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.
2.Generation mechanism, practical dilemmas, and promotion path for building a harmonious doctor-patient relationship from the perspective of intersubjectivity
Chinese Medical Ethics 2026;39(1):78-84
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 analyze the application effects of artificial intelligence (AI) software and Mimics software in preoperative three-dimensional (3D) reconstruction for thoracoscopic anatomical pulmonary segmentectomy. Methods A retrospective analysis was conducted on patients who underwent thoracoscopic pulmonary segmentectomy at the Second People's Hospital of Huai'an from October 2019 to March 2024. Patients who underwent AI 3D reconstruction were included in the AI group, those who underwent Mimics 3D reconstruction were included in the Mimics group, and those who did not undergo 3D reconstruction were included in the control group. Perioperative related indicators of each group were compared. Results A total of 168 patients were included, including 73 males and 95 females, aged 25-81 (61.61±10.55) years. There were 79 patients in the AI group, 53 patients in the Mimics group, and 36 patients in the control group. There were no statistical differences in gender, age, smoking history, nodule size, number of lymph node dissection groups, postoperative pathological results, or postoperative complications among the three groups (P>0.05). There were statistical differences in operation time (P<0.001), extubation time (P<0.001), drainage volume (P<0.001), bleeding volume (P<0.001), and postoperative hospital stay (P=0.001) among the three groups. There were no statistical differences in operation time, extubation time, bleeding volume, or postoperative hospital stay between the AI group and the Mimics group (P>0.05). There was no statistical difference in drainage volume between the AI group and the control group (P=0.494), while there were statistical differences in operation time, drainage tube retention time, bleeding volume, and postoperative hospital stay (P<0.05). Conclusion For patients requiring thoracoscopic anatomical pulmonary segmentectomy, preoperative 3D reconstruction and preoperative planning based on 3D images can shorten the operation time, postoperative extubation time and hospital stay, and reduce intraoperative bleeding and postoperative drainage volume compared with reading CT images only. The use of AI software for 3D reconstruction is not inferior to Mimics manual 3D reconstruction in terms of surgical guidance and postoperative recovery, which can reduce the workload of clinicians and is worth promoting.

For patients with edentulous maxillae, creating a prosthetic treatment plan involves considering anatomical factors, aesthetics, the patient’s financial situation, and oral hygiene capabilities. In this case, CAD-CAM technology was used to accurately plan implant placements for a full arch fixed restoration based on the design of the final prosthesis. A customized surgical guide ensured precise implant placement and a provisional restoration was created using CAD-CAM. The definitive prosthesis was then created based on the second provisional restoration that has been previously used and adjusted by the patient. This approach achieved an excellent functional and aesthetic outcome, highlighting the benefits of digital approach and its potential for further clinical applications.

For patients with a few remaining abutment teeth, traditional removable partial dentures and implant-supported fixed prostheses are common treatment options.However, removable dentures often struggle to provide stability, especially as bone resorption occurs over time. Implant-supported fixed prostheses offer longterm stability but are costly and affected by anatomical and medical factors. A newer option is implant-assisted removable partial dentures, which use a minimal number of implants combined with a surveyed crown. This approach enhances support, retention, and stability while reducing financial and surgical burdens. It also improves the prognosis of the remaining teeth, increases patient satisfaction, and enhances masticatory function, making it a promising alternative to conventional removable dentures.

Primary cholangiocarcinoma is a rare bile duct epithelial neoplasm that can present with atypical clinical manifestations, complicating its diagnosis. A 62-year-old male showed symptoms suggestive of a complicated hepatic cyst that was later identified as intrahepatic cholangiocarcinoma. The patient presented with abdominal discomfort without fever. Imaging revealed a large cystic lesion in the liver. Despite the initial treatment for a presumed abscess, a biopsy confirmed cholangiocarcinoma. This case highlights the diagnostic challenge of distinguishing between benign complicated hepatic cysts and malignancies, particularly when typical markers of infection are absent. Early biopsy and vigilant assessments are crucial in such presentations to avoid a delayed diagnosis and initiate appropriate treatment.

Hepatic tuberculosis, typically associated with miliary tuberculosis, can occasionally present as localized liver lesions. This case report describes a 77-year-old male presenting with persistent abdominal pain and fever, following an endoscopic retrograde cholangiopancreatography for bile duct sludge removal. Subsequent computed tomography revealed focal liver lesions. Despite initial treatment with antibiotics for a suspected inflammatory liver abscess, his condition did not improve. A liver biopsy was performed, revealing caseous granulomas, and the tuberculosis polymerase chain reaction result was positive. The patient was diagnosed with primary hepatic tuberculosis, which later disseminated. Oral anti-tuberculosis therapy was initiated and is currently being closely monitored. This case emphasizes the importance of considering hepatic tuberculosis in the differential diagnosis of liver lesions, particularly in cases involving cholestatic liver function tests, and persistent symptoms unresponsive to conventional antibiotics.

Helicobacter pylori causes gastric cancer and peptic ulcers, and eradication therapy can reduce the incidence of cancer in high-risk groups. In Korea, discrepancies between the reimbursement criteria and clinical guidelines create clinical challenges. This study investigated the perceptions and practices of experts regarding H. pylori testing during upper gastrointestinal endoscopy and any subsequent eradication therapy. An anonymous 8-question survey was conducted among 51 experts attending the 2024 Korean College of Helicobacter and Upper Gastrointestinal Research Summer Workshop. Only 2% of the experts tested all patients. Testing was performed in 54% of patients with a family history of gastric cancer, 32% of those with atrophic gastritis, 42% of those with dyspeptic symptoms, and 62% of those with iron-deficiency anemia. Among patients with suspected infections (based on endoscopic findings) and eligible for selective reimbursement, 82% underwent H. pylori testing. Age did not influence testing decisions for 60% of the experts, and 57% considered factors other than age when deciding on eradication therapy. The practices of the experts varied depending on the patient’s clinical condition and economic burden. Aligning clinical guidelines with the reimbursement criteria is necessary to reduce confusion and ensure appropriate patient care.

Objectives:
Although non-ampullary duodenal neuroendocrine tumors (NADNETs) are rare neoplasms, their incidence has been increasing. In this study, we aimed to analyze the long-term outcomes of patients with NADNETs who underwent endoscopic resection (ER) or surgery.
Methods:
This retrospective study included 55 adults (aged 26–78 years) diagnosed with NADNETs between 2009 and 2022 at Seoul National University Hospital. We categorized the patients into 3 groups: 21 underwent ER, 28 underwent surgical resection, and 6 had no detectable residual tumors after the initial biopsy during the follow-up period. Continuous data were examined using the Mann–Whitney U or Kruskal–Wallis tests, and categorical variables were analyzed using the χ2 or Fisher’s exact tests.
Results:
A total of 21 patients, with a mean tumor size of 9.2±5.3 mm, underwent successful ER. After ER, three patients experienced perforation (14% [3/21]); two underwent primary repair surgery, and one recovered with conservative treatment. The mean tumor size of 28 patients who underwent surgical resection was 13.9±6.7 mm. There were no cases of postoperative bleeding or perforation; however, four patients experienced ileus and required prolonged hospital stays. The median follow-up periods for patients who underwent ER, surgical resection, and removal after the initial biopsy were 42, 48, and 42.5 months, respectively. During the follow-up period, no recurrence was observed in any group.
Conclusions
Recurrence-free survival in patients undergoing ER for NADNETs, with an endoscopically measured size of approximately 10 mm, was comparable to that of patients undergoing surgical resection. However, ER carried a relatively high risk of perforation due to the challenging anatomical access and thin duodenal wall.
