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.

OBJECTIVE: To observe the effect of perioperative transcutaneous electrical acupoint stimulation (TEAS) on postoperative fatigue syndrome (POFS) in elderly patients undergoing laparoscopic radical gastrectomy. METHODS: A total of 80 elderly patients scheduled for laparoscopic radical gastrectomy were randomized into a TEAS group and a sham TEAS group, 40 cases in each one. In the TEAS group, TEAS intervention was applied at bilateral Hegu (LI4), Neiguan (PC6), Zusanli (ST36) and Sanyinjiao (SP6) from 30 min before anesthesia induction until surgery completion, and at 18:00 on 1st, 2nd and 3rd days after surgery, once a day, 30 min a time. In the sham TEAS group, the same acupoints were selected and connected to the electroacupuncture device at the same time, without electrical stimulation. One day before surgery and 1, 3, 7 days after surgery, the 10-item short form of identity consequence fatigue scale (ICFS-10) score was observed, and the POFS incidence rate of 1, 3, 7 days after surgery was assessed in the two groups. One day before surgery, surgery completion, and 1, 3 days after surgery, the serum levels of superoxide dismutase (SOD), β-endorphin (β-EP) were detected; 1 day before surgery and 1, 3, 7 days after surgery, the serum level of tumor necrosis factor-α (TNF-α) was detected in the two groups. The pain visual analog scale (VAS) score was observed at 24, 48 and 72 h after surgery; the intraoperative dosage of propofol and remifentanil, and the incidence rate of postoperative nausea and vomiting, itching, respiratory depression were recorded in the two groups. RESULTS: In the TEAS group, on 1, 3, 7 days after surgery, except for the scores of item 8-10, the item scores and the total scores of ICFS-10 were lower than those in the sham TEAS group (P<0.001); on 3 and 7 days after surgery, the POFS incidence rates were lower than those in the sham TEAS group (P<0.05). In the TEAS group, on 1 and 3 days after surgery, the serum levels of SOD were higher than those in the sham TEAS group (P<0.05, P<0.01); at surgery completion, and on 1, 3 days after surgery, the serum levels of β-EP were higher than those in the sham TEAS group (P<0.001, P<0.01); on 1, 3, 7 days after surgery, the serum levels of TNF-α were lower than those in the sham TEAS group (P<0.01, P<0.001). In the TEAS group, at 24, 48 and 72 h after surgery, the pain VAS scores were lower than those in the sham TEAS group (P<0.001, P<0.01, P<0.05); the intraoperative dosage of remifentanil was lower than that in the sham TEAS group (P<0.001); the incidence rate of postoperative nausea and vomiting was lower than that in the sham TEAS group (P<0.01). CONCLUSION Perioperative TEAS intervention can effectively reduce the incidence rate of POFS, improve fatigue symptom and mental state in elderly patients undergoing laparoscopic radical gastrectomy, its mechanism may related to enhancing endogenous β-EP release, inhibiting inflammatory response, and reducing central oxidative stress, thereby promoting postoperative recovery.

Objective To construct a fuzzy comprehensive evaluation model based on the analytic hierarchy process(AHP)to evaluate the quality of hemodialysis machines.Methods Firstly,the influencing factors for the quality of hemodialysis machines were determined with considerations on the requirements for medical technology assessment of medical devices and the hospital's many years of experience in use,maintenance and management of hemodialysis machines,and the indicators of the evaluation model were set with the general attributes of the product quality as the criterion level and the influencing factors as the sub-criterion level.Secondly,the AHP was used to qualitatively and quantitatively analyze relevant factors to construct a hierarchical judgment matrix,and the quality evaluation indicator weights for hemodylysis machines were determined with the consistency test.Finally,the operational principles of fuzzy mathematics were applied to establishing a fuzzy judgment matrix,and the evaluation results were calculated using Type Ⅳ fuzzy comprehensive evaluation model.Results The constructed fuzzy comprehensive evaluation model included one first-level indicator,seven second-level indicators and 21 third-level indicators.All the first-and second-level indicators passed the consistency tests.The evaluation results obtained with this model were practical and consistent with the hospital's long-term record data on hemodialysis machines.Conclusion The constructed fuzzy comprehensive evaluation model demonstrates a certain degree of scientific rigor for quality assessment of hemodialysis machines and can provide decision-making support for their procurement justification.[Chinese Medical Equipment Journal,2025,46(9):81-87]

Objective To conduct a comparative study on the biomechanical performance of using sutures for repairing inferior pole patellar fractures.Methods Compared to the normal patellar structure(Group A),four repair methods,namely,'Krackow'suture(Group B),"Kessler"fixation(Group C),'8-figure'mesh method(Group D),and modified suture bridge(Group E)were adopted.The static stiffness and dynamic stability of inferior pole patellar fractures fixed by each repair method were measured at 30°,60°,and 90° knee flexion.Results The stiffness at all flexion angles in Group E was closer to that in Group A,compared to other repair groups,followed by Group B,then Group D,and finally Group C.After the first cycle,at 30° knee flexion,Group C showed the greatest displacement,while Groups B and E had slightly larger displacements than the Group A,and the displacement of Group D was smaller than that of Group A.At 60° and 90° knee flexion,the displacement in all repair groups was smaller than that of Group A.After 200 cycles in the subsequent three cycles,displacement changes in all repair groups were smaller than those in Group A.Conclusions All repair methods were effective.In terms of biomechanical fixation performance,the modified suture bridge was superior to the'Krackow'suture and'8-figure'mesh,with Kessler fixation being the least effective.However,factors such as the injury severity,incision location,and surgical time should be comprehensively considered in actual clinical use,and it is recommended that the repair method should be selected in the following order:E,B,D,and C.

To perform the phylogenetic characterization of an isolated porcine rotavirus(PoRV)and investigate its pathogenicity in suckling mice and piglets.A G4P[23]genotype PoRV strain JSJR2023 was successfully isolated from the diarrheic piglet feces through propagation in MA104 cells.The viral proliferation kinetics were analyzed using TCID50 assays,followed by complete genome sequencing through Sanger sequencing platforms.Comprehensive genotyping and phylogenetic reconstruction were conducted using MEGA7.0 with maximum likelihood algorithms.Pathogenicity was assessed in the following animal models:5-day-old C57BL/6 mice and 3-day-old piglets.Multidimensional evaluation included clinical monitoring(diarrhea scoring,growth parameters),virological detection,and histopathological analysis of intestinal tissues.The virus strain JSJR2023 could replicate efficiently in MA104 cells,achieving peak titers of 107.5 TCID50/mL.Whole genome genotype analysis showed that the strain belonged to G4-P[23]-I5-R1-C1-M1-A8-N1-T1-E1-H1.Phylogenetic analysis indicated that the VP3 and NSP4 genes of JSJR2023 strain were most closedrelated to human species rotaviruses,suggesting genetic reassortment between human and porcine RV strains.The animal experiments in suckling mice showed that the JSJR2023 strain infection caused diarrhea symptoms,intestinal edema and congestion,and shedding of intestinal villus epithelial cells.The pathogenicity experiments in piglets showed that compared with the control group,the challenged group of pig-lets had severe diarrhea symptoms,accompanied by reduced appetite and listlessness.Post-mortem examination revealed that the intes-tines were significantly thinner,congested,and filled with yellow watery contents.The challenged piglets showed typical pathological changes such as thinning of the intestinal wall and shortening and shedding of intestinal villi.In conclusion,this study successfully iso-lated a human-porcine recombinant G4P[23]PoRV strain and established the infection models in suckling mice and piglets,providing important tools for investigating the pathogenic mechanism of PoRV,evaluating vaccines and developing antiviral drug.

To achieve efficient and rapid detection of duck astrovirus type 2(DAstV-2),RPA prim-ers and crRNA were designed and synthesized based on the conserved sequence of the ORF2 gene of DAstV-2.A detection method for DAstV-2 was constructed,integrating RPA nucleic acid ampli-fication,LwCas13a cleavage,and colloidal gold lateral flow dipstick visualization.The specificity,sensitivity,and concordance of this detection method were evaluated.The experimental results showed that the detection limit for the DAstV-2 recombinant plasmid standard was 1.2×101 cop-ies/μL,which is superior to the conventional RT-PCR method.The method can specifically detect DAstV-2 pathogenic nucleic acids without cross-reactivity with DAstV-1,DAstV-3,DAstV-4,duck plague virus(DEV),and duck tembusu virus(DTMUV).When testing liver tissue samples from ducks suspected of being infected with DAstV-2,the results obtained using this method were com-pletely consistent with those from real-time quantitative PCR,with a 100％concordance rate.How-ever,this method is simpler and faster to perform.The research indicates that the established RPA-CRISPR/Cas13a-LFD detection system has high sensitivity,strong specificity,and high accuracy,capable of completing rapid visual detection of DAstV-2 nucleic acids within 1 h at a constant tem-perature of 37 ℃,providing a new technical platform for the rapid diagnosis of DAstV-2.
