ABSTRACT
Objective To explore the key initiatives and effective methods for preparing the constructions of emergency-oriented hospitals under COVID-19 pandemic. Methods The wartime mechanism was strengthened by adhering to unified leadership, trengthening the top-level design and clarifying the division of responsibilities. Objective management was used as a means to take into account the key of personnel allocation and training, prevention and control of hospital infection, transformation of contagious ward, logistic support, equipment and material supply and construction of system and process. Results The preparations and constructions of the emergency-oriented hospitals were completed in 72 hours，which passed the acceptance and inspections from infection control experts，who appraised our work to be “the highest in difficulty, the fastest in project progress and the highest in quality". Totally, upon to the preparations，14 medical teams were set up and the layout process reestablishment of 14 wards was completed, the installation and preparation of nearly 10000 sets/pieces of medical equipment and medical materials were completed as well and more than 80 work systems and process systems for 9 major modules were established. Conclusion The preparations and constructions of emergency-oriented hospitals should be performed upon the thorough implementation of the decisions and arrangements by the municipal Party committee and the municipal government, insisting on the wartime thinking and establishment of high-quality management team and effective goal management focusing on details and actual needs of medical staff.
ABSTRACT
Objective:The aim of this study was to evaluate different root canal obturation techniques on apical sealing ability of iRoot SP.Methods:Thirty-six single root mandibular premolar were collected. The root canals were mechanically instrumented with ProTaper rotary files to F3. The prepared samples were randomly divided into four experimental groups ( n=8) for root canal filling. The remaining four teeth were classified as a negative group ( n=2) and a positive control group ( n=2) respectively. The canals in the four experimental groups were obturated with gutta-percha and (or) iRoot SP, by either cold lateral compaction technique (CLC), continuous wave condensation technique (CWC), single-core technique (SC) or Sealer only backfill technique (SOB) respectively. The samples were then placed in a 37 ℃ water bath for 7 days to allow completely harden. All samples of experimental groups were sealed with nail polish except 1 mm from the apex and negative control group was fully enclosed while positive control group was fully open, then all root tips were immersed in 0.1% methylene blue solution for 7 days, then cut along the long axis of the tooth on a low-speed microtome, observed under a microscope (X10) and photographed. The software of image J was used to measure the apical leakage. Results:Apical microleakage were present in all filling techniques. SC technology showed higher apical leakage [(5.02±2.23)mm], while CWC showed lower [(3.59±1.76)mm], but there were no statistical difference ( P>0.05). Conclusions:All filling techniques can not completely seal the root apical, SOB technology has the similar apical sealing performance as other techniques.
ABSTRACT
OBJECTIVE To understand pathogen distribution and drug sensitive rate of urinary system infection in our hospital,in order to avoid the clinic to use antibiotics blindly,make the resistant strains decreasing in number,and improve efficacy.METHODS The distribution and drug sensitivity of the pathogens causing urinary infection among the patients with urinary system infection were rectrospectively analyzed.RESULTS Totally 549 strains were isolated,G-bacteria were 333 strains,accounted for 60.66%,from them E.coli was 293 strains,accounted for 87.99%;and G+bacteria were 216 strains,accounted for 39.34%,from them Enterococcus,and Staphylococcus were the main ones.Of E.coli strains,the ESBLs(+) were 36.86%.The MRCNS accounted for 81.91%.The result of drug sensitivity showed that the sensitive rate of E.coli to meropenem and imipenem was 100.0%.The sensitive rate of ESBLs(+) E.coli to cefepime,cefotaxime and aztreonam was all lower than 50%,but that of ESBLs(-) to the above drugs was much higher than ESBLs(+).The sensitive rate of Enterococcus to vancomycin and teicoplanin was 100%.The sensitive rate of CNS to Vancomycin was 100%.CONCLUSIONS In order to decrease the produceing bacteria resistance and the disseminating the resistance genes,it′s necessary to enhance the monitoring and study of bacteria resistance,normlalize the clinical medicine application,and enhance the infection control measures.
