ObjectiveTo construct an automatic measurement model for palmar tilt and radial inclination suitable for traditional Chinese medicine （TCM） clinical scenarios， and to validate its accuracy and efficiency in TCM manipulative reduction settings. MethodsData on anteroposterior （AP） and lateral X-rays of distal radius fractures were collected from patients admitted to 18 TCM/ integrated TCM and western medicine hospitals in Jiangsu province between September 1st， 2023， and September 1st， 2024， via the Jiangsu Diagnosis and Treatment Big Data Platform for TCM Dominant Diseases. A medical image segmentation framework based on multi-scale feature fusion and edge-awareness was employed， combined with anatomical knowledge specific to TCM orthopedics， to optimize the feature extraction strategy of an artificial intelligence （AI） model. This framework enabled automatic segmentation of fracture regions and measurement of distal radius palmar tilt and radial inclination. The accuracy of the AI model in measuring radial inclination and volar tilt was validated， and the measurement time and average time gain rate of the AI model were compared to those of manual measurement. ResultsA total of 15,444 AP and lateral X-ray images of distal radius fractures were collected， and were divided into a training set （11,144 images， 5066 AP and 6078 lateral）， a validation set （3700 images， 1840 AP and 1860 lateral）， and an independent test set （600 images， 300 AP and 300 lateral） after preprocessing. In the measurement of 300 AP X-rays in the independent test set for radial inclination， when the degree error between AI measurement and manual measurement was ＜3° and ＜5°， AI measurement accuracy was 83% and 93%， respectively. In 300 lateral X-rays in the test set for palmar tilt， when AI measurements had an error of ＜3° and ＜5° compared to manual measurements， corresponding accuracy rate was 78% and 90%， respectively. For 50 X-ray images， AI measurement time was （1.37±0.05） min for radial inclination while manual measurement time was （22.57±2.52） min （P＜0.001）； in terms of palmar tilt， the AI measurement time was （1.33±0.14） min， shorter than （23.70±2.80） min for manual measurement time （P＜0.001）. Average time gain rates for manual and AI measurements were 93.93% and 94.39% respectively. ConclusionAn automatic measurement model for palmar tilt and radial inclination in distal radius fractures has been established， enabling more accurate and efficient assessment as well as providing a tool to support the quantitative evaluation of the efficacy of TCM manipulative reduction and large-sample clinical research.

Objective:To investigate the efficacy and safety of transarterial chemoembolization (TACE) combined with sintilimab and bevacizumab biosimilar in the treatment of unresectable hepatocellular careinoma (uHCC).Methods:The clinical data of 64 patients with unresectable HCC, who were admitted to the First Affiliated Hospital of Soochow University between January 2021 and December 2023, were retrospectively analyzed. The patients were divided into a combination group ( n=43, receiving TACE combined with sintilimab and bevacizumab biosimilar) and control group ( n=21, receiving only sintilimab and bevacizumab biosimilar). Survival curves were drawn by Kaplan-Meier method, and the median overall survival (mOS) and median progression-free survival (mPFS) were compared between the two groups. According to the mRECIST criterion, the objective response rate (ORR) and disease control rate (DCR) were compared between the two groups. The occurrences of adverse events in both groups were recorded. Results:The mOS and mPFS in the combination group were 22.3 months and 12.4 months, respectively, which in the control group was 11.6 months and 6.4 months, respectively. The differences between the two groups were statistically significant ( P=0.001 and P=0.002). The ORR and DCR in the combination group were 62.8% and 95.3% respectively, which were significantly higher than 19.0% and 57.1% respectively in the control group (all P<0.01). No statistically significant difference in the incidence of severe adverse events existed between the two groups ( P=0.518). Conclusion:TACE combined with sintilimab and bevacizumab biosimilar has efficacy and safety than sintilimab and bevacizumab biosimilar alone.

Purpose To investigate correlation of ADP ribosylation-like factor 6 interacting protein 4(ARL6IP4)expression with the pathological characteristics and clinical prognosis in primary colon cancer.Methods The ARL6IP4 mRNA expression in tumor and adjacent normal tissues of 133 colon cancer patients was analyzed by RT-qPCR,and its relationship with tumor location,pathological TNM stage,and 3-year survival prognosis was assessed.Additionally,ARL6IP4 protein expression was analyzed by immunohistochemistry in 30 cases,of which 16 cases were analyzed by immunofluorescence.Results The colon cancer presented significantly higher mRNA and protein levels of ARL6IP4 than adjacent normal tissues(t=4.221,P=5.200 × 10-5;t=7.421,P=3.537 × 10-8).The relative ex-pression level of ARL6IP4 mRNA in colon cancer was positively correlated with pathological TNM stage,N stage and M stage(P＜0.05),and negatively correlated with 3-year cumulative survival probability(P＜0.01).Additionally,sig-moid colon cancer presented significantly higher ARL6IP4 expression than other colon cancers,and at the cellular lev-el,ARL6IP4 was predominantly expressed in the cell nucleus.Conclusion The ARL6IP4 expression in colon cancer is higher than that in adjacent normal tissues,which is closely related to tumor metastasis and clinical prognosis.

Transarterial chemoembolization （TACE） is currently the primary treatment method for advanced liver cancer. This article elaborates on the current status of application of TACE in hepatocellular carcinoma from the aspects of existing techniques， patient selection， and efficacy assessment and summarizes the research advances and prospects of TACE combined with local treatment and systemic therapy， so as to provide new ideas for clinical practice and experimental studies.

Intrahepatic cholangiocarcinoma(ICC)is a relatively rare type of primary liver cancer,and its incidence rate has gradually increased in recent years.Due to its insidious onset and atypical clinical symptoms,most patients are already in the advanced stage of the disease at the time of confirmed diagnosis,and therefore,timely diagnosis and treatment are of great importance.Radical surgical resection is the standard treatment regimen for early-stage ICC patients,while systemic chemotherapy is the basic treatment for patients with advanced ICC and is often combined with interventional treatment,targeted therapy,and immunotherapy.This article reviews the advances in the diagnosis and treatment of ICC.

BACKGROUND:Combined radiation and wound injury appeared mainly in patients with tumor radiotherapy and nuclear radiation accidents.The radiation destroys the repair mechanism,resulting in delayed or prolonged wound healing.It still lacks an effective therapeutic strategy currently. OBJECTIVE:To prepare multifunctional wound dressings based on the multiple clinical symptoms of combined radiation and wound injury,which are designed to be antibacteria,promoted healing and analgesics. METHODS:Using levofloxacin,fibroin and lidocaine hydrochloride as raw materials,3D bioprinting technology was applied to prepare the multifunctional wound dressing.(1)The multifunctional dressing was placed on a fixed culture plate coated with Staphylococcus aureus,Escherichia coli and Pseudomonas aeruginosa,and incubated at 37 ℃ overnight to detect the diameter of the antibacterial zone.(2)40 Kunming mice were randomly divided into trauma group,radiation and trauma model group,treatment group and positive drug group,with 10 mice in each group.Mice in the radiation and trauma model group,treatment group and positive drug group were irradiated by 60Co gamma rays.After 1 hour of radiation,a full-layer skin defect wound with a diameter of 1 cm was made on the back of each mouse in the four groups.Normal saline was applied to the wounds of the trauma group and the radiation and trauma model group.Trethanolamine cream was applied to the wounds of the positive drug group.Multifunctional dressing was applied to the wounds of the treatment group.The dressing was changed every 2 days,and the treatment was continued for 14 days.Wound healing rate and serum interleukin-6 level were measured at 3,7 and 14 days after wound modeling.14 days after the wound modeling,the skin tissue of the wound was obtained and received hematoxylin-eosin staining,Masson staining and cytokeratin-14 immunohistochemical staining. RESULTS AND CONCLUSION:(1)3D-printed multifunctional wound dressing had good antibacterial activity.The antibacterial zone diameters against Staphylococcus aureus,Escherichia coli and Pseudomonas aeruginosa were(4.15±0.09),(4.18±0.23)and(4.35±0.13)cm,respectively.(2)With the extension of modeling time,the wound healed gradually.The wound healing rate of the treatment group and the positive drug group was higher than that of the radiation and trauma model group at 3,7 and 14 days after modeling(P<0.01,P<0.001).The wound healing rate of the treatment group was higher than that of the positive drug group.With the extension of modeling time,the serum interleukin level of mice increased first and then decreased.The serum interleukin level in the treatment group at 3,7 and 14 days after modeling was lower than that in the radiation and trauma model group.Hematoxylin-eosin staining and Masson staining exhibited that inflammatory cells infiltrated the granuloma tissue in the trauma group,and the dermal collagen fibers were densely arranged.The normal structure of epidermis and dermis was destroyed and inflammatory cells were infiltrated in the radiation and trauma model group.In the treatment group,normal skin mucosal tissue was observed,the epidermis was arranged closely,and the sweat glands,hair follicles and dermal collagen fibers were arranged regularly.In the positive drug group,the arrangement of epidermal layer was tight,and the arrangement of sweat glands,hair follicles and dermal collagen fibers was regular.Cytokeratin-14 immunohistochemical staining displayed that the epidermal tissue thickness in the treatment group was lower than that in the other three groups(P<0.01,P<0.001).(3)The results confirm that the 3D-printed multifunctional dressing has multiple functions of local anesthesia,anti-infection and promoting healing.
