Deep learning-based automated diagnosis of temporomandibular joint anterior disc displacement and its clinical application.

Introduction: This study aimed to develop a deep learning-based method for interpreting magnetic resonance imaging (MRI) scans of temporomandibular joint (TMJ) anterior disc displacement (ADD) and to formulate an automated diagnostic system for clinical practice.

Methods: The deep learning models were utilized to identify regions of interest (ROI), segment TMJ structures including the articular disc, condyle, glenoid fossa, and articular tubercle, and classify TMJ ADD. The models employed Grad-CAM heatmaps and segmentation annotation diagrams for visual diagnostic predictions and were deployed for clinical application.

Correlation Between Temporomandibular Joint Disc Perforation and Degenerative Joint Changes: A CBCT and Clinical Analysis.

Objectives: To analyse the correlation between temporomandibular joint (TMJ) disc perforation and degenerative joint changes (DJC) on cone-beam computed tomography (CBCT) and related factors.

Study Design: A total of 238 female patients with anterior disc displacement without reduction (ADDwoR), accounting for 348 affected joints, requiring TMJ disc open anchorage surgery were included in the study conducted from June 2021 to August 2022. Following TMJ disc open anchorage surgery, patients were divided into two groups: disc perforation (DP) and disc non-perforation (DNP).

Anxiety and depressive symptoms among COVID-19 patients in Jianghan Fangcang Shelter Hospital in Wuhan, China.

Fangcang shelter hospitals were established in China during the coronavirus disease 2019 (COVID-19) pandemic as a countermeasure to stop the spread of the disease. To our knowledge, no research has been conducted on mental health problems among patients in Fangcang shelter hospitals. This study aimed to determine the prevalence and major influencing factors of anxiety and depressive symptoms among COVID-19 patients admitted to Fangcang shelter hospitals.

Quantitative analysis of contrast-enhanced ultrasonography in acute radiation-induced liver injury: An animal model.

The aim of the present study was to examine and assess contrast-enhanced ultrasound in the early diagnosis of acute radiation-induced liver injury in a rat model. Sixty female rats were used, with 50 rats being utilized to produce an animal model of liver injury with a single dose of stereotactic X-ray irradiation of 20 Gy. Ten rats from the injury group and 2 rats from the control group were randomly selected on days 3, 7, 14, 21 and 28, and examined by contrast-enhanced ultrasound and histopathology of liver specimens.

[Differential expression in ACE2, Ang(1-7) and Mas receptor during progression of liver fibrosis in a rat model].

Objective: To investigate the changes in expression of the ACE2/Ang(1-7)/Mas receptor axis' components that occur during progression of liver fibrosis using a rat model system.

Methods: Thirty-six adult male Wistar rats, were randomly assigned to groups of normal control (n = 6; no manipulation) and liver fibrosis (n = 30; given a subcutaneous injection of 40% chronic carbon tetrachloride (CCl4)). At post-injection days 15, 30, 45, 60 and 75, 1 control rat and 6 modeled rats were sacrificed for analysis.

[Color Doppler in differential diagnosis of scrotal mass].

Objective: To evaluate the differential diagnosis of scrotal mass with color Doppler ultrasound.

Methods: Retrospective analysis was made of 21 cases of scrotal mass confirmed both surgically and pathologically in our hospital.

Results: Eight of the total number were malignancy of the testis origin, accounting for 38.

Involvement of caspase-3 activation in squamocin-induced apoptosis in leukemia cell line HL-60.

Annonaceous acetogenins have potent antitumor effect in vitro and in vivo. Squamocin is one of the annonaceous acetogenins and has been reported to have antiproliferative effect on cancer cells. Our results from this study showed that squamocin inhibited proliferation of HL-60 cells with IC50 value of 0.
