摘要
目的 探讨扶正化瘀方对肝星状细胞（HSC）分泌血管内皮生长因子（VEGF）的干预以及对自分泌激活途径的影响。 方法 大鼠灌以扶正化瘀方，制备含药血清；用含药血清添加法观察扶正化瘀方对活化HSC分泌VEGF的影响；以含药血清活化HSC条件培养液温育原代HSC，观察药物对HSC增殖与I型胶原分泌的作用。结果 扶正化瘀方对活化的HSC分泌VEGF的增加有抑制作用；活化的HSC可明显促进静止HSC的增殖与I型胶原的分泌；扶正化瘀方可明显抑制这一促进作用。 结论 扶正化瘀方对HSC的自分泌激活途径有抑制作用，抑制活化的HSC分泌VEGF可能是其作用机制之一。
Objective To investigate the intervention of Fuzhenghuayu decoction on autocrine activation of hepatic stellate cell. Methods The drug serum containing Fuzhenghuayu decoction was collected from the normal rats, and cultured with activated hepatic stellate cells (HSC) in vitro. The conditional medium from the drug serum treated HSC was collected, and added to primarily cultured quiescent HSC. The primary cell proliferation was assayed by MTT colorometric test, and the contents of type I collagen and vasular endothelial growth factor (VEGF) in the medium were assayed with ELISA. Results The coditional medium from activated HSC could stimulate the proliferation and type I collagen secretion in the quiescent HSC. The drug serum inhibited this stimulating action and VEGF secretion from activated HSC. Conclusion Fuzhenghuayu decoction has inhibitory action on the autocrine-activating pathway of HSC. The mechanism may be associated with inhibiting the secretion of VEGF by activated HSC. [
