微小RNA在急性心肌梗死早期诊断的研究进展 总被引:1,自引:0,他引:1
心血管疾病是社会上和临床工作中遇到的常见病与多发病,严重威胁着人民群众的生命健康,急性心肌梗死是心内科日常工作中常见的心血管疾病之一,常处于危急状态,必须得到及时治疗和干预处理,否则病死率较高,留下较多并发症;因此,早期诊断心肌梗死越发紧迫和重要;微小RNA作为近年来心肌梗死生物标志物以及治疗靶点的研究热点,文章探索两者之间的关联,为今后的急性心肌梗死早期诊断研究提供借鉴。 相似文献

Stroke in children is a heterogeneous disorder. Over 100 risk factors for stroke have been reported and genetic predisposition to stroke has been established. The most frequently reported risk factors are congenital heart malformations, hemolytic anemias, collagen vascular diseases, some rare inborn metabolic disorders, trauma, infection and thrombophilia. The aim of this article is to provide an overview of investigated inherited prothrombotic risk factors in children with first ischemic stroke. Various prothrombotic risk factors have been investigated in pediatric stroke including elevated homocysteine and lipoprotein (a), antithrombin, protein C and protein S deficiency, Factor V Leiden, Factor II G20210A and plasminogen activator inhibitor-1 4G/5G polymorphism. Despite similar criteria for inclusion of different studies in meta-analyses investigating first ischemic stroke in children, the obtained results were not consistent for all prothrombotic risk factors. The discrepancies found could be explained by methodological issues like different sample sizes, patient populations included and lack of controls. In order to provide the necessary power for randomized control trials, multi-center, multi-national approaches like International Pediatric Stroke Study have been initiated with the aim to describe risk factors for childhood stroke and explore their relationship with presentation, age, geography, and infarct characteristics. Although it is evident from numerous studies that the frequency of inherited prothrombotic factors is increased in pediatric stroke, single thrombophilia does not fully explain stroke in a child as it represents only a mild risk factor. Further studies are needed, as improved understanding of underlying mechanisms will improve primary and secondary prevention of childhood stroke. 相似文献

Stroke is the third leading cause of death and foremost cause of disability. Based on studies in CAD patients, a focus has
been shifted on genetic and inflammatory markers as risk factors for stroke besides deranged lipid profile. The present study
was aimed to ascertain the role of Lipoprotein (a), C-Reactive protein (CRP) levels and lipids in patients of ischemic stroke.
The study was done in 82 subjects including 40 Computerized Tomography (CT) proven patients of ischemic stroke and 42 age
and sex matched controls. Complete biochemical parameters including lipid profile were carried out on autoanalyzer using standard
kits and reagents. Lipoprotein (a) [Lp(a)] was determined by immunoturbidimetric assay. Atherogenic indices (Total cholesterol/
HDL, LDL/HDL and Lipid Tetrad Index) were calculated using these lipid parameters. The CRP levels were measured semi-quantitatively
by latex agglutination test method. Out of 40 stroke patients, 38 had abnormalities in lipid profile (As per ATP III guidelines).
A significant difference was seen in serum cholesterol, LDL cholesterol and atherogenic indices between the patients and controls.
The difference in CRP levels in cases and control subjects was highly significant (4.78±0.72 mg/dl vs 0.76 ±0.70, p<0.001).
96.5% of patients with raised CRP had abnormal lipid levels also. CRP levels in stroke patients showed significant correlation
with total cholesterol and LDL (p<0.001), Lp (a) (p=0.002) and atherogenic indices (p<0.05). Raised CRP levels in stroke patients
were significantly associated with large territory infarcts, severe disability and poor functional outcome (p<0.05).Genetic
[Lp(a)], metabolic (deranged Lipid profile) and inflammatory factors (CRP) together are instrumental in causing cerebrovascular
arteriosclerosis leading to ischaemic stroke and can be used as important markers to identify patients at risk of severe stroke
and to institute aggressive preventive strategies. 相似文献
