Softening hard masses and dissipating stagnation (RJSJ)

Softening hard masses and dissipating stagnation (known as Ruanjian Sanjie in Chinese) is a foundational therapeutic principle in Traditional Chinese Medicine (TCM) used to treat various hard pathological masses, including malignant tumors, cysts, and goiters [2]. It is not a specific molecular target or receptor but a therapeutic category of herbal formulations, such as the Ruanjian Sanjie decoction, which typically includes medicinal herbs like Prunella vulgaris and Sargassum [4][5]. These formulations work synergistically to resolve phlegm, eliminate blood stasis, and soften hardened tissues through multiple biological pathways rather than a single site of action [2]. In oncology, this principle is applied to induce tumor cell apoptosis and sensitize cancer cells to conventional therapies like chemotherapy and radiotherapy while reducing systemic toxicity [4][6]. Clinically, it is frequently employed for the management of breast cancer, thyroid hyperplasia, and uterine fibroids, demonstrating a broad spectrum of anti-proliferative and anti-inflammatory activities in modern pharmacological studies [3][5].

The mechanism involves the suppression of anti-apoptotic proteins such as Bcl-2 and survivin, leading to the activation of the caspase-3/7 and caspase-9 apoptotic cascades [2][4]. Formulations based on this principle also target pathways involved in cell proliferation and invasion, including the inhibition of the PI3K/Akt/mTOR and Wnt/β-catenin signaling pathways, and the regulation of the Smad3/Smad7 cascade to inhibit epithelial-mesenchymal transition [3][5][6].
