Abstract
Long non-coding RNAs (lncRNAs) play a pivotal role in tumorigenesis, exemplified by the recent finding that lncRNA maternally expressed gene 3 (MEG3) inhibits tumor growth in a p53-dependent manner. Acute myeloid leukemia (AML) is the most common malignant myeloid disorder in adults, and TP53 mutations or loss are frequently detected in patients with therapy-related AML or AML with complex karyotype. Here, we reveal that MEG3 is significantly downregulated in AML and suppresses leukemogenesis not only in a p53-dependent, but also a p53-independent manner. In addition, MEG3 is proven to be transcriptionally activated by Wilms’ tumor 1 (WT1), dysregulation of which by epigenetic silencing or mutations is causally involved in AML. Therefore MEG3 is identified as a novel target of the WT1 molecule. Ten–eleven translocation-2 (TET2) mutations frequently occur in AML and significantly promote leukemogenesis of this disorder. In our study, TET2, acting as a cofactor of WT1, increases MEG3 expression. Taken together, our work demonstrates that TET2 dysregulated WT1-MEG3 axis significantly promotes AML leukemogenesis, paving a new avenue for diagnosis and treatment of AML patients.

Abstract
PURPOSE Androgen plays an important role in the progression of prostate cancer. In the present study, novel magnetic molecularly imprinted polymers (MMIPs) with good biocompatibility were produced for the selective separation and inhibition of testosterone in prostate cancer cells. MATERIALS AND METHODS MMIPs were prepared by using magnetic nanospheres, gelatin, and testosterone as the supporting materials, functional monomer, and the template molecule, respectively. The characterization of the resultant products was investigated by transmission electron microscopy, X-ray diffraction, and vibrating sample magnetometry. To test whether MMIPs can remove testosterone in biologic samples, human LNCaP (androgen-dependent) and C4-2 (androgen-independent) prostate cancer cells were selected as cell models. The translocation of androgen receptor (AR) was detected by immunofluorescence assay, and the expression of PSA mRNA was detected by real-time quantitative polymerase chain reaction analysis. Cell flow cytometry analysis was performed to detect cell cycle arrest. RESULTS The synthesized nanomaterials (MMIPs) possessed high crystallinity, satisfactory superparamagnetic properties, and uniform imprinted shell, and exhibited high adsorption capacity, fast kinetics, and high selectivity for testosterone. Moreover, the obtained imprinted nanomaterials could selectively enrich and detect testosterone in the LNCaP cell samples as a solid-phase extractant coupled with high-performance liquid chromatography. In addition, the MMIPs could freely enter prostate cancer cells and suppress the translocation of AR into the cell nucleus. We further found that MMIPs inhibited upregulation of AR downstream target genes in LNCaP and C4-2 cells; also, MMIPs inhibited cell growth and induced obvious cell cycle arrest in androgen-dependent LNCaP cells, but had no obvious effect on androgen-independent C4-2 cells. CONCLUSION Our results indicate that the obtained imprinted nanomaterials can specifically and effectively bind testosterone and recover it from prostate cancer cells. Moreover, the MMIPs can freely enter prostate cancer cells and block the activation of testosterone-AR pathway. Thus, the MMIPs may be a new option for antiandrogen therapy in prostate cancer.

Abstract
Objective: To investigate the expression of LIM and SH3 protein 1 (LASP1) in renal cell carcinoma and its significance in the invasion and migration of renal clear cell carcinoma 786-O cell line. Methods: The expression level of LASP1 in 41 cases of renal cell carcinoma tissues and normal renal tissues was analyzed by immunohistochemistry. The relationship between the expression level of LASP1 and clinical characteristics was further analyzed. Expression of LASP1 in 10 cases of tumor tissues with or without lymph node metastasis was analyzed by Western blot. Furthermore, small interfering RNA (siRNA) targeting LASP1 was constructed and transfected into 786-O cells to downregulate LASP1 expression. The interference effect of LASP1 siRNA on LASP1 protein and the expression of related proteins in epithelial mesenchymal transition (EMT) pathway were detected by Western blot. The effects of LASP1 knockdown on cell proliferation, migration and invasion and gene expression were then assessed using CCK8 assay, transwell cell migration system and western blot analysis, respectively. Results: The positive rate of LASP1 expression in renal clear cell carcinoma tissues was 90.2% (37/41), which was significantly higher than that in the adjacent tissues (29.3%, P=0.002). The expression of LASP1 in renal cell carcinoma was positively correlated with lymph node metastasis and TNM stage of renal cell carcinoma (P<0.05). The results of Western blot showed that LASP1 (0.696±0.053) was highly expressed in renal cell carcinoma (1.459±0.628), especially in cases with lymph node metastasis (2.692±0.186, P<0.05). The LASP1 siRNA remarkably down-regulated the expression of LASP1 protein in 786-O cells. The abilities of proliferation, invasion and migration of 786-O cells were decreased significantly in the LASP1 siRNA groups.The relative expression of E-cadherin protein in the siRNA group (0.848±0.020) was significantly higher than those in the siRNA-NC group (0.671±0.018) and control group (0.691±0.037, P<0.05). The relative expression of N-cadherin protein in the siRNA group (0.449±0.047) was significantly lower than those in the siRNA-NC group (0.613±0.018) and control group (0.633±0.045, P<0.05). The relative expression of vimentin protein in the siRNA group (0.477±0.029) was significantly lower than those in the siRNA-NC group (0.598±0.069) and control group (0.633±0.045, P<0.05 for both). Conclusions: LASP1 is highly expressed in renal clear cell carcinoma, which is closely related to the development of the cancer. The effects of LASP1 on the invasion and migration of 786-O cells and lymph node metastasis may be related to the EMT.

Abstract
OBJECTIVE To evaluate the association of prostate volume, PSAD and F/T with prostate cancer detection rate in males with a total PSA of 4-10 μg/L. METHODS Clinical data of 196 patients who underwent prostate biopsy from November 2006 to September 2010 and with a PSA of 4-10 μg/L were retrospectively analyzed. The association of detection rate of prostate cancer with prostate volume, prostate specific antigen density PSAD) and free PSA/total PSA ratio (F/T) was analyzed by Spearman coefficient, receiver operating characteristic curve and logistic regression analysis. RESULTS The prostate volume, PSAD and F/T had a significant association with detection rate of prostate cancer (P<0.05 for all). The odd ratio was 0.96, 1.91 and 0.02, respectively. The area under curve (AUR) was 0.31, 0.66 and 0.63, respectively. The cancer detection rate was decreased along with the increase of prostate volume. When PSAD 0.15 ng·ml(-1)·ml(-1) was used as the cut-off value, the sensitivity, specificity, positive prediction rate and negative prediction rate was 72.3%, 51.1%, 42.3% and 21.2%, respectively. When the patients were divided by prostate volume into <19.9, 20-39.9, 40-59.9, 60-79.9 and >80 ml subgroups, the cancer detection rate of each subgroup was 50.0%, 45.6%, 30.8%, 15.4% and 5.6%, respectively. CONCLUSION In patients with a total PSA of 4-10 μg/L, the prostate cancer detection rate has a significant association with prostate volume, PSAD and F/T.

Abstract
The objective of this study was to explore the expressions and significance of NDRG1 (N-myc downregulated gene family 1), VEGF (vascular endothelial growth factor) and Ki-67 in lesions of Condyloma Acuminatum (CA). Immunohistochemistry was adopted to measure the expressions of NDRG1, VEGF and Ki-67 in 48 cases of CA and 18 normal skin controls. The positive rates of NDRG1, VEGF and Ki-67 were 63. 83.33% (40/48), 93.75% (45/48) and 85.42% (41/48) in the CA tissues, and 27.78% (5/18), 94.44%(17/18) and 61.11% (11/18) in the controls, respectively. The intensities of the expressions of NDRG1, VEGF and Ki-67 in CA tissues were significantly higher than those in the controls. There were significant differences both in the positive rates and the expression intensities of NDRG1, VEGF and Ki-67 between the two groups (P less than0.05). The Spearmans Rank-Order Correlation analysis indicated that the expressions of NDRG1 protein and VEGF protein were positively correlated by the Spearmans Rank-Order Correlation analysis (r = 0.346, P=0.016). For the CA tissues with high expressions of NDRG1 and VEGF, NDRG1 and VEGF influenced both the occurrence and development of CA.

Abstract
Gastrointestinal (GI) metastasis of hepatocellular carcinoma is very rare. This is the first report of post-transplantation gastric metastasis. A 43-year-old man with a history of hepatitis B-related hepatocellular carcinoma (HCC) in the right anterior segment of the liver received an orthotopic liver transplant. Three months after the transplantation, pulmonary metastasis was found by chest computed tomography, and he received 1 course of gamma knife treatment. He complained of melena with anemia 17 months post liver transplantation. Abdominal CT scan showed new occupying lesions in the liver and a mass in the stomach and around the spleen with embolus in the splenic vein. Endoscopy revealed a large irregular cauliflower-like mass in fundus with ulceration and bleeding on the surface. He received symptomatic treatment, but died of cancer-related bleeding 4 months later. GI bleeding may due to gastric metastasis after liver transplantation.

Abstract
We investigated the associations between Beclin-1 and microRNA-30a (miR-30a) expression and the severity and treatment response in colorectal cancer (CRC). Our sample size consisted of 139 CRC patients who were treated with surgery alone. Immunohistochemistry was used to investigate the expression and prognostic significance of Beclin-1 in CRC, while the weak expression of Beclin-1 in normal tissue was used as the basis for assessing tumors (control group). Real-time reverse transcription-polymerase chain reaction quantified miR-30a levels. The expression levels of Beclin-1 and miR-30a were associated with clinical variables and prognoses. Beclin-1 was expressed more highly in CRC tissues than in controls. This expression was related to gender (P = 0.023), histological grade (P = 0.006), M stage (P = 0.004), tumor node metastasis stage (P = 0.020), vascular invasion, and nodal involvement. Patients with higher Beclin-1 expression levels had higher survival rates (P = 0.08) than patients with lower Beclin-1 expression levels. Beclin-1 was a prognostic indicator (P < 0.05) in a multivariate analysis. Beclin-1 was overexpressed in CRC tissues and was correlated with lower levels of miR-30a (P < 0.05, r = -0. 4189). In conclusion, Beclin-1 was a good prognostic indicator in CRC and was correlated with survival rate. Beclin-1 is important in the growth and metastasis of CRC. Apoptosis in CRC might be due to the increased autophagy induced by decreased levels of miR-30a.

Abstract
Idiopathic dilated cardiomyopathy (IDC) has been hypothesized as a multifactorial disorder initiated by an environment trigger in individuals with predisposing human leukocyte antigen (HLA) alleles. Published data on the association between HLA-DR3 antigen and IDC risk are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed. Studies were identified by searching the PUBMED and Embase database (starting from June 2015). A total of 19 case-control studies including 1378 cases and 10383 controls provided data on the association between HLA-DR3 antigen and genetic susceptibility to IDC. Overall, significantly decreased frequency of HLA-DR3 allele (OR=0.72; 95%CI=0.58-0.90; P=0.004) was found in patients with IDC compared with controls. When stratified by myocardial biopsy or non-biopsy cases, statistically decreased risk was found for IDC in myocardial biopsy cases (OR=0.69; 95%CI=0.57-0.84; P=0.0003). In the subgroup analysis by ethnicity, borderline statistically significantly decreased risk was found among Europeans from 12 case-control studies (OR=0.76; 95%CI=0.58-1.00; P=0.05). In conclusion, our results suggest that individuals with HLA-DR3 antigen may have a protective effect against IDC.

Abstract
Contact force (CF) sensing technology allows real-time monitoring during catheter
ablation for atrial fibrillation (AF). However, the effect of CF sensing technology
on procedural parameters and clinical outcomes still needs clarification. Because of
the inconsistent results thus far in this area, we performed a meta-analysis to
determine whether CF sensing technology can improve procedural parameters and
clinical outcomes for the treatment of AF. Studies examining the benefits of CF
sensing technology were identified in English-language articles by searching the
MEDLINE, Web of Science, and Cochrane Library databases (inception to May 2015). Ten
randomized, controlled trials involving 1834 patients (1263 males, 571 females) were
included in the meta-analysis (681 in the CF group, 1153 in the control group).
Overall, the ablation time was significantly decreased by 7.34 min (95%CI=-12.21 to
-2.46; P=0.003, Z test) in the CF group compared with the control group. CF sensing
technology was associated with significantly improved freedom from AF after 12 months
(OR=1.55, 95%CI=1.20 to 1.99; P=0.0007) and complications were significantly lower in
the CF group than in the control group (OR=0.50, 95%CI=0.29 to 0.87; P=0.01).
However, fluoroscopy time analysis showed no significantly decreased trend associated
with CF-guided catheter ablation (weighted mean difference: -2.59; 95%CI=-9.06 to
3.88; P=0.43). The present meta-analysis shows improvement in ablation time and
freedom from AF after 12 months in AF patients treated with CF-guided catheter
ablation. However, CF-guided catheter ablation does not decrease fluoroscopy
time.

Abstract
MicroRNAs (miRNAs) are a class of non-coding endogenous negative regulators that regulate gene expression at both the transcriptional and post-transcriptional levels. However, little is known about the expression characteristics of miRNAs during pollen development in Brassica oleracea. In this study, five known and three novel miRNAs were identified and their expression patterns were compared in the flower buds of B. oleracea using stem-loop reverse transcription polymerase chain reaction (RT-PCR) and quantitative real-time PCR. The results revealed that the eight miRNAs were constantly expressed during pollen development but exhibited different expression patterns during the five developmental stages of the flower buds between the cytoplasmic male sterile (CMS) line and its fertile maintainer. The highest miRNA expression levels occurred at the uninucleate microspore stage in the fertile line Bo01-12B and at the bicellular pollen stage in the CMS line Bo01-12A. Potential target genes for the miRNAs were predicted and analyzed, and suggested that miRNAs are involved in the regulation of target genes related to pollen development. The results of this study further our understanding of the regulatory role of miRNAs in pollen development.

Abstract
Coronary angiography can be a high-risk condition for the incidence of contrast-induced nephropathy (CIN) in elderly patients. Reduced glutathione, under a variety of mechanisms, may prevent CIN in this procedure. We prospectively examined whether hydration with reduced glutathione is superior to hydration alone for prevention of CIN in an elderly Han Chinese population. A total of 505 patients (271 males and 234 females) aged 75 years or older who underwent non-emergency coronary angiography or an intervention were randomly divided into two groups. The treatment group received hydration with reduced glutathione (n=262) and the control group received hydration alone (n=243). Serum creatinine and blood urea nitrogen levels were measured prior to coronary angiography and 48 h after this procedure. The primary endpoint was occurrence of CIN, which was defined as 25% or 44.2 µmol/L above baseline serum creatinine levels 48 h after the procedure. The overall incidence of CIN was 6.49% in the treatment group and 7.41% in the control group, with no significant difference between the groups (P=0.68). In subgroup analysis by percutaneous coronary intervention, no significant differences were found between the two groups. In summary, reduced glutathione added to optimal hydration does not further decrease the risk of CIN in elderly patients undergoing coronary angiography or an intervention.

Abstract
BACKGROUND Whether a combination of chemotherapy and erlotinib is beneficial for advanced non-small cell lung cancer (NSCLC) remains controversial. This study aimed to summarize the currently available evidence and compare the efficacy and safety of chemotherapy plus erlotinib versus chemotherapy alone for treating advanced NSCLC. METHODS EMBASE, PubMed, and the Cochrane Central Register of Controlled Trials were searched for relevant studies. Our protocol was registered in PROSPERO (CRD42014015015). RESULTS Nine randomized controlled trials with a total of 3599 patients were included. Compared to chemotherapy alone, chemotherapy plus erlotinib was superior in PFS (HR = 0.76 [95% CI 0.62, 0.92], P = 0.006), and no statistically significant difference was observed in OS (HR = 0.94 [95% CI 0.86, 1.03], P = 0.16). Intercalated erlotinib plus chemotherapy demonstrated improvements in PFS (HR = 0.67 [95% CI 0.50, 0.91], P = 0.009) and OS (HR = 0.82 [95% CI 0.69, 0.98], P = 0.03). Continuous erlotinib plus chemotherapy treatment failed to demonstrate improvements in PFS (HR = 0.91 [95% CI 0.80, 1.04], P = 0.16) and OS (HR = 0.98 [95% CI 0.89, 1.09], P = 0.75). The association of chemotherapy plus erlotinib with improvement in PFS was significant in never smoking patients (HR = 0.46 [95% CI 0.37, 0.56], P<0.00001) but not in smoking patients (HR = 0.70 [95% CI 0.49, 1.00], P = 0.05). Among patients with EGFR mutant tumors, chemotherapy plus erlotinib demonstrated significant improvements in PFS (HR = 0.31 [95% CI 0.17, 0.58], P = 0.0002) and OS (HR = 0.52 [95% CI 0.30, 0.88], P = 0.01). Among patients with EGFR wild-type tumors, no statistically significant difference was observed with respect to PFS (HR = 0.87 [95% CI 0.70, 1.08], P = 0.21) and OS (HR = 0.78 [95% CI 0.59, 1.01], P = 0.06). CONCLUSION Combination of chemotherapy and erlotinib is a viable treatment option for patients with NSCLC, especially for patients who never smoked and patients with EGFR mutation-positive disease. In addition, intercalated administration is an effective combinatorial strategy.

Abstract
OBJECTIVE This study examined the usefulness of nasal Duo positive airway pressure (DuoPAP) in the treatment of very low birth weight preterm infants with neonatal respiratory distress syndrome (NRDS). PATIENTS AND METHODS Eighty-five very low birth weight preterm infants with NRDS were randomly divided into two groups. Forty-five infants were treated with DuoPAP, while 40 infants were treated using nasal continuous positive airway pressure (nCPAP). The study outcomes were pH, PaCO, PaO₂, oxygenation index (PaO₂/FiO₂), and the number of failure cases at 1, 12, and 24 hours after non-invasive respiratory support. RESULTS At all studied time points, after non-invasive respiratory support, PaCO₂, PaO₂ and oxygenation index were significantly (p < 0.05) better in the nasal DuoPAP group compared with nasal CPAP group. In addition, rates of failure of assisted ventilation (respectively, 4.44% vs. 22.50%) and the occurrence of apnea (13.33% vs. 32.50%) were significantly (p < 0.05) better in the nasal DuoPAP group. Other parameters (such as duration of noninvasive ventilation, number of retinopathies of premature children, intraventricular hemorrhages, or periventricular leukomalacias) were comparable between both non-invasive regimen. CONCLUSIONS Nasal DuoPAP better improves oxygenation, reduces CO₂ retention, and diminishes the need for invasive mechanical ventilation and complications in the treatment of NRDS.

Abstract
OBJECTIVE The aim of this study was to identify the hub genes and dysregulated pathways of hepatocellular carcinoma (HCC) and explore the molecular mechanism of the biological process associated with HCC. MATERIALS AND METHODS Microarray data were got from NCBI Gene Expression Omnibus (GEO) database. The most significant top 100 up-regulated gene signatures and top 100 down-regulated gene signatures were identified by integrated analysis of the multiple microarray datasets using a novel model genome-wide relative significance (GWRS) and genome-wide global significance (GWGS). Gene Ontology (GO) enrichment analysis and pathway analysis of those genes were performed based on Gene Ontology website and Kyoto Encyclopedia of Genes and Genomes (KEGG). Protein-protein interaction (PPI) network was constructed using Cytoscape 2.1. In addition, we analysed the significantly dysregulated signaling pathways across the PPI network and KEGG pathway analysis. RESULTS We screened 2920 up-regulated and 2231 down-regulated gene signatures across multiple studies by GWRS and GWGS. The top 100 up-regulated and top 100 down-regulated gene signatures were selected for further research. GO enrichment analysis showed that these genes significantly enriched in terms of mitosis (p = 5.83×10-20), nuclear division (p = 5.83×10-20) and M phase of mitotic cell cycle (p = 9.39×10-20). The most significant terms of KEGG pathway included cell cycle (p = 1.33×10-8), oocyte meiosis (p = 1.41×10-4), drug metabolism (p = 2.15×10-4) and p53 signaling pathway (p = 3.57×10-4). PPI network suggested that BIRC5, CDC20, CCNB1, BUB1B, MAD2L1 and CDK1 were important significant genes which were considered as hub genes. Across the PPI and pathway, cell cycle, oocyte meiosis and p53 signaling pathway were the significantly dysregulated pathways. CONCLUSIONS Our study displayed robust gene signatures in HCC. It showed that the dysregulations of cell cycle, oocyte meiosis, p53 signaling pathway and progesterone-mediated oocyte maturation pathway were closely associated to the development and progression of HCC. Besides, genes BIRC5, CDC20, CCNB1, BUB1B, MAD2L1 and CDK1 as the hub genes might play important roles for diagnosing and therapy of HCC.
