ObjectiveTo assess the effects of short-term (2-7 d) high-dose (80 mg/d) statins in the prevention of contrast-induced nephropathy ( CIN).MethodsWe searched PubMed, Embase,ScienceDirect,Scopus,Ovid andWileyInterScience with the key wordsof “ statins/statin/HMG-CoA reductaseinhibitor” ,“contrast ” and“ nephropathy/nephrosis/nephrotoxicity/kidneyfailure”inall languages from 1996 t0 2010 for RCT that assessed the preventive effect of short-term (2-7 d)high-dose( 80 mg/d) statins on CIN.ResultsFive trials with a total of 1009 patients were identifiedTwo studies were conducted in patients with CKD 3-5 stages ( GFR≤60 ml/min or serum creatinine≥97.2 μmol/L) and the remaining 3 studies were conducted in patients with CKD l and 2 stages.Analysis of the data in patients with CKD 3-5 stages did not reveal a statistically significant difference in CIN incidence between the statins and placebo groups (6.50％vs 7.2％ ).The relative risk ( RR)was 0.89 without evidence of heterogeneity (12 =Oqo,P=O.79).Analysis of the data in patients with CKD I and 2 stages revealed a significantly lower CIN incidence in the statins group( 3.60-/o )than that in the placebo group( 11.9％ ).The RR was 0.28 without evidence of heterogeneity( I2=0%, P =0.87 ). Conclusion Short-termhigh-dosestatins treatment may be benefical in reducing the incidence of CIN in patients with CKD l and 2 stages,while nobenefit has been shown in the patients with CKD 3-5 stages.

Objective To investigate the effects of adenovirus vectors for BTB and cap'n'collar protein homology 1 (Bach1) small interfering RNA (siRNA) on antioxidanffactors and fibrosis related cytokines in lung fibroblasts (MLF) in transforming growth factor (TGF)-β1 induced mouse.Methods Bach1 siRNA recombinant adenovirus vectors and blankadenovirus vectorwere constructed,then the MLF cells were incubated with TGF-β1 (5 ng/ml) for 24 h and infected with blankvector and successful constructed Bach1 siRNAs.The messenger RNA (mRNA) and protein expression of Bach1,heme oxygenase (HO)-1,glutathione peroxidase 1 (GPx1) and nicotinamide-adenine dinucleotide phosphate:quinone oxidoreductase-1 (NQO1) in cell supernatants were determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot.Changes of fibrosis-related cytokines including TGF-β1 and interleukin (IL)-6 levels in cell supernatants were determined by enzyme-linked immunosorbent assay (ELISA).One-way analysis of variance (ANOVA) was performed for multiple group comparisons and LSD test was used to compare the two groups.Results Bach1 mRNA (2.127±0.089) and protein expression increased significantly after TGF-31 stimulation compared with blank group (1.000±0.067,t=-21.77,P＜0.01),as well as the expression of fibrosis-related cytokines TGF-β1 (52±6) and IL-6 (34±6) in cell supernatants increased significantly after TGF-β1 stimulation compared with blank group (26±4,t=-11.11,P＜0.01 and 20±5,t=-5.32,P＜0.01),but the mRNA expression of HO-1 and GPx1 (0.403±0.040 and 0.567±0.112) also the protein expression decreased significantly compared with mRNA (1.000±0.181,t=25.57,P＜0.01 and 1.000±0.212,t=6.68,P＜0.05) and protein expression in blank group.Follow the Bach1 siRNA treatment,Bach1 mRNA (0.153±0.015) and protein levels were significantly downregulated compared with mRNA (2.129±0.089 and 1.973±0.035,F=1835.95,P＜0.01) and protein expression of TGF-β1 and blank vector group,as well as TGF-β1 (26±3) and IL-6 (11±3) expression in cell supernatant were significantly inhibited compared with TGF-31 (52±6 and 34±6) and blankvector group (49±5 and 33±6) (F=22.25,P＜0.01 and F=28.38,P＜0.01).But the mRNA levels of HO-1 (3.303±0.294) and GPx1 (1.840±0.231) in MLF were promoted significantly compared with TGF-β1 (0.403±0.040 and 0.567±0.112) and blank vector group (0.353±0.057 and 0.667±0.090) (F=53.90,P＜0.01 and F=526.25,P＜0.01).Conclusion Silencing Bach1 rescues TGF-β1 induced reduction of antioxidants and increasethefibrosis in MLF cells.The study offers an experimental basis to explore pathogenesis of oxidative stress and antioxidant therapy for connective tissue disease related inter-stitial lung disease.

74 cases of the aged severe craniocerebral injury were presented in this paper, which accounts for 11.9% of the severe craniocerebral injury for the period. Among them, 28 cases died with a morta-lity of 37.8%. The mortality amounts to 51.4% in intracranial hematoma cases. 5 cases over 70 years all died. The reaction capacity becomes lower in old people, so that in craniocerebral injury the early clinical manifestations are difficult to represent the truth.Close observation and the early accurate diag-nosis are rather important. Attention should be paid to the multiple injuries and severe medical con-ditions. Some factors such as early clearance of the intracranial hematoma and prevention of com-plications and hypotension during an operation may reduce the mortality.Prognosis may be affected by such factors as the severity of the primary, injury, the compound injuty, complications, age and the deficiency in cerebral blood supply after cranio-cerebral injury.

Objective To explored the moderate effect of perceived organizational support on job burnout-health complaint relationship and job burnout-task performance relationship. Methods Maslach burnout inventory-general survey, the perceived organizational support scale, health complaint scale and task performance scale were used to test 458 teachers in colleges of Armed Police. Results Emotional exhaustion and cynicism were positively related to health complaint (r = 0. 616,0. 4377;P < 0. 01). Emotional exhaustion and cynicism indicated obviously predicted effect on health complaint(β =0.562, P<0. 01;β =0. 144, P<0.05). Reduced personal accomplishment predicted task performance obviously(β = -0.248, P<0.01). Hierarchical multiple regression showed perceived organizational support can regulate the relationship between emotional exhaustion and task per-formance(△R~2 =0.031, P<0.01). Conclusion Job burnout positively predicted health Complaint. The higher the job burnout was, the more seriously the health Complaint. Reduced personal accomplishment negatively predicted task performance. Perceived organizational support had moderate effect on emotional exhaustion and task performance relationship. It relieved the negative effect of emotional exhaustion on task performance.

ObjectiveTo study the risk factors of spontaneous bacterial peritonitis(SBP) in cirrhotic patients with ascites. MethodsThe clinical data of 186 cirrhotic patients with ascities from February 2005 to March 2010 were retrospectively analyzed were divided into two groups,the one with SBP and the other without SBP. The following factors such as sex, Child-Pugh grade were analyzed with binary logistic regression. ResultsAmong those factors ,3 factors were proved to be risk factors for SBP in cirrhotic patients with ascites by analysis of single and multiple variables. Those were Child-Pugh grade score, serum bilirubin level and ascitic fluid albumin. ConclusionSBP in cirrhotic patients with ascites was affected by many factors. The Child-Pugh grade score, serum bilirubin level and ascitic fluid albumin were independently associated with risk factors of SBP, so it was important to pay attention to those factors in preventing the onset of SBP.

Objective: To research the comparability of water vapor transmission of laminated films for pharmaceutical packaging determined by different instruments, methods and experimental conditions to provide reference and advice for the related inspection personnel.Methods: The principle, test parameters, conditions and scope of application for the testing methods for water vapor transmission in the national standard (GB) and international standards (ISO, ASTM) were compared by using three kinds of instruments based on different testing principles.Results: Different temperature and humidity conditions had great influence on the results of the same instrument.Under the same temperature and humidity, the instrument with different principles had little influence on the test results.Conclusion: Testing personnel should regularly use the standard membrane to calibrate the instrument of the sensor method.The temperature and humidity should be strictly controlled during the test.They should take measurement accuracy, personnel operation and economic loss into consideration to select the suitable method.
