Conclusion : JSI has good cardiac protective and anti-oxidizing effects .

病理损伤较mEC组轻。结论：肌生注射液具有很好的心脏保护及抗氧化作用。

Objective : To observe the effect of Jisheng injection ( JSI ) in protecting heart .

目的：观察肌生（GL）注射液的心脏保护效果。

If exact JSI was not available , however , an iteratively joint jammer state estimation and decoding algorithm was proposed .

同时，在无法得到精确干扰状态信息的情况下，提出了一种迭代干扰状态估计及译码算法。

Methods : Isolated heart of rat was preserved in modified Euro-Collins solution ( mEC ) containing JSI for 20 hrs , and that preserved in simple mEC was taken as control . Then Langendorff isolated rat heart perfusion was conducted .

方法：在改良的Euro-Collins心脏保存液（mEC液）中添加肌生注射液，以单纯mEC液为对照组，保存大鼠离体心脏20h，采用Langendorff离体鼠心灌注法，于再灌注40min，测定心功能、冠脉流量及心肌含水量。

In this chapter , an algorithm of iterative estimating jamming state information is proposed specially for OFDM systems based on linear modulation so as to gradually improve the correct rate of estimating JSI with the iterative estimation and then improve the performance of the whole system .

本章还专门针对基于线性调制的OFDM系统提出了一种迭代估计干扰状态信息的算法。通过迭代估计干扰状态信息，其准确性逐渐提高，从而也提高了整个系统的抗干扰性能。
