Abstract
OBJECTIVE To identify the validity and predictability of the confusion assessment method for the intensive care unit (CAM-ICU) for delirium in critically ill patients in the ICU. METHODS In this systematic review, PubMed, Embase, Cochrane Central Register of Controlled Trials, and MEDLINE databases were searched for observational studies investigating delirium screening tools for ICU patients. In the meta-analysis, we combined the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic odds ratio, and area under the curve (AUC) of SROC to analysis the predictive value of CAM-ICU. RESULTS Twenty-nine articles met the inclusion criteria. The pooled sensitivity and specificity values were 0.82 (95% confidence interval [CI]: 0.75-0.87) and 0.95 (95% CI: 0.93-0.97), respectively. The AUC point estimate of the SROC curve was 0.96 (95% CI: 0.94-0.97). Race (Asian or Others) could affect the pooled sensitivity and specificity, and the analysis method (Patient- or Scan-based) and study design were not sources of heterogeneity for pooled sensitivity and specificity. CONCLUSIONS The CAM-ICU is a valid and reliable tool for delirium prediction among ICU patients. When introducing CAM-ICU to assess delirium, it is necessary to localize its language and content to improve its predictive efficacy in different countries and different ethnic groups. RELEVANCE TO CLINICAL PRACTICE In clinical practice, nurses can use CAM-ICU to evaluate delirium in critically ill patients in ICU. However, it is necessary to debug the language and content according to the application population.

Abstract
OBJECTIVE This systematic review aimed to identify the prevalence of anxiety and depression in cardiac arrest (CA) survivors. METHODS A systematic review and network meta-analysis was performed on observational studies in adult cardiac arrest survivors with psychiatric disorders from PubMed, Embase, Cochrane Library and Web of Science. In the meta-analysis, we combined the prevalence quantitatively and analyzed the subgroup based on the classification indexes. RESULTS We identified 32 articles that met the inclusion criteria. Regarding anxiety,the pooled prevalence was 24% (95% CI, 17-31%) and 22% (95% CI, 13-26%) in short-term and long-term respectively. The subgroup analysis showed that the pooled incidence in in-hospital cardiac arrest (IHCA) and out-of-hospital cardiac arrests (OHCA) survivors was 14.0% (95%CI, 9.0-20.0%) and 28.0% (95%CI, 20.0-36.0%) for short-term anxiety.The incidence of anxiety measured by, Hamilton Anxiety Rating Scale(HAM-A) and State-Trait Anxiety Inventory(STAI) was higher than other tools(P < 0.01). Regarding depression,the data analysis showed that the pooled incidence of short-term and long-term depression was 19% (95% CI, 13-26%) and 19% (95% CI, 16-25%), respectively. The subgroup analysis showed that the incidence of short-term and long-term depression was 8% (95% CI, 1-19%) and 30% (95% CI, 5-64%) for IHCA survivors, and was 18% (95% CI, 11-26%) and 17% (95% CI, 11-25%) for OHCA survivors. The incidence of depression measured by Hamilton Depression Rating Scale(HDRS) and Symptom check list-90(SCL-90) was higher than other assessment tools(P < 0.01). CONCLUSIONS The meta-analysis indicated a high prevalence of anxiety and depression in CA survivors, and those symptoms persisted 1 year or more after CA. Evaluation tool is an important factor affecting the measurement results.

Abstract
The aim of the present study was to elucidate the evolutionary trajectory of colon cells from normal colon mucosa, to adenoma, then to carcinoma in the same microenvironment. Normal colon, adenoma and carcinoma tissues from the same patient were analyzed by single-cell sequencing, which perfectly simulated the process of time-dependent colon cancer due to the same microenvironment. A total of 22 cell types were identified. Results suggest the presence of dominant clones of same cells including C2 goblet cell, epithelial cell subtype 1 (Epi1), enterocyte cell subset 0 (Entero0), and Entero5 in carcinoma. Epi1 and Entero0 were Co-enriched in antibacterial and IL-17 signaling, Entero5 was enriched in immune response and mucin-type O-glycan biosynthesis. We discovered new colon cancer related genes including AC007952.4, NEK8, CHRM3, ANO7, B3GNT6, NEURL1, ODC1 and KCNMA1. The function of TBC1D4, LTB, C2CD4A, AND GBP4/5 in T cells needs to be clarified. We used colon samples from the same person, which provide new information for colon cancer therapy.

Abstract
As a marker of hypercoagulability, plasma D-dimer is associated with progression of many cancers but remains controversial in gastric cancer (GC). We aim to investigate the predictive value of D-dimer for postoperative outcomes after radical gastrectomy of GC patients. We enrolled 903 consecutive patients with GC who underwent radical gastrectomy and the clinicopathological characteristics were compared. Risk factors for overall survival (OS) and disease-free survival (DFS) were determined using multivariate cox regression analysis. We also compared the survival difference based on Kaplan-Meier method after a one-to-one propensity score matching (PSM). Patients with elevated D-dimer had older age (p < 0.001), advanced TNM stage (p < 0.001), larger tumor size (p = 0.005), lower 5-year OS rate (32.8% vs 62.6%, p < 0.001) and DFS (29% vs 59.6%, p < 0.001). In multivariate analysis, elevated D-dimer was independently associated with shorter OS [hazard ratio (HR): 1.633, 95% confidence interval (CI) 1.178-2.264, p = 0.003] and DFS (HR: 1.58, 95% CI 1.151-2.169, P = 0.005). After PSM, the 5-year OS rate of patients with elevated D-dimer was still significantly lower than matched group (32.8% vs 40.6%, p = 0.005), so was DFS (29% vs 36.6%, p = 0.008). Preoperative elevated D-dimer is an independent risk factor for GC patients undergoing curative gastrectomy.

Abstract
INTRODUCTION Essential hypertension is a major preventable risk factor for early cardiovascular disease, premature death and disability. It has been reported that telemedicine interventions can provide an innovative solution to essential hypertension to overcome the barriers that exist in traditional treatment or control. Nevertheless, this subject has not been thoroughly investigated. The goal of this study is to systematically evaluate and describe the impact of telemedicine interventions on essential hypertension. METHODS AND ANALYSIS To find relevant research, we will conduct a systematic literature search of three databases (PubMed, Embase and Cochrane Library), with no language limitations, in addition to researching grey literature. Two reviewers will extract the data individually, and any disagreements will be resolved by discussion or by a third reviewer. The randomised controlled trials will be chosen based on predetermined inclusion criteria. Primary outcomes will include systolic blood pressure and diastolic blood pressure after the telemedicine intervention. Secondary outcomes will include medication adherence (eg, the Morisky Medication Adherence Questionnaire), quality of life (eg, the MOS item scale of the Health Survey Short Form 36 questionnaire), blood pressure control rate and adverse events (eg, stroke, chronic renal failure, aortic dissection, myocardial infarction and heart failure). The quality of the included studies will be assessed using the Cochrane risk-of-bias method. The data will be analysed using RevMan V.5.3.5 software and STATA V.16.0 software. If heterogeneity testing reveals little or no statistical heterogeneity, a fixed effect model will be used for data synthesis; otherwise, a random effect model would be employed. We will synthesise the available evidence to perform a high-quality meta-analysis. ETHICS AND DISSEMINATION This project does not require ethical approval because it will be conducted using publicly available documents. The review's findings will be published in peer-reviewed journals and publications. PROSPERO REGISTRATION NUMBER CRD42021293539.

Abstract
As a systemic inflammatory marker, the significance of NLR in predicting tumor prognosis and early lymph node metastasis is well known, including gastric cancer (GC). However, whether NLR can reflect GC metastasis status remains to be explored. We retrospectively enrolled 1667 GC patients treated in our hospital from December 2010 to December 2018. Patients were grouped according to the presence or absence of metastases. Receiver operating characteristics (ROC) curve analysis was used to evaluate the diagnostic efficacy of markers in assessing GC metastasis. Then we conducted a joint ROC curve analysis. The effects of clinicopathological parameters on GC metastasis were assessed using multiple logistic regression analysis. 743 (44.6%) patients were diagnosed with metastatic GC. Patients with GC metastases have younger age, higher CEA, CA19-9, CA72-4 and NLR. Based on the comparison of AUC, NLR has diagnostic efficacy comparable to that of GC markers. The AUC of NLR combined with GC markers had significantly higher predicting efficacy than that without combination for assessing peritoneal metastasis (P = 0.013), osseous metastasis (P = 0.017) and hepatic metastasis (P < 0.001). In multiple logistic regression analysis, age, NLR, CEA, CA19-9 and CA72-4 were found to be independently associated with GC metastasis (all P < 0.05). NLR was a risk factor of GC metastasis. Combining CEA, CA19-9, CA72-4 and NLR could better predict metastases in GC.

Abstract
Tumor metastasis is closely related to the coagulation system. Tumor metastasis and hypercoagulability promote each other through multiple mechanisms. However, whether coagulation indicators can reflect tumor metastasis remains to be explored. Clinical characteristics of a total of 3447 patients from three tertiary referral centers were collected. Then the diagnostic efficacy of FDP, D-dimer and GC tumor markers [Carcinoembryonic antigen (CEA), Carbohydrate antigen 19-9 (CA19-9) and Carbohydrate antigen 72-4 (CA72-4)] for GC metastases was evaluated by the receiver operating characteristic curve (ROC) analyses. Then we conducted a joint ROC curve analysis. The effects of coagulation parameters and tumor markers on gastric cancer metastasis were assessed using multiple logistic regression analysis. 2049 patients were diagnosed with primary GC, 1398 patients with metastatic GC. Based on comparison of AUC, FDP (cutoff, 1.915) had significantly higher diagnostic efficacy than fibrinogen (P<0.001), CEA (P<0.001), CA199 (P<0.001) and CA724 (P<0.001). No significant difference was observed between D-dimer (cutoff, 0.905) and FDP (P=0.158). The AUC of tumor markers combined with coagulation indexes was higher than that without combination (P<0.001). In multiple logistic regression analysis, age, smoking, D-dimer, FDP, CEA, CA19-9, CA72-4 were found to be significantly associated with GC metastasis (all P<0.001, except for smoking P=0.004). We conclude that plasma FDP and D-dimer may be novel clinical biomarkers for screening metastases of GC.

Abstract
Background This study aimed to determine the factors that were related to the psychological health status of healthcare workers aid for Hubei after the COVID-19 outbreak. Methods A total of 1260 participants completed the Self-Rating Scale of Sleep (SRSS), the Generalized Anxiety Scale (GAD-7), and the 9-item patient health questionnaire (PHQ-9) via the online questionnaires, and their related experiences with COVID-19 were collected. Results The average SRSS score of all participants (25.13 ± 6.41) indicated a mild sleep problem, and the factors that influenced their sleep were the respondent’s gender, whether they had patients who died under their care, their history of psychosis and whether their family members were infected with COVID-19. The average GAD-7 score of all participants (12.37 ± 4.89) indicated a moderate anxiety level. The main factors that influenced anxiety were the respondent’s gender, years of work, history of psychosis, self-perceived health status, and whether their family members were infected with COVID-19. The average PHQ-9 score of all participants (8.90 ± 5.42) indicated a mild depression level. The primary factors that influenced depression were whether the respondent had nursed/treated severely ill patients in Hubei and whether they had a history of psychosis. Conclusions During the outbreak of COVID-19, the symptoms of anxiety were prominent among healthcare workers in Hubei. Moreover, male workers, those whose patients died during treatment, those with a history of anxiety disorders and those whose family members were infected with COVID-19 reported more serious problems. Therefore, this particular group of healthcare workers needs to be monitored and provided with tailored psychological support.

Abstract
FOXI1 plays a key role in the development of gastric cancer. However, the whole genome FOXI1 binding sites and its target genes are unclear. In the present study, we used ChIP-seq and RNA-seq technologies to identify the target gene of FOXI1. Firstly, ChIP-seq data showed that, 4476 unique peaks in the genome region were captured. Most of these binding peaks are located in introns or intergenic regions. We annotated all the peaks to the nearest gene and identified 404 genes as FOXI1 binding genes. KEGG and GO analysis showed that FOXI1 binding gene to be correlated with the cellular process, cell part, cell, binding, single-organism process. Further, we performed FOXI1-overexpressed RNA-seq experiment. We comprehensively analyzed the ChIP-seq and RNA-seq data and take the intersection of two databases, several genes were identified. ATF3 was selected from the intersection since ATF3 was the most enriched mRNA after FOXI1 overexpressed. ChIP-qPCR and luciferase report gene were used to validate that ATF3 was target gene of FOXI1. Intriguely, ATF3 protein was significantly downregulated after FOXI1 overexpressed. We found FOXI1 can also bind to the promoter of miR-590 and active it which directly target ATF3. The binding site between FOXI1 and miR-590 was verified by ChIP-qPCR and luciferase report gene, and the target relationship between miR-590 and ATF3 was confirmed by dual-luciferase reporter gene. In conclusion, our data identified the genome binding sites of FOXI1, and provide evidence that FOXI1 inhibits gastric cancer cell proliferation by activating miR-590/ATF3 axis.

Abstract
Breast cancer is the most common malignant tumor in women. Its incidence is associated with obesity and metabolic syndrome (MetS), which are highly prevalent world widely and have been identified as poorer prognosis factors in breast cancer including triple-negative breast cancer (TNBC), which has poorer response to chemotherapy, radiotherapy, and endocrine therapy. Programmed death ligand 1 (PD-L1) is one of the immune checkpoints ligands that facilitates tumor escape and progress. Obesity/MetS could cause systemic inflammation and immune disorders, however, whether and how obesity/MetS affect PD-L1 expression in breast cancer had not been clarified. In the present study, we examined the PD-L1 expression profile in breast cancer either in online database or cell lines. We found higher PD-L1 mRNA level but not DNA copy number in breast cancer than normal breast tissue, and higher PD-L1 expression in TNBC than other subtypes. Moreover, we found a positive relationship between PD-L1 expression in TNBC and metabolic complications in patients. Next, obesity/MetS related M1 macrophage was found to promote the expression of PD-L1 in breast cancer cells cocultured with polarized macrophages derived from either monocyte-like cell line THP-1 or Wistar rat models. IL6/JAK/STAT pathway was further identified to be involved in the process. In addition, we discovered that the PD-L1 expression promoted by obesity/MetS could be restored by telmisartan, one of the angiotensin II receptor blockers (ARBs) and could affect macrophage polarization, through its selective peroxisome proliferator-activated receptor-gamma (PPARG) activation and NFKB p65 inhibition and therefore downregulates IL6 secretion from M1 macrophage.

Abstract
The membrane-spanning domain (MSD) of the transmembrane subunit (TM) anchors the envelope glycoprotein (Env) on the lipid bilayer of the host cell membrane and virions. Its functions include membrane fusion efficiency and intracellular trafficking of the lentivirus envelope protein. Our study aimed to determine the MSD of bovine immunodeficiency virus (BIV) glycoprotein 45 (gp45) and reveal structural characteristics of the BIV Env protein. We have predicted the region of the BIV MSD and obtained the sequence using bioinformatics software. Various kinds of assays, including analogy analysis, fluorescence microscopy, and dye-transfer-based assays, were carried out to validate the prediction. The results, for the first time, show that the BIV MSD is located at the D170 to M191 amino acids of gp45, and the identified MSD divides gp45 into the extracellular domain (ED), MSD and cytoplasmic domain (CT). We further found that the BIV MSD had a similar structure and function as the HIV MSD using amino acid sequence alignment and fluorescence microscopy. Additionally, the dye-transfer-based assay demonstrates that deletion of the BIV MSD efficiently decreases cell-cell fusion. Based on the identification of the MSD, a "snorkeling" model, in which the flanking charged amino acid residues are buried in the lipid bilayer while their side chains interact with polar head groups, was proposed for the BIV MSD. Ultimately, we further improved the primary structure of the BIV envelope glycoprotein.

Abstract
BACKGROUND The Decipher genomic classifier (GC) is increasingly being used to determine metastasis risk in men with localized prostate cancer (PCa). Whether GCs predict for the presence of occult metastatic disease at presentation or subsequent metastatic progression is unknown. OBJECTIVE To determine if GC scores predict extraprostatic 68Ga prostate-specific membrane antigen (68Ga-PSMA-11) positron emission tomography (PET) positivity at presentation. DESIGN, SETTING, AND PARTICIPANTS Between December 2015 and September 2018, 91 PCa patients with both GC scores and pretreatment 68Ga-PSMA-11 PET scans were identified. Risk stratification was performed using the National Comprehensive Cancer Network (NCCN), Cancer of the Prostate Risk Assessment (CAPRA), and GC scores. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Logistic regression was used to identify factors correlated with PSMA-positive disease. RESULTS AND LIMITATIONS The NCCN criteria identified 23 (25.3%) and 68 patients (74.7%) as intermediate and high risk, while CAPRA scores revealed 28 (30.8%) and 63 (69.2%) as low/intermediate and high risk, respectively. By contrast, only 45 patients (49.4%) had high-risk GC scores. PSMA-avid pelvic nodal involvement was identified in 27 patients (29.7%). Higher GC score was significantly associated with pelvic nodal involvement (odds ratio [OR] 1.38 per 0.1 units; p=0.009) and any PSMA-avid nodal involvement (pelvic or distant; OR 1.40 per 0.1 units; p=0.007). However, higher GC score was not significantly associated with PSMA-avid osseous metastases (OR 1.11 per 0.1 units; p=0.50). Limitations include selection bias for patients able to receive both tests and the sample size. CONCLUSIONS Each 0.1-unit increase in GC score was associated with an approximate 40% increase in the odds of PSMA-avid lymph node involvement. These data suggest that patients with GC high risk might benefit from more nodal imaging and treatment intensification, potentially via pelvic nodal dissection, pelvic nodal irradiation, and/or the addition of chemohormonal agents. PATIENT SUMMARY Patients with higher genomic classifier scores were found to have more metastatic lymph node involvement on prostate-specific membrane antigen imaging.

Abstract
OBJECTIVE In addition to the traditional TNM N staging system, lymph node ratio (LNR) and log odds of metastatic lymph nodes (LODDS) staging methods were developed in cancers. This study aimed to examine their relative prognostic performance in patients with adenocarcinoma of the esophagogastric junction (AEG). PATIENTS AND METHODS Patients who underwent surgical resection for AEG were identified from the Surveillance, Epidemiology, and End Results (SEER) Program and the First Affiliated Hospital of Xi'an Jiaotong University as the training and validation sets, respectively. The Akaike's Information Criterion (AIC), Harrell's C statistic, and ROC curves were utilized for comparison. RESULTS A total of 735 patients were involved in the training set. LODDS and LNR staging systems had better prognostic performance than the TNM N staging systems (when considered as a categorical variable: C index = 0.728 and 0.712 vs 0.671; AIC: 6247.537 and 6265.996 vs 6320.045; AUC: 0.762 and 0.719 vs 0.692. For the continuous model: C index = 0.675 and 0.686 vs 0.658; AIC = 6243.740 and 6261.027 vs 6355.077; AUC = 0.778 and 0.733 vs 0.693). In the validation set of 183 patients, the TNM N staging scheme outperformed the LODDS and LNR staging systems (C index = 0.788 vs 0.779 and 0.767; AIC = 1014.702 vs 1026.899 and 1025.288; AUC = 0.806 vs 0.787 and 0.791) when considered a categorical variable. However, when considered a continuous variable, the LODDS and LNR staging systems were better than the TNM N staging system (C index = 0.724 and 0.733 vs 0.747; AIC = 1018.075 and 1025.803 vs 1026.085; AUC = 0.811 and 0.810 vs 0.806). CONCLUSIONS The LNR and LODDS staging schemes could be considered new options for prognostic prediction of AEG with respect to lymph node status, especially when considered as continuous variables.

Abstract
BACKGROUND There has been little research on perioperative hypercoagulability in non-small-cell lung cancer patients. The D-dimer can be used to evaluate the hypercoagulability in cancer patients. METHODS Eighty-five non-small-cell lung cancer patients were included in the study. The plasma D-dimer levels during the preoperative and 3rd and 9th day postoperative period were prospectively examined and analyzed along with the clinicopathological characteristics. RESULTS The medians (interquartile range) of the preoperative, 3rd and 9th day postoperative D-dimer levels were 1.09 (0.77) mg/L, 3.35 (2.31) mg/L and 4.1 (2.55) mg/L respectively (P= 0.00). The preoperative D-dimer level was related with the stage (P= 0.004). The preoperative and the 3rd day postoperative D-dimer levels were both related to patient age (P= 0.014, P= 0.034). The 3rd day postoperative D-dimer levels were arbitrarily stratified into three groups, adenocarcinoma dominated the high and low groups while squamous cell carcinoma dominated the median one (exact P= 0.02). The pneumonectomy group did not show a higher 3rd day postoperative D-dimer level than the lobectomy group (P= 0.064). CONCLUSION Non-small-cell lung cancer patients had increasing hypercoagulability within the first 9 postoperative days. Preoperative hypercoagulability was close related with tumor stage. Heterogeneity existed among postoperative hypercoagulability.

Abstract
A temperature-insensitive sum frequency generation method based on thermally induced phase mismatch compensation is proposed to enhance the thermal stability and scale up the output power of ultraviolet (UV) lasers. In the method, three LiB3O5 crystals are cascaded for sum frequency generation of a 355-nm UV laser, and the two crystals at the ends are employed for frequency conversion; the middle one, which is not required to be phase matched and has an opposite sign of first temperature derivative of phase mismatch, compensates the thermally induced phase mismatch generated in the first crystal. The temperature acceptance bandwidth of frequency conversion in the three cascaded crystals is about double that in a single long crystal with the same interaction length.

Abstract
p38 mitogen-activated protein kinase (MAPK) signaling has been implicated in the cancer development and progression. However, the precise mechanism of this association remains unknown. The aim of the present study was to evaluate the association between p38 and cancer progression, including investigations into the effects on cell proliferation, resistance to thalidomide, indoleamine 2,3-dioxygenase (IDO) expression and prognosis in patients with esophageal cancer. The present retrospective study included patients with stage I–III esophageal cancer. A total of 228 patients with esophageal cancer were recruited to analyze the expression of phosphorylated (p)-p38 and IDO in tumor, and normal tissues through immunohistochemistry. Depression status was measured using the Zung Self-Rating Depression Scale. P38 cDNA was transfected into esophageal cancer cells to assess tumor cell viability, sensitivity to thalidomide treatment and IDO gene expression. Western blotting and flow cytometry was used to analyze protein expression alterations, and apoptosis in esophageal cancer cells. P-p38 protein was expressed in 68.9% of cancer tissues, and was significantly associated with depressive symptoms, tumor recurrence and poor survival of patients. In vitro experiments revealed that the expression of p-p38 induced esophageal cancer Eca-109 and TE-1 cell viability, and resistance to thalidomide treatment, as well as in the expression of IDO without the application of lipopolysaccharides. Further follow-up of patients revealed that depression was also an independent factor for early recurrence and overall survival rate. Altered p38 MAPK expression was associated with poor outcome in patients with esophageal cancer. p38 may be a potential biomarker for the prediction of depressive symptoms and prognosis in patients with esophageal cancer.

Abstract
Multi-drug resistance (MDR), immune suppression and decreased apoptosis are important causes of therapy-failure in leukaemia. Short interfering RNAs (siRNAs) down-regulate gene transcription, have sequence-independent immune-stimulatory effects and synergize with other anti-cancer therapies in some experimental models. We designed a siRNA targeting MDR1 with 5'-triphosphate ends (3p-siRNA-MDR1). Treatment of leukaemia cells with 3p-siRNA-MDR1 down-regulated MDR1 expression, reduced-drug resistance and induced immune and pro-apoptotic effects in drug-resistant HL-60/Adr and K562/Adr human leukaemia cell lines. We show mechanisms-of-action of these effects involve alterations in the anti-viral cytosolic retinoic acid-inducible protein-I (RIG-I; encoded by RIG-I or DDX58) mediated type-I interferon signal induction, interferon-gamma-inducible protein 10 (IP-10; encoded by IP10 or CXCL10) secretion, major histocompatibility complex-I expression (MHC-I) and caspase-mediated cell apoptosis. 3p-siRNA-MDR1 transfection also enhanced the anti-leukaemia efficacy of doxorubicin. These data suggest a possible synergistic role for 3p-siRNA-MDR1 in anti-leukaemia therapy.

Abstract
BACKGROUND Fibrinogen (FIB) is an important source of fibrin, which plays a crucial role in circulating tumor cells (CTCs) extravasation and distant metastasis development. We hypothesize it's stable final product, plasma D-dimer, may be associated with CTCs appearance and can reflect the metastatic phenotype in cancer patients. METHODS We first verified our hypothesis in different murine gastric cancer metastasis models in vivo, plasma D-dimer and fibrinogen as well as its degradation products were directly examined in three metastasis immune-deficient mouse models and in controls. Next, we gathered and analyzed the result of plasma D-dimer levels and CTCs numbers in 41 advanced primary gastric cancer (GC) patients. A follow-up study was conducted in these patients. RESULTS In three in vivo murine metastasis models, plasma D-dimer levels were extremely elevated in a hematogenous and intraperitoneal murine model of metastasis compared with a subcutaneous tumor model and the control group, supporting our previous hypothesis. While in 41 GC patients, the result displayed that plasma D-dimer levels were remarkably increased in patients with distant metastases, especially in visceral metastases patients. Additionally, linear association was shown between D-dimer level and CTCs numbers (R 2 = 0.688, p < 0.001), additionally, plasma D-dimer represent a better survival predictor than CTCs. CONCLUSIONS Plasma D-dimer is an essential accompaniment of CTCs in GC that is easy to measure and lower in cost, and can be used in the detection of hematogenous metastasis.

Abstract
Malignant tumours of the appendix are quite rare, especially appendiceal adenocarcinomas, which may be difficult to detect preoperatively or intraoperatively. We collected data for 1404 patients with adenocarcinoma of the appendix from the Surveillance, Epidemiology, and End Results Program (SEER) database to explore the potential associations between clinicopathological factors and overall survival. Furthermore, a novel nomogram for predicting prognosis was developed based on our analysis of the SEER data. The nomogram prediction model included seven prognostic factors derived based on different clinical estimates. When compared with the traditional tumour-node-metastasis (TNM) staging system, the nomogram prediction model showed superior discriminatory power (Harrell’s C-index, 0.741 vs. 0.686) and a greater degree of similarity to actual 5-year overall survival after calibration (Akaike Information Criterion index, 5270.781 vs. 5430.141). Finally, we provide recommendations for the management of patients with adenocarcinoma of the appendix. Notably, we found the depth of adenocarcinoma invasion may be used as an indicator to determine the optimal surgical approach. For mucinous adenocarcinomas of the appendix, because these tumours are characterized by unique biological behaviour, intraoperative hyperthermic intraperitoneal chemotherapy (HIPEC) is recommended. However, whether systematic chemotherapy should be administered to patients with adenocarcinoma of the appendix requires further investigation.

Abstract
We conducted a meta-analysis to explore the relationships between p14ARF gene methylation and clinicopathological features of colorectal cancer (CRC). Databases, including Pubmed, Embase and Cochrane Library, were searched and, finally, a total of 18 eligible researches encompassing 1988 CRC patients were selected. Combined odds ratios (ORs) with 95% confidence intervals (95% CIs) were evaluated under a fixed effects model for absence of heterogeneity. Significant associations were observed between p14ARF gene methylation and tumor location (OR = 2.35, 95% CI: 1.55–3.55, P = 0.001), microsatellite instability (MSI) status (OR = 3.28, 95% CI: 2.12–5.07, P<0.0001). However, there were no significant associations between p14ARF gene methylation and tumor stage, tumor differentiation. We concluded that p14ARF gene methylation may be significantly associated with tumor location, and MSI status of CRC.

Abstract
Background Plasma D-dimer levels have been shown to be high in advanced tumor stage patients and can be used to predict clinical outcome in cancer patients. As most advanced tumor stage patients exhibit asymptomatic metastasis, which contributes to early tumor recurrence after surgery, we hypothesized that plasma D-dimer levels can be used to predict patients with potential metastasis. Methods We enrolled 1042 primary gastric cancer patients in three multiple cancer centers in Northwest China and examined plasma D-dimer levels using the latex-enhanced immunoturbidimetric assay (LEIA) method. Plasma D-dimer levels were compared with the clinicopathological characteristics in this large-scale case-control study with follow up. We also performed regular follow-up studies for 395 patients to analyze the 2-year survival rate and early tumor recurrence. Results In this large-scale clinical study, we found that plasma D-dimer levels were increased in patients with distant metastasis and especially hematogenous metastasis patients. The cut-off value of the D-dimer levels was determined to be 1.5 mg/ml based on the ROC curve, and the sensitivity and specificity for metastasis prediction were 61.9% and 86.6%, respectively. Additionally, patients with high D-dimer levels displayed early tumor recurrence and poor outcome during the follow-up study. Conclusion Plasma D-dimer may represent an easy to measure and lower cost marker for the testing of gastric cancer patients to predict asymptomatic hematogenous metastasis.

Abstract
The aim of this study was to evaluate hypermethylation of the spastic paraplegia-20 promoter as a potential biomarker and prognostic factor in gastric cancer. Four human gastric cancer cell lines, 41 primary gastric cancer tissue samples and corresponding peripheral blood samples, and blood samples of 21 healthy individuals were analyzed using methylation-specific polymerase chain reaction. Additionally, the expression of Spartin, the protein product encoded by spastic paraplegia-20, was analyzed in tissues from 119 gastric cancer patients who underwent radical gastrectomy at Xi'an Jiaotong University between 2005 and 2010. Hypermethylation of the spastic paraplegia-20 promoter was observed in 26 of 41 (63.4 %) primary tumors and 1 of 35 (2.9 %) adjacent normal gastric tissues (P < 0.001). Among matched peripheral blood samples from gastric cancer patients, 48.8 % exhibited hypermethylation of the spastic paraplegia-20 promoter. In contrast, no methylation of the spastic paraplegia-20 promoter was observed in blood samples from 21 healthy individuals (P < 0.001). Additionally, demethylation by 5-aza-dC treatment led to gene reactivation in gastric cancer cells exhibiting hypermethylation of the spastic paraplegia-20 promoter. Finally, immunohistochemical staining indicated that low expression of Spartin was a prognostic factor predicting poor outcomes in gastric cancer patients (P = 0.037). These findings suggested that hypermethylation of the spastic paraplegia-20 promoter occurred frequently in gastric cancer and could represent a novel prognostic factor. Furthermore, detection of this molecular feature in the peripheral blood of gastric cancer patients suggested that evaluation of the methylation state of the spastic paraplegia-20 promoter may be used as a noninvasive screening method.

Abstract
Abnormal glucose metabolism from hyperglycemia or diabetes aggravates the progression of pancreatic cancer. It is unknown whether high glucose has an impact on the antitumor effect of 5-fluorouracil (5-Fu) and whether targeting aberrant glucose metabolism using 2-deoxy-D-glucose (2-DG) may reverse this effect in high-glucose microenvironments. The cell viability of AsPC-1 and Panc-1 was analyzed by MTT assay following 5-Fu treatment at different glucose concentrations. Altered sensitivity to 5-Fu by 2-DG was also analyzed. LY294002 was used to inhibit PI3K-Akt signaling to determine the mechanism involved. In response to glucose, 5-Fu-induced cell growth inhibition was attenuated in a dose-dependent manner, accompanied with activated p-Akt, while 2-DG enhanced 5-Fu-induced cell growth inhibition. Moreover, blocking the PI3K/Akt pathway by LY294002 effectively eliminated 2-DG-induced apoptosis. In conclusion, high glucose weakens the antitumor effect of 5-Fu via PI3K/Akt signaling. Using 2-DG in combination with 5-Fu significantly increased their therapeutic effectiveness in high-glucose microenvironments.

Abstract
BACKGROUND The incidence of the esophagogastric junction cancer is growing rapidly. The purpose of this study is to clarify the outcome of the ratio between metastatic and examined lymph nodes in esophagogastric junction cancer patients with or without 7 examined lymph nodes. METHODS A total of 3,481 patients who underwent operation are identified from the Surveillance, Epidemiology, and End Results database. Different lymph nodes resected groups are analyzed to test the lymph nodes ratio factor. RESULTS There are 2522 patients with 7 or more lymph nodes resected and 959 patients with less than 7 lymph nodes resected. Lymph nodes ratio and lymph node involvement are independent prognostic factors. But the lymph nodes ratio categories have a better prognostic value than the lymph node involvement categories. Compared with lymph node involvement categories, lymph nodes ratio categories represent patients with more homogeneous overall survival rate. CONCLUSIONS This study defines that the lymph nodes ratio is an independent prognostic factor for esophagogastric junction cancer. The lymph nodes ratio can prevent stage migration and may be a helpful system to predict the prognosis of esophagogastric junction cancer patients.

Abstract
BACKGROUND There has been little research on the perioperative D-dimer levels in oesophageal cancer patients. Plasma D-dimer levels can be used to predict the outcome in cancer patients. METHODS A cancer group of 66 oesophageal cancer patients and a control group of 12 patients with benign disease were enrolled in this cohort study. The plasma D-dimer levels during the pre-operation and 3rd and 9th day post-operation periods were prospectively examined and analysed between the two groups. Plasma D-dimer levels were also compared with the clinicopathological characteristics and 3-year survival of the oesophageal cancer patients. RESULTS Plasma D-dimer levels increased in both groups after surgery, but they were significantly higher in the cancer group. In oesophageal cancer patients, pre-operation plasma D-dimer levels were significantly higher in TNM stage IV patients. Perioperative plasma D-dimer levels significantly increased after surgery, and the survival was shortened in those patients whose D-dimer levels on the 3rd and 9th post-operative day above the median. In addition, increased plasma D-dimer levels at the 3rd and 9th days after surgery were influenced by the patient's age. CONCLUSION In oesophageal cancer patients, D-dimer levels increased after surgery, and the increases were associated with poor outcomes.

Abstract
Gastric cancer (GC) is one of the most common malignant tumors with a high rate of recurrence, which results in surgery being unsuccessful. Therefore, it is important to find the reason for the surgery failing. The purpose of the present study was to investigate a factor related to recurrence. Expression of KIAA0101 was assessed in 61 paired human primary GC and non-cancerous gastric tissue using immunohistochemistry. After surgery, all 61 patients were followed regularly for more than 24 months or until death to analyze the 2-year survival rate and recurrence. After suppressing KIAA0101 by RNA interference in human GC cell lines, the cell viability was detected using MTT. We are first to find that KIAA0101 was elevated in GC tissues compared with paired non-cancerous gastric tissues. Immunohistochemical staining also revealed the predominant nuclear localization of KIAA0101 protein. Despite these findings, GC patients with elevated KIAA0101 expression levels exhibited a high recurrence and subsequently poor prognosis in the survival study. Also, cell viability was significantly inhibited after suppressing KIAA0101 in GC cells, suggesting that KIAA0101 might promote cancer cell proliferation. KIAA0101 is increased in human GC and is a marker of recurrence.

Abstract
Inflammation can act as a crucial mediator of epithelial-to-mesenchymal transition (EMT). In this study, we show that oncostatin M (OSM) is expressed in an autocrine/paracrine fashion in invasive breast carcinoma. OSM stimulation promotes spontaneous lung metastasis of MCF-7 xenografts in nude mice. A conspicuous epigenetic transition was induced by OSM stimulation not only in breast cancer cell lines but also in MCF-7 xenografts in nude mice. The expression of miR-200 and let-7 family members in response to OSM stimulation was downregulated in a signal transducer and activator of transcription factor 3 (Stat3)-dependent manner, resulting in comprehensive alterations of the transcription factors and oncoproteins targeted by these microRNAs. Inhibition of Stat3 activation or the ectopic expression of let-7 and miR-200 effectively reversed the mesenchymal phenotype of breast cancer cells. Stat3 promotes the transcription of Lin-28 by directly binding to the Lin-28 promoter, resulting in the repression of let-7 expression and concomitant upregulation of the let-7 target, high-mobility group A protein 2 (HMGA2). Knock down of HMGA2 significantly impairs OSM-driven EMT. Our data indicate that downregulation of let-7 and miR-200 levels initiates and maintains OSM-induced EMT phenotypes, and HMGA2 acts as a master switch of OSM-induced EMT. These findings highlight the importance of Stat3-coordinated Lin-28B-let-7-HMGA2 and miR-200-ZEB1 circuits in the cytokine-mediated phenotypic reprogramming of breast cancer cells.

Abstract
Micro-RNAs (miRNAs) have been found to be implicated in a very wide range of physiological processes. This study was aimed to investigate the regulation of miRNA-429 (miR-429) in gastric cancer cells on cell proliferation and apoptosis. Quantitative PCR was employed to detect the expressions of miR-429 after eukaryotic expression plasmid of miR-429 and its inhibitor were transiently transfected into poorly differentiated human gastric cancer cell line BGC823. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction assays were used to examine proliferation ability. Apoptosis was analyzed by flow cytometry after transfection. The results showed that 48 h after transfection, overexpression of miR-429 reached maximum efficiency. Compared with mock transfection, miR-429 inhibited tumor cell proliferation significantly (P < 0.05) at 48 h and 72 h. of Overexpression of miR-429 promoted tumor cell apoptosis when compared with mock transfected cells (P < 0.05). On the contrary, miR-429 inhibitor promoted tumor cell proliferation and inhibited apoptosis when compared with controls (P < 0.05). Our results suggested that miRNA-429 may serve as a tumor suppressor during tumorigenesis of gastric cancer and may be a potential gastric cancer therapeutic target.

Abstract
BACKGROUND AND OBJECTIVE Some operable non-small cell lung cancer (NSCLC) patients have poor prognosis shortly after the surgery. D-dimer (DD) is an independent prognosis factor of lung cancer, especially for inoperable patients. The aim of the study is to investigate whether the pre-operative plasma DD level could predict the poor prognosis shortly after the surgery in operable NSCLC patients. METHODS The pre-operative plasma DD level of 56 newly diagnosed NSCLC patients without metastasis was examined. All the patients had been followed for one year post-operatively and the end-point was the occurrence of the poor prognosis incident including any sign of the metastasis, local recurrence or death related with the lung cancer. Difference of prognosis according to pre-operative plasma DD level was compared by Chi-square test. Diseases progress was analyzed by Kaplan-Meier method. RESULTS Among 56 NSCLC patients, 91% had received the curative resections (44 lobectomy and 7 pneumonectomy). There were still 2 cases of the wedge resection and 3 cases of the exploration. The median of the pre-operative plasma DD level was 1.05 (0.55) mg/L. The patients were allocated into two subgroups by the median of the DD levels. There were 11 patients with poor prognosis within one year after the resection in the high DD subgroup, while 3 patients in the low DD subgroup (P=0.03, OR=4.89, 95%CI: 1.2-20.1). The diseases progress curves were significantly different between the high and low subgroups (P=0.024). Based on plasma DD level, the poor prognosis incident within one year after the surgery was best predicted in the early stage (I, II) of the NSCLC, especially in adenocarcinoma patients. CONCLUSION The pre-operative plasma DD levels may predict the poor prognosis within one year after the surgery in NSCLC. The measurement of the fibrinolysis marker may help to exclude the unfit patients for the surgery.
