Abstract:
Objective To investigate the correlation between postmenopausal estrogen levels and diabetic retinopathy in patients with type 2 diabetes.Methods Two hundred cases of postmenopausal type 2 diabetes admitted to the Eighth Affiliated Hospital,Sun Yat-sen University from January 2015 to January 2017 were selected as the subjects and divided into the retinopathy group (93 cases) and the normal retina group (107 cases) according to the resuhs of fundus angiography.The general data of the two groups were compared,and the blood glucose index,blood lipid index and estrogen level were measured and compared.Logistic regression analysis was used to analyze the related factors of the patients with retinopathy.Results (1) The disease duration of patients in the retinopathy group was longer than that in the normal retina group ((14.67 ±3.48) years vs.(10.20±2.85) years;t=9.983,P＜0.05).The fasting blood glucose (FBG),glycosylated hemoglobin of patients in the retinopathy group were higher than those in the normal retina group (FBG:(8.01 ± 1.21) mmol/L vs.(6.93 ± 1.20) mmol/L,FBG:(8.32 ± 1.56) mmol/L vs.(7.39 ± 1.43) mmol/L;t =6.324,4.397,P＜0.05).The total cholesterol (TC),triglyceride (TG) and low density lipoprotein (LDL-C) of patients in the retinopathy group were higher than those in the normal retina group [TC:(4.93±0.87) mmol/ Lvs.(4.23± 0.69) mmol/L,TG:(1.91 ± 0.42) mmol/L vs.(1.63 ± 0.32) mmol/L,LDL-C:(2.61 ± 0.90) mmol/L vs.(1.78±0.53) mmol/L;t =6.340,5.340,8.067,P＜0.05],while high density lipoprotein (HDL-C) was lower than that in the normal retina group ((1.23±0.37) mmol/L vs.(1.76±0.45) mmol/L;t =9.014,P ＜0.05).The E2 level in the retinopathy group was lower than that in the normal retina group ((23.91 + 8.51) ng/L vs.(32.18 + 9.80) ng/L;t=6.325,P＜0.05).Logistic regression analysis showed that the duration of diabetes,FBG,HbAlc,TC,TG and LDL-C were risk factors of retinopathy (OR (95％ CI) =1.049 (1.011 ～ 1.056),1.071(1.061 ～ 1.093),1.092(0.984～ 1.275),1.099(1.661 ～ 1.993),1.863(1.661 ～ 1.993),1.652 (1.461 ～ 1.893),P＜ 0.05),while HDL-C and E2 were protective factors of retinopathy (OR (95 ％ CI) =0.172(0.061 ～ 0.293),0.955 (0.861 ～ 1.093),P＜0.0S).Conclusion Estrogen level is related to retinopathy in postmenopausal diabetic patients.It may be a protective factor for diabetic retinopathy.
