Objective To investigate the clinical effects of treatment of chronic pulmonary heart disease (CPHD) at acute stage with sodium ferulate and Ciwujia injection. Methods 90 cases of CPHD at acute stage were recruited into treatment group 1, treatment group 2 and control group. The control group was treated with consistent inhalation of oxygen,antibiotics, and symptomatic therapies like relieving cough, removing sputum, and stopping wheeze. The treatment group 1was treated with sodium ferulate, Ⅳ 0.2g, once daily for successive 14days, in addition to the conventional treatment. The treatment group 2 was treated with Ciwujia Injection, 100ml Ⅳ, once daily for successive 14 days. Observe the curative effect and the changes of blood gas analysis indexes (PAo2, PaCO2, SAO2) and bemorheological indexes (whole blood high-cutting viscosity, whole blood low-cutting viscosity, whole blood recovery viscosity, erythrocyte aggregation index, and HCT) before and after treatment. Result Compared with the control group, both treatment groups got improvement in blood gas analysis indexes and hemorheological indexes and curative effect, but no significant difference between the two groups (P>0.05).Conclusion both sodium ferulate and Ciwujia injection had good results in treating CPHD at acute stage, and there was no difference between the two medicines in terms of curative effects.
3.5-Azacytidine induces differentiation of bone marrow mesenchymal stem cells into myocardial cells
Chinese Journal of Tissue Engineering Research 2016;20(50):7469-7474
BACKGROUND:Bone marrow mesenchymal stem cel s can be differentiated into myocardial cel s induced by 5-azacytidine in vitro, which provides an opportunity for cel transplantation in the treatment of heart disease. OBJECTIVE:To study the induction effects of 5-azacytidine at different concentrations on the myocardial differentiation of bone marrow mesenchymal stem cel s in rats. METHODS:Passage 3 bone marrow mesechymal stem cel s were incubated with DMEM containing 0, 5, 10, 20μmol/L 5-azacytidine for 24 hours, and then the induced medium was replaced by DMEM containing 5%fetal bovine serum for subsequent 28-day culture. Afterwards, expression of cardiac troponin I was detected by immunocytochemical method. RESULTS AND CONCLUSION:Cel death occurred at 24 hours after 5-azacytidine induction, which was more obvious in the 20μmol/L group than the 5 and 10μmol/L groups. The positive expression of cardiac troponin I was significantly lower in the 5μmol/L group than the 10 and 20μmol/L groups (P<0.05), but there was no significant difference between the 10 and 20μmol/L groups (P>0.05). These experimental findings indicate that 5-azacytidine can induce the differentiation of rat bone marrow mesenchymal stem cel s into myocardial cel s in vitro, and its optimal concentration is 10μmol/L.

Purpose:To further investigate the role of the novel negative immuno-regulatory molecules in tumor evasion by testing B7-H4 e xpression on tumor tissues and spleen macrophages induced by tumor antigen of mi ce and BTLA expression on T cells of the tumor bearing mice. Methods:Via RT-PCR, we evaluated the differences in the expres sion of B7-H4 mRNA of the tumor cell lines (3LL and Renca) in vitro,tumor t issues and the expression of BTLA mRNA of the tumor bearing mice T cells;via flo w cytometry, we evaluated the differences in the expression of B7-H4 surface pr otein of the spleen macrophages from tumor bearing mice and the normal spleen ma crophages after stimulation with the tumor antigen. Moreover, via immunohistoche mistry , we also evaluated the differences in the expression of B7-H4 surface p rotein of tumor tissues. Results:Tumor cell lines (3LL and Renca) did not express the B 7-H4 mRNA in vitro.All tumor tissues or spleen macrophages in tumor bearing mice have a high expression of both B7-H4 mRNA and B7-H4 protein. Compared wi th those from normal mice, T cells from tumor bearing mice showed a higher expre ssion of BTLA. Stimulated by tumor antigen in vitro, normal mice spleen macr ophages B7-H4 expression increased significantly; while no apparent difference was found in the groups stimulated by the corresponding normal tissue antigen. Conclusions:The aberrant expression of the costimulatory molecu les, B7-H4 and its receptor BTLA, may have a regulative effect in tumor evasion immunity.
