Importance: Childhood adverse experiences have been linked with long-term risk of cardiovascular disease (CVD), yet the transgenerational associations between interparental behaviors and CVD remain poorly understood.

Objectives: To explore the association between exposure to childhood interparental physical violence and the subsequent risk of CVD and to examine whether the association is modified by adult depressive symptoms.

Design, Setting, And Participants: This population-based cohort study included data from the China Health and Retirement Longitudinal Study (CHARLS), an ongoing study recruiting individuals aged 45 years or older, dated between June 1, 2011, and December 31, 2020, with a follow-up duration of 9 years.

Article Synopsis
  • - The study examined the relationship between remnant cholesterol and low-density lipoprotein cholesterol (LDL-C) and their impact on stroke risk in two large Chinese health cohorts (CHARLS and CHNS), focusing on individuals aged 45 and older.
  • - Researchers found that participants with elevated remnant cholesterol had a higher risk of stroke, and those in the "discordantly high" remnant cholesterol group had significantly increased stroke risks compared to those with "discordantly low" remnant cholesterol levels.
  • - The findings suggest that discrepancies between remnant cholesterol and LDL-C levels are linked to stroke risk among Chinese adults, even in those with normal LDL-C levels, highlighting the importance of remnant cholesterol in cardiovascular health.

Background: Triglyceride and glucose (TyG) index, a surrogate marker of insulin resistance, has been validated as a predictor of cardiovascular disease. However, effects of TyG-related indices combined with obesity markers on cardiovascular diseases remained unknown. We aimed to investigate the associations between TyG index and modified TyG indices with new-onset cardiovascular disease and the time-dependent predictive capacity using a national representative cohort.

Article Synopsis
  • The study investigated how the triglyceride-glucose (TyG) index and inflammation (measured by high-sensitivity C-reactive protein or hsCRP) together affect the risk of cardiovascular diseases in middle-aged and older Chinese adults using data from a national study (CHARLS).
  • Involving 8,658 participants free of cardiovascular diseases at the start, the research found that those with high levels of both TyG and hsCRP had significantly higher risks of developing heart disease and stroke during the 7-year follow-up.
  • The study also revealed that inflammation (hsCRP) contributed to 13.4% of the link between the TyG index and cardiovascular diseases,

Purpose: The debate over the causal and longitudinal association between cystatin C and stroke in older adults persists. Our aim was to assess the link between cystatin C levels, both measured and genetically predicted, and stroke risk.

Methods: This study employed a retrospective cohort design using samples of the China Health and Retirement Longitudinal Study (CHARLS), which is a nationally representative cohort recruiting individuals aged 45 years or above.

Background: Previous studies have confirmed the separate effect of arterial stiffness and obesity on type 2 diabetes; however, the joint effect of arterial stiffness and obesity on diabetes onset remains unclear.

Objective: This study aimed to propose the concept of arterial stiffness obesity phenotype and explore the risk stratification capacity for diabetes.

Methods: This longitudinal cohort study used baseline data of 12,298 participants from Beijing Xiaotangshan Examination Center between 2008 and 2013 and then annually followed them until incident diabetes or 2019.

Article Synopsis
  • Arterial stiffness significantly contributes to health issues globally, and the study investigates its link with diabetes and glycemic control to help manage these conditions better.
  • Data from 5,837 participants over a median follow-up of 4 years revealed that those with diabetes had a 48.4% higher risk of developing arterial stiffness, especially when glucose levels were poorly managed.
  • Maintaining good glycemic control was found to lower this risk, highlighting the importance of diabetes management in preventing arterial stiffness and related health problems.

Background And Aims: Dyslipidemia is known to contribute to arterial stiffness, while the inverse association remains unknown. This study aimed to explore the association of baseline arterial stiffness and its changes, as determined by brachial-ankle pulse wave velocity (baPWV), with dyslipidemia onset in the general population.

Methods: This study enrolled participants from Beijing Health Management Cohort using measurements of the first visit from 2012 to 2013 as baseline, and followed until the dyslipidemia onset or the end of 2019.

Background: The triglyceride-glucose (TyG) index is a predictor of cardiovascular diseases; however, to what extent the TyG index is associated with cardiovascular diseases through renal function is unclear. This study aimed to evaluate the complex association of the TyG index and renal function with cardiovascular diseases using a cohort design.

Methods: This study included participants from the China Health and Retirement Longitudinal Study (CHARLS) free of cardiovascular diseases at baseline.

Objective: This study aims to explore the mechanism of miR-30d-5p in regulating the development of lung squamous cell carcinoma (LUSC) via targeting .

Methods: Bioinformatics methods were employed to analyze the differentially expressed genes in LUSC tissue microarray. qRT-PCR was employed to detect the expression of miR-30d-5p and mRNA in normal human bronchial epithelial cells and LUSC cells.

Background: The efficacy of next-generation epidermal growth factor receptor-tyrosine kinase inhibitors in patients with advanced non-small cell lung cancer who have failed first-generation epidermal growth factor receptor-tyrosine kinase inhibitors still remains under investigation.

Objective: The aim of this meta-analysis was to systematically assess the efficacy and safety profiles of next-generation epidermal growth factor receptor-tyrosine kinase inhibitors in patients with advanced non-small cell lung cancer who failed first-generation epidermal growth factor receptor-tyrosine kinase inhibitors.

Methods: We performed a comprehensive search of several electronic databases up to September 2018 to identify clinical trials.

Apolipoprotein A-II (ApoA-II) is the second most abundant protein constituent of high-density lipoprotein (HDL). The physiologic role of ApoA-II is poorly defined. ApoA-II may inhibit lecithin:cholesterol acyltransferase and cholesteryl-ester-transfer protein activities, but may increase the hepatic lipase activity.
