In this work , 1,8-octodiol, the starting material, reacted with 40% hydrobromic acid to produce 8-bromooctan-1-ol, with the catalytic action of PPTs, its hydroxyl group was protected by 2,3-dihydropyran. Then it coupled with 1-heptaalkyne, by means of P-2 nickel as catalyst, stereoselectivity catalysis hydrogenated, with the catalytic action of acid to take off extremital 2, 3-dihydropyran which protected hydroxy group, then used PCC to oxidize alcohol into corresponding aldehyde.

That GER cells which are likely hair cell progenitors could be cultured in vitro and generate stereociliary bundle-like structure when forced to express Hath1 suggests that the misexpression of Hath1 probably can induce the predifferentiation of pure hair cell progenitors into hair cells in vitro.
GER细胞作为毛细胞前体细胞可以实现体外原代培养,在Hath1基因重表达情况下,部分细胞的表面可见不成熟的纤毛样结构,提示Hath1基因也许可以诱导离体培养下的纯的毛细胞前体细胞向毛细胞的初步分化。

The normally brominated Baylis-Hillman adducts were formed as the major product at low temperature. While at room temperature or heating, the α,γand β,β-dibrominated compounds were formed as the major products using 3-butyn-2-one and methyl propiolate or propynenitrile as substrate, respectively.
贫电子炔类化合物的Baylis-Hillman反应的研究在这部分工作中我们发现在用TiBr〓或BBr〓为Lewis酸催化贫电子炔类化合物和芳香醛的Baylis-Hillman反应时,温度对反应的影响很大:当反应在低温下进行时,通常生成的是正常的β-溴代的Baylis-Hillman反应产物;而在室温或加热条件下反应,以丁炔酮为底物时,主要生成的是α,γ-二溴化合物,而以丙炔酸甲酯及丙炔腈为底物时,主要生成的是β,β-二溴化合物。

①Rat MSC and VSMC were cultured and identified, respectively. MSC were labeled with DAPI firstly, and then co-cultivated with VSMC. The changes of morphology and ultrastructure of co-cultured cells were observed. Immunfluorescence analysis was performed by using monoclonal antibodies against specific antigen.②We established the regulatable system in two steps: a stable MSC line expressing rtTA has been constructed and characterized firstly by transfected with pUHD 17-1hyg and then selected by hygromycin B; in a second step, this line was used for trandfer the AT2R gene to MSC to get the well establishing double stable MSC lines;③The expression of AT2R regulated by doxycycline was evaluated by western blot;④The MSCs were transduced into rat carotid arteries with regulatable AT2R gene after the establishment of rat carotid balloon injury restenosis model. The intimal/medial area ratio were measured by digital analysis system.
