Autophagy is a type of cellular catabolic degradation response to nutrient starvation or metabolic stress. The main function of autophagy is to maintain intracellular metabolic homeostasis through degradation of unfolded or aggregated proteins and organelles. Although autophagic regulation is a complicated process, solid evidence demonstrates that the(More)
OBJECTIVE Infection is one of possible complications after prosthetic material hernia repair surgery. Antibiotic prophylaxis is applied routinely in China, but its effect is still controversial. The present study aims to offer direct clinical evidence on prevention of infection after tension-free inguinal hernia repair. METHODS A total of 1,200 cases with(More)
Three new triterpenoid saponins 3, 4 and 5, together with two known saponins, ardisiacrispin B (1) and ardisiacrispin A (2), were isolated from the whole plants of Ardisia pusilla A. DC. Their structures were elucidated by extensive spectral analysis and chemical evidence. Compound 3 is a hexaglycoside with a 13,28-epoxyoleanane type aglycone, while both 4(More)
Multidrug-resistant Acinetobacter baumannii becomes an increasing challenge due to the overuse of antibiotics. Combination therapies are considered as effective options to overcome this matter. The present study was to investigate the synergistic activity of meropenem combined with other antibiotics in vitro and in vivo. Checkerboard assay and time-kill(More)
Danshensu, as the effective component of Salvia miltiorrhiza (Danshen), has been widely used in clinic for treatment of cardiovascular diseases in China. In the present study, we aimed to confirm the cardioprotective effect of Danshensu from myocardial ischemia/reperfusion (MI/R) injury in vivo, and investigate the potential molecular mechanisms against(More)
AIM To investigate the effects of safflor yellow A (SYA), a flavonoid extracted from Carthamus tinctorius L, on cultured rat cardiomyocytes exposed to anoxia/reoxygenation (A/R). METHODS Primary cultured neonatal rat cardiomyocytes were exposed to anoxia for 3 h followed by reoxygenation for 6 h. The cell viability was measured using MTT assay. The(More)
ETHNOPHARMACOLOGICAL RELEVANCE Combination of Radix Astragali (Huangqi) and Carthamus tinctorius L. (Honghua) has been extensively used as traditional herb medicine in China for the treatment of stroke and myocardial ischemia diseases with Qi deficiency and blood stasis (QDBS) syndrome. AIM To investigate the effect of Huangqi-Honghua combination (HH) and(More)
A highly sensitive and specific liquid chromatography coupled with tandem mass spectrometric (LC-MS/MS) method has been developed and validated for the simultaneous determination of lansoprazole and its metabolites 5'-hydroxy lansoprazole and lansoprazole sulphone. The detection was operated with multiple reaction-monitoring (MRM) using the electrospray(More)
Diabetes is a major health problem worldwide, and metformin, a traditional oral anti-hyperglycemic drug, is now believed to be the most widely prescribed antidiabetic drug. Metformin acts primarily by inhibiting hepatic glucose production and improving insulin sensitivity. Metformin is absorbed predominately by the small intestine and excreted in an(More)
Stroke is a complex disease involved oxidative stress-related pathways in its pathogenesis. The nuclear factor erythroid-2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway has been considered a potential target for neuroprotection in stroke. Acetyl-11-Keto-β-Boswellic Acid (AKBA) is an active triterpenoid compound from the extract of Boswellia(More)
