Sodium Ferulate(SF)is sodium salt of ferulic acid.Experimental studies showed that SF can reduce ischemical reperfusion injury of brain,heart,and liver.Clinically,SF was widely used in cardio-cerebrovascular diseases and immune system disorder.In the article,the experimental studies on SF preventing ischemical reperfusion injury of tissues were reviewed.

Objective To demonstrate the possibility when discriminating between severe and nonsevere tricuspid regurgitation by E-wave velocity in tricuspid flow.Methods The peak velocity of the tricuspid inflow E-wave was measured in 107 patients,who were divided into mild group(n =39),moderate group(n =42)and severe group(n =26)according to the degree of tricuspid regurgitation(TR).Results Peak E-wave velocity of mild group,moderate group and severe group was (48.6 ±13.8)cm/s,(47.4 ±11.7)cm/s,and (78.3 ±26.1)cm/s, respectively.Mean E-wave velocity of mild group and moderate group were similar,which were lower than that of severe group (P <0.01).A peak E-wave velocity of over 62 cm/s had a sensitivity of 71% and specificity of 92% for the detection of severe TR.Conclusion Increased peak tricuspid E-wave velocity is associated with severe TR and thus can be used as a simple measure of TR grade.
