Key result
Panax notoginseng significantly reduced thrombus formation and downregulated the mRNA expression of autophagy markers Beclin1, P62, and LC3 (p<0.05) in a rat model of deep vein thrombosis.
Why the study?
To establish a rat model of deep vein thrombosis via inferior vena cava ligation and investigate the intervention effect of Panax notoginseng on autophagy.
Does Panax notoginseng reduce thrombosis and inhibit autophagy in a rat model of deep vein thrombosis?

p-value: p=<0.05
Panax notoginseng reduces thrombosis formation in a rat model of deep vein thrombosis, potentially by inhibiting the autophagy process.
May inhibit autophagy and thrombosis in rat DVT; hypothesis-generating and should not change practice.
Objective To establish a rat model of deep vein thrombosis (DVT) via the ligation of the inferior vena cava and investigate the intervention effect of Panax notoginseng (PN) on autophagy in DVT rats. Methods A rat model of DVT was established, and the rats were treated with PN and low-molecular-weight heparin (enoxaparin sodium injection) to observe the effect of PN on autophagy. Results In the model group, hematoxylin and eosin (H&E) staining revealed high levels of thrombosis and inflammatory cell infiltration. In the model group, Beclin1 , P62 , and LC3 mRNA expression was significantly increased. The P-selectin content increased significantly, and the red blood cell count and hemoglobin level decreased significantly. In the model + PN (M + PN) group, H&E staining revealed reduced thrombosis formation; a small area of recanalization was observed, and one sample showed no obvious thrombosis. Beclin1 , P62 , and LC3 mRNA expression was significantly downregulated. H&E staining revealed reduced thrombus formation in the model + low-molecular-weight heparin (M + LMWH) group compared with the model group; neither M + LMWH sample showed obvious thrombus formation. However, only LC3 mRNA expression was downregulated. The content of P-selectin was decreased and the red blood cell count was increased. Conclusion DVT rats exhibited autophagy, and PN improved DVT by inhibiting the autophagy process.

Wang et al. (2023) studied Deep vein thrombosis (n=20). Panax notoginseng vs. 0.9% sodium chloride was evaluated on mRNA expression of Beclin1, P62, and LC3 (p=<0.05). Panax notoginseng significantly reduced thrombus formation and downregulated the mRNA expression of autophagy markers Beclin1, P62, and LC3 (p<0.05) in a rat model of deep vein thrombosis.
