Abstract］ Objective To assess the endothelium-dependent relaxation in patients with essential hypertension or hypertension smokers by color Doppler flow imaging.Methods With intermittent ultrasound imaging and power Doppler imaging,we measured endothelium-dependent relaxing function in 72 subjects 24 of whom with essential hypertension,24 of whom with both hypertension and smokingand the others as normal control.We measured the diameter of the superficial femoral and brachial arteries at rest,during reactive hyperaemia,re-test and after sublingual glyceryl trinitrate for evaluating the endothelium-independent dilatation in subjects.The level of plasma NO,ET,PGI2,and TXB2 were determined.

摘要］ 目的探讨原发性高血压及高血压合并吸烟患者血管内皮依赖性舒张功能的改变方法采用彩色普勒高频超声的间歇成像和能量多普勒成像，对24例原发性高血压患者、24例高血压合并吸烟患者及24例正常血压无吸烟史者的血管内皮依赖性舒张功能，包括静息时血管内径、增加流量引起的血管舒张、硝酸甘油引起的血管舒张等，以及对血浆氧化氮、内皮素、血栓素B2（TXB2）和列腺环素（PGI2）等血管活性物质进行检测并比较分析。

Sand hair goat breeding has a long history, is a long-term specific local ecological environment, natural selection and artificial selection under the influence of the formation of the joint. In l951, as local sand wool fur products on display in Beijing, has aroused attention of the relevant experts and scholars and, through investigation and research in the areas, known as the Zhongwei goat fur. In the early 50 international markets in Europe, some experts have caused surprise and appreciation.

沙毛山羊养殖已有悠久的历史，是长期在当地特定的生态环境中，自然选择和人工选择共同影响下形成的。l951年沙毛裘皮作为地方特产在北京展出时，引起了有关专家学者的注视，并通过在产区调查研究，定名为中卫裘皮山羊。50年代初期在欧洲国际市场出现，也曾引起一些专家的惊奇与赞赏。

In recent years, lightning stroke is one of the important causes of the accidents that occur on transmission lines. With the increase of voltage grade of transmission line, the proportion of outages because of shielding failure also increases. Therefore, exactly evaluating lightning-withstanding level and shielding failure flashover rate of transmission line, is especially important for system service and stable operation.
