Objective To explore the value of waring score of potential critical disease in predicting changes in condition of patients with multiple injuries. Methods From January 1, 2013 to July 31, 2013, all patients with multiple injuries were included prospectively. Patients were observed as soon as ICU admission. The waring score of potential critical disease and MEWS of all patients and the rates of changes in condition of patients were calculated then statistic analysis was performed. Results Of 50 patients enrolled, 44 were survived and 6 were died and 295 changes were found. The maximum , minimum median (P25, P75) of waring score of potential critical disease were 22, 0, 5 (3, 7). The maximum, minimum median (P25, P75) of MEWS were 12, 0, 4 (2, 6). The area under the ROC of waring score of potential critical disease was 0.880 (95% CI, 0.813-0.947, P < 0.001). Youden index was the biggest when waring score of potential critical disease was 6.5. The area under the ROC of MEWS was 0.767 (95% CI, 0.661-0.873, P < 0.001). Youden index was the biggest when MEWS was 5.5. Conclusion The waring score of potential critical disease was effective to predict changes in conditions of patients with multiple injuries and better than MEWS.

Objective To explore the application value of pulse induced contour cardiac output (PiCCO) monitoring in diagnosis and treatment of patients with neurogenic pulmonary edema (NPE).Methods With review of literature, the data of 4 patients of severe neurological disease complicated by NPE admitted into Department of Critical Care Medicine of Huangshan People's Hospital Affiliated to Wannan Medical College from 2011 to 2013 were retrospectively analyzed and discussed in their PiCCO hemodynamic characteristics and processes of treatment.Results The PiCCO of 4 patients with NPE showed that the extravascular lung water index (EVLWI) was increased significantly (EVLWI was 12 - 42 mL/kg on admission and 10 - 22 mL/kg after hospitalization for 24 hours), all revealing a high permeability pulmonary edema type. The capacity balance of the first 24 hours in the 4 cases was all of positive balance (+1 130, +1 200, +1 750, +1 120 mL respectively). In the treatment, the supplementary colloid was strengthened, the vasoactive drugs such as, dopamine, dobutamine, milrinone, etc were applied to improve the circulatory oxygenation, then the EVLWI was declined; finally the disease situation in 3 cases was improved and one died.Conclusions The clinical diagnosis and treatment of NPE is complex, and many contradictions appear in the therapeutic course. PiCCO monitoring is valuable in early diagnosis, identification of pulmonary edema type, guidance in fluid supplement and vascular active drug application, and assessment of disease severity and prognosis.

ObjectiveTo explore the risk factors of the occurrence of acute kidney injury (AKI) in critically ill patients, and to investigate the effect of hydroxyethyl starch (HES) on renal function in these patients.Methods A prospective investigation was conducted. Critically ill patients admitted to Department of Critical Care Medicine of People's Hospital of Huangshan, Wannan Medical College from March 2012 to October 2013 were enrolled. For all the patients under observation, the following data were collected: demography, comorbidities, clinical presentation, severity of illness, and the use of blood product and drugs. All patients were divided into AKI group and non-AKI group by means of Acute Kidney Injury Network (AKIN) criteria, then the risk factors of AKI were investigated by means of univariate and multivariate logistic regression analysis. The effect of HES 130/0.4 administration on renal function in critically ill patients was evaluated.Results 314 patients were enrolled for study out of 1 152 patients admitted. Among these patients enrolled, 89 of them were found to suffer from AKI. AKI was classified as stage 1 in 59 patients, stage 2 in 19 patients, and stage 3 in 11 patients. It was shown by the univariate analysis that 12 variables were the risk factors of AKI, including age, hypertension, diabetes mellitus, acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score, coagulation SOFA score, neurological SOFA score, cardiovascular SOFA score, blood pH on intensive care unit (ICU) admission, blood glucose on ICU admission, accumulating dose of HES, and presence of shock (P< 0.05 orP< 0.01). However, HES administration and daily maximum dose of HES were not the risk factors of AKI in critically ill patients (bothP> 0.05). Using the multivariate logistic regression analysis, it was shown that total SOFA score [odds ratio (OR) = 1.20, 95% confidence interval (95%CI) = 1.09-1.32,P< 0.001], hypertension (OR = 2.44, 95%CI = 1.22-4.89,P= 0.012), blood glucose level on ICU admission (OR= 1.85, 95%CI = 1.32-2.59,P< 0.001), and presence of shock (OR = 3.81, 95%CI = 1.93-7.53,P< 0.001) were independent predictors of AKI in critically ill patients, however, the cumulative dose of HES was not independent risk factor for AKI (OR = 0.77, 95%CI = 0.68-0.87,P< 0.001).Conclusions Total SOFA score, hypertension, blood glucose level on ICU admission, and presence of shock were independent risk factors for AKI in critically ill patients. HES administration may not be a causative factor of an increased risk of AKI in the ICU.

Objective To investigate the safety and efficacy of nephron-sparing surgery (NSS)for selective T2 stage renal tumor.Methods The surgical database of 26 patients treated with NSS for clinical T2 stage renal cell carcinomas between March 2010 and May 2013 were collected and analyzed retrospectively.There were 17 males and 9 females,with a mean age of 52 years (39-74 years),mean tumor size of 10.3 cm(7.2-16.5 cm),and mean R.E.N.A.L score of 7.5 (6-10).Patients'demographics,clinical characteristics,oncologic outcomes,renal function were reviewed.Results The renal masses were removed successfully and the surgical margins were negative.There were 21 (80.8％) cases of clear cell carcinoma,4 (15.4％) papillary carcinoma and 1 (3.8％) chromophobe carcinoma.The mean ischemia time was (28.3 ± 12.5) minutes (7 patients were clamp-free).Three patients needed transfusion,one experienced urine fistula and cured by conservative treatment,and one patient's renal function got progressive worsening and required long-term hemodialysis.The average serum creatinine was 121 μ mol/L before and 136 μmol/L after surgery (P =0.06).After a period of 22-47 months' follow-up,no patient had local recurrence or metastasis.Conclusions NSS can be safely performed and provide effective oncologic outcomes for selective patients with clinical T2 stage renal cell carcinomas.R.E.N.A.L nephrometry is an important factor and should be used to evaluate the feasibility of NSS.

Objective To explore the value of Oxford acute severity of illness score in evaluating the severity and prognosis of critical illness patients.Methods All adult patients admitted to the Department of Critical Care Medicine from August 2012 to July 2014 were retrospectively analyzed.The severity in survivors and non-survivors was evaluated by using Oxford acute severity of illness score and APACHE Ⅲ score,and then statistic analysis were performed.Results Of 470 patients,321 (68.297％) were male,the range of age and ((x) ±s) age were 18 to 97 years and (59 ± 18) years respectively,and 123 patients (26.170％) were in non-survivors group and 347 patients in survivors group.The area under the ROC of Oxford acute severity of illness score was 0.760 (95％ CI:0.712-0.808,P ＜ 0.001),and Youden index was biggest when Oxford acute severity of illness score was 30.5.The area under the ROC of APACHE Ⅲ score was 0.844 (95％ CI:0.806-0.882,P ＜ 0.01),and Youden index was biggest when APACHE Ⅲ score was 70.5.Mortality was high (above 70％) as Oxford acute severity of illness score increased (＞ 40),and Spearman r was 0.976 (P ＜ 0.01).Conclusions Oxford Acute Severity of Illness Score was useful to evaluating the severity and prognosis of critical illness patients and it was easy in clinical practice.

Objective: To analysis the expression level and clinical value of serum exosomal miR-744-5p in non-small cell lung cancer (NSCLC). Methods: Retrospective study. A total of 183 subjects, including 92 NSCLC patients and 91 healthy controls, were recruited from Nanfang Hospital Affiliated to Southern Medical University from November 2016 to February 2018. Exosomes were extracted using ExoQuick and the total RNA was extracted from the exosomes.The expression level of serum exosomal miR-744-5p was assessed by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR). The diagnostic efficiency of exosomal miR-744-5p was evaluated by receiver operating characteristic (ROC) curve. Results: The qRT-PCR results revealed that the expression level of serum exosomal miR-744-5p in patients with NSCLC (0.012 2±0.019 7) was significantly lower than that in the healthy control (0.093 6±0.081 9), and the difference was statistically significant (U=553.5, P<0.001). Furthermore, the level of miR-744-5p in patients with early stage (stage Ⅰ and Ⅱ) lung cancer(0.011 7±0.013 9) was significantly different, when compared to healthy controls (U=72.5, P<0.001). The exosomal level of miR-744-5p in samples (0.010 6±0.020 3) was lower than that in squamous cell carcinoma serum (0.017 3±0.017 8) , and the difference was statistically significant (U=394.5, P<0.001). The ROC curve revealed that miR-744-5p expression can be a significant biomarker to discriminate between normal and NSCLC cases, with an area under the ROC curve of 0.933 9 (95%CI=0.899 6-0.968 1, P<0.000 1). MiR-744-5p can effectively diagnose early stage NSCLC, with an area under the ROC curve of 0.943 1 (95%CI=0.883 7-1.000 0, P<0.000 1). Conclusion The serum exosomal miR-744-5p could serve as a non-invasive biomarker for the diagnosis of NSCLC, but further comparative research and expanded verification are needed.
