objective To detect MRSE and resistance in staphylococcus epidermidis isolates. Methods MRSE isolates were detected by cefoxitin disk test and susceptibilities were tested by agar dilution method. Results 79.7% of 128 isolates were MRSE strains with resistance to most antimicrobial agents, but those isolates were still susceptible to vancomycin and teicoplanin. Resistant rate in MRSE was higher than that in MSSE to most antimicrobial agents except penicillins, glycopeptides and macrolides. Conclusion MRSE with multi-resistance ale highly prevalent in staphylococcus epidermidis isolates and no isolate is resistant to glycopeptides.

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.
