RESUMO
Objective To investigate the polymorphism of peroxisome proliferator-activated receptors-?2(PPAR-?2) and its association with obesity in Chinese population.Methods According to BMI,89 subjects who are in normal body weight range and 116 overweighted and obese subjects were included in this study.Their Pro12Ala mutation in the PPAR-?2 gene was detected by PCR restriction fragment length polymorphism.Results Allele frequency of Ala mutation of PPAR-?2 in overweighted and obese subjects(qA=11.64%) was significantly higher than that of normal body weight group(qA=5.06%,P
RESUMO
Objective To investigate the association adiponectin gene polymorphism with primary macroangiopathy in diabetes mellitus. Methods Type 2 diabetes mellitus (T2DM) patients were included, 56 patients complicated with atherosclerosis (AS) and 120 non-AS group. We evaluated their Gly15Gly polymorphism of adiponectin gene by PCR restriction fragment length polymorphism (PCR-RFLP). Results The AS patients were more likely to have GG genotype than the non-AS patients (25.0% vs 6.2%, P
RESUMO
Objective To investigate the therapeutic effects of rhein on experimental diabetic nephropathy in rats. Methods Rat model of diabetic mellitus was established by interperitoneal injection of streptozotocin (50 mg/kg) . Renal damages and changes of endothelin (ET) in urine and renal tissues were observed at 12 weeks after the induction of diabetic mellitus and after treatment with rhein (70 mg/kg). Results Compared with the normal rats, at 12 weeks after hyperglycemia, diabetic rats had decreased renal weight/body weight(RW/BW), significantly increased mean glomerular plane area (MGPA), mean glomerular volume (MGV), creatinine clearance rate (Ccr), blood urea nitrogen (BUN), and 24 hour urinary protein excretion (UPE) ( P
