This study aims to review the current status and development trends of digital TCM (Traditional Chinese Medicine) specimen museums, providing a theoretical basis for their future construction. By systematically organizing literature and materials, practical experiences in platform architecture design, content planning, and technical implementation were summarized. The research results show that digital technology has significant application value in the TCM field. Currently, some Food and Drug Control Institutes have formed diverse construction achievements by integrating regional characteristics with technological innovation. However, current TCM specimen museums generally still face many challenges, such as insufficient digitalization. In conclusion, the digitalization of TCM specimen museums has become an inevitable trend in the industry. Targeted measures are urgently needed to solve existing problems and promote the sustainable development of digital TCM specimen museums. It is suggested to strengthen the standardization of data collection and storage, deepen the integration of technologies such as 3D, AR, and AI into the construction of specimen museums, and at the same time promote the spatial design combining regional culture with TCM. This will help create "one museum with one feature for one region" digital TCM specimen museums, further promoting their sustainable development and facilitating the digital inheritance of TCM.

Objective: This study aimed to investigate a mature three-dimensional reconstruction technique using Cordyceps sinensis as an example, to establish the methodology for creating digital specimens of traditional Chinese medicine. This can lay a solid the foundation for digitizing traditional Chinese medicine samples and identifying their characteristics.
Methods: Based on the research results related to the characteristics identification of Cordyceps sinensis generated by the research team and survey of the existing literature, a characteristic identification evaluation method was designed. The key technical factors of three-dimensional reconstruction (measurement methods, repeatability and reproducibility, synthetic computation, digital specimen format, and color correction) were investigated. A methodology for constructing three-dimensional digital specimens of Cordyceps sinensis was established, and several types of samples (various origins, different completeness, diverse types) were subjected to three-dimensional reconstruction to validate this novel method.
Results: Through this methodological research, the application of three-dimensional reconstruction technology in the construction of digital specimens of Cordyceps sinensis was elegantly established. This method can accurately reproduce all the characteristic identification features of the physical samples. All the samples could be reconstructed into their corresponding three-dimensional digital specimens.
Conclusion: Overall, combining computer-aided three-dimensional reconstruction technology and methodology developed by us can create three-dimensional digital specimens of Cordyceps sinensis and provide a fundamental assessment for restoring the characteristic identification features.

ObjectiveTo analyze the influencing factors of hepatic fibrosis in patients with Wilson's disease （WD） and to develop and validate a predictive model for hepatic fibrosis in WD that integrates traditional Chinese medicine （TCM） syndromes and modern biomarkers， thus providing a basis for early identification of high-risk populations and medical intervention. MethodsThe clinical data of 220 WD patients diagnosed in the Department of Encephalopathy， The First Affiliated Hospital of Anhui University of Chinese Medicine between January 2010 and December 2024 were retrospectively collected. Through a random number table， patients were assigned into a training set （154 patients） and a validation set （66 patients） in a 7∶3 ratio. Univariate COX regression， LASSO regression analysis， and multivariate COX regression analysis were performed to identify independent influencing factors for hepatic fibrosis in WD patients， and a clinical prediction model was established based on these factors. The discrimination， calibration， and clinical utility of the model were evaluated based on the area under the receiver operating characteristic curve （AUC）， calibration curves， and decision curve analysis （DCA）， respectively. ResultsA total of 220 patients were included. The syndrome of combined phlegm and stasis， triglycerides （TG）， laminin （LN）， and male gender were identified as independent risk factors for hepatic fibrosis in WD patients， while TCM intervention and high-density lipoprotein cholesterol （HDL-C） were protective factors. The C-index indicated excellent discriminative ability （training set： 3-year AUC=0.908， 5-year AUC=0.869， 7-year AUC=0.829； validation set： 3-year AUC= 0.898， 5-year AUC=0.780， 7-year AUC=0.743）. Calibration curves showed good consistency. DCA demonstrated the clinical net benefit probabilities across different risk thresholds at various time points. ConclusionThe predictive model established in this study has high accuracy and can be conveniently used for the early identification and risk prediction of hepatic fibrosis in patients with WD.

The Medical Cases of WU Jutong （《吴鞠通医案》） proposes the principle of "treating all Bi （痹） diseases through taiyin"， which forms the basis for analyzing WU Jutong's understanding of the causes， mechanisms， and treatments of Bi （痹） diseases， providing a reference for clinical diagnosis and treatment. Through an interpretation of the phrase "treating all Bi （痹） diseases through taiyin"， it is suggested that Bi （痹） diseases is primarily caused by dampness， necessitating a focus on spleen and lung in treatment. WU emphasized four main causes of Bi （痹） diseases （wind， cold， dampness， and heat）， with dampness being the predominant factor. The disease location is initially in lung， for which external dampness invades lung first， and internal dampness obstructs the source of water metabolism， impeding lung qi and qi failing to disperse， then dampness further accumulates in the joints， leading to Bi （痹） diseases. WU Jutong proposed the modified Mufangji Decoction （木防己汤） as the foundational prescription for treating Bi （痹） diseases. By comparing the similarities and differences between the modified and original Mufangji Decoction， and analyzing the adjustments in herbal prescriptions， the clinical characteristic of "treating all Bi （痹） diseases through taiyin" is further substantiated.

Objective To investigate the anatomical structure and surface location of the Lieque(LU7)acupoint.Methods Firstly,the anatomical localization descriptions of the Lieque(LU7)acupoint from classical medical literature were reviewed and summarized.A total of 21 participants were recruited from Shandong Provincial Hospital Affiliated to Shandong First Medical University from January to March 2025.A Cartesian coordinate system was established over the Lieque(LU7)region on the right forearm.Following standardized manual pressure stimulation,the coordinates of the participant′s reported acupoint sensations were recorded.Based on surface pressure mapping result,10 participants were arbitrarily selected for acupuncture intervention.Upon elicitation of acupoint sensation,the ultrasound imaging was used for real-time visualization of anatomical spatial relationships between the needle tip and distal radial osseous landmarks.Five red latex-perfused adult upper limb specimens were selected for microdissection of the Lieque(LU7)regions pre-localized via ultrasonography,achieving definitive structural characterization of its anatomical strata.Another 10 participants were arbitrarily selected to find the physical structure of the Lieque(LU7)acupoint using ultrasound,and the similarities and differences of acupoint sensation responses were verified using acupuncture needle insertions into both the demarcated zone and peripheral tissues.Results The descriptions of the localization of the Lieque(LU7)acupoint in ancient books can be summarized as"one and a half cun above the wrist side"longitudinally,and"at the intersection head,between two tendons and two bones in the hollow"transversely.During surface pressure application,the sites of the participant′s elicited acupoint sensation were anatomically concentrated in the proximal depression adjacent to the radiopalmar ridge,specifically at the transitional interface between the extensor pollicis brevis tendon and scaphoid bone.During acupuncture-induced acupoint sensation,ultrasound imaging demonstrated that the location of the needle tip was located within the proximal depression adjacent to the radiopalmar ridge,accompanied by arterial hemodynamic perfusion signals into adjacent osseous interfaces.Microdissection findings revealed perforating branches of the radial artery traversing the cortical bone interface within the Lieque(LU7)acupoint region.Acupuncture stimulation at the proximal depression adjacent to the radiopalmar ridge elicited consistent acupoint sensations in all 10 participants,and the acupoint sensations differed from those of other surrounding tissues.Conclusion The anatomical structure of Lieque(LU7)acupoint is located within the proximal depression adjacent to the radiopalmar ridge,characterized by the presence of"hilus of bone"structure.

Purpose: Erectile dysfunction (ED) is a common male sexual dysfunction. Gut microbiota plays an important role in various diseases. To investigate the effects and mechanisms of intestinal flora dysregulation induced by high-fat diet (HFD) on erectile function. Materials and Methods: Male Sprague–Dawley rats aged 8 weeks were randomly divided into the normal diet (ND) and HFD groups. After 24 weeks, a measurement of erectile function was performed. We performed 16S rRNA sequencing of stool samples. Then, we established fecal microbiota transplantation (FMT) rat models by transplanting fecal microbiota from rats of ND group and HFD group to two new groups of rats respectively. After 24 weeks, erectile function of the rats was evaluated and 16S rRNA sequencing was performed, and serum samples were collected for the untargeted metabolomics detection. Results: The erectile function of rats and the species diversity of intestinal microbiota in the HFD group was significantly lower, and the characteristics of the intestinal microbiota community structure were also significantly different between the two groups. The erectile function of rats in the HFD-FMT group was significantly lower than that of rats in the ND-FMT group. The characteristics of the intestinal microbiota community structure were significantly different. In the HFD-FMT group, 27 metabolites were significantly different and they were mainly involved in the several inflammation-related pathways. Conclusions Intestinal microbiota disorders induced by HFD can damage the intestinal barrier of rats, change the serum metabolic profile, induce low-grade inflammation and apoptosis in the corpus cavernosum of the penis, and lead to ED.

In response to the new requirements for course instruction outlined in the revised training program for medical imaging program, this study integrated medical imaging technology courses based on the principle of outcome-oriented education and by leveraging self-developed digital resources, with imaging methods as the entry point. The core elements of the course teaching were re-optimized and reorganized to transcend the temporal and spatial limitations of course delivery, enabling the rational application of diverse teaching methods. This approach facilitated the integration of knowledge across three specialized courses, namely medical imaging physics, medical imaging equipment, and medical imaging examination techniques, and achieved full-dimensional and whole-process teaching evaluation. While reducing the number of hours allocated to theoretical instruction, the teaching objectives were achieved with high quality, providing a reference for the integration of digital technologies into the teaching of medical imaging and related disciplines.

Given the lack of annotations for key lung organs and tissues in existing public datasets,this study collected 863 cases of chest CT scan images and constructed the first comprehensive dataset containing annotations of pulmonary vessels,airways,and nodules using a semi-automated method that combines computer vision algorithms with manual corrections by radiologists.On this basis,a lung nodule segmentation model based on multi-task learning is proposed.By incorporating annotations of pulmonary vessels(pulmonary arteries and veins)and the trachea to enhance model's ability to learn lung features,the proposed model reduces the false discovery rate in lung nodule detection,and improves generalization ability.Additionally,the use of larger image patches further optimizes model performance.The trained VAAN_128 model achieves the best performance,with a Dice coefficient of 0.694 and a false discovery rate of 0.210 for lung nodule segmentation.Moreover,it simultaneously provides accurate segmentation results of pulmonary vessels and the trachea,assisting in the formulation of more precise diagnosis and treatment plans.Based on the VAAN_128 model,a software system for navigation and localization in biopsy procedures is developed.In clinical practice,this system can assist physicians in accurately locating lung nodules,distinguishing critical tissues,and improving preoperative planning efficiency.This provides precise and efficient technical support for early diagnosis and disease monitoring of lung diseases,and is of great significance for path planning in clinical navigation system and future lung imaging research.

Objective:To investigate the safety and efficacy of the artery-first approach pancreaticoduo-denectomy (PD) combined with portal vein/superior mesenteric vein (PV/SMV) resection and reconstruction for pancreatic head malignancies.Methods:A retrospective analysis was conducted on 322 patients who underwent PD with PV/SMV resection and reconstruction at the Hepatobiliary Pancreatic Surgery Department of the First Hospital Affiliated to Naval Medical University between January 2016 and December 2022. Patients were divided into the artery-first approach PD group (AFA-PD group, n=165) and standard PD group (SPD group, n=157) based on surgical approach. Baseline characteristics, surgical outcomes, postoperative outcomes, pathological results and survival data were compared between two groups. Results:Compared to the SPD group, the AFA-PD group exhibited significantly reduced intraoperative blood loss (500 ml vs 600 ml), lower rates of obvious intraoperative blood loss (≥1 000 ml: 25.45% vs 40.13%), and decreased transfusion requirements (26.67% vs 52.87%). Postoperatively, the AFA-PD group demonstrated lower incidence of grade B/C pancreatic fistula (10.30% vs 19.75%) and higher textbook outcome achievement (78.79% vs 66.24%). Pathologically, the AFA-PD group achieved superior lymph node yield (20 nodes vs 18 nodes) and higher R 0 resection rates (79.39% vs 64.33%), particularly at the posterior pancreatic margin (96.97% vs 91.72%, P=0.040), SMA margin (92.07% vs 82.17%), and SMV margin (88.48% vs 78.98%). Multivariate logistic regression identified arterial invasion >180°, venous invasion >180°, lymph node metastasis, and the artery-first approach as independent predictors of R 0 resection. The AFA-PD group showed prolonged median survival (19.17 month vs 15.73 month). All aforementioned differences were statistically significant (all P value <0.05). Conclusions:The artery-first approach PD combined with PV/SMV resection and reconstruction is safe and effective for pancreatic head malignancies, significantly improving R 0 resection rates and patients' survival outcomes.
