Objective To investigate prevalence of metabolic syndrome (MS) and its related factors in patients with maintaining hemodialysis (MHD). Methods A total of 162 cases on MHD in Beijing Chaoyang Hospital during June to December 2010, were enrolled in this study and divided into MS group and non-MS group according to the diagnostic criteria for MS set by the International Diabetes Federation. Anthropometric and blood biochemical characteristics of the two groups were compared with t-test and x2 test Risk factors for MS were explored with binary logistic regression analysis. Results Prevalence of MS was 40. 7% (66/162) . There was significant difference found in body mass index [(24. 2 ±3. 1) vs. (21. 6 ±2. 7) kg/m2], waistline circumference[(93 ±8) vs. (79 ±7)cm] , white blood cell count [(6. 8 ± 1. 5) × 109/L vs. (5. 6 ± 1. 4) × 109/L] , hypersensitive serum C-reactive protein [(7 ± 5)vs. (4 ±3) mg/L], high-density lipoprotein-cholesterol [(0. 99 ±0. 26)vs. (1.39 ±0.39) mmol/L], low-density lipoprotein-cholesterol [(2. 5 ± 0. 8) vs. ( 2. 1 ± 0. 7) mmol/L], triglyceride ( TG) [( 2. 1 ±1.1 )vs. (1.3±0.8) mmol/L], fasting blood glucose [(5.9±2. 7)vs. (4.8±1.3) mmol/L], serum level of iron [(16±7)vs. (13 ±5) μmol/L], uric acid [(429±114) vs. (388±88) (μmol/L], and carbon dioxide combining power (CO2CP) [(22 ±4)vs. (23 ±4) mmol/L]between MS group and non-MS group (All P < 0.05 ) . But there was no significant difference found in subjective global assessment of nutritional status (SGA) , thickness of skin fold of the triceps muscle (TSF) between the two groups (Both P > 0.05). Binary logistic regressive analysis revealed that serum level of iron (OR = 1.058,95% CI = 1.001 -1. 119), white blood cell count ( OR = 1. 786,95% CI = 1. 346 - 2.371) and hypersensitive serum C-reactive protein (OR = 1. 101,95% CI = 1.010 - 1.201 ) were independent risk factors for MS in MHD patients. Conclusions Morbidity of MS is high in patients with MHD, involved with inflammation process. Serum level of iron, white blood cell count and hypersensitive serum C-reactive protein are independent risk factors for MS in patients with MHD and no inevitable connection between MS and nutritional status in them is found.

From the view of ergonomics study,the importance of optimized design for human-computer coordination work is presented. Through the analysis of probably reasons for the ergonomics accidents in the process of human-computer coordination work,the methods and realization of the optimized design are given out. Furthermore,the studies of human-computer systematization design in preventing the accidents are also discussed.

Objective To compare the clinical utility of s7 and s670 intracoronary sents in the management of patients with coronary artery disease. Methods The clinical follow-up outcomes of 68 patients after implantation of s7 (n=32; group Ⅰ) and s670 (n=36;group Ⅱ) intracoronary stents were retrospectively analysed. Results The successful procedure rates were 100% in group Ⅰ and 97.2% in groupⅡ. The follow-up period was six months for both groups. In group Ⅰ, there were no death, no re-infarction and no revascularization but 2 patients experienced reccurrence of angina ( 6.25%). In group Ⅱ, there were 1 death, 1 patient undergoing revascularization, 3 patients suffering from reccurrence of angina ( 13.8%). Conclusions Both s7 and s670 intracoronary stents appear to be safe and effective in the treatment of coronary lesions with favorable outcomes.

Objective To study the relationship between sex hormones and uric acid in elderly women with coronary heart disease. Methods One handred and fifteen post menopausal female patients were divided into two groups by angiographic results, CAD group (n=61)and control group(n=76).Their serum concentrations of sex hormones and uric acid and general characteristics were compared. Results Baseline clinical characteristics were similar between the two groups,except patients in the CAD group were more likely to have hypertention and diabetes mellitus than the control group .Serum concentrations of estradiol and progestin and androgen showed little difference between CAD and control group,meanwhile, serum uric acid was higher(345.6?96.5 vs 307.9?85.5, P

Mother-to-child transmission (MTCT)is an important way of hepatitis B virus (HBV)transmission.Blocking the HBV MTCT has a great significance for the prevention and treatment of hepatitis B.This article reviews the current blocking strategies implemented in the antepar-tum,peripartum,and postpartum stages,and summarizes the controversies existing in the blocking strategies in different stages.The significance of HBV occult infection and germ cell transmission in the HBV MTCT is analyzed.The results indicate that the current strategies for the prevention of hepatitis B MTCT need further improvement.Attentions should be focused on HBV occult infection and germ cell transmission.

Objective To observe the effect of fluvastatin on urinary albumin excretion rate(UAER)of microalbuminuria in type 2 diabetes patients.Methods Type 2 diabetes patients with mieroalbuminuria were randomly divided into fluvastatin goup(n=126)and control group(n=129).Fluvastatin group was given fluvastatin 40 mg each night.Follow up was conducted for 1.5 years.The UAER and glomerular filtration rate(GFR)as well as blood lipid level before and after therapy were compared.Results UAER in fluvastatin group was significantly lower than that in control group[(59.6±10.5)vs(87.5±12.3)mg/min,P＜0.05]before therapy[(104.4±25.2)vs(110.6±19.7)mg/min,P＜0.05],which was independent of its lowering-lipid effect.But GFR had no signifimicroalbuminuria which is independent of lowering-lipid effect in type 2 diabetic nephropathy patients and delay the progress of diabetic nephropathy.

Objective To investigate the safety and effectiveness of transurethral bipolar plasmakinefic resection in treating urethral stricture. Methods Totally 46 patients with urethral stricture were treated with transurethral bipolar plasmakinetic resection, and they were followed up for 3～12 months to observe the clinical effects. Results The segments of urethral scar were accurately incised and resected in all the 46 cases,24～26F bougies could pass through the urethra smoothly, and miction should be kept unobstructed. Totally 41 cases were followed up postoperatively, the maximal flow rate(Qmax) was ( 18.6±4.1 ) ml/s, which was obviously ameliorated as compared with that before operation(t=14.25, P＜0.05);sexual function had no obvious changes before and after operation;no serious complications of urethral massive bleeding, urinary incontinence, fistula of urethral diverticulum,urethral perforation, rectal injury, etc. was observed. Conclusion Transurethral bipolar plasmakinetic resection is an effective method for treating urethral stricture, because it has fewer complications, faster postoperative recovery and lower recurrence.

ObjectiveTo investigate the effects and mechanism of rosuvastatin on the expression of tissue factor in cultured human monocyte-macrophages cells which was induced by oxidized low density lipoprotein(ox-LDL).MethodsThe human monocyte-macrophages cells were divided into four groups:control group,ox-LDL group,Poly-inosine monophosphate (Poly Ⅰ) group,rosuvastatin group.The expression of LOX-1mRNA and TF mRNA was assayed by RT-PCR.The ELISA was performed to determine the protein concentration of TF.ResultsCompared with control group,the expression of LOX-1 mRNA and TF mRNA was increased in the ox-LDL group[ (3.25156±0.15772) vs (1±0) ; (2.522451±0.138967) vs (1±0) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the expression of LOX-1 mRNA in the Poly-inosine monophosphate group and rosuvastatin group,TF mRNA were decreased in the ox-LDL group[ (2.95139±0.157253) vs(3.25156±0.15772) ; (2.877343±0.156558) vs(3.25156±0.15772) ; (1.811956±0.169699) vs (2.522451±0.138967) ; (1.687701±0.174647) vs (2.522451±0.138967)],and it was in a concentration-dependent manner(P＜0.05).Compared with control group,the expression of TF in the ox-LDL group was increased [(207.7233±1.154701) vs (184.8467±0.871799) ],and it was in a concentration-dependent manner (P＜0.01).Compared with the Poly-inosine monophosphate group and rosuvastatin group [(197.8733±1.505003) vs (207.7233±1.154701) ;(202.9567±2.722744)vs(207.7233±1.154701) ],the expression of TF in the ox-LDL group were decreased,and it was in a concentration-dependent manner (P＜0.05).ConclusionsLOX-1 may be responsible for the expression of TF in human monocyte-macrophages cells induced by ox-LDL.Rosuvastatin is able to down-regulate the expression of LOX-1mRNA in human monocyte-macrophages cells through oxLDL,and TF mRNA and TF expression can be reduced.
