Abstract:
Objective:To investigate the effects of Yisui Shengxue Decoction on the regulation of Notch signaling pathway on bone marrow hematopoiesis in mice with aplastic anemia(AA).Methods:A total of 60 CByB6F1 mice were randomly divided into blank group,model group,positive control cyclosporine(CsA)group,low-dose(YSSX-L)group and high-dose(YSSX-H)group of Chinese herbal compound Yisui Shengxue Decoction,with 12 mice in each group.Except for the blank group,the mice in each group were given 5 Gy X-ray irradiation combined with tail vein infusion of lymphocytes to establish the immune-mediated AA mouse model.The low and high dose groups were given 8.6 and 17.2 g/(kg?d)of Yisui Shengxue Decoction by gavage,the model group and the blank group were given equal volume of saline by gavage,and the positive control group was given 25 mg/(kg?d)of cyclosporine by ga-vage for 14 days.The mice were tested for white blood cell count(WBC),red blood cell count(RBC),hemoglobin(Hb),platelet count(PLT)and bone marrow nucleated cell count in peripheral blood,bone marrow pathological changes and the levels of IFN-γ,IL-4 and IL-5 in peripheral serum,and T-lymphocyte transcription factors T-bet,GATA3,RORγt,FOXP3 mRNA and protein in spleen tissues,as well as the expression levels of Notch signaling pathway-related genes and protein in spleen tissues.Results:Compared with the blank group,the peripheral blood WBC,RBC,Hb,PLT,bone marrow nucleated cell count,expressions of serum IL-4,IL-5 and spleen tissue GATA3,FOXP3 mRNA and protein were significantly lower in the model group(P<0.01),and the expressions of serum IFN-γ,spleen tissue T-bet,RORγt mRNA and protein,and Notch1,Jagged1,DLL4 mRNA and protein were significantly in-creased(P<0.05).Compared with the model group,peripheral blood WBC,RBC,Hb,PLT,bone marrow nucleated cell count,ex-pressions of serum IL-4,IL-5 and spleen tissue GATA3,FOXP3 mRNA and protein were significantly higher in each intervention group(P<0.05),and the expression of serum IFN-γ and spleen tissue T-bet,RORγt mRNA and protein as well as Notch1,Jagged1,DLL4 mRNA and protein were significantly reduced(P<0.05).Conclusion:Yisui Shengxue Decoction can improve bone marrow he-matopoietic function and regulate immune disorders in AA mice,and its mechanism of action may be related to the regulation of Notch signaling pathway.
