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.

将10只成年Wistar大鼠分为正常对照组和缺失E1、E3基因片段且构建有Math1基因和绿色荧光蛋白报告基因的复制缺陷型腺病毒(adenovirus-Math1-enhanced green fluorescence protein， Ad-Math1-EGFP)前庭阶导入组，每组5只，实验组大鼠在右耳通过耳蜗底回前庭阶打孔的方法导入物理滴度为2.1×10^11v.p/ml的上述腺病毒5μl，对照组大鼠不做任何处理。7天后对动物进行颈髓硬膜外短声诱发电位(click-evoked potentials on the surface of the cervical dura mater， CDM-CEP)、听性脑干反应阈值检测和游泳试验，评价前庭和耳蜗功能，然后将动物处死进行组织形态学观察。

Dissociated cells were plated onto poly-d-lysine-coated coverslips and propagated in medium containing recombined Wnt3a-adenovirus. Plenty of Nurr1 were detected by RT-PCR after 3 days.

将神经干细胞分为4组，对照组、抗坏血酸诱导组、Wnt3a重组腺病毒诱导组（Wnt3a组）以及Wnt3a重组腺病毒加抗坏血酸诱导组（Wnt3a+AA组）。

Full length LMP2A cDNA was firstly incised from pGEM-T-LMP2A with EcoR Ⅰ, Sma Ⅰ digestion, and then inserted into eucaryote. expression plasmid pCIcc controlled by CMV promoter. The CMV-LMP2A-SV40 expression unit was digested by ClaI, and inserted into E1-substituted adenovirus vector pAx1cw. Then the LMP2A recombinant adenovirus vector was cotransfected into 293 cells together with EcoT22I digested Ad5-TPC.
