Treatment of edaravone markedly reduced the content of MDA and the expression of Caspase-3 in comparison to the ASCI control group, while the expression of Bcl-xl was obviously higher in the ASCI treatment group than that in the ASCI control group.

结果：ASCI盐水组MDA含量、Caspase-3阳性细胞表达和Bcl-xl蛋白表达水平均明显高于假手术组；与盐水组相比，依达拉奉治疗组MDA含量和Caspase-3阳性细胞表达水平均下降，而Bcl-xl蛋白表达水平显著增高。

The results show that all the hmgr genes from pigs, cattle and chickens are astable enzyme proteins with the same gene sequence characteristics and encoding protein and physical and chemical properties; all the amino acid sequences have a high degree of homology, containing two conservative HMG-CoA binding motifs and two NADPH binding motifs; all the amino acid sequences, containing signal peptide, are secreted proteins; they are all hydrophobic transmembrane proteins with five transmembrane domains; random coil and α-helix are the main structural elements in the HMGR polypeptide chain; all the predictions of three-dimensional structure are V- shaped; there are more closer evolution relationship between the HMGR gene from pigs and cattle.

结果表明：猪、牛和鸡HMGR基因序列特点及编码蛋白质理化性质基本相同，均属不稳定类酶蛋白；保守结构域氨基酸序列具有高度的同源性，均含有保守的2个β-羟基-β-甲基戊二酸单酰辅酶A结合基序和2个还原性烟酰胺腺嘌呤二核苷酸结合基序；均有信号肽，属分泌型蛋白质；属于跨膜的疏水性蛋白，均有5个跨膜结构域；无规则卷曲和α-螺旋是HMGR多肽链中的主要结构元件；三维结构预测都呈"V"字形；猪和牛HMGR基因的进化关系最近。

目的 探索天然抗角蛋白自身抗体对培养角质形成细胞及鳞癌细胞凋亡相关蛋白的表达影响。

Objective To investigate the expressions of Survivin protein and nm23 protein and the relationship among the expressions and axillary lymph node metastasis in breast cancer.

目的：探讨凋亡抑制蛋白Survivin和转移抑制蛋白nm23在乳腺癌组织中的表达及与腋淋巴结转移和5年生存率的关系。

The results show that firstly, ApoE and LDL receptors can be transported bidirectionally (i.e. retro-and anterogr-adely) in the axoplasm along axons. Secondly, ApoE derived from regenerating fillers can be transported re t rogradely to the cell bodies.

本文用免疫细胞化学法研究正常和再生的大白鼠外周神经中脱辅基脂蛋白E和低密度脂蛋白受体的运输特性，发现在正常的外周神经中，ApoE及LDL受体在轴浆中均可沿轴突正行和逆行运输；再生的神经可产生ApoE，ApoE可逆行向细胞体转运。

Compared with SDS-PAGE results of the development season barks, there were six 12, 30, 32, 38, 40, 53 kD major proteins expressed in the dormancy season barks, which was probably the vegetative storage protein of Melia azedarach L.

SDS-PAGE结果表明：休眠期枝条中的蛋白条带数目明显多于生长期枝条且浓度高，有12、30、32、38、40、53kD 6条蛋白带在休眠期枝条细胞中大量特异表达。

H2-uptake phenomenon of the bacterial ferritin is still found in an analogy system of micro-oxygen environment of entire cell Azotobacter vinelandii in vitro, which indicates that the H2-uptake reaction can be carried out by the ferritin within the cell.

此外，细菌铁蛋白在体外模拟棕色固氮菌整体细胞内的微量氧环境体系中仍有氢还原现象，因而推测细菌铁蛋白在该菌体内也能进行吸氢反应。

Key to this targeted treatment is Azurite, a crystal formed in sea beds that helps promote the collagen and elastin network where support is needed most.

解决这一问题的关键是有针对性的治疗Azurite ，一个晶体形成的海床，帮助促进胶原蛋白和弹性蛋白，支持最需要的。

To better understand the roles of LsrA protein in nodulation, a series of analyses of nodules using scanning electron microscopy, genetic and biochemical approaches have been carried out. Our analyses suggest that the lsrA1 nodules contain bacteroids in the invasion and establishing zone only. The lsrA gene expression is active early in the invasion zone and activated later than bacA genes. The lost of LsrA protein dramatically reduced the expression of nifA and fixK, and completely blocked the expression of the nifH gene for nitrogenase. LsrA protein functions early in the bacteroid development and it is essential for the development nitrogen fixing bacteroids.

前期的工作中，苜蓿中华根瘤菌Rm1021中90个候选LysR基因已经被定向插入突变，并筛选在自生生长时期、共生生长时期的表型，以期寻找更多在自生状态或共生固氮中有功能的LysR转录因子。1 针对前期鉴定出的共生固氮必需的lsrA基因，我们应用了一系列扫描电子显微镜技术、生物化学、分子遗传学等方法，发现lsrA基因主要在根瘤侵染区开始表达，表达时序也在侵染阶段左右，但晚于bacA基因表达；LsrA蛋白缺失后根瘤固氮区中缺乏具有固氮能力的类菌体，nifA和fixK基因的转录水平降低，nifH基因的转录被完全阻断，因此LsrA蛋白为根瘤发育所必需，是新的根瘤发育信号传导途径成员。2 通过表型筛选我们鉴定了苜蓿中华根瘤菌的oxyR基因，并研究了它的调节特性。oxyR突变后，苜蓿中华根瘤菌对过氧化氢敏感性提高，适应性降低。
