[Effects of dioscorea modified pill on cognitive impairment of patients with VCIND: an preliminary study of proton magnetic resonance spectroscopy].

OBJECTIVE: To explore the therapeutic effect evaluation of proton magnetic resonance spectroscopy ((1)H-MRS) in patients with vascular cognitive impairment no dementia (VCIND) with dioscorea modified pill. METHODS: A total of 100 patients with VCIND were randomly assigned into the dioscorea modified pill group (n = 50) and the aricept group (n = 50). And 50 healthy volunteers were recruited as normal group. Each patient was examined with (1)H-MRS and scored with mini-mental state examination (MMSE) and clinical dementia rating (CDR) scale pre- and post-treatment. RESULTS: After therapy, the NAA/Cr ratios and the itemized scores of cognitive scale compared with that of pre-therapy had significantly difference (P < 0.05) in the dioscorea modified pill group (MMSE (26.5 ± 2.0), CDR(0.14 ± 0.23))vs(MMSE(25.1 ± 2.3), CDR(0.5)). But no difference existed in the aricept group (P > 0.05). CONCLUSION: (1)H-MRS may objectively reflect cognitive dysfunction in VCIND patients. And it has important values in the therapeutic effect evaluation of VCIND with dioscorea modified pill.

[Clinical research of early intervention of modified shuyu pill in vascular cognitive impairment no dementia].

OBJECTIVE: To observe early intervention effects of Modified Shuyu Pill (MSP) on vascular cognitive impairment no dementia (VCIND). METHODS: Totally 100 patients VCIND were randomly assigned to the treatment group (43 cases) and the control group (33 cases). On the basis of the treatment targeting risk factors of blood vessels, patients in the treatment group were treated by MSP, while those in the control group were treated by donepezil hydrochloride. The therapeutic course was 16 weeks. The neuropsychological scales [mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA) score] and Chinese medicine dementia syndromes scales were observed before and after treatment. RESULTS: The MMSE and MOCA score of the two groups increased when compared with the same group before treatment (P < 0.01). But there was no statistical difference in MMSE or MOCA score after treatment between the two groups (P > 0.05). The Chinese medicine dementia syndromes scales significantly decreased in the treatment group when compared with before treatment (P < 0.01). But there was no statistical difference in Chinese medicine dementia syndromes scales in the control group between before and after treatment (P > 0.05). There was statistical difference in Chinese medicine dementia syndromes scales after treatment between the two groups (P < 0.01). CONCLUSION: MSP could effectively intervene the progress of VCIND.
