Abstract
BACKGROUND Auditory verbal hallucinations (AVHs) are one of the most common and severe symptoms of schizophrenia, but the neuroanatomical abnormalities underlying AVHs are not well understood. The present study aims to investigate whether AVHs are associated with cortical thinning. METHODS Participants were schizophrenia patients from four centers across China, 115 with AVHs and 93 without AVHs, as well as 261 healthy controls. All received 3 T T1-weighted brain scans, and whole brain vertex-wise cortical thickness was compared across groups. Correlations between AVH severity and cortical thickness were also determined. RESULTS The left middle part of the middle temporal gyrus (MTG) was significantly thinner in schizophrenia patients with AVHs than in patients without AVHs and healthy controls. Inferences were made using a false discovery rate approach with a threshold at p < 0.05. Left MTG thickness did not differ between patients without AVHs and controls. These results were replicated by a meta-analysis showing them to be consistent across the four centers. Cortical thickness of the left MTG was also found to be inversely correlated with hallucination severity across all schizophrenia patients. CONCLUSION The results of this multi-center study suggest that an abnormally thin left MTG could be involved in the pathogenesis of AVHs in schizophrenia.

Abstract
SOX2 overlapping transcript (Sox2ot), a long noncoding RNA (lncRNA), was initially found a close concomitant expression pattern of SOX2 gene. Multiple studies have demonstrated that the relatively upregulated Sox2ot could be observed in different types of cancer tissues and effectively promotes cell proliferation, invasion, and tumorigenesis in vitro. In the present study, we aimed to detect the crucial prognostic role of Sox2ot in cholangiocarcinoma (CCA) patients' clinicopathologic features and evaluated the correlation between Sox2ot expression and CCA patients overall survival. 58 CCA patients who underwent surgical treatment were recruited for the investigation. Sox2ot expression levels estimated by the quantitative real-time PCR (qRT-PCR) showed that both clinical tissues and cell lines possessed the overexpressed states and the upregulation of Sox2ot significantly associated with lymph node invasion (p=0.0308), TNM stage (p=0.0072) and postoperative recurrence (p=0.0019). The Kaplan-Meier curve showed a strong association between Sox2ot and overall survival (OS) and multivariate analysis confirmed this finding. Furthermore, the proliferation, migration and invasion assays were carried out with RBE and QBC939 cell lines and the knockdown of Sox2ot in all experiments could remarkably decrease malignant biological behaviors. Taken together, lncRNA Sox2ot indicates an unfavorable prognostic biomarker and potential therapeutics target for CCA patients.

Abstract
Long non-coding RNAs (lncRNAs) recently emerge as a novel class of non-coding RNAs (ncRNAs) with larger than 200 nucleotides in length. Due to lack an obvious open reading frame, lncRNAs have no or limited protein-coding potential. To date, accumulating evidence indicates the vital regulatory function of lncRNAs in pathological processes of human diseases, especially in carcinogenesis and development. Deregulation of lncRNAs not only alters cellular biological behavior, such as proliferation, migration and invasion, but also represents the poor clinical outcomes. Zinc finger E-box binding homeobox 1 antisense 1 (ZEB1-AS1), an outstanding cancer-related lncRNA, is identified as an oncogenic regulator in diverse malignancies. Dysregulation of ZEB1-AS1 has been demonstrated to exhibit a pivotal role in tumorigenesis and progression, suggesting its potential clinical value as a promising biomarker or therapeutic target for cancers. In this review, we make a summary on the current findings regarding the biological functions, underlying mechanisms and clinical significance of ZEB1-AS1 in cancer progression.

Abstract
Objective: To analyze the spatial clustering characteristics of HIV/AIDS among men who have sex with men (MSM) in Chongqing from January 2004 to December 2015 and understand the HIV/AIDS related behaviors among MSM by interview. Methods: Data related to MSM who were infected with HIV and whose present address were in Chongqing, were collected from Information System on the HIV/AIDS Prevention and Control. Information included the age when the information was inputted, address, occupation, education level, and marital status. The total number of MSM who were infected with HIV and reported was 6 604 in Chongqing. Those with unknown address were ruled out. The spatial autocorrelation analysis and the local spatial autocorrelation analysis were carried out by using ArcGIS 10.3. In addition, in November 2015 and May 2016, using a convenience sampling, we conducted one-on-one interviews among 23 MSM in the Chongqing Center for Disease Control and prevention. INCLUSION CRITERIA Receiving voluntary counseling and testing in the urban area of Chongqing and willing to participate in the interview by oral informed consent; male and self-described as MSM. The content of the interview included basic information, sexual orientation, sexual role, the main place of making friends, the main place of sexual behavior, a long-term experience in other provinces and drug abuse. Results: The HIV/AIDS reported number in Chongqing from 2004 to 2015 showed an uptrend, except in 2010. The age distribution of 6 604 cases of HIV positive patients was mainly concentrated in the 15-34 years old, about 68.5% (4 522 cases). There was a positive spatial autocorrelation in MSM, except 2005 (Moran's I=-0.046, P=0.823), form 2004 to 2015, Global Moran's I values were 0.308, 0.254, 0.335, 0.683, 0.673, 0.558, 0.620, 0.673, 0.685, 0.654 and 0.649, respectively; all P values were <0.01. The result of local spatial autocorrelation analysis showed that high-high accumulation area development in Chongqing city was divided into two stages in 2004-2015, which were Yuzhong, Jiangbei, and Shapingba district in 2004-2007 and the expanded Jiulongpo, Nan'an, and Yubei district in 2008-2015. Qualitative interviews results revealed that the age of the respondents was 20-44, and the mainly way of making friends were using mobile phone App and internet (17 participants). Most of the participants (11 participants) were making friends in the bar. The majority of respondents would ask the friends or themselves to use condoms when meeting with them the first time (19 participants), and 8 of respondents reported that they would not use condoms when their old friends refused to use condoms. Conclusion: The HIV infected MSM mainly aged between 15-34 years old and the spatial distribution of HIV/AIDS among MSM was clustered in economically developed main area in Chongqing. MSM began to make friends on the Internet, and could not adhere to using condom, which indicated that we should focus on internet intervention to find more efficacious interventions.

Abstract
A growing number of central pancreatectomies are performed. However, reconstruction of pancreaticoenteral digestive continuity after central pancreatectomy remains debated. This study evaluates the short-term outcomes of binding pancreaticogastrostomy anastomosis in central pancreatectomy.We have reviewed our experience with 52 patients who underwent binding pancreaticogastrostomy following central pancreatectomy from February 2009 to March 2015. Indication includes 6 noninvasive intraductal papillary mucinous neoplasms, 11 neuroendocrine tumors, 12 solid pseudopapillary tumor, 9 serous cystadenoma, 6 mucinous cystadenoma, and 8 focal pancreatic traumas.The mortality rate was nil while the morbidity rate was 34.6%. Eighteen patients experienced complications including 6 pancreatic fistulas, 2 postpancreatectomy hemorrhages, 4 delayed gastric emptying, 1 hypostatic pneumonia, and 5 pancreatitis. The median postoperative length of hospital stay was 12 days (10 days for patients without fistula). None of the 52 patients were found to have pancreatic endocrine or exocrine insufficiency or recurrence of tumors.Central pancreatectomy with binding pancreaticogastrostomy is a useful and practicable surgical procedure for benign or borderline lesions of the pancreatic neck or proximal body.

Abstract
The incidence of extrahepatic cholangiocarcinoma (ECC) is the highest of all the cholangiocarcinoma cases. However, the molecular mechanism of ECC genesis and progression remains unclear. Long non-coding RNAs (lncRNAs) have been revealed to perform critical regulatory roles in cancer biology. In order to understand lncRNA expression patterns and their potential function in ECC, a transcriptome analysis of lncRNA and mRNA expression was performed in ECC and paired adjacent non-cancerous tissues using Agilent human lncRNA + mRNA arrayV4.0 (4×180 K format). It was identified that 268 lncRNAs and 459 mRNAs were differentially expressed in ECC. Among these, 78 lncRNAs and 66 mRNAs were upregulated >2-fold compared with adjacent non-cancerous tissues, and 190 lncRNAs and 393 mRNAs were downregulated in the ECC samples. Differences in lncRNA expression between ECC and paired adjacent non-cancerous tissues were confirmed using reverse transcription-quantitative polymerase chain reactionas proof of principle. Functional analysis of co-expressed mRNAs with lncRNAs indicated that these dysregulated lncRNAsmay be involved in known ECC-associated biological processes and pathways. The present findings indicated that mRNAs and lncRNAs perform important roles in the development and progression of ECC. The present findings may lay the foundation for future efforts to understand the role of lncRNAs and develop novel biomarkers in ECC.

Abstract
BACKGROUND Psoriasis is a complex disease influenced by both genetic and environmental factors with abnormal gene expression in lesional skin. However, no studies are available on genome-scale gene expression of psoriatic lesions in the Chinese population. In addition, systematic studies on the biological pathways, pathogenicity and interaction networks of psoriasis-related genes with abnormal expression profiles require further investigation. OBJECTIVES To further explore the associated pathways in psoriasis by functional analysis and to identify the key genes by gene pathogenicity analysis. METHODS We performed RNA sequencing on 60 skin biopsy samples from patients with psoriasis and healthy controls to identify the primary differentially expressed genes in psoriatic lesional skin. We retrieved all reported psoriasis-associated genes and performed integrative analyses covering gene expression profiling, pathway analysis, gene pathogenicities and protein-protein interaction networks. RESULTS We found that internal and external stimuli may activate immunoinflammatory responses to promote the development of psoriasis. Pathways associated with infectious diseases and cancers were identified by functional and pathway analyses. The gene pathogenicity analysis revealed five key genes in psoriasis: PPARD, GATA3, TIMP3, WNT5A and PTTG1. CONCLUSIONS Our analyses showed that genes contributed to the pathogenesis of psoriasis by activating risk pathways with components abnormality in expression. We identified five potentially pathogenic genes for psoriasis that may serve as important biomarkers for the diagnosis and treatment.

Abstract
BACKGROUND This study aimed to investigate the expression and localisation of fol-licle stimulating hormone receptor/growth hormone receptor/luteinising hormone receptor (FSHR/GHR/LHR) in different tissues and examine the regulatory effects of FSHR/GHR/LHR in the reproductive organs of female yaks during luteal phase. MATERIALS AND METHODS The quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry assays were utilised to analyse the expression and localisation of FSHR/GHR/LHR in different tissues on female yaks. RESULTS The qRT-PCR results showed that the mRNA expressions of FSHR/GHR/ /LHR were significantly different in the non-reproductive organs (p < 0.01); the highest expression level was observed in the kidney, cerebellum and lung, whereas the lower expression level was observed in the liver and spleen. Im-munohistochemistry assay results showed that FSHR/GHR/LHR were located in kidney tubules, Purkinje cells, cerebellar medulla, alveolar cells and hepato-cytes. In addition, the expression levels of FSHR and GHR were considerably higher than LHR in the reproductive organs of female yaks during luteal phase (p < 0.01). FSHR/GHR/LHR were located in cardiac muscle cells, cerebellar medulla, and theca cell lining of reproductive organs. Furthermore, the expression level of FSHR was higher than those of GHR and LHR in all examined tissues. CONCLUSIONS Therefore, the expression and localisation of FSHR/GHR/LHR possibly helped to evaluate the effects of them in tissue specific expression on female yaks, investigate the function and mechanism of FSHR/GHR/LHR in the reproductive organs of female yaks during luteal phase.

Abstract
Long non-coding RNAs (lncRNAs) have been documented to play key roles in a wide range of pathophysiological processes, including cancer initiation and progression. Recently, the aberrant expression of urothelial carcinoma associated 1 (UCA1) was observed in many types of cancers. However, its clinical relevance and exact effects in cholangiocarcinoma (CCA) remains unknown. In the present study, we aimed to investigate the clinical significance of UCA1 and evaluate its prognostic value in patients with CCA. Besides, the functional roles of UCA1 were detected both in vitro and in vivo. Moreover, potential signaling pathways were explored to clarify the molecular mechanisms underlying CCA cell proliferation. The results indicated that UCA1 transcription is enhanced in both CCA tissue samples and cell lines, and this overexpression is associated with tumor stage (P = 0.007), lymph node invasion (P = 0.027), TNM stage (P = 0.004) and postoperative recurrence (P = 0.033) of CCA patients. Besides, UCA1 could function as an independent prognostic predictor for overall survival in patients with CCA (P = 0.014). For the part of functional assays, knockdown of UCA1 could attenuate CCA cell growth both in vitro and in vivo. Besides, UCA1 facilitates apoptosis via Bcl-2/caspase-3 pathway. In addition, UCA1 regulates migration and invasion potential of CCA cells by affecting EMT. Furthermore, AKT/GSK-3β axis was activated to upregulate CCND1 expression due to overexpression of UCA1 in CCA. To summary, UCA1 might be a potentially useful prognostic biomarker and therapeutic target for CCA.

Abstract
OBJECTIVES Long non-coding RNAs (lncRNAs) are a group of non-protein-coding RNAs that are greater than 200 nucleotides in length. Increasing evidence indicates that lncRNAs, which may serve as either oncogenes or tumour suppressor genes, play a vital role in the pathophysiology of human diseases, especially in tumourigenesis and progression. Deregulation of lncRNAs impacts different cellular processes, such as proliferation, dedifferentiation, migration, invasion and anti-apoptosis. The aim of this review was to explore the molecular mechanism and clinical significance of long non-coding RNA-activated by transforming growth factor β (lncRNA-ATB) in various types of cancers. MATERIALS AND METHODS In this review, we summarize and analyze current studies concerning the biological functions and mechanisms of lncRNA-ATB in tumour development. The related studies were obtained through a systematic search of Pubmed, Web of Science, Embase and Cochrane Library. RESULTS Long non-coding RNAs-ATB is a novel cancer-related lncRNA that was recently found to exhibit aberrant expression in a variety of malignancies, including hepatocellular carcinoma, colorectal cancer, gastric cancer, and lung cancer. Dysregulation of lncRNA-ATB has been shown to contribute to proliferation, migration and invasion of cancer cells. Long non-coding RNAs-ATB promotes tumourigenesis and progression mainly through competitively binding miRNAs to induce epithelial-mesenchymal transition (EMT). CONCLUSIONS Long non-coding RNAs-ATB likely represents a feasible cancer biomarker or therapeutic target.

Abstract
Regional deposition effects are important in the pulmonary delivery of drugs intended for the topical treatment of respiratory ailments. They also play a critical role in the systemic delivery of drugs with limited lung bioavailability. In recent years, significant improvements in the quality of pulmonary imaging have taken place, however the resolution of current imaging modalities remains inadequate for quantifying regional deposition. Computational Fluid-Particle Dynamics (CFPD) can fill this gap by providing detailed information about regional deposition in the extrathoracic and conducting airways. It is therefore not surprising that the last 15years have seen an exponential growth in the application of CFPD methods in this area. Survey of the recent literature however, reveals a wide variability in the range of modelling approaches used and in the assumptions made about important physical processes taking place during aerosol inhalation. The purpose of this work is to provide a concise critical review of the computational approaches used to date, and to present a benchmark case for validation of future studies in the upper airways. In the spirit of providing the wider community with a reference for quality assurance of CFPD studies, in vitro deposition measurements have been conducted in a human-based model of the upper airways, and several groups within MP1404 SimInhale have computed the same case using a variety of simulation and discretization approaches. Here, we report the results of this collaborative effort and provide a critical discussion of the performance of the various simulation methods. The benchmark case, in vitro deposition data and in silico results will be published online and made available to the wider community. Particle image velocimetry measurements of the flow, as well as additional numerical results from the community, will be appended to the online database as they become available in the future.

Abstract
Diphyllobothrium latum infection in human is not common in China and only 15 cases have been reported since 1927. We document a case of Diphyllobothrium latum infection caused by the ingestion of raw fish in a 23-year-old woman in Dalian (Liaoning Province), and diphyllobothriasis latum in China is briefly reviewed. The patient experienced abdominal discomfort for about 6 months with a history of discharging proglottids in the feces. The morphologic characteristic of the gravid proglottids and eggs were identified as that of Diphyllobothrium latum. The patient was treated with pumpkin seed powder (100g) and betel nut(100g) on an empty stomach. The majority of reported human cases occurred due to the ingestion of raw or uncooked fish, such as pikes, burbots, trouts, perch and salmons. The patient is the first case reported in Dalian (Lianning Province).

Abstract
Objective: This study explored the preoperative prognostic factors of patients with glioblastoma multiforme (GBM) in order to propose a preoperative prognosis estimation model. Methods: The clinical data of 416 patients diagnosed with GBM in Beijing Tiantan Hospital affiliated to Capital Medical University from 2008 to 2015 were retrospectively reviewed.A total of nine factors: gender, age, duration of symptoms, preoperative epilepsy, preoperative muscle weakness, preoperative headache, preoperative KPS score, tumor location and tumor diameter were enrolled in the survival analysis.The significant factors identified by Kaplan-Meier plot were further collected in the multivariate Cox regression analysis.On the basis of multivariate analysis results, a preoperative prognosis estimation model was founded. Results: Univariate analysis showed that Age ≥50 years, without preoperative epilepsy, tumor located in non-frontotemporal lobe, tumor diameter ≥6 cm and preoperative KPS score <70 were prognostic risk factors (P<0.05). Multivariate analysis revealed that Age ≥50 years, without preoperative epilepsy, tumor located in non-frontotemporal lobe were independent risk factors (P<0.05). The prognostic estimation model based on the independent risk factors divided the whole cohort into three subgroups with different survival (P<0.001). Conclusions: The more risk factors, the higher score but poorer prognosis. Patients in the high-risk group had lower gross total resection degree but higher rate of postoperative complications, which suggested that aggressive resection was not suitable for high-risk patients.

Abstract
Objective: To study the predictive and prognostic significance of high-sensitivity modified Glasgow Prognostic Score (HS-mGPS) on the effect of neoadjuvant chemotherapy for advanced gastric cancer. Methods: 117 patients with advanced gastric cancer received neoadjuvant chemotherapy with SOX (oxaliplatin+ S1) or mFOLFOX 6(oxaliplatin+ CF+ 5-FU) regimen. HS-mGPS was calculated according to blood C-reactive protein (CRP) concentration and serum albumin (ALB) level. The correlation between HS-mGPS and clinicopathological characteristics was determined and the predictors of survival were analyzed. Results: 117 patients with stage ⅡB (43 cases), stage Ⅲ (60), and stage Ⅳ (14) received preoperative neoadjuvant chemotherapy. The overall response rate of neoadjuvant chemotherapy was 61.5%(72/117), and the tumor control rate was 88.0% (103/117), with a pathological response rate of 91.5% (107/117). The R0 resection rate was 81.2% (95/117). The median disease-free survival (DFS) was 21.0 (95% CI 6.4-35.6) months. The median overall survival (OS) was 39.0 (95% CI 21.4-56.6) months. Higher HS-mGPS was associated with higher T stage, local lymph-node metastasis, distant metastasis, lower chemotherapy overall response rate and lower pathological response rate (all P<0.05). The univariate analysis and multivariate analysis showed that higher HS-mGPS, presence of local lymph-node metastasis and non R0 resection were associated with poorer DFS and OS (P<0.05). Conclusion: HS-mGPS can be used to predict the benefits of neoadjuvant chemotherapy and as an independent prognostic factor for survival in patients with advanced gastric cancer.

Abstract
Extrahepatic cholangiocarcinoma (ECC) is a deadly disease that often responds poorly to conventional chemotherapy or radiotherapy. Long noncoding RNAs (lncRNAs) play important roles in human cancers, including ECC, and recent studies indicated that the lncRNA prostate cancer-associated transcript 1 (non-protein coding) (PCAT1) is involved in multiple cancers. However, the role of PCAT1 in ECC is unclear. Previously, we showed that PCAT1 is up-regulated in both ECC tissue samples and cell lines. Here, we showed that downregulation of PCAT1 following transfection with silencing RNA reduced ECC cell growth and increased cell apoptosis. Additionally, PCAT1 suppression inhibited ECC cell migration and invasion as determined by transwell assay. Furthermore, we determined that PCAT1 is a competing endogenous for microRNA (miR)-122, with bioinformatics analysis and luciferase-reporter assay results demonstrating that PCAT1 regulated WNT1 expression via miR-122. Moreover, PCAT1 downregulation increased levels of glycogen synthase kinase 3β and significantly decreased β-catenin levels in whole cell lysates and nuclear fractions, indicating that PCAT1 silencing inhibited the Wnt/β-catenin-signaling pathway. We also observed that exogenous expression of WNT1 reversed PCAT1-silencing-induced inhibition of ECC cell growth inhibition. These results indicated that PCAT1 silencing inhibited ECC progression by reducing Wnt/β-catenin signaling through miR-122 repression and WNT1 expression. Our findings revealed an important role of PCAT1 in ECC and suggested that PCAT1 might be a potential ECC-related therapeutic target.

Abstract
Cholangiocarcinoma (CCA) is a fatal disease with increasing worldwide incidence and is characterized by poor prognosis due to its poor response to conventional chemotherapy or radiotherapy. Long non-coding RNAs (lncRNAs) play key roles in multiple human cancers, including CCA. Cancer progression related lncRNA taurine-up-regulated gene 1 (TUG1) was reported to be involved in human carcinomas. However, the impact of TUG1 in CCA is unclear. The aim of this study was to explore the expression pattern of TUG1 and evaluate its clinical significance as well as prognostic potential in CCA. In addition, the functional roles of TUG1 including cell proliferation, apoptosis, migration, invasion and epithelial-mesenchymal transition (EMT), were evaluated after TUG1 silencing. Our data demonstrated up-regulation of TUG1 in both CCA tissues and cell lines. Moreover, overexpression of TUG1 is linked to tumor size (p=0.005), TNM stage (p=0.013), postoperative recurrence (p=0.036) and overall survival (p=0.010) of CCA patients. Furthermore, down-regulation of TUG1 following RNA silencing reduced cell growth and increased apoptosis in CCA cells. Additionally, TUG1 suppression inhibited metastasis potential in vitro by reversing EMT. Overall, our results suggest that TUG1 may be a rational CCA-related prognostic factor and therapeutic target.

Abstract
Rotavirus-related diarrhoea is considered one of the most important diseases in field animal production. In addition to the classic vaccine strategy, a number of studies have utilised probiotics, such as Lactobacillus rhamnosus GG (LGG), to prevent rotavirus-induced diarrhoea. Although it has been partially revealed that Toll-like receptors (TLRs) are involved in the LGG-mediated protection against rotavirus infection, the details of the underlying immunologic mechanisms remain largely unknown. In this study, three-to-four-week-old female BALB/c mice were divided into three groups and orally administered phosphate buffered saline (PBS), PBS plus rotavirus or LGG plus rotavirus, respectively. The differentiation and maturation of dendritic cells (DCs) were then determined by FACS, the expression levels of TLR-3 and nuclear factor kappa beta (NF-κB) were evaluated using real time PCR, and the production of inflammatory cytokines in mesenteric lymph nodes (MLNs) were determined by ELISA. The results demonstrated that rotavirus infection significantly increased the percentage of CD11c+CD11b+CD8a- DCs and decreased the percentage of CD11c+CD11b-CD8a+ DCs in MLNs. By contrast, the presence of LGG significantly decreased the percentage of CD11c+CD11b+CD8a- DCs and increased the percentage of CD11c+CD11b-CD8a+ DCs, which indicates that the differentiation of DCs is involved in the protective effects of LGG. Rotavirus infection also resulted in the increased expression of surface markers such as CD40, CD80 and MHC-II in DCs, and the administration of LGG significantly increased the expression level further. The mRNA levels of TLR-3 and NF-κB in the intestine and MLNs were also significantly increased in the presence of rotavirus, which was further increased in the presence of LGG. The production of inflammatory cytokines was also determined, and the results showed that rotavirus caused the increased production of interleukin (IL)-12 and tumour necrosis factor alpha; this effect was further enhanced by LGG. Meanwhile, although rotavirus infection led to the increased production of IL-6 and IL-10, the presence of LGG significantly decreased the mRNA levels of these cytokines. By contrast, rotavirus infection resulted in the decreased production of interferon gamma (IFN-γ), and the administration of LGG significantly increased the levels of IFN-γ. Taken together, the protective effects of LGG were partially due to the modulation of the differentiation and maturation of DCs, the increased production of TLR-3 and NF-κB, and the modulation of inflammatory cytokines.

Abstract
BACKGROUND A previous study provided evidence for a genetic association between PPP2CA on 5q31.1 and systemic lupus erythematosus (SLE) across multi-ancestral cohorts, but failed to find significant evidence for an association in the Han Chinese population. OBJECTIVES To explore the association between this locus and SLE using data from our previously published genome-wide association study (GWAS). METHODS Single-nucleotide polymorphisms (SNPs) rs7726414 and rs244689 (near TCF7 and PPP2CA in 5q31.1) were selected as candidate independent associations from a large-scale study in a Han Chinese population consisting of 1047 cases and 1205 controls. Subsequently, 3509 cases and 8246 controls were genotyped in two further replication studies. We then investigated the SNPs' associations with SLE subphenotypes and gene expression in peripheral blood mononuclear cells. RESULTS Highly significant associations with SLE in the Han Chinese population were detected for SNPs rs7726414 and rs244689 by combining the genotype data from our previous GWAS and two independent replication cohorts. Further conditional analyses indicated that these two SNPs contribute to disease susceptibility independently. A significant association with SLE, age at diagnosis < 20 years, was found for rs7726414 (P = 0·001). The expression levels of TCF7 and PPP2CA messenger RNA in patients with SLE were significantly decreased compared with those in healthy controls. CONCLUSIONS This study found evidence for multiple associations with SLE in 5q31.1 at genome-wide levels of significance for the first time in a Han Chinese population, in a combined genotype dataset. These findings suggest that variants in the 5q31.1 locus not only provide novel insights into the genetic architecture of SLE, but also contribute to the complex subphenotypes of SLE.

Abstract
Cholangiocarcinoma (CCA) is one of the most malignant human cancers with increasing incidence worldwide. LncRNAs have emerged as gene regulators and prognostic biomarkers in a variety of neoplasms. PANDAR, a novel cancer-related lncRNA, has been reported to be upregulated in diverse human carcinomas. In this study, we aimed to investigate the clinical significance of lncRNA PANDAR in CCA and explore its functional roles in CCA cells including cell proliferation, apoptosis, migration, invasion and epithelial-to-mesenchymal transition (EMT). The results showed that PANDAR was significantly upregulated in CCA tissue specimens and cell lines, and its high expression was closely associated with lymph node invasion (P=0.004), TNM stage (P=0.034) and postoperative relapse (P=0.006) in patients with CCA. Thus, overexpression of PANDAR could serve as an independent prognostic biomarker of CCA. Furthermore, silencing of PANDAR followed by siRNA significantly inhibited cell proliferation and increased apoptosis in CCA cells. In addition, suppression of PANDAR impaired migration and invasion capacity in vitro partly by affecting EMT. Overall, our findings showed that lncRNA PANDAR serves as a novel prognostic biomarker and therapeutic target for CCA.

Abstract
BACKGROUND Platelet derived growth factors (PDGFs) are key components of autocrine and paracrine signalling, both of which play important roles in mammalian developmental processes. PDGF expression levels also relate to oxygen levels. The characteristics of yak PDGFs, which are indigenous to hypoxic environments, have not been clearly described until the current study. MATERIALS AND METHODS We amplified the open reading frame encoding yak (Bos grunniens) platelet derived growth factor-alpha (PDGFA) from a yak skin tissue cDNA library by reverse transcriptase polymerase chain reaction (PCR) using specific primers and Sanger dideoxy sequencing. Expression of PDGFA mRNA in different portions of yak brain tissue (cerebrum, cerebellum, hippocampus, and spinal cord) was detected by quantitative real-time PCR (qRT-PCR). PDGFA protein expression levels and its location in different portions of the yak brain were evaluated by western blot and immunohistochemistry. RESULTS We obtained a yak PDGFA 755 bp cDNA gene fragment containing a 636 bp open reading frame, encoding 211 amino acids (GenBank: KU851801). Phylogenetic analysis shows yak PDGFA to be well conserved, having 98.1% DNA sequence identity to homologous Bubalus bubalus and Bos taurus PDGFA genes. However, 8 nucleotides in the yak DNA sequence and 4 amino acids in the yak protein sequence differ from the other two species. PDGFA is widely expressed in yak brain tissue, and furthermore, PDGFA expression in the cerebrum and cerebellum are higher than in the hippocampus and spinal cord (p > 0.05). PDGFA was observed by immunohistochemistry in glial cells of the cerebrum, cerebellum, and hippocampus, as well as in pyramidal cells of the cerebrum, and Purkinje cell bodies of the hippocampus, but not in glial cells of the spinal cord. CONCLUSIONS The PDGFA gene is well conserved in the animal kingdom; however, the yak PDGFA gene has unique characteristics and brain expression patterns specific to this high elevation species.

Abstract
Cholangiocarcinoma (CCA) is a deadly disease that poorly responds to chemotherapy and radiotherapy and whose incidence has increased worldwide. Furthermore, long noncoding RNAs (lncRNAs) play important roles in multiple biological processes, including tumorigenesis. Specifically, H19, the first discovered lncRNA, has been reported to be overexpressed in diverse human carcinomas, but the overall biological role and clinical significance of H19 in CCA remains unknown. In the present study, expression levels of H19 were investigated in CCA tissues and cell lines and were correlated with clinicopathological features. Moreover, we explored the functional roles of H19 depletion in QBC939 and RBE cells, including cell proliferation, apoptosis, migration, invasion and epithelial-to-mesenchymal transition (EMT). The results indicated that H19 was upregulated in CCA tissue samples and cell lines, and this upregulation was associated with tumor size, TNM stage, postoperative recurrence and overall survival in 56 patients with CCA. Moreover, knockdown of H19 followed by RNA silencing restrained cell proliferation and promoted apoptosis. In addition, H19 suppression impaired migration and invasion potential by reversing EMT. Overall, our findings may help to develop diagnostic biomarkers and therapeutics that target H19 for the treatment of CCA.

Abstract
AIMS To analyse whether some indoleacetic acid (IAA)-secreting plant growth-promoting bacteria can alleviate cadmium (Cd) stress, the role of an Ochrobactrum sp. MGJ11 from rhizosphere of soybean in promoting plant growth, and to evaluate the counteracting Cd effects on soybean. METHODS AND RESULTS Ochrobactrum sp. MGJ11 produced 121·2 mg l-1 of IAA. MGJ11 increased soybean root length, shoot length and biomass by 30·1, 30·8 and 13·4% respectively. In liquid medium, no IAA production was detected in Cd concentration of 100 mg l-1 . In soil with 20-80 mg kg-1 Cd, MGJ11 promoted soybean root elongation (29·4-161·4%) and increased the shoot length (up to 52·7%) and biomass (up to 87·2%). After growing for 38 days, Cd concentrations in the roots of inoculated soybean were lower than in those of noninoculated plants. Only a little Cd (2·6-16·9 μg g-1 ) was translocated from the root to shoot. CONCLUSIONS Ochrobactrum sp. MGJ11 secretes IAA and shows tolerance against Cd. MGJ11 inoculation improves the root length, shoot length and biomass of soybean in both vermiculite and Cd vermiculite, and decreases Cd concentration of soybean root. The characteristics of MGJ11 suggest that it could be used for promoting soybean growth and lowering bioavailability of soil Cd for soybean root. SIGNIFICANCE AND IMPACT OF THE STUDY In this study, we isolated a plant growth-promoting Ochrobactrum with the activity of mitigating Cd toxicity to plant roots. The Ochrobactrum can be considered as a potential bioaugmentation agent that promotes plant growth, especially in some agricultural systems, or that helps in the phytoremediation of Cd-contaminated soil.

Abstract
OBJECTIVE To study the distribution characteristics of lactobacillus in the vaginal mucosa of patients with HPV infection. METHODS The planting density of lactobacillus in vaginal secretions of 95 cases with HPV16/18 infection and 90 cases of normal women of childbearing age were observed by oil microscope. And the strains of vaginal lactobacilli in two groups were analyzed using species-specific polymerase chain reaction (Species-specific PCR) and the distribution of vaginal lactobacilli in patients with HPV16/18 infection were investigated. RESULTS In HPV16/18 infective groups, the planting density of lactobacillus in the vaginal mucosa was 104 (68-186)/HP. It was significantly lower than that of the normal group (234 (161-326)/HP, P<0.05). Compared with the normal group, the positive rates of lactobacillus iners, lactobacillus crispatus, and lactobacillus gasseri were significantly lower in HPV16/18 infection group (P<0.05). CONCLUSION The HPV16/18 infection is associated with the decreased number of lactobacillus and the imbalance of vaginal flora; Lactobacillus iners, lactobacillus crispatus, and lactobacillus gasseri may play a key role in maintaining the vaginal micro ecological environment.

Abstract
Mice are commonly used to study the temporomandibular joint (TMJ) and to model human TMJ disease. However, evaluating TMJ pathology in mice using standard histologic methods is time consuming, labor intensive, and dependent upon investigators’ expertise at consistently orienting and sectioning across tiny specimens. We describe a method that uses confocal microscopy to rapidly and reliably assess indicators of mandibular condyle cartilage pathology in mice. We demonstrate the utility of this method for detecting abnormalities in chondrocyte distribution in mice lacking lubricin (Prg4), the major boundary lubricant of articular cartilage. We further show that the method can provide information about recombination sites and efficiency in mandibular cartilage for Cre-driver strains. Because specimen preparation and data acquisition with confocal microscopy are simple and fast, the method can serve as a primary screening tool for TMJ pathology, before proceeding to complicated, time consuming, secondary analyses.

Abstract
To elucidate the magnetic structure and the origin of the nematicity in FeSe, we perform a high-pressure ^{77}Se NMR study on FeSe single crystals. We find a suppression of the structural transition temperature with pressure up to about 2 GPa from the anisotropy of the Knight shift. Above 2 GPa, a stripe-order antiferromagnetism that breaks the spatial fourfold rotational symmetry is determined by the NMR spectra under different field orientations and with temperatures down to 50 mK. The magnetic phase transition is revealed to be first-order type, implying the existence of a concomitant structural transition via a spin-lattice coupling. Stripe-type spin fluctuations are observed at high temperatures, and remain strong with pressure. These results provide clear evidence for strong coupling between nematicity and magnetism in FeSe, and therefore support a universal scenario of magnetic driven nematicity in iron-based superconductors.

Abstract
This study aimed to investigate the genetic pathogeny of multiple morphological anomalies of the flagella (MMAF), which is a genetically heterogeneous disorder leading to male infertility. Nine patients with severe asthenozoospermia caused by MMAF were recruited. Whole genome sequencing and Sanger sequencing were performed, and we found that four of the nine patients were affected by the same homozygous frameshift mutation c.11726_11727delCT (p.[Pro3909ArgfsTer33]) in exon 73 of dynein axonemal heavy chain 1 ( DNAH1 ) gene. The parents and the sibling of proband 1 were all identified as heterozygous carriers. This mutation was distinct from previously reported DNAH1 mutations associated with MMAF and only affected the East Asian group. Furthermore, the variant DNAH1 protein could not be detected in spermatozoa by Western blot or immunofluorescence staining although DNAH1 mRNA was expressed in the spermatozoa. Scanning electron microscopy and transmission electron microscopy analysis showed the anomalies in sperm flagella morphology and ultrastructure in patients carrying this genetic variant. In conclusion, our results add to knowledge of the genetic pathogeny of MMAF and further confirmed the effectiveness of genetic screening in the diagnosis of MMAF.

Abstract
Cold-inducible RNA binding protein (CIRP) is over-expressed during cold and many other stresses, and could regulate the adaptation to hypothermia. In the present investigation, the objective was to determine the expression of CIRP in adult yak heart, liver, spleen, lung, kidney, brain, ovary, testis and skin by relative quantitative real time polymerase chain reaction (RT-PCR), Western blot and immunohistochemistry from mRNA and protein levels. The CIRP open reading frame encoding was cloned from the domestic yak brain. Results of RT-PCR and Western blot showed the high expression level of CIRP in the heart, kidney, brain, testis and skin, and the lower expression level of CIRP in the lung. Immunohistochemical staining showed CIRP was expressed in the nucleus of neuronal cells, spermatogonia, primary spermatocytes and epidermal cells, and in the cytoplasm of the residual tissues. These observations may provide new data to understand and further study the important role of CIRP protein in the plateau adaptation of the domestic yak on long-term evolution.

Abstract
PURPOSE The aim of this study was to predict the key genes and pathways associated with papillary thyroid carcinoma (PTC). METHODS Based on the microarray data of GSE3467 from Gene Expression Omnibus database, we identified the differentially expressed genes (DEGs) between 9 PTC samples and 9 normal controls. With the identified DEGs, functional enrichment analyses were performed. Additionally, a protein-protein interaction network was constructed to screened out some key gene nodes. These key nodes were then performed clustering analysis and pathway enrichment analysis. Furthermore, human PTC-associated network was constructed based on these key genes to investigate the potential relationships between genes and PTC. RESULTS A total of 651 up-regulated and 692 down-regulated DEGs were identified in PTC samples compared with controls. The up-regulated DEGs, such as complement component 3 (C3), were mainly enriched in hsa04610:Complement and coagulation cascades. The down-regulated DEGs, including paired box 8 (PAX8), peroxisome proliferator-activated receptor gamma (PPARG), and cadherin 1, type 1 were found enriched in hsa05216:Thyroid cancer. Total 33 DEGs were considered as key genes, such as PAX8, PPARG and Jun proto-oncogene (JUN). Disease-associated network analysis found that 15 key genes such as JUN, PPARG and matrix metallopeptidase 9 (MMP9) were involved in this network. CONCLUSIONS DEGs of C3, PPARG, PAX8, JUN and MMP9 were differentially expressed in PTC samples and may be used as potential biomarkers in the diagnosis and treatment of PTC. Additionally, pathways of complement and coagulation cascades and thyroid cancer may also play important roles in the development of PTC.

Abstract
While a number of allergens from house dust mites have been described, much remains to be discovered about allergens from storage mites. Here, next-generation sequencing was combined with MS/MS shotgun proteomics to identify proteins, especially potential allergens from Tyrophagus putrescentiae, commonly found in stored food products, especially flour. cDNAs of suspected allergens were cloned and expressed from bacterial cells, and recombinant allergens were tested for binding to IgE in sera from T. putrescentiae-sensitive patients. These analyses identified three previously uncharacterized allergens, Tyr p 28, Tyr p 35, and Tyr p 36, which have been officially assigned by the WHO/IUIS Allergen Nomenclature Sub-committee. Recombinant proteins rTyr p 28, rTyr p 35, and rTyr p 36 bound with 47.1%, 82.4%, and 70.6% of T. putrescentiae-sensitive sera. We provide here a new method to identify allergens by the combination of transcriptomic and proteomic approaches.

Abstract
Pancreatic cancer is notoriously becoming one of the most devastating human cancers leading to death. However, clinical challenges still remain in diagnosis and treatment of this ticklish cancer. In the present study, the authors identified a new gene, Tectonic 1 (TCTN1), as a key regulator of cell proliferation in pancreatic cancer. Lentivirus-mediated short hairpin RNA (shRNA) was employed to knock down endogenous TCTN1 expression in PANC-1 pancreatic cancer cells. Knockdown of TCTN1 expression potently inhibited cell viability and proliferation, as determined by MTT and colony formation assays. Western blotting analysis also showed that knockdown of TCTN1 suppressed the expression of cdc2, while it induced that of p21 and p27. Flow cytometry analysis showed that depletion of TCTN1 in PANC-1 cells led to cell cycle arrest in the G2/M phase as well as apoptosis. Besides, depletion of TCTN1 led to the increase of Bax and cleavage of PARP-1, but the decrease of bcl2 by western blotting. The data indicate that TCTN1 is indispensable for pancreatic cancer cell proliferation, which provides a novel alternative to targeted therapy of pancreatic cancer and deserves further investigation.

Abstract
BACKGROUND Sip1/Tuftelin Interacting Protein (STIP) is highly conserved from Caenorhabditis elegans to Homo sapiens and has essential biological functions. However, its function in leukemia remains unknown. METHODS Clinic samples and cell model were used in this article to investigate the expression of STIP in lymphoblastic leukemia. The functional research of STIP was performed in ARH-77 by siRNA transfection, immunofluorescence, cell count, cell cycle analysis, qRT-PCR, sub-cellular fractionation assays, immunoprecipitation and western blotting. RESULTS Here, we found that STIP is more highly expressed in both clinical lymphoblastic leukemia samples and cultured leukemia cells than in normal samples. Knockdown of STIP in B lymphoblastic leukemia ARH-77 cells leads to S phase arrest, lower cell proliferation rates, and suppressed AKT and ERK1/2 signaling pathways. Interestingly, when protein phosphatase was inhibited by Calyculin A, STIP knockdown did not result in the dephosphorylation of p-ERK1/2, suggesting the dependence of STIP on protein phosphatase in the regulation of ERK1/2. Among those protein phosphatase inhibited by Calyculin A, PP1γ was found to interact with STIP proven by immunofluorescence and immunoprecipitation assays. The binding of STIP with PP1γ may decrease the phosphatase activity of PP1γ, resulting in hyper-activated ERK1/2 signaling. CONCLUSION In summary, the high expression and activation effect on the ERK1/2 signaling of STIP in lymphoblastic leukemia suggest that STIP would be a potential therapy target or diagnosis marker for leukemia.

Abstract
Approaching the theoretically limiting open circuit voltage (Voc) of solar cells is crucial to optimize their photovoltaic performance. Here, we demonstrate experimentally that nanostructured layers can achieve a fundamentally larger Fermi level splitting, and thus a larger Voc, than planar layers. By etching tapered nanowires from planar indium phosphide (InP), we directly compare planar and nanophotonic geometries with the exact same material quality. We show that the external radiative efficiency of the nanostructured layer at 1 sun is increased by a factor 14 compared to the planar layer, leading to a 70 mV enhancement in Voc. The higher voltage arises from both the enhanced outcoupling of photons, which promotes radiative recombination, and the lower active material volume, which reduces bulk recombination. These effects are generic and promise to enhance the efficiency of current record planar solar cells made from other materials as well.

Abstract
Objective: To study the clinical and pathological features and surgical outcome of eyelid/conjunctival amyloidosis. Methods: It was a retrospective case series study. The clinical and pathological records of 11 patients who were diagnosed as eyelid/conjunctival amyloidosis and had surgical treatment between February 2007 and October 2015 at Beijing Tongren Hospital were analyzed. Routine pathological examinations and Congo red staining were performed. All of the 11 patients received surgical treatment. Seven patients with ptosis underwent surgical excision and ptosis repair. One patient with lower eyelid mass underwent surgical excision and reconstruction of the lower eyelid. One patient with upper eyelid mass underwent surgical excision. Two patients with conjunctival mass underwent surgical excision. Results: In the 11 patients, 6 were male and 5 were female. The mean age was 31 years old, median age was 21 years old, and the range of age was13-59 years old. Eight cases presented as eyelid thickening and nodular growth of the conjunctiva, and 7 of them had ptosis. One case presented as tumor of the upper lid. Two cases presented as conjunctival masses at the semilunar fold. None of the patients were found to have systemic involvement. All of the 11 cases received surgical treatment including excision of the lesions and correction of ptosis when necessary. Pathological examinations confirmed the diagnosis of amyloidosis. Follow up time was 1-9 years. Nine cases were stable, 1 case had progression in the conjunctival lesion and 1 case was lost to follow up. Conclusions: Eyelid/conjunctival amyloidosis usually present as mass or diffuse thickening of the eyelid/conjunctiva. The outcome of surgical treatment was satisfying.(Chin J Ophthalmol, 2016, 52: 775-779).

Abstract
UNLABELLED A search for dark matter linelike signals iss performed in the vicinity of the Galactic Center by the H.E.S.S. experiment on observational data taken in 2014. An unbinned likelihood analysis iss developed to improve the sensitivity to linelike signals. The upgraded analysis along with newer data extend the energy coverage of the previous measurement down to 100 GeV. The 18 h of data collected with the H.E.S.S. array allow one to rule out at 95% C.L. the presence of a 130 GeV line (at l=-1.5°, b=0° and for a dark matter profile centered at this location) previously reported in Fermi-LAT data. This new analysis overlaps significantly in energy with previous Fermi-LAT and H.E.S.S. RESULTS No significant excess associated with dark matter annihilations was found in the energy range of 100 GeV to 2 TeV and upper limits on the gamma-ray flux and the velocity weighted annihilation cross section are derived adopting an Einasto dark matter halo profile. Expected limits for present and future large statistics H.E.S.S. observations are also given.

Abstract
A new low-power application-specific integrated circuit (ASIC) for Cadmium Zinc Telluride (CZT) detectors for single-photon emission computed tomography (SPECT) application is being developed at BNL. As the first step, a 32-channel prototype ASIC was designed and tested recently. Each channel has a preamplifier followed by CR-RC3 shaping circuits and three independent energy bins with comparators and 16-bit counters. The ASIC was fabricated with TSMC 0.35-μm complementary metal-oxide-semiconductor (CMOS) process and tested in laboratories. The power consumption is around 1 mW/ch with a 2.5-V supply. With a gain of 400 mV/fC and the peaking time of 500 ns, the equivalent noise charge (ENC) of 360 e- has been measured in room temperature while the crosstalk rate is less than 0.3%. The 10-bit DACs for global thresholds have an integral nonlinearity (INL) less than 0.56% and differential nonlinearity (DNL) less than 0.33%. In the presentation, we will report the detailed test results with this ASIC.

Abstract
Lung cancer is one of the most malignant tumors worldwide with a high mortality rate, which has not been improved since several decades ago. FOX gene family members have been reported to play extensive roles in regulating many biological processes and disorders. In order to clarify the contribution of FOX gene family members in lung cancer biology, we performed expression profiling analysis of FOX gene family members from FOXA to FOXR in lung cancer cell lines and tissue specimens by Real-time PCR, western blot and immunohistochemistry analysis. We found that FOXE1 was the only gene which was over-expressed in six out of eight lung cancer cell lines and human cancer tissue specimens (28 out of 35 cases with higher expression and 7 out of 35 cases with moderate expression). Further investigation showed that MMP2 gene was up-regulated, and autophagy markers such as LC3B, ATG5, ATG12 and BECLIN1, were down-regulated concomitant with the increase of FOXE1. These results implicated that FOXE1 may be an important regulator by targeting autophagy and MMPs pathways in lung cancer development.

Abstract
The inner region of the Milky Way halo harbors a large amount of dark matter (DM). Given its proximity, it is one of the most promising targets to look for DM. We report on a search for the annihilations of DM particles using γ-ray observations towards the inner 300 pc of the Milky Way, with the H.E.S.S. array of ground-based Cherenkov telescopes. The analysis is based on a 2D maximum likelihood method using Galactic Center (GC) data accumulated by H.E.S.S. over the last 10 years (2004-2014), and does not show any significant γ-ray signal above background. Assuming Einasto and Navarro-Frenk-White DM density profiles at the GC, we derive upper limits on the annihilation cross section ⟨σv⟩. These constraints are the strongest obtained so far in the TeV DM mass range and improve upon previous limits by a factor 5. For the Einasto profile, the constraints reach ⟨σv⟩ values of 6×10^{-26} cm^{3} s^{-1} in the W^{+}W^{-} channel for a DM particle mass of 1.5 TeV, and 2×10^{-26} cm^{3} s^{-1} in the τ^{+}τ^{-} channel for a 1 TeV mass. For the first time, ground-based γ-ray observations have reached sufficient sensitivity to probe ⟨σv⟩ values expected from the thermal relic density for TeV DM particles.
