Tetramethylpyrazine promotes osteo-angiogenesis during bone fracture repair.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNonunion following a long bone fracture has gained a lot of attention due to the dreadful impact on the life quality of tremendous patients. Recent data have demonstrated the important involvement of angiogenesis in improving fracture healing. Tetramethylpyrazine (TMP) is an active component of Chinese herbal medicine with various biological activities including pro-angiogenesis property. However, the activity and mechanism of action of TMP in osteo-angiogenesis during bone fracture repair bone fracture healing remain unknown. In this study, TMP was tested for its specific activities in rat aortic endothelial cells (RAECs) and fractured rat model.
methodsThe effect of TMP on angiogenesis and migration in RAECs was detected by conducting matrigel tubulogenesis assay and transwell assay. Histopathological changes were observed in the rats from each group using H&E staining. The levels of inflammation and coagulation markers in rats were evaluated by ELISA. The expression of osteogenesis-related genes in rats was assessed by RT-qPCR and western blotting.
resultsTMP promoted angiogenesis processes and migratory ability in RAECs. TMP improved histopathological changes in fractured rat model. The concentration of inflammatory markers (IL-2, IL-6, IL-1beta) in the serum of fractured rats were suppressed by TMP treatment. TMP also had the potential to inhibit blood coagulation in rat tibia fracture model. In addition, the expression and protein levels of osteogenesis-related markers (ALP, Runx2, and OPN-1) were elevated by TMP in the tissues from the fractured rats. In mechanism, TMP significantly promoted the activation of VEGF/FLK1 pathway in vitro and in vivo.
conclusionTMP accelerated the repair of bone fracture by promoting angiogenesis and osteogenesis.
