Abstract
Objective: To understand the epidemiological characteristics and viral sources of dengue fever outbreak in Guangxi Zhuang Autonomous Region (Guangxi) in 2014. Methods: A combined analysis of epidemiological characteristics and genetic characteristics were performed in this study. The time, population and area distributions of the cases were analyzed. Serum samples were collected from dengue fever cases to detect NS1 antigen by using commercial ELISA kits according to the guideline of the manufacture. RT-PCR assay was conducted to detect dengue virus in NS1 positive samples. Phylogenetic tree based on E gene sequence of dengue virus were further analyzed. Results: During September-December 2014, an outbreak of dengue fever caused by dengue virus type 1 and 2 occurred in Guangxi, a total of 854 cases were reported without death, including 712 laboratory confirmed cases and 142 clinical diagnosed cases, in which 79.63% (680/854) occurred during 22 September-21 October 2014. All the cases had typical dengue fever symptoms. Most cases occurred in Nanning and Wuzhou, in which 83.61% (714/854) were in age group 15-59 years; 46.60% (398/854) were staff or people engaged in commercial service. A total 526 serum samples were tested for dengue virus serotype by RT-PCR assay. Among 414 positive samples, 345 were positive for dengue virus type 1 (DENV-1) and 69 were positive for dengue virus type 2 (DENV-2), no DENV-3 and DENV-4 were detected. The results of phylogenetic analysis of E gene sequence indicated that the sequences of 99.12%(113/114) of DENV-1 strains in Nanning in China shared 100.00% homology with the isolate (SG EHI D1/529Y13) from Singapore in 2013, which belonged to the genotype Ⅰ; All the DENV-2 isolates from Wuzhou shared 99.80% homology with the isolate (D14005) from Guangdong province, which belonged to genotype Cosmopolitan. Conclusions: The outbreak was caused by DENV-1 from Singapore and DENV-2 from Guangdong province in China. It is necessary to strengthen the surveillance and early warning for imported dengue fever, conduct vector control and improve the diagnosis of suspected dengue fever cases for the effective control of dengue fever outbreak.

Abstract
Objective:To explore the normative data of wideband acoustic absorption rate of young people with normal hearing, and the related factors of wideband acoustic immittance.Method:Eighty six cases of young people with normal hearing (43 cases of male, 43 cases of female) were collected in the clinical audiology centers of Beijing Tongren Hospital, Capital University of Medical. The average age is (22.0±1.5) years. Pure tone audiometry in the range of 250 to 8 000 Hz in each octave is carried out, and the air conduction thresholds are less than 25 dB HL; 226 Hz tympanometry were type A. For all subjects, the wideband acoustic immittance measurement was conducted at 226-8 000 Hz, and a total of 107 frequency points were carried out.Result:The test results of 172 ears were statistically analyzed.①In the range of 250-8 000 Hz,acoustic absorption rate in the low frequency range increases gradually, and the peak is found in the range of 1 000 to 3 000 Hz;getting along with the increase of frequency and acoustic absorption rate gradually decreases slowly.②The acoustic absorption rate in the range of 4 200-4 900 Hzin female subjects was significantly higher than that in male subjects.③There was no significant relationship between gender, compliance, peak pressure, and width in 226 Hz tympanometry (P=0.319, 0.831, 0.786), however there was a significant relationship between gender and the ear canal volume (P<0.01).④There was no significant relationship between gender and the resonance frequency (P>0.05).⑤There was a significant correlation between height/weight and ear canal volume (P<0.05), and there was a significant relationship between the ear canal volume and the resonance frequency (P<0.05).Conclusion:The acoustic absorption rate of young people in the low frequency range was lower, then increases gradually, and the peak was found in the range of mid-high frequency. The difference in the wideband absorption rate between genders was significant. The height and weight had influence on the results of wideband acoustic immittance.

Abstract
BACKGROUND The band 3 macrocomplex (also known as the ankyrin-associated complex) on the red cell membrane comprises two interacting subcomplexes: a band 3/glycophorin A subcomplex, and a Rh/RhAG subcomplex. Glycophorin B (GPB) is a component of the Rh/RhAG subcomplex that is also structurally associated with glycophorin A (GPA). Expression of glycophorin B-A-B hybrid GP.Mur enhances band 3 expression and is associated with lower levels of Rh-associated glycoprotein (RhAG) and Rh polypeptides. The goal of this study was to determine whether GP.Mur influenced erythroid Rh/RhAG expression at the transcript level. MATERIALS AND METHODS GP.Mur was serologically determined in healthy participants from Taitung County, Taiwan. RNA was extracted from the reticulocyte-enriched fraction of peripheral blood, followed by reverse transcription and quantitative PCR for RhAG, RhD and RhCcEe. RESULTS Quantification by real-time PCR revealed significantly fewer RhAG and RhCcEe transcripts in the reticulocytes from subjects with homozygous GYP*Mur. Independent from GYP.Mur, both RhAG and RhD transcript levels were threefold or higher than that of RhCcEe. Also, in GYP.Mur and the control samples alike, direct quantitative associations were observed between the transcript levels of RhAG and RhD, but not between that of RhAG and RhCcEe. CONCLUSION Erythroid RhD and RhCcEe were differentially expressed at the transcript levels, which could be related to their different degrees of interaction or sensitivity to RhAG. Further, the reduction or absence of glycophorin B in GYP.Mur erythroid cells affected transcript expressions of RhAG and RhCcEe. Thus, GPB and GP.Mur differentially influenced Rh/RhAG expressions prior to protein translation.

Abstract
BACKGROUND Current diagnosis and staging of pancreatic ductal adenocarcinoma (PDAC) has important limitations and better biomarkers are needed to guide initial therapy. We investigated the performance of circulating tumour cells (CTCs) as an adjunctive biomarker at the time of disease presentation. METHODS Venous blood (VB) was collected prospectively from 100 consecutive, pre-treatment patients with PDAC. Utilising the microfluidic NanoVelcro CTC chip, samples were evaluated for the presence and number of CTCs. KRAS mutation analysis was used to compare the CTCs with primary tumour tissue. CTC enumeration data was then evaluated as a diagnostic and staging biomarker in the setting of PDAC. RESULTS We found 100% concordance for KRAS mutation subtype between primary tumour and CTCs in all five patients tested. Evaluation of CTCs as a diagnostic revealed the presence of CTCs in 54/72 patients with confirmed PDAC (sensitivity=75.0%, specificity=96.4%, area under the curve (AUROC)=0.867, 95% CI=0.798-0.935, and P<0.001). Furthermore, a cut-off of ⩾3 CTCs in 4 ml VB was able to discriminate between local/regional and metastatic disease (AUROC=0.885; 95% CI=0.800-0.969; and P<0.001). CONCLUSION CTCs appear to function well as a biomarker for diagnosis and staging in PDAC.

Abstract
e15647 Background:Neutral sphingomyelinase 1 (NSMase1) catalyzes sphingomyelin to generate ceramide and mediates tumor cell apoptosis; however, the roles of NSMase1 in hepatocellular carcinoma (HCC) remain unclear. This study aims to evaluate the clinical value and prognostic significance of NSMase1 in HCC. Methods:A total of 142 patients who underwent radical hepatectomy were involved in this study. The expression of NSMase1 in HCC tissues and adjacent nontumorous liver tissues (ANLTs) was detected by quantitative real-time polymerase chain reaction and immunohistochemistry, and the association between NSMase1 expression and clinicopathologic features as well as prognosis of HCC patients was analyzed. Univariate and multivariate analyses were applied to identify independent prognostic factors. Results: NSMase1, at both mRNA and protein levels, was significantly decreased in HCC tissues compared to ANLTs. Low NSMase1 expression was associated with tumor size ( P= 0.029), TNM stage ( P= 0.040) and recurrence ( P= 0.006). Statistically, both the overall survival (OS) and disease-free survival (DFS) of low NSMase1 expression group were significantly shorter compared with high NSMase1 expression group ( p= 0.001; p= 0.001; respectively). Remarkably, the multivariate analysis showed that the low NSMase1 expression was an independent prognostic factor for OS (hazard ratio = 1.840; 95% confidence interval, 1.178-2.875, P= 0.007) and DFS (hazard ratio = 1.706; 95% confidence interval, 1.096-2.655, P= 0.018) in all enrolled HCC patients. Conclusions: NSMase1 down-regulation might actually serve as an independent prognostic factor for HCC patients. However, the roles of “NSMase1-ceramide” metabolic network in HCC deserve further studies.

Abstract
Essentials Recombinant factor VIII (FVIII) is known to be expressed at a low level in cell culture. To increase expression, we used codon-optimization of a B-domain deleted FVIII (BDD-FVIII). This resulted in 7-fold increase of the expression level in cell culture. The biochemical properties of codon-optimized BDD-FVIII were similar to the wild-type protein. SUMMARY Background Production of recombinant factor VIII (FVIII) is challenging because of its low expression. It was previously shown that codon-optimization of a B-domain-deleted FVIII (BDD-FVIII) cDNA resulted in increased protein expression. However, it is well recognized that synonymous mutations may affect the protein structure and function. Objectives To compare biochemical properties of a BDD-FVIII variants expressed from codon-optimized and wild-type cDNAs (CO and WT, respectively). Methods Each variant of the BDD-FVIII was expressed in several independent Chinese hamster ovary (CHO) cell lines, generated using a lentiviral platform. The proteins were purified by two-step affinity chromatography and analyzed in parallel by PAGE-western blot, mass spectrometry, circular dichroism, surface plasmon resonance, and chromogenic, clotting and thrombin generation assays. Results and conclusion The average yield of the CO was 7-fold higher than WT, whereas both proteins were identical in the amino acid sequences (99% coverage) and very similar in patterns of the molecular fragments (before and after thrombin cleavage), glycosylation and tyrosine sulfation, secondary structures and binding to von Willebrand factor and to a fragment of the low-density lipoprotein receptor-related protein 1. The CO preparations had on average 1.5-fold higher FVIII specific activity (activity normalized to protein mass) than WT preparations, which was attributed to better preservation of the CO structure as a result of considerably higher protein concentrations during the production. We concluded that the codon-optimization of the BDD-FVIII resulted in significant increase of its expression and did not affect the structure-function properties.

Abstract
When light emitters are being placed in close proximity to a plasmonic system, not only the emission but also the excitation can be strongly enhanced and both yield the surface plasmon polariton (SPP) mediated fluorescence enhancement. Here, we combine the rate equation model and coupled mode theory to formulate the excitation rate of light emitters located on a periodic metallic array. The rate is expressed in terms of quantities that can be measured by angle- and polarization-resolved reflectivity and photoluminescence spectroscopy. As a demonstration, we have studied the excitation rate of CdSeTe quantum dots deposited on a 2D Au nanohole array as a function of the propagation direction of the (-1,0) Bloch-like SPPs. At the excitation wavelength of 633 nm, we find the rate remains almost constant at ~44 ps-1 regardless of the propagation direction of SPPs, which move from the Γ-X towards the Γ-M direction in the first Brillouin zone, and the crossing of the (-1,0) and (0,-1) SPPs along the Γ-M direction where two bright and dark modes are formed. The results are supported by the finite-difference time-domain simulations. We conclude the excitation rate is an intrinsic parameter and the enhanced excitation of the quantum dots arises entirely from field enhancement.

Abstract
Long non-coding RNAs (lncRNAs) function in the development and progression of cancer, but only a small portion of lncRNAs have been characterized to date. A novel lncRNA transcript, 2.53 kb in length, was identified by transcriptome sequencing analysis, and was named p53-inducible cancer-associated RNA transcript 1 (PICART1). PICART1 was found to be upregulated by p53 through a p53-binding site at -1808 to -1783 bp. In breast and colorectal cancer cells and tissues, PICART1 expression was found to be decreased. Ectopic expression of PICART1 suppressed the growth, proliferation, migration, and invasion of MCF7, MDA-MB-231 and HCT116 cells whereas silencing of PICART1 stimulated cell growth and migration. In these cells, the expression of PICART1 suppressed levels of p-AKT (Thr308 and Ser473) and p-GSK3β (Ser9), and accordingly, β-catenin, cyclin D1 and c-Myc expression were decreased, while p21Waf/cip1 expression was increased. Together these data suggest that PICART1 is a novel p53-inducible tumor-suppressor lncRNA, functioning through the AKT/GSK3β/β-catenin signaling cascade.

Abstract
Objective: To explore the expression of serum interleukin-13 (IL-13) and significance of its gene polymorphism on the patients with acute exacerbation of bronchiectasis in acute exacerbation period. Methods: Forty-three patients with bronchiectasis in acute exacerbation period admitted into the respiratory ward of Fujian Provincial Hospital from December, 2014 to March, 2016 were included as bronchiectasis group. Thirty-three healthy controls from normal people of health examination were included as control group during the corresponding period. A total of 5 ml fasting peripheral blood sample was extracted from each individual. The IL-13 levels were determined by enzyme-linked immunosorbent assay (ELISA). IL-13 gene polymorphisms in+ 1923 C/T site and+ 2044 site were genotyped in these two groups by using polymerase chain reaction (PCR) combined with gene sequencing methods. About 7 days after admission, thirty patients with improved condition among the 43 patients were included as bronchiectasis improvement group, all had the extraction of 3 ml peripheral blood for IL-13 detection determined by ELISA. The expression of serum IL-13 and gene polymorphisms between bronchiectasis group and control group were analyzed statistically. The changes of serum IL-13 between bronchiectasis group and bronchiectasis improvement group were also analyzed statistically. Results: The serum IL-13 level was lower in the bronchiectasis group in acute exacerbation period than that of the healthy controls [(31.1±26.3) vs (70.6±53.6) μg/L, P<0.05]. There was no significant difference of the genotype distribution in + 1923C/T site of IL-13 gene between the two groups (χ(2)=0.915, P>0.05). In the bronchiectasis group, the C and T allele frequencies at+ 1923 site of IL-13 gene were 79.1% and 20.9%, respectively, and its single nucleotide polymorphism (SNP) was in strong linkage disequilibrium with the SNP IL-13+ 2044G/A site (R(2)=0.835, P<0.001). There was no significant difference of the serum IL-13 between allele T_ groups and allele CC group, and also no significant difference between allele A_ groups and allele GG group (P>0.05). Conclusion: The IL-13 levels decreased specifically in the bronchiectasis group in acute exacerbation period, but IL-13+ 1923C/T and+ 2044G/A polymorphisms are not significantly related to the susceptibility of bronchiectasis.

Development of a nomogram for predicting the risk of anastomotic leakage after a gastrectomy for gastric cancer. Eur J Surg Oncol 2016; 43:485-492. [PMID: 28041649 DOI: 10.1016/j.ejso.2016.11.022] [Citation(s) in RCA: 21] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Revised: 09/16/2016] [Accepted: 11/30/2016] [Indexed: 12/16/2022] Open
Abstract
AIMS To investigate the incidence of and factors associated with anastomotic leakage (AL) following gastrectomy for gastric cancer. METHODS We retrospectively analyzed 3632 patients who underwent a laparoscopic gastrectomy or open gastrectomy for gastric cancer. A logistic regression model was used to identify the determinant variables, and a nomogram for AL was developed. RESULTS A total of 3632 patients were included in the study, 50 of whom (1.4%) developed AL. Postoperative deaths occurred in 6 (0.2%) patients with AL failure to rescue. Esophagojejunal AL (27/50) and Billroth I AL (20/50) were the most common types of AL. Gastrografin swallow was the main diagnostic method. The diagnosis was made a median of 9 days postoperatively. The median healing time for AL was 34.5 days. Of the 50 AL patients, 56% of patients could be managed nonsurgically, whereas 28% of patients required percutaneous radiologic drainage, 6% of patients were treated by endoscopy, and 10% of patients required a second surgery. A multivariate analysis showed the following adverse risk factors for AL: age ≥65 years, hemoglobin ≤8.0 g/dL and malnourishment. A multivariable model for AL showed a strong optimism-adjusted discrimination (concordance index, 0.675). The 5-year overall survival rates for patients without or with AL were 59.4% and 67.4%, respectively (p = 0.354). CONCLUSIONS AL was infrequent but was more prevalent in patients with age ≥65 years, hemoglobin ≤8.0 g/dL and malnourishment. We created a novel nomogram that can provide individualized prediction of AL in patients after a gastrectomy for gastric cancer, which may help clinicians in making treatment decisions.

Abstract
BACKGROUND Recurrent aphthous ulceration (RAU) is one of the most common oral mucosal diseases, some of which may be secondary to haematologic deficiencies. This meta-analysis aims to evaluate the association between haematologic deficiencies and RAU. MATERIALS AND METHODS Case control studies were identified using a predefined search strategy that compared the difference in haematologic deficiencies between a RAU group and a control group. A meta-analysis was performed to estimate the combined odds ratios (ORs) and 95% confidence intervals (95% CIs) in a fixed-effects model and a random-effects model, as appropriate. RESULTS In this meta-analysis, nine case control studies, including total 710 cases in RAU groups and 602 cases in control groups, were considered eligible for inclusion. Overall, the combined results based on all studies showed that the rate of haematinic deficiencies was significantly high in the RAU group (vitamin B12: OR=3.75, 95% CI: 2.38-5.94; folic acid: OR=7.55, 95% CI: 3.91-14.60; ferritin: OR=2.62, 95% CI: 1.69-4.06; and haemoglobin: OR=1.77, 95% CI: 1.12-2.80). CONCLUSION This meta-analysis suggests that haematologic deficiencies could be a significant risk factor for RAU. Thus, screening and treating any haematologic deficiencies may play an important role in preventing the occurrence of RAU.

Abstract
The present study compared the roles of valence and arousal, proposed by the dimensional models of emotions, in recognizing emotional expressions. It was hypothesized that the dimension of valence, due to its functional significance, would be more salient in the recognition of emotional expressions than the dimension of arousal would be. The results of the current study supported this hypothesis. The participants in all age groups were more accurate and quicker in recognizing an emotion when the expression was paired up with another emotional expression that was different in the polarity of the valence dimension than with this similar polarity difference in the arousal dimension. The insignificant difference in recognizing the positive and negative emotional expressions in the group of elders also rejected the Socio-Emotional Selectivity Theory.
