To explore the rules of acupoints selection based on syndrome differentiation and acupuncture treatment of vascular dementia.

The acupuncture treatment of vascular dementia based on syndrome differentiation was searched from CNKI, Wanfang and VIP databases. The search period was from Januare 1st of 2012 to December 31st of 2022.The data was organized using Microsoft Excel 2016, managed using SPSS Modeler 18.0 and SPSS 26.0 to analyze the acupoint selection rule based on syndrome differentiation and acupuncture treatment.

(1)Forty-eight literatures were finally included concerning 17 types of syndrome, and the syndrome could be classified as deficiency syndrome, excess syndrome, deficiency-excess complication syndrome.Among them, the most common excess syndrome are syndrome of phlegm obscuring and clearing the orifices, and syndrome of blood stasis blocking collaterals, the most common deficiency syndrome are kidney essence deficiency syndrome, liver and kidney deficiency syndrome, qi and blood deficiency syndrome, the most common deficiency-excess complication syndromeis qi deficiency and blood stasis syndrome.(2)The top ten acupoints were Shenting(DU 24), Baihui(DU 20), Sishencong(EX-HN1), Shuigou(DU 26), Zusanli(ST 36), Sanyinjiao(SP 6), Taixi(KI 3), Shenshu(BL 23), Fengchi(CB 20) and Xuehai(SP 10). (3)The most correlated acupoints combination is " DU 20-DU 24-EX-HN1". (4)Cluster analysis yielded atotal of five effective clusters.

The treatment of acupuncture for vascular dementia is based on syndrome differentiation, with " DU 20, -DU 24-EX-HN1" as the main points.The matching points of excess syndrome are " DU 26-DU 14-DU 16, ", " RN 6-SP 10-ST 36, " and add ST 40 and PC 6 according to syndrome differentiation.The matching points of deficiency syndrome are " KI 3-SP 6-BL 23", " SP 10-ST 36", and add Ganshu(BL 18) and Geshu(BL 17) according to syndrome differentiation.Deficiency-excess complication syndrome has the characteristics of both, sothe acupoints mentioned above were applied, to treating deficiency syndrome with tonifying method, as well as treating excess syndrome with purgative method.
