  • A comparative study of viscoelasticity between normal cornea and keratoconus

    Study of the mechanical properties of in vivo corneal materials is an important basis for further study of corneal physiological and pathological phenomena by means of finite element method. In this paper, the elastic coefficient (E) and viscous coefficient (η) of normal cornea and keratoconus under pulse pressure are calculated by using standard linear solid model with the data provided by corneal visualization scheimpflug technology. The results showed that there was a significant difference of E and η between normal cornea and keratoconus cornea (P < 0.05). Receiver operating characteristic curve analysis showed that the area under curve (AUC) for E, η and their combined indicators were 0.776, 0.895 and 0.948, respectively, which indicated that keratoconus could be predicted by E and η. The results of this study may provide a reference for the early diagnosis of keratoconus and avoid the occurrence of keratoconus after operation, so it has a certain clinical value.

  • Research progress on application of 3D visualization technology in laparoscopic precise hepatectomy

    ObjectiveTo investigate the role of 3D visualization technology in the laparoscopic precise hepatectomy. MethodsTo retrieve the literatures about the application of 3D visualization technology in laparoscopic precise hepatectomy, and summarize and analyzed them. ResultsThe application of 3D visualization in laparoscopic precise hepatectomy could effectively reduce the operative time, blood loss, blood transfusion rate, and total complication rate. The application of 3D visualization in preoperative evaluation of the resection surface and residual liver volume had been relatively mature. Although many organizations try to use 3D visualization in laparoscopic hepatectomy, such as laser registration and real-time intraoperative navigation, it had not been widely used in clinic because of technical limitations. ConclusionsExisting research results show that, the application of 3D visualization technology in laparoscopic precise hepatectomy can improve the resectability of lesions, increase perioperative safety, but intraoperative navigation is still need to be further developed before it is expected to be widely used in clinical practice. Existing evidence of increased benefit from laparoscopic precise hepatectomy with 3D reconstruction remains limited, and more rigorous randomized controlled trials of large cases are needed to confirm this.

  • CiteSpace-based visualization and analysis of the current state of medical prescription research

    Objective To analyze the research hotspots and development trend of medical advice at home and abroad, and provide the basis for the research related to medical advice in China. Methods The China National Knowledge Infrastructure and Web of Science were searched from January 1991 to November 2023 to collect domestic and international studies on medical prescriptions. Bibliometrics and CiteSpace software were used for analysis. Results A total of 3 155 articles were included. The number of publications on medical advice reached its peak in 2013, and the trend of domestic and foreign publications was consistent; the institution with the largest number of publications in China was Tongji Hospital of Tongji Medical College of Huazhong University of Science and Technology; the top three hotspots of attention in China were rational medication use, intravenous medication dispensing center and nursing care; the top three hotspots of attention in foreign countries were care, impact, and system; the top three hotspots of attention in China were intravenous medication (centralized) dispensing center and medical prescription audit 2 emergent words emergent rate had been continued to date; foreign polst, palliative care and advance care planning 3 emergent words emergent rate had been continued to date; domestic in the past five years, the key words were quality improvement, lean management, transitional care, rationality evaluation, prescription front audit system and medication adherence; the keywords for the last five years in foreign countries were assessmen, risk factor, clincial pathway. ConclusionsDomestic research on medical prescriptions needs to pay more attention to the decision-making of doctors when they give medical prescriptions and the timely monitoring of medication errors, and based on the more mature research on medical prescriptions in foreign countries, domestic research needs to combine the concepts of computer-assisted decision-making and value-based medicine to explore in-depth the correlation between medical prescriptions and the quality of medical care and patient value. It is also needed to combine computer-assisted decision-making and the concept of value-based medicine to explore the intrinsic connection between medical advice and medical quality and patient value.

  • Interpretation and visualization of the results of systematic review and meta-analysis—the perspectives of decision makers and patients

    Systematic review (SR) and meta-analysis, as the highest level of evidence-based medicine, are an indispensable part of guiding medical staff to make medical decisions. At the same time, the status of patients as shared decision-making is rising. At present, the results of SR and meta-analysis are mainly presented in the form of effect (relative risk or mean difference) and forest plot. The expression is not intuitive or professional. The process of evidence-based evidence guiding clinical decision-making lags behind, which cannot meet the needs of rapid decision-making. With the continuous progress in artificial intelligence and big data analysis tools, researchers have attempted to introduce visual presentations to improve the timeliness of clinical decision-making. Through the interpretation of the outcomes of SR and meta-analysis, this paper presents different visualization results from the perspective of patients and clinical decision-makers, which not only helps the majority of people without medical background understand clinical evidence more intuitively and participate in the process of clinical decision-making, but also helps improve residents' health literacy, promotes the dissemination and sharing of knowledge, and provides references for further promoting the technology of automatic decision-making system.

  • Three-dimensional Structural Visualization of Subthalamic Nucleus for Deep Brain Stimulation

    The effect of deep brain stimulation (DBS) surgery treatment for Parkinson's disease is determined by the accuracy of the electrodes placement and localization. The subthalamic nuclei (STN) as the implant target is small and has no clear boundary on the images. In addition, the intra-operative magnetic resonance images (MRI) have such a low resolution that the artifacts of the electrodes impact the observation. The three-dimensional (3D) visualization of STN and other nuclei nearby is able to provide the surgeons with direct and accurate localizing information. In this study, pre- and intra-operative MRIs of the Parkinson's disease patients were used to realize the 3D visualization. After making a co-registration between the high-resolution pre-operative MRIs and the low-resolution intra-operative MRIs, we normalized the MRIs into a standard atlas space. We used a special threshold mask to search the lead trajectories in each axial slice. After checking the location of the electrode contacts with the coronal MRIs of the patients, we reconstructed the whole lead trajectories. Then the STN and other nuclei nearby in the standard atlas space were visualized with the grey images of the standard atlas, accomplishing the lead reconstruction and nerve nuclei visualization near STN of all patients. This study provides intuitive and quantitative information to identify the accuracy of the DBS electrode implantation, which could help decide the post-operative programming setting.
