Introduction: Acute coronary syndrome is often the first event of coronary disease of young subjects. Objective: To study sociodemographic, clinical, paraclinical, therapeutic and evolutionary aspects of acute coronary syndrome of young subjects. Patients and Methods: Descriptive cross-sectional study with prospective recruitment from October 01, 2020 to March 31, 2022. Were included all patients admitted for acute coronary syndrome whose age was less or equal to 45 years and who had undergone coronary angiography at the Mother-Child University Hospital on Luxembourg from Bamako. Results: During the study period, we collected 60 patient files out of 198. These 60 patient files met our inclusion criteria. Hospital frequency was 30.30%. Average age of patients was 40.43 ± 3.9 years. Sex ratio M/F was 5.3. Main cardiovascular risk factor was smoking tobacco (23.42%), followed by dyslipidemia (13.92%). Functional signs were dominated by angina 62% followed by dyspnea 25.3%. Persistent ST-segment elevation on electrocardiogram was present in 76.4%. Left ventricular systolic dysfunction was present in 26.5%. Time to first medical contact was more than 12 hours in 62.7% of cases. Radial approach was adopted in 94% of cases. Coronary angiography was pathological in 85% (n = 51) of cases. Lesions were single-vessel disease in 47.1% and culprit artery was anterior interventricular in 51% of cases. Dual anti-platelet aggregation was aspirin and ticagrelor in 91.8% of cases. Angioplasty was performed in all patients who had significant abnormalities at coronary angiography. In-hospital mortality was 3.9%. Conclusion: Acute coronary syndromes exist in young Africans with a male predominance. Main cardiovascular risk factor is smoking tobacco. Coronary lesions are single vessel disease in the majority of case. Most of patients meet medical team after 12 hours. Time to first medical contact is a main challenge in our country.

L-Ergothioneine ameliorates MPTP-induced Parkinson's disease in C57BL/6J mice by activating DJ-1

引用

Food Science and Human Wellness 2024年

作者： Xianshe Meng# Huawen Meng# Shuzeng Hou Zequn Yin Xuerui Wang Ke Gong Feng Zhang Qingshan Li Shuang Zhang Yuanli Chen Xiaoxiao Yang Zhiwei Zhao Chenzhong Liao Yajun Duan Department of cardiology， the First Affiliated Hospital of USTC， Division of Life Sciences and Medicine， University of Science and Technology of China Key Laboratory of Metabolism and Regulation for Major Diseases of Anhui Higher Education Institutes， Hefei University of Technology

Parkinson’s disease (PD) is one of the most common neurodegenerative diseases. The loss of dopaminergic (DAergic) neurons in the substantia nigra and the decrease of dopamine (DA) levels accelerate the process of PD. L-Ergothioneine (EGT) is a natural antioxidant derived from microorganisms， especially in edible mushrooms. EGT can penetrate blood-brain barrier and its levels are significantly decreased in the plasma of PD patients. Therefore， we speculated that EGT could ameliorate PD， and determined its effect on PD development by using 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine (MPTP)-induced PD mouse models and neurotoxin 1-methyl-4-phenylpyridinium (MPP+)-induced cell models. Our results show that EGT alleviated MPTP-induced behavioral dysfunction in mice. Mechanistically， we innovatively revealed that EGT is a key regulator of DJ-1. EGT restored DA levels by activating the DJ-1-Nuclear receptor-related factor 1(Nurr1) axis. Furthermore， it reduced reactive oxygen species (ROS) levels by regulating the DJ-1-Nuclear factor erythroid 2-related factor 2 (Nrf2) pathway， which inhibited oxidative stress-induced DAergic neuronal apoptosis. Combined treatment with DJ-1-siRNA transfection revealed that blocking DJ-1 reversed EGT upregulated Nurr1 and Nrf2 expression in the nucleus， which significantly decreased the benefits of EGT. Taken together， our study suggests that EGT can ameliorate PD and be considered as a strategy for PD treatment.
