(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。

Two knotty problems are confronted constantly in the design process, one is the design sensitivity analysis and another is the fast reanalysis of structures which are modified.

According to this method,four different 11-step algorithms with four different window functions which are rectangular window,triangle window,hanning window,and blackman window are designed. Analysis and simulation show that hanning window and blackman window with small lobes are less sensitive to errors. Seven different algorithms with the same phase shifting interval π/2 are designed by hanning window function,whose phase shifting steps are separately 5,11,15,39,51,76 and 101 steps.

选择矩形窗、三角窗、hanning窗和blackman窗生成4种11步移相算法，对振动误差和相移误差的分析验证了旁瓣小的hanning窗和blackman窗生成的算法对误差的灵敏度要小；再选择hanning窗生成了移相间距为π/2的5，11，15，39，51，76和101步7种移相算法，仿真验证了步数越多主瓣越小，对振动抑制能力越好，但需要更高的微位移器移动精度来获得有效的干涉条纹。

Compared with the gold standard of clinical diagnosis by a pediatric neurologist who had not seen the pictures,headache drawings depicting pounding pain, nausea or vomiting, recumbency, periorbital pain, photophobia, or visual scotoma had a sensitivity of 93.1%, a specificityof 82.7%, and a positive predictive value of 87.1% formigraine.
