舒张前期

It was suggested that aging did not only influence diastolic filling period, but also influence STI. 3. With increasing age, whether at rest or during exercice, fractional shortening of minor semiaxis, mean velocity of circumferential fiber shortening, cardiac index and ejection fraction did not change, but immediately post pacing, PEP prolonged and PEP/ LVET increased in elderly group and did not change in young group. It was suggested that STI was sensitivity in detecting systolic function of LV. 4. There was a good correlation between aging and decreased compliance and diastolic function of left ventricle which was manifested by a reduction of early diastolic peak folw velocity, time-velocity integral of early diastole, 1/3 filling fraction (1/3FF)(r=-0.958,-0.875 and -0.937, P＜0.01～0.001) and a significant compansatory increase in peak flow velocity of atrial contraction, time-velocity integral of atrial contraction, the ratio between APFV and EPFV and the ratio of ATVI and Total TVI (r=0.958, 0.956, 0.966 and 0.986, P＜0.001) and the prolongation of Dec T and RFP with increasing age. It was particularly true for the subgroups above the age of 50 years.

静息状态下收缩时间间期与年龄无相关性，负荷后即刻，老年组射血前期延长(P＜0.05)，射血前期与射血期比值加大(P＜0.05)，青年组无变化，提示年龄因素亦影响STI，但由于静息状态下得到代偿，STI变化往往表现不明显。3、静息及负荷状态左室短轴缩短率、平均周径缩短率、心指数及射血分数均不随年龄增长而变化，而负荷后即刻老年组PEF延长，PEP/LVET加大，提示STI是检测左室收缩功能的敏感指标。4、随年龄增长，心房收缩期充盈峰值流速、流速积分、充盈分数及心房收缩期与舒张早期充盈峰值流速之比值显著增高(r＝0.958、0.956、0.986及0.966，P均＜0.001)，舒张早期充盈峰值流速及流速积分、1/3充盈分数(1/3FF)下降(r＝-0.958、-0.875及-0.937，P＜0.01～0.001)。

Prehypertensive subjects versus normotensive subjects had significantly higher body mass index and subscapular skinfold, systolic and diastolic blood pressures, and triglycerides beginning in childhood; higher glucose in adolescence; and higher low-density lipoprotein cholesterol, fasting insulin, and insulin resistance index in adulthood. Hypertensive subjects versus normotensive subjects had higher adiposity measures, SBP and DBP, glucose, and triglycerides beginning in childhood; higher insulin and insulin resistant index in childhood and adulthood; and lower high-density lipoprotein, cholesterol in adulthood.

与正常血压者相比，高血压前期者其幼年期基础体重指数、肩胛下皮肤皱褶厚度、收缩压和舒张压、甘油三脂等指标更高；在青春期血糖水平更高；在成年期低密度脂蛋白胆固醇、空腹胰岛素、胰岛素抵抗指数更高；与正常血压者相比，高血压者在幼年时基础水平的肥胖积分、SBP 和DBP、血糖、甘油三脂等更高；在幼年期和成年期胰岛素和胰岛素抵抗指数水平均更高；在成年期高密度脂蛋白胆固醇水平更低。

Methods 20 patients with complete left bundle branch block and 20 normal subjects were studied.

方法对20例完全性左束支传导阻滞患者和20例正常人解剖M型在心室波群区观察室间隔与左室后壁运动；运用频谱多普勒成像技术测量左、右心室射血前期时间（LVPET、RVPET），计算两者之差PETd；采用定量组织速度成像技术测量右室侧壁基底段和左室各壁基底段达收缩期峰值速度时限和达舒张早期峰值速度的时限。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
