The NO content and the NOS activity were down in the PIH pregnant women placenta.This showed that the ghrelin regulated the VEGF and influenced the the NO down.And the placenta angiospasm,blood pressure highten, and the PIH were caused also by this. The ghrelin,VEGF,Flt-1,NO and NOS were detected by the SP-immunochemistry, RQ-PCR,cell culture in vitro,ASODN and nitrate reductase in the normal pregnancy,PIH placenta and the cultured HUVEC antisense blocking ghrelin in vitro.

结果证实：PIH孕妇胎盘组织中Ghrelin，VEGF、Flt-1蛋白和mRNA水平下降与正常孕妇比较有显著性差异p＜0.05提示在PIH发病过程中Ghrelin可能对VEGF，Flt-1蛋白和mRNA的表达具有下调作用，进而影响胎盘血管网的形成和发育；NO含量与NOS活力水平在PIH孕妇胎盘组织中下降，提示Ghrelin可能通过下调VEGF的表达进一步影响血管舒张因子NO水平下降，进而引起胎盘血管痉挛，血压升高，最终导致PIH的发生。

Methods The constriction induced by norepinephine (NE, 10-8-10-4 mol/ L) and diastole induced by acetylcholine (Ach, 10-8 -10-4 mol/ L) in thoracic aortic ring with angiosteosis induced by vitamin D3 plus nicotine in rats were recorded by BL-Newcentrary multichannel physiologic recorder.

维生素D3(VitD3)和尼古丁诱导大鼠血管钙化模型，通过BL-Newcentrary型多导生理记录仪，观察钙化大鼠离体胸主动脉环对去甲肾上腺素(norepinephine，NE)(10-8～10-4mol/L)和乙酰胆碱(acetylcholine，ACh)(10-8～10-4mol/L)引起的收缩和舒张反应。

Methods: Randomly divided 80 cases with chronic cardia failure into two groups, regular therapy group and bisoprolol group with 40 cases per group. Regular anticardiac failure therapy, including cardiac and diuretic therapy, was employed to patients in regular therapy group; while the combined therapy of regular therapy and bisoprolol was employed to patients in bisoprolol group. Compared the heart rate, left ventricular diastolic dimension, left ventricular systole dimension, left ventricular ejection fraction before and after therapy and efficiency of both groups.

80例慢性心力衰竭患者随机分为两组，常规治疗组40例，采用强心、利尿等抗心力衰竭常规治疗，富马酸比索洛尔治疗组40例，在常规抗心力衰竭治疗的基础上加用富马酸比索洛尔治疗，对两组临床疗效及治疗前、后心率、左心室舒张末内径、左心室收缩末内径及左心室射血分数的变化进行比较。

Skeletal muscle relaxation indexes can be regarded as applied objective in studying skeletal muscle fatigue and antifatigue.

Methods:Paticipants consisted of 32 simple VSD patients and 27 simple PDA patients excluded of any other diseases by physical examintation and electrocardiogram and x-ray. Patients were suggested echocardiography before and one week after the surgerys. Parameters such as Left ventricular ejection fraction、Fractional shortening、Left ventricular end-diastolic dimension、Left ventricular end-systolic dimension、Heart rate and Aortal velocity peak were measured.further more ,the Tei index which is originated from Pulse-wave Doppler and Tissue-Doppler Imaging were also calculated under ECG monitoring.

研究对象与方法：研究对象分别为排除其它心脏疾患的单纯动脉导管未闭患儿及单纯室间隔缺损患儿，手术治疗前后于心电监护下先行常规超声检查，获取心率、R-R间期、左室射血分数、主动脉峰值流速、左室收缩末期内径及左室舒张末期内径等值，并分别利用频谱多谱勒及组织多谱勒法测取患儿左室Tei指数(即PW-Tei及TDI-Tei)，多次测量并取其均值。
