RESUMEN
Aim To study the effect of rosiglitazone(RGZ)on expression and excretion of connective tissue growth factor(CTGF) in renal tissue and urinary of diabetic nephropathy rats.Methods Three groups of rats were studied:normal control group(n=8),STZ-induced diabetic model group(n=8),diabetes RGZ-treatment group(n=8).Urinary CTGF was measured at the 1 st,4 th,6 th and 8 th week,as well as the expressions of CTGF protein(by histochemical staining)at the 8 th week by ELISA.Results The urinary excretion rates of CTGF at 4 th、6 th、8 th weeks and the expressions of CTGF protein in renal cortex at 8th weeks significantly increased in STZ-induced model group compared with those in normal group(P
RESUMEN
411 subjects were divided into six groups according to their FPG levels.And OGTT was carried out.Result showed that along with the FPG increasing, HOMA ?-cell index and ?I30 /?G30 were decreased progressively, and the fasting serum proinsulin level and ratio of proinsulin /insulin were increased markedly.The area under insulin curve decreased gradually when FPG was above 8 mmol/L. In conclusion, FPG is a reflection of islet ? cell function.
