Methods Immunohistochemistry was used to detect the expression of OPN and CD44 in the LECs of anterior subcapsular cataracts(22 cases)、nuclear cataracts(17 cases)、cortical cataracts(14 cases) and normal lenses(11 cases),and positive cells were counted.

方法采用免疫组织化学法检测22例前囊下白内障1、7例核性白内障、14例皮质性白内障患者和11例正常晶状体上皮细胞中OPN和CD44的表达，并进行阳性细胞计数和各组间比较。

Methods The MMP-3, OPN, and TIMP-1 expressions in LECs of anterior subcapsular cataract (31 cases), nuclear cataract (28 cases) and normal lens (12 cases) were detected by immunohistochemistry, respectively.

采用免疫组织化学方法测定MMP-3，OPN和TIMP-1在31例前囊下性白内障，28例核性白内障和12例正常晶状体上皮细胞中的表达。

Stamens usually 6 in 2 whorls, rarely 3 or 1, inserted on perianth, often unequal or dissimilar; filaments slender, free; anthers 2-loculed, introrse, dehiscing by longitudinal slits or rarely by pores; pollen grains 2- or 3-nucleate, colpi 1 or 2(or 3), distal or subequatorial.

雄蕊通常6，2轮，很少3或者1，着生在花被上，通常不等长或者不同；花丝纤细，离生；花药2室，内向，纵向开裂或少数孔裂；花粉粒2-3核， 1或者2(或者3)沟，远轴或者近赤道面。

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.

在实验研究基础上，本研究进一步运用免疫沉淀和Western Blot印迹方法，检测AML患者原代细胞JAK2和STAT3活化情况，并分析了STAT3活化与AML患者预后有关指标改变的关系。结果我们的初步研究发现，11例AML患者中，有3例呈现STAT3组成型活化（STAT3阳性，下同），无一例呈JAK2组成型活化。上述3例STAT3组成型活化与FAB分型和染色体核型改变未见明显相关性；在此3例患者中，1例未取得缓解，另外2例虽然取得短暂缓解，但均在二个月内复发。上述3例STAT3阳性AML患者S期白血病细胞百分率数值较组高，而凋亡率数值较低。

A general trend in the research of symbiosis in ciliates is further exploration of the influence of the symbiont on the gene structure and gene expression of the host. The expected results will contribute to a better understanding of the regulatory mechanisms controlling the interaction,the exchange of substances between the host and symbiont at a molecular level, and the pattern of life processes sur rounding the relationship between cellular structures and functions in eukaryocytes.

作者推测，探索共生体对宿主基因结构及其表达产物的影响可能是对纤毛虫中共生作用研究的主要趋势，这对于深入了解真核细胞中宿主-共生体双方的相互作用、物质交流在分子水平上的调控机理、细胞结构与功能的关系等细胞生命活动规律是有意义的。
