Objective:To identify tooth number abnormalities on pediatric panoramic radiographs based on deep learning.Methods:Eight hundred panoramic radiographs of children aged 4 to 11 years meeting the inclusion and exclusion criteria were selected and randomly assigned by writing programs in Python (version 3.9) to the training set (480 images), verification set (160 images) and internal test set (160 images), taken in Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology between November 2012 to August 2020. And all panoramic radiographs of children aged 4 to 11 years taken in the First Outpatient Department of Peking University School and Hospital of Stomatology from June 2022 to December 2022 were collected as the external test set (907 images). All of the 1 707 images were obtained by operators to determine the outline and to label the tooth position of each deciduous tooth, permanent tooth, permanent tooth germ and additional tooth. The deep learning model with ResNet-50 as the backbone network was trained on the training set, validated on the verification set, tested on the internal test set and external test set. The images of test sets were divided into two categories according to whether there was abnormality of tooth number, to calculate sensitivity, specificity, positive predictive value and negative predictive value, and then divided into four types of extra teeth and missing permanent teeth both existed, extra teeth existed only, missing permanent teeth existed only, and normal teeth number, to calculate Kappa values. Results:The sensitivity, specificity, positive predictive value and negative predictive value were 98.0%, 98.3%, 99.0% and 96.7% in the internal test set, and 97.1%, 98.4%, 91.9% and 99.5% in the external test set respectively, according to whether there was abnormality of tooth number. While images were divided into four types, the Kappa value obtained in the internal test set was 0.886, and that in the external test set was 0.912. Conclusions:In this study, a deep learning-based model for identifying abnormal tooth number of children was developed, which could identify the position of additional teeth and output the position of missing permanent teeth on the basis of identifying normal deciduous and permanent teeth and permanent tooth germs on panoramic radiographs, so as to assist in diagnosing tooth number abnormalities.

Objective:To explore the risk factors for 30-day death in emergency department patients, and then construct a prediction model and validate it using nomogram.Methods:A retrospective cohort study was conducted. The clinical data of 1 091 patients admitted to the emergency department of the First People's Hospital of Changde from January 1 to June 30, 2021 was collected, including 741 patients from January 1 to March 31 in the development group and 350 patients from April 1 to June 30 in the validation group. General information, first vital signs admitted to the emergency department, and laboratory results were collected, the modified early warning score (MEWS) was calculated, and 30-day outcomes were recorded. Univariate and multivariate Logistic regression analysis was used to screen out the risk factors of 30-day death. According to the results of multivariate analysis, the nomogram was used to construct a 30-day death prediction model. The receiver operator characteristic curve (ROC curve) was used to evaluate the consistency of the prediction model, the calibration of the prediction model was evaluated by the Hosmer-Lemeshow goodness of fit test.Results:A total of 1 091 patients were enrolled. There were 741 patients in the development group, including 356 males and 385 females, aged (51.42±17.33) years old, and the 30-day mortality was 28.88%. There were 350 patients in the validation group, including 188 males and 162 females, aged (52.88±16.11) years old, and the 30-day mortality was 24.00%. The results of the univariate analysis showed that age, primary diagnosis on admission, consciousness, respiratory rate (RR), systolic blood pressure (SBP), heart rate (HR), pulse oxygen saturation (SpO 2), MEWS score, erythrocyte sedimentation rate (ESR), procalcitonin (PCT) and body mass index (BMI) might be the risk factors for 30-day death in patients in the emergency department. The results of the multivariate analysis showed that the MEWS score [odds ratio ( OR) = 14.22, 95% confidence interval (95% CI) was 1.46-138.12], ESR ( OR = 46.71, 95% CI was 20.48-106.53), PCT ( OR = 4.97, 95% CI was 2.46-10.02), BMI (24.0-27.9 kg/m 2: OR = 37.82, 95% CI was 14.69-97.36; ≥28.0 kg/m 2: OR = 62.11, 95% CI was 25.77-149.72) were independent risk factors for 30-day death in the emergency department (all P < 0.05). Using the four variables with the results of multivariate analysis to construct a nomogram prediction model, the area under the ROC curve (AUC) was 0.974 (95% CI was 0.753-0.983) for the development group, and the AUC was 0.963 (95% CI was 0.740-0.975) for the validation group. The Hosmer-Lemeshow test showed no statistically significant difference between the predicted outcome of the nomogram prediction model and the actual occurrence ( χ2 = 1.216, P = 1.270). Conclusion:The prediction model developed by the MEWS score combined with BMI, ESR and PCT can scientifically and effectively predict the 30-day outcome of emergency department patients.

Total hip arthroplasty plays a key role in the end-stage diagnosis and treatment of a variety of femoral and hip diseases, but the risk of dislocation caused by traditional bone cement prosthesis has always been one of the key constraints of total hip arthroplasty. Bousquet added a polymer lining between the femoral head and acetabulum to separate the activities between the lining and acetabulum. The dual mobility acetabular cup system can effectively reduce the incidence of prosthesis dislocation. The first generation of the dual mobility acetabular cup system is lined with polyethylene. With the progress of modern material medicine technology, a new type of the dual mobility acetabular cup system with smooth surface, bionic coating and high cross-linked polyethylene liner has been gradually formed, and its performance has been improved. Because of the existence of the inner liner, the distance between the femoral head and acetabulum of the dual mobility acetabular cup system is larger, which can allow greater range of motion, has higher stability, is not easy to dislocate, and has lower wear degree of the prosthesis at the same time. Therefore, the dual mobility acetabular cup system is more and more widely used in clinical practice, especially for the elderly with high risk of dislocation, revision surgery or neuromuscular dysfunction. But on the other hand, based on the design principle of dual motion total hip prosthesis, the disadvantages such as intraprosthetic dislocation caused by multiple factors and the lack of fixation holes result in the dual motion total hip system easily triggering acetabular loosening when targeting patients such as severe bone defects, thus limiting its further use. The dual motion total hip system can be tailored to different clinical applications, such as for populations with different characteristics, and for different methods of primary surgery, with different application strategies, thereby reducing the incidence of postoperative revision. In this paper, we take the application of the dual motion total hip acetabular system in the total hip arthroplasty as the core, and the system puts forth the principle of the dual motion total hip acetabular system, compared with traditional bone materials, introduces its advantages and disadvantages, and reveals its application strategy in the clinic, and gives an outlook for the future application of the dual motion total hip acetabular system in orthopedics.

Objective: To compare the reliability of Internet Addiction Impairment Index (IAII), Revised Chen Internet Addiction Scale(CIAS-R)-Taiwan Revision, CIAS-R-Mainland Revision, Young Diagnostic Questionnaire (YDQ) and the consistency of Internet addiction using the four scales in college students. Methods: A total of 1 004 undergraduates from 3 universities in Hefei were selected to measure the tendency of internet addiction simultaneously using the four scales, and 122 students were re tested two weeks after the initial assessment. Correlation coefficient, coincidence rate and Kappa value were used to analyze the consistency of the four scales. Analysis of variance, t test and Logistic regression were used to determine the consistency of the factors related to internet addiction scale. Results: The reliability of the four Internet addiction scales were greater than 0.7( P <0.01). The correlation coefficient among all scales was greater than 0.5( P <0.01). The agreement between YDQ and CIAS-R-Mainland Revision was 0.87. The Kappa value of YDQ and CIAS-R-Taiwan Revision in the consistency analysis was 0.51( P <0.01), the Kappa value between the other scales was less than 0.5. Results showed that the four scales were consistent in Internet addiction prevalence by gender, grade and major, while CIAS-R-Taiwan Revision and YDQ were not consistent with the other two scales in sleep disorder. Conclusion The four Internet addiction scales all have good reliability, while low agreement in Internet addiction assessment, suggesting further improvement and revision in Internet addiction scales.
