Trephine craniotomy in neurosurgery]

For three years, we have performed craniotomy with a 5 cm diameter trephine through a linear incision. 53 craniotomies were done in 49 patients. This simple and time-saving method produced little bleeding and slight injury to the brain. The technique allowed the surgeon to spend most of his time at the management of lesion. Healing of wound was rapid and brain edema was minimal.     

Ketanserin降低清醒自发性高血压大鼠血压波动性的机理初探

应用计算机化清醒大鼠血流动力学测定技术，观察５－ＨＴ２受体阻滞剂Ｒｉｔａｎｓｅｒｉｎ（Ｒｉｔ）和α１受体阻滞剂哌唑嗪对清醒自发性高血压大鼠（ＳＨＲ）的血压、血压波动性（ＢＰＶ）和动脉压力感受性反射血压控制部分（ＡＢＲ－ＢＰ）的效应，旨在初步探讨兼具５－ＨＴ２受体和α１受体阻滞作用地新型抗高血压药Ｋｅｔａｎｓｅｒｉｎ降低ＢＰＶ的机制。结果表明：Ｒｉｔ对ＳＨＲ无降压作用，但侧脑室给药明显提高ＡＢＲ－Ｂ     

Does beta adrenergic blockade influence the prognostic implications of post-myocardial infarction exercise testing?

The influence of beta blockade on the ability of ST depression, during pre-discharge exercise testing, to predict coronary anatomy and subsequent complications was studied in 300 consecutive post-infarct patients, 125 of whom underwent cardiac catheterisation. At the time of exercise 62 patients were taking a beta blocker. The exercise test had a higher sensitivity in predicting multivessel disease in patients who were not taking beta blockers than in patients who were (95% v 76%). beta Blockade did not, however, influence the ability of the test to identify patients at risk of subsequent cardiac events (sensitivity 84% and 85% respectively). These results suggest that it is not necessary to stop treatment with beta blockers before predischarge exercise testing of patients who have had an acute myocardial infarction.     

尿毒症患者的血小板聚集功能变化及血液透析的影响

本文应用 ADP、肾上腺素及复合诱聚剂对30例慢性肾功能不全(尿毒症期)病人的血小板聚集功能进行了检测,其中5例在血液透析前后分别测定。结果表明尿毒症患者血小板聚集功能障碍,血液透析有助于改善血小板功能。通过相关性检验,发现尿毒症病人的血小板聚集率与血肌酐值呈负相关性,其意义尚需进一步探讨。
