Objective To understand the current status of the preferences and opinions on the investigator-initiated trails (IIT) of the neurosurgeons participating in INTERACT3 in China, as well as the design preference for IIT projects, and to provide a basis for the design and organization of multi-center clinical studies in the future. Methods Neurosurgeons with different seniority and professional titles from 89 domestic research institutions participating in the INTERACT3 project were collected from September to October 2023. The questionnaires were collected by questionnaire star. Results A total of 56 valid questionnaires were collected from 29 units. Among the 56 respondents, 52 neurosurgeons (92.86%) were from teaching hospitals and 45 (80.36%) were from grade A tertiary hospitals. 30 neurosurgeons (53.57%) had experience in conducting various clinical studies, and 55 neurosurgeons (98.21%) had experience in participating in various clinical studies. The main purposes of presiding over or participating in clinical research focused on “accumulating relevant experience and preparing for future projects” and “standardizing clinical diagnosis and treatment”, which were 89.29% and 83.93%. Respectively, regarding the way the case report form completing, respondents preferred to use electronic data collection systems (83.93%). Conclusions The purpose of the neurosurgeons interviewed to host or participate in clinical research is mainly to assist clinical and scientific research. Economic reasons have little impact on whether to participate in clinical research. The rationality and ease of operation of the trail design are the keys to attracting respondents to participate in clinical researches, and the level of remuneration has little impact on the decision-making of the respondents. The safety of clinical studies and the difficulty of enrolling subjects are the key factors that hinder respondents’ participation in clinical studies.

This article reviews the current application status of AI technology in DBS therapy and explores its future development prospects, providing new solutions for significant improvement in patients’ quality of life.
【摘要】 目的 分析手术治疗垂体瘤患者长期临床恢复以及生活质量改善情况。 方法 回顾性分析2007年12月-2008年9月手术治疗的103例垂体瘤患者术前以及术后长期随访资料，使用SF-36量表对术前、术后患者生活质量进行评估，分析手术治疗前后患者症状、激素水平恢复情况以及生活质量改善情况，并进一步分析肿瘤大小、侵袭程度对术后生活质量的影响。 结果 术后头痛症状消失52例，视力改善76例，其他症状具有不同程度改善；术后SF-36生活质量评估结果显示，患者除精神健康外的7个维度（生理机能、生理职能、躯体疼痛、一般健康状况、精力、社会功能、情感职能）均有明显改善（P＜0.05），不同肿瘤大小及侵袭程度的患者术后生活质量评分均无统计学意义（P＞0.05），垂体功能完全恢复者生活质量评分高于垂体功能低下者（P＜0.05）。 结论 显微手术治疗垂体瘤患者可明显改善患者的一般症状、提高患者的生活质量，单纯肿瘤的大小和侵袭程度对术后生活质量的影响程度较小，术后垂体功能的恢复程度明显影响患者的生活质量，垂体瘤术后患者的激素长期替代治疗尚需进一步加强。【Abstract】 Objective To analyze the long-term clinical recovery and quality of life (QoL) in patients with pituitary adenoma treated by microneurosurgery. Methods The clinical data of 103 patients undergoing microneurosurgery from December 2007 to September 2008 were retrospectively analyzed, health-related questionnairs (SF-36) were used to assess the QoL. The post-surgery recovery of symptoms, endocrine function, and QoL were compared with those of pre-surgery, then the correlation between tumor size, invasive behavior, and QoL were analyzed. Results Headache disappeared in 52 patients. Visual symptoms improved in 76 patients. Other symptoms were also improved. Seven concepts (physical functioning, role physical, bodily pain, general health, vitality, social functioning, role emotioning) were improved after surgery (Plt;0.05). The eight health concepts of SF-36 showed no significant difference between patients with different tumor size and invasive behavior (Pgt;0.05). Differences were considered statistically significant between normal and abnormal pituitary function groups after surgery(Plt;0.05) in all concepts. Conclusion Microneurosurgical treatment can improve the general symptoms and the QoL. The tumor size and invasion have little influence on the QoL after surgery, but the improvement of hormone deficiency has influence on the QoL significantly. More attention should be given to the long-term hormone replacement therapy after the pituitary adenoma surgery.
Neurosurgery navigation system, which is expensive and complicated to operate, has a low penetration rate, and is only found in some large medical institutions. In order to meet the needs of other small and medium-sized medical institutions for neurosurgical navigation systems, the scalp localization system of neurosurgery based on augmented reality (AR) theory was developed. AR technology is used to fuse virtual world images with real images. The system integrates computed tomography (CT) or magnetic resonance imaging (MRI) with the patient's head in real life to achieve the scalp positioning. This article focuses on the key points of Digital Imaging and Communications in Medicine (DICOM) standard, three-dimensional (3D) reconstruction, and AR image layer fusion in medical image visualization. This research shows that the system is suitable for a variety of mobile phones, can achieve two-dimensional (2D) image display, 3D rendering and clinical scalp positioning application, which has a certain significance for the auxiliary neurosurgical head surface positioning.
Objective To summarize the latest developments in neurosurgical treatments for neurofibromatosis type 1 (NF1) and explore therapeutic strategies to provide comprehensive treatment guidelines for clinicians. Methods The recent domestic and international literature and clinical cases in the field of NF1 were reviewed. The main types of neurological complications associated with NF1 and their treatments were thorough summarized and the future research directions in neurosurgery was analyzed. Results NF1 frequently results in complex and diverse lesions in the central and peripheral nervous systems, particularly low-grade gliomas in the brain and spinal canal and paraspinal neurofibromas. Treatment decisions should be made by a multidisciplinary team. Symptomatic plexiform neurofibromas and tumors with malignant imaging evidence require neurosurgical intervention. The goals of surgery include reducing tumor size, alleviating pain, and improving appearance. Postoperative functional rehabilitation exercises, long-term multidisciplinary follow-up, and psychosocial interventions are crucial for improving the quality of life for patients. Advanced imaging guidance systems and artificial intelligence technologies can help increase tumor resection rates and reduce recurrence. Conclusion Neurosurgical intervention is the primary treatment for symptomatic plexiform neurofibromas and malignant peripheral nerve sheath tumors when medical treatment is ineffective and the lesions progress rapidly. Preoperative multidisciplinary assessment, intraoperative electrophysiological monitoring, and advanced surgical assistance devices significantly enhance surgical efficacy and safety. Future research should continue to explore new surgical techniques and improve postoperative management strategies to achieve more precise and personalized treatment for NF1 patients.
