联合抗青光眼手术治疗不易控制眼压青光眼的研究

采用板层下巩膜床双咬切、睫状体剥离合并睛状体上腔植入硅橡胶条的抗青光眼联合手术治疗不易控制眼压的青光眼46例52眼，其中继发性青光眼27眼，原发闭角青光眼10眼，原发开角青光眼6眼，先天、青少年型青光眼7眼，虹膜角膜内皮综合征2眼。手术总有效率达94％。本术式具有小梁切除、睫状体剥离、睫状体扁平部引流的功能。作者认为用硅橡胶条作植入物，比异体或自体组织作植入物更为理想。

五型病毒性肝炎的暴露因素与临床表现的比较

比较急性病毒性肝炎患者感染打危险因素，同时比较五型肝炎的症状和体征。连续收集急性病毒性肝炎患者血清２９３份，用ＥＬＩＳＡ法检测了五型肝炎病毒的病原学指标，并进行了流赞美同学调查。暴露因素：丙肝的肠道外暴露外明显多于甲肝；甲肝和戊肝有较高的“甲肝”患者接触史；乙肝，丙肝和丁肝有高的“乙肝”接触史，与甲肝，戊肝相比差异显著。     

Determinantion and evaluation of antisperm antibodies and seminal immunosuppressive material in recurrent aborting couples

Circulating antisperm antibodies (AsAb) and immunosuppressive material in seminal plasma (SPIM)were determined by solid-phase enzyme staining assay and anticomplement test respectively in 686 patients with abortion (including 285 couples) . 241 fertile couple served as control. It's found that the positive rate of AsAb in infertile patients was significantly higher than that in fertile control,being 36.6% vs 3.3% (P<0.001). AsAb was even more offen detected in recurrent aborting patients. Male patients whose spouses aborted 2-6 fetuses had significantly less SPIM than control, sperm count and sperm motility were also significantly decreased. But the incidence of pyospermia was significantly greater than that in control. It is concluded that AsAb and SPIM have played an important role in the development of recurrent abortions.     

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     

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.
