ABSTRACT
Objective To compare the effects of fluvastatin and valsartan on the inflammatory cytokines in the early stage of type 2 diabetic nephropathy and their protective effects on to diabetic nephropathy. Methods Ninety patients with early stage of type 2 diabetic nephropathy were divided into three groups, 30 patients receiving routine hypoglycemic agents (DN1) as control,30 patients receiving routine hypoglycemic agents plus valsartan (DN2) and the other 30 receiving routine hypoglycemic agents plus fluvastatin (DN3). Blood glucose, blood lipid,serum creatinine and C reactive protein(CRP),24-hour urine protein,urinary albumin excretion rate (UAER) and several inflammatory cytokine were measured before and after treatment. Results ( 1 ) No significant difference of the levels of serum CRP,TGF-β1,IL-6,TNF-α, IL-18 at the baseline were observedamong these three groups.In the DN2 group,after treatment,IL.6 was([15.99±2.87]ng/L and[17.64±2. 131 ,P 0. 05). (2) In the subgroup that there was no difference in blood pressure between before and after treatment in both the DN2 and DN3 group,in the DN3 group,UAER was ([63. 1 ±31.7] μg/min and[82.9±40.0] μg/min,t = -2. 145,P 0. 05 ). Conclusion Both valsartan and fluvastatin are able to protect the renal function of patients with type 2 diabetic nephropathy by decreasing the levels of urine proteins and correlated serum inflammatory cytokines.
ABSTRACT
Objective To observe the relationship of liver ultrasound class and urinary albumin excretion ratio (UAER) in type 2 diabetes mellitus (T2DM) combined with nonalcoholic fatty liver disease (NAFLD). Methods One hundred and ninety-seven T2DM patients were divided into 3 groups according to the degree of hepar adiposum: group A (66 subjects without NAFLD), group B (63 subjects with mild NAFLD) and group C (68 subjects with moderate or severe NAFLD). Their clinical indexes,UAER and biochemical parameters were measured and compared, the relative analysis of blood fat, HOMA-IR and UAER was done. Results Compared with those in group A, the levels of UAER were significantly increased [(86.49 ± 65.19) mg/24 h vs. (115.16 ± 101.99) mg/24 h vs. (159.45 ± 149.08) mg/24 h,P ＜ 0.05], and the levels of high density lipoprotein cholesterol decreased in group B and group C[(1.21 ± 0.37) mmol/L vs.(1.05 ± 0.38) mmol/L vs. (0.99 ± 0.21) mmol/L,P ＜ 0.05]. Multiple stepwise regression analysis showed that triglyeride was the most important risk factor affecting UAER(P ＜ 0.05). Conclusions There is a close relationship between NAFLD and UAER in T2DM. In the subjects with moderate or severe NAFLD, the UAER increases which indicates that these patients already have capillary vessel injury apparently.
ABSTRACT
To investigate the relationship among serum vascular endothelial cells(VE) -cadherin, advanced glycation end-products( AGE), and atherosclerotic lesion. 20 healthy subjects and 60 patients with diabetes mellitus,including 30 patients with carotid atherosclerosis (CI), were enrolled.Soluble VE-cadherin and AGE were determined using the enzyme-linked immunosorbent method (ELISA). The relationships among the concentration of soluble VE-cadherin, AGE, and the course of the disease, blood glucose, and blood lipid levels were analyzed with multivariant stepwise regression analysis. The levels of serum VE-cadherin and AGE in the patients with diabetes and CI were higher than those in control group( P＜0. 05 ). There was a significant difference in VE-cadherin between the diabetes group and the CI group( P＜0. 05 ). Serum VE-cadherin levels were positively correlated with serum AGE levels(r = 0. 69, P＜0. 01 ). AGE levels were positively correlated with the diabetes duration ( r = 0. 31, P =0. 02 ). The levels of serum VE-cadherin in diabetic patients are positively correlated with their serum AGE levels. The VE-cadherin seems to play an important role in the development of atherosclerosis caused by AGE.
ABSTRACT
Thyroid peroxidase (TPO) , originally described as thyroid microsomal antigen, is present on the apical surface of thyroid follicular cells and is an antigen involved in cell mediated cytotoxicity. TPO evokes high-affinity, IgG-class autoantibodies (TPOAbs) and TPO-specific T cells that are markers of thyroid infiltration or implicated in thyroid destruction, respectively. Enzyme-linked immunosorbent assay is used most frequently for TPOAb detection and quantification. The other conditions associated with TPOAbs include pernicious anemia, connective tissue disorders, diabetes, inflammatory bowel disease, mood disorders, and fertility-related problems such as miscarriage, infertility, in vitro fertilization failure, pre-term delivery, and postpartum thyroiditis. The detection of TPOAhs is recommended in the investigation of goitre, diagnosis of Graves' disease and Hashimoto's thyroiditis, and the prediction of risk of developing hypothyroidism during subclinical thyroid disease.
ABSTRACT
Objectives To investigate the expression features and roles of the costimulatory molecules and T lymphocyte subsets from patients with chronic nephritis.Methods The expression of the costimulatory molecules CD 28 and CD 137 on PBMC (peripheral blood mononuclear cells) and T lymphocyte subsets from 52 patients with chronic nephritis were studied by immunophenotyping and flow cytometry analysis.Results The T lymphocyte subsets from patients with chronic nephritis showed an obvious imbalance with reversing CD 4/CD 8 ratio,decreasing CD + 4T cells and increasing CD + 8T cells.The expression of the costimulatory molecule CD 28 on T cells was significantly lower compared with normal controls (P
