波动性高血糖状态与糖尿病血管病变的关系

目的探讨2型糖尿病患者波动性高血糖状态对糖尿病慢性并发症的影响。方法169例糖化血红蛋白（HbA，c）相近2型糖尿病患者分为两组：慢性持续性高血糖组（Ⅰ组，78例）、慢性波动性高血糖组（Ⅱ组，91例）。测定患者的空腹血糖（FBG）、餐后2h血糖（2hPG）、糖化血红蛋白（HbA1c）、胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL）、低密度脂蛋白胆固醇（LDL）、空腹胰岛素（FINS）、餐后2h胰岛素（2hINS）、空腹C肽、餐后2hC肽、24h尿白蛋白定量（UAER），并分析其糖尿病慢性并发症的发生情况。结果Ⅱ组2hPG显著高于Ⅰ组（P〈0．01），餐后2h胰岛素与餐后2hC肽水平显著低于Ⅰ组（P〈0．01）。Ⅱ组糖尿病慢性并发症发生率显著高于Ⅰ组（P〈0．01）。结论2型糖尿病在波动性高血糖状态下慢性并发症明显增加。

Relationship between glucose fluctuation state and diabetic chronic complications in type 2 diabete mellitus

Objective To explore the relation between glucose fluctuation state and diabetic chronic compli-cations in type 2 diabetes mellitus. Methods 169 cases with type 2 diabetes mellitus were divided into two groups: 78 cases with constant high glucose(group Ⅰ) and 91 cases with glucose fluctuation state( group Ⅱ ). The clinical data such as fasting plasma glucose(FBG) ,fasting blood insulin(FINS) ,fasting blood C peptide,2 hours postprandial plasma glucose (2hPG) ,2 hours postprandial blood insuline (2hINS) ,2 hours postprandial blood C peptide, glycosy-lated hemoglobin A1c (HbA1c), and blood pressure (BP), body mass index ( BMI ), urinary albumin excretion rote (UAER) ,triglyeeride(TG) ,total cholesterol(TC) ,high density lipoprotein cholesterol(HDL-C) ,low density lipopro-tein cholesterol(LDL-C) were measured. Results 2hPG in group Ⅱ was much higher than that in group Ⅰ (P<0.01) ,but 2 hours postprandial blood insuline and 2 hours postprandial blood C peptide in group Ⅱ were much lower than those in group Ⅰ (P<0.01). The incidence of diabetic chronic complications was higher in group Ⅱ compared with that in group Ⅰ (P<0.01). Conclusion These findings suggest that glucose fluctuation state with type 2 dia-betes mellitus had increased diabetic chronic complications.
