Abstract
Interleukin-1β (IL-1β) is the prototypic pro-inflammatory cytokine, whose functions are mediated through interaction with its receptors (IL-1R1 and IL-1R2). Herein, we cloned the full-length cDNA and genomic DNA of IL-1β and IL-1R2 in the Asian swamp eel (Monopterus albus). The eel IL-1β cDNA encodes a putative polypeptide of 246 amino acids. The protein sequence includes a typical IL-1 family signature, but lacked an interleukin-converting enzyme cleavage site. The genomic DNA of eel IL-1β was 2520 bp and comprised five exons and four introns. The eel IL-1R2 cDNA encoded a putative propeptide of 423 amino acid residues, comprising a signal peptide, a transmembrane region and two Ig-like domains in the extracellular region. Similar to other vertebrates, the genomic DNA of the eel IL-1R2 has nine exons and eight introns. Real-time PCR analysis indicated that IL-1β and IL-1R2 were constitutively expressed in all tissues, especially in the liver and immune-related organs. After infection with Aeromonas hydrophila, the transcript levels of IL-1β and IL-1R2 were induced in the head kidney and spleen, reaching their highest levels at 6 h post injection. In vitro, IL-1β and IL-1R2 mRNA levels were also upregulated rapidly at 1h post infection with A. hydrophila. Furthermore, acanthocephalan Pallisentis (Neosentis) celatus could induce the expression of both genes in the head kidney and intestine. In infected intestines, the transcript levels of IL-1β and IL-1R2 were increased by 21.4-fold and 20.8-fold, respectively, relative to the control. The present study indicated that IL-1β and IL-1R2 play an important role in inflammation and host defense, especially in the antiacanthocephalan response.

Abstract
For cancer cells to proliferate, a balance must be built between biomass-forming, glucose-metabolized intermediates and ATP production. How intrinsic glucose carbon flow regulates this balance remains unclear. Here we show that mitochondrial phosphoenolpyruvate carboxykinase (PCK2), the hub molecule linking tricarboxylic acid (TCA) cycle, glycolysis and gluconeogenesis by conversion of mitochondrial oxaloacetate (OAA) to phosphoenolpyruvate, regulates glucose carbon flow direction in stem-like cells that repopulate tumors (tumor-repopulating cells (TRCs)). PCK2 downregulation accelerated biosynthesis and transportation of citrate from mitochondria to the cytosol, leading to cytosolic glucose carbon flow via OAA-malate-pyruvate and acetyl-CoA-fatty acid pathways in TRCs. On the other hand, downregulating PCK2 hindered fumarate carbon flows in TCA cycle, leading to attenuated oxidative phosphorylation. In pathological terms, PCK2 overexpression slowed TRC growth in vitro and impeded tumorigenesis in vivo. Overall, our work unveiled unexpected glucose carbon flows of TRCs in melanoma that have implications for targeting metabolic aspects of melanoma.

Abstract
Objective: To investigate the value of means of surfaces with nonhomogeneity (MSN) in esti-mating the incidence of pneumoconiosis. Methods: Based on the principal component analysis, all counties (districts) of Hebei Province, China, were divided into three categories according to the degree of pneumoconiosis hazards and the MSN model was used to estimate the incidence rate of pneumoconiosis and the number of pneu-moconiosis cases using the data of the incidence of pneumoconiosis in 2010. Results: With reference to the appli-cation requirements of the MSN model, results of the principal component analysis, and expert experience, the 172 counties (districts) in Hebei Province were divided into three categories with mild, moderate, and severe pneumoconiosis hazards. There were 74, 61, and 49 counties in the above categories, respectively, and 12, 12, and 25 counties were selected from them, respectively. The estimated number of pneumoconiosis cases in Hebei Province was 2105, and the incidence rate was 261.5 per hundred thousand, with a standard error of esti-mation of 389.9 per hundred thousand. Conclusion: The MSN model provides a new thought and method for es-timating the number of pneumoconiosis cases.

Abstract
OBJECTIVE To investigate the quality of life and its related factors among HIV/AIDS patients from HIV serodiscordant couples in Zhoukou city of Henan province. METHODS During January to May in 2015, by the convenience sample, World Health Organization Quality of Life Questionnaire for Brief Version (WHOQOL-BREF) (Chinese version) and a self-edited questionnaire were used to investigate 1 251 HIV/AIDS patients who were confirmed with HIV positive by local CDC, registered in"HIV serodiscordant family" and agreed to participate in a face-to-face interview with above 18 year-old based on the local CDC , township hospitals and village clinics of 9 counties and 1 district of Zhoukou city, excluding the HIV/AIDS patients who were in divorce, death by one side, unknowing about his HIV status, with mental illness and disturbance of consciousness, incorrectly understanding the content of the questionnaire, and reluctant to participate in this study. The scores of quality of life of physical, psychological, social relations, and environmental domain were calculated. The related factors of the scores of different domains were analyzed by Multiple Two Classification Unconditioned Logistic Regression. RESULTS The scores of investigation objects in the physical, psychological, social relations, and environmental domain were 12.00± 2.02, 12.07 ± 2.07, 11.87 ± 1.99, and 11.09 ± 1.84, respectively. The multiple Unconditioned Logistic Regression analysis indicated that age <40 years, on ART and no other sickness in last two weeks were beneficial factors associated with physical domain with OR (95%CI): 0.61 (0.35-1.06), 0.52 (0.30-0.90), and 1.66 (1.09-2.52), respectively. The possibility of no poverty and no other sickness in last two weeks increased to 0.15(0.09-0.26) and 1.57(1.06-2.33) times of those who was in poverty and with other sickness in last two weeks in physical domain. The possibility of participants who were below 40 years old and with children increased to 0.58 (0.34-0.98) and 0.37 (0.23-0.57) times of who were above 40 years old and without children in psychological domain. The factors of with AIDS related symptoms, no children and with other sickness in last two week were found to be significantly associated with environmental domain with OR (95%CI): 0.65 (0.48-0.88), 0.66 (0.51-0.85), and 0.65 (0.51-0.84), respectively . CONCLUSION The scores of every domain of quality of life in HIV serodiscordant couples of Zhoukou city were good. Age, whether having AIDS related symptoms, whether to accept ART , children, status of poverty, and whether suffering from other diseases in last two weeks were the main factors associated with the quality of life.

Different expression of sodium-iodide importer (NIS) between lactating breast and thyroid tissues may be due to structural difference of thyroid-stimulating hormone receptor (TSHR).

Abstract
OBJECTIVE Thyroid-stimulating hormone (TSH) binds TSH receptor (TSHR) on thyroid cell membranes, which will lead activation of cyclic adenosine 3',5'-monophosphate/protein kinase A signaling pathway. Through this pathway, TSHR regulates the expression of sodium-iodide symporter (NIS) to complete iodine intake. In recent studies, it is found that TSHR is widely expressed in a variety of extra-thyroidal tissues. TSHR expressions as well as distribution in normal mammary gland tissues have not been reported. The physiological mechanism of the TSHR in the extra-thyroidal tissues has also been controversial. METHODS In this study, immunohistochemistry and immunofluorescence were used to characterize the expression distribution of TSHR protein in lactating breast. DNA sequence of TSHR cDNA from mice lactating breast was determined and then compared with TSHR cDNA from mice thyroidal tissue. RESULTS A 173 amino acid (AA) fragment deletion was found in the extra-cellular domain of lactating breast TSHR. The expression levels of NIS mRNA were compared between two tissues, and the level of NIS mRNA in lactating breasts was lower than the one in thyroidal tissues. CONCLUSION The lower expression of NIS in lactating breast may be due to the 173 AA deletion in the TSHR resulting the lower binding of TSH to the TSHR. For the first time, this finding may explain the reason of the lower NIS expression in lactating breast.

Abstract
Lung cancer is the leading cause of cancer-related death in the world. Several genome-wide association studies (GWAS) have identified TERT-CLPTM1L as plausible causative locus for lung cancer development. This study aimed to investigate the associations of genetic variations in TERT-CLPTM1L and the expression level of TERT with the survival of early stage non-small cell lung cancer (NSCLC) patients. We selected three single-nucleotide polymorphisms of TERT-CLPTM1L (rs2853669, rs2736108 and rs31490) and genotyped in 140 early stage NSCLC patients by TaqMan assay. Associations between these variations and survival outcome of early stage NSCLC patients were further investigated. We also used TCGA data to evaluate the associations of TERT messenger RNA (mRNA) expression and survival outcome of early stage NSCLC patients. Survival analysis showed that, compared with early NSCLC patients carrying TERT rs2853669 TT+TC genotypes, patients with rs2853669 CC genotype had significantly longer median survival time (MST=102.2 vs 52.4 months; log-rank P=0.028) and lower death risk [hazard ratio (HR) with 95% confidence interval (CI))=0.38(0.17-0.82), P=0.014]. Early NSCLC patients carrying TERT rs2736108 AA genotype had significantly shorter MST (MST=29.0 vs 63.3 months; log-rank P=0.020) and increased death risk [HR (95% CI)=2.22(1.01-5.80), P=0.046], when compared with patients carrying rs2736108 GG genotypes. TCGA data revealed that early NSCLC patients with higher expression level of TERT mRNA in lung tumor tissues had a longer MST and decreased death risk than those with low expression level of TERT mRNA [MST=54.4 vs 49.0 months; log-rank P=0.041; adjusted HR (95% CI)=0.68(0.50-0.94)]. These findings may add potential evidence to understand the prognostic value of TERT and provide a new prospect of individualized prevention and treatment for early stage NSCLC.

Abstract
Fibroblast growth factors (FGFs) play important roles in angiogenesis, wound healing, embryonic development, and endocrine signaling pathways. Increasingly, recent studies have reported aberrant FGF expression in various malignancies. However, the involvement of FGFs in cervical carcinoma pathogenesis remains unclear. We aimed to investigate expression of acidic (aFGF) and basic FGF (bFGF) in patients with this disease, and assess their effects on cervical cancer cell proliferation. Twenty cervical cancer patients and 10 cervical intraepithelial neoplasia (CIN) patients were recruited, and 10 cancer-free individuals were included as controls. Reverse transcription-polymerase chain reaction and western blotting were employed to detect FGF mRNA and protein levels, respectively. Furthermore, HeLa cells were treated with FGFs and subjected to thiazolyl blue tetrazolium bromide assays to quantify proliferation. Compared with CIN and normal cervical tissues, aFGF and bFGF mRNA and protein levels were significantly elevated in cervical carcinomas (P < 0.05). CIN tissues exhibited higher expression of these FGFs than normal tissues (P < 0.05). Moreover, their mRNA levels were increased in advanced cancer stages (P < 0.05), although no significant difference was detected between tumors of different differentiation grades in this regard (P > 0.05). HeLa cell proliferation increased in an aFGF- and bFGF-dose-dependent manner (P < 0.05), the latter exerting a more potent proliferative influence, with its effect peaking at 75 ng/mL. aFGF and bFGF were highly expressed in cervical cancer tissues and their levels positively correlated with clinical stage. Both facilitate proliferation of cervical carcinoma cells and are implicated in cancer pathogenesis and progression.

Abstract
To introduce a method of increasing the width of alveolar bone. The patient, who needed dental implantation and had narrow alveolar bone, was selected. The preparation of mucosa-periosteal bone flap included two surgeries. The first surgery was corticotomy, which made a square cortex cut on narrow alveolar bone region. The second surgery was performed four weeks after the first one, which split the alveolar bone and inserted implants. Artificial bone and/or autologous bone was filled between inner and outer bone plate, and collagen membrane and platelet-rich fibrin membrane were used to cover the wound. This technique maintained the blood supply of labial(buccal) alveolar bone completely. Artificial bone and/or autologous bone graft contacted with cancellous bone directly and led to better bone growth and bone formation. Alveolar bone mucosa-periosteal bone flap can maintain the labial(buccal) alveolar bone effectively and avoid bone resorption.

Abstract
The foil resistive bolometer diagnostic on experimental advanced superconducting tokamak has been upgraded partly with a new generation of detectors. The new detectors have faster response time. However, the microwave interference is still a serious issue for the bolometer system. The system response to microwave is tested, and the test results show that the closed Wheatstone bridge circuit in the detector is the most sensitive component to high power microwave field. Simulation results of microwave transmission by the high frequency structure simulator software and shielding design are also presented.

Abstract
Objective: To investigate the application of principal component analysis in comprehensive indicator screening for pneumoconiosis in different regions. Methods: A principal component analysis was performed for the data of 11 factors associated with the prediction of pneumoconiosis hazard and collected in the investigation on occupational health status conducted in 172 counties (districts) in Hebei, China. The degree of pneumoconiosis hazard in different regions was obtained and intuitively presented by GIS. Results: The eigenvalues of 5 principal components of pneumoconiosis were 4.103, 2.341, 0.981, 0.943, and 0.726, respectively, and the contribution values were 37.299%, 21.286%, 8.919%, 8.572%, and 6.596%, respectively. According to the comprehensive value of principal components, GIS Natural Breaks was used to divide the degree of pneumoconiosis hazard in 172 counties (districts) in Hebei into mild, moderate, and severe grades. Of all the counties, 46 had severe pneumoconiosis hazard, 69 had moderate pneumoconiosis hazard, and 57 had mild pneumoconiosis hazard, and the ranges of the score of principal components were 0.30-1.15, -0.24 to 0.27, and -0.69 to -0.25, respectively. Conclusion: Principal component analysis can optimize the comprehensive indicators for the evaluation of regional pneumoconiosis. The comprehensive score of principal components can quantify and intuitively show the degree of pneumoconiosis hazard in different regions. Tangshan, Chengde, Shijiazhuang, and Handan have the most severe pneumoconiosis hazard.

Abstract
OBJECTIVE To observe the effect of expanded flap containing cervical cutaneous branch of transverse cervical artery (TCA) on reconstruction of postburn facial scar contracture deformity. METHODS Six patients with postburn facial scar contracture deformity, hospitalized from September 2011 to January 2016, with the scar area ranging from 12 cm×10 cm to 20 cm×15 cm, were reconstructed with expanded flap containing cervical cutaneous branch of TCA. One expander of 300 mL or 350 mL implanted in anterior pectoral area was injected for excessive expanding; one patient was conducted with expansion in both sides of the anterior pectoral area. The volume of expansion varied from 1 260 to 2 010 mL after 6 to 15 months. Two flaps were delayed for their poor blood supply. After expansion, the flaps with the area ranging from 20 cm×7 cm to 25 cm×9 cm were transferred with no tension to cover the wounds after scar excision. The donor site was closed directly. Three to four weeks later, the vascular pedicle was dissected combined with local reconstruct surgery. RESULTS All the flaps survived, with two wounds suffered delayed healing. During the follow-up for 4 to 15 months, the flaps were thin and soft with good sensation and color close to the facial skin. CONCLUSIONS Expanded flap containing cervical cutaneous branch of TCA is a good choice for reconstruction of postburn facial scar contracture deformity because of its good texture and color, thin thickness, as well as it can provide large avaliable area while causing less injury to the donor site.

Abstract
We propose to generate a single-mode-squeezing two-mode squeezed vacuum state via a single χ(2) nonlinear photonic crystal. The state is favorable for existing Gaussian entanglement distillation schemes, since local squeezing operations can enhance the final entanglement and the success probability. The crystal is designed for enabling three concurrent quasi-phase-matching parametric-down conversions, and hence relieves the auxiliary on-line bi-side local squeezing operations. The compact source opens up a way for continuous-variable quantum technologies and could find more potential applications in future large-scale quantum networks.

Abstract
OBJECTIVE To evaluate the clinical significance of serum albumin (ALB) levels in the early evaluation and prognosis of preterm infants in the neonatal intensive care units (NICUs). MATERIALS AND METHODS The authors collected and retrospectively analyzed complete clinical records of preterm infants admitted to the NICU from July 2012 to March 2013. The cases were divided into three groups according to their ALB levels: ≥ 30 g/L, 25-30 g/L, and ≤ 25 g/L. RESULTS The mean gestational age in the ≤ 25 g/L ALB group was significantly higher than that in the ≥ 30 g/L ALB group [(33.41 ± 2.15) weeks] (p < 0.05). The prealbumin, blood platelet, and blood urea nitrogen in the ≤ 25 g/L ALB group were significantly lower than those in the ≥ 30 g/L ALB group (p < 0.05). In addition, serum lactate in the ≤ 25 g/L ALB group was significantly higher than that in the ≥ 30 g/L ALB group (p < 0.05). CONCLUSION Serum ALB level increased with increasing gestational age. Lower ALB levels were associated with more perinatal complications, damage to multiple organs, more severe cases, and mechanical ventilation, which resulted in longer hospital stays and poorer prognoses.

Abstract
OBJECTIVE The aim of this study was to investigate the impacts of late gestational liver dysfunction and its impact on pregnancy outcomes. MATERIALS AND METHODS The patients hospitalized for liver dysfunction in their late pregnancy between 2010-2012 were set as the observation group, and the pregnant women with normal liver function at the same period were randomly selected and set as the control group. The impacts towards the pregnancy outcomes were compared between these two groups and the impacts of different-degree transaminase increasing towards the pregnancy outcome were analyzed. RESULTS The incidence rates of cesarean section, post-partum hemorrhage, fetal distress, premature birth, premature rupture of membranes (PROM) of the observation group and the transaminase-severely-increased group (the severe group) were higher, and the differences were statistically significant (p < 0.01 or < 0.05); while only the cesarean rate of the mild and moderate group was significantly different from the control group (p < 0.01 or < 0.05). The ratios of intrahepatic cholestasis in pregnancy (ICP), gestational hypertension + HELLP syndrome, acute fatty liver in pregnancy (AFLP) of the severe group were higher than the mild and moderate group, and the differences were statistically significant; the non-alcoholic fatty liver disease (NAFLD) group and the unknown cause group mainly showed a mildly increased transaminase; the distributions of viral hepatitis in pregnancy (VHP), post-viral-hepatitis-B cirrhosis, biliary tract disease, and infected toxic liver dysfunction in different-degree increased transaminase groups had no significant difference. CONCLUSIONS Liver dysfunction in later pregnancy, especially with severe transaminase increase, might significantly increase the risk of adverse maternal events. The major causes of severe liver dysfunction in late pregnancy were ICP, gestational hypertensive disorders, and AFLP.

Abstract
RNA-Seq technology has been widely applied to transcriptomics, genomics, molecular marker development, and functional gene studies. In the genome, microsatellites are simple sequence repeats (SSR) with a high degree of polymorphism that are used as DNA markers in many molecular genetic studies. Using traditional methods such as magnetic bead enrichment, only a few microsatellite markers have been isolated. Coilia nasus is an anadromous, small-to-moderately sized fish species that is famous as an important fishery resource. Here, we have identified a large number of microsatellites from the fish brains by using Illumina sequencing. About 20 million Illumina reads were assembled into 148,845 unigenes. A total of 13,038 SSR motifs were identified via analysis of 3,958,293,117 (3.96 Gb) nucleotides to produce a comprehensive transcript dataset for the C. nasus brain, including mono-, di-, tri-, tetra-, and penta-repeat motifs. The most abundant type of repeat motif was di-nucleotide (42.97%), followed by mono-nucleotide (38.86%), tri-nucleotide (16.21%), tetra-nucleotide (1.83%), and penta-nucleotide (0.05%) repeat units, which is similar to the results obtained in studies in other species. These data provide a base of sequence information to improve molecular-assisted markers to study C. nasus genetic diversity.

Abstract
In the present study, serum samples from 402 sheep and 216 goats were collected from 5 counties in Jinzhou from August to October 2012 and antibodies to Toxoplasma gondii were detected by modified agglutination test (MAT). Overall, 104 (16.8%) had antibodies to T. gondii with antibody titres of 1:25 to 1:800. Seropositive samples were distributed in all the 5 counties and seroprevalences of T. gondii varied significantly with flock size, age and rearing system, but not with breed, gender and farm location. The seroprevalences in small farms (18.3%, 95/518, 95% confidence interval [CI], 15.0-21.7%) were statistically higher than that in large farms (9%, 9/100, 95% CI, 3.4-14.6%) (P < 0.05), older animals were statistically higher than that in younger animals (P < 0.01). The prevalence in extensively and semi intensively raised samples was statistically higher than that in intensively raised animals (P < 0.01). Small flock size and extensive rearing system are the potential risk factors for the prevalence of Toxoplasma infection in sheep and goats in Jinzhou. This is the first report of T. gondii infection in sheep and goats in Jinzhou, northeastern China, and of an association of seropositivity to T. gondii and the risk factors.
