Age-related macular degeneration (AMD) is a major cause of progressive and degenerative visual impairment. Although the exact pathogenic mechanism of AMD is still unknown, clinical observations such as the high accumulation of oxidative products and macrophages in retina suggest the importance of oxidative stress and inflammation in AMD.Mouse photoreceptor-derived 661W cells and human ARPE-19 cells were treated with oxidized phospholipids (Ox-PC) or HOxidative damage by both HThe results indicated that oxidative damage increases intracellular Ox-PC and the secretion of MCP-1 in retina cells. The increased MCP-1 induced by oxidative damage attracts macrophages to retinas, and macrophages release pro-inflammatory factor and promote the process of AMD.

Coronary artery disease (CAD) is the leading cause of death worldwide. Microarray analysis is a practical approach to study gene transcription changes that may reflect signatures that underlie the pathogenesis of CAD. Using gene expression profile data from the Gene Expression Omnibus database, we identified differentially expressed genes that can contribute to the pathology of CAD. Further pathway and network analyses were also implemented to identify pathways and hub genes related to the disease. We observed 466 downregulated and 560 upregulated genes. The ribosome pathway was the most significantly over-represented pathway with differentially expressed genes. Over 35% of the genes in this pathway were downregulated. Hub genes in the network, such as IL7R, FYN, CALM1 ESR1 and PLCG1, may play crucial roles in the pathogenesis of CAD. Our results facilitate the identification of molecular mechanisms that underlie CAD.

Objective To systematically review the risk factors in elderly patients with primary hypertension with morning blood pressure surge in China, so asto provide references for clinical treatment and prevention of complications. Methods Such databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CNKI, VIP and WanFang Data were electronically searched for the case-control studies about morning blood pressure surge (MBPS) among elderly patients with primary hypertension in China from January 2006 to June 2014 were collected. Literature was screened according to inclusion and exclusion criteria, data were extracted and the methodological quality of the included studies was assessed, and then meta-analysis was conducted using RevMan 5.2 software. Results A total of 16 studies involving 2 007 cases were finally included, of which 956 cases were detected with MBPS. The results of meta-analysis showed that significant differences were found in glucose levels (MD=0.42, 95%CI 0.04 to 0.81, P=0.03), urinary microalbumin levels (MD=23.85, 95%CI 6.64 to 41.07, P=0.007), incidences of cerebrovascular events (OR=1.96, 95%CI 1.25 to 3.08, P=0.004), carotid atherosclerosis (OR=5.13, 95%CI 1.70 to 15.45, P=0.004) and left ventricular hypertrophy (OR=2.49, 95%CI 1.70 to 3.64, P<0.000 01), left ventricular mass (MD=12.89, 95%CI 3.94 to 21.84, P=0.005), and carotid artery intima-media thickness (MD=0.08, 95%CI 0.02 to 0.14, P=0.009); while no significant difference was found in gender (OR=1.12, 95%CI 0.84 to 1.49, P=0.44), total cholesterol levels (MD=0.01, 95%CI –0.11 to 0.12, P=0.92), and creatinine levels (MD=1.77, 95%CI –1.16 to 4.70, P=0.24) between patients with or without MBPS. Conclusion Current evidence shows that glucose levels, early kidney damage, emergent cerebrovascular events and the reconstruction of the artery and the left ventricle are risk factors of abnormal MBPS in China. However, the above conclusion needs to be verified by further conducting high quality prospective studies. © 2014 Editorial Board of Chin J Evid-based Med.
