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.     

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.     

人血液酪氨酸蛋白激酶的研究——(Ⅲ)1—异丙基—6—氨基—噻吩骈[3,4—d]嘧啶—2,4—二酮对人淋巴细胞膜TPK活性的抑制作用

文报道了人工合成的1—异丙基—6—氨基—噻吩骈〔3,4—d〕嘧啶—2,4—二酮对人淋巴细胞膜TPK活性的抑制作用,IC_(50)约为300μmol/L。动力学实验结果表明,该化合物对TPK的抑制作用与ATP呈竞争性,而与多肽底物Poly(Glu—Ala—Tyr)_(6;3:1)呈非竞争性。放射自显影结果进一步证实了该化合物对TPK的抑制作用。     

都匀地区布依族正常胎儿外形测量

有关胎儿的外形测量,国内外虽有报导,但不尽相同,都匀地区尚未见有关数据,为研究少数民族地区不同发育阶段胎儿的生长发育规律,我们于1992年10月—1994年12月对都匀地区116例不同胎龄的布依族正常胎儿进行有关的外形测量,结     

烧伤患儿恐惧心理的护理

小儿烧(烫)伤是日常生活中十分常见的意外伤害,它不仅导致患儿身体遭受损害,还给患儿心理造成极大的恐惧感,导致了生活方式的改变。近年来,随着医学模式由生物医学模式向心理、社会、生物医学模式的转变,推广“以人为本,以病人为中心”的新型医疗模式,心理护理也得到了人们青睐     

子宫动脉栓塞术治疗子宫腺肌症后妊娠1例

子宫腺肌症是由于子宫内膜的腺体和基质异位生长于子宫肌层使子宫体积弥漫性增大的疾病。临床表现为痛经、月经过多、子宫增大和不孕。它是一种妇科常见病，其发病率呈上升趋势，国内报道为16．7％，国外为8．8％～31．0%。该病的治疗一直较为困难，传统多以子宫切除为主，药物治疗为辅。但药物治疗疗效欠佳，易反复且不良反应大；而生育年龄的年轻患者切除子宫，不但丧失生育能力，导致内分泌失调，亦在心理上产生不良影响，     

黄芪注射液治疗幽门螺杆菌相关性胃炎的临床研究

目的:探讨黄芪注射液对幽门螺杆菌(HP)相关性胃炎的临床疗效。方法:将62例幽门螺杆菌相关性胃炎患者随机分为两组,治疗组和对照组各31例。对照组给予常规治疗(用法莫替丁、阿莫西林胶囊及复方灭滴灵片治疗4周),治疗组在对照组治疗基础上给予黄芪注射液20ml加入10%葡萄糖液250ml中静脉点滴,每日1次,4周为1个疗程,测定两组幽门螺杆菌阴转率,观察两组的临床疗效。结果:治疗组HP阴转率明显高于对照组(P＜0．05),治疗组临床疗效优于对照组(P＜0．05)。结论:黄芪注射液能提高幽门螺杆菌相关性胃炎的治愈率。     

汶川大地震后送伤病员病情特点及救治要点

2008年5月12日发生的汶川里氏8．0级地震造成37万余人受伤，近90％为肢体创伤病员。其中，10％-15％患者伴有颅面、胸腹部等处创伤。我院于2008年5月23日及28日分两批收治47名震区空运伤病员，其中骨科伤病员41例。本文针对我院接收的41例骨科伤病员的入院时病情特点、治疗措施及原则等作一简要总结。
