Statistical analysis of the factors affecting the outcome of extradural haematomas: 115 Cases

Summary 115 traumatic extradural haematoma cases who were treated surgically at Cerrahpasa Medical Faculty Neurosurgery Department between 1987 and 1992 are evaluated.When factors affecting the outcome were examined, a strong correlation was found between the result andGlasgow coma scale (GCS) (p<0.00001). The existence of a fracture, the interval between onset of haematoma symptoms and intervention and the existence of an intracerebral haematoma together with contusion accompanying intradural haematoma, affect the outcome in a negative direction. There was no statistical correlation between the outcome and the age of patient, localization of the haematoma and aetiology.     

实质器官移植术后血浆IL-18、IL-10、IL-4检测在人巨细胞病毒感染中的意义

目的 探讨实质器官移植术后血浆中白介素18（IL－18）、白介素10（IL－10）、白介素4（IL－4）水平的检测在人巨细胞病毒（HCMV）感染中的意义。方法 对24例实质器官移植受者，用免疫组化法监测HCMV抗原血症。然后采用ELISA法测定血浆中IL－18、IL－10及IL－4的水平。结果 HCMV抗原阳性组IL－18的水平高于阴性组（P＜0.01），IL－10及IL－4的水平低于阴性组（均P＜0.05）。结论 血浆IL－18的水平可作为预测移植患者HCMV感染的一个有效指标，IL－10及IL－4的水平则可作为患者HCMV感染后体内免疫抑制程度的监测指标之一。     

硬膜外腔阻滞对胸部手术应激反应的影响

目的 观察硬膜外腔阻滞对胸部手术应激激素和细胞因子的影响。方法20例食管癌手术病人,随机分为两组,每组10例,即全麻复令硬膜外腔阻滞(GEA)组和全麻(GA)组,分别测定麻醉诱导前、手术2h、手术4h、术毕、术后1d及术后3d的血浆去甲肾上腺素、肾上腺素、血清促肾上腺皮质激素(ACTH)、皮质醇、C-反应蛋白、IL-6及IL-10的水平。结果 血浆去甲肾上腺素和血清皮质醇GEA组术中术后无显著改变,但GA组术毕和术后1d显著升高(P<0.05),术后3d恢复至术前水平,组间比较前者有显著差异(P<0.05)。两组血浆肾上腺素、IL-10术中术后均无显著变化。两组血清ACTH、IL-6及CRP术中术后均显著升高(P<0.05),组间比较无显著差异。结论 硬膜外腔阻滞可以减轻胸部手术的应激反应。IL-6是较CRP更灵敏的反映组织损伤的炎性指标。     

高频灰阶超声鉴别良恶性胸肌淋巴结

目的:评价灰阶超声在鉴别良、恶性胸肌淋巴结中的应用价值.材料和方法:研究对象为43枚乳癌患者的胸肌淋巴结,其中16枚为转移性胸肌淋巴结、27枚为非转移性胸肌淋巴结;另有19枚乳腺良性病变患者的胸肌淋巴结和22枚正常者的胸肌淋巴结作为对照组.使用仪器为HDI-3000型彩色多普勒超声诊断仪,配备5～12MHz宽频控头.运用超声测量胸肌淋巴结的长径、轮廓形态、长径-厚度比、髓皮质厚度比,作为鉴别良、恶性胸肌淋巴结的参数,比较良、恶性胸肌淋巴结在形态学上差异.结果:良、恶性胸肌淋巴结的长径、轮廓形态、髓皮质厚度比无显著性差异;恶性淋巴结长径-厚度比(1.7±0.4)明显低于良性淋巴结(2.0±0.5),P＜0.05.结论:灰阶超声在鉴别良、恶性胸肌淋巴结中具有一定的应用价值.     

病毒白细胞介素-10转基因在造血干细胞中的表达

目的　观察逆转录病毒转病毒白细胞介素 10 (vIL 10 )基因在体内的表达。方法　用MSCVneo vIL 10重组体在体外转导CBA (H 2 K)小鼠的造血干细胞 (HSCs) ,给经致死照射(90 0rads)的 2 0只同基因CBA(H 2 K)小鼠注入经MSCVneo vIL 10转染的HSCs ,2× 10 6HSCs/只。酶联免疫吸附测定 (ELISA)、逆转录 聚合酶链反应 (RT PCR )、Westernblot分析vIL 10的表达。结果　移植MSCVneo vIL 10转染HSCs的 2 0只小鼠 ,移植后 8周用ELISA检测 ,其中 15只小鼠血清的vIL 10浓度为 :2 70～ 13 40ng/L ,5只小鼠血清的vIL 10为阴性。 12周后有 2只小鼠vIL 10测不出 ,13只小鼠长时间表达vIL 10达 6个月。对照组小鼠血清vIL 10均为阴性。RT PCR和Westernblot证实小鼠的器官均有vIL 10的mRNA和蛋白的表达。结论　逆转录病毒能有效地将vIL 10基因导入造血干细胞并在体内长时间表达。     

Sleep complaints and their relation with drug treatment in patients suffering from Parkinson's disease.

The aim of this research was to quantify sleep problems in patients suffering from Parkinson's disease by means of the new Parkinson's Disease Sleep Scale (PDSS) and to correlate such problems with the possible influence of current drug treatment. A total of 70 patients (36 men and 34 women) with a diagnosis of Parkinson's disease were enrolled. Their mean age was 69.7 +/- 8.2 years, and duration of disease was 7.4 +/- 4.8 years. All patients completed the PDSS and the Unified Parkinson's Disease Rating Scale (UPDRS Parts I-IV). Drug consumption and doses were registered. The mean score on the PDSS scale was 109.23 +/- 19.75 and on the UPDRS III scale was 25.24 +/- 11.35. The lowest scores were obtained in Item 3 (sleep fragmentation): 5.53 (2.46); and in Item 8 (nocturia): 5.75 (2.91). There was a weak correlation between the PDSS and UPDRS III (cc = -0.355, P = 0.003), PDSS and UPDRS I (cc = -0.272, P = 0.02), and PDSS and UPDRS IV (cc = -0.416, P < 0.001). Motor conditions, mental state, and drug complications influence sleep quality. Although this effect was significant, it was not of a great magnitude. Dopaminergic drugs did not increase daytime sleepiness. As a whole, sleep quality in patients who took dopaminergic agonists did not differ from that of patients who took levodopa in monotherapy.
