Improvement effects and mechanism of Xiangsha yiwei tang on gastric mucosal injury in rats with chronic atrophic gastritis
To investigate the improvement effects and mechanism of Xiangsha yiwei tang on gastric mucosal injury in rats with chronic atrophic gastritis (CAG).
METHODS
2
Rats were randomly assigned into normal control group, model group, Xiangsha yiwei tang low-, medium- and high-dose groups (6, 12, 18 g/kg, calculated by crude drug), and high-dose group of Xiangsha yiwei tang+740 Y-P [Xiangsha yiwei tang 18 g/kg+transforming growth factor β
/PI3K/Akt) pathway activator group 740 Y-P 10 mg/kg
]
, with 18 rats in each group. Rats in each group were administered the corresponding drugs via oral gavage or injection, once daily, for 4 consecutive weeks. Gastric mucosal blood flow, the levels of serum gastroint
estinal hormones [including motilin (MTL), gastrin (GAS), and pepsinogen (PP)
]
, as well as inflammatory cytokines [including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6
]
in rats were measured. Pathological damage to gastric mucosal tissue was observed in rats; the apoptotic rate of gastric mucosal cells was detected. The expressions of TGF-β
1
/PI3K/Akt signaling pathway-related proteins and apoptosis-related proteins [including B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax)
]
in the gastric mucosal tissues of rats were assessed.
RESULTS
2
Compared with normal control group, model group had abnormal gastric mucosal tissue structure, with shedding of gastric mucosal epithelial cells, and prominent infiltration of inflammatory cells. Gastric mucosal blood flow, the serum levels of MTL, GAS, PP, and Bcl-2 protein expression were lowered significantly, while serum levels of TNF-α, IL-1β and IL-6, apoptosis rate, protein expressions of Bax and TGF-β
1
, the phosphorylations of PI3K and Akt were increased significantly (
P
<0.05). Compared with model group, Xiangsha yiwei decoction groups exhibited attenuated histopathological injuries in gastric mucosal tissues, reduced inflammatory cell infiltration, and significant improvements in the aforementioned quantitative parameters (
P
<0.05). Compared with high-dose group of Xiangsha yiwei tang, high-dose group of Xiangsha yiwei decoction combined with 740 Y-P exhibited significantly aggravated histopathological injuries in gastric mucosal tissues, and the aforementioned quantitative parameters were markedly reversed (
P
<0.05).
CONCLUSIONS
2
Xiangsha yiwei tang can alleviate gastric mucosal damage in CAG rats, and its mechanism of action is related to the inhibition of TGF-β
1
/PI3K/Akt signaling pathway.
