ABSTRACT
Objective:To explore the efficacy and safety of sivelestat, a neutrophil elastase (NE) inhibitor, in the treatment of acute lung injury (ALI) in the intensive care unit (ICU).Methods:A retrospective analysis was performed on 171 patients with ALI in the ICU of the First Affiliated Hospital of Zhengzhou University from June 2020 to June 2021, including 77 patients in the sivelestat group and 94 patients in the conventional treatment group. Acute physiology and chronic health evaluation (APACHE) Ⅱ score, Murray lung injury score, oxygenation index (PaO 2/FiO 2 ratio), inflammatory cytokines (IL-6, IL-10, TNF-α), ventilator-free days (VFD), the length of ICU stay, and the 28-day mortality were collected to assess the efficacy of sivelestat. At the same time, adverse reactions and laboratory test results within 30 days after the use of sivelestat were recorded to assess the safety. Results:Compared with conventional treatment, oxygenation index, Murray lung injury scores, IL-6, IL-10, and TNF-α were significantly improved after 7 days of sivelestat treatment. Compared with the conventional treatment group, the VFD was significantly longer ( P = 0.0119) and the length of ICU stay was significantly shorter ( P = 0.0269) in the sivelestat group. The mortality was 14.29% in the sivelestat group and 22.34% in the conventional treatment group and, with no statistically significant. In the meantime, sivelestat did not increase adverse reactions within 30 days after treatment. Conclusions:Sivelestat treatment is safe and more effective than conventional treatment for ALI patients in the ICU.

ABSTRACT
Objective To study the pathological changes and expressions of NO and iNOS mRNA in the lung tissue of traumatic hemorrhagic shock rats under dry heat environment of desert and their relations to the lung injury.Methods A total of 140 male SD rats were randomly (random number) ivided into the room temperature (25 ℃) environment traumatic hemorrhagic shock group (room temperature group) and the dry heat traumatic hemorrhagic shock groups (dry heat group,temperature 40℃,humidity 10％),respectively,and each groups was further randomly divided into 7 subgroups:the control subgroup,post shock subgroups at 0,0.5,1,1.5,2and 3 h (n =10 in each subgroup).The rats of control subgroup were not treated,and rats of dry heat group were placed in dry heat environment for 60 min,then anesthetized,fixed,and insertion of intravenous indwelling needles and catherization of right carotid artery,jugular vein and the right femoral artery were performed.After stabilization for 10 min,2500 g iron wheel was used to be dropped from 30 m height and vertically hit the upper left femoral of SD rats in order to make comminuted fracture,wounds were quickly dressed after injury.Exsanguination from right femoral artery was kept until MAP maintained at (35 ± 5) mmHg,and resuscitation was carried out after continue monitoring for 60 min.After the establishment of traumatic hemorrhagic shock model in each environment,the rats were sacrificed at given intervals,and thoracotomy was performed to take broncho-alveolar lavage fluid (BALF) and lung tissue.Pathological changes of lung tissues were observed by using HE staining and NO concentration of lung tissue was detected by one-step method,and changes of the iNOS mRNA expressions were detected by using fluorescence quantitative PCR.Then t test,ANOVA and Pearson correlation analysis were used for the data analysis.Results The pathological change in dry heat group at each interval was more severe,and pulmonary histopathological injury score was higher,and the protein exudation was more profuse compared with the room temperature group.NO concentration in lung tissue homogenate of dry heat group was higher than that of room temperature group (t =2.472,P ＜ 0.05),and the difference in NO level between different intervals within the dry heat group was statistically significant (F =6.77,P ＜ 0.01).The NO concentration in dry heat group reached its maximum at 2 h (3.35 ± 0.23) μmol / g and the peak value emerged sooner than that in room temperature group.The difference was statistically significant in overall expression of iNOS mRNA between two groups analyzed with t test (t =3.619,P ＜ 0.01),and there was statistically significant difference between intervals within the dry heat group (F =12.34,P ＜0.01).The values of iNOS mRNA in the dry heat group were higher than those in the room temperature group at the same given intervals,and the peak value appears at 1.5 h in dry heat group,and the room temperature group it began to increase at 2 h.The concentration of NO and the expression of iNOS mRNA were positively correlated with each other in two groups (r =0.680,r =0.376).The expression of iNOS mRNA and lung histopathological injury score was positively correlated in two groups (r =0.846,r =0.899).Conclusions When traumatic hemorrhagic shock occurred in the dry heat desert environment,the lung injury was more severe and appeared sooner than that in the room temperature environment.NO and iNOS played important roles in the secondary lung injury in the wake of traumatic hemorrhagic shock in rats under the dry heat environmengt of desert.
ABSTRACT
Objective To approach the correlation between angiopoietin-2 (Ang-2) levels and degree of lung injury and prognosis and its clinical significance in patients with acute respiratory distress syndrome (ARDS). Methods A prospective observation was conducted. Fifty-three ARDS patients admitted to Department of Critical Care Medicine of Third Affiliated Hospital of Anhui Medical University from January 2012 to March 2014 were enrolled. According to the criteria of the Berlin Definition of ARDS,the patients were divided into mild group (n=15),moderate group(n=22)and severe group(n=16). Meanwhile,ARDS patients were further divided into survival group(n=29)and non-survival group(n=24)according to 28-day outcomes. Twenty cases of non-ARDS patients were served as control. The acute physiology and chronic health evaluationⅡ(APACHEⅡ)score,sequential organ failure assessment(SOFA)score,oxygenation index(PaO2/FiO2),lung injury score(LIS)were recorded within 24 hours after admission. And the plasma levels of Ang-2,interleukin-6(IL-6)and C-reaction protein (CRP)were measured. The independent risk factors of ARDS were analyzed by univariate and multivariable logistic regression. Receiver operating characteristic curve(ROC)was plotted to evaluate the value of Ang-2 in predicting ARDS. Results Compared with non-ARDS group,APACHEⅡ score,SOFA score,LIS score,mortality were significantly increased,PaO2/FiO2 was significantly decreased,and plasma Ang-2,IL-6,CRP were significantly elevated〔APACHEⅡscore:20.7±5.0 vs. 14.1±5.3,SOFA score:7.7±3.5 vs. 3.5±2.1,LIS score:1.69±0.71 vs. 0.28±0.27,PaO2/FiO2(mmHg,1 mmHg=0.133 kPa):159.5±61.3 vs. 394.0±63.2,mortality:45.3%(24/53) vs. 20.0%(4/20),Ang-2(μg/L):4.73(2.59,6.99)vs. 1.22(0.61,1.52),IL-6(ng/L):56.50(27.15,139.90)vs. 13.05(4.38,15.55),CRP(mg/L):95.75(41.74,189.72)vs. 10.56(3.92,21.36),P<0.05 or P<0.01〕. Each index increased or decreased more significantly with the aggravation of the disease. It was shown by correlation analysis that the plasma levels of Ang-2 was significantly positive correlated with IL-6(r=0.468,P=0.000),CRP(r=0.492,P=0.000),APACHEⅡscore(r=0.560,P=0.000),SOFA score(r=0.508,P=0.000)and LIS score (r=0.588,P=0.000),significantly negatively correlated with PaO2/FiO2(r=-0.685,P=0.000). Factors, APACHEⅡ score,LIS score,PaO2/FiO2,Ang-2 and IL-6 founded statistical significance in univariate analysis were analyzed using multivariable logistic regression. High APACHEⅡscore at admission〔odds ratio(OR)=1.316, 95% confidence interval(95%CI)=1.040-1.633,P=0.022〕and increased plasma Ang-2 levels(OR=1.287, 95%CI=1.041-1.760,P=0.038)were the independent prognostic factors for the 28-day mortality in ARDS. The area under the ROC curve of Ang-2 was 0.964,the optimal critical value of Ang-2 was 1.79μg/L,the specificity was 90.0%,and sensitivity was 92.5%. Plasma levels of Ang-2 was better in predicting ARDS than APACHEⅡscore, SOFA score and IL-6. Conclusions The plasma level of Ang-2 was significantly increased in patients with ARDS. The plasma level of Ang-2 was correlated with the severity of acute lung injury and had important prognosis evaluation.
ABSTRACT
Objective To explore the effect of diammonium glycyrrhizinate(DG) and astragalus membranaceus (AM) injection on the clinical comprehensive score in patients with acute lung injury (ALI). Methods According to the random number table method,a prospective random controlled study was conducted in which 60 cases of patients with ALI were divided into a study group and a control group(each,30 cases). Both groups received a comprehensive treatment based on the new guidelines,and the study group was additionally given DG and AM injection(DG 150 mg+AM 20 ml)one time per day for 7 days. The scores of lung injury,acute physiology and chronic health evaluationⅡ(APACHEⅡ)and systemic inflammatory response syndrome(SIRS)were measured at baseline,3rd and 7th day after treatment,and ventilation support time and final disease mortality rate were also calculated in all the patients. Results There were no statistically significant differences between the two groups in the scores of lung injury,APACHEⅡand SIRS before treatment and after treatment for 3 days(all P>0.05),with prolonged treatment,the above indexes were significantly reduced compared with those before treatment in the two groups,and the decreases in scores of indexes in study group was more significant than those in control group after treatment(lung injury score:1.31±0.99 vs. 2.29±1.08,APACHEⅡscore:18.43±8.17 vs. 24.23±6.98,SIRS score:1.69±0.89 vs. 2.60±1.04,all P0.05). Conclusion The results suggest that DG and AM injection improve the scores of lung injury,APACHEⅡand SIRS,and alleviate the lung injury,so that the injection is beneficial to the early weaning from the ventilator to support treatment in patients with acute lung injury,and has certain therapeutic effect on ALI.
ABSTRACT
PURPOSE: Chest injuries in multiple trauma patients are major predisposing factor for increased length of stay in intensive care unit, prolonged mechanical ventilator, and respiratory complications such as pneumonia. The aim of this study is the evaluation of lung injury score as a risk factor for prolonged management in intensive care unit (ICU). METHODS: Between June to August in 2011, 46 patients admitted to shock and trauma center in our hospital and 24 patients had associated chest damage without traumatic brain injury. Retrospectively, we calculated injury severity score (ISS), lung injury score, and the number of fractured ribs and performed nonparametric correlation analysis with length of stay in ICU and mechanical ventilator support. RESULTS: Calculated lung injury score(<48 hours) was median 1(0-3) and ISS was median 30(8-38) in study population. They had median 2(0-14) fractured ribs. There were 2 bilateral fractures and 2 flail chest. Ventilator support was needed in 11(45.8%) of them for median 39 hours(6-166). The ISS of ventilator support group was median 34(24-34) and lung injury score was median 1.7(1.3-2.5). Tracheostomy was performed in one patient and it was only complicated case and ICU stay days was median 9(4-16). In correlation analysis, Lung injury score and ISS were significant with the length of stay in ICU but the number of fractured ribs and lung injury score were predicting factors for prolonged mechanical ventilator support. CONCLUSION: Lung injury score could be a possible prognostic factor for the prediction of increased length of stay in ICU and need for mechanical ventilator support.

Introduction: Lung Injury Score (LIS) provides a quantitative method for scoring acute lung injury that usually occurs after sepsis. The aim of this study is to evaluate the LIS in prediction the patients outcome and determine the relationship between the LIS and mortality rate, acute physiology and chronic health evaluation II (APACHE II) score and multiple organ failure (MOF) score. METHODS: Patients admitted to Intensive Care Unit (ICU), Severance Hospital Yonsei University College of Medicine from November 1995 to March 1996 were included. LIS at admission and discharge, APACHE II score with MOF score and duration of ICU stay between survivors and nonsurvivors were compared. Relationship of LIS between mortality rate and APACHE II score and MOF score were evaluated. RESULTS: LIS is higher in nonsurvivors than survivors at admission and discharge with statistical significance. LIS of survivors and nonsurvivors at discharge was lower and higher than those at admission (p<0.05) respectively. Correlation coeffcient of LIS with mortality rate, MOF score and APACHE II score were 0.60 (p<0.05), 0.23 and 0.17. CONCLUSIONS: LIS score was highly correlated with mortality rate. Therefore LIS is a good predictor of outcome in the intensive care unit.
