Résumé
Objective To investigate the relationship between the relevant platelet parameters and the thromboelastographic in-dexes with the the occurrence and development of diabetic vascular complications so as to early find the high-risk group of vascular complications or early patients .Methods According to the WHO diagnostic criteria for diabetes ,268 patients with diabetes and 80 retired people with the physical examination (normal control group) were selected as the research subjects .268 cases were divided into the group A(HbA1c 6 .5% without vascular complications) and the group C(HbA1c >8 .0% with vascular complications ) .The Siemens ADVIA2120 fully automatic blood analyzer was adopt-ed to detect the platelet parameters of mean platelet volume (MPV) ,platelet distribution width(PDW) ,large-platelet(L-PLT) , MPM and mean platelet concentration(MPC);The TEG@ 5000 coagulation analyzer was adopted to perform the thromboelastogra-phy for detecting the values of R ,K ,Angle A and MA .All obtained data were statistically analyzed .Results L-PLT in the group B and the platelet parameters in the group C had statistical differences compared with the normal control group (P<0 .05) .The val-ues of R ,K ,Angle A in the group B and the values of R ,K ,Angle A and Ma in the group C had statistical differences compared with the normal control group (P<0 .05) .Conclusion Relevant platelet parameters and the thrombelastogram detection have the important significance to help to the clinical diagnosis of diabetic angiopathy ,guide the treatment and the condition monitoring ;the thrombelastogram is more sensitive than the detection of the relevant platelet parameters in early finding the patients with diabetic angiopathy .
