ABSTRACT
Objective: To evaluate the nutritional status by the Controlling Nutritional Status (CONUT) score and its association with the long-term prognosis in patients with acute heart failure (AHF). Methods: This prospective monocentric study consecutively enrolled patients admitted to our hospital for AHF from April 2012 to May 2016. Patients were divided into 3 groups based on the CONUT score at admission: normal (0-1), mild malnutrition (2-4) and moderate-severe malnutrition (5-12) groups. Baseline information was obtained and recorded within 24 hours after admission. All patients were followed up every 3 months by outpatient visit or telephone call until March 2019. The primary endpoint was all-cause mortality. The Kaplan-Meier survival curves and log-rank test were used to compare all-cause mortality between groups. Variables showing statistical significance in the univariate analysis were incorporated into multivariate Cox regression model to analyze the independent risk factors for all-cause mortality after discharge. Results: A total of 396 patients were enrolled in this study, including 114 patients with normal nutritional status, 200 patients with mild malnutrition and 82 patients with moderate-severe malnutrition. One hundred and fifty-eight patients died during a median follow-up of 34 (18, 46) months. The mortality was 32.4% (37/114), 39% (78/200) and 52.4% (43/82) in normal, mild malnutrition and moderate-severe malnutrition groups, respectively. The mortality was significantly higher in the moderate-severe malnutrition group than in normal nutrition group (P<0.05). However, there was no significant difference in mortality between normal and mild malnutrition group as well as between mild and moderate-severe malnutrition group (both P>0.05). Kaplan-Meier curves indicated that patients with high CONUT score group was at higher risk of all-cause mortality compared with those with low CONUT score (P=0.002). Cox proportional hazard analyses showed that the risk of all-cause mortality of moderate-severe malnutrition group was significantly higher than that of normal nutrition group (HR =1.648, 95%CI 1.021-2.660, P=0.041). Conclusions: The CONUT score of patients with AHF at admission is associated with the long-term prognosis. High CONUT score is an independent risk factor for all-cause mortality in AHF patients after discharge.

BACKGROUND@#Clinical assessment and treatment guidance for heart failure depends on a variety of biomarkers. The objective of this study was to investigate the prognostic predictive value of growth differentiation factor-15 (GDF-15) and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in assessing hospitalized patients with acute heart failure (AHF).@*METHODS@#In total, 260 patients who were admitted for AHF in the First Affiliated Hospital of Nanjing Medical University were enrolled from April 2012 to May 2016. Medical history and blood samples were collected within 24 h after the admission. The primary endpoint was the all-cause mortality within 1 year. The patients were divided into survival group and death group based on the endpoint. With established mortality risk factors and serum GDF-15 level, receiver-operator characteristic (ROC) analyses were performed. Cox regression analyses were used to further analyze the combination values of NT-proBNP and GDF-15.@*RESULTS@#Baseline GDF-15 and NT-proBNP were significantly higher amongst deceased than those in survivors (P < 0.001). In ROC analyses, area under curve (AUC) for GDF-15 to predict 1-year mortality was 0.707 (95% confidence interval [CI]: 0.648-0.762, P < 0.001), and for NT-proBNP was 0.682 (95% CI: 0.622-0.738, P < 0.001). No statistically significant difference was found between the two markers (P = 0.650). Based on the optimal cut-offs (GDF-15: 4526.0 ng/L; NT-proBNP: 1978.0 ng/L), the combination of GDF-15 and NT-proBNP increased AUC for 1-year mortality prediction (AUC = 0.743, 95% CI: 0.685-0.795, P < 0.001).@*CONCLUSIONS@#GDF-15, as a prognostic marker in patients with AHF, is not inferior to NT-proBNP. Combining the two markers could provide an early recognition of high-risk patients and improve the prediction values of AHF long-term prognosis.@*CLINICAL TRIAL REGISTRATION@#ChiCTR-ONC-12001944, http://www.chictr.org.cn.

ABSTRACT
Duodenal adenocarcinoma, especially duodenal bulb with neuroendocrine features (NEF), is extremely rare. Here, we report one such case of duodenal bulb adenocarcinoma with neuroendocrine features. A 63-year-old Han Chinese woman was admitted to our department with the diagnosis of a duodenal bulb polyp and underwent an endoscopic mucosal resection. The pathological findings confirmed it as duodenal bulb adenocarcinoma with NEF. The patient remains curative after one and half a years of follow-up. Duodenal adenocarcinoma with NEF might be a low malignant neuroendocrine tumor rather than a conventional adenocarcinoma. Endoscopic treatment, including endoscopic mucosal resection, might be an ideal option for the adenocarcinomas with NEF.

<p><b>BACKGROUND</b>Reactive oxygen species are thought to contribute to the development of renal damage. The P22phox subunit of nicotinamide adenine dinucleotide phosphate (NAPDH) oxidase, encoded by the cytochrome b245a polypeptide gene, CYBA, plays a key role in superoxide anion production. We investigated the association of CYBA rs7195830 polymorphism with estimated glomerular filtration rate (eGFR) and the role it plays in the pathogenesis of chronic kidney disease (CKD) in a Han Chinese sample.</p><p><b>METHODS</b>The Gaoyou study enrolled 4473 participants. Serum levels of creatinine were measured and eGFR was estimated using the Chronic Kidney Disease Epidemiology Collaboration equations. The CYBA polymorphisms were genotyped. Then we investigated the association between eGFR and the rs7195830 polymorphism in the recessive model.</p><p><b>RESULTS</b>The AA genotype of rs7195830 was associated with significantly lower values of eGFR compared with the GG and AG genotypes ((102.76 ± 17.07) ml×min(-1)×1.73 m(-2) vs. (105.08 ± 16.30) ml×min(-1)± 1.73 m(-2)). The association remained significant in the recessive model after adjusting for age, gender, body mass index, smoking, hypertension, diabetes mellitus, uric acid, triglyceride, low density lipoprotein cholesterol and high density lipoprotein cholesterol (β=1.666, P=0.031). The rs7195832 AA genotype was an independent risk factor for CKD: eGFR <60 ml×min(-1)×1.73 m(-2) (odds ratio=3.32; 95% CI=1.21-9.13).</p><p><b>CONCLUSION</b>The AA genotype of rs7195830 is independently associated with lower estimated glomerular filtration rate and is significantly associated with CKD.</p>

<p><b>BACKGROUND</b>Stem cell transplantation has been shown to have beneficial effects on dilated cardiomyopathy. However, mechanism for stem cell homing to cardiac tissue in dilated cardiomyopathy has not yet been elucidated.</p><p><b>METHODS</b>Mesenchymal stem cells were obtained from rat bone marrow, expanded in vitro, and labeled with (99m)Tc. Cardiomyopathy model was induced by doxorubicin in rats. (99m)Tc labeled cells were infused into the left ventricles in cardiomyopathy and control rats. Sixteen hours after injection, animals were sacrificed and different tissues were harvested to measure specific radioactivity. By use of real-time polymerase chain reaction and immunohistochemistry, mRNA and protein expressions for stromal-cell-derived factor 1 in cardiac tissue were measured.</p><p><b>RESULTS</b>Labeling efficiency of mesenchymal stem cells was (70.0 ± 11.2)%. Sixteen hours after mesenchymal stem cell transplantation, the heart-to-muscle radioactivity ratio was increased significantly in cardiomyopathy hearts as compared to control hearts. Both mRNA and protein expressions of stromal-cell-derived factor 1 were up-regulated in cardiomyopathy hearts as compared with control hearts.</p><p><b>CONCLUSION</b>In dilated cardiomyopathy induced by doxorubicin up-regulated expression of stromal-cell-derived factor 1 in heart may induce mesenchymal stem cells home to the heart.</p>

<p><b>OBJECTIVE</b>To investigate the relationship between c-reactive protein (CRP) and blood pressure in a general population.</p><p><b>METHODS</b>We randomly selected 3889 subjects aged 18 - 74 years stratified by gender and age in Baqiao, a rural area of Jiangsu Province. A standardized questionnaire was used to collect information on medical history, smoking, alcohol intake and use of medications. Blood pressure was measured by mercury sphygmomanometer. Serum CRP (hCRP) concentration was measured using a high sensitivity BNprosec immunonephelometric assay. Subjects were divided into 4 groups according to their interquartile range of CRP levers: group Q1 (men hCRP < 2.04 mg/L; women hCRP < 1.80 mg/L); group Q2 (men 2.04 mg/L ≤ hCRP < 3.01 mg/L; women 1.80 mg/L ≤ hCRP < 2.76 mg/L); group Q3 (men 3.01 mg/L ≤ hCRP < 4.14 mg/L; women 2.76 mg/L ≤ hCRP < 3.84 mg/L); and group Q4 (men 4.14 mg/L ≤ hCRP; women 3.84 mg/L ≤ hCRP).</p><p><b>RESULTS</b>Systolic blood pressure (SBP, adjusted P = 0.016) and pulse pressure (PP, adjusted P = 0.003) of men and PP (adjusted P = 0.002) of women were increased in proportion to increased CRP levels. Diastolic blood pressure was not associated with CRP levels. Multiple stepwise regression analysis showed that logCRP was independently associated with SBP and PP in men and PP in women. hCRP was independently associated with hypertension in men. Compared with group Q1, male people in group Q4 faced a 40.4% (95% confidence interval: 4.9% - 87.9%) higher risk of hypertension.</p><p><b>CONCLUSIONS</b>hCRP was independently associated with PP in men and women, and SBP in men. hCRP was independently associated with hypertension in men but not in women in this study population.</p>

<p><b>BACKGROUND</b>Evidence showed that both myocardium and blood vessels were damaged in dilated cardiomyopathy (DCM). However, the changes in arterial compliance, serum cytokines and circulating endothelial progenitor cells (EPC), and their correlations remain unknown.</p><p><b>METHODS</b>Sixty-five DCM patients and 49 healthy volunteers were studied. Both large artery compliance (C(1)) and small artery compliance (C(2)) were measured with the CVProfilor DO-2020. Quantitative enzyme-linked immunosorbent assays (ELISAs) were used to measure the levels of vascular endothelial growth factor-A (VEGF-A) and VEGF receptor 2 (VEGF-R(2)). Circulating EPC was assessed by EPC colony-forming assays and flow cytometry (CD133(+)/CD34(+) cells). Phagocytized DiI-acLDL and binded FITC-UEA-I were used to analyze endothelial lineage marker expression by immunofluorescence.</p><p><b>RESULTS</b>Although C(2) was markedly lower in DCM patients than in control group ((3.8+/-1.8) ml/mmHg x 100 vs (5.0+/-2.2) ml/mmHg x 100, P<0.0001), there was no statistically significant difference in C(1) between the two groups (P>0.05). Levels of VEGF-A, the numbers of colony-forming units (CFU) and the fractions of EPC were obviously higher in DCM patients than in control group ((127.6+/-139.5) pg/ml vs (58.8+/-42.9) pg/ml, P<0.0001; (2.5+/-1.5)% vs (0.5+/-0.3)%, P < 0.05; 23.5+/-12.8 vs 10.8+/-7.4, P<0.01, respectively) and however, there was no significant difference in VEGF-R(2) between two groups (P>0.05). LgVEGF-A was positively correlated with the number of EPC-CFU (r=0.435; P<0.05) and inversely correlated with C(2) (r= -0.543; P<0.001) in DCM patients.</p><p><b>CONCLUSIONS</b>The reduction of C(2), a sensitive marker reflecting endothelial dysfunction, was observed in DCM patients and closely related to the increase in serum VEGF-A.</p>
