目的:观察低分子肝素治疗不稳定性心绞痛病人的疗效。方法:不稳定性心绞痛病人80例,随机分为两组:治疗组(40例),给予阿司匹林和抗心绞痛常规治疗下,加低分子肝素5000U,每12h一次,连用14d,对照组(40例),给予阿司匹林和抗心绞痛常规治疗。结果:治疗组与对照组在改善心绞痛症状及心电图表现方面总有效率分别为87.5％、70.0％(P<0.05),两组均未发生心脏事件。结论:低分子肝素是一种有效安全的治疗不稳定性心绞痛的药物。     

机械通气在心脏疾患中的应用

目的探讨机械通气在心脏疾病中的应用价值.方法对16例因各种心脏疾病所致严重心力衰竭和14例致命性心律失常引起的心跳骤停患者采用机械通气治疗.观察通气前后患者的心率、呼吸、血压、氧饱和度和血气分析等指标的变化,并与60例非心脏疾病(以呼吸衰竭为主)的患者比较机械通气时间、脱机成功率、死亡率.结果16例急性左心衰组患者心率和呼吸明显减慢(P＜0.05),血气分析各指标明显改善.急性左心衰组、致命性心律失常组、呼吸衰竭组的脱机成功率分别为81.3%、35.7%、41.6%;死亡率为18.8%、64.3%、58.3%.结论及时进行机械通气不仅适宜于呼吸衰竭的抢救,也有利于心力衰竭的治疗,但必须采用适当的通气策略.     

小腿后部各区穿支间的关系与皮瓣设计

Objective To study the anastomotic relationships of perforators in each zone of the poste-rior leg and design perforating flaps for clinic. Methods Six fresh cadavers underwent a whole body, intra-arterial injection of a lead oxide and gelatine preparation. The posterior part of leg is divided into upper, mid-die and below equal parts, Observe topography of the perforating branches in every district by layer, and mea-sured their location, diameter, course, branches and anastomosis pattern. Radiographs of tissue specimens were digitally analyzed. Results There were 13 perforators that diameter≥ 0.5 mm, the average external diameter was 0.8 mm. The areas of each perforator supplied was average 38 cm2. Perforators from popliteal artery was identified an area 4 cm wide, around the intersection of two lines, a line drawn between the medial and lateral epicondyles of the femurs, and the midline of posterior leg. The areas of the every perforator sup-plied was 55 cm2. These vessels were large in diameter and create multiple true anastomoses with the perfora-tors from the posterior tibial artery or fibular artery. Perforating branches were small in the below part, a long perforator chain comprised of two to three perforators accompanies the Achilles tendon. Conclusion The perforator flaps deviced by perforators from the posterior leg may be transplanted to the lower limbs and the other part of the body. The perforators located in the middle zone of the leg are larger. Free posterior tibial or peroneal perforator-based flaps are reliable, relatively large, and have thin flaps. The upper and lower zones were the larger donor site for the proximal or distally pedicled perforator flap harvest.     

防治球虫病的常用中草药研究进展

由于化学药物防治球虫病存在易残留、毒性较大等缺点,而免疫预防尚存不足,所以,开发中草药资源具有良好的前景。中药不仅可以预防和控制球虫病,还可以提高鸡的免疫力,从根本上提高抗病力,并具有不易产生耐药性、毒副作用     

高甘油三脂血症与胰岛素抵抗及糖代谢异常的关系

探讨高甘油三酯及糖代谢异常之间的关系。方法将７１例高ＴＧ血症患者按照空腹血ＴＧ增高的程度分为高ＴＧⅠ组和Ⅱ组，做葡萄糖耐量和胰岛素释放试验，计算岛素敏感性指数，并以３２例正常血ＴＧ者作对照。采用多因素回     

基于ERD/ERS脑电信号的智能化功能电刺激系统的设计

设计一套基于事件相关同步电位(Event related desynchron ization,ERD)和事件相关去同步电位(Event related synchronization,ERS)脑电信号反馈控制功能电刺激仪系统。当大脑想象残肢运动中,出现ERD/ERS脑电信号,经过特征提取和特征分类转换为控制命令去触发功能电刺激系统,实现对相应残肢的电刺激。实验结果成功实现了对残肢的电刺激。     

恶性肿瘤患者手术麻醉过程中异丙酚的抗氧化作用

目的：观察异丙酚对恶性肿瘤患者术中血浆过氧化脂质（P－LPO）、红细胞过氧化脂质（E－LPO）和血浆超氧化物歧化酶（P－SOD）、红细胞超氧化物歧化酶（E－SOD）活性的影响。方法：将择期行腹部恶性肿瘤手术患者随机分为异丙酚组（23例）。麻醉诱导时静脉予异丙酚1mg/kg,术中以3－5mg/(kg.h)静脉维持;对照组（20例）,诱导及术中未予异丙酚,监测其手术麻醉过程中P－LPO、E－LPO和P－SOD、E－SOD的变化。结果：异丙酚组气管插管后1h、气管拔管后与麻醉诱导前比较,P－LPO、E－LPO均显著下降（均P＜0．05）,P－SOD`E-SOD则均显著上升（均P＜0．05）;与同期对照组比较,P－LPO、E－LPO均显著下降（均P＜0．01）,P－SOD、E－SOD则均显著上升（P＜0．01）,结论恶性肿瘤患者术前存在氧自由基代谢紊乱,临床剂量的异丙酚能有效清除氧自由基,有显著的抗氧化作用。     

山东省潍坊东部地区精神分裂症1号染色体基因扫描研究
