Objectives: Professional identity and self-efficacy are important for the education and career develop-ment of students. However, how to improve these factors among Chinese nursing students needs further study. This quasi-randomized control trial was designed to explore the effect of medical documentaries on professional self-efficacy and identity among nursing students in Chinese technical schools. Methods: A total of 277 nursing students were enrolled in this study and divided into an experimental group (n = 135) and a control group (n = 142). The experimental group was invited to watch Chinese medical documentaries, whereas the control group remained on a waiting list. A self-designed general questionnaire, along with professional identity and professional self-efficacy questionnaires, was completed by the nursing students. Results: No significant change in professional self-efficacy was observed (-3.55 ± 14.23, P=0.173) in the experimental group, while professional identity significantly declined (-6.24 ± 12.85, P = 0.002) after the intervention. No significant change was found in the two aspects in the control group. Conclusion: Medical documentaries negatively affect professional identity but do not affect professional self-efficacy. Further researches should be conducted to explore the real reasons.

This review investigates the current application limitations of Mg and Mg alloys. The key issues hindering the application of biodegradable Mg alloys as implants are their fast degradation rate and biological consideration. We have discussed the effect of some selected alloying element additions on the properties of the Mg-based alloy, especially the nutrient elements in human （Zn, Mn, Ca, St）. Different grain sizes, phase constituents and distributions consequently influence the mechanical properties of the Mg alloys. Solution strengthening and precipitation strengthening are enhanced by the addition of alloying elements, generally improving the mechanical properties. Besides, the hot working process can also improve the mechanical properties. Combination of different processing steps is suggested to be adopted in the fabrication of Mg-based alloys. Corrosion properties of these *** alloys have been measured in vitro and in vivo. The degradation mechanism is also discussed in terms of corrosion types, rates, by- products and response of the surrounding tissues. Moreover, the clinical response and requirements of degradable implants are presented, especially for the nutrient elements （Ca, Mn, Zn, Sr）. This review provides information related to different Mg alloying elements and presents the promising candidates for an ideal implant.

The Ni9.3W alloy with no ferromagnetism and high yield strength is one of the most promising textured substrate materials for coated conductors, but its low stacking fault energy makes it difficult to obtain a strong cube texture by traditional rolling methods and recrystal- lization anneals. This paper introduces four-time static recoveries during the rolling process. Rolled tapes with 80 μm in thickness were obtained by applying various deformation sequences between static recoveries to study their effects on the cube texture formation in Ni9.3W alloy substrates. The results show that rising gradient deformation sequence is an advantageous way to obtain a higher amount of cube texture, its content increases by 29.2% compared to that of traditional deformation sequence. The effect of the new recrystallization annealing process on the cube texture formation was analyzed. It is shown that the cube texture content increases with anneal temperature increasing in one-step anneal, but decreases again at higher anneal temperature. Two-step anneal could effectively improve the cube texture content, which could be further enhanced by extending holding time during the first-step anneal. However, too long holding time leads to the decrease in cube texture content. Finally, Ni9.3W alloy substrates with a cube texture content of -90.0 vol% （〈15°） are obtained by optimized two-step anneal.
