股骨转子间骨折微创内固定术的临床分析

目的回顾分析股骨转子间骨折微创内固定术以提高其临床疗效.方法回顾分析C形臂X线光机透视下闭合复位,经皮动力髋螺钉(DHS)内固定术治疗股骨转子间骨折109例,男68例,女41例;年龄42～92岁,平均67.5岁.结果切口长度平均5.1cm;出血量平均49.5ml;手术时间平均38分钟;骨折全部愈合,临床愈合时间58～82天,平均66.5天;2例改切开复位内固定术;2例切口形成血肿;2例术中股骨颈后壁磨穿;1例因过度内旋固定致髋关节外旋受限;其余108例髋关节功能均正常.3例套筒钢板与股骨纵轴不一致;2例股外侧肌医源性损伤.X线评价:5例粗隆上移0.8～1.5cm;109例中未见髋内翻、髋螺钉切割、拔出或穿透股骨头.结论经皮DHS内固定术,是目前治疗股骨转子间骨折新的理想的微创治疗技术.严格掌握手术适应症,正确的手术操作,适时进行康复锻炼是治疗成功的关键,但微创手术内固定器械尚有待改进.

An alternative mechanism of actions for neuroleptic and antidepressant drugs

It has earlier been proposed by the author that the aetiology of schizophrenic symptomatology may be due to the presence of abnormally connected interhemispheric fibres which link specialised functions in the brains of schizophrenics that are not connected in normal subjects, and that the neuroleptic drugs may produce their action through a local anaesthetic-like effect in suppression of conduction in these fibres. This line of thought has been extended here to consider the possible mechanism of action of the neuroleptic drugs in more detail, as well as that of the tricyclic antidepressant drugs which are derivatives of the phenothiazine group. Pharmacological similarities with the local anaesthetics both structurally and functionally have been considered, as well as the effects that these drug groups may have in common with the lithium salts. It has been suggested that these drugs all produce their primary effect on cell membranes, though not necessarily at the synapse, that the time course of their clinical effect may correlate with their incorporation into various cell membranes within the CNS, and that they may thus bring about a fundamental alteration in cell membrane microstructure. The possible role of electroconvulsive therapy has also been considered. The corollary of this argument is that the affective disorders may be genetically determined diseases of cell membrane microstructure.     

Hyperthyroidism associated with papilloedema and pyramidal tract involvement

Summary In a patient with mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes [MELAS] who had normal mitochondrial enzyme activity, high doses of coenzyme Q₁₀ (CoQ) were administered. Clinical improvement with decreased serum lactate and pyruvate levels was observed. Though the mechanism of action of CoQ is not known, a trial is worthwhile in patients with MELAS.     

BorrmannⅣ型胃癌的临床特征和外科治疗

目的探讨BorrmannⅣ型胃癌的临床特征和治疗方法。方法回顾性总结29例BorrmannⅣ型胃癌的临床资料,分析本型胃癌的临床表现、病理特点以及手术治疗的特殊性。结果全部患者均有上腹饱胀、隐痛不适、食欲不振,同时伴有明显的进行性消瘦,短期内体重明显减轻等临床症状。术前病理确诊为本型胃癌者24例。5例患者胃镜诊断为浅表型胃炎。获根治性切除22例,姑息性远侧胃切除者3例,放弃手术者4例。其1、2、3年生存率分别为38.9%、8.3%、0%。结论(1)BorrmannⅣ型胃癌是一种恶性程度极高的胃癌,其具有独特的生物学特性,治疗效果差,生存期短,预后不佳。(2)对BorrmannⅣ型胃癌应强调以根治性全胃切除和联合脏器切除为主的综合治疗方法。     

合并心律失常的心力衰竭56例治疗评价

目的探讨心力衰竭并发心律失常的发病规律及治疗方法。方法回顾性分析了93例慢性心力衰竭病人的临床资料，包括临床特点、诊断治疗方法以及预后。结果心律失常发生率为60．2％，以室性早搏发生率最高32．1％，其次是房性早搏26．8％，心房纤颤21．4％，其他19．7％，经治疗有效71例，总有效率76．3％。结论纠正心功能不全是治疗的关键，应根据具体情况选择性地应用抗心律失常药。     

超声造影在肝癌介入治疗后疗效评价中的应用

目的:探讨实时灰阶超声造影(contrast-enhanced grey-scale ultrasonography,CE-US)在肝癌介入治疗后疗效评价中的应用价值。方法:经肘前浅静脉团注超声对比剂SonoVue,观察各时相病灶的强化特点,并与治疗前CE-US、治疗后CT、MRI图像及随访结果进行比较,综合判断介入治疗效果。结果:CE-US可以清晰地显示病灶内有无局部或整体强化,能准确评价肝癌介入治疗后疗效。结论:CE-US在评价肝癌介入疗效时具有重要的临床价值。     

桡骨远端骨折三种治疗方法的疗效分析

目的探讨桡骨远端骨折的治疗效果。方法对桡骨远端骨折137例（150侧）的资料进行分析，采用AO分型法对骨折分类，治疗方法包括切开复位内固定，闭合复位半环架外固定，闭合复位石膏外固定。结果本组均获随访，平均随访时间12．7个月。所有患者按Dienst评分系统进行综合评分。A型骨折的总优良率82．85％，B型骨折的总优良率67．69％，C型骨折的总优良率48．00％。A型骨折中切开复位与手法复位的优良率无明显差别，B型骨折中切开复位植骨内固定的优良率最高，C型骨折的外固定组的优良率最高。结论损伤小的患者，疗效整体较好。A型骨折各种处理方法的优良率差别不大，B型骨折中切开复位植骨内固定的方法整体的优良率较高，C型骨折采用闭合复位半环架外固定的疗效相对较好。     

颈椎病合并下颈椎不稳的外科治疗策略

目的 探讨颈椎病合并下颈椎不稳的临床诊断、术式选择及手术疗效。方法 对手术治疗的32例颈椎病合并下颈椎不稳，分别摄术前及术后随访之颈椎正侧位、伸屈侧位X线片及颈椎MR检查。32例均经前路行减压、植骨融合、内固定手术治疗。以颈椎不稳节段与颈椎主要退变节段重合，并行减压内固定患者为A组，共7例；对25例颈椎不稳与颈椎病节段不重合，以其中仅处理颈椎病节段9例为B组；在处理颈椎病节段同时处理颈椎不稳节段16例为C组。以“40分”评分法分别对患者术前、术后随访情况予以评价，对数据分别行组间均值t检验及组内配对t检验。结果 经12～36个月随访（平均25个月），所有患者均获骨性融合，平均改善率61．2％。A、B、C组间均值t检验：术前差异无显著性（P〉0．05）、术后差异亦无显著性（P〉0．05）。各组内配对t检验，术前、术后随访差异均有显著性（P〈0．05）。结论 在颈椎病合并下颈椎不稳的患者中，不稳节段与主要退变节段关系密切但往往并不重合。通过颈前路手术，在处理颈椎病节段同时处理相邻颈椎不稳节段，临床疗效满意。
