ABSTRACT Fuzheng Huayu recipe (FZHY) is an effective traditional Chinese medicine for the treatment of liver fibrosis.
This review summarizes the main mechanism and the substantial basis of FZHY recipe in the treatment of hepatic fibrosis, including its effects on the function of multiple types of cells in liver and extracellular matrix metabolism, the blood components and active substances and their characteristics of tissue distribution and metabolism.

肝纤维化的中医基本病机为“正虚血瘀”,正虚主要表现为气阴两虚,血瘀则主要表现为瘀血阻络。扶正化瘀方(制剂为扶正化瘀胶囊/片)立足于中医“血瘀阻络、正气亏虚”的基本病机,由丹参、冬虫夏草、桃仁、松花粉、绞股蓝、五味子等6味中药组成。可改善肝炎后肝硬化患者肝功能、调整异常免疫功能和降低血清肝纤维化标志物水平等,对乙肝肝纤维化的组织学逆转率达52%,且肝组织炎症活动度也有明显改善[1]。抗丙肝肝纤维化美国多中心Ⅱ期临床试验也显示出该药良好作用。对其主要作用机制与效应物质,近年也有较多研究,归纳于下。
1 扶正化瘀方影响肝纤维化的作用机制
1.1 抑制肝星状细胞活化
肝星状细胞(hepatic stellate cells,HSC)的活化是肝纤维化的中心环节,其激活途径包括肝细胞损伤后形成脂质过氧化产物、胞外基质(extracellular matrix,ECM)改变与肝库普弗细胞等激活后分泌细胞因子的旁分泌刺激,以及星状细胞活化后自身分泌细胞因子以刺激与维持细胞活化的自分泌作用,细胞因子以转化生长因子-b1(transforming growth factor β1,TGF-b1)与血小板衍生生长因子bb(platelet derived growth factor-bb,PDGF-bb)作用尤为显著。……
