Abstract:
BACKGROUND: Parameters of platelet can reflect functions of coagulation. Granule membrane protein-140 (GMP-140), which is also called P-Selectin, in α-granules of platelets can reflect activities of platelet. Dysfunction of blood sugar and blood lipid in diabetic patients can result in complications such as thrombotic diseases.OBJECTIVE: To analyze the variation regulation of the platelet parameters and GMP-140 in patients with type 2 diabetes mellitus.DESIGN: A case-control study.SETTING:Department of Clinical Laboratory and Department of Endocrinology, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology.PARTICIPANTS: From March to April 2005, forty-five patients with type 2 diabetes mellitus, who were treated at the Department of Endocrinology,Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology, were enrolled as diabetic group, and 45 healthy people, who were checked with health examination at the same period,were selected as control group. They all joined the experiment voluntarily. METHODS: Changes of quantity of blood platelet, mean platelet volume (MPV), platelet distribution width (PDW) and platelett-large cell ratio (PLCR) were analyzed with blood cell counter. GMP-140 was measured by enzyme-linked immunosorbent assay (ELISA), meanwhile, compared with those of the healthy people.MAIN OUTCOME MEASURES: Contents of the parameters of platelets and GMP-140 of subjects in the two group s.RESULTS: A total of 90 cases without drop out, 45 cases in the diabetic group and control group, respectively, were involved in the result analysis.①Comparison of the content of GMP-140 in the two groups: It was significantly higher in the diabetic group than that in the control group [(28.8±10.3) ,(9.1±5.6)μg/L(t=2.37,P ＜ 0.01 )]. ②Comparison of parameters of blood platelet of subjects of the two groups: The MPV, PDW and P-LCR in patients of the diabetic group were markedly higher than those in the control group (t=2.02, 2.02, 2.02, P ＜ 0.01 ), while the blood platelets (PLT)was dramatically lower than that in the control group (t=2.15, P ＜ 0.01 ).CONCLUSION: The MPV, PDW, P-LCR and the content of GMP-140 of patients with type 2 diabetes mellitus significantly increase, while the PLT decreases, which indicate that platelet activity enhances and the consumption of platelet increases in patients with type 2 diabetes mellitus.
