Abstract:

Objective To explore the efficacy of modified Bu Pi Yi Xin decoction combined with N-butylphthalide (NBP) soft capsules in treating vascular dementia (VD) after cerebral infarction, and its influences on cognitive function, serum histone deacetylase 6 (HDAC6) and neuregulin 1 (NRG1) levels. Methods One hundred patients with VD after cerebral infarction were included and randomly divided into the NBP group and the combined group according to the random number table method, with 50 cases in each group. In the NBP group, NBP soft capsules were used for treatment, while in the combined group, on the basis of the NBP group, modified Bu Pi Yi Xin decoction was given. The differences in the total scores of traditional Chinese medicine (TCM) syndromes, cognitive function [Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores], degree of dementia [Clinical Dementia Rating (CDR) score and modified Hasegawa Dementia Scale (HDS-R) score], hemorheology [high/low shear whole blood viscosity and plasma viscosity] and serum-related factors [HDAC6, NRG1 and brain-derived neurotrophic factor (BDNF)] were compared before and after treatment between the two groups. Results After treatment, the total effective rate was higher in the combined group than that of the NBP group (P<0.05). After treatment, the total score of TCM syndromes and CDR score were lower in the combined group than those in the NBP group (P<0.05), and MMSE score, MoCA score and HDS-R score were higher in the combined group than those in the NBP group (P<0.05). After treatment, the high/low shear viscosity of whole blood, plasma viscosity and serum levesl of HDAC6 were lower in the combined group than those in the NBP group (P<0.05), while serum levels of BDNF and NRG1 were higher in the combined group than those in the NBP group (P<0.05). Conclusion The modified Bu Pi Yi Xin decoction combined with NBP soft capsules have a significant therapeutic effect on VD patients after cerebral infarction, and it can alleviate the severity of dementia, improve cognitive function, reduce blood viscosity and increase serum levels of HDAC6 and NRG1.
