Objective To investigate the level of adenosine in vitreum and the expression of CD73 in proliferative membrane in patients with proliferative diabetic retinopathy (PDR). Methods Thirty patients underwent vitrectomy in the Ophthalmology at Daping Hospital were divided into two groups
including a PDR group (n=16) and a control group (n=14). Rhegmatogenous retinal detachment
idiopathic macular hole and macular epiret
inal membrane were included in the control group. The level of adenosine in vitreum was measured by HPLC
and the expression of CD73 in preretinal membranes was measured by Western blotting. Results The level of adenosine in the PDR group was significantly higher than that in the control group [(62.37±11.47)μmol/L vs (30.34±6.41)μmol/L,
P
=0.000
]
. The expression of CD73 in the PDR group was significantly higher than that in the control group (0.84±0.08 vs 0.39±0.05
P
=0.002). There was no correlation with age
course of diabetes and fasting plasma glucose in the PDR patients and the concentration of adenosine in vitreum before operation (r=0.255
P
=0.340; r=0.318
P
=0.230; r=0.341
P
=0.197). Conclusion Adenosine and CD73 may be involved in the progress of neovascularization in PDR.
