Association between serum cartilage oligomeric matrix protein and coronary artery calcification in maintenance hemodialysis patients.

Background: Coronary artery calcification (CAC) is common in end-stage renal disease (ESRD) patients, and the extent of CAC is closely related to cardiovascular outcomes in ESRD patients. Cartilage oligomeric matrix protein (COMP), as a component of the vascular matrix, has been found to be an inhibitor of arterial calcification in basic studies. However, there is no clinical research on the correlation between COMP and CAC in maintenance hemodialysis (MHD) patients.

Retraction statement: ‘Urotensin II inhibits autophagy in renal tubular epithelial cells and induces extracellular matrix production in early diabetic mice’ by Guan‐Jong Chen, Fei Wu, Xin‐Xin Pang, Ai‐Hua Zhang, Jun‐Bao Shi, Min Lu and Chao‐Shu Tang.

Aims/introduction: Urotensin II (UII) and autophagy have been considered as important components in the pathogenesis of diabetic nephropathy. The present study explores whether UII can regulate autophagy in the kidney, and its effect in diabetes.

Materials And Methods: Immunohistochemistry and western blot were carried out on the kidney tissues of diabetic UII receptor (UT) gene knockout mice, wild-type diabetic mice and normal control mice.

[Analysis of clinical state for arteriosclerosis obliterans in lower extremity of diabetic patients on peritoneal dialysis].

Objective: To investigate the prevalence of arteriosclerosis obliterans in lower extremity and its influence factors in diabetic patients on peritoneal dialysis.

Method: In this single center cross-sectional study, 74 with diabetic patients on peritoneal dialysis were recruited. The general information, dialysis program, laboratory examination and dialysis adequacy test results were recorded.
