Objective To discuss the value of clinical radiomic nomogram(CRN)and deep convolutional neural network(DCNN)in distinguishing atypical pulmonary hamartoma(APH)from atypical lung adenocarcinoma(ALA).Methods A total of 307 patients were retrospectively recruited from two institutions.Patients in institu-tion 1 were randomly divided into the training(n=184:APH=97,ALA=87)and internal validation sets(n=79:APH=41,ALA=38)in a ratio of 7∶3,and patients in institution 2 were assigned as the external validation set(n=44:APH=23,ALA=21).A CRN model and a DCNN model were established,respectively,and the performances of two models were compared by delong test and receiver operating characteristic(ROC)curves.A human-machine competition was conducted to evaluate the value of AI in the Lung-RADS classification.Results The areas under the curve(AUCs)of DCNN model were higher than those of CRN model in the training,internal and external validation sets(0.983 vs 0.968,0.973 vs 0.953,and 0.942 vs 0.932,respectively),however,the differences were not statistically significant(p=0.23,0.31 and 0.34,respectively).With a radiologist-AI com-petition experiment,AI tended to downgrade more Lung-RADS categories in APH and affirm more Lung-RADS cat-egories in ALA than radiologists.Conclusion Both DCNN and CRN have higher value in distinguishing APH from ALA,with the former performing better.AI is superior to radiologists in evaluating the Lung-RADS classification of pulmonary nodules.

Objective To analyze and explore the health response capability construction in the long-term recovery phase of nuclear or radiological emergencies. Methods By evaluating China’s participation in an international nuclear emergency exercise organized by Organization for Economic Co-operation and Development’s Nuclear Energy Agency, and considering the relevant guidelines published by international organizations such as the International Atomic Energy Agency, the sections that need to be strengthened in the health response during the long-term recovery phase of nuclear or radiological emergencies were analyzed. The related issues such as health monitoring and medical follow-up were explored. Results The tasks in the long-term recovery phase mainly include monitoring the affected population and information management, medical follow-up, and psychological assistance. In response to potential nuclear or radiological emergencies, 22 nuclear emergency medical rescue bases have been established in China, with a geographical distribution that includes key regions. Relevant institutions have basic capabilities of health response to nuclear or radiological emergencies. However, the exercise shows that strategy and capacity construction in long-term recovery phase are weak points in health response to nuclear or radiological emergencies. China should further strengthen strategies in major public protection actions and information management of affected populations in nuclear or radiological emergencies. Conclusion It is recommended to develop standard operating procedures for major public protection actions, long-term health monitoring and evaluation of affected populations, medical follow-up, and psychological assistance in the future. A unified health registration system for affected populations in nuclear or radiological emergencies should be established to further enhance China’s health response capabilities during the long-term recovery phase of nuclear or radiological emergencies.
