红细胞作为吗啡载体延长吗啡镇痛时效的研究

探讨用高渗法制备红细胞包蔽吗啡溶液(RBG—M)的可行性。对RBC—M制备过程中红细胞(RBC)的体积和形态的变化、RBG—M溶液内外的吗啡(M)浓度及含量的变化以及择期上腹部手术患应用RBC—M溶液术后镇痛的时效和吗啡的血药浓度进行了研究。研究发现：(1)用高渗法制备红细胞包蔽吗啡溶液是可行的。(2)RBG—M溶液与单纯M溶液相比其术后镇痛作用显延长；其药代动力学指标消除半衰期(T1／2)延长3倍多。曲线下面积(AUC0→∞)增加约11倍。而清除率(CL)明显减小约9倍。(3)用RBGM溶液行术后镇痛的患其时效明显优于单纯用吗啡的患。     

Dynamical framework with blocking topography coordinates for atmospheric GCM and its validation

The dynamical framework with Blocking Topography Coordinates (hereafter, BTC), which is suited to handle the steep topography for the atmospheric general circulation models, is presented in this paper, together with its validation results. The integral properties of both the differential and finite-difference equations for the BTC dynamical core are: gross mass conservation, quadratic conservation for advection terms, Coriolis force does not change the kinetic energy, conservation of total available energy. The improved nonlinear iteration scheme is utilized for the time-integration. The energy conservation for BTC dynamical core is validated by using the integration results from 9-layer and 21-layer version respectively. Comparison results show that, the changes of the kinetic energy and total available potential energy during the integration are quite close for both the BTC dynamical framework and the dynamical framework of IAP 9-level and IAP 21-level AGCM, and this may suggest that the BTC dynamical core can be used for long-term integration with good computational stability. Furthermore, the BTC dynamical core has the advantage over the terrain following (sigma) coordinates in its better representation of the influence of the large-scale topography on the atmospheric general circulation. Finally, the correctness and reasonableness of the BTC dynamical core has been further proved by the numerical simulation of the topography influence on the quasi-stationary planetary wave with 21-layer version of BTC dynamical framework.
