Objective:To discuss the feasibility and value of open treatment for small and middle abdominal incision hernia repair.Methods:Retrospective analysis of 110 patients with abdominal wall incision hernia repair in our hospital from January 2016 to January 2018. They were divided into two groups according to the different operation, including open treatment group ( n=57)and laparoscopic treatment group ( n=53), the VAS efficacy scores, anal exhaust time, defecating time, removal of gastric tube time, removal of drainage tube time, first feed time, postoperative hospital stay time, hospitalization expenses were observed and analyzed respectively, measurement date with normal distribution were expressed as ( Mean± SD), comparisons between groups were analyzed using t test. Comparisons of count date between groups were analyzed using chi-square test. Results:All the patients were discharged, the VAS efficacy scores in open treatment about one day or three day and five day were (4.02±0.19), (2.21±0.26), (1.39±0.98) scores, the VAS efficacy scores in laparoscopic treatment were (4.68±0.62), (2.76±1.18), (1.84±0.62) scores, there were differences in complications between the two groups( P<0.05). The anal exhaust time, defecating time, removal of gastric tube time, removal of drainage tube time, first feed time of open treatment group were (50.73±14.69) h, (87.21±13.75) h, (9.64±3.92) h, (3.42±1.22) d, (37.11±9.76) h, and the laparoscopic treatment group were (65.14±9.54) h, (89.73±11.56) h, (11.43±5.61) h, (2.81±1.39) d, (38.92±7.59) h, there were differences complications between the two groups( P<0.05). The postoperative hospital stay time of open treatment group were (9.14±0.03) d, the postoperative hospital stay time of laparoscopic treatment group were (9.74±0.49) d, there were not differences in complications between the two groups( P<0.05). The hospitalization expenses in open treatment group were (1.51±0.36) ten thousand yuan, the hospitalization expenses in laparoscopic treatment group were(2.13±1.06) ten thousand yuan, there were differencesin complications between the two groups( P<0.05). Conclusion:Application of open treatment is feasible and effeetive for small and middle abdominal wall incision hernia.

Objective To investigate the association between phage-mediated shiga toxin and molecular distribution of CRISPR in Escherichia (E.) coli O26:H11 or NM.Methods A total of 135 E.coli O26:H11 or NM strains were collected from NCBI database.Software CRT and CRISPR Finder were used to extract CRISPR and Excel was used to assign the spacer of unique number and type CRISPR.And the relationship between CRISPR and stx phage was analyzed.Results All the 135 E.coli O26:H11 or NM strains had the CRISPR.For CRISPRI,CRISPR2.1,CRISPR2.2 and CRISPR3-4,19,22,1 and 1 subtypes were found,respectively.According to the four CRISPR sites,the strains could be divided into 40 subtypes.Stx-phage was only observed in the group C of CRISPR.Compared with E.coli of stx-phage negative,E.coli with stx-phage harbored more spacers.Conclusions CRISPR loci was extensively existed in E.coli O26:H11 or NM,and many subtypes were found in these strains.The presence of stx-phage was related to the molecular distribution of CRISPR in E.coli O26:H11 or NM.CRISPR might be a valuable biomarker to identify strains with high virulent potential.
