舒张

Endothelium-independent relaxations were identical in all groups.

所有实验组小鼠非内皮依赖的血管舒张反应相同。

AQ technique may be used as a method to quantify the left ventricular diastolic function in patients with HCM.

AQ技术为定量评价HCM患者的左室舒张功能提供了新的途径。

This leads to subtle changes in the autonomic nervous system, which controls the contraction and relaxation of these vessels.

这使得控制血管收缩和舒张的自主神经系统发生了微妙的变化。

Objective To investigate the serum levels of expression of MMP-2 and MMP-9 in SHF, CHF and control groups respectively for the purpose of approaching the internal relationship between MMP-2, MMP-9 and CHF. Through the way, we could further study whether MMPs can be regarded as a new target to evaluate the progressing as well as the treatment and prognosis of CHF.

目的 检测收缩性心衰及舒张性心衰患者和正常对照组血清中血清基质金属蛋白酶2，9的含量，探讨两种类型心衰与MMP-2，MMP-9表达的内在关系，从而进一步探讨MMP-2，MMP-9是否可作为心衰病情进展和评价心衰治疗效果及预后的新指标。

METHODS:DHF patients and the systolic heart failurepatients were selected by questionnaires, medical checkup and ultrasonocardiograph, and they were divided into DHF group, SHF group and normal

通过填写心力衰竭调查表、体格检查、生化检查、超声心动图检查，并结合其他检查结果，将参加实验人群分为：舒张性心力衰竭组、收缩性心力衰竭组，心功能正常组。

Result In the experimental 11 groups, heart rates of young Hailan chickens were close to that of others, but their values were higher than that of chickens in old days. Breathing frequency test showed 140, 280 and 420 days old chicken were significantly different with others. Contraction and diastolic pressures of 6 groups were gradually increased with growth of days, that of 280 and 420 days chicken were significant different.

结果］在11组中，小年龄段海兰鸡心率与其他鸡心率接近，但高于大年龄段的心率值；呼吸频率测定结果140、280和420日龄组与其他组差异极显著；6组海兰鸡收缩压与舒张压都是随着年龄的增长而升高，28与420日龄组差异极显著。
