Objective: To observe the curative effect of extract of ginkgo biloba injection combined with donepezil in treating vascular dementia (VD) and to explore its effect on anti-oxidation activity
vascular endothelial function and cerebral hemodynamics. Method: Seventy patients with VD were randomly divided into control group and observation group of 35 patients each by random number table. Patients in control group took 10 mg donepezil hydrochloride tablets orally daily for 3 months. Based on the treatment of control group
patients in observation group added extract of ginkgo biloba injection intravenous drip
20 mL/time
twice daily for six 10 days courses of treatment separated by 5 days without treatment. Scores of activities of daily living (ADL)
digital simultaneous voice and data (DSVD) and mini-mental state examination were graded before and after treatment. Levels of serous endothelin (ET)
nitric oxide (NO)
superoxide dismutase (SOD) and malonaldehyde (MDA) were detected. Average blood velocities of arteria cerebri anterior (ACA) and middle cerebral artery (MCA) pulsatility index were detected by transcranial doppler. Result: The total effective rate of cognitive ability in observation group was 77.14%
which is superior to that in control group 51.43%(P<0.05). The total effective rate of activity of daily living in observation group was 80%
which is superior to that in control group 57.14%(P<0.05). Grades of ADL and MMSE in observation group were higher
and grade of DSVD was lower than those in control group after treatment (P<0.01). Levels of NO
ET and MDA in observation group were lower than those in control group
level of SOD was higher than that in control group (P<0.01). Average blood velocities of ACA and MCA in observation group were higher than those in control group (P<0.01). ACA and MCA pulsatility index in both groups had a decreasing trend
but there was no statistically significancent difference. Conclusion: Extract of ginkgo biloba injection combined with donepezil can improve the ability of living and understanding of patients with VD. Its mechanism of action may be relevant to ameliorating endothelial function
