摘要: 目的 观察乙醛激活的大鼠肝星状细胞(HSCs)结缔组织生长因子(CTGF)、纤维连接蛋白(FN)和整合素的表达变化,以及中药肝复康对它们表达的影响。方法 制备肝复康含药血清,体外培养HSC-T6细胞,用乙醛及肝复康含药血清干预HSCs,采用RT-PCR法检测HSCs中CTGF、FN、整合素α5、整合素β1和α-平滑肌肌动蛋白(α-SMA)mRNA的相对光密度值。结果 乙醛刺激后HSC-T6细胞CTGF、FN、整合素α5、整合素β1和α-SMA mRNA水平分别为(1.06±0.02)、(1.28±0.23)、(2.13±0.09)、(1.57±0.50)和(2.84±0.14),与空白对照组细胞[分别为(0.46±0.05)、(0.40±0.09)、(0.37±0.10)、(0.19±0.03)和(0.18±0.03)]相比,均显著升高(P<0.01),而肝复康干预能显著降低它们的水平[分别为(0.59±0.02)、(0.71±0.15)、(1.55±0.04)、(0.92±0.22)和(1.99±0.10),P<0.01]。结论 肝复康干预HSCs活化可能与抑制CTGF、FN、整合素α5、整合素β1和α-SMA水平有关。

Abstract: Objective To observe the changes of connective tissue growth factor (CTGF),fibronectin (FN),and integrin mRNA levels in a herbal medicine-intervened HSC-T6 cells in vitro.Methods Sera containing Gan-fu-kang,a herbal medicine compound,was prepared from rats. HSC-T6 cells were cultured in vitro,and the HSCs activated by acetaldehyde were incubated with sera containing Gan-fu-kang. RT-PCR was used to detect the mRNA of CTGF,FN,integrin-α5,integrin-β1 and α-smooth muscle actin (α-SMA). Result The mRNA levels of CTGF,FN,integrin-α5,integrin-β1,and α-SMA in the HSCs stimulated by acetaldehyde were(1.06±0.02),(1.28±0.23),(2.13±0.09)(1.57±0.50) and(2.84±0.14),respectively,significantly higher than those in the control cells [(0.46±0.05),(0.40±0.09),(0.37±0.10),(0.19±0.03) and (0.18±0.03),P<0.01],and they were down-regulated after incubated with sera containing Gan-fu-kang [(0.59±0.02),(0.71±0.15),(1.55±0.04),(0.92±0.22) and(1.99±0.10),respectively,P<0.01].Conclusion The effect of Gan-fu-kang is related to the inhibition of CTGF,FN,integrin α5, integrin-β1 and α-SMA in activated HSCs.
