Methods: The amount of 3H-TdR (3H-thymidine) admixed in cultured rat VSMC was measured and mitogen-activated protein kinase (MAPK) activity and lipid peroxidation end product malondialdehyde (MDA) content of the VSMC were assayed. Results: 1×10?9, 1×10?8, 1×10?7 mol/L LPA in a concentration dependent manner, induced the amount of 3H-TdR admixed, MAP kinase activity, and MDA content of the cultured rat VSMC to increase. However, 5%, 10%, and 15% Yangxueqingnao serum preincubation resulted in a decrease of 23.0%, 42.0%, and 52.0% (P<0.01) respectively in the amount of 3H-TdR admixed, a decline in VSMC MAP kinase activity of 13.9% (P<0.05), 29.6% (P<0.01), and 48.9% (P<0.01) respectively, and also, a decrease in MDA content of VSMC of 19.4%, 24.7%, and 43.2% (P<0.01) respectively, in the 1×10?7 mol/L LPA-treated VSMC. Conclusions: LPA activates the proliferation and lipid peroxidation of VSMC in a concentration dependent manner. The LPA-induced VSMC proliferation is related to the activity of MAP kinases, enzymes involved in an intracellular signalling pathway. The results of the present study showed that Yangxueqingnao particles can effectively inhibit LPA-induced VSMC proliferation, MAP kinase activation, and reduce lipid peroxidative lesion.展开更多

Methods: PIF models were established by blemycinA5-induced in rats. They were treated by Qidan granule and Hydrocortisone respectively. The pathological changes and collagen protein disposition were observed, and the expression of TGF-β, TNF-α proteins were measured by immunohistochemical technique. Results: The pulmonary alveolitis and fibrosis were alleviated remarkably in Qidan granule group compared with those in the model control group and hydrocortisone group (P<0.01). The expression of TGF-β and TNF-α protein were higher in Qidan granule group than those in normal group ,and were significantly less than those in the model control group and in hydrocortisone group (P<0.01). Conclusion: Qidan granule would ameliorate the pulmonary alveolitis and fibrosis. TGF-β and TNF-α might play an important role in the development of alveolitis and fibrosis in rats.展开更多
