ABSTRACT
@#Objective To compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT). Methods PubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software. Results A total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01), time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5). Conclusion Compared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
ABSTRACT
Objective To learn whether plasmodium genetic attenuated sporozoites (GAS) can induce immunity against lung cancer ,in order to provide new ideas for the study of lung cancer vaccine .Methods Ther study was divided into two groups respec‐tively ,experimental group received intravenous injection of genetically attenuated sporozoites to immunize C57BL/6J mice and con‐trol group injection of phosphate buffer solution (PBS);after 14 days ,we subcutaneously inoculated lewis lung cancer (LLC) cells , calipers was used to measure tumor size .Immunohistochemical staining was detected tumor proliferation ,apoptosis ,and angiogene‐sis .Results There was statistically significant in tumor size .Immunohistochemical staining revealed that attenuated sporozoites in‐fection inhibited LLC eslls proliferation ,angiogenesis ,apoptosis .Conclusion The malaria attenuated sporozoites may provide a no‐vel strategy or therapeutic vaccine vector for anti‐lung cancer immune‐based therapy .
ABSTRACT
Objective To evaluate the influence of patellar resurfacing and non-patellar resurfacing on the effect of total knee arthroplasty to provide the evidence-based basis for selecting the clinical treatment scheme.Methods The clinical randomized controlled trials(RCT)on the whether having patellar replacement in total knee arthroplasty were retrieved from the databases of Pubmed,Cochrane,Medline,Embase,CNKI and WanFang data.The screening was independently performed by two researchers according to the including and excluding criterion.The related data were extracted.The reoperation rate,knee joint pain score and knee joint score served as the measurement criteria.The RevMan 5.2 software was adopted to conduct the meta analysis.Results Fifteen literatures were included to analyze,involving 1 788 patients,among them 871 cases were in the patellar resurfacing group and 917 case sin the non-patellar resurfacing group.The reoperation rate in the patellar resurfacing group was significantly lower than that in the non-patellar resurfacing group(RR=0.50,95 ％CI:0.33-0.76;P =0.001),moreover the knee joint function was significantly improved(WMD=3.04,95％CI:0.41-5.67;P=0.02).However,the anterior knee joint pain(WMD=0.96,95％CI:-0.85-2.76;P=0.30)and knee joint score(RR=0.81,95 ％ CI:0.50-1.32;P =0.41) had no statistical difference between the two operation modes.Conclusion Conducting patellar resurfacing in total knee arthroplasty can reduce the reoperation risk and improves the postoperative knee joint function,but does not improve postoperative knee joint pain score and knee joint score
