【Abstract】ObjectiveTo analyze the factors influencing the prognosis of patients with bile duct carcinoma after resection. MethodsThe clinical data of 120 patients with bile duct carcinoma receiving resection in our hospital from 1980 to 2004 were collected retrospectively and clinicopathologic factors that might influence survival were analysed. A multiple factor analysis was performed through Cox proportional hazard model. ResultsThe overall 1year, 3year and 5year survival rates were 71.7%, 32.5% and 19.2% respectively. The single factor analysis showed that the major significant factors influencing survival of these patients were histological type of the lesions, lymph node metastasis, pancreatic infiltration, duodenal infiltration, resected surgical margin, perineural infiltration, peripheral vascular infiltration and depth of tumor infiltration (P＜0.05). Lymph node metastasis, pancreatic infiltration and perineural infiltration were found to be the the statistically significant factors influencing survival by multiple factor analysis through the Cox model. ConclusionThe most important prognostic factors for bile duct carcinoma after resection were lymph node metastasis, pancreatic infiltration and perineural infiltration.
Objective To investigate the outcome and prognostic factors of hospital mortality in patients with acute cerebrovascular disease requiring mechanical ventilation.Methods Data from 94 patients with acute cerebrovascular disease in central intensive care unit(ICU) were collected and retrospectively analyzed.Prognostic factors of hospital mortality were analyzed by univariate statistics and multivariate logistic regression.Results Hospital mortality was 53.2%(50/94).There was significance diference in parameters such as APACHE II score，blood glucose，lengh of hospital stay，lengh of ICU stay，time of mechanical ventilation，incision of trachea，lung infections，lesion loci and its naturer between the survival and non-survival groups（all Plt;0.05）.Multivariate logistic regression revealed that blood glucose，lung infections，diseased region under tentorium of cerebellum，time of mechanical ventilation were independent prognostic risk factors of hospital mortality(all Plt;0.05).Whereas the lengh of ICU stay was protective factor(Plt;0.05).Conclusion The hospital mortality is considerably high in patients with acute cerebrovascular disease requiring mechanical ventilation. The prognostic factors such as blood glucose and lung infections should be evaluate cautiously and prevented aggressively.
Objective To study the risk factors and prognosis of hospital acquired pneumonia( HAP)caused by carbapenem-resistant Acinetobacter baumannii( CRAB) . Methods By a case-control study, the data of 44 cases of HAP caused by CRAB fromJan 2005 to Dec 2007 in Nanfang Hospital were analyzed. 66 cases of HAP caused by Carbapenem-susceptible A. baumannii ( CSAB) were selected randomly at the same time as control. Univariate analysis( T test and chi-square test) and multivariate logistic regression were used for statistics analysis. Results Univariate analysis revealed that five factors associated with the infection caused by CRAB were APACHE Ⅱ score ≥ 16, chronic pulmonary disease ( COPD/ bronchiectasis ) , imipenem/meropenem and fluoroquinolone used 15 days before isolation of CRAB, and early combination therapy of antibiotics. Multivariate logistic regression analysis identified two independent factors as APACHEⅡ score ≥16( OR=6. 41, 95% CI 2. 20-18. 67) and imipenem/meropenemused 15 days before isolation of CRAB( OR =6. 33,95% CI 1. 83-21. 87) . Of 44 cases of CRAB infections, 14 patients died and 30 patients survived. Univariate analysis revealed that two factors associated with poor prognosis were organ failure and clinical pulmonary infection score( CPIS) rise after three-day treatment. According to multivariate logistic regression analysis, only CPIS rise after three-day treatment ( OR =7. 01, 95% CI 1. 23-40. 03) was an independent predictive factor. Conclusions APACHEⅡ score ≥ 16 and imipenem/meropenem used 15 days before isolation of CRAB were independent risk factors for CRAB infection. CPIS rise after three-day treatment was a predictive factor for the prognosis of CRAB infection.
Objective To study the mortality and prognostic factors of post-operative acute respiratory failure in cancer patients. Methods There were 1632 postoperative cancer patients from2004 to 2006 in the ICU of Cancer Hospital, in which 447 patients were complicated with acute respiratory failure ( intubation or tracheotomy and mechanical ventilation) . The clinical data was retrospectively analyzed. Stepwise logistic regression analysis was used to identify variables associated with mortality for acute respiratory failure. Results In 447 patients with acute respiratory failure ( male 260, female 187) , 106 cases died with a mortality of 6. 5% . Single factor analysis showed that acute morbodities ( shock, infection, organ failure) , intervention ( continuous renal replacement therapy, vasopressor drugs) , the 28-day ICU free days and APACHE scores ( ≥ 20) had significant differences between the survivor and non-survivor. Multiple logistic regression analysis showed that duration of operation( P = 0. 008, OR 1. 032, 95% CI 1. 008-1. 057) , APACHEⅡ≥20 scores( P =0. 000, OR12. 200, 95% CI 2. 896-51. 406) , organ function failure( P =0. 000, OR 13. 344,95% CI 3. 791-7. 395) were associated with mortality of acute respiratory failure. Conclusion Duration of operation, organ function failure, and APACHE Ⅱ scores were risk prognostic factors for postoperative cancer patients with acute respiratory failure.
Objective To explore the distribution characteristics and prognostic risk factors of critically ill patients who has long-term hospitalization in intensive care unit ( ICU) . Methods A retrospective study was carried out to evaluate 119 critically ill patients from January 2003 to July 2009 by extracting data from computerized hospital information system. The patients were divided into a survival group and a non-survival group based on discharging outcomes. A binary logistic regression analysis wasintroduced to investigate potential risk factors of prognosis. Results Age, type of payment, entity of disease,and length of ICU stay were significantly different between the two groups ( P lt; 0. 05) in independent-Samples T test. Logistic regressions indicated that age, length of ICU stay and plasma infusion were independent predictors for worse outcome. Conclusions Age, length of ICU stay and plasma infusion may directly influence the prognosis of patients with prolonged stay in ICU. Intensive therapies should be emphasized for those patients at high risk.
Objective To investigate the prognostic factors and hospitalization cost in patients diagnosed as central line-associated bloodstream infection( CLABSI) in intensive care unit( ICU) .Methods A retrospective study was made to investigate the CLABSI epidemic data in ICU from June 2006 to June 2009. Clinical and physiological parameters were summarized and compared between these patients, which were divided into two groups based on the clinical outcome. Meanwhile, events including blood transfusion,mechanical ventilation, as well as cost of hospitalization were also reviewed. Logistic regression method was introduced to investigate the potential prognostic risk factors. Results There were 49 patients were diagnosed as nosocomial CLABSI, in which 19 cases( 38. 8% ) died in the hospital and 30( 61. 2% ) weresurvival. In univariate analysis, differences in body temperature, central venous pressure, acute physiology and chronic health evaluation( APACHEⅡ ) score, blood transfusion amount, pH value, D-dimer, blood serum alanine transarninase, blood urea nitrogen level, serumcreatinine, serumpotassiumbetween the survivors andthe non-survivors were significant( P lt;0. 05) . However, no significant differences were observed between the two groups in in-hospital days, ICU days and hospitalization cost ( all P gt; 0. 05) . With multiple logistic regressions, higher APACHEⅡ score( OR 0. 78; 95% confidence interval: 0. 66-0. 94; P = 0. 007) , APTTlevel( OR 0. 87; 95% confidence interval: 0. 77-0. 98; P = 0. 026) and serum potassium( OR 0. 09; 95% confidence interval: 0. 01-0. 80; P = 0. 031) were independent predictors of worse outcome. Conclusions Disease severity and coagulation situation may directly predict the prognosis of nosocomial CLABSI patients.But current investigation did not demonstrate significant differences in ICU length of stay and respective cost between the CLABSI patients with different prognosis.

Objective To evaluate the effectiveness and prognosis of patients in advanced hepatocellular carcinoma (HCC) with portal vein (PV) tumor thrombus received external-beam radiation therapy (EBRT). Methods The clinical data of 126 HCC patients with PV tumor thrombus who were referred for EBRT at our institution from January 2000 to November 2009 were analyzed retrospectively. EBRT was designed to focus on the tumor thrombus with or without primary intrahepatic tumors， to deliver a median total conventional dose of 50 Gy (range of 30-60 Gy). Predictors of survival were identified using univariate and multivariate analysis. Results Unfavorable pretreatment predictors were associated by multivariate analysis with lower albumin and higher α-fetoprotein levels, poorer Child-Pugh liver function classification, poorer intrahepatic tumor control， lymph node metastases， and the two-dimensional EBRT technique. The dose of EBRT showed no significant in both univariate and multivariate survival analysis. Conclusions In patients with HCC， EBRT is effectively prevents progression in cases of PV tumor thrombus， but palliative dose of EBRT is not related to survival.EBRT is not related to survival.
