Conclusions:HbA<sub>1c</sub> is a practical and convenient tool for screening undiagnosed diabetes in routine health check-up of a large population.Combined use of HbA<sub>1c</sub>≥6.3%and/or FPG≥7.0 mmol/L is efficient for early detection of diabetes.展开更多

Methodology: 108 medical records of patients with type 2 diabetes mellitus were evaluated. We obtained averages of: blood glucose (162.3 ± 73.10 mg/dl), glycated hemoglobin (HbA1c = 7.64% ± 1.77%), cholesterol (189.28 ± 35.25 mg/dl), triglycerides (189.11 ± 87.76 mg/dl), Systolic Blood Pressure (SBP = 119.69 ± 14.95 mmHg), Diastolic Blood Pressure (DBP = 77.15 ± 9.55 mmHg) and Media Blood Pressure (MBP = 91.36 ± 9.89 mmHg). We correlated variable HbA1c with vascular injury symptomatology. Results: Correlation was found between sensitivity dysfunction and HbA1c with a statistical significance of p = 0.01, and a correlation Kendal coefficient w = 0.01, any other parameter of metabolic control was not correlated with symptoms of vascular injury. Conclusion: It is remarkable that the sensitivity dysfunction is a symptom of poorly vascularized lower extremities caused for both functional impairment and structural changes in diabetic patients’ peripheral nerves, even in the preclinical stage of vascular disease. The HbA1c could also be investigated as a likely sensitivity dysfunction biomarker in DM due to the correlation presented in this study but more studies must be realized.展开更多

With the increased level of HbA<sub>1c</sub>,TC/HDL-C,LDL-C/HDL-C ratios were gradually increased, with significant differences among groups（P【0.05）.The lipid ratios,especially LDL-C/HDL-C ratio was more susceptible to impaired lipid metabolism in T2DM patients than individual lipid. Conclusions:LDL-C/HDL-C ratio is helpful in assessing and reducing the risk of cardiovascular disease caused by impaired lipid metabolism in type 2 diabetic patients.展开更多
