本文对２８例脑梗塞病人和对照组２０例的血小板聚集、粘附和红细胞滤过指数进行了２４小时周期变化的观察，并同缺血性中风昼夜发病时间进行了对比研究，发现两组指标表现出以凌晨４时为高峰的昼夜２４小时周期节律变化、同步变化和相关性，脑梗塞组发病时间的昼夜分布差异与上述流变学指标的高峰值相吻合，这时临床预防和治疗时间性有重要意义。 In this paper, twenty-eight patients with cerebral infarction and control group, 20 cases of platelet aggregation, adhesion and erythrocyte filtration index were observed 24-hour cycle, and ischemic stroke daytime onset time were compared and found two groups of indicators Showed that the circadian rhythm, synchronicity and relativity of the circadian rhythm at 4 o’clock peaked at 4 o’clock in the morning and night. The diurnal distribution of the onset time of the cerebral infarction group coincided with the peak value of the above rheological index, and the time of clinical prevention and treatment Sex is important.
