With the rapid advancement of medical technology and the increasing complexity of clinical environments, competence in clinical ethical decision-making has become an indispensable core competency for exemplary physicians. However, traditional medical ethics education has long been confronted with the persistent challenges of theory-practice dissociation and the disconnect between pedagogical settings and clinical realities. Thus, how to construct a "Clinical Ethics" curriculum that aligns with the objectives of training high-caliber medical professionals has emerged as a critical and challenging issue in current medical education reform. To effectively address this challenge, the Office of Education at Peking University Third Hospital, since 2021, has assembled a multidisciplinary "Clinical Ethics" teaching and management team comprising faculty from Peking University School of Humanities and key clinical specialists from the hospital. In 2022, the "Clinical Ethics" elective course was formally launched for fourth-year students in the eight-year MD program who had completed coursework in "Medical Ethics" and organ-system-based curricula, with the aim of exploring and operationalizing a pre-clinical ethics education model tailored for senior medical students. The course employs a modular instructional design encompassing "theoretical review-case-based deliberation-clinical workshop", which effectively facilitates the deep integration of medical humanities with clinical practice.Following four years of iterative refinement through the "plan-act-observe-reflect" cycle, the course has demonstrated positive outcomes in enhancing students' ethical awareness and decision-making capabilities, and has preliminarily established a sustainable collaborative mechanism among the multidisciplinary faculty team. This article systematically delineates the course development background, pedagogical model and methodological innovations, and the multidisciplinary collaborative framework, alongside reflections and summaries based on implementation outcomes, with the intent of providing references for the future development of "Clinical Ethics" curricula.

Pituitary stalk interruption syndrome(PSIS) typically manifests initially as short stature due to growth hormone deficiency(GHD). Untreated chronic GHD may induce metabolic disturbances, leading to non-alcoholic fatty liver disease with rapid progression to liver cirrhosis. Liver cirrhosis can subsequently cause hepatopulmonary syndrome, resulting in hypoxemia and dyspnea. This article reports a case of a young male presenting with short stature, dyspnea, liver cirrhosis, and hepatopulmonary syndrome, ultimately diagnosed with PSIS. Following recombinant human growth hormone(rhGH) and other hormonal replacement therapies, the patient exhibited improvement in hepatic steatosis and fibrosis, with alleviation of dyspnea. Through analysis of this case, we provide clinical insights for diagnosing and managing cirrhosis and hepatopulmonary syndrome in such patients, highlighting that early diagnosis and timely initiation of rhGH replacement therapy can improve prognosis and quality of life.

Objective To compare the predictive value of ORBIT score and HAS-BLED score for bleeding risk after warfarin anticoagulation following heart valve replacement. Methods The clinical data of 304 patients who underwent heart valve replacement and required warfarin anticoagulation therapy were retrospectively analyzed. The patients were stratified and grouped based on the ORBIT score and HAS-BLED score. The correlation between risk stratification based on different scores and postoperative bleeding events during warfarin anticoagulation was analyzed. The consistency of risk stratification between the two scoring methods and their predictive value for bleeding events were compared. Results Among 304 patients, there were 32 bleeding patients and 272 non-bleeding patients. The postoperative ORBIT and HAS-BLED scores of the bleeding patients were higher than those of non-bleeding patients(P < 0.05). The bleeding risk of medium and high-risk patients based on the ORBIT score was 6.092 (95%CI, 2.694 to 13.775) times and 9.373 (95%CI, 1.465 to 59.943) times higher than that of low-risk patients, respectively. The bleeding risk of medium and high-risk patients based on the HAS-BLED score was 3.750 (95%CI, 1.383 to 10.166) times and 14.250 (95%CI, 5.489 to 36.995) times higher than that of low-risk patients, respectively. The analysis of the receiver operating characteristic curve showed that the area under the AUC (95%CI, 0.589 0.698 9) of ORBIT score for predicting the risk of postoperative warfarin anticoagulation bleeding was 0.646 (95%CI, 0.589 to 0.699), with a sensitivity of 46.88% and a specificity of 87.87%, and an optimal cutoff value of 3 points. The AUC of HAS-BLED score predicting the risk of postoperative anticoagulation bleeding with warfarin was 0.768 (95%CI, 0.717 to 0.814), with a sensitivity of 75.00% and a specificity of 69.85%, and an optimal cutoff value of 2 points. The Delong test results showed that there was a statistically significant difference in AUC between the two scores (D=0.122; 95%CI, 0.001 to 0.245; Z=1.962; P < 0.05). Conclusion Both ORBIT score and HAS-BLED score have certain predictive value for bleeding risk during warfarin anticoagulation after heart valve replacement, but the predictive efficiency of HAS-BLED score is better.

Objective:To evaluate the effectiveness,safety and economics of absorbable drug-eluting coronary stent systems using rapid health technology assessment tools,and to provide evidence-based basis for rational use for clinicians use and expert evaluation.Methods:A computer search was performed on PubMed,CNKI,Wanfang,VIP and other databases from 1 January 2014 to 1 January 2023 for relevant literature on patients with coronary artery disease who were treated with coronary artery stent interventional surgery.The 210 collected literatures were screened and extracted according to the inclusion and exclusion criteria,and the literature quality evaluation was carried out.The extracted data related to the intravascular thrombosis rate,myocardial infarction rate,cardiac mortality rate,all-cause mortality rate,target lesion revascularization rate and intravascular adverse event incidence of absorbable drug-eluting coronary stents and drug-eluting coronary stents were meta-analyzed by Revman5.4 software.Results:7 studies were ultimately included in the comparative study of absorbable drug-eluting coronary stents and drug-eluting coronary stents.The thrombosis rate,all-cause mortality rate and intravascular adverse event rate of absorbable drug-eluting coronary stents were lower than those of drug-eluting coronary stents,and the difference was statistically significant(Z=2.16,1.89,2.22,P＜0.05).There were no statistically significant difference in the myocardial infarction rate,cardiac mortality rate and target lesion revascularization rate between absorbable drug-eluting coronary stents and drug-eluting coronary stents(P＞0.05).Conclusion:There was no significant difference in safety and efficacy between absorbable drug-eluting coronary stents and drug-eluting coronary stents.In terms of economy,the cost of absorbable drug-eluting coronary stents is significantly higher than that of drug-eluting coronary stents,and patients can choose stents according to their own economic conditions and other actual conditions.

Objective:To determine the motion detection uncertainty of the real-time CybeRay ? imaging system and patient intrafractional motion with thermoplastic mask-based immobilization. Methods:Real-time CybeRay ? imaging system was used for irradiation and treatment for head phantom and patients with brain tumors. All patients were immobilized with thermoplastic masks. Real-time imaging was delivered using kilovoltage projection images during radiotherapy. The detected patient motion data was collected from 5 head phantom measurements and 27 treatment fractions of 9 brain tumor patients admitted to Kaifeng Cancer Hospital. The accuracy and uncertainty of the motion monitoring system were determined. Results:The mean and standard deviation (SD) of the detected motion in the X, Y, and Z directions for phantom were (-0.02±0.41) mm, (-0.05±0.22) mm and (0.01±0.35) mm, respectively. The detected motion in the X, Y and Z directions for patents were (-0.13±0.48) mm, (-0.05±0.48) mm and (0.11±0.36) mm, respectively. After removing the motion detection uncertainty, the actual intrafractional motion of patients were (-0.11±0.25) mm, (0±0.43) mm and (0.10±0.08) mm in three directions, respectively. Conclusions:The uncertainty of real-time imaging-based motion monitoring system of CybeRay ? is less than 0.5 mm. It is feasible to apply thermoplastic masks for brain tumor patients in clinical practice, which can provide steady immobilization and limit the SD of patient intrafractional motion within 0.5 mm. Real-time imaging-based motion monitoring system of CybeRay ? is accurate for patient motion monitoring during frameless stereotactic radiosurgery/radiotherapy.

Objective:To explore the role of continuous renal replacement therapy (CRRT) combined with extracorporeal carbon dioxide removal (ECCO 2R) in the treatment of children with respiratory failure. Methods:The clinical data of 12 children with respiratory failure who were treated with CRRT+ECCO 2R in PICU of Jinan Children's Hospital from July 2020 to August 2022 were collected and analyzed retrospectively. The outcomes and the external pipeline usage of the patients were observed, and the blood gas analysis and ventilator parameters before 1 h and after 1, 6, 12 and 24 h of the treatment were compared by one-way ANOVA with LSD post hoc correction. Results:Six patients successfully withdrew from CRRT+ECCO 2R and mechanical ventilation, three patients were transferred to ECMO treatment. Three cases died after voluntary withdrawal of treatment, and two cases died due to treatment failure. The mortality rate was 41.7%. After continuous treatment of CRRT+ECCO 2R for 15 to 112 h, two cases experienced extracorporeal circuit obstruction. After 1 h of treatment, PaCO 2 decreased from (64.67±24.4) mmHg to (49.42±15.54) mmHg, pH increased from (7.28±0.20) to (7.38±0.11), FiO 2 decreased from (0.85±0.13) to (0.78±0.15), PC decreased from (19.42±4.34) cmH 2O to (17.75±4.00) cmH 2O. After 24 h of treatment, PaCO 2 decreased to (39.2±5.55) mmHg, pH increased to (7.41±0.04), FiO 2 decreased to (0.46±0.11), and PC decreased to (13.8±3.36) cmH 2O, and the differences were statistically significant compared with before treatment ( P < 0.05). Conclusions:The combination of CRRT and ECCO 2R therapy can safely substitute for partial lung ventilation/perfusion function, and play a role in protecting right heart function and improving lung-kidney interaction. It can be considered as an option for extracorporeal respiratory, circulatory, and renal support, and consequently has broad prospects.

Objective:This paper examines the access control mechanisms of a big data platform and explores its integration with the ChatGPT artificial intelligence platform for nursing management. The aim was to pilot a self-monitoring and follow-up big data platform for valve disease patients in the Northeastern region of China and assess its effectiveness, providing healthcare professionals with a more practical follow-up tool.Methods:Convenience sampling was used to select 32 patients who underwent mechanical valve replacement surgery or postoperative follow-up at the affiliated hospital of North Sichuan Medical College between January and October 2022 by a retrospective study, were taking oral warfarin anticoagulant therapy, and were willing to use the platform. Based on their platform usage data from November to December 2022, the 32 patients were divided into two groups according to their INR compliance rates: a high compliance group (16 patients) and a low compliance group (16 patients). Evaluate the operational effectiveness of the platform and its impact on patient anticoagulation efficacy based on its usage frequency and INR value compliance rate.Results:The number of login times and INR values written by patients in the high-standard-rate group were (11.31 ± 3.38) and (7.00 ± 1.63) times respectively, which were higher than those in the low-standard-rate group (9.44 ± 3.39) and (6.06 ± 1.88) times, the difference were not statistically significant (all P>0.05). The number of INR values written within the normal range and the number of occurrences of warning values by patients in the high-standard-rate group were (6.38 ± 1.50) and 1.00(0, 2.00) times, which were different than that in the low-standard-rate group (4.05 ± 1.57) and 2.00(2.00, 3.50) times, the differences were statistically significant ( t = 4.26, Z = - 2.22, P<0.05). Conclusions:The self-monitoring and follow-up big data platform for patients after artificial mechanical valve replacement equipped with ChatGPT can optimize and standardize the nursing follow-up workflow, improve nursing work efficiency, reduce the workload of medical staff. At the same time, it provides a better self-management platform for patients after artificial mechanical valve replacement. Assist patients in monitoring INR values and predicting possible changes in their condition, providing corresponding warnings and recommendations helps patients better participate in self-anticoagulation management, and improves the quality of life of patients.
