STZ诱导的糖尿病大鼠血清脂联素水平分析   总被引:2,自引:1,他引:1  
目的 探讨STZ诱导的糖尿病大鼠血清脂联素浓度及其与糖尿病肾病的关系.方法 以链脲佐菌素诱导建立1型糖尿病大鼠模型,ELISA方法测定正常对照组(A组),1型糖尿病大鼠2周(B组),6周(C组),12周(D组)及治疗组(E组)的血清和尿脂联素浓度.结果 D组和C组较A组和B组血清和尿脂联素水平均升高(均P<0.01);D组较C组血清和尿脂联素水平升高(P<0.05).E组从6~12周经胰岛素治疗后,较D组血清和尿脂联素水平有所下降(P<0.05).在C组和D组血清脂联素与24h尿白蛋白排泄率,尿脂联素呈正相关(r=0.85,P<0.01;r=0.65,P<0.01).尿脂联素与尿白蛋白排泄率呈显著正相关(r=0.78,P<0.01).逐步回归分析提示血清脂联素受尿白蛋白排泄率影响最大(β=0.89,P<0.01).结论 在糖尿病肾病发生发展中,血清脂联素水平随尿白蛋白排泄率增加而升高,补充胰岛素后血清脂联素水平下降,因此,血清脂联素水平升高是机体的一种保护机制.  相似文献

目的:探讨非胰岛素依赖型糖尿病患者血清镁水平和处发以及明显糖尿病肾病的关系.方法:以2型糖尿病患者为研究对象,根据尿白蛋白排泄值分为3组:无蛋白尿组,尿白蛋白排泄值<30 mg/d;微量白蛋白尿组,30 mg/d<尿白蛋白排泄值<300 mg/d;临床蛋白尿组,尿白蛋白排泄值>300 mg/d.并以同期健康成人16例作为对照组.检测身高、体重、血压、空腹血糖、 血清肌酐、胆固醇、甘油三酯、糖化血红蛋白、血清镁及尿白蛋白排泄值.并对数据进行统计学分析.结果:根据尿白蛋白排泄值,共有22例患者进入无白蛋白尿组;22例进入微量白蛋白尿组;20例进入临床蛋白尿组.与正常对照组比较,糖尿病患者的血清镁水平明显降低,并随着白蛋白尿程度的加重而更加明显.同时,空腹血糖、糖化血红蛋白及甘油三酯水平随着白蛋白尿程度的加重而明显升高.相关分析显示,对于出现糖尿病肾病的患者,血清镁水平与糖化血红蛋白及甘油三酯水平呈明显负相关,多元线性回归分析显示,血清镁的降低与糖化血红蛋白及甘油三酯的升高有密切关系.结论:2型糖尿病患者存在明显的低镁血症,并且随着糖尿病肾病的加重而明显降低.出现低镁血症的原因可能是血糖控制不理想及白蛋白尿对肾小管的持续损害所致.  相似文献

Objective To detect the serum microRNA-148b-3p level in patients with diabetes mellitus and diabetic nephropathy, and to analyze its correlation with clinical and pathological indexes. Methods The research crowd was divided into three groups (1) diabetic nephropathy group: biopsy with diabetic nephropathy (n=25, 14 males, 11 females); (2) type 2 diabetes mellitus group: type 2 diabetes mellitus patients with normal urinary microalbumin /urinary creatinine value (n=10, 4 males, 6 females); (3) normal control group: healthy subjects (n=9, 3 males and 6 females). Clinical indicators included gender, age, 24-hour urine protein, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine (Scr), urea (Urea), cystatin-C (Cys-C), blood albumin (ALB), urine microalbumin (UMA), triacylglycerol (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), serum uric acid (UA), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), urine microalbuminuria / urinary creatinine (UACR), and estimated glomerular filtration rate (eGFR) calculated by CKD-EPI formula. Real-time quantitative PCR was applied to verify the expression of microRNA-148b-3p in serum samples of the research crowds. The relationships between microRNA-148b-3p level and clinical features was also analyzed. Results The levels of serum microRNA-148b-3p in diabetic nephropathy group and in type 2 diabetes mellitus group were 1.82 times and 1.73 times of that in normal control group (P<0.05, respectively). The level of serum microRNA-148b-3p was significantly correlated with HDL-C (r=-0.374, P=0.013), UMA (r=0.426, P=0.004), FBG (r=0.330, P=0.046) and TG (r=0.423, P=0.005). Multiple linear regression analysis showed that UMA level was independently associated with serum microRNA-148b-3p level (β=0.338, P=0.044). The area under the receiver operating characteristic curve (ROC) of serum microRNA-148b-3p in diagnosing type 2 diabetes mellitus and diabetic nephropathy was 0.835 and 0.665, respectively. Conclusions The level of serum microRNA-148b-3p of patients with type 2 diabetes mellitus or diabetic nephropathy significantly increases. The level of UMA is independently associated with serum microRNA-148b-3p level. Serum microRNA-148b-3p is expected to be a potential biomarker for the diagnosis of diabetic nephropathy.  相似文献

BACKGROUND/AIMS: The association between microalbuminuria and magnesium depletion is a controversial issue, and serum ionized magnesium levels have not been previously studied in patients with different grades of diabetic nephropathy. Therefore, the aim of this study was to evaluate circulating ionized magnesium concentrations in patients with non-insulin-dependent diabetes mellitus (NIDDM) and incipient or overt diabetic nephropathy. METHODS: We measured fasting plasma glucose, creatinine, creatinine clearance estimate, total cholesterol and triglycerides, and serum ionized magnesium (ion-selective electrodes, ISE) in 30 NIDDM patients with urinary albumin excretion rate (UAER) <20 microg/min (normoalbuminuria), 30 NIDDM patients with microalbuminuria (20 < UAER < 200 microg/min), 30 NIDDM patients with clinical proteinuria (UAER >200 microg/min), and 20 healthy subjects. RESULTS: Serum ionized magnesium levels were significantly reduced in diabetic patients when compared to control subjects (0.39 +/- 0.06 vs. 0.58 +/- 0.05 mmol/l, p < 0.001). Moreover, diabetic patients with microalbuminuria or clinical proteinuria showed a significant decrease in serum ionized magnesium with respect to normoalbuminuria group (normoalbuminuria: 0.45 +/- 0. 02 mmol/l; microalbuminuria: 0.36 +/- 0.05 mmol/l, p < 0.001; clinical proteinuria: 0.35 +/- 0.04 mmol/l, p < 0.001). Serum ionized magnesium showed a significant negative correlation with plasma HbA1c and triglycerides in both microalbuminuria and clinical proteinuria groups. Multiple linear regression analysis showed that circulating ionized magnesium levels decrease together with the increase of plasma HbA1c and triglycerides in NIDDM patients with incipient or overt nephropathy, also after adjusting for age, sex, BMI, diabetes duration, systolic and diastolic blood pressure, hypoglycemic therapy, plasma creatinine, creatinine clearance, plasma cholesterol and fasting glucose. CONCLUSIONS: Microalbuminuria and clinical proteinuria, as well as poor glycometabolic control and hypertriglyceridemia, are associated to relevant alterations in magnesium metabolism, and the measurement of serum ionized magnesium seems to represent a useful biochemical tool for the study of magnesium disturbances in patients with different grades of diabetic nephropathy.  相似文献

Objective To investigate association between serum uric acid (SUA), albuminuria and glomerular filtration rates (eGFR) in type 2 diabetic patients. Methods A total of 220 patients were enrolled in this cross-sectional study. According to urinary albumin excretion rates, patients were divided into 3 groups: normoalbuminuria (NAU) group, microalbuminuria (MAU) group, and macroalbumnuria group (MAAU). The first two groups were subdivided at SUA>420 μmol/L (>357 μmol/L, female) into normouricemia group and hyperuricemia group, at eGFR>90 ml/min into high and low renal function groups. General information, blood biochemical results were collected to analyze the association between serum uric acid, eGFR, UAER and urine albumin quantification among different groups. Results The difference of SBP, duration of diabetes (DD), Scr, SUA and eGFR between every two groups were significant (P<0.05). SBP, DD, Scr and SUA were highest in subjects with macroalbumnuria, second in microalbuminuria group, and lowest in normoalbuminuria group, while eGFR was lowest in macroalbumnuria group and highest in normoalbuminuria group. Prevalence of hyperuricemia in macroalbumnuria group (56.9%) and microalbuminuria group (51.2%) were also significantly higher than that in normoalbuminuria group (17.5%) (all P<0.01). The difference of UAER in the subgroups of normouricemia and hyperuricemia was more significant in microalbuminuria group than in normoalbuminuria group. eGFR was significantly lower in hyperuricemia subgroups (P<0.01). Age and SUA were significantlg higher in subjects with low renal function compared with high eGFR (P<0.05). Linear regression analysis indicated SUA was negatively correlated with eGFR after adjusted age, DD and UAER (β=-0.430, P<0.01). Binary logistic regression analysis found that increased age, DD and SUA were risk factors of microalbuminuria [β=1.092, 95%CI(1.025, 1.163), P<0.01; β=1.005, 95%CI(1.001, 1.009), P<0.05; β=1.407, 95%CI(1.052, 1.881), P<0.05)] andSUA, age were risk factors of early renal function decline [β=1.015, 95%CI(1.00, 1.023), P<0.01; β=1.098, 95%CI(1.006, 1.199), P<0.05]. Conclusion SUA is independently associated with albumnuria and renal function decline in type 2 DM patients.  相似文献

Adiponectin is a novel collagen-like protein synthesized by white adipose tissue. Its levels are decreased in obesity, type-2 diabetes and insulin-resistant states, and are increased in chronic renal failure. It has anti-inflammatory and anti-atherogenic properties. This study was planned to evaluate the levels of adiponectin in uremic patients with and without diabetes and to find any relationship between adiponectin levels and some cardiovascular risk factors, and to determine the possible predictive value of adiponectin for cardiovascular complications (CVC). The study included 100 subjects, 20 of them were healthy subjects and served as the control group (group I), 40 were uremic non-diabetic patients (group II) (half of them were without CVC, group IIA, and the other half were patients with CVC, group IIB) and, lastly, 40 uremic diabetic patients (group III) (half of them were without CVC, group IIIA, and the other half were patients with CVC, group IIIB). All subjects were subjected to complete clinical examination, including determination of mean arterial blood pressure (MABP), body mass index (BMI), waist to hip ratio, routine laboratory investigations, fasting plasma glucose, fasting plasma insulin, lipid profile (cholesterol, TG, LDL, HDL), determination of insulin resistance by homeostasis model assessment index (HOMA-IR) and estimation of serum levels of adiponectin. There was a significant increase in serum adiponectin levels in all the uremic patients (group II and group III) when compared with the control (group I) group, P <0.01; also, serum adiponectin levels were significantly decreased in uremic diabetic patients (group III) when compared with uremic non-diabetic patients (group II), P <0.01; but this was still higher than in the controls. The patients with CVC, whether uremic non-diabetic (group IIB) or uremic diabetic (group IIIB), had a significant decrease in serum adiponectin levels when compared with patients without CVC (group IIA and group IIIA), P <0.01. Serum adiponectin has a significant positive correlation with HDL and a significant negative correlation with MABP, BMI, plasma insulin, HOMA-IR, LDL, TG and cholesterol in all the patients. Therefore, it can be concluded that adiponectin levels in uremic patients, whether diabetic or non-diabetic, may be a good indicator of cardiovascular disease risk.  相似文献
