Objective To determine the clinical indicators of early death (within 72 hours) in patients with acute paraquat poisoning.Methods The data of 93 acute paraquat poisoning patients admitted to emergency intensive care unit (EICU) of the First Hospital of China Medical University were retrospectively analyzed.The patients were divided into two groups according to whether they died within 72 hours or not.The gender,age,poison dose,paraquat concentration in urine,reduction of paraquat amount in urine after each hemoperfusion,and the worst value of white blood cell (WBC) count,lymphocytes count,arterial blood gas analysis,blood K +,Na+,Cl-,and serum amylase,serum lipase,serum total bilirubin,troponin Ⅰ,creatine kinase (CK),blood urea nitrogen,serum creatinine within 24 hours after poisoning were compared.Spearman correlation analysis was used to analyze the correlation between paraquat concentration in urine and the dose of paraquat.The predictive value of each indicator at death in early stage of poisoning was analyzed with receiver operating characteristic curve (ROC curve).Results Nineteen patients in the group of those died in early stage of poisoning (within 72 hours) resulted in a mortality rate of 20.4％.Compared with non-early death group,in early death group,the value of poison dose (mL:133.4 ± 108.8 vs.58.6 ± 40.0,t=3.145,P=0.002),paraquat concentration in urine [mg/L:16.34 (11.87,96.76) vs.4.46 (1.21,12.78),Z=-3.422,P=0.001],WBC (× 109/L:22.63 ±9.72 vs.14.95 ±8.39,t=3.446,P=0.001),blood lactate [Lac (mmol/L):6.7 (2.2,12.1) vs.1.9 (1.1,3.4),Z=-3.294,P=0.001] were significantly higher,and the reduction rate of paraquat concentration in urine after first perfusion [(38.4 ± 15.63)％ vs.(67.59 ± 27.87)％,t=2.945,P=0.004] and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg=0.133 kPa):28.7 ± 9.3 vs.34.8 ± 6.7,t=-3.245,P=0.002] were significantly lowered.There was no significant difference between two groups in other indexes.Poison dose and paraquat concentration in urine showed significantly positive correlation (r=0.450,P＜0.001).ROC curve showed that the predictive value of paraquat concentration in urine,WBC,and Lac in early death were significant [area under the ROC curve (AUC) of paraquat concentrations in urine was 0.806,95％ confidence interval (95％CI) 0.699-0.913,the cut-off value was 11.64 mg/L,with sensitivity 84.6％,specificity 71.4％; AUC of WBC was 0.734,95％CI 0.569-0.899,the cut-off value was 15.94 × 109/L with sensitivity 69.2％,specificity 76.8％ ; AUC of Lac was 0.729,95％CI 0.568-0.891,the cut-off value was 1.95 mmol/L with sensitivity 84.6％,specificity 42.9％].Conclusions Paraquat concentrations in urine,WBC,Lac,poison dose and PaCO2 were the risk factors of the early death of the acute paraquat poisoning.The research suggests that paraquat concentration in urine,WBC and Lac are valuable in predicting early death of the patients.

Objective:To establish a preoperative forecasting model for the nature of duodenal papillary tumors and to discuss its main predictors.Methods:A case-control study was conducted;the case group included patients with malignant duodenal papillary tumors and the control group included patients with benign duodenal papillary tumors.All the patients were from Changhai Hospital. Data of patients,including the demographic characteristics,clinical symptoms during onset,laboratory findings,and radiological data, were collected by face-to-face interviews or by reviewing the medical history.Chi-square,t-test or ANOVA were employed to performed univariate analysis.All factors with P values less than or equal to 0.25 in the univariate analysis were used as independent variables for multivariate analysis,and a Logistic regression forecasting model for the nature of duodenal papillary tumors was established.Results: Totally 199 patients with pathologically-confirmed duodenal papillary tumors were included in the present study,with 166 in the case group and 33 in the control group.Multivariate analysis showed that hemoglobin(Hb),total bilirubin(Tbil),direct bilirubin(Dbil), aspartate transferase(AST),alkaline phosphatase(AKP),gamma glutamyl transpeptidase(GGT),and carcinoembryonic antigen(CEA) were independent predictors for nature of duodenal papillary tumors,with their odds ratios(95% confidence interval)being 0.981 (0.959,1.003),0.867(0.794,0.948),1.207(1.075,1.355),1.028(1.008,1.048),0.996(0.992,1.000),1.002(1.000,1.004),and 0.974(0.953,0.994),respectively.Conclusion:The Logistic regression model,which takes into consideration of Hb,Tbil,Dbil,AST, AKP,GGT,and CEA,can be used to predict the nature of duodenal papillary tumors,and its clinical value need to be further studied.

Objective To compare the effect of enteral administration and intravenous infusion of hypertonic electrolyte glucose solution (HEGS) in the resuscitation of burn shock. Methods Fifteen beagle dogs with 35% TBSA third degree burn were used in present study, and divided into three groups randomly: noresuscitation group, intravenous infusion resuscitation group and enteral administration resuscitation group. For the animals in the latter two groups, 1.8% HEGS was administrated intravenously or enterally for resuscitation 30 min after burn. The volume of fluid infusion in the first 8h was 1ml/(kg?1% TBSA), and the transfusion velocity was equilibrated. The mean arterial pressure (MAP), cardiac index (CI), plasma volume (PV), and sodium concentration in plasma were obtained to evaluate the effect of resuscitation used HEGS. Results The MAP, CI and PV were similar in both enteral and intravenous groups, which were higher than those in noresuscitation group. In both enteral and intravenous groups, MAP was raised after burn and then lowered after resuscitation, meanwhile CI and PV were raised and then lowered after resuscitation, but there were no differences between the two groups. The sodium concentration in plasma was stable in the noresuscitation group and increased in enteral and intravenous groups, and it was higher in intravenous groups than in enteral group. Conclusion In the resuscitation of early shock of 35% TBSA three degree burns, the effect of 1.8% HEGS administrated enterally on CI, PV, MAP and sodium concentration in plasma was similar to that of intravenous infused.
