Studies have shown that IL-24 is the only cytokine capable of inhibiting tumor growth and neovascularization as well as stimulating immune system. IL-24 exerts its inhibition effects through pathways independent of p53, Rb, p16 and other tumor suppressor genes and has no effect on normal cells. IL-24 has emerged as a hot topic in cancer therapy research.

Objective:Our purpose was to establish an ideal chronic pressure-afterload heart failure rat model which has the transition from cardiac hypertrophy to heart failure. Methods: Chronic pressure-afterload heart failure rat model was induced by gradually constricting the ascending aorta of young rats. Young rats were randomly divided into 2 groups: the constricted and sham-operated groups. Clinical manifestation, tail-cuff blood pressure, organ weight, and hemodynamic data were observed at various time after operation. Results: The overall survival rate was 87%. Tail-cuff pressure began to increase in 4 weeks after operation. Left ventricular hypertrophy appeared in 12 weeks and heart failure in 5 months. Conclusion:It's a practical and reproducible model of cardiac hypertrophy that progresses to chronic heart failure.

Objective To assess the regional left ventricular (LV) rotation motion in the patients with rheumatic mitral stenosis (MS) with velocity vector imaging (VVI).Methods This study included 38 patients with isolated MS (mild,moderate and severe) and 55 healthy control subjects.Short-axis parasternal views at the basal and apical level of LV were taken.Peak value of rotation angle and rotation velocity,as well as time to peak value were measured by VVI workplace offline respectively.Results ①In the healthy control subjects LV rotates clockwisely at the base and counterclockwisely at the apex,the same as the patients with MS.② In th patients with MS,rotaion angle and rotation velocity were significantly reduced at the apical level(P ＜0.001),rotation velocity were significantly reduced at some segments of basal level (anterior,lateral,septal) (P ＜ 0.05).③Compared with the healthy control,the difference of time to peak roation angle between base and apex was significantly longer in patients with MS (P ＜0.05).④ There were no significant differences among mild,moderate and severe MS (P ＞0.05).Conclusions The patients with MS may suffer from systolic dysfunctin even in the early stage identified by the alteration of LV rotation motion,which is independent of the hemodynamic severity of MS.
