肾综合征出血热少尿期中药结肠透析疗法的临床研究

肾综合征出血热(HFRS)是由汉坦病毒引起的以小血管和毛细血管广泛性损害为病理基础，以发热、出血、肾损害为临床特点的传染性疾病，传染性强、病情凶险、病死率高，在我地区有间歇流行趋势。临床通常分为发热期、低血压期、少尿期、多尿期、恢复期，尤以少尿期为本病的极期。我院1992年10月～1996年10月间．对本病大流行时的少尿期病人采取综合治疗，配合自拟通关煎结肠透析．取得了满意疗效，现介绍如下。     

计算机针灸辅助教学与显示系统

计算机辅助教学（Computer—Aided Instruction）简称为CAI。目前在各个学科已广泛应用,针灸计算机辅助教学与显示系统较传统教学具有很大的灵活性,为提供各种教学环境,对开发学生智力,提高学生自学能力,发展现代化的形象教学,具有较大的价值。 1、系统概述 “计算机针灸辅助教学与显示系统”是在super XT系列微机上开发的CAI系统。整个系统为树形结构,按功能划分为若干模块。“系统”运行时采用多级菜单,逐级进入各功能模块或逐级返回上一级菜单,人机对话功能强,用户可按显示屏幕上的提示很方便地使用。     

一种安全的胆囊切除方法及其解剖学基础(附1382例分析)

目的:总结一种安全的胆囊切除方法,并分析其解剖组织学理论根据.方法:对本院1984年1月～2002年1月1382例胆囊切除术患者的资料进行回顾性分析.结果:患者中无胆管损伤、胆瘘及术中大出血,无一例死亡.结论:术中应始终警惕胆管损伤和出血的可能性:细心辨别胆囊管、胆总管和胆囊动脉三者关系,切除胆囊时从胆囊浆膜与肌层间少血管区解剖出胆囊,遇有索状组织即予结扎,以减少胆瘘出血的机会.

金属内支架置入联合三维适形放射治疗肝癌合并门静脉癌栓

Objective To study the clinical efficiency of metallic stent implantation in combination with three-dimensional conformal radiation therapy in the treatment of hepatocellular carcinoma (HCC) pa-tients with portal vein tumor thrombus. Methods 22 cases of HCC patients with portal vein tumor thrombus were devided into 2 groups: 10 patients (group A) recieved stent implantation in combination with conformal radiation therapy, 12 patients (group B) recieved stent implantation and transcatheter arterial chemoembolization. The adverse reactions, and liver function before and after treatment were compared between the two groups. The stent patency rate at 4, 6 and 12 months and the survival rate at 3, 6 and 12 months were followed up. Comparison of liver function was analyzed by Wilcoxon signed rank test. Compari-son of stent patency rate curves and survival curves was analyzed by Log rank test. Results The portal vein catheterization was successful in all the patients. The stents were successfully implanted by transhepatic portal vein approach, and portal vein stenosis was re-opened. There was no abdominal hemorrhage in all the patients, but there were symptoms of abdominalgia, fever, nausea, vomiting and flatulence of varying de-grees after interventional operation, and these symptoms were relieved by symptomatic treatment in one week. All patients in group A completed the treatment. Ⅰ-Ⅱ degree gastrointestinal tract reactions occurred in 3 cases, Ⅰ-Ⅱ degree myelosuppression occurred in 2 cases, and they were all completely relieved after treatment. The stent patency rate at 4, 6 and 12 months was 90%, 70%, 30% in group A; and 50%, 25%, 16.7% in group B (P < 0.05). The survival rate at 3, 6 and 1 2 months was 100%, 80%, 30% in group A and 91.7%, 41.7%, 16.7% in group B (P < 0.05). Conclusion Stent implantation combined with three-dimensional conformal radiation therapy is a good treatment for hepatocellular carcinoma with portal vein tumor thrombus and causes less damage to liver.
