Objective To investgate the expression and the clinical significance of survivin in the primary hepatocellular carcinoma (HCC). Methods S-P immunohistochemical staining was performed to detect the expression of survivin in 50 samples of HCC tissue and 20 of normal liver tissue. Results The positive rate of survivin expression in HCC was 66. 0% (33/50) , which was significantly higher than that in normol liver tissues (negative expression) (P<0. 001). The expression of survivin was correlated with intrahepatic dissemination and multiple masses (P = 0. 019, P=0. 030). The high survivin expression was associated with the survival time less than three years(P = 0. 018). Conclusion The survivin may play certain roles in the oncogenesis and progression of HCC. Detection of the survivin can supply certain evidence on prognosis of primary hepatocellular carcinoma.

Forty-five patients with peritonsillar abscesses(PA) were treated by needle aspiration. Pus was drawn in 89%(40/45) of the cases at the first aspiration and repeated aspiration was necessary in 33%(15/45) of the patients. All of the patients were cured by needle aspiration without further invasive therapy and no serious complication was observed. 32 out of 45 patients were available for follow-up. Among them, three had another recurrent PA in situ and the other ten(31%) had recurrent tonsillitis. However, analysis showed that the patients under 35 years of age had higher recurreuce rate of PA of recurrent tonsillitis than those over 35 years old(P

Objective To evaluate the feasibility of developing hospital acquired pneumonia (HAP) risk warning model in critically ill patients based on genomic copy number polymorphisms (CNPs) of the genes encoding human neutrophil peptides 1-3 (DEFA1/DEFA3).Methods Seventy-seven HAP patients (group HAP) and 109 non-HAP patients of matched age and sex in intensive care unit (ICU) (group NHAP) were enrolled in the study.The genomic CNPs of DEFA1/DEFA3 was determined by realtime quantitative polymerase chain reaction after extracting DNA from peripheral blood samples.The source of patients,condition of endotracheal intubation within 24 h after admission to ICU,Acute Physiology Score,Acute Physiology and Chronic Health Evaluation Ⅱ score,Sequential Organ Failure Assessment score,mechanical ventilation time,length of hospital and ICU stay and outcomes were obtained.The predictive model was developed using logistic regression through combining DEFA1/DEFA3 copy numbers and clinical characteristics (Acute Physiology Score and source of emergency) within 24 h after admission to ICU.The receiver operating characteristic curve was used to evaluate the predictive efficacy of the model.Results The copy numbers of DEFA1/DEFA3 were significantly lower in HAP group than in NHAP group (P ＜0.05).The area under the receiver operating characteristic curve of the predictive model developed through combining the DEFA1/DEFA3 copy numbers with clinical characteristics was 0.789 (95％ CI 0.724-0.854) when the model was used for predicting HAP.Conclusion CNPs of DEFA1/DEFA3 can be used to develop the HAP risk warning model in critically ill patients.
