Abstract Modern western medicine typically focuses on treating specific symptoms or diseases, and traditional Chinese medicine (TCM) emphasizes the interconnections of the body’s various systems under external environment and takes a holistic approach to preventing and treating diseases. Phenomics was initially introduced to the field of TCM in 2008 as a new discipline that studies the laws of integrated and dynamic changes of human clinical phenomes under the scope of the theories and practices of TCM based on phenomics. While TCM Phenomics 1.0 has initially established a clinical phenomic system centered on Zhenghou (a TCM definition of clinical phenome), bottlenecks remain in data standardization, mechanistic interpretation, and precision intervention. Here, we systematically elaborates on the theoretical foundations, technical pathways, and future challenges of integrating digital medicine with TCM phenomics under the framework of “TCM phenomics 2.0”, which is supported by digital medicine technologies such as artificial intelligence, wearable devices, medical digital twins, and multi-omics integration. This framework aims to construct a closed-loop system of “Zhenghou–Phenome–Mechanism–Intervention” and to enable the digitization, standardization, and precision of disease diagnosis and treatment. The integration of digital medicine and TCM phenomics not only promotes the modernization and scientific transformation of TCM theory and practice but also offers new paradigms for precision medicine. In practice, digital tools facilitate multi-source clinical data acquisition and standardization, while AI and big data algorithms help reveal the correlations between clinical Zhenghou phenomes and molecular mechanisms, thereby improving scientific rigor in diagnosis, efficacy evaluation, and personalized intervention. Nevertheless, challenges persist, including data quality and standardization issues, shortage of interdisciplinary talents, and insufficiency of ethical and legal regulations. Future development requires establishing national data-sharing platforms, strengthening international collaboration, fostering interdisciplinary professionals, and improving ethical and legal frameworks. Ultimately, this approach seeks to build a new disease identification and classification system centered on phenomes and to achieve the inheritance, innovation, and modernization of TCM diagnostic and therapeutic patterns.

Under the background of increasingly severe drug-resistant bacteria infections,protracted course of chronic wounds has become clinical difficulties disturbing both patients and doctors.With the unique advantages of broad antibacterial spectrum,low drug resistance rate and high safety,polyhexanide antibacterial agent has gradu-ally become a major approach for treatment and nursing of chronic wounds.The application of polyhexamethylene biguanide(PHMB)antimicrobial agents in treatment and nursing of chronic wounds was reviewed in the article,including the antibacterial properties,comparisons with other antimicrobial agents,actual clinical practice and potential side effects,aiming to guide the further application of PHMB antimicrobial agents in treatment of chronic wounds.

In order to understand the infection status of Escherichia coli(E.coli)in different popu-lations of chickens,E.coli was isolated and identified from 1-day-old chickens,dead embryos,clini-cal dead chickens from 3 hatcheries and 9 broiler farms in Yantai area,and 1 950 samples from e-liminated breeder chickens;the homology of the isolated strains was analyzed by pulsed field gel e-lectrophoresis;virulence genes and serotypes were identified by PCR;pathogenicity was determined by challenge chicken embryos.Drug resistance of the strain was determined by drug sensitivity test.Results showed that a total of 116 strains of E.coli were isolated,of which 97 strains were successfully classified into 66 band types,15 virulence genes and 5 serotype were detected by PCR,and 56,32 and 28 strains were divided into high,medium and low pathogenic strains by chicken embryo challenge test.Results indicated that E.coli from clinically dead chickens and eliminated breeder chickens had higher pathogenicity and drug resistance.This study provides a reference ba-sis for the prevention and control of colibacillosis in chicken farms.

Red cell alloimmunization represents the primary cause of hemolytic disease of the fetus and newborn (HDFN). With advancing clinical management of ABO and Rh alloimmunization, non-Rh alloimmunization has garnered increasing attention. Although MNS system alloimmunization remains rare, reported cases have gradually increased in recent years, particularly in East Asia. Current clinical practice still lacks standardized management protocols for MNS alloimmunization, especially HDFN caused by IgG anti-M antibodies. This review synthesizes recent global research advances in anti-M-mediated HDFN, particularly fetal hemolytic disease, summarizing the unique characteristics of anti-M alloimmunization to inform clinical management strategies for MNS system incompatibility.

Objective:To screen broadly neutralizing antibodies in human immunodeficiency virus-1（HIV-1）chronically infected individuals and characterize their molecular features and to provide new strategies for rational vaccine development and antibody-based therapeutics.Methods:A total of 34 treatment-na?ve individuals with chronic HIV-1 infection were enrolled. Plasma antibody binding levels were measured against two HIV-1 envelope proteins. Single antigen-specific memory B cells were sorted from high-binding samples，and antibody variable region genes were amplified by PCR for paired expression. The monoclonal antibodies were evaluated for neutralizing activity using pseudovirus assays，and their structural features were analyzed by integrating AlphaFold 3 prediction with Discovery Studio molecular docking.Results:Plasma samples showed strong binding to DU422-GP140 and BG505-GP140. Eight monoclonal antibodies were isolated from two donors. Among them，antibodies 0919-A4，0919-A9 and 0808-A2 could cross-react with GP140 from HIV-1 subtypes AE，BC and B. The monoclonal antibody 0919-A9 demonstrated potent neutralizing activity against SF162（Tier 1）and CH181（Tier 2）pseudoviruses，with somatic hypermutation rates of 13.27%（heavy chain）and 15.58%（light chain）. Structural modeling revealed its specific targeting of the V1V2 region on GP120.Conclusion:The isolated antibody 0919-A9 effectively neutralizes Tier 2 pseudoviruses. Its high somatic mutation frequency and V1V2-targeting property underlie its neutralizing activity，providing both a promising candidate and mechanistic insights for HIV vaccine development and antibody-based therapeutic strategies.

Objective To investigate the effect of programmed death ligand-1(PD-L1)overexpression on epithelial mesenchymal transformation(EMT)in endometrial cancer cells and its possible mechanism.Methods Ishikawa/PD-L1,a PD-L1 stable overexpression cell line constructed in the laboratory and the control Ishikawa/EV were used.The efficiency of PD-L1 overexpression was detected by qPCR and Western blot assay.The cell migration ability and invasion activity were detected by scratch assay and Transwell assay.The EMT-related protein and the phosphorylation level of nuclear transcription factor-κB(NF-κB)were detected by Western blot.Results Compared with the control group,the migration ability and invasion activity of Ishikawa/PD-L1 were significantly enhanced,and the expression of E-cadherin was significantly down-regulated,whereas vimentin,N-cadherin and p-p65 were significantly increased.Conclusion PD-L1 can promote EMT by inducing the activation of NF-κB pathway,and thus enhance the migration and invasion ability of endometrial cancer cells.
