Heart rate fluctuations in diabetic patients with cardiac vagal dysfunction: a spectral analysis

The autonomic nervous control of cardiac function during active orthostatic load has been studied by measuring the power spectrum of heart rate fluctuations in 16 insulin-dependent diabetic patients and 14 age-matched control subjects. The patients were subdivided into two groups: 8 with normal respiratory sinus dysrhythmia (RSA+) and 8 with reduced respiratory sinus dysrhythmia (RSA-). In RSA- patients the total power (0.01-0.50 Hz) was significantly reduced compared with control subjects (4.7 versus 15.5 min-2, 2p less than 0.05) and the pattern of heart rate fluctuations was characterized by a relative increase in the low-frequency component (0.01-0.05 Hz) as compared with RSA+ patients and control subjects (45% versus 24% and 27%, both 2p less than 0.01). There was also a significant reduction in the high-frequency component (0.15-0.50 Hz) as compared with RSA+ patients and control subjects (17% versus 36% and 33%, both 2p less than 0.05). During standing, a significant increase in total power was found only in control subjects (2p less than 0.01) and the difference between control subjects, and RSA+ and RSA- patients reached significance (32.2 versus 15.1 and 12.7 min-2, 2p less than 0.02 and 2p less than 0.01). The pattern of heart rate fluctuations in RSA- patients showed no significant change on standing. These results suggest that the reduced overall heart rate variability in diabetic patients with cardiac autonomic neuropathy is associated with a typical heart rate fluctuation pattern.     

心脏病患者血清七种元素含量与血压及生化指标的关系

我们检测了心脏病患者血清微量元素Ｚｎ、Ｃｕ、Ｆｅ和常量元素Ｋ、Ｎａ、Ｃａ、Ｍｇ的含量，并与血压及生化指标作相关分析。结果发现心脏病患者Ｋ和Ｃａ／Ｍｇ显著低于对照组，而Ｎａ、Ｍｇ、Ｚｎ、Ｆｅ和Ｎａ／Ｋ、Ｚｎ／Ｃｕ则显著高于对照组。Ｋ、Ｃａ／Ｍｇ与血压呈负相关，而Ｎａ、Ｚｎ、Ｆｅ、Ｚｎ／Ｃｕ和Ｎａ／Ｋ与血压呈正相关；Ｆｅ与红细胞压积（Ｈｃｔ）呈正相关；Ｚｎ／Ｃｕ与Ｈｃｔ、甘油三酯、极低密度脂蛋白均呈正相关，而与高密度脂蛋白呈负相关。     

5名电离辐射事故患者外周血T细胞T细胞抗原受体、T细胞分化抗原决定簇－3效应的研究

文中报道了５名事故性急性骨髓型放射病患者照后２．５和３．５年外周血Ｔ淋巴细胞Ｔ细胞受体（ＴＣＲ）基因，ＴＣＲ、Ｔ细胞分化抗原决定簇－３（ＣＤ_３）表达与ＴＣＲ／ＣＤ_３复合物功能的辐射效应．发现５名患者于照后２．５年，２名（５．２Ｇｙ和２．４Ｇｙ，５５岁）于照后３．５年外周血Ｔ细胞应答抗ＣＤ３单抗刺激而增殖的能力尚未完全恢复；经同时用ＩＬ－２和抗ＣＤ_３单抗刺激，增殖能力比单用抗ＣＤ_３单抗刺激有所增强；后２名的外周血ＴＣＲ、ＣＤ_３阳性细胞百分率一直低于正常对照和其他患者；并见一患者出现ＤＮＡ重排杂交带型．本文并从ＴＣＲ／ＣＤ_３在介导Ｔ细胞抗原刺激反应中的作用，电离辐射对ＴＣＲ／ＣＤ_３复合物的影响，后果和意义等方面进行了讨论．

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.

动态MRI对臂丛根性损伤和颈髓损伤的鉴别诊断意义

目的探讨动态MRI诊断臂丛神经根性损伤的影像学表现及其诊断价值，以及在与颈髓损伤的鉴别诊断中的临床意义。方法对8例臂丛神经根性损伤患者行动态MRI检查，结合CT薄层扫描和肌电图随访；所有8例患者均手术证实为臂丛根性损伤。结果本组患者在伤后早期1～2d内均无位于椎间孔及椎间孔外的创伤性脊膜囊肿、神经根断裂等支持臂丛根性损伤的MRI异常表现；4例患者有颈椎骨折或颈髓损伤的MRI表现。伤后7～15d（平均10d）后，再次行颈椎MRI检查，出现典型的MRI臂丛根性损伤表现：椎间孔及椎孔外臂丛神经走行处T2WI高信号的创伤性脊膜囊肿、脊髓移位和神经根缺失及走行异常等。结论动态MRI检查对臂丛根性神经损伤具有损伤节段定位准确、椎管外部分同样能够显示、无创、操作简单、准确性高等特点；其短期内特征性的动态变化易于诊断臂丛根性损伤，同时又能与颈髓损伤相鉴别。
