摘要
目的:用蛋白质组学技术考察四物汤对血虚证患者血清蛋白的影响,在分子水平上探讨四物汤治疗血虚证的作用机制。方法:收集正常、血虚证患者和四物汤用药患者的血清,用二向电泳、图像分析、质谱鉴定等蛋白质组学技术测定四物汤对血虚证患者血清中有影响的蛋白质。结果:蛋白质组学研究发现,血虚证患者血清与正常相比有15个蛋白质的水平发生改变,其中有11个上调和4个下调,四物汤可使这些改变的蛋白质水平有所恢复。胶内酶切提取蛋白进行质谱鉴定,其中血虚证患者血清与正常相比升高的蛋白质有结合珠蛋白,聚集素,补体C4B,GTP结合蛋白2,与正常相比降低的蛋白质有转甲状腺素蛋白,血红蛋白β。血虚证患者服用四物汤后可降低结合珠蛋白,聚集素,补体C4B,GTP结合蛋白2,升高转甲状腺素蛋白,血红蛋白β。结论:四物汤可以通过增强免疫,减轻基因损伤,增加血红蛋白等途径治疗血虚证。
Objective： To research the effects of Siwu tang on serum protein of blood deficiency using proteomic technique and further explore its potential molecular mechanism to cure blood deficiency. Method： The sera of normal, blood deficiency and cured group were collected. Proteomic protocol involving the high resolution two-dimensional polyacryamide gel electrophoresis, the computer- assisted image analysis, and the mass spectrometry was used to detect regulated protein by Siwu tang. Result： Compared with normal group, there were 15 proteins changed, in which 11 increased and 4 decreased expressed proteins in sera could be recovered by Siwu tang. The up-regulated proteins involved haptoglobin, clusterin, complement component CAB and GTP binding protein 2, while the down-regulated proteins involved transthyretin and heamoglobinβ. Conclusion： Siwu tang could regulate serum protein, which include immunology, apoptosis, DNA injury repair, and blood ingredients. This might be the mechanism of Siwu tang to cure blood deficiency.
