[Effect of admission blood urea and creatinine levels on mortality in elderly patients with hip fracture].

Objective: To observe the effect of admission blood urea and creatinine levels on mortality in elderly patients with hip fracture.

Methods: Form January 2013 to December 2014, 767 elder patients with hip fracture were treated in our hospital including 253 males and 514 females, aged from 65 to 96 years old with an average of(75.67±6.

Downregulation of miR-221-3p contributes to IL-1β-induced cartilage degradation by directly targeting the SDF1/CXCR4 signaling pathway.

Osteoarthritis (OA) is characterized by degradation of chondrocyte extracellular matrix (ECM). Accumulating evidence suggests that microRNAs (miRNAs) are associated with OA, but little is known of their function in chondrocyte ECM degradation. The objective of this study was to investigate the expression and function of miRNAs in OA.
