糖尿病急性并发症合并呼吸衰竭的救治

糖尿病急性并发症起病急骤，短时间内易并发多脏器功能衰竭，尤其以呼吸衰竭多发，是患者死亡的主要原因。早期识别呼吸衰竭的发生，是抢救成功的关键。本文分析了2001年1月至2005年2月我院收治的38例糖尿病并发急性呼吸衰竭病人的早期诊断与治疗情况。

伴有食道静脉曲张的早期肝癌的治疗

肝细胞肝癌伴有食道静脉曲张的治疗,对外科医生仍是一个难题,因为大多数此类病人存在进展期肝硬化。这类病人常随着肿瘤进展发生食道曲张静脉破裂出血,而肝脏手术也常导致短暂的门脉高压。为了提高肝脏手术的疗效,预防食道曲张静脉破裂出血是重要的。目前硬化剂治疗作为对食道静脉曲张的治疗已被广泛接受,逐渐取代手术治疗。作者报告22例肝癌伴有食道静脉曲张的病人,经过积极肝切除术,术中行断流术、围手术期行硬化剂治疗或先后行两种治疗,对照37倒小肝癌不伴食道静脉曲张病人行肝切除术的疗效。病例和方法:研究组(A组)22例,肝癌伴有食     

头孢吡肟治疗慢性阻塞性肺疾病急性加重期不同疗程的疗效比较

目的比较两种不同疗程的抗菌治疗对COPD急性加重期的疗效。方法将60例COPD急性加重期住院患者随机分为2组,分别予以头孢吡肟针10 d和5 d的抗菌治疗。比较2组患者在入院时、第7天和第12天的临床表现、肺功能和动脉血气变化情况。结果2组入院后第7天的临床表现、肺功能和动脉血气指标较治疗前无显著变化(P均>0.05),第12天各指标较治疗前均显著改善(P均<0.05),但组间比较无显著性差异(P>0.05)。结论短疗程抗菌治疗是COPD急性加重期的有效治疗手段。     

三种去神经法对清醒大鼠动脉压力感受性反射功能的影响

目的：测定急、慢性去主动脉神经（ＡＤ）、去颈动脉窦神经（ＳＤ）、同时去主动脉和窦神经（ＳＡＤ）后大鼠动脉压力感受性反射对血压控制（ＡＢＲ－ＢＰ）和心动周期控制（ＡＢＲ－ＨＰ）的影响。方法：测定ＡＢＲ－ＢＰ采用阻断动脉压力感受性反射传出通路前后，比较机体对去氧肾上腺素升压反应面积差异的方法，所得数值与改良的Ｓｍｙｔｈ方法测定的ＡＢＲ－ＨＰ值进行比较。结果：（１）大鼠ＳＡＤ后ＡＢＲ－ＨＰ为零，且代偿不明显；而ＡＢＲ－ＢＰ约为３０％，且代偿明显；（２）ＳＤ后ＡＢＲ－ＢＰ与ＡＢＲ－ＨＰ无显著差异，而ＡＤ和ＳＡＤ后ＡＢＲ－ＢＰ的作用显著大于ＡＢＲ－ＨＰ的作用。结论：（１）大鼠的ＡＢＲ－ＨＰ传入冲动全部来自于主动脉弓和颈动脉窦的压力感受器，而ＡＢＲ－ＢＰ传入冲动大部分来自于这两处的感受器；（２）主动脉神经和窦神经感受传入在ＡＢＲ－ＢＰ中的作用是相当的，并有明显的相互代偿；而在ＡＢＲ－ＨＰ中，主动脉神经的作用比窦神经重要，其代偿能力也比窦神经显著。     

COMBINED INTRAOPERATIVE ILIAC ARTERY STENTS AND FEMORO-POPLITEAL BYPASS FOR MULTILEVEL ATHEROSCLEROTIC OCCLUSIVE DISEASE

Objective. To review our preliminary experience and evaluate our early results of a combined intraopemtive iliac angioplasty and stenting with infrainguinal revascularization in multilevel atherosclerotic occlusive disease. Methods. From July 1999 to April 2000, intraoperative iliac angiOplasty and stenting combined with simultaneous femoro-pepliteal bypass were pedormed on 12 lower extremities of 10 patients suffering from multilevel athemsclemtic occlusive disease. There were 8 men and 2 women, average 72 years. The indicationsf or procedures included disabling claudication in 3 and rest pain in 7 patients. Results. Eleven iliac angioplasty and stem procedures combined with simultaneous 9 femoro-popliteal by-pass and 3 femoro-femoral-popliteal bypass were performed in 12 limbs of 10 patients. Angioplasty and stem placement was technically successful in all patients. One contralateral femoral-popliteal bypass was failure after femoro-femoral-popliteal bypass. There were no additional instances of procedural or postoperative morbidity or mortality. Mean follow-up was 5 months (range 1 -10 months). During the follow-up period, one femoro-infrapoplitealgraft became occluded after 7 months and above-knee amputation was required. The cumulative primary patencyrate of stented iliac arteries, femoro-femoral bypass grafts and femoro-popliteal bypass grafts were 100% (11/11), 100% (3/3) and 90. 9% (10/11) in the follow-up period, respectivdy. The amputation rate was 8. 3%(1/12). Conclusions. Intraoperative iliac artery PTA and stent placement can be safely and effectively pedormed simultaneously with infrainguinal revascularization for multilevel atherosclerotic occlusive disease by skilled vascular surgeon, using a portable C ann fluoroscopy in the operating room. Furthermore, iliac artery PTA and stenting was valuable adjunct to distal bypass either to improve inflow and outflow, or to reduce the extent of traditionalsurgical intervention, and also, any angioplasty and stenting-related complications can be immediately corrected as well.     

高分子化合物在卫生杀虫剂中的研究应用

高分子化合物是指分子量很大(一般在2万以上)但没有一个特定值,分子内部缺少活性官能团而表现为无完整晶体、难溶于常规溶剂、没有明显的熔点、不导电、呈化学惰性的一类物质,其中分子内有重复性化学结构的又称聚合物〔1〕。这类物质很多,天然的如植物胶质类(阿拉伯胶、白及胶、西黄芪胶等)、动物类(明胶、骨胶原等),半合成的如淀粉及衍生物类(可溶性淀粉、氧化淀粉等)、纤维素类(甲基纤维素、乙基纤维素等),人工合成的如聚某烯类(聚乙烯、聚丙烯等)等。其中天然高分子化合物具有易降解、无残毒等优点〔2-3〕。由于高分子化合物具有分散、增…
