OBJECTIVE To explore the improvine mechanism of Yifei xuanfei jiangzhuo formula (YFXF) on vascular dementia (VAD) model rats based on the growth factor receptor-bound protein 2 (GRB2)/extracellular signal-regulated kinase (ERK)/cardiolipin synthase 1 (CRLS1) pathway. METHODS VAD rat model was established by permanent bilateral common carotid artery ligation. Forty-eight successfully modeled rats were randomly divided into the model group (normal saline), donepezil hydrochloride group (positive control group, 0.2 g/kg), and YFXF low- and high-dose groups (12.18 and 24.36 g/kg, calculated based on the total amount of crude drug), respectively. In addition, a sham operation group (normal saline) was set up. There were 12 rats in each group. Daily intragastric administration of drug or normal saline was performed for 30 consecutive days. After the last administration, the spatial cognitive ability of the rats was evaluated, the pathological morphology of the hippocampus was observed, the contents of tumor necrosis factor-α (TNF-α) and interleukin-4 (IL-4) in serum were detected, the expression levels of GRB2/ERK/CRLS1 pathway-related proteins and the mRNA levels of GRB2, CRLS1, NADH dehydrogenase subunit 1(ND1), Tafazzin (TAZ), phospholipid scramblase 3(PLSCR3) and the ATP content in hippocampal tissue were measured. RESULTS Compared with the sham operation group, the escape latency of rats in the model group was significantly prolonged ( P <0.05), and the number of crossing platform was significantly reduced ( P <0.05), while the number of pyramidal cells and Nissl bodies in the hippocampus decreased sharply; the content of TNF-α in serum was significantly increased ( P <0.05), and the content of IL-4 was significantly decreased ( P <0.05); the expression levels of GRB2 and CRLS1 proteins, the phosphorylation level of ERK protein, the relative expression levels of GRB2, CRLS1,ND1, TAZ, and PLSCR3 mRNA, and the content of ATP in hippocampal tissue were significantly decreased ( P <0.05). Compared with the model group, the above pathological changes in the hippocampal tissue of each administration group were alleviated, and the quantitative indicators were significantly restored ( P <0.05). CONCLUSIONS YFXF may improve hippocampal neuron injury in VAD rats by activating the GRB2/ERK/CRLS1 pathway, maintaining cardiolipin homeostasis, and improving mitochondrial energy metabolism.

OBJECTIVE:
To develop a user-friendly visualization application for the automatic annotation of Human Phenotype Ontology (HPO) terms based on large language models and retrieval-augmented generation (RAG) technology, and to validate its performance in an authoritative case dataset.
METHODS:
By integrating the domestic open-source large language model DeepSeek-V3 with RAG technology, an interactive web application was deployed on the Streamlit cloud platform. Using only the latest official HPO dataset as the data source, the lightweight sentence-embedding model BAAI/bge-small-en-v1.5 was employed to construct a FAISS vector index. During the online phase, a four-step closed-loop process is automatically completed: multilingual translation, phenotype phrase extraction, RAG candidate retrieval, term mapping, and official database validation. 121 English case reports publicly released by BMJ Case Reports and Oxford Medical Case Reports (with a gold-standard HPO set of 1 794 terms) were selected for application validation. Precision, recall, and F1 score were calculated and compared horizontally with traditional dictionary tools, standalone large language models, and the similar application "RAG-HPO". Finally, replace the model with the more advanced ChatGPT-5 and evaluate its performance on the newly extracted dataset.
RESULTS:
An HPO term automatic annotation visualization application named PhenoRAG, based on large language models and RAG technology, was successfully developed. Users can access it directly via a web link. Across the 112 cases, a total of 2 150 HPO terms were generated; 2,064 (96.0%) were fully validated by the official database, with a hallucination rate of 1.3% and an HPO ID-name mismatch rate of 2.7%. After deduplication, 1,906 terms remained for testing. The overall precision was 63.65%, recall was 67.34%, and F1 was 65.44%, significantly outperforming traditional annotation tools (F1: 0.45-0.49, P < 0.001). Although PhenoRAG's F1 was lower than that of RAG-HPO (F1 = 0.78, P < 0.001), which relies on a manually constructed synonym database of 54 000 entries plus the HPO dataset, it requires no additional dictionary maintenance and can be used without any background in computer programming. Moreover, after switching to the GPT-5 model, PhenoRAG exhibited no hallucination rate on the new dataset, and its F1 score significantly increased (P = 0.038).
CONCLUSION
Without constructing a synonym database, the PhenoRAG achieved high-accuracy automatic mapping from clinical text to standard HPO terms. It features a low usage threshold, free access, and a Chinese-language interface, and can directly serve rare disease diagnosis, genetic counseling, and research scenarios in China and worldwide, warranting further clinical promotion and multicenter validation.

Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2<BMI≤23 kg/m2), a group B (23 kg/m2<BMI≤29 kg/m2) and a group C (BMI>29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

Objective To investigate the risk factors associated with mortality in patients undergoing surgical treatment for myocardial infarction complicated by ventricular septal rupture, and to establish a prediction model. Methods A retrospective analysis was conducted on clinical data of patients who underwent surgical treatment of myocardial infarction with ventricular septal rupture at Beijing Anzhen Hospital from 2008 to 2022. Patients were followed up and divided into a survival group and a death group based on perioperative and follow-up outcomes. Univariate analysis was performed for all variables, followed by least absolute shrinkage and selection operator (LASSO) regression to screen risk factors affecting postoperative mortality. A Cox regression model was constructed and a Nomogram was developed. Results A total of 83 surgical patients were included, comprising 49 males and 34 females, with a mean age of (64.4±7.7) years. There were 13 perioperative deaths, and among the 70 surviving patients, 6 additional deaths occurred during follow-up. Consequently, 64 patients were assigned to the survival group and 19 to the death group. Univariate analysis revealed statistically significant differences between groups in age, culprit vessel patency status, intra-aortic balloon pump use, Killip classification, time from myocardial infarction to surgery, and time from perforation to surgery (all P<0.05). LASSO regression identified three independent predictors: age [HR=1.092, 95%CI (1.005, 1.187), P=0.039], Killip classification [HR=2.024, 95%CI (1.009, 4.059), P=0.047], and culprit vessel patency [HR=0.110, 95%CI (0.014, 0.869), P=0.036]. The Nomogram based on these variables demonstrated good discriminative ability, with area under the receiver operating characteristic curve of 0.907 at 1 month and 0.876 at 1 year postoperatively. Follow-up revealed cumulative survival rates of 78.2%, 78.2%, 74.6%, and 74.6% at 2, 5, 8, and 10 years postoperatively for all patients, and 92.7%, 92.7%, 88.5%, and 88.5% for perioperative survivors. Conclusion Patients with myocardial infarction complicated by ventricular septal rupture demonstrate favorable mid-to-long-term prognosis after surgical repair. Age, Killip classification, and culprit vessel patency are independent predictors of postoperative mortality, and the established prediction model shows satisfactory prognostic performance.

Objective To investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. The laboratory results, perioperative blood component infusion volume, and other relevant parameters were retrospectively analyzed. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 52 males and 50 females, with an average age of (61.74±10.58) years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). Group 1 had the highest postoperative Hb, as well as the highest Hb and hematocrit (HCT) levels within 24 hours post-surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss and total drainage volume (P<0.05). The difference between postoperative and preoperative Hb (△Hb1) was highest in group 1 (P<0.05). Conclusion For patients with valvular heart disease, intraoperative-only infusion of red blood cell suspension is associated with a better prognosis at discharge and during follow-up.

ObjectiveTo investigate the mechanism by which Jianpi Xiao'ai prescription (JPXAP) inhibits colorectal cancer progression by regulating the inducible nitric oxide synthase-arginase 1 (iNOS-ARG1) metabolic axis and inducing mitochondrial reactive oxygen species (mito-ROS)-mediated mitochondrial structural and functional impairment. MethodsAn arginine metabolism disorder model of human colorectal cancer HCT116 cells was established by combined treatment with recombinant human interferon-γ (IFN-γ, 10 μg·L-1) and N(ω)-hydroxy-L-arginine (Nor-NOHA, 200 μmol·L-1) for 24 h, followed by intervention with 5%, 10%, or 20% JPXAP-containing serum. Cell proliferation was assessed using cell counting kit-8 (CCK-8), 5-ethynyl-2′-deoxyuridine (EdU) staining, and colony formation assays. Cell invasion and migration were evaluated using Transwell chamber and wound healing assays. Mitochondrial membrane potential (MMP) and ROS levels were assessed by JC-1 and MitoSOX staining, respectively. Mitochondrial ultrastructure was observed by transmission electron microscopy (TEM). The expression of iNOS, ARG1, and mitochondrial dynamics-related proteins, including mitofusin 2 (MFN2) and dynamin-related protein 1 (DRP1), was analyzed by Western blot and immunofluorescence. The levels of L-arginine, citrulline, and urea were determined by colorimetric methods and enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the blank group, the model group exhibited significantly upregulated iNOS expression, downregulated ARG1 expression, a decreased ARG1/iNOS ratio, reduced L-arginine and urea levels, and increased citrulline levels (P<0.05). Meanwhile, mito-ROS accumulation was significantly increased, the JC-1 red/green fluorescence ratio was decreased, and mitochondria showed swelling and cristae disruption, indicating that metabolic disorder induced mitochondrial injury. Compared with the model group, all JPXAP-treated groups further decreased the ARG1/iNOS ratio, enhanced nitric oxide (NO) and reactive nitrogen species accumulation, further reduced L-arginine and urea levels, and increased citrulline levels (P<0.01). EdU-positive rate, colony formation rate, wound healing rate, and Transwell invasion number all decreased significantly with increasing serum concentration (P<0.01). Mito-ROS levels were further elevated, and the JC-1 red/green ratio further decreased. TEM revealed aggravated mitochondrial swelling and vacuolization. MFN2 expression was downregulated and DRP1 expression was upregulated (P<0.01),in a dose-dependent manner. ConclusionJPXAP further activates NO-mediated oxidative/nitrosative stress under arginine metabolism imbalance, inducing mito-ROS accumulation, MMP collapse, and mitochondrial dynamics imbalance, thereby inhibiting colorectal cancer cell proliferation and migration. These findings reveal an antitumor mechanism of JPXAP based on coordinated targeting of the "metabolism-mitochondria" axis.
