Circulating microRNAs in cardiovascular diseases: from biomarkers to therapeutic targets

null

《医学前沿（英文）》 2014年第8卷第4期页码 404-418 doi: 10.1007/s11684-014-0379-2

摘要：

microRNAs (miRNAs) are a class of conserved, short, non-coding RNAs that have important and potent capacities to regulate gene expression at the posttranscriptional level. In the past several years, the aberrant expressions of miRNAs in the cardiovascular system have been widely reported, and the crucial roles of some special miRNAs in heart development and pathophysiology of various cardiovascular diseases have been gradually recognized. Recently, it was discovered that miRNAs are presented in peripheral circulation abundantly and stably. This has raised the possibility of using circulating miRNAs as biomarkers for diseases. Furthermore, some studies demonstrated that circulating miRNAs may serve as novel extracellular communicators of cell-cell communication. These discoveries not only reveal the functions of circulating miRNAs in cardiovascular system but also inform the development of miRNAs therapeutic strategies. In this review, we discuss the potential roles of circulating miRNAs in a variety of cardiovascular diseases from biomarkers to therapeutic targets to clearly understand the roles of circulating miRNAs in cardiovascular system.

Nicotinic acetylcholine receptor α7 subunit: a novel therapeutic target for cardiovascular diseases

null

《医学前沿（英文）》 2012年第6卷第1期页码 35-40 doi: 10.1007/s11684-012-0171-0

摘要：

Inflammation is important in the pathogenesis and development of cardiovascular diseases. Recent studies show that vagus nerve stimulation inhibits pro-inflammatory cytokine production through “the cholinergic anti-inflammatory pathway,” more specifically via the α7 nicotinic acetylcholine receptor (α7nAChR). In the current study, the role of the cholinergic anti-inflammatory pathway during septic shock, hypertension, and myocardial infarction is reviewed, and its possible clinical implications in cardiovascular diseases are discussed.

Multislice computed tomography angiography in the diagnosis of cardiovascular disease: 3D visualizations

Zhonghua Sun

《医学前沿（英文）》 2011年第5卷第3期页码 254-270 doi: 10.1007/s11684-011-0153-7

摘要： Multislice computed tomography (CT) has been widely used in clinical practice for the diagnosis of cardiovascular disease due to its reduced invasiveness and high spatial and temporal resolution. As a reliable alternative to conventional angiography, multislice CT angiography has been recognized as the method of choice for detecting and diagnosing head and neck vascular disease, abdominal aortic aneurysm, aortic dissection, and pulmonary embolism. In patients with suspected coronary artery disease, although invasive coronary angiography still remains as the gold standard technique, multislice CT angiography demonstrates high diagnostic accuracy; in selected patients, it is considered as the first-line technique. The imaging diagnosis of cardiovascular disease is based on a combination of two-dimensional (2D) and three-dimensional (3D) visualization tools to enhance the diagnostic value. This is facilitated by reconstructed visualizations which provide additional information about the extent of the disease, an accurate assessment of the spatial relationship between normal structures and pathological changes, and pre-operative planning and post-procedure follow-up. The aim of the present article is to present an overview of the diagnostic performance of various 2D and 3D CT visualizations in cardiovascular disease, including multiplanar reformation, maximum intensity projection, volume rendering, and virtual intravascular endoscopy. The recognition of the potential value of these visualizations will assist clinicians in efficiently using the multislice CT imaging modality for the diagnostic management of patients with cardiovascular disease.

Prevalence of cardiovascular diseases in China

Jun-Jie XIAO MD, Yi-Han CHEN MD, PhD,

《医学前沿（英文）》 2010年第4卷第1期页码 16-20 doi: 10.1007/s11684-010-0007-8

摘要： Cardiovascular diseases (CVD) cause one third of all deaths in China, and the number is anticipated to double by 2020. They also greatly result in disability and adjusted life year loss. The prevalence of CVD has become a new burden for China, due to an aging population, smoking, and changes in dietary habits and lifestyles. As the largest developing country, China needs to tailor her own national policies for managing CVD with full consideration of epidemiology, local needs, and affordability. Smoking cessation, increased physical activity, control of hypertension and hypercholesterolemia, and maintenance of a “traditional Chinese” diet should be important strategies for reducing the burden of CVD in China. Health officials in China should take their responsibilities to implement educational and preventive measures seriously.

Potential functions of esophageal cancer-related gene-4 in the cardiovascular system

Rui Zhou, Yuanshu Liu, Wenjun Huang, Xitong Dang

《医学前沿（英文）》 2019年第13卷第6期页码 639-645 doi: 10.1007/s11684-019-0701-0

摘要： Esophageal cancer-related gene-4 ( ) is cloned from the normal epithelium of the esophagus. It is constitutively expressed in quiescent epithelial cells and downregulated during tumorigenesis, and expression levels are inversely correlated with the malignant phenotype of tumor cells, validating that is a real tumor suppressor gene. Unlike other tumor suppressor genes that usually encode membrane or intracellular proteins, encodes a 148-amino acid pre-pro-peptide that is tethered on the cell surface in epithelial cells, specialized epithelial cells, and human leukocytes, where it can be processed tissue dependently into several small peptides upon cell activation. Ecrg4 is expressed in a wide variety of other cells/tissues, including cardiomyocytes and conduction system of the heart，, the glomus cells of the carotid body, adrenal glands, choroid plexus, and leukocytes among others, where it exerts distinct functions, such as promoting/suppressing inflammation, inducing neuron senescence, stimulating the hypothalamus–pituitary–adrenal axis, maintaining the stemness of stem cells, participating in the rhythm and rate control of the heart, and possibly gauging the responsiveness of the cardiovascular system (CVS) to hypoxia, in addition to tumor suppression. Here, we briefly review the latest discoveries on Ecrg4 and its underlying molecular mechanisms as a tumor suppressor and focus on the emerging roles of Ecrg4 in the CVS.

《工程（英文）》 2023年第26卷第7期页码 99-107 doi: 10.1016/j.eng.2022.12.004

摘要：

亚临床动脉粥样硬化和代谢紊乱是心血管健康的重要风险因素，应用免疫球蛋白G（IgG）N-聚糖模式作为炎症指标表征其发病风险已有研究报道。然而，对于IgG N-糖基谱在心血管疾病（CVD）风险分层中的能力仍然未知。本研究旨在利用IgG N-糖基标志物开发追踪心血管疾病风险的年龄指数。本研究基于横断面调查，从Busselton健康和老龄研究中共招募1465名40~70岁之间的个体。使用机器学习递归特征消除和惩罚回归算法逐步筛选特征糖基，并开发IgG N-糖基化心血管年龄（GlyCage）指数，以反映归因于心血管风险的与真实年龄间的偏差。结果显示，对GlyCage指数贡献最大的是具有双分叉N-乙酰葡萄糖胺（GlcNAc）的岩藻糖基化N-聚糖（GP6, FA2B）和具有双分叉GlcNAc的双半乳糖基化N-聚糖（GP13, A2BG2）。GlyCage独立于真实年龄，与较高的Framingham十年心血管风险[优势比（OR）为1.09；95% CI: 1.05~1.13]和患心血管疾病概率（OR, 1.07; 95% CI: 1.01~1.13）显著相关。GlyCage大于真实年龄三年及以上的个体，其心血管风险和心血管疾病患病概率增加，调整后的OR值分别为2.22（95% CI：1.41~3.53）和2.71（95% CI: 1.25~6.41）。GlyCage指数区分十年心血管风险和事件的ROC曲线下面积（AUC）值分别为0.73和0.65，而真实年龄为0.65和0.63。因此，本研究开发的GlyCage指数利用IgG N-糖基谱追踪心血管健康水平。GlyCage和真实年龄之间的差距能够独立地表征心血管风险，提示IgG N-糖基化在心血管疾病的发病机制中起作用。GlyCage指数对心血管风险的预测能力需要在其他人群中进行外部和纵向验证。

Poor adherence to P2Y12 antagonists increased cardiovascular risks in Chinese PCI-treated patients

null

《医学前沿（英文）》 2017年第11卷第1期页码 53-61 doi: 10.1007/s11684-017-0502-2

摘要：

Low adherence to secondary prevention medications (ATM) of patients after acute coronary syndrome (ACS) is associated with poor clinical outcomes. However, literature provides limited data on assessment of ATM and risks associated with poor in Chinese patients with ACS. In the current work, ATM was assessed in consecutively recruited patients with ACS in Tongji Hospital from November 5, 2013 to December 31, 2014. A total of 2126 patients were classified under low adherence (proportion of days covered (PDC)<50%) and high adherence (PDC>50%) groups based on their performance after discharge. All patients were followed up at the 1st, 6th, and 12th month of discharge while recording ATM and major adverse cardiac events (MACE). Bivariate logistic regression was used to identify the factors associated with ATM. Cox regression was used to analyze the association between ATM and MACE within one year after discharge. Results showed that coronary artery bypass grafting (CABG) alone had significantly lower proportion of high adherence to P2Y12 antagonists (83.0% vs. 90.7%, P<0.01) than patients treated with percutaneous coronary intervention (PCI) only. Moreover, in patients undergoing PCI, high adherence to P2Y12 antagonists decreased the risk of MACE (hazard ratio=0.172, 95% confidence interval: 0.039–0.763; P=0.021). In conclusion, PCI-treated patients are more prone to remaining adherent to medications than CABG-treated patients. High adherence to P2Y12 antagonists was associated with lower risk of MACE.

Association of metabolic syndrome with arterial compliance in children and adolescents

ZHANG Li, MI Jie, LI Ming, JIANG Benyu

《医学前沿（英文）》 2007年第1卷第1期页码 68-73 doi: 10.1007/s11684-007-0014-6

摘要： The association of metabolic syndrome (MS) with arterial compliance in children and adolescents was explored. 337 subjects (188 men and 149 women) aged 6 18 (10.95?3.01) years, out of Beijing Child Metabolic Syndrome Study , were divided into three case groups (one component, two components, three & more components of MS) and one control group based on the Cook s MS definition in children and adolescents. Measurements including anthropometry, blood pressure, fasting plasma glucose and insulin, serum lipid profile were done. Homeostasis model assessment for insulin resistance (HOMA-IR) index was calculated for estimating individual insulin resistance. Arterial compliance was measured using digital pulse wave analyzing method from the pulse trace machine (Micro medical, London), and then the stiffness index (SI) was determined. The mean value of SI in MS group was significant higher than that in control group [(7.69?1.63) vs (6.25?0.86) m/s, <0.01]. With the increase of the clustering of MS components, SI and HOMA-IR were gradually increased. After taking account of gender, age and pubertal development, the partial correlation analysis showed that the amount of components of MS and HOMA-IR were positively correlated with SI (both values were less than 0.05). The arterial compliance of MS group was significantly lowered in children and adolescents, and with the increase of the clustering of MS components, arterial compliance was gradually decreased. It was suggested that arterial compliance assessment in children and adolescents was important for early prevention of cardiovascular diseases.

Physiological functions and clinical implications of the N-end rule pathway

null

《医学前沿（英文）》 2016年第10卷第3期页码 258-270 doi: 10.1007/s11684-016-0458-7

摘要：

The N-end rule pathway is a unique branch of the ubiquitin-proteasome system in which the determination of a protein’s half-life is dependent on its N-terminal residue. The N-terminal residue serves as the degradation signal of a protein and thus called N-degron. N-degron can be recognized and modifed by several steps of post-translational modifications, such as oxidation, deamination, arginylation or acetylation, it then polyubiquitinated by the N-recognin for degradation. The molecular basis of the N-end rule pathway has been elucidated and its physiological functions have been revealed in the past 30 years. This pathway is involved in several biological aspects, including transcription, differentiation, chromosomal segregation, genome stability, apoptosis, mitochondrial quality control, cardiovascular development, neurogenesis, carcinogenesis, and spermatogenesis. Disturbance of this pathway often causes the failure of these processes, resulting in some human diseases. This review summarized the physiological functions of the N-end rule pathway, introduced the related biological processes and diseases, with an emphasis on the inner link between this pathway and certain symptoms.
