This study proposes a bile duct stent based on indirect 3D printing technology. Four ratio materials were synthesized from lactic acid (LA) and glycolide (GA) monomers by melt polymerization: PLA, PLGA (70:30), PLGA (50:50), and PLGA (30:70). The four kinds of material powders were preliminarily degraded, and the appearance was observed with an optical microscope (OM) and a camera. The weight and appearance of the four materials changed significantly after four weeks of degradation, which met the conditions for materials to be degraded within 4–6 weeks. Among them, PLGA (50:50) lost the most—the weight dropped to 13.4%. A stent with an outer diameter of 10 mm and an inner diameter of 8 mm was successfully manufactured by indirect 3D printing technology, demonstrating the potential of our research. Then, the degradation experiment was carried out on a cylindrical stent with a diameter of 6 mm and a height of 3 mm. The weight loss of the sample was less than that of the powder degradation, and the weight loss of PLGA (50:50) was the largest—the weight dropped to 79.6%. The nano-indenter system measured the mechanical properties of materials. Finally, human liver cancer cells Hep-3B were used to conduct in vitro cytotoxicity tests on the scaffolds to test the biocompatibility of the materials. A bile duct stent meeting commercial size requirements has been developed, instilling confidence in the potential of our research for future medical applications. [ABSTRACT FROM AUTHOR]

This report describes our experience providing nursing care between 7th October and 7th November 2016 to a homosexual male who repeatedly engaged in stress-related suicide attempts and self-harm. Information was collected using comprehensive nursing assessment, observation, and interviews and the health problems of ineffective coping and disabled family coping were identified. Because of affection-related distress and the lack of recognition of his gender orientation by his family, the client engaged repeatedly in self-harm and attempted suicide on several occasions in order to cope with the self-perceived unbearable stress and stressful situations. The authors provided nursing care based on Watson's theory of human caring. We fulfilled the nature of caring, prompted respect and acceptance, and established a therapeutic, interpersonal relationship. We also adopted the concept of suicide intervention, and used the protective factors as the main coping strategies. These approaches allowed the client to acknowledge the events and reactions that may trigger his suicidal ideas, to develop better self-reflection and impulse control, and to mitigate the ideas and behaviors related to suicide and self-harm. Because constant conflicts between the client and his parents hampered a harmonious family relationship, we adopted family-centered care in order to enhance family resilience, which created room for mutual learning and development and reconstructed a healthy family relationship. Our successful results with this case encouraged our writing this paper in order to share this nursing experience with caregivers facing similar client situations and needs.
