FMD of the brachial artery was examined by high-resolution ultrasonography technique and the inter-ventricular septum thickness, left ventricular posterior wall thicknessand left ventricular diastolic diameter were measured by echo-cardiography technique. The left ventricular mass and LVMI were calculated according to Devereux formulary. According to Framingham heart study, The hypertensive individuals were separated into two groups, left ventricular hypertrophy group and without left ventricular hypertrophy group.

利用高分辨超声技术测定肱动脉血流介导的舒张功能；超声心动图评价受试者的心脏结构功能，测量室间隔厚度(inter-ventricular septum thickness， IVST)、左室后壁厚度(left ventricular posterior wall thickness， LVPWT)及左室舒张末内径(left ventricular diastolic diameter， LVDD)，根据Devereux公式计算(left ventricular mass， LVM)按体表面积得出LVMI，并据Framingham心脏研究的标准将高血压组分为左室肥厚组(24例)与无左室肥厚组(31例)。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

Specifications have diameter: 50,55,65,70,75,80,90,100 mm and so on.

规格有内径为：50、55、65、70、75、80、90、100mm等。

The results show that the inner diametrical dimensions will decrease with increasing the feed、reduction rate and roller angle and increase with increasing the wall thickness.

结果表明：产品内径随进给比的增大而减小、随减薄率的增大而减小、随工作角的增大而减小、随壁厚的增大而增大。

In the current study it is difficult to be certain that the decreased aortic distensibility in aortic dissection were due to structural changes of the aortic wall, or simply reflected dilated aortic dimension and aortic valve regurgitation. Further study is necessary to elucidate the underlying mechanisms for this abnormalities.

本研究用无创的超声技术证明主动脉夹层之升主动脉扩张性明显降低，这对主动脉夹层病因学的进一步深入研究无疑具有重要意义；但其降低是由于血管本身结构异常所致还是继发于血管内径的扩张尚有待进一步深入研究。
