Objective:Immune cells and inflammatory mediators play important roles in the development of atherosclerotic vascular inflammation.This study focuses on the direct effect ofIL-27 on human coronary artery endothelial cells.Methods:In this study,the effects of IL-27 and TNF-α on inflammatory cytokines and chemokines were investigated.Results:IL-27 could significantly enhance the TNF-α-mediated upregulation of inflammatory cytokine IL-6 and chemokines CCL5 from human coronary artery endothelial cells.The release of IL-6 and CCL5 was significantly suppressed by specific signaling molecule inhibitors.Conclusion:The induction of these mediators from the human coronary artery endothelial cells could be differentially regulated by the c-Jun N-terminal kinase,p38 mitogen-activated protein kinase,and nuclear factor-κB pathways.These results provided new insights into the effect of IL-27 on the TNF-α mediated activation of human coronary artery endothelial cells in atherosclerotic vascular inflammation.

Objective To propose SHA.LIN nephrolithometry scoring system for assessing and predicting the stone-free rate of percutaneous nephrolithotomy ( PCNL) and to investigate the clinical value of SHA.LIN scoring system for nephrolithiasis in patients undergoing PCNL .Methods A literature review from 1976 to 2014 was performed to identify clinically relevant and reproducible variables that could affect the outcomes of PCNL. Six reproducible variables available from preoperative noncontrast-enhanced computed tomography were measured , including stone size ( S) , hydronephrosis ( H) , anatomic distribution (A), length of tract(L), indicator of CT(I), number of involved calices(N) and was named as SHA.LIN nephrolithometry scoring system .A retrospective analysis was conducted of clinical data of 116 patients with nephrolithiasis undergoing PCNL from June 2011 to March 2015. The general conditions , preoperative information , stone characteristics and perioperative variables were collected . The correlation of nephrolithometry scores based on SHA.LIN scoring system with stone-free status, operation time, blood loss, length of hospital stay and postoperative complications were analyzed . Receiver operating characteristic ( ROC) curves was drawn to detect sensitivity and specificity of SHA .LIN score in predicting the stone-free rates of PCNL.Results The SHA.LIN score was 9.13 ±2.24 in this cohort.The stone free rate was 75.9%(88/116).Postoperative complications occurred in 32 (27.6%) cases.In those patients with stone
free, the SHA.LIN score was 8.27 ±1.62, significantly lower than that in those patients with residual stones 11.86 ±1.72 ( t =-10.069, P=0.000) .The SHA.LIN score showed significant correlation with the postoperative stone free status, operation time, estimated blood loss (P<0.01).But, it did not correlate with postoperative complications and length of hospital stay (P>0.05).The area under curve of ROC curves for the SHA.LIN scoring system was 0.923 ( 95%CI 0.870 -0.975 ) . Conclusions The SHA.LIN nephrolithometry scoring system can predict postoperative stone-free status of PCNL and can be used for disease related assessment.Further research is required to evaluate its performance in predicting peri-operative variables and postoperative complications .
