胸部X线与CT诊断支气管结核的临床价值

目的分析胸部X线及CT影像征象在支气管结核临床诊断中的价值和意义。方法收集本院经病理及电子支气管镜证实为支气管结核105例，对照其胸部X线与CT表现进行回顾性分析。结果105例患者中，胸部X线显示伴有肺内结核灶77例，气管狭窄、肺叶不张分别为51例和49例，未见异常表现17例。胸部CT扫描对气管狭窄及肺叶不张检出率明显提高，分别为72例和61例，且能观察到气管内壁情况及狭窄或阻塞后肺野情况，伴肺内结核灶79例，无异常改变只有8例。结论提高对支气管结核的影像学认识，能有效地提高临床诊断准确率。     

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.     

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。

激光多普勒技术测定组织血流及其在高温治癌研究中的意义

应用激光多普勒血流仪测量比较津白Ⅱ号小鼠三个部位皮肤的血流,观察HDZ对血流的影响,评价了HDZ的体内热增敏作用。结果发现,同一小鼠不同部位的血流是不同的,同一部位的连续6天结果无何区别。但同部位小鼠间的血流差别可达1倍以上。提示了预测放、化、热疗的疗效时,监测个体血流的前后变化有重要意义。2.5mg/kg以上的HDZ可以明显降低血流75％左右。HDZ与高温联合应用时对肿瘤显示了热增敏效应。
