15 differential marker compounds were screened
respectively.Metabolites were mainly related to porphyrin metabolism
tryptophan metabolism
folic acid and pterin biosynthetic metabolism
galactose metabolism and arachidonic acid metabolism
of which porphyrin metabolism was the most relevant. Conclusion: DOE can block the progression of gastric precancerous lesions
its mechanism may be related to porphyrin metabolism
tryptophan metabolism
folic acid and pterin biosynthesis
galactose metabolism and arachidonic acid metabolism.
