Abstract
Background Increasing evidence has indicated an association between immune infiltration in gastric cancer and clinical outcome. However, reliable prognostic signatures, based on systematic assessments of the immune landscape inferred from bulk tumour transcriptomes, have not been established. The aim was to develop an immune signature, based on the cellular composition of the immune infiltrate inferred from bulk tumour transcriptomes, to improve the prognostic predictions of gastric cancer. Methods Twenty‐two types of immune cell fraction were estimated based on large public gastric cancer cohorts from the Gene Expression Omnibus using CIBERSORT. An immunoscore based on the fraction of immune cell types was then constructed using a least absolute shrinkage and selection operator (LASSO) Cox regression model. Results Using the LASSO model, an immunoscore was established consisting of 11 types of immune cell fraction. In the training cohort (490 patients), significant differences were found between high‐ and low‐immunoscore groups in overall survival across and within subpopulations with an identical TNM stage. Multivariable analysis revealed that the immunoscore was an independent prognostic factor (hazard ratio 1·92, 95 per cent c.i. 1·54 to 2·40). The prognostic value of the immunoscore was also confirmed in the validation (210) and entire (700) cohorts. Conclusion The proposed immunoscore represents a promising signature for estimating overall survival in patients with gastric cancer. Immunoscore predicts prognosis

Abstract
The choice of the exit to egress from a facility plays a fundamental role in pedestrian modelling and simulation. Yet, empirical evidence for backing up simulation is scarce. In this contribution, we present three new groups of experiments that we conducted in different geometries. We varied parameters such as the width of the doors, the initial location and number of pedestrians which in turn affected their perception of the environment. We extracted and analysed relevant indicators such as distance to the exits and density levels. The results put in evidence the fact that pedestrians use time-dependent information to optimize their exit choice, and that, in congested states, a load balancing over the exits occurs. We propose a minimal modelling approach that covers those situations, especially the cases where the geometry does not show a symmetrical configuration. Most of the models try to achieve the load balancing by simulating the system and solving optimization problems. We show statistically and by simulation that a linear model based on the distance to the exits and the density levels around the exit can be an efficient dynamical alternative.

Abstract
Millimeter-wave imaging diagnostics, with large poloidal span and wide radial range, have been developed on the EAST tokamak for visualization of 2D electron temperature and density fluctuations. A 384 channel (24 poloidal × 16 radial) Electron Cyclotron Emission Imaging (ECEI) system in F-band (90-140 GHz) was installed on the EAST tokamak in 2012 to provide 2D electron temperature fluctuation images with high spatial and temporal resolution. A co-located Microwave Imaging Reflectometry (MIR) will be installed for imaging of density fluctuations by December 2016. This "4th generation" MIR system has eight independent frequency illumination beams in W-band (75-110 GHz) driven by fast tuning synthesizers and active multipliers. Both of these advanced millimeter-wave imaging diagnostic systems have applied the latest techniques. A novel design philosophy "general optics structure" has been employed for the design of the ECEI and MIR receiver optics with large aperture. The extended radial and poloidal coverage of ECEI on EAST is made possible by innovations in the design of front-end optics. The front-end optical structures of the two imaging diagnostics, ECEI and MIR, have been integrated into a compact system, including the ECEI receiver and MIR transmitter and receiver. Two imaging systems share the same mid-plane port for simultaneous, co-located 2D fluctuation measurements of electron density and temperature. An intelligent remote-control is utilized in the MIR electronics systems to maintain focusing at the desired radial region even with density variations by remotely tuning the probe frequencies in about 200 μs. A similar intelligent technique has also been applied on the ECEI IF system, with remote configuration of the attenuations for each channel.

Abstract
OBJECTIVE Metalloproteinases (MMPs) are key regulators of osteoarthritis (OA) and collagen degradation and have been shown to participate in endochondral ossification. The aim of this study was to determine whether microRNA-320 (miR-320) regulates the expression of MMP-13 in chondrogenesis and inflammation. EXPERIMENTAL DESIGN miR-320 expression was assessed in vitro, in the ATDC5 cell model of chondrogenesis and in interleukin-1β (IL-1β)-treated primary mouse chondrocytes (PMCs), and in vivo, in normal and OA human cartilage by in situ hybridization. ATDC5 and PMCs were transfected with miR-320 or its antisense inhibitor (anti-miR-320), respectively. The roles of activated MAP kinases (MAPK) and NF-κB were evaluated by using specific inhibitors. Direct interaction between miR-320 and its putative binding site in the 3'-untranslated region (3'-UTR) of Mmp-13 mRNA was confirmed by the luciferase reporter assay. RESULTS miR-320 expression was elevated in chondrogenic and hypertrophic ATDC5, while significantly reduced in OA cartilage compared with normal cartilage. Stimulation with IL-1β led to a significant reduction in miR-320 expression in PMCs. Upregulation of MMP-13 expression was correlated with downregulation of miR-320 expression in both PMCs and ATDC5. Overexpression of miR-320 suppressed the activity of a reporter construct containing the 3'-UTR and inhibited MMP-13 expression in both ATDC5 and IL-1β-treated PMCs, while treatment with anti-miR-320 enhanced MMP-13 expression. NF-κB and MAPK activation downregulated miR-320 expression. CONCLUSION Cartilage development and homeostasis are influenced by miR-320, which directly targets MMP-13 and regulates chondrogenesis and the IL-1β-stimulated catabolic effect in mouse chondrocytes.

Abstract
To explore the possible mechanism of the third-generation retinoic acid drugs (isotretinoin, acitretin, adapalene) in inducing skin and mucosa dryness and rhagades; specifically, mechanism by which these drugs influence keratinocyte cell culture models in vitro (HaCaT) and aquaporin channel (AQP3) protein expression was investigated. Isotretinoin, acitretin, and adapalene were applied to human keratinocyte HaCaT cells. Immunohistochemistry, reverse transcriptase polymerase chain reaction, and western blotting were used to detect their effects on AQP3 expression in HaCaT cells at different concentrations (0.000, 0.001, 0.010, 0.060, and 0.100 mg/mL) or different at times (0, 6, 12, 24, and 48 h). At 0.010 mg/mL, maximal AQP3 expression was observed in HaCaT cells; this was significantly higher than the expressions at the other concentrations (P < 0.05). After treatment with isotretinoin, acitretin, or adapalene at 0.010 mg/mL for 12 h, the expression of AQP3 was the highest in the isotretinoin group, followed by the acitretin group, with the lowest expression in the adapalene group. However, the differences were not statistically significant (P > 0.05). Retinoic acid can increase AQP3 expression in HaCaT cells, with significant effects observed with 0.010 mg/mL isotretinoin treatment for 12 h. The side effects, namely skin and mucosa dryness caused by retinoic acid might be related to its effects on AQP3 expression.

Abstract
The protective effect of a polysaccharide from Dictyophora indusiata(DP1)against oxidative hemolysis was comprehensively evaluated. The 2, 2-azobis (2-amidino-propane) dihydrochloride (AAPH)-induced erythrocyte hemolysis assay showed that DP1 exhibited excellent anti-hemolytic activity(87.4% hemolysis suppression ratio at 20 nmol/mL). Also, the formation of conjugated diene induced by cupric chloride (CuCl2) in plasma was significantly inhibited by DP1. Besides, DP1 could effectively inhibit AAPH-induced overproduction of reactive oxygen species (81.5% inhibition at 20 nmol/mL) and alleviated the enhancement of intracellular antioxidant enzymes including superoxide dismutase(SOD), glutathione peroxidase (GPX) and catalase (CAT) activities. Also, the malondialdehyde (MDA) formation caused by oxidative stress was suppressed by 57.0% at DP1 concentration of 20 nmol/mL. Taken together, the possible intracellular antioxidant detoxifying mechanism of DP1 was probably via preserving the activities of the antioxidant enzymes (SOD, GPx and CAT) as well as inhibiting lipid peroxidation, and thus alleviated erythrocytes oxidation and plasma oxidation.

Abstract
BACKGROUND Tinea capitis is very common in Western China, with the most widespread aetiological agent being Trichophyton violaceum, while Microsporum canis is prevalent in the remainder of China. Conventional diagnostics and internal transcribed spacer (ITS) sequencing analyses have proven relatively limited due to the close phylogenetic relationship of anthropophilic dermatophytes. Therefore, alternative molecular tools with sufficient specificity, reproducibility and sensitivity are necessary. OBJECTIVES To evaluate two molecular techniques [multiplex ligation-dependent probe amplification (MLPA) and rolling circle amplification (RCA)] for rapid detection of the aetiological agents of tinea capitis, T. violaceum and M. canis. METHODS Probes of RCA and MLPA were designed with target sequences in the rDNA ITS gene region. Strains tested consist of 31 T. violaceum, 22 M. canis and 24 reference strains of species that are taxonomically close to the target species. RESULTS The specificity and reproducibility of RCA and MLPA in detection of T. violaceum and M. canis were both 100% in both species. Sensitivity testing showed that RCA was positive at concentrations down to 1·68 × 10(6) copies of DNA in the TvioRCA probe, and 2·7 × 10(8) copies of DNA in McRCA. MLPA yielded positive results at concentrations of DNA down to 1·68 × 10(1) copies in the TvioMLPA probe and 2·7 × 10(2) in McMLPA. CONCLUSIONS The two techniques were sufficiently specific and sensitive for discriminating the target DNA of T. violaceum and M. canis from that of closely related dermatophytes. RCA and MLPA are advantageous in their reliability and ease of operation compared with standard polymerase chain reaction and conventional methods.

Abstract
The development of advanced molecular technologies has ushered in the era of 'omics' science, including transcriptomics, proteomics, and genomics. Genomics, or whole genome approach, has become the most comprehensive investigative method to identify new gene mutations, signal pathways and drug targets for cancers. The purpose of this review is to summarize current second generation sequencing techniques in applied genomics, and to analyze the advantages and/or problems associated with each of the various sequencing platforms. Our understanding of molecular factors associated with tumorigenesis is no longer limited to the mutation of well—known cancer related genes, but may involve a broader range of factors involved in tumor development, including novel somatic mutations, gene fusions, long non—coding RNAs, microRNAs, copy number variations, methylation, and genomic structural variations. Furthermore, these new methods are not limited to analyses of single genetic or epigenetic factor, but offer comprehensive molecule profiling as a more critical and powerful approach to decoding the mystery of tumor development and identifying more reliable cancer biomarkers.

Abstract
AIM This study aims to explore the risk factors associated with autonomic dysreflexia (AD) reflex during cystolitholapaxy and increase the awareness of urologists on the dangerous reaction of AD in patients with spinal cord injury (SCI). METHODS Data of 89 SCI patients with bladder stone who underwent cystolitholapaxy were retrospectively analyzed. Patients were divided into two groups according to the presence or absence of AD. Risk factors may associated with AD during the endoscopic procedure were analyzed by comparing clinical and operative features between the two groups. RESULTS Of the 89 patients, 31 (34.83%) developed AD during the procedure. The patients who developed AD had larger stones (4.58±1.26 cm vs. 3.75±1.15 cm, P<0.01), more stones (2.29±0.86 vs. 1.74±0.81, P<0.01), and greater injury (83.87% vs. 41.38%, above T6, P<0.01) than those who did not develop AD. The patients who developed AD suffered higher irrigation (83.55± 13.05 cm vs. 77.47±10.91 cm, P<0.05) and longer operation time (60.65±17.78 min vs. 49.31±14.31 min, P<0.01) than those who did not develop AD. The AD group also received local anesthetics to a larger extent compared with non-AD group, which more often had spinal anesthesia. CONCLUSION The patients who developed AD during the procedure had larger stones, more stone number, injury level more often above T6, higher hydraulic irrigation height, and longer operation time compared with the patients who did not develop AD. Urologists should pay extra care when performing cystolitholapaxy on individuals with these features.

Abstract
BACKGROUND AND PURPOSE Corticothalamic networks are considered core pathologic substrates for idiopathic generalized epilepsy; however, the predominant epileptogenic epicenters within these networks are still largely unknown. The current study aims to identify these epicenters by resting-state functional connectivity. MATERIALS AND METHODS To identify epicenters within the corticothalamic networks in idiopathic generalized epilepsy, we retrospectively studied a large cohort of patients with this condition (n = 97) along with healthy controls (n = 123) by resting-state functional MR imaging. The thalamus was functionally divided into subregions corresponding to distinct cortical lobes for 5 parallel corticothalamic networks. The functional connectivity between each voxel in the cortical lobe and the corresponding thalamic subregion was calculated, and functional connectivity strength was used to evaluate the interconnectivity of voxels in the cortex and thalamus. RESULTS The projection of 5 cortical lobes to the thalamus is consistent with previous histologic findings in humans. Compared with controls, patients with idiopathic generalized epilepsy showed increased functional connectivity strength in 4 corticothalamic networks: 1) the supplementary motor area, pulvinar, and ventral anterior nucleus in the prefrontal-thalamic network; 2) the premotor cortex and ventrolateral nucleus in motor/premotor-thalamic networks; 3) the visual cortex, posterior default mode regions, and pulvinar in parietal/occipital-thalamic networks; and 4) the middle temporal gyrus in the temporal-thalamic network. CONCLUSIONS Several key nodes were distinguished in 4 corticothalamic networks. The identification of these epicenters refines the corticothalamic network theory and provides insight into the pathophysiology of idiopathic generalized epilepsy.

Abstract
BACKGROUND Psoriasis patients have relatively infrequent cutaneous viral infections compared to atopic dermatitis patients. Increased expression of four antiviral proteins (MX1, BST2, ISG15 and OAS2) has been reported in psoriatic skin and genetic studies of psoriasis have identified susceptibility genes in antiviral pathways. OBJECTIVE To determine if psoriasis is associated with pervasive expression of antiviral genes in skin and blood. METHODS We performed RNA sequencing on skin samples of 18 subjects with chronic plaque psoriasis and 16 healthy controls. We examined the expression of a predefined set of 42 antiviral genes, each of which has been shown in previous studies to inhibit viral replication. In parallel, we examined antiviral gene expression in atopic dermatitis, non-lesional psoriatic skin and psoriatic blood. We performed HIV-1 infectivity assays in CD4+ peripheral blood T cells from psoriatic and healthy individuals. RESULTS We observed significant overexpression of 16 antiviral genes in lesional psoriatic skin, with a greater than two-fold increase in ISG15, RSAD2, IRF7, MX2 and TRIM22 (P < 1E-07). None of these genes was overexpressed in atopic dermatitis skin (P < 0.0001) or non-lesional psoriatic skin. In contrast to the skin compartment, no differences in antiviral gene expression were detected in the peripheral blood of psoriasis cases compared to healthy controls. CD4+ T cells from both psoriatic and healthy patients supported HIV-1 infection at a similar rate. CONCLUSION Our findings highlight psoriasis as an inflammatory disease with cutaneous but not systemic immune activation against viral pathogens.

Abstract
OBJECTIVES Trichophyton violaceum is an anthropophilic dermatophyte that is endemic to parts of Africa and Asia and is sporadic in Europe. T. violaceum mainly causes tinea capitis in both children and adolescents. Although the infections caused by T. violaceum are of considerable medical importance, its antifungal susceptibility profile remains poorly examined. METHODS In this study, we tested the in vitro antifungal susceptibility of a set of clinical T. violaceum isolates obtained from tinea capitis patients, using the CLSI broth microdilution method. We tested eight antifungals and used isolates collected from Western China (21), Eastern China (12), the Middle East (1), Europe (20), South Africa (7) and Canada (1). RESULTS The geometric means of the MICs of the antifungals for all isolates were as follows (in increasing order): posaconazole, 0.021 mg/L; terbinafine, 0.023 mg/L; voriconazole, 0.062 mg/L; amphotericin B, 0.20 mg/L; itraconazole, 0.34 mg/L; caspofungin, 0.56 mg/L; fluconazole, 4.23 mg/L; and flucytosine, 8.46 mg/L. No statistically significant differences in the susceptibility profiles of T. violaceum were detected within the geographical regions tested. CONCLUSIONS Posaconazole, terbinafine and voriconazole were shown to be the most potent antifungal agents against T. violaceum isolates obtained from tinea capitis patients worldwide. These results might help clinicians in developing appropriate therapies that have a high probability of successfully treating tinea capitis due to T. violaceum.

Abstract
BACKGROUND AND PURPOSE Voxel-mirrored intrinsic functional connectivity allows the depiction of interhemispheric homotopic connections in the human brain, whereas time-shift intrinsic functional connectivity allows the detection of the extent of brain injury by measuring hemodynamic properties. We combined time-shift voxel-mirrored homotopic connectivity analyses to investigate the alterations in homotopic connectivity in mesial temporal lobe epilepsy and assessed the value of applying this approach to epilepsy lateralization and the prediction of surgical outcomes in mesial temporal lobe epilepsy. MATERIALS AND METHODS Resting-state functional MR imaging data were acquired from patients with unilateral mesial temporal lobe epilepsy (n=62) (31 left- and 31 right-side) and healthy controls (n=33). Dynamic interhemispheric homotopic architecture seeding from each hemisphere was individually calculated by 0, 1, 2, and 3 repetition time time-shift voxel-mirrored homotopic connectivity. Voxel-mirrored homotopic connectivity maps were compared between the patient and control groups by using 1-way ANOVA for each time-shift condition, separately. Group comparisons were further performed on the laterality of voxel-mirrored homotopic connectivity in each time-shift condition. Finally, we correlated the interhemispheric homotopic connection to the surgical outcomes in a portion of the patients (n=20). RESULTS The patients with mesial temporal lobe epilepsy showed decreased homotopic connectivity in the mesial temporal structures, temporal pole, and striatum. Alterations of the bihemispheric homotopic connectivity were lateralized along with delays in the time-shift in mesial temporal lobe epilepsy. The patients with unsuccessful surgical outcomes presented larger interhemispheric voxel-mirrored homotopic connectivity differences. CONCLUSIONS This study showed whole patterns of dynamic alterations of interhemispheric homotopic connectivity in mesial temporal lobe epilepsy, extending the knowledge of abnormalities in interhemispheric connectivity in this condition. Time-shift voxel-mirrored homotopic connectivity has the potential for lateralization of unilateral mesial temporal lobe epilepsy and may have the capability of predicting surgical outcomes in this condition.

Abstract
OBJECTIVE Joint trauma can lead to a spectrum of acute lesions, including cartilage degradation, ligament or meniscus tears, and synovitis, all potentially associated with osteoarthritis (OA). This study was undertaken to generate and validate a murine model of knee joint trauma following noninvasive controlled injurious compression in vivo. METHODS The right knees of 8-week-old mice were placed in a hyperflexed position and subjected to compressive joint loading at 1 of 3 peak forces (3N, 6N, or 9N) for 60 cycles in a single loading period and harvested on days 5, 9, and 14 after loading (n = 3-5 for each time point and for each loading). The left knees were not loaded and were used as the contralateral control. Histologic, immunohistochemical, and enzyme-linked immunosorbent assay analyses were performed to evaluate acute pathologic features in chondrocyte viability, cartilage matrix metabolism, synovial reaction, and serum cartilage oligomeric matrix protein (COMP) levels. RESULTS Acute joint pathology was associated with increased injurious loads. All loading regimens induced chondrocyte apoptosis, cartilage matrix degradation, disruption of cartilage collagen fibril arrangement, and increased levels of serum COMP. We also observed that 6N loading induced mild synovitis by day 5, whereas at 9N, with tearing of the anterior cruciate ligament, severe posttraumatic synovitis and ectopic cartilage formation were observed. CONCLUSION We have established a murine model of knee joint trauma with different degrees of overloading in vivo. Our results suggest that immediate therapies particularly targeted to apoptosis and synovial cell proliferation could affect the acute posttraumatic reaction to potentially limit chronic consequences and OA.

Abstract
The previous studies in this lab discovered that microRNA-885-3p (miR-885-3p) was regulated by a sulfated polysaccharide that bound to bone morphogenetic protein receptor, type IA (BMPR1A) to inhibit angiogenesis. However, its specific role and its mechanism of action in tumor cells have not been elucidated. We show that miR-885-3p markedly suppresses angiogenesis in vitro and in vivo. MiR-885-3p inhibits Smad1/5/8 phosphorylation and downregulates DNA-binding protein inhibitor ID-1 (Id1), a proangiogenic factor, by targeting BMPR1A, leading to impaired angiogenesis. Overexpression or silencing of BMPR1A affects angiogenesis in a Smad/Id1-dependent manner. We further show that miR-885-3p impairs the growth of HT-29 colon cancer cell xenografts in nude mice by suppressing angiogenesis through disruption of BMPR1A and Smad/Id1 signaling. These results support a novel role for miR-885-3p in tumor angiogenesis by targeting BMPR1A, which regulates a proangiogenic factor, and provide new evidence that targeting miRNAs might be an effective therapeutic strategy for improving colon cancer treatment.

Abstract
Background: Genome-wide association studies (GWAS) have identified over 100 germline variants that influence susceptibility to multiple sclerosis, most of which map within or near to genes with immunological function. However, the role of somatic mutations in multiple sclerosis has not been investigated. Objective: The objective of this paper is to explore the role that somatic mutations might play in the development of multiple sclerosis. Methods: We exome-sequenced in total 21 individual CD4+ lymphocytes isolated from cerebrospinal fluid of two patients. In addition we sequenced DNA from the patients’ peripheral blood to serve as germline reference. Results: In comparison with the respective germline sequence, each cell differed at an average of 1784 positions, but as anticipated subsequent analysis confirms that most, if not all, of these potential mutations are likely to represent artefacts generated during the amplification of a single genome and/or by sequencing. Fifty-six of the potential mutations were predicted to have likely functional effects on genes that have previously been implicated by GWAS, including three in the CD6 gene. Conclusion: More robust methods applied to larger numbers of cells will be needed to define the role of somatic mutations.

Abstract
BACKGROUND Postoperative respiratory complications often arise in lung cancer patients after lung resection, although these are often difficult to predict. We sought to identify reliable predictors of early-onset postoperative respiratory complications in lung cancer patients who had moderate-to-severe preoperative respiratory impairment. METHODS This was a prospective observational study that included 107 consecutive lung cancer patients with forced expiratory volume in 1 s <60% of predicted who were scheduled for thoracotomy and lung resection. Preoperative functional assessments included pulmonary function testing by spirometry, single breath diffusion capacity of lung for carbon monoxide, and cardiopulmonary exercise testing. Risk factors for early-onset postoperative respiratory complications that occurred within 30 days postoperatively were sought from among these pulmonary function testing and cardiopulmonary exercise testing results. RESULTS By multivariable logistic regression, peak oxygen uptake (V'O2max%; p < 0.001) and the transcutaneous pulse oxygen saturation difference during load exercise (ΔSPO2%; p < 0.001) were independent predictors of postoperative respiratory complications. A receiver operating characteristic curve had an area under the curve of 0.846 for the combination of V'O2max% and ΔSPO2%, while the area under the curve with V'O2max% only was 0.726. From this, the probability of postoperative respiratory complications was [Formula: see text]. Pcomplication ≥ 0.202 for postoperative respiratory complications had a sensitivity of 80.8% and a specificity of 81.5%. CONCLUSIONS For lung cancer patients with forced expiratory volume in 1 s <60% of predicted, in addition to common preoperative tests, V'O2max% and ΔSPO2% may be an aid for predicting early-onset postoperative respiratory complications.

Abstract
BACKGROUND Congenital or acquired abnormalities may cause an ureteral injury or defect. The main methods to reconstruct a long ureter often cause serious complications. In this study, we sought to construct a tissue-engineered graft by seeding bone marrow mesenchymal stem cells (MSCs) and smooth muscle cells (SMCs) into a bladder acellular matrix (BAM) for ureteral reconstruction. METHODS Isolated, proliferated, and in vitro identified rabbit bone marrow MSCs and SMCs were seeded into BAM as the experimental group. Grafts only seeding SMCs were the control group. Cell-seeded grafts were used to construct tissue-engineered tubular grafts (TETG) for transplantation into the rabbit's omentum for 2 weeks before ureteral reconstruction. Evolutionary histology was performed at 2, 4, 8, and 16 weeks postoperatively. Renal function and ureteral obstruction were evaluated using intravenous urography at 16 weeks. RESULTS Flow cytometry demonstrated bone marrow MSCs to express CD29, CD44, CD90, but not CD34. Histological examination revealed consistent regeneration of TETG urothelium in the experimental group. At 8 and 16 weeks after TETG grafting in vivo, multilayer urothelium covered the entire lumen with visible neovascularization within the center. Organized smooth muscle bundles were observed. Intravenous urography demonstrated no ureteral stricture or hydronephrosis. The 5 rabbits were dead within 4 weeks postoperatively. Autopsy showed scar formation inside the graft with severe hydronephrosis. CONCLUSION We successfully constructed a TETG by seeding bone marrow MSCs and SMCs into BAM for ureteral reconstruction. Thus bone marrow MSCs can potentially promote urothelial regeneration to achieve a tissue-engineered ureter.

Abstract
OBJECTIVE Castleman's disease (CD) is a rare disorder of unknown aetiology characterized by lymph node enlargement. This study evaluated the clinical features, diagnosis and outcomes of surgical treatment in patients with CD. METHODS The medical records of 10 patients with histologically confirmed CD who underwent surgery between 2003 and 2008 were retrospectively reviewed. Study endpoints were survival and recurrence. RESULTS The age of disease onset ranged from 11 to 63 years (median 38 years). Of the 10 patients included in the study, eight were diagnosed with localized (unicentric) CD and two with multicentric CD. All eight patients with localized (unicentric) CD were asymptomatic. Histological evidence indicated the hyaline vascular form of CD in eight patients and the plasmacytic form in the remaining two patients. The primary treatment was complete surgical resection in nine cases, and these patients were alive with no evidence of recurrence or exacerbation at the time of writing (June 2011). CONCLUSIONS Localized (unicentric) CD is usually of the hyaline vascular form and complete surgical excision of the tumour allows full recovery in most cases.

Abstract
OBJECTIVES MicroRNAs (miRNAs) play an important role in the regulation of chondrogenesis of mesenchymal stem cells, but their expression still remains unknown in human adipose-derived stem cells (hADSCs). In this study the miRNA expression profile during chondrogenic differentiation of hADSC and the potential mechanism whereby miRNAs may affect the process of chondrogenesis are considered. METHODS hADSCs were isolated and cultured. The expression of chondrogenic proteins was detected using enzyme-linked immunosorbent assay (ELISA). miRNA expression profiles before and after chondrogenic induction were obtained using miRNA microarray essay and differently expressed miRNAs were primarily verified using quantitative real-time polymerase chain reaction (qRT-PCR). Putative targets of the miRNAs were predicted using online software programs MiRanda, TargetScan and miRBase. RESULTS Twelve miRNAs were found to be differentially expressed pre- and post-chondrogenic induction by over a two-fold change, including eight up-regulated miRNAs (miR-193b, miR-199a-3p/hsa-miR-199b-3p, miR-455-3p, miR-210, miR-381, miR-92a, miR-320c, and miR-136), and four down-regulated miRNAs (miR-490-5p, miR-4287, miR-BART8*, and miR-US25-1*). qRT-PCR analysis further confirmed these results. Predicted target genes of the differentially expressed miRNAs were based on the overlap of at least two online prediction algorithms, with the known functions of regulating chondrogenic differentiation, self-renewal, signal transduction and cell cycle control. CONCLUSIONS In this study we have identified a group of miRNAs and their target genes, which may play important roles in regulating chondrogenic differentiation of hADSCs. Our results provide the basis for further investigation into the molecular mechanism of chondrogenesis in hADSCs and their differentiation for cartilage engineering.

Abstract
Phototherapy is a mainstay of vitiligo treatment and has varying rates of efficacy. Narrowband ultraviolet (UV) B (NB-UVB) and UVA have been used for decades, but it is only recently that monochromatic excimer light (MEL) was developed for use in dermatology and adapted for the treatment of vitiligo. The specific 308-nm radiation wavelength is delivered in a targeted form by the xenon-chloride excimer laser and is also available in an incoherent form that is commonly referred to as the excimer lamp. MEL administered by both laser and lamp has shown efficacy superior to NB-UVB for the treatment of vitiligo and induces more changes at the cellular level than conventional UVB modalities. The excimer laser is effective in adults and children with vitiligo in all skin types as monotherapy or in combination with other established vitiligo therapeutics. Treatment regimens studied included excimer laser two to three times weekly for up to 36 weeks. Patients commonly achieved > 75% repigmentation. The laser has also been used in combination with topical corticosteroids, calcineurin inhibitors and vitamin D analogues, as well as surgery, thus further expanding treatment options for patients with vitiligo. The excimer lamp has been used for treatments one to three times a week for up to 24 weeks and was found to be equal to excimer laser in a head-to-head comparison. It has also been used in combination with topical corticosteroids and oral vitamin E. Both MEL modalities have a limited adverse side-effect profile. Long-term effects are yet to be determined; however, based on available data on UVB phototherapy as well as the properties of MEL devices, there is probably only a minimal increased malignancy risk.

Abstract
OBJECTIVE: This prospective randomized study evaluated the efficacy and patient tolerance of dexmedetomidine compared with midazolam for sedation in postoperative patients undergoing flexible bronchoscopy. METHODS: A total of 198 postoperative patients were randomized to receive dexmedetomidine ( n = 99) or midazolam ( n = 99) to produce conscious sedation for bronchoscopy. Peripheral oxygen saturation, heart rate and systolic and diastolic arterial pressures were recorded before, during and after the procedure. Patient tolerance was recorded using various visual analogue scales. RESULTS: The mean lowest peripheral oxygen saturation was significantly lower in the midazolam group than in the dexmedetomidine group. Heart rate and systolic arterial pressure were both significantly higher during bronchoscopy in the midazolam group than in the dexmedetomidine group. Bronchoscopy was well tolerated in both groups; there was no between-group difference in patient discomfort scores or in the percentage of patients who would accept repeat bronchoscopy. CONCLUSIONS: Compared with midazolam, dexmedetomidine provided better oxygen saturation and was equally well tolerated for conscious sedation in postoperative patients undergoing bronchoscopy.

Abstract
The Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation was introduced to estimate glomerular filtration rate (GFR) in chronic kidney disease (CKD) patients based on serum creatinine. The CKD-EPI equation shows better accuracy compared with the current gold standard equation, the Modification of Diet in Renal Disease (MDRD) equation, but it has not been externally validated in Chinese patients. This study compared the CKD-EPI equation with the original MDRD equation and two Chinese MDRD-based equations for estimating GFR in 200 Chinese CKD patients. The (99m)Tc-diethylenetriamine penta-acetate ((99m)Tc-DTPA) method was used to determine actual GFR. The CKD-EPI equation produced GFR estimates that were more consistent with the (99m)Tc-DTPA GFR than did the MDRD equations. The precision and accuracy of the CKD-EPI equation were significantly higher than those of the MDRD equations. In conclusion, the CKD-EPI equation was superior to the existing MDRD equations in terms of estimating GFR and we recommend its clinical use in Chinese CKD patients.

Abstract
BACKGROUND Proliferation of activated CD4+ T lymphocytes is inhibited by indoleamine 2,3-dioxygenase (IDO). OBJECTIVE We undertook the present study to test the hypothesis that IDO-expressing immature DCs (imDCs) can restore immune tolerance in mice suffering from allergic airway inflammation. METHODS imDCs were generated from murine bone marrow cells using granulocyte-macrophage colony-stimulating factor.The imDCs were subsequently transfected with an IDO expression vector (pEGFP-N1-IDO). Surface marker expression, including CD11c, MHCII, CD80, and CD86, was analyzed using flow cytometry. IDO-expressing imDCs were injected into the trachea of ovalbumin (OVA)-sensitized mice, and lung histopathology and cytokine expression in bronchoalveolar lavage fluid were assessed. The splenic CD4+ T cells of OVA-sensitized mice were isolated and co-cultured with pEGFP-N1-IDO-expressing imDCs, and apoptosis of CD4+ T cells was detected using the terminal deoxynucleotidyl transferase dUTP nick end labeling assay. RESULTS Expression of IDO in imDCs did not alter cell surface molecule expression. We observed marked lung inflammation, elevated total cell and eosinophil count, and altered cytokine levels in OVA-sensitized mice. These parameters improved upon inoculation with IDO-expressing imDCs. Co-culture with IDO-expressing imDCs also induced apoptosis, inhibited IL-4 and IL-5 expression, and upregulated IFN-gamma expression in CD4+ T cells. CONCLUSIONS IDO-expressing imDCs induced T(H)2 cell apoptosis and reduced T(H)2 cell activation and allergic airway inflammation in OVA-sensitized mice. Thus, upregulation of IDO expression may provide a novel immunointervention strategy for asthma treatment.
