A UPLC-MS/MS method for simultaneous determination of arachidonic acid, stearic acid, and related endocannabinoids in human plasma.

Endocannabinoids (eCBs) exert considerable influence over energy metabolism, lipid metabolism, and glucose metabolism within the human body. Among the most biologically active cannabinoids identified thus far are 2-arachidonoylglycerol (2-AG), arachidonoyl ethanolamide (AEA), 1-stearoylglycerol (1-SRG), and stearoyl ethanolamide (SEA), which are derived from arachidonic acid (AA) and stearic acid (SA). However, despite the unique in bioactivities exhibited by eCBs, their determination in plasma has been hindered by the lack of sensitive analytical methods.

[Lipid-lowering effect of drug pair Scutellariae Radix-Coptidis Rhizoma based on lipomics].

This study investigated the mechanism of action of Scutellariae Radix-Coptidis Rhizoma(SR-CR) in intervening in non-alcoholic fatty liver disease(NAFLD) in rats based on lipidomics. Thirty-six SD rats were divided into a control group, a model group, SR-CR groups of different doses, and a simvastatin group, with six rats in each group. Rats in the control group were fed on a normal diet, while those in the remaining groups were fed on a high-lipid diet.

Banxia Xiexin decoction ameliorates dextran sulfate sodium (DSS)-induced ulcerative colitis via inhibiting serine-threonine protein kinase (Akt)/mitogen-activated protein kinase (MAPK) signaling pathway.

Banxia Xiexin decoction (BXD), a traditional Chinese medicine, was widely used in treating ulcerative colitis (UC). However, the active components of BXD and its mechanism in UC remain elusive. Therefore, we used network pharmacology in vivo experiments, molecular docking, and surface plasmon resonance strategy (SPR) to uncover BXD's potential mechanism.

Comparative pharmacokinetics of four major flavonoids in normal and chronic gastritis rats after oral administration of different combinations of Banxia Xiexin decoction.

Chronic gastritis (CG) has become a major threat to human health. Banxia Xiexin Decoction (BXXXD) has been used clinically to treat gastritis by acting on the spleen and stomach for thousands of years. Baicalin, wogonoside, liquiritin and liquiritigenin are the main bioactive flavonoids of BXXXD.
