Objective To evaluate the characteristic of left ventricular rotation and twist in healthy adults using ultrasonic velocity vector imaging(VVI),and to discuss its biomechanical mechanism. Methods In 70 healthy adults, the rotational characteristic of left ventricular subendocardium and subepicardium at 3 differently standard shot-axis levels and 18 differently myocardial segments, and the torsional characteristic of left ventricular wall were evaluated via ultrasonic VVI. The maximum rotation angle(Rmax)at different sites of left ventricular wall and the maximum twist angle(Tmax)between left ventricular subendocardium and subepicardium in a completely cardiac cycle were compared respectively. Correlation tests were performed between left ventricular Tmax and the Rmax at different short-axis levels of left ventricular wall.Results ①To be compared with other myocardial segments, Rmax was smallest at antero-septal or anterior wall of the same left ventricular short-axis level(P>0.05).②The mainly rotational directions of the basal leveI and the apical level of left ventricular wall in a completely cardiac cycle were adverse.To be compared with basal or apical level of left ventricular wall,Rmax was smallest at papillary muscle level(P<0.05).and there was no statistical significance in Rmax between basal and apical level.There was positive colinearity between left ventricular Tmax and the Rmax of basal or apical level (P<0.01),but zero correlation was found between the Tmax and the Rmax of papillary muscle level.③Rmax of left ventricular subendocardium was bigger than that of subepicardium(P<0.01).Tmax of left ventricular subendocardium was bigger than that of subepicardium[(11.44±4.82)°vs(7.05±3.90)±,P<0.01].Conclusions Twist of left ventricular wall in healthy adults appeared the torsional characteristic of thin-wall cylinder.Elucidation of the biomechanical mechanism of cardiac twist is promising if basing on the principle of biomechanics.

Background Corneal neovascularization (CNV) is one of the causes of corneal blindness.Studies showed that ADP-ribosylation factor (ARF) can regulate the growth of tumor cells,and inhibiting ARF will decrease angiogenesis.However,whether ARF antagonist plays an action on CNV is unclear.Objective The aim of this study was to explore the effect and mechanism of ARF inhibitor on alkali-burn induced CNV.Methods Sixty clean male BABL/c mice aged 7-8 weeks were divided into PBS group and ARF antagonist group according to randomized number table.CNV models were induced by NaOH burn method in all the mice.ARF at the concentration of 0.5 g/L(0.5 ml) was intraperitoneally injected 3 times per week for 1 week followed the induction of CNV in the ARF antagonist group,and 0.5 ml PBS was used in the PBS group.CNV was examined 2,4,7,14 days after injection by the slit lamp microscope and the CNV related area in the cornea was calculated.Betore modeling(0 day) and 4,7,14 days after modeling,real-time PCR and Western blot were used to analyze the expressions of ARF mRNA and protein in the corneas.Forteen days after modeling,the expression of the CD31 in the CNV was detected using immnofluorescence of corneal whole mount;the expression of vascular endothelial growth factor(VEGF) in the cornea was assayed by Western blot.Cellular wound scratch test was employed to evaluate the effects of ARF antagonist on proliferation and migration of human retinal vascular endothelial cells (RECs).All animal experiments were done in accordance with the ARVO Statement for the Use of Animals in Ophthalmic and Vision Research and Guideline for the Care and Use of Laboratory Animals on the the Soochow University Animal Care Committee.Results ARF mRNA and protein were expressed in the mice corneas in both the PBS group and the ARF antagonist group at various time points.The expression of ARF mRNA in mice corneas was enhanced with the lapse of the time (Ftime =65.17,P =0.00),but no significant difference was found among the groups (Fsroup =1.98,P=0.18).There was also significant difference in the expression of ARF protein in mice corneas at different time points in the ARF antagonist group (F =10.77,P =0.00).The related CNV area was 0.45±0.05 in the ARF antagonist group,and that in the PBS group was 0.72±0.11,with significant difference between them (t =-3.87,P ＜ 0.05).The green fluorescence area of C D31 expression in the cornea was smaller in the ARF antagonist group than that of the PBS group.Expression level of VEGF in the ARF antagonist group was 1.20±0.21,and that in the PBS group was 2.47±0.33,showing a significant difference (t =-5.62,P ＜ 0.05).As the increase of ARF antagonist concentration,the inhibiting rate of cell proliferation was reinforced among 10,100 and 1 000 μg/L ARF antagonist groups (F=8.47,P =0.02).Twenty-four hours after scratch test,the migrating distance of human RECs was (5.46±1.32) μm and (5.04±1.68) μm in the 100 μg/L and 1 000 μg/L ARF antagonist groups,respectively,which were shorter than (8.49± 1.18) μm of the PBS group (t=-2.94,-2.91,both at P＜0.05).Conclusions ARF inhibitor can reduce CNV by down-regulating the expression of VEGF in alkaline burn cornea and inhibiting the proliferation and migration of vascular endothelial cells.
