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.

Scoring methods in injury assessment of rats with trauma combined with seawater immersion / 中华创伤杂志

Objective:To explore and establish the scoring method of injury assessment in rats with trauma combined with seawater immersion, so as to provide a reference for injury assessment in the special environment of trauma combined with seawater immersion.Methods:Sixty-four SD rats were divided into two groups according to the random number table, including hemorrhagic shock group and compound injury group, with 32 rats per group. Each group was divided into trauma combined with seawater immersion group and simple trauma group, with 16 rats per group. In trauma combined with seawater immersion group, the hemorrhagic shock model was placed in 15℃ seawater for 1 hour to start bleeding, and the blood loss was 30% of the total blood volume. The composite injury model caused 10% Ⅱ degree burns and was incised along the vental midline with a length of about 2 cm, and then placed in 15℃ seawater for 1 hour. The death and survival time were recorded.The survival time significantly longer than 4 hours out of water was recorded as survival, and significantly shorter than 4 hours out of water was recorded as death. Data were observed within 9 hours after injury, including the changes of physiological indexes (respiration, blood pressure, anal temperature) and arterial blood gas (blood glucose, pH value, blood lactic acid, arterial oxygen partial pressure, arterial carbon dioxide partial pressure, bicarbate, sodium ion, chloride ion, calcium ion, potassium ion). Each index were compared between trauma combined with seawater immersion group and simple trauma group. According to the survival situation of all the trauma combined with seawater immersion group at 4 hours out of water, the rats were divided into survival group and death group. The indicators affecting survival were screened, and then the scatter plot of each index corresponding to the mortality rate was established. According to the trend of each index in different interval in the scatter chart, the score table of injury condition was established.Results:The total mortality was 28% (9/32) in trauma combined with seawater immersion group, and was 6% (2/32) in simple trauma group ( P<0.05). The survival time in trauma combined with seawater immersion group [(8.1±3.7)hours] was shorter than that in simple trauma group [(11.3±4.8)hours] ( P<0.05). In trauma combined with seawater immersion group, the respiratory rate[(58.8±2.9)times/min] was slower than that in simple trauma group [(100.4±7.2)times/min], blood pressure [(80.0±25.1)mmHg] was lower than that in simple trauma group [(89.8±18.1)mmHg], and anal temperature [22.4(20.1, 25.0)℃] was significantly lower than that in sample trauma group [31.7(30.5, 33.2)℃], pH value (7.1±0.1) was lower than that in simple trauma group (7.3±0.1), and arterial oxygen partial pressure [(196.3±34.1)mmHg], arterial carbon dioxide partial pressure [45.5(35.1, 51.1)mmHg], serum sodium [145(142, 148)mmol/L], serum chlorine [120(115, 125)mmol/L], serum calcium [(1.3±0.1)mmol/L]as well as serum potassium [(3.6±0.8)mmol/L] were higher than those in simple trauma group [(149.4±22.6)mmHg, 29.7(25.6, 34.5)mmHg, 142(139, 144)mmol/L, 118(114, 121)mmol/L, (1.2±0.1)mmol/L, (3.3±0.6)mmol/L] (all P<0.05). There were no significances in other indexes between the two groups ( P>0.05). In death group, the breathing[36(30, 36)times/min], blood pressure [(43.1±21.8)mmHg], anal temperature [(20.0±1.9)℃], pH value (7.1±0.1), and bicarbonate [(12.3±2.2)mmol/L] were significantly inhibited or suppressed compared with survival group [60(48, 78)times/min, (86.6±19.3)mmHg, (23.0±3.1)℃, 7.2±0.1, (14.6±2.3)mmol/L (all P<0.05). While the two groups showed no significant differences in other indices ( P>0.05). Therefore, the respiration, blood pressure, rectal temperature, pH value and bicarbonate that significantly affect the survival of rats were screened. According to the death rate corresponding to different intervals, a score value was assigned to the interval as the weight of its impact on survival, namely on the severity of the injury, and an injury score table for trauma combined with seawater immersion in rats was established. The injury scoring scale <6 points indicated no death, 6-9 points indicated the mortality of 50%, ≥9 points indicated the mortality of 71%. The 6 points and 9 points were cutoff value of the scale. It can be considered that the scale of <6 points was classified as minor injury, 6-9 points as moderate injury, and ≥9 points as severe injury. Conclusions:The seawater immersion can result in reduced survival time and increased early mortality, manifested as respiratory depression, more serious blood loss, severe hypothermia, severe metabolic acidosis, water and electrolyte disorders (high sodium, high chlorine, high calcium, and high potassium), etc. According to the respiration, blood pressure, anal temperature, pH value and bicarbate, which affect the survival of rats, the injury rating scale of rats with trauma combined with seawater immersion can be established by using the scatter chart. The predicted mortality rate by using the rating scale was roughly consistent with the actual mortality rate, so the injury rating scale basically had a good prediction and hint for the trauma rats combined with seawater immersion.

Long-term study of pathological changes of living renal grafts from elderly relatives in young recipients / 器官移植

Objective To investigate the safety of young recipients undergoing living donor renal transplantation from elderly relative donors through long-term follow-up of the pathological changes. Methods According to the age of donors, 28 young recipients were divided into the observation group (n=14, elderly donors) and control group (n=14, young and middle-aged donors). The 7-year survival after renal transplantation, the serum creatinine (Scr) levels at various postoperative time points were compared between two groups. The chronic pathological injury scores of renal allograft biopsy at time-zero, postoperative 6-month and 7-year were compared between two groups. The expression levels of renal interstitial fibrosis indicators connective tissue growth factor (CTGF), transforming growth factor (TGF)-β, laminin (LN), fibronectin (FN), cell senescence indicators intercellular connexin (Cx)-43 and mammalian target of rapamycin (mTOR) at postoperative 6-month and 7-year were compared between two groups. Results The 7-year survival rates in the observation and control groups were 78.5% and 92.8% with no statistical significance (P > 0.05). In the observation and control groups, the levels of Scr were 190 and 160 μmol/L at the postoperative 7 d, and 170 and 125 μmol/L at postoperative 1 month. At each postoperative time point, the levels of Scr in the observation group were significantly higher than those in the control group (all P > 0.05). The total chronic pathological injury scores of renal transplant biopsy at time-zero in the observation group was significantly higher than that in the control group (P > 0.05), whereas the total chronic pathological injury scores at postoperative 7-year did not significantly differ between two groups (P > 0.05). Within either group, the total chronic pathological injury scores at postoperative 7-year was remarkably higher than those at time-zero and postoperative 6-month (both P < 0.05). The expression levels of CTGF, TGF-β, LN, FN, mTOR, Cx43 of renal transplant tissue at postoperative 7-year did not significantly differ between two groups (all P > 0.05). Conclusions The long-term follow-up outcomes demonstrate that the pathological changes of young recipients undergoing renal transplantation from elderly donors are similar to those from young and middle-aged donors. It is safe and feasible for young recipients to undergo renal transplantation from elderly donors in the pathological perspective.

The levels of angiopoietin-2 in patients with acute respiratory distress syndrome and its value on prognosis / 中华危重病急救医学

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.

Effect of diammonium glycyrrhizinate and astragalus membranaceus injection on the comprehensive score of acute lung injury / 中国中西医结合急救杂志

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.

Evaluation of Lung Injury Score as a Prognostic Factor of Critical Care Management in Multiple Trauma Patients with Chest Injury

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.

Lung Injury Score in Predicting the Outcome of the Patients in the Intensive Care Unit / 대한구급학회지

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.
