[Effect of baicalin on expression of fibrogenic factors TGF-β1, mmp2 and timp2 in tissue of mice with pulmonary fibrosis].

To investigate the effect of baicalin extracted from Qinbai Qingfei Concentrated Pills on the expressions of TGF-β1, mmp2 and timp2 in mice with pulmonary fibrosis induced by bleomycin. The Biacore technique was used to detect the specific binding between Qinbai Qingfei Concentrated Pills and TGF-β1, and the affinity components were enriched, regenerated and recovered by Biacore fishing. Then ultra-performance liquid chromatography and quadrupole time of flight mass spectrometry(UPLC-Q-TOF-MS) were used to determine whether the monomer was baicalin.

[Effect of Dilong on expression of fibrogenic factors TGF-β1 and α-SMA in lung tissue of mice with pulmonary fibrosis].

The aim of this paper was to investigate the effect of Dilong( geosaurus) on the expressions of fibrotic factors TGF-β1 and α-SMA in bleomycin-induced pulmonary fibrosis mice. The binding ability of Dilong to fibrotic factor TGF-β1 was initially detected by Biacore technology and verified by in vivo pharmacodynamics. A total of 60 SPF C57 mice were randomly divided into 6 groups.
