A clear cause-and-effect relationship between excessive myocardial MMP-1 activity, increased mysial collagen degradation, and progression to systolic HF has been shown experimentally through the use of transgenic models and the use of pharmacological MMP activators.53,54 In addition, experimental evidence has been provided showing that following chronic neurohormonal activation, increased synthesis and release of MMPs into the local extracellular matrix of the cardiomyocyte occurs,55 which in turn could contribute to endomysial and perimysial collagen degradation and disruption.

Result 1 Magnetic nanoparticles, magnetic nanoparticles modified with antisense oligodeoxynucleotide of human telomerase reverse transcriptase induced HL-60 tumor cells to apoptosis, we could see typical morphologic change of apoptosis cells: karyopyknosis, chromation"s condensing and aggregation in nuclear, forming crescent-shaped or annulus structures to lean on edge of cell nucleus"s membrane and posing apoptosis body by Atomic Force Microscope, Fluorescence microscope, transmission electron Microscope 2 There was a significant difference compared with control group(p.01), inhibition ratio had significant positive correlation with medication dosage and time ;during 0.8-8μM dosage amplitude, inhibition ratio accrescenced by dosages increasing. However, the inhibition ratio would decrease when dosage over 8-80μM.

结果 1 磁性纳米粒子、修饰有端粒酶反义寡核苷酸的磁性纳米粒子诱导HL-60细胞发生凋亡，原子力显微镜、光学显微镜、荧光显微镜和透射电镜下均观察到HL-60细胞呈现典型的凋亡细胞的形态变化：细胞核固缩，核内染色质浓缩、凝聚、形成新月形或环状结构紧靠在细胞核膜边缘，并形成凋亡小体。2 磁性纳米粒子、修饰有端粒酶反义寡聚脱氧核苷酸的磁性纳米粒子对HL-60肿瘤细胞的生长和增殖有明显的抑制作用，与对照组相比有显著性差异(p＜0.01)，在剂量为0.8-8μmol／L范围内，抑制率随剂量的增加而增加，当剂量超过8μmol／L时，抑制率反而下降；3 磁性纳米粒子、修饰有端粒酶反义寡聚脱氧核苷酸的磁性纳米粒子可增强p53基因的表达活性，引起DNA降解损伤，反向调节细胞周期活动，促使细胞从G0期进入G1期，抑制肿瘤细胞的生长。4 修饰有端粒酶反义寡聚脱氧核苷酸的量子点能通过内吞作用进入HL-60肿瘤细胞的细胞核，可以在细胞内进行定位和促进HL-60肿瘤细胞的凋亡。

Here, similarities between archaebacteria and eukarykaryotic otic cells in many aspacts including DNA duplication, transcription, translation and histones, chromatin, proteasome were introduced. Finally, the evolutionary position of archaebacteria and their significance to onery gin of the eukaryotic cells were discussed.

P＜0.01. 28d, q=4. 0452, p＜0.05 . Corresponding pathologic result shows that the corneal stromal of height edema increase thickness to have infiltration of inflammation cells with hyperplasia of fibroblast cell and large vessel. The collagen fiber in stromatic layer is dissolved and destroyed seriously, suggesting that in addition to HSV-1's direct destructuring effect, inflammatory cells that might play an important role in the pathology of HSK induce the immune-pathological reaction.
