ABSTRACT
Objective To study the relationship between glycemic control and platelet parameters in newly diagnosed type 2 diabetic patients. Methods Ninety patients newly diagnosed as type 2 diabetes and 90 healthy people were enrolled into the study. Their blood pressure, platelet parameters, including blood platelets count (PLT), mean platelet volume (MPV), platelet distribution width (PDW), fasting blood glucose (FPG),HbA1c ,triglyceride ( TG ), total cholesterol ( TC ), high density lipoprotein cholesterol (HDL-C ), low density lipoprotein cholesterol(LDL-C) were examined and the data were analyzed. Results The level of FBG, TG, TC,MPV and PDW of patients newly diagnosed as type 2 diabetic were significantly higher than those of healthy people (t =6. 405,2. 069,2. 633,2. 178,2. 103 ;P =0. 001,0. 046,0. 010,0. 031 and 0. 043 respectively); The level of FBG, HbA1c, TC, TG, MPV and PDW in the diabetic patients, with their HbA1 c ＞ 7%, were significantly higher than the patients with HbA1c ≤ 7 % ( t = 5.691,2.013,2. 345,3. 467,4. 016,2. 893, P = 0. 001, 0. 038,0. 029,0. 013, 0. 004, 0. 026 ). There were positive correlations between MPV and HbA1c ( r = 0. 389 P =0. 020), MPV and PDW ( r = 0. 324 P = 0. 01 ) in diabetic patients, but no correlation between MPV and FBG,MPV and Systolic BP or MPV and Diastolic BP (Ps ＞ 0. 05 ). The level of FBG, HbA1c, TG, MPV and PDW decreased significantly in the diabetic patients with HbA1c ＞ 7% after treatment (t = 5. 591,2. 301,2. 410,2.204,2.105; P=0.001,0.031,0.023,0.035,0.041, respectively).Conclusion The platelet activity enhanced in newly diagnosed type 2 diabetic patients, platelet activity can be recovered through glycemic control,which may prevent the role of platelet in diabetes complications in these patients.
ABSTRACT
Objective To investigate the effect of Chlorogenic acid on oxidative and antioxidative system of kidney in diabetic rats.Methods 36 rats were randomly divided into three groups:normal group(N group),diabetes mellitus group(DM group)and diabetes group treated with chlorogenic acid(CA group).Ten weeks later,blood glu-cose,weight of body and kidney ,the activity of superoxide dismutase(SOD)and glutathione peroxidase(GSH-PX)lipidperoxidation(MDA),urinary albumin excretory rate(UARE)in renal tissue were measured.Results The levels of blood glucose were not significantly different between DM group and CA group,but the weight of rats and kid-ney and the activity of SOD and GSH-PX in CA group were higher than DM group,and MDA and UAER of CA group were lower(P<0.05 for each).Conclusion Chlorogenic acid effective in improving the antioxidativity,inhibiting oxidative stress and decreasing urinary albumin.
