Objective To explore the clinical features of diabetic macular edema (DME) with optical coherence tomography (OCT) and correlation with visual function. Methods Forty-nine eyes from 40 patients with DME (DME group) and 31 eyes from 31 patients without DME (control group) were examined with OCT,pattern reversal visual evoked potentials (P-VEP),macular perimetry. According to proliferative diabetic retinopathy (PDR), 49 eyes with DME were divided into group A (without PDR, 30eyes) and group B (with PDR, 19 eyes). Results The retinal macular thickness of central fovea in DME group [(299.25±63.87)μm] was more than that in contol group [(204.35 ± 37.94)μm], visual acuity and macular visual field in DME group were significantly different than those in control group, respectively (P ＜ 0.05). The retinal macular thickness of central fovea,visual acuity and visual field were no significant differences between group A and group B (P＞0.05). OCT macular thickness and visual correlation coefficient was -0.437(P＜ 0.05 ); OCT macular thickness and mean defect correlation coefficient was 0.441(P ＜ 0.05). Conclusions OCT can provide a useful tool for monitoring the occurrence and development of DME, can assess the response to treatment. With increasing of the macular retinal thickness, the visual acuity and macular visual field of visual function are more damaged.

OBJECTIVE: To study ApoB gene genetic polymorphism of Han nationality and Mongolian nationality in midwest area of Inner Mongolia. METHODS: Some unrelated individuals of Han nationality and Mongolian nationality in midwest area of Inner Mongolia were selected. Polymerase chain reaction-restriction fragment length polymorphism technology was used to check the presence of Xba I (X+) and EcoR I (E-) sites of rare alleles. The genotype frequency, allelic frequency and population genetics parameters were calculated. RESULTS: The frequencies of Xba I (X+) and EcoR I (E-) rare alleles were 2% and 4.6% in Han population. There was no Xba I (X+) or EcoR I (E-) rare alleles found in Mongolian nationality. CONCLUSION The allelic frequencies of ApoB gene Xba I and EcoR I sites are very different in different races. These sites may be used in identification of ethnicity.
