Cigarette smoking is associated with numerous diseases and poses a serious challenge to the current healthcare system worldwide. Smoking impacts both innate and adaptive immunity and plays dual roles in regulating immunity by either exacerbation of pathogenic immune responses or attenuation of defensive immunity. Adaptive immune cells affected by smoking(More)
A rapid, sensitive and selective UPLC/MS method using LTQ Orbitrap mass spectrometry was established for the analysis and characterization of the main biological components and their metabolites in rat plasma, urine and feces following oral administration of Lithocarpus polystachyus extract. In vivo, 22 flavonoid metabolites were observed in rat plasma, and(More)
The immunomodulatory effects of two new phlorizin metabolites, phloretin 4-O-β-d-glucuronide (1), 6-methoxyl-phloretin-2-O-β-d-glucuronide (2), together with phloretin-2-O-β-d-glucuronide (3) on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells were determined. 1-3 (1-5μg/ml) significantly inhibited the production of NO (p<0.01). At the(More)
Morinda officinalis is beneficial for the treatment of inflammatory bowel disease (IBD). The hairy root with higher genetic and biochemical stability cultured from M. officinalis might have similar effects to treat IBD. In this study, the main chemical composition of the root extracts of M. officinalis (MORE) native plant and the hairy root extract of M.(More)
The purpose of this study was to investigate the protective roles and mechanisms of Dendrobium officinale polysaccharides (DOPS) on secondary liver injury in acute colitis. Firstly, the mice model of secondary liver injury in acute colitis was induced by 4% Dextran sodium sulfate (DSS). Inflammatory cell model was established by LPS-stimulated RAW264.7(More)
