Abstract
Abstract
Soot formed during the rich combustion of fossil fuels is an undesirable pollutant and health hazard. A newly developed Monte Carlo method is used to simulate the soot formation in a counterflow diffusion flame of ethylene. The simulation uses a new reaction mechanism available in literature, which focuses on modeling the formation of large polycyclic aromatic hydrocarbons (PAHs) up to coronene (C24H12). Nascent soot particles are assumed to form from the collision of eight different PAH molecules. Soot surface growth includes the hydrogen-abstraction-C2H2-addition mechanism and the condensation of the PAHs. Soot coagulation is in the free-molecular regime because particles are small (not more than a hundred nanometer). The coupling between vapor consumption and soot formation is handled by an interpolative moment method. Soot particle diffusion is found negligible throughout the counterflow flame, except for a very narrow region right around the stagnation plane. The soot particle size distribution (PSD) generally exhibits a bimodal shape. The first peak corresponds to a large number of nascent particles, while the second peak results from the competition between nucleation and coagulation. Surface growth affects the PSD quantitatively, but does not change the modality. A comparison with experimental data is also provided.

Abstract
This work sought to determine the fitness responses and energy expenditure (EE) following once-weekly hill climbing for 16 weeks on different slopes. A cohort of 98 healthy, sedentary subjects (49 female, 49 male) completed the program at their preferred climbing pace. Body composition, resting metabolic rate (RMR) and VO2max were measured. EE was measured on 4 slopes (11.6°, 19.9°, 14.9°, and 28.6°) at the subjects' preferred speed. In males, weight, body mass index, fat mass significantly decreased (P<0.05), and RMR showed an increasing trend, but the difference was not significant (P=0.051). In females, the muscle mass increased significantly, and fat (%) and fat mass significantly decreased (P<0.05). Absolute and relative of VO2max, ventilation (VE) improved significantly in both sexes (P<0.01). Energy expenditure was similar on different slopes, but shows gender-specific values of approximately 50.4 and 33.6 kJ/min for males and females, respectively. The regression equation of EE (kJ/min)=[1.724×(female=1, and male=2)+(-0.072×age)+0.106×weight+0.024×HR+0.136×slope+1.487×velocity]×4.2. In conclusion, hill climbing at a subjects' preferred velocity is a vigorous-intensity physical activity for energy cost and, performed once weekly, enhances cardiorespiratory fitness and reduces fat mass, therefore making it a viable exercise for most people.

Abstract
OBJECTIVE This study investigates the human papillomavirus (HPV) infection rate in female genital tracts, as well as the HPV genotype distribution and HPV correlation with cervical disease in Weihai, Shandong Province, China. MATERIALS AND METHODS A random sample of 9,460 volunteers was simultaneously screened using gene chips and examined by ThinPrep liquid-based cytology test (TCT). Cervical biopsy samples were collected from women with positive HPV-DNA and abnormal TCT for pathological diagnosis. RESULTS The overall HPV prevalence was 6.93% (656 of 9,460). A total of 753 subjects were infected with HPV subtypes (including multiple HPV infections). Of those with infections, 688 were infected with high-risk (HR) types (91.37%), and 65 were infected with low-risk subtypes (8.63%). The single-infection rate was 63.1%.The prevalence rates of HPV in women aged 20 to 39 years and 40 to 59 years were 7.29% and 6.71%, respectively. The most common genotype was HPV16. The HR genotypes were associated with cervical diseases such as atypical squamous cells of undetermined significance (ASCUS) (37.9%), atypical squamous cells high grade (ASC-H) (42.5%), low grade squamous intraepithelial lesion (LSIL) (50%), and high grade squamous intraepithelial lesion HSIL (66.7%). Cervical biopsy results show that the HPV detection rate increased in the following biopsy samples: cervical intraepithelial neoplasia (CIN) I (74.11%), CIN II (84.31%), CIN III (90.32%), and squamous-cell carcinoma (SCC) (100%). CONCLUSIONS The HPV infection rate with associated cervical disease in Weihai is equal to those in foreign countries but is lower than the average rate in China. The prevalence of HPV was higher in young people. The most common HPV genotype was 16, followed by 52 and 58. HR HPV is the most probable infection factor for cervical diseases.

Abstract
The application potential of four duckweed strains from four genera, Wolffia globosa 0222, Lemna japonica 0223, Landoltia punctata 0224 and Spirodela polyrhiza 0225, were compared in four parallel pilot-scale wastewater treatment systems for more than 1 year. The results indicated that each duckweed strain had unique potential advantages. Unlike L. japonica 0223 and La. punctata 0224, which grow throughout the year, S. polyrhiza 0225 and W. globosa 0222 do not survive cold weather. For year round performance, L. japonica 0223 was best not only in dry biomass production (6.10 g·m(-2) ·day(-1) ), but also in crude protein (35.50%), total amino acid (26.83%) and phosphorus (1.38%) content, plus recovery rates of total nitrogen (TN), total phosphorus (TP) and CO2 (0.31, 0.085 and 7.76 g·m(-2) ·day(-1) , respectively) and removal rates of TN and TP (0.66 and 0.089 g·m(-2) ·day(-1) , respectively). This strongly demonstrates that L. japonica 0223 performed best in wastewater treatment and protein biomass production. Under nutrient starvation conditions, La. punctata 0224 had the highest starch content (45.84%), dry biomass production (4.81 g·m(-2) ·day(-1) ) and starch accumulation (2.9 g·m(-2) ·day(-1) ), making it best for starch biomass production. W. globosa 0222 and S. polyrhiza 0225 showed increased flavonoid biomass production, with higher total flavonoid content (5.85% and 4.22%, respectively) and high dominant flavonoids (>60%). This study provides useful information for selecting the appropriate local duckweed strains for further application in wastewater treatment and valuable biomass production.

Abstract
Metabolic syndrome (MS), a series of physiological and metabolic disorders caused by insulin resistance, combines clinical syndrome of abdominal obesity, diabetes or impaired glucose regulation, dyslipidemia, hypertension and other metabolic diseases. Several studies have found that multiple single nucleotide polymorphism (SNP) exists in adiponectin gene (ADIPOQ) and some unusual mutations might be related to hypoadiponectinemia and MS. This study aims to explore the relationship between ADIPOQ gene polymorphism and lipid levels and diabetes. A total of 1,049 confirmed MS cases were selected for research. From the perspective of potential functional SNPs of ADIPOQ gene, tag SNPs, combined with environmental factors, we studied the relationship between ADIPOQ gene polymorphism and phenotype (serum adiponectin level) and further analyzed the correlation of ADIPOQ gene polymorphism and metabolic syndrome components so as to clear the relationship between ADIPOQ gene polymorphism and lipid levels and diabetes and at the same time provide a scientific basis for preventing primarily MS etiology and screening high-risk groups.

Abstract
The ovarian differentiation, morphogenesis and expression of some putative gonadal development-related genes were analysed in the ricefield eel Monopterus albus, a protogynous hermaphroditic teleost with a single elongate ovary. At c. 1 day post-hatching (dph), the gonadal ridge was colonized with primordial germ cells (PGCs) at the periphery and transformed into the gonadal primordium, which appeared to contain two germinal epithelia. At c. 7 dph, four ovarian cavities appeared in the gonadal tissue with two in each germinal epithelial compartment, and the indifferent gonad might have begun to differentiate into the ovary. The oocytes at the leptotene stage in meiosis I appeared at c. 14 dph, and oocytes at the diplotene stage at c. 30 dph. As development proceeded, the connective tissue separating the two germinal epithelia disappeared, and two of the four ovarian cavities collapsed into one. At 60 dph, the gonad had already taken the shape as observed in the adults. One outer and two inner ovarian cavities could be easily recognized, with slightly basophilic primary growth oocytes usually residing close to the outer ovarian cavity. The expression of cyp19a1a and erb in the early gonad was detected at 6 dph. The abundant expression of foxl2 coincided with the up-regulation of cyp19a1a at 8 dph onwards. The expression of dmrt1 isoforms was not detectable until 8 dph for dmrt1a and dmrt1b and until 33 dph for dmrt1d. The earlier appearance of cyp19a1a compared to dmrt1 transcripts in the indifferent gonad may contribute to the initial differentiation of the gonad towards the ovary in M. albus.

Abstract
BACKGROUND We investigated risk factors for locoregional recurrence (lrr) in breast cancer patients with 4 or more positive axillary lymph nodes receiving postmastectomy radiotherapy (pmrt). METHODS Medical records (1998-2007) were retrospectively reviewed for the population of interest. The Kaplan-Meier method was used to calculate the survival rate; Cox regression models were used for univariate and multivariate analysis of predictors of breast cancer lrr. RESULTS The study enrolled 439 patients. Median duration of follow-up was 54 months. The 5-year rates of locoregional recurrence-free survival (lrrfs), distant metastasis-free survival (dmfs), and breast cancer-specific survival (bcss) were 87.8%, 59.5%, and 70.7% respectively. In patients with lrr and no concomitant metastasis, and in those without lrr, the 5-year rates of dmfs were 21.1% and 65.7% respectively (p < 0.001), and the 5-year rates of bcss were 34.5% and 76.4% respectively (p < 0.001). Univariate analysis showed that menopausal status (p = 0.041), pN stage (p = 0.006), and positivity for her2 [human epidermal growth factor receptor 2 (p = 0.003)] or the triple-negative disease subtype (p < 0.001) were determinants of lrrfs. Multivariate analysis showed that pN3 stage [hazard ratio (hr): 2.241; 95% confidence interval (ci): 1.270 to 3.957; p = 0.005], her2 positivity (hr: 2.705; 95% ci: 1.371 to 5.335; p = 0.004), and triple-negative disease subtype (hr: 4.617; 95% ci: 2.192 to 9.723; p < 0.001) were independent prognostic factors of lrrfs. CONCLUSIONS In breast cancer patients with 4 or more positive axillary lymph nodes who undergo pmrt for breast cancer, lrr significantly influences survival. Patients who developed lrr carried a high risk for distant metastasis and death. Pathologic stage (pN3), her2 positivity, and the triple-negative disease subtype are risk factors that significantly influence lrrfs.

Abstract
BACKGROUND Alterations in gray matter (GM) are commonly observed in schizophrenia. Accumulating studies suggest that the brain changes associated with schizophrenia are distributed rather than focal, involving interconnected networks of areas as opposed to single regions. In the current study we aimed to explore GM volume (GMV) changes in a relatively large sample of treatment-naive first-episode schizophrenia (FES) patients using optimized voxel-based morphometry (VBM) and covariation analysis. METHOD High-resolution T1-weighted images were obtained using 3.0-T magnetic resonance imaging (MRI) from 86 first-episode drug-naive patients with schizophrenia and 86 age- and gender-matched healthy volunteers. Symptom severity was evaluated using the Positive and Negative Syndrome Scale (PANSS). GMV was assessed using optimized VBM and in 16 regions of interest (ROIs), selected on the basis of a previous meta-analysis. The relationships between GMVs in the ROIs were examined using an analysis of covariance (ANCOVA). RESULTS The VBM analysis revealed that first-episode patients showed reduced GMV in the hippocampus bilaterally. The ROI analysis identified reductions in GMV in the left inferior frontal gyrus, bilateral hippocampus and right thalamus. The ANCOVA revealed different patterns of regional GMV correlations in patients and controls, including of inter- and intra-insula, inter-amygdala and insula-postcentral gyrus connections. CONCLUSIONS Schizophrenia involves regional reductions in GMV and changes in GMV covariance in the insula, amygdala and postcentral gyrus. These findings were evident at the onset of the disorder, before treatment, and therefore cannot be attributable to the effects of chronic illness progression or medication.

Abstract
BACKGROUND Affective instability (AI) is poorly defined but considered clinically important. The aim of this study was to examine definitions and measures of AI employed in clinical populations. METHOD This study was a systematic review using the PRISMA guidelines. MEDLINE, Embase, PsycINFO, PsycArticles and Web of Science databases were searched. Also five journals were hand searched. Primary empirical studies involving randomized controlled trials (RCTs), non-RCTs, controlled before and after, and observational investigations were included. Studies were selected, data extracted and quality appraised. A narrative synthesis was completed. RESULTS A total of 11 443 abstracts were screened and 37 studies selected for final analysis on the basis that they provided a definition and measure of AI. Numbers of definitions for each of the terms employed in included studies were: AI (n = 7), affective lability (n = 6), affective dysregulation (n = 1), emotional dysregulation (n = 4), emotion regulation (n = 2), emotional lability (n = 1), mood instability (n = 2), mood lability (n = 1) and mood swings (n = 1); however, these concepts showed considerable overlap in features. A total of 24 distinct measures were identified that could be categorized as primarily measuring one of four facets of AI (oscillation, intensity, ability to regulate and affect change triggered by environment) or as measuring general emotional regulation. CONCLUSIONS A clearer definition of AI is required. We propose AI be defined as 'rapid oscillations of intense affect, with a difficulty in regulating these oscillations or their behavioural consequences'. No single measure comprehensively assesses AI and a combination of current measures is required for assessment. A new short measure of AI that is reliable and validated against external criteria is needed.

Abstract
Bovine papilloma is a chronic and proliferative skin and mucosal wart caused by Bovine papillomavirus (BPV). In June, 2013, a leaf-and flat-shaped wart disease was observed on the nipple skins in a cattle farm in Xinjiang. To diagnose the disease, we collected the diseased skins for pathological biopsy and DNA analysis by PCR amplification using a pair of degenerate primers FAP59 and FAP64. Sequencing and phylogenetic analysis showed that the infection was caused by a variant of BPV3 and putatively a new subtype of BPV (BPV/CHI-SW1, belonging to the Xi papillomavirus genus). This is the first report of mixed infection caused by variant of BPV3 and BPV (putatively new subtype) in China, and would be of importance for the molecular epidemiological study of the disease.

Abstract
OBJECTIVES Vitamin D receptor gene polymorphisms has been shown to be associated with systemic lupus erythematosus (SLE). Several studies have been published which have investigated the association between VDR gene polymorphisms with SLE risk, but the results have been inconclusive. The study was designed to investigate whether the vitamin D receptor gene polymorphisms are associated with the risk of SLE. METHODS A meta-analysis was conducted on associations between the vitamin D receptor gene polymorphisms and SLE using (1) allele contrast and (2) the recessive, (3) the dominant, and (4) the additive models. RESULTS A total of 11 case-control studies of 1683 patients and 1883 unrelated healthy individuals were included. The results of meta-analysis indicated that the BsmI and FokI polymorphisms are associated with increased risk of SLE. The overall ORs are 2.14 [95%CI (1.20-3.82), p=0.01] ( BB + Bb vs. bb) and 1.75 [95%CI(1.03-2.97), P=0.04]( FF + Ff vs. ff), respectively, while the ApaI and TaqI polymorphism were not associated. In subgroup analysis by ethnicity, the increased risk of SLE remained in the Asian subgroup for the BsmI and FokI polymorphism, whereas no significant association was found in other populations for other polymorphisms. CONCLUSIONS The current study suggested that the BsmI and FokI polymorphism are associated with increased risk of SLE, especially in the Asian population, but further studies are needed to confirm our results.

Abstract
It is generally believed that some inflammatory antigens can recognize Toll-like receptors on synovial fibroblasts (SFs) and then activate downstream signals, leading to the formation of RASFs and inducing rheumatoid arthritis (RA). The objective of the current work was to study on the hypothesis that outer PAMP (LPS) binds to the inner DAMP (HMGB1) and becomes a complex that recognizes TLRs/RAGE on SFs, thus initiating a signaling cascade that leads to the secretion of inflammatory cytokines and chemokines, production of tissue-destructive enzymes, and formation of RASFs, finally resulting in RA. Osteoarthritis synovial fibroblasts (OASFs) were co-cultured with HMGB1–LPS complex in vitro for five generations to induce the transformation of human SFs to RA-like SFs (tOASFs). Then, changes of tOASFs in cell cycle and apoptosis–autophagy balance were investigated in vitro, and the pathogenicity of tOASFs was evaluated in a SCID mouse model in vivo. In vitro cell cycle analysis showed more tOASFs passing through the G1/S checkpoint and moving to S or G2 phase. Flow cytometry and confocal microscopy showed that apoptosis was reduced and autophagy was enhanced significantly in tOASFs as compared with those in OASFs. The expression of certain receptors and adhesion molecules in tOASFs was upregulated. In vivo experiments showed that tOASFs attached to, invaded, and degraded the co-implanted cartilage. In addition, histochemistry showed excessive proliferation of tOASFs and the expression of matrix metalloproteinases (MMPs). Based on the above findings, we conclude that HMGB1–LPS complex could promote the formation of RASFs.

Abstract
In recent decades, nanoparticulate drug delivery systems have attracted extensive attention in cancer therapy for such appealing properties as small particle size, huge surface area, narrow size distribution and prolonged circulation time. Although several nanomedicines have successfully reached the clinical, evidences have proved that therapeutic efficacy isn't improved significantly, except for better toleration and less side effects. Given that the physiological abnormalities in tumors, multiple biobarriers need to be overcome before nanomedicines are delivered to the target site. Passive targeting nanoparticles ensure nanomedicines' extensive extravasation from tumor vessels via enhanced permeation and retention effect, but the diffusion distance is limited to 2-3 cell layer thicknesses. Active targeting nanoparticles tend to bind the peripheral cells of the tumor mass, hindering nanoparticles further penetration into the tumor core region. Therefore, how to improve the deep penetration of nanomedicines into tumors is a formidable task for achieving the desired anticancer therapeutic efficacy. This review demonstrates the penetration obstacles existing in tumor region for nanoparticles, summarizes the important properties of nanomedicines affecting tumor deep penetration and highlights the solutions to improve tumor deep penetration of nanoparticles.

Abstract
BACKGROUND Mesohepatectomy (MH) avoids unnecessary sacrifice of functional parenchyma compared with extended hepatectomy (EH). The aim of this study was to compare the results of MH with those of EH in the management of centrally located liver tumours (CLLTs). METHODS All patients with CLLTs treated by liver resection between 2005 and 2011 were enrolled in this retrospective study. The decision to use MH or EH was made on an individual basis. Outcomes of the procedures were compared and a classification system for MH was devised consisting of four types, with type IV representing the most complex procedure. RESULTS MH was performed in 292 patients and EH in 138. MH was associated with a longer duration of operation (P < 0.001), higher intraoperative transfusion rate (P < 0.001) and lower complication rates (P = 0.001) compared with EH. There were no significant differences in hepatic inflow occlusion rate (P = 0.075), blood loss (P = 0.241) and length of hospital stay (P = 0.804) between the two groups. Type IV lesions had the longest duration of operation, greatest blood loss, and highest intraoperative transfusion and morbidity rates (all P < 0.050). CONCLUSION MH is a feasible and safe alternative to EH in selected patients with CLLTs. The proposed classification system may be useful in guiding the surgical treatment of CLLTs.

Abstract
Ossification of the posterior longitudinal ligament (OPLL) is a condition of the spine that can cause paralysis by compressing the spinal cord. The aim of this study was to evaluate the possible role of nucleotide pyrophosphatase phosphodiesterase 1 gene (NPP1) polymorphism in the etiology and pathology of the OPLL in Chinese patients. DNA from patients with OPLL (N = 95) and without OPLL (N = 90) were genotyped for 4 NPP1 single-nucleotide polymorphisms (SNPs): A533C, C973T, IVS15-14T→C, and IVS20-11delT. An association study evaluated the relationship between specific SNP genotypes and susceptibility. We also evaluated whether genotypes of these SNPs were associated with disease severity and the probability of disease progression after surgery. The C973T and IVS15-14T SNPs were associated with the existence of the disease. The TT genotypes of C973T and IVS15→14T as well wild-type IVS20 (lack of deletion) were associated with more severe disease. Patients with the T deletion of IVS20 or the AA genotype of A533C had an approximately 3 times greater chance of not having than having disease progression after surgery. We concluded that the 4 SNPs analyzed appeared to have different effects on the etiology and pathology of OPLL. To our knowledge, this study is the first to investigate the relationship between these SNPs and disease progression after surgery. Our findings suggest that the presence of specific genotypes of the IVS20-11delT and A533C SNPs may predict disease outcome after surgical intervention.

Abstract
Insect immune responses are precisely regulated to maintain immune balance. In this study, the Fas-associated factor 1 (FAF1) gene of Locusta migratoria manilensis, a homologue of the caspar gene that functions as a specific negative regulator in the antibacterial immunity pathway, was cloned. Gene expression analysis showed that FAF1 was expressed throughout the developmental stages and in all tested tissues, but its transcription levels varied significantly. Thus, FAF1 appears to be tightly regulated and is probably involved in multiple physiological processes. In addition, the antimicrobial peptide gene prolixicin was cloned and characterized. After bacterial challenge, prolixicin was rapidly up-regulated, whereas FAF1 was markedly down-regulated. This result was consistent with the observation that prolixicin was hyperactivated when FAF1 was suppressed by RNA interference. Moreover, after bacterial infection, the survival rate of FAF1-knockdown locusts was much higher than that of the wild-type. Taken together, these findings strongly suggest that FAF1 shares a similar function as caspar in Drosophila and may be involved in the negative regulation of antibacterial immunity in locusts.

Abstract
Boiling Springs Lake (BSL) in Lassen Volcanic National Park, California, is North America's largest hot spring, but little is known about the physical, chemical, and biological features of the system. Using a remotely operated vessel, we characterized the bathymetry and near-surface temperatures at sub-meter resolution. The majority of the 1.2 ha, pH 2.2 lake is 10 m deep and 50-52 °C, but temperatures reach 93 °C locally. We extracted DNA from water and sediments collected from warm (52 °C) and hot (73-83 °C) sites separated by 180 m. Gene clone libraries and functional gene microarray (GeoChip 3.0) were used to investigate the BSL community, and uptake of radiolabeled carbon sources was used to assess the relative importance of heterotrophic vs. autotrophic production. Microbial assemblages are similar in both sites despite the strong temperature differential, supporting observations of a dynamic, convectively mixed system. Bacteria in the Actinobacteria and Aquificales phyla are abundant in the water column, and Archaea distantly related to known taxa are abundant in sediments. The functional potential appears similar across a 5-year time span, indicating a stable community with little inter-annual variation, despite the documented seasonal temperature cycle. BSL water-derived DNA contains genes for complete C, N, and S cycles, and low hybridization to probes for N and S oxidation suggests that reductive processes dominate. Many of the detected genes for these processes were from uncultivated bacteria, suggesting novel organisms are responsible for key ecosystem services. Selection imposed by low nutrients, low pH, and high temperature appear to result in low diversity and evenness of genes for key functions involved in C, N, and S cycling. Conversely, organic degradation genes appear to be functionally redundant, and the rapid assimilation of radiolabeled organic carbon into BSL cells suggests the importance of allochthonous C fueling heterotrophic production in the BSL C cycle.

Abstract
BACKGROUND Given the important role of the default mode network (DMN) in cognitive function and the well-known neurocognitive deficit in schizophrenia, it is intriguing to examine systematically the relationship between neurocognitive dysfunction and aberrant intrinsic activities, and also functional connectivity, of the DMN in patients with schizophrenia. Method First-episode, treatment-naive patients with schizophrenia (FES) (n = 115) and healthy controls (n = 113) underwent resting-state functional magnetic resonance imaging (fMRI) scans and neurocognitive tests. Intrinsic neural activities evaluated by using the fragment amplitude of low-frequency fluctuations (fALFF) and the resting-state functional connectivity assessed by seed-based correlational analysis were compared between patients and controls. Aberrant intrinsic activities and DMN connectivity in patients were then correlated to neurocognitive performance and clinical symptoms. RESULTS Compared to controls, patients with FES showed decreased fALFF in the bilateral medial prefrontal cortex (MPFC) and the orbitofrontal cortex (OFC), and increased fALFF in the bilateral putamen. Increased functional connectivity with the DMN was observed in the left insula and bilateral dorsolateral PFC (DLPFC) in patients with FES. In patients, aberrant fALFF in the bilateral OFC were correlated with cognitive processing speed; fALFF in the left OFC and right putamen were correlated with the clinical factors excited/activation and disorganization; and increased DMN functional connectivity in the left insula was correlated with the clinical factors positive, excited/activation, disorganization and neurocognitive deficit in the domain of sustained attention. CONCLUSIONS These associations between neurocognitive dysfunction and aberrant intrinsic activities, and also functional connectivity, of the DMN in patients with schizophrenia may provide important insights into the neural mechanism of the disease.

Abstract
High-mobility group box 1 (HMGB1) is a non-histone nuclear protein that is released extracellulary and has been implicated in autoimmune disease. Toll-like receptor 2 (TLR2) signalling is thought to be essential for the inflammatory response and for immune disorders. In recent studies, enhanced HMGB1 and TLR2 expressions have been found in rheumatoid arthritis (RA), respectively. The aim of this study is to explore whether HMGB1 stimulation can up-regulate the expression of TLR2 on CD14(+) monocytes from patients with RA and to clarify the subsequent events involving Th17 cells and Th17 cell-associated cytokine changes. Our results showed that the frequency of CD14(+) cells in peripheral blood mononuclear cell (PBMC) was obviously increased, and enhanced expression of TLR2 on CD14(+) monocytes was also found in patients with RA, compared with healthy controls with statistical significance (P < 0.001). In addition, the levels of IL-17, IL-23 and IL-6 in supernatants from cultured monocytes from patients and in patient's plasma were increased, and NF-κB, the downstream target of TLR2, also showed a marked elevation after monocytes were stimulated by HMGB1. This implies that the enhanced TLR2 pathway and Th17 cell polarization may be due to HMGB1 stimulation in rheumatoid arthritis.

Abstract
BACKGROUND Psoriasis is an immune disorder involving numerous cytokines. Recent studies have shown that interleukin (IL)-21 plays an important role in a variety of inflammatory and autoimmune diseases. It is highly expressed in psoriatic plaques and promotes the proliferation of epidermis in mice. It seems that IL-21 plays an important role in the pathogenesis of psoriasis. However, whether or not it is elevated in the peripheral blood of patients with psoriasis and is associated with disease severity is unclear. Therefore, our study focuses on serum IL-21 levels and their correlation with disease severity. OBJECTIVES To detect serum IL-21 levels in patients with psoriasis and investigate the correlation between these and the Psoriasis Area and Severity Index (PASI) scores. METHODS Blood samples were collected from patients with plaque psoriasis and from healthy control subjects. Serum IL-21 levels were measured by enzyme-linked immunosorbent assay in 37 patients with psoriasis and 37 healthy controls. The PASI scores of patients with psoriasis and their correlation with serum IL-21 levels were evaluated. RESULTS Serum IL-21 levels were higher in patients with psoriasis than in healthy controls (P < 0·01). Serum IL-21 levels were positively correlated with PASI scores in the patients with psoriasis (r = 0·471, P < 0·01). CONCLUSIONS Serum IL-21 levels in patients with psoriasis are elevated and positively correlate with PASI scores. These results indicate that IL-21 may play an important role in the pathogenesis of psoriasis.

Abstract
Mesenchymal stem cells (MSCs) have attracted great interest in cancer therapy owing to their tumor-oriented homing capacity and the feasibility of autologous transplantation. Currently, pancreatic cancer patients face a very poor prognosis, primarily due to the lack of therapeutic strategies with an effective degree of specificity. Anticancer gene-engineered MSCs specifically target tumor sites and can produce anticancer agents locally and constantly. This study was performed to characterize pancreas-derived MSCs and investigate the effects of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL)-engineered MSCs on pancreatic cancer cells under different culture conditions. Pancreas-derived MSCs exhibited positive expression on CD44, CD73, CD95, CD105, negative on CD34 and differentiated into adipogenic and osteogenic cells. TRAIL expression was assessed by both enzyme-linked immunosorbent assay and western blot analysis. Different patterns of TRAIL receptor expression were observed on the pancreatic cancer cell lines, including PANC1, HP62, ASPC1, TRM6 and BXPC3. Cell viability was assessed using a real-time monitoring system. Pancreatic cancer cell death was proportionally related to conditioned media from MSC(nsTRAIL) and MSC(stTRAIL). The results suggest that MSCs exhibit intrinsic inhibition of pancreatic cancer cells and that this effect can be potentiated by TRAIL-transfection on death receptor-bearing cell types.

Abstract
Laser based stereolithography methods are shown to be useful for production of gas targets for high intensity laser-plasma interaction experiments. A cylindrically symmetric nozzle with an opening of approximately 100 μm and a periodic attachment of variable periodicity are outlined in detail with associated density profile characterization. Both components are durable within the limits of relevant experiments.
