急性期介入低频重复经颅磁刺激对缺血性脑卒中患者上肢运动功能的影响

目的 探讨急性期介入低频重复经颅磁刺激(rTMS)对缺血性脑卒中患者上肢运动功能的影响。 方法 选取急性期缺血性脑卒中患者82例,按照随机数字表法将其分为对照组和试验组,每组41例,研究过程中每组均脱落1例,最终对照组和试验组各纳入40例。2组患者均给予常规康复治疗,试验组予以低频rTMS治疗,对照组予以rTMS假刺激治疗。治疗前、治疗4周后,采用Fugl-Meyer量表（FMA）上肢部分、Wolf运动功能评价量表（WMFT）、改良Barthel指数（MBI）、运动诱发电位(MEP)潜伏期和波幅评价2组患者的上肢运动功能。 结果 治疗前,2组患者FMA评分、WMFT评分、MBI评分、MEP波幅和潜伏期比较,差异均无统计学意义（P＞0.05）。治疗4周后,2组患者的FMA、WMFT、MBI评分和MEP波幅均较组内治疗前明显改善（P＜0.05）,且试验组治疗4周后的FMA［(39.20±7.36)分］、WMFT［(54.43±9.28)分］、MBI［(62.18±9.53)分］、MEP波幅［（0.74±0.08）mV］改善较对照组显著（P＜0.05）。 结论 急性期介入低频rTMS可改善缺血性脑卒中患者的上肢运动功能,提高日常生活活动能力。

手术前后补硒对结直肠癌患者免疫功能的影响

目的　研究手术前后服用酵母硒对结直肠癌患者免疫功能的作用。方法　1998 年3 月～1999 年3月,将我院的40 例大肠癌患者,随机分成对照组和治疗组,分别给予一般酵母和酵母硒(600μg/d) 持续2 周,观察治疗前后血硒水平、T 细胞亚群和免疫球蛋白,以及细胞因子αTNF 的变化。结果　补硒后,血硒由0 .79 ±0 .17μmol/L上升到0 .99 ±0 .23μmol/L,P< 0 .05 ;CD4 由24 .09 ±4 .10 % 上升到27 .95 ±4 .91 % ,CD8 由20 .18 ±2 .48 % 上升到23 .09 ±4 .47 % ,P< 0 .05 ;血清中Ig M 从83 .7 ±22 .37mg % 上升到103 .69 ±35 .49mg % ,P< 0 .05 。结论　手术前后给大肠癌患者服用酵母硒可明显地提高其血硒水平,改善机体的免疫功能并增强抗肿瘤的能力。     

舰艇环境对舰员心理功能和神经行为的影响

探讨封闭型舰艇环境对舰员心理功能和神经行为的影响。方法 采用微机化神经行为评价系统和症状自评量表对封闭型水面舰艇舰员进行了测试,并以开放型水面舰艇舰员为对照。结果 封闭型舰艇人员符号译码成绩明显低于开放型舰艇人员,并出现类似“空调病”的症状。结论封闭型舰艇环境能危害舰员的心理健康,负离子浓度低为重要的环境因素,应改进通风。     

应用脉冲多普勒估测右心室dp／dtmax方法的评价

目的通过动物实验及临床研究评价右心室射血期肺动脉脉冲多普勒频谱参数估测右心室收缩功能的可行性。方法6条健康犬及25例先心病患儿。1.在右心室正性肌力及改变前后负荷干预下,观察实验犬血流频谱最高速度（Vp）、加速时间（AT）、平均加速度（Am）及Vp2／AT等肺动脉射血期脉冲多普勒参数与右心室dp／dtmax的关系。2.测算先心病患儿上述各肺动脉射血期血流频谱参数并与心导管造影术中右室dp／dtmax测值比较。结果1．实验犬中仅Vp及Vp2／AT在右心室正性肌力及前后负荷干预下始终与右室dp／dtmax呈高度相关。2先心病患者肺动脉血流Vp、Am及Vp2／AT与右心室dp／dtmax成非常显著相关。结论右室Vp及Vp2／AT可用于右空心肌收缩力的估测。     

Periventricular- intraventricular hemorrhage in the premature infant- A historical perspective

The objective of this chapter is to trace the evolution of intraventricular hemorrhage in the premature infant highlighting the importance of the germinal matrix, a critical role for cerebral blood flow changes in the genesis of hemorrhage, clinical factors that increase the bleeding risk, and potential preventative strategies. In 1976, neuropathological studies demonstrated capillary rupture within the germinal matrix as the precursor of hemorrhage. In 1980, introduction of cranial ultrasound facilitated diagnosis of intraventricular hemorrhage. In 1979, loss of cerebral autoregulation in sick newborn infants was demonstrated. In the 1980’s, studies demonstrated the importance of intravascular factors in provoking hemorrhage. In 1983, the association of cerebral blood flow velocity fluctuations and subsequent hemorrhage was demonstrated. In 1994, antenatal steroids use to accelerate lung development was recommended. This was associated with an unanticipated reduction in hemorrhage. In the mid 1990’s early indomethacin administration was associated with a reduction of severe hemorrhage.     

IgG antibodies, chronic bronchitis, and pulmonary function values in farmer's lung patients and matched controls

We measured IgG antibody levels against eight different microbes in farmer's lung (FL) patients an average of 14 years after the first diagnosed episode of FL and in matched controls. The study population consisted of 87 FL patients and 81 control farmers, matched by age, sex, and smoking habits. Clinical studies included the measurement of IgG antibody levels against Absidia corymbifera, Aspergillus umbrosus, A. fumigatus, Humicola grisea, Saccharopolyspora rectivirgula, Penicillium brevicompactum, Rhodotorula glutinis, and Thermoactinomyces vulgaris, in addition to spirometry, pulmonary diffusing capacity (DL(CO)), and the evaluation of chronic bronchitis. Median IgG antibody levels were two or more times higher in FL patients than control farmers against Ab. corymbifera, S. rectivirgula, and T. vulgaris (P<0.001). Against A. fumigatus, H. grisea, and R. glutinis, FL patients also had significantly higher antibody levels. FL patients often had positive antibody titers against several microbes, whereas control farmers usually had a positive titer against one or two microbes. A positive association between IgG antibody levels and chronic bronchitis and DL(CO) was observed in FL patients, but not in control farmers. It is suggested that the high antibody levels noted in FL patients were due not only to high exposure but also to individual sensitivity to environmental microbes.
