Finding effective drugs to treat PAH is a problem needed to be resolved. The main purposes of this study therefore were:① To assess the significance of radionuclide ventriculography in the diagnosis of early cor pulmonale and cor pulmonale with right heart failure.② To assess the rule of hemodynamic changes in patients with cor pulmonale especially in those patients who had been in decompensatory phase.③ TO assess the correlation between mean pulmonary artery pressure and right ventricular ejection fraction in order to establish a equation for diagnosing PAH noninvasively.④ To assess the effects of nifedipine , captopril and combining nifedipine with captopril on the treatment of PAH.

本文对慢性肺心病、PAH的无创诊断和有效治疗两方面进行研究，其目的在于：①了解放射性核素检查对早期肺心病和肺心病合并右心衰竭诊断的意义；②了解肺心病病人尤其是失代偿期肺心病病人血流动力学的改变规律，了解平均肺动脉压与右室射血分数等的相关性，探索建立一个无创诊断PAH的回归方程，祈能提供今后临床使用；③观察硝苯吡啶、卡托普利和两药联用对PAP等血流动力学参数的影响。

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.

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。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
