Objective To develop a refined management model for operating rooms and assess its clinical impact on op-erational efficiency and cost control.Methods The study included 10,728 elective surgeries from January to June 2024 as the study group and 9 414 elective surgeries from January to June 2023 as the control group.The differences in operational metrics before and after implementing the refined management model were compared.The model was developed through comprehensive management by hospital leadership and multi-department collaboration,focusing on management structure,systems,processes,information technology,and resource allocation.Results In terms of efficiency,the on-time start rate of the first surgeries in the study group was significantly higher than in the control group(P＜0.05).The turnover time between surgeries was shorter in the study group(P＜0.01),and the rate of unexpected surgery cancellations was lower(P＜0.01).The average cost per surgery for consumables,excluding the impact of centralized procurement of consumables,was approximately 971 yuan,representing an 11% reduction compared to the previous year,despite a 14% increase in surgical volume.The average daily operating cost per operating room was about 12 303 yuan,a 7% reduction.Economic benefits increased by 8.43 million yuan,a 38% year-on-year increase.Conclusion Implementing a refined management model in operating rooms can significantly enhance efficiency,re-duce costs,and achieve dual improvements in social and economic benefits.

Objective To investigate the vaginal flora in patients with recurrent vulvovaginal candidiasis (RVVC).Methods Vaginal swabs were collected at different time points from 6 RVVC patients and 5 healthy women of child-bearing age.The dynamic changes,microbiota composition,alpha diversity and beta diversity in the two groups were assessed by analyzing the 16S rRNA V4 hypervariable region amplified from the total genomic DNA from the swabs.Results Lactobacillus was the predominant species in healthy women with similar proportions of Liners and L.crispatus;small proportions of Gardnerella,Prevotella and other genus were also detected.In some healthy women,the vaginal flora showed a high relative abundance of anaerobic bacteria such as Gardnerella,Prevotella,Atopobium,Sneathia.Compared with the healthy women,patients with RVVC showed a significantly reduced diversity of vaginal flora,where Liners was the predominant species and the content of L.crispatus decreased significantly.In healthy women,the vaginal flora fluctuated with the menstrual cycle,and the fluctuation was the most prominent during menstruation;the dominant species either alternated regularly or maintain an absolute superiority in the menstrual cycle.The vaginal flora showed attenuated fluctuation in women with RVVC,were highly conserved within the menstrual cycle,and maintained a similar composition in the episodes and intermittent periods.Conclusion The vaginal flora of RVVC patients do not undergo regular variations with the menstrual cycle and shows a similar composition between the episodes and intermittent periods.Promoting the production of L.iners or inhibiting the colonization of L.crispatus to restore the composition of the vaginal flora may help in the treatment of RVVC.

Objective To observe the therapeutic effect of NF-κB gene short hairpin RNA (shRNA) on endometriosis and identify the function of NF-κB on the maintenance and development of endometriosis in Macaca fascicularis.Methods The Macaca fascicularis model of endometriosis was developed,which divided into experimental group,negative control group and simple model group.The high specificity adenovirus vector mediated shRNA targeting NF-κB gene and negative control shRNA adenovirus with no-load NF-κB gene were synthesised.The experimental group injected the adenovirus which carried the NF-κB shRNA into the endometriosis lesions under laparoscopy surgery,the negative control group with no-load shRNA adenovirus and the simple models group injected with normal saline.Four weeks later after the injection,an observed operation was performed through laparoscopy and some lesions were collected.The CD34 immunohistochemistry of these lesions were done to detect the microvessel density,then the variation of the microvessel density among each group were observed.The expression of the NF-κB and proliferating cell nuclear antigen (PCNA) were detected through western blot.Results First,the Macaca fascicularis model of endometriosis was successful developed,and the experimental group has an evident atrophy in ectopic lesions compared with the previous.The lesions' microvessel density in experimental group decreased evidently compared with the negative control group and simple model group (0.002 0±0.000 3 versus 0.021 9±0.002 6 versus 0.024 5±0.003 3),and the differences was statistically significant (P＜0.01).The expression of PCNA (0.37±0.17 versus 0.57±0.26 versus 0.57±0.28) and NF-κB (0.338 ± 0.174 versus 0.678 ± 0.021 versus 0.645 ±0.098) in experiment group was lower than the negative control group and simple model group,the differences were statistically significant (all P＜0.01).Conclusion Through targeting suppressed the NF-κB gene expression by NF-κB shRNA,we can inhibit the development of endometriosis through reducing the ability of angiogenesis and cell proliferation of ectopic endometrial cells.

OBJECTIVETo assess the effect of a high specific adenovirus vector-mediated shRNA targeting nuclear factor-κB (NF-κB) on cell proliferation of the endometrium of Macaca fascicularis.

METHODSThe adenoviral vector NF-κB-p65-shRNA and the empty vector were separately trasnfected in cultured endometrial cells of Macaca fascicularis. The changes in the expression of the target gene protein and apoptotic proteins, cell proliferation, and cell cycle distribution were observed after the transfection.

RESULTSCompared with the control cells, infection of the endometrial cells with the NF-κB-p65-shRNA adenovirus significantly increased the expression levels of apoptotic proteins, promoted apoptosis of the endometrial cells, and reduced the cells in division?stage.

CONCLUSIONSNF-κB-p65 shRNA adenovirus can effectively promote apoptosis of endometrial cells and inhibit the proliferation of endometrial cells of Macaca fascicularis.
