Low level of high-density lipoprotein cholesterol predicts contrast induced-acute kidney injury after percutaneous coronary interventions in patients with coronary heart disease / 中华急诊医学杂志

Objective To investigate the relationship of low level of high-density lipoprotein cholesterol to contrast induced-acute kidney injury (CI-AKI) after percutaneous coronary intervention (PCI) in patients with coronary heart disease.Methods A total of 1500 consecutive patients,who underwent PCI from January 2009 to May 2011,were enrolled in this study.There was no limit on age or sex,and all patients were self-identified as Han ethnic group.Patients were excluded from this study,however,if they had a history of malignant tumor,urinary tract infection,nephrectomy operation,chronic peritoneal or hemodialysis,or if they had been exposed to contrast media within the past 14 days.CI-AKI was defined as an absolute increase in serum creatinine ≥44.2 μmol/L or a relative ≥25％ increase in serum creatinine within 72 hours after procedure.Low level of HDL-C was defined as ＜ 1.04 mmol/L.Monofactorial and multivariate analysis was performed to identify risk factors for CI-AKI and low level of HDL-C in these patients.Results Among the 1500 patients with coronary heart disease,CI-AKI occurred in 246 patients after PCI and the overall incidence of CI-AKI was 16.4％.The patients with low level of HDL-C had a higher incidence of CI-AKI than those without it (21.5％ vs.13.3％ in total,P ＜0.01),no matter that they had suffered from chronic kidney disease (39.8％ vs.26.5％,P ＜ 0.05) or not (17.7％ vs.9.7％,P ＜ 0.01).By multivariate analysis,low level of HDL-C was identified as an independent risk factor for CI-AKI and smoke,great BMI as well as anemia were considered as prediction factors for low level of HDL-C.Conclusion The patients with low level of HDL-C have a higher incidence of CI-AKI after PCI.Low level of HDL-C is one of risk factors for CI-AKI after PCI in patients either with chronic kidney disease or not.Great BMI,smoking as well as anemia are independent predictors for low HDL-C level in these patients.

Comparison of Pulmicort and Dexamethasone's curative effects for acute laryngitis in children / 中国生化药物杂志

Objective To compare Pulmicort and Dexamethasone’s curative effects for acute laryngitis in children. Method Children with acute laryngitis were divided into PUL group and DEX group according their therapy methods. The curative effects and recurrence time were compared. Results The efficiency rate in PUL group was significantly higher than in DEX group (P<0.05). The therapy 3 d and post-therapy dyspnea, hoarseness, bark-like cough and stridor score in PUL group were significantly lower than in DEX group (P<0.05), and the recurrence time of dyspnea, hoarseness, bark-like cough and stridor was significantly shorter (P<0.05). Conclusion Pulmicort could significantly improve the symptoms and signs for children with acute laryngitis with few side effects. Its curative effects are better than dexamethasone.

The Preventive Effects of N-Acetylcysteine on Contrast-Induced Nephropathy in Patients Undergoing Elective Percutaneous Coronary Intervention / 天津医药

Objective To investigate the preventive effect of N-acetylcysteine (NAC) on contrast-induced nephropa-thy (CIN) in patients undergoing elective percutaneous coronary intervention (PCI). Methods A total of 521 patients under-went PCI in Tianjin were randomly divided into conventional treatment group (n=261) and NAC treatment group (n=260). NAC treatment group was given oral NAC (600 mg twice daily) for 48 h and 72 h before PCI plug hydration therapy, and the conventional treatment group was given only hydration therapy. The serum levels of creatinine(Scr), urea nitrogen(BUN), creatinine clearance rate (Ccr), C-reactive protein (CRP),β2-microglobulin(β2-MG), tumor necrosis factor-α(TNF-α), inter-leukin-6 (IL-6), superoxide dismutase (SOD), glutathione peroxidase (GPX) and incidence of CIN were detected at admission and 72 h after the procedure. Results (1) There was no significant difference in the incidence of CIN between NAC treat-ment group (6.2%) and conventional treatment group (3.8%,χ2=1.48, P>0.05). (2) There were no significant differences in se-rum levels of Scr, BUN, Ccr, CRP,β2-MG, TNF-α, IL-6, SOD and GPX before PCI ( P>0.05). (3) The serum levels of CRP, SOD and GPX were significantly higher 72 h after the procedure in two groups ( P＜0.05). There were significantly lower se-rum levels in CRP, SOD and GPX in NAC treatment group than those of conventional treatment group ( P＜0.05). There were no significant differences in serum levels of Scr, BUN,β2-MG and Ccr between NAC treatment group and conventional treat-ment group ( P >0.05). Conclusion N-acetylcysteine may have no beneficial effect on the prevention of CIN after PCI.

Expression of tissue factor in pulmonary artery after experimental acute pulmonary embolism / 中华急诊医学杂志

Objective To investigate the expression of tissue factor and explore its clinical significances in pulmonary artery after acute pulmonary thromboembolism.Methods Thirty-four Japanese white rabbits (Level Ⅱ animals) were randomly (random number) assigned into four groups:group A (specimen of pulmonary artery was taken 3 hours after pulmonary embolism,n =8),group B (specimen of pulmonary artery was taken 8 hours after pulmonary embolism,n =8),group C (specimen of pulmonary artery was taken 24 hours after pulmonary embolism,n =8) and control group (pseudo-operations were carried out without injecting autologous blood clots,n =10).The animal model of pulmonary thromboembolism was established by injecting autologous blood clots into jugular vein through a 5F catheter and confirmed by digital subtraction angiography.The mRNA expression of TF in different parts of pulmonary artery was assayed by RT-PCR.The q test was utilized if there was a significant difference in a given continuous variable among three groups analyzed by ANOVA.Results The TF expression in the specimen adjacentto emboli was stable at 3 h,8 h or 24 hours after embolism.The mRNA expression of TF at 3 h and 8 h after embolism was lower in specimen taken from distal-end of morbid pulmonary artery than those adjacent to emboli.While at 24 hours after embolism,there were similar mRNA expressions in specimen either adjacent or distal to emboli.Conclusions The high expression of tissue factor in pulmonary artery tissue adjacent to emboli could lead to locally increased coagulation activity,indicating the necessity of initiating anti-coagulation treatment as soon as possible after acute pulmonary embolism.

The encoding and reconstruction of parallel MRI / 生物医学工程学杂志

The advent of parallel MRI over recent years has prompted a variety of techniques for performing parallel imaging. The main distinguishing feature among these is the specific way of solving the problem of image reconstruction from undersampled multiple-coil data. The clearest distinction in this respect is that between k-space method and image-domain method. The present paper reviews the basic reconstruction approaches, aiming to emphasize the common principles along with actual differences. To this end the treatment starts with an elaboration of the encoding mechanisms and sampling strategies that define the reconstruction task. Based on these considerations, the distinction between k-space and image-domain approaches is given. At the close of this paper are presented discussioins concerning noise propagation and control in parallel imaging and an outlook upon key issues to be addressed in the future.
