Mechanisms of MALAT1 regulating proliferative diabetic retinopathy via targeting miR-126-5p.

Objective: Diabetic retinopathy (DR) is the primary reason for blindness among the middle-aged and elderly. It can progress to proliferative diabetic retinopathy (PDR), a condition that is accompanied by retinal neovascularization as the disease worsens. Understanding the pathogenesis of PDR can facilitate the development of treatments.

Sleep quality as a mediator of the relationship between screen time and negative emotions among Chinese college freshmen.

College freshmen are special populations facing great challenges in adapting to the brand new environment, and their lifestyle and emotional states are worthy of attention. Especially during the COVID-19 pandemic, their screen time and prevalence of negative emotions were significantly increased, but few studies have focused on such situation of college freshmen and illustrated relevant mechanisms. Thus, based on a sample of Chinese college freshmen during the COVID-19 pandemic, the current study aimed to investigate the association between their screen time and negative emotions (depression, anxiety and stress), and further explore the mediating effects of sleep quality.

Research indicates that sleep problem is a behavioral risk factor of obesity. However, few research have applied a multi-dimensional approach to investigate the relationship between sleep health and adiposity. Therefore, the current study aimed to examine the associations of sleep characteristics (duration, quality) and chronotype with overweight/obesity as measured by body mass index.

Physical activity mitigates the influence of blood cadmium on memory function: a cross-sectional analysis in US elderly population.

Current evidence showed that heavy metal exposure including cadmium (Cd) exposure might contribute to memory function impairment in youth, while this association has not been extensively explored in senior groups. Complementary therapy like physical activity (PA) is proved to enhance memory; however, the combined effects of Cd exposure and PA are interesting issues worth investigating. Cross-sectional data from the National Health and Nutrition Examination Survey (NHANES) 2011-2014 were analyzed.

Therefore, it is vital to explore the relationship between iron metabolism and ovarian cancer and to identify novel markers for diagnostics and therapeutics.

A robust microsatellite instability detection model for unpaired colorectal cancer tissue samples.

Background: Microsatellite instability (MSI) is a key biomarker for cancer immunotherapy and prognosis. Integration of MSI testing into a next-generation-sequencing (NGS) panel could save tissue sample, reduce turn-around time and cost, and provide MSI status and comprehensive genomic profiling in single test. We aimed to develop an MSI calling model to detect MSI status along with the NGS panel-based profiling test using tumor-only samples.

Pre-existing immunity to SARS-CoV-2 associates with strong T cell responses induced by inactivated COVID-19 vaccines.

Individuals with a recent common cold coronavirus infection, which leads to pre-existing immunity against SARS-CoV-2, displayed a less severe course of COVID-19. However, the relationship between pre-existing immunity against SARS-CoV-2 and the inactivated-vaccine-induced immune response is still unknown. Here, 31 healthcare workers who received standard two doses of inactivated COVID-19 vaccines (Weeks 0 and 4, respectively) were enrolled, vaccine-induced neutralization and T cell responses were detected, and the correlation between the pre-existing SARS-CoV-2-specific immunity was analyzed.

Comparison of the clinical efficacy of laparoscopic extralevator abdominoperineal excision (ELAPE) and non-ELAPE for low rectal cancer.

This study was performed to retrospectively analyze and compare the related clinical indicators between extralevator abdominoperineal excision (ELAPE) and non-ELAPE under laparoscopic for low rectal cancer. From June 2018 to September 2021, a total of 80 patients with low rectal cancer who underwent either of the above two types of surgeries at our Hospital were enrolled. Patients were divided into the ELAPE group and non-ELAPE group based on the different surgical methods.

Body mass index, C-reactive protein, and pancreatic cancer: A Mendelian randomization analysis to investigate causal pathways.

Aim: To explore whether C-reactive protein (CRP) mediates the risk of body mass index (BMI) in pancreatic cancer (PC) and calculate the mediate proportion of CRP in this possible mechanism.

Methods: Based on two-sample Mendelian randomization (TSMR), a two-step Mendelian randomization (TM) model was conducted to determine whether CRP was a mediator of the causal relationship between BMI and PC. The multivariable Mendelian randomization (MVMR) study was designed for mediating analysis and to calculate the mediating proportion mediated by CRP.

Expression and significance of histone methyltransferase SET domain containing 2 with histone H3 lysine 36 trimethylation in mouse hepatic oval cells differentiated into bile duct epithelial cells .

The present study aimed to identify the function and expression of trimethylated protein histone H3 lysine 36 (H3K36)me3 and the upstream specific enzyme histone methyltransferase SET domain containing 2 (SETD2), during the differentiation of hepatic oval cells (HOCs) into cholangiocytes in mice following partial liver resection and fed with 2‑acetamidofluorene. HOCs were isolated from Kunming male mice fed with 2‑acetamidofluorene for 10 days. Their liver tissues were then isolated following partial liver resection and another week of 2‑acetamidofluorene treatment.
