Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide (LPS)-induced acute lung injury (ALI), and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid (AA) in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight: normal group, model group, dexamethasone group (2 mg·kg-1), low-dose Yantiao prescription group (18 g·kg-1), and high-dose Yantiao prescription group (36 g·kg-1), with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days, and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to assess lung tissue pathology. The wet/dry weight ratio (W/D) and myeloperoxidase (MPO) activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry (LC-MS/MS). ResultsCompared with the conditions in the normal group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the model group was significantly increased (P<0.01). The alveolar structure in mice was severely damaged, with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased (P<0.01). The content of AA metabolites, including prostaglandin D2 (PGD2), prostaglandin E2 (PGE2), 11(S)-hydroxy-eicosatetraenoic acid [11(S)-HETE], and 5-hydroxy-eicosatetraenoic acid (5-HETE) in serum and lung tissue was significantly increased (P<0.05), while the content of 11,12-epoxyeicosatrienoic acid (11,12-EET) and 14,15-epoxyeicosatrienoic acid (14,15-EET) in serum was significantly decreased (P<0.01). Compared with the results in the model group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the dexamethasone group, low-dose Yantiao prescription group, and high-dose Yantiao prescription group was significantly reduced (P<0.05). Mild thickening of alveolar walls, scattered inflammatory cell infiltration, and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced (P<0.01). The content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum from the dexamethasone group was significantly decreased (P<0.05), while the content of 14,15-EET in serum significantly increased (P<0.01), and the content of 5-HETE in lung tissue significantly decreased (P<0.01). In the low-dose and high-dose Yantiao prescription groups, the content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum and lung tissue was significantly decreased (P<0.05), while the content of 11,12-EET in both serum and lung tissue was significantly increased (P<0.05). ConclusionYantiao prescription has significant protective effects against LPS-induced ALI, which are related to its regulation of AA metabolic pathways in vivo.

Objective:To investigate the current status and challenges in legal compliance regarding the collection, utilization, sharing, cross-border transfer, and disposal of human genetic resources (HGR) in international collaboration agreements, and to explore key review points for medical institutions in international cooperation agreements to mitigate legal risks and ensure compliance in HGR-related global collaborations.Methods:We reviewed international collaborative research projects involving Peking University Cancer Hospital that were approved or filed on the National Health Commission (NHC) Administrative Service Platform between July 2019 and April 2025, analyzed the utilization of human genetic resources (HGR) materials and information in these studies, assessd compliance clauses in international agreements related to HGR management, identified gaps, and proposed actionable recommendations.Results:A total of 410 international cooperation projects on human genetic resources were analyzed, of which 302 cooperation agreements signed with sponsors stipulated that research should obtain administrative approval or complete filing for human genetic resources before implementation(73.7%). However, 113 agreements had errors in citing legal provisions or incomplete agreements. A mtotal of 385 studies involved human genetic resource materials, of which 277 agreed on the compliant use of biological samples, but mainly focused on the collection and testing process, with insufficient agreements on the disposal of remaining samples. Some agreements only stipulate that ″compliant collection and use of samples″ is the sole responsibility of medical institutions, ignoring the relevant responsibilities of the sponsor, and the risk allocation is unreasonable. 361 studies involved human genetic resources information, but only 72 explicitly agreed that China′s human genetic resources information should be collected, preserved, used and shared within the approved scope of human genetic resources (less than 20%).Conclusions:The expression of human genetic resources related content in most agreements is not standardized; The management agreement for human genetic resources materials is incomplete and does not cover the entire cycle of sample processing; The responsibilities that the applicant should bear in the cooperation are unclear; The management of human genetic resource information is easily overlooked. It is recommended that medical institutions closely monitor changes in relevant laws, regulations, and management methods, and update the corresponding clauses of the agreement in a timely manner, and improve the situations that should be submitted for administrative approval or filing in the agreement; All parties involved in the cooperation should make compliance commitments for human genetic resources; Clearly stipulate the full cycle management of human genetic resources materials; Pay attention to risk prevention and control in the management of human genetic resources information; Pay attention to the systematic coverage of intellectual property types and the operability of rights implementation in international cooperation.

Objective:To explore the safety and efficacy of intraosseous regional administration (IORA) of vancomycin for preventing infection in primary total knee arthroplasty (TKA).Methods:A total of 124 patients with knee osteoarthritis undergoing TKA between February 2024 and May 2024 at nine hospitals were enrolled. Preoperative infection prophylaxis involved either IORA (0.5 g vancomycin administered via intraosseous regional infusion before incision) or intravenous infusion (1 g vancomycin via peripheral vein). The IORA group included 15 males and 47 females with a median age of 66.5 years (range, 60.0-70.0 years), while the intravenous group included 14 males and 48 females with a median age of 66.0 years (range, 61.8-70.3 years) years. Intraoperative samples were collected including fat and synovium tissues after incision, before prosthesis placement, and after tourniquet release; distal femoral cancellous bone during femoral osteotomy; proximal tibial cancellous bone during tibial osteotomy; proximal intercondylar cancellous bone before prosthesis placement; and peripheral blood from non-infused arms at surgery initiation and after tourniquet release. Vancomycin concentrations were measured using liquid chromatography-tandem mass spectrometry. Vital sign changes were recorded from admission to 5~10 minutes post-IORA (IORA group) or post-incision (intravenous group). Follow-ups were conducted on postoperative day 1 and 3, and at 1 and 3 months, to document complications including IORA-related adverse events, periprosthetic joint infections, surgical site infections, red man syndrome, acute kidney injury, deep vein thrombosis and so on.Results:Vancomycin concentrations in bone, fat, and synovial tissue samples were significantly higher in the IORA group than in the intravenous group ( P<0.05), while vancomycin concentrations in blood samples were significantly lower in the IORA group than in the intravenous group ( P<0.05). Only 7.3%(41/558) of tissue samples in the IORA group had vancomycin concentrations below 2.0 μg/g (the minimum inhibitory concentration of vancomycin against coagulase-negative staphylococcus), compared to 59.3%(331/558) in the intravenous group (χ 2=11.285, P<0.001). In the intravenous group, 16.9%(21/124) of blood samples had vancomycin concentrations exceeding 15.0 mg/L (the threshold associated with a significantly increased risk of nephrotoxicity), while all concentrations in the IORA group were below this threshold, the difference was statistically significant (χ 2=22.943, P<0.001). There were no statistically significant difference ( P>0.05) in vital signs changes before and after vancomycin administration between the two groups. Two patients in the intravenous group experienced incision exudate, while no other related complications occurred in either group. Conclusions:Compared to the traditional intravenous infusion of 1 g vancomycin, intraosseous injection of a low dose (0.5 g) of vancomycin achieves higher local tissue concentrations in the knee joint with a lower incidence of adverse reactions and is safe for infection prophylaxis. Despite guidelines not recommending the routine use of vancomycin for preventing infection after primary TKA, intraosseous injection of 0.5 g vancomycin may be considered intraoperatively for primary TKA in the following scenarios: patients in medical institutions with a high prevalence of methicillin-resistant staphylococcus aureus (MRSA) infections, patients with potential preoperative MRSA colonization, or patients with cephalosporin allergy.
