ObjectiveTo assess the efficacy of subglottic secretion drainage for preventing ventilatorassociated pneumonia.MethodsData of relevant randomized controlled trials (RCT) from January 1991 to June 2010 were collected,and data were split into two groups,namely draining group and non-draining group.Meta analysis of ventilator-associated pneumonia was carried out for finding the incidence and mortality in patients with mechanical ventilation using the methods recommended by the Cochrane Collaboration.ResultsSeven RCTs met the inclusion criteria and 1647 patients were enrolled.Subglottic secretion drainage reduced the incidence of ventilator-associated pneumonia ( OR =0.45,95％ confidence interval [CI]:0.32 - 0.63 ),primarily by reducing early-onset pneumonia.But the mortalities of ventilator associated pneumonia were not significantly different between the two groups ( OR =1.03,95％ confi dence interval [CI]:0.75 - 1.41 ).ConclusionsSubglottic secretion drainage appeared effective in preventing ventilator associated pneumonia among patients expected to require ＞48 hours of mechanical ventilation,but the mortality was unchanged.

ObjectiveTo observe the modified Xiaoqinglong decoction and its ingredient-reduced prescription on plasma levels of IL-5 and TNF-ct in rats,and to explore its mechanism of treating AR.To make clear the law of combination in modified Xiaoqinglong decoction.MethodsThe modified Xiaoqinglong decoction was divided into six groups,namely,reinforcing qi group,warming yang group,expelling retained morbid fluid group,reinforcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group.90 rats were randomly divided into nine groups,namely,normal control group,model group,reinforcing qi group,warming yang group,expelling retained morbid fluid group,reinforcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group,and the whole decoction group,with 10 rats in each group.Rat model of allergic rhinitis was made by the use of adjuvant systemic antigen sensitization and local attack,the normal control group and model group were fed with normal saline,the other groups were treated with appropriate drugs,once a day oral administration,continuous for 4 weeks.Detected plasma IL-5 and TNF-α levels of each group in rats.ResultsThe contents of plasma IL-5 (16.0±2.7)mg/L and TNF-α (57.5±8.0)mg/L in the model group was significantly increased,while it was significantly reduced in the reinforcing qi group,warming yang group,expelling retained morbid fluid group,refinorcing qi and warming yang group,reinforcing qi and expelling retained morbid fluid group,warming yang to expel retained morbid fluid group with plasma IL-5[each group was (12.9± 3.1) mg/L、(11.8 ±2.8) mg/L、(12.0±2.3) mg/L、(12.3±2.3) mg/L、(11.1±2.1)mg/L、(11.2±2.5)mg/L、(8.42.3)mg/L respectively]and TNF-α[each group was (27.7±5.7)mg/L、(29.5 ± 3.7) mg/L、(31.2 ± 4.9) mg/L、(28.1 ± 2.8) mg/L、(33.4 ± 5.6) mg/L、(26.3 ± 3.9) mg/L、(21.6 ±4.9) mg/L respectively],the whole decoction group effect was significant compared with the other treated groups (P＜0.05).ConclusionThe modified Xiaoqinglong decoction and its ingredient-reduced prescription can regulate plasma levels of IL-5 and TNF-α.The modified Xiaoqinglong decoction had best results in reinforcing qi,warming yang and expelling retained morbid fluid.

ObjectiveTo evaluate the effects of ventilator circuit change frequency on ventilatorassociated pneumonia (VAP).MethodsMeta-analysis of effects of ventilator circuit change frequency on VAP was conducted with study-level data from 1995 to 2010 in Pubmed,Embase,Web of Science databases.ResultsNine articles were included (sample size:20 326 mechanically ventilated patients).Analysis of six articles showed that the incidence of VAP in ventilator circuit change every 2 or 3 days was 4.05％,while 3.65％ in ventilator circuit change every 7 days.Compared with change ventilator circuit every 2 or 3 days,the risk ratio (RR) of VAP in weekly changes was 0.77 [0.54,1.09] ( P =0.14 ).Analysis three articles showed that compared to ventilator circuit change every 7 days with 15.89％ incidence of VAP,the incidence of VAP in circuit change more than 14 days was 14.9％,and RR was 0.98 [0.69,1.39](P =0.91 ).ConclusionsRegular ventilator circuit change frequency in various intervals can't difference in the incidence of VAP in mechanical ventilation patients.

Objective To investigate the effects of direct hemoperfusion with polymixin B-immobilized fiber (DHP-PMX) in patients with sepsis. Methods We searched Pubmed, Embase, Web of Science databases and identified relevant randomized controlled trials (RCT) from January 1995 to May 2010. Meta-analysis of DHP-PMX on mortality and levels of endotoxin in patients with sepsis were conducted using the methods recommended by the Cochrane Collaboration. Results Eleven RCTs were included.Eight of them included the mortality of patients (sample size: 211 DHP-PMX and 178 conventional medical therapy). In total, the mortalities of patients with sepsis in DHP-PMX group and conventional group were 37.4% (79/211) and 68.5% (122/178) respectively. Compared with the conventional medical therapy,DHP-PMX appeared to significantly reduce mortality ( OR =0.24,95% CI 0.16-0.38 ,P ＜0.000 01 ). The results were similar when two RCTs enrolling patients with methicillin resistant staphylococcus aureus (MRSA) infections were excluded( OR =0. 27,95% CI 0. 17-0. 45, P ＜0. 000 01 ). When the analysis was limited to the nine studies that reported 28- to 30-day mortality, results were unchanged( OR =0. 29,95% CI 0.17-0.48 ,P ＜0.000 01 ). Six RCTs had the available data of endotoxin. The level of endotoxin decreased 31 ng/L(95% CI 22.46-39.55 ) after DHP-PMX therapy, and the decreasing was statistically significant (P＜0. 000 01 ) ,while the level of endotoxin in patients of conventional group did not change (P =0.94).Conclusions This study suggests a favorable effects of DHP-PMX on mortality and endotoxin decreasing in patients with sepsis. However, lack of enough cases and blinding need to be considered. Further investigation with large sample of high quality RCTs is needed.

Objective To evaluate the effects of noninvasive positive pressure ventilation (NPPV)used after extubation on mortality and rate of reintubation in patients with acute respiratory failure (ARF).Method Pubmed, Embase, Web of Science databases were searched to collect data from randomized controlled trials (RCT) of the relevant subject from January 1995 to May 2010. Meta analysis of data about NPPV on mortality and rate of reintubation in patients after extubation carried out by using the methods recommended by the Cochrane Collaboration. Results Six RCTs included sample size of 381 NPPV and 379routine medical care. In total, the mortalities of patients in NPPV group and routine medical care group were 18.6% (62/334) vs. 21.6% (72/333), respectively, and the rates of reintubation of the two groups were 30.2% (115/381) vs. 33.5% (127/379), respectively. Compared with routine medical care, NPPV did not significantly reduce the mortality ( OR: 0.83, 95% CI =0.57 ～ 1.21 ,P =0.34) and rate of reintuation( OR: 0.83, 95% CI = 0.59 ～ 1.16, ( P = 0.27). When the analysis was focused to the four studies of them in which patients received NPPV as soon as extubation, the results were quite different. From these four studies, the mortalities of patients in NPPV group and routine medical care group were 12. 2% (22/181) vs.23.9% (44/184),(P=0.004), and the rate of reintubation of the two groups were 14.0% (32/228) vs.20.4% (47/230), (P =0.07). Compared with routine medical care, early application of NPPV to patients after extubation reduced the mortality. Conclusions This study suggests the favorable effects of early application of NPPV to patients after extubation on the mortality of acute respiratory failure.

Objective To investigate the changes in circulatory and pulmonary monary angiotensinⅡin rats with acite lung injury(ALI)and explore the role of angiotensinⅡin ALI.Method Thirty S-D rats were randomly divided into control group(n=6)and ALI group(n=24).The ALI group was further divided into four subgroups of observation at various intervals,3,6,9 and 12 hours after administration of lipopolysaccharide (LPS)into the femoral vein(each n=6).The indices rate,blood gas analysis,wet weight/dry weight(W/D)ratio of lung lobes,and pathological changes were successively observed at 3,6,9,and 12 hours after injury.The content of angiotensinⅡin lung tissue and blood plasma were detected at above set intervals by radioimmunoassay.Data of these assays were analyzed by one-factor analysis of variance.Results Compare with the control group,pH and PaO2 of arterial blood in ALI group decreased significantly(P＜0.05)at all intervals and PaCO2 of arterial blood in ALI group decreased significanfly(P＜0.05).at all intervals and PaCO2 of arterial blood and lung W/D weight ratio increased significantly(P＜0.05),and scores of lung histopathology denoted the lung injuried(P＜0.01).After injury of lung,angiotensin Ⅱ content increased markedly in lung homogenate and blood plasma (P＜0.05).Angiotensin Ⅱ content in blood plasma reached peak value at 9 hours,and content of angiotensin Ⅱ in lung homogenates kept on increasing at allintervals of observation.Conclusions A large amount of angiotensin Ⅱ releases into lung tissue and blood plasma during ALI,suggesting systemic and pulmonary rennin-angiotensin systems are activated.

Objective To determine whether urinary neutrophil gelatinase-associated lipecalin (uNGAL) and urinary intedeukin-18 (uIL-18) are early markers of acute kidney injury (AKI) in critically ill patients. Methods Ninety-two critically ill patients were studied for one week after their enrollment into our hospital. During the study, 46 patients who met the RIFLE criteria were selected as AKI group and the remaining 46 patients without AKI taken as a control group. The two groups were matched for age, gender and illness severity. Urine samples were collected daily for one week. The receiver operating characteristic curve was used to evaluate the early diagnostic value of uNGAL, uIL-18 and serum creatininc (SCr). Results As compared with the levels obtained 3 days before the diagnosis of AKI, the uNGAL levels in the AKI group increased significantly (P <0. 05), while uIL-18 and SCr levels did not change 2 days prior to the diagnosis of A KI (all P > 0. 05). uNGAL and uIL-18 levels increased significantly (all P < 0. 05), while SCr levels did not change 1 day prior to the diagnosis of AKI in the AKI group (P > 0. 05). The levels of uNGAL, uIL-18 and SCr did not change significantly in the control group during the study period (all P > 0. 05). Three days before the diagnosis of AKI, concentrations of uNGAL, uIL-18 and SCr were not the predictive of AKI. Two days before the diagnosis of AKI, the area under the curve (AUC) of uNGAL was 0. 840 (95% CI 0. 672-1. 009, P < 0. 05), which indicated that uNGAL was the predictive of AKI while uIL-18 and SCr were not. One day before the diagnosis of AKI, the AUC of uNGAL and ulL-18 were 0. 830 (95 % CI 0. 711-0. 950, P < 0. 05) and 0. 818 (95 % CI 0. 697-0. 938, P < 0. 05), indicating that uNGAL and uIL-18 were the predictive of AKI while SCr was not. Conclusion uNGAL and uIL-18 may be the early predictive markers of AKI in critically ill patients.
