花生凝集素受体在鼻息肉组织中的表达及意义

目的 :探讨花生凝集素受体在鼻息肉组织中的表达及意义。方法 :将 2 4例鼻息肉标本及 15例正常鼻窦黏膜标本行凝集素亲合组织化学ABC法染色。结果 :正常鼻息肉黏膜染色基本阴性 ,鼻息肉呈弱染色。N -PNA(预先经神经氨酸酶处理后再进行PNA染色 )染色均显著加深。结论 :从正常鼻窦黏膜到鼻息肉 ,花生凝集素受体的表达发生改变 ,该种改变在鼻息肉的病理机制中可能起着重要作用     

PRENATAL DIAGNOSIS Ⅰ. EARLY DIAGNOSIS OF OPEN NEURAL TUBE DEFECTS BY QUALITATIVE ACETYLCHOLINESTERASE ISOENZYME IN AMNIOTIC FLUID

The measurement of amniotic fluid (AF) acetylcholinesterase isoenzyme (AChEI) is a relatively new method for early diagnosis of open neural tube defects (NTDs). As quantitative methods are of unproven reliability at present, the authors used a high resolving power qualitative method-vertical slab polyaerylamide gel electrophoresis. The benefits of this technique are: simplicity of operation, accuracy, unsophisticated equipment, and easily available reagents. Combined results of 9 NTDs studies revealed that samples from early pregnancy gave more accurate results than those from late pregnancy.     

糖尿病脑内胰岛移植临床初步研究(附三例报告)

本文报告胰岛细胞脑内移植治疗I型糖尿病共3例,分别经过3个月、4个月、6个月的临床观察,其临床症状明显改善或消失,空腹血糖由移植前平均12.38mmol/L下降至7.77mmol/L;3例患者普通胰岛素用量平均每日62.3~u,移植后第21～30天均完全停用胰岛素,其中1例已持续撤离胰岛素治疗达5个月。观察结果提示:胰岛移植物在患者的脑内成活,并具有良好的内分泌功能。     

游离背阔肌皮瓣修复四肢肿瘤切除后创面

我院骨科组于1985年5～10月份为4例患下肢高分化低度恶性肿瘤的病人,在化疗的配合下施行肿瘤局部大块切除,吻合血管的背阔肌肌皮瓣移植修复创面等综合治疗,早期获得了满意的效果.4例病人中有2例患小腿软骨肉瘤,1例小腿脂肪肉瘤和1例髋部纤维肉瘤.背阔肌肌皮瓣较适用于修复软组织缺损大的创面,其大而扁平的肌肉部分几乎能完全覆盖缺损,外形亦常较满意.     

鼻内镜鼻窦手术后应用香菊片对粘膜转归的影响

目的 观察内镜鼻窦手术后应用香菊片对术腔粘膜转归的影陶。方法 Ⅱ型鼻窦炎、鼻息肉患者180例作为治疗组，行内镜鼻窦手术后，在常规辅助治疗基础上加用香菊片口服，并设ll0例Ⅱ型鼻窦炎、鼻息肉患者作为对照组，对比观察术腔清洁时间、术腔上皮化时间及术后复发率。结果 治疗组术腔清洁时间平均为：Ⅰ期1．5周，Ⅱ期1．8周，Ⅲ期2．1周；对照组Ⅰ期2．0周，Ⅱ期2．5周，Ⅲ期3．3周，差异有显著性意义(P＜0．01)。治疗组术腔上皮化时间平均为：Ⅰ期7．0周，Ⅱ期7．5周，Ⅲ期7．8周；对照组Ⅰ期8．0周，Ⅱ期8．4周，Ⅲ期9．0周，差异有显著性意义(P＜0．01)。治疗组术后复发率为4．4％，明显少于对照组7．3％。结论 内镜鼻窦手术后，应用香菊片对鼻腔功能的恢复具有良好的疗效，并能减少复发率，可做为常规药物应用临床。     

溃疡散预防消化性溃疡复发临床观察

目的 :观察溃疡散对消化性溃疡的抗复发治疗的临床效果。方法 :随机将 80例患者分成溃疡散治疗组 (4 2例 )和雷尼替丁对照组 (38例 )并同时观察两组患者治疗前后溃疡复发情况。结果 :治疗后治疗组溃疡复发率明显低于对照组 ,P <0 .0 1,两组对比有非常显著性差异。结论 :治疗组能明显的改善患者临床症状和降低消化性溃疡复发率。     

Cabergoline compared to levodopa in the treatment of patients with severe restless legs syndrome: results from a multi-center, randomized, active controlled trial.

We report the first large-scale double-blind, randomly assigned study to compare two active dopaminergic therapies for Restless Legs Syndrome (RLS), the dopamine agonist cabergoline (CAB) and levodopa/benserazide (levodopa). Patients with idiopathic RLS were treated with fixed daily doses of 2 or 3 mg CAB or 200 or 300 mg levodopa for 30 weeks. Efficacy was assessed by changes in the IRLS (International RLS Severity Scale) and by time to discontinuation of treatment due to loss of efficacy or augmentation. 361 of 418 screened patients (age 58 +/- 12 years, 71% females) were randomly assigned and treated (CAB: n = 178; levodopa: n = 183) in 51 centers of four European countries. Baseline IRLS total score was 25.7 +/- 6.8. The baseline-adjusted mean change from baseline to week 6 in IRLS sum score was d = -16.1 in the CAB group and d = -9.5 in the levodopa group (d = -6.6, P < 0.0001). More patients in the levodopa group (24.0%) than in the CAB group (11.9%, P = 0.0029, log-rank test) discontinued because of loss of efficacy (14.2% vs. 7.9%, P = 0.0290) or augmentation (9.8% vs. 4.0%, P = 0.0412). Adverse events (AEs) occurred in 83.1% of the CAB group and in 77.6% of the levodopa group. In both groups, most frequent AEs were gastrointestinal symptoms (CAB: 55.6%, levodopa: 30.6%, P < 0.0001). This first large-scale active controlled study in RLS showed superior efficacy of cabergoline versus levodopa after a 30-week long-term therapy. Tolerability was found more favorable with levodopa than with cabergoline.     

急进高海拔大鼠肾素-血管紧张素-醛固酮系统的对比性研究

目的：探讨急进高海拔地区机体对低压、低氧环境的适应机制；方法：将海拔10m处的平原大鼠快速带至海拔2261m，再带入海拔3800m处，用放射免疫法测定大鼠血浆肾素、血管紧张素Ⅱ和醛固酮的浓度；结果：随海拔递增①大鼠肾素及血管紧张素Ⅱ含量呈上升趋势，醛固酮浓度逐渐下降，统计学处理有显著性差异；②急进高海拔地区，醛固酮对血管紧张素Ⅱ的反应钝化，使醛固酮处于低水平状态；结论：上述结果提示：急进高海拔，机体对水、电解质的调节会发生变化，这些变化有利于急性高原适应。
