The USA (N = 319) and University of Pennsylvania (N = 38) were the most productive country and institution respectively. Author co-citation and bibliographic-coupling network analysis identified that Aiken, Kramer, Laschinger, Schmalenberg, Lake and Johantgen were the major contributors and leaders in this field. According to the research content of the main contributors and keyword co-occurrence analysis result, the research focus could be divided into four parts: the mechanism leading to the outcomes differences for magnet hospital, the evidence-based practice, the outcomes comparison between magnet hospital and non-magnet hospital and the practice environment. CONCLUSION: This bibliometric study offered a comprehensive overview of current study status of magnet hospital and this area has been drawn increasing attention over the years. However, the research on magnet hospital is still relative limited and needs to be paid more attention, especially in developing countries. IMPACT: This study showed the most contributed countries, journals, institutions, authors and the main themes related to magnet hospital, which would help researchers find potential partners, optimize and deepen future research, such as enhancing the magnet hospital research in developing countries, improving the evidence-based research and considering the impact caused by different culture. Furthermore, this study can also give suggestions for magnet hospital policy makers.

Spectroscopic investigation and comprehensive analysis of the polychrome clay sculpture of Hua Yan Temple of the Liao Dynasty.

This article shows the investigation results of the polychrome clay sculptures in Hua Yan Temple of the Liao Dynasty in Datong, China. The mineral pigments, adhesive and painting techniques used in these cultural relics were systematically analyzed in this project. Optical microscope (OM), Scanning electron microscope coupled with an energy-dispersive X-ray spectroscopy (SEM-EDS), micro-Raman, Fourier transform infrared spectrometer (FT-IR) and Pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) analyses were selected as scientific micro-destructive analytical methods. The results show that the pigments in the polychrome clay sculptures include cinnabar, lead red, malachite, atacamite, azurite, orpiment and gold. Meanwhile, the presence of nitrogen-containing substances and glue-marker characteristic pyrolysis products clearly indicates that the adhesive used in most of the polychrome clay sculptures was glue-protein. Additionally, the combination of heat-bodied tung oil and glue-protein was also found in the golden areas.

Collaborative networks and thematic trends of research on the application of complementary and alternative medicine in cancer patients: A bibliometric analysis.

BACKGROUND: and purpose: Complementary and Alternative Medicine(CAM) has been greatly used in cancer patients. This research aimed to explore the research priorities of CAM for cancer patient's treatment. METHODS: Web of Science(WoS), HistCite, BibExcel, GunnMap and VOSviewer were used to extract and visualize information. RESULTS: 2768 articles published in 789 journals were indexed in the WoS from 1989 to 2018. The USA(n = 1009) and Technion-Israel Institute Technology(n = 58) were the most prolific country and institution, respectively. Keywords co-occurrence analysis indicated that the research hotspots around the world formed five clusters, so did the author co-citation analysis. The research priorities of the top-five countries, the top-three prolific authors and the co-citation core authors were also discussed, which reveals the differences and similarities among them. CONCLUSION: This study delineates a framework for better understanding the situational use of CAM in cancer patients, which could help health care workers to prioritize and organize future research.

Comparisons of the restoring and reinforcement effects of carboxymethyl chitosan-silk fibroin (Bombyx Mori/Antheraea Yamamai/Tussah) on aged historic silk.

This work presents the results of the reinforcement effects of regenerated silk fibroin solutions (SF) of Bombyx-Mori, Antheraea-Yamamai and Tussah on aged historic silk. Furthermore, Carboxymethyl-chitosan (CMC) was utilized as reinforcement and antibacterial filler to further improving the mechanical properties and antibacterial effects. To clarify the rationale behind this process, comprehensive characterization was applied, and a speculative explanation was provided. The results showed that Bombyx-mori and Tussah have better restoring effects than Antheraea-yamamai. CMC has good compatibility to the SF, and the addition of CMC has significantly contributed to the improvement the mechanical properties and thermal stability of the restored silk, which is due to the formation of chemical bonding, strong hydrogen bonding and the construction of polymer network structure. The enhancement of crystallinity and reduction of ß-turns structure indicate that the micro-defects in the crystallization zone of the aged silk has been restored, and the ordered arrangement in the long-range ordered structure has been improved within a certain range. It was found that the CMC acted as antifungal agents when introduced on the aged historic silk, reducing the growth of Aspergillus niger, Aspergillus flavus and Paecilomyces variotii to a certain extent, which were commonly found in storage areas of libraries.

Analysis on the Composition/structure and Lacquering Techniques of the Coffin of Emperor Qianlong Excavated from the Eastern Imperial Tombs.

This article presents the results of an investigation on the coffin of Emperor Qianlong excavated from the Eastern Imperial Tombs of the Qing Dynasty in Zunhua, China. The composition, structure and lacquering techniques used in the manufacturing process were analyzed in this project. Stereoscopic Microscopy, SEM-EDS, XRD, FTIR, Raman, Double-shot Py-GC/MS were used as scientific analytical methods. The results show that the structure of the coffin body consists of a wooden body layer, a lacquer ash layer and a lacquer film pigment layer. The lacquer ash layer consists of nine stucco layers and ten fiber layers on top of each other in an alternating order. The lacquer film pigment layer consists of mineral pigments, lacquer sap, animal gelatin, drying oil, quartz sand and proteinaceous materials. Pigments used in the lacquer film include calcite white, carbon black, cinnabar red and gold. The presence of three distinctive catechols along with the other catechols' and phenols' profiles in the lacquer film matrix clearly indicate the species of the lacquer tree was Rhus. Vernicifera. Several distinctive lacquering techniques that improved the coffin body's stability and mechanical strength were identified in the investigation, including the "wan lacquering", "painting lacquer above the gold" and "Jin Jiao".
