Abstract
OBJECTIVE To investigate the prevalence of early trauma and resilience among adolescents in Wuhan, and explore the relationship between early trauma and resilience. METHODS Totally 4871 students aged 10-16 years were chosen by cluster sampling in Wuhan city from September to October 2015. All subjects completed self-report questionnaires, including general information, the Childhood Trauma Questionnaire( CTQ), and the Connor Davidson Resilience Scale( CD-RISC). RESULTS The mean score of CD-RISC of the total sample was( 64. 70 ± 18. 34). Statistical significance in different gender( t = 5. 373, P<0. 001), age( F = 49. 401, P<0. 001), single child( t = 3. 529, P<0. 001), levels of mother's education( F = 36. 129, P< 0. 001), relationship between parents( F = 89. 831, P < 0. 001), family economic status( F = 36. 547, P<0. 001). The rate of early trauma was 30. 1%. Male( χ~2= 42. 272, P < 0. 001), lower levels of mother 's education( χ~2= 44. 345, P < 0. 001), poorer relationship between parents( χ~2= 133. 045, P < 0. 001), and worse family economic status( χ~2= 31. 231, P<0. 001) were associated with increased risk of early trauma. The scores of emotional abuse, physical abuse, sexual abuse, emotional neglect and physical neglect were negatively correlated with the scores of CD-RISC( r followed by-0. 256, -0. 107, -0. 053, -0. 355 and-0. 308, P<0. 01). Regression analysis implied female, older age, emotional abuse, emotional neglect, and physical neglect( B followed by-0. 156, -0. 117, -0. 109, -0. 214 and-0. 149, P < 0. 01) of primary and middle school students assumed predictive resilience. CONCLUSION Emotional abuse, emotional neglect, and physical neglect are negatively associated with resilience among children and adolescent. The result suggest that reducing emotional abuse, emotional neglect and physical neglect experience may contribute to child resilience.

Abstract
Background Nivolumab is approved for the treatment of advanced renal cell carcinoma (RCC). However, traditional overall survival (OS) or progression-free survival (PFS) do not reflect patient prognosis after initial management. Therefore, this study aimed to evaluate conditional overall survival (COS) and conditional progression-free survival (CPFS) in patients with advanced RCC treated with nivolumab. Material/Methods There were 847 patients with advanced RCC treated with first-line nivolumab plus ipilimumab (n=425) and sunitinib (n=422), and 821 patients were treated with second-line nivolumab (n=410) and everolimus (n=411). Primary endpoints were COS and CPFS. Individual patient data of PFS and OS were digitally reconstructed from two large randomized controlled trials (CheckMate 025 and CheckMate 214). Results In first-line treatment, compared with sunitinib, improvement of one-year CPFS for the nivolumab plus ipilimumab group after living for 0.5 and 0.75 years were 14% (from 53.0% to 67.0%) and 16% (from 57.0% to 73.0%) higher than the one-year PFS of 6.5% (from 42.9% to 49.4%), with similar results for one-year COS following first-line treatment. For second-line treatment, compared with everolimus, the improvement of one-year CPFS for the nivolumab group after living for 0.5 and 0.75 years were 19% (from 25.0% to 44.0%) and 19% (from 27.0% to 46.0%) and significantly higher than the one-year PFS of 4.5% (from 18.5% to 23.0%). Conclusions Survival benefit for patients with advanced RCC from nivolumab (plus ipilimumab) compared with sunitinib was more evident from conditional survival (CS) analysis of first-line treatment.

Abstract
Background: As conditional survival could provide more relevant prognostic information at each follow-up time, the present study aimed to assess conditional overall survival (COS) based on two cohorts and assess the risks of death due to renal cell carcinoma (RCC) vs. other causes. Methods: The Fudan University Shanghai Cancer Center (FUSCC) and Surveillance, Epidemiology, and End Results (SEER) database were used as the source of data for our analysis. COS and cancer-specific survival were evaluated using the Kaplan–Meier method. Results: A total of 90,927 patients (SEER cohort = 88,807, FUSCC cohort = 2,120) were enrolled. Our results suggest that hazards of other causes-related death were always higher than that of cancer-specific death in low-risk RCC patients, but lower in metastatic RCC patients. It exceeded that of cancer-specific death by 8 years in high-risk RCC patients. Only in metastatic RCC patients, the COS improved markedly with survivorship increasing. After surviving 1, 2, 3, 4, and 5 years, the 5 years COS increased by +10, +18, +23, +29, and 35% (the observed 5 years OS: 12%), respectively. Conclusions: COS can better help patients with metastatic RCC rather than other RCC patients. Additionally, COS brings optimism for metastatic RCC patients with expected poorer prognosis psychologically.

Abstract
Invading cancer cells extend cell protrusions, which guide cancer-cell migration and invasion, eventually leading to metastasis. The formation and activity of cell protrusions involve the localization of molecules and organelles at the cell front; however, it is challenging to precisely isolate these subcellular structures at the single-cell level for molecular analysis. Here, we describe a newly developed microfluidic platform capable of high-throughput isolation of cell protrusions at single-cell precision for profiling subcellular gene expression. Using this microfluidic platform, we demonstrate the efficient generation of uniform cell-protrusion arrays (more than 5000 cells with protrusions) for a series of cell types. We show precise isolation of cell protrusions with high purity at single-cell precision for subsequent RNA-Seq analysis, which was further validated by RT-qPCR and RNA FISH. Our highly controlled protrusion isolation method opens a new avenue for the study of subcellular functional mechanisms and signaling pathways in metastasis.

Abstract
Background: Early biochemical recurrence (BCR) was considered as a sign for clinical recurrence and metastasis of prostate cancer (PCa). The purpose of the present study was to identify a lncRNA-based nomogram that can predict BCR of PCa accurately. Materials and methods: Bioinformatics analysis, such as propensity score matching (PSM) and differentially expressed genes (DEGs) analyses were used to identify candidate lncRNAs for further bioinformatics analysis. LASSO Cox regression model was used to select the most significant prognostic lncRNAs and construct the lncRNAs signature for predicting BCR in discovery set. Additionally, a nomogram based on our lncRNAs signature was also formulated. Both lncRNAs signature and nomogram were validated in test set. GSEA was carried out to identify various gene sets which share a common biological function, chromosomal location, or regulation. Results: A total of 457 patients with sufficient BCR information were included in our analysis. Finally, a five lncRNAs signature significantly associated with BCR was identified in discovery set (HR=0.44, 95%CI: 0.27-0.72, C-index = 0.63) and validated in test set (HR=0.22, 95%CI: 0.09-0.56, C-index = 0.65). Additionally, the lncRNAs-based nomogram showed significant performance for predicting BCR in both discovery set (C-index = 0.74) and test set (C-index = 0.78). Conclusion: In conclusion, our lncRNAs-based nomogram is a reliable prognostic tool for BCR in PCa patients. In addition, the present study put forward the direction for the further investigation on the mechanism of PCa progression.

Abstract
Tackling microbial infection associated with biomaterial surfaces has been an urgent need. Synthetic β-peptide polymers can mimic host defense peptides and have potent antimicrobial activities without driving the bacteria to develop antimicrobial resistance. Herein, we demonstrate a plasma surface activation-based practical β-peptide polymer modification to prepare antimicrobial surfaces for biomedical materials such as thermoplastic polyurethane (TPU), polytetrafluoroethylene, polyvinyl pyrrolidone, polyvinyl chloride, and polydimethylsiloxane. The β-peptide polymer-modified surfaces demonstrated effective killing on drug-resistant Gram-positive and Gram-negative bacteria. The antibacterial function retained completely even after the β-peptide polymer-modified surfaces were stored at ambient temperature for at least 2 months. Moreover, the optimum β-peptide polymer (50:50 DM-Hex)-modified surfaces displayed no hemolysis and cytotoxicity. In vivo study using methicillin-resistant Staphylococcus aureus (MRSA)-pre-incubated TPU-50:50 DM-Hex surfaces for subcutaneous implantation revealed a 3.4-log reduction of MRSA cells after the implantation for 11 days at the surrounding tissue of implanted TPU sheet and significant suppression of infection, compared to bare TPU control. These results imply promising and practical applications of β-peptide polymer tethering to prepare infection-resistant surfaces for biomedical materials and devices.

Abstract
Purpose Urethral carcinoma (UC), as a rare tumor, is not widely studied. There have been no systematic studies of rare pathological types of UC. We conducted this study to further investigate rare pathological types of primary urethral carcinoma (PUC). Materials and methods We used the population-based Surveillance, Epidemiology, and End Results (SEER) database to evaluate prognostic factors in rare pathological types of PUC. From 1978 to 2015, 2,651 and 257 cases were identified in the SEER database as common and rare pathological types of PUC, respectively. Overall and cancer-specific survival (CSS) times were computed using the Kaplan–Meier method, and the Cox proportional hazards analysis was used to evaluate patient age at diagnosis, gender, race, and TNM stage. Results The median overall survival (OS) rates were 36 and 59 months for rare and common pathological groups, respectively, and their respective 10-year OS rates were 31.9% and 42.4%, respectively. The median CSS rate was 61 months for the rare pathological group. Through multivariate analysis, it was found that age, race, T stage, and M stage were independent prognostic risk factors for rare pathological type of urethral cancer. In the age group, the HR ratio of patients aged older than 60 years and younger or equal to 60 years was 2.778 (P<0.001). The HR ratio of other races to Whites was 1.444 (P=0.040). In TNM staging, the HR ratio between T3–T4 and Ta–T2 was 2.386 (P=0.046), and the HR value of M1 and M0 was 5.847 (P<0.001). Conclusion Age, race, T stage, and M stage were predictive of OS and CSS in rare pathological PUC.

Abstract
Background To compare the predictive value of the current AJCC stage grouping for renal cell carcinoma (RCC) to our modifications. Patients and methods A total of 2120 patients with RCC from Fudan University Shanghai Cancer Center (FUSCC) database and 74 506 counterparts from SEER database were included. Cox regression was used to calculate the relative impacts between prognostic groups. The predictive accuracy of overall survival (OS) was assessed using the concordance index (C‐index), which was compared by likelihood ratio test. Results In FUSCC cohort, the 5‐year‐OS rate for T3N0M0 patients was higher than T1‐3N1M0 (72.7% vs 38.1%). The 5‐year‐OS rate for T4N0M0 was 36.2%, which was close to T1‐3N1M0 but not to T4N1M0 (0%) and TanyNanyM1 (12.6%). The elements of AJCC groups were regrouped according to the ranks of hazard ratios. The modified stages II (T3N0M0), III (T1‐3N1M0, T4N0M0), and IV (T4N1M0, TanyNanyM1) exhibited greater survival stratification than AJCC groups. The modifications were validated in SEER cohort and yielded similar survival outcomes. The predictive accuracy of OS in modified prognostic groups was significantly higher than AJCC groups in stages II‐IV subgroups in both FUSCC (C‐index: 0.801 vs 0.779, P < 0.001) and SEER cohort (C‐index: 0.770 vs 0.764, P < 0.001). Conclusions The modified AJCC prognostic groups for RCC provided significantly improved survival prediction compared with the 8th AJCC edition. A precise risk stratification of modified stages II‐IV disease provides an important basis for risk‐equivalent treatment recommendation.

Abstract
BACKGROUND Accumulated evidence suggests that metastatic prostate cancer (mPCa) with a low prostate-specific antigen (PSA) level may be a unique entity. However, its clinical features and prognosis have not been fully evaluated. OBJECTIVE To investigate the clinical features of low-PSA mPCa and the impact of low PSA level on overall survival (OS) and PCa-specific mortality (PCSM) of mPCa. DESIGN, SETTING, AND PARTICIPANTS A total of 8479 mPCa patients were retrieved from the Surveillance, Epidemiology, and End Results program (2010-2015). The median follow-up was 18 mo. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Cox regression and Fine-Gray competing risk were used to calculate the hazard ratio (HR) and subdistribution hazard ratio (sHR) for OS and PCSM, respectively. RESULTS AND LIMITATIONS A higher rate of T4 stage disease (19.8%) and visceral metastasis (18.2%) and the shortest median OS (34 mo) were observed in mPCa patients with Gleason 8-10 and PSA ≤4ng/ml. In the Cox regression model, PSA ≤4ng/ml was a significant predictor of OS for Gleason 8-10 disease. The distribution of PCSM by PSA was U-shaped for Gleason score 8-10 (PSA 4.1-10ng/ml as the referent), with an adjusted sHR of 1.52 for PSA ≤4.0ng/ml (95% confidence interval: 1.17-1.96) versus 0.99 for PSA 10.1-20ng/ml and 1.35 for PSA >20ng/ml. In contrast, the distribution of PCSM by PSA was linear for Gleason 5-7. Sensitivity analyses showed similar results in Gleason 9-10 and Gleason 10 subgroup. The study is limited by its retrospective design. CONCLUSIONS Low PSA, high-grade mPCa has a higher proportion of T4 stage disease, visceral metastasis, and PCSM. PATIENT SUMMARY We found that 2.8% of high-grade metastatic prostate cancer has a prostate-specific antigen level ≤4ng/ml at diagnosis. This population has aggressive clinical features and a poor cancer-specific outcome. Our results highlighted this under-reported population, and the management of these patients warrants further research.

Abstract
AIM To analyse the change in size on follow-up of hepatic adenomas (HAs) and adenomatosis, and to investigate the relationship of imaging features with size change. MATERIALS AND METHODS The study included 44 patients (142 lesions) who underwent magnetic resonance imaging (MRI) or computed tomography (CT) for diagnosis and follow-up of HA. The imaging features and percentage change in maximum tumour dimension were observed over a follow-up duration of up to 139 months. RESULTS With an average follow-up of 43 months, 37% lesions decreased in size, 58% were stable, 4% increased; one lesion regressed completely. Adenomas were stratified into size groups (<3, 3-5, and ≥5 cm). Size change among the three groups was similar (p>0.05). Percent size change was different for lesions followed for ≤12 months (-7.2%) compared with lesions followed for 13-60 months (-20.5%), and those followed for ≥60 months (-23.5%; p<0.05); there was no difference between lesions followed for 13-60 months and ≥60 months (p=0.523). Baseline size and percent size change was similar between the hepatocyte nuclear factor 1α-inactivated HA (HA-H) and inflammatory HA (HA-I) subtype (p>0.05). CONCLUSION Most adenomas were either stable or regressed on follow-up. Size change was independent of baseline size. After an initial size decrease within 5 years, no further size reduction was noted on extended follow-up. The percent size change in the HA-H and HA-I subtype was similar.

Abstract
A novel series of tricyclic tetrahydroquinolines were identified as potent and selective CRTh2 receptor antagonists. The agonism and antagonism switch was achieved through structure-based drug design (SBDD) using a CRTh2 receptor homologue model. The challenge of very low exposures in pharmacokinetic studies was overcome by exhaustive medicinal chemistry lead optimization through focused SAR studies on the tricyclic core. Further optimization resulted in the identification of the preclinical candidate 4-(cyclopropyl((3aS,9R,9aR)-7-fluoro-4-(4-(trifluoromethoxy)benzoyl)-2,3,3a,4,9,9a-hexahydro-1H-cyclopenta[b]quinolin-9-yl)amino)-4-oxobutanoic acid (15c, MK-8318) with potent and selective CRTh2 antagonist activity and a favorable PK profile suitable for once daily oral dosing for potential treatment of asthma.

Abstract
Retinal pericyte migration represents a novel mechanism of pericyte loss in diabetic retinopathy (DR), which plays a crucial role in the early impairment of the blood-retinal barrier (BRB). Glucagon-like peptide-1 (GLP-1) has been shown to protect the diabetic retina in the early stage of DR; however, the relationship between GLP-1 and retinal pericytes has not been discussed. In this study, advanced glycation end products (AGEs) significantly increased the migration of primary bovine retinal pericytes without influencing cell viability. AGEs also significantly enhanced phosphatidylinositol 3-kinase (PI3K)/Akt activation, and changed the expressions of migration-related proteins, including phosphorylated focal adhesion kinase (p-FAK), matrix metalloproteinase (MMP)-2 and vinculin. PI3K inhibition significantly attenuated the AGEs-induced migration of retinal pericytes and reversed the overexpression of MMP-2. Glucagon-like peptide-1 receptor (Glp1r) was expressed in retinal pericytes, and liraglutide, a GLP-1 analog, significantly attenuated the migration of pericytes by Glp1r and reversed the changes in p-Akt/Akt, p-FAK/FAK, vinculin and MMP-2 levels induced by AGEs, indicating that the protective effect of liraglutide was associated with the PI3K/Akt pathway. These results provided new insights into the mechanism underlying retinal pericyte migration. The early use of liraglutide exerts a potential bebefical effect on regulating pericyte migration, which might contribute to mechanisms that maintain the integrity of vascular barrier and delay the development of DR.

Abstract
BACKGROUND To investigate the effect of miR-221-5p on cell proliferaton and metastasis of human prostate cancer in vitro and vivo. METHODS We established PC3 cell lines with stable overexpression or silencing of miRNA-221-5p via lentivirus infection. miRNA-221-5p and its target gene SOCS1 expression levels in the stable cells were analyzed by real-time polymerase chain reaction (RT-PCR) and western blotting. Using luciferase reporter assays to study the relationship between miR-221-5p and SOCS1. Cell proliferative activity was measured using the MTT assay and colony formation assay. Migration ability was assessed using wound-healing assay and transwell assay. To further study the function of miR-221-5p in human prostate cancer we established nude mice xenograft model in vivo. RESULTS miR-221-5p regulates the proliferation, migration of prostate cancer cells in vitro and tumorigenesis in vivo by regulating socs1 expression through targeted its 3'UTR, and miR-221-5p regulates MAPK/ERK signaling pathway and EMT features in prostate cancer cells. CONCLUSIONS Up-regulation and silencing of miR-221-5p expression in prostate cancer cells are correlated with cell proliferation, migration and tumorigenesis, which suggest that miR-221-5p plays an important role in prostate cancer progression.

Abstract
MicroRNAs (miRNAs) are short, conserved segments of non-coding RNA which play a significant role in prostate cancer development and progression. To identify miRNAs associated with castration resistance, we performed miRNA microarray analysis comparing castration resistant prostate cancer (CRPC) with androgen dependent prostate cancer (ADPC). We identified common underexpression of miR-4638-5p in CRPC compared to ADPC samples, which were further confirmed by quantitative PCR analysis. The role of miR-4638-5p in prostate cancer androgen-independent growth has been demonstrated both in vitro and in vivo. We also identified Kidins220 as a target gene directly regulated by miR-4638-5p and shRNA-mediated knockdown of Kidins220 phenocopied miR-4638-5p restoration. Subsequently, we revealed that Kidins220 activates PI3K/AKT pathway, which plays a key role in CRPC. Loss of miR- 4638-5p may lead to CRPC through the activity of Kidins220 and PI3K/AKT pathway. Furthermore, we found that miR-4638-5p, through regulating Kidins220 and the downstream activity of VEGF and PI3K/AKT pathway, influences prostate cancer progression via angiogenesis. The identification of miR-4638-5p down-regulation in CRPC and the understanding of the functional role of miR-4638-5p and its downstream genes/pathways have the potential to develop biomarkers for CRPC onset and to identify novel targets for novel forms of treatments of this lethal form of PCa.

Abstract
Multi-target, short time, and resource-affordable methodologies for the detection of multiple nucleic acids in a single, easy to operate test are urgently needed in disease diagnosis, microbial monitoring, genetically modified organism (GMO) detection, and forensic analysis. We have previously described the platform called CALM (Capillary Array-based Loop-mediated isothermal amplification for Multiplex visual detection of nucleic acids). Herein, we describe improved fabrication and performance processes for this platform. Here, we apply a small, ready-to-use cassette assembled by capillary array for multiplex visual detection of nucleic acids. The capillary array is pre-treated into a hydrophobic and hydrophilic pattern before fixing loop-mediated isothermal amplification (LAMP) primer sets in capillaries. After assembly of the loading adaptor, LAMP reaction mixture is loaded and isolated into each capillary, due to capillary force by a single pipetting step. The LAMP reactions are performed in parallel in the capillaries. The results are visually read out by illumination with a hand-held UV flashlight. Using this platform, we demonstrate monitoring of 8 frequently appearing elements and genes in GMO samples with high specificity and sensitivity. In summary, the platform described herein is intended to facilitate the detection of multiple nucleic acids. We believe it will be widely applicable in fields where high-throughput nucleic acid analysis is required.

Abstract
There is an urgent demand for affordable, rapid and easy-to-use technology to simultaneously detect many different DNA targets within one reaction. Conventional multiplex PCR is an effective methodology to simultaneously amplify different DNA targets. However, its multiplicity is limited due to the intrinsic interference and competition among primer pairs within one tube. Here, we present an easy multiplex PCR microchip system, which can simultaneously detect 54 targets. The design of the microchip is quite simple. There is a microchannel connected with multiple underlying parallel microwells. And every microchannel has an inlet/outlet for loading PCRmix. The surface of the microchannel is hydrophobic and the inner surface of the microwell is hydrophilic, which enables us to load and separate the PCRmix into different microwells simultaneously. Different primer pairs and low melting agarose are pre-fixed in different microwells, and the microchip is assembled with top glass. The PCRmix is loaded into inlets and then mineral oil is sequentially pipetted into channels to push the PCRmix into all microwells and subsequently mineral oil fills the channels to avoid cross contaminations. After the PCRmix is loaded, it would be placed on a plat thermal cycler for PCR. During PCR, the low melting gel in the well is liquid and after PCR it would be solidified due to temperature changes. When PCR is completed, a nucleic acid dye is introduced into channels and then results are visualized by a home-made, potable UV detector. In our platform we successfully detected seven frequently used targets of genetically modified (GM) organisms. The results demonstrate that our platform has high flexibility and specificity. Due to the excellent performance of this technology, we believe that it can be applied to multiple nucleic acid detection fields including GM organisms.

Abstract
OBJECTIVE The metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA (lncRNA) that plays a key role in the malignant phenotype of tumors. Although abnormal regulation of lncRNA MALAT1 impacts clinical prognostic and tumor metastasis, its function remains unclear in ovarian cancer. PATIENTS AND METHODS We collected 64 samples of surgical EOC tissues and 30 samples of normal ovarian tissues at the Department of Gynecology of Harbin Medical University (Harbin, China). The 30 control samples of ovarian surface epithelial tissues were obtained from patients diagnosed with uterine fibroids and scheduled hysterectomy with oophorectomy. RESULTS The present study discovered that MALAT1 was upregulated in tumor tissues and ovarian cancer cell lines. Further, the 5-year overall survival was higher in the lower expression of the MALAT1 group. MALAT1 inhibition impeded cell proliferation, invasion and metastasis, and promoted cell apoptosis in both in vivo and in vitro. Furthermore, silencing of MALAT1 hindered the expression of epithelial-to-mesenchymal transition (EMT)-related genes and MMPS. The evidence showed that MALAT1 induce EMT via PI3K/AKT pathway. CONCLUSIONS Our research suggests that MALAT1 transforms metastasis in EOC and may be a prospective therapeutic target.

Abstract
Singlet oxygen (1 O2 ) signalling in plants is essential to trigger both acclimatory mechanisms and programmed cell death under high light stress. However, because of its chemical features, 1 O2 requires mediators, and the players involved in this pathway are largely unknown. The β-carotene oxidation product, β-cyclocitral, is one such mediator. Produced in the chloroplast, β-cyclocitral induces changes in nuclear gene expression leading to photoacclimation. Recently, the METHYLENE BLUE SENSITIVITY protein MBS has been identified as a key player in 1 O2 signalling leading to tolerance to high light. Here, we provide evidence that MBS1 is essential for acclimation to 1 O2 and cross-talks with β-cyclocitral to mediate transfer of the 1 O2 signal to the nucleus, leading to photoacclimation. The presented results position MBS1 downstream of β-cyclocitral in 1 O2 signalling and suggest an additional role for MBS1 in the regulation of plant growth and development under chronic 1 O2 production.

Abstract
There is an urgent need for rapid, low-cost multiplex methodologies for the monitoring of genetically modified organisms (GMOs). Here, we report a C[combining low line]apillary A[combining low line]rray-based L[combining low line]oop-mediated isothermal amplification for M[combining low line]ultiplex visual detection of nucleic acids (CALM) platform for the simple and rapid monitoring of GMOs. In CALM, loop-mediated isothermal amplification (LAMP) primer sets are pre-fixed to the inner surface of capillaries. The surface of the capillary array is hydrophobic while the capillaries are hydrophilic, enabling the simultaneous loading and separation of the LAMP reaction mixtures into each capillary by capillary forces. LAMP reactions in the capillaries are then performed in parallel, and the results are visually detected by illumination with a hand-held UV device. Using CALM, we successfully detected seven frequently used transgenic genes/elements and five plant endogenous reference genes with high specificity and sensitivity. Moreover, we found that measurements of real-world blind samples by CALM are consistent with results obtained by independent real-time PCRs. Thus, with an ability to detect multiple nucleic acids in a single easy-to-operate test, we believe that CALM will become a widely applied technology in GMO monitoring.

Abstract
BACKGROUNDS Compared to pure small cell lung cancer (SCLC), combined small cell lung cancer (C-SCLC) has its own characteristics. High neutrophil to lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been shown to be related to poor prognosis in several types of tumors. The aim of this study was to explore the prognosis value of NLR and PLR in patients with C-SCLC. METHODS A total of 112 patients diagnosed with C-SCLC between January 2000 and March 2009 were enrolled in the study. The clinicopathological parameters, laboratory analyses, and survival time were collected and analyzed. The correlation between NLR, PLR, and clinicopathological characters was analyzed. Univariate and multivariate analyses were performed to investigate the prognostic significance of these parameters for C-SCLC. RESULTS The pretreatment NLR was elevated in 37.5 % patients (NLR ≥ 4.15; n = 42; H-NLR). NLR was significantly related to disease stage (p = 0.033) and tumor recurrence (p = 0.014). The median overall survival (OS) and progression-free survival (PFS) were significantly worse in the H-NLR group (OS: 22.0 months vs 11.7 months, p = 0.001; PFS: 11.1 vs 6.0 months, p < 0.001). However, PLR at diagnosis was not associated with OS or PFS. Multivariate analyses indicated elevated NLR (HR = 1.6; p = 0.001), disease stage (HR = 1.6; p = 0.001), and performance status (HR = 1.8; p = 0.015) as independent prognostic factors. CONCLUSIONS High pretreatment NLR (≥4.15) is a potential useful indicator for C-SCLC recurrence and predicts a poor long-term prognosis for C-SCLC, which should be considered in defining the prognosis with other well-known prognosticators in C-SCLC patients.

Abstract
BACKGROUND/AIMS Primary glomerulonephritis (PGN) is the most common reason inducing end stage renal disease in China, however, its pathogenesis remains unclear. The present study was designed to test the hypothesis that the formation and activation of NLRP3 (Nod-like receptor family pyrin domain containing 3) inflammasomes is an important initiating mechanism resulting in PGN. METHODS Serum samples and frozen sections were collected from 38 cases with PGN, and renal tissues were obtained from 22 of them. NLRP3 inflammasomes were detected by RT-PCR and immunofluoresence methods. The relationship between NLRP3 and clinical/pathologic indexes was analyzed. RESULTS RT-PCR analyses demonstrated that the mRNA levels of NLRP3 and caspase-1 genes were elevated significantly in renal tissues of PGN patients compared to those from normal pericarcinoma tissues. Moreover, the increased level of NLRP3 mRNA was correlative with a decrease in nephrin mRNA level and an increase in desmin mRNA level, which indicates that NLRP3 participates in podocyte injury in PGN patients. Immunofluorescence analysis also showed the protein expressions of NLRP3 and caspase-1 were increased in the glomeruli of PGN patients. Neverthless, there was no obvious regularity was presented in further subgroup analysis according to pathological types. In addition, increased NLRP3 was associated with the deterioration of renal function and glomerulosclerosis. IL-1β, a product of NLRP3 inflammasome activation, had a significant correlation with proteinuria. CONCLUSIONS The formation and activation of NLRP3 inflammasomes in podocytes has been importantly implicated in the development of PGN-associated glomerular injury.

Abstract
Extramammary Paget's disease (EMPD) is a special type of cancers. The etiology of the disease is still unclear. We aimed to study the expression differences of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in EMPD tissues and corresponding adjacent normal tissues. The mRNA expression was detected by RT-PCR and the protein expression was explored by immunohistochemistry. Higher immunostaining signal scores of bFGF and VEGF in EMPD tissues had been found (z=-3.827, P<0.001, z=-3.729, P<0.001, respectively). In addition, the mRNA expression of bFGF and VEGF was higher in EMPD tissues, which had been validated by RT-PCR (t=5.771, P<0.001, t=3.304, P=0.004, respectively). The VEGF and bFGF might be the key signaling proteins in angiogenesis of EMPD. How to block the VEGF and bFGF in EMPD and to destroy the blood supply of the tumor cells becomes the focus of our future research.

Abstract
BACKGROUND Diabetic retinopathy (DR) is a leading cause of acquired blindness in adults. Previous research has shown that the apoptosis of retinal ganglion cells(RGCs) plays an important role in the initiation and development of diabetic retinopathy. The positive effect of estrogen on the nervous system is currently attracting increasing attention. In this study, we investigated whether17β-estradiolum (E2) has protective effects on RGCs in a high-glucose environment. METHODS The cell survival rates were measured by Cell Counting Kit-8, the apoptosis was detected by flow cytometry, the intracellular reactive oxygen species (ROS) levels were examined by immunofluorescence method, and the intracellular mitochondrial membrane potential was examined by confocal microscopy. The expression levels of cytochrome C, Bcl-2, and Bax were analyzed by Western blot method. The effect of estrogen receptor blocker tamoxifen on the RGCs was also evaluated. RESULTS It was found that E2 stabilizes the mitochondrial membrane potential, reduces intracellular ROS levels, up-regulates Bcl-2 expression, inhibits Bax expression, decreases the generation of cytochrome C, and finally reduces the apoptosis of RGC-5 cells in a high-glucose environment. These protective functions could be attributed to E2 receptors, which make E2 a prospective patent application candidate in the treatment of DR. Furthermore, when cells were pre-cultured with tamoxifen, we found that tamoxifen inhibited the shielding effects of E2. CONCLUSION E2 has a broad application prospect in the treatment of DR.

Abstract
BACKGROUND The purpose of this study was to evaluate the advantages of exenatide treatment on obesity and non-alcoholic fatty liver disease (NAFLD) with elevated liver enzymes in patients with type 2 diabetes (T2D). METHODS A total of 60 newly diagnosed patients with obesity, NAFLD with elevated liver enzymes and T2D were included in the study. The patients were randomly divided into two groups. The exenatide treatment group (n = 30) were treated with exenatide and insulin glargine, and the intensive insulin therapy group (n = 30) were treated with insulin aspart and insulin glargine for 12 weeks. Selected clinical characteristics were determined, and ultrasonography was performed at both baseline and 12 weeks following treatment. RESULTS At baseline, the clinical characteristics were matched between the two groups. After 12 weeks, fasting blood glucose (FBG), postprandial blood glucose (PBG), glycosylated haemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG) and total bilirubin levels were significantly decreased in the two groups (p < 0.001). Body weight and waist circumference were significantly decreased in the exenatide group but increased in the intensive insulin group (p < 0.001). The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyl transpeptidase (γGGT) in the exenatide group were significantly lower than in the intensive insulin group (p < 0.001). The mean body weight change correlated with the levels of ALT, AST and γGGT change (ALT, r = 0.761; AST, r = 0.733; γGGT, r = 0.752; p < 0.001). Moreover, the reversal rate of fatty liver was significantly higher in the exenatide group (93.3%) than the intensive insulin group (66.7%) (p < 0.01). CONCLUSIONS Exenatide has a better hepatic-protective effect than intensive insulin therapy and perhaps represents a unique option for adjunctive therapy for patients with obesity, non-alcoholic fatty liver disease with elevated liver enzymes and T2D.

Abstract
The unicellular green algae Chlamydomonas reinhardtii is a classic model for the study of flagella/cilia and photosynthesis, and it has recently been exploited for producing biopharmaceuticals and biofuel. Due to the low frequency of homologous recombination, reverse genetic manipulation in Chlamydomonas relies mainly on miRNA- and siRNA-based knockdown methods. However, the difficulty in constructing artificial miRNA vectors, laborious screening of knockdown transformants, and undesired epigenetic silencing of exogenous miRNA constructs limit their application. We have established a one-step procedure to construct an artificial miRNA precursor by annealing eight oligonucleotides of approximately 40 nucleotides. In the final construct, the Gaussia princeps luciferase gene (G-Luc) is positioned between the promoter and the artificial miRNA precursor so that knockdown strains may quickly be screened by visualizing luciferase luminescence using a photon-counting camera. Furthermore, the luciferase activity of transformants correlates with the knockdown level of two test target proteins: the chloroplast protein VIPP1 (vesicle inducing protein in plastids 1) and the flagellar protein CDPK3 (calcium-dependent protein kinase 3). Adding an intron from RBCS2 (ribulose bisphosphate carboxylase/oxygenase small subunit 2) to the miRNA construct enhanced both the luciferase activity and the miRNA knockdown efficiency. A second miRNA vector incorporated the promoter of the nitrate reductase gene to allow inducible expression of the artificial miRNA. These vectors will facilitate application of the artificial miRNA and provide tools for studying the mechanism of epigenetics in Chlamydomonas, and may also be adapted for use in other model organisms.

Abstract
Several genes encoding DNA repair molecules have been proposed as cancer-susceptibility genes. Many studies have suggested that SNPs in XRCC4 could be implicated in altering the risk of prostate cancer (PCa). We examined the role of the functional variant (-652T>G) in the XRCC4 promoter in PCa. The transcriptional activity of XRCC4 gene was measured by luciferase assay. We performed real-time PCR/immunohistochemical assay to verify the association between expression level of XRCC4 mRNA/protein and XRCC4 -652T>G polymorphism. In addition, electrophoretic mobility shift assay (EMSA) was used to confirm whether this polymorphism has an effect on binding ability of the transcription factor. We found that the G variant significantly increased the transcription activity of the XRCC4 gene and the binding ability of transcriptional factor GATA-1 to the XRCC4 promoter. Furthermore, the results suggested that the XRCC4 protein and mRNA were overexpressed in individuals who carried the -652G allele compared to carriers of the -652T allele. In addition, the expression of XRCC4 in PCa tissues was lower than in adjacent normal tissues. Our data suggest that the XRCC4 promoter -652G>T polymorphism is functional and may influence genetic susceptibility to prostate cancer. Case-control studies are required to validate our findings in the future.

Abstract
Acute aortic dissection (AAD) is a life threatening cardiovascular medical emergency with a poor prognosis. To explore the utility of D-dimers (DD) in the diagnosis of AAD, we performed a prospective study and conducted a meta-analysis of previous studies. 368 suspected patients were enrolled, including AAD n = 89, PE n = 12, AMI n = 167, normal controls n = 100. All patients had a DD test immediately after admission. We then performed a comprehensive computer search to identify studies investigating using DD as a screening tool for AAD. Finally, we pooled these data to estimate sensitivity, specificity, positive and negative likelihood ratios (LRs) by using DerSimonian-Laird random-effects models. The DD concentrations in the AAD group were significantly higher than those in the AMI and normal control groups. However, the DD level of 500 ng/ml had a poor sensitivity of 51.7 % and specificity of 89.2 % in the diagnosis of AAD. Subgroup analyses found that DD only showed a well discriminative ability of distinguishing AAD patients from normal controls (specificity and positive LR was 97 % and 17.2, respectively). The pooled sensitivity, specificity, positive and negative LR in our meta-analysis was 89, 68 %, 2.71, 0.07, respectively. In conclusion, our results suggest that plasma DD levels cannot add to the certainty of AAD diagnosis and it is not a good biomarker for AAD. In the future, prospective research on patients from many parts of the world is warranted to validate our findings. In addition, different controls, methods of plasma DD assays and other factors should be considered.

Abstract
Isoxazoles are frequently used amide isosteres, as shown in the context of discovery of CRTh2 antagonists from amide 1 to isoxazole 2. However, persistent agonism and poor solubility in isoxazole series presented challenges to its further development. Based on the concept of quality by design (QbD), 5,5-disubstituted isoxazolines 3 were introduced. The chirality at 5 position of isoxazolines controlled the switch between two modes of actions, which led to a novel series of pure antagonists. This non-planar motif also conferred a change of shape of these molecules, which avoided flat structures and improved their physical properties.

Abstract
The monitoring of genetically modified organisms (GMOs) is a primary step of GMO regulation. However, there is presently a lack of effective and high-throughput methodologies for specifically and sensitively monitoring most of the commercialized GMOs. Herein, we developed a multiplex amplification on a chip with readout on an oligo microarray (MACRO) system specifically for convenient GMO monitoring. This system is composed of a microchip for multiplex amplification and an oligo microarray for the readout of multiple amplicons, containing a total of 91 targets (18 universal elements, 20 exogenous genes, 45 events, and 8 endogenous reference genes) that covers 97.1% of all GM events that have been commercialized up to 2012. We demonstrate that the specificity of MACRO is ~100%, with a limit of detection (LOD) that is suitable for real-world applications. Moreover, the results obtained of simulated complex samples and blind samples with MACRO were 100% consistent with expectations and the results of independently performed real-time PCRs, respectively. Thus, we believe MACRO is the first system that can be applied for effectively monitoring the majority of the commercialized GMOs in a single test.

Abstract
OBJECTIVE Recently, novel endothelins like zibotentan and atrasentan and other novel taxanes have been introduced to treat prostate cancer. This study reviews zibotentan in the treatment of castration-resistant prostate cancer (CRPC) and derives a more precise estimate of their effect of treatment. MATERIALS AND METHODS Two reviewers searched and extracted data of the published trials and review articles on zibotentan for prostate cancer using the Medline, Embase and Cochrane Controlled Trials Register database. We used hazard ratios (HRs) to assess the effects on overall survival (OS), progression-free survival (PFS), or time to PSA progression (TTP), and relative risk (RR) for the different types of toxicity. Four randomized controlled trials were identified. RESULTS The pooled HR showed that zibotentan did not improve OS and PFS (HR = 0.92, 95%CI = 0.82-1.03, p = 0.161, HR = 0.98, 95% CI = 0.89-1.08, p = 0.714). Zibotentan had modest benefits on TTP (HR = 0.94, 95% CI = 0.91-0.97, p = 0.001). In addition, zibotentan led to more peripheral edema, anemia, cardiac failure and pneumonia. CONCLUSIONS Our study concludes that zibotentan is not an attractive option for CRPC patients. However, additional studies on other novel therapies are needed to improve patient outcomes.

Abstract
OBJECTIVE To investigate the clinical characteristics and surgical treatment of penile Paget's disease. METHODS We retrospectively analyzed the treatment and follow-up data of 10 cases of penile Paget's disease surgically treated in Jiangsu Provincial Government Hospital and Jiangsu Provincial People's Hospital from 2008 to 2012. RESULTS All the 10 patients received expanded local resection of the lesion with reconstruction of the defects with scrotal skin flaps or free skin flaps from the thigh. All surgeries were successful and the postoperative course was uneventful with complete graft survival and no lymph node metastasis. IIEF scores obtained before and 1 -2 months after surgery showed no statistically significant differences in the penile erectile function (P = 0.229), sexual orgasm (P = 0.761), and sexual satisfaction (P = 0.801) of the patients. CONCLUSION When penile skin lesions suggest the possibility of Paget's disease, biopsy should be performed and surgery should follow as soon as possible. The ideal surgical option is expanded local resection of the lesion with reconstruction of the defects with scrotal skin flaps or free flaps according to the patient's specific conditions.

Abstract
OBJECTIVE To explore the long-term survival and prognosis of prostate cancer patients after treated by androgen deprivation therapy. METHODS We conducted a follow-up study of 124 patients with prostate cancer treated by androgen deprivation therapy, and compared the survival times of the patients with different pathological grades and clinical characteristics using Kaplan-Meiers survival curves. RESULTS The mean survival time of the 124 patients after androgen deprivation therapy was 5. 912 years, with the median survival time of 7.81 years. The patients with bone metastases showed a shorter survival time than those with non-bone metastasis (P = 0.04). Pathological grades and PSA levels were not prognostic factors. No significant differences were found in the mean survival time between those died of prostate cancer (n = 35) and those from other factors (n = 23) (P = 0.50). CONCLUSION Bone metastasis is an important prognostic factor in advanced prostate cancer following androgen deprivation therapy, which is more significantly correlated with the survival time of the patients than tumor grades and clinical classification.

Abstract
All cells produce reactive oxygen species (ROS) as by-products of their metabolism. In addition to being cytotoxic, ROS act as regulators of a wide range of developmental and physiological processes. Little is known about the molecular mechanisms underlying the perception of ROS and initiation of cellular responses in eukaryotes. Using the unicellular green alga Chlamydomonas reinhardtii, we developed a genetic screen for early components of singlet oxygen signaling. Here, we report the identification of a small zinc finger protein, methylene blue sensitivity (MBS), that is required for induction of singlet oxygen-dependent gene expression and, upon oxidative stress, accumulates in distinct granules in the cytosol. Loss-of-function mbs mutants produce singlet oxygen but are unable to fully respond to it at the level of gene expression. Knockout or knockdown of the homologous genes in the higher plant model Arabidopsis thaliana results in mutants that are hypersensitive to photooxidative stress, whereas overexpression produces plants with elevated stress tolerance. Together, our data indicate an important and evolutionarily conserved role of the MBS protein in ROS signaling and provide a strategy for engineering stress-tolerant plants.

Abstract
OBJECTIVE Evidence is accumulating that several genes encoding DNA repair molecules may be cancer-susceptibility genes. Recently, SNPs in XRCC4, a member of DNA repair genes, have been implicated in altering the risk of various cancers. However, the results of these studies are inconclusive or controversial. To derive a more precise estimation, we performed an updated meta-analysis. METHODS A comprehensive search was conducted to examine all the eligible studies about XRCC4 polymorphism and cancer risk. We used odds ratios (ORs) with 95% confidence intervals (CIs) to assess the strength of the association. RESULTS We included 31 studies investigated 8 SNPs in XRCC4. Overall, our paper showed significant associations between the rs28360071, rs2075686 polymorphisms and cancer risk. In addition, significant association was maintained in prostate cancer (rs28360071), lung cancer (rs6869366) and bladder cancer (rs1805377) subgroups analysis. CONCLUSIONS We conducted a systematic search and combined the available results in this meta-analysis, which provided evidence of the associations between SNPs in XRCC4 and cancer risk. The results suggested that rs28360071 polymorphisms were significantly associated with cancer risk. However, future studies are needed to investigate molecular mechanisms underlying the biological functions of XRCC4 SNPs in cancer development.

Abstract
Recently, novel therapies of prostate cancer, such as immunotherapy, endothelin receptor antagonists, novel androgen receptor antagonist and novel taxanes, and others have been introduced into clinical practice. This study was performed to summarize these results of immunotherapy and endothelin receptor antagonists in the treatment of castration-resistant prostate cancer (CRPC) and derive a more precise estimation of their effect on future treatment. The PubMed database, references of published trials, and review articles were searched. Two reviewers independently extracted data of these trials. We used hazard ratios (HRs) to assess the effects on overall survival (OS), progression-free survival (PFS), or time to disease progression (TTP), and relative risk (RR) for the different types of toxicity. In addition, 95% confidence intervals (CIs) give a sense of the precision of the estimate. Nine randomized controlled trials were ultimately identified. The pooled HR showed that immunotherapy could prolong OS significantly in patients with CRPC compared to placebo (HR = 0.70, 95% CI: 0.58-0.83, p < 0.001). Endothelin receptor antagonists also had modest benefits (HR = 0.90, 95% CI: 0.82-1.00, p = 0.046). Nevertheless, there were no significant benefits from both therapies on PFS or TTP. In addition, immunotherapy led to more fatigue, pyrexia, chills, and endothelin receptor antagonists led to more peripheral edema, anemia, and dyspnea. Our article suggested that the very acceptable toxicity and improving OS in patients with CRPC made immunotherapy an attractive option for such patients. However, future studies with thoughtful clinical trial designs are warranted.

Abstract
The tumor suppressor gene p53 appears to be important in the development of many human cancers, such as prostate cancer. The association of p53 codon72 polymorphism with prostate cancer has been widely reported; however, the results are inconsistent. To derive a more precise estimation of this relationship, we performed an updated meta-analysis from 10 case-control studies. We conducted a search in the PubMed database without a language limitation, covering all papers published until July 2010. Risk ratios (RR) with 95% confidence intervals(CIs) were used to assess the strength of the association. Ten studies including 1,196 cases and 1,704 controls were selected. Overall, no significant differences of total prostate cancer risk and p53 codon polymorphism was found (Pro/Pro vs Arg/Arg, RR = 1.12, 95%CI=0.74-1.70, Pheterogeneity = 0.016, I2 = 55.8%; Pro/Pro+Pro/Arg vs Arg/Arg, RR = 1.05, 95%CI=1.00-1.11, Pheterogeneity = 0.077, I2 = 51.1%). In the stratified analysis by ethnicity, the same results were found. However, in the control subgroup, there was a modest decreased association between prostate cancer risk and population-based control subjects under the recessive genetic model (RR = 0.31, 95%CI=0.10-0.91, Pheterogeneity = 0.110, I2 =60.8%). This meta-analysis suggested that p53 codon Pro72Arg polymorphism could be weakly associated with prostate cancer risk.

Abstract
A wide range of microalbuminuria cutoff values are currently used for diagnosing the early stage of nephropathy in type 2 diabetes (T2D). This study analyzed the relationships between oxidant and antioxidant markers of nephropathy and the severity of microalbuminuria. The study included 50 healthy controls (Group 1), 50 diabetic patients with no nephropathy (Group 2), 50 diabetic patients with nephropathy and a urinary albumin excretion (UAE) of 30-200 mg/24 h (Group 3), and 50 diabetic patients with UAE 200-300 mg/24 h (Group 4). Serum nitrotyrosine, conjugated dienes, 8-hydroxy-2'-deoxyguanosine (8-OHdG), superoxide dismutase (SOD), and total antioxidant capacity (T-AOC) levels were determined. Oxidative stress is increased in the early stage of nephropathy in patients with T2D. There was a significant correlation between the extent of microalbuminuria and markers of oxidative stress. Multiple linear regression analysis identified lipid oxidative stress as a possible independent marker for evaluating the degree of renal damage in diabetic nephropathy. Stratifying microalbuminuria values during the early stage of nephropathy might be an important factor in facilitating earlier and more specific interventions.

Abstract
MicroRNAs (miRNAs) are endogenously expressed small non-coding RNAs, which are evolutionarily conserved and function as regulators of gene expression. These molecules are involved in numerous biological processes including differentiation, development, proliferation and apoptosis. Further investigation identifies that miRNAs may act as either potent oncogenes or tumor-suppressor genes, linking to cancer initiation and progression. Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL), as a member of the TNF family, is an attractive therapeutic target in cancer because it directly induces tumor cell apoptosis and has no cytotoxicity to normal cell types in vitro or in vivo. However, the resistance to TRAIL-induced apoptosis limits its clinical effectiveness. Interestingly, several studies convincingly demonstrate a role of miRNAs in modulating sensitive/resistant phenotypes to TRAIL. Here, we review the current findings about miRNAs involved in TRAIL-induced apoptosis in different cancers.
