Building a harmonious doctor-patient relationship reflects the people’s expectations and society’s aspirations. It is an important factor related to the well-being of the population and the implementation of the healthy China strategy. The theory of intersubjectivity focuses on responding to the relationship between subjects. Based on the principles of interactivity， liveliness， and dialogue rationality， it highlights equal interaction， mutual understanding， and effective dialogue between subjects. Applying the intersubjectivity theory to the construction of a harmonious doctor-patient relationship can help to break the behavioral paradigm of the doctor-patient subject-object dichotomy， highlighting the true freedom of the doctor-patient dual subjects. From the perspective of intersubjectivity， a harmonious doctor-patient relationship is generated from intersubjective behavior， facilitated by pre-understanding between subjects， and realized through effective dialogue between subjects. In the real world， the obfuscation of subjective rationality， the division of cognitive structure， and the uneven demands of interest between doctors and patients eliminate the inherent mechanisms of a harmonious doctor-patient relationship. This leads to multiple practical dilemmas， such as a “subject-object” one-dimensional thinking mode， a “professional-life” structural cognitive difference， and “reason-sensibility” dislocation dialogue styles presented between doctors and patients. Promoting the transformation of doctor-patient interactive thinking form， the integration of their communication perspectives， and the enhancement of dialogue skills can help to achieve mutual understanding in cognition， mutual trust and empathy in emotions， and harmonious alignment in actions. Therefore， to address these dilemmas， this paper proposed a path by embedding intersubjectivity theory， strengthening bidirectional doctor-patient interaction， emphasizing doctor-patient illness narratives， bridging doctor-patient cognitive differences， focusing on improving subjective competencies， and enhancing doctor-patient humanistic care.

Objective: To explore the psychological connection between non-suicidal self injury (NSSI) behavior and childhood trauma among vocational college students, thereby informing the optimization of mental health services. Methods: From June to July 2025, 18 students with NSSI behavior and childhood trauma were recruited from two vocational colleges in Heze City for semi structured interviews. Data were analyzed using Colaizzi s seven step analysis method for coding and thematic extraction. Results: Four core themes and ten subthemes were identified. Childhood trauma drove NSSI behavior through four interrelated psychological pathways, containing a cognitive pathway for internalization of traumatic beliefs and self punishment, an emotional pathway for dysregulation of traumatic emotions and compensatory behaviors, a somatic behavioral pathway for somatization and reenactment of traumatic memories, and an interpersonal pathway for impaired trust and isolation based coping. These pathways intertwined and reinforced each other, forming a psychological network underlying NSSI behavior. Conclusions Childhood trauma serves as a core risk factor for NSSI, establishing NSSI behavior through "intertwined cognitive, emotional, somatic and interpersonal" pathways. Effective intervention should adopt an integrated approach incorporating cognitive restructuring, emotional regulation training, trauma recovery, and the social support reconstruction.

Objective To explore the clinical efficacy of plasma exchange (PE) and double-filtration plasmapheresis (DFPP) pretreatment regimens for high-titer ABO-incompatible kidney transplantation (ABOi-KT). Methods A retrospective analysis was conducted on 31 cases of ABOi-KT with a follow-up period ≥1 year admitted to Zhongshan Hospital Affiliated to Fudan University from April 2016 to August 2025. The efficacy differences between the PE combined with rituximab (RTX) + oral triple immunosuppressive regimen and the DFPP combined with RTX + oral triple immunosuppressive regimen were compared and analyzed. The titers of blood group antibodies and serum creatinine levels before and after the operation were monitored. The survival curves and cumulative risk occurrence curves were plotted using the Kaplan-Meier method. The survival rates of recipients and transplanted kidneys and the occurrence of complications were analyzed. Results Both the PE regimen and the DFPP regimen may effectively reduce the preoperative blood group antibody titer of the recipients to ≤1∶16. The one-year survival rate of the recipients and the transplanted kidneys both reached 100% after the operation. The postoperative serum creatinine levels of recipients who received the DFPP regimen were lower and more stable. There was no statistically significant difference in the incidence of complications between the two regimens during the same follow-up period. Conclusions Both the PE and DFPP regimens are effective pretreatment regimens for ABOi-KT. The DFPP regimen has more advantages in reducing treatment operations, lowering drug dosage and maintaining the stability of postoperative renal function. For recipients with a high initial antibody titer (≥ 1∶32), individualized determination of the number and frequency of plasma processing for pretreatment may achieve ideal therapeutic effects.

ObjectiveIn the context of the digital transformation of education, this study aims to construct a triadic interactive teaching model for surgical animal surgery in clinical medicine using modern information technology. It explores the effectiveness of different teaching methods in improving students' practical skills, aseptic awareness, and teamwork abilities, providing a reference for the reform of clinical practice education. MethodsA quasi-experimental research design was adopted. A total of 80 students from the eight-year clinical medicine program at Nanjing University were selected, including the Class of 2020 (control group, n=40) and the Class of 2021 (experimental group, n=40). The control group received traditional teaching methods, while the experimental group implemented the "Teacher-Student-AI" triadic interactive teaching model. This model utilized a smart teaching platform for personalized pre-class preparation , as well as data-driven post-class review and feedback throughout the entire teaching process. The "assessment indicators and scoring criteria for the surgical animal surgery course" were used to evaluate teaching effectiveness, with independent samples t-tests used for statistical analysis. ResultsPre-course assessments revealed no statistically significant differences in baseline theoretical knowledge or practical skills between the two groups (P>0.05). Upon completion of the course, the experimental group achieved higher scores than the control group across three key dimensions: practical skills (47.98±1.34 vs 46.92±2.51, P=0.022), aseptic awareness (17.84±1.16 vs 16.94±2.29, P=0.029), and teamwork (16.82±1.44 vs 15.95±1.22, P=0.004). However, no statistically significant difference was observed in the scores for humane care awareness between the two groups (8.24±0.70 vs 8.16±0.53, P=0.589). ConclusionThe AI-based triadic interactive teaching model can, to some extent, address the limitations of traditional surgical animal surgery education. It plays a positive role in enhancing medical students' surgical skills, aseptic awareness, and collaborative abilities. This model facilitates the transition from traditional to personalized teaching and offers a practical framework for the digital reform of clinical practice education.

Traditional Chinese medicine and its bioactive components have garnered increasing attention as potential therapeutic options for allergic asthma. By targeting the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway, these natural compounds exhibit unique advantages in multilevel immunomodulation and inflammation suppression compared with single-target synthetic drugs. Accumulating pharmacological evidence supports their capacity to restore pathway homeostasis, positioning them as promising candidates for complementary strategies in asthma management. Allergic asthma, a heterogeneous respiratory disorder affecting approximately 150 million individuals worldwide, arises from a complex interplay of genetic predisposition, environmental exposures, and lifestyle factors. Its pathological progression is marked by aberrant activation of the PI3K/AKT signaling cascade, with the mechanistic target of rapamycin serving as a key downstream regulatory node. This evolutionarily conserved pathway orchestrates fundamental cellular processes that contribute to three hallmark pathological features of allergic asthma: chronic airway inflammation, structural remodeling of the bronchial architecture, and airway hyperresponsiveness. This review has 3 primary objectives: (1) to evaluate the role of the PI3K/AKT pathway in allergic asthma pathogenesis, (2) to analyze the molecular mechanisms of representative traditional Chinese medicine preparations and their active ingredients, and (3) to identify novel bioactive inhibitors derived from natural products. Collectively, these investigations provide a conceptual framework for the development of next-generation targeted therapies and for optimizing clinical management strategies for allergic asthma.

Objective:To construct a nomogram model for predicting the first pass effect (FPE) in mechanical thrombectomy for acute ischemic stroke with anterior circulation large vessel occlusion(AIS-LVO).Methods:Retrospectively controlled analyzed the clinical data of 146 patients with acute ischemic stroke due to anterior circulation large vessel occlusion who underwent mechanical thrombectomy in the Affiliated Suzhou Hospital of Nanjing Medical University (Suzhou Municipal Hospital) from January 2020 to January 2025. Among the 146 patients, there were 76 males and 70 females, with an age ranged from 39 to 88 years old and a median age of 75 years. According to whether FPE was obtained during the operation, the patients were divided into the FPE group ( n=47)and the non-FPE group ( n=99). The clinical data between the two groups were compared, and those with statistically significant differences ( P<0.05) throngh univariate analysis were included in the multivariate Logistic regression analysis to screen the independent risk factors affecting FPE and establish a nomogram model. The efficiency, goodness of fit and benefit of the established model were tested through internal validation. Results:The results of univariate analysis showed that there were statistically significant differences in the history of essential hypertension, clot burden score (CBS), internal carotid artery tortuosity, hyperdense vessel sign, serum D-dimer value, serum lymphocyte count, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and systemic immune-inflammation index (SII) between the two groups ( P<0.05). Multivariate Logistic regression analysis showed that the history of essential hypertension ( OR=0.25, 95% CI: 0.09-0.67, P=0.006), high clot burden with CBS ≤ 6 points ( OR=0.25, 95% CI: 0.10-0.66, P=0.005), internal carotid artery tortuosity ( OR=0.38, 95% CI: 0.15-0.98, P=0.044), high PLR ( OR=0.98, 95% CI: 0.97-0.99, P=0.005), and high D-dimer ( OR=0.35, 95% CI: 0.15-0.81, P=0.015) were all independent risk factors affecting FPE in mechanical thrombectomy for acute ischemic stroke with anterior circulation large vessel occlusion ( P<0.05). A nomogram prediction model was established based on the above risk factors. The verification results showed that the area under the curve was 0.836, the Hosmer-Lemeshow test showed that χ2=5.105, P=0.746, and the decision curve showed that when the threshold probability was in the range of 0.01 to 0.87, there was a higher net benefit value. Conclusion:The nomogram model established according to the patient′s history of essential hypertension, clot burden score, whether there is internal carotid artery tortuosity, PLR, and D-dimer can predict the probability of obtaining FPE in mechanical thrombectomy for acute ischemic stroke with anterior circulation large vessel occlusion.

Background: This study aimed to compare the intraoperative stability and early clinical outcomes of 40-mm diameter dual mobility (DM)-total hip arthroplasty (THA) with 36-mm ceramic head (large head) THA in active elderly patients with hip fractures. Methods: A prospective randomized controlled trial was conducted from May 2022 to December 2022. Inclusion criteria were as follows: age ≥ 60 years, displaced femoral neck fracture, Koval grade 1 or 2, planned 54-mm acetabular component, and over 1-year follow-up. Intraoperative stability tests were performed on all patients (internal rotation at 45°, 60°, and 90° of hip fracture). Functional outcomes (Harris Hip Score and University of California, Los Angeles [UCLA] Score) were evaluated at 6 weeks and 3 months postoperatively. Gait analysis using artificial intelligence (AI) techniques was conducted at 3 months postoperatively. Results: The study included 36 DM-THA patients (mean age, 69.6 ± 2.2 years; 44% women) and 37 large head THA patients (mean age, 69.6 ± 1.2 years; 64% women). No statistically significant differences were observed in functional outcomes and hip range of motion between the 2 groups. However, there was a significant difference in the gait speed and stance-swing phase of the large head THA group and the DM-THA group: the DM-THA group demonstrated superior gait speed (2.85 ± 0.83 kph vs. 2.04 ± 1.04 kph, p = 0.003) and higher stance phase ratios (operated side: 63.57% ± 3.82% vs. 48.19% ± 5.50%, p < 0.001; opposite side: 62.77% ± 2.27% vs. 49.93% ± 6.94%, p < 0.001). In the stability test at 90° of hip flexion, the DM-THA group had a measurement of 48.40° ± 5.17°, while the large head THA group had a measurement of 30.94° ± 2.98° (p = 0.012). Despite the lack of statistical significance, the intraoperative stability test showed the dislocation angle was notably different between the groups in the hip flexion position of 60° (51.60° ± 6.09° in the DM-THA group and 40.00° ± 2.80° in the large head THA group, p = 0.072). Conclusions Superior results were observed in the intraoperative stability test and early recovery of gait after DM-THA compared to large head THA. We believe that DM-THA can be a useful surgical option for THA in elderly patients with hip fractures.

Background: This study aimed to evaluate the degree of glenoid concavity restoration and its effect on surgical failure after arthroscopic bony Bankart repair for recurrent anterior shoulder instability with a bony Bankart lesion. Methods: Forty-one patients who underwent arthroscopic bony Bankart repair for recurrent anterior shoulder instability with a bony Bankart lesion were retrospectively evaluated. All patients underwent 3-dimensional computed tomography (3D-CT) preoperatively to evaluate the glenoid concavity using the bony shoulder stability ratio (BSSR). Bony fragments were incorporated to the anterior glenoid during arthroscopic stabilization procedure. All patients were reevaluated by 3D-CT at postoperative 1 year to assess the changes in the BSSR and the final glenoid bone defect size after bony Bankart repair. Clinical outcomes including surgical failure were evaluated at least 2 years after surgery. Results: The BSSR significantly increased after surgery (26.0% ± 14.0% preoperatively and 35.5% ± 13.2% postoperatively, p < 0.001). Preoperative glenoid bone defect size was 16.2% ± 8.1%, and bony Bankart fragment size was 11.3% ± 7.2%. Four patients (9.8%) had recurrent instability requiring revision surgery. In patients with surgical failure, the BSSR was not improved after surgery (18.2% ± 13.3% preoperatively and 23.1% ± 17.3% postoperatively, p = 0.24). In contrast, patients without surgical failure showed significantly improved BSSR after surgery (26.9% ± 14.0% preoperatively and 36.9% ± 12.2% postoperatively, p < 0.001).No significant differences were found in the final glenoid bone defect size (6.6% ± 5.9% in patients with surgical failure vs. 6.2% ± 5.7% in patients without surgical failure, p = 0.92) and bony Bankart fragment nonunion rate (0% in patients with surgical failure vs. 5.4% in patients without surgical failure, p = 0.99) between patients with and without surgical failure. Conclusions Glenoid concavity, as represented by the BSSR, improved after arthroscopic bony Bankart repair, and satisfactory restoration of the glenoid concavity led to successful clinical outcomes without surgical failure. The BSSR could be considered an important factor for predicting clinical outcomes after arthroscopic bony Bankart repair. However, further research including more contributing factors is needed to better analyze the impact of the BSSR on clinical outcomes.

Background: and Purpose: Amyloid-beta (Aβ) plaques are key in Alzheimer’s disease (AD), with Aβ positron emission tomography imaging enabling non-invasive quantification.To address regional Aβ deposition, we developed regional Centiloid scales (rdcCL) and commercialized them through the computed tomography (CT)-based BeauBrain Amylo platform, eliminating the need for three-dimensional T1 magnetic resonance imaging (MRI). Objective: We aimed to establish robust regional Aβ cutoffs using the commercialized BeauBrain Amylo platform and to explore the prevalence of subgroups defined by global, regional, and striatal Aβ cutoffs across cognitive stages. Methods: We included 2,428 individuals recruited from the Korea-Registries to Overcome Dementia and Accelerate Dementia Research project. We calculated regional Aβ cutoffs using Gaussian Mixture Modeling. Participants were classified into subgroups based on global, regional, and striatal Aβ positivity across cognitive stages (cognitively unimpaired [CU], mild cognitive impairment, and dementia of the Alzheimer’s type). Results: MRI-based and CT-based global Aβ cutoffs were highly comparable and consistent with previously reported Centiloid values. Regional cutoffs revealed both similarities and differences between MRI- and CT-based methods, reflecting modality-specific segmentation processes. Subgroups such as global(−)regional(+) were more frequent in non-dementia stages, while global(+)striatal(−) was primarily observed in CU individuals. Conclusions Our study established robust regional Aβ cutoffs using a CT-based rdcCL method and demonstrated its clinical utility in classifying amyloid subgroups across cognitive stages. These findings highlight the importance of regional Aβ quantification in understanding amyloid pathology and its implications for biomarker-guided diagnosis and treatment in AD.

Background: and Purpose: Mild cognitive impairment (MCI) is a transitional stage to dementia, Alzheimer’s disease being a major cause. Although amyloid beta-positive (Aβ+) MCI has been well-characterized, Aβ-negative (Aβ−) MCI has not. This study compared the comprehensive clinical and behavioral characteristics of Aβ+ and Aβ− MCI in a large multicenter cohort to better understand the heterogeneity of MCI, and to identify contributing factors to cognitive impairment. Methods: A total of 686 MCI participants were included. Aβ positivity was determined using Aβ positron emission tomography imaging with a direct conversion Centiloid cutoff value of 25.5. Standardized assessment and questionnaires were used to collect a wide range of clinical information, including vascular risk factors, cognition, daily living function, neuropsychiatric symptoms, and lifestyle behavior. Groups were compared using independent t-tests and χ2 tests. Results: Aβ+ participants (n=406) were older, predominantly female, and more likely to be ApoE4 carriers. In contrast, Aβ− participants (n=280) showed higher vascular risk factors, including diabetes, elevated body mass index, and higher C-reactive protein levels.Aβ+ participants exhibited worse global cognition and functional decline, with a higher prevalence of delusions and appetite disturbances. Meanwhile, Aβ− participants reported greater social engagement, but poorer sleep quality. Conclusions This study highlights the distinct clinical and lifestyle profiles of Aβ+ and Aβ− MCI, illuminating the heterogeneity of MCI and its underlying factors in the Korean population.
