Objective:To evaluate the application effect and long-term benefits of in situ simulation combined with the forgetting curve training mode in trauma nurse training, and to provide a basis for further promoting the development of trauma nurse training.Methods:From June to September 2022, a total of 78 nurses in the Trauma Center of a grade A tertiary hospital in Changsha, China were selected by the purposive sampling method as the research objects. The nurses were divided into an experimental group and a control group according to the random number table method. The control group received theoretical teaching and skill operation training by traditional teaching methods. The experimental group was trained by the teaching method of in-situ simulation combined with the forgetting curve. The scores of theoretical and operational skills of the two groups were compared by the repeated measures analysis of variance (ANOVA) before training (T1), 1 day after training (T2), 1 month after training (T3), and 6 months after training (T4). The scores of core competence of trauma nurses before and after training were compared between the two groups by the t test. Results:There was no significant difference in theoretical, operational, and core competence scores between the two groups before training ( P>0.05). The results of repeated measures ANOVA showed significant differences in the time effect, inter-group effect, and interaction effect of theoretical and operational scores between the two groups ( P<0.001). The results of one-way repeated measures ANOVA showed that the theoretical and operational scores of the two groups increased first and then decreased with time. The results of multivariate ANOVA showed no significant difference in theoretical and operational scores between the two groups at observation time point T1 ( P>0.05), but significant differences at observation time points T2, T3, and T4, at which the scores in the experimental group were higher than those in the control group ( P<0.001). The results of independent samples t test showed that the core competence score of trauma nurses in the experimental group was significantly higher than that in the control group after training ( P<0.05). Conclusions:The training mode of in situ simulation combined with the forgetting curve is more effective than traditional training mode in improving the professional skill level of trauma nurses and brings long-term training effect and benefits.

The fundamental pathogenic mechanisms of inflammatory bowel disease(IBD),a chronic inflammatory illness affecting the gastrointestinal tract,are still not fully understood.Dipeptidyl peptidase Ⅳ(DPP-4)is a glycoprotein found on the cell surface that has signaling and enzymatic properties.In addition,there is growing evidence from animal models and clinical trials that DPP-4 inhibitors have potential impacts beyond only lowering blood sugar levels,such as immunomodulatory and anti-inflammatory capabilities.This article reviews the biological properties of DPP-4 and its research progress in the diagnosis and treatment of IBD.It also discusses the mechanism of DPP-4 in IBD,aiming to provide a more in-depth understanding of the role of DPP-4 in IBD.

Preterm birth is the most common maternal complication in twin pregnancies. In recent years, cervical cerclage has been of long-standing interest in the prevention of preterm birth in twin pregnancies. However, its clinical application in the treatment of cervical insufficiency of twin pregnancies remains a controversial subject. In addition, infection or inflammation conditions are considered to be closely related to the perinatal outcomes of twin pregnancies after cervical cerclage. This paper reviews the research progress on cervical cerclage in twin pregnancies, recommending cervical cerclage for twin pregnancies with cervical length≤15 mm or cervical dilatation, while it is not suggested for those with cervical length of 15-25 mm or history-indicated cervical cerclage. The clinical significance of preoperative evaluation of intraamniotic infection or inflammation of twin pregnancies needs to be further explored, but it is necessary to avoid the effect of antibiotic use on the evaluation of surgical effects.

Objective:To investigate the effect of Yinertong antibacterial fluid combined with Yintshu antibacterial gel on puncture wound infection in pleural catheter drainage.Methods:A total of 80 patients who underwent pleural catheter drainage in Gulou Hospital Affiliated to Medical College of Nanjing University from January 2018 to December 2019 were enrolled. They were divided into the control group and the experimental group by random digits table method, with 40 cases each. The control group was given alcohol disinfection and traditional iodophor. The experimental group was given Yinerong antibacterial fluid combined with Yintshu antibacterial gel. The infection of puncture wound, degree of edema, incidence of catheter displacement, colonization rate of catheter pathogens, pain, and nursing satisfaction were observed and compared between the two groups.Results:The wound infection rate was 15% (6/40) in the control group, and 0(0/40) in the experimental group, the difference was statistically significant ( χ2=4.50, P<0.05). There was no significant difference in colonization rate of catheter pathogens between the two groups ( P>0.05). There were 28, 6, 4 and 2 cases of no edema, mild, moderate and severe edema in the control group and 38, 1, 1 and 0 cases in the experimental group, the difference was statistically significant ( Z=8.19, P<0.05). There was no significant difference in the scores of Visual Analogue Scale (VAS) of immediate pain of puncture between the two groups ( P>0.05). The score of VAS after 24 hours of puncture and at the time of extubation was (3.10 ± 1.34), (1.50 ± 1.36) points in the experimental group, and (3.83 ± 1.28), (2.38 ± 1.28) points in the control group, the differences were statistically significant ( t=2.48, 2.97, both P<0.05). The satisfaction rate after discharge was 97.5% (39/40) in the experimental group, and 80.0% (32/40) in the control group, the difference was statistically significant ( χ2=8.31, P<0.05). Conclusions:The combined application of Yinertong antibacterial fluid and Yintshu antibacterial gel can significantly reduce the wound infection rate of pleural catheter drainage, reduce wound edema and pain, and improve patients′ satisfaction with nursing work, which is worthy of popularization and application.

Purpose: The incidence rate of breast cancer (BC) has increased annually. Downstream neighbor of son (DONSON) critically affects cell cycle progression and maintains stable genomic properties; however, its relevant effects on BC growth and progression require indepth investigation. Methods: DONSON upregulation was validated in public databases. DONSON expression in matched BC and adjacent tissues and cell lines (MDA-MB-231, BT-549, and HS-578T) was determined using quantitative reverse transcription polymerase chain reaction. In vitro apoptosis, invasion, migration, and proliferation tests were performed to ascertain the functions of DONSON in BC cell lines. Then, using western blot analysis, the levels of DONSON downstream proteins were determined. Results: Compared to the control, DONSON was expressed at higher levels in BC tissues and cell lines. DONSON knockdown facilitated apoptosis and limited proliferation, migration, invasion, and S/G2 transition of BC cells In vitro. Furthermore, DONSON overexpression promoted BC cell proliferation and inhibited apoptosis In vitro. Moreover, DONSON knockdown reduced cyclin A1 and cyclin-dependent kinase 2 levels. Moreover, DONSON knockdown limited the progression of epithelial-mesenchymal transition. Conclusion DONSON critically affects BC growth and serves as a possible target and marker for the efficacy of subsequent therapies.

Objective:To explore the current situation of motoric cognitive risk syndrome (MCR) in the community elderly in Taiyuan and analyze its influencing factors.Methods:From January to April 2021, convenience sampling was used to select 500 elderly people from 5 communities in Taiyuan as the research object. The elderly were investigated with the General Information Questionnaire, Mini-Mental State Examination (MMSE) , simplified Geriatric Depression Scale-15 (GDS-15) , Short-Form Mini Nutritional Assessment (MNA-SF) and Lubben Social Network Scale-6 (Lubben-6) , and 4-meter walk test.Results:A total of 500 questionnaires were distributed, and 492 valid questionnaires were recovered, with a valid recovery rate of 98.40%. The prevalence of MCR among 492 community elderly people in Taiyuan was 11.38% (56/492) . Univariate analysis showed that there were statistically significant differences in the incidence of MCR among the community elderly in Taiyuan with different age, education level, obesity, living alone, number of diseases, diabetes, coronary heart disease, stroke, number of medications, chronic pain, nutritional status, depression and social isolation ( P<0.05) . Logistic regression analysis showed that educational level, obesity, diabetes, chronic pain, nutritional status, depression, and social isolation were the influencing factors of MCR in the elderly in Taiyuan ( P<0.05) . Conclusions:The incidence of MCR among the elderly in Taiyuan is high. Individualized interventions should be formulated according to the influencing factors to prevent or delay the occurrence of MCR in the community elderly.

Objective:To explore the impact of mentors' behaviors on the professional identity of medical students during the internship.Methods:Based on the data of the China Medical Students Survey in 2020, a research was conducted on 25 557 medical graduates from 104 universities in China. The Wilcoxon rank-sum test and multiple linear regression were used to analyze the impact of mentors' behaviors on the professional identity of medical students during the internship.Results:More than 70% of medical students believed that the clinical mentors they met during their internship had positive medical and teaching behaviors. If students believed that clinical mentors were enthusiastic, responsible for their work, highlighted role modeling and paid attention to their behaviors in teaching, the scores of professional identity would be 3.027, 0.445, 0.840 and 1.234 points greater than if they did not respectively (all P<0.001). Conclusion:The students have generally good evaluation on mentors' behavior during the internship. The positive medical and teaching behaviors of mentors have a positive impact on the professional identity of medical students and the impact of enthusiasm is the greatest. Medical institutions should provide complete institutional support and standardize the behavior of clinical teachers in order to enhance the professional identity of medical students.
