Diabetic cardiomyopathy is a specific disease process distinct from coronary artery disease and hypertension. The disease features cardiac remodeling stimulated by hyperglycemia of the left ventricle wall and disrupts contractile functions. Cardiac mast cells may be activated by metabolic byproducts resulted from hyperglycermia and then participate in the remodeling process by releasing a multitude of cytokines and bioactive enzymes. Nedocromil, a pharmacologic stabilizer of mast cells, has been shown to normalize cytokine levels and attenuate cardiac remodeling. In this study, we describe the activation of cardiac mast cells by inducing diabetes in normal mice using streptozotocin (STZ). Next, we treated the diabetic mice with nedocromil for 12 weeks and then examined their hearts for signs of cardiac remodeling and quantified contractile function. We observed significantly impaired heart function in diabetic mice, as well as increased cardiac mast cell density and elevated mast cell secretions that correlated with gene expression and aberrant cytokine levels associated with cardiac remodeling. Nedocromil treatment halted contractile dysfunction in diabetic mice and reduced cardiac mast cell density, which correlated with reduced bioactive enzyme secretions, reduced expression of extracellular matrix remodeling factors and collagen synthesis, and normalized cytokine levels. However, the results showed nedocromil treatments did not return diabetic mice to a normal state. We concluded that manipulation of cardiac mast cell function is sufficient to attenuate cardiomyopathy stimulated by diabetes, but other cellular pathways also contribute to the disease process. © 2013 Huang et al.

Background: Major depressive disorder (MDD) is an independent risk factor for coronary heart disease (CHD), and influences the occurrence and prognosis of cardiovascular events. Although there is evidence that antidepressants may be cardioprotective after acute myocardial infarction (AMI) comorbid with MDD, the operative pathophysiological mechanisms remain unclear. Our aim was therefore to explore the molecular mechanisms of escitalopram on myocardial apoptosis and the expression of Bax and Bcl-2 in a rat model of depression during myocardial ischemia/reperfusion (I/R). Methods: Rats were divided randomly into 3 groups (n = 8): D group (depression), DI/R group (depression with myocardial I/R) and escitalopram + DI/R group. The rats in all three groups underwent the same chronic mild stress and separation for 21 days, at the same time, in the escitalopram + DI/R group, rats were administered escitalopram by gavage (10 mg/kg/day). Ligation of the rat's left anterior descending branch was done in the myocardial I/R model. Following which behavioral tests were done. The size of the myocardial infarction was detected using 1.5% TTC dye. The Tunel method was used to detect apoptotic myocardial cells, and both the Rt-PCR method and immunohistochemical techniques were used to detect the expression of Bcl-2 and Bax. Results: Compared with the D and DI/R groups, rats in Escitalopram + DI/R group showed significantly increased movements and sucrose consumption (P < .01). Compared with the DI/R group, the myocardial infarct size in the escitalopram + DI/R group was significantly decreased (P < .01). Compared with the D group, there were significantly increased apoptotic myocardial cells in the DI/R and escitalopram + DI/R groups (P < .01); however compared with the DI/R group, apoptotic myocardial cell numbers in the escitalopram + DI/R group were significantly decreased (P < .01). Compared with the DI/R group, there was a down-regulated Bax:Bcl-2 ratio in the escitalopram + DI/R group (P < .01). Conclusions: These results suggest that in patients with AMI comorbid with MDD, there is an increase in pro-apoptotic pathways that is reversed by escitalopram. This suggests that clinically escitalopram may have a direct cardioprotective after acute myocardial infarction. © Wang et al.

Background: Colorectal cancer (CRC) remains a major worldwide cause of cancer-related morbidity and mortality largely due to the insidious onset of the disease. The current clinical procedures utilized for disease diagnosis are invasive, unpleasant, and inconvenient. Hence, the need for simple blood tests that could be used for the early detection is crucial for its ultimate control and prevention.Methods: The present work is a case-control study focused on proteomic analysis of serum of healthy volunteers and CRC patients by the ClinProt profiling technology based on mass spectrometry. This approach allowed to identifying a pattern of proteins/peptides able to differentiate the studied populations. Moreover, some of peptides differentially expressed in the serum of patients as compared to healthy volunteers were identified by LTQ Orbitrap XL.Results: A Quick Classifier Algorithm was used to construct the peptidome patterns (m/z 1208, 1467, 1505, 1618, 1656 and 4215) for the identification of CRC from healthy volunteers with accuracy close to 100% (>CEA, P < 0.05). Peaks at m/z 1505 and 1618 were identified as alpha-2-HS-glycoprotein precursor and tubulin beta chain, respectively.Conclusions: Alpha-2-HS-glycoprotein precursor and tubulin beta chain could be involved in the pathogenesis of CRC and perform as potential serology diagnosis biomarker. © 2014 Fan et al.; licensee BioMed Central Ltd.

Laparoscopic radial nephrectomy (LRN) and microwave ablation (MWA) are optional treatment for renal cell carcinoma (RCC). However, the comparative study with two techniques remains lacking. The aim of this study was to evaluate midterm results of MWA vs. LRN in patients with small RCC. A total of 426 patients with ≤4 cm RCC were included from April 2006 to October 2012. Ninety-eight patients underwent MWA and 328 patients LRN. The survival, recurrence, and renal function changes were compared between two treatments. Although overall survival after MWA (82.6% at 5 years) was lower than those after LRN (98.6% at 5 years, p = 0.0004), the RCC-related survival (97% at 5 years) was comparable to those following LRN (98% at 5 years, p = 0.38). One local tumor progress occurred at 32 months after MWA and none after LRN. The major complication rates were comparable between two techniques (1.7% in MWA vs. 1.5% in LRN, p = 0.75), but MWA showed less renal function damage than LRN (p < 0.0001). The multivariate analysis showed the presence of postablation extrarenal metastasis may become a predictor of the oncologic outcome (p = 0.059) and treatment modality had no influence (p = 0.965). This study demonstrates that MWA and LRN provide comparable results in small RCC outcomes. © 2015, Springer Science+Business Media New York.

Objective: This study aims to investigate the characteristics of liver X receptor α (LXRα) and its target gene expression, as well as cholesterol efflux in human macrophages treated by nicotine. Methods: Human monocyte-derived macrophages were collected. Before apoA-I-mediated human monocyte-derived macrophage cholesterol efflux, and mRNA expression of LXRα, and some of its target genes being detected, the macrophages were induced with or without nicotine. Results: Pre-incubation of Human monocyte-derived macrophages with nicotine, cholesterol efflux was suppressed to apolipoprotein AI. Nicotine also inhibited LXRαand some of its target genes mRNA expression involved cholesterol metabolism, and facilitated some inflammatory genes expression. Conclusion: The changed function of cholesterol efflux and some genes expression may be the pathogenetic cause, and LXR activity of macrophage may offer potential therapeutic benefit in the treatment of atherosclerosis. Thus nicotine can regulate foam cell formation by inhibiting LXR pathway. © 2015, E-Century Publishing Corporation. All rights reserved.

Pneumonia is the most common cause of mortality in stroke patients and it has been demonstrated to contribute to mortality and poor functional outcome following stroke in the majority of clinical studies. The risk of infection may be attributed to stroke-induced immunodepression syndrome (SIDS). Cytokine production is increased in SIDS. However, the correlation between biomarkers and the risk of post-stroke pneumonia in patients with diabetes mellitus is not clear. The aim of this study was to determine the correlation between pneumonia and the levels of C-reactive protein (CRP) and interleukin-6 (IL-6), as well as to identify early predictors of pneumonia in acute ischemic stroke patients with diabetes mellitus. Additionally, we investigated the impact of pneumonia on functional outcome after 1 month. A total of 106 ischemic stroke patients with diabetes mellitus who were admitted after the onset of symptoms were included in the study. They were divided into two groups, the pneumonia and non-pneumonia groups. CRP, IL-6, white blood cells (WBCs), mean body temperature and National Institutes of Health Stroke Scale (NIHSS) score were measured at the time of admission. The modified Rankin Scale score was assessed at 30 days. The levels of IL-6, CRP and WBCs, as well as mean body temperature were significantly higher in the patients with pneumonia than in the patients without pneumonia. There were also significant differences between the pneumonia and non-pneumonia groups in age, admission NIHSS score, length of hospital stay and dysphagia. Pneumonia patients had worse outcomes compared with patients without pneumonia at 1 month. Age, NIHSS score and dysphagia were significantly associated with pneumonia. WBCs and mean body temperature were not significant predictors of pneumonia. Older patients with more severe ischemic stroke are more susceptible to the development of pneumonia during the stay in hospital. Pneumonia contributes to poor functional outcome. IL-6, CRP, age, NIHSS score and dysphagia may predict the occurrence of pneumonia on the day of stroke symptom onset.

Found in inflammatory zone (FIZZ1), also known as hypoxia-induced mitogenic factor (HIMF), is a secreted protein formed by 111 amino acid residues. FIZZ1 is mainly located in alveolar epithelial cells, white adipose tis-sue and the heart. This study aimed to explore the effects of FIZZ1 on the angiogenic ability of cultured rat aortic endothelial cells (RAECs) and the potential mechanism. The RAECs were cultured in the extracellular matrix (ECM) supplemented with 10% fetal bovine serum (FBS). Matrigel assay was used to detect the angiogenic ability of the RAECs and Agilent Rat Microarray containing 41,000 genes/ESTs was used to screen the differentially expressed genes of the RAECs after they were treated with FIZZ1 (5 × 10-9~2 × 10-8 mol/L). The results were verified using RT-PCR method. We found that FIZZ1 markedly enhanced the angiogenic ability of RAECs (22.6 ± 2.94 vs. 19.7 ± 2.57, P < 0.01; 28.5 ± 3.32 vs. 19.7 ± 2.57, P < 0.01; 36.9 ± 5.01 vs. 19.7 ± 2.57, P < 0.01) in a dose-dependent manner (5 × 10-9~2 × 10-8 mol/L). 440 genes (Gng8, Atg9a, Gdf6, etc.) were found to be up-regulated and 497 genes (Hbb-b1, Camk1g, etc.) down-regulated in the experimental group. Changes in Gng8 and Atg9a were revealed by RT-PCR. FIZZ1 could enhance angiogenesis of RAECs by up-regulating Gng8 and Atg9a.

Objective: This study aims to observe the risk factors of cardiovascular disease in patients after kidney transplantation. Methods: Total 102 patients after renal transplantation (group A) and 96 clinic examination cases (group B) were recruited. Blood pressure, blood urea nitrogen (BUN) and creatinine (Cr), blood glucose (GLU), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and apolipoprotein A-I (apoA-I) of the subjects were tested. These indexes were tested 3 times in group A in the 1, 2, and 3 month after kidney transplantation surgery. Electrocardiogram examination was done in the third month after kidney transplantation surgery. Results: There were significant differences in the incidence of hypertension, hyperglycemia and dyslipidemia between the two groups. After operation, the levels of BUN and Cr decreased significantly in 57 cases of group A without taking antihypertensive drugs (P<0.01). However, there was no significant difference in the blood pressure regardless of the systolic blood pressure (SBP) and diastolic blood pressure (DBP) before and after operation. In group A, the abnormal rate of ECG was 65%, the incidence of ST-T changes, prolongation of QT interval, left ventricular hypertrophy and left ventricular high voltage increased significantly (P<0.01). Conclusion: The incidence of coronary heart disease risk factors such as hypertension and hyperglycemia are high in patients after renal transplantation. © 2014 Professional Medical Publications.

While there is evidence that the development and course of major depressive disorder (MDD) symptomatology is associated with vascular disease, and that there are changes in energy utilization in the disorder, the extent to which cerebral blood flow is changed in this condition is not clear. This study utilized a novel imaging technique previously used in coronary and stroke patients, 320-slice Computed-Tomography (CT), to assess regional cerebral blood flow (rCBF) in those with MDD and examine the pattern of regional cerebral perfusion. Thirty nine participants with depressive symptoms (Hamilton Depression Rating Scale 24 (HAMD24) score > 20, and Self-Rating Depression Scale (SDS) score > 53) and 41 healthy volunteers were studied. For all subjects, 3 ml of venous blood was collected to assess hematological parameters. Transcranial Doppler (TCD) ultrasound was utilized to measure parameters of cerebral artery rCBFV and analyse the Pulsatility Index (PI). 16 subjects (8 = MDD; 8 = healthy) also had rCBF measured in different cerebral artery regions using 320-slice CT. Differences among groups were analyzed using ANOVA and Pearsons tests were employed in our statistical analyses. Compared with the control group, whole blood viscosity (including high\middle\low shear rate)and hematocrit (HCT) were significantly increased in the MDD group. PI values in different cerebral artery regions and parameters of rCBFV in the cerebral arteries were decreased in depressive participants, and there was a positive relationship between rCBFV and the corresponding vascular rCBF in both gray and white matter. rCBF of the left gray matter was lower than that of the right in MDD. Major depression is characterized by a wide range of CBF impairments and prominent changes in gray matter blood flow. 320-slice CT appears to be a valid and promising tool for measuring rCBF, and could thus be employed in psychiatric settings for biomarker and treatment response purposes.
