This study showed that population genetic diversity was much lower than other Gymnosperm and there was no distinct genetic differentiation among individuals in this population. In order to protect or preserve its genetic resource,it is suggested that the most individuals in the population should be selected as we can.

研究结果表明：AFLP方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。

KIR bind corresponding HLA-Ⅰmay hame four results followed:1、When inhibitory KIR bind HLA-Ⅰand there has no activatory KIR bind it,cell isn\'t dissolve because inhibitory signal access was done;2、When activatory KIR bind corresponding HLA-Ⅰand there has no inhibitory KIR bind it,form activate signal,lead cell dissolve.3、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when activatory signal play the main role,NK cell still actived,lead target cell dissolve.4、If activatory or inhibitory receptor both bind HLA-Ⅰ,both signal access is make done,when inhibitory signal play the main role,or both signal access don\'t play,NK cell do not make effect.this is NK cell recognice nomal tissue.

与活化型KIR受体相比，抑制型KIR受体与HLA-Ⅰ类抗原结合的亲和性更强，当抑制型和活化型KIR受体识别和结合同一HLA-Ⅰ类抗原分子时，以抑制作用为主。KIR与相应HLA-Ⅰ结合后可能产生以下4种情况：①当抑制型KIR与HLA-Ⅰ结合而无活化型KIR与HLA-Ⅰ相互作用时，因抑制信号通路启动而不产生细胞溶解；②当活化型KIR与靶细胞表面的相应HLA-Ⅰ结合同时无抑制型KIR与HLA-Ⅰ的相互作用时，形成刺激信号通路，导致靶细胞溶解。

The genetic distances to resistant gene are 9.6 cM and 10.4 cM, respectively. The resistance to sorghum head smut physiological race 3 may be controlled by two mutual independent nonallelic genes, and there is interaction between them. It is found that molecular markers are easier to find in B population than R population during the screening of SSR markers. It may show the different resistance mechanism between restorer line and maintainer line.

高粱对丝黑穗病菌3号生理小种的抗性可能受2对彼此独立的非等位基因控制，并且基因之间存在着互作；筛选SSR标记时发现，高粱抗丝黑穗病基因的分子标记较易在保持系群体中找到，在恢复系群体中DNA片段多态性较少，表明恢复系和保持系在抗性机制上可能存在差异。

Helleri RR-B strain and the average homozygote rate reached 100%. These loci could be used as markers in genetic monitoring of X. helleri RR-B strain, which had obtained fairly high genetic homozygosity by inbreeding for more than 20 generations.

结论］18个微卫星座位可作为剑尾鱼RR-B系遗传监测的分子标记；剑尾鱼RR-B系经20多代的近交培育已具有很高的遗传均一性。

Thus, these data could be deduced that hemocyanin indeed present homology with IgSF molecules.

提示，血蓝蛋白确实与IgSF分子具有同源性。

Objective: To observe the effects of low molecular weight heparin during hemodialysis in HD patients with active bleeding.

目的 ：观察低分子肝素在伴有各种活动性出血患者血透中的应用。

OBJECTIVE: To summarize the advances in the genetic susceptibility to coronary artery disease and explore the heritable basis of the disease.

目的：概述冠状动脉粥样硬化性心脏病遗传易感性的研究进展，探讨冠心病的分子遗传学基础。

Pike protein consists of S1 and S2 subunit. S1 is head and S2 is rod-shape part, intermolecular effort can bind each other. S1 can bind with host cell epimembranal acceptor. S2 can fix integral Spike protein on the cellular membrane and mediate cell-fusion with virus and host cell. There are significant antigen determinant of virus in Spike protein, genic heterogenesis can effect viral pathogenicity. SARS-CoV Spike protein, which has 23 pieces larvaceous glycosylation sit, consists of 1256 amino acid. Its N-terminals and C-terminals is corresponding conservative.

蛋白是I型膜糖蛋白，介导病毒与宿主细胞膜上的受体结合并与宿主细胞膜相融合。S蛋白由S1和S2两个亚基组成。S1形成球状部分，S2形成棒状部分，两者之间通过分子间的作用力相互结合。S1能与宿主细胞上的受体结合，S2可把整个S蛋白固定在细胞膜上，并介导病毒包膜与宿主细胞膜融合。S蛋白上有重要的病毒抗原决定簇，S基因的突变会影响病毒的致病性。

The results show that the primers S37 and S61 are of apparently specific to the amplified bands of six strains, which establishes the basic for the degenerate molacular marker of Cordyceps militeris and confirms heterokaryosis and parasexuality of Cordyceps militeris.

结果表明，引物S37、S61对6个菌株的扩增谱带具有非常明显的特异性，该结果为蛹虫草退化分子标记奠定基础，并且在一定程度上也印证了蛹虫草异核现象和准性生殖理论。

Then the PMAA molecules were modified on the array membranes, molecular transport under different pH value was investigated by fluorescence measurements using tris(22-bipyridyl) dichlororuthenium hexahydrate and quantum dots as probes.

接着将PMAA分子修饰到氨基化金纳米通道阵列膜上，以联钌吡啶和水溶性量子点为探针考察了不同pH值下膜的渗透性。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
