ABSTRACT
INTRODUCTION: Intrahepatic cholangiocarcinoma (ICC), which is difficult to diagnose and is usually fatal due to its late clinical presentation and a lack of eï¬ective treatment, has risen over the past decades but without much improvement in prognosis. OBJECTIVE: The study aimed to investigate the role of apatinib that targets vascular endothelial growth factor receptor-2 (VEGFR2) in ICC. METHODS: MTT assays, cell scratch assays, and tube formation assays were used to assess the effect of apatinib on human ICC cell line (HuCCT-1) and RBE cells proliferation, migration, and angiogenic capacity, respectively. Expression of vascular endothelial growth factor (VEGF), VEGFR2, signal transducer and activator of transcription factor 3 (STAT3), pSTAT3, and hypoxia inducible factor 1 subunit alpha (HIF-1α) pathway proteins was assessed using Western blotting and mRNA expression analysis in HuCCT-1 was performed using RT-qPCR assays. The pcDNA 3.1(-)-VEGFR2 and pcDNA 3.1(-)-HIF-1α were transfected into HuCCT-1 and RBE cells using Lipofectamine 2,000 to obtain overexpressed HuCCT-1 and RBE cells. RESULTS: We found that apatinib-inhibited proliferation, migration, and angiogenesis of HuCCT-1 and RBE cells in vitro in a dose-dependent manner. We also proved that apatinib effectively inhibits angiogenesis in tumor cells by blocking the expression of VEGF and VEGFR2 in these cells. In addition, we demonstrated that apatinib regulates the expression of STAT3 phosphorylation by inhibiting VEGFR2. Finally, we showed that apatinib regulates ICC angiogenesis and HIF-1α/VEGF expression via STAT3. CONCLUSIONS: Based on the above findings, we conclude that apatinib inhibits HuCCT-1 and RBE cell proliferation, migration, and tumor angiogenesis by inhibiting the VEGFR2/STAT3/HIF-1α axis signaling pathway. Apatinib can be a promising drug for ICC-targeted molecular therapy.

Positive perceptions of patient safety culture are associated with lower rates of adverse events, but they have not been widely established in many health care organizations. The purpose of this study is to examine the impacts of a safety culture training program (SCTP) on enhancing the perceptions of patient safety in nurse managers. This was a quasi-experimental design. 83 nurse managers were recruited from five randomly selected 2nd level hospitals. Sixty-seven nurse managers received training under the educational SCTP. The Hospital Survey on Patient Safety Culture (HSPSC) and Chinese Safety Attitudes Questionnaire (C-SAQ) were administered just before and six months after the educational program. The data of hospital-acquired pressure ulcers, patient falls, and unplanned extubations were collected. The total positive scores of HSPSC were significantly improved and four dimensions of C-SAQ significantly increased six months after SCTP. The rate of patient falls and rate of hospital-acquired pressure ulcers decreased significantly six months post SCTP. In conclusion, nurse manager participation in a SCTP can enhance the perceptions of patient safety and reduce the rates of adverse events. More rigorous trials with larger numbers of participants and a control group are needed to strengthen the conclusions.

OBJECTIVES: to investigate the quality of life and the associated factors on left behind elderly in rural China. METHOD: the research was conducted cluster sampling to select 456 elderly left behind when family members migrated out of rural China to participate in a cross-sectional study by completing a general data questionnaire and Quality of Life questionnaire. RESULTS: 91.5% of the elderly requested psychological counseling and education. For the elderly, scores for mental health (39.56±13.73) were significantly lower compared with Chinese standard data (61.6±13.7) (P<0.001). Age, chronic disease type, gender, residence pattern and economic support from children were the main psychological factors influencing this population. CONCLUSION: mental health is the most important factor influencing quality of life of elderly left behind when family members migrated out of rural China. Our study suggested a need to widely establish a general practitioner team for psychological intervention for improving rural elderly people's Quality of Life level, especially in the psychological domain.

OBJETIVOS: investigar a qualidade de vida e fatores associados de idosos deixados para trás na China rural. MÉTODO: foi realizada amostragem por conglomerado para selecionar 456 idosos deixados para trás quando os membros da família emigram da China rural. Este é um estudo transversal com preenchimento de um questionário de dados gerais e de qualidade de vida. RESULTADOS: 91,5% dos idosos convidados solicitaram aconselhamento e educação psicológicos. Para os idosos, os escores de saúde mental (39,56±13,73) foram significativamente menores em comparação aos dados padrões chineses (61,6±13,7) (p<0,001). A idade, tipo de doença crônica, gênero, tipo de moradia e suporte econômico dos filhos foram os principais fatores psicológicos que influenciaram essa população. CONCLUSÃO: a saúde mental é o fator mais importante que influencia a qualidade de vida de idosos deixados para trás quando os familiares emigraram da China rural. Este estudo sugere a necessidade de criação de ampla equipe de generalistas para intervenção psicológica, com o intuito de melhorar o nível de qualidade de vida de idosos de áreas rurais, especialmente no domínio psicológico. .
OBJETIVOS: investigar la calidad de vida y los factores asociados a los adultos mayores que se quedan en las zonas rurales de China. MÉTODO: la investigación se realizó por medio de muestreo por conglomerados para seleccionar 456 adultos mayores que se quedaron cuando los miembros de la familia emigraron de zonas rurales de China, para participar en un estudio de corte transversal, completando un cuestionario de datos generales y cuestionario de calidad de vida. RESULTADOS: el 91.5% de los adultos mayores solicitó asistencia psicológica y educación. Para los adultos mayores, las puntuaciones de salud mental (39.56±13.73) fueron significativamente más bajos en comparación con los datos estándar de China (61.6±13.7) (p<0.001). La edad, el tipo de enfermedad crónica, el género, el patrón de residencia y el apoyo económico de los hijos fueron los principales factores psicológicos que influencian esta población. CONCLUSIÓN: la salud mental es el factor más importante que influye la calidad de vida de los adultos mayores que se quedan cuando los miembros de la familia emigran de las zonas rurales de China. Nuestro estudio sugiere la necesidad de establecer ampliamente un equipo médico general para la intervención psicológica para mejorar el nivel de la Calidad de Vida de la población rural de edad avanzada, sobre todo en el dominio psicológico. .
