ObjectiveTo investigate the current situation of mutual recognition for ethical review outcomes in multicenter clinical research across 10 contracting medical institutions in Guangdong Province， analyze existing issues and propose improvement recommendations， thereby promoting the standardized management of mutual recognition for ethical review outcomes in medical institutions. MethodsData from 381 multicenter clinical studies conducted in these 10 medical institutions from January 24 to October 31， 2024， were collected. Text visualization was performed using Python and the WordCloud library， and statistical analyses were conducted with SPSS 25.0. ResultsOf the 381 studies investigated， industry-sponsored clinical trials （ISTs） accounted for 51.71%， while investigator-initiated clinical trials （IITs） constituted 48.29%. The proportions of ethical committees serving as primary reviewers and collaborative reviewers were 33.33% and 66.67%， respectively. The confirmation methods of mutual recognition outcomes were primarily expedited reviews （50.66%） and meeting reviews （49.34%）， and no cases of “direct confirmation” were found. The Chi-square test revealed statistically significant differences in review confirmation methods based on project type （χ²=14.851， P<0.001） and ethics committee role （χ²= 69.435， P<0.001）. The frequency distribution trend of the contingency table showed that IST projects and primary ethics committees preferred to employ meeting review （58.88% and 79.53% respectively， both higher than the average level of 49.34%）， while IIT projects and the collaborative ethics committees more frequently utilized expedited review （60.87% and 65.75% respectively， both higher than the average level of 50.66%）. ConclusionThe confirmation methods of mutual recognition for ethical review outcomes in multicenter clinical research are significantly associated with the role of the ethics committee and the type of project. It is recommended to improve management systems， enhance information construction and personnel training， as well as clarify mutual recognition responsibilities and strengthen supervision. This aims to ensure review quality while improving mutual recognition efficiency， thereby safeguarding the rights and interests of research participants.

Objective To investigate the anxiety and its related factors in medical staff during field training,so as to provide evidence for psychological education before field training.Methods A total of 81 medical staff who participated in field training were recruited in this cross-sectional study as research objects.The Hamilton Anxiety Scale(HAMA)and self-compiled questionnaires of related factors were used to measure the general states of the staff.Univariate analysis was used to screen relevant variables that affect anxiety,and then a logistic regression model was used for multivarate analysis to determine independent influencing factors.Results The detection rate of anxiety was 14.81%in the research objects.There were significant differences in the degree of anxiety among the medical staff with different variables such as gender,the number of exercises attended,childlessness,parental physical condition,tolerable training time,pastime activities,and personal title(P<0.05).Multivariate regression analysis indicated that gender and parental physical status were independent factors affecting anxiety(P<0.05).Conclusion During field training,a part of medical staff has anxiety,which may affect by multi-factors such as personal,family,and training environment.Therefore,psychological education and counseling before field training should be performed from multiple aspects.

Objective:To examine the therapeutic effects and molecular mechanisms of nuclear receptor NR4A1 in alleviating postoperative ileus (POI) in a rat model.Methods:Twenty-four Sprague-Dawley rats were randomly(random number) divided into four groups ( n=6/group): sham-operated control, POI model, POI model + NR4A1 stimultior (Cytosporone B, 13 mg/kg), and POI model + NR4A1 antagonist (DIM-C-pPhCO2Me, 2 mg/kg). After 24 hours, intestinal tissues and serum were collected for analysis. We assessed: (1) histopathological changes, (2) intestinal motility via propulsion rate, (3) NR4A1 expression by immunohistochemistry, (4) epithelial apoptosis via TUNEL assay, (5) inflammatory cytokines (IL-6, IL-4) by ELISA, (6) tight junction protein (occludin) by Western blot, and (7) p38MAPK/NF-κB pathway activation through combined western blot and immunofluorescence analyses. Results:Compared with sham controls, POI model rats showed (all P<0.05): significantly reduced NR4A1 expression, severe mucosal damage, increased inflammatory infiltration, elevated epithelial apoptosis, decreased occludin expression, impaired intestinal motility, upregulated pro-inflammatory cytokines (IL-6, IL-4), and activated p38MAPK/NF-κB signaling. NR4A1 activation with Cytosporone B significantly reversed these pathological changes (all P<0.05), while NR4A1 inhibition exacerbated them. Conclusions:NR4A1 activation attenuates POI by suppressing p38MAPK/NF-κB-mediated inflammation and preserving intestinal barrier function, suggesting its potential as a therapeutic target for postoperative ileus.

With the development of assisted reproductive technology, there will be more and more complex conflicts of interest issues and challenges. This paper used clinical medicine, legal and ethical analysis of WAS syndrome gene mutation assisted reproductive technology cases, emphasized that the law is the bottom line of morality, strengthen the consulting duty of the ethics committee of reproductive medicine, and pointed out that medical staff must fully perform the obligation of notification, respect their autonomy and provide patients with best medical assistance.

In order to further understand the cognitive attitude of different groups towards the rank of rights and interests in medical decision-making and its influencing factors, and provide theoretical reference for the practice of medical decision-making, this study conducted convenience sampling through the questionnaire star enterprise edition. The collected data were descriptive statistical analysis with SPSS 21.0 software and joint hypothesis testing. The results showed that there were differences in the cognition of religious beliefs on the same individual’s rights and interests rank among the sample population (P<0.05). There were differences in the cognition of professional title, working years and institution level on the attitude of rights and interests rank in the group of medical institutions (P<0.05). In the ranking of the importance of individual rights usually involved in medical activities, the rights to life, health and equality were the most important. Most people can rationally view the rights and interests of doctors, patients and stakeholders. In medical decision-making, we should adhere to the principle of right rank, give priority to safeguarding the right to life and give consideration to fairness and justice. In the face of conflicts of interest, we should do a good job in value evaluation, safeguard the reasonable interests of patients and give consideration to the demands of family members.

Objective To explore the current situation of evidence-based nursing practice in pain assess-ment by nurses in China to provide the decision-making data for maximizing to relieve the patient pain by car-rying out the pain assessment evidence-based nursing practice.Methods The non-probability sampling meth-od was used to conduct an online anonymous survey in 63 class 3A hospitals in the whole country.The ques-tionnaire included the general information questionnaire and evidence-based nursing practice scale for pain as-sessment.The evidence-based nursing practice scale for pain assessment included the pain screening,compre-hensive pain assessment,exchange with the patients and their households in the pain assessment,pain re-as-sessment,pain assessment tool selection and record.The 5 dimensions were compared by using item equaliza-tion.The data analysis was performed by the SPSS26.0.Results A total of 1 518 questionnaires were recov-ered,in which 1 482 questionnaires were valid with an effective recovery rate of 97.62％.The evidence-based nurse practice of pain assessment by nurse was(108.40±17.96)points,the pain screening was(12.87±2.23)points,the item average score was the highest[(4.29±0.74)points],the communication with the patients and their household was(23.69±4.93)points and the item average score was the lowest[(3.94±0.82)points].The regression analysis showed that whether receiving the pain training and whether distinguishing active pain and resting pain had a positive effect on the practical behavior(P＜0.05).Conclusion The evi-dence-based nursing practice in pain assessment by nurses in the partial class 3A hospitals in China is in the upper medium level.However,the communication between the patients and their families is insufficient.Man-agers should constantly enrich the training content and methods,and guide nurses to strengthen the communi-cation between nurses and the patients.

Specialist nurses play an increasingly important role in clinical,and at the same time,they(especially enterostomal therapists/wound stoma specialist nurses)are often troubled by ethical problems when facing patients independently.Based on the"structured analysis form of clinical nursing ethics"constructed in the early stage,this paper used a case study method,took a chronic wound patient with postpartum fat liquefaction combined with thread-knot reaction as an example,conducted an in-depth analysis and reflection on the ethical problems of enterostomal therapists choosing treatment plans in clinical work,as well as proposed clinical recommendations.Base on this,this paper suggests that specialist nurses should fully consider the wishes and background characteristics of patients when nursing and treating patients,and use the four-box model of ethical analysis to analyze and solve ethical conflicts.

On August 2-4,2023,the"Third Summit Forum on'Building a Community of Shared Future for Doctors and Patients'"was jointly organized by institutions such as the Chinese Medical Ethics,the Hospital Humanities Management and Talent Training Special Committee of the China Population and Culture Promotion Association,Center for Ethical Studies of Renmin University of China,the Newspaper for China's Physicians,the China Health Law Society,the China Anti-Cancer Association,and the China Association For Ethical Studies in Harbin.The conference arranged a sub-forum for the"Seminar on the Construction of Chinese Medical Humanities",with domestic medical humanities scholars attending the conference.After heated discussions at the seminar,the Scholars'Consensus on the Construction and Development of Chinese Medical Humanities was formed.It was proposed that in the new era,it is urgent to build the medical humanities discipline,as well as lead the academic integration and development of medical humanities under the core socialist values.At the same time,for the construction of the medical humanities discipline,it is necessary to optimize the organizational mechanism,prosper and develop the overall framework of the medical humanities discipline,accelerate the construction of a professional teaching team for the medical humanities discipline,promote the establishment of a new carrier medical humanities education and teaching in cultivating morality and nurturing talents,as well as focus on solving problems related to the cultivation of medical humanities graduate students.

Objective:To analyze the value of the modified 5-factor frailty index in assessing postoperative complications and mortality in elderly hip fracture patients.Methods:In this retrospective study, clinical data were collected of hip fracture patients aged 60 years and above surgically treated at Beijing Luhe Hospital affiliated to Capital Medical University between January 2015 and December 2019.Patients' group assignment was based on whether the modified frailty index score was ≤1 or ≥2, and a post-surgery follow-up was conducted for survival at 30 days, 1 year, 2 years, and 4 years, which was analyzed by the Kaplan-Meier method.Multivariate Cox regression analysis was used to identify factors affecting death in elderly patients.Results:A total of 1 208 patients were included, with 890 in the group with the index score ≤1 and 318 in the group with the index score ≥2.There was no difference in mortality at 30 days(1.6% or 14/890 vs.1.9% or 6/318, P=0.707), 1-year(11.3% or 99/874 vs.11.6% or 36/310, P=0.917), 2-years(19.7% or 168/852 vs.24.3% or 73/300, P=0.099)and 4-years(44.0% or 238/541 vs.51.5% or 106/206, P=0.071). The incidence of postoperative complications in the group with the score ≥2 was higher(14.8% or 47/318 vs.9.7% or 86/890, P=0.012), including the incidence of stroke(6.3% or 20/318 vs.1.8% or 16/890, P<0.001)and the incidence of postoperative pneumonia(6.0% or 19/318 vs.3.1% or 28/890, P=0.029), and the differences were statistically significant.Multivariate Cox regression analysis showed that age, being female, the Charlson comorbidity index score and low hemoglobin at admission were risk factors for 1-year, 2-year and 4-year mortality post-surgery(all P<0.05), while the modified frailty index score had no correlation with postoperative mortality. Conclusions:A modified frailty index ≥2 is predictive of increased risk of postoperative pneumonia and stroke in patients with hip fractures, but is not correlated with the risk of postoperative mortality.

Objective:To analyze the correlation between the grouping and weighting of two sets of disease combination systems, namely diagnosis-related groups(DRG) and diagnosis-intervention packet(DIP), and to establish a multidimensional analysis and evaluation mode by applying DRG, DIP, and clinical pathway to guide the standardized diagnosis and treatment and management of disease types.Methods:DRG grouping and DIP simulation full enrollment were applied to patients discharged from a tertiary Grade A general hospital in 2019. The correlation analysis between DRG, DIP, and clinical pathway inclusion(entry), correlation analysis between relative weight of DRG group and DIP standard score, and correlation analysis between clinical pathway entry and cost structure of the two disease groups were conducted by using chi-square test, Pearson correlation analysis, t-test, structural change value, degree of structural change, and incremental contribution rate. Results:Among the 130 395 patients, 41 460 cases entered the clinical pathway, 127 535 cases were enrolled in DRG, and 104 227 cases were enrolled in DIP. There was a correlation between the enrollment of DRG, DIP, and clinical pathway( P<0.05), and there was also a correlation between the relative weight of DRG groups and the enrollment of clinical pathway. The relative weight of the DRG disease group was positively correlated with the DIP standard score( r2=0.761 7, P<0.001). There was a significant difference in hospitalization costs between patients with and without clinical pathway access for some diseases( P<0.05), and different cost categories had different impacts on the total costs. Conclusions:The weight assignment and value orientation of DRG and DIP disease types are consistent, and the multi-dimensional fusion evaluation mode for DRG-DIP-clinical pathway is feasible. The correlation analysis of DRG, DIP, and clinical pathways can serve as the basis for disease classification and cost structure evaluation, which could help to carry out hospital′s refined management and optimize disease structure.
