The operating room was the core department of a hospital,and its operational efficiency had a significant impact on the high-quality development of a hospital.An analysis has revealed that low efficiency and irrational allocation in the operating room were mainly due to the lack of operational regulations and norms,the unreasonable arrangement of surgical specialties,and the unbalanced allocation of supporting resources.To address these issues,the First Affiliated Hospital of Zhengzhou University has taken into account the overall allocation of resources for the central operating room and the central operating room,and formulated strategies to improve operational efficiency,including adjusting the operational mechanism,optimizing the structure of surgical specialties,and providing corresponding supporting resources.Based on the adjustment of surgical structure,the implementation effect of the program was measured and evaluated,which provided practical strategies for optimizing operating room efficiency in hospitals.

The increasing operating pressure of large public hospitals has forced hospitals to focus on opening up income sources and reducing expenditure.The purchase and maintenance of medical equipment is one of the important economic activities of hospi-tals.However,there are problems in large public hospitals,such as the argumentation for equipment acquisition ignoring evaluation of operational efficiency,the costing model that leads to a lack of willingness of departments to purchase equipment,and the lack of standard processes and systems for renting medical equipment among departments.Based on this,it explores the establishment of a medical equipment sharing operation mechanism in large public hospitals,promotes the improvement of the efficiency of medical equipment use in large public hospitals by establishing a medical equipment sharing center,standardizing the purchase of shared equipment,entering shared equipment information,setting up shared equipment leasing specifications,and clarifying the equipment return process and maintenance,so as to effectively control hospital operating costs,and help the high-quality development of public hospitals.

Objective: To investigate the molecular transmission network characteristics of HIV-1 among men who have sex with men (MSM) in Shaoxing City, Zhejiang Province, so as to provide insights into AIDS prevention and control among MSM. Methods: Newly reported HIV/AIDS cases among MSM in Shaoxing City were selected from January 2021 to September 2023. Plasma samples before the antiviral treatment were collected. The HIV-1 pol gene was amplified using reverse transcription PCR and nested PCR to construct phylogenetic trees for gene subtype analysis. The HIV-TRACE method was used to construct a molecular transmission network with a genetic distance of 1.5% to analyze clustering and the characteristics of cases within molecular clusters. Results: A total of 216 HIV/AIDS cases among MSM were included, and 179 qualified sequences were obtained. The predominant HIV-1 subtypes were CRF07_BC and CRF01_AE, with 95 and 66 cases, respectively. At 1.5% genetic distance, 20 molecular clusters were formed, with 61 nodes and 58 edges. A total of 61 sequences were connected to the transmission network (34.08%). HIV/AIDS cases among MSM from all the counties (cities, districts) in Shaoxing City were included in the network. There was the largest molecular cluster with ≥10 nodes, involving 12 cases from five counties (cities, districts), 3 medium-sized molecular clusters with 4 to 5 nodes, and the 16 small-sized molecular clusters with 2 or 3 nodes. Seven cases with high risk of transmission, each with ≥4 edges, were all CRF07_BC subtypes. Among them, two cases were from the large molecular cluster, and five cases were from the same molecular cluster composed of cases from Shengzhou City and Xinchang County. Conclusions The predominant HIV-1 subtypes among MSM in Shaoxing City were CRF07_BC and CRF01_AE. There was cross-regional HIV transmission, and potential transmission risk might exist in Shengzhou City and Xinchang County.

Objective To investigate the efficacy of antibacterial photodynamic therapy(aPDT)as an adjunct to subgingival scaling and root planning in the treatment of chronic periodontitis.Methods This study followed medical ethics guidelines,and informed consent was obtained from all patients.Sixteen patients were recruited for this random-ized split-mouth controlled trial.The control group underwent subgingival scaling and root planning(SRP),while the ex-perimental group received subgingival scaling and root planing plus aPDT treatment using Perowave? with a toluidine blue O solution photosensitizer.The probing pocket depth(PD),recession,plaque index(PLI),bleeding index(BI)and proportion of positive sites of bleeding on probing(BOP)(BOP%)at all sites were examined at baseline(before treat-ment)and at 1,3 and 6 months after treatment.Results Follow-up was completed for 13 patients.On the control side,356 teeth were tested at 2 136 sites.A total of 360 teeth on the test side and 2 160 sites were included in the study.Before treatment,there was no significant difference in the baseline indicators between the two groups.After treatment,both groups showed significant improvement in clinical parameters,including PD,PLI,BI,and BOP%,compared with baseline.At 3 months,the BOP%and PLI in the experimental group were significantly lower than those in the control group(P＜0.05).The improvement in BOP%and PLI in the experimental group was significantly greater than that in the control group 3 months after treatment(P＜0.05).Conclusion aPDT,as an adjuvant treatment to SRP for chronic periodontitis,can improve gingival bleeding and control periodontal inflammation in the early stage.
