Radiomic of enhanced CT for identification of benign and borderline serous tumors of ovary / 中国介入影像与治疗学

Objective: To establish radiomic model based on enhanced CT, and to observe the value of the model for distinguishing benign and borderline serous tumors of ovary. Methods: Data of CT imaging of 49 patients with ovary serous cystadenoma (SC) and 31 patients with serous borderline tumors (SBT) confirmed by pathology were retrospectively analyzed. AK software was used by 2 radiologists to delineate ROI of the tumors, and radiomic parameters were extracted. Then multiple Logistic regression was applied to identify optimal radiomic features and construct the prediction model. ROC curve was used to analyze the diagnostic efficacy of radiomic parameters and model on ovarian SC and SBT. Results: A total of 396 image radiomics parameters were extracted, and 5 feature parameters were obtained after dimensionality reduction, namely Percentile10, Percentile15, SA, LRHGLEa90, o1 and LRHGLEa90, o7, respectively. The results of reproducibility analysis of 2 radiologists had good consistency (all intraclass correlation coefficient> 0.75). Radscore prediction model was constructed with the above 5 characteristic parameters, and the AUC, sensitivity and specificity of Radscore model for differentiating ovarian SC and SBT in the training set was 0.90, 0.91 and 0.79, while in the testing set was 0.86, 0.90 and 0.73, respectively. Conclusion: Radiomic model based on enhanced CT can be used for identifying SC and SBT of ovary.

The influence of trunk control training on motor function and the ability in the activities of daily living of patients with cerebral palsy / 中华物理医学与康复杂志

Objective To observe the influence of trunk control training on motor function and the ability of cerebral palsy (CP) patients in the activities of daily living (ADL).Methods Forty patients with CP were randomly divided into a treatment group (n =20) and a control group (n =20).Both groups were treated with routine rehabilitation,while the treatment group also received trunk control training.All patients were assessed with function ambulation category (FAC) classification,time to walk 10 m,the Berg balance scale (BBS),and the modified Barthel index (MBI) at the beginning and eight weeks later.Results Before the intervention there was no significant difference between the two groups in terms of any of the assessments.Eight weeks later,all the assessment scores were significantly better in the treatment group than in the control group.Conclusion Trunk control training can significantly improve motor function and the ADL ability of patients with CP.
