The 87 HE images and labeled images of periapical cysts were divided into a training set (72 images) and a test set (15 images), which were used in the training model and test model, respectively. Finally, the target level index F1 score, pixel level index Dice coefficient and receiver operating characteristic (ROC) curve were used to evaluate the ability of the U-net model to recognize periapical cyst epithelium.@*Results @# The F1 score of the U-net network model for recognizing periapical cyst epithelium was 0.75, and the Dice index and the areas under the ROC curve were 0.685 and 0.878, respectively.@*Conclusion@#The U-net network model constructed by artificial intelligence has a good segmentation result in identifying periapical cyst epithelium, which can be preliminarily applied in the pathological diagnosis of periapical cysts and is expected to be gradually popularized in clinical practice after further verification with large samples.
ABSTRACT
@#With widespread popularization, the radiological diagnosis and treatment technology has played an increasingly important role in clinical practice. The tertiary general hospital is generally featured as multiple types of radioisotope and radiation equipment, wide involvement of departments and persons, and many ways of use and potential harms of the radiological diagnosis and treatment technology. Radiation protection has become a content that cannot be ignored in hospital management. This article analyzes the radiation protection management structure of the tertiary general hospital - Guangdong Provincial People’s Hospital. The hospital radiation protection management is gradually improved by clarifying the main leading department, refining duties and responsibilities, strengthening multi-departmental communication and cooperation, and sorting out key connection links. A closed loop of refined management is formed through digging and correcting problems and continuously improving the management level and work efficiency. Valid qualifications are ensured to be obtained in time by radiation workers, radioactive drugs, equipment, and the venues to guarantee the radiation safety of radiation workers and patients and to further promote the construction of the Safe Hospital.
ABSTRACT
Objective To analyze and master the allocation and distribution of radiological diagnosis and treatment resources in Nanjing, China, and to provide a basis for the health administrative departments to reasonably plan and allocate the radiological diagnosis and treatment resources in the whole city. Methods A general survey using the questionnaire on general information of radiological diagnosis and treatment institutions was conducted to investigate the amount and type of radiological diagnosis and treatment equipment and number of radiation workers in medical institutions in the whole city. Results There were totally 347 radiological diagnosis and treatment institutions at all levels involving 3999 radiation workers and 1342 sets of radiological diagnosis and treatment equipment in Nanjing. In urban radiological diagnosis and treatment institutions, there were 2798 (69.99%) radiation workers and 842 (62.74%) sets of radiological diagnosis and treatment equipment, more than those in the suburbs (1201 and 500 sets). There were 27 (7.78%) tertiary radiological diagnosis and treatment institutions, with 629 (46.87%) sets of radiological diagnosis and treatment equipment, which was more than those in the primary (287), secondary (189), and ungraded (237) medical institutions. There were 158 sets of radiological diagnosis and treatment equipment and 470 radiation workers per million people in Nanjing. Conclusion The distribution of radiological diagnosis and treatment equipment in Nanjing is uneven between urban and suburban areas and between various levels of medical institutions. The government and health administrative departments need to enhance the macroscopic readjustment and control, thus promoting the reasonable allocation of medical resources.

ABSTRACT
Objective To analyze the distribution status and agglomeration degree of radiological diagnosis and treatment resources in Beijing, and provide references for rationally coordinating the allocation of radiological diagnosis and treatment resources, formulating resource allocation policies, and promoting the stable development and efficient use of radiological diagnosis and treatment resources. Methods Based on the medical radiation protection monitoring data of Beijing medical and health institutions from 2019 to 2020, the current situation of radiological diagnosis and treatment resources is described by the number of radiological diagnosis and treatment resources, the average service volume, and the resource composition, and the distribution of radiological diagnosis and treatment resources in Beijing is evaluated with the aid of the agglomeration degree. Results The number of radiological diagnostic equipment, the number of service personnel, and the number of radiological workers engaged in third-level hospitals is the largest; for the number of service personnel for each type of single equipment, third-level hospitals account for a larger proportion, and radiotherapy and nuclear medicine services are concentrated in third-level hospitals. Human resource pressure and equipment service pressure are relatively high in third-level hospitals. First-level hospitals mainly undertake radiological diagnosis services. There is little difference in the amount of radiological diagnosis services per capita between second-level hospitals and third-level hospitals. Nuclear medicine and radiotherapy in third-level hospitals per capita service volume is significantly higher than that insecond-level hospitals. Radiological diagnosis and radiotherapy resources are concentrated in urban areas to a large extent. Conclusion There are obvious differences in the utilization of radiological diagnosis and treatment resources in different levels of hospitals. There is a significant concentration of radiological diagnosis and treatment resources in various districts. There is a certain degree of unbalanced distribution and inadequate utilization of radiological diagnosis and treatment resources in Beijing.
ABSTRACT
Background: Self-medication is a common practice across the world and its consequences e.g. misdiagnosis, wrong diagnosis, irrational use of drug, adverse drug reaction, and antimicrobial resistant are cause of concern. The students of medicine, dentistry, pharmacy, paramedical courses are among the most vulnerable class for its practice. The study was to assess the extent and factors influencing self-medication among undergraduate dental students. Methods: A cross-sectional study was carried out, that included 1st, 2nd and 3rd year students of dental college in Delhi. A semi-structured questionnaire consisting of demographic questions and questions on knowledge, attitude and practices of self-medication in the last six months was prepared and distributed among students. Questions on food supplements were also asked. Results: Of a total of 154 students, 39 % reported at least one minor episode of illness, (61%) of them practiced self-medication and 30.1% of the students also advised medicines to other. Most common source of advice was family and friends (45.3%) followed by chemists and books. Most common self-medicated drugs were paracetamol followed by cetirizine. Most Common reported illness for self-medication were fever (41.5%) followed by cough and common cold (24.4%). A significant number has used food supplements and drugs of alternative medicines. Conclusion: Prevalence of self-medication among dental students is high that needs to be intervened at different stratas. Academician and health professionals need to educate students about the rational use of drug and impact of irrational prescribing.
