前列腺摘除术后膀胱颈狭窄的防治

膀胱前列腺摘除术后采用改良荷包缝合活结法，治疗了３０例前列腺增生患者，经过３个月－１年的随访，尚未见发生膀胱颈狭窄者。经膀胱前列腺摘除术的关键不仅在于避免和减少术中、术后出血，而且要防止术后膀胱颈部狭窄。我们采用改良式荷包缝合活结法取得了较好的疗效。

避孕措施与细菌性阴道病关系的研究

目的：探讨避孕措施与细菌性阴道病（BV）的关系，为预防BV、指导选择避孕措施提供依据。方法：对某医院妇科门诊接受计划生育服务的育龄妇女非选择性地进行BV筛检。以筛检出的267例BV患者为病例组，其余478例未患BV且无BV史的妇女为对照组进行病例对照研究。结果：与未采用避孕措施者比较，单因素logistic回归分析显示：BV与IUD有正关联，而与避孕套、口服避孕药（OC）无关联。经婚姻状况、性卫生、性行为习惯调整后，BV与IUD的关联仍有统计学意义（OR=2．364，95％C1：1．216～3．620），但与OC及避孕套使用无关。同IUD使用者比较，BV与避孕套使用呈负关联，调整后的OR=0．299（95％C1：0．158～0．566）；BV与OC使用间无关联。结论：使用IUD与未采用避孕措施者比较可能增加BV发生的危险，而避孕套使用者发生BV危险低于IUD使用者。无论从避孕还是预防BV角度，避孕套均是一种较好的选择。     

经岩下窦栓塞治疗海绵窦部硬脑膜动静脉瘘

海绵窦部硬脑膜动静脉瘘（cavernous sinus dural arteriovenous fistulas,CSdAVFs）多见于中老年女性,自发起病,其病因尚存争议,目前认为与静脉窦内的炎症和血栓形成等有关.CSdAVFs的治疗主要依靠血管内栓塞治疗的方法,具体有经动脉和静脉两种途径.与CSdAVFs复杂的供应动脉相比,作为引流静脉的海绵窦及其相关的静脉系统,其结构要简单得多.     

坚持中西医并重方针办好多功能型中医院

全国卫生工作会议多次提出坚持中西医并重方针，发展中医药，是对中医药工作的高度重视。中医药事业作为我国卫生事业中独具特色与优势的重要组成部分，也必将更加蓬勃发展，同时也为我们中医药的工作者指明了今后发展的方向。如何结合中医专科医院的工作实际，办好适应新形势下适应市场经济的发展，使中医骨伤专科医院越办越好，我们的体会是：     

节育环嵌顿子宫壁的诊断、处理及预防

我国采用宫内节育环避孕，已有几十年的历史了。通过大量临床实践证明，它是一种有效、简便、经济、取出后不影响生育能力，深受广大妇女欢迎的避孕措施。但它还存在着一定的缺陷即：嵌顿子宫壁。往往造成取环困难，如处理不当，就会给上环妇女增加很大痛苦，同时节育环嵌顿也使其失去避孕作用。据笔者观察，较为常见的有：节育环嵌于子宫内膜层、肌层、浆膜层。现结合病例探讨其诊断处理方法及预防措施，进一步提高节育环避孕的效果，提出个人意见供讨论。     

兔动静脉短路环法诱导组织工程骨支架材料血管生成的初步研究

Objective To compare the effects of 2 vascular carriers, arteriovenous loop and arteri-ovenous bundle, on inducing angiogenesis in coral scaffold of vascularized tissue-engineered bone in animal models.Methods Thirty-six adult male New Zealand rabbits were randomized into 2 even groups.In group A, an arteriovenous loop (AVL) was formed by microsurgical anastomosis at the proximal ends between the femoral poptiteal artery and vein, and placed in the circular side groove of the coral block (6 mm × 8 mm × 10 mm) .In group B, flow-through vessels bundles of both femoral artery and vein were placed in the side grooves of the coral block.All the implants in 2 groups were wrapped by a micro-porous expand-ed-polytetrafluoroethylene (ePTFE) membrane, and fixed subcutaneously by suturing.Evaluation methods included gross morphological observations, histological examinations, India ink perfusion and vascular casting after 2, 4, 6 weeks.The density of blood vessels was analyzed by the statistical software SPSS 10.0.Results All the corals were encased by newly formed fibrovascular tissues in 2 groups.Ink-stained vessels distributed the surfaces and side grooves, and invaded the interspaces of corals.The degree of vascularization increased over the course of experiment.Blood vessel density demonstrated a significant continuous increase between 2 and 6 weeks after implantation in group A.The mean value of blood vessel density in group A (2 weeks 276.60±4.67, 4 weeks 517.20±10.66, 6 weeks 707.00 ±11.87) was significantly higher than in group B (2 weeks 153.60 ±7.16, 4 weeks 269.40±6.80, 6 weeks 279.20±6.53) (P <0.01).Vascular casting showed that in group A, significant blood vessels sprouted from all areas of the loop, espe-cially at the entrance of the arteriovenous pediele where the small tubes were densely interconnected.In group B, however, no blood vessels sprouted from the arteriovenous bundles and only some small vessels grew from the entrance and exit.Conclusions A vascularized coral model can be constructed by inserting an ar-teriovenous loop or an arteriovenous bundle, useful in vascular bone tissue engineering.The former, however, have stronger abilities to induce angiogenesis than the latter.     

胎儿垂体前叶激素释放的超微结构研究

本文通过5例水囊引产、不同胎龄胎儿垂体前叶超微结构研究,从形态上证明前叶激素的释放有多种方式:1.胞吐和错位胞吐;2.以胞质小块释放入血窦:有突起的细胞将突起伸入血管间隙,末端与细胞脱离形成含分泌颗粒的胞质小块,经内皮窗孔进入血窦;3、越膜渗出:分泌颗粒内容物跨越颗粒膜和细胞膜渗出细胞;4.有脑颗粒的排出;5.血窦内皮的吞噬和转运作用。[关     

硬膜外自家血充填疗法防治腰穿后头痛的体会(附12例报告)

我院自1968年至1984年共施行连续硬膜外麻醉15000人次,其中穿破硬膜12人次(0.08％)。采用硬膜外自家血充填法,防治刺破硬膜后并发头痛取得良好效果,现介绍如下。自家血液配制:以10ml注射器抽蒸溜水4ml。再抽自家血6ml,充分摇动,使红细胞溶解,避免血液凝固形成小的凝血块。
