AIM： To explore the effect of he .lie Tang （decoction for medication） on serum levels of T lymphocyte subsets, NK cell activity and cytokines in chronic hepatitis B patients. METHODS： Eighty-five patients with chronic hepatitis B were divided randomly into two groups. Fifty patients in group I were treated with he .lie Tang （HIT） and 35 patients in group II were treated with combined medication. The levels of T-lymphocyte subsets （CD^3＋, CD^4＋, CD^8＋）, NK cell activity, cytokines （TNF-α, IL-8, sIL-2R） were observed before and after the treatment. Another 20 normal persons served as group 3. RESULTS： The level of CD^4＋ cells and NK cell activity were lower, whereas the level of CD^8＋ cells in patients was higher than that in normal persons （t = 2.685, 3.172, and 2.754 respectively; P〈0.01）. The levels of TNF-α, IL-8, and sIL-2R in chronic hepatitis B patients were higher than those in normal persons （t = 3.526, 3.170, and 2.876 respectively; P〈0.01）. After 6 months of treatment, ALT, AST, and TB levels in the two groups were obviously decreased （t = 3.421, 3.106, and 2.857 respectively; P〈0.01）. The level of CD^4＋ cells and NK cell activity were increased whereas the level of CD^8＋ cells decreased （t = 2.179, 2.423, and 2.677 respectively; P〈0.05） in group I. The levels of TNF-α, IL-8, and sIL- 2R in group I were decreased significantly after the treatment （t = 2.611, 2.275, and 2.480 respectively; P〈0.05） but had no significant difference in groupII after the treatment （t = 1.906, 1.833, and 2.029 respectively; P〉0.05）. The total effective rate had no significant difference between the two groups （X^2 = 2.882, P〉0.05） but the markedly effective rate was significantly different between the two groups （X^2 = 5.340, P〈0.05）. CONCLUSION： HIT is effective in treating chronic hepatitis B. HIT seems to exert its effect by improving the cellular immune function and decreasing inflammatory cytokines in chronic hepatitis B patients. The function of HIT in protecting liver fun

Design and application of single-antenna GPS/accelerometers attitude determination system

Journal of Systems Engineering and Electronics 2008年第2期19卷 220-227页

作者： he jie Huang Xianlin Wang Guofeng Center for Control Theory and Guidance Technique Harbin Inst. of Technology Harbin 150001 P. R. China The Third Research Academy China Aerospace Science &~ Industry Corporation Beijing 100072 P. R. China

In view of the problem that the current single-antenna GPS attitude determination system can only determine the body attitude when the sideslip angle is zero and the multiantenna GPS/SINS integrated navigation system is of large volume, high cost, and complex structure, this approach is presented to determine the attitude based on vector space with single-antenna GPS and accelerometers in the micro inertial measurement unit （MIMU）. It can provide real-time and accurate attitude information. Subsequently, the single-antenna GPS/SINS integrated navigation system is designed based on the combination of position, velocity, and attitude. Finally the semi- physical simulations of single-antenna GPS attitude determination system and single-antenna GPS/SINS integrated navigation system are carried out. The simulation results, based on measured data, show that the single-antenna GPS/SINS system can provide more accurate navigation information compared to the GPS/SINS system, based on the combination of position and velocity. Furthermore, the single-antenna GPS/SINS system is characteristic of lower cost and simpler structure. It provides the basis for the application of a single-antenna GPS/SINS integrated navigation system in a micro aerial vehicle （MAV）.

Solidification Behavior of Immiscible Alloys under the Effect of a Direct Current

引用

Journal of Materials Science & Technology 2014年第10期30卷 1027-1035页

作者： Hongxiang Jiang Jiuzhou Zhao jie he Institute of Metal Research Chinese Academy of Sciences

Directional solidification experiments were carried out with Al-Pb alloys under the effect of a direct current （DC）. The experimental results show that the DC causes a migration of the minority phase droplets （MPDs） from the middle part to the surface region of the sample, Samples with either a finely dispersed microstructure or a shell/ core structure were obtained by solidifying the alloy under the effect of the properly selected DC densities, A model was developed to describe the microstructure evolution in an immiscible alloy directionaliy solidified under the effect of the DC. The microstructure formation in the AI-Pb alloys was calculated. The numerical results are in favorable agreement with the experimental ones. They demonstrate that the DC affects the microstructure formation mainly through changing the spatial motions of the MPDs and the temperature field of the melt in front of the solid/liquid interface. The formation mechanisms of the finely dispersed microstructure as well as the shell/core structure were sufficiently clarified.

Cell competition is an adaptive surveillance mechanism to ensure the robustness of developmental outputs,maintain tissue integrity,and regulate tumor progression in multicellular organisms,which is highly conserved from invertebrates to vertebrates[1].At the cellular level,cell competition represents a non-cell-autonomous process in that cells can sense the fitness of their neighbors through cellular interactions,thereby eliminating low-fitness cells and expanding high-fitness counterparts,however,cells develop normally in homogenous populations.

Industrialization, Environment and health:the Impacts of Industrial SO_2 Emission on Public health in China

引用

Chinese Journal of Population,Resources and Environment 2008年第1期6卷 14-24页

作者： he jie Département d＇Economique and GREDI Faculté d＇administration Université de Sherbrooke 2500 boulevard de I＇Univesité Sher brooke QC J1K2R1 Canada

In this paper, we construct a model in which the impact of pollution on health is exerted through both direct and indirect channels. The indirect channel is captured by a production func-tion in which the principal health-improving factor, income growth, can be realized only in the cost of pollution increase. This model is then tested by the aggregated chronicle disease data in over 78 Chinese counties. Our results show, after attaining the threshold of 8 μg/m2, continuous increase in industrial SO2 emission density will lead the ratio of population suffering chronicle diseases, among which respiratory diseases occupy a significant proportion, to rise. However, owing to technological progress in pollution control activities, the needed SO2 emission to produce one unit of GDP diminishes with time. Therefore, the negative effect from pollution augmentation on public health seems to be recompensed more and more by the positive effect of economic growth.

A Model for Evaluation of Grain Sizes of Aluminum Alloys with Grain Refinement Additions

引用

Journal of Materials Science & Technology 2007年第5期23卷 619-622页

作者： Zhongwei CheN Zhi he Wanqi jie State Key Laboratory of Solidification Processing Northwestern Polytechnical University Xi＇an 710072 China

Based on the assumption that the nucleation substrates are activated by constitutional undercooling generated by an adjacent grain growth and solute distribution during the initial solidification, a model for calculation of the grain size of aluminum alloys with the grain refinement is developed, where the nucleation is dominated by two parameters, i.e. growth restriction factor Q and the undercooling parameter P. The growth restriction factor Q is proportional to the initial rate of constitutional undercooling development and can be used directly as a criterion of the grain refinement in the alloys with strong potential nucleation particles. The undercooling parameter P can be regarded as the maximum of constitutional undercooling △Tc. For weak potential nucleation particles, the use of RGS would be more accurate. The experimental data of the grain refinement of pure aluminum and AlSi7 alloys are coincident predicted results with the model.
