The Sprouty protein can inhibit cel proliferation and induce apoptosis by specific interventions in the signaling pathways of tumor cells, such as receptor tyrosine kinase signaling pathway. The Sprouty protein, which is often associated with abnormal cell proliferation and transformation, is down-regulated in many tumors, stimulating the initiation and progression of tumors. The Sprouty protein exhibits potential for developing effective treatment against cancer. This paper reviews research progress on Sprouty protein in tumor.

ObjectiveTo compare the difference effects on the proximal stomach in rapid(intake rate 100 mL/min) and slow(intake rate 15 mL/min) LNLT.Methods Forty healthy subjects received both the rapid and slow LNLTs.The caloric density of the nutrient was 1 kcal/mL. The TVDRI and MVDRI were recorded,and the corresponding TVPS and MVPS were measured by B-ultrasound.Results(1) There were positive correlation was identified between TVDRI and TVPS,and between MVDRI and MVPS in both slow and rapid LNLTs.(2) TVDRI and MVPS in slow LNLT were significantly smaller than those in rapid LNLT,but MVDRI was significantly larger in slow LNLT than that in rapid LNLT.(3) TVDRI was much closer to TVPS in slow LNLT than those in rapid LNLT.But MVDRI was much closer to MVPS in rapid LNLT than those in slow LNLT.Conclusion Both slow and rapid LNLTs could be used to evaluate the accommodation to a meal and visceral sensitivity of the proximal stomach.The visceral sensitivity is related to the accommodation function.TVDRI of slow LNLT is more sensitive in estimating the visceral sensitivity of the proximal stomach;MVDRI of rapid LNLT is more accurate in estimating the accommodation of the proximal stomach.

Objective To assess the effects of intraventricular conduction abnormality on left ventricular function in dilated cardiomyopathy. Methods The study composed of 3 groups,16 patients of dilated cardiomyopathy (DCM) without wide QRS complexes, 16 patients of DCM with complete left bundle branch block(CLBBB),and 16 age-matched healthy individuals,all showing sinus rhythm and being complicated with mitral regurgitation. Pre-ejection contraction time(PET), left ventricular ejection time(LVET), left ventricular filling time(LVFT), myocardial performance index(MPI), mitral regurgitation time(MRT), stroke volume(SV) were recorded with pulsed or continuous-wave Doppler. Pulse tissue Doppler imagining(TDI) was performed to measure the time dispersity of electromechanical motion of left ventricular in systole and diastole on the atrial-ventricular annulus with mapping techniques. Results Time dispersity of electromechanical motion of adjacent left ventricular segments in systole[((77.9)?(13.6))ms vs ((52.1)?(13.2))ms vs ((28.3)?(7.2))ms, P

Objective To evaluate atrial stunning and the recovery of atrial function after successful cardioversion in the patients with atrial fibrillation by utilizing tissue Doppler imaging(TDI) and M-mode echocardiography in atria-ventricular annulus motion, together with pulsed Doppler echocardiography and apexcardiogram. Methods Thirty-four patients with atrial fibrillation received ultrasound examinations in 1 hour,1 day,1 week and 1 month after successful cardioversion. The results were compared with those of 20 age-matched healthy individuals. From the echocardiography apical 4-chamber views, the atrial mechnical activities in the mitral and tricuspid annulus were recorded using two-dimensional echocardiography guided M-mode and TDI. Furthermore, pulsed Doppler transmitral and transtricuspid inflow velocity and apexcardiogram were also recorded. Atrial stunning means the lack of atrial mechanical function after atrial electrical activity was recovered with successful cardioversion. Results Left and right atrial functions after cardioversion were both inferior to those of the healthy ones,but improved with time,up to 1 week right arial function turned basically to normal and 1 month left one recovered to normal.The incidence of atrial stunning in left and right atrium accounted for (20.6)% and (14.7)% respectively at 1 hour after successful cardioversion, (11.76)% and (14.7)% at 1 day, (6.5)% and (3.2)% at 1 week. Conclusions Both left and right atrial functions are lower than the normal after cardioversion,and atrial stunning happens in both atria.Left and right atria recover to normal respectively in 1 month and 1 week.
