Since 1986 an epidemiologicalstudy onthe relation of silica dust exposure ,silico-sis and lung cancer was jointly made by TongjiMedical College , US National Cancer Institute andthe US …     

Transnasal Endoscopic and Transoral Approaches in the Biopsies of Ventral Atlas and Axis Vertebrae: A Comprehensive Retrospective Study for Preprocedural Scheme,Biopsy Procedure,Core Technique Analysis,Diagnostic Yield and Clinical Outcome

ObjectiveThis study aims to describe and analyze the transoral and transnasal approaches for pathologies of the ventral atlas and axis vertebrae, which are considered technically challenging regions for diagnostic biopsy.MethodsA series of transnasal endoscopic approach (TNA) and transoral approach (TOA) biopsies for the pathologies of the first and second cervical vertebrae were conducted and retrospectively analyzed from July 2014 to May 2021. The depth of the biopsy trajectory was measured on computed tomography images for all nine patients (eight males and one female with an average age of 58.11 ± 11.60 years), as were the coronal, sagittal, and vertical biopsy safe ranges. The characteristics of each lesion, including radiographic features, blood supply, and destruction of anterior or posterior vertebral body edges, were evaluated to guide the biopsy. Four biopsy core techniques (BCTs), including “lesion perforating”, “aspiration”, “cutting‐and‐scraping” and “biopsy forceps utilization” were elaborated in this study. The biopsy procedures and periprocedural precautions were demonstrated. Patient demographics, clinical data, lesion characteristics, diagnostic yield, and complications were recorded for each case.ResultsEight TOA biopsies for the axis vertebral body and one TNA biopsy for the atlas anterior arch were successfully performed and yielded adequate pathologies. All biopsies were organized based on the preprocedural radiographic measurements, which showed that the average length of biopsy trajectory and coronal, sagittal, and vertical safe biopsy ranges were 85.00 ± 5.88, 20.63 ± 4.75, 16.25 ± 1.49, and 24.63 ± 2.26 mm, respectively, and these corresponding data were 95, 36, 9, and 26 mm in the TNA patient. Six osteolytic lesions (66.7%), one osteoblastic lesion (11.1%), and two mixed lesions (22.2%) were observed, among which seven lesions had a rich blood supply. Biopsy forceps and core needles were utilized to obtain samples in six and three patients, respectively. All the TNA and TOA biopsies were performed with cooperative application of multiple BCTs under compound anatomic and stereotactic navigations. Intraprocedural or postprocedural complications occurred in no patients who underwent the biopsy in the follow‐up period (1–39 months). No significant differences were found between the preprocedural and postprocedural blood indexes and visual analogue scale scores.ConclusionWith a sophisticated preprocedural arrangement, cooperative application of BCTs, and careful periprocedural precautions, transnasal endoscopic and transoral biopsies are two feasible, efficient, and well‐tolerated procedures that achieve satisfactory diagnostic yield, complication rate, and clinical outcome.     

脑动脉硬化症中医临床分型研究

分裂样精神病与精神分裂症临床特征对照分析

目的探讨分裂样精神病与精神分裂症的临床特征,为分裂样精神病分类与诊断提供依据。方法将112例首次发病诊断为分裂样精神病患者,按病程达1mo痊愈否分为分裂样精神病组(痊愈者)43例,精神分裂症组(未愈者)69例,于入院初1w内开始收集入组患者的阳性家族史,Schneider一级症状的频度等临床资料,采用简明精神病量表评定精神症状,根据DSM-Ⅳ分别标明是否伴有预后良好的4项特征。结果分裂样精神病组简明精神病量表评分关心健康、焦虑、敌对、猜疑及定向障碍因子分显著高于精神分裂症组(P<0.01),而动作迟缓、情感平淡、不合作因子分显著低于精神分裂症组(P<0.05或0.01);4项预后良好特征及患者合作率均显著高于精神分裂症组(P<0.01);初诊前症状持续的平均时间及同一患者Schneider一级症状≥2条的频率均显著低于精神分裂症组(P<0.01)。结论分裂样精神病仅用病程标准区别于精神分裂症而不附加上述的内涵特征,则可能会包含异源性患者。     

疑诊中枢神经系统感染103例临床分析

目的探讨中枢神经系统(CNS)感染的诊断及鉴别诊断思路。方法回顾性分析以发热、头痛、神经系统功能缺损为首发症状,初诊疑诊CNS感染的住院患者103例,分析误诊原因。结果(1)确诊CNS感染92例,非CNS感染误诊CNS感染为8例,诊断不明3例。(2)CNS感染各病种之间的误诊以病毒性脑炎、结核性脑膜炎、脑肿瘤多见。结论对CNS感染临床诊治思路应遵循多发病多考虑,少发病少考虑的原则;尽早选择CSF检查,有助于早期诊断。     

创伤性颅脑损伤频响特性研究综述

频率在创伤性颅脑损伤(traumatic brain injury, TBI)的生物力学响应中扮演着重要角色,冲击载荷可因共振行为而放大脑部局部变形,加剧神经功能障碍。 本文总结了颅脑损伤频响特性的主要研究方法和发展进程,重点探讨不同数学方法在颅脑损伤频响特性中的应用,以及颅脑损伤频响特性的研究现状,并进一步提出深化颅脑损伤频响特性研究的建议。 结果表明,有限元法、降阶模型法和流固耦合法在颅脑损伤频响特性研究中均具可行性,但现有研究对颅脑固有频率尚未达成有效共识,且未将颅脑损伤的频响特性与评价准则进行结合,故基于频响特性完善颅脑损伤力学评价仍是研究的重点。
