Tris (1,3-dichloro-2-propyl) phosphate exposure disrupts the gut microbiome and its associated metabolites in mice.

Background: Tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) has been frequently detected in environmental media and biological samples. However, knowledge of its adverse health consequences is limited, and its impacts on the human gut microbiota, which play a key role in health and disease, remain unexplored.

Objectives: To better evaluate the potential risk of TDCIPP exposure in human health, we investigated the effects of TDCIPP on gut microbiome and gut metabolites in C57BL/6 mice.

NMR-Based Metabonomic Study Reveals Intervention Effects of Polydatin on Potassium Oxonate-Induced Hyperuricemia in Rats.

Previous studies have disclosed the antihyperuricemic effect of polydatin, a natural precursor of resveratrol; however, the mechanisms of action still remain elusive. The present study was undertaken to evaluate the therapeutic effects and the underlying mechanisms of polydatin on potassium oxonate-induced hyperuricemia in rats through metabonomic technology from a holistic view. Nuclear magnetic resonance (NMR) spectroscopy was applied to capture the metabolic changes in sera and urine collected from rats induced by hyperuricemia and polydatin treatment.

[Intervention effects of Jiaotai pills on PCPA-induced insomnia in rats].

To elucidate the intervention effects of Jiaotai pills(JTP) on p-chlorophenylalanine (PCPA)-induced insomnia in rats and its underlying mechanism, the insomnia model was established by single intraperitoneal injection with PCPA in rats. The locomotor activity of rats was observed, and the levels of nerve growth factor(NGF) in hypothalamus, hippocampus, prefrontal cortex and serum of rats were determined by using ELISA. Moreover, a proton nuclear magnetic resonance(¹H-NMR)-based metabonomic approach was developed to profile insomnia-related metabolites in rat serum and hippocampus and analyze the intervention effects of JTP on changes in underlying biomarkers related to locomotor activity, NGF and insomnia.

Therapeutic Effects of Chinese Medicine Herb Pair, Huzhang and Guizhi, on Monosodium Urate Crystal-Induced Gouty Arthritis in Rats Revealed by Anti-Inflammatory Assessments and NMR-Based Metabonomics.

The present study was undertaken to evaluate the therapeutic effects of Huzhang-Guizhi herb pair (HG), firstly included in Hu-Zhang Power documented in Taiping Shenghui Fang, on monosodium urate (MSU) crystals-induced gouty arthritis in rats. We found that pretreatment with HG in rats with gouty arthritis could significantly attenuate the ankle joint swelling, and this beneficial antigout effect might be mediated, at least in part, by inhibiting tumor necrosis factor-alpha (TNF-α) and interleukin-1 beta (IL-1β) production in synovial fluid as well as nuclear transcription factor-κB p65 (NF-κB p65) protein expression in synovial tissue. Moreover, metabonomic analysis demonstrated that 5 and 6 potential biomarkers associated with gouty arthritis in plasma and urine, respectively, which were mainly involved in energy metabolism, amino acid metabolism, and gut microbe metabolism, were identified.

[Metabonomics Study on Urine 1H-NMR in Chronic Superficial Gastritis Patients with Pi-qi Deficiency Syndrome/Pi-Wei Dampness-heat Syndrome].

Objective: To observe metabolomic changes in urine of chronic superficial gastritis (CSG) patients with Pi-qi deficiency syndrome (PQDS) or Pi-Wei dampness-heat syndrome (PWDHS), thereby providing scientific evidence for syndrome typing of them.

Methods: Urine samples were collected from CSG patients with PQDS/PWDHS and healthy volunteers, 10 in each group. Proton nuclear magnetic resonance spectroscopy (1H-NMR) based metabonomic analysis was performed on urine samples.

Icariin reverses corticosterone-induced depression-like behavior, decrease in hippocampal brain-derived neurotrophic factor (BDNF) and metabolic network disturbances revealed by NMR-based metabonomics in rats.

Previously published reports have revealed the antidepressant-like effects of icariin in a chronic mild stress model of depression and in a social defeat stress model in mice. However, the therapeutic effect of icariin in an animal model of glucocorticoid-induced depression remains unclear. This study aimed to investigate antidepressant-like effect and the possible mechanisms of icariin in a rat model of corticosterone (CORT)-induced depression by using a combination of behavioral and biochemical assessments and NMR-based metabonomics.

NMR-Based Metabonomic Studies on Stomach Heat and Cold Syndromes and Intervention Effects of the Corresponding Formulas.

Zuojin Wan (ZJW) and Lizhong Wan (LZW) have been widely used in the treatment of Stomach heat and cold syndrome (SH and SC), respectively.
