In the chiral SU(3) quark model, we use the coupling between quarks and nonet scalar meson fields and nonet pseudo-scalar meson fields to describe the medium and long range interactions, and use one gluon exchange to describe the short range interaction. In the extended chiral SU(3) quark model, besides the nonet pseudo-scalar meson fields and the nonet scalar meson fields, the coupling between vector meson fields and quarks is also considered, the short range interaction can be dominately described by vector meson exchange. We investigate the nucleon-hyperon interaction in the extended chiral SU(3) quark model and study the S-wave phase shifts of N-Λ and N-Σ systems. Comparing to the results in chiral SU(3) quark model, we find that the short-range interaction could be described either by the one-gluon exchange or vector meson exchange.

在手征SU(3)夸克模型中，用夸克与标量介子九重态和赝标介子九重态场的耦合来描述中长程相互作用，单胶子交换来描述短程相互作用，推广的手征SU(3)夸克模型是在原来手征SU(3)夸克模型的基础上进一步引入了夸克和矢量介子九重态场的耦合，主要由矢量介子交换来描述短程相互作用，在推广手征SU(3)夸克模型下研究了核子－超子相互作用过程，计算了N-Λ和N-Σ相互作用的S波散射相移，通过和手征SU(3)夸克模型的结果比较，发现N-Λ和N-Σ系统的短程相互作用既可以由单胶子交换来描述，也可以由矢量介子交换来描述。

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。

Results Analysis of the expression of proteins of JAK2 in leukemic blasts, there was no detectable constitutive expression of phosphorylated JAK2 in all the AML samples analyzed; Furthermore, we could detect a constitutive activation of STAT 3 by immunoprecipitation of the targeted protein in primary leukemic blasts from 3 of 11 AML patients without any cytokine treatment; Pretreatment clinical characteristics, and treatment regimens did not differ significantly between patients with and without constitutive STAT3 activity, there was not significant relation between the constitutive activation of STAT3 and the FAB subvariety and chromosome karyotype; However, the 3 patients with constitutive STAT3 activity seemed to have adverse treatment outcome, one did not show remission, the other two patients relapsed shortly after remission; Consistent with the above-mentioned result, leukemic blasts from the 3 samples with constitutive expression of STAT3 showed higher percentage of spontaneous apoptosis and S-phase cells.

The relationships between germination of the teliospores of Tilletia conroversa Kühn and soil moisture were studied and it was found that the teliospores of TCK could germinate when the soil mass moisture content reached between 1%-28%(relative moisture capacity 3.75%-100%). The suitable moisture for teliospore germination was between 10%-25% of mass moisture capacity or 17.85%-89.3% of relative moisture capacity. The optimal soil relative moisture capacity was between 65%-75%. There was no difference among most TCK isolates tested at the same suitable soil moisture.

In order to direct the construction of plant germplasms by elucidating the relatives among plants at the level of gene, CYP86MF gene analogues from 11 species of 6 genera in Cuciferae were respectively obtained by PCR strategy using gene specific primers designed from conserved regions of CYP86MF gene reported. Sequence comparisonindicated that the similarities among the genes at nucleotide level were over 80%, and the similarities at amino acid level remained above 70%. The differences between the genes at nucleotide and amino acid level between species were 1.0%~ 5.7% and 2.6%~ 7.3% respectively, while those between genera 5.6%~ 22.5% and 7.3%~ 31.2%, respectively. Phylogenetic analysis showed that Brassica was closely related to Raphanus, followed by Rorippa Scop, Arabidopsis Heynh, Capsella Medic orderly, most distantly related to Orychophrogmus.
