Objective To investigate the risk factors for cardiovascular complications in the elderly persons undergone with dialysis.Methods One hundred and eighteen patients undergone with hemodialysis(HD)or continuous ambulatory peritoneal dialysis(CAPD)at the Eastern Hospital, Tongji University, Shanghai during January 2002 to December 2006 were retrospectively analyzed.They were divided into four groups based oil their age and mode of dialysis, i.e., 44 patients in the elderly HD group(aged over 60years), 16 patients in the elderly CAPD group(aged over 60), 46 patients in medium-age HD group(aged under 60 years)and 12 patients in the medium-age CAPD group(aged under 60).Routine biochemical parameters were measured for all the patients and their difference was compared among the four groups.Logistic regression analysis was performed for the risk factors of cardiovascular complications.Results Pulse pressure(PP)was(66±21)mm Hg, serum level of triglycerides(TG)was(1.28±0.67)mmol/L, serum level of lipoprotein(a)[LP(a)]was(434±202)mg/L, C-reactive protein was(CRP)(21±15)mg/L, serum phosphorous(P3-)was(2.02±0.77)mmol/L, and product of serum calcium and phosphorous(Ca×P)was(4.3±1.6)mmol2/L2, respectively, in the elderly group with dialysis, all significantly higher than those in the medium-age group with dialysis(t=1.535, 1.016, 2.154, 2.252, 4.676, and 4.534, respectively, P＜0.05).Incidence of cardiovascular events was markedly lower in the CAPD group than that in the HD group(P＜0.05), either in the elderly or medium-aged patients.And, incidence of cardiovascular complications correlated positively with age, PP, LP(a), CRP and Ca×P of the patients with dialysis, but correlated reversely with serum level of albumin(all with P＜0.05).Conclusions There exist a few risk factors for cardiovascular complications in the elderly patients with dialysis, so proper mode of dialysis should be selected for those who need it and adequate intervention should be implemented for them to correct the risk factors.

Objective To identify susceptible miRNAs for the pathogenesis of diabetic nephropathy (DN) and the molecular targets of losartan treatment. Methods The 8-week age KKAy mice were divided into losartan treatment group (10 mg· kg-1· d-1) and non-treatment group,C57BL/6 mice were used as the control group.At age of 20 weeks,body weight,random blood glucose,urinary albumin and urinary creatinine were tested,and kidney morphology was observed.Glomeroli were separated by magnetic beads perfusion,and total RNA were extracted.MiRNAs expression profiles were analyzed by the Affymetrix GeneChip miRNAs arrays. Results At age of 20 weeks,KKAy mice developed higher body weight,higher blood glucose and higher urinary microalbumin creatinine ratio than C57BL/6 mice,and the glomerular basement membrane thickened,mesangial matrix widened.Losartan treatment markedly improved the level of urinary albumin creatinine ratio [(539.71±100.23) mg/g vs (728±177.19) mg/g,P＜0.05)] and pathological lesion of KKAy mice.The miRNA array analysis showed that there were 22 miRNAs differentially expressed between KKAy non-treatment mice and C57BL/6 mice glomeruli at age of 20 weeks.Among them,10 miRNAs were up-regulated,and 12 miRNAs were down-regulated.The expression of 4 miRNAs was down-regulated in glumeruli of KKAy mice treated by losartan compared with that of non-treatment mice.The expressions of miRNA-503 and miRNA-181d were significantly up-regulated in the glumeruli of KKAy mice and inhibited by losartan treatment, Conclusion The expressions of miRNA-503 and miRNA-181d are significantly up-regulated in the glumeruli of KKAy mice and inhibited by losartan treatment,which may be new therapeutic targets of DN.

OBJECTIVETo observe the effect and side effect of Danzhi Xiaoyao powder (DXP) in treating depression.

METHODSA randomized controlled and double-blinded study was conducted in 63 cases of depression by divided them into the western medicine group (WMG, 31 cases) treated with maprotiline, and the Chinese medicine group (CMG, 32 cases) treated with DXP. The effect of therapy was evaluated before and at the 2nd, 4th and 6th week of the treatment with Hamilton's depressive scale (HAMD), self-rating depression scale (SDS), self-rating anxiety scale (SAS) and the scale for TCM syndrome and symptom differentiation (TCM-SSD), and the side-effect of therapy was assessed with Asberg side-effect scale as well.

RESULTSThere was no significant difference between the two groups in scores of HAMD, SDS, SAS, and TCM-SSD. The markedly effective rate in CMG was 84% and in WMG 87%, showed no significance between them (P > 0.05). The scores of HAMD, SDS and SAS of both groups were remarkably lowered after therapy (P < 0.05). However, the score of Asberg in CMG was lower than that in WMG (P < 0.05).

CONCLUSIONDXP shows the effect equivalent to that of maprotiline, but with obviously less side-effect.
