双眼视差视觉诱发电位与立体视觉的关系初探

作者采用双眼视差视觉诱发电位（VEP）记录了18名正常人和9名斜视患者（立体盲），结果正常人视觉刺激VEP P₁₀₀振幅明显高于非视差刺激者；斜视患者视差刺激与非视差刺激VEP P₁₀₀振幅差异无显著性；正常人视差刺激VEP P₁₀₀振幅增加的幅度值[（DSA-NDA）/NDA]明显高于斜视患者。 （中华眼底病杂志，1992，8：10-13）

Parkinson''''s Disease and Smoking: An Integral Part of PD''''s Etiological Study

INTRODUCTION Parkinson抯 disease (PD), a debilitating neurodegenerative disorder, is featured with bradykinesia, resting, muscular rigidity, gait disturbances, and postural reflex impairment[1]. PD is rare before age of 50 years, but it increases dramatically with older ages, with peak onset occurring during the age of 70-85 years. In the United States, prevalence of PD in all age groups is approximately 150 per 100 000 and is roughly 30 per 100 000 at age of less than 50 years and 800 …     

肠内营养支持治疗高龄老年脑血管病人的疗效分析

目的：探讨肠内营养支持在治疗高龄老年脑血管病中的重要性。方法：回顾性调查肠内营养支持治疗高龄老年脑血管病人的疗效及半年、1年、2年的生存率。结果：肠内营养支持治疗高龄老年脑血管病人时，鼻饲及综合治疗优于单纯经口服营养支持。结论：在治疗高龄老年人脑血管病人时应采取鼻饲肠内营养支持加药物治疗效果比较理想。     

Beneficial Effects of Short-term Vasopressin Infusion during Severe Septic Shock

Background: Septic shock is associated with vasopressin deficiency and a hypersensitivity to its exogenous administration. The goal of the current study was to determine whether short-term vasopressin infusion in patients experiencing severe septic shock has a vasopressor sparing effect while maintaining hemodynamic stability and adequate end-organ perfusion.

Methods: Patients experiencing septic shock that required high-dose vasopressor support were randomized to a double-blinded 4-h infusion of either norepinephrine (n = 11) or vasopressin (n = 13), and open-label vasopressors were titrated to maintain blood pressure. To assess end-organ perfusion, urine output and creatinine clearance, gastric mucosal carbon dioxide tension, and electrocardiogram ST segment position were measured.

Results: Patients randomized to norepinephrine went from a median prestudy norepinephrine infusion of 20.0 [mu]g/min to a blinded infusion of 17.0 [mu]g/min at 4 h, whereas those randomized to vasopressin went from a median prestudy norepinephrine infusion of 25.0 [mu]g/min to 5.3 [mu]g/min at 4 h (P < 0.001). Mean arterial pressure and cardiac index were maintained in both groups. Urine output did not change in the norepinephrine group (median, 25 to 15 ml/h) but increased substantially in the vasopressin group (median, 32.5 to 65 ml/h;P < 0.05). Similarly, creatinine clearance did not change in the norepinephrine group but increased by 75% in the vasopressin group (P < 0.05). Gastric mucosal carbon dioxide tension and electrocardiogram ST segments did not change significantly in either group.     

黑人妇女健康调查中自我报道子宫平滑肌瘤的年龄特异性发病率

目的:子宫平滑肌瘤是美国黑人妇女中一个有代表性的主要公共健康问题,但该高危人群的年龄-发病率曲线关系的相关资料却很少。本研究对生活在美国的非洲-美洲妇女展开大规模的队列研究,探讨自我报道子宫平滑肌瘤的总体及年龄特异性发病率。方法:资料来自黑人妇女健康调查,一项正在进行的59000例黑人妇女参加的前瞻性队列研究,受试者来自美国各地,年龄21～69岁(出生年份相同,如1995年)。从1997年3月至2001年3月,随访了22895例无前期子宫平滑肌瘤诊断的绝经前妇女。采用Poisson回归法分析自我报道子宫平滑肌瘤总体及年龄特异性发病率和95%CI…     

视网膜下液对培养的人视网膜色素上皮细胞、神经胶质细胞及成纤维细胞生长的刺激作用

目的:研究视网膜下液(subrefinal fluid,SRF)对增殖性玻璃体视网膜病变(proliferativeVitreoretinopathy，PVR)的多种细胞增殖的影响. 方法；采用直接细胞计数和_³H-TdR掺入率测定DNA合成两种方法观察28例孔源性视网膜脱离患者SRF对培养的人视网膜色索上皮(retinal pigment epithelium，RPE)细胞，视网膜神经胶质(retinal glia，RG)细胞及成纤维细胞(flbroblast，FB)生长刺激作用． 结果：所有标本均具有刺激RPE细胞、RG细胞及FB增殖和DNA合成能力，增殖率范围分别在基线上52.5%～233.3%、36.4%～177.8%、55.4%~277.8%之间．SRF促细胞增殖串在三种细胞间比较无显著差异。 结论：SRF具有促多种细胞增殖的能力，推测SRF中含有促细胞增殖的活性物质。 （中华眼底病杂志，1996，12：233-235）     

视网膜脱离术后复发的原因与处理

分析57例视网膜脱离术后视网膜不复位26例，复位后再脱离31例，手术失败的原因，发现原裂孔未闭、新裂孔形成和增殖性玻璃体视网膜病变是视网膜脱离术后未复位或再脱离的三大原因，并分析了造成这些原因的因素，讨论了有关再手术的问题。 （中华眼底病杂志，1993，9：164-165）
