The benefits of early enteral nutrition (EEN) during critical illness have been widely accepted by global experts. To popularize this new concept and provide standardized, reasonable and effective EEN therapy for critically ill patients in China, more than 20 experts from throughout the country discussed and developed this consensus. We used the GRADE approach for consensus development, focusing on important clinical issues such as nutrition assessment, initiating mode, route selection and tolerance monitoring of EEN support therapy for current critically ill patients. This consensus would be certainly help for intensive care physicians in the clinical application of EEN support therapy for critically ill patients.

Objective To approach the effect of ulinastatin (UTI) on protection of vascular endothelial cells in rats with sepsis and its mechanism.Methods Fifty-two Sprague-Dawley (SD) male rats were randomly divided into a normal saline pretreatment group (control group) and a UTI pretreatment group (UTI group), each groupn = 26. The rats in two groups were given lipopolysaccharide (LPS, 10 mg/kg) intra-peritoneal injection for the establishment of rat septic models. In UTI group, 18 hours before LPS injection, intraperitoneal injection of UTI 100 kU/kg dissolved in 5 mL normal saline was given, while in the control group, 3 hours before LPS injection, intraperitoneal injection of 5 mL normal saline was given to the rats for pretreatment. Respectively, at 0.5, 2, 4, 12, 24, 72 hours after model establishment, tail venous blood and myocardial tissue were taken. The levels of tumor necrosis factor-α (TNF-α), interleukins (IL-6, IL-10), vascular cell adhesion molecule (VCAM) and intercellular adhesion molecule-1 (ICAM-1) were detected by enzyme-linked immunosorbent assay (ELISA); the correlation between TNF-α and ICAM-1 was analyzed; the expression of ICAM-1 in myocardial cell was determined by immunohistochemistry.Results After model establishment, the levels of TNF-α, IL-6, IL-10, ICAM and VCAM in two groups were gradually increased, reaching the peaks at 24, 12, 12, 72, 72 hours, respectively. Compared with control group, the levels of TNF-α, IL-6, ICAM-1, VCAM of UTI group were significantly lower at various time points [24 hours TNF-α (ng/L): 119.8±28.9 vs. 190.2±30.4, 12 hours IL-6 (ng/L): 327.8±26.9 vs. 948.7±63.8, 72 hours VCAM (ng/L): 36.3±3.2 vs. 68.8±2.4, 72 hours ICAM-1 (ng/L): 115.6±11.6 vs. 129.4±8.2,P < 0.05 orP < 0.01], IL-10 was significantly increased [12 hours (ng/L): 80.7±1.9 vs. 42.3±4.9,P < 0.01]. TNF-αwas positively correlated to ICAM significantly (UTI group:r = 0.907,P = 0.050; control group:r = 0.961, P = 0.010). Immunohistochemistry showed that after modeling for 0.5 hour, basically no positive expression of ICAM-1 in myocardial cells was found in the two groups; in the control group, at 12 hours the positive expression of ICAM-1 was increased, and in UTI group, a little expression of ICAM-1 was seen; at 72 hours, the expression of ICAM-1 was significantly increased in both groups.Conclusion UTI can protect the function of endothelial cells in rats with sepsis by regulating the expressions of proinflammatory cytokine, anti-inflammatory cytokine, adhesion molecules, and improving the microvascular permeability.

0.05) between two groups.After EGDT,the level of cTnI in EGDT group was obviously dowered on the 7th day (0.16?0.22?g/L) and 14th day (0.09?0.13?g/L) compared with those in control group (0.39?0.43,0.29?0.29?g/L,P

Objective To investigate the effects of ω-3 fish oil lipid emulsion via vein on the inflammatory response,immune and organ function in patients with severe acute pancreatitis.Methods A total of 53 patients with severe acute pancreatitis were randomized into conventional therapy plus fish oil group (FO group) and conventional therapy group (CON group).The patients in FO group were treat with ω-3 fish oil lipid emulsion (0.2 g · kg-1 · d-1,10％) based on conventional therapy for 14 days.The level of C-reactive protein (CRP),TG and TC were detected before treatment and at day 7 and day 14 after treatment.CD4+,CD4+/CD8+ and C3,C4 were also detected at day 1 and day 14 after treatment.At the same time,acute physiology and chronic health evaluation Ⅱ score (APACHE Ⅱ score),intra-abdominal pressure,negative fluid balance time,enteral nutrition start-time and ICU stay time were observed and recorded.Results Forty-five out of 53 patients were finally recruited into results statistics.The level of CD4+,CD4+/CD8+ and C3 at day 14 after treatment in FO groups improved significantly than that in the CON group (P ＜0.05).The levels of CRP,intra-abdominal pressure and APACHE Ⅱ score at day 7 and day 14in FO group descended more obviously than that in the CON group (P ＜ 0.05).The negative liquid balance time in FO group (3.55 ±0.86) days was obvious shorter than that in CON group (4.61 ± 1.12) days,while enteral nutrition start-time (3.86 ± 1.17) days was significantly earlier compared with CON group (5.30 ± 1.61) days (P ＜ 0.05),however ICU stay time and 28 days mortality rate had no significant difference between the two groups.Conclusions ω-3 fish oil lipid emulsion can decrease the inflammatory response and the negative liquid balance time,improve the immune function and restore bowel function in severe acute pancreatitis patients.Therefore,it maybe provide a new and effective means for severe acute pancreatitis.

Objective To evaluate the predictive value of brain natriuretic peptide (BNP) on mortality in elderly patient with severe sepsis or septic shock. Method Eighty-three elderly patients meeting with criteria of severe sepsis or septic shock by the American College of Chest Physicians and the Society of Critical Care Medicine (ACCP/SCCM) in 2001, admitted in Intensive Care Unit (ICU) of Zhejiang Hospital during May 2004 to June 2007, were enrolled, and patients with chronic renal failure were excluded. The patients were divided into survivor and non - survivor group according to whether they survived within 28 days staying in ICU, the difference of plasma BNP level,serum C-creative protein (CRP) concentration, APACHE II and SOFA scores on admission day and BNP level on the third day between the two groups were compared; thereafter, the relationship between muhiple variables including age, admission day, BNP, CRP, APACHE 11 and SOFA scores, the 3rd day BNP level and 28-day mortality were analyzed by Logistic regression, and meanwhile the independent predictors for ICU moaality among which were determined. Results BNP levels on both admission day and the 3rd day were significantly higher in nomurvivor group than those in survivor group[ ( 1056.38±676.34) pg/ml vs. (611.59±610.02) pg/ml,p =0.002 and (1448.48+891.11) pg/ml vs. (522.41±575.20) pg/ml, P<0.001, respectively]. By Logistic regression analysis, BNP level on the 3rd day and SOFA score on admission day were independent predictors of ICU mortality, The receiver operating characteristic (ROC) curves indicated that values of areas under the curve of the admission day and the 3rd day BNP levels for 28-days mortality were 0.735 (95% CI,0. 621～0. 848, P <0.001) andO.836 (95% CI, 0.746～0,926,P<0.001), respectively. Conclusions Plasma BNP inereaseds in majority of eldedy patients with severe sepsis or septic shock, which may serve as irdex for prognosis in elderly severe septic paients.

Objective To explore the significance of the plasma procalcitonin (PCT) level for directing antibiotic therapy in elderly patients with ventilator-associated pneumonia (VAP).Methods The 50 elderly patients with VAP were randomly separated into the regular therapy group and the PCT-directed therapy group. The regular therapy group was given regular antibiotic therapy, while the antibiotic therapy was decided according to the plasma level of PCT in the PCT-directed therapy group. The used time and utilization rate of antibiotics, as well as inflammatory indicators including white blood cells, neutrophils, C-reactive protein (CRP) and clinical pulmonary infection score (CPIS) were compared between the two groups. Results After treatment, there were no significant differences in white blood cells, neutrophils and CRP between the PCT-directed therapy group and regular therapy group [(8.9 ± 3.5 ) × 109/L vs. (9.4 ± 3.7) × 109/L, 0.62 ± 0.04 vs.0.60±0.04, (18.7±8.5) mg/Lvs. (21.6±6.0) mg/L, t=0.47, 1.84 and 1.37, allP＞0.05],but the CPIS was markedly lower in PCT-directed therapy group than in regular therapy group [(4.0± 1.4) scores vs. (4.7± 1.0) scores, t= 2. 18, P＜0.05]. The neutrophils, CRP and CPIS were significantly lower after treatment than before in the both groups. The concentration of PCT was decreased after treatment than before [(0.5 ± 0.9) mg/L vs. (1.7 ± 0.7) mg/L]. Meanwhile, the time using antibiotics was longer in regular treatment group than in PCT-directed therapy group [(8.72±1.32) d vs. (5.17±0.72) d, t=11.96, P＜0.01], the utilization rate of antibiotics was higher (95.2 % vs. 55.2 %, χ2 = 12.41, P＜0.01) in regular treatment group. Conclusions Using PCT levels for directing treatment in elderly patients with VAP can achieve better curative effect and reduce the use of antibiotics.

Objective To investigate whether early goal-directed therapy ( EGDT ) could lower the mortality rate in patients with severe sepsis and septic shock. Methods Articles with items sepsis, severe sepsis, septic shock, EGDT were retrieved from MEDLINE, EMBASE, Cochrane, Wanfang Data and CNKI. Inclusion criteria included randomized controlled trial, subjects concerning patients with severe sepsis or septic shock, endpoints with short-term mortality [ in-hospital, intensive care unit ( ICU ) or 28-day ] and long-term mortality ( 60-day or 90-day ). Related risk ( RR ) and 95% confidence interval ( 95%CI ) were used as indices to judge the difference in mortality rate between EGDT group and standard treatment group. RevMan 5.2 software was used for Meta analysis. Results There were 8 studies meeting inclusive criteria with a total of 4 853 patients. For patients with severe sepsis and septic shock, compared with the group with routine treatment, EGDT showed a decrease in the short-term mortality ( RR = 0.74, 95%CI=0.66-0.82, P<0.000 01 ), but did not decrease the long-term mortality ( RR=0.99, 95%CI=0.92-1.06, P=0.81 ). Conclusion EGDT strategy may decrease the short-term mortality in patients with severe sepsis and septic shock, but it showed no influence on the long-term mortality.

Objective To investigate the expression of inflammatory cytokines in patients with severe sepsis by using an antibody chip.Methods Twelve patients with severe sepsis and other 10 patients whose age and gender were matehed were enrolled in this study.Proteins from patients were labeled with biotin.The biotin-labeled proteins reaeted with antibody chips,on which there were antibodies of 40 major inflammatory cytokines.The target proteins were conjugated with streptomycin antibody labeled by horseradish peroxidase(HRP),and signals were imaged by laser scanner.Results In comparison with control group,the serum levels of inflammatory eytokines ineluding pro-and anti-inflammatory cytokines,ehemokines and certain eytokines receptors were notably increased,while expression of anti-inflammatory interleukin(IL)-2,-4,-13,-15 was remarkably decreased in sepsis group.Conclusions Excess inflammatory response and imbalance of pro-and anti-inflammatory eytokines were presented in the eourse of severe sepsis.
