ObjectiveTo compare the clinical efficacy of traditional Chinese medicine （TCM） manipulative reduction combined with small splint fixation versus surgical treatment for type A distal radius fracture （DRF） and to explore the factors influencing the choice of treatment. MethodsA multi-center retrospective study was conducted， collecting data from 1237 type A DRF patients treated in 11 hospitals in Jiangsu province from September， 2023 to April， 2025. Among them， 851 patients in the TCM group received manipulative reduction combined with small splint fixation， and 386 patients in the surgical group underwent open reduction and internal fixation. Visual analog scale （VAS） scores for pain and radiographic indicators including palmar tilt， ulnar deviation， and radial height were compared before treatment， 5-7 days after treatment， and 4-6 weeks after treatment. The wrist joint function scores including Dienst and Gartland-Werley scores at 12 weeks after treatment were recorded. Subgroup analysis was conducted for the excellent rate of Dienst and Gartland-Werley scores， stratified by age （＜50， 50-59， 60-69， ≥70 years old） and AO subtypes （A1， A2， A3）. A multivariate logistic regression model was used to identify independent factors influencing treatment choice. ResultsOn 5-7 days after treatment， the surgical group had lower VAS scores than the TCM group， while 4-6 weeks after treatment， the TCM group showed lower VAS scores than the surgical group （P＜0.01）. In terms of radiographic indicators， except for the palmar tilt before treatment being higher in the surgical group than in the TCM group （P＜0.01）， there were no significant differences in palmar tilt， ulnar deviation， and radial height at other timepoints （P＞0.05）. Twelve weeks after treatment， the surgical group had a higher average Gartland-Werley score and the excellent rate than the TCM group （P＜0.01）. Subgroup analysis showed that in patients with A2 type DRF aged 50-59 and 60-69 years old， the excellent rates of Dienst and Gartland-Werley scores in the TCM group were higher than those in the surgical group （P＜0.05）. Multivariate logistic regression analysis revealed that age， palmar tilt， ulnar deviation， and the degree of swelling on the affected side were independent factors influencing the choice of treatment （P＜0.05）. ConclusionBoth TCM manipulative reduction combined with small splint fixation and surgical treatment for type A DRF can achieve good therapeutic effects. TCM manipulative reduction combined with small splint fixation has certain advantages in medium- and long-term pain relief， especially in elderly patients， where wrist joint function recovery is more stable. Age， palmar tilt， ulnar deviation， and swelling degree are the main factors influencing the treatment choice.

ObjectiveTo observe the clinical efficacy and radiographic outcomes of manipulative reduction combined with small splint fixation in the treatment of distal radius fractures. MethodsThe clinical data of 1051 patients with distal radius fractures were retrospectively collected from five hospitals included in the Jiangsu Diagnosis and Treatment Data Platform for Traditional Chinese Medicine（TCM） Dominant Diseases. Propensity score matching at a 1∶4 ratio was applied， resulting in 580 cases selected for final analysis， which comprised 448 patients in the TCM group（manipulative reduction plus small splint fixation） and 132 in the surgical treatment group（open reduction and internal fixation）. Each group was further stratified into type A， B， and C subgroups based on AO fracture classification. Radiographic indicators including palmar tilt， radial inclination， and radial height were compared between groups before treatment and 1 day， 1 week， and 4-6 weeks after treatment， and pain visual analog scale（VAS） scores before treatment and 1 week and 4-6 weeks after treatment were also compared. Wrist joint function was assessed 12 weeks after treatment， using the Dienst wrist function score and the Gartland and Werley（G-W） wrist function score. Additionally， the radiographic indicators at different timepoints and the 12-week wrist function levels were compared between groups across different fracture types. ResultsNo statistically significant difference was observed in radiographic indicators and VAS scores at all timepoints before and after treatment， as well as wrist joint function grades assessed by the Dienst score and the G-W score at 12 weeks after treatment （P＞0.05）. Compared to those before treatment， both groups showed increased palmar tilt， radial inclination， and radial height 1 week and 4-6 weeks after treatment， and decreased VAS scores （P＜0.05）. Compared to those 1 week after treatment， both groups showed a decrease in palmar tilt， an increase in radial inclination and radial height， and a reduction in VAS score 4-6 weeks after treatment（P＜0.05）. In type A and B subgroups， the surgical treatment group had a higher radial inclination than the TCM group 4-6 weeks after treatment， while in the type C subgroup， a higher radial height was shown in the surgical treatment group than in the TCM group 4-6 weeks after treatment（P＜0.05）. In type C subgroup， there was significant difference between groups in the wrist joint function by G-W scores 12 weeks after treatment（P＜0.05）. ConclusionManipulative reduction combined with small splint fixation can maintain fracture alignment and alleviate pain in treating distal radius fractures， which achieves therapeutic outcomes comparable to surgical treatment. It is particularly suitable for type A and B fractures and can be considered an effective treatment option for distal radius fractures.

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: This prospective study evaluated the feasibility of chemical exchange saturation transfer (CEST) MRI for assessing disease activity in thyroid-associated ophthalmopathy (TAO). Materials and Methods: A total of 88 patients with active TAO, 76 with inactive TAO, and 30 healthy controls were enrolled. CEST MRI-derived magnetization transfer ratio (MTR) and MTR asymmetry (MTRasym) at 1 ppm, 2 ppm, and 3.5 ppm were calculated. Clinical data, MTR, and MTRasym values for the extraocular muscles (one representative muscle per eye, yielding two measurements per participant) were compared among the groups. Spearman’s correlation was used to examine associations between imaging parameters and the clinical activity score (CAS) in patients with TAO. Logistic regression analysis was used to identify independent associations between imaging parameters and disease activity in patients with TAO (active vs. inactive). Receiver operating characteristic (ROC) analysis was conducted to evaluate the diagnostic performance for discriminating active from inactive TAO. Results: Patients with active TAO showed lower MTR values (P < 0.001) and higher MTRasym (1 ppm), MTRasym (2 ppm), and MTRasym (3.5 ppm) (all P < 0.001) compared with those with inactive TAO. MTR was negatively correlated with CAS (r = -0.402; P < 0.001), while MTRasym (1 ppm), MTRasym (2 ppm), and MTRasym (3.5 ppm) were positively correlated with CAS (r = 0.369, 0.350, and 0.349, respectively;all P < 0.001). MTR and MTRasym (1 ppm) were independently associated with TAO activity. The areas under the ROC curve (AUCs) for MTR and MTRasym (1 ppm) in discriminating active from inactive TAO were 0.772 and 0.730, respectively. Combining MTR with MTRasym (1 ppm) significantly improved diagnostic performance compared with either parameter alone, achieving an AUC of 0.805 (P = 0.029 and 0.001). Conclusion MTR and MTRasym (1 ppm) were independently associated with TAO activity. Their combination further enhanced diagnostic performance in distinguishing active from inactive TAO, suggesting their potential as quantitative imaging biomarkers to guide treatment in patients with TAO.

Objective: To investigate the clinical characteristics, the types of unexpected antibodies, and their impacts on immunological risks among patients with different frequencies of cross-matching incompatibility, so as to propose corresponding solutions. Methods: Data of cross-matching incompatibility samples from 92 medical institutions during 2022 to 2024 were collected and divided into three groups based on the frequency of cross-matching. Statistical analysis was performed on disease types, distribution of hematologic diseases, alloantibody detection rates, and proportions of alloantibody types. Results: The 858 patients were divided into three groups based on the frequency of blood cross-matching incompatibility: ≥5 times (8.28%, 71/858), 2 to 4 times (28.21%, 242/858); 1 time (63.52%, 545/858). There was a clustered distribution of disease types in the ≥5 cross-matchings group, with 71.83% (51/71) of patients having tumors or hematologic and hematopoietic diseases. In contrast, the disease types in the 2 to 4 cross-matchings and 1 cross-matching groups were more diverse. An analysis of 249 patients with hematologic diseases found that multiple myeloma was the most common disease in all three groups, accounting for 31.43% (11/35), 35.37% (29/82), and 37.88% (50/132) respectively. In the ≥5 cross-matchings group, myelodysplastic syndrome (14.29%, 5/35) and thalassemia (14.29%, 5/35) were the second most common diseases. In contrast, in the 2 to 4 cross-matchings group and 1 cross-matching group, autoimmune hemolytic anemia was the second most common disease, with prevalence rates of 20.73% (17/82) and 24.24% (32/132), respectively. Alloantibodies were detected in 54.66% of the patients, with antibodies against Rh blood group being most frequent (>50%) in all three groups. The detection rates of alloantibodies/alloantibodies with coexisting autoantibodies decreased across groups: the ≥5 cross-matchings group (70.42%, 50/71) > the 2 to 4 cross-matchings group (54.96%, 133/242) > the 1 cross-matching group (52.48%, 286/545). Conclusion: The risk of alloantibody production increases in patients with multiple cross-matching incompatibilities, especially in those with tumors or hematologic diseases. For handling of cross-matching incompatibility cases, it is recommended to optimize the cross-matching process, implement individualized transfusion plans, and enhance the technical capabilities of clinical transfusion departments and blood group reference laboratories to ensure the safety and effectiveness of transfusions.

Objective To evaluate the gap between China's top-tier medical institutions and top-tier international medical institutions,and to provide references for the construction of first-class medical science discipline in China.Methods Using globally recognized rankings of medical institutions,we selected 24 top-tier international medical institutions and 11 top-tier Chinese medical institutions.Publicly available,general,and comparable data on indicators were collected to analyze the performance and gaps between top-tier international and Chinese medical institutions in human resources development,talent cultivation,scientific research,social services,and discipline construction.Results In the field of medicine,the largest gap between top-tier international and Chinese medical institutions was in high-level talent.Specifically,the average numbers of individuals who are Clarivate Analytics'Highly Cited Researchers,who are Nobel Prize laureates in Physiology or Medicine,and who serve on advisory boards or editorial boards of top medical journals,and who rank among the Top 2 000 Medicine Scientists were 1.00,0.09,0.45 and 4.00,respectively,among top-tier Chinese medical institutions,while those of the top-tier international medical institutions were 131.46,118.25,9.72,and 6.76 times,respectively,those of the Chinese medical institutions.The second largest gap was in social services and medical innovation.The average proportion of industrial collaboration papers and the number of clinical trials of China's top-tier medical institutions were 1.51％and 1 851,respectively,while those of international top-tier medical institutions were 3.62 and 1.87,times,respectively,those of top-tier Chinese medical institutions.However,the average number of(untranslated)patents held by top-tier international medical institutions was only 15％ of that of China's top-tier medical institutions.The third largest gap was in scientific research.The average number of papers published in New England Journal of Medicine,Journal of the American Medical Association,The Lancet,and British Medical Journal,the percentage of hot papers in papers included in Web of Science,the percentage of highly cited papers,the percentage of international collaboration papers,the total number of citations per paper,category normalized citation impact(CNCI),and the number of publications of top-tier Chinese medical institutions were 78,0.03％,1.39％,22.55％,19.61,1.26,30 706,while those of the top-tier international medical institutions were 6.96,2.66,2.57,2.15,1.83,1.58 and 1.54 times those of the Chinese medical institutions,respectively.However the average percentage of zero-citation papers of top-tier international medical institutions was only 71％of that of China's top-tier medical institutions.Furthermore,in discipline development,the average overall scores of the Times Higher Education(THE)and QS rankings for medicine-related disciplines of top-tier Chinese medical institutions were 72.84 and 69.30,respectively,while those of top-tier international medical institutions were 1.38 and 1.21 times those of the Chinese medical institutions.However,in terms of talent cultivation,the average number of students of China's top-tier medical institutions was 10724,which is roughly double that of international institutions.Conclusion Currently,China's top-tier medical institutions are still in a basic stage that emphasizes the quality of talent cultivation and medical services.There is considerable room for development and potential for catching up in multiple aspects,especially in high-level talent,medical research,and innovation.It is recommended that the construction experience of top-tier international medical institutions should be fully utilized to build China's first-class medical science discipline.

Objective To explore the application value of CT classification of lumbar spinal stenosis(LSS)in selecting endoscopic decompression surgery approach.Methods The clinical data and CT imaging materials of 300 patients with LSS,who received percutaneous endoscopic decompression surgery from March 2018 to December 2024 were selected from Hengshui Municipal People's Hospital in Hebei(Halison International Peace Hospital),were retrospectively analyzed.Preoperative CT scan was performed in all patients.Taking endoscopic classification as the golden standard,the consistency between CT classification results and endoscopic classification results was assessed by Kappa consistency analysis.The effect of surgery of different approaches for percutaneous endoscopic decompression surgery was compared.Results CT diagnostic classification of type Ⅰ LSS was obtained in 87 patients(among them 3 patients with type Ⅲ LSS were misdiagnosed as type Ⅰ LSS),type Ⅱ LSS in 141 patients and type ⅢLSS in 72 patients,the total diagnostic accuracy rate was 97.67％.Using endoscopic classification as the gold standard,the Kappa values for CT diagnosis of type Ⅰ,type Ⅱ and type Ⅲ were 0.975,1.000 and 0.973,respectively.According to the CT classification results,all 300 patients successfully selected different surgical approaches to complete the surgery,and their clinical symptoms were significantly relieved without significant complications.After surgery,the Oswestry disability index(ODI)and visual analogue scale(VAS)scores of leg/lower back in patients with different LSS types showed a decreasing trend(P＜0.05).After treatment,the total frequency of taking non-steroidal drugs was significantly lower than that before surgery(P＜0.05).Conclusion The classification of LSS is highly consistent between CT scan and endoscopic examination,which is of great value for the selection of percutaneous endoscopic decompression surgery approach.

Objective To investigate the current status of breastfeeding motivation in early post-partum women and analyze the influencing factors of breastfeeding motivation.Methods A conven-ience sampling method was used to select 205 hospitalized women within 48 to 72 hours postpartum as the study subjects.The women were surveyed using a general information questionnaire,a breastfeed-ing motivation scale,a breastfeeding knowledge questionnaire,and a short-form scale for breastfeed-ing self-efficacy.Multiple linear regression analysis was conducted to explore the influencing factors of breastfeeding motivation among the women.Results The average score for autonomous motivation to-wards breastfeeding among 205 women was(49.94±7.62),and the average score for controlled mo-tivation was(23.76±3.59).The results of multiple linear regression analysis showed that age,par-ticipation in breastfeeding-related courses during pregnancy,planned duration of breastfeeding,skill dimension score of the short-form scale for breastfeeding self-efficacy,and total score on the breast-feeding knowledge questionnaire were influencing factors for the autonomous motivation score towards breastfeeding(P＜0.05);participation in breastfeeding-related courses during pregnancy,skill di-mension score on the short-form breastfeeding self-efficacy,and total score on the breastfeeding knowledge questionnaire were influencing factors for the controlled motivation score towards breast-feeding(P＜0.05).Conclusion The level of breastfeeding motivation in early postpartum women needs to be improved.Healthcare providers should focus on maternal age and planned duration of breastfeeding,strengthen breastfeeding knowledge education,and enhance maternal breastfeeding self-efficacy to improve maternal breastfeeding motivation and breastfeeding rates.
