Feature extraction is one of the key problems in pattern recognition system.

特征提取是模式识别中的一个关键问题。

Results: pcDNA3.1+/TSP-1-Ⅰ veinal injection has stronger TSP-ltype Ⅰ repeat band than that of directly injection into myocardium (P＜0.05), while veinal injection of pcDNA3.1-/anti-TSP-1-Ⅰ has a slightly weak TSP-1 typeⅠ repeat band (P＜0.05), Western blot obtained the same result.

成功构建pcDNA3.1+/TSP-1-Ⅰ、pcDNA3.1-/anti-TSP-1-Ⅰ。作为血管新生抑制基因，在体外，TSP-1Ⅰ型重复序列基因编码的TSP-1Ⅰ型重复序列多肽，能够抑制ECV304细胞生长和增殖，其抑制机制与TSP-1Ⅰ型重复序列诱导ECV304细胞凋亡相关。
