浙江省台州市路桥区从业人员乙肝病毒标志物检测的调查分析

目的：了解路桥地区2004年至2006年之间,从业人员健康人群HBsAg、HBsAb的阳性率及大、小三阳所占的比例。方法：对32 490人来体检的健康人群进行乙肝三系二对半检测,采用酶联免疫法（ELISA）测定HBsAg、HBsAb、HBeAg、HBeAb、HBcAb,按不同性别、城区与乡镇之间、两年之间进行比较。结果：不同性别之间HBsAg、HBsAb的阳性率无显著性差异。城区与乡镇之间HBsAg、HBsAb阳性率有显著性差异。两年之间HBsAg的阳性率有下降趋势。大小三阳的比例在各组之间也各不相同。结论：健康人群的乙肝病毒携带率比例偏高,易感者多,相关部门应督促乙肝疫苗的注射,减少乙肝发病率。

导管射频消融治疗飞行员快速心律失常临床分析

目的探讨导管射频消融（RFCA）在治疗飞行员多种快速性心律失常中的安全性及临床应用价值，探讨飞行员快速性心律失常的航空医学鉴定标准。方法对13例快速性心律失常的飞行员进行了电生理（EP）检查，特发性室性心动过速（VT）1例，频发室性期前收缩（VE）2例，阵发性心房纤颤（AF）1例，房室折返性心动过速（AVRT）5例，房室结折返性心动过速（AVNRT）3例，房性心动过速（AT）1例。对其中12例采用RFCA治疗。结果RFCA即刻成功率为100％，全组无并发症发生。1例房性心动过速未行导管射频消融治疗。所有飞行员术后地面观察6个月后，返院进行随访复查，同时进行飞行鉴定。12例导管射频消融治疗，术后6个月24h动态心电图、12导联心电图检查和食道电生理检查均未检测到术前的同型快速性心律失常发作，延迟成功率为100％，医学鉴定合格。1例AT仍有发作，飞行不合格。结论对于飞行员快速性心律失常进行导管射频消融治疗是一种安全、有效的治疗方法。心脏电生理检查应作为飞行员快速性心律失常医学鉴定的主要指标之一。

胃镜检查与幽门螺杆菌感染关系的初步探讨

本文用前瞻性连续检测方法，对２６９例患者作胃粘膜ＨＰ检测，且同步对消毒前后的胃镜、有关器械和操作者手套采样，作ＨＰ检测。结果发现，消毒前镜端（含弯曲部）、活检钳、清洁刷、器械管道插口和操作者手套采样标本的ＨＰ阳性率分别达６９．５１％、７３．６０％、８１．６２％、８７．７３％和９７．７２％。目前常规的清洗消毒虽能清除ＨＰ对胃镜的大部分污染，但还存在一些易忽视的环节，这可能在检查中引起医源性感染，应予高度重视。     

Interobserver variation in the evaluation of neurological signs: observer dependent factors.

Introduction - Interobserver variation among four observers in evaluation of eight selected neurological signs was investigated. Material & methods - Two hundred and two consecutive unselected inpatients were examined by two senior neurologists and two trainees, all without knowledge of the neurological case history. The signs examined were: anisocoria, jerky eye movements, facial palsy, elbow extension force, finger-nose test, Barré sign, knee jerk, and extensor plantar reflex. Observed agreement rates and kappa coefficients were calculated in order to compare the interobserver variability among neurologists and trainees, and to evaluate differences in the interobserver variability between signs. Results - Observed agreement rates varied from 0.80 to 0.95 for neurologists and from 0.65 to 0.98 for trainees. For neurologists kappa coefficients ranged from 0.40 to 0.67 and for trainees from 0.22 to 0.81. The neurologists had higher kappa values than the trainees in 5 signs, but this difference was only statistically significant for jerky eye movements. For the individual signs the observed agreement rates were between 0.50 and 0.93 for all four examiners combined, and overall kappa values varied from 0.32 to 0.71 with highest agreement for facial palsy and lowest for knee jerk. Conclusion - The magnitude of the interobserver and intersign variation indicates that the interpretation of the neurological signs tested, without knowledge of the case history, should be done with some caution.

The Physical Inactivity Matrix: Lessons from the classification of physical inactivity interventions

Physical inactivity (PI), a leading modifiable cause of disease and injury, is endemic in industrialised nations. Although considerable research has been undertaken in this field, we lack a system to synthesise the research literature to inform policy and identify research needs. The aims of this study were to (1) develop a system to classify physical inactivity intervention studies, (2) examine the distribution of PI interventions published in the peer-reviewed health literature using the system, and (3) consider implications for future research. We developed the Physical Inactivity Matrix (PIM), with 12 intervention points, created by the intersection of two dimensions: the intervention target (individual, physical environment and social/cultural environment) and the activity focus (transport, work/school, leisure and consumer). A formal search of the health research literature identified 529 eligible studies and each was classified into one of the 12 cells of the PIM. Most studies were categorised as: individual-leisure (68%), individual-work/school (12%) or social/cultural environment-leisure (13%). Only 4% targeted the physical environment. The findings of this initial application of the PIM support the call for greater investment in policies, interventions and research that focus on the relationship between the environment and PI, and transportation in particular. There would be merit in establishing the inter-rater reliability of the PIM and applying it to a wider variety of studies, including those published in the transportation and urban planning literatures. The PIM could be a useful tool for monitoring trends in research directions and funding levels over time and across countries.     

Aptitude for physical exercise in a population of female hospital workers

Summary The aim of this study was to evaluate the level of physical capacity in a female hospital population of Paris and its suburbs. A total of 1505 women working in the selected departments filled in a questionnaire concerning their working conditions, life habits and health and also attended a medical examination. The effort test performed consisted in flexing the legs 20 times with the chest held straigt, in 40 s. The heart rates were measured for the first, the second and the third minutes of recovery (first 15 s multiplied by 4). The blood pressure was measured just after the heart rate, for the first and the third minute. Recovery indices have been constituted from the results. The respective weights of anthropometric and sociodemographic risk factors for recovery indices were studied in multiple logistic regression models. The classification enables us to consider about 25%–30% of our population as having a satisfactory physical capacity, about 26%–27% as having an acceptable capacit, and about 24%–27% as having a weak capacity. About 21% of the population presented an excessive pressure reaction and 44% a questionable pressure reaction. Our results concerning the level of physical capacity of the female nursing staff should be taken into account especially in the future planning of work loads and architectural choices, which must avoid excessive physical burdens in relation to this level. An improvement in the level of physical capacity could be envisaged as well.
