ObjectiveTo investigate the potential therapeutic effects of Dengzhan Shengmai capsules (DZSM) on myocardial fibrosis after myocardial infarction and decipher the underlying molecular mechanisms by virtue of network robustness algorithm. MethodsA rat model of myocardial infarction was established by ligating the left anterior descending coronary artery. Successfully modeled Sprague-Dawley rats were randomly allocated into a model group, an enalapril group(3.15 mg·kg-1), and high- and low-dose DZSM groups(226.8,113.4 mg·kg-1). In addition, a sham group was set up. After four consecutive weeks of intervention, the cardiac function was assessed via echocardiography, and myocardial collagen deposition was observed through Sirius red staining. The key regulatory pathways of DZSM were analyzed by the network robustness algorithm. Enzyme-linked immunosorbent assay (ELISA) and immunofluorescence assay were employed to validate the mechanisms. ResultsCompared with the sham group, the model group exhibited decreased left ventricular ejection fraction (LVEF%) and fractional shortening (FS%) (P<0.01) and increased myocardial collagen volume fraction (CVF%) (P<0.01). Compared with the model group, high-dose DZSM and enalapril improved LVEF% and FS% (P<0.01). Both high- and low-dose DZSM reduced the CVF% (P<0.05, P<0.05,). Network analysis indicated that DZSM exerted its effects by regulating neutrophil infiltration and related inflammatory pathways. Experimental validation showed that DZSM significantly reduced the protein levels of nuclear factor (NF)-κB, Janus kinase 2 (JAK2), and signal transduction activator and transducer 3 (STAT3) in the cardiac tissue, as well as the levels of chemokine (C-X-C motif) ligand 1 (CXCL1), interleukin (IL)-1β, neutrophil elastase-DNA complex (NE-DNA), and myeloperoxidase-DNA complex (MPO-DNA) in the plasma. ConclusionDZSM may ameliorate myocardial fibrosis by inhibiting neutrophil infiltration and extracellular trap formation and regulating the NF-κB/JAK2/STAT3 signaling pathway.

Lianpo Yin was first recorded in the Revised Treatise on Cholera from Suixi Residence by WANG Mengying. It is composed of seven medicinal herbs: Coptidis Rhizoma, Magnoliae Officinalis Cortex, Sojae Semen Praeparatum, Acori Tatarinowii Rhizoma, Pinelliae Rhizoma, Gardeniae Fructus, and Phragmitis Rhizoma. As one of the classic prescriptions for clearing heat, resolving dampness, regulating Qi, and harmonizing the middle energizer, it has been included in the Catalogue of Ancient Classic Prescriptions (Second Batch: Han Chinese Medicine) published by the National Administration of Traditional Chinese Medicine in 2023. Lianpo Yin is primarily indicated for cholera caused by the accumulation of dampness-heat, and it can promote digestion and eliminate phlegm. By summarizing the ancient literature records, chemical constituents of individual herbs and the compound formula, pharmacological effects, and modern clinical applications of Lianpo Yin, this paper discovers that the understandings of most ancient physicians are consistent with the original text. The pathogenesis treated by this prescription is generally attributed to the accumulation of dampness-heat in the middle energizer and disrupted ascending and descending of Qi. The main chemical components of this prescription include coptisine, trigonelline, genistein, palmatine, berberine, honokiol, and magnolol. Lianpo Yin exhibits pharmacological effects such as anti-inflammatory activity, regulation of apoptosis, modulation of mitochondrial autophagy, regulation of the hypothalamic-pituitary-adrenal (HPA) axis, promotion of gastrointestinal motility, improvement of the gastric mucosal barrier, regulation of intestinal flora and their metabolites, and antimicrobial activity. In modern clinical practice, this prescription is mainly used to treat digestive system diseases such as chronic superficial gastritis and Helicobacter pylori (Hp)-associated gastritis. Additionally, it demonstrates significant therapeutic effects on various diseases affecting the nervous, respiratory, dermatological, and cardiovascular systems. This study provides a detailed review of the ancient literature records, chemical components, pharmacological effects, and clinical applications of Lianpo Yin and its modified formulas, aiming to offer references for the dosage form development and broader clinical application of this classic prescription.

ObjectiveTo enhance teaching in postoperative cancer rehabilitation, this study developed an integrative Chinese-Western medicine postoperative oncology rehabilitation system, termed the medical oncology generative pre-trained transformer (MedOncoGPT). By introducing MedOncoGPT as an intelligent assistant, an integrated teaching model combining Chinese and Western medicine was established. The study evaluated its impact on students’ integrative clinical reasoning and practical abilities, providing support for instructional reform in related courses. MethodsUsing teaching resources as the knowledge base, MedOncoGPT was built upon the open-source ChatGLM model and incorporated Low-Rank Adaptation (LoRA) fine-tuning and retrieval-augmented generation (RAG) techniques to address postoperative integrative oncology scenarios. The system was applied in courses and clinical clerkships related to integrative oncology. In alignment with course objectives, a five-stage instructional process—pre-class preparation, in-class inquiry, simulated multidisciplinary consultation, clinical reinforcement, and teaching reflection—was designed to guide students in completing syndrome differentiation, comprehensive assessment, and follow-up planning within real or simulated case contexts. Comparative analyses of student engagement, syndrome differentiation thinking, evidence-based awareness, and interdisciplinary integration skills before and after the teaching reform were conducted using questionnaires, course assessments, classroom observations, and semi-structured interviews. ResultsFollowing the implementation of MedOncoGPT, students demonstrated improved performance in case analysis, prescription formulation, and integrative Chinese-Western medical evaluation compared with those receiving traditional instruction. Classroom participation and the relevance of student inquiries also increased. Self-assessment results indicated high levels of satisfaction with respect to clarity of integrative clinical reasoning, ability to retrieve and apply guideline-based evidence, and awareness of appropriate use of intelligent tools in clinical decision-making. More than 92% of students reported that the system facilitated understanding of abstract theoretical concepts presented in textbooks. Instructors noted that the system helped reduce lesson preparation time, enriched typical case materials and discussion scenarios, and promoted the translation of research findings into classroom teaching. Pilot data showed that, with MedOncoGPT assistance, the mean time for initial syndrome differentiation decreased from 18.4 min to 12.1 min, and the agreement rate increased from 68.3% to 82.5%. In the teaching pilot, the experimental group achieved a higher mean score on the final case analysis assessment than the control group (82.6 vs. 74.3). ConclusionThe integration of MedOncoGPT into teaching on postoperative integrative cancer rehabilitation enabled the establishment of a stable instructional process within existing curricula and enhanced students’ integrative clinical reasoning and evidence-based practice capabilities. The approach demonstrates positive potential for advancing the integration of research, clinical practice, and education and represents a valuable exploratory strategy for instructional reform in courses on integrative Chinese-Western medicine.

OBJECTIVE To develop a pharmaceutical service model for discharge medication order review and medication education (hereinafter referred to as the “proactive pharmaceutical service model”), and evaluate its effects. METHODS The data of discharged patients were collected retrospectively from Rheumatology and Immunology Department of our hospital during January to June 2023 and January to June 2024. Patients discharged from January to June 2024 were classified as the intervention group (489 cases), while patients discharged from January to June 2023 were classified as the control group (535 cases) based on the different pharmaceutical service models they received. The control group received traditional service model, and the intervention group additionally got proactive pharmaceutical service model based on the control group. The primary outcome measures [the number of discharge medications, the number of medication errors, and the occurrence of adverse drug-drug interaction (DDI)] and follow-up outcome measures (the adjustment of medication regimen due to intolerance, unplanned hospital admissions, and proactive seeking of pharmaceutical services after discharge) were compared between the two groups. The discharge medication order review status, the occurrence of adverse DDI in patients with polypharmacy, and bedside medication education status for patients receiving the proactive pharmaceutical service model were all recorded. RESULTS From January to June 2024, a total of 1 052 discharge medication order review for inpatients were reviewed, and 174 instances of medication errors were identified. Polypharmacy was observed in 579 patients, with an incidence rate of 55.04%. The incidence of adverse DDI was significantly higher in patients with polypharmacy compared to those without polypharmacy (P<0.001). Pharmacists completed medication guidance for 394 instances of high-risk patients prone to the incidence rate of medication errors at home. The number of discharge medications, the incidence rate of medication errors, instances of medication not matching the diagnosis, dosage and administration errors, adverse DDI, and the incidence rate of patients who required adjustment of medication regimen due to intolerance were all significantly lower in the intervention group compared to the control group (P<0.05). Additionally, the incidence rate of patients who proactive seeking of pharmaceutical services after discharge was significantly higher in the intervention group compared to the control group (P<0.05). However, there was no significant difference in the incidence rate of unplanned hospital admissions between the two groups (P>0.05). CONCLUSIONS The established proactive pharmaceutical service model can reduce medication errors, enhance patient recognition of pharmaceutical services, and ensure medication safety for discharged patients at home.
