RESUMO
Objective:To explore the relationship between carotid atherosclerosis (CAS) and bone metabolism marker osteocalcin (OC) in patients with type 2 diabetes (T2DM).Methods:A total of 100 patients with T2DM admitted to Shaoxing People's Hospital (Shaoxing Hospital, Zhejiang University) from January 2018 to August 2018 were selected as study subjects, and the carotid intima-media thickness (IMT) was detected.The patients were divided into CAS group and normal carotid IMT group (NC group), with 50 cases in each group.The levels of OC, fasting plasma glucose(FPG), fasting insulin(FINS), glycosylated hemoglobin(HbA1c), total cholesterol (TC), triglyceride (TG), high density lipoprotein(HDL-C), low density lipoprotein (LDL-C), insulin resistance index (HOMA-IR) were compared between the two groups.Results:The OC level of the CAS group[(11.86±4.46)ng/mL] was significantly lower than that of the NC group[(23.94±4.52)ng/mL] ( t=-9.640, P=0.001). The LDL-C level of the CAS group[(2.89±0.82)mmol/L] was significantly higher than that of the NC group[(2.55±1.16)mmol/L]( t=2.03, P=0.049). Pearson correlation analysis showed that IMT was positively correlated with age, LDL-C, HbA1c ( r=0.285, 0.190, 0.173; P=0.000, 0.020, 0.035), and negatively correlated with OC ( r=-0.603, P=0.000). Conclusion:CAS in patients with T2DM is closely related to OC, and the reduction of OC levels may be a risk factor for CAS in T2DM patients.
RESUMO
Objective To investigate the efficacy of ultrashort and short-acting insulin after subcutaneous insulin infusion pump under glucose monitoring in treatment of diabetes.Methods 110 cases with type 2 diabetes were selected,they were randomly divided into two groups with a random number table:the study group and the control group,55 cases in each group.The study group was treated with short -acting insulin after subcutaneous injection of insulin pump,the control group was treated with short -acting subcutaneous insulin infusion by insulin pump therapy, glucose monitoring system was used to monitor glucose during treatment of the two groups.The clinical efficacy after a month of treatment was observed.Results Before treatment,fasting blood glucose(FPG),postprandial 2 h blood glucose(2h PG),bedtime blood glucose of the two groups had no statistically significant differences.After treatment, FPG and 2hPG,bedtime blood glucose in the study group were (6.01 ±1.06)mmol/L,(7.90 ±0.50)mmol/L, (7.13 ±0.95)mmol/L respectively,which of the control group were (5.98 ±1.04)mmol/L,(7.91 ±0.48)mmol/L, (7.14 ±0.94)mmol/L,which were significantly lower than before treatment (t =9.843,23.669,13.569,9.683, 22.881,13.710,P 0.05).The blood glucose time and insulin dosage in the study group were (5.59 ±1.30)d,(39.98 ±11.01)u/d,which of the control group were (6.98 ±1.40)d,(51.89 ±11.97)u/d,and there were significant differences between the two groups(t =1.825,5.431,P <0.05).The mean blood glucose,blood glucose standard deviation,time percentage of blood glucose≥10 mmol/L,time percentage of blood glucose≤3.9 mmol/L in the study group were (5.95 ±0.61 )mmol/L, (1.28 ±0.25)mmol/L,(14.16 ±2.13)%,(6.35 ±1.45)%,which in the control group were (6.59 ±0.94)mmol/L, (1.54 ±0.29)mmol/L,(15.15 ±2.14)%,(7.96 ±1.42)% respectively,and the differences were statistically significant between the two groups(t =4.236,503.6,2.432,5.883,P <0.05).Conclusion Glucose monitoring system in monitoring blood glucose is accurate and reliable,ultra -short -acting insulin after subcutaneous insulin pump infusion in treatment of diabetes is better than short -acting insulin.
RESUMO
Objective To investigate the correlation between the expression of mononuclear cells Inter-leukin-18(IL-18)and early renal damage in diabetic patients.Methods 480 cases with type 2 diabetes mellitus (T2DM)in our hospital from Jan.2010 to Dec.2012 were selected.According to urine albumin excretion rate, They were randomly divided into diabetic group, micro proteinuria group, and proteinuria group.160 cases of normal people were selected as the control group.Glycosylated hemoglobin, serum cholesterol, serum triglycer-ides, serum creatinine, blood urea nitrogen.2 h postprandial blood glucose and urine protein were detected.Af-ter mononuclear cells being isolated and cultured for 12 h and 24 h, IL-18 was detected.-137G/C and-607C/A gene polymorphism were detected.Results Normal group were significantly lower than diabetes group, micro proteinuria group, and proteinuria group(P<0.01)in BMI, 2 h postprandial blood sugar, cholesterol, glycosy-lated protein, urea nitrogen and serum creatinine index.Micro proteinuria group and proteinuria group were high-er than diabetic group in 2 h blood sugar, cholesterol, glycosylated protein, urea nitrogen and serum creatinine index(P<0.05).Diabetes group, micro proteinuria group, and proteinuria group were significantly higher than normal group in urine protein, 12 h IL 18 and 24 h IL-18(P<0.01).Micro albuminuria and proteinuria group was significantly higher than diabetic group in urine protein, 12 h IL 18 and 24 h IL-18(P<0.01).There were positive correlation between urine protein and 12 h, 24 h IL-18(r=0.454, P<0.01; r=0.479, P<0.01). There was statistical difference between albuminuria group and diabetes group in -137G/C genotype frequency (χ2 =5.45, P<0.05) and there was statistical differencebetween the allele frequency distribution(χ2 =5.76, P<0.05) .Conclusions IL-18 can be used as an indicator for detecting early renal damage.Gene -137G/C polymorphism may increase the risk of diabetic nephropathy by upregulating the expression of IL-18.
RESUMO
Angiopoietin-2 levels were 5. 80 ( 3. 83-8. 00 ) , 4. 42 ( 2. 56-5. 55 ) , and 2. 75 ( l. 40-4. 64 )ng/ml in type 2 diabetic patients with proliferative retinopathy, patients with non-proliferative retinopathy, and patients without retinopathy, respectively. Statistical significances existed between any two groups (all P ＜0. 01 ). Angiopoietin-1 level in patients with non-proliferative retinopathy was higher than that in patients without retinopathy [10. 57 ( 8. 99-12. 05 ) vs 9. 21 (7. 71-11.2 ) ng/ml, P＜0. 05]. No difference in receptor Tie-2 was found among the 3 groups (P＞0. 05 ). The results suggested that serum angiopoietin-2 level might be associated with the severity of retinopathy in type 2 diabetic patients.
RESUMO
Objective To investigate the relationship between serum omega-3 polyunsaturated fatty acid (ω-3PUFA) and insulin resistance(IR) in patients with type 2 diabetes mellitus and non-alcoholic fatty liver disease (NAFLD). Methods This trial involved 51 patients of type 2 diabetes mellitus with NAFLD (G4 group), 50 patients of type 2 diabetes alone(G3 group), 45 patients of NAFLD alone (G2 group) and 42 healthy control subjects (G1 group). Serum ω-3PUFA profile was analyzed with capillary gas chromatography. Insulin resistance was assessed by homeostasis model assessment (HOMA-IR). ALT, AST, γ-glutamyltransferase(GGT) and serum lipids were measured. Results The levels of HOMA-IR were higher in G4 group than those in G3, G2 and G1 group(4. 90 ± 2. 54 vs 2. 38 ± 1.23, 2. 20 ± 1.15, 1.13± 0.42;P<0.05). The level of ALT, AST, GGT, TC, TG, LDL-C were higher in G4 group than those in G3, G2 and G1 group(P < 0. 05). The level of ω-3PUFA was signifieantly lower in G4 group than those in G3, G2 and G1 group(5.68 ±2.02 vs 7. 17 ±2. 38, 6.97±2.32, 10.08±2.76;P <0.05). ω-3PUFA cocentration was negatively correlated with HOMA-IR, TC, TG and LDL-C (r = -0.491, -0. 376, - 0. 462, - 0. 408, P < 0. 05). Conclusions Serum ω-3 PUFA is significantly decreased in patients with type 2 diabetes mellitus and NAFLD. Serum ω-3PUFA is negatively correlated with insulin resistance. ω-3PUEA plays a very important role in the development of diabetes mellitus and NAFLD.
RESUMO
