[Comparison of Disease Burden Factors of Thyroid Cancer Between China and the World From 1990 to 2019].

Objective To compare the prevalence and disease burden of thyroid cancer and their trends between China and the globe from 1990 to 2019.Methods With the global disease burden data in 2019,Joinpoint was used to predict the trends of the disease burden of thyroid cancer in China and the globe from 1990 to 2019,and logarithmic linear model was used to test the predicted trends.The R language was used for predictive analysis and graphic plotting of the disease burden from 2020 to 2035.

Downregulation of circFASTKD1 ameliorates myocardial infarction by promoting angiogenesis.

Circular RNAs (circRNAs), a novel class of endogenous long non-coding RNAs, have attracted considerable attention due to their closed continuous loop structure and potential clinical value. In this study, we investigated the function of circFASTKD1 in vascular endothelial cells. CircFASTKD1 bound directly to miR-106a and relieved its inhibition of Large Tumor Suppressor Kinases 1 and 2, thereby suppressing the Yes-Associated Protein signaling pathway.

Paclitaxel-mediated human aryl hydrocarbon receptor mRNA translation by an internal ribosomal entry site-dependent mechanism.

The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that is best known in mediating the toxicities of dioxins and dioxin-like compounds. AHR is activated by a variety of endogenous ligands and participating in tumor development. Thus, it will provide a new approach for cancer prevention and treatment to study the translation mechanism of AHR in tumor cells.

ATF2 translation is induced under chemotherapeutic drug-mediated cellular stress via an IRES-dependent mechanism in human hepatic cancer Bel7402 cells.

Activating transcription factor (ATF) 2 is a member of the ATF/cyclic AMP-responsive element binding protein family, which exhibits both oncogenic and tumor-suppressor functions. In our preliminary experiments, it was observed that the expression of the ATF2 protein was induced following treatment with adriamycin (ADR) and paclitaxel (PTX), which may be regulated by internal ribosome entry segment (IRES)-mediated translation. By constructing a bicistronic vector containing the ATF2 5'-untranslated region (UTR), it was demonstrated that the ATF2 5'-UTR contains an IRES and maps a 30-nucleotide (nt) sequence (from nt 299 to nt ~269), which was essential for the IRES activity.

Ischemic Postconditioning Before Percutaneous Coronary Intervention for Acute ST-Segment Elevation Myocardial Infarction Reduces Contrast-induced Nephropathy and Improves Long-term Prognosis.

Background And Aims: Contrast-induced nephropathy (CIN) after percutaneous coronary intervention (PCI) is one of the major adverse outcomes affecting the prognosis of patients with acute ST-segment elevation myocardial infarction (STEMI). Ischemic postconditioning prior to PCI (pre-PCI) in patients with STEMI is hypothesized to be protective against CIN after PCI.

Methods: A total of 251 patients with STEMI were randomized into two groups: ischemic postconditioning group (n = 123, age, 61.

[Triple-phase helical CT in the differential diagnosis between small hepatocellular carcinoma and small hepatic cavernous hemangioma].

Objective: To scrutinize the enhancement pattern at hepatic arterial phase (HAP), portal venous phase (PVP) and delayed phase (DP) by helical CT examination in order to differentiate small hepatocellular carcinoma (SHCC) from small hepatic cavernous hemangioma (SHCH).

Methods: In 38 patients (41 lesions) with SHCC and 35 patients (45 lesions) with SHCH, the images at HAP, PVP and DP were recorded as to the characteristic of enhancements with the average CT value at the HAP monitored and compared.

Results: The enhancement patterns of SHCC at the HAP, PVP, and DP were assessed as hyper-hypo-hypodense in 20 lesions, hyper-iso-hypodense in 6 lesions, hyper-hyper-hypodense in 3 lesions, hyper-iso-isodense in 5 lesions, iso-hypo-hypodense in 3 lesions, and hypo-hypo-hypodense in 4 lesions.
