ABSTRACT
To evaluate the feasibility and safety of suprapubic three-arm robot-assisted laparoscopic radical prostatectomy (STA-RLRP). Fifteen patients with prostatic cancer underwent STA-RLRP. All the 15 procedures were completed successfully, without the need for ancillary trocars or additional instruments. No patient required conversion to standard laparoscopy or open surgery. STA-RLRP is feasible and safe with good short-term tumor control, satisfactory recovery of urinary control function and good cosmetic outcome, which is worthy of clinical application.
ABSTRACT
Objective To analyze drug resistance data of Enterococcus faecalis and Enterococcus faecium,submitted by member units of Chongqing bacterial drug resistance monitoring network,and to provide the basis for our city effective application of antimicrobial agents and the reference.Methods Target bacteria identification and drug susceptibility test were performed by member units,according to the national technology scheme of bacterial drug resistance monitoring network and the results were determined according to standards published by Clinic and Laboratory Standard Institute(CLSI) in 2015.WHONET5.6 software was used to analyze drug susceptibility,and drug resistance difference was analyzed by using SPSS21.0 software.Results A total of un-repeated 1 811 strains of Enterococcus faecalis and 1 601 strains of Enterococcus faecium,accounting for 13.1% of all positive strains.The resistant rates of the two kinds of bacteria to vancomycin were 0.5% and 1.8%,to rinathiazole amine were 2.5% and 0.5% respectively.Tigecycline resistant strains were not founded.The resistant rate of Enterococcus feaclis to ouinupristin/dalfopristin was 90.1%,to tetracycline was 78.8%,to high concentration of gentamicin was 43.0%,to penicillin,ampicillin and nitrofurantoin was less than 7%.Except ouinupristin/dalfopristin and tetracycline,the resistant rate of Enterococcus faecium to the other drugs were significantly higher than Enterococcus faecalis(P<0.05).Strains isolated from children and adult patients,Intensive Care Unit(ICU) and un-ICU patients were with differences of drug resistance(P<0.05).Conclusion Most of Enterococcus infection could be caused by Enterococcus faecalis and Enterococcus faecium.Monitoring of drug resistance might be helpful for rational and effective usage of antimicrobial agents.
ABSTRACT
Bladder tissue engineering includes three components, namely cell scaffold, seeding cells and message factor. Seeding cells is essential to construct tissue engineering organs and is the native material of organ reconstruction. It is important to find a seeding cell which can not only provide excellent biocompatibility, but also can generate enough cells in work of organ reconstruction. At present, there are some commonly used seeding cells, for example, urinary bladder transitional epithelial cells,smooth muscle cells, coculture of smooth muscle cells and transitional epithelial cells, mesenchymal stem cells. Among the total,coculture of smooth muscle cells and transitional epithelial cells and mesenchymal stern cells are better than the others. The current problems of seeding cells are as follows: ①The mature cells that have been completely differentiated are limited in source and immunological rejection. ② The mature cells that have been completely differentiated during the differentiated only can generate in the limited passage culture procedure and they will age and die out of the passage maximum; in addition, the dedifferentiation also exists; ③further analysis should focus on the coculture of smooth muscle cells and transitional epithelial cells and mesenchymal stem cells into normal bladder.
