ABSTRACT
Objective To investigate the Effects of thyroxine on the level of serum homocysteine and urinary albumin excretion rate in elderly patients with early diabetic nephropathy and subclinical hypothyroidism.Methods Seventy-five patients with early diabetic nephropathy and subclinical hypothyroidism were randomly divided into levothyroxine treatment group and conventional treatment group.Urinary albumin excretion rate (UAER),serum levels of homocysteine,creatinine,and lipids were measured at both pre-and post-treatment of 48 weeks.Results After treatment,serum total cholesterol,low density lipoprotein-cholesterol,triglyceride,thyrotropin,homocysteine,UAER,and serum creatinine in the levothyroxine treatment group were significantly lower than those in the conventional treatment group [(-0.52 ± 0.12 vs 0.31 ± 0.40) mmol/L,(-0.33 ± 0.22 vs 0.24 ± 0.36) mmol/L,(-0.16±0.18 vs0.19±0.29)mmol/L,(-4.4 ± 1.2 vs 1.2 ±0.8)mIU/L,(-1.4 ±2.0 vs0.9± 1.0)mmol/L,(-13 ± 13 vs 10 ± 7) pg/ml,(-2 ± 2 vs 3 ± 2) μmoL/L,respectively,all P＜0.01].Conclusions Treatment with levothyroxine could significantly improve serum lipid profiles and reduce homocysteine,UAER,and creatinine,and exert a protective effect on the kidney in the elderly patients with early diabetic nephropathy and subclinical hypothyroidism.
ABSTRACT
Sixty patients with early diabetic nephropathy (DN) and normal blood pressure were randomly divided into telmisartan treatment and control groups.And the blood biochemical parameters,urinary albumin excretion rate (UAER),the serum levels of homocysteine (HCY) and transforming growth factor-β1 (TGF-β1) were measured at both pre- and post-treatment of 24 weeks.After treatment,the levels ofUAER,HCY [(61 ±26) vs.(98±38) mg/L,(11.70 ±2.86) vs.(14.4±2.8) μmol/L (P＜ 0.01 ) ]and homeostasis model of insulin resistance index,TGF-β1 [ ( 3.17 ± 0.66) vs.( 3.60 ± 0.87 ),(66 ± 14) vs.(77 ± 17 )U/L respectively (P ＜ 0.05 )]in the telmisartan group were significantly lower than those in the control group.It indicated that telmisartan could improve the insulin sensitivity,significantly decrease the serum levels of HCY and TGF-β1,reduce UAER and exert kidney protection effects in the patients with early DN.
ABSTRACT
AIM: To study on antisense oligoncleotides as inhibitor of human acute promyelocytic leukemia (HL-60) proliferation and C-myc protein expression. METHODS: Oligonucleotides with different lengths (18-21 mer) complementary to the definite regions of C-myc mRNA, modified groups (with S replaced O in internucleotide phosphate linkage) and unmodified ones (with natural internucleotide phosphate linkage) were designed and synthesized. These olignucleotides were tested for their activity on HL-60 cell and also for their toxicity on normal lymphatic cells of human. RESULTS: It was found that two of the oligonucleotides complementary to 5′-44-61 and 5′-556-576 the regions of C-myc mRNA exhibited great inhibitory effects (59.5 % and 62.7 %) on growth of HL-60 cells for a definite time. And no toxicity of the two antisense oligonucleotides was found on normal lymphatic cells of human. CONCLUSION: The sequence of antisense oligonucleotides complementary to 5′-44-61 of C-myc mRNA was designed newly by us may be turned into inhibitory medicine of HL-60 cells.
ABSTRACT
0.05 ). CONCLUSION: The qualities of Flos lonicerae from the four different areas were almost the same as that of the control. This method can be used to judge the appraisal of the Flos lonicerae and to distinguish between genuine and counterfeit Flos lonicerae.
