Da Qinjiaotang is a common classical prescription for the treatment of stroke. It originates from Collection of Writings on the Mechanism of Disease, Suitability of Qi, and the Safeguarding of Life as Discussed in the Basic Questions (《素问病机气宜保命集》) by physician LIU Wansu, and is composed of Gentianae Macrophyllae Radix, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Angelicae Sinensis Radix, Paeoniae Radix Alba, Asari Radix et Rhizoma, Notopterygii Rhizoma et Radix, Saposhnikoviae Radix, Scutellariae Radix, Gypsum Fibrosum, Angelicae Dahuricae Radix, Atractylodis Macrocephalae Rhizoma, Rehmanniae Radix, Rehmanniae Radix Praeparata, Poria, and Angelicae Pubescentis Radix. Doctors of all dynasties have disputed the composition principle of the prescription and argued whether its treatment of stroke belongs to the theory of "internal wind" or "external wind". Through collating and analyzing ancient and modern literature related to the indications of Da Qinjiaotang, this paper was dedicated to the origin of syndrome differentiation and treatment of Da Qinjiaotang. According to LIU Wansu's original works, Da Qinjiaotang is a prescription for the treatment of "internal wind", and in the prescription, wind medicinal herbs such as Gentianae Macrophyllae Radix, Notopterygii Rhizoma et Radix and Angelicae Pubescentis Radix removes stagnation, clears sweat pore, and makes qi and blood channels flow smoothly. However, later generations, affected by the idea of "external wind", believe that this prescription is used for the treatment of "external wind". Ancient physicians gradually supplemented the symptoms of stroke, such as wry eye and mouth, hemibody pain and limb numbness, which were treated by Da Qinjiaotang, and Da Qinjiaotang was also applied to the treatment of other diseases, such as tendon dryness, convulsion and arthralgia. Modern doctors still explain the disease pathogenesis from the theory of "external wind" as deficiency in channels and collaterals and the entry of pathogenic wind, and the prescription has the effect of dispersing wind, clearing heat and nourishing and activating blood. In clinical practice, Da Qinjiaotang is mainly used to treat cerebrovascular diseases and peripheral facial paralysis in nervous system diseases, gouty arthritis and rheumatic arthritis in the rheumatic immune system and skin diseases. The above findings facilitate the research and development of Da Qinjiaotang.

ObjectiveThis study aims to develop a prediction model for the compatibility of Chinese medicinal pairs based on Graph Convolutional Networks (GCN), named HC-GCN. The model integrates the properties of herbs with modern pharmacological mechanisms to predict pairs with specific therapeutic effects. It serves as a demonstration by applying the model to predict and validate the efficacy of blood-activating herb pairs. MethodsThe training dataset for herb pair prediction was constructed by systematically collecting commonly used herb pairs along with their characteristic data, including Qi, flavor, meridian tropism, and target genes. Integrating traditional characteristics of herb with modern bioinformatics, we developed an efficacy-oriented herb pair compatibility prediction model (HC-GCN) using graph convolutional networks (GCN). This model leverages machine learning to capture the complex relationships in herb pair compatibility, weighted by efficacy features. The performance of the HC-GCN model was evaluated using accuracy (ACC), recall, precision, F1 score (F1), and area under the ROC curve (AUC). Its predictive effectiveness was then compared to five other machine learning models: eXtreme Gradient Boosting (XGBoost), logistic regression (LR), Naive Bayes, K-nearest neighbor (KNN), and support vector machine (SVM). ResultsUsing herb pairs with blood-activating effects as a demonstration, a prediction model was constructed based on a foundational dataset of 46 blood-activating herb pairs, incorporating their Qi, flavor, meridian tropism, and target gene characteristics. The HC-GCN model outperforms other commonly used machine learning models in key performance metrics, including ACC, recall, precision, F1 score, and AUC. Through the predictive analysis of the HC-GCN model, 60 herb pairs with blood-activating effects were successfully identified. Among of these potential herb pairs, 44 include at least one herb with blood-activating effects. ConclusionIn this study, we established an efficacy-oriented compatibility prediction model for herb pairs based on GCN by integrating the unique characteristics of traditional herbs with modern pharmacological mechanisms. This model demonstrated high predictive performance, offering a novel approach for the intelligent screening and optimization of traditional Chinese medicine prescriptions, as well as their clinical applications.
