基于OA及免费全文链接的期刊影响力指数优势

【目的】 为开放获取政策的制定提供理论参考,给学术搜索引擎免费全文链接的建设提供依据。【方法】 对图书馆、情报与文献学领域的26种中文社会科学引文索引来源期刊的开放获取状况与免费全文链接情况进行调查。根据期刊的开放获取状态和免费全文链接获得程度将期刊分为4类,分别在不同的时间视窗下比较4类期刊的各项评价指标的变化趋势,并进行相关性分析。【结果】 所选的26种期刊的开放获取程度为61.5%,这些期刊在百度学术中平均每篇论文拥有2.17个免费全文链接。开放获取和有高免费全文链接获得程度的期刊在不同时间视窗影响力指数下的表现都较占优势。【结论】 期刊开放获取和有较多的免费全文链接有助于期刊的被引用和影响力的提升。     

Imbalance of coagulation and fibrinolysis can predict vascular access failure in patients on hemodialysis after vascular access intervention

Objective

For patients with end-stage renal disease on hemodialysis, the durability of vascular access (VA) is still far from optimal, and access survival after intervention for access failure is an important aspect. Procoagulant status is a leading cause of access failure. Coagulation-fibrinolysis imbalance can occur in hemodialyzed patients, but the influence of the imbalance has not been fully elucidated.

Publishing in open access era: focus on respiratory journals

We have entered an open access publishing era. The impact and significance of open access is still under debate after two decades of evolution. Open access journals benefit researchers and the general public by promoting visibility, sharing and communicating. Non-mainstream journals should turn the challenge of open access into opportunity of presenting best research articles to the global readership. Open access journals need to optimize their business models to promote the healthy and continuous development.     

儿童植入式静脉输液港技术的应用

目的为需要长期反复化疗的血液系统肿瘤及恶性实体瘤患儿寻找合适的血管通路。方法 2011年12月~2014年6月我科为33例恶性肿瘤患儿植入输液港。通过术前健康宣教、术后精心护理,掌握输液港操作流程,做好输液港管理和维护。结果本组33例患儿均一次植入成功,1例患儿在化疗的第3个疗程发生感染,予以取港;2例患儿化疗完成予以取港,其余均在治疗中,无并发症发生,家长满意。结论植入式静脉输液港是一种较新的输液管路技术,可为长期反复化疗患儿提供可靠的静脉通道,避免长期反复外周静脉穿刺的痛苦,术后生活不受影响,提高了患儿的生活质量,减轻了家长的心理负担,适用于恶性肿瘤患儿的化疗。     

Inequality in oral health‐related quality of life before and after a major subsidization reform

In Finland, a dental subsidization reform, implemented in 2001–2002, abolished age restrictions on subsidized dental care. We investigated income‐related inequality in oral health‐related quality of life (OHRQoL) and its determinants among adult Finns before and after the reform. Three cross‐sectional postal surveys, focusing on perceived oral health and the use of dental services among people born before 1971, were conducted in 2001 (n = 2,046), 2004 (n = 1,728), and 2007 (n = 1,560). Five measures, based on the Oral Health Impact Profile‐14, were used as indicators of OHRQoL. Income‐related inequality and associated factors were analysed using the concentration index and its decomposition. Prevalence, extent, and severity of oral health impacts were slightly lower in 2007 than in 2001. The oral health impacts were concentrated, at all study time points, among individuals with lower income. Most of the inequality was related to self‐perceived general health, tooth loss, and income. Contributions of time since the last dental visit and satisfaction with the last treatment period to the inequality decreased from 2001 to 2007. However, the contributions of these factors were already small (10–20%) in 2001. In general, OHRQoL improved slightly; however, no clear or dramatic change in inequality in OHRQoL was seen after the reform.
