股骨颈骨折几种闭合复位方法的评价(译文)

在股骨颈移位骨折的治疗中,试用了7种不同的闭合复位方法。其中Whitman's法在骨折床台上进行,正常肢体外展,患肢由屈曲牵引至完全伸直位后,维持牵引并外展到与对侧肢体相称位,单髋人字石膏外固定(1914年)。 Leadbetter's法也在骨折床台上进行。将患肢髋部屈曲90°,沿大腿轴线行手法牵引。同时股骨干稍内收,患肢缓慢行环形活动至外展、内旋位,患肢向下降至骨折床台面时,行跟掌试验以验证是否完全复位(1933年)。 Bozan's法利用骨折床台使双下肢维持在伸直位,大绷带放置在患肢髂嵴部位,小绷带放置在患肢腹股沟皱襞最高点处实施牵引。然后整个患肢极度内旋,在维持侧方牵引的同时,患肢外展并轻度过牵(1934年)。     

临床全身性抽搐发作状态下的动态脑电图分析

本文对７２例全身抽搐发作的患者且２４小时脑电图监测期间有临床发作的动态脑电图进行分析，年龄１个月￣６２岁，其中１个月￣１４岁６７例，结果显示：在临床发作状态下，ＡＥＥＧ均显示痫性放电，且有五种波形。其中４２例仅在临床发作时有痫性放电，而发作间歇期背景活动均正常。根据临床及ＡＥＥＧ波形特点，确诊阵挛性发作３８例，强直－阵挛性发作１３例，复杂性部分发作１３例，局限性发作泛化７例，强直发作１例。我们的研     

生长激素在肝硬变门脉高压低蛋白血症手术前的应用研究

目的：研究生长激素（rhGH)对肝硬变门脉高压低蛋白血症患者手术前的治疗价值。方法：肝硬变门脉高压抑行脾切除、门奇静脉断流手术患者60例，Child分级B级，随机分为rhGH治疗组30例，对照组30例。rhGH组术前5d每天皮下注射rhGH 4IU，对照组给予安慰剂生理盐水。两组术前均行相同肠外营养支持。测定治疗前、治疗后3d、4d、5d血浆白蛋白、球蛋白、前白蛋白及空腹血糖。结果：rhGH组治疗后3d前白蛋白较治疗前及对照组明显升高（P＜0．05），治疗后4d、5d仍维持较高水平；治疗后5d白蛋白较治疗前及对照组明显升高（P＜0．05）。rhGH组患者一般情况改善，生活质量提高。对照组白蛋白、前白蛋白无明显变化。两组空腹血糖、球蛋白无明显改变。结论：rhGH联合肠外营养支持对纪正肝硬变门脉高压低蛋白血症患者术前低蛋白状态，改善生活质量有良好疗效，由于rhGH起效慢，应早期、足量、足疗程应用。     

The use of 6-flavor Rehmannia decoction with additives in the prevention of ototoxic deafness induced by gentamicin in guinea pigs]

The purpose of this study is to discuss the effects of the Chinese medicine six-flavor Rehmannia Decoction with additives on preventing deafness induced by gentamicin (GM) in guinea pig by means of testing the thresholds of Preyer's reflex (PR) cochlear microphonic potential (CM), action potential of the auditory nerve (N1) and scanning electron microscope of inner ear (SEM). The results showed that the medicine is effective in reducing the ototoxic effect of GM on inner ear.     

Neuromuscular block with vecuronium reduces the rapidly extracted auditory evoked potentials index during steady state anesthesia

PURPOSE: During clinical monitoring, vecuronium appeared to reduce the rapidly extracted auditory evoked potentials index (A-line ARX index or AAI) to some extent. A prospective and randomized study was designed to analyze this phenomenon. METHODS: Forty adult patients undergoing elective surgery were studied. After tracheal intubation, anesthesia was maintained with an end-tidal isoflurane concentration (F(ET)ISO) of 1.0% for 20 min, then a 10-mL dose of either vecuronium 0.05 mg*kg(-1), 0.1 mg*kg(-1), 0.2 mg*kg(-1) or saline was administered in a randomized, double-blind design. The AAI and bispectral index (BI(hx)) were monitored throughout the study and analyzed off-line. RESULTS: BI(hx) was unaltered after the administration of saline or vecuronium. The mean of the averaged (per patient) AAI values recorded from two minutes to ten minutes after the administration of saline or vecuronium 0.05 mg*kg(-1) did not differ significantly from the corresponding mean recorded from 15 min to 20 min after F(ET)ISO maintained 1.0% (P = 0.678, 0.169), however after the administration of vecuronium 0.1 mg*kg(-1) or 0.2 mg*kg(-1), AAI was reduced from 18.3, 18.0 to 14.8, 13.4 (P = 0.016, 0.017). CONCLUSIONS: Neuromuscular block with vecuronium reduces AAI in patients during steady state anesthesia without surgical stimuli, while BI(hx) is unaltered. The cut-off values of AAI for events should be determined according to the level of neuromuscular blockade when monitoring the depth of anesthesia/sedation.     

口服维生素K1对新生儿维生素K缺乏诱导蛋白的影响

目的 探讨口服维生素K1（VK1）对新生儿VK缺乏症诱导蛋白Ⅱ（PIVKA－Ⅱ）的影响及口服VK1的最佳剂量。方法 随机将101例足月新生儿分为口服VK1 2.5mg组、5mg组及对照组三组，出生时均采集脐血，用酶联免疫吸附法测定PIVKA－Ⅱ含量，3d后复查三组新生儿血PIVKA－Ⅱ含量。结果 PIVKA－Ⅱ≥2mg/ml人数2.5mg组由8例降至4例，5mg组由11例降至2例，对照组由11例降至8例。经统计学处理，2.5mg组与5mg组比较P＞0．05；口服VK1组与对照组比较P＜0．05。结论 PIVKA－Ⅱ的变化与口服VK1剂量的差异无显著性。
