基于血络理论的黄褐斑辨识分析

黄褐斑是一种慢性、获得性面部色素增加性皮肤病,“血瘀”是黄褐斑形成的主要原因。面部为十二经脉气血汇集之处,面部的荣华离不开气血的滋养及经络的运行通畅。经脉作为经络系统主干在内运行气血津液,络脉作为其分支横向沟通内外,运行气血津液,贯通经脉。皮肤血络理论的形成是建立在对皮肤络脉认识基础上,注重皮肤血络、气络、津络相辅相成,认为皮肤气络、津络均依附于皮肤血络,强调皮肤血络是关键枢纽。基于皮肤血络理论对黄褐斑的病因病机和诊疗思路进行探讨,认为痰瘀凝络是其核心病机;外邪伤络、内伤七情、体质易感是其发病原因;病机本虚标实,本为“气络虚”和“血络虚”,实为“血络痰瘀”;中医药治疗可内调外治,内调应审证求因、通补兼施,外治可经皮给药、直达病所,且注重花-藤-虫-胶药物的使用。

AECOPD的气络、血络理论

结合王琦教授提出的"肺络微型癥瘕与气道重构的相关性"的理论,我们认为COPD急性加重期的病位主要在肺的络脉,且有气络和偏于血络病变之分受损气络偏于功能改变,而血络偏于器质性的改变,特别是肺的微血管系统的形质变化,病机属于痰、气、瘀交阻及肺络微型癥瘕邪阻于络脉,病性属本虚标实。并希望以此为契机,探讨AECOPD的中医发病机制,为临床治疗提供新的思路。

皮肤血络理论探析

络脉学说起源于《黄帝内经》,治法萌芽于《伤寒杂病论》,病证论治体系于《临证指南医案》初步形成,如今在许多学科中得到广泛应用。络脉学说在皮肤病领域的应用仍有待发展。皮肤络脉分为气络、津络、血络。血络主内守,气络主卫外,津络主充润。皮肤血络为皮肤腠理所属的有形络道,是脏腑病变传化到皮肤的必由之路。血络调和,则气络条达,津络畅通,皮肤络脉病变以皮肤血络为关键枢纽,也是皮肤病变的前提。邪气伏藏于皮肤血络,是慢性皮肤病的病机特点。笔者总结了络脉学说的渊源和现代发展,提出皮肤血络理论,并就其内涵、理论意义和临床价值进行了阐述,旨在推进络脉学说在皮肤病领域的应用。

Study of blood sugar concentration based on serum UV absorption spectra＊

UV absorption spectrum and neural network theory was used for the analysis of blood sugar concentration. Experimental investigation shows that absorption spectrum has the following characteristics in the wave band of 200-300 nm： （1） The absorption spectrum is of complex shape, there is more absorption peak in UV-band, it shows that there is a complex absorption phenomenon in blood group macromolecules; （2） The curve shapes of absorption spectra are similar to different samples ,the reason is that the spectrum is synthesis of some group macromolecules absorption spectrum; （3） There is a degree of displacement of absorption peak to different samples; （4） There is no significant correlation between absorbance and blood sugar concentration at 278 nm, but random. Based on the wave band of 280 nm to 300 nm, a neural network model was built to determine the blood sugar concentration.
