Results ① The percentage of positive TPOAb and TGAb were 91.4% and 74.4%, respectively in all the AIT patients. 47.6% of the patients had TSH levels within normal range (0.3～5mu/L).② All of the slides had different grades of lymphocytic infiltration. 49.3% had germinal center, 32.8% had Askanazy cells, 26.9% had plasma cells, 22.4% had colloid, and 9% had multinuclear giant cells.③ Lymphocytic infiltration was divided into four degrees. The levels of TSH and TPOAb increased significantly in the extremely heavy lymphocytic infiltration grade than in the others (P.05). There was no relationship between serologic markers and other cytopathologic features.

结果 ①82例患者中TPOAb、TGAb的阳性率分别为91.4%和74.4%，约有半数(47.6%)TSH值位于正常值范围内(0.3～5mu/L)；②所有患者细胞病理学均存在淋巴细胞不同程度的浸润，49.3%可见生发中心，32.8%可见嗜酸性变细胞，26.9%可见浆细胞，22.4%可见胶质，9%可见多核巨细胞；③将淋巴细胞浸润程度分级，分别与TSH、TPOAb及TGAb进行相关性分析，发现仅淋巴细胞极重度浸润者其血清TSH、TPOAb水平较其他组显著升高(P.05)，其他细胞病理学改变与血清学指标之间未发现显著相关性。

In this paper, we reviewed the advances in this area with some important grasses such as Lolium L. Dactylis L., Festuca L., Feymus Hochst, and Elymus L., in which included the screening of molecular markers and construction of molecular genetic maps, gene clone, and transgenetic grasses et al.

By the cooperation of 8-MOP/UVA, the photoaging-characteristic biological markers of the dermic fibroblasts in vivo and in intro were changed as follows:① with a permanent switch of mitotic to stably postmitotic phentypes, fibroblasts displayed growth suppression and morphological changes of cell senescence;② increasing expression of SA-β-galactosidase;③ increasing expression of p16 protein;④ continuous up-regulation of mRNA of MMP-1 and MMP-3, while the protein of TIMP-1 was only slightly induced;⑤ high levels of the 4977bp deleted mtDNA accumulated in dermis and cultured fibroblasts, and large accumulation of a A→C base transversion of 414 position of 〓 of human mtDNA control region for replication of cultured fibroblasts also.

2.8-MOP/UVA作用下，体内外真皮成纤维细胞生物学特性出现具有光老化特征性的改变：①细胞由具有分裂活性的分裂表型转化为不具有分裂能力的分裂后表型，形态学出现细胞衰老的相应改变；②SA-β-Gal表达增加；③p16蛋白表达增加；④MMP-1、MMP-3 mRNA持续表达而TIMP蛋白表达仅被轻微诱导；⑤mtDNA 4977bp缺失大量累积，培养成纤维细胞mtDNA复制控制区〓片段414碱基迅速出现大量A→C的点突变。

Safety parameters including blood lipids, inflammatory and diabetogenic markers remained within the normal range.

包括血脂，炎症和致糖尿病标志物在内的安全参数均在正常范围。

In this study, analyses of yield combining ability, SSR molecular markers was made to study in 198 combinations which come from different strains in the basic S1 66 plants of 39007 and 39002 groups and three types of tests in Incomplete Diallel Cross Experiments.

以39002和39007群体不同基本株的S166个单株及其与3个测验种按不完全双列杂交试验设计组配198个组合为供试材料，对单株产量的配合力和供试群体S1的多态位点数，基因杂合度等参数进行了分析，并利用遗传相似系数进行聚类。

Regarding to QTL analysis with single locus, segregation distortion would not affect QTL mapping, but regarding to analysis of digenic interactions for epistasis, the fewer distortion markers and larger size population would be needed.

对于单位点的QTL分析而言，偏分离标记一般不会影响QTL定位的位置和效应；对于两位点的上位性分析而言，则要求较少的偏分离标记和较大的群体。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
