摘要：
The relationship between induced abortion(IA) and hypertensive disorders of pregnancy(HDP) is inconclusive. Few studies have been conducted in China. In order to clarify the association between previous IA and risk of HDP, including gestational hypertension(GH) and pre-eclampsia(PE), we performed a community-based prospective cohort study enrolling 5191 eligible nulliparous women in selected 2 districts and 11 towns of Liuyang from 2013 to 2015. Multivariable logistic regression was conducted to examine whether IA was associated with HDP, GH and PE. Of the gravidea, 1378(26.5%) had a previous IA and 258(5.0%) diagnosed with HDP, including 141(2.7%) GH and 117(2.3%) PE. The difference in the incidence of GH and PE between gravidae having one versus those with two or more IAs was minimal. After adjustment for maternal age, body mass index at first antenatal visit, education, virus infection and history of medical disorders, previous IA was significantly associated with HDP (OR = 0.67, 95%CI = 0.49 to 0.91) and PE (OR = 0.61, 95%CI = 0.38 to 0.97), but not with GH (OR = 0.73, 95%CI = 0.49 to 1.10). Additional adjustment for occupation, living area, anemia, gestational diabetes mellitus, psychological stress, conception climate and infant sex, multivariable analysis provided similar results. In conclusion, previous IA was associated with a lower risk of PE among nulliparous women.

摘要：
Purpose: To develop a multicultural nursing competence instrument for use in assessing undergraduate student nurses (SNs). Methods: This study enrolled 322 student nurses (SNs) employed at five hospitals in Hunan Province. The nurses were identified by the cluster sampling method. The items on the competence instrument were retained or deleted after analyzing their coefficient of variation, coefficient of correlation with the total score, t-test results. Reliability tests and correlation analysis were used to examine internal consistency, while exploratory factor analysis was used to determine construct validity. Results: After analyzing items, the final multicultural nursing competence instrument comprised a total of 49 items that evaluated five dimensions. The instrument showed good overall reliability (0.958), and the internal consistency of the five dimensions ranged from 0.884 to 0.952. Furthermore, the correlations among the five dimensions were statistically significant (P < 0.01). An exploratory factor analysis of the five dimensions showed that five items incorporated aspects of cultural cognition (factor loading range, 0.824-0.888), five items incorporated aspects of cultural attitude (factor loading range, 0.629-0.815), twenty-two items involved cultural knowledge (factor loading range, 0.587-0.792), seven items incorporated aspects of cultural skills (factor loading range, 0.743-0.860), and 10 items involved cultural encounters (factor loading range, 0.522-0.909). Conclusion: The multicultural nursing competence instrument for SNs demonstrated good reliability and validity, and can be utilized in nursing education programs and research.

摘要：
Introduction: Telomeres are DNA protein structures at the end of chromosomes and are linked to the physical aging process. The improvement of quality of life is closely associated with aerobic exercise, and the dynamic effects of exercise on physiology and psychology are evident with aging. Tai Chi is popularly practiced in China. However, findings on the effects of Tai Chi on telomerase activity (TA) in peripheral blood mononuclear cells, and gerotranscendence (GT), as well as the association of TA and GT with Tai Chi, have been inconsistent. Purpose: This study aims to assess TA in peripheral blood mononuclear cells, GT, and the associations between them. The associations among these variables are determined during six months of Tai Chi intervention among Chinese middle aged and elderly adults. Methods: TA assessment was obtained by TE-ELISA (human telomerase-enzyme linked immunosorbent assay), and GT was measured at the baseline level after six months of Tai Chi intervention. Results: TA increased significantly in the Tai Chi group from 23.75 +/- 3.78 u/mmol (preintervention) to 26.31 +/- 2.93 u/mmol (after 6 months) (p < 0.05). Compared with the TA in the control group, the TA in the intervention group was statistically significant after six months (p < 0.05). Compared with the GT in the control group, the GT in the intervention group improved significantly after six months (p < 0.05). TA and GT had a positive correlation (r = 0.325, p < 0.01). Conclusion: Our data illustrated that Tai Chi had a protective effect on TA and might improve the GT in Chinese middle aged and elderly adults. The TA increased with the increasing GT in Chinese middle aged and elderly adults. Copyright (C) 2016, Chinese Nursing Association. Production and hosting by Elsevier B.V.
