The trend of glucose metabolism and affecting factors following liver transplantation / 实用医学杂志

Objective Glucose metabolism trend was dynamicly mornitored following liver transplantation, and its affecting factors were assessed. Methods The glucose metabolism status were assessed at four time points respectively after liver transplants, then they were divided into two groups:normal glucose metabolism (NGM) and abnormal glucose metabolism (AGM). The clinical data were univariate analyzed and multivariate analyzed to screen the risk factors. Results At 1 month, 3 months, 1 year and 3 years post-transplantation, the incidence of AGM were 74.0%, 43.9%, 29.4%, 24.1% respectively Between these two groups, age > 45 y had a significant difference at 1 month, 3 months, 1 year and 3years post-transplantation; the use of tacrolimus had a significant difference at 3 months, 1 year and 3years post-transplantation, but the dose of tacrolimus or tacrolimus blood concentration showed no significant difference; high dose of glucocorticoid had significant difference at 1 month , 3 months post-transplantation; high BMI and acute rejection had significant difference at 1 month post-transplantation. Conclusions There is a high incidence of abnormal glucose metabolism (AGM) in the early stage post-transplantation, and a considerable number of patients' glucose metabolism improved in the later period. Age>45 y and tacrolimus affect glucose metabolism for a longer period post-transplants. High BMI and acute rejection have an impact on glucose metabolism only in the early stage post-transplantation. Large dose of glucocorticoid affect glucose metabolism for at least 3 months post-transplantation , and there is no significant difference after 1 year.

The relationship between serum cystatin C and coronary artery disease in type 2 diabetes mellitus patients with normal uric protein / 中国医师进修杂志

Objective To investigate the relationship between serum cystatin C and coronary artery disease in type 2 diabetes mellitus (T2DM) patients with normal uric protein.Methods According to the coronary artery lesion diagnosed by 320-dynamic volume CT,the 126 T2DM patients with normal uric protein were divided into three groups:no coronary stenosis group (group A,32 cases),coronary atherosclerosis group(group B,38 cases),coronary heart disease group (group C,56 cases).Then the serum cystatin C etc were compared among the three groups.Results The levels of serum cystatin C in group A,B,C were (0.89 ± 0.27),(1.31 ± 0.53),(1.54 ± 0.62) mg/L.With the increase of coronary artery lesions,it gradually increased,there was significant difference among the three groups (P ＜ 0.05).The patients were divided into three groups according to the level of serum cystatin C quartile.The incidence of coronary artery lesion in creased with the increased levels of serum cystatin C.The level of serum cystatin C increased from 75th percentile to 100th percentile,the incidence of coronary heart disease increased significantly (OR =8.32,P ＜0.05).The result of multiple Logistic regression analysis showed that history of hypertension (regression coefficient 4.135,P =0.000),glycosylated hemoglobin (regression coefficient 1.257,P =0.002),low density lipoprotein-cholesterol (regression coefficient 3.381,P =0.015),cystatin C (regression coefficient 2.046,P =0.030) were the independent risks of coronary heart disease in patients with T2DM.Conclusion The level of serum cystatin C may be a predictor for coronary heart disease in T2DM patients with normal uric protein.

Objective To investigate the relationship between dyslipidemia,obesity,insulin resistance (IR)and various degrees of non.alcoholic fatty liver disease(NAFLD)in patients with type 2 diabetes mellitus (T2DM), and the risk factors of NAFLD.Methods Two hundred and sixty-eight patients were divided into three groups(non-NAFLD group,mild NAFLD group,moderate and severe NAFLD group)by liver ultrasonography.Body height(H),weight(W),waist circumference(WC),hip circumference(H)were measured.The levels of fasting blood glucose (FBG),glycosylated hemoglobin A_1c(GHbA_1C),serum total cholesterol(TC),serunl high density lipoprotein(HDL-C),serum low density lipoprotein(LDL-C),serum triglyceride (TG),alanine aminotransferase (ALT)and fasting serum insulin(FINS)were measured.Body mass index(BMI),the waist to hip ratio(WHR)and insulin resistance index(HOMA-IR)were calculated.Unconditional logistic regression model was used to test for the risk factors of NAFLD.Results BMI、WC、WHR、HNS、HOMA.IR、TC、LDL-C、TG and ALT in NAFLD group were significantly higher than those in non-NAFLD group (P<0.05).The levels of BMI、WC、WHR、HNS、HOMA-IR、 TG and ALT increased significantly in moderate and severe NAFLD group compared with mild NAFLD group(P<0.05).TG、WHR and HOMA.IR were the risk factors of NAFLD(P<0.05,OR=2.394,3.273,5.256).Conclusions NAFLD in patients with T2DM had remarkable dyslipidemia,overweight,central obesity and insulin resistance.TG、WHR and HOMA.IR were risk factors of NAFLD.

Effect of sulodexide on islet β-cell function in streptozocin induced diabetic rats / 中国综合临床

Objective To study the effects of sulodexide on islet B-cell function in streptozocin induced di-abetic rats. Methods Sprague-Dawley(SD) rats were randomly divided into normal control group (group C), dia-betic group without treatment(group D), and suledexide treatment group(group S), a single dose of streptozotocin were abdominally injected to establish the diabetic rat models. Each animal in sulodexide treated group was addition-ally fed with sulodexide of 10 mg/(kg·d) for 12 weeks,while the remained group (group C and D) were given normal water in the same period. After 12 weeks of treatment, fasting plasma glucose(FPG),fasting plasma insulin (FINS), activated partial thromboplastin time (APTT), prothrombin time (PT), thrombin time (TT), triglyceride (TG), Low-density lipoprotein cholesterol (LDL-C), serum creatinine rates (SCr) and alanine aminotransferase (ALT) were measured. Insulin sensitivity index(ISI) and insulin resistant index (HOMA-IR) were calculated. Results After 12 weeks, the levels of TG, LDL-C and ALT had no significant difference between group D and group S, but were higher than those in group C (P <0.05);There were no significant difference of SCr levels among the three groups. Compared with the group C, APTT, PT, TT and ISI in group D and S were significantly decreased, HOMA-IR were significantly increased (P < 0.05). APTT, PT, TT and ISI in group S had significantly increased compared with that in group D, HOMA-IR was significantly decreased in group S compared with that in group D (P < 0.01). Conclusions Sulodexide can reduce insulin resistant, improve hypercoagulability and insulin sensitiv-ity in streptozocin induced diabetic rats. The effects to blood lipid, liver and renal functions in diabetic rats are not obvious.

Clinical Investigation of Lower-extremity Arterial Disease in Patients with Newly Diagnosed Type 2 Diabetes Mellitus Combined with Nonalcoholic Fatty Liver Disease / 中山大学学报(医学科学版)

[Objective] To investigate the clinical characteristics and risk factors of lower-extremity arterial disease in the patients with newly diagnosed type 2 diabetes mellitus combined with nonalcoholic fatty liver disease (NAFLD). [Methods] One hundred fifty-one patients were investigated respectively. The patients were divided into two groups (NAFLD-Group and non-NAFLD group) by liver ultrasonography and disease history, then their clinical data were collected and compared in order to find the differences of biochemical indicators and the morbidity of lower-extremity arterial disease between two groups. [Results] Ninety-two cases (60.93%) were complicated with NAFLD. NAFLD group had higher levels of fast insulin and C peptide level, postprandial insulin and C peptide level, uric acid, body mass index (BMI), homeostasis model assessment (HOMA-IR) and lower level of high-density lipoprotein cholesterol and insulin sensitive index than those of without NAFLD (P<0.05). One hundred and one cases(66.89%) were complicated with lower-extremity arterial disease. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group (75% vs. 54.24%, P<0.01). [Conclusion] Both lower-extremity arterial disease and NAFLD are common complicated with type 2 diabetes. The morbidity of lower-extremity arterial diseases was higher in NAFLD group than that of without NAFLD group.

Renal protective effects of sulodexide in diabetic rats and its anti-oxidative mechanism / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the renal protective effects of sulodexide and its anti-oxidative stress mechanism in diabetic rats.</p><p><b>METHOD</b>Thirty male SD rats were randomized into 3 equal groups, namely the control group, diabetic group, and sulodexide treatment group. Twelve weeks after establishment of rat diabetic models and administration of sulodexide, the rats were sacrificed for measurement of the urine volume, body mass, kidney mass/body weight ratio, plasma glucose, and glycosylated hemoglobin (HbA1c). Malondialdehyde (MDA) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-PX) activities in the renal tissue or serum were tested. Electron microscopy was performed to observe the pathological changes in the kidneys.</p><p><b>RESULTS</b>The urine volume, renal mass/body mass ratio, serum glucose, HbA1C, and serum and renal MDA levels all significantly increased in the diabetic rats in comparison with the normal controls (P<0.05). But the body weight and activities of SOD, CAT, and GSH-PX in the renal tissue in the normal control group were significantly higher than those in the diabetic and sulodexide group. After 12 weeks of sulodexide treatment, SOD, CAT, and GSH-PX activities in the renal tissue of rats were significantly increased in comparison with those in the diabetic rats (P<0.05). Electron microscopy showed obvious irregular thickening of the glomerular capillary basement membrane in the diabetic group with vacuolization in the mitochondria in the epithelial cells, and such pathological changes were significantly alleviated in the sulodexide treatment group.</p><p><b>CONCLUSIONS</b>Sulodexide can effectively lower the urinary albumin excretion rate, improve the ultrastructural renal pathologies and prevent glomerular basement membrane thickening in diabetic rats, probably in association with the reduction of the MDA levels and enhancement of SOD, CAT, and GSH-PX activities.</p>

Cost-effectiveness analysis on continuous subcutaneous insulin infusion and multi-point daily insulin injections in the treatment program of type 2 diabetes / 中华流行病学杂志

Objective To observe the cost-effectiveness of using continuous subcutaneous insulin infusion (CS Ⅱ) and multi-point daily insulin injections (MDI) in controlling blood sugar in the newly hospitalized type 2 diabetes patients. Methods Retrospective analysis on 86 cases taking CS Ⅱ and 103 cases using MDI on a 'blood sugar control program' among the newly hospitalized patients with type 2 diabetes. The period for observation was 2 weeks, using cost-effectiveness analysis methods to evaluate the two treatment programs. Results After two weeks of treatment, the effectiveness in the control of blood sugar in CS Ⅱ group was similar to the MDI group, with no significant difference(P<0.05) and the adverse reactions were similar. Costs in the CS Ⅱ program (Yuan/person) was less than in the MDI program (1478.34 vs. 1620.46), with significant differences (P< 0.05). The cost-effectiveness ratios (C/E) were 15.07 in the CS Ⅱ group, and 16.34 in the MDI group, with no significant difference (P>0.05). In order to further reduce the cost of CS Ⅱ group as a reference, the incremental cost-effectiveness ratio (△C/ △E)ofthe MDI group was 129.20. Conclusion Costs-effective of the CS Ⅱ program was better than the MDI one in treating the newly hospitalized patients with type 2 diabetes, suggesting that CS Ⅱ program might be a better choice for hospitals to carry on an intensive insulin therapy program.
