METHODS： The PubMed, Embase, Web of Science, Cochrane, SionMed, ClinicalTrials.gov, CNKI databases and Wanfang databases, published until Oct. 2017, were searched to identify studies comparing the clinical outcomes following vitrectomy with and without ILM peeling, for treating DME. Pooled results were expressed as odds ratios（ORs） with corresponding 95% confidence intervals（CI） for vitrectomy with and without ILM peeling with regard to best corrected visual acuity（BCVA）, central macular thickness（CMT）, and complication incidents. RESULTS： A total of 14 studies involving 857 eyes were included of which three studies were Chinese and the rests were English literatures. Meta-analysis indicated that compared with vitrectomy alone, vitrectomy with ILM peeling could improve BCVA more obviously（OR=1.66, 95%CI： 1.12-2.46, P=0.01） and had higher rate of CMT reduction（OR=3.89, 95%CI： 1.37-11.11, P=0.01）. There were significant statistical differences between the two surgical methods for both BCVA and CMT（P〈0.05）. For the incidence of intraoperative and postoperative complications, the incidence of epiretinal membrane（ERM） was slightly lower in the ILM peeling group than the group without ILM peeling（OR=0.38, 95%CI： 0.07-2.00, P=0.25）, although insignificant statistically. Other incidences of overall complications, iatrogenic peripheral retinal break and increased intraocular pressure indicated no significant difference between two groups（OR=1.19, 95%CI： 0.82-1.73, P=0.36; OR=1.21, 95%CI： 0.66-2.21, P=0.53; OR=1.34, 95%CI： 0.75-2.40, P=0.32）. CONCLUSION： Vitrectomy is effective for DME and the effect can be improved by additional ILM peeling, especially for anatomical efficacy, without increasing the incidence of intraoperative and postoperative complications. However, it is imperative to gain more evaluation in the future due to the paucity of prospective randomized study.展开更多

METHODS: A search was conducted using Pub Med, EMBASE, and CENTRAL(Cochrane Central Register of Controlled Trials) for related studies published before October 2018. RESULTS: A total of 29 studies and 2514 eyes were included in this network Meta-analysis. For IMH closure, the rank from the best to the worse treatment was: BBG, TB, TA, ICG, and no dye. There was a significant difference in postoperative IMH closure rate between BBG and no dye. The rank of the best to the worse treatment to improve visual acuity was: BBG, TB, no dye, TA, and ICG. The improvement rate of visual acuity after using BBG was significantly higher than ICG. The improvement rate of visual acuity was more favorable with TB than ICG, TA, and no dye. CONCLUSION: BBG can contribute to better anatomical and functional outcomes compared to other dyes for ILM peeling in patients with IMH. The results show that the best treatment of ILM peeling with dyes is BBG.展开更多

文摘BACKGROUND Controversy remains around the available choices for the internal fixation of a femoral neck fracture.The femoral neck system(FNS)was developed in 2018 and has been widely applied since then as it can provide rigid fixation stability with less damage to the bone mass around the fracture.However,no systematic reviews and meta-analyses have investigated the efficacy of the FNS in comparison with that of traditional internal fixation in the treatment of femoral fractures.AIM To assess the efficacy of the FNS in comparison with that of cannulated compression screws(CCS)in the treatment of femoral fractures through systematic review and meta-analysis.METHODS Five electronic databases(PubMed,Embase,Cochrane Central Register of Controlled Trials,China National Knowledge Infrastructure,and Wanfang)were searched from the earliest publication date to December 31,2021.Reference Citation Analysis(https://www.referencecitationanalysis.com/)was used to check the results and further analyze the related articles.Controlled trials were included if the FNS was applied for the femoral neck fracture in adults and if it was compared with CCS for the achievement of internal fixation.The measurement outcomes included the required operation time,observed patient’s blood loss,extent of fracture healing,patient’s Harris Hip score(HHS)at the last follow-up,and records of any complications(such as failure of internal fixation,femoral neck shortness,avascular necrosis of the femoral head,and delayed union or nonunion).RESULTS Ten retrospective controlled studies(involving 711 participants)were included in this metaanalysis.The meta-analysis showed that compared with CCS,use of the FNS could not decrease the operation time[standardized mean difference(SMD):-0.38,95%confidence interval(CI):-0.98 to 0.22,P=0.21,I2=93%),but it could increase the intraoperative blood loss(SMD:0.59,95%CI:0.15 to 1.03,P=0.009,I2=81%).The pooled results also showed that compared with CCS,the FNS could better promote fracture healing(SMD:-0.97,95%CI:-1.65 to-0.30,P=0.005,I2=91%),improve the HHS at the last follow-up(SMD:0.76,95%CI:0.31 to 1.21,P=0.0009,I2=84%),and reduce the chances of developing femoral neck shortness(OR:0.29,95%CI:0.14 to 0.61,P=0.001,I2=0%)and delayed union or nonunion(OR:0.47,95%CI:0.30 to 0.73,P=0.001;I2=0%)in adult patients with femoral neck fractures.However,there was no statistically significant difference between the FNS and CCS in terms of failure of internal fixation(OR:0.49,95%CI:0.23 to 1.06,P=0.07,I2=0%)and avascular necrosis of the femoral head(OR:0.46,95%CI:0.20 to 1.10,P=0.08,I2=0%).CONCLUSION Compared with CCS,the FNS could decrease the chances of developing femoral neck shortness and delayed union or nonunion in adults with femoral neck fractures.Simultaneously,it could accelerate fracture healing and improve the HHS in these patients.
