Geographic entity matching is an important means for multi-source spatial data fusion and information association and sharing. Corresponding matching methods have been designed by existing studies for different types of entity data characteristics, such as line and area. However, these approaches are often limited in the generalization ability for matching heterogeneous data from multiple sources and the accuracy for complex pattern matching.

Then, the dosimetric differences caused by motion were analyzed.
Methods: Thirty-two UCC patients were included.
Giant cell tumour of tendon sheath (TSGCT) is an uncommon soft tissue tumor, especially in its diffuse subtype (D-TSGCT), which is rare and associated with a high recurrence rate after treatment.

Methods: This retrospective study analyzed 99 HCC patients (145 lesions) who underwent MR simulation. T-weighted imaging (TWI), contrast-enhanced TWI (CE-TWI) at 15 s, 45 s, 75 s, 150 s, and 20 min after contrast agent injection were performed, comprising a total of six imaging sequences.
Tubulin is a critical target for cancer therapy, with colchicine binding site inhibitors (CBSIs) being the most extensively researched. A series of quinazoline derivatives designed to target the colchicine binding site of tubulin were synthesized and evaluated for their biological activities. The antiproliferative effects of these compounds were tested against six human cancer cell lines, and compound Q19 demonstrated potent antiproliferative activity against the HT-29 cell line, with an IC value of 51 nM.

Methods: Sixty-five children with mild to moderate asthma who were under regular inhaled corticosteroid (ICS) treatment for more than 1 year but whose FEF remained below 65% of the predicted value and had positive results for serum Der p or Der f were enrolled. Children with asthma underwent house dust mite (HDM) subcutaneous immunotherapy (SCIT) treatment for 1 year.
Online adaptive radiation therapy (ART) eliminates interfraction uncertainties by adaption before each treatment session. However, intrafraction motions still exist and could become more severe due to long treatment time. Large isotropic margins can ensure clinical target volume (CTV) coverage but at the cost of more organs at risk damage.

Methods: In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial conducted in China, we enrolled participants 1 to 24 months of age who were hospitalized with RSV infection.
Background: Laparoscopic partial nephrectomy (LPN) is a standard surgical treatment option for renal tumors. Prior to LPN, it is necessary to evaluate the tumor condition and develop a surgical plan using precise imaging.
Objective: To explore the clinical application value of 3D virtual model (3DVM) in LPN.
Introduction: The occurrence of Spinal cord injury (SCI) brings economic burden and social burden to individuals, families and society, and the complications after SCI greatly affect the rehabilitation and treatment of patients in the later stage.This study focused on the potential biomarkers that co-exist in SCI and sarcopenia, with the expectation to diagnose and prognose patients in the acute phase and rehabilitation phase using comprehensive data analysis.
Methods: The datasets used in this study were downloaded from Gene Expression Omnibus (GEO) database.
The aim of this study was to establish and validate the precision of a novel radiomics approach that integrates 18Fluorine-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)-computed tomography (CT) scan data with clinical information to improve the prognostication of survival rates in patients diagnosed with stage III Non-Small Cell Lung Cancer (NSCLC) who are not candidates for surgery. We evaluated pretreatment F-FDG PET-CT scans from 156 individuals diagnosed with stage III inoperable NSCLC at Shandong Cancer Hospital. These individuals were divided into two groups: a training set comprising 110 patients and an internal validation set consisting of 46 patients.
