Medicinal synthetic Aluminum-magnesium silicate (MSAMS), which has inhibited Human immune deficiency virus (HIV), in vitro, was used for trial-treatment of HIV/AIDS patients. Their plasma were tested for viral loads (VL): before and repeatedly during the treatment. The regimen was: MSAMS (50 mg/kg), MSAMS-stabilized Ampicillin trihydrate (7.5 mg/kg) and immunace extra protection?. After 4 weeks, it was reduced to 50 mg/kg (MSAMS) and the immune stimulant. When VL decreased bellow 50/ml, the treatment continued, 4 weeks before stopping. Mean-VL of four patients increased (P = 0.006) from 498.50 ± 33.37 to 1,072.50 ± 184.55, after 3.75±2.06 weeks and decreased (P = 0.040) to 407.33 ± 297.27 (18.29%) when the treatment-duration increased to 6.67 ± 2.31 weeks. Prolonging the duration to 12.00 ± 2.83 weeks led to 98.68% decrease of mean-VL of four other patients, from 24,250.00 ± 15,939.34 to 321.00 ± 229.38(P = 0.045). Two HIV positive persons treated for 4 weeks after their VL reduced bellow 50/ml have remained healthy, 10 and 16 months respectively, without routine antiretroviral medication.

AIM: To study the benef icial effects of triterpene α,β-amyrin and the underlying mechanisms in an experimental pancreatitis model. METHoDS: Acute pancreatitis was induced in five groups of rats (n = 8) by L-arginine (2 × 2.5 g/kg, intraperitoneal, 1 h apart) and 1 h later, they received a single oral dose of α,β-amyrin (10, 30 and 100 mg/kg),methylprednisolone (30 mg/kg) and vehicle (3% Tween 80). A saline (0.9% NaCl) treated group served as a normal control. Efficacy was assessed at 24 h by determination of serum levels of amylase, lipase and proinflammatory cytokines [tumor necrosis factor (TNF)-α and interleukin (IL)-6], pancreatic myeloperoxidase (MPo) activity, lipid peroxidation [thiobarbituric acid reactive substances (TBARS)], nitrate/nitrite levels, and the wet weight/body weight ratio. Tissue histology and the immunoreactivity for TNF-α and inducible nitric oxide synthetase (iNoS) were performed. RESULTS: α,β-amyrin and methylprednisolone treatments significantly (P ody weight ratio, and decreased the serum levels of amylase and lipase, and TNF-α and IL-6, as compared to the vehicle control. Also, pancreatic levels of MPo activity, TBARS, and nitrate/nitrite were signifi cantly lower. Histological f indings and TNF-α and iNoS immunostaining further confirmed the amelioration of pancreatic injury by α,β-amyrin. CoNCLUSIoN: α,β-amyrin has the potential to combat acute pancreatitis by acting as an anti-in? ammatory and antioxidant agent.

In order to optimise land use systems, to prevent erosion-induced degradation and to restore the degradedred soils in subtropical China, five cropping systems and four agroforestry systems were conducted in red soilswith a slope of 7° from 1993 to 1995. The results showed that erosion risk period occurred from April to June,and the annual runoff and the losses of soil and nutrients with sediment were alarming for two conventionalfarming systems, whereas they were negligible for the farming systems with ridge tillage. Enrichment ratiosof the lost soils from erosion were more than 1 .20 for all nutrients with much higher values for hydrolysable Nand organic matter. Compared with the control, the alley cropping systems also distinctly decreased runoffby 30% or 50%. However, the coverage of soil surface varied with alley cropping systems for the competitionof nutrients and soil water, which made a profound difference in runoff. The cropping systems of sweet potatointercropped with soybean, the alley cropping systems and the measures of mulching and ridge tillage werethe alternatives for red soil reclamation so as to prevent erosion-induced degradation.

In this paper, the techniques to manage and control the flow over airfoils by using the external unsteady excitations are investigated. The mechanisms of these excitation effects are also explored. The principal goal of this study is to gain a better understanding and to find the possible ways for enhancing the aerodynamic efficients. The experimental investigations are carried out in two low-speed wind tunnels. The test models are two dimensional airfoils with different section geometries. Four means of excitations have been used in these experiments. (1) The pitch oscillation of the airfoil high-angle-of-attack situation. (2) The moving surface effects of the airfoil with a leading edge rotating cylinder. (3) oscillating leading edge flaperon. (4) Small oscillating spoiler located near the leading edge of the airfoil. The lift, drag and pitch moment coefficients are measured in these experiments. But, we will put the emphasis only on the 'dynamic amplifying effects' on aerodynamic lift in this paper. Results obtained indicate that the beneficial aerodynamic effects of section lift increase can be obtained at the high angle of attack near stall regime, as long as the frequency and amplitute of the excitation are appropriately selected.

In this paper, Laplace transform method is used to solve the problem of wave scattering from the rough surface. The rough surface is described by y=ζ (x, z) . First, we make Laplace transform to y variable, then do the Fourier transform to x and z variables. In the k space, we can obtain the solution of the problem of wave scattering by simple algebraic operation. Finally, the Laplace inverse transform is performed by complex variable method and Fourier inverse transform by stationary phase method.

目的研究碳纤维钢骨—钢管混凝土柱在双向偏心荷载作用下的力学性能,为实体试验提供理论依据.方法利用有限元软件ABAQUS,通过选取单元类别、设定相互作用等一系列建模过程,建立了5种不同参数下的13个试件模型,通过软件分析得到双向偏心压弯试件的荷载-挠度曲线.结果随着偏心距的增加,试件的承载力与抗弯刚度均逐渐下降;随着碳纤维层数的增加,试件的承载力显著上升,但延性迅速下降;随着长细比的增加,试件的破坏形式由内部材料破坏逐渐变成整体失稳破坏,抗弯刚度与极限承载力均有所下降,但延性有所增加;随着缀板间距的减小,受约束混凝土的强度增大,试件的承载力也越高;随着加载角度的变化,试件的力学性能几乎保持不变.结论碳纤维钢骨-钢管混凝土柱在双向偏心荷载作用下具有良好的承载力与刚度,延性系数也符合抗震要求.

The growth and ordering of {5,10,15,20-tetrakis（4-bromophenyl）porphyrinato}nickel（II）（NiTBrPP） molecules on the Au（111） surface have been investigated using scanning tunnelling microscopy, X-ray absorption, core-level photoemission, and microbeam low-energy electron diffraction. When deposited onto the substrate at room temperature, the NiTBrPP forms a well-ordered close-packed molecular layer in which the molecules have a flat orientation with the porphyrin macrocycle plane lying parallel to the substrate. Annealing of the NiTBrPP layer on the Au（111） surface at 525 K leads to dissociation of bromine from the porphyrin followed by the formation of covalent bonds between the phenyl substituents of the porphyrin. This results in the formation of continuous covalently bonded porphyrin networks, which are stable up to 800 K and can be recovered after exposure to ambient conditions. By controlling the experimental conditions, a robust, extended porphyrin network can be prepared on the Au（111） surface that has many potential applications such as protective coatings, in sensing or as a host structure for molecules and clusters.
