At the same time, the construction of Chinese zebu core group based on haplotype il validated the distinct origin of Bos indicus in Tibet, which was different from that of the other cattle breeds with zebu haplotypes in China.

同时证明了西藏瘤牛独立于中国瘤牛核心类群的特殊性。

The mithun mtDNA showed the type of zebu cattle, indicating the close relationship between the origins of mithun and zebu cattle.

大额牛的限制性类型与瘤牛相同，表明大额牛的起源与瘤牛有密切关系。关键词云南黄牛，mtDNA，限制性类型

This indicates that Brahman cattle was one of the zebu breeds and inherited the excellent characteristics of both the Asian zebu and European beef cattle , such as easy calf delivery , high quality beef , heat tolerance and resistance to various parasites .

表明婆罗门牛的确是集亚洲瘤牛，欧洲普通牛等优良特性于一身(易产犊，产肉性能好，耐热与体表寄生虫等)的瘤牛品种之一。

The result shows that firstly,zebu ismost closely related to cattle;secondly,closely related to yak,buffalo,pig,human,lastly,related to rat and mouse.The results of the phylogenetic trees reflect the molecularevolution relationship among these species,consistent with the zoological classification.The genetic distances among yak,cattle and zebu were relatively small,but geneticdistances between these three species and buffalo were relatively large.

研究表明，牦牛、普通牛和瘤牛三个物种间的遗传距离远小于它们各自与水牛这一物种的遗传距离，三者之间的亲缘关系也相对于它们与水牛间的亲缘关系较近，故将牦牛、普通牛和瘤牛划分在同一个属—牛属，而将水牛划分在另一个属更为合理。

The first day after C6 cells were seeded in rats bearing glioma, these rats were abdominally injected PA at the dose of 550mg/kg/d, twice a day for two weeks or DMF 570mg/kg/d in the same way.

分别在荷瘤大鼠种植胶质瘤细胞C6后第1d，对大鼠进行苯乙酸550mg/kg/d，二次/日，连续两周腹腔注射，或二甲基甲酰胺570mg/kg/d，二次/日，连续两周腹腔注射治疗。

The distribution of NAT2 polymorphisms was different between the recurred group and the control group. The polymorphism of NAT2 would increase the risk of recurrence in the population with history of rectal adenoma. However, there is no difference for NAT2 rapid and slow acetylator between two groups.

NAT2多态性在腺瘤复发组与对照组中的分布是有差异，NAT2非野生纯合型(Wt/M〓+M〓/M〓)为直肠腺瘤复发的危险因子，特别当在非野生纯合型中的NQO 1 C/T+T/T型及MTHFR C/T+T/T，其相对危险度分别可达：3.27(95％CI 1.01-10.65，P＝0.043)和3.28(95％CI1.00-10.84，P＝0.046)。

It is suggested that the metabolism of heterocyclic amines generated from fried fish may be altered by genetic variability of NAT2. The rapid acetylator would increase the heterocyclic amines from pre-carcinogen to active formation.

NAT2多态性与吸烟有交互作用，特别是野生纯合型与吸烟交互作用可使直肠腺瘤复发危险度上升到22.75(95％CI 2.11-244.86，P＝0.007)，其机制可能为NAT2酶可能参与了烟草中产生的多环芳烃致癌物，从而涉及直肠腺瘤发生。

Results With the expression in normal salivary gland as a standard, low C-erbB-2 mRNA expression was seen in adenolymphoma, basal cell adenoma. However, various degrees of over-expression of C-erbB-2 oncogene mRNA were detected in pleomorphic adenoma, mucoepidermoid carcinoma,acinic cell carcinoma ,adenoid cystic carcinoma ,papillary cystic carcinoma,and myoethelial cell carcinoma.

结果 正常涎腺和涎腺肿瘤中发现不同程度C-erbB-2mRNA的表达，以正常涎腺组织的表达水平为基准，在腺淋巴瘤、基底细胞腺瘤呈现低表达、无表达或与正常涎腺组织表达水平相似，多形性腺瘤、粘液表皮样癌、腺泡细胞癌、腺样囊性癌、乳头状囊腺癌和肌上皮癌则呈现不同程度的过表达。

The members of the same genus and family were grouped together. The polyogenetic relationships of 8 families were Pyrgomorphidae →Chrotogonidae→Pamphagidae→Oedipodidae→Acrididae→Arcypteridae→Gomphoceridae→Cantantopidae.Pygomorphidae had closer relationships with Chrotogonidae as well as being the most ancestral group. Arcypteridae and Gomphoceridae were the sister groups and had closer relationships with most evolutionary Catantopidae. Tridactylidae was divided firstly as a suborder,which differs from the recent taxonomy distinctly. Haglidae and Gryllidae were grouped into suborder Ensifera, Tetrigidae and 8 families of Acridoidea were grouped into suborder Caelifera, as same as recent taxonomy.

分子系统树表明：科内的属和属内的种均优先聚在一起；蝗总科8科的起源关系为：锥头蝗科→瘤锥蝗科→癞蝗科→斑翅蝗科→剑角蝗科→网翅蝗科和槌角蝗科→斑腿蝗科；锥头蝗科与瘤锥蝗科关系较近，是蝗总科内最原始的类群；槌角蝗科和网翅蝗科互为姐妹群，与最进化的斑腿蝗科关系较近；蚤蝼科为独立的一支，最先分出，似为一个亚目，与现用的分类系统有明显差别；哈螽科和蟋蟀科聚在一起为剑瓣亚目，蚱科和蝗总科的8科组成短瓣亚目，同现用的分类系统。

Methods Twenty - four patients with CP 11 cases were treated by local excision of breast CP,10 cases were treated by mastectomy,3 cases by mastecxomy and axiUary node dissection,and 5 cases of 24 cases underwent local excision（2-3 times） for tumor recurrence post operation,who were diagnosed as adenofibroma or massive adenofibroma of the breast.

方法对24例乳腺叶状囊肉瘤患者采用局部切除11例，单侧乳房切除术10例，乳房切除并腋窝淋巴结清除3例，其中5例（20％）曾诊断为乳腺腺纤维瘤或巨纤维瘤因术后肿瘤复发而经历2～3次局部切除术。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
