[摘要] 目的 觀察新诊断2型糖尿病(T2DM)患者血清谷氧还蛋白(Grx)水平与胰岛素抵抗的相关性。 方法 选择2016年1~5月在河北省唐山市人民医院(以下简称“我院”)内分泌科就诊的新诊断T2DM患者90例作为T2DM组,同时从我院健康体检中心选取非糖尿病健康人群70例作为正常组。观察两组年龄、性别、体重指数(BMI)、收缩压(SBP)、舒张压(DBP),收集其临床检验结果,包括空腹血糖(FPG)、糖化血红蛋白(HbA1C)、总胆固醇(TC)、三酰甘油(TG)、高密度脂蛋白(HDL)、低密度脂蛋白(LDL)、空腹胰岛素(FINS)、谷氧还蛋白(Grx)等,计算胰岛素抵抗指数(HOMA-IR)。 结果 两组FPG、HbA1c、HOMA-IR、FINS、Grx比较,差异有统计学意义(P < 0.05)。两组年龄、性别、BMI、SBP、DBP、TC、TG、HDL、LDL比较,差异无统计学意义(P > 0.05)。相关性分析发现,Grx与HbA1c(r=0.607,P=0.007)、FINS(r=0.129,P=0.012)、HOMA-IR(r=0.189,P=0.020)呈正相关;多元线性逐步回归分析显示,Grx与HbA1c(b=1.979,P=0.000)、FINS(b=0.805,P=0.018)、HOMA-IR(b=0.783,P=0.022)呈正相关。 结论 血清Grx表达水平升高可能与拮抗导致胰岛素抵抗的因素、HbA1c有关。Grx表达水平升高可能与胰岛素抵抗、T2DM的发生和发展有关。

[Abstract] Objective To investigate the relationship between serum glutaredoxin (Grx) level and insulin resistance in newly diagnosed patients with type 2 diabetes mellitus (T2DM). Methods 90 newly diagnosed patients with T2DM in Department of Endocrinology, People′s Hospital of Tangshan City, Hebei Province ("our hospital" for short) from January to May 2016 were selected as T2DM group. 70 healthy subjects in Health Examination Center of our hospital were selected as normal group. Age, sex, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP) were observed in two groups. Clinical test results were collected, including fasting blood glucose (FPG), glycosylated hemoglobin (HbA1C), total cholesterol (TC), three glycerol (TG), high density lipoprotein (HDL), low density lipoprotein (LDL), fasting insulin (FINS), Grx. Insulin resistance index (HOMA-IR) was calculated. Results FPG, HbA1c, HOMA-IR, FINS, Grx in two groups were compared, with statistical differences (P < 0.05). Age, sex, BMI, SBP, DBP, TC, TG, HDL, LDL in two groups were compared, with no statistical difference (P > 0.05). Correlation analysis revealed, Grx was positively correlated with HbA1c (r=0.607, P=0.007), FINS (r=0.129, P=0.012), HOMA-IR (r=0.189, P=0.020). Multiple linear stepwise regression analysis showed, Grx was positively correlated with HbA1c (b=1.979, P=0.000), FINS (b=0.805, P=0.018), HOMA-IR (b=0.783, P=0.022). Conclusion The increase of serum Grx expression may be related to antagonistic factor of insulin resistance and HbA1c. The increased expression of Grx may be related to the occurrence and development of insulin resistance and T2DM.

糖尿病发病率逐年升高,然而发病机制尚不明确。研究表明,胰岛素抵抗参与2型糖尿病(T2DM)整个过程[1]。氧化应激在糖尿病发生、发展中有重要作用[2-4],也是其胰岛功能受损的重要环节[5]。谷氧还蛋白(Grx)是体内重要的抗氧化蛋白,参与了细胞氧化还原状态的调节以及机体的氧化应激过程[6]。既往有研究显示,血清25-羟维生素D3、维生素D水平与糖尿病及胰岛素抵抗有关[7-10]。也有研究证实,硫氧还蛋白(Trx)在糖尿病患者胰岛功能损伤中有重要作用,而关于Grx与胰岛素功能之间的关系国内很少报道。……
