The Cl^- homeostasis was known as the major mechanism of soybean to achieve NaCl tolerance, but studies on the role of chloride channel under abiotic stress were relatively few. We cloned a putative CLC-type chloride channel gene GmCLCnt from soybean via RACE and it was predicted to encode a protein of 783 amino acids with 9 possible transmembrane domains and 2 tandem CBS domains. Real-time RT-PCR analysis showed that the GmCLCnt gene was expressed in all tissues of soybean but enriched in leaves and its expression was induced by NaCl, polyethylene glycol （PEG）, coldness and ABA treatments. The Arabidopsis seedlings overexpressing GmCLCnt were more tolerant to higher concentration of NaCl than those of wild type. The results suggested that the GmCLCnt may be a CLC-type chloride channel and play an important role in salt tolerance.

Based on the low energy QCD Lagrangian theory and the crossing symmetry relation, strange meson photoproduction and its associated radiative capture on the proton are investigated in the [SUSF（6） × O（3）]sym . × SUc（3） quark mode/of baryon structure with only one same input parameter, the only strong coupling constant aM. Calculations for the cross sections, p-polarization of γ ＋ P → K^＋＋ A reaction and the branching ratios for K^- radiative capture of K^- ＋ p →　γ ＋ Y with Y = A, ∑^0 are performed. Good agreements to data are obtained and the results show that, compared to traditional phenomenological models, the low energy QCD Lagrangian theory provides a successful, unifled description of the strange meson photo-production and its associated radiative capture.

According to extensive study of the Dyson-Schwinger equations for a fully dressed quark propagator in the ＂rainbow＂ approximation with an effective gluon propagator, a parametrized fully dressed confining quark propagator is suggested in this paper. The parametrized quark propagator describes a confined quark propagation in hadron, and is analytic everywhere in complex p^2-plane and has no Lehmann representation. The vector and scalar self-energy functions [1 - Af（p^2）] and [Bf（p^2） - mf], dynamlcally running effective mass of quark Mf（p^2） and the structure of non-local quark vacuum condensates as well as local quark vacuum condensates are predicted by use of the parametrized quark propagator. The results axe compatible with other theoretical calculations,

陈式太极拳练习者在练习中期或后期出现膝关节疼痛的现象不容忽视,本研究选取12名陈式太极拳练习者,其中6名为膝关节疼痛的练习者,6名为健康的练习者,采用Vicon三维运动捕捉系统记录12名练习者“懒扎衣”动作的动力学和运动学数据,比较两组练习者在各阶段的动作特征,为提高练习者技术动作的准确性与规范性及规避运动损伤提供参考。结果显示:(1)与对照组膝关节角度变化相比,疼痛组支撑腿在P1~P3阶段表现为膝关节内收(P<0.05);支撑腿在P1、P2阶段外旋更小(P<0.05);迈步腿在P1~P3阶段外旋更小(P<0.01)。(2)与对照组相比,疼痛组在P1~P3阶段表现为脊柱的屈曲(P<0.05)。(3)与对照组相比,疼痛组的支撑腿在P1、P2两个阶段和迈步腿的P2、P3阶段屈曲力矩更小(P<0.05);支撑腿在P1~P3阶段与迈步腿的P2、P3阶段外展力矩更小(P<0.05);支撑腿在P1阶段表现出比对照组外旋力矩更小(P<0.05)。结论:1.疼痛组支撑腿的膝关节角度持续处于内收状态,整个运动过程中未观察到明显变化,这将使膝关节处于不稳定状态,增加了关节周围软组织和结构的负担,从而引发膝关节损伤。2.疼痛组更小的外旋角度使得膝关节的松弛性较低且需要承受屈曲与内旋的双重负荷,进一步增加了膝关节损伤的潜在风险。3.疼痛组不能较好的利用躯干的伸展来减轻身体重心下降时施加在下肢的负荷,而身体在整个运动过程中的前屈将会使得其膝关节负荷增加,从而造成损伤。4.疼痛组在运动过程中承受膝内收力矩的做功,增加了膝关节内侧室的负荷,使损伤风险增加。

Based on the eikonalized Glauber representation of hadron-hadron scattering, we study the diffractive processes of ^-pp and pp elastic scattering at high energies. From our theoretical calculations and fits to the corresponding experimental data at high energies and all available momentum transfer, we find that the Pomeron exchange contributions play a significant role in description of differential cross section dσ/dt in the whole experimental domain. The Pomeron exchange contributions are related to multi-gluon exchanges in QCD, which are color singlet bound state of Reggeized gluons, such as tensor glueball and Odderon. Accordingly, we may claim that the ^-pp and pp diffractive processes at high energies s and moderate momentum transfer t would be a good tool to verify the existence of the color singlet multigluon bound states and to test QCD since QCD theory does predict the existence of these states. Therefore, we believe that the experimental measurement should be done for these diffractive processes.

Based on the fully dressed confining quark propagator, the pion decay constant fπ, local quark vacuum condensate, and the masses of light quarks and in-medlum Goldstone bosons are investigated. The pion decay constant fπ is predicted and compared with its value of experimental measurement. A great agreement is obtained. With the predicted fπ and values of Goldstone boson masses measured by experiments in free configuration the current masses of light quarks and the masses of in-medium Goldstone bosons are obtained.
