Objective:To study the effect of electrical stimulation of efferent vagus nerve on the acute liver injury induced by endotoxemia in rabbits. Methods:Sixteen rabbits were randomly divided into stimulation group(Group A,n=8) and control group (Group B,n=8).They were subjected to bilateral cervical vagotomy and intravenously challenged by lipopolysaccharide (LPS) (*** 0111:B4,DIFCO,USA) at a dose of 100 μg/kg injected within 30 *** distal end of the left vagus nerve trunk was placed across bipolar electrodes connected to a stimulation module and controlled by an acquisition *** with constant voltage (10V,5Hz,5ms) were applied twice to the nerve for 10 min before and after the administration of LPS in Group *** the time 30,60,120,180,240,300 min before and after infusion of LPS respectively in each animal,blood samples were taken for late measurement of the serum Alanine aminotransferase (ALT),Aspartate aminotransferase (AST),tumor necrosis factor-α(TNF-α) and interleukin-10 (IL-10).Immediately after the experiment was finished,autopsy was performed and liver samples were taken to pathologic study. Results:Compared with Group B,the electrical stimulation of efferent vagus nerve could significantly decrease the contents of ALT,AST and TNF-α,but increase the contents of IL-10,in serum of Group *** could also alleviate inflammation of liver tissue after LPS attack. Conclusion:The results suggest that excitation of the efferent vagus nerve can inhibit the inflammation cascade in liver after LPS ***,it might have a protective effect on acute liver damage caused by endotoxemia.

Tourism development surely has social, economic and environmental impacts on tourist *** study on resorts residents' attitudes can help understand the nature of tourism development and the extent to which it may influence on tourist destinations. By now, researches on residents' perception and attitudes are plenteous in the international circle and achievements are great, yet few are found in developing countries. As a most representative cultural tourist destination, World Cultural Heritage-Xidi and Hong villages in Yi County of Anhui Province, are drawing the attention of both tourists and academic circles. This article, taking Xidi and Hong villages as examples, seeks to analyze ancient village residents' attitudes towards tourism impacts and then tries further to explore the connection between tourism development and residents' attitudes. Both qualitative and quantitative surveys are applied in the exploratory investigation into local residents' attitudes of tourism impacts. Based on abundant face-to-face interviews with the local households, tourism enterprises concerned, local government and tourists from July to August of 2002, we are able to have a better understanding of local residents' attitudes to community life, and perception of tourism impacts on society, economy and environment. By this we can promote domestic study on resorts residents' attitudes, and provide some theoretical grounds for establishing tourism development planning and perfect community participation system at tourist destinations.

Acute lung injury (ALI) is a leading complication in extensively burnedpatients, especially those with inhalation injury. It can cause hypoxia resulting in injury ofremote organs and dysfunction. p38 mitogen-activated protein kinase (p38 MARK) is a stress activatedprotein kinase in the MARK family. Most of the previous studies have demonstrated that p38 MARKsignal transduction pathway mediated All in rats with acute severe pancreatitis, sepsis ***, there is little information regarding the role of p38 MARK signal transduction pathway inALI after severe burn trauma.

In the Hellings Nordtvedt theory, we obtain some expressions of energy radiation and mass defect effect for a kind of the active galactic nuclei, which is meaningful to calculating the energy radiation in the procession of forming this kind of celestial bodies. This calculation can give some interpretation for energy source of the jet from the active galactic nuclei.

The importance of cosmological constant for the cosmological models is given. The variations of the cosmological model for parameters and were discussed respectively. Near , the cosmological model is unstable with the change of , and near , the cosmological model is unstable with the change of . So when we consider the stable cosmological model, we must consider the nonzero cosmological constant.

The effect of lateral oxidation on microstructures of the GaAs/AlAs/GaAs heterostructure was studied by x-ray specular reflectivity, nonspecular scattering and diffraction. The GaAs/Al2O3/GaAs multilayer was obtained after oxidation of the GaAs/AlAs/GaAs sample. The results show that, before oxidation, there are two 40-Å-thick intermixing layers, one located between the AlAs sublayer and the GaAs substrate, and the other between the AlAs sublayer and the upper GaAs sublayer. After oxidation, these two intermixing sublayers disappear. The AlAs was oxidized into amorphous Al2O3 totally. The surface and interface roughnesses of the sample also decrease after oxidation.

We study the dynamics of the Einstein-Maxwell-dust system and find that the system presents a critical point of a centre-centre-type structure in the phase space. By performing the numerical experiments, we find that the dynamics of the Einstein-Maxwell-dust system is unstable and its chaotic behaviour is obvious when the Hamiltonian becomes smaller.

The lateral stability for railway vehicle dynamic system with uncertainparameters and nonlinear uncertain force vector is studied by using the Lyapunov stability theory. Arobust stability condition for the considered system is derived, and the obtained stability boundsare not necessarily symmetric with respect to the origin in the parameter space. The lateralstability analysis for a railway bogie model is analyzed by using the proposed approach. Thesymmetric and asymmetric results are both given and the influence of the adjustable parameter betaon the stability bounds is also discussed. With the help of the proposed method, the robuststability analysis can provide a reference for the design of the railway vehicle systems.
