四种中药对骨愈合过程中相关基因表达的影响

目的:探索中药水蛭、海螵蛸、阿胶、骨碎补在骨折愈合过程中的干预作用,了解它们各自的调节靶点,探索建构其基因组学的途径。方法:通过在大鼠胫骨打孔的方法建立单因素干扰模型,并将300只大鼠随机分为正常组、模型组和给药组(分别用4种中药给药),每组50只,分别在实验的第4、7、14、21、28天不同时间点采用原位杂交方法对各类mRNA的变化进行动态观察,分析骨愈合过程中Ⅰ、Ⅱ、Ⅲ型前胶原mRNA、转化生长因子TGF-β1mRNA、骨形态发生蛋白BMP-2mRNA以及血管内皮生长因子VEGF-mRNA的表达情况。结果:不同中药对不同基因的作用不同,作用的时间点不同,作用强度也存在差异。其中海螵蛸在骨折早期对Ⅰ、Ⅲ型前胶原mRNA、VEGF-mRNA、BMP-2mRNA的表达升高,后期Ⅱ、Ⅲ型前胶原mRNA表达水平下降,VEGF-mRNA、TGF-β1mRNA表达量维持于较高水平;骨碎补组较模型组在BMP-2mRNA、TGF-β1mRNA、Ⅰ型前胶原mRNA的表达上差异有显著性统计意义;阿胶对骨愈合早、中期Ⅰ、Ⅱ、Ⅲ型前胶原mRNA和TGF-β1mRNA的表达与模型组比较差异存在显著性统计意义;水蛭对VEGF-mRNA的表达具有一定的促进作用。结论:海螵蛸、水蛭对血管形成有促进作用,阿胶、骨碎补和海螵蛸对骨折软骨形成早期具有促进骨诱导的作用,并对成骨细胞的增殖及合成活性有较大影响。     

~(125)Ⅰ眼镜蛇毒及抗眼镜蛇毒血清在小白鼠体内分布的比较观察

用氯胺-T法125I标记眼镜蛇毒示踪液及抗眼镜蛇毒血清。小白鼠分二组，用125I-眼镜蛇毒、125I-抗眼镜蛇毒血清分别给小白鼠尾静脉注射，于注射后的不同时间测定血、颈部肌肉、肝、肺、肾、心等脏器放射性分布。结果发现：125I-眼镜蛇毒在肌肉及肝、肺等器官中于注射后2小时过高峰，在肾脏中浓度高，在脑未见放射性分布，抗眼镜蛇毒血清与眼镜蛇毒分布相似但在肌肉及肺脏有更高的分布。证明抗眼镜蛇毒血清能跟踪分布眼镜蛇毒。     

中国汉译西医学著作在日本的流传和影响

调查了十九世纪汉译西洋医学著作在日本的出版和流传情况，有９种汉译西洋医学著作曾在日本出版，其中６种曾多次再版，７种有和训或和译本，这些著作曾在日本医生中广泛流传，促进了西洋医学在日本的传播和普及，对日本医学从传统医学向现代医学的转变起过一定的作用。本文还分析了汉译西洋医学著作能够在日本广泛流传的原因     

A Chinese adolescent girl with Fechtner-like syndrome

We describe a 15-y-old girl with Fechtner-like syndrome, who is the first Chinese reported to have this rare syndrome. She presented with left homonymous hemianopia and neuroimaging revealed haemorrhage in both parietal and occipital lobes. Peripheral blood smear showed macrothrombocytopenia and intracytoplasmic inclusion bodies inside leucocytes. Thrombocytopenia and proteinuria responded to intravenous immunoglobulin and pulsed methylprednisolone. This case illustrates that life-threatening haemorrhage can occur in patients with Fechtner syndrome. Although there was no effective treatment reported in the literature, high dose steroid and immunoglobulin seemed to be useful in our patient. Our patient also had nephritic-nephrotic syndrome with renal insufficiency, which is unusual in adolescent female patients.     

黑龙江省地产中药抗菌作用的实验研究

为开发我省地产中药资源，作者对地产中草药进行了较为全面系统的研究，本文仅报道我省几种地产中草药抗菌作用的实验研究，将抗菌效果好的艾叶、泽兰、大活、木贼、苦参和与之对照的紫丁香的抗菌作用进行对比，结果表明，紫丁香的抗菌作用效果好，毒副作用小。另外所试中３药因抗菌作用不如叶、泽兰、大活、木贼、苦参、紫丁香具有较好抗菌作用。是很有研究价值的中药。     

Inter- and intra-individual variability of non-invasive tear break-up time in Hong Kong Chinese

Non-invasive tear break-up time (NITBUT) has been proposed as a measure of tear film integrity which is superior to the more commonly used tear break-up time (TBUT), since it does not alter the volume or the physicochemical properties of the tear layer by the addition of fluorescein. We measured NITBUT by measuring the time taken for distortions or discontinuities to appear in the reflected image of a grid pattern which covered about 80 per cent of the corneal surface. NITBUT measures were made 100 times on seven Hong Kong Chinese subjects with up to 20 consecutive measures being made on a single day. We also measured NITBUT on one occasion on an unselected population of 52 Hong Kong Chinese subjects. NITBUT shows a skewed distribution in all subjects, with many shorter values and some extremely long values. There are statistically significant variations in NITBUT from day to day, and from subject to subject. The group of 52 subjects also had a skewed NITBUT distribution with many short values and some very long values. The arithmetic mean does not adequately represent NITBUT data, either for individual subjects or for this group of subjects. As many as five to eight measures may be necessary to gain a stable estimate of the NITBUT and stability of the measure is improved if extreme values are omitted. We recommend the use of nonparametric statistics to compare NITBUT values from day to day in or between subjects.     

近年中医药治疗中风后遗症进展

中医药对中风后遗症治疗方法主要包括：①辨证分型治疗；②主方加减治疗，具体包括补气活血方、滋补肝肾方和健脾益气方；③虫类药治疗；④单味药治疗。但是，今后应把中医药、针灸、推拿等方法综合应用于临床，以便取得更好的疗效。同时应加强临床科研设计和实验研究，使中医药治疗中风后遗症更上一个层次。

取消统编教材,开拓学术空间--关于取消中医院校统编教材之我见

中医院校的教材采用统编方式已不适合现代科技信息发展的需要，相反，取消中医统编教材，给院校和教师更多的主动权，有利于中医学新知识、新信息的传播，有利于教师参与教学研究，发挥独创精神，有利于学问的兼收并容和中医学术的发展，也有利于学生增强对专业的认识和信心，并有利于素质教育的开展。
