Global, regional, and national burden of myocarditis in children aged 0-14 years, 1990-2021: analysis for the global burden of disease study 2021.

Objective: There are limited epidemiological data on myocarditis in children aged 0-14 years. This study aims to investigate the trends in incidence, mortality, disability-adjusted life years (DALYs), and corresponding estimated annual percentage change (EAPC) of myocarditis in children aged 0-14 years from 1990 to 2021.

Methods: We utilized the 2021 Global Burden of Disease, Injuries, and Risk Factors Study (GBD) analytical tools to examine the incidence, mortality, and DALYs of myocarditis in children aged 0-14 years, considering factors such as age, sex, region, sociodemographic index (SDI), and data from 204 countries or regions.

F-18 FDG in conjunction with 11C-choline PET/CT in the diagnosis of hepatocellular carcinoma.

Purpose: F-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET)/computed tomography (CT) alone has limited sensitivity for the diagnosis of hepatocellular carcinoma (HCC). We hoped to improve the diagnostic sensitivity by combining F-18 FDG and C-choline PET/CT.

Materials And Methods: A total of 76 consecutive patients with HCC were prospectively enrolled.

Preliminary study on the evaluation of olfactory neuroblastoma using PET/CT.

Purpose: Because of paucity of data available regarding the utility of PET/CT in the diagnosis and staging of patients with olfactory neuroblastoma (ONB), we retrospectively analyzed the efficacy of PET/CT in 9 patients with ONB.

Materials And Methods: Whole-body F-18 FDG PET/CT was performed in 7 patients with newly diagnosed ONB, as well as in 1 patient with recurrence and in 1 patient with remnant tumor. Regional C-11 choline (C-11 CHO) PET/CT was performed in 2 patients with negative F-18 FDG scans.

Utility of 18F-FDG PET/CT for staging NK/T-cell lymphomas.

Purpose: Extranodal natural killer (NK)/T-cell lymphoma is a rare neoplasm and limited data has reported regarding the utilization of fluorine-18, fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) in this disease. The aim of this study was to assess the role of F-FDG PET/CT in the staging of NK/T-cell lymphomas.

Patients And Methods: Thirteen newly diagnosed and two recurrent patients with NK/T-cell lymphoma who received F-FDG PET/CT were studied.

[Construction of a retroviral vector for RNA interference targeting human telomerase reverse transcriptase].

Objective: To construct a recombinant retroviral vector for RNA interference targeting human telomerase reverse transcriptase (hTERT).

Methods: The sequences coding for enhanced fluorescence protein (EGFP), U6 promoter and a small interfering RNA (siRNA) targeting hTERT were amplified by PCR, respectively, and sub-cloned sequentially into the retroviral shuttle plasmid pLXSN to construct the plasmid pLXSN-EGFP-U6-siTERT. The recombinant expression plasmid was identified by restriction enzyme digestion and sequencing.
