Na-K-Exchanging ATPase is a universal cell membrane protein in higher eukaryotic cells which mediates the anti-concentration gradient exchange of intracellular Na+ for extracellular K+. It plays essential metabolic roles such as maintaining sodium and potassium ion gradients across the plasma membrane. The targeted sequences were amplified by PCR to determine the genome structure of the hithertofore unsequenced portion of the alpha 1 subunit of the human Na-KExchanging ATPase gene which encodes 80-130 aa of its extracellular domain using two different templates, human genomic DNA and a human muscle cDNA library. The PCR products were analyzed by restriction endonuclease digestion and then cloned into a plasmid vector for chemiluminescence sequencing and further analysis.

Na-K-Exchanging ATPase是一种普遍存在于高等生物体内的细胞膜蛋白，主要参与介导K+和Na+在细胞内外之间的逆浓度梯度的转运，并维持一定细胞内外的离子梯度，我们采用聚合酶链式反应方法分别以人基因组DNA及cDNA文库为模板对人Na-K-Exchanging ATPaseα1亚单位基因胞外区约80-130位氨基酸编码序列进行扩增，限制性酶切分析扩增产物，并进行荧光测序，对测序结果进行同源性分析及剪接位点的搜索并对得到的核苷酸序列进行进一步的分析，发现人基因组DNA和cDNA经过扩增后分别得到833bp和195bp两种不同大小的片段Fg，Fc。

The large area of grey tone to create a background that covers the whole painting and the thin color with an intense vividness of water-color paintings brings the paintings to life; the use of small-area color as flamboyant as fluorescence in the creation of the subject gives the paintings a fable touch; both implements and sets against the other perfectly well. Each implements and sets against the other with perfection.

Methods Ten mature Wistar rats were divided into normal control group (5 rats) and adenovirus (E1, E3-Deleted and carried math1 and enhanced green fluorescent protein report gene, Ad-Math1-EGFP) scala vestibuli transfer group (5 rats). Right ears of the Ad-Math1-EGFP transfering group rats were deliveried 5μl Ad-Math1-EGFP (physical tite 2.1×10^11v.p./ml) into cochleas through the way of drilling scala vestibuli of cochlear basal turn. As a control, the normal group received nothing to inner ear. In order to estimate functional condition of vestibule and cochlea, the click-evoked potentials on the surface of the cervical dura mater, auditory brain stem response and swimming time were recorded in all rats at 7 days after treatment, and then histologic and morphologic observation were carried out after animals were sacrificed. Results All animals' morphologic observation showed that inner ear hair cells were normal after transfer.
