Objective To investigate the relationship between the serum levels of vascular endothelial growth factor(VEGF) and severity and prognosis by evaluating its changes in severe sepsis patients. Method Us-ing control study design, a total of 29 severe sepsis patients who admired in ICU department of Second Hospital of Tianjin Medical University from July 2006 to November 2007 were enrolled. The patients were divided into survival group (n=16) and death group (n=13) according to the clinical outcomes at 28 days after onset.A total of 31 healthy persons were enrolled into the control group. Clinical and laboratory data including blood routine test,blood-gas analysis,blood chemistry,C-reactive protein,lactic acid were collected on the first,third and 7th day after on-set,respectively. APACHE Ⅱ score were calculated. VEGF levels were determined using ELISA method. Quantita-tive data were analyzed by Ftest. Results The VEGFlevels ofthe control groupwere (78.77±8.15) pg/mL, the VEGF levels of the survival group on the first,third and 7th day were (210.47±59.40) pg/mL, (161.79 ±32.58) pg/mL and (85.33±12.13) pg/mL, respectively. The peak value of VEGF levels appeared on the first day, Then,it decreased with the progression of the disease. The VEGF levels did not differ significantly between the control group and survival group on the 7th day (P>0.05). The VEGF levels in the death group on the first, third and 7th day were (324.12±44.35) pg/mL,(185.40±30.92) pg/mLand (273.32±55.23) pg/mL, respectively. The peak value of VEGF levels in the death group also appeared on the first day, but it did not de-crease significandy on the 7 th day as compared that on theist day. The value of VEGF levels on the 7 th day were significantly higher than that of the control group (P<0.01 ). The levels of VEGF were positive correlated with APACHEⅡ score(rs = 0.510,P<0.01), both VEGF levels and APACHEⅡ score were risk factors for the clinical outcomes of these patients. Conclusions The serum levels of VEGF are elevated at early stage in severe sepsis patients. The VEGF levels, which might be a potential prognositic factor for sepsis patients are significantly correlated with APACHE Ⅱ score.

ObjectiveTo investigate the related factors of the occurrence of nosocomial infection and nursing management in operating room for general surgery patients,and provide a scientific basis to reduce the incidence of nosocomial infection of the operating room. Methods304 patients with nosocomial infection from August 2009 to August 2010 in our hospital for surgery were set as the control group.151 cases from September 2010 to October 2011 were named as the intervention group.All cases were analyzed retrospectively.The nursing factors which might affect nosocomial infection in operation room were analyzed by univariate and multivariate logistic regression analysis. ResultsBy univariate analysis,eight operation room nursing factors related to nosocomial infection were screened out:the type of incision,operation time,the following surgery or not,into ICU time,preoperative use of antibiotics,visitors of operations or not,invasive operation.5 highly correlated factors were screened out by multi-factor logistic regression analysis:admission to the ICU time,incision type,operation time,preoperative use of antibiotics,then following surgery.The infection rate and prolapse rate of the control group were significantly higher than those of the intervention group. ConclusionsIn nursing work of the operation room,we can take a series of nursing management interventions to reduce the incidence of nosocomial infection of general surgery.
