Multivessel disease (MVD) is an independent risk factor for poor prognosis in acute myocardial infarction patients. Although several global risk scoring systems (RSS) are in use in clinical practice, there is no dedicated RSS for MVD in ST-segment elevation myocardial infarction (STEMI). The primary objective of this study is to develop a novel RSS to estimate the prognosis of patients with MVD in STEMI.

SKI306X was previously reported to have good anti-inflammatory and analgesic efficacy in various studies. To determine its mode of action, an investigation was carried out for some representative mediators. Arachidonic acid metabolism and its products are particularly important in inflammation and pain.

SKI306X was previously found to have cartilage protective effects in the experimental osteoarthritis (OA) model. To investigate the chondro-protective benefits of SKI306X for its capacity in altering changes in cartilage metabolism and molecular mechanisms of cartilage protective action, SKI306X is studied in rabbit cartilage explants culture. To investigate the protective effect of SKI306X on cartilage catabolism, we assessed collagen degradation in rabbit cartilage explants treated with interleukin-1alpha up to 3 weeks.

This study was undertaken to elucidate the mechanism of anti-inflammatory action of gentianine, a constituent of Gentiana Macrophylla. The effects of gentianine on lipopolysacharide (LPS)-induced production of pro-inflammatory cytokines were investigated in male Sprague-Dawley rats. For the first time, we found that oral administration of gentianine (10-100 mg/kg) suppressed the increases in tumor necrosis factor-alpha (TNF-alpha) (ED(50), 37.
