ObjectiveTo analyze the pharmacodynamic substance basis of Shangkeling Spray and its potential mechanisms in intervening knee osteoarthritis （KOA） using ultra-performance liquid chromatography-tandem mass spectrometry （UPLC-MS）， network pharmacology， and molecular docking technology. MethodsUPLC-MS was used to identify the chemical components of Shangkeling Spray. Pharmacokinetic properties were employed to screen potential active ingredients. Network pharmacology methods were utilized to collect potential targets of these ingredients and the pathological gene set of KOA. An "active ingredient-disease" target network was constructed using databases such as STRING. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） functional enrichment analyses were performed using clusterProfiler. Libraries including NumPy were employed to calculate shortest path lengths to identify dominant pharmacodynamic links. Core gene clusters were identified using MCODE， validated through the Gene Expression Omnibus （GEO） database， and molecular docking was performed between key active ingredients and core targets. ResultsA total of 322 and 314 chemical components were identified under positive and negative ion modes， respectively， with 410 components in total after de-duplication， mainly including flavonoids， coumarins， terpenoids， organic acids， and alkaloids. Analysis of the "active ingredient-disease" network identified "development and regeneration"， "cell growth and death"， "immune system"， and "nervous system" as the dominant pharmacodynamic links of Shangkeling Spray in the treatment of KOA. Molecular docking showed that key active ingredients， such as bletillin A， formononetin， morin， oxymatrine， aconitine， gallic acid， curdione， apigenin， naringenin， and oleanolic acid， tightly bound to functional domains of 10 key targets including Jun proteins（JUN）， interleukin-6 （IL-6）， protein kinase B1 （Akt1）， Caspase-3， nuclear transcription factor-κB subunit p65（RELA）， nuclear factor-kappaB1（NF-κB1）， Cyclin D₁， mammalian target of rapamycin（mTOR）， tumor necrosis factor （TNF）， and Fos proto-oncogene protein （FOS）. These interactions synergistically regulated the phosphatidylinositol 3-kinase （PI3K）/Akt/mTOR-related signaling axis and nervous system-related pathways， mediating cartilage repair， reducing inflammation and pain， and improving KOA. ConclusionThis study preliminarily clarifies the pharmacodynamic substance basis of Shangkeling Spray and suggests that its main active ingredients may improve KOA by synergistically regulating the PI3K/Akt/mTOR-related pathways， providing a reference for subsequent exploration of its substance benchmark and mechanism of action.

By tracing back to the classical literature of traditional Chinese medicine （TCM）， this paper proposes a TCM philosophy integrating "dao （道）-shen（神）-formula" as a unified whole. It systematically elaborates the formula-constructing thought that "the monarch drug follows dao， and the formula carries dao"， analyzes shen （spirit/ life vitality） from the perspectives of its substance， manifestation and function， and explains the pivotal role of shen in connecting dao and formula. Taking Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》） as an example， the paper explores how the "dao-shen-formula" union is implemented in classics. Based on the Inner Canon of Yellow Emperor （《黄帝内经》）， the paper articulates a practical pathway for the "dao-shen-formula" union， namely "observing shen to differentiate the mechanism → restoring dao to regulate shen → achieving harmony of shen and restoration of dao"， thereby transforming abstract concepts into operable and verifiable practical approaches. It is hoped that this study will provide theoretical foundation and practical guidance for the shift from treating diseases to treating the person， and from correcting deviations to restoring dao in TCM.

Methods: Cervical radiographs were analyzed. EOP hyperplasia was classified into three subtypes with standardized length measurements. Variables encompassed demographics, ONL-related indices, and sagittal parameters. Subtype comparisons and multivariate regression analyses (with EOP length as dependent variable) were conducted. Results: Analysis of 187 CSM patients (64.2% male) identified gender-specific patterns: males exhibited greater EOP length (9.4±6.8 mm vs. 4.6±3.4 mm, p<0.001). Type III EOP demonstrated male predominance (82.4% vs. type I 31.8%, type II 51.4%; p<0.001), with associated longer hyperplasia length (11.6±6.6 mm vs. type II 5.1±1.9 mm, p<0.001). Type III EOP was associated with higher ONL prevalence (type III 64.8% vs. type I 45.5%, type II 41.9%; p=0.010) and longer ONL osteophyte length (type III 18.8±9.8 mm vs. type I 14.2±8.1 mm, type II 14.2±9.4 mm; p=0.046). Multivariate regression confirmed male sex (β=–3.82, p=0.009), ONL osteophyte length (β=0.16, p=0.017), T1 slope (β=0.27, p=0.041), and spino-cranial angle (β=–0.19, p=0.009) as factors independently associated with EOP length (adjusted R²=0.382). Conclusions Severe EOP hyperplasia exhibits a male-predominant distribution pattern and demonstrates significant radiological associations with ONL and cervical sagittal imbalance in CSM patients. These findings advocate for EOP evaluation in clinical evaluations to identify high-risk biomechanical profiles.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated death globally. Liver transplantation (LT) has emerged as a key treatment for patients with HCC, and the Milan criteria have been adopted as the cornerstone of the selection policy. To allow more patients to benefit from LT, a number of expanded criteria have been proposed, many of which use radiologic morphological characteristics with larger and more tumors as surrogates to predict outcomes. Other groups developed indices incorporating biological variables and dynamic markers of response to locoregional treatment. These expanded selection criteria achieved satisfactory results with limited liver supplies. In addition, a number of prognostic models have been developed using clinicopathological characteristics, imaging radiomics features, genetic data, and advanced techniques such as artificial intelligence. These models could improve prognostic estimation, establish surveillance strategies, and bolster long-term outcomes in patients with HCC. In this study, we reviewed the latest findings and achievements regarding the selection criteria and post-transplant prognostic models for LT in patients with HCC.

Persistent atrial fibrillation and other factors can cause mitral and tricuspid annular dilation and leaflet regurgitation,leading to severe functional mitral and tricuspid regurgitation.Patients often experience significant heart failure symptoms and poor prognosis.For patients with severe mitral or tricuspid regurgitation who are at high risk or contraindicated for surgical procedures,transbronchial repair(TEER)is an important alternative therapy that can effectively reduce valve regurgitation and improve cardiac function;Although there is a lack of large-scale data on atrial functional reflux,existing experience still shows that TEER can significantly reduce reflux and improve patients'quality of life.However,double valve intervention therapy poses challenges,especially when combined with TEER repair,which is technically more complex,time-consuming,and carries higher risks.Foreign data shows that simultaneous or staged double valve intervention can safely improve cardiac function and increase survival rates,but the optimal intervention strategy still needs further research.Due to the fact that tricuspid TEER devices have not yet been launched in China,only staged treatment can be adopted at present.This case report shows a patient with severe atrial functional mitral and tricuspid regurgitation who underwent staged transcatheter edge to edge repair surgery successfully.During a 1-year follow-up,bilateral valve regurgitation continued to improve,indicating that staged repair of bilateral atrioventricular valve regurgitation through the catheter margin is a feasible and effective treatment option.

OBJECTIVE T o explore the prevention and control measures for the hospital-acquired pulmonary mu-cormycosis caused by Cunninghamella bertholletiae.METHODS One case of patient with pulmonary mucormyco-sis caused by Cunninghamella bertholletiae who was treated in pediatric intensive care unit(PICU)of a three-A general hospital was enrolled in the study,the process of clinical diagnosis and treatment was summarized.A ret-rospective survey regarding four aspects including people,machine,materials and environment was conducted.The related factors leading to the hospital-acquired infections in the patient were analyzed.RESULTS The child was diagnosed with severe aplastic anemia and underwent hematopoietic stem cell transplantation,the child was treated with various invasive procedures during the treatment period and was infected with pulmona-ry mucormycosis caused by the rare Cunninghamella bertholletiae.The occurrence of the pulmonary mucormyco-sis was associated with the poor management of medical textile,insufficient environmental cleaning and disinfec-tion and nonstandard invasive procedures.CONCLUSIONS The Cunninghamella bertholletiae infection is less com-mon,but the risk of death is high.It is necessary for the medical institutions to complete the prevention and con-trol measures and intensify the health care workers'capabilities in identification of the pathogenic fungus so as to reduce the incidence of pulmonary mucormycosis caused by the pathogen.
