Objective To systematically review the efficacy of enteral nutrition with eicosapentaenoic acid ( EPA) , gamma-linolenicacid ( GLA) , and anti-oxidants for patients with sepsis. Methods We searched the PubMed, EMbase, Cochrane Library, Wanfang Database, CNKI and VIP for all randomized controlled trials about the efficacy of an enteral diet enriched with EPA, GLA, and anti-oxidants for patients with sepsis. The quality of the studies was evaluated by the method recommended by Cochrane Collaboration. Meta-analysis was conducted using the Cochrane Collaboration’s RevMan 5.0 software.Results Three RCTs involving 350 patients were included in our systematic review. The results showed a significant reduction in the length of ICU stay ( MD =6.21, 95% CI: 4.61-8.19; P lt;0.00001) and hospital stay ( P lt;0.0001) , a fewer development of neworgan dysfunctions in the patients fed with the study diet and no more adverse events were observed. However, no significant difference in 28-day mortality of all cause was revealed( RR=0.83, 95% CI: 0.60-1.16, P = 0.27) . There were controversial results about the duration of mechanical ventilation.Conclusion A diet enriched with EPA, GLA, and elevated antioxidants is safe and beneficial for the clinical outcome in patients with sepsis.
輸血相關性急性肺損傷（TRALI）是發生于輸血期間或輸血后的罕見并發癥，以急性缺氧和非心源性肺水腫為特點，因死亡率高（5%~10%）而越來越受到臨床關注[1]，據2004年美國食品藥品管理局（FDA）的數據，TRALI為輸血相關性死亡的首要因素[2]。根據文獻資料，輸注血制品、含血漿制品、新鮮冰凍血漿（FFP）和血小板的TRALI發生率分別約為1/5 000[3]，1/2 000[4]，1/7 900[5]和1/432[6]。據報道，所有血制品（除白蛋白外）均可引起TRALI[7]，甚至有作者懷疑大劑量給予白細胞介素-2（IL-2）也可能導致TRALI[8]。目前，我國有關TRALI的報道較少，僅有個別死亡案例報道[9，10]，而相關的研究報道很少，這可能與我們尚未認識到TRALI的危險性，以及對其的診斷率較低有關。
Objective To evaluate the diagnostic value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) for sepsis. Methods Such databases as The Cochrane Library (Issue 4, 2012), PubMed, EMbase, CBM, CNKI, VIP and WanFang Data were searched to collect the diagnostic tests on sTREM-1 for sepsis published before April 2012. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality. Then, Meta-Disc software (Version 1.5) was used to conduct analyses, draw the summary receiver operating characteristic (SROC) curve, and calculate the area under curve and Q index. Results A total of 11 studies involving 1 615 patients were included. The value of sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, area under of SROC curve, and Q index were 69%, 71%, 3.7, 0.34, 14.73, 0.875, and 0.805, respectively. Conclusion This meta-analysis shows that sTREM-1 as a single indicator has moderate accuracy for early diagnosing sepsis. It should be combined with other diagnostic indicators to further improve the sensitivity and accuracy in diagnosing sepsis.
