钻孔闭式引流和YL-1型穿刺针引流治疗慢性硬膜下血肿的疗效观察

目的比较钻孔闭式引流和YL—1型穿刺针引流在治疗慢性硬膜下血肿(CSDH)的疗效。方法回顾分析了我院收治的62例CSDH病人,45例行钻孔闭式引流术(甲组),17例行YL—1型穿刺针引流术(乙组),比较两组治疗效果。结果甲组复发率为6.5％,并发症率为4.1％,乙组复发率为27.7％,并发症率为22.2％。结论钻孔闭式引流较YL-1型穿刺针引流可明显减少CSDH复发率和并发症发生率。     

Electrophysiological findings in immune checkpoint inhibitor-related peripheral neuropathy

ObjectiveTo report the electrodiagnostic features of immune checkpoint inhibitor (ICI)-related neuropathy.MethodsWe retrospectively reviewed clinical presentations and electrodiagnostic features of 23 patients studied after receiving immune checkpoint inhibitors (ICIs). The presentations for electrodiagnostic evaluation included an acute neuropathy or neuromuscular junction disorder. We applied established electrodiagnostic criteria for polyneuropathy and acute demyelinating neuropathy.ResultsWe identified acute demyelinating neuropathy (13 cases), axonal sensory motor neuropathy (5), pure sensory neuropathy (4) and mononeuropathy (1). 13 patients had acute demyelinating neuropathy confirmed by demonstrating demyelination in 2 or more nerves; 3 additional patients had demyelination in only one nerve. Analysis of motor nerve conduction parameters revealed demyelination involving median and ulnar nerve distal motor latencies as well as median, ulnar and peroneal nerve conduction velocities. Conduction block was found in median, ulnar and peroneal nerves. The remaining one-third patients without demyelination had acute painful axonal neuropathy. Coexisting myopathic changes (6) and neuromuscular junction dysfunction (4) were also identified.ConclusionsOur findings suggest that, while immune-mediated motor nerve demyelination is the primary underlying mechanism of ICI-related neuropathy, axonal painful neuropathy can also be an important presentation. Early recognition and effective intervention may reduce morbidity and permanent disability.SignificanceElectrophysiological studies might be useful in the evaluation of ICI-related neuropathy.     

Serum Levels of Maprotiline and Its Adverse Effects on Depressed Patients

Abstract: The relationships between the side effects of maprotiline (MPT) andthe serum concentration of MPT and desmethylmaprotiline (DMPT) were investigated with 27 blood samplings in 15 depressed inpatients. There were significant correlations between the side effects and serum levels of MPT and DMPT. Mild side effects frequently occurred at levels of more than 130 ng/ml of MPT and 70 ng/ml of DMPT. At more than 220 ng/ml of the MPT levels and 110 ng/ml of DMPT levels, severe side effects occurred. Nearly sigmoidalserum level/side effect response curves occurred with both compounds.     

阿立哌唑作为增效剂治疗强迫症的随机对照研究

目的探讨小剂量阿立哌唑作为增效剂治疗强迫症的疗效及安全性。方法 64例强迫症患者在帕罗西汀治疗的基础上,双盲、随机分为合用组[帕罗西汀合并阿立哌唑,阿立哌唑平均剂量（标准差）为7.9（1.3）mg/d]及对照组（帕罗西汀合并维生素C）,治疗8周。于治疗前及治疗后分别采用Yale-Brow强迫量表、治疗时出现的症状量表（TESS）评定药物疗效及不良反应。结果治疗前合用组和对照组帕罗西汀的平均剂量（标准差）分别为30.2（5.1）mg/d、29.6（6.1）mg/d,差异无统计学意义（t=0.86,P=0.291）;合用组和对照组Y-BOCS评分的均分（标准差）分别为25.0（2.4）、25.1（2.6）,差异无统计学意义（t=0.89,P=0.379）,治疗后两组的评分分别为17.9（3.3）、23.0（2.5）,差异有统计学意义（t=15.89,P〈0.001）。治疗后两组TESS评分无统计学差异。结论小剂量阿立哌唑可作为增效剂治疗强迫症,8周治疗后未见严重不良反应。     

脑功能磁共振成像研究进展

主要综述fMRI产生的历史、成像原理、成像技术和方法、已经取得的成绩以及将来研究发展的方向等。fMRI产生技术广泛应用的20世纪90年代,主要受快速成像技术的影响,从有创走向无创,从而受到神经、认知和心理科学领域的极大关注。fMRI原理是根据神经元兴奋后局部氧耗与血流增幅不一致,而BOLD效应机制成像,间接显示神经元活动。成像主要采用平面回波成像（EPI）和快速小角度激发（FLASH）技术、二者在时间和空间分辨率上各有优劣。最后几年来,fMRI技术对脑功能的研究已取得了巨大的成绩,估计将在这一领域继续拥有非常重要的地位。将来fMRI可能主要在BOLD效应的生理过程、临床应用以及高场磁体的应用等领域进一步展开。     

Specific CD8+ response discriminates presumed Epstein-Barr virus-related hepatitis and non-alcoholic fatty liver

During intravenous treatment with terlipressin for recurrent gastrointestinal (GI) bleeding, a 50-year-old male with no history of heart disease developed a newly prolonged QT interval and torsade de pointes. Risk factors present for acquired long QT syndrome were mineral dysbalance and a history of alcohol abuse with hepatic impairment. The patient was brought back to a normal sinus rhythm after a single 300-J counter-shock. Terlipressin was discontinued, and the patient's QTc interval subsequently returned to baseline. During 6 weeks of monitoring, arrhythmia did not recur.     

氧气雾化及超声雾化吸入对开胸术后排痰效果的对比研究

目的探讨开胸术后病人有效、简便、舒适的雾化吸入疗法,以促进病人有效排痰,防止术后肺部感染等并发症。方法将开胸术后病人随机抽签分为氧化雾化吸入组和超声雾化吸入组。观察两组日均痰液排出量、日均吸痰次数,及病人呼吸道刺激症状等指标。结果氧化雾化吸入法在减少日均痰吸出量及日均吸痰次数疗效中优于超声雾化吸入法(P>0.05),呼吸道刺激症状及舒适、简便方面明显优于超声雾化吸入法(P<0.05或0.01)。结论氧化雾化吸入法对开胸术后病人有效、简便、舒适的方法。     

“简化复杂概念,提高教学效果”在人体组织学教学中的应用

人体组织学的教学内容大多是对某一具体形态的描述与概括,概念抽象,学生记忆困难。本文结合实践调查,用通俗易懂的例子对国内外教材中的复杂概念进行简化,最终达到提高教学效果的目的。
