侵袭素

An h-VRSA strain isolated from clinical specimen was induced to increase its resistance to vancomycin in vitro. The coagulase, lecithinase, hemolysin of this resistant strain and its pathogenicity to laboratory animals were examined in comparison with that of the standard S. aureus ATCC29213 strain.

使用万古霉素体外诱导方法将h-VRSA在体外逐渐诱导为VISA，通过对侵袭性酶、毒素的检测及动物致病性观察，并与金黄色葡萄球菌标准菌株比较，了解其致病性的变化规律。

Effects of Quercetin on invasion and midkine expression of human esophageal cancer cell.

槲皮素对食管癌细胞侵袭和中期生长因子基因表达的影响。

Objective The expression of iNOS bFGF CyclinD1 erbB-2 were studied by immunohistochemistry to investigate the relationships between the expression of iNOS and proliferative index of breast carcinoma such as bFGF CyclinD1 and erbB-2.The relationship between expression of iNOS and ages menstruous status tumor size histological stage TNM stage venous invasion ER PR lymph-node metastasis distant metastasis and survival rate in 5 years.

目的 研究诱导型一氧化氮合酶(Inducible Nitric Oxide，iNOS)在乳腺癌中的表达及与乳腺癌增殖指标碱性成纤维细胞生长因子、细胞周期素D_1(CyclinD_1)、癌蛋白(erbB-2)的关系，同时研究iNOS与年龄、月经状况、肿瘤大小、肿瘤学分级、TNM分期、脉管侵袭、ER、PR、淋巴结转移、远处转移、预后的关系。

Methods Three pairs of primers have been designed according to the hilA of Salmonella spp., hemolysin of Proteus mirabilis and Staphylococcus aureus clone pSa-442 Sau3AI fragment and the anticipated PCR products were 580bp, 401bp and 256bp.

本研究依据沙门菌侵袭基因正调节蛋白基因、变形杆菌溶血素基因和金黄色葡萄球菌特异性pSa-442序列，运用Primer Premier 5.0分别设计3对特异性引物，预计PCR扩增的目的基因片段分别为为580bp、401 bp、256 bp。

Integrins are the major family of cell adhesion receptors that mediate cell adhesion to the extracellular matrix.

整合素主要介导细胞之间及细胞与ECM之间的黏附，并介导细胞与ECM之间的双向信号传导，对细胞的黏附，增殖，分化，转移，调亡起到重要的调控作用，在肿瘤的侵袭转移中发挥重要作用[14]。

Bachmann等［12］发现细胞核内Wnt5A基因表达越高，黑素瘤进展越慢，对瘤组织周围的侵袭能力也越弱。

The reference standard was any 2 of 5 tests positive: smear, aspirate culture, invasive-specimen PCR, filter paper PCR, and leishmanin skin test.

参考标准是任何5检验时2次呈阳性：涂片，抽吸物培养，侵袭性标本聚合酶链反应，滤纸PCR和利什曼原虫素皮肤试验。
