12H treatment group compared with 12h model group: the level of MCP-1 of the Gardenoside group decreased and MIP-1 is no different with the model group; the level of the MCP-1, MIP-1 of the Baicalin group are no different with the model group; the level of MCP-1, MIP-1 of the Concha Margatitifera Usta decreased than the model; the level of MCP-1 of the Cholic Acid group is no different and the level of MIP-1 decreased than the model; the level of MCP-1 of the Hefang Group decreased and the level of MIP-1 of it decreased than the model group.

合方治疗脑缺血24小时组缺血脑组织nNos光密度值较缺血24小时模型组明显降低（p＜0.01）。细胞的死亡分为坏死和凋亡两种方式，凋亡是细胞为避免对机体造成更大损伤而采取的一种程序性的死亡方式。珍珠母、胆酸、栀子苷、黄芩苷、合方治疗组较脑缺血24小时模型组可明显降低P53阳性表达，考虑药物抑制细胞凋亡可以起到对缺血脑组织的保护作用。

The paper describes a new iterative decoding algorithm for the product codes, its feedback method is completed by a linear combination of soft output of encoder and the receipt information is different with the traditional turbo iterative decode. When decoder obtains the soft output matrix built -1 and +1, the complexity can be reduced greatly and the performance can be lost utile by reducing the number of candidate code words and omitting the complicated operation of LLR.

针对乘积码提出一种新的迭代解码算法，该算法的反馈方式有别於Turbo码的传统迭代译码，是通过输出软信息与接收软信息进行线性叠加来实现的，此时子译码器的候选码字个数将大为降低，同时译码输出也无须做复杂的LLR计算，直接映射为由-1，+1组成的软输出矩阵，从而在牺牲较小性能的情况下很大程度地降低了译码复杂度。

结果 血透患者在透析前的必需氨基酸除苯丙氨酸外均较正常对照组降低，其中以缬氨酸、亮氨酸和组氨酸下降为显著；非必需氨基酸中精氨酸、甘氨酸和鸟氨酸明显升高；酪氨酸/苯丙氨酸和丝氨酸/甘氨酸的比值较对照组明显降低。

The synthetic evaluation of soil biology---biological fertility indices were (0-40cm depth of soil, same below): 0.635 →0.074 →0.014 . Significant degradation of soil texture, obvious decrease of soil organic matter , and increase of the availability of aluminum were found in the degradation series. Along with the fast vanishment of vegetation, the number of soil microbe and enzymatic activities decreased drastically, among which protease activity degraded most markedly and was only detected in soil of ZR.

土壤物理性质中，土壤质地发生了根本性退化；土壤化学性质中，随着植被的退化，有机质含量的减少和Al的有效性的提高都很明显；土壤微生物和酶活性中，各类微生物的数量退化非常显著，其活性也随植被的退化急剧减弱，酶活性也大大降低，以蛋白酶活性降低最为显著，大部分退化地段未检测出蛋白酶的活性。

It may reduce the temperature in cities, shorten the tart-up frequency and the operating time of fridges and air-conditioner, diminish the transformation of electric energy to thermal energy and cut down sunlight heat's sucking the vapory if we create more green areas and increase the deposit of timber so as to store carbon dioxide in it.
