不稳定心绞痛患者的溶栓治疗

将64例不稳定心绞痛（UAP）患者随机分成2组，一组用常规抗心绞痛药物治疗（对照组），一组加用尿激酶做溶栓治疗（溶栓组）。两组疗效比较显示：溶栓组治疗总有效率明显高于对照组（P〈0．05）。其减少心绞痛发作次数，减低心绞痛分级，改善ECG方面均优于对照组（P＜0．05）。而且血浆脂质过氧化物（LPO）明显减低，红细胞超氧化物歧化酶（SOD）活性明显升高（P〈0．05）。提示UAP患者应行尿激酶溶血栓治疗。但两组演变为急性心肌梗塞的百分率及死亡率无明显区别。

EFFECTS OF THROMBOLYSIS WITH ULTRASOUND ON THE STRUCTURE OF ERYTHROCYTE AND ITS SAFETY THRESHOLD

The study was to investigate thrombolysis in vitro with ultrasound, and to discuss effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold under different ultrasound intensity and exposure time. The structure of erythrocyte in thrombus was evaluated under light microscope. The relationship between the structure of erythrocyte in thrombus and ultrasound intensity and exposure time was obtained. The results showed that ultrasound eliminated the thrombus. According to the change of the structure of erythrocyte in thrombus and ultrasound intensity and exposure time, the effects of thrombolysis with ultrasound could be divided into three kinds of areas： the A, B, C area. The area A was the safe area, the area B was the relatively safe area, and the area C was the irreversible damage area. The study suggested that ultrasound intensity and exposure time had significant impact on the structure of erythrocyte. Stronger ultrasound intensity or longer exposure time could cause erythrocytes irreversible damage. It could accelerate thrombolysis and shorten the exposure time that the ultrasound intensity was little bit increased. The study of effects of thrombolysis with ultrasound on the structure of erythrocyte and its safety threshold were important for practical applications.
