Figure 5 The decrease of long axis radial strain firstly appeared in the posterior wall, while the decrease of the long axis longitudinal strain firstly appeared in the apical segment in the 5-fluorouracil + bevacizumab group. (n=10) A: The long axis longitudinal strain of poet. base. B: The long axis longitudinal strain of poet. mild. C: The long axis longitudinal strain of poet. apex. D: The long axis longitudinal strain of ant. base. E: The long axis longitudinal strain of ant. mild. F: The long axis longitudinal strain of ant. apex. G: The long axis radial strain of poet. base. H: The long axis radial strain of poet. mild. I: The long axis radial strain of poet. apex. J: The long axis radial strain of ant. base. K: The long axis radial strain of poet. apex. L: The long axis radial strain of poet. apex. 5-FU + BEV group: 5-fluorouracil + bevacizumab group. *: P <0.05.
