Clinical Efficacy of Tongqiao Huoxuetang in Treating Blood Stasis Type Vascular Cognitive Impairment
This study aims to observe the clinical efficacy of Tongqiao Huoxuetang in treating blood stasis resistance type vascular cognitive impairment
and explore its mechanism of action.
Method:
2
A total of 60 patients who met the inclusion standards and were diagnosed as blood stasis resistance type vascular cognitive impairment were randomly divided into treatment group and control group
30 patients in each group. Donepezil hydrochloride was administered orally in control group based on internal medicine treatment at an initial dose of 5 mg/day
changed to 10 mg/day 4 weeks later. Patients in treatment group additionally received Tongqiao Huoxuetang based on donepezil hydrochloride. Both groups were treated for 3 months. Changes of symptoms were assessed by syndrome scores; cognitive function was assessed by the mini-mental scale (MMSE); daily living ability was assessed by the activity of daily living scale (ADL)
and changes of local blood perfusion (CBF value) was assessed by brain magnetic resonance perfusion imaging arterial spin labeling (MRI-ASL). Changes of homocysteine levels in plasma were measured by using an automated biochemical analyzer.
Result:
2
① The values of traditional Chinese medicine(TCM) syndrome scores (SDSVD) were significantly improved in both groups after treatment
and the improvement was more obvious than that of control group (
P
<
0.05). ② The cognitive ability and daily living ability of the patients were significantly improved; the MMSE scores and ADL scores were improved significantly in both groups after treatment (
P
<
0.01)
and improvement in treatment group was more obvious than that of control group (
P
<
0.05). ③The CBF value in treatment group was significantly higher after treatment (
P
<
0.05)
and also higher than that in control group (
P
<
0.01). ④ Homocysteine level in plasma of treatment group was significantly lower than that of control group (
P
<
0.05).
Conclusion:
2
The combination of Tongqiao Huoxuetang combined with donepezil hydrochloride can effectively improve the cognitive ability and daily living ability of the patients with vascular dementia
improve the cerebral blood flow perfusion and decrease the level of homocysteine
