Abstract
BACKGROUND
Lung cancer (LC) combined with chronic obstructive pulmonary disease (COPD) is a common combination of comorbidities. Anti-inflammation and modulation of oxidative/antioxidative imbalance may prevent COPD-induced LC, and are also crucial to the treatment of LC combined with COPD. Modern studies have shown that Tao Hong Si Wu Tang (THSW) has vasodilatory, anti-inflammatory, anti-fatigue, anti-shock, immunoregulatory, lipid-reducing, micronutrient-supplementing, and anti-allergy effects.
AIM
To observe the effects of THSW on COPD and LC in mice.
METHODS
A total of 100 specific pathogen-free C57/BL6 mice were randomly divided into five groups: Blank control group (group A), model control group (group B), THSW group (group C), IL-6 group (group D), and THSW + IL-6 group (group E), with 20 mice in each group. A COPD mouse model was established using fumigation plus lipopolysaccharide intra-airway drip, and an LC model was replicated by in situ inoculation using the Lewis cell method.
RESULTS
The blank control group exhibited a clear alveolar structure. The model control and IL-6 groups had thickened alveolar walls, with smaller alveolar lumens, interstitial edema, and several inflammatory infiltrating cells. Histopathological changes in the lungs of the THSW and THSW + IL-6 groups were less than those of the model control group. The serum IL-1β, IL-6, and TNF-α levels and IL-6R, JAK, p-JAK, STAT1/3, p-STAT1/3, FOXO, p-FOXO, and IL-7R expression levels in lung tissues of mice in the rest of the groups were significantly higher than those of the blank control group (P < 0.01). Compared with the model control group, the IL-6 group demonstrated significantly higher levels for the abovementioned proteins in the serum and lung tissues (P < 0.01), and the THSW group had significantly higher serum IL-1β, IL-6, and TNF-α levels and IL-7R expression levels in lung tissues (P < 0.01) but significantly decreased IL-6R, JAK, p-JAK, STAT1/3, p-STAT1/3, FOXO, p-FOXO, and IL-7R levels (P < 0.01).
CONCLUSION
THSW reduces the serum IL-1β, IL-6, and TNF-α levels in the mouse model with anti-inflammatory effects. Its anti-inflammatory mechanism lies in inhibiting the overactivation of the JAK/STAT1/3 signaling pathway.
