Abstract:Objective: To observe the therapeutic effect of Xinnaoxin capsules in patients with chronic cerebral circulatory insufficiency. Method: Patients with chronic cerebral circulatory insufficiency were divided randomly into two groups: a Xinnaoxin capsules group (n=60, treated by Xinnaoxin capsules for four 4 weeks), a control group (n=58, treated by Nimodiping for four weeks). The transcranial doppler (TCD) was used to determined mean velocity (Vm) and auto-viscometer measured hemorheological indices before and after being treated. Result: After 4 weeks treatment, the hemorheological indices and mean velocity were obviously improve in Xinnaoxin capsules group (P<0.05), there is significant difference between the effective rate of two groups (88.3%, 70.7%). Conclusion: Our study suggest that Xinnaoxin capsules have therapeutic function on chronic cerebral circulatory insufficiency.
