目的: 研究复方六月青(CLYQ)对肝星状细胞(HSC)增殖和细胞外基质(ECM)的影响。 方法: 采用四甲基噻唑蓝(MTT)法检测CLYQ对HSC的毒性。采用酶联免疫吸附实验(ELISA)法检测HSC上清液羟脯氨酸(Hyp)、透明质酸(HA)和金属蛋白酶组织抑制因子-1(TIMP-1)。 结果: CLYQ体外对HSC的 TC50=6.191 g ·L-1
TC0=3.504 g ·L-1
CLYQ抑制HSC的增殖。CLYQ各剂量组均可显著降低HSC细胞上清液Hyp
HA
TIMP-1含量(P<0.05
P<0.01)
呈现量效反应关系。 结论: CLYQ通过抑制HSC的增殖
从而使ECM合成减少
肝纤维化减轻。
Abstract
Objective: To study the influence of CLYQ on proliferation and extracellular matrix(ECM) of hepatic stellate cells(HSC). Method: Cytotoxicity caused by CLYQ was detected by MTT assay. The contents of hydroxyproline (Hyp)
hyaluronic acid (HA) and tissue inhibitor of metalloproteinase-1 (TIMP-1) in HSC cell supernate were detected by enzyme linked immunoabsorbent assay (ELISA). Result: TC50 is 6.191 g ·L-1
and TC0 is 3.504 g ·L-1. CLYQ could inhibit the proliferation of HSC. The various concentration group of CLYQ could degrade significantly the contents of Hyp
HA and TIMP-1 in cell supernate (P<0.05
P<0.01)
presenting the dose-effect relationship. Conclusion: CLYQ can inhibit the proliferation of HSC
so that reducing the synthesis of ECM and hepatic fibrosis.
