Under the current legal framework， living will， as an important legal tool for safeguarding patients’ autonomy and dignity， have been widely recognized and implemented in many countries and regions. In China， the promotion of living will also has a solid legal foundation， with their legitimacy reflected in several provisions of the Civil Code of the People’s Republic of China. One of the highlights of the Medical Regulations of the Shenzhen Special Economic Zone （revised in 2022） is the clarification of the legal effect of living will. To ensure that patients’ living will can be accurately implemented at critical moments， the rights and obligations of patients， family members， and healthcare professionals should be clearly defined within the legal framework， and clear guidance should be provided at every stage of implementation.

Traditional Chinese medicine (TCM) features complex compatibility mechanisms involving multi-component, multi-target, and multi-pathway interactions. This study presents an interpretable graph artificial intelligence (GraphAI) framework to quantify such mechanisms in Chinese herbal formulas (CHFs). A multidimensional TCM knowledge graph (TCM-MKG; https://zenodo.org/records/13763953) was constructed, integrating seven standardized modules: TCM terminology, Chinese patent medicines (CPMs), Chinese herbal pieces (CHPs), pharmacognostic origins (POs), chemical compounds, biological targets, and diseases. A neighbor-diffusion strategy was used to address the sparsity of compound-target associations, increasing target coverage from 12.0% to 98.7%. Graph neural networks (GNNs) with attention mechanisms were applied to 6,080 CHFs, modeled as graphs with CHPs as nodes. To embed domain-specific semantics, virtual nodes medicinal properties, i.e., therapeutic nature, flavor, and meridian tropism, were introduced, enabling interpretable modeling of inter-CHP relationships. The model quantitatively captured classical compatibility roles such as "monarch-minister-assistant-guide," and uncovered TCM etiological types derived from diagnostic and efficacy patterns. Model validation using 215 CHFs used for coronavirus disease 2019 (COVID-19) management highlighted Radix Astragali-Rhizoma Phragmitis as a high-attention herb pair. Mass spectrometry (MS) and target prediction identified three active compounds, i.e., methylinissolin-3-O-glucoside, corydalin, and pingbeinine, which converge on pathways such as neuroactive ligand-receptor interaction, xenobiotic response, and neuronal function, supporting their neuroimmune and detoxification potential. Given their high safety and dietary compatibility, this herb pair may offer therapeutic value for managing long COVID-19. All data and code are openly available (https://github.com/ZENGJingqi/GraphAI-for-TCM), providing a scalable and interpretable platform for TCM mechanism research and discovery of bioactive herbal constituents.

Objective: To investigate the ethical decision-making process of breaking confidentiality when counselors dealing with self-inflicted injury and suicide issues in college situation. Methods: A semi-structural interview was addressed to 10 counselors from 7 college counseling centers in Beijing, among whom with (10 ± 8) years of experience on average in this field. Content analysis method was used to transcription of the interviewing data. Results: Totally 8 counselors had received ethical training more or less, and attached great importance to ethical codes. There were still some conflicts between school regulations and confidentiality rules in 7 university counseling centers. Different counselors varied greatly in decision-making on breaking confidentiality when facing college students' self-inflicted injury and suicide. Faced with conflicts between college demands and confidentiality principles, counselors could take the professional standpoint and consider more of the interests of students. Conclusion: The decision-making process on self-inflicted injury and suicide confidentiality breakthrough needs to be standardized. College's attention and support to the counseling work should be strengthen and enhance ethical awareness.
