头颈部肿瘤合并糖尿病的围手术期处理

目的探讨头颈部肿瘤合并糖尿病患者围手术期的处理方法.方法从2001年1月～2003年6月我科收治的头颈部肿瘤450例,对其中33例合并糖尿病患者使用胰岛素控制血糖的资料进行分析.结果 28例无并发症发生,切口感染2例,腮腺漏2例,心律失常1例,无围手术期死亡.结论对于合并糖尿病的头颈部肿瘤患者,合理使用胰岛素控制血糖是围手术期处理的主要方法,是安全渡过围手术期的重要保证.     

The role of HLA‐DQβ1 alleles in susceptibility to rheumatoid arthritis

Aim: Rheumatoid arthritis (RA) is the most common chronic inflammatory erosive joint disease with the worldwide distribution of approximately 0.5–1.0%. Etiology of RA is not exactly known but immunologic and genetic factors play an important role in the pathogenesis of the disease. Genetic factors such as human leukocyte antigens (HLA) are responsible for many autoimmune diseases; therefore we decided to look for a correlation between RA and the presence of HLA‐DQβ1 alleles as possible genetic markers. Methods: Genomic DNA from the whole blood samples of 25 patients with RA and 86 normal individuals as control group were extracted by salting out method. The genomic DNA was amplified by polymerase chain reaction‐sequence specific primer (PCR‐SSP) technique. HLA‐typing was done by this method after optimizing the PCR reaction for each allele. In this procedure seven serological subclasses of HLA‐DQβ1 can be detected. Results: Comparing the results between the patients and controls show a significant increase in the frequency of HLA‐DQ8 (*0302, *0305) alleles in RA patients. The P‐values were 0.007 and the relative risk for these alleles was evaluated higher than 1. Conclusions: The results suggest that DQ8 is the dominant HLA‐DQβ1 allele that is associated with susceptibility to RA in north‐eastern Iran.     

失眠症患者睡眠质量的主观评估与多导睡眠图参数对比分析

目的 探讨失眠症患者对睡眠质量的主观评估,并通过对多导睡眠图(PSG)睡眠参数的定量分析,对失眠症患者的睡眠状况进行客观评估,进一步将二者进行对比分析.方法 对失眠症患者和健康人各100例运用匹兹堡睡眠质量指数问卷(PSQI)进行评定,并分别进行多导睡眠图的整夜睡眠描记,次日晨起后询问夜间睡眠情况.结果 失眠症组PSQI各成分得分及总分均高于对照组,差异有统计学意义(P＜0.01).与对照组相比,失眠症组的睡眠潜伏期(min)延长(失眠症组43.69±11.54,对照组16.01±10.44)、总睡眠时间(min)减少(失眠症组314.65±91.89,对照组446.41±77.81)、睡眠效率降低(失眠症组64.51%±18.59%,对照组91.32%±3.58%)、快眼动睡眠时间(min)减少(失眠症组33.26±15.61,对照组93.21±21.63),差异有统计学意义(P＜0.01).失眠症组对总睡眠时间的评估较PSG检测值显著减低、对睡眠潜伏期的评估较PSG检测值显著增高,自我评估与实际睡眠情况不一致.结论 失眠症患者睡眠质量较差.失眠症患者的PSG各睡眠参数有特征性的改变,利用PSG检查发现失眠症患者对失眠情况的主客观评估不一致,存在过高估价睡眠潜伏期和过低估价睡眠时间的倾向.     

Geste antagonistes in idiopathic lower cranial dystonia.

Geste antagonistes, or sensory tricks, are well described in focal dystonia affecting the neck, hand, and face. Improvement in dystonic movements is typically maintained while the trick is performed, but disappears when the geste ends. We investigated the phenomenological features of geste antagoniste maneuvers in 19 patients with idiopathic lower cranial dystonia who were prospectively evaluated over a period of 6 years. Of the 19, 10 were men, mean age of onset was 49.8 years, and the most commonly involved lower cranial area was the jaw (10 patients). In most patients, dystonia was task-specific. Taking advantage of the improvement with a sensory geste, we manufactured oral appliances that mimicked the geste in 8 patients, and 3 continue to use it.     

中西医结合治疗缺血性脑血管病临床疗效观察

目的 回顾性分析中西医结合治疗缺血性脑血管病的疗效。方法 对126例缺血性脑血管病患者，在早期西医溶栓、抗凝、降低血液粘度、扩张血管和促进脑细胞代谢等治疗基础上，结合中医辩证施治治疗。结果 42例瘫肢肌力恢复达V级；48例肌力≥Ⅳ级，言语流畅；27例生活能基本自理，可依杖散步，肌力≥Ⅲ级：9例与治疗前对比肌力提高Ⅰ～Ⅱ级，但生活仍不能自理。结论 在西药治疗基础上，结合益气活血中药调理可显著提高患者的疗效。
