Abstract
BACKGROUND AND OBJECTIVE Thrombin-antithrombin complex (TAT) is a prethrombotic marker, and its application in ischemic stroke is still uncertain. The purpose of this systematic review and meta-analysis is to evaluate the relationship between plasma TAT and ischemic stroke base on the current evidence. METHODS A systematic literature search was conducted for searching the relative studies that investigated the association of TAT and ischemic stroke in PubMed, EMBASE, and Cochrane library databases. Mean difference and 95% confidence interval as the effect sizes were synthesized by random effects model in Review Manager (RevMan) Version 5.4. The heterogeneity was investigated using the chi-square test and the possible sources of heterogeneity were explored by sensitivity analysis and meta-regression. The publication bias was estimated by Egger's tests. RESULTS A total of 12 eligible studies were included involving 1431 stroke cases and 532 healthy controls, of which six studies were eventually included in the meta-analysis. Plasma TAT in patients with ischemic stroke was significantly higher than that in healthy controls (MD 5.31, 95% CI = 4.12-6.51, P < 0.0001, I2 = 97.8%). There is a difference of TAT level in the same period among cardioembolic, lacunar, and atherothrombotic stroke (all P < 0.0001), in which the cardioembolic stroke with the highest level. Meanwhile, it is significant of TAT levels among various phases of cardioembolic stroke and the acute phase are markedly elevated (MD 7.75, 95CI%, 6.07-9.43, P < 0.001). However, no difference was found in the atherothrombotic (P = 0.13) and lacunar stroke (P = 0.34). Besides, the higher TAT level is closely related to the poor prognosis of patients with ischemic stroke, including higher recurrence, mortality, unfavorable recovery (modified Rankin scale > 2), and poor revascularization. CONCLUSIONS This study suggested that plasma TAT levels are different in ischemic stroke subtypes, which are closely associated with the progression and might have an effect on the prognosis.

Abstract
: To evaluate analytic and clinical performance of plasma thrombin-antithrombin complex (TAT) and D-dimer assay in assessing the severity and outcome of acute ischemic stroke. The prospective study was conducted and extended from January 2018 to December 2018. A total of 236 patients admitted within 24 h after neurologic symptoms onset were recruited. The median TAT and D-dimer levels were significantly higher in the acute ischemic stroke patients than in the controls. The average TAT levels in patients with mild, moderately severe and severe stroke were 1.75 [interquartile ranges (IQR), 1.1-2.6], 3.3 (IQR, 1.8-4.5) and 13.5 (IQR, 7.2-15.3) ng/ml. The D-dimer levels of respective patient groups were 0.39 (IQR, 0.22-0.73), 0.58 (IQR, 0.39-1.25) and 3.59 (IQR, 1.73-4.74) mg/l. With the optimal cut-off TAT level (1.75 ng/ml) determined from receiver operating characteristic analysis, the Area under the curve (AUC), the sensitivity and specificity of TAT for stroke diagnosis were 0.763, 58.1 and 87.8%. The cut-off D-dimer level was 0.38 mg/l and the AUC, the sensitivity and specificity were 0.772, 60.2 and 88.9%. The Area under the receiver operating characteristic curves (AUROCs) and sensitivity in the moderate to severe stroke increased to 0.903 and 86.9% for TAT, and 0.880 and 80.3% for D-dimer, respectively. Age and high TAT level were significant independent risk factors for stroke severity. Age, high initial National Institutes of Health Stroke Scale score and high TAT level were significant independent poor prognostic factors on multivariate analysis. TAT and D-dimer were superior in separating the moderate-to-severe stroke than mild stroke. A high TAT plasma level is an independent predictor for stroke severity and poor prognosis during 1-month follow-up.

Abstract
The endothelium has a crucial role in proper hemodynamics. Inflammatory bowel disease (IBD) is mainly a chronic inflammatory condition of the gastrointestinal tract. However, considerable evidence points to high cardiovascular risk in patients with IBD. This review positions the basic mechanisms of endothelial dysfunction in the IBD setting (both clinical and experimental). Furthermore, we review the main effects of drugs used to treat IBD in endothelial (dys)function. Moreover, we leave challenging points for enlarging the therapeutic arsenal for IBD with new or repurposed drugs that target endothelial dysfunction besides inflammation.

Abstract
Stroke is the fifth leading cause of death and the most frequent cause of disability worldwide. Currently, stroke diagnosis is based on neuroimaging; therefore, the lack of a rapid tool to diagnose stroke is still a major concern. In addition, therapeutic approaches to combat ischemic stroke are still scarce, since the only approved therapies are directed toward restoring blood flow to the affected brain area. However, due to the reduced time window during which these therapies are effective, few patients benefit from them; therefore, alternative treatments are urgently needed to reduce stroke brain damage in order to improve patients' outcome. The inflammatory response triggered after the ischemic event plays an important role in the progression of stroke; consequently, the study of inflammatory molecules in the acute phase of stroke has attracted increasing interest in recent decades. Here, we provide an overview of the inflammatory processes occurring during ischemic stroke, as well as the potential for these inflammatory molecules to become stroke biomarkers and the possibility that these candidates will become interesting neuroprotective therapeutic targets to be blocked or stimulated in order to modulate inflammation after stroke.

Abstract
Ischemia-reperfusion injury (IRI) is a severe problem patients diagnosed with acute limb ischemia. Recently, microRNAs (miR) have emerged as regulators of IRI as well as ischemic preconditioning and ischemic postconditioning. Therefore, using rat models, this study aims to explore all of the possible mechanisms that miR-19 exhibits with its relation to the transforming growth factor beta (TGF-β1)/Smad signaling pathway in the lower limb IRI. An immunofluorescence staining method was used to identify the Krueppel-like factor 10 (KLF10) positive expression and the location of KLF10 expression. The targeting relationship that miR-19 has with KLF10 was verified by the dual-luciferase reporter gene assay. Vascular endothelial cells (VECs) were treated with elevated or suppressed miR-19 or KLF10 knockdown. A 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide assay was used to test cell proliferation, and flow cytometry was employed to detect both cell cycle and apoptosis. The KLF10-positive expression in the VECs (both in cytoplasm and nucleus) was found to be elevated in the IRI rats. We found that miR-19 was downregulated, KLF10 upregulated, and the TGF-β1/Smad signaling pathway activated in the vascular epithelial tissues of IRI rats. KLF10 is a target gene of miR-19. Overexpression of miR-19 decreased the expression of KLF10, TGF-β1, and Smad2/3. Decreased miR-19 inhibited VEC proliferation, arrested VECs at the G1 phase, and promoted the apoptosis of VECs following their lower limb I/R injury. These results indicate miR-19 as being an inhibitor in the VEC injury of IRI via the TGF-β1/Smad signaling pathway by suppression of KLF10.

Abstract
Background Although the role of microparticles was recently implicated in stroke pathophysiology, the association between microparticles and inflammation is still not fully understood. The aim of this cohort study of 66 patients was to assess a relation between haemostatic factors, C-reactive protein and clinical outcome of ischaemic stroke. Methods Plasma microparticles procoagulant activity, concentrations of tissue factor-bearing microparticles, tissue factor and tissue factor pathway inhibitor in ischaemic stroke patients were determined with enzyme-linked immunosorbent assays at the time of initial diagnosis, along with serum C-reactive protein concentrations. Patients were divided into two groups depending on their C-reactive protein concentrations (C-reactive protein <3 mg/L; n = 28 vs. C-reactive protein ≥3 mg/L; n = 38). The analysed clinical outcome measures included the National Institutes of Health Stroke Scale and the Barthel Index. Results The two C-reactive protein groups did not differ significantly in terms of microparticles procoagulant activities, tissue factor-bearing microparticles, tissue factor and tissue factor pathway inhibitor concentrations. A significant correlation was observed between tissue factor pathway inhibitor and National Institutes of Health Stroke Scale score at admission ( R = 0.3, P = 0.03). Patients with C-reactive protein ≥3 mg/L presented with significantly higher National Institutes of Health Stroke Scale scores (median, 9.00 vs. 5.50, P = 0.002) and lower Barthel Index scores (median, 20.00 vs. 65.00, P = 0.002) than individuals with C-reactive protein <3 mg/L. The C-reactive protein concentrations correlated positively with National Institutes of Health Stroke Scale scores ( R = 0.3, P = 0.02) and inversely with Barthel Index scores ( R = - 0.4, P = 0.002). Conclusions Altogether, these findings imply that haemostatic parameters (microparticles, tissue factor-bearing microparticles, tissue factor, tissue factor pathway inhibitor) do not account for elevated C-reactive protein concentrations in ischaemic stroke patients.

Abstract
The major physiological inhibitor of plasminogen activator, type I plasminogen activator inhibitor (PAI-1), controls blood clotting and tissue remodeling events that involve cell migration. Transforming growth factor type β (TGFβ) and epidermal growth factor (EGF) interact synergistically to increase PAI-1 mRNA and protein levels in human HepG2 and mink Mv1Lu cells. Other growth factors that activate tyrosine kinase receptors can substitute for EGF. EGF and TGFβ regulate PAI-1 by synergistically activating transcription, which is further amplified by a decrease in the rate of mRNA degradation, the latter being regulated only by EGF. The combined effect of transcriptional activation and mRNA stabilization results in a rapid 2-order of magnitude increase in the level of PAI-1. TGFβ also increases the sensitivity of the cells to EGF, thereby recruiting the cooperation of EGF at lower than normally effective concentrations. The contribution of EGF to the regulation of PAI-1 involves the MAPK pathway, and the synergistic interface with the TGFβ pathway is downstream of MEK1/2 and involves phosphorylation of neither ERK1/2 nor Smad2/3. Synergism requires the presence of both Smad and AP-1 recognition sites in the promoter. This work demonstrates the existence of a multidimensional cellular mechanism by which EGF and TGFβ are able to promote large and rapid changes in PAI-1 expression.
