Abstract
Dan Shen extracts have been reported for centuries to control cardiovascular diseases in Chinese medicine, and its depside salts are approved in China to treat chronic angina. As the most abundant active compound of Dan Shen, salvianolic acid B (SAB) has been shown to exhibit anti-thrombotic properties in animal models. However, its mechanism of action has not been adequately explored. Interestingly, we found SAB bears structural similarities to dabigatran. SAB reduced clot weight, delayed coagulation determined by PT, aPTT, and TEG. Confocal and scanning electron microscopy revealed SAB also reduced fibrin network density. We demonstrated SAB attenuates ADP- and collagen-induced platelet aggregation. Remarkably, SAB inhibits thrombin-induced platelet aggregation more potently than other agonists. Ex vivo perfusion chamber studies showed SAB reduced platelet adhesion/aggregation under flow conditions. These data establish a novel mechanism of SAB in the inhibition of platelet aggregation and blood coagulation, likely partially through direct thrombin inhibition.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
