起重要作用

In addition, the studies of multisteps are focused on primary tumor lesions at different stages, but not on invasive and metastatic lesions.

观察在胃癌演进过程中起重要作用的两个分子事件，微卫星不稳定和TP53基因突变的改变。

Furthermore, treatment of the cultured tobacco cells with ABA also resulted in obvious increase in plasma membrane NADPH oxidase activity, and these enhanced effects of H2O2 production and NADPH oxidase activity induced by ABA were pronouncedly inhibited by two widely used mammalian neutrophil NADPH oxidase inhibitors, diphenylene iodonium and imidazole.

进一步研究发现，ABA能够显著升高质膜NADPH氧化酶的活性，而且ABA诱导H_(来源：A79BC论文网www.abclunwen.com)2O_2和NADPH氧化酶活性增加的效应能够被两个常用的NADPH氧化酶抑制剂碘二苯和咪唑显著抑制，这些结果说明，质膜NADPH氧化酶在悬浮细胞ABA诱导的H_2O_2快速产生中起重要作用。

The ET and NO produced locally in renal play more important role in the development of proteinuria.

BACKGROUND: Researches show that erythropoietin can stimulate the proliferation and protraction of endothelial progenitor cells to form new vessels, so EPO may play an important role in proliferation and differentiation of bone marrow-derived mesenchymal stem cells.

背景：促红细胞生成素能够促进内皮祖细胞增殖、迁延形成新生血管，因此促红细胞生成素可能在骨髓间充质干细胞增殖分化中起重要作用。

(1)The levels of MCP-1 and VEGF'levels was significant increased in CHD patients,Compared with controls, It was implicated that they might take part in the actions of informing atherosderotic plaques;(2)The serum level of MCP-1 and VEGF were elavated step by stey among the group of controls、SAP、UAP、AMI, It was thought they might develop the matter on the stability of atherosderotic plaques;(3)The serum level of MCP-1 and VEGF were positive correlated with 7-TIMI risk score, It prompt that MCP-1 and VEGF was the reactiveness markers of coronary artery process ,and developed the risk to major acute cardiac events.

(1)血清MCP-1、VEGF水平在冠心病患者中显著升高，提示MCP-1、VEGF可能在促进冠状动脉粥样硬化斑块形成的过程中起重要作用；(2)血清MCP-1、VEGF水平在对照组、各冠心病亚组(SAP、UAP、AMI组)之间逐级升高，提示MCP-1、VEGF可能增加了冠状动脉粥样硬化斑块的不稳定性；(3)联合检测MCP-1、VEGF的灵敏度\特异度上升，证明临床上联合检测二者血清指标意义大；并且血清MCP-1、VEGF水平和7-TIMI积分呈正相关性，7-TIMI积分高的患者血清MCP-1、VEGF水平也高，说明它们能作为冠脉病变的活动性标志物，可能成为评价主要心血管恶性事件的危险性的相关指标。

It indicates that VEGF is involved in the resorption of fracture healing and may be play an important role.
