Aim To observe the changes on the expression of ?-SMA in rats with adriamycin-induced nephrothy and intervention of Valsartan. Methods The model group were made by unilateral nephrectomy with twice-adriamycin injections by caudal vein. Immunohistochemical method, flow cytometry and pathologic image analysis were used to observe the expression of ?-SMA, FN and LN in rats. Results The expression of ?-SMA was positive in the model group. Rates of positive cell and protein semi-quantitative analysis were more higher than the sham group(P

Objective:To compare the volatile chemical constituents from the shell and kernel of Caesalpinia minax Hance.Methods:The volatile chemical compositions of Caesalpinia minax Hance were obtained by organic solvent-wet distillation and were analyzed by GC-MS equipped with a elastic quartz capillary column HP-5MS 5%Phenyl Methyl Siloxane(30m?0.25mm?0.25?m).The constituents were identified by their mass spectra.The relative percentage of the volatile constituents was calculated from the GC peak areas.Results:One hundred and fifteen kinds of chemical constituents in the shell of Caesalpinia minax Hance were separated and sixty-three of them,which accounts for 54.7%of total volatile constituents, were characterized.There are five kinds whose relative contents were more than 2.0%.One hundred and two kinds of chemical constituents in the kernel of Caesalpinia minax Hance were separated and fifty-one of them,which accounts for 50.0%,were characterized.There are seven kinds whose relative contents were more than 2.0%.Form the shell and kernel of Caesalpinia minax Hance there were forty kinds of chemical constituents the same.The most relative contents were Limonene(5.31%,shell)and 1-Hexanol(12.94%,kernel).Conclusion:This paper reports,for the first time,the comparison of volatile constituents from shell and kernel of Caesalpinia minax Hance.It is helpful for controlling the quality and further researching of Caesalpinia minax Hance.

Objective To investigate the feasible clinical teaching method for ICU specialty nurses to improve teaching quality.Methods Using new mode:teaching together but practicing with different teachers.Results Through clinical practice,19 specialty nurses have improved their theories,operational skills and clinical thinking abilities.Conlusions ICU specialty nurses can acquire systems training through the new teaching mode.
