Automatic diagnosis of eyelid tumors based on target localization / 中国医学物理学杂志

Eyelid tumor is a serious eye disease that leads to vision loss or even blindness.The similarity between benign and malignant characteristics makes it difficult for ophthalmologists lacking clinical experience to distinguish between them.To address the problem,a method(ResNet101_CBAM)based on two-stage target localization using fully convolutional one-stage object detection(FCOS)and residual network incorporating a dual attention mechanism is proposed to realize the automatic diagnosis of benign and malignant eyelid tumors.FCOS is used to automatically localize the overall contour of the orbit,removing the background and surrounding noise,and then finely localize the tumor lesion inside the orbit.The obtained lesion region is input into ResNet101_CBAM for the automatic diagnosis of benign and malignant eyelid tumors.The experimental results show that the average precision of the target localization algorithm for tumor lesion is 0.821,and that compared with ResNet101,ResNet101_CBAM improves the sensitivity and accuracy in eyelid tumor classification by 4.7%and 3.0%,respectively,indicating that the proposed model has superior performances in the automatic diagnosis of benign and malignant eyelid tumors.

Research on similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy / 中国实用护理杂志

Objective To study the similarities and differences of information needs between cancer patients treated with radiotherapy and chemotherapy, analyze the causes for cancer patients' different choices, and provide reasonable and disease-related information for cancer patients. Methods A total of 102 and 119 cancer patients treated with radiotherapy and chemotherapy relatively were asked to complete the questionnaire (IPQCP+2) and two questions about the total information capacity and content requirements. Results Two groups had different needs of therapeutic information and treatment in IPQCP. Cancer patients treated with chemotherapy needed more widely-ranged information than patients underwent radio-therapy. Conclusions Most of cancer patients treated with radiotherapy and chemotherapy need to be informed of disease-related information, among which the content of therapeutic information and total information is relative to the treatment. Nurses should provide disease-related medical information based on their different needs, as to improve the life quality of cancer patients.
