RESUMEN
This paper discussed the characteristics and influencing factors of the body image of oral cancer patients after surgery, and put forward targeted intervention strategies for medical social work, so as to provide clinical pathway reference for the body image adaptation of oral cancer patients. By reviewing relevant studies at home and abroad, it was found that the body image of oral cancer patients has the following characteristics: low level, serious negative impact, lack of psychosocial intervention, and is affected by disease factors, personal trait factors, support system factors, and social situational factors. In this regard, it was proposed to use the professional methods of social work to carry out psychosocial intervention and provide information support for disease factors; according to the individual trait factors, the intervention should be carried out from three aspects: psychological crisis intervention, self-cognitive acceptance, and guidance and encouragement from the advantage perspective; in view of social support system factors, it was suggested that not only pay attention to the benign interaction of existing support systems, but also actively assist patients to expand new support systems; for social situational factors, medical social workers should actively play the role of popular science education and policy advocacy.
RESUMEN
As an important part of the medical supply-side reform, grading diagnosis and treatment is the core objective of various medical services carried out by medical institutions at all levels. This paper proposed that tertia-ry hospitals should promote the construction of grading diagnosis and treatment from three aspects of multi-sited practice of physicians, construction of medical alliance and functional orientation planning. On this basis, this pa-per mainly discussed the service function of medical social work involved in grading diagnosis and treatment mode in tertiary hospitals.
RESUMEN
Practice teaching and supervision has become an important part of hospital social work practice, and the handling and response to internship dilemma is the problem that every institution supervisor needs to think a-bout. Based on qualitative interview and text analysis, starting from the needs of intern, this paper found that students of social work major mainly faced the following dilemma in the process of hospital practice: role adapta-tion, the dilemma of professional practice, the dilemma of ethical relationship and practice burnout and so on. Combined with their own supervision experience, this paper put forward coping methods.
RESUMEN
BACKGROUND:Femoral neck fracture is mainly fixed by three inverted triangle cannulated screws. Scholars have proposed to add a cannulated screw to enhance the fixation strength of femoral neck fracture of Pauwels III type based on three cannulated screw fixation, but the stability is not verified. OBJECTIVE:To analyze the biomechanical stability and stress of the three and four cannulated screws for the treatment of the Pauwels III femoral neck fractures. METHODS:The CT imaging results of the fourth generation of artificial bone sawbones were imported into the Mimics software wherein a three-dimensional finite element model of the proximal femur was prepared and introduced in the 3-matic software. Models of middlesegment of femoral neck with Pauwels III fractures were established. Cannulated screw models were established with UG 8.0 software and introduced in the fractures models. Finally, finite element models of Pauwels III femoral neck fractures fixed with three and four screws were established. In the same condition, an axial load of 411 N was applied on the femoral head with Abaqus software. The displacement of two markers of the broken ends and internal fixation system Von Mises stress distribution were compared between the two models. RESULTS AND CONCLUSION:(1) The displacement was 0.42 mm in three screws model, and 0.17 mm in the four screws model. (2) Von Mises stress peak was 547 MPa and 27.8 MPa in both models. The peak value was lower in models of fourscrews than that of three screws. Stress concentration position was at the fracture site in both models. The stress range of models of four screws was more extensive and scattered. (3) Finite element analysis results demonstrated that four-screw implantation for Pauwels III femoral neck fractures had strong anti-shearing force and biomechanical stability. Clinical advantages need further clinical comparative study.
