Objective Under the operation background of Diagnosis-Intervention Packet(DIP),whether there is interaction between reducing medical cost and average length of stay combined with pre-hospitalization mode,and whether there is difference between different departments and diseases in interaction.Methods Based on real-world data from 71 453 patients admitted to Guizhou Provincial People's Hospital from July to December 2021,a two-way analysis of variance was employed.When the interaction effect was statistically significant,parameter estimation was used to determine the magnitude and direction of the interaction effect,followed by subgroup analyses by department and disease.Results Without adjustment,both total medical costs and average length of stay exhibited a negative interaction effect(P＜0.05).Subgroup analyses revealed that in terms of total medical costs,the effect size for the surgical system was 0.18％,lower than that for the internal medicine system(0.70％);for core diseases,it was 6.62％,lower than that for comprehensive diseases(7.71％).Regarding average length of stay,the effect size for the surgical system was 0.55％,better than that for the internal medicine system(0.22％);for core diseases,it was 8.70％,higher than that for comprehensive diseases(2.90％).Conclusion The combination of DIP payment reform and pre-admission management model demonstrates a synergistic effect,effectively reducing patients' medical costs and length of stay.This effect is influenced by disease complexity and the standardization of diagnostic and treatment processes.

ObjectiveTo investigate the current status and related factors of maternal influenza vaccination willingness among pregnant and postpartum women in Shanghai and Liaoning Province, China, and to explore the facilitators and barriers affecting vaccination uptake, so as to provide references for future practices in promoting maternal influenza immunization in China. MethodsA convergent mixed-methods research was conducted. From January to March 2024, a questionnaire survey was conducted among women attending prenatal and postnatal care at 7 medical institutions in Shanghai and Dalian, Liaoning Province, which aimed to assess pregnant women’s knowledge about influenza vaccine and their willingness to vaccination during pregnancy, as well as to identify the related factors. In addition, purposive sampling method was used to conduct in-depth interviews with pregnant women and perinatal healthcare service providers to explore their perspectives on influenza vaccination during pregnancy, including the reasons for their willingness or unwillingness to receive ( or recommend) the vaccine, and the relevant facilitators and barriers to vaccination. ResultsA total of 366 pregnant and postpartum women participated in the questionnaire survey, and 9.56% (35/366) of them were willing to receive the influenza vaccine during pregnancy. The results of multivariate logistic stepwise regression analyses showed that primipara (aOR=0.158, 95%CI: 0.037‒0.671, P=0.012), family members’ support for influenza vaccination during pregnancy (aOR=0.015, 95%CI: 0.003‒0.082, P<0.001) were associated with higher willingness to receive influenza vaccine during pregnancy. Absence of influenza infection during pregnancy (aOR=5.383, 95%CI: 1.801‒16.092, P<0.001), and lack of knowledge regarding influenza vaccination during pregnancy (aOR=11.294, 95%CI: 3.593‒35.496, P<0.01) were associated with lower willingness to receive influenza vaccine during pregnancy. Qualitative findings indicated that the facilitators to vaccination willingness among pregnant and postpartum women included the recommendation of healthcare service providers, adequate knowledge of influenza vaccine information and family members’ support for vaccination. Conversely, the barriers to vaccination willingness included low recommendation from the healthcare service providers, lack of knowledge about the safety of influenza vaccine during pregnancy and inadequate attention to influenza and influenza vaccine. ConclusionThe willingness to receive influenza vaccination among pregnant and postpartum women in Shanghai and Liaoning Province is relatively low. It is recommended that China should promptly improve the evidence-based system for the safety and efficacy of influenza vaccines for pregnant and postpartum women, along with an establishment of the mechanism for addressing adverse reactions. Furthermore, it is essential to enhance educational outreach to pregnant and postpartum women, their families, and healthcare service providers, thereby increasing the accessibility of information regarding influenza vaccination, which are expected to enhance the willingness of pregnant and postpartum women to receive the vaccine.

Neddylation is a crucial posttranslational modification that involves the attachment of neural precursor cell-expressed developmentally downregulated protein 8(NEDD8)to a lysine residue in the substrate via the sequential actions of the E1 NEDD8-activating enzyme(NAE)(E1),E2 NEDD8-conjugating enzyme(E2),and E3 NEDD8-ligase(E3).The most extensively studied substrates of neddylation are members of the cullin family,which act as scaffold components for cullin ring E3 ubiquitin ligases(CRLs).Since cullin neddylation activates CRLs,which are frequently overactive in tumors,inhibiting neddylation has emerged as a promising strategy for developing novel antitumor therapies.This review explores the antitumor effects of inhibiting neddylation that leads to the inactivation of CRLs and provides a summary of known inhibitors that target protein-protein interactions(PPIs)within the neddylation enzymatic cascade.

Objective:To explore the effects and potential mechanisms of cell growth regulator 1 ( CGREF1) with an EF hand domain in colorectal cancer proliferation and migration. Methods:Fifty paraffin specimens of colorectal cancer tissues and corresponding paracancerous tissues were selected from January 2023 to January 2024 from the Northern Jiangsu People's Hospital Affiliated to Yangzhou University for analysis, and TCGA, GDSC, KMPLOT and STRING databases were used to explore the expression, prognosis, immune microenvironment, drug sensitivity and related signaling pathway functions of CGREF1 in colorectal cancer. Tissue and cellular expression levels of CGREF1 were analyzed by immunohistochemistry and qRT-PCR. Lentiviral-mediated CGREF1 overexpression in SW-620 cells (OE- CGREF1 vs NC groups) was functionally characterized through CCK-8 proliferation assays, colony formation tests, and scratch wound healing migration assays, with mechanistic investigation via Western blot analysis of apoptosis markers, invasion-related proteins, and RAS/RAF/ERK pathway components. In vivo tumorigenicity was assessed by subcutaneous injection of control or CGREF1-overexpressing SW620 cells in nude mice ( n=3 per group) with tumor growth monitoring. Software of GraphPad Prism 9 was used for statistical analysis of experimental data. Results:CGREF1CGREF1RASERK Studies based on databases, clinical samples and colorectal cancer cell line analyses demonstrated that CGREF1 is downregulated in colorectal cancer, where low CGREF1 expression showed positive correlation with tumor diameter and invasion depth. CGREF1 is closely related to tumor immune infiltration microenvironment and sensitivity to multiple anti-tumor drugs. Overexpression of CGREF1 promoted cell apoptosis while inhibiting cell proliferation, invasion and migration. Overexpression of CGREF1 downregulated the expression levels of RAS, ERK and P-P38/MAPK pathway proteins. CGREF1 inhibited tumor growth in vivo. Conclusion:CGREF1 can inhibit the proliferation, colony formation, and migration of CRC cells through the RAS/ERK/MAPK pathway.
