BACKGROUND:Steroid-induced femoral head necrosis is mostly caused by long-term and extensive use of hormones,but its specific pathogenesis is not yet clear and needs further study. OBJECTIVE:To screen out the differential miRNAs in osteoclast exosomes after the intervention of Panax notoginseng saponins,and on this basis,to further construct an osteogenic-related ferroptosis regulatory network to explore the potential mechanism and research direction of steroid-induced osteonecrosis of the femoral head. METHODS:MTT assay was used to detect the toxic effects of different concentrations of dexamethasone and different mass concentrations of Panax notoginseng saponins on Raw264.7 cell line.Tartrate resistant acid phosphatase staining and TUNEL assay were used to detect the effects of Panax notoginseng saponins on osteoclast inhibition and apoptosis.Exosomes were extracted from cultured osteoclasts with Panax notoginseng saponins intervention.Exosomes from different groups were sequenced to identify differentially expressed miRNAs.CytoScape 3.9.1 was used to construct and visualize the regulatory network between differentially expressed miRNAs and mRNAs.Candidate mRNAs were screened by GO analysis and KEGG analysis.Finally,the differential genes related to ferroptosis were screened out,and the regulatory network of ferroptosis-related genes was constructed. RESULTS AND CONCLUSION:(1)The concentration of dexamethasone(0.1 μmol/L)and Panax notoginseng saponins(1 736.85 μg/mL)suitable for intervention of Raw264.7 cells was determined by MTT assay.(2)Panax notoginseng saponins had an inhibitory effect on osteoclasts and could promote their apoptosis.(3)Totally 20 differentially expressed miRNAs were identified from osteoclast-derived exosome samples,and 11 differentially expressed miRNAs related to osteogenesis were predicted by target mRNAs.The regulatory networks of 4 up-regulated differentially expressed miRNAs corresponding to 155 down-regulated candidate mRNAs and 7 down-regulated differentially expressed miRNAs corresponding to 238 up-regulated candidate mRNAs were constructed.(4)Twenty-four genes related to ferroptosis were screened out from the differential genes.Finally,12 networks were constructed(miR-98-5p/PTGS2,miR-23b-3p/PTGS2,miR-425-5p/TFRC,miR-133a-3p/TFRC,miR-185-5p/TFRC,miR-23b-3p/NFE2L2,miR-23b-3p/LAMP2,miR-98-5p/LAMP2,miR-182-5p/LAMP2,miR-182-5p/TLR4,miR-23b-3p/ZFP36,and miR-182-5p/ZFP36).These results indicate that Panax notoginseng saponins may regulate osteoblast ferroptosis by regulating the expression of miRNAs derived from osteoclast exosomes,thus providing a new idea for the study of the mechanism of steroid-induced femoral head necrosis.

ObjectiveThis study aims to develop a prediction model for the compatibility of Chinese medicinal pairs based on Graph Convolutional Networks （GCN）， named HC-GCN. The model integrates the properties of herbs with modern pharmacological mechanisms to predict pairs with specific therapeutic effects. It serves as a demonstration by applying the model to predict and validate the efficacy of blood-activating herb pairs. MethodsThe training dataset for herb pair prediction was constructed by systematically collecting commonly used herb pairs along with their characteristic data， including Qi， flavor， meridian tropism， and target genes. Integrating traditional characteristics of herb with modern bioinformatics， we developed an efficacy-oriented herb pair compatibility prediction model （HC-GCN） using graph convolutional networks （GCN）. This model leverages machine learning to capture the complex relationships in herb pair compatibility， weighted by efficacy features. The performance of the HC-GCN model was evaluated using accuracy （ACC）， recall， precision， F1 score （F1）， and area under the ROC curve （AUC）. Its predictive effectiveness was then compared to five other machine learning models： eXtreme Gradient Boosting （XGBoost）， logistic regression （LR）， Naive Bayes， K-nearest neighbor （KNN）， and support vector machine （SVM）. ResultsUsing herb pairs with blood-activating effects as a demonstration， a prediction model was constructed based on a foundational dataset of 46 blood-activating herb pairs， incorporating their Qi， flavor， meridian tropism， and target gene characteristics. The HC-GCN model outperforms other commonly used machine learning models in key performance metrics， including ACC， recall， precision， F1 score， and AUC. Through the predictive analysis of the HC-GCN model， 60 herb pairs with blood-activating effects were successfully identified. Among of these potential herb pairs， 44 include at least one herb with blood-activating effects. ConclusionIn this study， we established an efficacy-oriented compatibility prediction model for herb pairs based on GCN by integrating the unique characteristics of traditional herbs with modern pharmacological mechanisms. This model demonstrated high predictive performance， offering a novel approach for the intelligent screening and optimization of traditional Chinese medicine prescriptions， as well as their clinical applications.

Systemic lupus erythematosus (SLE) is a highly heterogeneous systemic autoimmune disease characterized by multi-organ involvement, recurrent flares, and chronic progression. With advances in diagnostics and therapeutics, SLE management is shifting from disease control toward long-term remission and organ protection. Incorporating recent global evidence and characteristics of the Chinese population, the National Clinical Research Center for Dermatologic and Immunologic Diseases and the Chinese SLE Treatment and Research Group (CSTAR) have developed the Chinese guidelines for the diagnosis and treatment of systemic lupus erythematosus (2025 edition). Centered on a treat-to-target strategy, the guidelines prioritize clinical remission and low disease activity as primary goals, optimizing the use of glucocorticoids, immunosuppressants, biologics, and novel therapies. Key updates include individualized management recommendations for lupus nephritis, multi-organ involvement, and antiphospholipid syndrome, alongside first-ever evidence-based recommendations on vaccination in SLE patients. By integrating large-scale domestic cohort studies and real-world data, this edition provides more precise and actionable guidance, offering significant value for standardizing and improving SLE diagnosis, treatment, and long-term management in China.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To evaluate the effectiveness of surgical methods for correcting pollybeak deformity in Chinese rhinoplasty.Methods:A retrospective chart review was conducted for patients who underwent pollybeak correction between January 2021 and December 2022 at the Department of Plastic and Aesthetic (Burn) Surgery, the Second Xiangya Hospital of Central South University. Individualized correction was tailored based on the etiology and severity of the nasal deformity of each patient, involving techniques such as resection of the anterior part of the nasal septum, reconstruction of nasal tip support, reconstruction of the middle part of the nasal vault, and excision of skin in the upper region of the nasal tip. A modified classification system for pollybeak deformity, the supratip fullness rating scale (SFRS), was developed to evaluate supratip fullness (0-3 points, with higher scores indicating more apparent deformity). The patients aesthetic outcomes were assessed by surgeons using the visual analogue scale (VAS) (0-10 points, with higher scores indicating more apparent deformity), and patient self-assessed using the rhinoplasty outcome evaluation (ROE) questionnaire (0-100 points, with higher scores indicating higher satisfaction). The measurement data of normal distribution was expressed as Mean±SD and analyzed by paired t-test; the measurement data of non-normal distribution was expressed as M( Q1, Q3) and analyzed by Wilcoxon signed rank test. Results:In a cohort study of 53 rhinoplasty patients (7 male, 46 female; age range 19-45 years, mean 29 years), comprising 15 primary and 38 secondary surgeries, nasal tip deformities were evaluated. Deformities were classified as mild (5 cases), moderate (25 cases), and severe (23 cases). Over a follow-up period of 6-17 months (mean 9.5 months), significant aesthetic improvements in the nasal tip region were observed. The SFRS scores decreased from 2(2, 3) preoperatively to 0(0, 0) postoperatively ( Z = -6.58, P < 0.001), and VAS scores decreased from 7.47±1.73 to 1.79±1.67 ( t = -25.61, P < 0.001). High patient satisfaction was indicated by a mean ROE score of 82.45±11.55. No significant complications, such as nasal tip ptosis, skin necrosis, or scar hyperplasia, were reported. Conclusion:Selecting an appropriate surgical method based on the severity and cause of pollybeak deformity can achieve satisfactory outcomes. Post-operative patients exhibit significant aesthetic improvement in the upper nasal tip area, resulting in high patient satisfaction.

Objective:To investigate the surgical effect of pedicled upper lip mucosal flap in repairing nasal septal mucosal defects after rhinoplasty.Methods:A retrospective analysis was performed from January 2016 to October 2022, the clinical data of patients with nasal septal mucosal defects after rhinoplasty were collected in the Department of Plastic and Aesthetic (Burn) Surgery at the Second Xiangya Hospital of Central South University. The pedicled upper lip mucosal flap was utilized for repair based on the patient’s medical history and wound condition. The pedicle of the flap was designed 1 cm adjacent to the frenulum of the upper lip, and an appropriate flap was incised based on the size of the wound, with dissection performed up to the superficial layer of the orbicularis oris muscle. The dissection establishes an upper lip tunnel that connects the gingival-buccal groove to the nasal cavity. The pedicled upper lip mucosal flap was elevated and transposed into the nasal cavity via the upper lip tunnel. The position of the flap was adjusted to ensure complete coverage and fixation of the nasal septal defect wound using 5-0 absorbable suture. The visual analogue scale (VAS) and the nasal obstruction symptom evaluation (NOSE) scale were utilized to facilitate patients’ satisfaction evaluation and assessment of nasal obstruction symptoms before surgery and at 6 months post-surgery. The VAS total score was 10 points, with higher scores indicating greater levels of patient satisfaction. The NOSE scale comprises of 5 items, each assigned a score ranging from 0 to 4, denoting absence of symptoms, very mild presence, moderate intensity, relatively severe manifestation, and highly severe indication respectively. The measurement data of VAS and NOSE scores before surgery and at 6 months post-surgery was expressed by Mean±SD, using paired t-test. The score distribution of the NOSE scale was represented by the number of cases, using Mann-Whitney U test. Results:The study included a total of 15 female patients, with an average age of (27.6±2.9) years (ranging from 23 to 33 years). Eleven cases presented with preoperative cartilage exposure, and the size of tissue defect ranged from 0.9 cm×0.5 cm to 1.5 cm×0.7 cm. Nine patients had a history of smoking. Skin grafting was performed in 9 patients, while nasal mucosal metastasis was observed in 8 patients. The dimensions of the flap varied from 4.0 cm×1.2 cm to 7.0 cm×1.5 cm. The postoperative recovery was satisfactory, with successful survival of the skin flaps and no occurrences of infection, hematoma, wound dehiscence, or flap necrosis. The average duration of follow-up was (8.2±2.1) months (ranging from 6 to 12 months). The postoperative VAS score (7.73±0.88) was significantly higher compared to the preoperative score (1.86±0.74) ( P<0.01). Additionally, the postoperative NOSE score (4.66±1.71) showed a significant decrease from the preoperative score (10.73±2.68), with a statistically significant difference ( P<0.01). Among them, after surgery items of stuffy or unbreathable nose (2 cases vs. 15 cases), nasal obstruction (1 case vs. 14 cases), and feeling that the nose was not enough to breathe during exercise or exertion (4 cases vs. 14 cases) scored≥2 points were significantly less than those before operation (all P<0.01). Conclusion:The utilization of pedicled upper lip mucosal flap in the reconstruction of severe nasal septal mucosal defects following rhinoplasty has proven to be highly effective. The postoperative satisfaction of patients is remarkably high, the ventilation function exhibits significant improvement, and no severe complications are observed.
