Leucine dehydrogenase (LeuDH) is a promising enzyme for the industrial production of L-tert-leucine (L-Tle), but its catalytic activity toward trimethylpyruvate (TMP) requires enhancement. In this study, we employed a semi-rational design approach involving homology modeling of LeuDH from Exiguobacterium sibiricum (EsiLeuDH) and molecular docking with TMP to predict potential mutation sites. These sites were tested using an alanine scanning strategy to assess their impact on enzymatic activity, followed by site-saturation mutagenesis and iterative saturation mutagenesis.

Article Synopsis
  • * The study analyzed data from over 1 million participants aged 35-75 across 453 districts and found a notable increase in mortality risk associated with low area-level SES, especially among older adults, women, and those with low individual SES.
  • * The research reveals that both area-level and individual-level SES are important determinants of health, suggesting that improving community resources could help reduce mortality disparities.

Background: The predictive value of Life's Crucial 9 (LC9), a recently proposed cardiovascular health risk score combining psychological health and Life's Essential 8 (LE8), remains unclear.

Methods And Results: In this cohort study, we included 16 290 adults without cardiovascular disease from the 2007 to 2018 cycles of NHANES (National Health and Nutrition Examination Survey). The LC9 was the mean of the LE8 score and the depression score, which represented a dimension of psychological health.

Article Synopsis
  • - The study examines the effectiveness of different antihypertensive drug classes in improving NT-proBNP levels and reducing cardiovascular risks in patients with pre-heart failure (pre-HF) hypertension, using data from the SPRINT trial.
  • - Among 3,293 pre-HF hypertensive patients, thiazide-type diuretics showed a higher chance of NT-proBNP improvement and a lower risk for heart failure (HF), while ACEI/ARB drugs had a protective effect on primary cardiovascular outcomes.
  • - In contrast, beta-blockers were linked to a decreased likelihood of NT-proBNP improvement and an increased risk of HF and adverse outcomes, suggesting that thiazide-type diuretics and ACEI/ARB

Background: The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.

Methods: A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included.

There is no reliable causal evidence for the effect of statins on diabetic nephropathy (DN) and diabetic retinopathy (DR), and the results of previous observational studies are contradictory. Genetic variants linked to low-density lipoprotein cholesterol (LDL-C) from a UK biobank genome-wide association study and located within a 100kb window around HMGCR were used to proxy statins, comparing with PCSK9 inhibitors (control). DN and DR genome-wide association study summary statistics were obtained from the FinnGen study.

Background: Uncertainty exists about whether lowering systolic blood pressure to less than 120 mm Hg is superior to that of less than 140 mm Hg, particularly in patients with diabetes and patients with previous stroke.

Methods: In this open-label, blinded-outcome, randomised controlled trial, participants with high cardiovascular risk were enrolled from 116 hospitals or communities in China. We used minimised randomisation to assign participants to intensive treatment targeting standard office systolic blood pressure of less than 120 mm Hg or standard treatment targeting less than 140 mm Hg.

Background: Heart failure with preserved ejection fraction is a major global public health problem, while effective risk stratification tools are still lacking. We sought to construct a multi-mRNA signature to predict 1-year all-cause death.

Methods: We selected 30 patients with heart failure with preserved ejection fraction who died during 1-year follow-up and 30 who survived in the discovery set.

Context: Iron is an essential element in the human body and plays a critical role in many physiological and cellular processes. However, the association between iron status and the risk of all-cause or cause-specific mortality has not been well-investigated. And it is unclear whether the association between iron metabolic biomarkers and the risk of mortality differs between people with and without diabetes mellitus (DM).

Background: Hypertension management in China is suboptimal with high prevalence and low control rate due to various barriers, including lack of self-management awareness of patients and inadequate capacity of physicians. Digital therapeutic interventions including mobile health and computational device algorithms such as clinical decision support systems (CDSS) are scalable with the potential to improve blood pressure (BP) management and strengthen the healthcare system in resource-constrained areas, yet their effectiveness remains to be tested. The aim of this report is to describe the protocol of the Comprehensive intelligent Hypertension managEment SyStem (CHESS) evaluation study assessing the effect of a multifaceted hypertension management system for supporting patients and physicians on BP lowering in primary care settings.

Background And Aims: Personalized antihypertensive drug selection is essential for optimizing hypertension management. The study aimed to develop a machine learning (ML) model to predict individual blood pressure (BP) responses to different antihypertensive medications.

Methods And Results: We used data from a pragmatic, cluster-randomized trial on hypertension management in China.

Background: Postprocedural anticoagulation (PPA) is frequently administered after primary percutaneous coronary intervention in ST-segment-elevation myocardial infarction, although no conclusive data support this practice.

Methods: The RIGHT trial (Comparison of Anticoagulation Prolongation vs no Anticoagulation in STEMI Patients After Primary PCI) was an investigator-initiated, multicenter, randomized, double-blind, placebo-controlled, superiority trial conducted at 53 centers in China. Patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention were randomly assigned by center to receive low-dose PPA or matching placebo for at least 48 hours.

Background: High-density lipoprotein cholesterol (HDL-C) has been inversely associated with cardiovascular disease (CVD) risk, but recent evidence suggests that extremely high levels of HDL-C are paradoxically related to increased CVD incidence and mortality. This study aimed to comprehensively examine the associations of HDL-C with all-cause and cause-specific mortality in a Chinese population.

Methods: The China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) project included 3,397,547 participants aged 35-75 years with a median follow-up of 3.

Objective: To examine the joint association of healthy lifestyles and statin use with all-cause and cardiovascular mortality in high-risk individuals, and evaluate the survival benefits by life expectancy.

Methods: During 2015-2021, participants aged 35-75 years were recruited by the China Health Evaluation And risk Reduction through nationwide Teamwork. Based on number of healthy lifestyles related to smoking, alcohol drinking, physical activity, and diet, we categorized them into: very healthy (3-4), healthy (2), and unhealthy (0-1).

The health significance of triglyceride-rich lipoproteins, also known as remnant cholesterol, has been increasingly recognized. However, evidence of their associations with cause-specific mortality in the general population was previously insufficient. To explore these associations and their heterogeneities across subgroups, a prospective cohort study was conducted including 3,403,414 community-based participants from ChinaHEART, an ongoing government-funded public health program throughout China, from November 2014 through December 2022.

Introduction: Exploring sociodemographic effect modification is important to provide evidence for developing targeted recommendations and reducing health inequalities. This study evaluated how sociodemographic factors including age, sex, race/ethnicity and socioeconomic status (SES) modify the association between leisure-time physical activity (LTPA) and all-cause and major cause-specific mortality.

Methods: The study sample included 471,992 people from the 1997-2018 National Health Interview Survey (NHIS) and 41,830 people from the 1999-2018 National Health and Nutrition Examination Survey (NHANES).
