Improvement of intestinal flora: accompany with the antihypertensive effect of electroacupuncture on stage 1 hypertension.


ABSTRACT:

Background

Increasing evidence have indicated the relationship between intestinal dysbiosis and hypertension. We aimed to evaluate the effect of the electroacupuncture (EA) on intestinal microbiota in patients with stage 1 hypertension.

Methods

93 hypertensive patients and 15 healthy subjects were enrolled in this study. Applying a highly accurate oscillometric device to evaluate the antihypertensive effect of EA. 16S rRNA sequencing was used to profile stool microbial communities from Healthy group, Before treatment (BT) group and After treatment (AT) group, and various multivariate analysis approaches were used to assess diversity, composition and abundance of intestinal microbiota.

Results

In this study, EA significantly decreased the blood pressure (BP) of hypertensive patients. Higher abundance of Firmicutes and lower Bacteroidetes abundance were observed in the BT group compared to the Healthy group. And EA treatment significantly decreased the Firmicutes/Bacteroidetes ratio compared to the BT group. Moreover, at the genus level, there was an increased abundance of Escherichia-Shigella in patients with hypertension, while Blautia were decreased, and EA reversed these changes.

Conclusions

Our study indicates that EA can effectively lower BP and improve the structure of intestinal microbiota which are correlate with the alteration of blood pressure by electroacupuncture.
