摘要：
Purpose: We investigated the impacts of plasma levels of magnesium (Mg), zinc (Zn), calcium (Ca), iron (Fe), copper (Cu), selenium (Se), and chromium (Cr) on GDM risk and the potential mediation effect of blood glucose levels on the relationship between trace elements and GDM risk. Methods: This nested case-control study was based on data from a birth cohort study conducted in Wuhan, China in 2013-2016. A total of 305 GDM cases and 305 individually-matched controls were included in the study. Conditional logistic regression models were used to estimate the associations between plasma trace element concentrations and GDM risk. A mediation analysis was conducted to explore whether blood glucose levels act as a mediator between trace element levels and GDM risk. Results: An IQR increment in plasma levels of Fe and Cu was associated with a significant increase in GDM risk [OR = 2.04 (95 % CI 1.62, 2.57) and OR = 1.52 (95 % CI 1.25, 1.82)], respectively. On the other hand, an IQR increment in plasma levels of Zn and Ca was associated with a significant decrease in GDM risk [OR = 0.55 (95 % CI 0.43, 0.71) and OR = 0.72 (95 % CI 0.56, 0.92)], respectively. The mediation analysis showed significant mediation of the association between Cu and GDM risk via the FBG (%mediated: 19.27 %), 1 h-PBG (12.64 %), 2h-PBG (28.44 %) pathways. Conclusions: Plasma levels of Zn and Ca were negatively associated with GDM risk, while Fe and Cu were positively associated. Blood glucose levels act as a mediator between plasma trace element exposures and GDM risk.

摘要：
Objectives:To describe the characteristics and relationships of social isolation and health promoting behaviors of Chinese older adults with different health statuses.Methods:Totally 485 older adults were recruited.They were divided into three groups based on their health status:healthy group (n-72),group with one disease (n =183) and group with multimorbidity(n =230).Lubben Social Network Scale-6 and Health-Promoting Lifestyle Profile Ⅱ were used to measure their social isolation and health-promoting behaviors,respectively.Results:Among the aged with one disease or multimorbidity,30.6％ (56/183) and 31.7％ (73/230) were socially isolated,respectively,based on the score of the Lubben Social Network Scale-6.The three groups differed significantly in health-promoting behaviors and scores on several subscales.The group with multimorbidity exhibited more social isolation and fewer health-promoting behaviors than other groups.Social isolation was among the factors adversely affecting health-promoting behaviors in older adults.Conclusions:Health care providers should help older adults with multimorbidity preserve the remaining abilities to improve health-promoting behaviors.Meanwhile,it is important to support healthy older adults to increase self-responsibility to achieve healthy aging.

摘要：
Objectives: This research aimed to examine health care workers' grief counseling for bereaved families of Coronavirus disease 2019 (COVID-19) victims in China. Our research may provide a new opportunity to stimulate development of grief counseling in China.Methods: A cross-sectional survey was conducted with 724 health care workers selected by convenience sampling from seven hospitals in Wuhan. Data collection tools included a sociodemographic questionnaire, the skills of grief counseling scale (SGCS), and the attitudes of grief counseling scale (AGCS).Results: The average SGCS score was 18.96±4.66, whose influencing factors consisted of sense of responsibility, frequency of contact with bereaved families, and relevant training (P<0.05). The average AGCS score was 33.36±8.70, whose influencing factors consisted of other grief counseling skills, communication skills, education background, and relevant training (P<0.05).Conclusions: The skills and attitudes toward grief counseling among health care workers combating COVID-19 were at a lower level in Wuhan, China, indicating the need to build a comprehensive grief counseling system, establish a standardized training course, and strengthen the popularization of grief counseling services to the public.

目的:分析发表在中国知网（China National Knowledge Infrastructure,CNKI）上的关于我国胃癌患者照顾者研究的发展动态,为今后的深入研究提供参考。方法:以中国知网（CNKI）为数据来源,选择知网下的文献数据库,在输入检索条件下的"主题"字段输入"胃癌"或者"照顾者",在"篇名"字段输入"照顾者"或者"家属","主题"与"篇名"之间用"并且"连接,选择"模糊"词频进行检索,对检索到的第一作者为中国大陆的文献进行分析。结果:共检索出65篇文献,选择符合纳入条件的21篇文献进行研究分析。结论:来自全国各地的研究者都越来越关注胃癌患者的照顾者,其中以描述性研究居多。在今后的研究中应该进一步拓展相关研究的广度与深度,探讨某种合适又高效的干预方式对照顾者进行干预后以达到提高患者的生活质量、促进医患关系和谐的目的。
摘要：
Aim To identify the intention of Chinese pregnant women to undertake physical activity (PA) using the theory of planned behaviour. Design A cross-sectional survey. Methods From April - October 2017, a cross-sectional questionnaire was completed by 746 pregnant women from the Health Birth Cohort in Wuhan, China. The theory of planned behaviour variables as well as sociodemographic characteristics was recorded, and the Pregnancy PA Questionnaire was together used to assess their PA during pregnancy. Results Only 11.3% of the women met the international guideline. The intention to undertake PA was found it to be positive in 63.9% of pregnant women. Structural equation modelling analysis revealed that behavioural attitudes, subjective norms, and perceived behavioural control (PBC) influenced PA by directly influencing the behaviour intention. Both behavioural attitude and subjective norms influenced PA by indirectly affecting the behaviour. Overall, the model described 60% variance of the behavioural intention to undertake PA during pregnancy. Conclusion PBC was confirmed to be a prominent factor in determining behavioural intention to undertake PA during pregnancy. Pregnant women should be helped and appropriately guided by health providers to overcome barriers to PA. Effect This study investigates the effect of perceived behavioural control (PBC) on the intention to undertake physical activity (PA). The findings suggest that nurses' and midwives' attention should be focused on how to promote the improvement of perceived behavioural control ability of pregnant women to improve pregnant women's PA intention. The attitude of pregnant women on taking up PA and their ability to control behaviours can be improved with support from family or healthcare providers.
