Abstract:
Objective To observe the expression of FGF19 (fibroblast growth factor 19) and PEDF (pigment epithelium-derived factor) in the serum of type 2 diabetic retinopathy (DR) patients and discuss their significance.Methods Total 89 patients with type 2 diabetes were selected and divided into two groups according to whether they were combined with diabetic retinopathy:45 patients with type 2 diabetes alone (DM group) and 44 patients with type 2 diabetes mellitus combined with retinopathy (DR group).At the same time,40 healthy people were selected as the control group (NDM group).The serum levels of FGF19 and PEDF and their biochemical indexes were detected and compared in each group.The correlation between the indexes and the relationship between FGF19,PEDF and DR were analyzed.Results Compared with NDM group,serum FGF19 level in DM group and DR group decreased,while C-reactive protein (CRP) and PEDF level in DM group and DR group increased (P ＜ 0.05);serum FGF19 level in DR group was lower than that inDMgroup,while serum PEDF level was higher than that in DM group (P ＜0.05).The levels of fasting blood glucose (FBG),fasting insulin levels (FINS),glycosylated hemoglobin (HbA1c),total cholesterol (TC),high density lipoprotein (HDL) and low density lipoprotein (LDL) in DM and DR groups were higher than those in NDM group (P ＜ 0.05),but there was no significant difference between DM group and DR group (P ＞ 0.05);the levels of Hcy,triacylglycerol (TG) and CRP in DR group were higher than those in DM and NDM group (P ＜ 0.05),and the levels of VLDL were lower than those in DM and NDM group (P ＜ 0.05).The level of serum FGF19 was positively correlated with HDL and CRP in patients with DR (r =0.341,0.623,P ＜ 0.05),and negatively correlated with fasting blood glucose(r =-0.428,P ＜0.05);The level of serum PEDF in patients with DR were negatively correlated with FINS (r =-0.343,P ＜0.05).When the serum level of PEDF ＞ 12.76 mg/L,the sensitivity and specificity of PEDF dignosing DR were 80.9％ and 56.7％ respectively.Conclusions In patients with DR,serum FGF19 level decreased and serum PEDF levels increased.The level of both changes is closely related to DR and may be involved in the development of DR.
