Background: Most deaths from coronary artery disease (CAD) are due to acute myocardial infarction (AMI). There is an urgent need for early AMI detection, particularly in patients with stable CAD. 5-methylcytosine (5mC) regulatory genes have been demonstrated to involve in the progression and prognosis of cardiovascular diseases, while little research examined 5mC regulators in CAD to AMI progression.

Department of Interventional Radiology and Vascular, The Affiliated Hospital of Guangzhou Medical University, Guangzhou Women and Children's Medical Center, Guangzhou 510060, China. Electronic address:

Retinoblastoma is a most frequently occurring primary intraocular tumor in infancy and children, highlighting the requirement to find and develop novel and more effective therapeutic approaches. Wedelolactone (WDL), a nature compound isolated from E. prostrata, exhibits multiple biological activities through regulating various signaling pathways; however, its potential influences on retinoblastoma progression are still unknown, and thus was investigated in our study, as well as the underlying mechanisms.

Mitochondrial FAD shortage in SLC25A32 deficiency affects folate-mediated one-carbon metabolism.

Cell Mol Life Sci

June 2022

Department of Genetics and Endocrinology, Guangzhou Women and Children's Medical Center, the Affiliated Hospital of Guangzhou Medical University, 9 Jinsui Road, Guangzhou, China.

Article Synopsis
  • The study focuses on SLC25A32 dysfunction, which is linked to neural tube defects (NTDs) and exercise intolerance, but lacks sufficient animal models for understanding specific disease mechanisms.
  • Researchers created various genetically modified mice to replicate human mutations, finding that certain mutations caused mild motor issues and biochemical disturbances while leading to NTDs in others.
  • Results revealed that SLC25A32 dysfunction blocked the uptake of flavin adenine dinucleotide (FAD) in mitochondria, disrupted crucial metabolic processes, and suggested that formate supplementation could alleviate certain deficiencies and NTDs in affected embryos.

Objective: The current study was to design a cardiovascular risk score for the diagnosis of coronary heart disease (CHD) in the rural area of China and the sensitivity and specificity of this score would be assessed.

Methods: A total of 520 patients were enrolled and based on the results from coronary artery angiography, patients were divided into three groups: CHD group (coronary artery ≥50% stenosis), atherosclerosis group (coronary artery <50% stenosis) and normal groups (without stenosis). Between-group differences were evaluated and the sensitivity and specificity of cardiovascular risk score were evaluated.

Subthreshold depression is a highly prevalent condition in adolescents who are at high risk for developing major depressive disorder. In preclinical models of neurological and psychiatric diseases, Lycium barbarum polysaccharide (LBP) extracted from Goji berries had anti-depressant effects including but not limited to anti-oxidative and anti-inflammatory properties. However, the effect of LBP on subthreshold depression is unclear.

Background: Animal and human studies have revealed reciprocal association between exercise and gut-brain axis. However, the clinical evidence from randomized controlled trials (RCT) are still limited to directly assess the effects of aerobic exercise on gut microbiota. To fill this gap, we conducted this 12-week RCT in both groups of adolescents with and without sub-threshold mood symptoms.

Department of Interventional Radiology, Guangdong Provincial People's Hospital, Guangdong Academy of Medical Sciences, Guangzhou, China.

Introduction: Intra-arterial chemotherapy (IAC) has been used successfully for unilateral and bilateral eye disease with advanced or less advanced intraocular disease and of children as young as 3 months of age. In this study, we expanded the use of IAC to eyes of two infants with very low birthweight (birth weight of 1000-1500 g) and retinoblastoma.

Patient Concerns: The ophthalmologists refused to give patients intravenous chemotherapy (IVC), considering the risk of IVC because of the low body weight.

The majority of antidepressant medication trials have focused on adult populations (ages 18-65), with much less research in older and younger populations. Moreover, key differences in the efficacy and safety of antidepressants have been identified between these age groups. Ketamine has emerged as a promising new treatment for treatment resistant depression (TRD).

Patients with Bipolar Disorder (BD) are associated with aberrant uncinate fasciculus (UF) that connects amygdala-ventral prefrontal cortex (vPFC) system, but the casual relationship is still uncertain. The research aimed to investigate the integrity of UF among offspring of patients with BD and investigate its potential causal association with subsequent declaration of BD. The fractional anisotropy (FA) and mean diffusivity (MD) of UF were compared in asymptomatic offspring (AO, n = 46) and symptomatic offspring (SO, n = 45) with a parent with BD, and age-matched healthy controls (HCs, n = 35).

Decrement in processing speed (PS) is a primary cognitive morbidity in clinical populations and could significantly influence other cognitive functions, such as attention and memory. Verifying the usefulness of connectome-based models for predicting neurocognitive abilities has significant translational implications on clinical and aging research. In this study, we verified that resting-state functional connectivity could be used to predict PS in 99 older adults by using connectome-based predictive modeling (CPM).

  • The study compares in-hospital outcomes of patients with left ventricular myocardial infarction (LVMI) who also have right ventricular myocardial infarction (RVMI) versus those who do not.
  • Patients with RVMI are generally more likely to be male, have higher body mass index, elevated inflammatory markers, and other health issues like diabetes and dyslipidemia.
  • Those with RVMI experience worse heart function, shown by lower ejection fractions and higher pulmonary artery pressure, and they face higher risks of in-hospital mortality and acute heart failure compared to those without RVMI.

Neuro-inflammation might impact on clinical manifestations and cognition function via changing the volumes of key brain structures such as the anterior cingulate cortex (ACC) in bipolar disorder (BD). In this study, we investigated the interrelations among interleukin (IL)-6 cytokine level, grey matter (GM) volume of the anterior cingulated cortex (ACC), and attention function among offspring of parents diagnosed with BD. The offspring were categorized as being either asymptomatic or symptomatic based on whether they manifested pre-defined sub-threshold mood symptoms.
