ARTICLE HIGHLIGHTS
Research background
Dendrobium officinale is often used to treat stomach diseases. One formula of Granule Dendrobii (GD) consisting of Dendrobium officinale and American ginseng (Radix Panacis quinquefolii) is a potent Traditional Chinese Medicine product in China for chronic atrophic gastritis (CAG) as it reverses gastric mucosa atrophy and improves gastric mucosa intestinal metaplasia (IM).
Research motivation
This study determined the effect of GD treatment on CAG and its potential cellular mechanism to provide a reference for future treatment.
Research objectives
To study the effect and cellular mechanism of GD in the treatment of CAG, and to provide scientific evidence for the clinical application of GD.
Research methods
A rat model of CAG induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) was established, and treatment with GD resulted in weight loss, gastric mucosa atrophy and intestinal metaplasia reversal, as well as changes in PCNA and B-cell lymphoma-2 (Bcl-2) after 8 wk of treatment.
Research results
Treatment with GD for 8 wk resulted in significant improvements in body weight, gastric mucosal inflammation, atrophy, and IM in rats with CAG induced by MNNG. GD also increased the reduced levels of hemoglobin and erythrocytes in CAG rats.
Research conclusions
GD improved gastric mucosal lesions and the secondary pathological changes of CAG including hemoglobin and red blood cell reductions, and overall body condition. GD also alleviated the overexpression of PCNA and Bcl-2 in model rats, which maybe one of the therapeutic mechanisms related to the reduction in gastric mucosal inflammation and mucosal damage.
Research perspectives
Our research group will continue to confirm whether the effect of GD can be duplicated in CAG patients by clinical studies with large sample sizes, strict control and rigorous experimental design, and further study the molecular and cellular mechanism of GD.
