To investigate the effects and molecular mechanisms of wedelolactone (WEL) on high glucose-induced injury of human retinal vascular endothelial cells (HRECs). The cell injury model was established by incubating HRECs with 30 mmol/L glucose for 24 hour. HRECs were divided into control (Con) group, high glucose (HG) group, HG + WEL-low dose (L) group, HG + WEL-medium dose (M), HG + WEL-high dose (H) group, HG + miR-NC group, HG + miR-190 group, HG + WEL + antimiR-NC group, HG + WEL + antimiR-190 group. ⋯ Compared with the HG + miR-NC group, the levels of ROS and MDA in HG + miR-190 group were significantly reduced (P < .01), SOD activity was significantly increased (P < .01), and apoptosis rate was significantly reduced (P < .05). Compared with the HG + WEL + antimiR-NC group, the ROS level and MDA content in the HG + WEL + antimiR-190 group were significantly increased (P < .05), SOD activity was significantly decreased (P < .05), and apoptosis rate was significantly increased (P < .05). Wedelolactone can attenuate high glucose-induced HRECs apoptosis and oxidative stress by up-regulating miR-190 expression.

Observational Study
Anthrometric dimensions and their impact on cardiovascular risk factors.
Central obesity is an important risk factor for cardiovascular disease. The abdominal subcutaneous adipose tissue thickness (ASATT) can be used to evaluate central obesity. The objective of this study was to compare ASATT with cardiovascular risk factors and other anthropometric parameters to show that ASATT can be a useful tool for the early assessment of heart disease risk. ⋯ In the male group, the aortic inner surface atheroma density was positively correlated with ASATT (P < .05). In both sexes, there was a positive correlation (P < .05) between ASATT and heart weight; however, no such correlation was observed with right and left ventricular wall thickness (P > .05). ASATT is related to other anthropometric measurements, atherosclerosis of critical vessels, and heart weight, and can be used to scan the patient population for heart disease risk assessment with noninvasive methods.

To evaluate left atrial volume and function in patients with paroxysmal atrial fibrillation (AF) combined with left atrial appendage thrombosis and patients with paroxysmal AF without left atrial appendage thrombosis by 3-dimensional speckle tracking imaging (3D-STI), and to explore the application value of this set of parameters in the evaluation of left atrial function in patients with paroxysmal AF. ⋯ Real-time 3-dimensional spot tracking imaging (3D-STI) can evaluate the changes in left atrial volume and function in patients with paroxysmal AF, and has a certain reference value for clinical judgment of disease progression and prognosis.

Although observational studies have found both a positive and negative association between depression and hypercholesterolemia, the findings are mixed and contradictory. To our knowledge, this is the first study that employs the bidirectional Mendelian randomization (MR) and multivariable MR analysis with extensive genome-wide association studies (GWAS) data to examine the causal effect between depression and hypercholesterolemia. Using summary statistics obtained from GWAS of individuals with European ancestry, we utilize a bidirectional 2-sample MR approach to explore the potential causal association between hypercholesterolemia and depressive symptoms. ⋯ Neither the leave-one-out sensitivity test nor the funnel plots revealed any outliers. In both the unadjusted and adjusted estimates, depression has a consistent direct causal effect on hypercholesterolemia. Our study has led to an improved comprehension of the causal connections between hypercholesterolemia and depression, which could aid in the prevention and treatment of hypercholesterolemia.

Crohn's disease and ulcerative colitis are forms of inflammatory bowel disease affecting approximately 1% of the population. Their typical features include chronic diarrhea, abdominal pain, and weight loss. Extraintestinal manifestations may coincide with or precede the diagnosis of these diseases. Primary sclerosing cholangitis is one such extraintestinal manifestation. Although many papers on this field have been published, bibliometric analysis still needs to be conducted. This article summarizes the current research progress through a bibliometric study, provides an overview of the research status in this field, and analyzes recent research trends. ⋯ Research on the association between inflammatory bowel disease and primary sclerosing cholangitis is steadily advancing, with the United States leading in publication output globally. China needs to invest more in research in this area, and collaboration among institutions should be strengthened. The research hotspots revolve around the association between inflammatory bowel disease and primary sclerosing cholangitis, gut microbiota, and other fields.
