Objective: To analyze the burden of cardiovascular disease (CVD) caused by lead pollution exposure in China from 1990 to 2019.
Methods: Utilizing data from the Global Burden of Disease 2019 (GBD 2019), this research examines the changes in the number of CVD deaths, deaths rates, disability-adjusted life years (DALYs) and DALY rates, as well as their age-normalization rates, due to lead pollution exposure in China from 1990 to 2019. Joinpoint was used to estimate average annual percentage of change (AAPC) and reflect the time change trend of the burden of CVD caused by lead pollution exposure in China, the world and different socio-demographic index (SDI) regions.
Results: The age-standardized mortality rate and age-standardized DALY rate showed a decreasing trend in China from 1990 to 2019, with an average annual decrease of -1.17% (95% confidence interval (CI): -3.49~-3.14, P<0.05) and -1.90% (95% CI: -2.04~-1.75, P<0.05), respectively. In 2019, age-standardized CVD mortality and DALY rates attributed to lead exposure in China were higher than those in the global, high-SDI, medium-high SDI and moderate SDI regions. In 2019, 5.94% of CVD deaths in China were caused by lead exposure. Compared to 1990, the number of attributable deaths and mortality increased by 0.73% and 0.44%, respectively, and the attributable DALY and DALY rates increased by 30.04% and 8.22%, respectively. From 1990 to 2019, the mortality rate and DALY rate of males were higher than those of females, and the mortality rate and DALY rate increased with the increase of age, reaching the highest in the age group of 70 years and above.
Conclusion: In 2019, the standardized death rate of CVD and the standardized DALY rate attributed to lead pollution exposure in China were higher than those in the global regions with high SDI, medium-high SDI and medium SDI. The findings highlight demographic disparities in CVD deaths and DALYs attributable to lead exposure, with males and the elderly identified as high-risk groups.

Our study focused on specific ChR2 variants, particularly those with the Step function Opsins (SFO) mutation at the D156-C128 gate. These are widely used in optogenetics due to their heightened sensitivity to light and bi-stable prolonged activation. However, in some ChR2 variants, specifically D156 mutants, a tail current occurs when continuous light exposure is stopped.

Sepsis-associated encephalopathy (SAE) is a severe and frequent septic complication, characterized by neuronal damage as key pathological features. The astrocyte-microglia crosstalk in the central nervous system (CNS) plays important roles in various neurological diseases. However, how astrocytes interact with microglia to regulate neuronal injury in SAE is poorly defined.

Introduction: It is currently uncertain whether smoking is a risk factor for carpal tunnel syndrome (CTS). This study aims to elucidate association between smoking and CTS using Mendelian randomization (MR) analysis.
Methods: This study was a secondary analysis of publicly available GWAS data, using four smoking phenotypes (smoking initiation, smoking status, lifetime smoking, and never smoking) as exposures, and two CTS datasets (discovery and validation sets) as outcomes for MR analysis.

This paper presents a compact all-fiber multicomponent gas Raman probe using a dual-fiber architecture within a platinum-coated capillary. The probe eliminates the need for conventional optical components like filters and dichroic mirrors by strategically employing metal coating on the excitation fiber's surface to suppress interference signals. A detailed analysis of the silica Raman signal and fluorescence propagation within the system facilitated this design.

Background: The association of plasma metals on the risk of cardiovascular diseases (CVD) in adults with prediabetes remains poorly investigated. To assess the association between plasma metal exposure and the risk of CVD in prediabetic adults in the United States using five plasma metals.
Methods: Five cycles of data (2011-2012, 2013-2014, 2015-2016, and 2017-2018) from the NHANES were adopted in this study.
