中国内地城市和香港9～18岁学生心肺耐力及肌肉素质的比较研究

为了比较中国内地城市和香港青少年儿童的心肺耐力和肌肉素质，对两地的青少年儿童体质调查数据进行了比较研究。结果发现：内地各年龄组男女生的心肺耐力均优于香港同龄者；香港青少年儿童的肌肉素质除立定跳远外，其他项目的成绩均弱于内地青少年儿童。提示：随着生活水平的提高，应重视青少年儿童对体育活动的参与。     

肾综合征出血热病毒气溶胶的物理稳定性实验研究

本文采用荧光素钠正常鼠脑悬液做模拟示踪物质，对肾综合征出血热病毒气溶胶在空气中的物理稳定性进行了测定，并与其生物稳定性做了比较。结果表明：病毒气溶胶的粒子大小在１ｕｍ左右，它随气溶胶的胶龄增长而减少，且其分散度变窄。初始气溶胶的物理回收率及其各胶龄的物理存留率均明显地高于它的生物回收率和生物存活率。本文还就肾综合征出血热病毒气溶胶的物理稳定性和生物稳定性，对本病空气传播的影响进行了讨论。     

Caring and cancer nursing: framing the reality using selected social science theory

Caring and cancer nursing: framing the reality using selected social science theory Despite the recent interest in caring for both academic and clinical nursing, the theoretical basis of this concept may appear somewhat elusive as the research and debate vary widely in their focus. As a result, the available literature may fail to consider the specific contextual issues which characterize caring as it is understood across different health care settings. Consideration of theory from disciplines close to nursing, it is suggested, may be useful in understanding the nature of such 'real world' caring. In this discussion the concept of caring within cancer nursing is explored by drawing on a number of social science and nursing sources. It is known that cancer provokes unique caring demands for nurses practising in this area. By examining the context of cancer, it is argued that effective caring deserves to be recognized as an important clinical variable which can influence a diverse range of issues such as patient satisfaction or therapeutic outcome. It is suggested that other nursing specialisms should also explore the psychosocial dimensions of caring in relation to their own role.     

分散染料在染色涤纶上固着状态的探讨

利用X-射线衍射、DSC热分析和光学行为的测量,对三个分散染料(C.I.分散红225、167,C.I.分散蓝73)在染色涤纶纤维上的固着状态进行了研究。结果表明:这些染料均不以晶体状态固着在纤维上,所以染色纤维的色光与这些染料晶型的颜色没有关系。

Influence of handedness on calcaneal ultrasound: Implications for assessment of osteoporosis and study design

Calcaneal ultrasound has been increasingly studied for its potential in the assessment of osteoporotic fracture risk. The accuracy of such an assessment is, in part, dependent on the reproducibility of the measurement. This study examines the impact of handedness on ultrasound measurements [broadband ultrasound attenuation (BUA) and velocity of sound (VOS)] in the calcaneus. Two hundred and sixty-four subjects (57 men and 297 women) aged 51.1+13.6 years (mean ± SD) were studied. For each subject, calcaneal ultrasound measurements were performed on both heels with a McCue CUBA ultrasound densitometer. Right-handed dominance (94.7%) was determined by structured interview. In men, BUA measurements were significantly higher on the dominant side: mean difference 4.1±1.5 dB/MHz (mean ± SD;p=0.009), equivalent to 4.2+1.5% and more than 4 times the average rate of annual change in BUA. The difference between sides was greater in young (<50 years) than old men (>50 years). Among the women, the difference was not statistically significant (0.7±0.9 dB/MHz;p=0.4); however, it was significant in younger women (20–30 years) (99±4 vs 90±4 dB/MHz,p=0.01). By contrast VOS did not differ between sides in either men or women irrespective of age. Within-subject standard deviation of BUA was 9.8 dB/MHz for men and 8.6 dB/ MHz for women and the component due to right and left difference was 8.4 dB/MHz for men and 6.9 dB/MHz for women. This variability of BUA between right and left heels could increase the false-positive rate by up to 28% for a cut-off of 2 SD below the mean. These data indicate that variation between left and right heel measurements of BUA is higher than that of random error measurements, particularly in men and younger, presumably more physically active subjects. Although VOS measurements were not side dependent, in the smaller number of studies examining VOS and fracture risk, VOS appears to have a weaker predictive power than BUA. Clinical and epidemiological studies involving calcaneal BUA measurements should standardize the side measured to either the dominant or non-dominant heel, to reduce within-subject variation and increase their power.     

The disability rating index: An instrument for the assessment of disability in clinical settings

The purpose of this study was to evaluate an instrument for assessment of physical disability, mainly intended for clinical settings, the Disability Rating Index (DRI). Healthy persons (n = 1092), both white and blue collar workers, and patients (n = 366) with different levels of physical capacity, were assessed. Most of the patients (n = 303) underwent rehabilitation programmes for neck/shoulder/low-back pain but some (n = 47) were arthritis patients waiting for hip or knee replacement surgery, or wheelchair patients with multiple sclerosis (n = 16). The reliability was investigated by test-retest studies, intra- and inter-rater and internal consistency studies. Five construct validity tests were carried out: a discrimination study; a converging validity test; a test for sensitivity to small alterations in health status; and two correlational validity tests. Correlation of the self-reported DRI to the actual performance in similar activities was carried out. Responsiveness was tested by correlation of the DRI before/after replacement surgery for arthritis. The test-retest correlations were 0.83–0.95 in the studies, including correlation of different versions. The intra- and inter-rater reproducibility was 0.98 and 0.99 respectively. The Kruskal-Wallis test in the discrimination study yielded p < 0.0001. More than 90% of the respondents completed the questionnaire correctly. Correlation of the DRI to the Functional Status Questionnaire was 0.46. The responsiveness was excellent, p = 0.0001. The DRI proved to be a robust, practical clinical and research instrument with good responsiveness and acceptability for assessment of disability caused by impairment of common motor functions.
