During the titration of Ca〓CaM by La〓, the hydrid complex La〓Ca〓CaM forms as the intermediate species. La〓 can bind to calmodulin with high affinity (K〓=10nmol/L) and obvious cooperation between the two global domains. The secondary structure of La〓CaM and Ca〓CaM are highly similar, but there are obvious differences in ternary structures. Excessive La〓 changes the conformation of calmodulin greatly.

实验结果表明，La〓在钙调蛋白上的结合位点与钙离子相同；在结合顺序上La〓以较小的优势先结合在钙调蛋白的N末端；La〓Ca〓CaM是La〓与含钙的钙调蛋白作用时的主要产物；La〓强烈地与钙调蛋白结合，其解离常数约10nmol/L，各个结合位点之间存在明显的协同效应；La〓CaM与Ca〓CaM在二级结构上高度相似，但是在高级结构上有明显差异。

Lymphy node metastasis in Uygur patients were greater than Han patients in Ⅰ~Ⅱgrade and Ⅲ grade (X~2=13.14, P.001; X~2=5.08, P.05).(3) The proportions of the expression of VEGF-AmRNA and its protein were 31.8%、 57.1%、64.3%, 27.3%、 53.6%、 59.5% in difference pathological grade in 92 samples, With increasing of the pathological grade,the VEGF-AmRNA and its protein expression are highly (X~2=6.26, P.05; X~2=6.21, P.05); The proportions of the positive expression of VEGF-AmRNA and its protein were 68.4

392例浸润性乳腺癌组织中VEGF-AmRNA和其蛋白的表达在不同组织学分级中其阳性率分别是31.8%、57.1%、64.3%，27.3%、53.6%、59.5%；二者在不同组织学分级中表达差异具有统计学意义(X~2=6.26，P.05；X~2=6.21，P.05)；在淋巴结转移组与非转移组中VEGF-AmRNA和其蛋白的表达阳性率的分别是68.4%、31.49，61.4%、31.4%，在淋巴结转移组VEGF-AmRNA和蛋白的明显高于淋巴结未转移组(X~2=11.96，P.001；X~2=7.79，P.05)；VEGF-AmRNA和其蛋白的表达

Results Although overexpression of P53 protein was not detected in normal eyelid cutaneous epithelium, meibomian gland and mild epithelial dysplasia, the positive rate of P53 increased in degree in moderate and severe dysplasia, carcinoma in situ and invasive tumors, and PCNA labeling index progressively increased too. Overexpression of P53 protein was detected in 30/53 cases of basal cell carcinoma, 16/32 cases of squamous cell carcinoma, 10/17 cases of meibomian gland carcinoma, and the intensity of P53 protein immunostaining increased with the lowering in the degree of histological differentiation.

结果 在正常眼睑皮肤、睑板腺及轻度不典型增生眼睑上皮中，未见P53蛋白表达，而中、重度不典型增生，原位癌，浸润癌中，P53蛋白阳性表达率逐渐增高，其 PCNA指数也有增加趋势。30/53例基底细胞癌(basal cell carcinoma，BCC)、16/32例鳞状细胞癌（squamous cell carcinoma，SCC）、10/17例睑板腺癌中，P53蛋白阳性表达；同时，随着肿瘤组织分化程度的降低，P53蛋白阳性表达程度有逐渐增高的趋势。

Most recently the group is mainly engaged in some important protein related to health and diseases, including human Cul3 ubiguitin ligase complex, some effectors and eritical proteins of pathogenic bacterical, and a series proteins critical in aromatic degradation pathway of microbal.

近年来的主要研究对象为一些与天然免疫相关的重要蛋白，包括一系列天然神经毒素，抗微生物蛋白，抗肿瘤蛋白和抗病毒蛋白，以及还开展了造血干细胞和痢疾杆菌的结构基因组学研究。

High dose copper induced decrease ofⅠ,Ⅱ,Ⅳ-2 content and increase ofⅢof spectrin. High dose copper can also decrease SA, PE content and increase SM, PS content.These showed that high dose can induce injury of erythrocyte by changing elementary structure and moity of membrane protein and membrane phospholipid, which may be one of the mechanisms of goat erythrocyte damage induced by high dose copper. 2. High copper caused the decrease of SOD and GSH-PX activity and the increase of MDA content.

高铜能引起红细胞膜收缩蛋白Ⅰ、Ⅱ及区带Ⅳ-2蛋白含量均显著降低，而区带Ⅲ蛋白含量明显增高，红细胞膜唾液酸含量降低，磷脂酰乙醇胺含量降低，神经鞘磷脂和磷脂酰丝氨酸含量升高，表明高铜能够改变红细胞膜蛋白和磷脂等基本结构和组成成分，这可能是高铜致羊红细胞损伤的机制之一。

A potential approach to this problem is to make use of a natural defense mechanism called " the stress response," which is characterized by a transient down - regulated synthesis of nonvital cellular proteins and increased production of endogenous protective factors known as heat shock proteins that act to allow proper refolding of proteins denatured by the incipient injury.

应激反应的特征是一过性下调细胞非必需蛋白的合成及增加被称为热休克蛋白的内源性保护因子的合成。热休克蛋白作用是促使损伤导致变性的蛋白适当地再折叠。HSP家族中HSP70被认为在细胞保护中发挥重要作用。
