Evaluation of drug interactions of Saposhnikoviae Radix and its major components with astragaloside IV and paeoniflorin using in vitro and in vivo experiments.

Saposhnikoviae Radix (SR) may enhance the pharmacodynamics of Huangqi Chifeng Tang (HQCFT) in the treatment of cerebral infarction according to our previous research, but the underlying mechanism is unknown. Herein, an in vivo pharmacokinetic assay in rats and in vitro MDCK-MDR1 cell assays were used to investigate the possible mechanism of SR, its main components, and its interactions with Astragali Radix (AR) and Paeoniae Radix (PR). An ultrahigh-performance liquid chromatography-tandem mass spectrometry (UPLC‒MS/MS)-based analytical method for quantifying astragaloside IV (ASIV) and paeoniflorin (PAE) in microdialysis and transport samples was developed.

Integrated network pharmacology and phosphoproteomic analyses of Baichanting in Parkinson's disease model mice.

The incidence rate of Parkinson's disease (PD) is increasing yearly. Neuronal apoptosis caused by abnormal protein phosphorylation is closely related to the pathogenesis of Parkinson's disease. At present, few PD-specific apoptosis pathways have been revealed.

[Mechanism of acteoside in prevention and treatment of gouty arthritis based on liver metabolomics].

This study aims to reveal the effect of acteoside on gouty arthritis(GA) in rats based on liver metabolomics. The ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was employed to search for the potential biomarkers and metabolic pathways. SD rats were randomly assigned into blank, model, colchicine(0.

Anti-inflammation effects of the total saponin fraction from Dioscorea nipponica Makino on rats with gouty arthritis by influencing MAPK signalling pathway.

Background: Dioscorea nipponica Makino is widely used in traditional Chinese medicine to treat gouty arthritis.

Methods: Sixty male Wistar rats were divided into six groups: the normal group, model group, colchicine group (COL) and three total saponin groups (RDN) (high dose [160 mg/kg], middle dose [80 mg/kg] and low dose [40 mg/kg]). HE staining was used to detect the histopathologic changes of the synovial tissue of joint.

[Liver metabonomics of acute gouty arthritis treated by Diosocorea nipponica].

To explore the prevention and protection effect of Diosocorea nipponica (DNM)) on acute gouty arthritis (AGA) rats based on liver metabonomics, and find potential biomarkers and related pathways. AGA model rats were induced by monosodium urate crystal suspension. UPLC-TOF-MS coupled with pattern recognition technique was employed to find out the potential biomarkers and related metabolic pathways.

Anti-inflammatory Effect of Total Saponin Fraction from Dioscorea nipponica Makino on Gouty Arthritis and Its Influence on NALP3 Inflammasome.

Objective: To investigate the mechanism of Chinese herbal medicine Dioscorea nipponica for the treatment of monosodium urate crystals-induced gouty arthritis (GA) in rats.

Methods: Sixty male Wistar rats were divided into 6 groups: normal, model, indomethacin and three total saponin (900, 300 and 100 mg/kg) groups. The liver, kidney and serum levels of lysosomal enzymes, antioxidant capacities, and inflammatory factors were measured.

[Study on potential effect of Dioscorea nipponica in intervening peripheral system of rats based on metabonomic analysis].

To study the potential effect of Dioscorea nipponica(DN) in intervening peripheral system of rats based on metabolomic analysis. The identification of the potential intervention targets of DN in peripheral system may facilitate its safe application and therapeutic potential exploitation. Totally 20 male SD rats were randomly divided into the blank group and the DN-treated groups, with 10 rates in each group.

Total saponins from Discorea nipponica makino ameliorate urate excretion in hyperuricemic rats.

Objective: The objective was to study the mechanism of reducing level of the uric acid by rhizoma dioscoreae nipponese.

Materials And Methods: A total of 40 rats were divided into four groups: A normal group, hyperuricemia group, benzbromarone group (9 mg/kg) and total saponins from rhizoma dioscoreae nipponese (TDN) group (40 mg/kg). Adenine (100 mg/kg) and ethambutol (250 mg/kg) were used to induce hyperuricemic rats.

Total saponins from Discorea nipponica ameliorate urate excretion in hyperuricemic mice.

Rhizoma Dioscoreae Nipponicae, from Discorea nipponica, is a widely used traditional Chinese herb. It is used to treat arthroncus, arthrodynia, and arthritis. Hyperuricemia is an important foundation of gouty arthritis.

Therapeutic effect of Rhizoma Dioscoreae Nipponicae on gouty arthritis based on the SDF-1/CXCR 4 and p38 MAPK pathway: an in vivo and in vitro study.

Rhizoma Dioscoreae Nipponicae (RDN) is a widely used traditional Chinese herb, which is used to treat arthroncus, arthrodynia and arthritis. As is known to us, inflammatory mechanisms have played an important role in the occurrence, course and prognosis of gouty arthritis (GA). The aim of this study was to determine the characteristic expressed proteins of synovium in GA rat and synovial cell.
