人Uroplakin Ⅱ启动子用于靶向性基因治疗膀胱癌的实验研究

目的探讨利用人UroplakinⅡ(hUPⅡ)启动子进行靶向性基因治疗膀胱癌的可能性。方法将hUPⅡ启动子和肿瘤坏死因子-α(TNF-α)克隆到腺病毒载体Ad5中,构建重组体pAd-hUPⅡ-TNF。转染细胞293后产生复制缺陷型的重组腺病毒,感染膀胱癌细胞系BIU-87,检测TNF-α对BIU-87细胞体外生物学行为及体内成瘤性的影响。结果成功构建pAd-hUPⅡ-TNF重组腺病毒载体,转染细胞293获得复制缺陷型重组腺病毒。BIU-87细胞经重组腺病毒感染后可产生高浓度的TNF-α,并降低BIU-87的生长速度。感染腺病毒的BIU-87培养液可抑制L929细胞的生长。裸鼠原位膀胱肿瘤动物模型实验结果表明膀胱灌注重组腺病毒48h后,裸鼠尿液含高浓度的TNF-α,4周后腺病毒组膀胱重量和体积明显低于对照组(P<0.01)。结论hUPⅡ启动子TNF-α为治疗基因的重组腺病毒可特异性使膀胱癌细胞系BIU-87产生高浓度的TNF-α,并降低BIU-87和L929细胞的生长速度。重组腺病毒可使裸鼠尿内含高浓度的TNF-α,并可抑制裸鼠原位膀胱肿瘤动物模型膀胱癌细胞的成瘤性。

Distribution of alpha 2-adrenergic receptor mRNAs in the rat CNS.

alpha 2-Adrenergic receptors (ARs) are involved in central nervous system (CNS) control of blood pressure. It is now known that there are three human genes that encode subtypes of alpha 2-ARs, but little is known regarding the distribution of these subtypes throughout the CNS. The availability of receptor clones allows the mapping of mRNAs encoding the individual alpha 2-AR subtypes in the CNS. In this communication, we report that there are three, closely related rat alpha 2-AR genes. We have developed subtype-specific hybridization probes from each of these genes and have used these reagents to measure alpha 2-AR subtype mRNA accumulation in extracts of discrete regions of the rat CNS. We found that mRNAs encoding the alpha 2A-AR and alpha 2C-AR subtypes are distributed widely, but unevenly, throughout the rat CNS. The A subtype is prominent in the midbrain, brainstem, spinal cord, pituitary and diencephalon while the C subtype predominates in basal ganglia and cerebellum. The cortex, olfactory bulb and hippocampus contain roughly equal amounts of the alpha 2A- and alpha 2C-AR mRNAs. A third subtype's (alpha 2B-AR) mRNA is far less abundant in brain tissues, and is only found in the diencephalon.

Influence of serum protein on polycarbonate-based copolymer micelles as a delivery system for a hydrophobic anti-cancer agent.

A new micelle system formed from methoxy (polyethylene glycol)-b-poly (5-benzyloxy-trimethylene carbonate; MePEG-b-PBTMC 5000-b-4800) was investigated as a delivery system for the hydrophobic anti-cancer agent, ellipticine. The ellipticine was loaded into the MePEG-b-PBTMC micelles with a loading efficiency of 95% using a high-pressure extrusion technique. The ellipticine-loaded micelles have a spherical morphology and an average diameter of 96 nm. The anti-cancer activity of ellipticine was confirmed to be retained following formulation in the MePEG-b-PBTMC micelles. The extent of protein adsorption to the MePEG-b-PBTMC micelles was investigated by transmission electron microscopy, dynamic light scattering and gel filtration chromatography. Overall, the amount of protein both loosely and tightly associated with the micelles was found to be minimal and insignificant. The partitioning properties of ellipticine between an aqueous medium containing protein and the MePEG-b-PBTMC micelles were examined over a range of protein concentrations. Under physiologically relevant conditions, it was found that 61% of the drug remained within the micelle fraction while 39% was in the protein-containing aqueous phase. In addition, the in vitro drug release profile of ellipticine from the micelles was fit using a modified Higuchi model and found to be accelerated in the presence of protein. These studies demonstrate that although there are no significant interactions between micelle and protein, the properties of the micelle as a delivery vehicle may be strongly influenced by protein-drug interactions.

发挥远程教育优势推进医学继续教育发展

《教育部关于加强高校网络教育学院管理提高教学质量的若干意见》中强调指出：高校网络教育学院要以在职人员的继续教育为主，要充分发挥网络教育的优势，为在职人员更新知识、增强技能、不断学习、不断提高提供良好的服务。然而，要使医学院校在开展继续教育中发挥更大的作用，推进医学继续教育的发展，远程教育不仅是解决这一问题的有效途径，而且将成为开展医学继续教育的强大动力。
