Objective Konno-Rastan procedure is one option to cope with complex multilevel left ventricular outflow tract obstruction (LVOTO),which continues to pose a serious challenge to cardiac surgeons.The aim of this study is to retrospectively analyse indications for Konno-Rastan procedure,and to review the safeguards and pitfalls.Methods Between January 1996 and August 2012,totally 13 children with multilevel LVOTO underwent Konno-Rastan procedure.There were 8 boys and 5 girls.Age at surgeries ranged from 5 to 13 years,and weight from 12 to 51 kg with median of 21 kg.The pathology of this cohort includes:8 cases of congenital aortic valvular stenosis,3 cases of congenital aortic valvular stenosis combined with supravalvular stenosis,1 case of congenital aortic stenosis combined with VSD,coarctation and RVOT obstruction,1 case of aortic stenosis s/p percutaneous balloon aortic valvuloplasty.All patients have secondary diffuse tunnel LVOTO.Diameter of aortic ring ranges from 12.0 to 16.4 mm,and pressure gradient across the stenotic region ranges from 90-151 mm Hg.8 cases were implanted with St.Jude AG19 while 5 cases implanted with St.Jude AG17.Results All 13 cases survived.The 4th patient was implanted permanent epicardial pacemaker for transient Ⅲ AVB.The 4th and 5th patients were found residual ventricular septal repture at the nadir of ventricular incision,one underwent redo procedure while another is being followed up.All cases take cumadine to sustain INR at 1.8-2.5.No death emerges during follow-up period.The motality is 0％,the incidence rate of B is 7.7％,residual VSD 15.4％ and endocarditis 7.7％.Conclusion Konno-Rastan procedure is a promising techi.to relieve LVOTO.However,this complex procedure may lead to several fetal complications.Success of the surgery demands perfect operations.

Pigment epithelium-derived factor (PEDF) is an antiangiogenic factor which is effective in tumour inhibition in a variety of tumours and has not yet been studied in bladder tumour before. In this study the expression of PEDF, interleukin-1α (IL-1α) and -8 (IL-8) in bladder tumours was investigated. Immunohistochemistry was performed on 64 bladder tumour and 23 normal uroepithelium samples. Expression change of the factors was compared with clinicopathological parameters. Correlations between PEDF, IL-1α and IL-8 were analyzed. None of the factors was in relation to gender, tumour occurrence, and size or onset pattern. PEDF (P=0.014) and IL-1α (P=0.049) expression was down-regulated with grade progression. PEDF expression was lower in normal uroepithelium than in papillary urothelial neoplasm of low malignant potential (PUNLMP) (P=0.000) and carcinoma (P=0.009) whilst IL-1α (P=0.000 and P=0.000 respectively) and IL-8 (P=0.000 and P=0.023 respectively) expression was higher in the same grouping. PEDF expression had a negative correlation with IL-8 in PUNLMP (P=0.049, r=-0.578) as well as in tumour grouping (P=0.033, r=-0.276). Deranged expressional change of PEDF, IL-1α and IL-8 could be in relation to loss of differentiation from normal uroepithelium to papillary lesion and eventually to carcinoma.

Objective To explore influence of long-term inhaled glucocoticoids(IGS) on soluble intercellular adhesion molecule-1(sICAM-1)) in children with bronchial asthma.Methods Enzyme-linked immunosorbent assay(ELISA) method was used to detect the serum sICAM-1 level in 36 healthy children and 29 children with bronchial asthma(untreated and post-treated for 3,6 and 12 months).Results 1.Serum sICAM-1 level was significantly elevated in children with asthma and significantly higher than that in normal control group(P

Percutaneous coronary intervention(PCI) has become one of the most important therapeutic methods for atherosclerotic heart disease(AHD),but the following complications such as stent thrombosis and restenosis af- fected its long-term efficacy.Platelet activation was a key component of thrombosis of during perioperative period PCI.As one of the most effective antiplatelet drugs,clo- pidogrel has been established its important role in preven- ting thrombosis during perioperative period of PCI.After several large-scale clinical trials in recent years.

Objective To understand the prevalence and the nursing status of incontinence and incontinence-associated dermatitis (IAD),analyze the risk factors of the occurrence of IAD,and to provide effective measures for the prevention and management of IAD.Methods Using the questionnaire survey, 1 318 hospitalized patients in 2 grade three hospitals of Suzhou were investigated,and then the results were analyzed.Results The prevalence of incontinence was 10.70％(141/1 318),among the prevalence of urinary incontinence was 4.63％(61/1 318),fecal incontinence was 4.32％(57/1 318);with 24.11％(34/141) of incontinent patients having IAD;disposable pad and briefs were the most common containment devices,only 36.17％ (51/141) of the incontinent inpatients using skin protectant after perineal skin clean.Single factor analysis revealed that IAD was related with wards, types of incontinence, character of stools, frequency of feces, antibiotics, modes of nutrition support, Braden scores, level of albumin and prealbumin.Unconditional Logistic regression indicated that risk factors of IAD included the level of serum albumin (OR=0.769, P＜ 0.05), Braden scores(OR=0.335, P＜ 0.05) and frequency of feces(OR=11.076, P ＜ 0.05).Conclusions Incontinence and IAD are common in hospitalized patients,low serum albumin, low Braden scores and high frequency of feces are the risk factors of IAD.The clinical nurses have not paied enough attention on the prevention of IAD, lacked relevant knowledge and skin care regimen.

Simvastatin is a hypolipidemic drug that inhibits hydroxymethylglutaryl coenzyme A (HMGCoA) reductase to control elevated cholesterol,or hypercholesterolemia.Previous studies have shown that simvastatin may attenuate inflammation in ischemia-reperfusion injury and sepsis.Herein,we hypothesized that simvastatin may prevent rats from lipopolysaccharide (LPS)-induced septic shock.In our study,rats were divided into a saline group,an LPS group and an LPS plus simvastatin group.Male Sprague-Dawley (SD) rats were pretreated with simvastatin (1 mg/kg) for 30 min before the addition of LPS (8 mg/kg),with variations in left ventricular pressure recorded throughout.Ninety min after LPS injection,whole blood was collected from the inferior vena cava,and neutrophils were separated from the whole blood using separating medium.The neutrophils were then lysed for Western blotting to detect the levels of urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1).In addition,mesentery microcirculations of inlet diameter,outlet diameter and blood flow rate were measured in all three groups.The results indicated that simvastatin significantly promoted heart systolic function and increased the level ofuPA while simultaneously inhibited the expression of PAI-1 as compared with LPS group.Moreover,simvastatin reversed the LPS-induced inhibition of mesentery microcirculation.Taken together,it was suggested that simvastatin can effectively protect the rats from LPS-induced septic shock.
