[Effect of huannao yicong capsule on senile mild cognitive impairment].
OBJECTIVE
To observe the effect of Huannao Yicong capsule (HYC) on senile mild cognitive impairment.


METHODS
Sixty-two patients were randomly divided into two groups, the 31 patients in the treated group were treated with HYC 3 capsules, 3 times daily, and the 31 in the control group with Hydergin 3 tablets, 3 times daily. Treatment for two successive months was a therapeutic course. The changes of cognitive effect index (CEI), integral of measuring scale (CCSE, FQA and MMSE), TCM Syndrome scoring, quality of life (QOL), cerebral arterial blood flow (CBF) and hemorrheologic parameters in the two groups were observed.


RESULTS
The total effective rate of treatment in improving cognition in the 30 patients of the treated group (with one case lost) was 83.33%, while that in the 29 patients of the control group (with two cases lost) was 48.28%, the difference between them was significant (u = 2.36, P < 0.05). Intent-to-treat analysis, namely, the case lost in the treated marked as ineffective and those in the control group as effective, showed the total effective rate in the two groups was 80.65% and 51.61% respectively, which also showed significant difference (u = 2.02, P < 0.05). In the treated group after treatment, the integrals of CCSE, FAQ and MMSE significantly increased (P < 0.05 or P < 0.01), the TCM Syndrome scoring decreased (P < 0.01), the scoring of QOL significantly improved, the mean BBF increased (P < 0.05 or P < 0.01), and the cerebral arterial resistance index improved significantly. All these improvements in the treated group were significantly higher than those in the control group respectively (P < 0.05). Besides, the hemorrheologic parameters in the treated group were improved, most of them were better than those in the control group (P < 0.05 or P < 0.01).


CONCLUSIONS
HYC has good therapeutic effect on senile mild cognitive impairment, it is safe without any adverse reaction.
