Clinical efficacy of Yangxueqingnao granule improve cerebral small vessel disease cognitive impairment / 中国基层医药

ABSTRACT

Objective To explore the effect of Yangxueqingnao granule in treatment of cerebral small vessel disease (SVD)patients with mild cognitive dysfunction (MCI).Methods 52 patients with SVD related MCI were selected.They were treated with Yangxueqingnao granule,each 4.0 g,3 times a day,3 months for a course of treat-ment.Montreal cognitive scale (MoCA),simple mental state scale (MMSE)and event related potential (P300)were detected before and after treatment,and the clinical effect was observed.Results After a course of treatment by Yan-gxueqingnao granule,the cognitive function and memory of 52 patients were improved to some extent.In addition to the attention of an MoCA meter to a foreign project[Visual spacebefore taking the medicine (2.92 ±0.26)points,after taking the medicine (3.25 ±0.66)points;Namedbefore taking the medicine (2.26 ±0.70)points,after taking the medicine(2.92 ±0.49)points;Languagebefore taking the medicine (1.47 ±0.70)points,after taking the medicine (2.17 ±0.98)points;Abstractionbefore taking the medicine (0.45 ±0.38)points,after taking the medicine (0.68 ±0.63)points;Delayed recallbefore taking the medicine (1.67 ±0.74)points,after taking the medicine (2.52 ±1.50)points;Directionalbefore taking the medicine (4.73 ±0.35 )points,after taking the medicine (5.52 ±0.57)points ]and total score[Before taking the medicine (18.75 ±0.66)points,after taking the medicine (19.12 ±1.45)points],the differences were statistically significant (the total scoret =7.56,P =0.000;Visual spacet =5.86,P =0.002;Namedt =5.42,P =0.000;Be carefult =1.23,P =0.121;Languaget =4.52,P =0.000;Abstractiont =2.65,P =0.001;Delayed memoryt =7.96,P =0.000).While the total score of MMSE scale [before taking the medicine (25.36 ±1.89)points,after taking the medicine (28.53 ±2.91 )points],memory [before taking the medicine (2.64 ±0.42)points,after taking the medicine (2.75 ±0.53)points]and recall [before taking the medicine (1.52 ±0.48)points,after taking the medicine (1.98 ±0.78)points ],the differences were statistically significant(the total scoret =2.78,Memoryt =1.95,Recallt =3.43,all P <0.05).P300 before and after treatment[before taking the medicine P300 latency of (389 ±21)ms,after taking the medicine P300 latency of (341 ±18)ms)],the difference was significant (t =12.514,P <0.001).Conclusion Yangxueqingnao granule had therapeutic effect in patients with SVD -MCI.
