Objective To perform APACHEⅡand SOFA in assessmentof EICU patients with sepsis ,and analyze the risk factors. Methods A retrospective analysis from January 2014 to October 2015 in EICU of our hos-pital ,a total of 83 patients suffered from sepsis ,including sepsis group(30 cases)and septic shock(53 cases). PCT,PT,APTT,lactic acid,mechanical ventilation time and APACHE Ⅱ and SOFA score were collected, through the receiver-operating characteristic curve(ROC)index to predict the prognosis of patients with sepsis.Re-sults The mortality of the patients in the septic shock group,PT,APTT,APACHEⅡ,SOFA score,mechanical ventilation time and PCT were significantly higher than thosein the sepsis group(P<0.001). APTT,APACHEⅡ, SOFA score and mechanical ventilation time had significant difference (P ≤ 0.001) between survival and dead. The lactic acid level of the dead group was significantly higher than that in the survival group(P=0.038). The ar-ea under curve(AUC=0.806)of APACHEⅡscore was better than the SOFA score(AUC=0.765).The outcome of sepsis had correlation with APACHEⅡ,SOFA score,lactic acid,and mechanical ventilation time(P<0.05). Conclusion APACHE II and SOFA scores can accurately predict mortalityoutcome in emergency intensive care units patients with sepsis,especially the APACHEⅡscore.We can measure blood coagulation function,APACHEⅡ,SOFA score,PCT,lactic acid and mechanical ventilation time to assess the severity of patients with sepsis.

Objective To investigate the change and effect of operation on TK1,CEA, SCC-Ag and CYFRA21-1 level in non-small cell lung cancer patients. Methods From January 2013 to August 2013, 55 patients with NSCLC and 29 patients with benign lesions were recruited. The tumor indexes including TK1,CEA, SCC-Ag and CYFRA21-1 were measured by electrical chemiluminescence assay. Results ① Serum TK1, CEA, SCC-Ag and CYFRA21-1 level and the positive rates in NSCLC patients during preoperative period were higher than the benign disease control group ( P<0. 05 ) . ② Serum TK1 level changes in NSCLC patients preoperative and postoperative one week and one month showed a trend of hump-shaped curve, there was no obvious statistically significant differ-ence ( P>0. 05 ) . Serum CEA , SCC-Ag and CYFRA21-1 level of postoperative one week and one month in NSCLC patients were significantly lower than the level before the operation ( P<0. 05 ) . Serum CEA and CYFRA21-1 level of postoperative one week and one month in NSCLC patients showed no significant difference compared with benign disease control group ( P>0. 05 ) , serum TK1 and SCC-Ag level of the postoperative one week showed statistically significant difference compared with benign disease control group ( P<0. 05 ) , the postoperative one month level of serum TK1 and SCC-Ag showed no significant difference compared with benign disease control group ( P>0. 05 ) .③The preoperative level of TK1 and CEA in adenocarcinoma were higher than that in squamous carcinoma ( P<0. 05 ) . ④ The preoperative level of serum TK1 and CYFRA21-1 in female NSCLC patients were higher than male patients, the difference was statistically significant ( P <0. 05 ) , preoperative serum CEA and SCC-Ag level of NSCLC patients showed no obvious statistical correlation with gender ( P>0. 05 ) . The preoperative level of serum TK1 in NSCLC patients negatively correlated with the degree of differentiation of lung cancer, the difference was statistically significant ( P<0. 05 ) . Conclusion The perioperative level of tumor markers in NSCLC may be useful in monitoring diagnosis and differential diagnosis of NSCLC, especially in analyzing the invisible tumor burden of NSCLC patients. The perioperative level of tumor markers in NSCLC is related with the surgical effect and tissue types, and serum TK1 and CEA are more suitable for the evaluation of patients with lung adenocarcinoma. There is some value in the clinical applications.

Objective To investigate whether p53 expression is involved in human telomerase reverse trans-criptase (hTERT) regulation. Methods HepG2 cells and pPUR/U6/hTERT HepG2 cells were treated with the p53 antisense oligonucleotide respectively and p53 expression plasmid were introduced to HepG2 cells. The decreased or increased p53 level and the hTERT expression levels were analyzed by Western blotting. Results Down-regulation of p53 expression had no obvious effect on hTERT expression, but over-expression of p53 could significantly repress hTERT level. Conclusion p53 interacts with hTERT and inhibits hTERT expression in HepG2 cells.
