Methods: 90 patients who received radiotherapy for thoracic and abdominal tumors in the department of oncology of our hospital from September 2019 to September 2021 were screened and divided into 3 groups according to the differences of clinical treatment with different postural fixation schemes: groups A, B and C. Among them, group A chose the vacuum pad fixed position, and group B chose the body membrane fixation position, and group C chose the vacuum pad combined membrane fixation position. The number of patients in each group was 30 cases, and then compared the changes of the body position mobility, movement error and other indicators in each group. Results: regarding the mobility rate of patients, the mobility rate of group C was 6.00%, which was much lower than 24.00% and 34.00% of groups A and B, and the difference was prominent, with statistical advantages, P0.05;for the mobility error of patients, for example, groups A, B and C were (1.21±0.24) mm, (3.77±0.54) mm, and (4.23±0.88) mm, respectively, and the differences were significant, with statistical advantages, P0.05;in terms of positional measurement deviation, group C was much smaller than groups A and B, and the difference was prominent, with a statistical advantage, P0.05. Conclusions: for patients with thoracic and abdominal tumors, in the process of receiving radiation therapy, the choice of vacuum pad combined with body membrane fixation position for treatment has significant advantages. Compared with the single implementation of vacuum pad and body membrane fixation position, it can greatly reduce the movement error, swing measurement deviation, and also reduce the mobility rate as much as possible, so this is a postural fixation solution worthy of wide application.展开更多
By applying iterative technique,we obtain the existence of positive solutions for a singular Riemann-Stieltjes integral boundary value problem in the case that f（t,u） is non-increasing respect to u.
