Abstract
BACKGROUND Previous studies have reported lipoprotein(a) was related to increased risk of ischemic stroke. However, the role of fibrinogen in their associations was not fully elucidated. AIM We aimed to investigate the mediating role of fibrinogen in the association between lipoprotein(a) and risk of ischemic stroke. METHODS A total of 516 patients with ischemic stroke were matched 1:1 to patients without ischemic stroke for age and gender. Serum lipoprotein(a) and plasma fibrinogen levels were collected on the basis of the results of biochemical tests. Multivariate conditional logistic regression analyses were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for lipoprotein(a) levels and ischemic stroke risk. Mediation analysis were further conducted to evaluate the potential mediating role of fibrinogen in the association between lipoprotein(a) and ischemic stroke risk. RESULTS The lipoprotein(a) level of subjects with ischemic stroke was significantly higher than that of subjects without ischemic stroke (P < 0.001). Each SD increment of lipoprotein(a) was associated with 27% higher odds (OR 1.27, 95%CI: 1.11, 1.45) increment in ORs of ischemic stroke. Furthermore, mediation analyses indicated that fibrinogen mediated 10.15% of the associations between lipoprotein(a) and ischemic stroke. CONCLUSIONS Higher level of lipoprotein(a) was independently associated with increased risk of ischemic stroke and fibrinogen partially mediated the associations of lipoprotein(a) and ischemic stroke risk.

Abstract
The predictive ability of coronary heart disease (CHD) and ischemic stroke (IS) polygenic risk scores (PRS) have been evaluated individually, but whether they predict the combined outcome of atherosclerotic cardiovascular disease (ASCVD) remains insufficiently researched. It is also unclear whether associations of the CHD and IS PRS with ASCVD are independent of subclinical atherosclerosis measures. 7,286 White and 2,016 Black participants from the population-based Atherosclerosis Risk in Communities study who were free of cardiovascular disease and type 2 diabetes at baseline were included. We computed previously validated CHD and IS PRS consisting of 1,745,179 and 3,225,583 genetic variants, respectively. Cox proportional hazards models were used to test the association between each PRS and ASCVD, adjusting for traditional risk factors, ankle-brachial index, carotid intima media thickness, and carotid plaque. The hazard ratios (HR) for the CHD and IS PRS were significant with HR of 1.50 (95% CI: 1.36-1.66) and 1.31 (95% CI: 1.18-1.45) respectively for the risk of incident ASCVD per standard deviation increase in CHD and IS PRS among White participants after adjusting for traditional risk factors. The HR for the CHD PRS was not significant with an HR of 0.95 (95% CI: 0.79-1.13) for the risk of incident ASCVD in Black participants. The HR for the IS PRS was significant with an HR of 1.26 (95%CI: 1.05-1.51) for the risk of incident ASCVD in Black participants. The association of the CHD and IS PRS with ASCVD was not attenuated in White participants after adjustment for ankle-brachial index, carotid intima media thickness, and carotid plaque. The CHD and IS PRS do not cross-predict well, and predict better the outcome for which they were created than the composite ASCVD outcome. Thus, the use of the composite outcome of ASCVD may not be ideal for genetic risk prediction.

Abstract
A 5-year-old female patient presented to the emergency room with right upper limb weakness, inability to speak and left side deviation of the mouth. Computed tomography (CT) scan was done and she was diagnosed with ischemic stroke. During her medical evaluation she was found to have high blood pressure (186/104 mm Hg). Investigations done to evaluate for secondary causes of hypertension and stroke revealed that she has inherited thrombophilia and abdominal aortic coarctation. Balloon angioplasty was done that lowered her elevated blood pressure, which was not responding well to antihypertensive medications, to near normal value for her age. MAS is a very rare condition, characterized by narrowing of distal thoracic aorta or abdominal aorta. Pediatric Patients can have a stroke due to a rare underlying condition. The patient reported had a contellation of two conditions, inherited thromophilia and MAS.

Abstract
Atherosclerotic cardiovascular diseases (ASCVD), including coronary artery disease, cerebrovascular disease, and peripheral arterial disease, represent a significant cause of premature death worldwide. Biomarkers, the evaluation of which would allow the detection of ASCVD at the earliest stage of development, are intensively sought. Moreover, from a clinical point of view, a valuable biomarker should also enable the assessment of the patient’s prognosis. It has been known for many years that the concentration of fibrinogen in plasma increases, inter alia, in patients with ASCVD. On the one hand, an increased plasma fibrinogen concentration may be the cause of the development of atherosclerotic lesions (increased risk of atherothrombosis); on the other hand, it may be a biomarker of ASCVD, as it is an acute phase protein. In addition, a number of genetic polymorphisms and post-translational modifications of fibrinogen were demonstrated that may contribute to the risk of ASCVD. This review summarizes the current data on the importance of fibrinogen as a biomarker of ASCVD, and also presents the relationship between molecular modifications of this protein in the context of ASCVD.

Abstract
BACKGROUND CTNNB1 is reported to be related to the pathological process of ischemic stroke (IS) and coronary artery disease (CAD). Polymorphism located in the 3' untranslated region (3'UTR) of a gene might affect gene expression by modifying binding sites for microRNAs (miRNAs). This study aimed to analyze the association between polymorphism rs2953, which locates in the 3'UTR of CTNNB1, and the risk of IS and CAD. METHODS The CTNNB1 messenger RNA (mRNA) expression level in peripheral venous blood was measured. In total, 533 patients with IS, 500 patients with CAD, and 531 healthy individuals were genotyped by Sequenom Mass-Array technology. The binding of miR-3161 to CTNNB1 was determined by dual-luciferase reporter assay. RESULTS The CTNNB1 mRNA expression level for the IS group was significantly lower than that for the control group. Rs2953 was significantly associated with both IS risk and CAD risk. Significant association was also found between polymorphism rs2953 and many conventional factors, such as serum lipid level, blood coagulation markers, blood glucose level, and homocysteine level in patients. Rs2953 T allele introduced a binding site to miRNA-3161 and thus decreased luciferase activity. CONCLUSION Polymorphism rs2953 is associated with the risk of both IS and CAD. Moreover, polymorphism rs2953 (T) introduces a binding site to miRNA-3161 and thus decreases luciferase activity in cell lines.

Abstract
Introduction Intraoperative thrombosis of saphenous veins (SV) during open harvesting is very rare. Case Report We present a case of a 60-year-old male patient with multivessel coronary artery disease and a history of a non-ST elevation acute coronary syndrome, and type-2 diabetes mellitus admitted for coronary artery bypass grafting, in whom bilateral intraoperative SV thrombosis occurred during graft harvesting. Routine thrombophilia screening showed no abnormalities and cancer was excluded. Compared with healthy controls, we observed prolonged fibrin clot lysis time and increased thrombin generation reflected by endogenous thrombin potential. Scanning electron microscopy of the thrombosed material revealed compact and thick fibrin layer on the clot surface with a solid mass of unusually compressed platelets and erythrocytes underneath. The patient was tested for fibrinogen and factor (F) XIII polymorphisms, and was found to be heterozygous for β-fibrinogen HaeIII (-455G > A) and FXIII Val34Leu (100G > T). Conclusion β-fibrinogen HaeIII and FXIII Val34Leu polymorphisms are reflected in reduced clot permeability and susceptibility to lysis, and might contribute to intraoperative SV thrombosis during vascular grafting procedures. Carriers of those are at risk of primary venous graft failure after bypass procedures.

Abstract
Background and Objective: The aim of present study was to compare, and determine, the effects of a modified alternate-day fasting diet vs. calorie restriction on inflammatory indices and coagulation factors. Methods: This was a randomized clinical trial consisting of 80 metabolic syndrome patients, who were enrolled and randomly dichotomized into a modified alternate-day fasting diet or calorie restriction group for 4 months. We measured weight, body mass index (BMI), waist circumstance (WC), waist-hip-ratio (WHR) and fat mass as primary outcomes and assessed high sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and coagulation factors levels as secondary outcomes before and after intervention. Results: Compared to the calorie restriction diet, following a modified alternate-day fasting diet led to a greater reduction in body weight (kg) (-6.43 ± 4.34 vs -4.11 ± 4.27; P = 0.02), BMI (kg/m2) (-3.19 ± 2.90 vs -1.43 ± 2.72; P = 0.01), fat mass (kg) (-4.88 ± 2.09 vs -3.72 ± 2.43; P = 0.03), WC (cm) (-5.57 ± 5.64 vs -2.32 ± 5.95; P = 0.01) and WHR (-0.05 ± 0.06 vs -0.02 ± 0.07; P = 0.04). Furthermore, a greater change was found in hs-CRP levels (mg/L) (-2.06 ± 1.18 vs -0.97 ± 0.82; P = 0.03), prothrombin time (s) (1.41 ± 2.34 vs -0.41 ± 2.17; P < 0.001), activated partial thromboplastin time (s) (0.26 ± 3.70 vs -1.78 ± 3.56; P = 0.04) in modified alternate-day fasting diet when compared to calorie restriction diet. However, there was no difference in TNF-α or IL-6 and fibrinogen between groups (P > 0.05). Conclusions: These findings suggest that a modified alternate-day fasting diet can be a beneficial alternative for the management of body weight, fat mass and WC as well as hs-CRP and coagulation factors levels among metabolic syndrome patients.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a multifactorial disease in which genetic and acquired risk factors may contribute to disease pathogenesis. Several studies have demonstrated that β-fibrinogen (FGB) polymorphisms are associated with the risk of VTE. However, the results of these studies were not totally consistent. In this paper, we performed a meta-analysis to further investigate the relationship between FGB polymorphisms and susceptibility to VTE. METHODS To identify studies pertinent to the focused question, the following databases were systematically searched: PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure, and Wanfang Data. The strength of correlations was evaluated by calculating pooled odds ratios (ORs) and 95% confidence intervals (95% CIs). Subgroup analyses stratified by ethnicity, type of disorders, and source of control were also performed. RESULTS Overall, A total of 18 relevant case-control studies met the inclusion criteria and were incorporated in this meta-analysis, involving 3033 VTE cases and 4547 healthy controls. FGB -455G>A polymorphism and -148C>T polymorphism were not significantly associated with susceptibility to VTE in overall populations. However, results of stratified analysis demonstrated that among Caucasian population, the -455G>A mutation was negatively associated with the risk of VTE under all genetic comparison models (A:G OR = 0.80 95% CI = 0.70-0.91; GA + AA:GG OR = 0.80 95% CI = 0.68-0.93; GA:GG OR = 0.84 95% CI = 0.71-0.98; AA:GG + GA OR = 0.61 95% CI = 0.43-0.87; AA:GG OR = 0.57 95% CI = 0.40-0.82), which indicates FGB -455G>A polymorphism may be a protective factor for VTE. There was no correlation between -148C>T polymorphism and susceptibility to VTE in all subgroup analyses. CONCLUSION FGB -455G>A polymorphism was associated with a decreased risk of VTE among the Caucasian population.

Abstract
BACKGROUND Alzheimer's disease is a progressive, irreversible neurodegenerative disorder characterized by loss of memory and cognitive skills. More than 90% of cases are sporadic and have later age of onset. Many studies have shown a genetic predisposition for late onset Alzheimer's disease (LOAD). The most studied genetic predisposition factor is apolipoprotein E gene besides other susceptibility genes involved in vascular pathologies, homocysteine metabolism, and neuronal growth and differentiation such as methylenetetrahydrofolate reductase (MTHFR), angiotensin-converting enzyme (ACE), APOB and brain derived neurotrophic factor (BDNF). METHODS In this study Factor V Leiden (G1691A) and H1299R, prothrombin G20210A, Factor XIII V34L, B-fibrinogen -455G>A, PAI-1 5G/4G, HPA1 b/a, MTHFR C677T, MTHFR A1298C, APOE, ACE I/D, BDNF C270T and G196A polymorphisms were evaluated in 100 LOAD patients and 100 age matched healthy controls. RESULTS APOE4 allele, MTHFR CCA1298C and BDNF TTC270T genotypes were significantly higher in LOAD patients compared to the control group (p < 0.001, p = 0.04, p = 0.03, respectively). There were no significant associations between other genotypes and allele frequencies. Mini-Mental State Examination (MMSE) scores and age at onset of the patients were also evaluated for each and combined genotypes. Age at onset was significantly lowered by about approximately 4 and 5 years in patients carrying BDNF TTC270T and MTHFR TTC677T genotypes, respectively. CONCLUSION APOE, MTHFR A1298C and BDNF C270T polymorphisms may be associated with LOAD and BDNF and MTHFR alleles may play a role in the age at onset of the LOAD.

Abstract
Background It is difficult to distinguish benign pulmonary nodules (PNs) from malignant PNs by conventional examination. Therefore, novel biomarkers that can identify the nature of PNs are needed. Exosomes have recently been identified as an attractive alternative approach since tumor-specific molecules can be found in exosomes isolated from biological fluids. Methods Plasma exosomes were extracted via the exoEasy reagent method. The major proteins from plasma exosomes in patients with PNs were identified via labelfree analysis and screened for differentially expressed proteins. A GO classification analysis and KEGG pathway analysis were performed on plasma exosomal protein from patients with benign and malignant PNs. Results Western blot confirmed that protein expression of CD63 and CD9 could be detected in the exosome extract. Via a search of the human Uniprot database, 736 plasma exosome proteins from patients with PNs were detected using high-confidence peptides. There were 33 differentially expressed proteins in the benign and malignant PNs. Of these, 12 proteins were only expressed in the benign PNs group, while 9 proteins were only expressed in the malignant PNs group. We further obtained important information on signaling pathways and nodal proteins related to differential benign and malignant PNs via bioinformatic analysis methods such as GO, KEGG, and String. Conclusions This study provides a new perspective on the identification of novel detection strategies for benign and malignant PNs. We hope our findings can provide clues for the identification of benign and malignant PNs.

Abstract
Genetic variants are associated with altered clinical outcome of patients with sepsis and cardiovascular diseases. Common gene signaling pathways may be involved in the pathophysiology of these diseases. A better understanding of genetic commonality among these diseases may enable the discovery of important genes, signaling pathways, and therapeutic targets for these diseases. We investigated the common genetic factors by a systematic search of the literature. Twenty-four genes (ADRB2, CD14, FGB, FV, HMOX1, IL1B, IL1RN, IL6, IL10, IL17A, IRAK1, MASP2, MBL, MIR608, MIF, NOD2, PCSK9, PPARG, PROC, SERPINE1, SOD2, SVEP1, TF, TIRAP, TLR1) were extracted as reported genetic variations associated with altered outcome of both sepsis and cardiovascular diseases. Of these genes, the adverse allele (or combinations) was same in nine (ADRB2, FV, HMOX1, IL6, MBL, MIF, NOD2, PCSK9, SERPINE1), and the effect appears to be in the same direction in both sepsis and cardiovascular disease. Shared gene signaling pathways suggest that these are true biological results and could point to overlapping drug targets in sepsis and cardiovascular disease.

Abstract
Salvia miltiorrhiza, known as Danshen, has attracted worldwide interest for its substantial effects on coronary heart disease (CHD). Danshensu (DSS) is one of the main active ingredients of Danshen on CHD. Although it has been proven to have a good clinical effect on CHD, the action mechanisms remain elusive. In the current study, a coexpression network-based approach was used to illustrate the beneficial properties of DSS in the context of CHD. By integrating the gene expression profile data and protein-protein interactions (PPIs) data, two coexpression protein interaction networks (CePIN) in a CHD state (CHD CePIN) and a non-CHD state (non-CHD CePIN) were generated. Then, shared nodes and unique nodes in CHD CePIN were attained by conducting a comparison between CHD CePIN and non-CHD CePIN. By calculating the topological parameters of each shared node and unique node in the networks, and comparing the differentially expressed genes, target proteins involved in disease regulation were attained. Then, Gene Ontology (GO) enrichment was utilized to identify biological processes associated to target proteins. Consequently, it turned out that the treatment of CHD with DSS may be partly attributed to the regulation of immunization and blood circulation. Also, it indicated that sodium/hydrogen exchanger 3 (SLC9A3), Prostaglandin G/H synthase 2 (PTGS2), Oxidized low-density lipoprotein receptor 1 (OLR1), and fibrinogen gamma chain (FGG) may be potential therapeutic targets for CHD. In summary, this study provided a novel coexpression protein interaction network approach to provide an explanation of the mechanisms of DSS on CHD and identify key proteins which maybe the potential therapeutic targets for CHD.

Abstract
Myocardial infarction (MI) is the leading cause of fatality worldwide. Our study aimed to investigate the dysregulated long non-coding RNA (lncRNA) in MI and elucidate the mechanism of it in MI. The lncRNA and mRNA expression profiling of the whole left ventricular tissue of MI mice model (8 mice) and Sham group (8 mice) was obtained based on microarray analysis. Differentially expressed lnRNAs/mRNA (DELs/DEMs) were identified in MI. DELs/DEMs co-expression network construction, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis were conducted to predict the biological functions of DEMs. Quantitative real-time polymerase chain reaction (qRT-PCR) was subjected to validate the abnormally expressed DELs in left ventricular tissues of MI mice model. Total of 168 DELs (37 up- and 131 down-regulated) and 126 DEMs (87 up- and 39 down-regulated) were identified in MI compared with Sham group. The co-expression network of candidate DELs and DEMs was constructed, which covered 219 nodes and 1775 edges. The qRT-PCR validation results indicated that ENSMUST00000124047 was significantly down-regulated in MI group and AK166279 was significantly up-regulated in MI group. ENSMUST00000121611 and NR_015515 had the up-regulated tendency in MI group compared with Sham group. The DEMs in MI were significantly enriched in 41 signaling pathways including complement and coagulation cascades, cytokine-cytokine receptor interaction and chemokine signaling pathway. The expression profiling of dysregulated DELs in MI was identified. Our results might provide useful information for exploring the pathogenesis mechanism of MI.

Abstract
BACKGROUND Ischemic stroke (IS) is a leading cause of death and disability worldwide. As genetic heritability for IS is estimated at about 35%-40%, the identification of genetic variants associated with IS risk is of great importance. The main objective of this study was to carry out a meta-analysis for polymorphisms in CRP, EPHX2, FGA, and NOTCH3 genes and the risk for IS. METHODS Literature search for 6 candidate polymorphisms and IS was conducted using HuGE Navigator, PubMed, and Google Scholar databases. Meta-Analyst program was used to calculate pooled odds ratios (ORs) with a random effects model. RESULTS Twenty-five published studies for 6 candidate polymorphisms were included: CRP-rs1800947 (5 studies), CRP-rs1205 (3 studies), EPHX2-rs751141 (5 studies), FGA-rs6050 (6 studies), NOTCH3-rs3815188 (3 studies), and NOTCH3-rs1043994 (3 studies), for a total number of 7,825 IS cases and 56,532 control subjects. We did not find significant pooled ORs (P values > .05) for any of the genetic variants evaluated in this work. CONCLUSIONS Our meta-analysis results did not show significant associations between these 6 polymorphisms in 4 candidate genes and IS, despite the functional role of some of these single nucleotide polymorphisms (e.g., rs6050 in FGA gene). Future studies are needed to identify additional main genetic risk factors for IS in different populations.

Abstract
BACKGROUND Previous studies have investigated the association between a polymorphism (-455 G>A) in the β-fibrinogen gene and the risk of cerebral infarction. However, these results are controversial. To shed light on these inconclusive findings, we performed a meta-analysis of studies relating the β-fibrinogen genetic polymorphism (-455 G>A) to the risk of cerebral infarction. METHODS We identified literature published before July 2013 by searching PubMed, EMBASE, ISI Web of Science, the Chinese National Knowledge Infrastructure database (CNKI) and the Wanfang database in China and by reviewing the references of retrieved articles. We included studies that reported odds ratio (OR) with 95% confidence interval (CI) for the association between the β-fibrinogen genetic polymorphism and cerebral infarction risk. Publication bias was tested by a funnel plot, and the OR of all studies were combined dependent on the results of the heterogeneity tests among the individual studies. The software Review Manager (Version 5.2) was used for meta-analysis. RESULTS Twenty independent case-control studies containing 9477 subjects were included. Our results showed that the -455 G>A polymorphism in the β-fibrinogen gene was associated with the increased risk of cerebral infarction [(AA+GA) vs. GG, OR=1.17, 95%CI: 1.04-1.31, p=0.008; A vs. G, OR=1.12, 95%CI: 1.01-1.23, p=0.03] in the Chinese population by a meta-analysis. However, we did not find this association in the Caucasian population [(AA+GA) vs. GG, OR=0.99, 95%CI: 0.87-1.11, p=0.84; A vs. G, OR=0.97, 95%CI: 0.84-1.13, p=0.73, respectively]. CONCLUSION The results of our meta-analysis indicate that the -455 G>A polymorphism in the β-fibrinogen gene is a susceptibility marker of ischemic cerebral infarction in the Chinese population.

Abstract
Fibrinogen is cleaved by thrombin to fibrin, which provides the blood clot with its essential structural backbone. As an acute phase protein, the plasma levels of fibrinogen are increased in response to inflammatory conditions. In addition to fibrinogen levels, fibrin clot structure is altered by a number of factors. These include thrombin levels, treatment with common cardiovascular medications, such as aspirin, anticoagulants, statins and fibrates, as well as metabolic disease states such as diabetes mellitus and hyperhomocysteinaemia. In vitro studies of fibrin clot structure can provide information regarding fibre density, clot porosity, the mechanical strength of fibres and fibrinolysis. A change in fibrin clot structure, to a denser clot with smaller pores which is more resistant to lysis, is strongly associated with cardiovascular disease. This pathological change is present in patients with arterial as well as venous diseases, and is also found in a moderate form in relatives of patients with cardiovascular disease. Pharmacological therapies, aimed at both the treatment and prophylaxis of cardiovascular disease, appear to result in positive changes to the fibrin clot structure. As such, therapies aimed at 'normalising' fibrin clot structure may be of benefit in the prevention and treatment of cardiovascular disease.
