Abstract
Objective To explore the relationship between platelet activating factors and four platelet parameters in diabetic retinopathy (DR).Methods Eighty patients in our hospital were chosen from January 2015 to December 2015,regular ophthalmological examination and fundus fluorescence were performed on all cases.On the basis of international clinical diabetic retinopathy classification standard,the patients were divided into four groups:No DR group with 20 cases,non-proliferative diabetic retinopathy (NPDR) group with 20 cases,and proliferative diabetic retinopathy (PDR) group with 20 cases.20 healthy people who received physical examination during the same period were recruited as the control group.The flow cytometry instrument was used to determinate platelet activating factor CD62p and CD63,automatic blood analyzer was used to determinate platelet parameter which including blood platelet count (PLT),mean platelet volume (MPV),plateletcrit (PCT) and platelet distribution width (PDW),and the changes of platelet activation factor,parameters and its clinical significance in DR were discussed.Results With the development of DR,CD62p,CD63,MVP were numerical gradually increased,and PLT were numerical gradually reduced,the differences were statistically significant (all P ＜ 0.05);Compared with control group,CD62p,CD63,MVP were increased and PLT were reduced in other group,the differences were statistically significant (all P ＜ 0.05);Compared with pure diabetes group,CD62p,CD63,MVP were increased and PLT were reduced in NPDR group and PDR group,the differences were statistically significant (all P ＜ 0.05);Compared with NPDR group,CD62p,CD63,MVP were increased and PLT were reduced in PDR group,the differences were statistically significant(all P ＜ 0.05).PDW were numerical gradually increased in control group,pure diabetes group,NPDR group,PDR group,the differences were statistically significant(all P ＜ 0.05);Control group compared with pure diabetes group,NPDR group compared with PDR group,the differences in PDW was not statistical significant (all P ＞ 0.05);But compared with control group or pure diabetes group,PDW of NPDR group and PDR group increased,the differences were statistically significant(all P ＜ 0.05).The differences in PCT among groups was not statistically significant(all P ＞ 0.05).Conclusion The platelet activating factor CD62p,CD63 and parameters of platelet show differences in each diabetic retinopathy period,platelet activating factor in the occurrence and development of diabetic retinopathy have important significance.Monitor the platelet activating factor and parameters of platelet can help surveillance of the disease.关键词
