Abstract
Chinese guidelines recommend POF (paclitaxel, oxaliplatin, and 5-FU/levoleucovorin) as first-line treatment for advanced gastric cancer (AGC). Apatinib can augment the antitumor effect of paclitaxel, oxaliplatin, or fluorouracil in preclinical studies of AGC. A phase I clinical trial was conducted to evaluate the anticancer activity and maximum tolerated dose (MTD) of apatinib plus POF in treatment-naïve patients with AGC and to establish a recommended phase II dose. Participants received escalating doses of daily oral apatinib (250, 375, 500, 625, 750, and 850 mg) plus POF every 2 weeks using a conventional "3 + 3" study design. Among 21 treated patients, one experienced a dose-limiting toxicity (grade 3 skin ulceration at 850 mg). No MTD was reached. Apatinib 750 mg plus POF was recommended for phase II study. The most common grade 3-4 adverse events (AEs) were neutropenia (33.3%), mucositis (14.3%), and hand-foot syndrome (14.3%). Median progression-free and overall survival were 10.4 months (95% CI: 6.3, 14.6) and 18.4 months (95% CI: 9.8, 28.2), respectively. Apatinib up to 850 mg coadministered with POF was well tolerated with manageable AEs. The safety and anticancer activity of this regimen warrants its further investigation as first-line treatment for AGC in a larger study.

Abstract
Despite the known benefits of data-driven approaches, the lack of approaches for identifying functional neuroimaging patterns that capture both individual variations and inter-subject correspondence limits the clinical utility of rsfMRI and its application to single-subject analyses. Here, using rsfMRI data from over 100k individuals across private and public datasets, we identify replicable multi-spatial-scale canonical intrinsic connectivity network (ICN) templates via the use of multi-model-order independent component analysis (ICA). We also study the feasibility of estimating subject-specific ICNs via spatially constrained ICA. The results show that the subject-level ICN estimations vary as a function of the ICN itself, the data length, and the spatial resolution. In general, large-scale ICNs require less data to achieve specific levels of (within- and between-subject) spatial similarity with their templates. Importantly, increasing data length can reduce an ICN's subject-level specificity, suggesting longer scans may not always be desirable. We also find a positive linear relationship between data length and spatial smoothness (possibly due to averaging over intrinsic dynamics), suggesting studies examining optimized data length should consider spatial smoothness. Finally, consistency in spatial similarity between ICNs estimated using the full data and subsets across different data lengths suggests lower within-subject spatial similarity in shorter data is not wholly defined by lower reliability in ICN estimates, but may be an indication of meaningful brain dynamics which average out as data length increases.

Abstract
Colorectal cancer is one of the most common malignancies worldwide. Liver metastasis is the major direct cause of colorectal cancer-related deaths. Although radical resection is the most effective treatment for colorectal cancer liver metastasis, several patients are not eligible for surgery. Therefore, there is a need to develop novel treatments based on the understanding of the biological mechanisms underlying liver metastasis in colorectal cancer. This study demonstrated that activin A/ACVR2A inhibits colon cancer cell migration and invasion, as well as suppresses the epithelial-to-mesenchymal transition of mouse colon cancer cells. This finding has been further validated in animal experiments. Mechanistic studies revealed that activin A binds to Smad2 (instead of Smad3) and activates its transcription. Analysis of the paired clinical samples further confirmed that the expression levels of ACVR2A and SMAD2 were the highest in adjacent healthy tissues, followed by primary colon cancer tissues and liver metastasis tissues, suggesting that ACVR2A downregulation may promote colon cancer metastasis. Bioinformatics analysis and clinical studies demonstrated that ACVR2A downregulation was significantly associated with liver metastasis and poor disease-free and progression-free survival of patients with colon cancer. These results suggest that the activin A/ACVR2A axis promotes colon cancer metastasis by selectively activating SMAD2. Thus, targeting ACVR2A is a potential novel therapeutic strategy to prevent colon cancer metastasis.

Abstract
OBJECTIVE The aim of the study was to summarize the findings of the studies documenting the efficacy and safety of perampanel when used in children/adolescents or adults, either as add-on therapy or as monotherapy. MATERIALS AND METHODS A systematic search was conducted using PubMed, EMBASE and Scopus. Only studies with a cohort-based approach (either prospective or retrospective) were included. We were interested in real-world studies and therefore, studies with a highly regulated environment, such as randomized controlled trials, were excluded. The primary outcomes of interest were retention rates, response rates and seizure-free rates. Random effects model was used for the analysis. Effect sizes were reported as pooled prevalence along with 95% confidence intervals. RESULTS A total of 34 studies were included. The retention rates, within 24 months from initiation of treatment as an add-on therapy, ranged between 65% to 77% among children and adolescents. For adults, the retention rate varied between 56 to 77% within 24 months from initiation of treatment. The response rate was around 70% in children/adolescents and 52% in adults at 24 months of follow-up. Around 25% of children and adolescents and 37% of adults were seizure-free at 24 months follow-up period. The proportion of children/adolescents and adults reporting any treatment-related adverse effects was 29% and 41%, respectively. The commonly reported adverse effects were dizziness/drowsiness, somnolence, behavioral problems (irritability, aggression, anxiety, mood changes), postural instability/gait problems, fatigue and weight gain. CONCLUSIONS Perampanel might be an effective anti-epileptic drug in both children/adolescents and adults when used as an adjunct therapy. More data is required to comment on its use as monotherapy. Careful monitoring for psychiatric problems and behavioral disturbances is required, both prior to initiating treatment as well as during the course of management. Studies with long-term follow-up may are needed to confirm the findings of this meta-analysis.

Abstract
236 Background: The upregulated expression of CXCL1 has been validated in colorectal cancer patients. As a potential biotherapeutic target for colorectal cancer, the mechanism by which CXCL1 affects the development of colorectal cancer is not clear. Methods: Expression data of CXCL1 in colorectal cancer were obtained from the GEO database and verified using the GEPIA database and the TIMER 2.0 database. Knockout and overexpression of CXCL1 in colorectal cancer cells by CRISPR/Cas and "Sleeping Beauty" transposon-mediated gene editing techniques. Cell biological function was demonstrated by CCK-8, transwell chamber and Colony formation assay. RT-qPCR and Western Blot assays measured RNA and protein expression. Protein localization and expression were measured by immunohistochemistry and immunofluorescence. Results: Bioinformatics analysis showed significant overexpression of CXCL1 in the colorectal cancer tissues compared to normal human tissues, and identified CXCL1 as a potential therapeutic target for colorectal cancer. We demonstrate that CXCL1 promotes the proliferation and migration of colon cancer cells and has a facilitative effect on tumor angiogenesis. Furthermore, CXCL1 elevation promoted the migration of M2-tumor associated macrophages (TAMs) while disrupting the aggregation of CD4+ and CD8+ T cells at tumor sites. Mechanistic studies suggested that CXCL1 activates the NF-κB pathway. In the in vivo colon cancer transplantation tumor model, treatment with the P300 inhibitor C646 significantly inhibited the growth of CXCL1-overexpressing colon cancer. Conclusions: CXCL1 promotes colon cancer development through activation of NF-κB/P300, and that CXCL1-based therapy is a potential novel strategy to prevent colon cancer development.

Abstract
Liquid biopsy, which generally refers to the analysis of biological components such as circulating nuclear acids and circulating tumor cells in body fluids, particularly in peripheral blood, has shown good capacity to overcome several limitations faced by conventional tissue biopsies. Emerging evidence in recent decades has confirmed the promising role of liquid biopsy in the clinical management of various cancers, including colorectal cancer, which is one of the most prevalent cancers and the second leading cause of cancer-related deaths worldwide. Despite the challenges and poor clinical outcomes, patients with metastatic colorectal cancer can expect potential clinical benefits with liquid biopsy. Therefore, in this review, we focus on the clinical prospects of liquid biopsy in metastatic colorectal cancer, specifically with regard to the recently discovered various biomarkers identified on liquid biopsy. These biomarkers have been shown to be potentially useful in multiple aspects of metastatic colorectal cancer, such as auxiliary diagnosis of metastasis, prognosis prediction, and monitoring of therapy response.

Abstract
Soil contamination by arsenic (As) is an important environmental issue globally. Intercropping of hyperaccumulators with main crop is typically applied for remediation of As-contaminated soil. Most hyperaccumulators are wild plants with small biomass and slow growth rates. Thus, remediation is slow. Here, we propose an effective intercropping system for remediation of As-contaminated paddy soil. Four treatments-intercropping with water spinach (Ipomoea aquatica Forsk) (T1), water celery (Oenanthe javanica (Blume) DC.) (T2), or Guangdong white arrowhead (Sagittaria sagittifolia L. var) (T3), with rice (Oryza sativa L.) monoculture (control, CK)-were used. Compared with the CK, grain yield per plant of rice under T1 and T2 increased by 58.13% and 10.48%, respectively, but decreased by 46.90% in T3. As concentration, bioaccumulation factor, and translocation factor in brown rice were significantly lower in the intercropping treatments than in CK. As removal by water spinach was 7.04 and 1.47 times that by water celery and arrowhead, respectively. The pH of paddy soil was significantly higher in all treatments than in CK, and iron plaque on rice roots under T1 and T2 decreased significantly but increased significantly under T3 compared with that of CK. Rice intercropped with water spinach had the best remediation effect. Novelty Statement: We believe that the following highlights of this manuscript will make it interesting to general readers of this journal.First, in recent years, many articles about intercropping system for the remediation of soil heavy metal pollution focus on dry land, and few studies have focused on paddy soil. The present study was on arsenic-contaminated paddy soil remediation.Second, water spinach, water celery, and arrowhead have great potential for phytoremediation. Studies have shown that these three aquatic vegetables play a role in the removal of certain pollutants, such as heavy metals. Moreover, when intercropped with rice, they can effectively increase rice yield and reduce rice diseases and insect pests. However, studies on remediation of arsenic-contaminated soil by intercropping aquatic vegetables and rice have not been reported. We propose here a rice-aquatic vegetables (water spinach, water celery and arrowhead) intercropping pattern for remediation of arsenic in soil.Third, according to the arsenic concentration and removal rate, we used a bioaccumulation factor, translocation factor, and arsenic removal per unit area of plants for the quantitative evaluation of the remediation effects of the intercropping systems. We found that the intercropping of rice and water spinach could be used to remediate arsenic-contaminated soil. Moreover, the extraction contents of arsenic using intercropping with water spinach was higher than that achieved in a previous study that applied intercropping with the arsenic hyperaccumulator Pteris vittata over the same growth time. This study provides a reference for realizing both remediation and increased production in arsenic-contaminated soil and for promoting sustainable development of agriculture.

Abstract
Objective: To investigate the spectrum and antimicrobial resistance of major pathogens causing nosocomial infections in China, 2018. Methods: Non-duplicated nosocomial cases as well as pathogens causing bloodstream infections (BSI), hospital-acquired pneumonia (HAP) and intra-abdominal infections (IAI) from 11 teaching hospitals across China were collected. The minimum inhibitory concentrations (MICs) of clinically significant strains were determined by agar dilution method or broth microdilution method. The Clinical and Laboratory Standards Institute (CLSI) M100-S29 criteria were used for interpretation, and the WHONET-5.6 software was used in data analysis. Results: A total of 1 590 cases were collected, including 831 cases from BSI, 450 cases from HAP and 309 cases from IAI. The most prevalent pathogens causing BSI were Escherichia coli (29.2%, 243/831), Klebsiella pneumoniae (16.2%, 135/831) and Staphylococcus aureus (10.1%, 84/831); the most prevalent pathogens causing IAI were E. coli (26.2%, 81/309), Enterococcus faecium (15.5%, 48/309) and K. pneumoniae (13.3%, 41/309); while Acinetobacter baumanii (24.7%, 111/450), Pseudomonas aeruginosa (20.7%, 93/450) and K. pneumoniae (16.2%, 73/450) were dominated in HAP. All S. aureus were susceptible to tigecycline, linezolid, daptomycin and glycopeptides; 77.8% (105/135) of S. aureus strains were susceptible to ceftaroline. Methicillin-resistant S. aureus (MRSA) accounted for 29.6% (40/135) of all the S. aureus, and was lower than the accounted rate of methicillin-resistant coagulase-negative Staphylococcus (MRCNS) (83.7%, 41/49). One E. faecium strain (1.1%, 1/95) resistant to vacomycin and teicoplanin and one E. faecalis strain (2.3%, 1/43) resistant to linezolid was found. The prevalence of extended-spectrum β-lactamase (ESBL) was 56.1% (193/344) in E. coli and 22.1% (55/249) in K. pneumonia; the rate of carbapenem resistant E. coli and K. pneumonia was 4.1% (14/344) and 22.9% (57/249), respectively; the percentage of ceftazidime/avibactam resistant E. coli and K. pneumonia was 2.3% (8/344) and 2.0% (5/249), respectively; the percentage of colistin resistant E. coli and K. pneumonia was 1.5% (5/344) and 7.6% (19/249), respectively; no E. coli and K. pneumonia strains were found resistant to tigecycline. The rate of carbapenem resistant A. baumanii and P. aeruginosa were 78.9% (146/185) and 36.7% (66/180), respectively. A. baumanii showed low susceptibility to the antimicrobial agents except colistin (99.5%, 184/185) and tigecycline (91.4%, 169/185). Colistin, amikacin and ceftazidime/avibactam demonstrated high antibacterial activity against P. aeruginosa with susceptility rate of 100% (180/180), 93.3% (168/180) and 85.6% (154/180), respectively. Conclusions: Nosocomial Gram-negative pathogens show high susceptibilities to tigecycline, colistin and ceftazidime/avibactam in vitro. Antimicrobial resistance in A. baumannii is a serious problem. The prevalence of carbapenem-resistant Enterobacteriaceae has increased, which should be monitored continuously in China.

Abstract
OBJECTIVE This study aimed to explore the association of A kinase-interacting protein 1 (AKIP1) expression with clinicopathological characteristics and prognosis in gastric cancer patients. METHODS Data of 260 gastric cancer patients were retrospectively reviewed. AKIP1 expression in tumor tissue and non-cancerous tissue specimens was detected by immunohistochemistry and semi-quantitatively scored according to the staining intensity and density. Moreover, the clinicopathological features were retrieved, and disease-free survival (DFS) and overall survival (OS) were calculated. RESULTS A kinase-interacting protein 1 expression was increased in tumor tissues compared with non-cancerous tissues (P < .001). In terms of tumor features, tumor AKIP1 high expression correlated with elevated T stage (P < .001) and raised TNM stage (P = .042), while did not correlate with pathological grade (P > .999), tumor size (P = .060), N stage (P = .180), or tumor location (P > .999). Meanwhile, tumor AKIP1 was not associated with the non-tumor features either. Kaplan-Meier curves disclosed that AKIP1 high expression patients had shorter DFS (P = .004) and OS (P = .043) compared with AKIP1 low expression patients. Univariate Cox's regression showed that AKIP1 high expression correlated with shorter DFS (P = .005, hazard ratio [HR] = 1.635) and OS (P = .046, HR = 1.519), whereas multivariate Cox's regression displayed that AKIP1 did not independently predict worse DFS (P = .172, HR = 1.276) or shorter OS (P = .433, HR = 1.183). CONCLUSION A kinase-interacting protein 1 may serve as a potential biomarker for deteriorative tumor features and poor prognosis in gastric cancer patients.

Abstract
3591 Background: Metastatic cancers require further diagnosis to determine their primary tumor sites. However, the tissue-of-origin for around 5% tumors could not be identified by routine medical diagnosis according. With the development of machine learning techniques and the accumulation of big cancer data from TCGA and GEO, it is now feasible to predict cancer tissue-of-origin by computational tools. Methods: Developed a computational framework to infer tumor tissue-o. Results: Applied TOOme to the TCGA data containing 7,008 non-metastatic samples across 20 solid tumors including BLCA, BRCA, CESC, COAD, GBM and so on. 74 genes by gene expression profile and 6 genes by gene mutation are selected by the random forest process, which can be divided into two categories: (1) cancer type specific genes, which are highly expressed or mutated only in one specific cancer and (2) those expressed or mutated in several cancers with different levels of expression or mutation rates. Function analysis indicates that the selected genes are significantly enriched in gland development, urogenital system development, hormone metabolic process, thyroid hormone generation prostate hormone generation and so on. According to the multiple-label classification method, random forest performs the best with a 10-fold cross-validation prediction accuracy of 96%. We also use the 19 metastatic samples from TCGA and 256 cancer samples downloaded from GEO as independent testing data, for which TOOme achieves a prediction accuracy of 89%. The cross-validation validation accuracy is better than those using gene expression (i.e., 95%) and gene mutation (83%) alone. Conclusions: TOOme provides a quick yet accurate alternative to traditional medical methods in inferring cancer tissue-of-origin. In addition, the methods combining somatic mutation and gene expressions outperform those using gene expression or mutation alone.

Abstract
Background Liver cancer is a common malignant tumor with poor prognosis. The present study sought to identify potential signatures that can predict the prognosis of patients with liver cancer. Material/Methods The RNA sequencing (RNA-seq) and clinical information of liver cancer patients were obtained from the Cancer Genome Atlas (TCGA) database. Differentially expressed long noncoding RNAs (lncRNAs), microRNAs (miRNAs), and messenger RNAs (mRNAs) were identified between liver cancer and adjacent normal tissues. After predicting lncRNA–miRNA and miRNA–mRNA pairs using online databases, the competing endogenous RNA (ceRNA) networks were constructed. Furthermore, the prognostic value of these differentially expressed genes was evaluated using univariate and multivariate Cox regression analyses. Results After constructing the ceRNA network, 2 lncRNAs small nucleolar RNA host gene 1 (SNHG1) and chromosome 2 open reading frame 48 (C2orf48) with the most nodes were identified. Correlation analysis revealed that SNHG1 was correlated with miR-195 and C2orf48 was correlated with miR-195 and miR-93. High expression of SNHG1, C2orf48, and miR-93 can contribute to poorer clinical outcomes compared to low expression. Furthermore, low miR-195 expression was correlated with shorter survival time than was high expression. SNHG1 and C2orf48 were closely associated with histology grade. Univariate and multivariate Cox regression analyses confirmed that SNHG1 and C2orf48 are risk factors for liver cancer. Conclusions Our findings revealed that SNHG1 and C2orf48 possess potential prognostic value and should be considered as possible biomarkers for predicting clinical outcomes for patients with liver cancer.

Abstract
The present study aimed to examine the molecular marker associated with the therapy and prognosis of hepatocellular carcinoma (HCC), and further investigate the association between its expression and the clinicopathological features of HCC. To select the core genes closely associated with HCC, differentially expressed genes (DEGs) were analyzed and screened from Gene Expression Omnibus datasets (GSE 36376) using a bioinformatics approach. Tumor and adjacent tissues were collected form 112 patients of HCC who were treated by radical resection. The expression levels of carbonic anhydrase II (CA2) in the tumor and adjacent tissues were determined using reverse transcription-quantitative polymerase chain reaction analysis and immunohistochemistry. The χ2 test was applied for observing the association between the expression of CA2 and clinicopathological features of patients with HCC. The effects of the expression of CA2 on the patients' overall survival (OS) and disease-free survival (DFS) were examined via Kaplan-Meier analysis. A total of 83 DEGs were screened and analyzed using gene network analysis, among which CA2 had direct interactions with more than one disease gene of HCC. The results of immunohistochemistry showed that CA2 was expressed at a lower level in the tumor tissues compared with the adjacent tissues (t=3.012, P=0.010). Single factor analysis revealed that the mRNA expression of CA2 was able to predict the recurrence of HCC, and was significantly associated with α-fetoprotein (AFP), microvascular invasion, tumor-node-metastasis (TNM) staging, and recurrence (P<0.05). The expression levels of AFP, CA2 and TNM staging were confirmed to be independent prognostic factors of HCC (P<0.05). Kaplan-Meier analysis demonstrated that the group with a high expression of CA2 showed increased DFS and OS, compared with the low expression group (P<0.05). These findings indicated that elevated CA2 increased DFS and OS of HCC, which suggested that CA2 may be a potential target for HCC therapy.

Abstract
Aims: Activin A receptor type 2A (ACVR2A) is a membrane receptor in the transforming growth factor- beta (TGF-β signaling pathway, which is involved in the regulation of cell proliferation, migration, and apoptosis. The aim of this study was to examine the expression profiles and biological functions of ACVR2A in colon cancer. Methods: ACVR2A expression was investigated using the GSE39582 database and two validation cohorts. An in vitro study of cell proliferation and migration of human colon cell lines was also performed. Results: In the GSE39582 database (n= 497), expression of ACVR2A mRNA was identified as a prognostic factor by linear regression analysis. In one validation cohort of 15 patients with stage IV cancer, the mRNA expression of ACVR2A was significantly reduced in metastatic lesions and primary tumors compared with adjacent normal controls (P = 0.001). In another validation cohort of tissue microarray (TMA) consisting of 193 cases, reduced ACVR2A protein expression correlated with advanced N stage (P = 0.001) and positive lymphovascular invasion (P = 0.005). Strong correlations between low ACVR2A mRNA or protein expression and worse survival were also observed in the GSE39582 database and the TMA validation cohort (all P < 0.05). Moreover, our in vitro studies showed a remarkable increase in cell migration in ACVR2A knockdown cells. Conclusions: Our findings indicate that loss of ACVR2A has an important role in cancer progression and distant metastasis and may serve as a prognostic marker in patients with colon cancer.

The expression profiles and biological functions of ACVR2A in colon cancer is largely unknown so far. Methods: ACVR2A expression was investigated using GSE39582 database and two validation cohorts. The in vitro study of the cell proliferation and migration of human colon cell lines was also performed. Results: In GSE39582 database (n = 497), lower mRNA expression of ACVR2A was identified as an inferior prognostic factor by linear regression analysis. In one validation cohort of 15 stage IV patients, the mRNA expression of ACVR2A was significantly reduced in metastatic lesions and primary tumors compared with adjacent normal controls (P = 0.001). In another validation cohort of tissue microarray (TMA) cohort consisting 193 cases, reduced ACVR2A expression was correlated with advanced N stage (P = 0.001) and positive lymphovascular invasion (P = 0.005).

Abstract
BACKGROUND As a disconnection syndrome, schizophrenia has shown impaired resting-state functional connectivity (rsFC) in the orbitofrontal cortex (OFC); however, the OFC is a rather heterogeneous region and the rsFC changes in the OFC subregions remain unknown. METHOD A total of 98 schizophrenia patients and 102 healthy controls underwent resting-state functional MRI using a sensitivity-encoded spiral-in imaging sequence (SENSE-SPIRAL) to reduce susceptibility-induced signal loss and distortion. The OFC subregions were defined according to a previous parcellation study that divided the OFC into the anterior (OFCa), medial (OFCm), posterior (OFCp), intermediate (OFCi), and lateral (OFCl) subregions. The rsFC was compared using two-way repeated-measures ANOVA. RESULTS Whether or not global signal regression, compared with healthy controls, schizophrenia patients consistently exhibited decreased rsFC between the left OFCi and the left middle temporal gyrus and the right middle frontal gyrus (MFG), between the right OFCi and the right MFG and the left inferior frontal gyrus, between the right OFCm and the middle cingulate cortex and the left Rolandic operculum. These rsFC changes still remained significant even after cortical atrophy correction. CONCLUSIONS These findings suggest a selective functional disconnection of the OFC subregions in schizophrenia, and provide more precise information about the functional disconnections of the OFC in this disorder.

Abstract
Negative lymph node (NLN) count has been validated as a protective predictor in various cancers after radical resection. However, the prognostic value of NLN count in the setting of stage IV gastric cancer patients who have received palliative resection has not been investigated. Surveillance, Epidemiology, and End Results Program (SEER)-registered gastric cancer patients were used for analysis in this study. Kaplan-Meier survival curves and multivariate Cox proportional hazards model were used to assess the risk factors for patients’ survivals. The results showed that NLN count and N stage were independently prognostic factors in patients with stage IV gastric cancer after palliative surgery (P< 0.001). X-tile plots identified 2 and 11 as the optimal cutoff values to divide the patients into high, middle and low risk subsets in term of cause-specific survival (CSS). And NLN count was proved to be an independently prognostic factor in multivariate Cox analysis (P< 0.001). The risk score of NLN counts demonstrated that the plot of hazard ratios (HRs) for NLN counts sharply increased when the number of NLN counts decreased. Collectively, our present study revealed that NLN count was an independent prognostic predictor in stage IV gastric cancer after palliative resection. Standard lymph node dissection, such as D2 lymphadectomy maybe still necessary during palliative resection for patients with metastatic gastric cancer.

Abstract
OBJECTIVE To explore the risk factors and prognosis of No.8p lymph node metastasis in cases with advanced gastric cancer. METHODS Clinicopathological and follow-up data of 790 cases with advanced gastric cancer undergoing gastrectomy (including No.8p lymphadenectomy) from October 2003 to October 2013 in Fujian Provincial Tumor Hospital were analyzed retrospectively. Patients receiving neoadjuvant chemotherapy were excluded. Associations of No.8p lymph node metastasis with clinicopathological characteristics and metastasis in other regional lymph node were analyzed. Prognostic difference between positive No.8p group and negative No.8p group was examined. RESULTS Positive No.8p lymph node was found in 93 cases (11.8%) among 790 cases with advanced gastric cancer. Univariate analysis showed that gender [male 9.8%(56/572) vs. female 17.0%(37/218), P=0.005], preoperative CEA level [<5 μg/L 28.0%(61/218) vs. ≥5 μg/L 5.6%(32/572), P=0.005], tumor size[diameter <5 cm 3.8%(13/346) vs. ≥5 cm 18.0%(80/445), P=0.000], tumor location [gastric fundus and cardiac 10.7% (26/244) vs. gastric body 13.5% (30/222) vs. gastric antrum 10.1% (31/308) vs. total gastric 37.5%(6/16), P=0.007], Borrmann staging [type II( 1.9%(4/211) vs. type III( 11.6% (54/464) vs. type IIII( 30.4%(35/115), P=0.000], tumor differentiation [high 0/8 vs. moderate 6.7%(25/372) vs. low 16.6%(68/410), P=0.000], T staging [T2 2.4%(4/170) vs. T3 13.1%(35/267) vs. T4 15.3%(54/353), P=0.000], N staging [N0 0 (0/227) vs. N1 2.2%(5/223) vs. N2 15.2%(26/171) vs. N3 36.7%(62/169), P=0.000] were closely associated with the No.8p lymph node metastasis. Multivariate analysis that revealed gender (OR=1.762, 95%CI: 1.020-3.043), tumor size (OR=1.107, 95%CI: 1.020-1.203), N staging (OR=4.093, 95%CI: 2.929-5.718), tumor differentiation (OR=1.782, 95%CI:1.042-3.049), and metastasis in No.8a(OR=5.370, 95%CI: 3.425-8.419), No.3(OR=1.127, 95%CI:1.053-1.206), No.6(OR=1.221,95%CI: 1.028-1.450), No.7(OR=2.149, 95%CI: 1.711-2.699), No,11p(OR=2.085, 95%CI: 1.453-2.994), No.14v(OR=2.604, 95%CI: 1.038-6.532) group lymph nodes were the independent risk factors of No.8p lymph node metastasis. One-year, 3-year and 5-year survival rates in positive No.8p group were 85.7%, 47.5% and 22.6%, and those in negative No.8p group were 96.2%, 82.5% and 70.3% respectively, whose differences were significant (χ2=109.767, P<0.05). CONCLUSIONS Metastasis in Np.8p lymph nodes is an important factor affecting the prognosis of patients with advanced gastric cancer. In patients with female gender, tumor diameter ≥5 cm, preoperative late N staging, low tumor differentiation or metastasis in No.8a, No.3, No.6, No.7, No.11p, No.14v group lymph nodes, thorough clean rance of No.8p group lymph node should be considered.

Abstract
OBJECTIVE To evaluate the clinicopathologic characteristics and prognostic difference of gastric stump cancer between non-anastomotic site and anastomotic site. METHODS Clinicopathologic data of 149 patients with gastric stump cancer undergoing operation (radical resection and palliative resection) in our department from January 1999 to June 2015 were analyzed retrospectively. Gastric stump cancer was defined as a primary carcinoma detected in the remnant stomach more than 5 years after subtotal gastrectomy for a benign disease(87 cases) or over 10 years after radical subtotal gastrectomy for a malignant disease (62 cases). Patients were divided into the anastomotic site group (72 cases) and the non-anastomotic site group (77 cases) according to tumor sites within the remnant stomach. Clinicopathologic characteristics, operative data, lymph node metastasis and prognosis were compared between the two groups. RESULTS Compared with non-anastomotic site group, the T stage, N stage and TNM stage were later in the anastomotic site group. Number of case of T1, T2, T3, and T4 stage in anastomotic site group was 1(1.4%), 2 (2.8%), 17(23.6%) and 52(72.2%), while such number in non-anastomotic site group was 8(10.4%), 10(13.0%), 27(35.1%) and 32(41.6%) respectively(χ2=17.665, P=0.001). Number of case of N0, N1, N2, and N3 in anastomotic site group was 28 (38.9%), 10 (13.9%), 23 (31.9%) and 11 (15.3%), while such number in non-anastomotic site group was 55 (71.4%), 10 (13.0%), 7 (9.1%) and 5 (6.5%) respectively(χ2=19.421, P=0.000). Number of case of stage I(, II(, III( and IIII( in anastomotic site group was 3(4.2%), 10(13.9%), 47(65.3%) and 12(16.7%), while such number in non-anastomotic site group was 16(20.8%), 40 (51.9%), 15(19.5%) and 6(7.8%) respectively(χ2=45.294, P=0.000). The histology and Borrmann classification were worse in anastomotic site group. Anastomotic site group had 19 cases(26.4%) of good differentiation and 53 cases(73.6%) of bad differentiation, while non-anastomotic site group had 43 cases (55.8%) of well-differentiated and 34 cases (44.2%) of poorly-differentiated tumors respectively(χ2=13.287, P=0.000). Anastomotic site group had 3 cases (4.2%) of Borrmann I(, 17 cases (23.6%) of Borrmann II(, 47 cases(65.3%) of Borrmann III( and 5 cases (6.9%) of Borrmann IIII(, while non-anastomotic site group had 18 cases (23.4%) of Borrmann I(, 16 cases (20.8%) of Borrmann II(, 34 cases (50.6%) of Borrmann III( and 4 cases (5.2%) of Borrmann IIII( respectively(χ2=11.445, P=0.010). Compared with non-anastomotic site group, anastomotic site group had a lower curative resection rate [63.9% (46/72) vs. 89.6% (69/77), χ2=13.977, P=0.000], a higher combined organ resection rate [33.3% (24/72) vs. 16.9% (13/77), χ2=5.394, P=0.020] and a more metastatic lymph nodes (4.3±4.9 vs. 1.9±3.6, t=3.478, P=0.000). The lymph node metastasis rates of No.4, No.10 and jejunal mesentery root lymph node in anastomotic site group and non-anastomotic site group were 15.3% (11/72) and 5.2% (4/77)(χ2=4.178, P=0.041), 9.7% (7/72) and 1.3% (1/77) (χ2=5.196, P=0.023), and 25.0% (18/72) and 3.9% (3/77)(χ2=13.687, P=0.000), respectively. Median followed up of all the patients was 37(2 to 154) months and the overall 5-year survival rate was 44.1%. The 5-year survival rate was 33.1% in anastomotic site group and 55.2% in non-anastomotic site group, and the difference was statistically significant between two groups (P=0.015). In the subgroup analysis according to the histology differentiation, the 5-year survival rate of patients with well-differentiation was not significantly different between two groups (43.7% vs. 56.2%, P=0.872), but the 5-year survival rate of patients with bad differentiation in anastomotic site group was significantly lower than that in non-anastomotic site group(29.8% vs. 53.8%, P=0.029). CONCLUSION Gastric stump cancer locating in anastomotic site indicates worse differentiation histology, higher lymph node metastasis rate, lower curative resection rate and poorer prognosis.

Abstract
With the aim of gathering temporal trends on bacterial epidemiology and resistance from multiple laboratories in China, the CHINET surveillance system was organized in 2005. Antimicrobial susceptibility testing was carried out according to a unified protocol using the Kirby-Bauer method or automated systems. Results were analyzed according to Clinical and Laboratory Standards Institute (CLSI) 2014 definitions. Between 2005 and 2014, the number of bacterial isolates ranged between 22,774 and 84,572 annually. Rates of extended-spectrum β-lactamase production among Escherichia coli isolates were stable, between 51.7 and 55.8%. Resistance of E. coli and Klebsiella pneumoniae to amikacin, ciprofloxacin, piperacillin/tazobactam and cefoperazone/sulbactam decreased with time. Carbapenem resistance among K. pneumoniae isolates increased from 2.4 to 13.4%. Resistance of Pseudomonas aeruginosa strains against all of antimicrobial agents tested including imipenem and meropenem decreased with time. On the contrary, resistance of Acinetobacter baumannii strains to carbapenems increased from 31 to 66.7%. A marked decrease of methicillin resistance from 69% in 2005 to 44.6% in 2014 was observed for Staphylococcus aureus. Carbapenem resistance rates in K. pneumoniae and A. baumannii in China are high. Our results indicate the importance of bacterial surveillance studies.

Abstract
Genetic and epigenetic pathways are not independent in colorectal cancer (CRC) carcinogenesis. We aimed to determine the influence of various molecular features on Chinese patients' colon cancer-specific survival (CCSS). Various genetic and epigenetic modifications were detected in paired tumor and normal mucosa tissue samples. The prognostic variables regarding patient CCSS were determined. Overall, 127 patients, including 83 males and 44 females, completed a median follow-up of 65 (3–85) months. A mean LINE-1 methylation rate of 64.62% (range, 9.45–86.93) was observed. Hypermethylation at the hMLH1 gene promoter was detected in 26 (20.47%) patients. KRAS was mutated in 52 (40.94%) patients. Sixteen (12.60%) patients were confirmed as microsatellite instability (MSI)-High, and 76 (59.84%) were found to have loss of heterozygosity at 18q. The LINE-1 methylation level, MSI status, perineural invasion and distant metastases were confirmed as independent prognostic factors for patient CCSS. A stratified survival analysis further revealed that certain subgroups of patients with LINE-1 hypomethylation had significantly worse survival (all p < 0.05). Our data revealed that both genetic and epigenetic abnormalities can concurrently exist during colonic tumorigenesis. As a global epigenetic change, LINE-1 hypomethylation in normal colon mucosa might be associated with a worse outcome in certain Chinese patients with colon cancer.

Abstract
BACKGROUND High-quality images can be readily captured during laparoscopic colon surgery, but there are no guidelines for documentation of these video data or how to best measure surgical quality from an operative video. This study evaluates the feasibility and compliance in documenting key steps during laparoscopic right hemicolectomy and sigmoid colectomy. MATERIALS AND METHODS A retrospective review of previously recorded videos of patients undergoing laparoscopic right hemicolectomy or sigmoid colectomy from September to December 2011 in a single institution was performed. Patients' demographics, intraoperative features, postoperative complications, and variables for video recording and editing were collected. Compliance of key surgical steps was assessed using a checklist by two independent surgeons. RESULTS Sixteen laparoscopic operations (seven right hemicolectomies and nine sigmoid colectomies) were recorded. Twelve (75%) were laparoscopic-assisted, and four (25%) were hand-assisted laparoscopic operations. Compliance with key surgical steps in laparoscopic right hemicolectomy and sigmoid colectomy was demonstrated in the majority of patients, with steps ranging in compliance from 42.9% to 100% and from 77.8% to 100%, respectively. The edited video had a median duration of 3 minutes 47 seconds (range, 1 minute 44 seconds-5 minutes 38 seconds) with a production time of nearly 1 hour and a resolution of 1440 × 1080 pixels. CONCLUSIONS Key surgical steps during laparoscopic right hemicolectomy and sigmoid colectomy can be documented and edited into a short representative video. Standardization of this process should allow video documentation to improve quality in laparoscopic colon surgery.

Abstract
The tumor microenvironment composites a mixture of immune lymphoid cells, myeloid cells, stromal cells with complex cytokines, as well as numerous lymphovascular vessels. Colorectal cancer (CRC) is a common malignancy and one of the leading causes of tumor-related death in the United States and worldwide. The immune status in the tumor microenvironment contributes to the survival of a patient with CRC. Regulatory T cells (Tregs) are considered a key factor in immune escape and immunotherapy failure among cancer patients. The transcription factor forkhead box P3 (FOXP3) is a crucial intracellular marker and also a key developmental and functional factor for CD4+CD25+ Tregs. Tregs are correlated with survival in various human neoplasms, and elevated proportions of Tregs are usually associated with unfavorable clinical outcomes. However, the role of Tregs in CRC remains controversial. High densities of tumor-infiltrating Tregs in CRC patients are reported to be correlated with worse or better outcomes. And Tregs may not be predictive of prognosis after resection of the primary tumor. The exact explanations for these discordant results remain unclear. The heterogeneous instincts of cell phenotype, gene expression, and functional activities of Tregs may partly contribute this contrasting result. Furthermore, the lack of a robust marker for identifying Tregs or due to the different techniques applied is also account. The Treg-specific demethylated region (TSDR) was recently reported to be a specific epigenetic marker for natural Tregs (nTregs), which can stably express FOXP3. The FOXP3-TSDR demethylation assay may be an promising technique for CRC-related nTregs studies.

Abstract
The transanal eversion and prolapsing technique is a well-established procedure, and can ensure an adequate distal margin for patients with low rectal neoplasms. Potential leakage risks, however, are associated with bilateral dog ear formation, which results from traditional double-stapling anastomosis. The authors determined the feasibility of combining these techniques with a commercial stapling set to achieve a nondog ear (end-to-end) anastomosis for patients with mid- and distal rectal neoplasms. Patients with early-stage (c/ycT1-2N0), mid- to distal rectal neoplasms and good anal sphincter function were included in this study. Laparoscopic low anterior resection was performed with a standard total mesorectal excision technique downward to the pelvic floor as low as possible. The bowel was resected proximal to the lesion with an endoscopic linear stapler. An anvil was inserted extracorporeally into the proximal colon via an extended working pore. The distal rectum coupled with the lesion was prolapsed and everted out of the anus. The neoplasm was resected with a sufficient margin above the dentate line under direct sight. A transrectal anastomosis without dog ears was performed intracorporeally to reconstitute the continuity of the bowel. Eleven cases, 6 male and 5 female patients, were included in this study. The mean operative time was 191 (129-292) minutes. The mean blood loss was 110 (30-300) mL. The median distal margin distance from the lower edge of the lesion to the dentate line was 1.5 (0.5-2.5) cm. All the resection margins were negative. Most patients experienced uneventful postoperative recoveries. No patient had anastomotic leak. Most patients had an acceptable stool frequency after loop ileostomy closure. Our preliminary data demonstrated the safety and feasibility of achieving a sound anastomosis without risking potential anastomotic leakage because of dog ear formation.

Abstract
Background High expression of the long non-coding RNA nuclear-enriched abundant transcript 1 (NEAT1) in whole blood has been reported in colorectal cancer patients; however, its’ clinical significance and origin are unclear. We evaluated the diagnostic and prognostic value, and origin of whole blood NEAT1 in colorectal cancer. Methods Expression of NEAT1 variants, NEAT1_v1 and NEAT1_v2 were determined using real-time quantitative PCR. The diagnostic value of whole blood NEAT1 expression was evaluated in test (n = 60) and validation (n = 200) cohorts of colorectal cancer patients and normal controls (NCs). To identify the origin of NEAT1, its expression was analyzed in blood, matched primary tumor tissues, para-tumor tissues, metastatic tissues, and also immune cells from patients or NCs. Function of NEAT1 in colorectal cell lines was also assessed. The correlation of NEAT1 expression with clinical outcomes was assessed in 191 patients. Results Whole blood NEAT1 expression was significantly higher in colorectal cancer patients than in NCs. NEAT1_v1 and NEAT1_v2 expression were highly accurate in distinguishing colorectal cancer patients from NCs (area under the curve: 0.787 and 0.871, respectively). Knockdown of NEAT1_v1 in vitro could inhibit cell invasion and proliferation, while knockdown of NEAT1_v2 promoted cell growth. However, whole blood expression was not correlated with matched tissues. An elevated expression was seen in neutrophils from CRC patients. Furthermore, high expression of NEAT1_v1 was correlated with worse overall survival. In contrast, high expression of NEAT1_v2 alone was correlated with better overall survival. Conclusion Whole blood NEAT1 expression is a novel diagnostic and prognostic biomarker of overall survival in colorectal cancer. Elevated NEAT1 may derive from neutrophils.

Abstract
Schizophrenia patients have shown altered resting-state functional connectivity (rsFC) of the cingulate cortex; however, it is unknown whether rsFCs of the cingulate subregions are differentially affected in this disorder. We aimed to clarify the issue by comparing rsFCs of each cingulate subregion between healthy controls and schizophrenia patients. A total of 102 healthy controls and 94 schizophrenia patients underwent resting-state functional magnetic resonance imaging with a sensitivity-encoded spiral-in imaging sequence to reduce susceptibility-induced signal loss and distortion. The cingulate cortex was divided into nine subregions, including the subgenual anterior cingulate cortex (ACC), areas 24 and 32 of the pregenual ACC, areas 24 and 32 of the anterior mid-cingulate cortex (aMCC), posterior MCC (pMCC), dorsal (dPCC) and ventral (vPCC) posterior cingulate cortex (PCC) and retrosplenial cortex (RSC). The rsFCs of each cingulate subregion were compared between the two groups and the atrophy effect was considered. Results with and without global signal regression were reported. Most cingulate subregions exhibited decreased rsFCs in schizophrenia after global signal regression (GSR). Without GSR, only increased rsFC was found in schizophrenia, which primarily restricted to the aMCC, PCC and RSC. Some of these increased rsFCs were also significant after GSR. These findings suggest that GSR can greatly affect between-group differences in rsFCs and the consistently increased rsFCs may challenge the functional disconnection hypothesis of schizophrenia.

Abstract
Forkhead box protein C2 (FOXC2) plays a vital role in carcinogenesis; however, its significance and prognostic value in colon cancer remain unclear. In this study, FOXC2 expression was analyzed in a tissue microarray (TMA) containing 185 samples of primary colon cancer tumor samples and in human colon cancer cell lines. The effect of FOXC2 on cell proliferation, tumorigenesis, and metastasis was examined in vitro and in vivo. FOXC2 was overexpressed in human colon cancer cells and tissues, and correlated with colon cancer progression and patient survival. Functional study demonstrated that FOXC2 promoted cell growth, cell migration, and tumor formation in nude mice, whereas knockdown of FOXC2 by short hairpin RNA (shRNAs) significantly suppressed cell growth, cell migration and tumor formation. Further study found that FOXC2 enhanced AKT activity with subsequent GSK-3β phosphorylation and Snail stabilization, and then induced epithelial-mesenchymal transition (EMT) and promoted tumor invasion and metastasis. Collectively, FOXC2 promotes colon cancer metastasis by facilitating EMT and acts as a potential prognostic factor and therapeutic target in colon cancer.

Abstract
636 Background: Distant metastasis remains the most common causes to death of colon cancer. Thus it is crucial to identify the molecular markers associated with the progression and metastasis of this disease. Recent evidence for overexpression of FOXC1 in several types of human cancer suggests that it might play a key role in tumor biology. However, the clinical significance of FOXC1 signaling in human colon cancer pathogenesis remains unknown. Methods: We investigated FOXC1 expression in 203 cases of primary colon cancer and matched normal colon tissue and lymph node matastasis in a tissue array. The underlying mechanisms of altered FOXC1 expression and the impact of this altered expression on colon cancer growth and metastasis was explored both in vitro and in vivo. Results: We found elevated expression of FOXC1 protein in cancereous tissue and lymph node metastases than adjacent normal colonic tissues. Overexpression of FOXC1 was associated with higher clinical stage, T stage, lymph node metastasis and presence of distant metastasis. FOXC1 served as an independent prognostic marker whose expression levels correlated with poorer metastasis-free survival (MFS) and poorer overall survival (OS). A Cox proportional hazards model revealed that FOXC1 expression was an independent prognostic factor in multivariate analysis. Experimentally, FOXC1 silencing significantly inhibited the growth and metastasis of colon cancer cells in vitro and in vivo. FOXC1 transcriptionally regulates SNAIL1, contributing to epithelial-to-mesenchymal transition and metastasis in colon cancer cells. Conclusions: Dysregulated expression of FOXC1 may play a critical role in colon cancer progression and metastasis. Thus, FOXC1 may serve as a candidate prognostic biomarker and therapeutically targeted.

Abstract
BACKGROUND We sought to determine the prognostic role of tumor size on cause-specific survival (CSS) of patients with stage IIA colon cancer. METHODS Surveillance, Epidemiology and End Results (SEER) database was utilized to identify patients with stage IIA colorectal cancer (examined lymph nodes ≥12) diagnosed from 1988 to 2003. The prognostic effect of tumor size on CSS was evaluated by univariate and multivariate analyses. RESULTS A total of 8775 patients were enrolled in the analysis. The median follow-up time was 109 months. As determined by minimal P value method, tumor sizes of 2.5 and 6.0 cm were used as optimal cutoff value to divide the cohort. The 8-year CSS of colon cancer with tumor sizes ≤2.5, 2.6-6.0, and >6.0 cm was 81.6, 86.2, and 86.7% respectively (P = 0.003). In the multivariate analysis of colon cancer, using ≤2.5-cm tumors as reference, decreased hazard ratio (HR) of CSS was observed in 2.6-6.0 cm (HR, 0.736; 95% confidence interval (CI), 0.599-0.905; P = 0.004) and >6.0 cm (HR, 0.770; 95% CI, 0.619-0.958; P = 0.019) tumors. CONCLUSIONS In stage IIA colon cancer, small tumor size represented a subset with decreased CSS. Further studies are merited to validate the unfavorable prognostic role of small tumor size in stage IIA colon cancer.

Abstract
Recent studies indicated that preoperative radiotherapy significantly reduces the lymph nodes (LNs) harvest from patients with rectal cancer. This may weaken the prognostic value of current standard of LNs retrieval (≥12 LNs). This study investigates the prognostic impact of the LN counts on pathologically LN-negative (ypN0) after preoperative radiotherapy for patients with rectal cancer.Surveillance, Epidemiology and End Results (SEER) registered nonmetastatic rectal cancer patients diagnosed between 1998 and 2005 were included in this study. Optimal cutoff value for number of LNs retrieved was determined by X-tile program. Log-rank tests were adopted to compare the rectal cause specific survival (RCSS) for ypN0 patients using separated cutoff value of LN counting from 2 to 20. Correlation between LN count and tumor regression was investigated in an additional 221 patients from Fudan University Shanghai Cancer Center (FUSCC).The results showed that there were fewer number of LNs examined in patients with preoperative radiotherapy than those without (8.9 vs 10.9, P < 0.001). X-tile program identified the difference in survival was most significant (maximum of χ log-rank values) for the number 4. And 5-year RCSS increased accordingly with the cutoff values ranging from 4 to 15, which were confirmed as optimal cutoff and validated as independent prognostic factors in multivariate regression analysis (χ = 50.65, P < 0.001). Patients in FUSCC set were found to have fewer LNs retrieval in group of good tumor regression than in that of poor one (P = 0.01).These results confirmed the reduced number of LN retrieval in patients with rectal cancer treated with preop-RT. LN count is still an independently prognostic factor for ypN0 rectal cancer.

Abstract
Previous reports have suggested that human CD4(+) CD25(hi)FOXP3(+) T regulatory cells (Tregs) have functional plasticity and may differentiate into effector T cells under inflammation. The molecular mechanisms underlying these findings remain unclear. Here we identified the residue serine 422 of human FOXP3 as a phosphorylation site that regulates its function, which is not present in murine Foxp3. PIM1 kinase, which is highly expressed in human Tregs, was found to be able to interact with and to phosphorylate human FOXP3 at serine 422. T cell receptor (TCR) signaling inhibits PIM1 induction, whereas IL-6 promotes PIM1 expression in in vitro expanded human Tregs. PIM1 negatively regulates FOXP3 chromatin binding activity by specifically phosphorylating FOXP3 at Ser(422). Our data also suggest that phosphorylation of FOXP3 at the Ser(418) site could prevent FOXP3 phosphorylation at Ser(422) mediated by PIM1. Knockdown of PIM1 in in vitro expanded human Tregs promoted FOXP3-induced target gene expression, including CD25, CTLA4, and glucocorticoid-induced tumor necrosis factor receptor (GITR), or weakened FOXP3-suppressed IL-2 gene expression and enhanced the immunosuppressive activity of Tregs. Furthermore, PIM1-specific inhibitor boosted FOXP3 DNA binding activity in in vitro expanded primary Tregs and also enhanced their suppressive activity toward the proliferation of T effector cells. Taken together, our findings suggest that PIM1 could be a new potential therapeutic target in the prevention and treatment of human-specific autoimmune diseases because of its ability to modulate the immunosuppressive activity of human Tregs.

Abstract
BACKGROUND The influence of natural regulatory T cells (nTregs) on the patients with colon cancer is unclear. Demethylated status of the Treg-specific demethylated region (TSDR) of the FOXP3 gene was reported to be a potential biomarker for the identification of nTregs. METHODS The demethylation rate of the TSDR (TSDR-DMR) was calculated by using methylation-specific quantitative polymerase chain reaction (MS-qPCR) assay. The expression of TSDR-DMR and FOXP3 mRNA was investigated in various colorectal cancer cell lines. A total of 130 colon carcinoma samples were utilized to study the DMR at tumor sites (DMRT) and adjacent normal tissue (DMRN). The correlations between DMRs and clinicopathological variables of patients with colon cancer were studied. RESULTS The TSDR-DMRs varied dramatically among nTregs (97.920 ± 0.466%) and iTregs (3.917 ± 0.750%). Significantly, DMRT (3.296 ± 0.213%) was higher than DMRN (1.605 ± 0.146%) (n = 130, p = 0.000). Higher DMRN levels were found in female patients (p = 0.001) and those with distant metastases (p = 0.017), and were also associated with worse recurrence-free survival in non-stage IV patients (low vs. high, p = 0.022). However, further Cox multivariate analysis revealed that the FOXP3-TSDR status does not have prognostic value. CONCLUSION MS-qPCR assays of FOXP3-TSDR can efficiently distinguish nTregs from non-nTregs. Abnormal recruitment of nTregs occurs in the local tumor microenvironment. Infiltration of tissue-resident nTregs may have a negative role in anti-tumor effects in patients with colon cancer; however, this role is limited and complicated.

Abstract
Long noncoding RNAs (lncRNAs) have recently emerged as a major class of regulatory molecules, which were involved in a broad range of biological processes and complex diseases. Research on lncRNAs may shed light on tumorigenesis and progression of colorectal cancer (CRC). The purpose of the present study was to identify lncRNAs correlated with CRC and then investigate their potential functions. We selected 92 patients for this prospective study and then collected the tumor samples and clinical records. First, the global lncRNA expression profiles in tumor and adjacent normal tissues of patients with non-metastatic CRC and patients with metastatic CRC were measured by microarray assay. Then, a noteworthy lncRNAs RP11-462C24.1 whose function was previously unknown was explored in detail on the aspect of the association of its expression level and clinicopathological features of CRC and patients' survival. We found that RP11-462C24.1 expression level was lower in cancer tissues compared with adjacent normal samples (P < 0.001). Furthermore, its expression level was lower in CRC patients with metastasis than those without metastasis (P = 0.049). That is, RP11-462C24.1 expression level decreased as the malignant degree of CRC increased. In addition, low expression of RP11-462C24.1 significantly correlated with more distant metastasis (P = 0.011). The areas under ROC curves were 0.78 and 0.65 for RP11-462C24.1, distinguishing CRC from normal tissue and distinguishing CRC without metastasis from CRC with metastasis, respectively. Multivariate analysis identified that RP11-462C24.1 was an independent predictor for patients prognosis (P = 0.005). Furthermore, Kaplan-Meier analysis showed that patients with low expression of RP11-462C24.1 had a poor disease-free survival (P < 0.001). This is the first study that correlates RP11-462C24.1 expression profile with malignancy grade in human CRC. Our results showed that RP11-462C24.1 could be a potential novel prognostic marker for CRC, and thus, provided a new strategy for CRC diagnosis. Meanwhile, our findings indicated the potential roles of RP11-462C24.1 in tumorigenesis and progression of CRC, which gave a clue for future studies.

Abstract
PURPOSE The purpose of the study was to evaluate the feasibility and safety of performing laparoscopic intestinal surgery using local anesthesia and intravenous sedation with instruments <3 mm in diameter. METHODS Porcine model with acute (n = 2) and the survival studies (n = 8): all female pigs, weight (median 36.4 kg, range 33.2-38.4 kg). Surgeries were performed using only intravenous sedation with ketamine-midazolam and local anesthetic infiltration at the sites of trocar insertion, with airway protection. CO2 pneumoperitoneum was maintained using pressure of 3 to 5 mm Hg. Commercially available instruments, sizes <3 mm in diameter were used. Surgical steps were as follows: (a) exploration of all quadrants of the abdomen and pelvis, (b) "running" the entire length of small bowel, (c) dissection of bowel attachments to the peritoneal sidewall, and (d) creating a 2.5 cm enterotomy in the colon and suture repair of this defect. RESULTS All 10 surgeries were completed successfully. Animals tolerated the procedure well, with no requirement of intubation. There were no decrements in vital signs during pneumoperitoneum or surgery. Despite spontaneous respiration movements, all planned surgical maneuvers were feasible. The median length of operations was 74 minutes (range 56-165 minutes). All survival animals had an uneventful recovery; there were no infectious complications, oral intake and bowel function returned within 24 hours. CONCLUSIONS It appears feasible and safe to perform simple laparoscopic intestinal procedures using instruments <3 mm in diameter and low CO2 insufflation pressure under local anesthesia and intravenous sedation. This methodology holds promise in the development of new approaches to intestinal surgery and disease diagnosis.

Abstract
Objective To compare the long-term survival of colorectal cancer (CRC) in young patients with elderly ones. Methods Using Surveillance, Epidemiology, and End Results (SEER) population-based data, we identified 69,835 patients with non-metastatic colorectal cancer diagnosed between January 1, 1988 and December 31, 2003 treated with surgery. Patients were divided into young (40 years and under) and elderly groups (over 40 years of age). Five-year cancer specific survival data were obtained. Kaplan-Meier methods were adopted and multivariable Cox regression models were built for the analysis of long-term survival outcomes and risk factors. Results Young patients showed significantly higher pathological grading (p<0.001), more cases of mucinous and signet-ring histological type (p<0.001), later AJCC stage (p<0.001), more lymph nodes (≥12 nodes) dissected (p<0.001) and higher metastatic lymph node ratio (p<0.001). The 5-year colorectal cancer specific survival rates were 78.6% in young group and 75.3% in elderly group, which had significant difference in both univariate and multivariate analysis (P<0.001). Further analysis showed this significant difference only existed in stage II and III patients. Conclusions Compared with elderly patients, young patients with colorectal cancer treated with surgery appear to have unique characteristics and a higher cancer specific survival rate although they presented with higher proportions of unfavorable biological behavior as well as advanced stage disease.

Abstract
BACKGROUND Despite the increasing prevalence of obesity and colonic diseases, the impact of obesity on short-term and oncologic outcomes of laparoscopic colorectal surgery still remains unclear. STUDY DESIGN Seventy-six consecutive obese patients with body mass index (BMI) ≥30 kg/m(2) who underwent laparoscopic colectomy were matched with 76 nonobese patients with BMI <30 kg/m(2). Perioperative parameters and oncologic outcomes were analyzed in the two groups. RESULTS Obesity was associated with greater operative time (obese vs nonobese, 182 ± 59 vs 157 ± 55 min, P = .0084) and multivariate analysis identified BMI (hazard ratio 2.11, 95% confidence interval 0.64-3.56, P = .0049) as an independent predicting factor for operative time together with cancer location (hazard ratio 28.6, 95% confidence interval 14.62-42.51, P < .0001). Obesity had no adverse influence on overall morbidity (25 vs 21%, P = .563), however, or postoperative duration of stay (median 6.0 vs 5.5 days, P = .22). Furthermore, the rate of conversion to open procedure was similar between the two groups (9 vs 9%, P > .99). Regarding oncologic outcomes, there was no statistical difference in overall and disease-free survival between the two groups (5-year overall survival rate 86 vs 89%, P = .72, 5-year disease survival rate 70 vs 77%, P = .70). CONCLUSION Laparoscopic colonic resection, when performed for selected patients, appears to be a safe and reasonable option in obese patients with colon cancer resulting in similar short-term and oncologic outcomes as nonobese patients.

Abstract
AIM The natural history and appropriate management of anastomotic sinus has not been clearly defined. The aim of this study was to evaluate the incidence, management and outcomes of anastomotic sinus. METHOD The medical records of all patients who underwent a low anterior resection (LAR) or an ileal pouch-anal anastomosis (IPAA) with a diverting loop ileostomy (LI) and with contrast enema performed before planned stoma closure between 2001 and 2011 were retrospectively reviewed. The radiological features of the sinus tract, treatment and outcome of anastomotic sinus were studied. RESULTS Twenty patients (8.2%) were found to have anastomotic sinuses out of the total of 244 patients who had undergone LAR (n = 146) or IPAA (n = 98) with LI. Of these, 13 (65%) had prior symptomatic leaks, while seven did not. Twelve patients (60%) were found to have simple sinus tracts, while eight had complex sinuses (associated with either pelvic cavities or severe strictures). Five patients with simple tracts were treated with observation alone. Fifteen patients underwent surgical interventions. Overall, with a median follow-up of 28 (6-73) months, 16 patients (80%) had resolution of their sinuses. All of 12 patients (100%) with simple sinus tracts and four of eight patients (50%) with complex sinuses underwent successful stoma reversals after 8 (3.5-24) months following the initial surgery (P = 0.01). CONCLUSION Patients with simple tracts are significantly more likely to have complete resolution of sinuses than patients with complex sinuses. Persistent sinus associated with either a pelvic cavity or severe stricture despite surgical intervention is likely to lead to a permanent stoma.

Abstract
The purpose of this study was to investigate the genetic characteristics of fluoroquinolone-nonsusceptible Streptococcus pneumoniae clinical isolates in China. A total of 377 S. pneumoniae clinical isolates, including 307 pediatric strains and 70 adult strains, were collected from eight centers in China. The minimal inhibitory concentrations (MICs) of 10 antimicrobial agents were determined by agar dilution. Multilocus sequence typing (MLST), serotyping, and quinolone resistance-determining region (QRDR) variations were conducted in levofloxacin-nonsusceptible isolates by polymerase chain reaction (PCR)-based methods. Seven levofloxacin-nonsusceptible isolates were found, with an overall resistance rate of 1.9 % (7/377) and 8.6 % (6/70) in adults. Sequence analyses of parC, gyrA, and parE QRDRs in levofloxacin-resistant isolates demonstrated mutations in dual target sites at the hot spots. These seven strains represented multiple clones: two strains were serotype 19F (Taiwan(19F)-14) and MLST clonal complex (CC) 271/320, two were typed as 23F (Spain(23F)-1) and CC81, two were determined as serotype 20B and a new sequence type of ST6935, and one non-serotypeable pediatric strain belonged to a new sequence type of ST6946. Two serotype 19F strains possessed a variety of characteristic alterations of viridans group streptococci in gyrA (Ser114Gly) or parC (Ser52Gly, Asn91Asp). Fluoroquinolone-nonsusceptible S. pneumoniae isolates showed a substantial degree of genetic diversity and belonged to pre-existing epidemic clones together with native clones. S. pneumoniae strains with serotype 20B was recovered for the first time to be associated with levofloxacin resistance in China.

Abstract
OBJECTIVE The current study is to evaluate the effect of thymidylate synthase (TYMS) on lymph node metastasis (LNM) in Chinese colorectal cancer (CRC) patients, and develop potential LNM-associated biomarkers for CRC. DESIGN AND METHODS Differences in TYMS gene expression between primary CRC with LNM (LNM CRC) and without LNM (non-LNM CRC) were assessed using quantitative real-time PCR analysis in 100 Chinese colorectal cancer patients. The relationship between clinicopathological parameters and prognosis of candidate biomarkers was also examined in the experiment. RESULTS TYMS was significantly upregulated in LNM CRC compared with non-LNM CRC, which was confirmed by real-time quantitative polymerase chain reaction. Overexpression of TYMS was significantly associated with LNM (P<0.001), advanced TNM stage (P<0.001), increased 5-year recurrence rate (P<0.001) and decreased 5-year overall survival rate (P<0.001). Univariate and multivariate analyses indicated that TYMS expression was an independent prognostic factor for recurrence and survival of CRC patients (P<0.05). CONCLUSIONS TYMS effect on lymph node metastasis in CRC might serve as a potential biomarker for LNM and a prognostic factor in CRC. Over-expression of TYMS is a predicting factor to the poor outcome in clinical colorectal cancer patients.

Abstract
In contrast to colonoscopy biopsy, which contains several disadvantages such as bleeding, sampling error, crush artifact, and time-consuming pathological procedure, multiphoton microscopy (MPM) enables direct noninvasive visualization of tissue architecture and cell morphology in live tissues without the administration of exogenous contrast agents. We performed a proof-of-principle study to evaluate the feasibility of using MPM to make real-time noninvasive optical diagnosis of colorectal cancer by investigating 30 fresh, unfixed, and unstained full-thickness colorectal specimens. We found that MPM images demonstrated irregular tubular structures, reduced stroma, and cellular and nuclear pleomorphism in the cancerous tissues. Cancer cells, characterized by irregular size and shape, enlarged nuclei, and increased nuclear-cytoplasmic ratio, were clearly observed in MPM images, which were comparable to golden standard hematoxylin-eosin staining images. Our findings showed that MPM had the potential to make real-time noninvasive optical diagnosis of colorectal cancer. With miniaturization and integration of colonoscopy, MPM has a promising future in real-time noninvasive "optical biopsy" for colorectal cancer.

Abstract
[3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone] (MX) and chlorinated acetic acids such as dichlorinated acetic acid (DCA) and trichlorinated acetic acid (TCA) have always been the focus of disinfection by-products (DBPs) studies. In order to find out the influences of reaction time, TOC, chlorine dose, pH and temperature on the formation of MX, DCA and TCA, we extracted fulvic acid (FA) from the sediment of Tai Lake, and conducted simulated chlorination of samples rich in FA. Results showed positive relationship between TOC and the yields of MX, DCA and TCA. But the influences of pH, chlorine dose, reaction time, and temperature are quite complex. The optimal chlorination condition for the formation of MX is pH = 2, T = 45 degrees C, C/Cl2 = 1/4, t = 12 h. Lower pH, longer time, greater chlorine dose can result in greater yield of both DCA and TCA, and there is a strong linear relationship between the formation of DCA and TCA.

Abstract
OBJECTIVE In order to set up intervention measures in preventing injuries. METHODS An analysis on the epidemiological feature of injuries in 9 civic middle and primary schools with 3,988 students involved was carried out in July 1998. RESULTS The results showed that the total rate of 12 kinds of injuries was 50.55%. Among which, 5 kinds of injuries took the first 5 places: injuries from falls (32.15%), knife-cutting or sharp weapon hurt (21.99%) bumps (17.05%) traffic accidents (12.51%) burns and scalds (11.43%). CONCLUSION The rate of injury was related closely with age parent's culture background and the number of children in families, but was not significantly related to sex, parent's occupation and the condition of living with relatives. Strengthening supervision, safety health education and increase awareness on self-protection were the most important points. Some intervention measures were being put into practice.
