Thrombotic diseases in different forms become a great threat to human health. Such anti-platelet aggregation drugs as aspirin and clopidogrel are common drugs in clinic. However, along with the appearance of resistance and side effects of western anti-platelet aggregation drugs, anti-platelet aggregation traditional Chinese medicines promoting blood circulation to remove blood stasis have gradually become an important study orientation. Platelet is one of major participant in thrombosis, and plays an important role as a bioactive material in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, mainly involving two aspects--the evaluation for the anti-platelet aggregation activity of traditional Chinese medicines and the screening of their active components. This paper summarized the applications of platelets in studies on traditional Chinese medicines promoting blood circulation to remove blood stasis, so as to provide basis for further studies.

ObjectiveTo observe the lung injury of rats caused by PM2.5 induced imbalance of TH17/Treg immune system and the intervention effect of two different TCM treatments.Methods Wistar male rats were randomly divided into normal group, model group, TCM-treated group1 and TCM-treated group 2. PM2.5-induced lung injury model was established by airway instillation. Model group was given normal saline for gavage. TCM- treated group 1 and 2 were given Yupingfeng Powder and Guomin Decoction combined with Zhisou Powder for gavage. The pathological changes of bronchial and lung tissues, the contents of IL-8, IL-10, IL-17, NE, and MUC5AC in serum and BALF were compared, and the expressions of Foxp3 and IL-17 in lung tissue of each group were analyzed.Results Compared with normal group, the contents of IL-8, IL-17, NE and MUC5AC in serum and BALF of model group increased significantly, while IL-10 decreased significantly (P<0.05,P<0.01); the expression of IL-17 increased significantly and the expression of Foxp3 decreased significantly in lung tissue (P<0.01). Compared with model group, the contents of IL-8, IL-17, and NE decreased in TCM-treated group 1 and 2, while the content of BALF IL-10 increased significantly (P<0.05). The content of IL-10 in serum increased significantly in TCM-treated group 2 (P<0.05); the protein expression of IL-17 of lung issue decreased significantly, and the protein expression of Foxp3 increased significantly (P<0.01). The pathological changes were improved significantly.Conclusion PM2.5 can induce lung injury caused by the imbalance of TH17/Treg. Both two treatments can significantly improve the lung injury induced by PM2.5 and the imbalance of TH17/Tregs immune system.

AIM: To explore the effects of cholestoral and mevalonate synthesis inhibitor lovastatin (LOV) on the proliferation of NB4 cells and elucidate the mechanisms. METHODS: Cell proliferation was analyzed by MTT assay;the expression of H, K, N- ras oncogenes in NB4 cells at different time point after LOV treatment were determined by semi-quantitative RT-PCR. Both total p21 Ras protein and p21 Ras protein on the cellular membrane were examined by flow cytometry. RESULTS:①LOV inhibited the proliferation of NB4 cells. ②All three kinds of ras were expressed in NB4 cells. ③LOV caused no increase in H, K, N- ras mRNA level. Amount of total p21 Ras protein did not change as the time varied. Concomitantly,p21 Ras protein localized on the cellular membrane decreased. CONCLUSION:LOV inhibits the proliferation of NB4 cells. Targeting HMG-CoA reductase, LOV blocks the isoprenylation of p21 Ras protein which affects its anchorage on the cellular membrane. No change in the H, K, N- ras mRNA and total p21 Ras protein expression is detected.
