1、Cur inhibits K562 cells growth and induces cell apoptosis may be correlated with the down-regulation of p210~、inhibition of protein tyrosine phosphorylation and the signaling molecules such as p-Erk1/2、c-myc which are relevant with cell growth and apoptosis; 2、Cur synergizes STI571 to inhibit K562 cell growth and induce cell apoptosis may be correlated with the down-regulation of p210~、inhibition of protein tyrosine phosphorylation and the signaling molecules such as Hsp90、PKC which are relevant with cell growth and apoptosis; 3、Cur reverses the resistance of K562/G01 cells to STI571, and synergizes STI571 to inhibit K562/G01 cell growth and induce cell apoptosis; 4、Cur inhibits human originated CML CD34~+ cell growth、induces cell apoptosis, and enhances STI571 to down-regulate the expression of p210~, finally inhibit cell growth and induce cell apoptosis.

从以上实验结果我们得出如下结论： 1、Cur抑制K562细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制下游p-Erk1/2、c-myc等信号分子有关； 2、Cur协同STI571抑制K562细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制Hsp90和下游PKC等信号分子有关； 3、Cur可逆转K562/G01细胞对STI571的耐药性，并与STI571协同抑制K562/G01细胞增殖和诱导凋亡，其抑制K562/G01细胞增殖、诱导细胞凋亡的作用可能与其下调p210~、蛋白酪氨酸磷酸化水平以及抑制下游Procaspase-3和NF-κB等信号分子有关； 4、Cur可抑制来源于CML患者骨髓的CD34~+细胞的增殖并诱导其凋亡，还可协同STI571下调CML CD34~+细胞p210~表达，进而协同抑制细胞增殖、诱导细胞凋亡。

Response time is defined as the same point in the panel above to change from black and white plus the time required for change from white to black response time LCD there is a matter of time because the LCD is based on the rotation angle of liquid crystal molecules to control the light light and dark gray rotation of liquid crystal molecules will take time. the general aim is to monitor the use of word processing and web browser is under normal circumstances will continue to monitor display screen with a long period of time, then switch to a different picture of such a In fact, the use of fast response time more than slow the user is not affected but if you want to use animation or video monitor view will continue to change because the screen did not stop this time the response time will affect the picture quality.

坏点所谓坏点，是指液晶显示器上无法控制的恒亮或恒暗的点，坏点的造成是液晶面板生产时因各种因素造成的瑕疵，可能是particle落在面板里面，可能是静电伤害破坏面板，可能是制程控制不良等等等，坏点分为两种：亮点与暗点，亮点就是在任何画面下恒亮的点，切换到黑色画面就可以发现，暗点就是在任何画面下恒暗的点，切换到白色画面就可以发现，一般来说，亮点会比暗点更令人无法接受，所以很多monitor厂商会保证无亮点，但好像比较少保证无暗点的，有些面板厂商会在出货前把亮点修成暗点。
