3D-Slicer+Sina增强现实技术在脑室外引流术中的应用
2024年
目的探讨3D-Slicer+Sina增强现实技术对脑室外引流术中穿刺精准度和安全性的影响。方法采用回顾性病例对照研究。纳入广东医科大学附属医院神经外科2022年1月至2023年12月收治的行脑室外引流手术患者74例,按手术方式的不同分为观察组30例和对照组44例。观察组在3D-Slicer+Sina定位下行脑室外引流手术,对照组在传统CT定位下行脑室外引流手术。比较两组穿刺靶点偏移距离、穿刺次数、首次穿刺成功率、手术时长、术后并发症发生率、住院天数和住院费用等情况。结果观察组和对照组的穿刺例数分别为30例和44例,穿刺部位数分别为53个和72个,穿刺靶点偏移距离分别为(9.82±4.76)mm vs.(16.30±8.81)mm(P<0.001),穿刺次数为1(1,1)vs.1(1,1.75)(P=0.026),首次穿刺成功率为90.6%(48/53)vs.73.6%(53/72)(P=0.017),手术时长分别为85.00(64.75,107.50)min vs.70.00(55.00,90.00)min(P=0.040),术后并发症发生率为16.7%(5/30)vs.38.6%(17/44)(P=0.042),观察组均有明显优势。但两组住院天数和住院费用比较无统计学差异(P>0.05)。结论3D-Slicer+Sina辅助脑室外引流术可以提高脑室穿刺精准度和首次穿刺成功率,降低穿刺次数和术后并发症发生率,值得在临床上推广应用。

Comparison of da Vinci 5 with previous versions of da Vinci and Sina:A review
2024年
Robotic systems have become popular in modern surgical procedures.The option of telesurgery has effectively addressed geographic limitations.These systems are offered by numerous companies worldwide.In this review article,we discuss four models of robotic systems to determine their advantages:the Sina flex system from Iran and the da Vinci Xi,SP,and 5 systems from the USA.We compared aspects such as architecture,instruments,visualizations,clinical use,and costs.Our findings suggest that the da Vinci robot,which was introduced earlier than the Sina system,utilizes proprietary and limited-use EndoWrist instruments with diameters ranging from 8 to 12 mm and features advanced imaging capabilities,including three-dimensional optical,tomographic,and fluorescence imaging.It is well established and widely utilized in various surgical procedures.Conversely,the Sina flex system employs single-use 5 mm instruments and is equipped with two-dimensional optical imaging as a standard,with optional three-dimensional and fluorescence imaging upgrades available.Despite its affordability,the Sina flex system is relatively new and has not yet been clinically tested.Additionally,the Sina flex system is more user-friendly.

Profile of Renal Lithiasis in the Nephrology Department of the Ibn Sina University Hospital Center in Rabat
2024年
Introduction: Renal lithiasis is a very common condition worldwide, linked to the presence of calculi in the urinary tract. It is multifactorial, recurrent and serious. It is the 3rd leading cause of chronic kidney disease (CKD) in Morocco. The aim of our study is to describe the clinical, paraclinical and management aspects of renal lithiasis in our patients, to determine the factors of recurrence of renal lithiasis and to identify the factors of progression of renal failure. Materials and Methods: This is a retrospective, descriptive and analytical study conducted in the nephrology department of CHU IBN Sina in Rabat, over a 3-year period from 2020 to 2023. We included 160 patients with renal lithiasis having a follow-up in our training. We analyzed their epidemiological, clinical, paraclinical and therapeutic profile. Results: The mean age of our patients was 56 +/− 16.6 years, with a M/F sex ratio of 1.02. Lithiasis was expressed by renal colic in 71% of cases, and by stone emission in 31% of cases, although discovery was incidental in 16% of cases. At the time of the first consultation, 59% of patients had renal failure (RF), 15% of whom were at the stage of chronic end-stage renal disease. Crystalluria and calculus spectrophotometry were performed in only 30% and 22% of patients respectively. All patients benefited from hygienic and dietary measures according to the nature of the stone, as well as additional urological management. Recurrence of renal lithiasis was reported in 36% of cases. In univariate analysis, advanced age, male gender, diabetes, hypertension and the presence of recurrent urinary tract infection were factors in the progression to CKD (OR = 0.979, p = 0.035;OR = 0.527, p = 0.48;OR = 4.127, p = 0.015;OR = 1.926;p = 0.015, OR = 2.5 p = 0.019, respectively). In multivariate analysis, only diabetes and high baseline creatinine were factors in the progression to CKD. Recurrence of renal lithiasis was reported in 36.5% of cases. Only the presence of a history of familial lithiasis and of rena

Four-function model analysis of nonsuicidal self-injury-related posts on Sina Weibo
2024年
To the editor:Non-suicidal self-injury(NSSI)is defined as direct,repetitive self-injury to bodily tissues without suicidal intent. The estimated prevalence of NsSI among adolescents is 17.2%worldwide with a comparable rate observed in China. As a behavioural addiction, NSSI poses a significant suicide risk,and is emerging as a major mental health problem among adolescents.To unravel this puzzle,the four-function model(FFM)distinguishes between interpersonal and intrapersonal functions,as well as positive and negative reinforcement functions,proving relatively comprehensive among various theoretical models.

社交媒体主题的周期性对其主题触发能力的影响——基于新浪微博的样本分析
2024年
[研究目的]分析社交媒体中主题周期特征对主题之间的触发关系影响,为社交媒体舆论引导、信息调控提供有效的调控手段与推进。[研究方法]采取小波分析及其红噪声检验、格兰杰因果分析的主要方法,以新浪微博三年共32779920条帖子为样本,分析和检验微博中主题的不同周期性特征是否对其主题触发和影响舆论的能力有不同作用。[研究结论]主题的特定周期具有对主题触发能力的影响:7天、49天等7天或7的多倍的周期对该主题的触发能力有正面影响;主题的周期数量具有对其触发能力的影响:周期数量和议程的触发能力、被触发能力均有正相关性;主题的周期长度特征具有对其触发能力的影响:最短周期越短则该主题的触发能力越强;最长周期越长则该主题的触发能力也越强。该研究可为社交网络的舆情调控、议程演化的管理引导提供参考。主题具有的周期特征使其产生主题触发的原因、机理和功能,是有待拓展的研究领域。
