)组及空白组作用于A549细胞，用细胞增殖与毒性检测法(MTS)检测这些有效成分对A549细胞的毒性作用，以筛选出丹参有效成分的安全浓度。在安全浓度范围下，再将细胞分为空白组，模型组，丹酚酸A组，丹酚酸B组，丹参素组及丹参酮Ⅱ

组，用MTS法检测丹参有效成分对转化生长因子-

(TGF-

)诱导的A549细胞的增殖抑制作用；酶联免疫吸附测定(ELISA)检测丹参有效成分对纤连蛋白(FN)，I型胶原(COL-Ⅰ)表达的影响。综合以上结果，筛选出抑制作用较好的丹参有效成分，用蛋白免疫印迹法(Western blot)检测对细胞E-钙粘(E-Cad)蛋白表达的影响。

0.01)。ELISA结果显示，与空白组比较，模型组细胞FN，COL-Ⅰ的表达显著增加(

0.01)；与模型组比较，丹酚酸A 20 μmol·L

-1

，丹酚酸B 40，80 μmol·L

-1

对FN，COL-Ⅰ的表达有明显抑制作用(

0.05)；Western blot结果显示，与空白组比较，模型组细胞E-Cad的表达显著降低(

0.01)；与模型组比较，丹酚酸A 20 μmol·L

-1

，丹酚酸B 80 μmol·L

-1

0.01)。

结论：

丹酚酸A，丹酚酸B对TGF-

诱导的上皮间质转化具有抑制作用，可能是治疗肺纤维化的有效成分。

Abstract

Objective:

To screen out the effective components of Salvia miltiorrhiza by establishing an in vitro model of pulmonary epithelial mesenchymal transformation.

Method:

Different concentrations of salvianolic acid A (10

160 μmol·L

-1

)

salvianolic acid B (10

160 μmol·L

-1

)

tanshinol (10

160 μmol·L

-1

)

tanshinoneⅡ

(10

160 μmol·L

-1

) and the blank group were applied to A549 cell

cell proliferation and cytotoxicity assay (MTS) were used to detect the proliferation effect of menthol on A549 cells.After screening the safe concentration of the active ingredients of salvia miltiorrhiza by MTS

cells were divided into blank group

model group

salvianolic acid A group

salvianolic acid B group

tanshinol group and tanshinoneⅡ

.Then

the inhibitory effect of the active ingredients of salvia miltiorrhiza on the proliferation of A549 cells induced by TGF-

was detected by MTS. Enzyme linked immunosorbent assay (ELISA) method to detect salvia miltiorrhiza effective component of fiber protein(FN)

collagen type I (COL-Ⅰ) expression. Based on the above results

the active components of salvia miltiorrhiza

which have best inhibition were screened out

and their effects on the expression of E-calcium-viscosity (E-Cad) protein were detected by Western blot.

Result:

Compared with blank group

salvianolic acid A 40 μmol·L

-1

salvianolic acid B 160 μmol·L

-1

tanshinol 160 μmol·L

-1

had toxic effects on A549 cells (

0.05). In the non-toxic concentration range

compared with the model group

salvianolic acid A 10

20 μmol·L

-1

salvianolic acid B 80 μmol·L

-1

showed inhibition effect after 24 h culture (

0.05). After 72 h culture

salvianolic acid A 5

20 μmol·L

-1

salvianolic acid B 40

80 μmol·L

-1

inhibition effect was very significant (

0.01). ELISA results showed that with the blank group

model group cells the expression of FN and COL-Ⅰ increased significantly (

0.01). Compare with model group

salvianolic acid A 20 μmol·L

-1

salvianolic acid B 80 μmol·L

-1

inhibited FN and COL-Ⅰ(

0.05). Western blot results showed that salicylic acid A and salicylic acid B had protective effects on E-Cad (

0.01).

Conclusion:

Salvianolic acid A and salvianolic acid B have inhibitory effects on epithelial mesenchymal transformation by TGF-

which may be the main effective components of salvianolic acid in the treatment of pulmonary fibrosis.
