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.     

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。     

激素抵抗性哮喘的研究进展

支气管哮喘的本质是气道慢性非特异性炎症,肾上腺糖皮质激素抗炎治疗已成为哮喘现代治疗的主要方法。但约5%-10%的患者对激素治疗不敏感而成为难治性哮喘,这种对激素治疗效果较差的哮喘被称为“激素抵抗性哮喘”（steroid-resistant asthma,SRA）。其发生机制不明,可能与糖皮质激素受体β、基因表达和热休克蛋白异常等有关,免疫和非免疫治疗可以改善哮喘症状。     

Pneumatosis cystoides intestinii

Zusammenfassung Die Pneumatosis cystoides intestinii (PCI), das Auftreten submuköser oder subseröser, gasgefüllter Zysten in der Wand des Gastrointestinaltrakts, tritt als seltene Erkrankung ohne eindeutige Geschlechtspräferenz vorwiegend in der 3. bis 5. Lebensdekade auf. Atiopathogenetisch werden unterschiedliche Faktoren diskutiert, am wahrscheinlichsten ist eine bakterielle Ursache (Clostridium perfringens) in Verbindung mit einer minimalen Unterbrechung der Mukosaintegrität. Eine pathognomonische Symptomatik gibt es nicht, das klinische Bild reicht von asymptomatischen Zufallsbefunden bis zur Hämatochezie. Die Diagnose wird durch den Nachweis der Gaseinschlüsse mittels Abdomenübersichtsaufnahme und Kolonkontrasteinlauf gestellt. Als Behandlungsmethoden für symptomatische Patienten stehen Sauerstofftherapie, Antibiotikagabe (Metronidazol) und in schweren Fällen die Resektion des betroffenen Darmabschnitts zur Verfügung.

Pneumatosis cystoides intestinalis (PCI), a condition involving submucosal or subserosal gas-containing cysts of the wall of the gastrointestinal tract, is a rare entity. It is mostly diagnosed between the third and fifth decades of life without a clear sexual predominance. Different aetiopathogenetic factors are under discussion, the most probable being a bacteriologic cause (Clostridium perfringens) in combination with minimal leaks in mucosal barrier. There are no pathognomonic symptoms; the clinical picture ranges from incidental findings to haematochezia. Diagnosis is based on plain abdominal film and X-ray following barium enema. Methods of treatment in symptomatic cases are oxygen and antibiotic (metronidazole) therapies and, in severe cases, resection of the diseased part of the intestine.

     

气功对冠心病人CM_5ST段/心率斜率的影响

37名冠心病患者随机分为气功治疗组(22人)和对照组(15人)。气功治疗组接受12周动功治疗,对照组接受安慰剂治疗,治疗前后均测定CM_5 ST段/心率斜率。结果发现动功治疗组CM_5 ST段/心率斜率减少,而对照组不变或增大,两组有显著性差异,ST段下移及常规分级运动试验其它指标在两组间无显著差异。表明CM_5ST段/心率斜率是一个敏感的心肌缺血指标。
