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 investigate the experience of weight-bearing restriction in patients with diabetic foot ulcer, and to explore the influencing factors of weight-bearing restriction, so as to provide reference for individualized nursing intervention.Methods:Nineteen patients with diabetic foot ulcer from March to May 2023 in the Department of Endocrinology of Tongji Hospital Affiliate to Tongji Medical College of Huazhong University of Science and Technology were selected by purposive sampling method. Phenomenological research method was adopted to conduct semi-structural interviews on them. Based on the social ecosystem theory, Colaizzi 7-step analysis method was applied to collate and analyze the data.Results:Of the 19 patients interviewed, 12 were males and 7 were females. The age ranged from 45 to 78 years old. The results of the interview showed that the compliance of patients with diabetic foot ulcer was not optimistic, the influencing factors could be summed up into 3 themes and 13 sub-themes, the microscopic systems (daily needs, perceived benefits and risks, entrenched exercise habits, disease status, lack of belief in exercise therapy, stress and guilt), the middle-level system (doctor-nurse-patient trust relationship, health education, appropriate incentives, economic burden, family support), the macro-level system (limited medical resources, insufficient information support). Among them, the ten hindering factors were more than the five promoting factors, the hindrance factors included daily life demands, solidified exercise habit, hypoalgesia caused by peripheral neuropathy change, lack of belief in exercise therapy, stress and guilt, defects in health education, financial burden, insufficient family support, limited medical resources and insufficient information support. The promoting factors included the perception of behavioral benefits and risks, foot pain, doctor-patient trust and proper encouragement, and family support.Conclusions:The compliance of diabetic foot ulcer patients with weight restriction is affected by many factors, and intervention should be made from micro, middle and macro levels to improve the compliance of patients with weight restriction, promote wound healing, improve the quality of life and disease outcomes.

This paper aims to discuss the ideas and experience about the radiology residency training system of Canada with a presentation of its base accreditation standards for five aspects, competency goals for seven roles, four stages of training arrangement, and two types of final assessment questions. Although the Canada's radiology residency program differs from China's standardized resident and specialist training programs for radiology, there are still several points that are worth referencing, including emphasizing the training priority of competency goals, providing a specific basis for the stratification of training, offering clear guidance for the implementation of training content, and improving assessment methods to focus on competency goals. These points are of great value for improving the standardized radiology resident and specialist training programs in China, so as to provide a reference for the training of excellent radiologists in China.

Purpose: Models for predicting perforation during endoscopic resection (ER) of gastric submucosal tumors (SMTs) originating from the muscularis propria (MP) are rare. Therefore, this study was conducted to determine important parameters in endoscopic ultrasonography (EUS) images to predict perforation and to build predictive models. Methods: Consecutive patients with gastric SMTs originating from the MP who received ER from May 1, 2013 to January 15, 2021 were retrospectively reviewed. They were classified into case and control groups based on the presence of perforation. Logistic multivariate analysis was used to identify potential variables and build predictive models (models 1 and 2: with and without information on tumor pathology, respectively). Results: In total, 199 EUS procedures (194 patients) were finally chosen, with 99 procedures in the case group and 100 in the control group. The ratio of the inner distance to the outer distance (I/O ratio) was significantly larger in the case group than in the control group (median ratio, 2.20 vs. 1.53; P<0.001). Multivariate analysis showed that age (odds ratio [OR], 1.036 in model 1; OR, 1.046 in model 2), the I/O ratio (OR, 2.731 in model 1; OR, 2.372 in model 2), and the pathology of the tumors (OR, 10.977 for gastrointestinal stromal tumors; OR, 15.051 for others in model 1) were risk factors for perforation. The two models to predict perforation had areas under the curve of 0.836 (model 1) and 0.755 (model 2). Conclusion EUS was useful in predicting perforation in ER for gastric SMTs originating from the MP. Two predictive models were developed.

Background/Aims: The accuracy of endosonographers in diagnosing gastric subepithelial lesions (SELs) using endoscopic ultrasonography (EUS) is influenced by experience and subjectivity. Artificial intelligence (AI) has achieved remarkable development in this field. This study aimed to develop an AI-based EUS diagnostic model for the diagnosis of SELs, and evaluated its efficacy with external validation. Methods: We developed the EUS-AI model with ResNeSt50 using EUS images from two hospitals to predict the histopathology of the gastric SELs originating from muscularis propria. The diagnostic performance of the model was also validated using EUS images obtained from four other hospitals. Results: A total of 2,057 images from 367 patients (375 SELs) were chosen to build the models, and 914 images from 106 patients (108 SELs) were chosen for external validation. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the model for differentiating gastrointestinal stromal tumors (GISTs) and non-GISTs in the external validation sets by images were 82.01%, 68.22%, 86.77%, 59.86%, and 78.12%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in the external validation set by tumors were 83.75%, 71.43%, 89.33%, 60.61%, and 80.56%, respectively. The EUS-AI model showed better performance (especially specificity) than some endosonographers.The model helped improve the sensitivity, specificity, and accuracy of certain endosonographers. Conclusions We developed an EUS-AI model to classify gastric SELs originating from muscularis propria into GISTs and non-GISTs with good accuracy. The model may help improve the diagnostic performance of endosonographers. Further work is required to develop a multi-modal EUS-AI system.

ObjectiveTo study the potential quality marker （Q-marker） of Tinosporae Radix associated with efficacy of "relieving sore throat" based on ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS）， multivariate statistical analysis （MSA）， and network pharmacology. MethodUPLC-Q-TOF-MS was used to identify the main chemical components in 18 batches of Tinosporae Radix. On this basis， principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA） were employed to screen out the main marker components that caused differences between groups. Moreover， network pharmacology technology was applied to predict the potential "sore throat-relieving" components， and the molecular docking between the common components resulting from MSA and network pharmacology and the core targets was carried out to verify the marker components. ResultA total of 17 compounds， including alkaloids， diterpenoid lactones， and sterols， were identified by UPLC-Q-TOF-MS. Five main differential components were found by MSA： Columbamine， jatrorrhizine， palmatine， menisperine， and columbin. Network pharmacology analysis yielded six compounds： tetrahydropalmatine， palmatine， menisperine， fibleucin， neoechinulin A， and columbin which were selected as potential "sore throat-relieving" components of Tinosporae Radix. They may relieve sore throat by acting on interleukin-6， epidermal growth factor receptor， prostaglandin G/H synthase 2， matrix metalloproteinase-9， proto-oncogene tyrosine-protein kinase Src and other targets， and regulating Hepatitis B， influenza A， human T-cell virus infection， human cytomegalovirus infection， coronavirus disease-2019， and other signaling pathways. The common active components in Tinosporae Radix resulting from MSA and network pharmacology analysis were palmatine， menisperine， and columbin， which had high binding affinity with six core targets and can be used as the Q-marker components of Tinosporae Radix in "relieving sore throat". ConclusionThis study predicts the "sore throat-relieving" Q-marker of Tinosporae Radix， which lays a basis for developing the quality standard of Tinosporae Radix based on the efficacy and improving the quality evaluation system of the medicinal.

Monkeypox is a zoonotic disease.Previous studies have shown that children are vulnerable to monkeypox and are also at high risk for severe disease or complications.In order to improve pediatricians′ understanding of monkeypox and achieve early detection, early diagnosis, early treatment and early disposal, the committee composed of more than 40 experts in the related fields of infectious diseases, pediatrics, infection control and public health formulate this expert consensus, on the basis of the latest clinical management and infection prevention and control for monkeypox released by the World Health Organization (WHO), the guidelines for diagnosis and treatment of monkeypox (version 2022) issued by National Health Commission of the People′s Republic of China and other relevant documents.During the development of this consensus, multidisciplinary experts have repeatedly demonstrated the etiology, epidemiology, transmission, clinical manifestations, laboratory examinations, diagnosis and differential diagnosis, treatment, discharge criteria, prevention, case management process and key points of prevention and control about monkeypox.

Objective:To detect the common pathogenic bacteria in rat wounds using electronic nose so as to explore the feasibility of electronic nose for rapid screening of pathogenic bacteria in clinic.Methods:The wound was cutted from the left and right side of the psoas muscle of 45 SD rats. The type of standard bacterial fluids applied to the wound was divided into Staphylococcus aureus group, Escherichia coli group, Pseudomonas aeruginosa group, Acinetobacter baumannii group and Klebsiella pneumoniae group according to the random number table, with 9 mice per group. Three days later, the wound pus was sent to culture. Five standard bacterial fluids were detected by electronic nose, and the overall recognition rate and individual recognition rate of standard bacterial fluids were calculated by neural network (BP). The wound pus in each group was detected by electronic nose to visually compare the overlap degree of the radar map of the wound pus with the standard bacterial fluid characteristic radar map. The detection rate of wound pus in each group by electronic nose was compared. The wound pus in each group was submitted for examination, and the clinical detection rate of wound pus in each group was compared. The consistency was compared between electronic nose test and clinical test.Results:The overall BP identification rate of five standard bacteria liquid was 93.2%. The BP single identification rate of the Staphylococcus aureus, Escherichia coli and Klebsiella pneumoniae reached over 99.0%, and was more than 88.0% for Pseudomonas aeruginosa and Acinetobacter baumannii. The radar pattern of wound pus was highly overlapped with the characteristics of radar pattern of standard bacterial fluid. The detection rate of wound pus by electronic nose was the highest (100.0%) in Pseudomonas aeruginosa group and Escherichia coli group, followed by 88.9% in Klebsiella pneumoniae group and 72.2% in Pseudomonas aeruginosa group and Acinetobacter baumannii group. Using electronic nose, the detection rate in Pseudomonas aeruginosa group and Acinetobacter baumannii group was significantly different from that in Staphylococcus aureus group and Escherichia coli group ( P<0.05). The clinical detection rate of wound pus was 100.0% in Staphylococcus aureus group, Escherichia coli group and Klebsiella pneumoniae group, 94.4% in Pseudomonas aeruginosa group and 66.7% in Acinetobacter baumannii group. The clinical detection rate in Acinetobacter baumannii group differed significantly compared to that in Staphylococcus aureus group, Escherichia coli group and Klebsiella pneumoniae group ( P<0.05), while there was no significant difference between Acinetobacter baumannii group and Pseudomonas aeruginosa group ( P>0.05). Comparison of detection rate of wound pus between electronic nose and clinic examination showed a Kappa coefficient of 0.475. Conclusions:The animal wound pus detected by electronic nose can obtain a feature map with high repeatability compared to the standard bacterial fluid. The electronic nose detection has a medium degree of consistency with clinical detection, providing an experimental basis for the feasibility of using electronic nose to rapidly screen types of pathogenic bacteria.

Objective:To investigate the effect of genetic polymorphisms of TPMT*2 rs1800462, TPMT*3B rs1800460, TPMT*3C rs1142345, and NUDT15 rs116855232 on the tolerance of 6-mercaptopurine (6-MP) therapy in adult acute lymphoblastic leukemia (ALL) .Methods:A total of 216 adult patients who were diagnosed with ALL and treated with cyclophosphamide, cytarabine, and 6-MP [complementary and alternative medicine (CAM) regimen] from September 2015 to December 2019 were included. Polymorphisms were detected by TaqMan SNP Genotyping Assay. Combined with clinical data, the influence of genetic polymorphism on the tolerance of 6-MP in the treatment of ALL was analyzed.Results:Among the 216 patients, 185 (85.65%) patients had B-ALL and 31 (14.35%) patients had T-ALL. 216 (100%) patients had CC genotype for both TPMT*2 rs1800462 and TPMT*3B rs1800460. The number of TT and TC genotypes for TPMT*3C rs1142345 was 209 (96.76%) and 7 (3.24%) , respectively. The allele frequency was 1.62% for TPMT*3C rs1142345. The number of CC, CT, and TT genotypes for NUDT15 rs116855232 was 166 (76.85%) , 48 (22.22%) , and 2 (0.93%) , respectively. The allele frequency was 12.04% for NUDT15 rs116855232. The TPMT*3C rs1142345 mutant group (TC+CC genotype) had less transfusion volume of packed red blood cell than the wild group (CC genotype) ( P=0.036) , and the mutant group (TC+CC genotype) had a higher risk to develop hepatotoxicity (increased aspartate aminotransferase) than the wild group (CC genotype) ( OR=9.559, 95% CI 1.135-80.475, P=0.038) . The durations of white blood cells (WBC) <1×10 9/L and absolute neutrophil count (ANC) <0.5×10 9/L in the NUDT15 rs116855232 mutation group (CT+TT genotype) were longer than that in the wild group (CC genotype) ( P=0.005, P=0.007) , and the transfusion volume of apheresis-derived platelets in the mutant group (CT+TT type) was greater than that in the wild group (CC genotype) ( P=0.014) . Conclusion:Genetic polymorphism of TMPT and NUDT15 has an effect on the tolerance of 6-MP in the treatment of adult ALL. Detecting genotypes of patients with ALL before treatment helps to optimize the dosage of 6-MP, which may help shorten the bone marrow suppression duration and reduce blood transfusion volume.
