舒张

The aim of the present study was to establish a non invasive technique of transdermal drug iontophoresis to assess cutaneous endothelial function in hypertensive patients.

目的 内皮细胞功能是目前研究的热点，本研究用离子电渗透法比较了高血压患者和正常血压者内皮细胞功能和血管舒张功能。

The isolated working heart model was set up, high-performance liquid chromatography were used to measure myocardial adenosine triphosphate,total adenine nucleotides, while left ventricular end-diastolic pressure,left ventricular developed pressure, and rate of change of left ventricular pressure were determined before and after preservation.

对照组用St Thomas停搏液停搏并保存大鼠心脏6小时；实验组在St Thomas液中加入前列腺素E1(5 μg/L)停搏并冷保存6小时，利用离体鼠心非循环式Langendorff灌流功能测定模型，测定左心室舒张期末压、左心室发展压和左心室压力变化率，并检测心肌细胞线粒体三磷酸腺苷、腺嘌呤核苷酸总量。

Meanwhile,concentrations of KP and ANP in atrium and aorta of the rats were observed as well.

KP不仅具有和ANP一样的利尿、舒张血管、抑制肾素-血管紧张素系统的作用，还具有抑制心肌Na+-K+-ATP酶的作用〔2〕。

Objective:To find a new quantitative method to determine the left atrial mean pressureand left ventricular diastolic function.

目的：探讨定量评估左房压力和左室舒张功能的新途径。

This was associated with increased end-diastolic pressures during handgrip exercise and with decreased stroke volume and a leftward shift of pressure-volume loops during atrial pacing.

这与在握力试验中增加舒张末期压力和在心房起搏时减少猝发容量和左转向压力容积环路相关联。

METHODS: Both diastolic and systolic blood pressures repeated measures data, collected from 120 drug abusers after taking two kinds of medicine (Drug A: Xiaoyinfuzheng, Drug B: Kelening), were analyzed by multivariate random coefficients model. The fixed effect parameters matrix x of model coefficients were estimated by using least squares estimation method, the effects between treatment groups were compared and the variancecovariance matrices of random effect were also estimated.

对两种药物（A药：消瘾扶正胶囊，B药：可乐宁）治疗120例患者后的舒张压和收缩压重复观测数据进行多变量随机系数模型分析，对模型系数的固定效应参数矩阵ξ作最小二乘估计并进行组间比较，同时估计随机效应的方差协方差矩阵，分析方法用SAS/IML软件编程得以实现。

无症状的轻度高血压患者可出现冠脉储备降低和舒张功能异常。

Materials and Methods:141cases of senile cervical spondylosis were measured at vertebral artery with 5.0-7.5 MHz probe of Ultrasonic Doppler,to find morphological changes and Maximum,Minium,Time Average Maximum,Diameter At the same time,the controlled analysis were performed on 200 cases of the healthy aged.

材料和方法：应用超声多普勒诊断仪，探头5.0～7.5MHz，检测141例老年颈椎病患者的椎动脉，观察形态与结构变化，获取收缩期峰值流速、舒张末期流速、时间平均流速、内径，并与200例健康老人进行对照分析。
