Objective To observe the influence of different altitudes on the basic vital signs of cardiopulmonary resuscitation (CPR) rescuers before and after CPR.Methods The experiment was completed in the Simulated Cabin for Special Environment of Northwest of China. Ninety healthy adult medical staff in General Hospital of Xinjiang Command were randomly and equally divided into 3 groups: plain (normal oxygen), 3700-meter high altitude and 4300-meter high altitude. According to the 2010 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care, the values of heart rate (HR), mean arterial pressure (MAP), respiration rate (RR), arterial oxygen saturation (SpO2), before and after 1 CPR cycle were recorded for statistical analysis and their changes were compared.Results The HR and RR significantly increased (P<0.05), but MAP and SpO2 did not change significantly (P>0.05) in the three groups. The HR and RR was faster in 4300 meter high-altitude than in 3700 meter high-altitude (P<0.05), and was faster in 3700 meter high-altitude than in the plain (P<0.05). But there was no significant difference between the three groups in MAP and SpO2 (P>0.05).Conclusions With the elevation of the altitude, HR and RR may significantly increase in CPR rescuers, but there is no significant influence on MAP and SpO2.

Objective To edit Chinese version of the Minnesota living with heart failure questionnaire (MLHFQ) and to estimate its reliability and validity.Metheds Translated and edited the Chinese version of MLHFQ according to the standard procedures,and tested 83 inpatients which were recruited from three polyclinics of Beijing district in China.Results Cronbach's alpha consistency was>0.80 for the three MLHFQ scores.Reproducibility ranged from 0.48 to 0.84 for items of weighted kappa coefficient and from 0.88 to 0.94 for three do-mains of Spearman's correlation coefficient.MLHFQ scores varied significantly with NYHA functional class(P<0.05),and there were intermediate-to-high correlations with the assumed corresponding SF-36 domains(-0.73 to -0.59).Factor analysis revealed three-factor structure explained 49.34% of the total variance.The MLHFQ scores before and after the treatment combined TCM and western medicine were significant (physical domain (26.15±7.15,17.63±8.50),emotional domain (8.96±5.73,6.8l±5.31),overall score(56.38±16.88,39.77±15.69) all P<0.01).Conclusions The Chinese version of MLHFQ is translated and edited according to the standard procedures.Its reliability and validity is good,and could be used as a clinical outcome measurement.

Objective To investigate the predictive values of serum complement C3, C4 and cholesterol levels in the prognosis of patients with sepsis. Methods The clinical data of all the patients with sepsis admitted to the Department of Critical Care Medicine of the General Hospital of Xinjiang Military Command from January 2015 to January 2017 were retrospectively analyzed. The levels of serum complement C3, C4, cholesterol, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, sequential organ failure score (SOFA), etc. were recorded within 24 hours after admission, the patients were divided into survival group and death group according to the 28-day prognosis, and the differences in various indexes between the two groups were compared respectively;the predictive efficacies of C3, C4 and cholesterol levels in the prognosis of sepsis patients were evaluated by plotting receiver operating characteristic curves (ROC). Results Finally, 120 patients with sepsis were enrolled, including 57 patients in the survival group and 63 patients in the death group. Compared with the survival group, the APACHE Ⅱscore and the SOFA score of the death group were increased significantly (APACHE Ⅱ score: 20.29±5.90 vs. 15.32±5.98, SOFA score: 7.62±3.11 vs. 5.16±2.50, both P < 0.01), however, serum C3, C4 and cholesterol levels were obviously decreased [C3 (g/L): 0.67±0.22 vs. 0.82±0.24, C4 (g/L): 0.17±0.05 vs. 0.20±0.06, cholesterol (mmol/L): 2.77±1.23 vs. 3.46±1.02, all P < 0.01]. ROC curve analyses showed: each of the following items, complement C3, C4, and cholesterol, alone predicting the prognosis of sepsis patients, the area under ROC curve (AUC) and 95% confidence interval (95%CI) were as follows: AUC = 0.680 (95%CI = 0.583-0.777, P = 0.001), AUC =0.657 (95%CI = 0.560-0.754, P = 0.003), and AUC = 0.711 (95%CI = 0.619-0.804, P < 0.001) respectively; when complement C3, C4 and cholesterol combination to predict the prognosis of patients with sepsis, the resulting predictive value was better than the predictive value results obtained by each one of the items or each combination of any two of them (the AUC of C3+C4+cholesterol was 0.725, 95%CI = 0.633-0.817, P < 0.001; the AUC of C3+C4 was 0.697,95%CI = 0.603-0.791, P < 0.001; the AUC of C3 + cholesterol was 0.718, 95%CI = 0.626-0.811, P < 0.001; the AUC of C4+cholesterol was 0.722, 95%CI = 0.629-0.815, P < 0.001). Conclusion Using combination of serum complement C3, C4 and cholesterol levels to predict the prognosis of patients with sepsis may obtain important predicting value, that can provide a reference to clinical doctors.
