2In the period of planned economy, the three-stage of developmental phases of political culture determined the three-stage of developmental phases of scientific and technical system: the centralized political culture brought the absolute magisterial status of state scientific research institution in installation of organizational institutions, the flexuous development of political culture brought the scientific and technological system into chaos, the rational return of political culture promoted to resume and reconstruct scientific and technological system.

2计划经济时期政治文化发展的三阶段决定了科技体制发展的三阶段：高度中央集权的政治文化带来国有科研机构在科技体制组织体系设置中的绝对主导地位、政治文化的曲折发展带来科技体制的混乱、政治文化的理性回归促进科技体制的恢复与重建。

A cDNA segment was isolated from M. meretrix larvae. The results of caspase in situ detection in larval developmental stages revealed that there were activated caspase from L1 to L3, indicating caspase is involved in the whole developmental process. The main apoptosis area was found in velum at L3 before metamorphosis, indicating the degradation of velum might be the process of apoptosis. The larvae before metamorphosis were treated by caspase specific inhibitor to analyze the role of caspase in this process. The results indicated that caspase have function metamorphosis.

根据caspase在不同物种中的保守区域设计简并引物，在文蛤幼虫中扩增到cDNA序列片段；检测有活性的caspase在文蛤幼虫各发育时期的分布部位，发现其在L1至L3期幼虫中都有分布，说明整个幼虫形态变化过程中都有caspase的参与；细胞凋亡检测结果显示，幼虫主要发生细胞凋亡的部位在L3期幼虫的面盘，即变态过程中要退化的器官，说明细胞凋亡可能是文蛤幼虫变态过程中面盘退化的主要机制；用caspase特异性抑制剂处理变态前幼虫，发现幼虫变态率下降，初步验证了caspase在文蛤幼虫变态过程中的作用。
