Abstract
To assess the potential effects of Cytotoxic T-lymphocyte antigen 4 (CTLA4) gene polymorphisms on susceptibility to gastric cardia adenocarcinoma (GCA), we genotyped four polymorphisms (rs733618 A>G, rs16840252 C>T, rs231775 G>A and rs3087243 G>A) in CTLA4 and calculated odds ratios (ORs) with the corresponding 95% confidence intervals (95% CIs) for the genotype and allele distributions between GCA cases and controls. The CTLA4 genotypes were determined by the polymerase chain reaction-ligase detection reaction (PCR-LDR) analysis in 330 GCA patients and 608 unrelated cancer-free controls. In this case-control study, there was no significant difference in the genotype and allele distributions of four CTLA4 polymorphisms between GCA patients and controls. However, haplotype association analysis indicated that compared with CTLA4 Grs733618 Crs16840252 Grs231775 Crs3087243 , CTLA4 Grs733618 Crs16840252 Ars231775 Grs3087243 and Ars733618 Crs16840252 Grs231775 Ars3087243 haplotypes conferred increased risks of GCA (OR = 6.46, 95% CI = 1.33-31.28; P = 0.012; both); however, CTLA4 Ars733618 Crs16840252 Ars231775 Grs3087243 and Ars733618 Trs16840252 Grs231775 Grs3087243 haplotypes conferred decreased risks of GCA (P = 0.001 and P = 0.011, respectively). These results highlight that the rare CTLA4 haplotypes may affect the development of GCA in the Chinese population.

Abstract
OBJECTIVE To investigate the value of brain magnetic resonance imaging (MRI) in evaluating the intracranial injuries in patients with juvenile onset systemic lupus erythematosus (SLE). METHOD Data of brain MRI, CT, electroencephalogram (EEG), cerebrospinal fluids analysis and clinical features of the central nervous system of 44 patients from March 2007 to March 2015 with juvenile onset SLE who were not treated with glucocorticoids (Gcs) and immunosuppressive agents (Is) were retrospectively analyzed and compared. RESULT Twenty-seven out of 44 patients demonstrated abnormal signs on brain MRI, including encephalatrophy, cerebral infarction, demyelination, encephalorrhagia, vertebral arteriostenosis and abnormal signals on the brain diffusion-weighted imaging (DWI). Sixteen patients had clinical features of the central nervous system involvement, fifteen had continuous headache, nine had continuous dizziness, seven had convulsions, three had hemiplegia, one had blurred vision. Physical examination of the nervous system: ten patients had abnormal signs, all had cervical rigidity, five showed pyramidal sign, three showed loss of muscle tone, two with cranial neuropathies and one had paresthesia. EEG: Ten patients showed abnormal waves on EEG, all showed diffused slow-waves, and five showed sharp waves and spikes. Cerebrospinal fluids analysis: six patients had abnormal results, five of them had cell count elevation and one had cell count and protein elevation, while there was glucose and chloride degression. Brain CT: Eight patients received CT scan, two showed cerebral infarction. χ(2) test was used to compare the differences among head MRI, EEG, cerebrospinal fluid analysis, physical examination of the nervous system, clinical features of the nervous system, the difference was significant(χ(2)=12.055, P=0.001; χ(2)=19.627, P=0.001; χ(2)=3.859, P=0.049; χ(2)=12.055, P=0.001). CONCLUSION Brain MRI may be a better method in early diagnosis of intracranial injuries than CT, EEG, cerebrospinal fluid analysis and physical examination of the nervous system. Patients with juvenile onset SLE should receive brain MRI after diagnosis in order to investigate the intracranial injuries. Abnormal signals on the DWI are the signs of active disease.

Abstract
The production performance, efficacy, and safety of two types of vaccines for infectious bursal disease virus (IBDV) were compared with in-ovo vaccination of Cobb 500 broiler chickens for gross and microscopic examination of the bursa of Fabricius, bursa/body weight (b/B) ratio, flow cytometry, and serologic response to Newcastle disease virus (NDV) vaccination. One vaccine was a recombinant HVT-IBD vector vaccine (HVT as for herpesvirus of turkeys) and the other was an intermediate plus live IBDV vaccine. A significant difference was detected at 21 d. Eight of 10 chickens that received the IBDV live vaccine had severe bursal lesions and a relatively low b/B ratio of 0.95, and an inhibited NDV vaccine response. On the other hand, the HVT-IBD vector vaccine resulted in mild bursal lesions and a b/B ratio of 1.89. Therefore, the live vaccine had lower safety than that of the HVT-IBD vector vaccine. To determine the protective efficacy, chickens were intraocularly challenged at 24 d. Eight of 10 chickens in the IBDV live vaccination group showed gross and histological lesions characterized by hemorrhage, cyst formation, lymphocytic depletion, and a decreased b/B ratio. In contrast, the HVT-IBD vector vaccinated chickens showed mild gross and histological lesions in three of 10 chickens with a b/B ratio of 1.36, which was similar to that of the unchallenged controls. Vaccinated chickens showed a significant increase in IBDV antibody titers, regardless of the type of vaccine used. In addition, significantly better broiler flock performance was observed with the HVT-IBD vector vaccine compared to that of the live vaccine. Our results revealed that the HVT-IBD vector vaccine could be used as an alternative vaccine to increase efficacy, and to have an improved safety profile compared with the IBDV live vaccine using in-ovo vaccination against the Korean very virulent IBDV in commercial broiler chickens.

Abstract
BACKGROUND AND PURPOSE Stent-assisted coiling of intracranial aneurysms requires antiplatelet therapy, typically aspirin and clopidogrel to prevent thromboembolic complications. There is a substantial concern that tirofiban may increase the risk of hemorrhage when used as an antiplatelet premedication in ruptured intracranial aneurysms. Our aim was to evaluate the safety and efficacy of intravenous tirofiban administration, instead of oral dual antiplatelet agents, as an antiplatelet premedication for stent-assisted coiling in patients with acutely ruptured intracranial aneurysms. MATERIALS AND METHODS We conducted a retrospective review of a data base containing a consecutive series of patients who underwent stent-assisted coiling for acutely ruptured intracranial aneurysms between March 2010 and January 2015. Intravenous tirofiban was administered to all patients before stent-assisted coiling, instead of premedication with loading doses of aspirin or clopidogrel. RESULTS Forty patients with 41 aneurysms received intravenous tirofiban and underwent stent-assisted coiling. None of the patients had a newly developed intracerebral hemorrhage, subarachnoid hemorrhage, or intraventricular hemorrhage. Intraprocedural aneurysmal rupture occurred in 2 patients (5%). Cerebral infarction developed in 2 patients (5%). Ventriculostomy-related hemorrhage was seen in 2 of 10 patients in whom ventriculostomy was performed before or after coiling. Thirty-four (85%) patients had a good outcome (Glasgow Outcome Score of 4 or 5) at the time of discharge, but 1 patient died of cardiac arrest. None of the patients developed thrombocytopenia, retroperitoneal, gastrointestinal, or genitourinary bleeding related to tirofiban administration. CONCLUSIONS In our study, tirofiban showed a low risk of symptomatic hemorrhagic or thromboembolic complications. Tirofiban may offer a safe and effective alternative as an antiplatelet premedication during stent-assisted coiling of acutely ruptured intracranial aneurysms.

Abstract
Intervertebral disc degeneration is the main cause of lumbago disease, in which the extracellular matrix structure and moisture in the nucleus pulposus is lost continuously. In this study, we aimed to detect differential expression of silence mating type information regulation 2 homolog 1 (SIRT1) and matrix metalloproteinase-1 (MMP-1) in human intervertebral disc nucleus pulposus cells and to explore the effects of SIRT1 and MMP-1 on the development of the intervertebral disc degeneration. Intervertebral disc nucleus pulposus specimens from 41 patients who underwent lumbar protrusion resection at HuiZhou Municipal Central Hospital, during the period from October 2011 to December 2013, were studied in comparison with 23 control cases from patients who underwent fractured lumbar resection. In degenerated human intervertebral disc nucleus pulposus cells, the expression of SIRT1 is decreased and MMP-1 is increased compared with that of the control cells. Resveratrol could reverse these effects, thereby increasing the expression of SIRT1 (0.87 ± 0.07 vs 0.54 ± 0.04), Coll2α1 (0.90 ± 0.08 vs 0.38 ± 0.01), and aggrecan (0.69 ± 0.07 vs 0.42 ± 0.05) and decreasing the expression of MMP-1 (0.61 ± 0.03 vs 0.93 ± 0.08). These results suggest that resveratrol could possibly reverse the process of intervertebral disc degeneration and thus could be applied as a potential drug for the disease.

Abstract
BACKGROUND/OBJECTIVES The use of dietary supplements (DSs) by children and adolescents is increasing. The aim of this study was to identify the characteristics of DS users and examine the nutritional contributions of DSs to total nutrient intakes in children and adolescents, using data obtained from a national survey. SUBJECTS/METHODS In total, 3134 subjects aged 9-18 years who participated in the 4th Korea National Health and Nutrition Examination Survey (2007-2009) were selected; the survey included 24-h recall questions on food intake and questions on DS use over the past year. Nutrient intakes from DSs were calculated using the aid of a label-based database on such supplements, and individual total nutrient intakes were derived by combining information on the foods and DSs consumed by each subject. RESULTS There were 895 DS users (28.5%), 85.2% of whom (n=577) had complete DS nutrient information and were therefore defined as identified-DS users. Identified-DS users were slightly younger and had a greater household income and better nutritional knowledge than did non-users. The most frequently consumed type of supplement was a 'multivitamin and minerals' complex. For total nutrient intake, identified-DS users had a significantly higher intake of most of the nutrients, except for macronutrient and sodium than non-users. In all identified-DS users, the contribution of vitamins and minerals from DSs to total nutrient intake was higher than energy and macronutrients. CONCLUSIONS DS use by children and adolescents can improve micronutrient status, but it also increases the risk of excessive intake of certain vitamins and minerals.

Abstract
BACKGROUND AND PURPOSE Smoking is a major risk factor for cognitive decline and dementia. However, the exact pathobiology of smoking remains unknown. The effects of smoking on cortical thickness as a biomarker of neurodegeneration or white matter hyperintensities and lacunes as biomarkers of cerebrovascular burden were concurrently evaluated. METHODS Our study included 977 cognitively normal men who visited a health promotion centre and underwent medical check-ups, including 3.0 T magnetic resonance imaging. Participants were categorized into never smoker, past smoker or current smoker groups and pack-years and the years of smoking cessation were used as continuous variables. RESULTS The current smoker group exhibited cortical thinning in frontal and temporo-parietal regions compared with the never smoker group. These effects were particularly prominent in smokers with a high cumulative exposure to smoking in the current smoker group. However, there was no association between smoking and the severity of white matter hyperintensity or number of lacunes. CONCLUSION Our findings indicate that smoking might impact on neurodegeneration rather than cerebrovascular burdens in cognitively normal men, suggesting that smoking might be an important modifiable risk factor for the development of Alzheimer's disease.

Abstract
Objective To study whether subvolumes with a high pre-chemoradiotherapy (CRT) FDG uptake could identify residual metabolically-active volumes (MAVs) post-CRT within individual esophageal tumors. Accurate identification will allow simultaneous integrated boost to these subvolumes at higher risk to improve clinical outcomes. Methods Twenty patients with esophageal cancer were treated with CRT plus surgery and underwent FDG PET/CT scans before and after CRT. The two scans were rigidly registered. Seven MAVs pre-CRT and four MAVs post-CRT within a tumor were defined with various SUV thresholds. The similarity and proximity between the MAVs pre-CRT and post-CRT were quantified with three metrics: fraction of post-CRT MAV included in pre-CRT MAV, volume overlap and centroid distance. Results Eight patients had no residual MAV. Six patients had local residual MAV (SUV ≥2.5 post-CRT) within or adjoining the original MAV (SUV ≥2.5 pre-CRT). On average, less than 65% of any post-CRT MAVs was included in any pre-CRT MAVs, with a low volume overlap <45%, and large centroid distance >8.6 mm. In general, subvolumes with higher FDG-uptake pre-CRT or post-CRT had lower volume overlap and larger centroid distance. Six patients had new distant MAVs that were determined to be inflammation from radiation therapy. Conclusions Pre-CRT PET/CT cannot reliably identify the residual MAVs within individual esophageal tumors. Simultaneous integrated boost to subvolumes with high FDG uptake pre-CRT may not be feasible.

Abstract
Cudrania tricuspidata (Moraceae) is a deciduous tree widely distributed in East Asia, including China, Korea, and Japan. It produces delicious fruit, and its cortex and root bark have been used as a traditional medicine to treat neuritis and inflammation. As C. tricuspidata has become known as a functional food, its cultivation area and production gradually have increased in Korea. However, information of viral disease in C. tricuspidata is very limited. In September 2012, open-field-grown C. tricuspidata trees showing virus-like symptoms of mosaic, yellowing, and distortion on the leaves were found in Naju, Korea. The fruit production in the diseased trees decreased to 20 to 40% of that in healthy trees. To identify causal agent(s), total RNA was isolated from the symptomatic leaves and used to generate a transcriptome library using the TruSeq Stranded Total RNA with Ribo-Zero Plant kit (Illumina, San Diego, CA) according to the manufacturer's instruction. The transcriptome library was analyzed by next-generation sequencing (NGS) using an Illumina HiSeq2000 sequencer. NGS reads were quality filtered and de novo assembled by the Trinity pipeline, and the assembled contigs were analyzed against the viral reference genome database in Genbank by BLASTn and BLASTx searches (3). The entire NGS procedure was perofrmed by Macrogen Inc. (Seoul, South Korea). Among the analyzed contigs, one large contig (10,043 bp) was of viral origin. Nucleotide blast searches showed that the contig has a maximum identity of 89% (with 100% coverage) to the isolate MS1 (Genbank Accession No. EU761198) of Bean common mosaic virus (BCMV), which was isolated from Macroptilium atropurpureum in Australia. The presence of BCMV was confirmed by a commercially available double-antibody sandwich (DAS)-ELISA kit (Agdia, Elkhart, IN). To confirm the BCMV sequence obtained by NGS, two large fragments covering the entire BCMV genome were amplified by reverse transcription-polymerase chain reaction (RT-PCR) using two sets of specific primers (5'-AAAATAAAACAACTCATAAAGACAAC-3' and 5'-AGACTGTGTCCCAGAGCATTTC-3' to amplify the 5' half of the BCMV genome; 5'-GCATCCTGAGATTCACAGAATTC-3' and 5'-GGAACAACAAACATTGCCGTAG-3' to amplify the 3' half of the BCMV genome) and sequenced. To obtain the complete genome sequence, the 5' and 3' terminal sequences were analyzed by the 5' and 3' rapid amplification of cDNA ends (RACE) method as described previously (1). The assembled full-length sequence of BCMV isolated from C. tricuspidata was 10,051 nucleotides in length without a poly(A) tail. It was deposited in Genbank under the accession number KM076650. BCMV, a member of the genus Potyvirus, is one of the most common viruses naturally infecting legumes, including Phaseolus vulgaris (2). In general, BCMV is known to have a restricted host range outside legume species (2). Therefore, the identification of BCMV from C. tricuspidata in this report is very exceptional. Because BCMV is easily transmitted by various aphids like other potyviruses, a large-scale survey may be required for exact investigation of the BCMV incidence in C. tricuspidata to prevent rapid spread of the virus. To the best of our knowledge, this is the first report of BCMV in C. tricuspidata. References: (1) H.-R. Kwak et al. Plant Pathol. J. 29:274, 2013. (2) M. Saiz et al. Virus Res. 31:39, 1994.

Br J Cancer 2015; 112:461-7. [PMID: 25584490 PMCID: PMC4453653 DOI: 10.1038/bjc.2014.631] [Citation(s) in RCA: 51] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2014] [Revised: 11/06/2014] [Accepted: 11/30/2014] [Indexed: 12/12/2022] Open
Abstract
Background: Systemic inflammatory response (SIR) is important in the relationship between the tumour, the host, and outcome in cancer patients. However, limited data exist regarding the prognostic significance of SIR in bladder cancer. We investigate the utility of pretreatment SIR in patients with urothelial carcinoma undergoing radical cystectomy. Methods: The study cohort consisted of 419 patients with a median follow-up of 37.7 months. The SIRs used for each described prognostic nomogram are consistent with previously published data: C-reactive protein, albumin, white cell count, neutrophil count, lymphocyte count, and platelet count. Primary end point was disease-specific survival (DSS) and overall survival (OS) after surgery. Cox regression models were used to determine the time to disease-specific and overall mortality. Multivariate regression coefficients of the predictors were used to develop nomograms for predicting 5-year DSS and OS probability. Results: Multivariate Cox regression analyses revealed that albumin, lymphocyte count, and platelet count were significantly associated with a significantly increased risk for death from bladder cancer. The nomograms including each index were developed to predict the probability of 5-year DSS and OS after radical cystectomy. The C statistics were 77.8% and 77.3%, respectively, and exceeded the 2002 AJCC (72.0% and 70.3%, respectively). In the decision curve analyses, the nomograms including SIR demonstrated higher net benefit gains compared with the models without SIR. Conclusions: Cellular components of SIR have better prognostic values compared with acute-phase protein in patients undergoing radical cystectomy for bladder cancer.
