“气增而久,夭之由也”临床运用探析

《黄帝内经》言:"气增而久,夭之由也。"是指长期服某一种作用的药物或食物,机体长期处于偏亢状态,是疾病之源。该理论临床重视不足,导致诸多不良后果,甚至形成临床指导思想的偏差。重新审视,可救偏补弊。临床扶正治疗中,要适度而不可滥用补药;临证祛邪用药过程中,要谨守中病则止原则,不可过度治疗徒增他病;生活指导方面,要遵循患者自我疗能需要,适合则用,不必固守成规。临床医家应熟悉该理论,并推广指导临床,逐渐改善现存不良现象。

目前政府间财政转移支付制度存在的主要问题

1.中央对地方《过渡期转移支付办法》有待进一步改进。中央对地方的《过渡期转移支付办法》在三年的运行中虽然进行过补充修改,但在结构及其功能方面还存在一些问题。反映较多的是:财政转移支付规模不规范,表现为随意性较大,力度较小;在测算级次上,只是以省为单位进行测算,没有考虑不同级次政府支出标准的差异,这将对测算的准确性有所影响,容易产生不合理的分配结果。此外,在因素的选择上对一些地区的特殊因素考虑较少,有些因素的选择和确定还需要进一步的数据支持等。

食肉植物

世界上约有500种食肉植物。 食肉植物多生长在泥塘沼泽及附近的潮湿土地或浸水的土地上。这些地方的植物往往缺氮,捕食动物可以补充氮的不足。 食肉植物跟别的植物一样,靠光合作用制造养料。实际上食肉植物不吃动物也能生存,不过补充了肉食生长得更加茁壮茂盛。 食肉植物用非常巧妙的办法,设各种陷阱诱捕动物,主要是昆虫。 茅膏菜 叶上满布红色或鲜橙色的毛。

Void fill and support techniques to stabilize drift excavated through a transition zone mined by a TBM at the Stillwater mine

Stillwater Mining Company is the only U.S. producer of platinum group metals （PGMs） and the largest producer outside of South Afiica and Russia. The company controls a considerable portion of the J-M reef and is currently developing the ＂Blitz Project,＂ which will provide a main haulage level, ore pass systems, backfill plants, and fiow-through ventilation to increase production and ensure sustainable extraction of this critical strategic mineral. While driving two sub-parallel footwall laterals 8125 m in length, one of the development drifts experienced a massive fall in a geologically disturbed area created by a mafic dike intrusion. Combinations of a void fill material （Tekseal）, polyurethane injection, fore poling coupled with steel arches, and supplemental bolting allow safe and efficient advance through this geologically dis- turbed zone. This paper presents the details of this project.

Considering Process Nonlinearity in Dual-Point Composition Control of a High-Purity Ideal Heat Integrated Distillation Column

Dual-point composition control for a high-purity ideal heat integrated distillation column (HIDiC) is addressed in this work. Three measures are suggested and combined for overcoming process inherent nonlinearities:(1) variable scaling; (2) multi-model representation of process dynamics and (3) feedforward compensation. These strategies can offer the developed control systems with several distinct advantages: (1) capability of dealing with severe disturbances; (2) tight tuning of controller parameters and (3) high robustness with respect to variation of operating conditions. Simulation results demonstrate the effectiveness of the proposed methodology.

Method of closed loop springback compensation for incremental sheet forming process

The closed loop control model was built up for compensating the springback and enhancing the work piece precision.A coupled closed loop algorithm and a finite element method were developed to simulate and correct the springback of incremental sheet forming.A three-dimensional finite element model was established for simulation of springback in incremental sheet forming process.The closed loop algorithm of trajectory profile for the incremental sheet forming based on the wavelet transform combined with fast Fourier transform was constructed.The profile of processing tool path of shallow dishing with spherical surface was designed on the basis of the profile correction algorithm.The result shows that the algorithm can predict an ideal profile of processing track,and the springback error of incremental sheet forming is eliminated effectively.It has good convergence efficiency,and can improve the workpiece dimensional accuracy greatly.

Radiofrequency ablation of atrial tachycardia in patients with repaired atrial septal defect

Objective:To evaluate the electrophysiological characteristics and radiofrequency catheter ablation of atrial tachycardia (AT) in patients with repaired atrial septal defects(ASD). Methods: In 76 consecutive patients with AT who underwent the electrophysiological study and radiofrequency catheter ablation (RFCA). 4 patients (one male and three female aged 35. 5±11. 5 years) had AT-related myocardial scar or incision. Earliest activation combined with entrainment mapping was adopted to determine a critical isthmus. Results: Re-entry related to the lateral atriotomy scar was inducible in 3 of 4 patients. With en-trainment mapping, the PPI-TCL difference was <30 ms when pacing at the inferior margins of the right lateral atriotomy scar. Among them, 2 patients had successful linear ablation between scar area to inferior vena cava, and 1 patient between scar areas to tricuspid annulus. Re-entry involving an ASD patch was demonstrated in 1 of 4 patients. PPI-TCL differences <30 ms were found when entraining tachycardia at sites near the septal patch. But linear ablation failed in terminating AT. There was no complication during procedure. No recurrence of incision-related AT was found during follow-up except for the failed patient. Conclusion: Under conventional electrophysiological mapping, adopting linear ablation from scar area to anatomic barrier, successful ablation also can be obtained in patients with IRAT related to myocardial scar or incision.

The Extent of Land Use Impact on Water Regime in the Vseminka Catchment

The paper deals with the impact of land use changes on water regime. An assessment was carried out in order to determine the extent to which the main components of the water balance on the experimental catchment Vseminka have been influenced by land use changes （region Vsetinske Hills, the Czech Republic）. For this reason, the water balance model WBCM-5 was implemented for the period of 30 years in a daily step, with particular focus on the simulation of the components of direct runoff and of subsurface water recharge. In the selected years of the period 1980-2009, major changes were made in land use and significant fluctuation of rainfall-runoff regimes were observed （e.g. dry year 1992, flood year 1997 and normal year 2009）. After WBCM-5 parameter calibration it was observed that some water balance components can change in relation to substantial land use changes, even up to dozens of percent in a balance-consideration, i.e. in daily, monthly and yearly or decadal values, specifically as far as the components of interception and also of direct runoff and of subsurface water recharge are concerned. However, a different situation appeared during the investigation of significant short-term rainfall-runoff processes. There were about seven real flood events during the same period on the same catchment which were analysed using the KINFIL-2 model （time step 0.5 hr）. Land use change, positive or negative scenarios, were also analysed during this period. As opposed to long-term water balance analyses, only a 10% difference in the hydrograph peak and volume was observed. In summary, the authors have shown that it is always important to distinguish a possible land use change impact on either long-term balance or short-term runoff. Otherwise, as often found in over simplified commentaries on flood events in the mass media, the actual impact of land use changes on water regime may be misunderstood.

Substitution or Complementarity Between ＂Soft＂ Information and ＂Hard＂ Information： Why and Which Effect on Bank Profitability？

The Basel II committee sets their customers. This new up directives encouraging banks to use internal scores in order to assess the risk of form of information competes with the existing ones. Small and medium-sized enterprises （SMEs） are most concerned by these new stakes, due to the lack of transparency. The aim of this paper is to understand the determinants of the choice between substitution and complementarity between the two types of information： ＂soft＂ and ＂hard＂, to test a potential effect of this choice on the banking performance and to describe which variables are involved in the decision-making process. The originality of this work is to try to quantify the information costs and to use it as a variable which is affecting the adopted choice.

Effects of Spatial Information of Soil Physical Properties on Hydrological Modeling Based on a Distributed Hydrological Model

The spatial distribution of soil physical properties is essential for modeling and understanding hydrological processes. In this study, the different spatial information (the conventional soil types map-based spatial information (STMB) versus refined spatial information map (RSIM)) of soil physical properties, including field capacity, soil porosity and saturated hydraulic conductivity are used respectively as input data for Water Flow Model for Lake Catchment (WATLAC) to determine their effectiveness in simulating hydrological processes and to expound the effects on model performance in terms of estimating groundwater recharge, soil evaporation, runoff generation as well as partitioning of surface and subsurface water flow. The results show that: 1) the simulated stream flow hydrographs based on the STMB and RSIM soil data reproduce the observed hydrographs well. There is no significant increase in model accuracy as more precise soil physical properties information being used, but WATLAC model using the RSIM soil data could predict more runoff volume and reduce the relative runoff depth errors; 2) the groundwater recharges have a consistent trend for both cases, while the STMB soil data tend to produce higher groundwater recharges than the RSIM soil data. In addition, the spatial distribution of annual groundwater recharge is significantly affected by the spatial distribution of soil physical properties; 3) the soil evaporation simulated using the STMB and RSIM soil data are similar to each other, and the spatial distribution patterns are also insensitive to the spatial information of soil physical properties; and 4) although the different spatial information of soil physical properties does not cause apparent difference in overall stream flow, the partitioning of surface and subsurface water flow is distinct. The implications of this study are that the refined spatial information of soil physical properties does not necessarily contribute to a more accurate prediction of stream flow, and the selection of appropriate soil physical property data needs to consider the scale of watersheds and the level of accuracy required.

The Synergistic Effect of HT and Complement Regulatory Proteins in Resisting the Immunological Rejection of Heterogenic Transplantation

Objective：To establish the polytransgenic mice expressing the human HT and complement regulatory proteins （CRPs） and discuss their ability to resist the hyperacute rejection （HAR） and delayed xenograft rejection （DXR） of heterogenic transplantation. Methods ：Transgenic mice were produced by microinjection to construct gene for human HT, delay acceleration factor （DAF） and/or CD59 into the male pronucleus of zygote. PCR and Southern blot were used to screen the positive trarisgenic mice. Flow cytometry （FCM） was used to detect the expression of HT, ct-Gal and DAF or CD59 on the PBMCs of transgenic mice. The survival time and function of the heart of transgenic mice were determined by a modified Langendorff cardiac perfusion apparatus： The change of proteinosis on IgM,IgG, C3c and C9 from different cardiac vascular iendothelial cells of transgenic mice were detected by immunohistochemistry. Results：HT, DAF or CD59 were highly expressed on the positive transgenic mice by FCM. The deposition of IgM,IgG,C3c or C9 in the cardiac vascular endothelial cells of the positive transgenic mice were de- creased. The survival time and function of the heart of the co-transgenic mice with AB serum perfusion were significantly longer and higher than that of the single HT positive transgenic mice（P 〈0.05）. Conclusion ：The mice co-expressing HT/DAF or HT/CD59 could resist the HAR,which was better than those expressing HT alone. It is feasible to use HT and CRPs co-transgenic methods to resist the HAR and DXR.

Intelligent decoupling PID control for the forced-circulation evaporation system

The control objective of the forced-circulation evaporation process of alumina production is not only to avoid large fluctuations of the level, but also to ensure the product density to track its setpoint quickly. Due to the existence of strong coupling between the level loop and the product density loop, and high nonlinearities in the process, the conventional control strategy cannot achieve satisfactory control performance, and thus the production demand cannot be met. In this paper, an intelligent decoupling PID controller including conventional PID controllers, a decoupling compensator and a neural feedforward compensator is proposed. The parameters of such controller are determined by generalized predictive control law. Real-time experiment results show that the proposed method can decouple the loops effectively and thus improve the evaporation efficiency.
