不同糖代谢人群血尿酸、血脂及胰岛素抵抗相关性研究

Objective To study the levels of senlm uric acid(UA)in normal glucose(NC),impaired glucose regulation(IGR)and type 2 diabetes mellitus(T2DM),and investigate its relationship with insulin resistance and dyslipidemia.Method The levels of blood glucose,lipids,fasting insulin(HNS)and serum UA were measured in patients of 45 T2DM(T2DM group),20 IGR(IGR group)and 29 NC(NC group).Status of insulin resistance and insulin secretion function was evaluated by HOMA-IR and ISI.Results The levels of triglyceride(TG)and UA in T2DM group and IGR group were significantly higher than those in NC group[(3.34±8.77),(1.85±0.67),(1.26±0.38)mmoi/L and(316.71±96.20),(403.62±76.80),(325.45±94.43)mmol/L](P<0.01).HDL-C levels in T2DM group were significantly lower than those in IGR and NC group[(1.05±0.30),(1.07±0.21),(1.12±0.20)mmol/L](P<0.01).NO significant difference of FINS levels was found in the three groups.HOMA-IR level in T2DM and IGR group was higher than that in NC group(3.84,3.77,2.34)(P<0.01).ISI in T2DM and IGR group was lower than that in NC group(-4.52±0.79,-4.44±0.19,-4.03±0.58)(P<0.01).Correlation analysis indicated that the level of UA was positively related with BMI.TG and negatively related with HDL-C.Conclusion Increased UA in IGR indicates that hyperurieacidemia developes before DM.

Objective To explore the possible mechanism of sex hormone-binding globulin (SHBG) in diabetes mellitus by detecting the level of serum SHBG in patients with newly diagnosed type 2 diabetes mellitus (T2DM),and analyze the correlation between serum SHBG and insulin resistance.Methods SHBG levels were determined by enzyme linked immunosorbent assay (ELISA) in 30 normal controls (control group) and 60 newly diagnosed T2DM patients(T2DM group).HOMA-IR was calculated.Results The levels of serum SHBG in T2DM group were significantly lower than those in control group [(22.6 ±9.7)mmol/L vs.43.1 ±11.9) mmol/L,P <0.05]; SHBG level was negatively correlated with triglyceride(TG),low density hpoprotein cholesterol(LDL-C),fasting insulin(FINS),hemoglobintHbA1c) and lgHOMA-IR (r =-0.351,-0.361,-0.426,-0.645,-0.483,P <0.05),and positively correlated with high density lipoprotein cholesterol (HDL-C) (r =0.453,P <0.01).When SHBG was analyzed as a dependent variable by multiple linear regression,HbA1c (β =-0.614,P =0.000),lgHOMA-IR (β =-0.473,P = 0.014) and HDL-C (β = 0.234,P= 0.048) were into the equation.Conclusions Patients who have diagnosed T2DM show low level of serum SHBG.HOMA-IR and HbA1c are key indicators of SHBG,suggesting that SHBG may be closely related with T2DM.     

血清内脂素与儿童初诊1型糖尿病及合并酮症酸中毒患儿糖脂代谢的相关性研究

目的 通过检测1型糖尿病(T1DM)患儿及T1DM合并酮症酸中毒患儿血清内脂素(visfatin)水平,探讨血清visfatin与T1DM及酮症酸中毒患儿的糖脂代谢及胰岛β细胞功能的相关性。方法 选取2010年6月-2014年6月于广元市中心医院门诊就诊和住院的1型糖尿病患儿82例,正常对照组31例,1型糖尿病患儿分为初诊T1DM组(T1DM I组) 61例,T1DM合并酮症酸中毒组(T1DM Ⅱ组) 21 例。比较三组血清visfatin水平、空腹血糖(FPG)、空腹胰岛素(Fins)、总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、游离脂肪酸(FFA)及糖化血红蛋白(HbAlc),体质指数(BMI)及腰臀比(WHR)。并进行T1DM I组和T1DM Ⅱ组的血清visfatin与其他监测指标的单因素相关性分析,及血清visfatin与其相关因素的多元线性逐步回归分析。结果 1)儿童T1DM I组血清visfatin水平明显低于正常对照组(P<0.01),T1DM Ⅱ组血清visfatin水平较T1DM I组明显降低(P<0.01)。2)采用Pearson 相关分析,在T1DM I组和T1DM Ⅱ组中血清visfatin均与BMI、WHR、HDL-C、Fins、Homa-β呈正相关,均与TC、TG、LDL-C、FFA、FPG、HbAlc呈负相关。多元线性逐步回归分析显示,T1DM I组和 T1DM Ⅱ组的WHR、FFA、FPG、Homa-β进入回归方程,WHR、FFA、FPG、Homa-β是影响血清visfatin水平的独立危险因素。结论 1型糖尿病及合并酮症酸中毒患儿血清visfatin水平较正常组明显降低,可能与内脏脂肪含量减少,糖脂代谢紊乱及胰岛β细胞功能损害有关。     

短期胰岛素泵强化治疗对2型糖尿病患者内皮依赖性血管舒张功能的影响

目的 探讨短期胰岛素泵强化治疗对合并及不合并有大血管并发症的2型糖尿病(T2DM)患者内皮依赖性血管舒张功能(FMD)的影响.方法 选择T2DM患者76例(T2DM组),分为两个亚组,合并有大血管并发症者28例(T2DM1组),无大血管并发症者48例(T2DM2组),另选年龄、性别相匹配的健康对照者30例(NC组),所有对象均接受高频超声检测肱动脉血管FMD,T2DM组经胰岛素泵强化治疗后复查.同时检测血糖、血脂、空腹胰岛素及其他代谢指标,并计算稳态模型法胰岛素抵抗指数(HOMA-IR).结果 与NC组比较,T2DM组患者FMD显著下降(P＜0.01),而糖化血红蛋白(HbA1c)、空腹血糖(FPG)、HOMA-IR、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆同醇(LDL-C)显著增高(P＜0.01或＜0.05).相关分析显示FMD与HbAI1c、FPG、HOMA-IR、TG、LDL-C呈负相关(P＜0.01).与高密度脂蛋白胆同醇(HDL-C)呈正相关(P＜0.01).T2DM组经胰岛素泵强化治疗2周后.两个亚组患者FMD改善效果不同,T2DMl组由治疗前(4.25±1.96)%增至治疗后(4.96±1.36)%(P＞0.05),T2DM2组由治疗前(4.02±2.35)%增至治疗后(7.56±2.34)%(P＜0.01).结论 短期胰岛素泵强化治疗能明显改善不合并有大血管并发症T2DM患者的FMD.

Abstract：

Objective To investigate the effects of short term insulin pump intensive therapy on flow-mediated dilation (FMD) in type 2 diabetes mellitus (T2DM) patients with and without vascular complications. Methods Seventy-six patients with T2DM (T2DM group) were divided into 2 subgroups: T2DM1 subgroup (28 patients with vascular complications) and T2DM2 subgroup (48 patients without vascular complications). Meanwhile, 30 healthy cases were selected as NC group. All research subjects accepted high-frequency ultrasound detection on brachial artery for FMD. After insulin pump intensive therapy,FMD in T2DM group was reexamined, fasting insulin was detected and HOMA-IR was calculated. Results Compared with that in NC group, FMD in T2DM group was significantly lower(P＜ 0.01). However, glycosylated hemoglobin (HbA1c ), fasting plasma glucose (FPG ),H0MA-IR and blood fat were significantly higher (P＜0.01 or ＜0.05). Correlation analysis showed that FMD had negative correlation with HbA1c, FPG, HOMA-IR, triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C)(P＜0.01),and had positive correlation with high-density lipoprotein cholesterol (HDL-C). After 2 weeks of insulin pump therapy, the improvement of FMD between the two groups was different. FMD in T2DM1 subgroup increased from (4.25 ± 1.96)% to (4.96 ± 1.36)%(P＞0.05), and FMD in T2DM2 subgroup increased from (4.02 ± 2.35)% to (7.56 ± 2.34)%(P＜ 0.01). Conclusion Insulin pump intensive therapy can evidently improve FMD in T2DM patients without vascular complications.
