ObjectiveTo investigate the possible mechanism of Buzhong Yulin Decoction (补中愈淋汤) in the prevention and treatment of recurrent urinary tract infection. MethodsThe mouse models of recurrent urinary tract infection were established by uropathogenic Escherichia coli (UPEC) strain UTI89 by bladder perfusion, and the successful mouse models were randomly divided into a model group, an antibiotic group, and a low- and high-dose Buzhong Yulin Decoction group, with six mice in each group. In addition, 5 C57BL/6 mice without modelling were taken as blank group. The low- and high-dose Buzhong Yulin Decoction groups received 0.1 ml/10 g of decoction by gavage, with concentrations of 1.3 g/ml and 5.2 g/ml, respectively; the antibiotic group received 0.1 ml/10 g of levofloxacin hydrochloride solution with 5 mg/ml by gavage; the blank and model groups received 0.1 ml/10 g of distilled water by gavage. Each group was gavaged once a day for 7 consecutive days. The total number of urine marks, the number of central urine marks, and the total urine volume of the urine marks were observed by the urine marking test; HE staining was used to observe the histopathological changes in the bladder of mice; serum levels of the inflammatory factors interleukin 1β (IL-1β), interleukin 6 (IL-6) and tumour necrosis factor α (TNF-α) were detected by ELISA; the morphology of the epithelial cells of bladder was observed by scanning electron microscopy; immunofluorescence assay to detect bladder tissue anti-UroPlakin 3A protein level and UPEC bacterial load; the spread plate method to detect urinary bacterial load and bacterial load of bladder epithelial cells; RT-PCR method to detect Ras-related protein Rab-11A (RAB11A) and Ras-related protein Rab-27B (RAB27B) mRNA level in bladder tissue; immunoblotting to detect microtubule-associated protein 1 light chain3 (LC3) and P62 protein levels in bladder tissue. ResultsCompared with the blank group, the bladder epithelial cell layers were lost and showed abnormal morphology in mice of the model group; bladder tissue UroPlakin 3A protein and RAB11A and RAB27B mRNA levels reduced, the total number of urine marks, the number of central urine marks, bladder tissue UPEC bacterial load, urinary bacterial load, bacterial load in bladder epithelial cells, serum IL-1β, IL-6, and TNF-α levels, and LC3 and P62 protein levels in bladder tissue all elevated (P<0.05 or P<0.01). Compared with the model group, the bladder epithelial cell layers were intact and the morphology of epithelial cells were regular in the low- and high-dose Buzhong Yulin Decoction groups; the average surface area of bladder epithelial cells reduced, the levels of UroPlakin 3A protein and RAB11A and RAB27B mRNA in bladder tissues elevated, and total number of urine marks, the number of central urine marks, bladder tissue UPEC bacterial load, urinary bacterial load, bacterial load in bladder epithelial cells, serum IL-1β, IL-6, and TNF-α levels, and P62 protein levels in bladder tissue all reduced (P<0.05 or P<0.01), but LC3 protein levels showed no statistically significant (P>0.05). In the antibiotic group, the bladder epithelial cells were partially missing and the morphology of epithelial cells was abnormal. Compared with the antibiotic group, the average surface area of the bladder epithelial cells in the mice increased in the low- and high-dose Buzhong Yulin Decoction groups, the bacterial load of the bladder epithelial cells decreased, and the P62 protein level of the bladder tissue decreased (P<0.05). When comparing between the low- and high-dose Buzhong Yulin Decoction groups, the differences in each index were not statistically significant (P>0.05). ConclusionBuzhong Yulin Decoction may prevent and treat recurrent urinary tract infection by repairing the bladder mucosal barrier, increasing RAB11A and RAB27B level and enhancing autophagy in bladder tissues, thereby facilitating bacterial clearance from bladder epithelial cells and reducing the bacterial load of bladder epithelial cells.

Objective:To understand the clinical prevalence and drug resistance of Raoultella ornithinolytica, and to analyze the drug-resistant characteristics of carbapenem-resistant strains. Methods:A total of 83 clinical isolates of R.ornithinolytica, identified using matrix-assisted laser desorption ionization time-of-flight mass spectrometry between May 2015 and December 2020, were collected. Clinical information, drug-resistant phenotype, and carbapenemase gene of the carbapenem resistant strains were analyzed. Homology of the resistant strains was examined by pulse-field gel electrophoresis (PFGE). The molecular characteristics of plasmids, drug resistance genes and virulence genes were determined by whole genome sequencing (WGS), and a phylogenetic tree was constructed based on core single-nucleotide polymorphisms(core-SNPs) for evolutionary analysis of the carbapenem-resistant strains. Results:All 83 clinical isolates were confirmed as R.ornithinolytica, of which 11 strains were resistant to carbapenem antibiotics. The resistant strains were mainly sourced from the drainage fluid and wound secretions of patients in surgery, intensive care unit and oncology department. In addition to carbapenems resistances, the 11 strains were also resistant to cephalosporins, cephamycins, and aztreonam, while maintaining good in vitro activity to levofloxacin, tigecycline and colistin. Carbapenemase gene detection showed that 8 strains carried the bla IMP-4, 3 carried bla KPC-2, of which 1 strain carried both bla IMP-4 and bla KPC-2, and 2 strains carried both bla IMP-4 and bla NDM-1. PFGE results showed 7 banding types and 4 epidemic strains. WGS identified plasmid replicon types carried by the 11 strains of R. ornithinolyticus including IncFIA, IncFIB, IncHI1B, IncU, repB and Col, along with 10 additional types of drug resistance genes. Iron carrier related virulence genes entB, fyu, ybt and irp were detected in all carbapenem-resistant strains. Phylogenetic analysis showed that Ro6348 and Ro6050, Ro7401 and Ro7242, Ro8647 and Ro5832, and Ro9907 and Ro8856 were grouped together, while Ro8454, Ro7349 and Ro7326 were located on different branches. Conclusions:The overall drug resistance of R. ornithinolytica closely resembles Klebsiella pneumoniae and carries a variety of drug-resistant genes, but differs from domestic K.pneumoniae in that its carbapenemase is mainly IMP-4. PFGE and phylogenetic analysis results suggest that the strain has a tendency of mutual transmission in hospital, which deserves more attention.
