Objective To compare the errors of double-center and single-center setup, and to study the role of both on reducing the rotational setup errors for the patients with esophageal carcinoma depend on rigid registration errors between online kV-cone-beam computed tomography (kV-CBCT) images and plans for CT images. Methods 20 patients with middle esophageal carcinoma received image scanning before treatment every week by using double-center setup and CBCT, and single-center setup images of 20 patients were taken from the X volume image (XVI) system. Then the images of both setup types, registration errors of CT image and rotational setup errors were compared respectively. Every patient received kV-CBCT scanning analysis before treatment every week, and 6 times in total. 240 group of kV-CBCT images from all of the patients were off-line matched with plans for CT images to calculate the errors of X-axis, Y-axis, Z-axis. Then the data of linear errors and rotational setup errors from patients were collected, aiming at putting the error data into the patients treatment program and analyzing the significances. Results The standard registration of double-center setup was as follows: T (X) (0.28 ±0.19) cm, T (Y) (0.27 ±0.19) cm, T (Z) (0.33 ±0.12) cm, R (X) (0.40 ±0.19)° , R (Y) (0.30 ±0.18)° , R (Z) (0.30 ±0.19)° . The standard registration of single-center setup was as follows:T(X) (0.32±0.20) cm, T(Y) (0.29±0.25)cm, T(Z) (0.31±0.16) cm, R(X) (2.2±0.68)°, R(Y) (0.5±0.32)°, R(Z) (2.10±0.60)°. There were statistical differences between linear errors in T(X) and rotational setup errors in R(X), R(Y) or R(Z) (P< 0.05). Conclusion Double-center position can reduce the rotational setup errors, especially in X-axis, Y-axis errors, and may provide more help for the radiation oncology departments without on-board CBCT.

Objective:To evaluate the role of hsa_circ_0025853 in hypothermia-induced reduction of oxygen-glucose deprivation and restoration (OGD/R) injury to neuroblastoma cells (SK-N-SH cells). Methods:SK-N-SH cells were cultured in vitro to the logarithmic phase and divided into 4 groups ( n=20 each) using a random number table method: control group (group C), group OGD/R, hypothermia group (group H) and hsa_circ_0025853 small interfering RNA (siRNA) plus hypothermia group (group S+ H). The cells were cultured in normal culture atmosphere in group C. The cells were subjected to OGD for 3 h followed by restoration of oxygen-glucose supply for 24 h in group OGD/R.The cells were subjected to OGD for 3 h followed by restoration of oxygen-glucose supply for 24 h at 32 ℃ in group H. The cells were transfected with siRNA at 48 h before establishing OGD/R model, and the other treatments were similar to those previously described in group H. At 24 h of restoration of oxygen-glucose, cell viability was measured by Cell Counting Kit-8, apoptosis rate were measured by flow cytometry.the expression of dynamin-related protein 1 (Drp1) mRNA and hsa_circ_0025853 was detected by quantitative real-time-polymerase chain reaction, and the expression of Drp1 protein was detected by Western blot. Results:Compared with group C, the cell viability was significantly decreased, the apoptosis rate of cells was increased, the expression of hsa_circ_0025853 was down-regulated, and the expression of Drp1 protein and mRNA was up-regulated in the other 3 groups ( P<0.05). Compared with group OGD/R, the cell viability was significantly increased, the apoptosis rate of cells was decreased, the expression of hsa_circ_0025853 was up-regulated, and the expression of Drp1 protein and mRNA was down-regulated in H and S+ H groups ( P<0.05). Compared with group H, the cell viability was significantly decreased, the apoptosis rate of cells was increased, the expression of hsa_circ_0025853 was down-regulated, and the expression of Drp1 protein and mRNA was up-regulated in group S+ H ( P<0.05). Conclusion:The mechanism by which hypothermia alleviates the OGD/R injury to SK-N-SH cells is related to the up-regulation of hsa_circ_0025853 expression, thus reducing the expression level of Drp1.

Objective:To investigate the value of nomogram based on intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) and MRI-derived radiomics for predicting recurrence after concurrent chemoradiotherapy (CCRT) in patients with locally advanced cervical cancer (LACC).Methods:Clinical data of 111 patients with ⅠB-ⅣA cervical cancer who underwent CCRT at Anhui Provincial Hospital from December 2014 to December 2019 and were continuously followed up were retrospectively analyzed. Pre-treatment IVIM-DWI parameters (ADC, D, D * and f) and pre- and post-treatment 3D texture parameters (from axial T 2WI) of the primary lesions were measured. Least absolute shrinkage and selection operator (LASSO) algorithm and multivariate logistic regression analysis were used to filter texture features and calculate radiomics score (Rad-score). A Cox regression model was used to analyze independent risk factors for recurrence after CCRT in patients with LACC and construct a nomogram. Results:External beam radiotherapy dose, f value , pre-treatment Rad-score and post-treatment Rad-score ( HR=0.204, 3.253, 2.544, 7.576) were the independent prognostic factors for recurrence after CCRT in cervical cancer patients and jointly formed the nomogram. The area under curve (AUC) of the nomogram for predicting 1-, 3- and 5-year disease-free survival (DFS) was 0.895, 0.888 and 0.916, with internal validation C-indexes of 0.859, 0.903 and 0.867, respectively. The decision curves analysis showed that the nomogram has a higher net clinical benefit compared to other models, and the clinical impact curves further visualized its predictive accuracy. Conclusions:The nomogam based on IVIM-DWI and radiomics has high clinical value in predicting recurrence after CCRT in patients with LACC, providing reference for prognostic assessment and individualized treatment of cervical cancer patients.
