METHODS: Overall review of available literatures relating K469 E polymorphism to the risk of DR was conducted on 4 electronic databases. Meta-analysis was performed by Stata 12.0 to calculate pooled odds ratios(ORs). Potential sources of heterogeneity and bias were explored.RESULTS: Seven studies with genotype frequency data including 1120 cases with DR and 956 diabetic controls free of DR were included. Meta-analysis did not show significant association of K469 E polymorphism with DR(P 】0.05). A statistically significant association was detected between the K469 E polymorphism and proliferative DR(PDR) in Asians only in dominant model(GG+AG vs AA) with pooled OR of 0.729(95%CI: 0.564-0.942, P=0.016, P heterogeneity=0.143), however, this association was not detected in recessive model(AG +AA vs GG;OR=1.178, 95%CI: 0.898-1.545, P =0.236, P heterogeneity=0.248)or allelic model(G vs A; OR=0.769, 95% CI: 0.576-1.026,P =0.074, P heterogeneity=0.094). No publication bias was found by Funnel plot, Begg’s and Egger’s test. CONCLUSION: This research found no statistically significant association between ICAM-1 gene K469 E polymorphism and DR in patients with T2 DM, but showed significant association of the K469 E polymorphism with PDR in Asian diabetic patients only in dominant model. Further investigation would be required to consolidate the conclusion.展开更多
