Lumsden,Promethean Fire:Reflections on the Origin Of Mind(1983,with Charles J. Lumsden),Consilience:The Unity of Knowledge(1998),Wilson developed his thought of the human sociobiology,and tranfered the common form of the evolutionary theory to the theory of gene-culture coevolution,and explored the mutual relationship and evolutionary mechanism of the gene,spirit and culture.And,he claimed to reconstruct the basis of social science through researching the structure of human nature,to bridge the gap between the natural science and the social science.

随后，在《论人性》(1978)、《基因、精神与文化》(1981，与查尔斯·拉姆斯登合著)、《普罗米修斯之火》(1983，与拉姆斯登合著)和《论契合：知识的统合》(1998)中，威尔逊发展了他的人类社会生物学思想，探索基因、精神、文化三种因素相互关联和协同进化的机制，并主张通过对人性深层结构的研究来重建社会科学的基础，从而架设一座由自然科学通往人文社会科学的桥梁。

Two different murine models (IFN γ or IL 4 gene knockout C57BL/6 mice,15 mice each strain) were contagiously infected with P.carinii by cohousing with P.carinii positive mice for 3,5,7 weeks as well as 15 gene un knockout C57BL/6 mice for infection control group.

分别用IFN γ或IL 4基因敲除的C5 7BL 6小鼠(各 15只作为动物模型)与未经基因敲除的C5 7BL 6小鼠(15只作感染对照组)，以密切接触的方式，使小鼠自然感染卡氏肺孢子虫；同时设非感染组 15只小鼠作阴性对照。

The prolactin gene was studied as a candidate gene for the prolificacy of five different sheep breeds, namely small tail Han sheep (142), Hu sheep (40), Texel sheep (36), Dorset sheep (36) and Corriedale sheep (28). Single nucleotide polymorphisms of PRL coding sequence were detected among these five sheep breeds.

本研究以小尾寒羊(142只)、湖羊(40只)、特克塞尔羊(36只)、多赛特羊(36只)和考力代羊(28只)这五个绵羊品种为实验材料，应用PCR-SSCP对PRL基因的DNA编码序列的多态性进行了分析，并进一步对该基因与小尾寒羊高繁殖力之间的关系进行了研究。

Polymorphism was detected for exon 3 of BMP4 gene in four sheep breeds. For exon 3, three genotypes were detected in four sheep breeds. In Small Tail Han, Chinese Merino, Corriedale and South African Mutton Merino sheep, frequency of genotype AA was 0.017, 0.216, 0.115, 0.429, frequency of genotype AB was 0.102, 0.317, 0.269, 0.500, frequency of genotype BB was 0.881, 0.467, 0.616, 0.071, respectively. Sequencing revealed one singlenucleotide mutation C→A at 305 bp of exon 3 of BMP4 gene in genotype BB in comparison to genotype AA, and this mutation resulted in an amino acid change of alanine→aspartic acid.

对于外显子3的引物，在4个绵羊品种中都检测到3种基因型；统计结果表明：小尾寒羊、中国美利奴绵羊、考力代绵羊、南非肉用美利奴绵羊AA基因型频率分别为0.017、0.216、0.115、0.429，AB基因型频率分别为0.102、0.317、0.269、0.500，BB基因型频率分别为0.881、0.467、0.616、0.071；测序结果表明：BB型和AA型相比在BMP4基因外显子3第305位碱基处发生C→A的突变，该突变导致氨基酸由丙氨酸改变为天冬氨酸；BB型小尾寒羊平均产羔数分别比AB型和AA型多0.61只（P.05）和1.01只（P.05）。

Although direct lethal effects on cotton boll worm couldn't be generated in tobacco plants transformed with cholesterol oxidase full gene vector or mature enzyme gene vector, inhibitory effects on the growth and development of cotton boll worm have been observed to a certain degree.

转单价胆固醇氧化酶全酶基因和成熟酶基因的转基因烟草植株均不能对棉铃虫产生直接的致死作用，但能使棉铃虫的生长发育受到一定程度的抑制。

Methods The distribution of the calcitonin gene-related peptide-immunoreactive fibers in the cremaster arteries had been studied by means of ABC technique.Results The calcitonin gene-related peptide-immunoreactive fibers were observed on all branches of cremaster arteries.

方法采用免疫组织化学ABC法对大白鼠提睾肌动脉各级分支的CGRP免疫反应阳性纤维的分布特点进行观察和研究。

Both chrysotile and crocidolite at given dose could stimulate type Ⅰ and type Ⅲ collagen gene expression by 2ES cell, suggesting that asbestos fibre itself may also contribute to collagen gene expression in asbestotic lung 〓.

一定剂量的温石棉和青石棉都可以刺激2BS细胞Ⅰ、Ⅲ型胶原基因的表达，表明石棉纤维本身也是引起石棉肺病变中胶原基因表达增加的重要原因。

Using molecular beacon probe to examine the mRNA expression level of SRG2 gene in cryptorchid testis of various stages,we found that the gene was up-regulated distinctly.

应用新型的分子信标检测该基因在不同时期隐睾中的mRNA表达水平，发现该基因呈明显上调，证明该基因在隐睾的发生发展中具重要作用。

The origin analysis on the source of hosts and terrains was carried out on the base of homology tree and phylogenetic tree founded in 19 isolates on their CP gene nucleotide sequences. The result showed that the gene types and clusters of Cucumber green mottle mosaic virus were not obviously related to the two factors.

对包括该分离物在内的19个CP基因核苷酸序列进行同源性比较和系统进化树构建，并结合寄主来源及地域来源进行LHP的起源分析，结果表明黄瓜绿斑驳花叶病毒不同分离物的序列分群和进化关系与上述两个因素无明显关系。
