Chinese Journal of Emergency Medicine 2008;17(7):735-737
Objective To investigate the relationship between the colloid osmotic pressure (COP) as well asosmolality and the outcomes of critical patients. Method Totally 1568 critical patients were chosen from emergen-cy intensive care unit and surgical intensive care unit in Chaoyang Hospital Affiliated to Capital Medical Universityfrom January 2002 to December 2005, and divided into different groups according to levels of COP and osmolality.In group program Ⅰ, all patients were divided into 2 subgroups based on COP (the critical value was 20 mmHg =1.2 mOsm/kg H2O)on the day of admission. In group program Ⅱ, the same patients were divided into 3 sub-groups based on osmolality (the critical value was in the range from 280 mOsm/kg H2O aad 310 mOsm/kgH2O)which was also measured on the day of admission. The mortality of patients was calculated. Chi-square test wasused. Results Compared with patients of normal colloid osmotic pressure group, patients of lower colloid osmoticpressure group had higher mortality(24.5% vs. 17.7%, P = 0.001). Compared with the patients of normal os-molality group, the patients of lower total osmotic pressure group had lower mortality(17.0% vs. 24.5%, P =0.000). Conclusions Compared with the normal osmolality, the normal colloid osmotic pressure had the moreclosely relationship with the outcomes of critical patients, and it maybe a predictor of prognosis of the critical pa-tients.

Chinese Journal of Emergency Medicine 2009;18(2):140-143
Objective To investigate the therapeutic effects of injectio xuebijing (Chinese herb prepara-tions) on coagulat factors in dogs with septic shock. Method Eighteen dogs infected and shocked by intravenous endotoxin(LPS) were randomly divided into three groups: control group (n=6) treated with sodium chloride, dopamine group (n=6) treated with dopanfine, and dopamine plus xuebijing group (n=6) treated with dopamine and xuebijing. The therapeutic effects were assessed by comparison of the changes in VCAM (vascular cell adhe-sion molecule) ,ICAM (inter-cell adhesion molecule), VWF (yon willibrand factor) and PAI-I (plasminogen acti-vator inhibitor-1) at different indexes including the basic status, the dog being shocked without therapy, 3 and 7 hours after treatment.Analysis was made by SPSS 13.0 software. Results In xuebijing group, VCAM, ICAM, VWF and PAI-1 were signifieanfly changed 3 or 7 hours later after xuebijing administered rather than in control group and dopamine group (P<0.01 or P<0.05 ).In dopamine group, ICAM,VWF and PAI-1 were signiti-eanfly changed 3 or 7 hours after dopamine given rather than in control group (P<0.01 or P <0.05). Conclu-sions Injectio xuebijing obviously decreases the levels of coagulat factors in dogs with septic shock. Therfore, the injectio xuebijing can be used to treat the septic shock.

Chinese Journal of Emergency Medicine 2012;21(4):411-414
ObjectiveTo explore the prognosis and relationship between soluble differentiation antigen of cluster designation 14 (sCD14) and the injury severity score (ISS) of casualties with multiple injuries.Methods A total of 86 casualties with multiple injuries were enrolled from October 2009 to March 2010,and the severity of trauma of casualties were assessed in ISS score within the first 24 hours after accident,and the patients were divided into survival and non-survival groups as per the outcomes in 28 days after accident. Another 20 healthy subjects served as control group. In multiple injuries group,sCD14 concentrations were detected and APACHE Ⅱ scores were calculated on the 1st,3rd,5th and 7th days after accident.The related coefficient between sCD14 and ISS was calculated and then the values of sCD14 in predicting prognosis were analyzed by ROC curve. ResultsCompared with control group, sCD14 concentrations were obviously higher in casualties of multiple injuries group at all observation intervals ( P <0.01). Compared with survival group, casualties of non-survival group had more higher sCD14 concentrations and APACHE Ⅱ scores ( P < 0.05 ).The sCD14 concentration was correlated with ISS and the related coefficient was 0.469 ( P < 0.01 ). ROC curve analysis suggested sCD14 had values in predicting prognosis of casualties with multiple injuries and area under ROC curve was 0.820.Conclusions The concentration of sCD14 is correlated with ISS and can be used for predicting the prognosis of casualties with multiple injuries.
