Objective:To evaluate the impact of laparotomy pancreatoduodenectomy (OPD), laparoscopic pancreatoduodenectomy (LPD) and Da Vinci robot assisted pancreatoduodenectomy (RPD) on the risk of pancreatic fistula in postoperative patients.Methods:The key words were laparoscopic, pancreaticoduodenectomy, robot, DaVinci, Whipple, complication, fistula, pancreaticoduodenectomy, laparoscopy, robot, postoperative complications and pancreatic fistula, and the databases of CNKI, Wanfang, VIP, CBM, Cochrane Library, PubMed, EMBASE and web of science were searched until August 1, 2020 for retrospective cohort studies and randomized controlled trials comparing the efficacy of OPD, LPD and RPD. The articles were screened according to the pre-set inclusion and exclusion criteria, and the quality of the articles was evaluated and the data were extracted. Based on Bayesian framework, R4.0.2, Revman 5.3 and Stata 16.0 software were used to analyze the extracted data for mesh meta analysis.Results:Thirty articles involving 3 428 patients were included, including 26 retrospective cohort studies and 4 randomized controlled studies. Mesh meta-analysis showed that in the incidence of pancreatic fistula, there was no significant difference between LPD and OPD, between LPD and RPD ( OR=0.93, 95% CI 0.63-1.4; OR=1.4, 95% CI 0.87-2.2, P<0.05), but the incidence of postoperative pancreatic fistula was significantly lower than that of OPD ( OR=1.5, 95% CI 1.1-2.1, P<0.05), 95% CI 1.12.1; P>0.05). The risk probability of pancreatic fistula was ranked as RPD (0.00), LPD(0.34) and OPD(0.65), that is, for the risk of postoperative pancreatic fistula, the advantages and disadvantages of the three surgical methods were ranked as RPD, LPD and OPD. Conclusions:Compared with OPD, RPD can significantly reduce the risk of pancreatic fistula after PD and improve the quality of operation; there was no significant difference between LPD and RPD in the incidence of postoperative pancreatic fistula, and both of them were safe and feasible.

Atherosclerosis is a complex disease characterized by lipid accumulation in the vascular wall and influenced by multiple genetic and environmental factors. To understand the mechanisms of molecular regulation related to atherosclerosis better, a protein interaction network was constructed in the present study. Genes were collected in nucleotide database and interactions were downloaded from Biomolecular Object Network Database (BOND). The interactional data were imported into the software Cytoscape to construct the interaction network, and then the degree characteristics of the network were analyzed for Hub proteins. Statistical significance pathways and diseases were figured out by inputting Hub proteins to KOBAS2. 0. The complete pathway network related to atherosclerosis was constructed. The results identified a series of key genes related to atherosclerosis, which would be the potential promising drug targets for effective prevention.
