Objective: To observe the therapeutic effect of treatment at selected time on acute ischemic apoplexy and changes of hemorheologic indexes. Methods: 58 cases of acute ischemic apoplexy were randomly divided into a group of treatment at selected time （observation group） and a group of treatment at any time （control group）. The observation group were treated by moxibustion at Zusanli （ST 36）and Shenque （CV 8）at Chen hours （7-9 o’clock am）each day

20min each session

in combination with Chinese drugs Tongluo Decoction

one dose daily

oral administration

once at Chen hours. The control group were treated by the same methods at any hours except Chen hours. The therapeutic effects were assessed after 3 treatment courses. Hemorheologic indexes were determined before and after treatment in both groups. Results: The cured rate and the markedly effective rate in the observation group were better than those in the control group （P<0. 01）. The hemorheologic indexes in the two groups after treatment had some improvements with statistically significant differences in the observation group （P<0. 05 or P<0. 01）

and the observation group being superior to the control group after treatment （P<0. 01）. Conclusion: Selection of suitable therapeutic time conforms to view point of modern time therapeutics and can increase therapeutic effect.
