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.

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.

Clinical Study on Jiang Tang San（降糖散）in Treating Non－Insulin Dependent Diabetes Mellitus Patiente

The therapeutic effect of Jiang Tang San (JTS) on 30 cases with non-insulin dependent dia-betes mellitus (NIDDM) , was observed, whose fasting blood glucose ranged trom 11. 1 mmol/L to 13. 8mmol/L. The results suggested that JTS has significant effect on NIDDM patients in lowering blood glucose,blood lipid and blood pressure levels. Clinical symptoms and blood glucose improved rapidly. JTS promotedthe elevation of serum insulin level 1 hour after meal. The total effective rate of lowering blood glucosereached 86. 7% . The results showed JTS is better than berberine on lowering blood glucose ( P< 0. 01 ) andwhen patients failed to respond to other hypoglycemics or on recurrence JTS was still effective. There wereno marked side-effects during the course of treatment.
