P波时限、P波离散度对特发性心房颤动的预测价值初探

Objective:To assess the sensitivity and the specifity of predicting idiopathic AF with P wave dura-tion and P wave dispersion. Methods: The maximum P wave duration and P wave dispersion in 36 patients with idio-pathic AF were measured and compared with those of sex-and age-matched healthy subjects. Results:The maxi-mum P wave duration and P wave dispersion were higher in patients with idiopathic Af than in control group. Themaximum P wave duration >110ms or P wave dispersion >40ms was used to differentiate patients from healthy     

劳动姿势对流量－容积曲线的影响─—波速学说的进一步验证

用“点值法”对健康工人４７３例［轻体力劳动工人（简称轻工）２４８例，重体力劳动工人（简称重工）２２５例］。作了流量一容积曲线和常规通气功能检查。结果表明：重工男女在４０岁以后其高肺容积流量下降，３０岁以后低肺容积流量上升，而且这些改变有随年龄增长而更加明显的倾向；轻工仅有个别年龄组的低肺容积流量上升。对７名健康坐位工作者模拟劳动的前倾姿势作多次通气功能检查，亦有明显高肺容积流量下降和低肺容积流量上升的现象，这一事实提示波速学说亦可应用于颈和躯干前倾进行重体力劳动工人的通气行为。     

Experimental and theoretical models of flow during forced expiration: pressure and pressure history dependence of flow rate

Flow characteristics have been studied in elastic mono- and bialveolar lung models made from tubes and balloons in series. Flow rate variation is explained on the basis of two successive limiting factors governed by the mutual interaction of tube mechanical properties and flow characteristics, i.e. wave-speed and viscous limitations induced by the tube collapse. A numerical model of flow in an elastic monoalveolar structure has been developed. It is generally admitted that a remarkable feature of forced expiration is that the flow rate is ‘effort independent’ for approximately the lower 80 per cent of vital capacity. The present results, which describe a continuous process, suggest that the flow rate depends mostly on the external pressure and pressure history. between the 15th August 1987 and the 31st August 1988, and at other periods to him at INSERM U. 296, Faculté de Médecine, 8 av Gl Sarrail, 94010 Creteil Cedex, France.     

Analyzing Event-Related Potentials: The Utility of High and Low Pass Filtering in Improving the Relationship Between Various Amplitude Measures and Principal Components Analysis Factor Scores

The present investigation sought to determine whether the relationship between event-related potential (ERP) principal components analysis (PCA) factor scores and analogous waveform amplitude measures could be improved by high- and low-pass filtering the waveforms at a suitable cutoff value. Visual oddball ERPs were submitted to a varimax-rotated PCA performed on the variance/covariance matrix. Principal components corresponding to P300 and Slow Wave were obtained. In keeping with the fact that the variance/covariance PCA analyzes sources of variance around the grand mean waveform, the grand mean waveform was subtracted from each of the original waveforms, and baseline-referenced amplitude measurements were then made of P300 and Slow Wave. P300 was measured both as the maximum positive peak between 275 and 425 ms, and as the average amplitude during that interval. Slow Wave was measured as the average amplitude during the interval 400–700 ms. The P300 measurements were then repeated after high-pass filtering the difference waveforms at 2 Hz. Slow Wave measurements were repeated after low-pass filtering at 2 Hz. The value of 2 Hz was chosen as giving a reasonable cutoff based upon estimates of the wavelengths of the two components derived from inspection of their respective factor loading vectors. The correlation between factor scores and amplitude measurements was .94 for unfiltered Slow Wave and actually declined slightly but significantly to .91 when the waveforms were low-pass filtered. It would appear that Slow Wave factor scores emerging from a PCA can be fairly well approximated by a time-band measurement algorithm, and that this approximation is not improved by low-pass filtering. For both filtered and unfiltered measurements of P300, the amplitude/factor score correlation was significantly higher for the time-band method than for the peak method. Further, high-pass filtering at 2 Hz improved the time-band/factor score correlation significantly from .62 to .75. This improvement is probably because the unfiltered measurements were tapping sources of variance due both to the higher frequency P300 component as well as a simultaneously active, lower frequency Slow Wave component. Theoretical implications of these findings are discussed.     

用声轨迹标定大肠经体表线路研究的新进展

经络输声疗法对原发性痛经的经络调整作用

本文以月经相关经脉的声传导的变化为观察指标，通过经络输声疗法对８２例原发性痛经治疗效果的观察，以验证经络输声疗法对经络的调整作用。将８２例原发性痛经随机分为３组，分别用３个频率治疗，进行对比分析。临床结果表明：经３个月经周期的治疗，痛经症状积分明显下降；月经血色、血量、血块趋于正常；总有效率为９６．４３％；对虚实证均有效，但其输声频率的选择有差异。说明经络输声疗法对经络有疏通、调节作用。实验结果表明：经络输声能改变原发性痛经相关经脉的声传导状态，治疗后经络导声恢复正常，证实了经络输声对经络的调整作用。从客观上显示了有关经络的病理及愈复变化。此项研究国内外尚无报道。
