Medical equipment management plays a crucial role in enhancing the quality and efficiency of healthcare services. However, traditional management approaches are increasingly inadequate to meet the growing demands of modern healthcare. As intelligent operation and maintenance (O&M) models based on big data, the Internet of Things (IoT), and artificial intelligence (AI) technologies develop, it is imperative to explore their application in medical equipment management. This paper reviews the technical overview of intelligent O&M and discusses the algorithms and challenges of intelligent O&M models based on different technologies. It also proposes issues that need improvement in intelligent O&M models, aiming to provide valuable references for the future development of medical equipment management.

Objective To evaluate the effectiveness and safety of indocyanine green fluorescence method versus modified inflation-deflation method for thoracoscopic anatomic segmentectomy. Methods CNKI, Wanfang Database, China Biomedical Literature Database, Web of Science, Cochrane Library, EMbase, PubMed, Clinicaltrials.gov, were searched from 1 January 2000 to 1 May 2023, and controlled studies between indocyanine green fluorescence and modified inflation deflation method in thoracoscopic segmentectomy were collected. Meta-analysis was performed using Stata14MP and RevMan5.4. Results A total of 10 articles, including 1 156 patients, were identified. In thoracoscopic anatomic segmentectomy, indocyanine green fluorescence method had an advantage over modified inflation deflation method. The total incidence of postoperative complications decreased (OR=0.51, 95%CI 0.36 to 0.71, P<0.0001). The incidence of air leaks decreased (OR=0.50, 95%CI 0.31 to 0.80, P=0.004), the operation time shortened (MD=−25.81, 95%CI −29.78 to −21.84, P<0.00001), the length of postoperative hospital stays shortened (MD=−0.98, 95%CI −1.57 to −0.39, P=0.001), the rate of clear displaying for intersegmental boundary line increased (OR=5.79, 95%CI 2.76 to 12.15, P<0.00001). The difference was statistically significant. Conclusion Compared with modified inflation deflation method, indocyanine green fluorescence method can quickly and clearly display the intersegmental boundary line, reduce the difficulty of surgery, shorten the operation time, reduce the length of postoperative hospital stay, and provide reliably technical support for thoracoscopic anatomic segmentectomy. It is an effective and safe method, which is worthy of extensive application.

By studying the current situation of multi-agent collaborative innovation and clinical achievements transformation at home and abroad, it is clear that multi-agent collaborative innovation is the only way for clinical research achievements transformation under the current background. This paper proposes a set of transformation path of clinical research achievements based on the multi-agent collaborative innovation platform of "production, teaching, research and medicine", which is supported by policy guidance and innovation management, and explore the role of equipment management department in achievement transformation.

Objective　To investigate the correlation between red cell distribution width to platelet ratio and short-term prognosis in acute ischemic stroke.Methods　The patients with ischemic stroke admitted in the First Affiliated Hospital of Zhengzhou University during the initial 24 hours after the onset of disease between 2015-2017 were recruited prospectively.Red cell distribution width (RDW),platelet and clinical characteristics were recorded.Functional outcome at 90 days after ischemic stroke was evaluated by the modified Rankin Scale (mRS).Results　Totally 1106 patients were included.Patients with poor functional outcome were older (P＜0.001=and had more frequent histories of hypertension (P=0.015),diabetes (P=0.001),atrial fibrillation (P＜0.001=,coronary heart disease (P=0.041),stroke (P＜0.001=and higher National Institutes of Health Stroke Scale (NIHSS)(P＜0.001=,white blood cell count (P＜0.001=,RDW (P＜0.001=and RDW to platelet ratio (RPR) (P=0.034).Higher RPR levels were associated with poor functional outcome at 90 days after ischemic stroke［(odds ratio,OR) 1.09,(confidence interval,CI) 1.03~1.16，P=0.005］. Conclusion　Higher RPR levels were associated with poor short-term outcome after acute ischemic stroke.

In terms of service management in the medical equipment field, Medical Equipment after-sale Service Satisfaction Evaluation System is established through expert consultation and sample experiment. Meanwhile, questionnaire survey has been applied to local service satisfaction survey work among equipment managements and clinical departments in seventy second and third grade hospitals in Shanghai in ten consecutive years. The result indicates that the satisfaction index has been growing slightly and stably, which clearly demonstrates that the evaluation has continually boosted the service work of various mainstream suppliers. And overall, the evaluation has played an active role in safeguarding and motivating the safety and effectiveness of medical equipment.

Taking Endoscopy in hospitals as the research object, study on the safety risk characteristics in digital integration environment. On the basis of risk analysis, risk prevention and control measures are proposed from personnel, equipment, water and electricity, disinfection and the surrounding environment. Establish the endoscope safety risk management safeguard system to improve the safety risk management level of endoscopy.

Objective To study the radioprotective effect of polypeptide from Chlamys farreri (PCF) on ultraviolet B(UVB)-irradiated murine thmocytes in vitro. Methods The murine thymocytes were exposed to UVB radiation. MTT method was used to detect the cell viability. The activities of intracellular glutathione peroxidase (GSH-Px), superoxided dismutase(SOD) and catalase (CAT) were measured. Intracellular reactive oxygen species (ROS) and the effect of PCF on UVB-induced apoptosis were investigated by flow cytometry. Results PCF could greatly enhance the viability of murine thymocyte and markedly promote the activities of GSH-Px, SOD and CAT, while the amount of ROS was decreased. PCF could inhibit UVB-induced thymocyte apoptosis. Conclusion PCF has significant radioprotective effects on UVB-irradiated murine thymocytes in vitro.
