Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

Objective To explore the effect of sorafenib on HeLa cell proliferation by inducing cell apoptosis and autophagy and its impact on drug resistance.Methods The drug-resistant cell strains were constructed through in-termittent induction method,with concentrations of 0,2.5,5.0,7.5,10.0,15.0,20.0 μmol/L.HeLa cells were incubated with increasing concentrations of sorafenib with each concentration for 1 week.The drug-resistant cell strains with stable passages were collected.MTT assay was used to detect the effect of sorafenib on cell prolifer-ation.Cell cycle distribution was analyzed by flow cytometry.The change in the expression of drug-resistant and ap-optotic genes in the parents and drug-resistant cell strains under different drug concentrations was examined by semi-quantitative PCR.The changes of apoptotic related marker proteins LC3-Ⅰ and LC3-Ⅱ were detected by Westernblot.Results Stable drug-resistant strains were successfully obtained;Drug-treated cells were more blocked in the G1 phase.In drug-resistant cells,the expression of apoptosis suppressor gene Bcl-2 was significantly decreased and the apoptotic gene Bax as well as the drug-resistant genes were all significantly increased(P＜0.05).The LC3-Ⅱ/LC3-Ⅰ ratio of drug-resistant cells was significantly higher than that of parent cells(P＜0.05).Conclusions Sorafenib may block the cell cycle,suppress malignant cell proliferation and promote autophage.On one hand,autophagy participates in the development of cell drug resistance and promotes cell survival.On the other hand,drug-induced autophagy may activate some of apoptotic signaling pathway in drug-resistant cells and promote the reversal of cell drug resistance.

Objective:To explore the status and influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Methods:This is a cross-sectional study. From January to February 2022, a total of 3 047 cardiovascular nurses in members of China Cardiovascular Health Alliance were selected as research objects by convenience sampling method. General data questionnaire and Cardiovascular Nurses Participated in the Cardiac Rehabilitation Questionnaire (CNPCRQ) were used to investigate cardiovascular nurses.

A total of 3 047 questionnaires were distributed in this study, and 2 704 valid questionnaires were effectively received, with an effective recovery rate of 88.74%.Results:The total score of CNPCRQ of cardiovascular nurses was (93.23±31.58), which was at a moderate level. Multiple linear regression analysis results showed that age, education, professional title, hospital location, hospital level, position type and hospital type were the influencing factors of participation in cardiac rehabilitation of cardiovascular nurses.Conclusions:The status of participation in cardiac rehabilitation of cardiovascular nurses in China needs to be improved. Role and job content of cardiovascular nurses should be further clarified, and cardiac rehabilitation knowledge and skills training should be strengthened in the future, so as to promote the profession development of cardiac rehabilitation and improve patients' health outcomes.

Objective:To explore the effect of online and offline blended scenario simulation teaching in the practice of nursing undergraduates.Methods:From August 2020 to May 2021, convenience sampling was used to select 76 nursing undergraduates in the class of 2017 who practiced in the Cardiology Department of the Second Affiliated Hospital of Harbin Medical University as the research object. The undergraduates were randomly divided into the experimental group and the control group, 38 in each group. The control group received the traditional graduation practice training, and the experimental group received online and offline blended scenario simulation teaching on this basis. After the practice, the clinical thinking ability of the two groups of students was evaluated by the Clinical Thinking Ability Evaluation Scale, the clinical practice ability of the two groups of students was evaluated by the Objective Structured Clinical Examination (OSCE) , and a teaching satisfaction survey was conducted.Results:The total score of clinical thinking ability, critical thinking ability, systematic thinking ability, evidence-based thinking ability, OSCE total score of the students in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05) . The students in the experimental group thought that the teaching method was helpful for in-depth understanding and application of theoretical knowledge, improving nursing assessment skills, clinical coping skills and communication skills, and at the same time helping to cultivate critical thinking and teamwork awareness, and arouse learning enthusiasm, and the differences were statistically significant (all P<0.05) . Conclusions:The online and offline blended scenario simulation teaching can effectively improve the clinical thinking ability, clinical practice ability and teaching satisfaction of nursing undergraduates, and it has good effect in the graduation practice of undergraduate nursing students.

Objective:To explore the effects of mindfulness-based stress reduction training (MBSRT) on anxiety and depression levels and sleep quality of clinical nurses.Methods:Totally 90 clinical nurses from the Second Hospital of Harbin Medical University were selected by convenient sampling from April 2018 to June 2019, and were divided into experimental and control groups according to the order of enrollment, with 45 cases in each group. Nurses in the control group received routine sleep and emotional guidance, while nurses in the experimental group underwent MBSR training on this basis. Self-Anxiety Scale (SAS) , Self-Depression Scale (SDS) , and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate the intervention effect in both groups 1 day before the intervention and the day when the intervention was completed. Finally, 44 nurses in the experiment group and 45 in the control group completed the study.Results:Before the MBSRT intervention, there was no statistically significant difference in the SAS, SDS, and PSQI scores between the two groups of nurses ( P>0.05) . After the intervention, the SAS and SDS scores of nurses in the experimental group were lower than those of the control group, and the differences were statistically significant ( t=-3.117, -3.498; P<0.05) ; the total PSQI score and scores in such dimensions as subjective sleep quality, sleep latency, sleep continuity, sleep efficiency, sleep disorder, hypnotic drug use, and daytime dysfunction in the experimental group were lower than those of the control group, and all differences were statistically significant ( P<0.05) . Conclusions:MBSRT can effectively reduce the level of anxiety and depression and improve the sleep quality of clinical nurses.

Objective To observe the differences of biological property of glioma stem cells (GSCs) and glioma non-stem cells (nGSCs), and their related protein expressions. Methods The proliferations of GSCs1, GSCs2 and nGSCs1 and nGSCs2 were detected by CCK8 after two, 4, 6, 8, 10 and 12 d of culture in vitro. The sensitivities of the cells to temozolomide (TMZ) were detected by CCK8 after 2 d of culture. The adhesion abilities of cells were tested by adhesion assay. Transwell assay was used to detect the migration and invasion abilities of cells. The activity of matrix metalloproteinase-2 (MMP-2) was detected by gelatin zymography. Western blotting and immunofluorescence staining were used to detect the protein expressions of Notchl and epidermal growth factor receptor (EGFR). Results The survival rate of nGSCs1 was significantly higher than that of GSCs1 and the survival rate of nGSCs2 was significantly higher than that of GSCs2 after 4, 6, 8, 10 and 12 d of culture (P<0.05). The inhibitory concentration (IC)50 of TMZ for GSCs1, nGSCs1, GSCs2 and nGSCs2 was (1536.0±17.67) μmol/L, (514.5±13.44) μmol/L, (2543.0±39.87) μmol/L, (889.6±17.43) μmol/L, respectively (P<0.05). Number of GSCs1 adhering to extracellular matrix proteins Fibronectin and Collagen I was significantly larger than that of nGSCs1, and that of GSCs2 was significantly larger than that of nGSCs2 (P<0.05). The number of migrated GSCs112 and 24 h of cultivation was statistically larger than that of nGSCs1, and that of GSCs2 was statistically larger than that of nGSCs2 (P<0.05). The number of invaded GSCs124 and 36 h of cultivation was larger than that of nGSCs1, and that of invaded GSCs2 was larger than that of nGSCs2, with statistical differences (P<0.05). The activity of MMP2 secreted by GSCs1 was significantly higher than that by nGSCs1, and that of MMP2 secreted by GSCs2 was significantly higher than that by nGSCs2 (P<0.05). Western blotting showed that the relative protein expression level of EGFR/Notch1 in GSCs1 was significantly lower than that in nGSCs1, and that in GSCs2 was significantly lower than that in nGSCs2 (P<0.05). The results of immunofluorescence staining were consistent with those of Western blotting; EGFR protein strongly expressed in nGSCs and weakly expressed in GSCs; Notch1 protein strongly expressed in GSCs and weakly expressed in nGSCs. Conclusion As compared with the high-EGFR-expressing and proliferative primary glioma cells, the high-Notch1-expressing glioma stem cells have higher activity level of MMP-2,stronger abilities of adhesion, migration and invasion, which may be contributed to glioma treatment resistance and its occurrence.

Objective To retrospectively analyze the implementation of the antimicrobial agents prescription monthly review at the emergency and outpatient departments for the past five years, for evaluation of its action in promoting rational application of antimicrobial drugs. Methods At the baseline investigation stage, 1780 prescriptions on antibiotics in emergency and outpatient department from June 2012 to November 2012 were randomly selected for centralized evaluation. The period of correction and observation falls into two stages. The first stage ranged from December 2012 to February 2015, when the prescription of antibiotics was sampled manually for monthly review. The second stage ranged from March 2015 to June 2017, when a prescription review software for prescription comment was introduced for the sample purpose. The data so acquired were subject to chi-square test and linear regression analysis using Excel 2010 and SPSS 16. 0. Results The rational rate of prescription for antibiotics at the emergency department increased from 80. 56％ of the baseline stage to 99. 47％ of the second stage (166506/167400), scoring a difference of statistical significance (P<0. 001). With intervention of the prescription review software, the percentage of irrational use of antimicrobial agents dropped by 5. 18％ compared to the baseline stage. Conclusions Monthly prescription review on antimicrobial agents at the outpatient and emergency departments could promote the rational use of antimicrobial agents and play an important role in clinical drug safety. Information system and performance assessment contributed to the effect of prescription review.

Objectives: To study the changes of blood levels of soluble semaphorin 4D (sSema4D) and matrix metalloproteinases-14 (MMP-14);to explore the correlation between sSema4D and ventricular remodeling in patients of dilated cardiomyopathy with chronic heart failure.
Methods: Our research included in 2 groups:Dilated cardiomyopathy group, n=86 patients and Control group, n=32 healthy subjects. Blood levels of sSema4D, MMP14, Pro-BNP and hs-CRP were examined by ELISA. Left atrial diameter (LAD), right ventricular diameter (RVD), ejection fraction (EF), left ventricular end diastolic diameter (LVEDD), left ventricular fractional shortening (LVFS) were measured by echocardiography. Correlation analysis between blood levels of sSema4D, MMP-14 and the parameters for left ventricular remodeling was conducted.
Results: Blood levels of sSema4D and MMP14 were different between 2 groups, P<0.005. In Dilated cardiomyopathy group, sSema4D level was positively related to MMP-14 and LVEDD (r=0.462, P=0.001 and r=0.643, P<0.001) respectively.
Conclusion: Serum level of sSema4D might be related to ventricular remodeling in patients with dilated cardiomyopathy which could be used as risk factor for predicting the prognosis of heart failure in relevant patients.
