Representative work: BACKGROUND The objective of this study was to study the anti-inflammatory effect and possibly involved molecular mechanisms of matrine on oxidized low-density lipoprotein (ox-LDL)-exposed macrophages. MATERIAL AND METHODS Cultured human macrophages (THP-1 cell line) were exposed to ox-LDL at final concentrations of 0, 25, 50, and 100 μg/mL. Several cells were then treated with matrine at serial diluted concentrations. 2,7-Dichlorodi-hydrofluorescein diacetate (DCFH-DA) staining was used to evaluate reactive oxygen species (ROS) production; a colorimetric method was used to determine the cellular antioxidant capacity; production of pro-inflammatory cytokines interleukin (IL)18 and tumor necro Objective This study aimed to establish a model embraced electromechanical coupling time (EMC-T) and assess the value of the model for the prediction of heart failure (HF) in patients with hypertrophic cardiomyopathy (HCM). Materials and Methods Data on 82 patients with HCM at Shaanxi Provincial People’s Hospital between February 2019 and November 2021 were collected and then formed the training dataset ( n = 82). Data were used to screen predictors of HF using univariate and multivariate analyses. Predictors were implemented to discover the optimal cut-off value, were incorporated into a model, and shown as a nomogram. The cumulative HF curve was calculated using the Kaplan–Meier method. Ad
