The Dunhuang manuscript Fuxing Jue takes the "Tangye Jingfa Tu" as the core of its theory on prescription and compatibility. Its medication principles mainly include the "five elements principle of tonifying and purging" and the "five elements principle of elimination and transformation". Based on the differentiation of deficiency and excess in the five Zang organs， it flexibly applies medicinal properties， usage， and flavor transformation for tonifying and purging， forming its unique method of medication and compatibility. In Taiyin disease， "fullness syndrome" often occurs together with "diarrhea"， and these two conditions also serve as the primary indications for the middle-regulating formulas. Among them， Lizhong Wan （Tang） mainly address Taiyin deficiency. The three Xiexin Tang （Banxia Xiexin Tang， Gancao Xiexin Tang， Shengjiang Xiexin Tang） address Taiyin deficiency accompanied by pathogenic excess. The Sini Tangand Tongmai Sini Tang primarily treat dysfunction of the liver， spleen， and kidney with impaired opening and closing of Taiyin， manifesting as diarrhea. The medicinal flavors of middle-regulating formulas are pungent， sweet， and bitter， acting directly on the spleen of Taiyin. The pungent flavor induces purging of the spleen， sweet flavor tonifies the spleen， and bitter flavor eliminates lumps. When the constituent medicinal units of middle-regulating formulas are unified， the ratio of pungent to sweet flavors reflects the tonic and purgative strength of the formula. In addition， the two decoction methods， "short-term decoction to extract Qi" and "long-term decoction to extract flavor"， also influence the formula's tonifying and purgative effects. Based on the composition of flavors and special decoction methods， this article discusses the differences in the use of middle-regulating formulas for treating "“fullness syndrome" versus "diarrhea". Dysfunction of the spleen can give rise to various diseases. Therefore， middle-regulating formulas are not limited to treating "deficiency， cold， and dampness" syndromes. Later generations of physicians further modified Lizhong Tang to treat "excess， heat， and dryness" syndromes， laying a solid foundation for more flexible and effective clinical application of middle-regulating formulas.

Objective To compare the induction effects of direct treatment with low-temperature plasma(LTP)and treatment with plasma-activated medium(PAM)on immunogenic cell death(ICD)of melanoma cells.Methods After direct treatment of melanoma cell line B16F10 with LTP and treatment of it with PAM for 24 hours,cell viability was detected by MTT assay.Flow cytometry was used to detect cell apoptosis and the expression of calreticulin(CRT)on the cell surface.The adenosine triphosphate(ATP)content in the culture medium was detected by an ATP detection kit.The content of high-mobility group box 1(HMGB1)in the cell culture medium was detected by ELISA.B16F10 cells treated with LTP were co-cultured with immature dendritic cells(DC)DC2.4 cell line,and flow cytometry was used to detect DC surface molecules CD80 and CD86.Results Compared with the control group,both direct treatment and indirect treatment could lead to a decrease in the viability of B16F10 cells,an increase in the apoptosis rate,an increase in intracellular ROS,an increase in CRT expression,and an increase in the secretion of ATP and HMGB1(P＜0.05).At the same treatment time,the expression of CRT and the release of ATP in B16F10 cells directly treated with LTP were higher than those indirectly treated with PAM(P＜0.05).Compared with the DC2.4 group,the expression proportion of the DC cell maturation marker molecule CD80 was significantly increased in LTP-120s group,LTP-180s group,PAM-120s group,and PAM-180s group.The expression proportion of the DC cell maturation marker molecule CD86 was significantly increased in LTP-120s group,LTP-180s group,and PAM-180s group,and the difference was statistically significant(P＜0.05).Conclusion Both direct treatment with LTP and indirect treatment with PAM can induce ICD in melanoma cells.The direct treatment with LTP has a better induction effect.

Objective: To evaluate the safety and efficacy of therapeutic whole blood exchange combined with lymphoplasmapheresis in the treatment of refractory autoimmune hemolytic anemia (AIHA). Methods: A retrospective analysis was performed on the clinical data of AIHA patients who underwent therapeutic whole blood exchange combined with lymphoplasmapheresis at our hospital from March 2022 to May 2025. Efficacy was assessed by comparing changes in hemoglobin, platelet count, and bilirubin levels before and after treatment. Safety was evaluated by analyzing vital signs before and after the procedure, parameters during the exchange, and adverse reactions. Results: A total of 12 AIHA patients were enrolled, completing 19 exchange procedures. The number of procedures per patient ranged from 1 to 3. The median treatment duration was 67 (65-73) minutes, with a median exchange volume of 2 025 (1 851-2 121) mL, comprising 4.5 (4-6) units of red blood cells and 1 350 (1 200-1 400) mL of plasma. Ten patients achieved partial remission, one achieved complete remission, and one showed no response, yielding an response rate of 91% (11/12). After a single session, hemoglobin increased significantly by 17.58±9.85 g/L (P<0.01), while platelets counts decreased by 45 (17.5, 79)×10 /L (P<0.05), and both systolic and diastolic blood pressure showed a significant elevation (P<0.05). However, no statistically significant differences were observed in total bilirubin, indirect bilirubin, white blood cell count, or heart rate. During the procedures, 4 adverse reactions occurred in 3 patients: one child experienced severe heart rate fluctuation twice consecutively, and two adults developed plasma allergies. All reactions resolved spontaneously without pharmacological intervention. Conclusion: The combination of therapeutic whole blood exchange and lymphoplasmapheresis appears to be a safe and effective treatment for refractory AIHA patients.

Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Identifying drug-drug interactions(DDIs)is essential to prevent adverse effects from polypharmacy.Although deep learning has advanced DDI identification,the gap between powerful models and their lack of clinical application and evaluation has hindered clinical benefits.Here,we developed a Multi-Dimensional Feature Fusion model named MDFF,which integrates one-dimensional simplified molec-ular input line entry system sequence features,two-dimensional molecular graph features,and three-dimensional geometric features to enhance drug representations for predicting DDIs.MDFF was trained and validated on two DDI datasets,evaluated across three distinct scenarios,and compared with advanced DDI prediction models using accuracy,precision,recall,area under the curve,and F1 score metrics.MDFF achieved state-of-the-art performance across all metrics.Ablation experiments showed that integrating multi-dimensional drug features yielded the best results.More importantly,we obtained adverse drug reaction reports uploaded by Xiangya Hospital of Central South University from 2021 to 2023 and used MDFF to identify potential adverse DDIs.Among 12 real-world adverse drug reaction reports,the predictions of 9 reports were supported by relevant evidence.Additionally,MDFF demon-strated the ability to explain adverse DDI mechanisms,providing insights into the mechanisms behind one specific report and highlighting its potential to assist practitioners in improving medical practice.

OBJECTIVES: Wild-caught Microtus fortis (M. fortis) at the age of 9-15 months can develop epithelial ovarian cancers similar to human epithelial ovarian cancers under natural conditions during experimental animal breeding, but its pathological types and biological characteristics remain unclear. This study aims to analyze the biological characteristics of spontaneous ovarian cancer in M. fortis, intending to develop M. fortis as an animal model for human epithelial ovarian cancer. METHODS: The female M. fortis (9-15 months old) with spontaneous ovarian cancer were selected as the experimental group, and healthy M. fortis from the same litter were selected as the control group. The ovarian pathological changes of the two groups were observed by dissection. Blood routine and biochemical indicators were measured by biochemical analysis. Hematoxylin and eosin (HE) staining was performed to observe the pathological changes in the ovarian cancer tissue of M. fortis. Immunohistochemical staining was used to detect the protein expression of common ovarian cancer markers, and real-time RT-PCR was used to analyze the transcription levels of ovarian cancer-related genes. RESULTS: Spontaneous ovarian cancer in M. fortis mainly affects both ovaries, with tumors appearing solid or cystic. HE staining and histopathological analysis confirmed that the ovarian tumors originated from ovarian surface epithelium. Compared to the control group, the experimental group showed significantly decreased hemoglobin (P<0.01), hematocrit (P<0.05), albumin (P<0.05), and blood glucose levels (P<0.01), while lymphocyte percentage (P<0.05), monocyte percentage (P<0.05), cholesterol (P<0.01), and progesterone (P<0.01) levels were significantly increased. Expression of ovarian cancer-related genes, including ID3, CDC42, RHOA, RB1CC1, NF1, PIN1, MIB1, PDS5A, MCM7, and MLH1, was significantly downregulated (all P<0.05), while PAX8 gene expression was significantly upregulated (P<0.05). Immunohistochemical results showed that Wilms' tumor gene 1 (WT1) protein was mainly distributed throughout the cell, with significantly higher expression in ovarian cancer M. fortis. Tumor protein 53 (TP53) was expressed in both healthy and ovarian cancer M. fortis and was distributed throughout the cell. Hepatocyte nuclear factor 1 beta (HNF1B) and progesterone receptor (PR) protein were highly expressed in the ovarian tissue of healthy M. fortis but were significantly reduced in the ovarian cancer M. fortis, though both were located in the cytoplasm. CONCLUSIONS Spontaneous ovarian cancer in M. fortis is serous ovarian cancer. Compared to healthy M. fortis, significant differences were observed in ovarian tissue morphology, biochemical indicators, ovarian cancer-related gene expression, and protein expression, which show similarity to the biological characteristics of human serous ovarian cancer. This suggests that M. fortis could be an ideal animal model for studying human serous ovarian cancer.

OBJECTIVES: To explore the mechanism of cinnamic acid (CA) for improving doxorubicin-induced myocardial injury (DIC) in mice. METHODS: Network pharmacology analysis was used to obtain the key targets of CA and DIC. Male C57BL/6J mice were randomized into Sham, DOX, CA (25, 50 and 100 mg/kg)+DOX, and CA+Ferrostatin-1+DOX groups, and their myocardial function and pathology were examined by echocardiography and HE staining. Serum levels of CK-MB, LDH, MDA, IL-6, TNF‑α and myocardial ROS level were detected, and the expression levels of TLR4 and ferroptosis pathway proteins in myocardial tissue were detected by Western blotting. Cultured murine cardiomyocytes (HL-1 cells) with or without transfection with a small interfering RNA targeting TLR4 (si-TLR4) were treated with DOX or Erastin, and the cellular ROS content was measured by DCFH-DA staining; the expression level of GPX4 was detected using immunofluorescence staining. RESULTS: Network pharmacology analysis suggested that CA may improve DIC through TLR4 signaling. DOX treatment caused obvious myocardial injury in mice, which showed significantly increased serum levels of CK-MB, LDH, MDA, IL-6, TNF-α and myocardial ROS level with decreased myocardial levels of SLC7A11 and GPX4 proteins and increased levels of TLR4 and PTGS2 proteins. All these changes in the mouse models were significantly alleviated by treatment with CA, and the mice receiving CA or ferrostatin-1 treatment exhibited increased myocardial expressions of SLC7A11 and GPX4 proteins and lowered expressions of TLR4 and PTGS2 proteins. In cultured HL-1 cells, treatment with DOX and Erastin both obviously increased intracellular ROS level and decreased cellular GPX4 expression level, and these changes were strongly attenuated by TLR4 interference. CONCLUSIONS CA, as a potent herbal monomer, can effectively alleviate DIC in mice by inhibiting TLR4-mediated ferroptosis.

Although deep learning has advanced DDI identification, the gap between powerful models and their lack of clinical application and evaluation has hindered clinical benefits. Here, we developed a Multi-Dimensional Feature Fusion model named MDFF, which integrates one-dimensional simplified molecular input line entry system sequence features, two-dimensional molecular graph features, and three-dimensional geometric features to enhance drug representations for predicting DDIs. MDFF was trained and validated on two DDI datasets, evaluated across three distinct scenarios, and compared with advanced DDI prediction models using accuracy, precision, recall, area under the curve, and F1 score metrics. MDFF achieved state-of-the-art performance across all metrics. Ablation experiments showed that integrating multi-dimensional drug features yielded the best results. More importantly, we obtained adverse drug reaction reports uploaded by Xiangya Hospital of Central South University from 2021 to 2023 and used MDFF to identify potential adverse DDIs. Among 12 real-world adverse drug reaction reports, the predictions of 9 reports were supported by relevant evidence. Additionally, MDFF demonstrated the ability to explain adverse DDI mechanisms, providing insights into the mechanisms behind one specific report and highlighting its potential to assist practitioners in improving medical practice.
