Abstract
Ethanol is toxic to the brain and causes various neurological disorders. Although ethanol can directly exert toxicity on neurons, it also acts on other cell types in the central nervous system. Blood vessel endothelial cells interact with, and are affected by blood ethanol. However, the effects of ethanol on the vascular structures of the brain have not been well documented. In this study, we examined the effects of binge levels of ethanol on brain vasculature. Immunostaining analysis indicated structural alterations of blood vessels in the cerebral cortex, which became more tortuous than those in the control mice after ethanol administration. The interaction between the blood vessels and astrocytes decreased, especially in the upper layers of the cerebral cortex. Messenger RNA expression analysis revealed a unique downregulation of Vegfa mRNA encoding vascular endothelial growth factor (VEGF)-A among VEGF, angiopoietin, endothelin family angiogenic and blood vessel remodeling factors. The expression of three proteoglycan core proteins, glypican-5, neurocan, and serglycin, was also altered after ethanol administration. Thus, binge levels of ethanol affect the expression of VEGF-A and blood vessel-supporting proteoglycans, resulting in changes in the vascular structure of the cerebral cortex.

Abstract
Objective This study was performed to investigate the serum vascular endothelial growth factor (VEGF) levels in Chinese patients with impaired glucose tolerance (IGT) and newly diagnosed type 2 diabetes mellitus (T2DM). Methods A total of 189 subjects (41 controls, 40 patients with IGT, and 108 patients with newly diagnosed T2DM) were recruited. Serum VEGF levels were determined by ELISA; other metabolic parameters were assessed by standard laboratory methods. Results There were significant differences in serum VEGF levels among the T2DM, IGT, and control groups (T2DM vs. controls: 72.00 [45.40, 98.35] pg/mL vs. 53.10 [36.30, 116.25] pg/mL; IGT vs. controls: 78.17 [55.52, 137.25] pg/mL vs. 53.10 [36.30, 116.25] pg/mL). Moreover, serum VEGF levels were positively associated with the homeostasis model assessment for insulin resistance (HOMA-IR) value. Multiple linear regression analysis indicated that the HOMA-IR value was an independent risk factor for elevated serum VEGF level. Conclusions Both IGT and T2DM patients exhibited increased serum VEGF levels, compared with controls; increased serum VEGF level was positively associated with the HOMA-IR value. Therefore, the increased serum VEGF level might partially result from increased insulin resistance in these patients.

Abstract
Accumulating evidence suggests that pathologic interactions between the heart and the kidney can contribute to the progressive dysfunction of both organs. Recently, there has been an increase in the prevalence of cardiovascular disease (CVD) and chronic kidney disease (CKD) due to increasing obesity rates. It has been reported that obesity causes various heart and renal disorders and appears to accelerate their progression. Vascular endothelial growth factor-A (VEGF-A) is a major regulator of angiogenesis and vessel permeability, and is associated with CVD and CKD. It is now recognized that alternative VEGF-A gene splicing generates VEGF-A isoforms that differ in their biological actions. Proximal splicing that includes an exon 8a sequence results in pro-angiogenic VEGF-A165a, whereas distal splicing inclusive of exon 8b yields the anti-angiogenic isoform of VEGF-A (VEGF-A165b). This review highlights several recent preclinical and clinical studies on the role of VEGF-A165b in CVD and CKD as a novel function of VEGF-A. This review also discusses potential therapeutic approaches of the use of VEGF-A in clinical settings as a potential circulating biomarker for CVD and CKD.

Abstract
Background Vascular endothelial growth factor-A (VEGF-A) promotes neovascularization and is attracting considerable attention as a remarkable risk factor in patients after acute myocardial infarction (AMI). In contrast, the association between VEGF-A165b, which is the main anti-angiogenic isoform of VEGF-A, and adverse clinical outcomes after AMI remains unclear. The present study aimed to investigate the association between serum VEGF-A165b and major adverse cardiac and cerebrovascular events (MACCEs) after percutaneous coronary intervention (PCI) for AMI. Methods We evaluated 23 patients with AMI who underwent primary percutaneous coronary intervention. VEGF-A and VEGF-A165b levels were measured on admission (day 1) and at days 3, 7, and 30 after PCI. Results The levels of total VEGF-A tended to be lower, while the ratio of VEGF-A165b to total VEGF-A tended to be higher in patients with MACCEs than in those without. The patients with a high ratio of VEGF-A165b to total VEGF-A had a significantly higher risk of MACCEs using the cut-off values for MACCEs at day 30 after PCI (0.87 vs. 0.25, log-rank test, p = 0.0058). Conclusion The assessment of VEGF-A165b combined with VEGF-A may be a valuable screening tool for predicting MACCEs in clinical practice.

Abstract
Hepatocellular carcinoma (HCC) has one of the highest death rates of any cancer in the world, and its incidence is increasing worldwide. Early-stage diagnosis of HCC is thus crucial for medical treatment. Detection of tumor biomarkers is one of the main methods for the early diagnosis of HCC. At present, α-fetoprotein (AFP) is the most practical serum biomarker for HCC diagnosis. However, the diagnostic accuracy of HCC with serum AFP exhibits both sensitivity and specificity far below satisfaction, especially with small sizes of HCC. As a result, the discovery of new biomarkers and/or their combination to enhance both the sensitivity and specificity for laboratory diagnosis of HCC is a crucial goal. With the development of new technology and advances in research, a number of new and specific biomarkers of HCC have been discovered. These biomarkers and their applications for the diagnosis, treatment monitoring and prognosis prediction of HCC, are reviewed in this article.

Abstract
The aim of the present study was to investigate the correlation between plasma the levels of vascular endothelial growth factor (VEGF) and major adverse cardiovascular events (MACE) in patients with acute myocardial infarction (AMI). A total of 124 patients with AMI undergoing emergency percutaneous coronary intervention (PCI) were selected, and plasma VEGF levels were measured 7 days after the onset of AMI using an enzyme-linked immunosorbent assay. The patients were divided into the L (≤190 pg/ml VEGF) and H (>190 pg/ml VEGF) groups, and were followed up every 2 months for an average of 12 months. MACE were recorded during follow-up. On the basis of these results, the patients were further divided into the MACE and non-MACE (N-MACE) groups, and the serum VEGF concentration was compared between the two groups. At the 6-month follow-up, the incidence of MACE in the H group was found to be significantly reduced compared with the L group. The serum VEGF concentration in the N-MACE group was significantly higher compared with the MACE group. Multinomial logistic regression revealed that reduced VEGF levels (β=1.243; 95% CI, 1.018-1.326; P=0.026) were independent risk factors for MACE. In conclusion, high plasma VEGF levels at 7 days after AMI onset facilitate the long-term prognosis in the same infarct zone in patients with AMI, while low plasma VEGF levels are independent risk factors for MACE.

Abstract
BACKGROUND Although vascular endothelial growth factor (VEGF) is elevated in patients with acute myocardial infarction (AMI), the clinical significance of its elevation remains unclear. The present study was designed to determine the relationship between VEGF and left ventricular dimension in patients with AMI. METHODS AND RESULTS Plasma VEGF levels were examined by enzyme-linked immunosorbent assay daily for one week and then weekly for four weeks in 38 patients with AMI (65.4 ± 1.7 years). Left ventriculography was performed at 14 days, 6 months, and 2 years after the onset of AMI. Plasma VEGF levels were significantly elevated and reached a peak on day 6. Peak plasma VEGF levels positively correlated with both end-diastolic and end-systolic volume indices at 14 days after the onset of AMI. When patients with AMI were divided into two groups according to plasma VEGF levels on admission, left ventricular volume indices were higher in the high VEGF group than in the low VEGF group at the subacute phase of AMI (14 days). These differences were no longer present in the chronic phase of AMI. CONCLUSION Plasma VEGF levels were increased in patients with AMI, and peak levels were associated with left ventricular volume indices in the subacute phase, suggesting an important role of endogenous VEGF in the left ventricular dimension in patients with AMI.

Abstract
Hepatocellular carcinoma (HCC) is the commonest primary malignant cancer of the liver in the world. This study was conducted to investigate the serum levels of hepatocyte growth factor (HGF)in HCC patients and the relationship with tumor progression and known prognostic parameters. Fifty-four patients with HCC were investigated. Pretreatment HGF levels were employed the quantitative sandwich enzyme immunoassay technique (ELISA). Age and sex matched 20 healthy controls were included in the analysis. The median age of the patients was 60 years (range 36-77 years); where males consistituted of majority of the group (88.8%). All of patients had cirrhotic history. Fourty-six percent (n = 25) of patients had Child-Pugh Score A, 30% (n = 16) had Score B or C. All of the patients were treated with local therapies but none of them received sorafenib. The baseline serum HGF levels were significantly higher in patients with HCC than in the control group (p < 0.001). Male patients had higher serum HGF levels compared with female patients (p = 0.01). Serum HGF levels were significantly higher in the patients with elevated serum ALT levels than others with normal serum ALT levels (p = 0.05). Poor performance status (p < 0.001), viral etiology of cirrhosis (p = 0.03), larger tumor size (p = 0.01), lower serum hemogloblin levels (p = 0.03), and not be treated for HCC (p = 0.001) related to worse survival. However, serum HGF did not have significantly adverse effect on survival (p = 0.58). Despite serum HGF levels were found diagnostic value, serum HGF levels had no prognostic value in patients with HCC.

Abstract
AIM: To evaluate the plasma level of circulating heptocyte growth factor (HGF) in patients with comorbidity of post-infarction chronic heart failure (CHF), type 2 diabetes mellitus (T2DM) and obesity. We also aimed to assess possible correlations between HGF levels and parameters of carbohydrate and lipid metabolism, as well as myocardial functional characteristics and classic biochemical severity markers for CHF.17Сахар ный диабет КардиологияСахарный диабет. 2013;(2):17-25
MATERIALS AND METHODS: We enrolled 100 patients for participation in this study, including the following subgroups: 20 individuals with- out cardiovascular and glycemic disorders, 30 patients with CHF, 25 patients with CHF/T2DM comorbidity and 25 diabetic patients with no signs of heart failure. Quantitative plasma HGF analysis was performed with enzyme-linked immunosorbent assay (ELISA).
RESULTS: Plasma HGF was elevated both in patients with CHF and T2DM as measured against healthy control group. The elevation was most prominent in patients with CHF/T2DM comorbidity and was found to correlate with HbA1c level (r=0.52, p=0.03). Plasma HGF also correlated with BMI (r=0.42, p=0007) in a unified study group, though we observed no statistically significant difference between subgroups with a trend toward higher HGF in obese patients with CHF/T2DM comorbidity (626.1?254.1 pg/ml vs 742.0?210.7 pg/ml respectively; p 0.05). Interestingly, plasma HGF was also significantly higher in controls with BMI 30 km/m2 (324.1?107.7 pg/ml vs 436.9?112.3 pg/ml, p=0.03).Circulating HGF correlated with plasma levels of N-terminal fragment of B-type natriuretic peptide (NT-proBNP) and such structural and functional myocardial characteristics as left atrial size and maximum volume along with left ventricular ejection fraction (EF), end-diastolic volume (EDV) and end-diastolic dimension (EDD).
CONCLUSION: These findings suggest that HGF may potentially serve as a prediction marker for unfavorable myocardial remodeling and poor prognosis in CHF patients with T2DM and obesity, though this possibility should be further investigated in follow-up studies.

Abstract
Left ventricular (LV) remodeling after myocardial infarction (MI) indicates a high risk of heart failure and death, but LV remodeling remains difficult to predict. Biomarkers may help to refine risk stratification for a more personalized medical approach. They may also shed light on the pathophysiologic processes involved. We performed a systematic review of the published evidence about the association of circulating biomarkers with LV remodeling after MI. We selected 59 publications. Overall, these studies examined 112 relations between 52 different biomarkers and LV remodeling. The biomarkers most consistently associated with LV remodeling were involved in extracellular matrix turnover or neurohormonal activation: matrix metalloproteinase-9, collagen peptides, and B-type natriuretic peptide. This review underscores the vitality of the research on LV remodeling but concludes that the ideal biomarker has not yet been identified. To reach this goal, future studies will have to be larger, have standardized imaging end points, and include replication populations to define optimal cutoffs for LV remodeling prediction. Cardiovascular magnetic resonance appears to be the best technique for LV remodeling assessment but its current availability may be a concern for recruitment for multicenter studies. Recent technologic advances will probably yield new candidate biomarkers of LV remodeling. Tests are necessary to determine whether a multimarker approach would significantly improve risk prediction.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) is induced by myocardial ischemia and is thought to facilitate cardiovascular repair after acute myocardial infarction (AMI). However, the association between the plasma VEGF levels and clinical outcome in AMI patients is unclear. METHODS AND RESULTS We evaluated 879 AMI patients undergoing successful primary revascularization within 24h of symptom onset. The patients were classified into 3 groups according to tertiles of plasma VEGF levels at 7 days after the onset of AMI. Major adverse cardiovascular and cerebrovascular events (MACCE), defined as cardiac death, recurrent acute coronary syndrome, hospital readmission for heart failure, or stroke, were assessed during the 6-month follow-up period. The incidence of MACCE was the least frequent in the middle tertile. Compared to the middle tertile, patients in the low tertile were at a significantly higher risk for MACCE even after adjusting for baseline characteristics (hazard ratio [HR] 2.67, 95% confidence interval [CI] 1.18-6.06, P=0.019). An absence of statin treatment before onset and a younger age (HR 0.54, 0.87; 95%CI 0.33-0.90, 0.76-0.99; P=0.017, 0.037; respectively) were significantly associated with low VEGF. CONCLUSIONS Low plasma VEGF levels at 7 days after the onset of AMI were associated with a significantly increased risk for MACCE during 6 months of follow-up.

Abstract
UNLABELLED Aim As experimental studies suggest that hepatocyte growth factor (HGF) is cardioprotective after myocardial infarction (MI), this study sought to investigate relationships between circulating levels of HGF and left ventricular (LV) remodelling in patients after acute MI. METHODS AND RESULTS This prospective multicentre study included 246 patients with a first anterior Q-wave MI. Serial echocardiographic studies were performed at hospital discharge and 3 and 12 months after MI; quantitative analysis was performed at a core echocardiography laboratory. Blood samples to measure HGF, brain natriuretic peptide (BNP), and C-reactive protein were obtained at discharge and at the 1, 3, and 12 month follow-up visits. Plasma HGF levels were high at baseline, decreased at 1 month, and remained stable thereafter. In the post-MI period (at 3 and 12 months), HGF levels were positively associated with LV volumes, wall motion systolic index, E/Ea, and BNP; and negatively with LV ejection fraction. High HGF levels were associated with higher C-reactive protein levels. Multivariate analysis showed that both BNP (P < 0.0001) and C-reactive protein (P < 0.0001) were independently associated with HGF levels at 3 and 12 months. Patients who died or were rehospitalized for heart failure during follow-up had higher HGF levels at 1 month (P = 0.0006), 3 months (P = 0.018), and 1 year (P = 0.006) after MI. CONCLUSIONS Circulating HGF levels correlate with all markers of LV remodelling after MI and are associated with rehospitalization for heart failure.

Abstract
Ischemia-reperfusion and chronic injuries associated with small-for-size liver transplantation (SFSLT) impair the regeneration of liver graft and induce liver fibrosis. Mesenchymal stem cells (MSCs) can prevent the development of liver fibrosis, and hepatocyte growth factor (HGF) can also attenuate liver cirrhosis. Our previous studies have demonstrated that higher occurrence of liver fibrosis existed in rats post-SFSLT, and that implantation of HGF/MSCs, the human HGF (hHGF)-expressing MSCs, can improve liver regeneration, reduce mortality of rats, as well as have the potent antifibrotic effect in this SFSLT model. In the present study, we implanted HGF/MSCs into liver grafts via the portal vein and investigated their role in antifibrosis effect, using a 30% SFSLT rat model. Fibrosis indexes, including laminin (LN), hyaluronic acid (HA) levels in serum and hydroxyproline (Hyp) content in the liver grafts, the expression of transforming growth factor-beta1 (TGF-beta(1)), rat HGF (rHGF), alpha-smooth muscle actin (alpha-SMA) in hepatic stellate cells (HSCs), alanine aminotransferase (ALT), total bilirubin (BIL), and albumin (ALB) levels in serum, in rats in different treatment groups were assessed at different time points. We found that HGF/MSCs significantly inhibited the formation of liver fibrosis in rats undergoing SFSLT, while MSCs and HGF had synergistic effects in the process. The antifibrosis effect of HGF/MSCs may have contributed in modulating the activation and apoptosis of HSCs, elevating the rHGF expression level, and decreasing the TGF-beta(1) secretion of activated HSCs. These studies suggest that HGF/MSCs may be a novel therapeutic option for the treatment of liver fibrosis after SFSLT.

Abstract
Hepatocyte growth factor (HGF), which was originally isolated as a liver generating factor, enhances hematopoiesis. To study the effect of HGF on hematopoietic stem cells (HSCs) and hematopoietic progenitor cells (HPCs), we generated severe combined immunodeficiency (SCID) mice producing human (h) HGF and/or stem cell factor (SCF) by transferring the relevant genes to fertilized eggs, and then transplanted hematopoietic progenitors from human cord blood into the transgenic (Tg) SCID mice. Six months after transplantation, a significantly larger number of human cells were found in the Tg SCID mice than in non-Tg controls. Characteristically, the recipient SCID mice producing h HGF (HGF-SCID) had a significantly increased number of h CD41+ cells, whereas the SCF-SCID recipients had more CD11b+ cells. Significantly large numbers of CD34+ progenitors were found in the SCID mice transferred with both h HGF and h SCF genes (HGF/SCF-SCID) when compared with HGF-SCID or SCF-SCID mice. These results imply that HGF supports the differentiation of progenitors in megakaryocyte lineage, whereas SCF supports that in myeloid lineage. The results also imply that HGF acts on HSCs/HPCs as a synergistic proliferative factor combined with SCF. We have demonstrated the advantage of the human cytokine-producing animal in the maintenance of human HSCs.

Abstract
BACKGROUND The rising incidence of hepatocellular cancer in the US and worldwide has sparked a renewed interest in HCC serum markers. HCC typically develops in patients with chronic liver disease and cirrhosis. It is in these target populations that serum markers are most urgently needed. Unfortunately, the currently available markers lack sensitivity and specificity. A number of novel candidate markers have recently been introduced. METHODS We performed a review of the literature (2001-2006) of traditional and novel serum markers for hepatocellular cancer. RESULTS Several promising new HCC markers have been identified over the past 5 years. They include single proteins, complex proteomics features, and tumor-specific autoantibodies. The excitement about the new markers is tempered by the realization that none of them have yet met the most stringent criteria defined by the Early Detection Research Network (EDRN). CONCLUSION A new generation of HCC serum markers awaits validation in properly controlled clinical studies.

Abstract
BACKGROUND Previous studies have shown that angiopoietic growth factors, including vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2), hepatocyte growth factor (HGF) and transforming growth factor (TGF)-beta1 are released after acute myocardial infarction (AMI). It was suggested that the release of these factors, triggered by ischemia, may be related to a reparative neoangiogenetic process. METHODS Plasma VEGF, Ang-2, HGF and TGF-beta levels were measured on admission (baseline) and at various times during the acute (0-48 h) and the subacute (48-240 h) phase in 44 patients with AMI. RESULTS In the present study, we have explored in detail the kinetics of release of these growth factors after AMI with the precise aim of evaluating the existence of a double wave of release of these factors: (i) a first wave in the acute and (ii) a second one in the subacute period. The results of these analyses provided evidence for an early (peak at 24-28 h) and late (peak at approximately 170 h) increase of VEGF, Ang-2 and TGF-beta. CONCLUSIONS According to these data, we suggest that two waves of release of angiogenic factors occur after AMI. The early release makes part of an acute phase response, whereas the late release may underlie the induction of angiogenetic mechanisms involved in tissue reparation.

Abstract
Human mesenchymal stem cells (hMSC) are adult stem cells with multipotent capacities. The ability of mesenchymal stem cells to differentiate into many cell types, as well as their high ex vivo expansion potential, makes these cells an attractive therapeutic tool for cell transplantation and tissue engineering. hMSC are thought to contribute to tissue regeneration, but the signals governing their mobilization, diapedesis into the bloodstream, and migration into the target tissue are largely unknown. Here we report that hepatocyte growth factor (HGF) and the cognate receptor HGFR/c-met are expressed in hMSC, on both the RNA and the protein levels. The expression of HGF was downregulated by transforming growth factor beta. HGF stimulated chemotactic migration but not proliferation of hMSC. Therefore the HGF/c-met signaling system may have an important role in hMSC recruitment sites of tissue regeneration. The controlled regulation of HGF/c-met expression may be beneficial in tissue engineering and cell therapy employing hMSC.

Abstract
BACKGROUND Hepatocyte growth factor (HGF) has been reported as a marker of atherosclerosis and of thrombi synthesis, but the relationship between HGF and proven coronary thrombi has not been described. The aim of this study was to investigate this relationship in patients with chest pain. METHODS AND RESULTS The study group comprised 107 patients with chest pain (61 acute myocardial infarction (AMI), 18 unstable angina, 15 stable angina, and 13 others; 65 males, 42 females; 66+/-11 years old). The presence of thrombi was evaluated by angiography, intravascular ultrasonography, angioscopy, and computed tomography. Serum HGF concentrations were measured using a new enzyme-linked immunosorbent assay. Serum HGF was significantly higher in the patients with AMI (335.0 +/-197.5 pg/ml), unstable angina (269.1+/-152.7 pg/ml), acute aortic dissection (320.3+/-116.5 pg/ml), and pulmonary thromboembolism (292.5+/-101.9 pg/ml), than in those with stable angina (171.2+/-56.1 pg/ml). Serum HGF concentration was also higher in those patients with proven thrombi than in those patients without (326.7+/-189.7 pg/ml vs 226.9+/-110.8 pg/ml). CONCLUSION Increased serum HGF concentrations correlate with the presence of thrombi in patients with acute coronary syndrome, acute aortic dissection, and pulmonary thromboembolism.

Abstract
BACKGROUND Hepatocyte growth factor (HGF) is a member of growth factor with a variety of known activities, including angiogenesis promotion and antiapoptotic action. It prevents acute graft-versus-host disease after bone marrow transplantation and prolongs allogenic graft survival in rats. The aim of the study was to investigate the relationship between serum HGF concentration and the grade of acute cellular rejection of heart transplant. METHODS We studied 68 male heart recipients. All of them received triple-drug immunosuppression: cyclosporine A, prednisone, and azathioprine or mycofenolate mofetil. All patients were without signs of heart failure. Blood samples were taken before elective ambulatory endomyocardial biopsy. Biopsy specimens were graded with the International Society for Heart and Lung Transplantation scale. Acute cellular rejection grade 3A and higher were considered as significant. Measurement of serum HGF was made by enzyme-linked immunosorbent assay. RESULTS We found a positive relationship between serum HGF levels and grade of cellular rejection. As an indicator for the detection of cell rejection processes, HGF with cutoff 2000 pg/ml seems to be useful. CONCLUSIONS The results of this study demonstrate that HGF can be useful as an indicator for heart graft cell rejection.

Abstract
BACKGROUND Patients with cyanotic congenital heart disease (C-CHD) usually have myocardial thickening and fibrosis, both of which can affect the course of surgical management. Hypoxia and ischemia may stimulate microvessel formation in the myocardium, which may accelerate the myocardial thickening and fibrosis. Whether hyperplasia of microvessels occurs in the myocardium of C-CHD was investigated in this report. METHODS AND RESULTS The patients were divided into 2 groups; the C-CHD group (n = 22), and the acyanotic congenital heart disease (A-CHD) group (n = 24). The microvessels and vascular endothelial growth factor (VEGF) mRNA of the myocardium were detected by immunohistochemical staining assay and real-time quantitative reverse transcriptase polymeric chain reaction, respectively. The serum VEGF levels were measured by using enzyme-linked immunosorbent assay. The results were that: (1) the number of microvessels in the myocardium were more in the C-CHD group than in A-CHD group; (2) the serum VEGF levels in the C-CHD group vs the A-CHD group were higher in the preoperative period (p < 0.001), but there was no difference after operation; and (3) VEGF protein and the expression of VEGF mRNA in the myocardium were higher in the C-CHD group than in the A-CHD group (p < 0.01). CONCLUSIONS Myocardial microvessels formed in the myocardium of patients with C-CHD, possibly mediated by increasing VEGF levels (for this group of patients).
