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 effects of treadmill training with different intensities on tendon-bone healing in rats after anterior cruciate ligament (ACL) reconstruction.Methods:Of the 99 adult male Sprague-Dawley (SD) rats used for this study, 90 were randomly selected to undergo ACL reconstruction with autologous caudal tendon. Two weeks after the surgical reconstruction, the 90 SD rats were randomized into a low-intensity group (group L, n=30) subjected to treadmill training at a speed of 12 m/min, a moderate-intensity group (group M, n=30) subjected to treadmill training at a speed of 18 m/min, and a free group (group C, n=30) subjected to free activities in the cage as a model control. The other 9 rats were set as a blank control (group N, n=9) subjected to no treatment at all. The treadmill training started at the end of 2 weeks after surgical reconstruction. Hematoxylin-eosin (HE), micro-CT analysis, mechanical testing, real-time quantitative polymerase chain reaction (qPCR) and western blot analysis were used to evaluate the quality of tendon-bone healing. Results:There were no significant differences in the areas of femoral and tibial lateral bone tunnels or the total bone volume ratio (BV/TV) between the 3 groups 2 weeks after surgery ( P > 0.05). At 4 weeks and 8 weeks after surgery, the areas of lateral tibial bone tunnel and lateral femoral tunnel in groups C, M and L showed a decreasing trend ( P < 0.05) while the BV/TV of lateral femoral tunnel and the BV/TV of lateral tibial tunnel in groups C, M and L showed an increasing trend ( P < 0.05). At 8 weeks after surgery, HE staining showed that the tendon-bone healing was the most mature in group L, followed by group M, and the least mature in group C, showing statistically significant differences ( P < 0.05). The stiffness and maximum failure load showed an increasing trend from group C to group M to group L to group N. The stiffness in group M and the stiffness and maximum failure load in groups N and L were significantly higher than those in group C ( P < 0.05). The relative mRNA expression levels of osteopontin (OPN) and collagen type Ⅱ alpha 1 chain gene (COL2 α 1), as well as the protein expression levels of osteocalcin, OPN, and COL2 α 1, showed an increasing trend from group C to group M to group L, showing significant differences between pairwise comparisons ( P < 0.05). Conclusions:Treadmill training starting at the end of 2 weeks after surgery is beneficial to tendon-bone healing and improves the biomechanical strength of the tendon-bone complex. Low-intensity mechanical stimulation is more conducive to new bone formation and collagen fiber remodeling in the tendon-bone complex.

Most patients with spinal cord injury suffer from limb motor dysfunction. Given drugs, surgery and other conventional treatments are often not effective, the patients can only rely on a wheelchair to move or even lie in bed for a long time, seriously affecting their quality of life. Brain computer interface (BCI) technology provides a non-muscular pathway for the recovery of motor function in patients with spinal cord injury, which allows the patients to recover partial motor function through the normal function of their own non-diseased spinal cord or external mechanical devices. After decades of development of BCI technology, signal collection devices can identify and collect the motor signals of the brain more accurately, transform the signal by characteristic analysis, and implement the brain command by using the output device. A large number of experimental and clinical studies have also proved that the application of BCI technology in patients with spinal cord injury can partially improve the motor function of upper and lower limbs. Therefore, BCI technology has attracted more and more attention. The authors summarized the BCI technology and its influence on motor function rehabilitation in patients with spinal cord injury, so as to provide a reference for the rehabilitation of motor function in patients with spinal cord injury.

Objective    To explore the safety and effectiveness of different interventional approaches for the treatment of patent ductus arteriosus (PDA) in children. Methods    The children (≤7 years) who underwent interventional treatment for PDA from 2019 to 2020 in our hospital were retrospectively included. The patients were divided into 3 groups according to the procedures: a conventional arteriovenous approach group, a simple venous approach group, and a retrograde femoral artery approach group. The clinical efficacy of the patients was compared. Results     A total of 220 patients were included. There were 78 males and 142 females, with an average age of 3.21±1.73 years, weight of 14.99±5.35 kg, and height of 96.19±15.77 cm. The average diameter of the PDA was 3.35±1.34 mm. A total of 85 patients received a conventional arteriovenous approach, 104 patients received a simple venous approach, and 31 patients received a retrograde femoral artery approach. The diameter of PDA in the retrograde femoral artery group was smaller than that in the other two groups (3.44±1.43 mm vs. 1.99±0.55 mm; 3.69±1.17 mm vs. 1.99±0.55 mm, P<0.001); the contrast medium usage [40 (30, 50) mL vs. 20 (20, 30) mL; 35 (25, 50) mL vs. 20 (20, 30) mL, P≤0.001] and operation time [32 (26, 44) min vs. 25 (23, 30) min; 29 (25, 38) min vs. 25 (23, 30) min, P<0.05] in the simple venous approach group were significantly less or shorter than those in the other two groups; the length of hospital stay of the conventional arteriovenous group was longer than that in the other two groups [3 (3, 5) d vs. 4 (3, 6) d; 4 (3, 5) d vs. 4 (3, 6) d, P<0.05]. There was no significant difference in postoperative complications. Conclusion    It is safe and effective to close PDA through simple venous approach. The retrograde femoral artery approach has the advantage of simplifying the surgical procedure for PDA with small diameters.

A large spontaneous mass on the dorsal abdomen near the hip joint was found in an aged female Tupaia belangeri subsp. yaoshanensis after 5 years of routine feeding. The tumor in the diseased tree shrew was huge, with an intact surface and no ulceration; however, it caused inconvenience in movement while maintaining a good mental state. After inhalation anesthesia with isoflurane (2%-4%), the tree shrew was euthanized after the tree shrew entered deep anesthesia. Anatomical dissection of the tumor, the tumor boundary was unclear and infiltrated into surrounding tissues. HE staining showed that small focal pleomorphism and large areas of adipocytes were seen in the tumor tissue. The pleomorphic sarcoma area was mainly composed of atypical epithelioid cells with easily visible nuclear divisions. The size of the adipocytes was significantly different, and more pleomorphic adipocytes were seen. The cell volume was large, the nucleus was deeply stained and deformed, the edge was impressed, and the cytoplasm was seen with multiple vesicular lipid droplets. Immunohistochemical results showed that the tumor cells were positive for Vimentin, the small focal polymorphic adipocyte nucleus was positive for S-100, and Ki-67 exhibited a higher proportion of positivity. Combined with HE staining and immunohistochemical results, the spontaneous tumor in this tree shrew was comprehensively diagnosed as pleomorphic liposarcoma.

ObjectiveTo observe the primary tumor of tree shrews and to provide a basis for studying the pathogenesis and prevention of trichoepithelioma. MethodsA tumor was discovered in the chest and abdomen of a tree shrew during natural cultivation. The tree shrew was anesthetized, and the tumor was surgically removed. Hematoxylin and eosin (HE) staining and immunohistochemical staining were performed on the tumor tissue after paraffin section, and the tumor cells were isolated and cultured by passage. The isolated tumor cells were subcutaneously injected into healthy tree shrews and nude mice. The tumorigenesis of tumor cells in vivo was observed once a day, with nude mice continuously observed for 2 months and tree shrews observed for more than 6 months. ResultsHE staining showed that the basal cells in the dermis were arranged as a whole, like a string of petals, forming nests and stripe-like structures with clear boundaries. The observation results after magnification revealed that the tumor cells were arranged in a pallisade-like and basal pattern, with deep nuclear staining and minimal cytoplasmic. Immunohistochemical staining showed the high expression of CK protein and low proportion expression of ki-67 protein in tumor cells, as well as the high expression of vimentin and low expressions of Bcl2 and CD10 in tumor cell mesenchyme. The isolated tumor cells grew well in DMEM medium containing 10% fetal bovine serum and could be cultured by passage, but no tumor formation was observed in healthy tree shrews and nude mice inoculated with tumor cells. ConclusionCombined with the location of the tumor, overall morphology, HE staining, and immunohistochemical results, the thoracoabdominal mass of the tree shrew was diagnosed as a trichoepithelioma.

Objective:To evaluate and summarize evidence related to structured skin care for incontinence-associated dermatitis (IAD) in adult inpatients, so as to provide a reference for clinical nursing decision-making.Methods:Clinical decisions, guidelines, evidence summaries, systematic reviews, expert consensus related to structured skin care for IAD in adult inpatients were retrieved by computer in British Medical Journal Best Practice, UpToDate, Joanna Briggs Institute Evidence-Based Health Care Centre in Australia, Canadian Registered Nurses Association of Ontario, Guidelines International Network, National Guideline Centre, National Institute for Health and Care Excellence, Medlive, the Cochrane Library, PubMed, Web of Science, CINAHL, Embase, WanFang Data, VIP, China National Knowledge Infrastructure, China Biomedical Literature Database. The retrieval time limit was from the establishment of the database to April 30, 2021. Two investigators independently assessed the quality of the included evidence and the level of recommendation.Results:A total of 14 articles were included, involving 2 clinical decisions, 1 practice guideline, 6 evidence summaries, 2 systematic reviews, and 3 expert consensus. A total of 29 best evidence was compiled from 4 aspects of structured skin care assessment, cleansing, moisturizing and isolation.Conclusions:Medical and nursing staff should integrate evidence with clinical scenarios and patient preferences to make optimal clinical decisions on structured skin care and improve the quality of care for adult inpatients with IAD.

Objective:To investigate the differences of spontaneous neural activity and functional connectivity between bilateral symmetrical voxels in the local brain regions at resting-state of methamphetamine (MA) dependent patients and healthy controls (HCs).Methods:Forty-six MA-dependent patients, admitted to and received drug rehabilitation treatment for the first time in our hospital from February 2014 to October 2019, and 46 HCs matched with age, gender and education level during the same period were enrolled in this study. The resting state functional magnetic resonance imaging (rs-fMRI) data of these subjects were collected; the static and dynamic regional homogeneity (ReHo, d-ReHo) and static and dynamic voxel-mirrored homotopic connectivity (VMHC, d-VMHC) were used to evaluate MA-related alterations of brain spontaneous activity and interhemispheric functional connectivity. The correlations of brief psychiatric rating scale (BPRS) scores with above values in the brain regions with significant inter-group differences were analyzed.Results:As compared with the HCs, the MA-dependent patients had significantly decreased ReHo in the left medial orbitofrontal cortex (mOFC), and significantly increased d-ReHo in the left mOFC, left middle frontal gyrus, bilateral inferior frontal gyrus, left precentral gyrus and left postcentral gyrus ( P<0.05). As compared with the HCs, the MA-dependent patients had significantly decreased VMHC in the bilateral mOFC, precentral gyrus and postcentral gyrus ( P<0.05). The ReHo, VMHC, d-ReHo, and d-VMHC were not significantly correlated with total scores and each factor scores of BPRS, and total dose of MA (after removing outliers) in MA-dependent patients ( P>0.05). Conclusion:During resting state, MA-dependent patients show obvious abnormalities in the coordination and stability of spontaneous neural activity and the coordination of interhemispheric activity in local brain regions, especially in the mOFC; abnormal ReHo, d-ReHo and VMHC in left mOFC may be important neuroimaging biomarkers for MA-dependence.
