Gene Delivery of Calreticulin Anti-Angiogenic Domain Attenuates the Development of Choroidal Neovascularization in Rats.

Choroidal neovascularization (CNV) is a common pathological feature in neovascular age-related macular degeneration, which is the leading cause of vision loss among elderly populations in developed countries. This study evaluated the effect of a novel endogenous inhibitor of angiogenesis, calreticulin anti-angiogenic domain (CAD), subconjunctivally delivered by an adenoviral vector (Ad-CAD) in a rat model of laser-induced CNV. CAD was expressed in Ad-CAD-infected cells and inhibited the angiogenic activity in human umbilical vein endothelial cells in vitro.

Risk Factors for the Postoperative Transfusion of Allogeneic Blood in Orthopedics Patients With Intraoperative Blood Salvage: A Retrospective Cohort Study.

The purpose of this study is to explore the risk factors affecting the postoperative transfusion of allogeneic blood in patients undergoing orthopedics surgery with intraoperative blood salvage (IBS). A retrospective study of 279 patients undergoing orthopedic surgeries with IBS from May 2013 to May 2015 was enrolled. The binary logistic regression was used to find out the risk factors associated with postoperative transfusion of allogeneic blood in orthopedics patients with IBS, and then receiver operating characteristic (ROC) curve was drawn to determine the optimal threshold of the regression model.
