目的评价江苏省疾病预防控制中心脊髓灰质炎(脊灰)实验室所用细胞系对脊灰病毒的敏感性,制备江苏省脊灰实验室的标准毒株(QC)。方法采用96孔微量培养板滴定法。结果江苏省脊灰实验QC3次独立的细胞敏感性实验结果的滴度波动为±0.5 log 10CCID50,同时用中国疾病预防控制中心病毒病预防控制所国家脊灰实验室提供的已知滴度的Sabin参考株(China Sabin Test Reference Strain;CSTRS)做平行对照,CSTRS株3次滴度结果与其本身提供的参考值相比较,其滴度波动也均为±0.5细10CCID50。结论江苏省脊灰实验室QC结果符合实验要求,脊灰实验室所用细胞系对脊灰病毒的敏感性未下降。是敏感、有效的。 相似文献

Although studies have demonstrated that females experience more HIV-related stigma than males do, questions remain regarding the different dimensions of the stigma (i.e., perceived versus internalized) in China. The present study investigated gender differences in perceived and internalized HIV-related stigma, taking into account the potential influence of education. The study was conducted between October 2011 and March 2013. A total of 522 people living with HIV (PLH) were recruited from Anhui Province, China. The PLH participated in a survey using the Computer Assisted Personal Interview (CAPI) method. The gender differences in perceived and internalized HIV-related stigma were calculated with and without stratifying by education level. Female participants had significantly less education than the male participants. No significant difference was observed between females and males with respect to perceived stigma. However, females reported significantly higher internalized stigma than males did (p < .001). When socio-demographic characteristics were controlled, the gender difference in internalized stigma remained significant among educated participants (p = .038). The findings suggested that gender differences in HIV-related stigma were primarily found for internalized stigma. Heightened intervention efforts are encouraged to reduce internalized HIV-related stigma, particularly among female PLH in China and other regions with similar gender dynamics. 相似文献

【目的】 通过统计分析“中国科技期刊登峰行动计划”入选期刊的发展现状,为优化资助机制、培育世界一流科技期刊提供参考。【方法】 基于Web of Science的JCR评价数据,运用文献计量法和深度访谈法对入选期刊发展现状和存在问题进行分析并提出建议。【结果】 入选期刊影响因子总体提升不明显,存在片面追求影响因子的倾向;资助的“解渴”“解困”作用明显,但由于期刊国际化办刊思路不清晰,谋划不足,撬动期刊实现世界一流建设目标的杠杆作用发挥得并不充分。【结论】 资助方应通过注重资助效果评估和反馈,清晰资助导向,促进资助效果形成良性循环。期刊方应深入理解“世界一流科技期刊”的建设内涵,把握规律,探索模式,积极进行国际化办刊实践,提升期刊国际影响力。 相似文献

Erdheim-Chester disease (ECD) is a rare non-Langerhans histiocytosis and inflammatory myeloid neoplasm with poor prognosis. Symmetric long bone osteosclerosis occurs in nearly all patients, but other organs are often involved. Coronary artery involvement is rare, but was encountered in a patient who experienced angina. Radiologic presentation and histologic findings were consistent with diagnosis of ECD. A soft-tissue mass was found surrounding the right atrium, ascending aorta, and all branches of coronary artery. Interferon-alfa treatment was successful. In conclusion, we recommend coronary artery computed tomography angiography for cardiovascular evaluation of ECD and interferon-alfa to treat ECD. 相似文献

BackgroundIn contrast to China’s giant health information technology (HIT) market and tremendous investments in hospital information systems the contributions of Chinese scholars in medical informatics to the global community are very limited. China would like to have a more important position in the global medical informatics community.ObjectiveA better understanding of the differences between medical informatics research and education in China and the discipline that emerged abroad will better inform Chinese scholars to develop right strategies to advance the field in China and help identify an appropriate means to collaborate more closely with medical informatics scholars globally.MethodFor the first time, this paper divides the evolution of medical informatics in China into four stages based on changes in the core content of research, the educational orientation and other developmental characteristics. The four stages are infancy, incubation, primary establishment and formal establishment. This paper summarizes and reviews major supporting journals and publications, as well as major organizations. Finally, we analyze the main problems that exist in the current disciplinary development in China related to medical informatics research and education and offer suggestions for future improvement.ConclusionsThe evolution of medical informatics shows a strong and traditional concentration on medical library/bibliographic information rather than medical (hospital information or patient information) information. Misdirected-concentration, a lack of formal medical informatics trained teaching staff and mistakenly positioning medical informatics as an undergraduate discipline are some of the problems inhibiting the development of medical informatics in China. These lessons should be shared and learned for the global community. 相似文献

热疗是继手术、放疗、化疗及生物治疗之后的第五种肿瘤治疗手段,亦是重要的肿瘤辅助治疗方法之一,临床应用无毒、安全,也称为绿色治疗。近年来,肿瘤的热疗越来越受到人们的重视,全国许多地市级医院甚至县级医院都普遍开展了肿瘤的热疗,并取得了很好的治疗效果。目前国内外尚无肿瘤热疗的指南和规范,为了指导和规范肿瘤热疗的临床应用,更好地为肿瘤患者服务,特制定中国肿瘤热疗临床应用指南,就浅部热疗、深部热疗、全身热疗及体腔灌注热疗的适应证、禁忌证、操作程序与方法、注意事项、热疗的疗效评价及随访等进行了全面详细地阐述,供肿瘤热疗治疗领域同仁们参考。 相似文献
