In this study, UHPLC-Q-TOF-MS and UHPLC-QQQ-MS were adopted cooperatively to establish a method synchronously detecting 10 kinds of LFS monomers in rat plasma samples.

Dynamic modulation of gut microbiota improves post-myocardial infarct tissue repair in rats via butyric acid-mediated histone deacetylase inhibition.

The complex and dynamic population of gut microbiota exerts a marked influence on the host during homeostasis and disease. Imbalance of gut microbiota metabolites may lead to cardiac dysfunction in patients with heart failure, which is related to myocardial infarction(MI) severity. However, the role of gut microbiota in the repair process after MI has rarely been reported.

Pharmacodynamic effects and molecular mechanisms of lignans from Schisandra chinensis Turcz. (Baill.), a current review.

Fruit of Schisandra chinensis Turcz. (Baill.) (S.

Proteomic Analysis Reveals the Effect of Trichostatin A and Bone Marrow-Derived Dendritic Cells on the Fatty Acid Metabolism of NIH3T3 Cells under Oxygen-Glucose Deprivation Conditions.

Fibroblasts mediate acute wound healing and long-term tissue remodeling with scarring after tissue injury. Following myocardial infarction (MI), necrotized cardiomyocytes become replaced by secreted extracellular matrix proteins produced by fibroblasts. Dendritic cells (DCs) can migrate from the bone marrow to the infarct areas and infarct border areas to mediate collagen accumulation after MI.

Cardiac Transcriptome Analysis Reveals Nr4a1 Mediated Glucose Metabolism Dysregulation in Response to High-Fat Diet.

Obesity is associated with an increased risk of developing cardiovascular disease (CVD), with limited alterations in cardiac genomic characteristics known. Cardiac transcriptome analysis was conducted to profile gene signatures in high-fat diet (HFD)-induced obese mice. A total of 184 differentially expressed genes (DEGs) were identified between groups.

Non-target metabonomic method provided new insights on the therapeutical mechanism of Gancao Fuzi decoction on rheumatoid arthritis rats.

Gancao Fuzi decoction (GFD) is a classic Chinese medicine formula for the treatment of rheumatic and rheumatoid arthritis. The main active components of GFD are alkaloids, flavonoids and saponins. This study aimed to clarify the pharmacodynamic effects of the active components in GFD and investigate the mechanism of them treating rheumatoid arthritis rats by the method of metabonomics.

Study on Urine Metabolic Profile of Aβ25-35-Induced Alzheimer's Disease Using UHPLC-Q-TOF-MS.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder, with no effective method for its treatment so far. The pathogenesis of AD has been reported, but the endogenous metabolic profile and disease-related biomarkers are still not clear. To better understand AD, an AD model induced by injecting β-amyloid 25-35 (Aβ 25-35) solution into bilateral hippocampus was developed on Sprague-Dawley rats.

Urinary metabolomics study on the anti-inflammation effects of flavonoids obtained from Glycyrrhiza.

Rheumatoid arthritis (RA) is a chronic disease with pain, swelling, and limitation in the motion and function of multiple joints thus leading to high disability. Previous studies have shown that flavonoids and saponins are the most abundant and active constituents in Glycyrrhiza, which possess a wide range of pharmacological effects such as anti-inflammatory, antioxidant and anti-bacteria. But the mechanisms of those actions are not entirely clear.

Urinary metabolomic study of the antagonistic effect of P. ginseng in rats with estrogen decline using ultra performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.

Estrogens are biologically active steroid hormones mainly released from the ovary by ovarian secretion of estrogen into the circulating blood to regulate or function at the distal target. Estrogens play an important role in the central nervous system, cardiovascular system and immune system, especially for post-menopausal women. Panax ginseng Mayer has been reported to relieve women's menopausal symptoms and affect estrogen activities.

Fecal Metabolomics of Type 2 Diabetic Rats and Treatment with Gardenia jasminoides Ellis Based on Mass Spectrometry Technique.

Modern studies have indicated Gardenia jasminoides Ellis (G. jasminoides) showed positive effect in treating type 2 diabetes mellitus (T2DM). In this study, 60 streptozotocin-induced T2DM rats were divided into four groups: type 2 diabetes control group, geniposide-treated group, total iridoid glycosides-treated group, and crude extraction of gardenlae fructus-treated group.

Metabonomics study of the therapeutic mechanism of fenugreek galactomannan on diabetic hyperglycemia in rats, by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.

Fenugreek is a traditional plant for the treatment of diabetes. Galactomannan, an active major component in fenugreek seeds, has shown hypoglycemic activity. The present study was performed to investigate the therapeutic mechanism underlying fenugreek galactomannan (F-GAL) in treating diabetes, using a metabonomics approach based on ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS).
