Abstract:

Objective

To discuss the relationship among high molecular weight adiponectin (HMW-ADP), tumor necrosis factor(TNF)-α and vascular endothelial growth factor(VEGF) with diabetic retinopathy(DR).

Methods

150 cases with type 2 diabetes mellitus from January to December 2014 were selected as study objects, 50 cases with NDR, 50 cases with NPDR and 50 cases with PDR. 50 cases for physical examination were selected as control group. Compared with the gender, history of hypertension and diabetes family history of χ2test. The clinical data such as HMW-ADP, TNF-α, VEGF, biochemical indexes and body mass index were all expressed by mean and standard deviation (±s), and compared by single factor analysis of variance. The effects of HMW-ADP, TNF-α, VEGF and other factors on NPDR and PDR were analyzed by multiple Logistic regression. The correlation of HMW-ADP, TNF-α and VEGF with DR was analyzed by Pearson correlation.

Results

The age of the NPDR group and the PDR group were larger than that of the NDR group and the control group (F=5.329, P<0.05). The history of hypertension in group NDR, group NPDR and group PDR were significantly higher than that of control group (χ2=20.215, P<0.05). The patients in group PDR had the longest course, followed by group NPDR, and the group NDR was the shortest (F=96.434, P<0.05). Fasting blood glucose in patients in group NDR, group NPDR and group PDR were significantly higher than that of control group (F=12.510, P<0.05). The fasting insulin levels in group PDR were the highest, followed by group NPDR and group NDR, and lowest in the control group (F=25.305, P<0.05). The content of triglyceride (TG) in patients in group NDR, group NPDR and group PDR were significantly higher than that of control group (F=16.419, P<0.05). The content of high-density lipoprotein cholesterol (HDL-C) was significantly lower than that of the control group (F=4.259, P<0.05). The creatinine of group NPDR and group PDR was significantly higher than that of control group (F=47.158, P<0.05). The difference between the two groups was statistically significant. The level of HMW-ADP in the NPDR group and the PDR group were significantly lower than that in the control group and the NDR group, and the NDR group was significantly lower than that of the control group, the difference between the two groups was statistically significant (F=362.480, P<0.05). The levels of TNF-α and VEGF in group PDR were the highest, followed by NPDR group; NDR group and control group were lowest, the difference between the two groups were statistically significant (F=239.200, 641.970; P<0.05). Multivariate analysis showed that age, duration of disease, TNF-α and VEGF were independent risk factors for NPDR (χ2=7.621, 18.331, 5.532, 5.618; P<0.05), and they were also independent risk factors for PDR (χ2=6.962, 11.542, 5.615, 5.331; P<0.05). HDL-C and HMW-ADP were protective factors for NPDR (χ2=6.694, 10.671; P<0.05), and they were also protective factors for PDR (χ2=5.674, 7.671; P<0.05). The levels of HMW-ADP in patients with DR were negatively correlated with TNF-α and VEGF (r=-0.328, -0.810; P<0.05).

Conclusion

In patients with DR, the level of HMW-ADP decreases, and the levels of TNF-α and VEGF increase; Multivariate analysis shows that HMW-ADP is protective factor, and TNF-α and VEGF are risk factor; HMW-ADP is negatively correlated with TNF-α and VEGF.
