Methods for Examination an Explanted Coronary Sinus Lead Stabilized with a Coronary Stent

The aim of our investigation was to test the suitability of a novel method for the analysis of the integrity of an explanted pacemaker lead stabilized by a stent. A coronary sinus lead has been explanted 27 months after implantation and has been examined by optical‐, confocal‐, x‐ray‐, and scanning electron microscopy. Several surface injuries were found on the insulation. Based on the surface characteristics, it is possible to define and differentiate the source of damages as well as to measure the extent of injuries. Impedance of the explanted lead has also been measured and electronic integrity has been verified. (PACE 2013; 36:e27–e30)

Induction of bone formation in biphasic calcium phosphate scaffolds by bone morphogenetic protein‐2 and primary osteoblasts

Bone tissue engineering strategies mainly depend on porous scaffold materials. In this study, novel biphasic calcium phosphate (BCP) matrices were generated by 3D‐printing. High porosity was achieved by starch consolidation. This study aimed to characterise the porous BCP‐scaffold properties and interactions of osteogenic cells and growth factors under in vivo conditions. Five differently treated constructs were implanted subcutaneously in syngeneic rats: plain BCP constructs (group A), constructs pre‐treated with BMP‐2 (group B; 1.6 µg BMP‐2 per scaffold), seeded with primary osteoblasts (OB) (group C), seeded with OB and BMP‐2 (group D) and constructs seeded with OB and pre‐cultivated in a flow bioreactor for 6 weeks (group E). After 2, 4 and 6 weeks, specimens were explanted and subjected to histological and molecular biological analyses. Explanted scaffolds were invaded by fibrovascular tissue without significant foreign body reactions. Morphometric analysis demonstrated significantly increased bone formation in samples from group D (OB + BMP‐2) compared to all other groups. Samples from groups B‐E displayed significant mRNA expression of bone‐specific genes after 6 weeks. Pre‐cultivation in the flow bioreactor (group E) induced bone formation comparable with group B. In this study, differences in bone distribution between samples with BMP‐2 or osteoblasts could be observed. In conclusion, combination of osteoblasts and BMP‐2 synergistically enhanced bone formation in novel ceramic scaffolds. These results provide the basis for further experiments in orthotopic defect models with a focus on future applications in orthopaedic and reconstructive surgery.

2009年内蒙古自治区盟(市)、旗县(区)两级健康教育机构与人力资源现状调查

目的了解2009年内蒙古盟市、旗县(区)两级健康教育机构与人力资源现状。方法采用《2009年健康教育所(中心)业务工作调查表及基本情况调查表》(卫统46表)对内蒙古盟市、旗县(区)两级健康教育机构设置、人力资源、经费和活动形式进行问卷调查。结果全区12个盟市中有7个盟市级健康教育所为独立建制;104个旗县(区)均有健康教育机构,其中有20个为独立建制。盟市、旗县(区)两级分别有专职健康教育人员73人和190人,两级机构人员学历以本科(40.7%)和大专(39.5%)为主,职称构成均以中级(36.5%)和初级(39.16%)为主,医学背景(公共卫生或临床医学)人员比例仅为人员总数的32.3%。两级健康教育机构的经费主要来源于财政拨款,健康教育机构的工作形式主要有印刷小册子、折页、宣传画、举办健康知识讲座等。结论内蒙古自治区健康教育存在管理体制不顺,专业人员数量偏少、整体素质偏低,财政投入不足,活动形式过于老化与单一等突出问题,需要在医药卫生体制改革中得到解决。     

Mayo's Older Americans Normative Studies: Age- and IQ-Adjusted Norms for the Trail-Making Test,the Stroop Test,and MAE Controlled Oral Word Association Test

ABSTRACT

Although normative data sets for standardized neuropsychometric instruments often include adjustments for subject variables, there are reasons to believe that improvements in interpretive accuracy that result from such adjustments are less than optimal. In particular, years of formal education may be less closely related to test performances than is general intellectual functioning. In this second of four reanalyses of results from the Mayo Clinic's Older Americans Normative Studies (MOANS) databases, age-adjusted scores for the Trail-Making Test, the Stroop Color-Word Test, and the MAE Controlled Oral Word Associations Test were found to be more strongly associated with Mayo age-adjusted WAIS-R Full Scale IQ scores (rs = .368 to .495) than with education (rs = .174 to .367) for healthy older examinees between 56 and 99 years of age. For the TMT and the COWAT, but not the Stroop, these associations became stronger as IQ increased (cf. Dodrill, 1997 Dodrill , C. B. ( 1997 ). Myths of neuropsychology . The Clinical Neuropsychologist , 11 , 1 – 17 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 1999). Tables of age- and IQ-adjusted percentile equivalents of MOANS age-adjusted TMT, Stroop, and COWAT scores are presented for eleven age ranges and seven IQ ranges.
