Abstract
PURPOSE Vascular dysfunction has been demonstrated in patients with Alzheimer's disease (AD). Exercise is known to positively affect vascular function. Thus, the aim of our study was to investigate exercise-induced effects on vascular function in AD. METHODS Thirty-nine patients with AD (79 ± 8 years) were recruited and randomly assigned to exercise training (EX, n = 20) or control group (CTRL, n = 19). All subjects performed 72 treatment sessions (90 min, 3 t/w). EX included moderate-high-intensity aerobic and strength training. CTRL included cognitive stimuli (visual, verbal, auditive). Before and after the 6-month treatment, the vascular function was measured by passive-leg movement test (PLM, calculating the variation in blood flow: ∆peak; and area under the curve: AUC) tests, and flow-mediated dilation (FMD, %). A blood sample was analyzed for vascular endothelial growth factor (VEGF). Arterial blood flow (BF) and shear rate (SR) were measured during EX and CTRL during a typical treatment session. RESULTS EX group has increased FMD% (+ 3.725%, p < 0.001), PLM ∆peak (+ 99.056 ml/min, p = 0.004), AUC (+ 37.359AU, p = 0.037) and VEGF (+ 8.825 pg/ml, p = 0.004). In the CTRL group, no difference between pre- and post-treatment was found for any variable. Increase in BF and SR was demonstrated during EX (BF + 123%, p < 0.05; SR + 134%, p < 0.05), but not during CTRL treatment. CONCLUSION Exercise training improves peripheral vascular function in AD. These ameliorations may be due to the repetitive increase in SR during exercise which triggers NO and VEGF upregulation. This approach might be included in standard AD clinical practice as an effective strategy to treat vascular dysfunction in this population.

Abstract
OBJECTIVES Despite the initial clinical benefit, resistance to antiangiogenic therapies develops through the activation of alternative pathways. We measured plasma levels of circulating angiogenic factors to explore their predictive role in metastatic renal cell carcinoma (mRCC) patients treated with pazopanib. MATERIALS AND METHODS mRCC patients receiving first-line pazopanib were prospectively enrolled. The levels of circulating interleuchine (IL)-6, IL-8, stromal derived factor-1, vascular endothelial growth factor-A, hepatocyte growth factor (HGF), osteopontin, and E-selectin were quantified at baseline and every 4 weeks until disease progression (PD). Patients were dichotomized into "low" and "high" subgroups by a cutoff point defined by the respective median circulating angiogenic factor (CAF) value at baseline. Then, association with the objective response was determined. Changes in CAF levels between baseline and PD were also compared. RESULTS Among 25 patients included in the final data set, 6 patients were still on treatment. As best response, 12 patients presented a partial response (48%), 9 showed stable disease, and 4 showed PD. The median follow-up was 31.9 months. The median progression-free survival was 14.8 months. Low baseline levels of IL-6, IL-8, HGF, and osteopontin were found to be significantly associated with objective response. In addition, patients with low baseline levels of HGF showed longer progression-free survival and overall survival, whereas patients with low baseline levels of IL-8 showed longer overall survival. Among patients experiencing PD, the median plasma levels of stromal derived factor-1 and vascular endothelial growth factor-A were significantly higher compared with the baseline (P=0.01; P=0.011). Conversely, the median levels of E-selectin were significantly lower compared with the baseline (P=0.017). CONCLUSION Changes in levels of selected CAFs were associated with response/resistance to pazopanib in mRCC patients.

Abstract
PURPOSE To investigate the changes in tumor markers (TMs), coagulation function and vascular endothelial growth factor (VEGF) in patients with ovarian cancer (OC) and benign ovarian disease (BOD). METHODS A total of 68 OC patients admitted to and treated in our hospital were selected (OC group), and another 68 BOD patients in the same time period were enrolled (BOD group). The variations in TMs, coagulation function and VEGF in OC and BOD patients were explored by analyzing the TMs, coagulation function and expression levels of serum VEGF and D-dimer in OC group and BOD group as well as the differences in TMs and coagulation function in patients in different stages. RESULTS The values of TMs such as cancer antigen 125 (CA125), carbohydrate antigen 19.9 (CA19.9) and human epididymis protein 4 (HE4) in OC group were remarkably higher than those in BOD group, with significant differences (p<0.05). The values of those TMs were relatively low in the patients in stage I-II but relatively high in the patients in stage III-IV, and the patients in stage I-II had evidently lower values of those TMs than those in stage III-IV (p<0.05). The coagulation function was similar in both groups (p>0.05), while OC group exhibited a notably higher serum fibrinogen (FIB) level than BOD group (p<0.05). The levels of coagulation function indexes [prothrombin time (PT), thrombin time (TT) and activated partial thromboplastin time (APTT)] in the patients in stage I-II were comparable to those in stage III-IV, showing no differences (p>0.05), but the serum FIB level was markedly higher in the patients in stage III-IV than that in in stage I-II (p<0.05). The expression level of serum VEGF was increased distinctly in OC group compared with that in BOD group [(378.15±94.45) pg/mL vs. (164.02±67.38) pg/mL, p<0.05]. Moreover, OC group manifested obviously elevated expression level of serum D-dimer in comparison with BOD group [(4.58±1.48) μg/mL vs. (0.67±0.12) μg/mL, p<0.05]. CONCLUSIONS TMs, coagulation function indexes and serum VEGF and D-dimer are highly expressed in OC patients, and the combined detection of TMs, coagulation function and serum VEGF can serve as an important method of diagnosing OC.

Abstract
BACKGROUND The aim of this study was to analyze the clinical application of cortex phellodendri compound fluid (CPCF) in the treatment of diabetic foot ulcers. MATERIAL AND METHODS From January 2012 to December 2015, a total of 720 cases of diabetic foot ulcers (DFU) were randomly assigned into an experimental group (n=540) that was treated by CPCF and a control group (n=180) that was treated by a Kangfuxin solution (KFS). After 4 weeks of treatment, their ulcer area, serum growth factor, clinical total effective rate, and incidence of adverse events were assessed. RESULTS There were 720 patients who completed the trial. The experimental group was superior to the control group in reducing ulcer area, increasing growth factor content, and total effective rate (P<0.05). There was no significant difference in the adverse events rates between the 2 groups. CONCLUSIONS CPCF external treatment of diabetic foot ulcer can promote ulcer healing and increase the concentration of growth factors, and it is safe and reliable.

Abstract
BACKGROUND In recent years, more and more attention has been paid to the role of skin microcirculation in the pathogenesis of psoriasis. The vascular network of the skin is mainly distributed in the dermis and the subcutaneous fat layer join. The microvessels are composed of terminal arterioles, arteriovenous capillaries, and postcapillary venules. Vascular endothelial growth factor (VEGF) plays an important role in the pathogenesis of psoriasis by promoting angiogenesis. The purpose of this study is to evaluate the relationship between serum VEGF and psoriasis vulgaris. METHODS Embase, CENTRAL, PubMed, China Biology Medicine Database, China National Knowledge Database, Wan Fang Database, and Chong Qing VIP Database will be searched to collect case-control studies and cohort studies and evaluate the relationship between serum VEGF and psoriasis vulgaris. The search time limits will be from the establishment of the database to December 2020. Two researchers will independently screen the studies, extract data, and evaluate the risk of bias of the studies. The Meta-analysis will be carried out with the RevMan5.3 software. The quality of all included studies will be evaluated by the Newcastle-Ottawa scale. RESULTS This study will evaluate the relationship between serum VEGF and the pathogenesis of psoriasis vulgaris. CONCLUSION This study will provide a theoretical basis for the pathogenesis of psoriasis vulgaris. OSF REGISTRATION NUMBER DOI 10.17605/OSF.IO/6DV8P.

Abstract
In our work, we aim to identify new candidate host biomarkers to discriminate between active TB patients (n = 28), latent infection (LTBI; n = 27) and uninfected (NoTBI; n = 42) individuals. For that, active TB patients and their contacts were recruited that donated serum and saliva samples. A multiplex assay was performed to study the concentration of different cytokines, chemokines and growth factors. Proteins with significant differences between groups were selected and logistic regression and the area under the ROC curve (AUC) was used to assess the diagnostic accuracy. The best marker combinations that discriminate active TB from NoTBI contacts were [IP-10 + IL-7] in serum and [Fractalkine + IP-10 + IL-1α + VEGF] in saliva. Best discrimination between active TB and LTBI was achieved using [IP-10 + BCA-1] in serum (AUC = 0.83) and IP-10 in saliva (p = 0.0007; AUC = 0.78). The levels of TNFα (p = 0.003; AUC = 0.73) in serum and the combination of [Fractalkine+IL-12p40] (AUC = 0.83) in saliva, were able to differentiate between NoTBI and LTBI contacts. In conclusion, different individual and combined protein markers could help to discriminate between active TB and both uninfected and latently-infected contacts. The most promising ones include [IP-10 + IL-7], [IP-10 + BCA-1] and TNFα in serum and [Fractalkine + IP-10 + IL-1α + VEGF], IP-10 and [Fractalkine+IL-12p40] in saliva.

Abstract
BACKGROUND Subclinical synovitis occur long before clinical haemophilic arthropathy (HA). New biomarkers are needed for early detection of HA. AIM To compare the levels of tissue inhibitors of metalloproteinase-1 (TIMP-1) and vascular endothelial growth factor (VEGF)in severe haemophilia A boys on prophylaxis and on-demand therapy to healthy boys and correlate them with the haemophilia joint health score (HJHS) & the Denver magnetic resonance imaging (MRI) scale; hence, determine their values in early detection of HA. METHODS Haemophilia joint health score, serum TIMP-1, VEGF and Denver MRI score were assessed in 50 boys with severe haemophilia A (31 on prophylactic factor VIII therapy (62%) with a dose of 15 IU/kg/twice weekly) and 50 age-matched healthy boys. RESULTS Boys with severe haemophilia A had significantly higher TIMP-1 240 ng/mL, SD200-350 (P < .001) and VEGF 600 pg/mL, SD400-1100 (P < .001). Their mean HJHS was 4.5 ± 3.0 (0-11) and their mean Denver MRI score was 5.55 ± 1.6 (2.00-8.00). A significant positive correlation was found between TIMP-1 and VEGF (P < .001), BMI Z-score (P = .029), HJHS (P = .041)and total MRI score (<.001). Significant correlations were found between VEGF and age (P < .001), HJHS (P = .003) and total MRI score (P < .001). Boys with severe haemophilia A on prophylaxis therapy had significantly lower HJHS (P = .021), VEGF (P < .001), TIMP-1 (P = .002) and total MRI score (P = .021) than those on on-demand therapy. Receiver operating characteristic curve, defined a cut-off value of 160 ng/mL for TIMP-1 with a sensitivity of 90% and specificity of 60% and that of 350 pg/mL for VEGF with a sensitivity of 78% and specificity of 88% for discrimination between severe haemophilia A and healthy boys. CONCLUSION Vascular endothelial growth factor and TIMP-1 can be used for early detection of HA. Further prospective studies should include larger study populations. In addition, studies should address the role of various anti-VEGFs as potential therapy for HA and their impact on prevention and treatment of HA.

Abstract
BACKGROUND Diabetic retinopathy (DR) remains the most common microvascular complication of diabetes; both its high prevalence and associated high risk of vision loss lead it to the major global health burden. Despite significant research efforts, there still remains much of the underlying pathology not fully understand. In the past studies, inner retinal blood flow disturbances are widely assessed as a potential biomarker of DR. However, the results have been variable and even contradictory. Improved methods to figure out the metabolic disturbances associated with DR are essential. Some research showed that both vascular endothelial growth factor-A and blood oxygen saturation are higher in DR patients and correlated with disease severity. Therefore, we decided to conduct a systematic review and meta-analysis to find out the connection of them and provide robust evidence on the mechanism underlying this connection to help us better understand the pathophysiology behind the hypoxic retina and find better ways to treat DR. METHODS This study will be conducted according to Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols. We will do electronic searches from PubMed, EMBASE, Web of Science, Cochrane Library, Wanfang database, CNKI, and VIP database. Two reviewers will screen all the references independently and any disagreement will be solved by the third involvement. All data will be extracted by 2 independent reviewers according to a standardized data extraction sheet. Based on the type of studies, 2 reviewers will independently use different scales to assess the risk of bias. Any disagreements and conflicts will be resolved by discussing it with a third reviewer. We will conduct a random-effects meta-analysis. Individual and pooled odds ratios/relative risks and associated 95% confidence intervals will be calculated as well as between-study heterogeneity. The potential for publication bias will also be evaluated. If possible, we will explore reasons for potential between-study heterogeneity. RESULTS This study is a protocol for systematic review and meta-analysis without results. Associated data analysis will be carried out after the protocol. CONCLUSION The protocol aims to guide a meta-analysis whose purpose is investigating the association between retinal blood oxygen saturation and vascular endothelial growth factors in patients with early DR and trying to find out the mechanism that the changing of retinal oxygen saturation in patients with DR.

Abstract
OBJECTIVE To measure exosomal and plasma levels of candidate blood biomarkers in veterans with history of mild traumatic brain injury (mTBI) and test their relationship with chronic symptoms. METHODS Exosomal and plasma levels of neurofilament light (NfL) chain, tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, and vascular endothelial growth factor (VEGF) were measured using an ultrasensitive assay in a cohort of 195 veterans, enrolled in the Chronic Effects of Neurotrauma Consortium Longitudinal Study. We examined relationships between candidate biomarkers and symptoms of postconcussive syndrome (PCS), posttraumatic stress disorder (PTSD), and depression. Biomarker levels were compared among those with no traumatic brain injury (TBI) (controls), 1-2 mTBIs, and repetitive (3 or more) mTBIs. RESULTS Elevated exosomal and plasma levels of NfL were associated with repetitive mTBIs and with chronic PCS, PTSD, and depression symptoms. Plasma TNF-α levels correlated with PCS and PTSD symptoms. The total number of mTBIs correlated with exosomal and plasma NfL levels and plasma IL-6. Increased number of years since the most recent TBI correlated with higher exosomal NfL and lower plasma IL-6 levels, while increased number of years since first TBI correlated with higher levels of exosomal and plasma NfL, as well as plasma TNF-α and VEGF. CONCLUSION Repetitive mTBIs are associated with elevated exosomal and plasma levels of NfL, even years following these injuries, with the greatest elevations in those with chronic PCS, PTSD, and depression symptoms. Our results suggest a possible neuroinflammatory and axonal disruptive basis for symptoms that persist years after mTBI, especially repetitive.

Abstract
This study aimed to investigate the expression and prognosis of CyclinA and CDK2 in patients with advanced cervical cancer after chemotherapy. The patient history of 108 patients with advanced cervical cancer admitted to our hospital from December 2013 to January 2016 was selected as a cervical cancer group. 54 normal healthy people admitted to our hospital for physical examination in the same period were selected as the control group. Western blotting and RT-PCR were used to detect the difference between CyclinA and CDK2 proteins and mRNA expression between the two groups and the correlation between them was analyzed. The expressions of CyclinA and CDK2 in serum and the changes in detection index level of squamous cell carcinoma antigen (SCCA), carcinoembryonic antigen (CEA) and vascular endothelial growth factor (VEGF) were observed in cervical cancer group at different stages of treatment. The correlation between the two indexes and SCCA, CEA, VEGF and the 3-year survival and prognostic significance of cervical cancer patients with different CyclinA and CDK2 expressions were analyzed. The relative expressions of CyclinA and CDK2 proteins and mRNA in the cervical cancer group were significantly higher than those in the control group (P< 0.05). Pearson correlation analysis showed a positive correlation between CyclinA and CDK2 proteins and mRNA expressions. After treatment, the expressions of CyclinA, CDK2 mRNA and SCCA, CEA and VEGF were significantly lower than those before treatment (P< 0.05). The 3-year survival rate of CyclinA and CDK2 in the high expression group was significantly lower than that of the low expression group. CyclinA and CDK2 are highly expressed in advanced cervical cancer. The expression is decreased after chemotherapy. The prognosis of both low expressions is higher and the expression is good. It can be used to predict the efficacy and prognosis of cervical cancer in the clinic.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Achillea cretica (AC) is a medicinal plant emphasized for treatment of gynecological disorders and pathological symptoms similar to endometriosis in traditional Persian medicine. Since information about its chemical constituents is limited, the aim of this study is to investigate phenolic composition of AC extract as well as its effect on experimental model of endometriosis. MATERIALS AND METHODS RP-HPLC-PDA-ESI-MS/MS analysis was used for the determination of polyphenolic compounds. Endometriosis was induced in rats by suturing of uterus segments to abdominal wall of same rat, after eight weeks when the model was induced, it was followed by 28 days of treatment with 100, 200, and 400 mg/kg/day of hydroethanolic extract of the plant. Blood samples and implanted tissues were collected in the final day, and area of foci, tumor necrosis factor-α, vascular endothelial growth factor, interleukin-6, and serum total thiol molecules were measured and compared with positive group (0.2 mg/kg/day letrozole) and control group (solvent of extract: normal saline). Implanted tissue sections of the sacrificed rats were also assessed histopathologically. RESULTS Nine polyphenolic compounds were identified in AC extract including 7 flavonoids and 2 phenolic acids. Plant extract decreased area of foci and cytokine levels in serum and local tissue. Histopathological assessments confirmed the effectiveness of treatments by decreasing the thickness of epithelial layer and increasing the infiltration of leukocytes into this layer. Doses of 100 mg/kg and 400 mg/kg of extract showed better effects in comparison with the dose of 200 mg/kg in reduction of cytokine levels and size of implanted tissue. Extract and letrozole did not demonstrate significant effect on thiol level. CONCLUSION AC aerial extract may be a favorable medicine for management of endometriosis by modulating inflammatory cytokines; however, further studies are needed for more conclusive and reliable decision about its efficacy and safety.

Abstract
Achieving a biosensing interface without baseline drift caused by variables in matrix samples is essential for real-time detection of analytes. In this study, we developed a molecular beacon based electrochemical aptasensor to realize the ratiometric signal quantification of VEGF in serum by surface modification of nanocomposites of graphene oxide/methylene blue (GO/MB) and AuNPs followed by the attachment of ferrocene-labeled aptamer (aptamer-Fc) against VEGF. The presence of VEGF can trigger the configuration change of aptamer-Fc, resulting in the redox probe Fc being far away from the electrode surface to attenuate the electrochemical communication between electrode and Fc. Meanwhile, signal of MB also decreased due to the impediment of aptamer-Fc to electron transfer passage. The achieved GC-rGO/MB-AuNPs-aptamer-Fc sensing interface was successfully used for the sensitive detection of VEGF in real-time with a linear detection range 2-500 pg mL-1 and detection limit of 0.1 pg mL-1 based on ratiometric dual signal (Fc and MB) read-out. It was observed loading MB and AuNPs to the GO based sensing interface was favorable to enhance the analytical performance in terms of sensitivity and capability to effectively eliminate background interference. This electrochemical aptasensor provides a universal and reliable biosensing platform which is potential for real-time and sensitive tracking of various cytokines in vivo.

Abstract
Objective A randomized controlled trial has shown the efficacy of thalidomide against polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes (POEMS) syndrome; however, there are still refractory patients. We studied the effects of lenalidomide, a derivative of thalidomide, on patients refractory to thalidomide. Methods This prospective single-arm trial evaluated the safety and efficacy of lenalidomide plus dexamethasone in refractory or recurrent patients with POEMS syndrome. The regimen was administered as six 28-day cycles with lenalidomide on days 1-21 (15 mg in cycle 1, and 25 mg in cycle 2-6) plus dexamethasone once a week (20 mg). The primary endpoints were the rate of reduction in the serum vascular endothelial growth factor (VEGF) level at 24 weeks and the incidence of adverse events. This trial was registered with ClinicalTrial.gov, NCT02193698. Results Between July 2014 and December 2015, five men were enrolled. All patients had been refractory to thalidomide plus dexamethasone for more than 24 weeks. The mean rate of reduction in the serum VEGF level at 24 weeks was 59.6%±8.3% (p=0.0003). The mean serum VEGF level decreased from 2,466±771 pg/mL to 974±340 pg/mL. No serious adverse events were observed, and all patients completed six cycles treatment. Discussion Lenalidomide is a therapeutic option for thalidomide-refractory patients with POEMS syndrome.

Abstract
The present study aimed to determine the effect of low-intensity training with blood flow restriction (BFR) on the response rate of anabolic hormones. Forty healthy and untrained young men, aged 18 to 25 years old, were randomly divided into five groups: one session of BFR training (BFR1), two sessions of BFR training (BFR2), one session of resistance training without BFR (WBFR1), two sessions of resistance training without BFR (WBFR2), and the control group (without training). BFR groups had three sets of 20 repetitions with 20-30% 1RM, and none-BFR groups had three sets of 10 repetitions with 70-80% 1RM for six weeks. Both BFR1 and WBFR1 groups trained 3day a week (1 session in a day and three sessions a week), BFR2 and WBFR2 groups trained three days a week (but two sessions a day and six sessions in a week) and Control group did not perform any training. The mean changes in growth hormone(GH), testosterone(TS), and vascular endothelial growth factor (VEGF) hormones were determined by ELISA technique before, after a first training session and after six weeks of the training program. To the analysis of data, two way repeated measures ANOVA at a significant level of P<0.05 also were used. The results showed a significant increase in GH levels in each of the four training groups as compared with the pre-test and the control group after a first training session and after six weeks of the training program (P<0.05). There was no significant increase in TS levels in each of the four training groups, as compared with the pre-test and the control group in both acute and chronic TS response (P>0.05). Only the WBFR1 group did not significantly increase in VEGF levels after the first training session (P>0.05). In chronic VEGF response, there were no significant changes observed in all training groups as compared with the control group(P>0.05). Despite the effectiveness of low-intensity BFR training, such as high-intensity resistance training on hormonal responses, two sessions per day training with the same volume does not necessarily result in larger responses in all hormones than one session per day training.

Abstract
BACKGROUND Patients with coronary chronic total occlusion (CTO) typically have collateralization of the distal vessel, and these collaterals can contribute to the relief of ischemia and anginal symptoms and to the preservation of ventricular function. OBJECTIVES To investigate the preservation effect of coronary collateral circulation on left ventricular (LV) function in coronary CTO, and to explore the potential mechanism behind the development of coronary collateral circulation. MATERIAL AND METHODS A total of 102 consecutive patients with coronary CTO were divided into 2 groups: the left ventricular ejection fraction (LVEF)-preserved group (LVEF ≥ 50%; n = 46) and the LVEF-decreased group (LVEF < 50%; n = 56). Clinical, angiographic and laboratory data was collected for all patients. The association between LVEF and coronary collateral circulation in coronary CTO patients was analyzed with multivariate logistic regression analysis, and the serum levels of VEGF-A and the mRNA expression levels of the VEGF-A gene were compared between different grades of coronary collateral circulation. RESULTS Multivariate analysis revealed that Rentrop grades 2-3 and coexisting collateral pathways were independent predictors of LVEF preservation in coronary CTO patients. Patients with Rentrop grades 2-3 had smaller left ventricular end diastolic diameters (LVDd) and left ventricular end systolic diameters (LVSd), and they had larger LVEFs than the patients with Rentrop grades 0-1. Patients with Rentrop grades 2-3 also had higher serum levels of VEGF-A and higher mRNA expression levels of the VEGF-A gene in their peripheral blood mononuclear cells (PBMCs) than patients with Rentrop grades 0-1. Patients with coexisting collateral pathways had higher serum levels of VEGF-A and higher mRNA expression levels of the VEGF-A gene in PBMCs than patients without coexisting collateral pathways. CONCLUSIONS Coronary collateral circulation is significantly associated with LVEF preservation, and VEGF-A might promote the formation of coronary collateral circulation.

Abstract
BACKGROUND The aim of the study was to provide a theoretical basis for the early diagnosis and prediction of acute altitude sickness, to provide a better entry mode for healthy people from plain areas to plateau areas, and to preliminarily clarify the possible mechanism of this approach. METHODS We measured endothelin-1 (ET-1), asymmetric dimethylarginine (ADMA), vascular endothelial growth factor (VEGF), nitric oxide (NO), and hypoxia-inducible factor 1 (HIF-1) levels in each sample and determined flow-mediated dilation (FMD) values using a portable OMRON color Doppler with a 7.0- to 12.0-MHz linear array probe. We used the Lewis Lake score to diagnose acute mountain sickness (AMS) and to stratify the disease severity. RESULTS We found no cases of AMS at any of the studied elevation gradients. We found significant differences in FMD values between individuals when at 400 m above sea level and when at 2200, 3200, and 4200 m above sea level (P < .05) but found no significant differences among those at 2200, 3200, and 4200 m. Our variance analysis showed that serum ET-1, VEGF, ADMA, NO, and HIF-1 levels in individuals at ≥3000 m and those at subplateau and plain areas (<3000 m) significantly differed (P < .05). The level of these factors also significantly differed between individuals at elevation gradients of plateau areas (3260 m vs 4270 m) (P < .05). We found no significant differences in serum ET-1, VEGF, and ADMA levels between individuals at the plateau (2260 m) and plain (400 m) areas (P > .05). NO and HIF-1 levels were significantly different in serum samples from individuals between the plateau (2260 m) and plain (400 m) areas (P < .05). However, with increasing altitude, the NO level gradually increased, whereas ET-1, ADMA, VEGF, and HIF-1 levels showed a decreasing trend. With the increase of altitude, there is no correlation between the trend of FMD and hematologic-related factors such as VEGF, NO, and HIF-1. CONCLUSION A healthy young male population ascending to a high-altitude area experiences a low incidence of AMS. Entering an acute plateau exposure environment from different altitude gradients may weaken the effect of acute highland exposure on vascular endothelial dysfunction in healthy individuals. Changes in serum ET-1, VEGF, ADMA, NO, and HIF-1 levels in healthy young men may be related to the body's self-regulation and protect healthy individuals from AMS. A short stay in a subplateau region may initiate an oxygen-free preconditioning process in healthy individuals, thereby protecting them from AMS. Noninvasive brachial artery endothelial function test instead of the detection of invasive hematologic-related factors for early diagnosis and prediction of the occurrence and severity of acute high-altitude disease is still lack of sufficient theoretical basis.

Abstract
BACKGROUND Selenium (Se) compounds have demonstrated therapeutic synergism in combination with anticancer treatments whilst reducing normal tissue toxicities in a range of experimental models. While reduction in some toxicities of chemotherapy and radiation has been confirmed in randomised clinical trials, they have not been powered to evaluate improved anticancer efficacy. A lack of data on the clinical potencies of the main nutritionally-relevant forms of Se and the relationship between their pharmacokinetic (PK) profiles and pharmacodynamic (PD) effects in cancer patients has hampered progress to date. The primary objective of this study was to determine the dose and form of Se that can be most safely and effectively used in clinical trials in combination with anti-cancer therapies. STUDY METHODS In a phase I randomised double-blinded study, the PD profile of sodium selenite (SS), Se-methylselenocysteine (MSC) and seleno-l-methionine (SLM) were compared in two cohorts of 12 patients, one cohort with chronic lymphocytic leukaemia (CLL) and the other with solid malignancies. All 24 patients were randomised to receive 400 μg of elemental Se as either SS, MSC or SLM, taken orally daily for 8 weeks. PD parameters were assessed before, during and 4 weeks after Se compound exposure in plasma and peripheral blood mononuclear cells (PBMCs). RESULTS No significant sustained changes were observed in plasma concentrations of vascular endothelial growth factor-α (VEGF-α), expression of proteins associated with endoplasmic reticulum stress (the unfolded protein response) or in intracellular total glutathione in PBMCs, in either disease cohort or when grouped by Se compound. CONCLUSIONS At the 400 μg dose level no substantial changes in PD parameters were noted. Extrapolating from pre-clinical data, the dose examined in this cohort was too low to achieve the Se plasma concentration (≥ 5 μM) expected to elicit significant PD effects. Recruitment of a subsequent cohort at higher doses to exceed this PK threshold is planned.

Abstract
To comprehensively evaluate the pharmacokinetic (PK) characteristics of aflibercept, we established a liquid chromatography with tandem mass spectrometry (LC-MS/MS) method to determine the concentration of vascular endothelial growth factor (VEGF)-A-bound aflibercept and free aflibercept. A specific sample preparation method of nano-surface and molecular-orientation limited (nSMOL) proteolysis was performed to extract both free and bound aflibercept from plasma. The tryptic peptides unique to aflibercept and VEGF-A were selected to quantify the amounts of total aflibercept and aflibercept-VEGF complex, respectively. The method was validated by evaluating its selectivity, linearity, precision, accuracy, extraction recovery, matrix effect, and stability. It was then successfully used to quantify total and bound aflibercept concentrations in cynomolgus monkey plasma, while indirectly obtaining the concentration of free aflibercept by subtraction. The PK results of this LC-MS/MS method are comparable to the traditional enzyme-linked immunosorbent assay (ELISA) results. It is thus a reliable and complementary method for the PK evaluation of aflibercept. Graphical abstract.

Abstract
AIMS The incidence of microvascular complications, including diabetic retinopathy (DR), increases with duration of type 2 diabetes (T2D). Meta-GWAS have reported numerous single-nucleotide polymorphisms (SNPs) associated with T2D; however, no loci, achieving genome-wide significance has been reported for DR. Vascular endothelial growth factor A (VEGFA) and insulin-like growth factor 1 (IGF1) are considered as potential genetic candidates involved in T2D and DR progression. Moreover, the association of serum levels of these proteins with diabetes-related traits is controversial. Therefore, the current study was designed to evaluate the possible genetic predisposition and role of these circulating growth factors in serum in the pathophysiology of T2D and DR. METHODS A cohort of 1126 individuals with T2D was collected including those without retinopathy (DNR = 573), non-progressive diabetic retinopathy (NPDR = 301) and progressive diabetic retinopathy (PDR = 252), and 348 healthy controls. Genomic DNA was isolated, and six SNPs: rs833061, rs13207351, rs1570360, rs2010963, rs5742632 and rs6214, were genotyped and results statistically analyzed. ELISA was performed on a subset of the samples to measure serum levels of IGF1 and VEGFA. RESULTS The minor allele of rs6214 was associated with T2D [OR = 1.67 (95% CI 1.39-2.01, p = 4.9E-8)], rs13207351 was associated with NPDR [OR = 1.97 (95% CI 1.28-3.03, p = 9.0E-3)]when compared with DNR, and rs5742632 showed positive association with PDR [OR = 1.66 (95% CI 1.33-2.05, p = 1.0E-4)] compared to DNR. Lowered IGF1 serum levels were found to be associated with T2D, NPDR and PDR. CONCLUSIONS IGF1 was found to increase the T2DM susceptibility as well as advanced DR, i.e., PDR, while VEGFA was found to be associated with early DR stage, i.e., NPDR.

Abstract
Background The acute respiratory distress syndrome (ARDS) is characterized by pulmonary epithelial and endothelial barrier dysfunction and injury. In severe forms of ARDS, extracorporeal membrane oxygenation (ECMO) is often the last option for life support. Endothelial progenitor (EPC) and mesenchymal stem cells (MSC) can regenerate damaged endothelium and thereby improve pulmonary endothelial dysfunction. However, we still lack sufficient knowledge about how ECMO might affect EPC- and MSC-mediated regenerative pathways in ARDS. Therefore, we investigated if ECMO impacts EPC and MSC numbers in ARDS patients. Methods Peripheral blood mononuclear cells from ARDS patients undergoing ECMO (n = 16) and without ECMO support (n = 12) and from healthy volunteers (n = 16) were isolated. The number and presence of circulating EPC and MSC was detected by flow cytometry. Serum concentrations of vascular endothelial growth factor (VEGF) and angiopoietin 2 (Ang2) were determined. Results In the ECMO group, MSC subpopulations were higher by 71% compared to the non-ECMO group. Numbers of circulating EPC were not significantly altered. During ECMO, VEGF and Ang2 serum levels remained unchanged compared to the non-ECMO group (p = 0.16), but Ang2 serum levels in non-survivors of ARDS were significantly increased by 100% (p = 0.02) compared to survivors. Conclusions ECMO support in ARDS is specifically associated with an increased number of circulating MSC, most likely due to enhanced mobilization, but not with a higher numbers of EPC or serum concentrations of VEGF and Ang2.

Abstract
BACKGROUND AND AIMS The purpose of this study was to investigate whether an intervention with physical activity (PA) would promote positive effects on the angiogenic factors, mobilization, and functionality of circulating endothelial progenitor cells (EPCs) in children with low birth weight (LBW). METHODS AND RESULTS Thirty-five children participated in a 10-week PA program (intensity: 75-85% of heart rate reserve, frequency: four times/week, and duration: 45 min). Before and after the PA program, we evaluated anthropometric parameters, blood pressure levels, biochemical profile, number of EPCs, number of EPC colony forming units, and plasma levels of vascular endothelial growth factor-A (VEGF-A), nitric oxide (NO), and matrix metalloproteinases (MMPs) 2 and 9. We found a significant main effect of the PA program on waist circumference (ηp2 = 0.489), cardiorespiratory fitness (ηp2 = 0.463), and MMP-9 (ηp2 = 0.582). Birth weight or the PA program produced significant independent effects on systolic blood pressure (birth weight: ηp2 = 0.431; PA program: ηp2 = 0.615) and EPC colony forming units (birth weight: ηp2 = 0.541; PA program: ηp2 = 0.698) with no significant interactions. The combination of birth weight and the PA program produced a significant interaction effect on the number of circulating EPCs (ηp2 = 0.123), NO (ηp2 = 0.258), and VEGF-A (ηp2 = 0.175). The variation in the number of EPCs from baseline to 10 weeks of the PA program correlated positively with the change in NO (P = 0.002) and VEGF-A (P = 0.004). CONCLUSIONS A 10-week PA program attenuates the adverse effect of LBW on the number and functionality of EPCs; this effect occurs through an improvement in circulating levels of NO and VEGF-A.

Abstract
The aim of this systematic review is to evaluate whether the use of probiotics has any effect on the components of metabolic syndrome (MetS) before patients develop type 2 diabetes. A qualitative systematic review, following the Cochrane methodology, and a comprehensive literature search of randomized controlled trials (RCTs) were conducted in PubMed and Scopus from inception until 4 July 2019. According to our inclusion criteria, nine clinical studies were finally analyzed, corresponding to six RCTs. Probiotics intake in patients with MetS resulted in improvements in body mass index, blood pressure, glucose metabolism, and lipid profile in some studies. Regarding inflammatory biomarkers, probiotics also positively affected the soluble vascular cell adhesion molecule 1 (sVCAM-1), interleukine-6 (IL-6), tumor necrosis factor α (TNF-α), vascular endothelial growth factor (VEGF), and thrombomodulin. Despite the diversity of the published studies, the intake of probiotics for patients with MetS may offer a discrete improvement in some of the clinical characteristics of the MetS and a decrease in inflammatory biomarkers. Nevertheless, these beneficial effects seem to be marginal compared to drug therapy and a healthy lifestyle and clinically non-relevant.

Abstract
Nuclear receptor coactivators (NCOAs), consisting of coactivators and corepressors, dramatically enhance the transcriptional activity of nuclear receptors. Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor that plays a major role under hypoxic conditions. This study was performed with the focus on the association of NCOAs with HIF-1α in the serum of chronic kidney disease (CKD) patients. Sixty patients with stage 5 CKD and 30 healthy controls from The Second Affiliated Hospital of Shantou University Medical College, between March 21, 2019, and October 30, 2019, were recruited in this prospective cohort study. We analyzed the serum levels of NCOAs (NCOA1, NCOA2, and NCOA3), HIF-1α, vascular endothelial growth factor (VEGF), etc. and assessed whether there was any relationship between these parameters and CKD disease. We found that circulating NCOA1 was positively associated with circulating NCOA2, NCOA3, and HIF-1α. A positive correlation was also observed between NCOA2 and NCOA1, NCOA3, HIF-1α, and VEGF. Furthermore, statistically significant correlations between NCOA3 and NCOA1, NCOA2, and HIF-1α were observed. The serum levels of VEGF in the CKD group were higher than those of the healthy control group. Circulating NCOA1 and circulating NCOA2 were negatively associated with procalcitonin. In conclusion, there was an association between circulating NCOA1, NCOA2, NCOA3, and circulating HIF-1α, and circulating VEGF was a risk factor for CKD disease. However, more studies should be performed to confirm this hypothesis.

Abstract
PURPOSE To evaluate the effect of transcatheter arterial chemoembolization (TACE) under the guidance of contrast-enhanced ultrasound (CEUS) in patients with advanced hepatocellular carcinoma (HCC). METHODS One hundred and sixty patients with HCC admitted to Cangzhou Central Hospital from April 2015 to April 2017 were enrolled. The clinical data were retrospectively analyzed. Seventy-five patients who underwent TACE according to CEUS results were selected as the observation group. The remaining 85 cases that underwent digital subtraction augiography (DSA) angiography-guided TACE were selected as the control group and were intravenously infused with 15 mg of Endostar+500 mL of normal saline once a day for 3 consecutive days (Endostar 30 mg was reperfused during the operation). Both groups were re-contrasted at 1 month (T2) and 3 months (T3) to determine whether TACE was performed again. The numbers of TACEs re-performed were recorded. Color Doppler energy imaging was used to observe the neovascularization of the tumor. The changes of serum vascular endothelial growth factor (VEGF) and CRP levels were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS There were significant differences in the number of TACEs re-performed between the observation group and the control group (p<0.05). The serum VEGF level in the observation group was always lower than that in the control group (p<0.05). CRP levels in the control group showed an upward trend. The serum CRP level in the control group was significantly higher compared to the observation group at T3. The number of grades 0 and 1 neovascularization in the control group was significantly lower than in the observation group. The neovascularization rate of the observation group was significantly higher than the control group; the tumor effective rate of the observation group was not different from that of the control group, but the disease control rate was higher than in the control group. CONCLUSION CEUS-guided TACE treatment of HCC can effectively inhibit tumor angiogenesis, control tumor progression, and prolong the survival of patients, which is conducive to the prognosis of patients.

Abstract
BACKGROUND Metformin has been reported to decrease insulin resistance and is associated with a lower risk of pregnancy-induced hypertension and preeclampsia. It is widely accepted that the placenta plays a crucial role in the development of preeclampsia. Our aim is to explore the effect of metformin on preeclampsia. STUDY DESIGN We examined control diet-fed (isocaloric diet) pregnant mice (CTRL group), pregnant mice fed a high-fat diet (HF group), and high-fat-diet-fed pregnant mice treated with metformin (HF-M group). The HF mice were fed a high-fat diet six weeks before pregnancy to establish a preeclampsia-like model; then, the group was randomly divided into a HF group and a HF-M group after pregnancy. Blood pressure, urine protein, pregnancy outcomes, protein expression, and histopathological changes in the placentas of all groups were examined and statistically analysed. RESULTS We observed that metformin significantly improved high blood pressure, proteinuria, and foetal and placental weights in the HF-M group compared with the HF group. Metformin significantly improved placental labyrinth and foetal vascular development in preeclampsia. In addition, metformin effectively increased matrix metalloproteinase-2 (MMP-2) and vascular endothelial growth factor (VEGF) levels in the placenta. CONCLUSIONS Our results suggest that metformin can improve preeclamptic symptoms and pregnancy outcomes.

Abstract
ETHNOPHARMACOLOGICAL EVIDENCE Pulmonary fibrosis (PF) is a progressive disease characterized by the aberrant accumulation of fibrotic tissue in the lungs parenchyma, associated with significant morbidity. Few effective drugs have been developed to reverse PF or even halt the disease progression. Yangfei Huoxue Decoction (YHD), a Traditional Chinese Medicine, which consisted of Astragalus membranacus(AM), Glehnia littoralis(GL), Schisandra chinensis(SC), Salvia miltiorrhiza Bunge(SB), Reynoutria japonica(RJ), Ligusticum chuanxiong(LX), and Euonymus alatus(EA) , has been used in China for the treatment of PF for many years with remarkable efficacy. According to the clinic observation of the results, we conducted experiments on animals, the process of BLM-induced pulmonary fibrosis in rats was interfered by YHD, through the detection of pulmonary fibrosis rats' blood cells and plasma, we selected the related molecules that may exert proinflammatory(IL-1β), promote angiogenesis(vascular endothelial growth factor ,VEGF). For further explicitly research, we should know what the chemical composition the prescription (YHD) contains and what the related bioactive components have. In accordance with in-house library and evaluating the characteristic MS fragmentation patterns, the schisandra chinensis methanol, lignin, flavonol, polyphenol, tanshinone, salvianolic acid, anthraquinone, ligustrazine, etc. had a retardant and inhibitory effect on the development and formation of pulmonary fibrosis. These results will aid in the quality control of YHD, as well as provide fundamental data for further pharmaco-mechanisms studies. AIM OF THE STUDY To discover the pulmonary immune related bioactive components of YHD. MATERIALS AND METHODS Animal Experiment:144 SD rats, based on the principles of randomization divided into eight groups, Control group, bleomycin(BLM) group, BLM + dexamethasone(BLM + DXM) group, BLM + Yangfei(YF) group, BLM + Huoxue(HX) group, BLM + high-doseYHD(YHD-H) group, BLM + medium-doseYHD(YHD-M) group, and BLM + low-doseYHD(YHD-L) group, each group of 18 rats. After endotracheal administration of Bleomycin by tracheotomy, rats were sacrificed on day 7, day 14 and day 28, blood and plasma were taken at the same time. Respectively, the VEGF, an immune molecule associated with angiogenesis, and IL-1β in plasma were detected by ELISA at three time periods. Component testing: 100 g YHD were constituted of SB 15 g, LX 12 g, EA 10 g, RJ 15 g, AM 20 g, GL 20 g and SC 8 g. All herbs were obtained from Beijing Tong Ren Tang (Group) Co ltd. The voucher specimens were identified by Prof. Jiening Gong (Nanjing University of Chinese Medicine). YHD were extracted by sonication with 1 L ethanol/water (70:30, v/v) for two cycle (1 h per cycle) at room temperature. The combined extracts were filtered, condensed, and reconstituted with 50 mL methanol before analysis. Standard Cianidanol, Ferulic Acid, Polydatin, Calycosin 7-O-glucoside, Tanshinone IIA, Salvianolic acid B, Schizandrol A, and Isoimperatorin were prepared in methanol. After centrifuging at 20,000 rpm for 10 min, 4 μL supernatant was injected into the Ultra-Performance Liquid Chromatography coupled with Quadrupole Time-of-Flight tandem mass spectrometry (UPLC/QTOF-MSE) combined with UNIFI informatics platform for analysis. CONCLUSION The experiment results revealed that the vascularized VEGF, inflammatory factor expression of IL-1β was restrained by YHD. The UPLC/QTOF-MSE method, an automatic database screening platform and the characteristic MS fragmentation patterns have efficiently facilitated the post data process, so we test for the identification of major components in YHD by this technology, more than seven or more active ingredients, the results showed that YHD contained a total of 55 components, including 11 lignans, 12 flavonoids, 7 tanshinones, 9 organic acid, 5 polyphenols, 4 anthraquinones, 5 senkyunolides and 2 others. Based on this, we can ensure the discovery and analysis of biologically active compounds in YHD, as well as provide a reference for the quality evaluation. We expect the method presented here could be applied to other multi-component TCM formula. In addition, we can conduct more in-depth research, such as mechanism research, molecular detection, gene target and so on.

Abstract
OBJECTIVE The objective of this work was to study the effect of the combined action of X-radiation and the cyclooxygenase-2 (COX-2) inhibitor on the level of vascular endothelial growth factor (VEGF) and prostaglandin E2 (PGE-2) in blood serum of rat-tumor carriers at irradiation in different doses. MATERIALS AND METHODS 20 tumor-bearing rats of the Wistar population weighing 160-180 g, with transplanted Guerin carcinoma, fractionated irradiation (5 Gy + 5 Gy) and (0.5 Gy + 0.5 Gy) of the tumor growth zone on the RUM- 17 was carried out, with an interval between sessions of 24 hours. The drug «Meloxivet» - a selective inhibitor of cyclooxygenase-2 was administered 24 hours before irradiation and 2 hours before the second exposure (0.2 mg per 1 kg body weight). Blood sampling was performed by the method of life-time decapitation after 24 hours after the last fraction of irradiation. The content of VEGF in blood serum was determined by the method of enzyme immunoas- say using standardResults. After fractionated irradiation in a total dose of 1 Gy (0.5 Gy + 0.5 Gy), the level of VEGF was increased by 1.5 times compared with intact control, and in animals that were irradiated in a total dose of 10 Gy (5 Gy + 5 Gy ), the VEGF level was reduced by 1.92 times. That is, there was a difference in the content of VEGF in blood serum of rat tumor carriers, depending on the dose of irradiation: in a total dose of 1 Gy - stimulation of angiogenesis, and in the total dose of 10 Gy - a significant slowdown in this process. In the case of combined exposure to radiation (10 Gy) and the COX-2 inhibitor, meloxivet, the potential decrease in VEGF levels was 3.49 times compared to con- trol and 1.8 times with isolated exposure. At the same time, the level of PGE-2 also decreased with respect to iso- lated exposure by 1.5 times, indicating COX-2 inhibition. With a combined low dose (1 Gy) irradiation and COX-2- meloxivet inhibitor, VEGF levels were reduced by 1.1 times compared to control and 1.7 times relative to isolated exposure. At the same time, the level of PGE-2 also decreased in comparison with isolated radiation in 1,1 times. The obtained results indicate the influence of the combined act of irradiation and meloxivet on the level of VEGF and PGE-2, which causes the antiangiogenic effect.Сonclusions. It has been shown that low doses of ionizing radiation (1 Gy) and high doses (10 Gy) have a different effect on VEGF expression, and thus on angiogenesis processes. The combined effect of ionizing radiation and the COX-2 inhibitor (meloxivet) affects the level of PGE-2, VEGF, ie, the slowing of angiogenesis. In the case of large doses of exposure, this effect is even more expressed.

Abstract
This paper presents the first CMOS Vascular Endothelial Growth Factor (VEGF) sensor for cancer diagnosis directly from human blood. The sensor incorporates a peptide aptamer-based microneedle that allows the detection of electrochemical reactions with VEGF. This results in a capacitance change between the microneedles and then reads out by a two-step capacitance-to-digital converter (CDC). The proposed two-step CDC consists of a coarse 5b slope ADC and a fine 14b continuous-time delta-sigma modulator (CTDSM). During slow peptide-binding, the slope ADC performs a coarse conversion and the results are used to adjust the current level of the stimulator. After settling of the peptide-binding, based on an adjusted stimulation current, the CTDSM measures the small capacitance changes of the sensor. The prototype chip is fabricated in a 65-nm CMOS process, occupying a 0.87 mm 2 active area. The power consumption is 270 muW. Thanks to the two-step approach, this work achieves a wide dynamic range of 18.3b, covering a large sensor-to-sensor variation. It also achieves a peak resolution of 13.7b, while maintaining errors in 1 to 100 nF baseline capacitance. The overall sensor system successfully detects the VEGF in both phosphate-buffered saline (PBS) and human blood serum. Without the use of precision instruments, this work achieves a resolution of 15 fM [Formula: see text] in range of 0.1 to 1000 pM and denotes the clear VEGF selectivity at 40× in PBS and 5× in the blood serum compared to other proteins (IgG, Con A, and cholera toxin).

Abstract
PURPOSE Aflibercept is a targeted anti-VEGF therapy used to treat patients with metastatic colorectal cancer (mCRC) following progression on oxaliplatin-based regimens. This post hoc study evaluated the effect of prior bevacizumab treatment and growth factor levels on patient outcomes associated with aflibercept in the VELOUR phase III trial. EXPERIMENTAL DESIGN Baseline biomarker plasma concentrations were measured using a bead-based multiplex assay. Patients were grouped according to prior bevacizumab treatment, second-line treatment, and serum biomarker concentrations, and analyzed for overall survival (OS) and progression-free survival (PFS). RESULTS Plasma samples were available for 553 patients (placebo n = 265; aflibercept n = 288), of which 169 had received prior bevacizumab. Nine biomarkers implicated in angiogenesis or bevacizumab resistance correlated with prior bevacizumab therapy. VEGF-A and placental growth factor (PlGF) were the most significantly increased in patients who had received prior bevacizumab compared with those who had not received prior bevacizumab. In the placebo group, patients with high VEGF-A (>144 pg/mL) levels at baseline had worse OS and PFS compared with patients with lower levels at baseline (9.6 vs. 12.9 months). This was also seen in patients who received placebo and had high baseline PlGF (>8 pg/mL; 9.7 vs. 11.7 months). In the aflibercept group, prolonged OS and PFS were observed regardless of baseline VEGF-A or PlGF levels. CONCLUSIONS High VEGF-A and PlGF serum levels may underlie development of resistance to bevacizumab in patients with mCRC. Aflibercept retains its activity regardless of baseline VEGF-A and PlGF levels and may be an effective second-line treatment for patients with bevacizumab-induced resistance.

Abstract
PURPOSE To evaluate the effect of transcatheter arterial chemoembolization (TACE) under the guidance of contrast-enhanced ultrasound (CEUS) in patients with advanced hepatocellular carcinoma (HCC). METHODS One hundred and sixty patients with HCC admitted to Cangzhou Central Hospital from April 2015 to April 2017 were enrolled. The clinical data were retrospectively analyzed. Seventy-five patients who underwent TACE according to CEUS results were selected as the observation group. The remaining 85 cases that underwent digital subtraction augiography (DSA) angiography-guided TACE were selected as the control group and were intravenously infused with 15 mg of Endostar+500 mL of normal saline once a day for 3 consecutive days (Endostar 30 mg was reperfused during the operation). Both groups were re-contrasted at 1 month (T2) and 3 months (T3) to determine whether TACE was performed again. The numbers of TACEs re-performed were recorded. Color Doppler energy imaging was used to observe the neovascularization of the tumor. The changes of serum vascular endothelial growth factor (VEGF) and CRP levels were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS There were significant differences in the number of TACEs re-performed between the observation group and the control group (p<0.05). The serum VEGF level in the observation group was always lower than that in the control group (p<0.05). CRP levels in the control group showed an upward trend. The serum CRP level in the control group was significantly higher compared to the observation group at T3. The number of grades 0 and 1 neovascularization in the control group was significantly lower than in the observation group. The neovascularization rate of the observation group was significantly higher than the control group; the tumor effective rate of the observation group was not different from that of the control group, but the disease control rate was higher than in the control group. CONCLUSION CEUS-guided TACE treatment of HCC can effectively inhibit tumor angiogenesis, control tumor progression, and prolong the survival of patients, which is conducive to the prognosis of patients.

Abstract
Seasonal variations have recently been described in biomarkers, cell types, and gene expression associated with the immune system, but so far no studies have been conducted among women in the peripartum period. It is of note that pregnancy complications and outcomes, as well as autoimmune diseases, have also been reported to exhibit seasonal fluctuations. We report here a clear-cut seasonal pattern of 23 inflammatory markers, analysed using proximity-extension assay technology, in pregnant women. The inflammatory markers generally peaked in the spring and had a trough in the autumn. During the postpartum period we found seasonality in one inflammatory marker, namely monocyte chemotactic protein 4 (MCP-4). Our findings suggest that seasonal variations in peripheral inflammatory markers are only observed during pregnancy. The results of this study could be valuable to professionals working within the field of immunology-related areas, and provide insight for the understanding of obstetric complications.

Abstract
BACKGROUND Non-healing wounds are becoming a growing concern for public health as a result of their increasing prevalence in progressively aging societies. OBJECTIVES The aim of this article is to evaluate the effects of wound etiology on a panel of circulating cytokines in patients with non-healing wounds of the lower extremities. MATERIAL AND METHODS This prospective case-control study involved 104 individuals: healthy elderly people (n = 46) and patients with diabetes and/or cardiovascular disease (n = 58; among them 38 with chronic wounds of venous, ischemic or neurotrophic etiology). Selected serum cytokines - i.e. IL-1β, IL-4, IL-6, IL-8, FGF-2, G-CSF, GM-CSF, MCP-1, MIP-1α, TNF-α, VEGF-A, and PDGF-BB - were measured using the Luminex platform. RESULTS Compared to healthy elderly people, presence of diabetes and/or cardiovascular disease was associated with elevated IL-6, IL-8, MCP-1 and G-CSF while non-healing wounds coexisted with the increase in the levels of all examined cytokines/growth factors except for G-CSF and GM-CSF. Among diseased elderly people, having wounds was associated with increased levels of IL-1β, IL-4, IL-6, IL-8, FGF-2, MIP-1α, PDGF-BB, and VEGF-A. Interleukin 1β elevation was a sole independent predictor of chronic wounds with an odds ratio (OR) of 6.3. Cytokines in healthy seniors were loosely interrelated, while the levels of cytokines in diseased patients with wounds displayed a tight pattern of association. When stratified by their etiology, the association pattern for IL-6, IL-8, MCP-1, and VEGF-A was disrupted in neurotrophic wounds. CONCLUSIONS The results presented herein may improve our understanding of the pathomechanisms which lead to chronic wounds and of the effects they exert on a systemic level, as well as providing potential targets for more effective therapies.

Abstract
Rheumatoid arthritis (RA) is a chronic and progressive autoimmune inflammatory disease associated with irreversible joint destruction that leads to permanent motor disability and compromised quality of life. However, the main cause of RA is still unknown though stimulation of immune system and cells plays pivotal role in disease development and progression. Ramucirumab (RAM) is the monoclonal antibody against VEGF- receptor. This study aimed to investigate and evaluate the therapeutic effect of RAM with or without Methotrexate (MTX) against adjuvant-induced arthritis in rats. Complete Freund's adjuvant (CFA)-induced arthritic rats were treated for three consecutive weeks with MTX or RAM alone and MTX-RAM co-therapy. Arthritic score, gait score, ankle diameter, paw thickness, angiogenic, inflammatory cytokines, bone erosion markers, and apoptotic markers were assessed to evaluate the anti-arthritic effect. RAM monotherapy exhibited anti-inflammatory, anti-angiogenic and anti-apoptotic effects similar to MTX alone to treat RA in the current study. Furthermore, RAM alone had a protective effect on bone and cartilage health better than standard anti-rheumatic agent MTX. Interestingly, combined therapy of MTX and RAM produced significant differences in comparison with MTX or RAM monotherapy in all tested parameters. Moreover, the current study proved that MTX-RAM co-therapy has a synergistic effect.

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
Objective TAFRO syndrome is rare, and its underlying mechanisms currently remain unknown. Furthermore, standard therapeutic strategies have yet to be established. One of the hallmarks of TAFRO is pathological hypercytokinemia, which involves vascular endothelial growth factor (VEGF). A correlation has been reported between elevated VEGF and TSH levels in patients with hypothyroidism. Although hypothyroidism is a common endocrine abnormality, its clinical significance in TAFRO syndrome remains unclear. Methods and Patients We investigated six patients diagnosed with TAFRO syndrome and examined their thyroid function in detail to obtain a deeper understanding of its relationship with cytokines and the manifestations of thyroid abnormalities as well as their clinical significance in TAFRO syndrome. Results Five patients had subclinical hypothyroidism, while one had clinical hypothyroidism. Plasma VEGF levels were elevated in all patients, with a mean level of 256 pg/mL. Treatment with thyroxine supplements and immunotherapy or chemotherapy improved the symptoms of TAFRO syndrome without recurrence as well as increased the VEGF levels in three patients. Conclusion The present results suggest that subclinical hypothyroidism may be a potential factor in the pathogenesis and symptomatology of TAFRO syndrome with VEGF elevation.

Abstract
Diosmin is a natural compound with a wide range of biological activity, e.g., it improves lymphatic drainage, supports microcirculation, and increases venous tone, and venous elasticity, hence, it is applied in the pharmacotherapy of chronic venous disorders (CVD). The aim of this study was to assess the correlation between diosmin administration (2 × 600 mg daily) in patients suffering from CVD and the levels of selected factors influencing angiogenesis, which are involved in CVD pathophysiology. Thirty-five CVD patients were examined. Levels of plasma tumor necrosis factor alpha (TNF alpha), vascular endothelial growth factor (VEGF-A and VEGF-C); angiostatin, interleukin 6 (IL-6), fibroblast growth factor 2 (FGF2); and plasminogen (PLG) were measured with an Elisa assay before and after three months of diosmin administration. The clinical symptoms of CVD were monitored using ultrasound images, echo Doppler assay, visual analogue scale (VAS), and measurement of the leg circumference. The average content of TNF alpha, VEGF-C, VEGF-A IL-6, and FGF2 decreased after the therapy with diosmin in a significant manner; with p < 0.001, p < 0.05, p < 0.05, p < 0.01, and p < 0.01, respectively, and a significant (p < 0.05) increase in the plasma angiostatin level after the three-month treatment was found. A significant (p < 0.05) decrease in edema and the average leg circumference of the patients was observed after the therapy. Diosmin influences the angiogenic and inflammatory mechanisms involved in the pathophysiology of edema presented in patients with a different class of CVD.

Abstract
BACKGROUND To determine the impact of HTRA1 rs1120638, TIMP3 rs9621532, VEGFA rs833068, CFI rs10033900, ERCC6 rs3793784, and KCTD10 rs56209061 genotypes on the development of age-related macular degeneration (AMD) in the Lithuanian population. METHODS A total of 916 subjects were examined: 309 patients with early AMD, 301 patients with exudative AMD, and 306 healthy controls. The genotyping of HTRA1 rs11200638, TIMP3 rs9621532, VEGFA rs833068, CFI rs10033900, ERCC6 rs3793784, and KCTD10 rs56209061 was carried out using the RT-PCR method. RESULTS Our study showed that single-nucleotide polymorphisms rs3793784 and rs11200638 were associated with increased odds of early and exudative AMD, and the variant in KCTD10 (rs56209061) was found to be associated with decreased odds of early and exudative AMD development after adjustments for age and gender in early AMD analysis and after adjustments only for age in exudative AMD. The haplotype containing two minor alleles C-A and the G-A haplotype in rs3793784-rs11200638 were statistically significantly associated with an increased risk of exudative AMD development after adjustment for age, while the G-G haplotype showed a protective role against early and exudative AMD and the haplotype C-G in rs3793784-rs11200638 was associated with a decreased risk only of exudative AMD development. CONCLUSIONS Our study identified two markers, rs11200638 and rs3793784, as risk factors for early and exudative AMD, and one marker, rs56209061, as a protective factor for early and exudative AMD development. The haplotypes constructed of rs3793784-rs11200638 were found to be associated with AMD development, as well.

Abstract
Although cardiac involvement is rare in polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes (POEMS) syndrome, the clinical course becomes considerably worse on complication with cardiac lesions. The increased release of various cytokines has been observed in the pathogenesis of POEMS syndrome, and serum vascular endothelial growth factor (VEGF) levels are known to be associated with the disease activity. We herein report a patient with POEMS syndrome who showed left ventricular systolic dysfunction and was treated with lenalidmide therapy. Of note, the reduction in extracellular edema in the left ventricular wall was clearly visualized by changes in the native T1 values and extracellular volumes on cardiac magnetic resonance imaging.

Abstract
PURPOSE The endothelin system is involved in the evolution of multiple malignancies, participating in cancer cell proliferation, tumor invasion and angiogenesis. Our purpose was to simultaneously assess endothelin expression in the systemic circulation of patients with lobular neoplasia (LN) of the breast and to investigate its correlation with vascular endothelial growth factor (VEGF) specimen expression levels as well as clinicopathologic findings. METHODS This was a retrospective analysis of prospectively collected data regarding 60 women examined in a single breast unit. Thirty of these women underwent stereotactic biopsy and were diagnosed with LN and the remaining 30 were healthy controls. Circulating levels of endothelin (ET)-1 and Big ET-1 were measured using ELISA, while tissue expression of ET-1 and VEGF in biopsy specimens were assessed using qualitative immunohistochemical staining. RESULTS The plasma levels of Big ET-1 were significantly increased in patients with LN compared to healthy controls. There was no significant difference in the plasma levels of ET-1 between the patient groups. In patients with LN, plasma expression of ET-1 and Big ET-1 did not correlate with ET-1 or VEGF tissue expression status, neither existed a relationship between tissue expressions of ET-1 and VEGF. CONCLUSIONS Our results imply that Big ET-1 is a potential biomarker for LN. Further investigation of the endothelin system role in LN seems a promising research field.

Abstract
INTRODUCTION AND AIM Microangiopathy is a hallmark of systemic sclerosis (SSc). It is a progressive process from an early inflammatory and proangiogenic environment to insufficient microvascular repair with loss of microvessels. The exact underlying mechanisms remain ill-defined. Aim of the study was to investigate whether imbalanced angiopoietins/VEGF serum profile should be related in SSc to the altered microvascular reactivity characterized by aberrant angiogenesis and avascularity. MATERIALS AND METHODS Serum levels of Angiopoietin-1 (Ang1), Angiopoietin-2 (Ang2) and VEGF were measured by ELISA in 47 SSc patients and 27 healthy controls. Microvascular alterations were assessed by nailfold videocapillaroscopy (NVC). RESULTS Serum concentrations of Ang1 were significantly lower [mean (S.D.): 21516.04 (11,441.035) pg/ml], and Ang2 significantly increased [25,89.55 (934.225) pg/ml] in SSc as compared with the control group [Ang1: 28,457.08 (10,431.905) pg/ml; Ang2: 1556.23 (481.255) pg/ml, p < 0.01, respectively], whereas VEGF did not differ significantly. The ratios of Ang1/Ang2 and Ang1/VEGF were significantly lower in SSc patients (8.346 ± 4.523 and 95.17 ± 75.0, respectively) than in healthy subjects (17.612 ± 6.731 p < 0.000001 and 183.11 ± 137.73; p = 0.004]. Formation of giant capillaries with vascular leakage and collapse was associated with significant increase in VEGF and concomitant Ang1 deficiency. Capillary loss was related to significant increase in VEGF with respect to those with preserved capillary number (395.12 ± 256.27 pg/mL vs. 254.80 ± 213.61 pg/mL) whereas elevated Ang2 levels induced more advanced capillary damage as indicated by the presence of the "Late" NVC pattern. CONCLUSIONS We found that serum levels of Ang1, Ang2 and VEGF are differentially expressed in SSc and altered Ang1/Ang2 profile might underlay the aberrant angiogenesis in SSc despite increase in VEGF. For the first time we identified that significant deficiency of Ang1 might be involved in early capillary enlargement, followed by collapse and lack of stable newly-formed vessels in VEGF-enriched environment, whereas Ang2 levels seem to increase later in disease progression and advanced microvascular damage ("Late" NVC pattern).

Abstract
Proper vascular function is important for well-being of mother and growing fetus. VEGFTOTAL, and VEGF165b levels and its vascular endothelial complications in gestational diabetes mellitus (GDM) together with the association of inflammation and advanced glycation end products (AGEs) are less studied. VEGF165b/VEGFTOTAL (VEGF RATIO) in GDM pregnant women was investigated in this study. Plasma VEGFTOTAL was lower in GDM (17.68 ± 1.30 pg/mL) compared to non-GDM (25.69 ± 1.40 pg/mL). VEGF165b, ICAM-1, and AGEs were higher in GDM (9.9 ± 1.4 pg/mL, 201.04 ± 7.85 µg/mL, and 10.40 ± 0.98 µg/mL, respectively) and lower in non-GDM (6.47 ± 0.70 pg/mL, 174.1 ± 7.11 µg/mL, and 4.71 ± 0.39 µg/mL, respectively). Compared to non GDM (0.25 ± 0.02), VEGF RATIO was higher in GDM (0.45 ± 0.04) and correlated with -ICAM-1 (r = 0.375, p < .001) and AGEs (r = 0.199, p < .05). Tertile stratification of VEGF RATIO implied that frequency of GDM increases with increasing tertiles of VEGF RATIO (p for trend <.001). Association of VEGF RATIO with GDM was significant even after adjusting for AGEs (OR = 1.279, CI = 1.118-1.462, p < .0010) but it lost its significance when adjusted for ICAM-1 (OR = 1.006, CI = 0.995-1.017, p = .308). VEGF RATIO plays an important role in GDM in association with vascular inflammation.

Abstract
OBJECTIVE To evaluate ocular and general safety of topical anti-human VEGF bevacizumab and the effect on serum vascular endothelial growth factor (VEGF) values in healthy dogs. PROCEDURES Nine university-owned beagles received 0.05 mL of 0.25% bevacizumab eyedrops (Avastin® , Roche) in one eye and 0.05 mL of 0.9% saline solution in the other eye as a control, administered at 12 hours intervals over a period of 28 days. Continuous monitoring for vital parameters and ocular examinations were conducted. Complete blood counts including hematology and coagulation parameters were performed before trial start as well as 24 hours, 7 days, and 28 days after trial start. Measurements of serum VEGF values were obtained using an ELISA-based approach at days 0, 7, and 28. The experiment was designed as a masked placebo-controlled study. RESULTS No clinical signs of ocular toxicity or systemic incompatibility were noted in any dog at any time point of the study. No signs of pain were present in any dog at any time point. All blood count values remained in normal clinical ranges without relevant variation. There was no significant change in mean serum VEGF values between day 0 and day 7 and between day 0 and day 28. CONCLUSIONS The results indicate that topical bevacizumab treatment is safe in healthy dogs. However, further studies are needed to assess safety and efficacy in diseased dogs with naturally occurring corneal neovascularization.

Abstract
Objective Detection of vascular endothelial growth factor (VEGF) levels in ocular tissue may perhaps provide insight into the role of VEGF in the pathogenesis and progression of diabetic retinopathy (DR). The aim of this study was to evaluate the levels of VEGF in tears and serum amongst type 2 diabetes mellitus (DM) patients. Methods A comparative cross-sectional study was conducted between August 2016 and May 2018 involving type 2 DM patients with no DR, non-proliferative DR (NPDR), and proliferative DR (PDR). Tear samples were collected using no.41 Whatman filter paper (Schirmer strips) and 5 mL blood samples were drawn by venous puncture. VEGF levels in tears and serum were measured by enzyme-linked immunosorbent assay. Results A total of 88 type 2 DM patients (no DR: 30 patients, NPDR: 28 patients, PDR: 30 patients) were included in the study. Mean tear VEGF levels were significantly higher in the NPDR and PDR groups (114.4 SD 52.5 pg/mL and 150.8 SD 49.7 pg/mL, respectively) compared to the no DR group (40.4 SD 26.5 pg/mL, p < 0.001). There was no significant difference in the mean serum VEGF levels between the three groups. There was a fair correlation between serum and tear VEGF levels (p = 0.015, r = 0.263). Conclusion VEGF levels in tears were significantly higher amongst diabetic patients with DR compared to those without DR and were significantly associated with the severity of DR. There was a fair correlation between serum and tear VEGF levels. Detection of VEGF in tears is a good non-invasive predictor test for the severity of DR. A large cohort study is needed for further evaluation.

Abstract
BACKGROUND AND OBJECTIVE Preeclampsia(PE) is adisordercharacterized byhypertensionandproteinuria. There is accumulating evidence that this is a disease of the endothelium. Angiogenic factors may be responsible for the regulation of placental vascular development. Clinicians cannot predict pre-eclampsia prior to the onset symptoms. An ideal bio-marker for pre-eclampsia prediction is during the first trimester. This study investigated the serum levels of tumor necrosis factor-α (TNF-α), C-reactive protein (CRP) and the gene expressions of vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS) and p53 in PE trying to find out potential bio-markers for prediction and diagnosis of PE. MATERIAL AND METHODS A total of 100 female volunteers were involved in this study and their ages were ranged from 25-35 years. They were divided into three groups: Group (1) was 20 healthy non-pregnant women, group (2) was 20 pregnant women normal pregnancies and group (3) was 60 preeclamptic patients. The study participants were enrolled at the Department of Obstetrics and Gynaecology at Mansoura University Hospital, Mansoura, Egypt. The study was approved by the Research Ethics Committee (Faculty of Science, Al Azhar University, Egypt) approved on the March 15, 2014) all women gave written informed consent. Serum levels of CRP, IL-10 and TNF-α were evaluated, in addition to the gene expression of VEGF, eNOS and p53. RESULTS Significant elevations in the serum levels of blood pressure, TNF-α and CRP were observed in PE patients. Additionally, the gene expression of VEGF, eNOS and P53 were down-regulated in preeclampsia. CONCLUSION Elevated serum levels of TNFα and CRP, in addition to the down-regulation of eNOS may be used as good predictors for preeclampsia. The TNF-α and VEGF gene were recommended used as markers for PE to be added to routine testes of pregnant women.

Abstract
AIMS There is a need for predictive and surrogate response biomarkers to support treatment with antiangiogenic vascular endothelial growth factor (VEGF) inhibitors. We aimed to identify a minimally-invasive biomarker predicting benefit from cediranib pretreatment or early during treatment in patients with recurrent or metastatic cervical cancer. METHODS Blood samples were collected before treatment, during treatment and upon disease progression where appropriate from patients enrolled in CIRCCa, a randomised phase II trial of carboplatin and paclitaxel with or without cediranib. Plasma concentrations of VEGF-A, VEGF-receptor 2, Ang1 and Tie2 were measured using multiplex enzyme-linked immunosorbent assay. Pretreatment and temporal changes of the biomarkers were investigated using proportional hazard regression and unsupervised clustering analysis. RESULTS Samples (n = 556) from 52 patients were analysed. VEGF-receptor 2 (P = .0006) and Tie2 (P = .04) were downregulated following cediranib, while VEGF-A (P = .0025) was upregulated. High Eastern Cooperative Oncology Group performance status (P = .02, hazard ratio [HR] = 2.15, 95% confidence interval [CI] 1.13-4.09) and low pretreatment Tie2 concentrations (P = .003, HR = 0.57, 95%CI 0.39-0.83) were independent prognostic factors associated with reduced progression-free survival. Two patterns of changes in VEGF-A following cediranib were identified. Patients with elevated VEGF-A in the first 3 treatment cycles, regardless of magnitude, had reduced progression-free survival in the placebo arm but improved survival with the addition of cediranib (P = .019, HR = 0.13, 95% CI 0.02-0.71). CONCLUSION Patterns of early elevation in plasma VEGF-A should be studied further as a potential biomarker to predict treatment benefit from cediranib.

Abstract
BACKGROUND Behçet's disease is a multisystemic vasculitis, associated with vascular endothelial dysfunction. Currently, the prognosis is unpredictable, because there is still no valid laboratory marker indicating the disease activity in Behçet's disease. Endothelial progenitor cells and circulating endothelial cells are newly introduced hematological markers which are presumed to take part in the pathogenesis of vasculitis. OBJECTIVES To evaluate the levels of endothelial progenitor cells and subtypes and circulating endothelial cells in patients with Behçet's disease and to describe their relationship with the disease activity. METHODS A total of 45 patients with Behçet's disease and 28 healthy controls were included in the study. Endothelial progenitor cells (CD34+CD133+KDR+ as early endothelial progenitor cells and CD34+KDR+ as late endothelial progenitor cells), and circulating endothelial cells (CD34+CD133+) were measured by flow cytometry. RESULTS The mean plasma level of endothelial progenitor cells and circulating endothelial cells, vascular endothelial growth factor, matrix metalloproteinase-9, C-reactive protein, and erythrocyte sedimentation rate were significantly higher in patients with Behçet's disease. All of these parameters except circulating endothelial cells were also found to be higher in patients with active disease than in patients with inactive disease. Early endothelial progenitor cells showed significant correlations with C-reactive protein and circulating endothelial cells. STUDY LIMITATIONS The cross-sectional nature of the study and patient characteristics such as being under treatment, which can affect endothelial progenitor cells numbers. CONCLUSION The increase in endothelial progenitor cells may play an essential role in the repair of endothelial injury in Behçet's disease, especially in the active period of the disease. Thus, endothelial progenitor cells can indicate the disease activity. In addition, endothelial progenitor cells and circulating endothelial cells can be used as endothelial repair and injury markers for Behçet's disease, respectively.

Abstract
PURPOSE OF REVIEW This review provides a comprehensive insight into the angiogenic profile of hypertensive and normotensive pregnancies compromised by HIV infection. Furthermore, we evaluate the economic implementation of the sFlt-1/PlGF ratio and review the reports on therapeutic apheresis in limiting sFlt-1 production. RECENT FINDINGS In preeclampsia, an increased expression of sFlt-1 triggers angiogenic imbalance. Women of African ancestry have high levels of angiogenic factors than other racial groups. The sFlt-1/PlGF ratio shows promise in the early assessment of preeclampsia, while sFlt-1 apheresis restores angiogenic imbalance. Studies suggest antiretroviral therapy does not impact the angiogenic shift in preeclampsia development. The angiogenic profile in pregnant women of different races influences preeclampsia development. Despite the opposing immune response in HIV infection and preeclampsia, the HIV tat protein strongly mimics vascular endothelial growth factor (VEGF); hence, it is plausible to assume that HIV infection may ameliorate the angiogenic imbalance in preeclampsia.

Abstract
Bronchial asthma (BA) remains the most common chronic respiratory disease in children and is characterized by reversible airway obstruction and airway hyperresponsiveness. MicroRNAs (miRNAs) are a class of small, highly conserved non-coding RNA molecules that regulate gene expression at the posttranscriptional level. MiRNAs can either augment or minimize the allergic inflammation in asthma. It has been noted that a group of miRNAs may affect the development of asthma and related inflammatory response. The vascular endothelial growth factor (VEGF) is produced by different types of cells and has a major role in both, physiological and pathological angiogenesis. Our aim was to study serum expression of three microRNAs; 221, 222,15a and Vascular Endothelial Growth Factor A (VEGF-A) levels in children with bronchial asthma. The study included 30 children with BA and a control group of 20 apparently healthy, age and sex matched, children. Quantitative reverse transcription (q RT) polymerase chain reaction (PCR) was performed to examine the expression levels of miR-221, 222 and 15a in patients' sera. Levels of serum VEGF-A were quantified utilizing an ELISA technique. Serum levels of both miRNA-221 and miRNA-222 were not significantly different between pediatric asthmatic patients versus controls (P=0.76 and 0.52, respectively), but showed increase with the disease severity (persistent versus intermittent) (P= 0.09, 0.07, respectively). Serum miRNA-15a expression was significantly down-regulated in asthmatic patients versus the control group (P=0.03). miRNA-15a expression did not differ among various grades of BA (P=0.33) and was not correlated with serum levels of VEGF-A (P=0.56). The level of VEGF-A was significantly increased in serum of pediatrics with bronchial asthma in comparison to the control group (P=0.026). In conclusion, miRNA-15a and VEGF-A may have a role in BA pathogenesis, while miRNA-221 and 222 may reflect BA disease severity.

Abstract
BACKGROUND Prognosis of peripheral artery disease (PAD), especially critical limb ischemia (CLI), is very poor despite the development of endovascular therapy and bypass surgery. Many patients result in having leg amputation. We decided to investigate the safety and efficacy of plasmid of internal ribosome entry site/vascular endothelial growth factor (VEGF) 165/hepatocyte growth factor (HGF) gene therapy (GT) in patients suffered from CLI. METHODS Administration of plasmid of internal ribosome entry site/VEGF165/HGF was performed in 12 limbs of 12 patients with rest pain and ischemic ulcers due to CLI. Plasmid was injected into the muscles of the ischemic limbs. The levels of VEGF in serum and the ankle-brachial index (ABI) were measured before and after treatment. RESULTS Mean (±SD) plasma levels of VEGF increased nonsignificantly from 258 ± 81 pg/L to 489 ± 96 pg/L (P > 0.05) 2 weeks after therapy, and the ABI improved significantly from 0.27 ± 0.20 to 0.50 ± 0.22 (P < 0.001) 3 months after therapy. Ischemic ulcers healed in 9 limbs. Amputation was performed in 3 patients because of advanced necrosis and wound infection. However, the level of amputations was lowered below knee in these cases. Complications were limited to transient leg edema in 3 patients and fever in 2 patients. CONCLUSIONS Intramuscular administration of plasmid of internal ribosome entry site/VEGF165/HGF is safe, feasible, and effective for patients with critical leg ischemia.
