A Study of Factors Related to the Incidence of Cataract in Patients with Non-Insulin Dependent Diabetes Mellitus

Purpose: To investigate the factors related to the development of cataract in patientswith non-insulin dependent diabetes mellitus(NIDDM).Methods: 792 NIDDM patients received ophthalmologic examinations including visualacuity, external status of the eyes, slit lamp microscopy and ophthalmoscopy. Glucose,urea nitrogen (BUN), creatinine (Cr), urine acid (UA), N-acetyl-β2-D-glucosaminidase(NAG), β2-microglobulin(β2-MG) and serum albumin in blood were quantitativelytested. Glucose, pH value, protein, cells, cast and ketobodies in urine were assayed.Diagnosis of cataract was based on lens opacities classification system Ⅱ. Any patientmeeting "NⅡ", "CⅡ" or "PⅡ" level was diagnosed as cataract.Results: The incidence of cataract in this group of NIDDM was 62.37 % (494/792),which significantly related to the duration of the disease course, but not to the sex of thepatient. The occurrence rate of cataract in patients suffering from NIDDM of less thanfive years duration, from five to ten years, and more than ten years was 49.67 % (228/459), 71.84 % (125/174), and 88.68 % (141/159), respectively. The occurrence ofcataract in patients diagnosed of the disease from five to ten years and more than tenyears was much higher than that of those with the course of the disease less than fiveyears( P ＜ 0.05 and P ＜ 0. 001, respectively) . Rising concentrations of blood ureanitrogen, creatinine, glycosylated hemoglobin HbA1c(G-HbA1c), N-acetyl-β2-D-glucosaminidase(NAG) and β2-microglobulin(β2-MG) indicated malfunction of thekidneys, and the rate of cataract occurrence in these patients was higher.Conclusion: This study indicates that prolongation of the duration of non-insulindependent diabetes mellitus, renal dysfunction, as well as poor blood glucose control,may accelerate the development of cataract.

Simultaneous liver, pancreas-duodenum and kidney transplantation in a patient with hepatitis B cirrhosis, uremia and insulin dependent diabetes mellitus

Simultaneous liver,pancreas-duodenum,and kidney transplantation has been rarely reported in the literature. Here we present a new and more efficient en bloc technique that combines classic orthotopic liver and pancreas-duodenum transplantation and heterotopic kidney transplantation for a male patient aged 44 years who had hepatitis B related cirrhosis,renal failure,and insulin dependent diabetes mellitus(IDDM). A quadruple immunosuppressive regimen including induction with basiliximab and maintenance therapy with tacrolimus,mycophenolate mofetil,and steroids was used in the early stage post-transplant. Postoperative recovery was uneventful and the patient was discharged on the 15 th postoperative day with normal liver and kidney function. The insulin treatment was completely withdrawn 3 wk after operation,and the blood glucose level remained normal. The case findings support that abdominal organ cluster and kidney transplantation is an effective method for the treatment of end-stage liver disease combined with uremia and IDDM.

Modified upper abdominal cluster transplantation in patients with end-stage liver diseases associated with insulin dependent type 2 diabetes mellitus

Objective Modified upper abdominal cluster transplantation ( MCT) ,which was inspired by classical cluster transplant technique,has been proven more effective and feasible in the treatment of patients with end stage liver diseases associated with insulin - dependent

The relationship between obese protein and noninsulin-dependent diabetes mellitus

To explore the role of obese protein (OP), the product of the obese gene, in the development of non-insulin-dependent diabetes mellitus (NIDDM). Metbods: Plasma obese protein level was measured by radioimmunoassay in 21 normal subjects, 24 adult obese patients and 20 patients with NIDDM. Results: The levels of the plasma obese protein in NIDDM patients (81. 0±17. 5 pg/ml) were very significantly lower than those in normal subjects (194. 3±17. 7 pg/ml) and obese patients (109.1±16. 4 pg/ml ) (P<0.01). The levels of the plasma obese protein in non-obese NIDDM patients were very significantly lower than those in non-obese normal subjects (P<0.01), and the levels of the plasma obese protein in obese NIDDM patients were very significantly lower than those in obese patients (P<0. 01). The leve1s of the plasma obese protein in NIDDM patients were significantly correlated with polyphagia (P<0.05), but not correlated with the body weight indexes after strict dieting, and the plasma levels of cholesterol, triglyceride, fasting glucose, hemoglobiti A, and the insulin levels during glucose tolerance test (P>0.05). Couclusion: Low plasma level of obese protein is one of the important factors contributing to obesity,and plasma obese protein may be closely related to the generation of NIDDM.

Effects of Supplemented Taohe Chengqi Decoction (桃核承气汤) in Treating Insulin Resistance in Rats with Non-Insulin Dependent Diabetes Mellitus

Objective: To investigate the effect of supplemented Taohe Chengqi Decoction (桃核承气汤,STHCQD) in treating non-insulin dependent diabetes mellitus (NIDDM). Methods: The model of rats withNIDDM was formed with injection of streptozotocin and fed on high calorie diet to study the effects of STHCQDon the release of insulin sensitivity. Results: (l ) Fasting serum glucose, serum insulin, intake of food and waterwere significantly decreased (P < 0. 05 -- 0. 01 ) in STHCQD-treated diabetic rats as compared with untreated diabetic rats, while the insulin sensitivity was significantly increased (P < 0. 05 ). (2) The liver cell membranesfrom STHCQD-treated diabetic rats released the quantity of insulin receptor which inhibited adenylate cyclaseactivity, but this effect was blunted in untreated diabetic rats (P < 0. 05). (3) A significantly increased glucoseoxidation in adipocyte of STHCQD-treated diabetic rats was found as compared with those of untreated diabeticrats (P< 0. 05). Conclusions: STHCQD therapy Increased sensitivity and responsiveness of target cells to insulin, i. e. it might decrease insulin resistance at receptor sites and POst--receptor sites in rats with NIDDM, butcould not.reverse the insulin resistance.

CLINICAL ANALYSIS OF 52 CASES OF JUVENILE DIABETES MELLITUS

The clinical significance of 52 cases of juvenile diabetes mellitus is reported in the article.The ratio of male to female was 1:2.5. 21.2% had the episode of infection prior to the onset of the disease;6.5% had positive family history.It is suggested from the article that more attention should be paid to nontypical cases which would incur misdiagnosis and improper treatment;and it might be necessary to differentiate the ketoacidosis from just positive ketonuria reaction. As for the latter,insulin hypodermic injection probably is more feasible than intravenous effusion.

Novel and emerging diabetes mellitus drug therapies for the type 2 diabetes patient

Type 2 diabetes mellitus is a metabolic disorder of deranged fat, protein and carbohydrate metabolism resulting in hyperglycemia as a result of insulin resistance and inadequate insulin secretion. Although a wide variety of diabetes therapies is available, yet limited efficacy, adverse effects, cost, contraindications, renal dosage adjustments, inflexible dosing schedules and weight gain significantly limit their use. In addition, many patients in the United States fail to meet the therapeutic HbA1c goal of 【 7% set by the American Diabetes Association. As such new and emerging diabetes therapies with different mechanisms of action hope to address some of these drawbacks to improve the patient with type 2 diabetes. This article reviews new and emerging classes, including the sodium-glucosecotransporter-2 inhibitors, 11β-Hydroxysteroid dehydrogenase type 1 inhibitors, glycogen phosphorylase inhibitors; protein tyrosine phosphatase 1B inhibitors, G Protein-Coupled receptor agonists and glucokinase activators. These emerging diabetes agents hold the promise of providing benefit of glucose lowering, weight reduction, low hypoglycemia risk, improve insulin sensitivity, pancreatic β cell preservation, and oral formulation availability. However, further studies are needed to evaluate their safety profile, cardiovascular effects, and efficacy durability in order to determine their role in type 2 diabetes management.

Association Studies of 3 Candidate Genes with Type 2 Diabetes Mellitus in a Chinese Population

Objectives To explore the relationship between the polymorphisms of the selected short tandem repeats (STRs) of the candidate genes and type 2 diabetes mellitus (DM) in a Chinese population,the role of genetic and environmental factors in the development of type 2 diabetes. Methods STRs including D11S916 of uncoupling protein 3 (UCP3) gene,binucleotide repeat (CA)n within intron 6 [HSLi6(CA)] of hormone-sensitive lipase(HSL)gene and D20S501 of protein tyrosine phosphatase-1B (PTP-1B)gene polymorphisms were detected, by poiymerase chain reaction(PCR) ,poly-acrylamide gel electrophoresis and silver staining in 106 patients with type 2 DM and 102 control subjects. Results The allele distribution of UCP3 and HSL gene differed significantly between patients with type 2 diabetes and control subjects (X2 = 26. 12,P<0. 005; X2 = 10. 33,P<0. 005,respectively). For UCP3 and HSL gene,the frequencies of alleles A6,A7,A8 and allele B9 were much higher in diabetic patients than in control subjects (0. 090 vs 0. 020,P<0. 005; 0. 109 vs 0. 015,P <0. 005; 0. 033 vs 0. 000,P<0. 05; 0. 033 vs 0. 005,P<0. 05,respectively),while the frequencies of allele A1 and allele B5 were lower in diabetic patients than in control subjects (0. 090 vs 0. 206,P<0. 005; 0. 057 vs 0. 118,P<0. 05,respectively). At D20S501 locus,The allele distribution of PTP-1B gene had no significant difference in two groups (X2 = 3. 77, P>0. 05). Multi-variate logistic regression analysis showed positive correlation between alleles A6,A7 of UCP3 gene,systolic blood pressure, apolipoprotein B, lipoprotein (a) and type 2 diabetes. Conclusion Our data show that D11S916 of UCP3 gene and HSLi6(CA) of HSL gene polymorphisms are associated with type 2 diabetes in Chinese suggesting that UCP3 and HSL might represent susceptibility genes for type 2 diabetes. D20S501 of PTP-IB gem polymorphism is not associated with type 2 diabetes in Chinese. Alleles A6, A7 of UCP3 gene, systolic blood pressure, apolipoprotein B,Upoprotein (a) may play some role in the development of type 2 diabetes.

Case-control analysis of the <i>ERAP1</i>polymorphism rs30187 in Italian type 1 diabetes mellitus patients

Autoimmune diseases are a heterogeneous group of disorders affecting different organs and tissues whose incidence are increasing worldwide. New tools, such as genome-wide association studies, have provided evidence for new susceptibility loci and candidate genes in the disease process including common susceptibility genes involved in the immunological synapse and T cell activation. Close linkages have been found in a number of diseases, including ankylosing spondylitis, multiple sclerosis, Crohn’s disease and insulin-dependent diabetes mellitus (Type 1 diabetes mellitus). The evidence for some associations with Type 1 diabetes was previously found in the region containing 5q15/ERAP1 (endoplasmic reticulum aminopeptidase 1) (rs30187, ARTS1). Our aim was to conduct the first casecontrol study to test the association between the rs30187 polymorphism of ERAP1 and the development of Type 1 diabetes mellitus in patients selected from continental Italy. All control subjects were matched for the sex, age, ethnic origin and geographical area. Genotyping of the rs30187 polymorphism of ERAP1 was carried out by the allelic discrimination assay on DNA extracted from whole blood. We did not observe a statistically significant prevalence of the rs30187 polymorphism of ERAP1 in our cohort of patients than in controls suggesting a minor contribution of this gene to the pathogenesis of Type 1 diabetes mellitus in Italian patients.

Study of the Pathogenesis of Hypertension Associated with Non-Insulin Dependent Diabetes Mellitus

In order to study the pathogenesis of hypertension associated with noninsulin dependent diabetes mellitus (NIDDM), Plasma glucose, insulin levels at fasting and following an oral glucose load were measured. Na +K +pump and Ca 2+ pump activities of red blood cell membrane were also assessed. Hypertensive patients with normal or impaired glucose tolerance (NGT, or IGT) had hyperinsulinemia. Obese hypertensive patients also had hyperinsulinemia, while nonobese hypertensive patients had no hyperinsulinemia, but exhibited a delay in insulin response to oral glucose tolerance test (OGTT). In multivariate analysis, considering the factors of age, BMI and plasma glucose level, DBP were still positively related to both 30 min insulin level and IAUC, but negatively correlated to activities of Na +K +pump and Ca 2+ pump. These results demonstrated that a link between obesity, hpertension and NIDDM is the insulin resistance and/or hyperinsulinemia.

Prevalences of Diabetes and Hypertension and Their Relationship in Community Population of Jiangsu Province

To determine the prevalences of non-insulin-dependent-diabetes mellitus (NIDDM),impaired glucose tolerance (IGT) and hypertension on urban and rural communities of Jiangsu province,8734 subjects sampled from six areas of Jiangsu were investigated. Blood glucose of 2 h after oral administration of 75 g glucose (2 h BG) was measured. WHO criteria were used for the diagnosis of NIDDMand IGT. Meanwhile epidemiological data were collected. Blood pressure, height, weight, waist and hip girths were measured. The crude prevalence was found to be 5. 82% (men 4.62%,woman 6. 69%) for NIDDM, 5. 87% (men 5. 30%, women 6. 29% ) for IGT and 14. 72% (men 16. 50%, women 13. 43 % ) for hypertension in the population obove 20 years of age. Age-adjusted prevalence was 4. 63% for NIDDM, 5. 07 % for IGT and 11. 19% for hypertension. Age increase (>40 years), obesity (BMI≥27) and central fat distribution (WHR≥0.88) were the risk factors for both diabetes and hypertension. The subjects≥40 years of age and obesity were the high risk population of NIDDM, IGT and hypertension. They were the target population for theprevention and treatment of diabetes and hypertension in the community level. High prevalences of NIDDM,IGT and hypertension were observed in the community population in Jiangsu province. To reinforce the prevention and treatment of these disorders in the province is imperative.

Overview of Type 2 Diabetes Drugs on the Market
