PartⅡ: Analysis of the paraffin embeded tissue slides [obtained from trail and control group at pre-treatment (d0) and post-operation (d15±1 days) ] and frozen section slides (from 4 typicalcases: 1 of IAC group, the other sBRM group at d5, d7 and d10), by H-E stain, monoclonal antibodies (CD3/CD4/CD8/CD68/CD57) marking, SP-DAP or APAAP-AEC stain, and TUNEL in situ apoptotic cell DNA fragments fluorescin labeling.

二。组织病理学研究：对上述两组病人治疗前后原发灶肿瘤组织蜡块分别作H-E和CD3、CD68表型免疫组化染色；并对其中四例典型病人的疗中间断连续活检新鲜组织作H-E染色，CD3、CD4、CD8和CD57表型免疫组化染色和凋亡细胞DNA断片TUNEL法荧光标记检测。

Absorption spectra indicate that there is little or no interaction between chromphores in the ground state. However, the fluorescence emission of oxadiazole and triphenylamine moieties are almost quenched, which shows that in the excited ground state there exists very effective intermolecular singlet-singlet energy transfer.

研究发现，这些多发色团化合物在基态发色团之间没有作用或作用很小，而其中恶二唑和三苯基胺单元的荧光被严重的猝灭，这说明在激发态下，萘酰亚胺发色团与恶二唑、三苯胺功能团之间发生了分子内单线态－单线态能量转移。

Here we introduced oxadiazole moiety to theside-chain of Ph-PPV to enhance the electron transport properties. The luminescenceefficiency and luminescence brightness (1.33cd/A, 9400 cd/m~2) of the Ph-PPV withside oxadiazole moiety are much higher than non-oxadiazole Ph-PPV (0.70 cd/A,2300 cd/m~2), and these polymers emitted green light which unaffected by theintroduction of oxadiazole moiety. Anthracene has a rigidity and planar structure which shows high photoluminescenceand thermo-stability.

结果表明，以十烷氧基作为间隔基使噁二唑单元键接在苯基取代PPV的侧链，所得材料制备的电致发光器件的效率和亮度(1.33cd／A，9400 cd／m~2)明显高于不含噁二唑单元的苯基取代PPV(0.70 cd／A，2300 cd／m~2)，噁二唑单元的引入并不影响材料的发光光色，膜状态下的荧光发射光谱和电致发光光谱均呈绿光发射。

Furthermore, preliminary work also performed to examine whether PI3K/AKT signal transduction pathway was activated in the process of refractory leukemia development. Materials and methods An immortalized human bone marrow stromal cell line, HS-5, was introduced to establish a bi-phase culture system for the cultivation of B-lineage precursor leukemia cells. ELISA and RT-PCR were used to investigate the expression of VEGF and its receptors in the leukemia cell lines and primary childhood leukemia cells in different treated groups. Flow cytometory method and immunofluorescent staining were employed to examine the apoptosis signals both in the VP16 treated and untreated leukemia cells. Western blot was utilized to explore the PI3K/AKT activated status in the drug induced or uninduced leukemia cells and lymphocytes from healthy donors.
