屈膝过程中的胫股运动特性分析

本文采用三维位移测量方法，测试１０例离体人膝标本的胫股关节三维运动特性。发现屈膝过程中，胫股运动也具有典型的三维运动特点。其中在屈膝初期的３０°内，胫骨内旋最明显并伴有胫骨内翻现象，平均内旋８°，内翻６－７ｍｍ，膝关节完全伸直时胫股扣锁使膝关节稳定，屈曲时胫股“解锁”使膝关节松弛，具重要的临床意义，同时提示，在解释传统的胫股扣锁现象时不应遗漏伴随发生的胫骨内／外翻现象。     

Tension neck and evaluation of a physical training course among office workers in a bank corporation

The purpose of this study was to investigate the effects of a physical training course in a group of patients (n=74) suffering from chronic tension neck. All participants in the course were employed by a bank corporation in Helsinki, Finland. A comparable control group (n=77) consisted of office workers with tension neck from the same bank corporation who did not attend any training course. The outcome was analysed 6 months after the course. Pain and disability in the neck and shoulder region did not vary significantly between the group which participated in the training course and the control group. The experimental group had increased the amount of physical workout compared to the control group (83.7% vs 69.0%, P = 0.0448). Also, regarding the frequency of relaxation and stretching exercises the two groups differed significantly: the experimental group had continued to perform exercises more often (P= 0.0434). The frequency of sick leave days did not significantly differ between the groups, but the office workers in the experimental group had more periods of extended sick leave (> 10 days) and the controls had more frequent short sick leaves. The experimental group did increase their physical workout significantly compared with the controls, but no differences were detected regarding pain and disability. In order to gain more benefit more attention should be paid to the educational part of the training courses in order to enhance the patients'self-care abilities. Also, strategies to alleviate psychosocial problems and organized relaxation exercises could decrease muscle tension in the neck in office workers.     

广西射击运动员血清脂质水平分析

目的：了解射击运动员高脂血症的发生情况和可能的引发因素，为预防高脂血症提供依据。方法：对从事专业训练半年以上，无急慢性疾病的53名省级优秀射击运动员进行膳食调查和血清脂质水平检测。结果：运动员的高脂血症检出率为28．3％，全部为高甘油三脂血症；膳食中 运动员除了摄入维生素B1、B2不足和维生素A缺乏外，其他各类营养素基本能满足机体需要，属基本合理膳食。结论：以抗阻训练和静力运动为运动特征的射击运动，可能会对机体血脂代谢产生不利的影响。     

女性飞行学员高空飞行生理生化耐受能力研究

为从高空缺氧耐力训练前后生理、生化角度探讨中国女飞行员驾驶战斗机的可行性,在地面模拟高空缺氧及高空飞行训练前后行心电图、心率、血氧饱和度、血压、血尿酸(BUA)、肌酸激酶(CK)、血红蛋白(Hb)、乳酸(BLA)、肌酐(Cr)和天冬氨酸转氨酶(AST)测定,并与男飞行学员的测定结果比较.发现男女飞行学员的心电图、心率、血氧饱和度、血压、Cr、CK、BUA和AST均无显著性差异;女飞行学员在高空耐缺氧Hb代偿反应高于男飞行学员(P<0.05),而BLA水平低于男飞行学员(P<0.05).认为中国女飞行学员在生理生化耐受能力上能胜任飞战斗机.

Head Start Teaching Center: Differential Training Effects for Head Start Personnel

Driven by research findings regarding the positive relationship between training and enhancement of services, as well as literature on adult learning, the New England Head Start Teaching Center (NEHSTC) was created in 1992 to test the efficacy of participatory, hands-on training. The purpose of this paper is to examine the outcome evaluation results from 4 years of training at the NEHSTC, 1 of 14 federally funded sites, as well as to discuss the implications for delivering this type of participatory training throughout Head Start. Findings suggest that the NEHSTC was successful in implementing high quality, participatory training within the context of an ongoing Head Start program. Head Start staff who participated in the NEHSTC trainings demonstrated gains in knowledge, skills, and expertise compared to similar Head Start employees who did not receive training. Results also reveal a sustained effect of training over time, with NEHSTC participants continuing to demonstrate enhanced knowledge and skills 6 months after training. Similar positive outcomes of training were found for staff with varying levels of experience and holding different Head Start positions. Thus the participatory, hands-on training implemented by the NEHSTC was found to produce positive and lasting outcomes for diverse Head Start staff. An effective and cost efficient model of training Head Start personnel is particularly relevant and timely as Head Start strives to establish universal quality and expansion of services in the 21st Century. The findings are also relevant for improving the quality of all early care and education programs.     

老年髋部骨折术后患者康复需求程度与康复状况调查

目的了解老年髋部骨折术后患者康复需求程度、需求满足度与康复状况的关系.方法上门随访82例老年髋部骨折术后患者家庭康复现状和康复需求情况.结果康复需求10个维度中他人支持、康复信息及功能训练指导位居前3位;需求程度与生理功能、躯体功能和社会功能有关(P＜0.05,P＜0.01);与髋关节功能评分中的疼痛程度、上楼梯、穿鞋袜和行走距离4个方面有关(P＜0.05,P＜0.01).结论出院后定期给予针对性的康复训练指导和健康教育是患者迫切的需求;康复需求程度高者,相应需求满足率低,其生活质量及髋关节功能恢复应成为干预的重点.     

经鼻蝶窦手术动物模型神经内镜手术训练

目的建立一种活体动物的神经内镜经鼻蝶手术模拟训练方法。方法选择大鼠，建立一套训练计划，完成内镜图像导引下的内镜操作，电凝止血、冲洗和吸引、活检等神经内镜经鼻蝶手术的基本技巧。结果利用大鼠颅脑进行模仿内镜经鼻蝶手术，如在内镜图像导引下操作内镜的方法；熟悉内镜系统、电凝系统、冲洗和吸引设备的使用；熟悉了神经内镜经鼻蝶手术的步骤。结论作为神经内镜实验室训练的重要组成部分，通过利用大鼠颅脑进行模拟神经内镜手术，训练者可以从中获得神经内镜操作基本技巧的练习。
