浙江 江西两省矿业权流转情况与思考

矿产资源是国家的重要资源,探矿权、采矿权为国家所有。“两权”的流转应体现公平、竞争的原则,防止国有资产流失。

明清实学思潮的理论创新与本体论特点

从明中晚期到鸦片战争前后的本体论学说主要表现为对宋明道学本体论的批评和对新的本体论形态的探求。犹如西方哲学史中本体论的现当代转化一样 ,思想家们在扬弃“道”、“理”、“心”等僵化的本体过程中 ,力图对相当于海德格尔的“此在”的“主体”进行界定。他们不把本体当作圆满的先验预设 ,认为道德学首先应该使自身成为知识学。这种本体论思想的出现标志着中国本体思想的近代转化

Diagnosis of Congenital Cardiac Right-to-left Shunts with 99mTc-macroaggregated Albumin

Diagnosing right-to-left congenital cardiac shunts can be difficult. Cardiac catheterization and angiocardiography represent the traditional gold standard for diagnosis, but they are invasive. Nuclear scintigraphy using 99mTc-macroaggregated albumin (MAA) has been employed in humans as an alternate method of diagnosis. This study reviews eight dogs presented for evaluation of a suspect right-to-left cardiac shunt that were examined using 99mTc-MAA. In all, 2-4 mCi (74-148 MBq) of reduced particle 99mTc-MAA were injected IV in a cephalic vein and static images of the whole body, including right and left lateral, dorsal, and ventral views, were acquired for 60 s and stored into a 256 x 256 x 16 matrix. Shunt fractions were calculated. One dog with radiopharmaceutical distribution limited to the lungs did not have a shunt. Seven dogs had distribution of the radiopharmaceutical outside the pulmonary capillary bed, indicating bypassing of the pulmonary capillary circulation due to a right-to-left shunt. Four dogs had 99mTc-MAA within the brain. Three dogs that did not have brain uptake, but instead had a sharp cutoff of radioactivity at the level of the front limbs and neck, were diagnosed with reverse patent ductus arteriosus (PDA). The asymmetric distribution of the radiopharmaceutical is due to the location of the shunt, distal to the brachiocephalic trunk and left subclavian artery. Shunt fractions of dogs with extrapulmonary radioactivity ranged from 40% to 59%. Nuclear scintigraphy with 99mTc-MAA is a quick alternative method of diagnosing right-to-left cardiac shunts that permits quantification of shunt fraction. Distinguishing between reverse PDA and other right-to-left shunts may be possible based on the radiopharmaceutical distribution.     

西尼罗热病毒RT-PCR检测方法的建立

参考Genebank发表的西尼罗热病毒(West Nile virus，WNV)E糖蛋白基因序列，自行设计合成一对引物，对WNV进行RT—PCR扩增，产物经琼脂糖电泳分析，呈现一条约400bp的条带，将其克隆入pMD18-T—Vector载体中，并进行序列测定，与已发表的WNV基因比较发现，核苷酸的同源性为99．7％，证实为WNV的E基因，通过对样品多次检测，都能扩增出一条约400bp的条带，表明该方法比较稳定。     

孔子的素质教育思想及其现实意义

孔子的教育思想是中华民族传统教育思想体系中的宝贵遗产。其教育思想与当前素质教育有很多相通之处，所以对孔子的教育思想进行解读将对我们教育实践的指导和教育理论水平的提高将大有裨益。以《论语》中孔子的言论为原材料，以他对老师和学生的要求以及如何处理师生关系这三方面为切入点浅析孔子的教育思想对现代素质教育的启示与影响。
