ObjectiveTo develop an intervention program based on a shared mental model to enhance the communication and collaboration skills of nurses in multidisciplinary teams in stroke rehabilitation wards. MethodsUsing the shared mental model as the theoretical framework, the intervention program was preliminarily drafted through literature review to establish a theoretical foundation and qualitative research to identify clinical needs. The Delphi method was then used to revise and refine the program. ResultsBased on literature review and qualitative research, intervention elements were extracted across four dimensions: equipment, tasks, team interaction and team members, forming the initial draft of the intervention program. Two rounds of consultations were conducted with 18 experts, achieving a 100% valid response rate in both rounds. The expert authority coefficients were 0.87 and 0.90, respectively. In the second round of consultation, the variation coefficients for the importance scores of each item ranged from 0 to 0.20 (overall Kendall's W = 0.272, P < 0.001), and the variation coefficients for feasibility scores ranged from 0 to 0.21 (overall Kendall's W = 0.275, P < 0.001). The final intervention program included five first-level indicators, eight second-level indicators, and 29 third-level indicators, aligning with the four dimensions of the shared mental model. ConclusionThe intervention program was developed to enhance the communication and collaboration skills of nurses in multidisciplinary teams in stroke rehabilitation wards based on the shared mental model.

Objective To assess the clinical value of multimodal ultrasound score for assessment of endometrial receptivity among patients with polycystic ovary syndrome (PCOS), and to provide guidance for improving pregnancy outcomes among PCOS patients. Methods A total of 48 PCOS patients admitted to Jiangning Hospital Affiliated to Nanjing Medical University between January and December 2023 were enrolled as the case group, while 50 healthy women of childbearing age received ovulation monitoring at the same hospital during the same period served as the control group. Subjects received two-dimensional grayscale ultrasound during the implantation window (19 to 23 days of the menstrual cycle) for measurement of endometrial thickness, Gonen classification, and endometrial peristalsis. Two-dimensional color Doppler ultrasound was used for assessment of endometrial blood flow and three-dimensional ultrasound was used for assessment of endometrial volume and vascularization flow index (VFI). The endometrium multimodal ultrasound scores were estimated, and various parameters were compared between the two groups. The diagnostic performance of these parameters for PCOS was evaluated with receiver operating characteristic (ROC) curves. Results The age of subjects in the case group ranged from 20 to 38 years, with a mean age of (28.20 ± 2.82) years, and their body mass index (BMI) ranged from 21.23 to 29.11 kg/m², with a mean BMI of (26.25 ± 1.60) kg/m². The age of subjects in the control group ranged from 22 to 38 years, with a mean age of (28.10 ± 1.99) years, and their BMI ranged from 21.33 to 29.03 kg/m², with a mean BMI of (26.10 ± 1.78) kg/m². There were no significant differences between the case and control groups in terms of mean age, BMI, estradiol, and testosterone (t = 0.218, 0.422, 0.010, and 0.221; all P > 0.05). The endometrial thickness, endometrial volume, and VFI were significantly higher in the control group than in the case group (t = 4.838, 4.978, and 7.115; all P < 0.05). There were significant differences between the two groups in terms of endometrial classification, endometrial peristalsis pattern, and endometrial and sub-endometrial blood flow (Z = −4.136, −4.048, and −3.884; all P < 0.05). The scores of endometrial classification, endometrial peristalsis, endometrial and sub-endometrial blood flow, endometrial volume, VFI, and multimodal ultrasound were significantly lower in the case group than in the control group (t = 4.539, 4.449, 4.205, 3.209, 5.206, and 4.495; all P < 0.05). No significant difference was detected in the endometrial thickness score between the two groups (t = -0.149, P = 0.882). The areas under the ROC curves for endometrial thickness, endometrial volume, VFI, and multimodal ultrasound scores in diagnosis of PCOS were 0.753, 0.747, 0.809, and 0.858, respectively. Conclusion Multimodal ultrasound score provides a comprehensive assessment of the endometrium, and is effective in the assessment of endometrial receptivity, which may provide a reference for guiding pregnancy planning in PCOS patients.

Gastric cancer is a high-incidence malignancy that poses a serious threat to public health in China, ranking among the top three cancers in both incidence and mortality. The majority of patients are diagnosed at an advanced stage, resulting in limited treatment options and poor prognosis. To address key challenges in gastric cancer diagnosis and treatment, a research team led by Professor Jiafu Ji at Peking University Cancer Hospital has focused on the project "Development and Dissemination of Precision Medicine Approaches in Gastric Cancer Management". Through a series of high-quality multicenter clinical studies, the team established a set of new international standards in perioperative treatment, individua-lized drug selection, intelligent noninvasive diagnostics, and novel immunotherapy strategies. These advances have significantly improved treatment efficacy and reduced surgical trauma, achieving key technological breakthroughs in diagnosis, therapy, and mechanistic understanding, and systematically enhancing outcomes for gastric cancer patients. The project ' s findings had a broad international impact, including hosting China ' s first International Gastric Cancer Congress. Through nationwide dissemination, they have promoted the development of precision diagnosis and treatment of gastric cancer as a discipline, and led the formulation of the National Health Commission's guidelines for gastric cancer diagnosis and treatment. In recognition of its achievements, the project was awarded the First Prize of the 2024 Chinese Medical Science and Technology Award.

Objective:To explore the current situation of the intrinsic capacity of elderly people in the community and analyze its influencing factors.Methods:From September 2022 to March 2023, convenience sampling was used to select 360 elderly community residents from Xicheng District, Beijing, and Xingtai City, Hebei Province, as the research subjects. The subjects were surveyed using the Intrinsic Capacity Assessment Questionnaire, Intrinsic Capacity Influencing Factors Questionnaire, Barthel Index, and Lawton Instrumental Activities of Daily Living Scale.Results:A total of 360 questionnaires were distributed, and 360 valid questionnaires were collected, with an effective response rate of 100.0% (360/360). The overall impairment rate of intrinsic capacity among 360 elderly people in the community was 90.3% (325/360), and the impairment rates in various fields from high to low were sensation, psychology, vitality, cognition, and exercise. Multiple linear regression analysis showed that age, gender, residential pattern, education level, work status, grip strength, number of geriatric syndrome, self-rated health status, adverse life events, number of social activities, transportation conditions, and social security were the influencing factors of the intrinsic capacity of elderly people in the community, and the difference was statistically significant ( P<0.05) . Conclusions:The impairment rate of intrinsic capacity among elderly people in the community is relatively high. Grassroots medical and nursing staff should assess the intrinsic capacity of elderly people in the community in health promotion work, identify elderly people with decreased intrinsic capacity early and carry out effective interventions to prevent elderly people from becoming disabled and dependent on care.

Objective:To systematically evaluate the real feelings and coping experiences of nursing students in geriatric nursing, so as to provide reference for nursing students to carry out geriatric nursing practice.Methods:Qualitative research on the geriatric nursing experience of nursing students was electronically searched in Chinese and English databases such as PubMed, Cochrane Library, Web of Science, Embase, CINAHL, China National Knowledge Infrastructure, Wanfang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to June 2023. The quality of the included literature was evaluated according to the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center. The aggregation integration method was used to integrate literature results.Results:A total of 16 articles were included, and 41 results were extracted. The similar results were classified into eight categories and integrated into two integrated results, which were the challenges and obstacles faced by nursing students in the geriatric nursing process, as well as the experience of various complex emotions, and nursing students had a positive experience in the process of geriatric nursing, gaining personal growth and sublimation of values.Conclusions:Nursing educators should attach importance to the geriatric nursing experience of nursing students, pay attention to and guide their negative emotions and experiences, encourage nursing students to establish well interactive relationships with the elderly, and improve the comprehensive quality of geriatric nursing among nursing students through the design and implementation of emerging clinical teaching models.

Objective:To provide evidence-based recommendations for the prevention and management of lower limb ischemia in veno-arterial extracorporeal membrane oxygenation (VA-ECMO) patients during treatment according to search, evaluate, and summarize the best evidence on the prevention and management of lower limb ischemia in patients with VA-ECMO.Methods:Based on the PIPOST framework (population, intervention, professional, outcome, setting, and type of evidence), an evidence-based question was formulated. A systematic search was conducted according to the "6S" evidence pyramid model in both domestic and international databases, as well as professional association websites, for all evidence related to the prevention and management of lower limb ischemia in VA-ECMO patients (aged ≥18 years). The types of evidence included clinical decisions, guidelines, expert consensus, systematic reviews, evidence summaries, and original studies. The search was conducted from the construction of the databases to February 2024. Two researchers independently conducted a literature quality evaluation, extracted and summarized evidence from the studies that met the quality criteria.Results:A total of 13 articles were included, consisting of 3 clinical decisions, 3 guidelines, 3 expert consensus, 3 systematic reviews, and 1 randomized controlled trial. A total of 18 pieces of evidence in 7 dimensions were summarized, including risk factors of VA-ECMO lower limb ischemia, evaluation before catheterization, evaluation and monitoring during treatment, prevention of lower limb ischemia, treatment of lower limb ischemia, management of distal perfusion catheter (DPC), and monitoring after VA-ECMO weaning.Conclusion:This evidence summary provides evidence-based recommendations for the prevention and management of lower limb ischemia in VA-ECMO patients, aiming to assist clinical healthcare professionals in developing tailored strategies for the prevention and management of lower limb ischemia based on during VA-ECMO support.

Objective:To investigate the effects of tetrabromobisphenol A (TBBPA) on ionizing radiation (IR)-induced liver toxicity based on a zebrafish model and provide a scientific basis for assessing microplastic-radiation exposure hazards to the survival and health of aquatic organisms and humans.Methods:Healthy adult zebrafish aged 4-6 months were grouped (20 fish each group, sex in half) by random number table method in three different ways. The TBBPA exposure concentration screening experiment was divided into 4 groups: control group and TBBPA (3, 30 and 300 μg/L) treatment groups. The experiment of effects of double exposure on liver function was divided into 5 groups: control group, IR (10, 20 or 30 Gy) groups and IR+ TBBPA (60, 300 and 1 500 μg/L) treatment groups. The experiment of effects of TBBPA on hepatic radiation toxicity was divided into 3 groups: control group, IR (20 Gy) group, and IR+ TBBPA (300 μg/L) group. The changes in liver function indexes, oxidative stress markers, pro-inflammatory cytokines, and liver cell apoptosis were monitored, differential metabolic pathways and metabolites were identified upon untargeted metabolomics assays, and inter-group data were compared by One-way ANOVA test.Results:The activities of ALT and AST in zebrafish liver increased in a dose-dependent manner after exposure to TBBPA, and the differences between 300 μg/L TBBPA group and control group were statistically significant ( t=-2.22, -3.20, P<0.05). IR at a dose of 20 Gy or above induced a significant decline of liver function, and at this radiation dose, combined exposure to 300 μg/L or above TBBPA intensified the liver toxicity (compared with the control group, t=-8.18 to -4.63, P<0.05, compared with IR group, t=-5.22 to -0.30, P < 0.05). Compared with the control group, the activities of ALT and AST, levels of ROS, MDA and SOD, mRNA and protein expression levels of TNF-α, IL-1β, Cox-2, Caspase-8 and Caspase-9, and cell apoptosis in zebrafish livers of IR and IR+ TBBPA groups increased gradually (compared with the control group, t=-12.29 to -2.88, P<0.05, compared with IR group, t=-4.40 to -2.31, P<0.05). The differences in the content of D-gluconic acid, p-cresol and other metabolites in liver tissues were more and more significant among the three groups, involving multiple KEGG pathways such as biosynthesis, degradation and metabolism. Conclusions:Exposure to 300 μg/L TBBPA can aggravate IR-induced liver toxicity of zebrafish, which involves the mechanism that further elevates the levels of oxidative stress, inflammation, and apoptosis, as well as radiation-induced liver metabolic disorders.

Objective By comparing with arthroscopic rotator cuff repair alone,to explore the efficacy and difference of leukocyte poor platelet-rich plasma(LP-PRP)and leukocyte rich platelet-rich plasma(LR-PRP)in arthroscopic rotator cuff repair.Methods Sixty patients with total rotator cuff tear accompanied by arthroscopic rotator cuff repair admitted to the Affiliated Hospital of North China University of Science and Technology from October 2021 to September 2022 were included and randomly divided into control group(n=20),LP-PRP group(n=20)and LR-PRP group(n=20).The control group only received arthroscopic rotator cuff repair.The LP-PRP group was injected with leukocyte poor platelet-rich plasma(LP-PRP)into the sutured torn tendon after the same operation,and the LR-PRP group was injected with leukocyte rich platelet-rich plasma(LR-PRP)into the sutured torn tendon after the same operation.The postoperative rehabilitation training plan of the three groups was the same,and the postoperative follow-up and evaluation were conducted for 1 year.It included pain score(VAS score),shoulder joint function score(CMS,UCLA,ASES score),retear rate and related complications.Results All patients were followed up.(1)VAS score:Compared with the LR-PRP group and the control group,the results were statistically significant only at 1,3 and 6 weeks after surgery(P<0.05);There was no statistical significance between the LR-PRP group and the control group at 1 week,3 weeks,6 weeks,3 months,6 months and 12 months after surgery(P>0.05).(2)CMS,UCLA and ASES scores:There were no significant differences between the LP-PRP group and the LR-PRP group at 3 months,6 months and 12 months after surgery(P>0.05);Compared with LP-PRP group and LR-PRP group,there were significant differences in each follow-up time point of control group(P<0.05).(3)Retear rate:In the LP-PRP group,there was 1 retear in the LR-PRP group(tear rate 5%),and 3 in the control group(tear rate 15%).There was no statistically significant difference between the three groups(P>0.05).(4)There were no postoperative complications in 60 patients.Conclusions Compared with arthroscopic rotator cuff repair alone,although the application of LP-PRP and LR-PRP could not reduce the rate of retear,it could significantly improve the shoulder joint function of patients,and LP-PRP could significantly reduce the pain of patients with rotator cuff injury in the early postoperative period(within 6 weeks),with no postoperative complications,and the short-term clinical results of patients were satisfactory.
