高原老年人和红细胞增多症病人返回平原后记忆功能的“脱适应”研究

15例离退休健康男性老人和9例红细胞增多症男性病人返回平原后,记忆功能改变的特点:①两组受试者除5例成绩下降外,苏州记忆成绩高于西宁成绩(p<0.01)。②记忆成绩降低现象存在于20%左右的人中。③高原缺氧和返平原脱适应均主要影响短时记忆。     

不经胸食管钝性剥离拔脱术的临床应用

应用不经胸食管钝性剥离拔脱术治疗26例咽下癌与高位食管癌,效果良好,术后5例发生开发症,其中颈部吻合口痿3例,暂时性咳呛1例,腹部切口局限裂开1例。手术死亡率7.6%(2/26)。介绍了手术方法,对不经胸施术、胃体缝缩、颈部食管胃Gambee氏吻合法应用进行了讨论。     

健康和病变人声带振动特性声门图

本文用多功能声门图仪测定了健康受试者(男46名,女34名)和不同喉病患者(男134名,女87名)声门图的波形及其特征参数。根据测出的正常声门图及其参数分布研究了恶性喉病变、声带麻痹、喉内关节病变、功能性声门发声障碍、声带息肉、声带小结、喉炎和早期喉病的临床声门图表现及其与声带振动模式变异之间的关系,并探讨了上述病变声门图的鉴别诊断指标和用声门图对喉病手术治疗、药物治疗和功能治疗的疗效进行定性和定量评价。研究结果证实:声门图方法能准确、定量、灵敏地反映声带振动模式及其变异;在喉病诊治中具有重要的应用价值。     

Epithelial cysts of the spleen]

The Authors report a case of epithelial cyst of the spleen-observed in a 25 years old woman. After remembering the nomenclature and pathogenetic hypothesis, they consider clinical patterns of this rare disease of the spleen which is usually found in children and young adults. The Authors discuss pathological findings, diagnostic aids, especially non-invasive imaging. They also suggest considering the cysts in diagnosis of the diseases of the spleen and splenectomy as a treatment of choice.     

侧脑室注射东莨菪碱和酚妥拉明对幼兔分辨学习的影响

目的 探讨东莨菪碱和酚妥拉明对幼兔分辨学习的影响。方法 将30只比利时纯种幼兔从生后13日龄随机分为三组：东莨菪碱组、酚妥拉明组和生理盐水对照组，观察不同日龄各组幼兔的分辨学习能力。结果 幼兔分辨学习的正确反应一般始于生后15日龄。侧脑室注射东莨菪碱对16日龄以前幼兔分辨学习无明显影响，对17日龄以后幼兔分辨学习产生明显抑制作用。侧脑室注射酚妥拉明对13—23日龄幼兔分辨学习均有明显抑制作用。结论 幼兔生后发育过程中学习能力的发展具明显的阶段性，其原因可能与神经递质系统的发育成熟有关。     

A department of general surgery using the Diagnosis Related Groups (DRGs) system. Evaluation of the case series]

DRGs system allows the grouping in a single grad-bag code of a number of similar surgical procedures carried out in patients homogeneous for age, physical status, complication and so on with similar costs. Therefore this grouping method is useful for payment to hospitals. The Authors have coded with DRGs the surgical activity of a general surgery staff during a year to verify the image that DRGs bears. Seven hundred diagnoses of dismission were related to operated on patients while one hundred twenty seven were related to patients treated with medical therapy. The DRGs more numerous were 290, 258, 198, 162, related with thyroidectomy, mastectomy, cholecystectomy and herniorrhaphy.     

The telephone survey: a methodological strategy for obtaining information

Studies have shown that students and the general population have little knowledge about nursing schools and the nursing profession. This study investigates the extent to which a sample of the population of Brazil is aware of the existence of nursing schools, and how they have obtained this information. Data were collected by telephone interviews. The sample consisted of 326 subjects whose telephone numbers were taken from the telephone book. Analysis showed that 73% of the subjects were aware of the existence of two nursing schools in the city; however, 65.03% did not know the names of these schools. Direct communication with friends and family, as well as indirect communication by television and advertising, were the sources of information mentioned by those questioned.     

应用单克隆抗体检测肺癌病人外周血中T细胞亚群

本文应用单克隆抗体检测33例原发性肺癌病人治疗前后外周血中T淋巴细胞亚群变化。结果提示:肺癌病人外周血中T细胞亚群明显有别于正常人,主要表现为T_H细胞降低和T_S细胞升高以及T_H/T_S比值明显倒置。短期观察结果表明,肺癌病人外周血中T_S细胞持续升高和T_H/T_S比值持续降低者,预后不良。临床检测T细胞亚群变化及它们的动态变化可作为判断宿主抗肿瘤免疫功能状态、病情发展和预后的敏感指标。
