Effect of Modified Guipitang Combined with Xingnao Kaiqiao Acupuncture in Treatment of Heart and Spleen Insufficiency Syndrome of Non-dementia Vascular Cognitive Impairment / 中国实验方剂学杂志

ABSTRACT

Objective: To explore the curative effect and partial mechanism of modified Guipitang combined with Xingnao Kaiqiao acupuncture in the treatment of non-dementia vascular cognitive impairment (VCIND). Method: Totally 122 patients with VCIND admitted to the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine (TCM) from May 2017 to October 2018 were randomly divided into modified decoction group (39 cases), acupuncture group (42 cases) and combination group (41 cases). All of the three groups were orally given routine anticoagulants and lipid-lowering drugs. The decoction group was orally given modified Guipitang 150 mL/times, 2 times/day, in addition to the routine treatment, the acupuncture group was treated with Xingnao Kaiqiao acupuncture method in addition to the routine treatment, involving Shuigou, Neiguan (bilateral), Sanyinjiao (bilateral), Sishencong, Xuanzhong (bilateral) and Taixi (bilateral) acupoints, 2 times/day, for six days a week, the combined group was treated with Xingnao Kaiqiao acupuncture in addition to modified Guipitang. All of the three groups were treated for 8 weeks. The Montreal cognitive assessment scale (MoCA scale, Beijing version) and activity of daily life (ADL) scale, TCM symptoms and clinical efficacy were scored before treatment, 4 weeks after treatment and 8 weeks after treatment in three groups. Serum levels of calcitonin gene-related peptide (CGRP) and cone-like protein-1 (VILIP-1) were measured by enzyme-linked immunosorbent assay at different time points. Result: Compared with decoction group and acupuncture group, MoCA score, ADL score and TCM syndrome score of the combined group were decreased, the total effective rate was increased significantly after 4 and 8 weeks of treatment, the serum CGRP content was increased, and the VILIP-1 content was decreased. Conclusion: Modified Guipitang combined with Xingnao Kaiqiao acupuncture has a definite curative effect on VCIND with heart and spleen insufficiency syndrome. Its mechanism may be related to the expansion of blood vessels, the alleviation of blood supply of brain and the reduction of neuron injury.
