Abstract

To observe the effects of moxibustion at "Zusanli"(ST 36)on oxidative stress and intestinal flora in subacute aging rats, and to explore the possible mechanism of moxibustion in delaying aging. Thirty SD rats were randomly divided into a blank group, a model group and a Zusanli group, with 10 rats in each group. Subacute aging model was established by intraperitoneal injection of D-galactose at dosage of 500 mg/kg in the model group and the Zusanli group, once a day for 42 days. In the Zusanli group, moxibustion was applied at bilateral "Zusanli" (ST 36) , once a day, 3 moxa cones at each acupoint, for consecutive 28 days. After intervention, the serum levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by ELISA; the intestinal flora was detected by 16S rRNA sequencing technique in each group. Compared with the blank group, the serum level of SOD was decreased (P<0.01), the serum level of MDA was increased (P<0.01) in the model group. Compared with the model group, the serum level of SOD was increased (P<0.01), the serum level of MDA was decreased (P<0.01) in the Zusanli group. Compared with the blank group, Chao1 and Shannon indexes were decreased in the model group (P<0.01, P<0.05). Compared with the model group, Chao1 and Shannon indexes were increased in the Zusanli group (P<0.01, P<0.05). Compared with the blank group, the relative abundance of Firmicutes, Treponema_2 and Lachnospiraceae_NK4A136_group was increased (P<0.05, P<0.01), while the relative abundance of Prevotellaceae_UCG-003 and the relative abundance ratio of Bacteroidetes and Firmicutes (B/F value) were decreased (P<0.01, P<0.05) in the model group. Compared with the model group, the relative abundance of Firmicutes and Treponema_2 was decreased (P<0.01), while the relative abundance of Bacteroidetes, Lactobacillus, Prevotellaceae_UCG-003 and B/F value were increased (P<0.05, P<0.01) in the Zusanli group. Moxibustion at "Zusanli"(ST 36)can effectively improve the level of oxidative stress, regulate the constitution of intestinal flora, maintain the microecological balance of intestinal flora in aging rats, and thus play a role in delaying aging.
