Analysis and prediction of central nervous system tumor burden in China during 1990-2030.

Central nervous system (CNS) tumors, due to their unique locations, pose a serious threat to human health and present challenges to modern medicine. These tumors exhibit notable epidemiological characteristics across various ethnicities, regions, and age groups. This study investigated the trend of disease burden of CNS tumors in China from 1990-2019 and predicted the incidence and death rate from 2020-2030.

A case of collagenous gastritis and literature review: A case report.

Rational: Collagenous gastritis (CG) is rarely encountered in clinical practice. Here, we reported a case of CG with iron-deficiency anemia as the main symptom.

Patient Concerns: The patient was a 26-year-old woman who sought medical advice with a chief complaint of recurrent upper abdominal distention and anemia since the last 3 years.

Manganese potentiates lipopolysaccharide-induced innate immune responses and septic shock.

Divalent metal ions such as magnesium (Mg), manganese (Mn), and zinc (Zn) play important roles in regulating innate immune responses. Lipopolysaccharide stimulation led to increased intracellular Mn and Zn in macrophages. However, the effect of those metal ions in regulating lipopolysaccharide-induced innate immune responses remains unclear.

A secreted effector with a dual role as a toxin and as a transcriptional factor.

Bacteria have evolved multiple secretion systems for delivering effector proteins into the cytosol of neighboring cells, but the roles of many of these effectors remain unknown. Here, we show that Yersinia pseudotuberculosis secretes an effector, CccR, that can act both as a toxin and as a transcriptional factor. The effector is secreted by a type VI secretion system (T6SS) and can enter nearby cells of the same species and other species (such as Escherichia coli) via cell-cell contact and in a contact-independent manner.

Gender differences in bicuspid aortic valve Sievers types, valvulopathy, aortopathy, and outcome of aortic valve replacement.

Background: The gender difference of the bicuspid aortic valve (BAV) is not well understood.

Objectives: We evaluated the impact of gender on the Sievers types, valvulopathy, aortopathy, and outcomes of aortic valve replacement (AVR) of BAV patients in a cohort of Chinese patients.

Methods: Among 992 BAV patients without aortic dissection nor congenital heart disease, 658 underwent AVR.

Prognostic value of coronary flow velocity reserve in patients with homozygous familial hypercholesterolemia.

Coronary flow velocity reserve (CFVR) can provide useful quantitative information on the functional status of coronary artery circulation, and an impaired CFVR (< 2.0) was associated with a significant increase in the occurrence of cardiac events. Coronary artery disease (CAD) is the leading cause of death in homozygous familial hypercholesterolemia (HoFH), but the relationship between impaired CFVR and outcome in HoFH has never been discussed before METHODS: To explore the long-term prognostic value of CFVR in patients with HoFH, 39 HoFH patients with CFVR data (mean age with 16.

The transcriptional regulator Zur regulates the expression of ZnuABC and T6SS4 in response to stresses in Yersinia pseudotuberculosis.

Zinc homeostasis is crucial for the development and stress resistance of bacteria in the environment. Serial zinc sensing transcriptional regulators, zinc transporters and zinc binding proteins were found to maintain the zinc homeostasis in bacteria. Zur is a zinc uptake regulator that is widely distributed in species, and ZnuABC, as well as the Type VI Secretion System (T6SS4) function in zinc acquisition.

Supravalvular Aortic Stenosis and the Risk of Premature Death Among Patients With Homozygous Familial Hypercholesterolemia.

Patients with homozygous familial hypercholesterolemia (HoFH) have a high risk for premature death. Supravalvular aortic stenosis (SVAS) is a common and the feature lesion of the aortic root in HoFH. The relation between SVAS and the risk of premature death in patients with HoFH has not been fully investigated.
