先天性心脏病肺动脉高压患者心房钠尿肽及内皮素含量的临床观察

对67例临床和CT确诊新生儿颅内出血（ICH）的患儿进行了2～4年的随访观察，并定期进行体格发育检查和智能测定。结果显示，硬膜下出血的患儿预后最好,蛛网膜下腔出血者次之．脑室内出血预后最差。生后5分钟Apgar评分小于6分，且持续低分者神经系统预后差．就颅内出血部位、出血诱因对ICH远期预后影响的意义和机理进行了讨论．

Clinical studies of atrial natriuretic peptide and endothelin in patients with congenital heart disease with pulmonary hypertension

To observe the changes of artrial natriuretic peptide (ANP) and endothelin (ET) lev-els in patients with c0ngenital heart disease (CHD) and discuss their mechanism and clinical significance.Methods: The pulmonary pressure of the pulmonary hypertension (PH)group was higher than 2 kPa- Thepulmonary pressure of Non-PH group was n0rmal. Healthy children served as control group. Results: (1)Plasma ANP level of the PH group was apparently higher than that 0f the N0n-PH group and c0ntrolgroup. (2) Plasma ET levels in the peripheral vein, vena cava,right atrium, right ventricle, pulmonaryartery and left atrium of the PH group were particularly higher than that of the Non-PH group and c0ntr0lgroup, especially in the left atrium. C0nclusi0n: (l) CHD with PH induces the increase in cardiac v0lumeand pressure load, thus accelerates the release 0f ANP. It is actually a compensatory mechanism for the el-evation of endogenic ANP. (2) ET is a vasoconstrictor. ET owns the importance at PH pathogenesis andhas a certain clinical value in the diagn0sis 0f PH. (3) ET causes ANP releasing, then inhibits ET effectthrough negative feed. B0th of them are antag0nists each other.
