Objective:To systematically evaluate and synthesize qualitative studies on the journey experiences and needs of patients with cancer-associated venous thromboembolism (CAT) , providing reference for developing full-course intervention strategies oriented to CAT prevention and management needs.Methods:Literature was retrieved from PubMed, Web of Science, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure, Wanfang Data, and VIP regarding qualitative studies on CAT patients' prevention and management journey experiences and needs, from database inception to June 30, 2024. The quality of included literature was assessed using the 2024 version of the Joanna Briggs Institute (JBI) Qualitative Research Quality Appraisal Criteria. Findings were synthesized using a Meta-synthesis approach.Results:A total of 13 studies were included, from which 104 themes were extracted and categorized into 12 new categories, ultimately integrated into three synthesized findings: tasks change as the journey progresses; emotions gradually shift from negative to positive; pain points are key areas to improve the journey experience.Conclusions:CAT patients experience varying journey-related experiences and needs. Healthcare providers should identify key management content at each stage to meet patients' multidimensional and diverse prevention and management needs, constructing individualized management plans oriented to CAT journey requirements.

Objective: To explore the effects of Vitamin K2 (VK2) on theaortic artery calciifcation and oxidative stress injury in experimental rats.
Methods: A total of 24 rats were divided into 4 groups:①Control group,②6-week calciifcation group,③12-week calciifcation group and④6-week calciifcation + 6-week VK2 group;n=6 in each group. The arterial calciifcation was induced by warfarin (WFN) treatment. The calcium nodule and deposition in rat’s theaortic artery were detected by Alizarin red staining and o-cresolphthalein complexone method, the reactive oxygen species (ROS) were measured by DHE probe staining and the morphological changes of mitochondria in smooth muscle cells were detected by transmission electron microscopy.
Results: Calciifcation nodule formed in both 6-week and 12-week calciifcation groups, the calciifcation deposition and ROS were higher than Control group,P<0.01. Compared with both calcification groups, the above indexes were decreased in 6-week calciifcation + 6-week VK2 group,P<0.01. Both calciifcation groups showed mitochondria swelling with unclear structure and cytoplasm vacuoles degeneration in vascular smooth muscle cells. The vascular smooth muscle cell volumes were similar between Control group and 6-week calcification + 6-week VK2 group, and no cytoplasm vacuoles degeneration was observed.
Conclusion: Warfarin induced aortic calciifcation is related to oxidative stress injury which may cause the ultra-micro structural damage in smooth muscle cells; VK2 may reduce the oxidative stress injury and improve the condition of vessel calciifcation in experimental rats.

Objective: To explore the effect of oxidative stress injury on the mechanism of vascular smooth muscle cell (VSMC) calciifcation induced by calcium and phosphorus in experimental rats.
Methods: The VSMC calcification was induced by incubating the cells with calcium chloride (CaCl2) andβ-sodium glycerophosphate (β-GP) for 8 days, and the cells were divided into 4 groups: ① Control group, ② Calcification group,③ Calciifcation+H2O2 group, ④ Calciifcation+catalase group. The calcium nodule formation and calcium deposition in VSMC were detected by Alizarin red staining and o-cresolphthalein complexone method, the reactive oxygen species (ROS) was detected by DCFH-DA probe staining and the protein expression of Runx2 was examined by Western blot analysis.
Results: Compared with Control group, Calciifcation group showed the higher ROS production, more calcium nodule and calcium deposition, higher Runx2 protein expression;while compared with Calciifcation group, the above indexes were even higher in Calciifcation+H2O2 group, P<0.05. The ROS production, calcium nodule, calcium deposition and Runx2 protein expression were lower in Calciifcation+catalase group than those in Calciifcation group and Calciifcation+H2O2 group, but still higher than that in Control group. The protein expression of Runx2 was similar between Calciifcation+catalase group and Control group, P>0.05.
Conclusion: CaCl2 andβ-GP treatment may induce VSMC calciifcation via activating ROS-Runx2 signal pathway in experimental rats.
