Abstract
BACKGROUND Tumor mutational load (TML) has emerged as a potential biomarker for multiple solid tumors. However, data on its prognostic impact on upper gastrointestinal (UGI) cancer are limited. Therefore, the aim of this systematic review and meta-analysis was to assess the prognostic value of TML for the survival of patients with UGI cancer. METHOD A comprehensive search of the PubMed, Embase, Cochrane Library, and Web of Science databases was conducted up to February 13, 2023. Eleven studies met our inclusion criteria. Hazard ratios (HRs) for progression-free survival and overall survival and their 95% confidence intervals (CIs) were calculated. Subsequently, the combined HR and its 95% CI were calculated for UGI tract cancers in the high and low TML groups. I2 statistics and p-values were used to evaluate heterogeneity. Publication bias, sensitivity, and subgroup analyses were performed to determine sources of heterogeneity. RESULTS In total, 932 patients with UGI tract cancer from 11 publications were included. The high TML group treated with immunotherapy showed significantly improved overall survival (HR = 0.68; 95% CI: 0.53, 0.86; p = .001) and progression-free survival (HR = 0.74; 95% CI: 0.58, 0.95; p = .020) compared with the low TML group. CONCLUSION Our study demonstrated that patients with UGI tumors and higher TML have a better prognosis with immunotherapy, suggesting that TML is a promising predictive biomarker for immunotherapy. REGISTRATION The study protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO Registration No: CRD42023405596).

Abstract
Monoubiquitination of FANCD2 is a central step in the activation of the Fanconi anemia (FA) pathway after DNA damage. Defects in the FA pathway centered around FANCD2 not only lead to genomic instability but also induce tumorigenesis. At present, few studies have investigated FANCD2 in tumors, and no pan-cancer research on FANCD2 has been conducted. We conducted a comprehensive analysis of the role of FANCD2 in cancer using public databases and other published studies. Moreover, we evaluated the role of FANCD2 in the proliferation, migration and invasion of lung adenocarcinoma cells through in vitro and in vivo experiments, and explored the role of FANCD2 in cisplatin chemoresistance. We investigated the regulatory effect of FANCD2 on the cell cycle of lung adenocarcinoma cells by flow cytometry, and verified this effect by western blotting. FANCD2 expression is elevated in most TCGA tumors and shows a strong positive correlation with poor prognosis in tumor patients. In addition, FANCD2 expression shows strong correlations with immune infiltration, immune checkpoints, the tumor mutation burden (TMB), and microsatellite instability (MSI), which are immune-related features, suggesting that it may be a potential target of tumor immunotherapy. We further found that FANCD2 significantly promotes the proliferation, invasion, and migration abilities of lung adenocarcinoma cells and that its ability to promote cancer cell proliferation may be achieved by modulating the cell cycle. The findings indicate that FANCD2 is a potential biomarker and therapeutic target in cancer treatment by analyzing the oncogenic role of FANCD2 in different tumors.

Abstract
Lung adenocarcinoma (LUAD) is the most common type of lung cancer. LRP1B was initially identified as a cancer suppressor in several cancers. However, the potential biological phenotypes and molecular mechanisms of LRP1B in LUAD have not been fully investigated. In our study, we showed that the expression of LRP1B in LUAD tissues was lower than that in normal tissues. Knockdown of LRP1B markedly enhanced malignancy of LUAD cells. Genomic analysis indicated that the population expressing low-levels of LRP1B had higher genomic instability, which accounted for a larger proportion of aneuploidy and inflammation subtyping. Enrichment analysis of bulk and cell-line transcriptomic data both showed that the low expression of LRP1B could induce the activation of IL-6-JAK-STAT3, chemokine, cytokine, and other inflammation signaling pathways. Moreover, our findings revealed that knockdown LRP1B enhanced the secretion of IL-6 and IL-8, as confirmed by ELISA assays. Further validation using PCR and WB confirmed that downregulation of LRP1B mRNA significantly upregulated the activity of the IL-6-JAK-STAT3 pathway. Collectively, this study highlights LRP1B as a tumor suppressor gene and reveals that LRP1B knockdown promotes malignant progression in LUAD by inducing inflammation through the IL-6-JAK-STAT3 pathway.

Abstract
Background and Objective As a surgical tool, indocyanine green (ICG) is increasingly used in surgery, especially in gastric and colorectal surgery. The use of ICG fluorescence imaging can improve the accuracy of tumor resection and potentially improve surgical outcomes for cancer patients. However, there are still different opinions or controversies on the application of ICG in the literature and the administration of ICG is still not uniform. In this review, we summarize the current status of its application and ICG administration methods in gastrointestinal cancer and discuss its existing limitations and future research directions. Methods Literature published in the PubMed database from 1969 to 2022 was searched for using the keywords "Indocyanine green or near-infrared imaging or ICG", "gastric cancer", "gastroesophageal junction cancer", and "colorectal cancer" to summarize the main applications of ICG in gastrointestinal cancers. Key Content and Findings ICG guidance can rapidly determine tumor location and save operative time, and can also visualize lymph nodes (LNs) in real-time, helping surgeons to retrieve more LNs for better postoperative staging, but its use in identifying sentinel lymph node (SLN) in gastric cancer (GC) remains controversial due to false negatives. ICG fluorescent angiography has great potential in preventing colorectal anastomotic leakage, but there is a dearth of high-caliber research evidence. In addition, ICG has unique advantages in detecting colorectal liver micrometastasis. Notably, there is still no uniform administration method and dose of ICG. Conclusions In this review, we summarize the current status of ICG application in gastrointestinal cancer, and the current literature suggests that it is safe and effective and has the potential to change the clinical outcome of patients. Therefore, ICG should be routinely used in gastrointestinal cancers to improve the surgical outcomes of patients. In addition, this review summarizes the ICG administration in the literature, and we expect future guidelines to unitize and standardize the administration of ICG.

Abstract
Diffuse type gastric cancer was identified with relatively worse prognosis than other Lauren’s histological classification. Integrin β1 (ITGB1) was a member of integrin family which played a markedly important role in tumorigenesis and progression. However, the influence of ITGB1 in diffuse gastric cancer (DGC) remains uncertain. Here, we leveraged the transcriptomic and proteomic data to explore the association between ITGB1 expression and clinicopathologic information and biological process in DGC. Cell phenotype experiments combined with quantitative-PCR (q-PCR) and western blotting were utilized to identify the potential molecular mechanism underling ITGB1.Transcriptomics and proteomics both revealed that the higher ITGB1 expression was significantly associated with worse prognosis in DGC, but not in intestinal GC. Genomic analysis indicated that the mutation frequency of significantly mutated genes of ARID1A and COL11A1, and mutational signatures of SBS6 and SBS15 were markedly increased in the ITGB1 low expression subgroup. The enrichment analysis revealed diverse pathways related to dysregulation of ITGB1 in DGC, especially in cell adhesion, proliferation, metabolism reprogramming, and immune regulation alterations. Elevated activities of kinase-ROCK1, PKACA/PRKACA and AKT1 were observed in the ITGB1 high-expression subgroup. The ssGSEA analysis also found that ITGB1 low-expression had a higher cuproptosis score and was negatively correlated with key regulators of cuproptosis, including FDX1, DLAT, and DLST. We further observed that the upregulated expression of mitochondrial tricarboxylic acid (TCA) cycle in the ITGB1 low-expression group. Reduced expression of ITGB1 inhibited the ability of cell proliferation and motility and also potentiated the cell sensitive to copper ionophores via western blotting assay. Overall, this study revealed that ITGB1 was a protumorigenic gene and regulated tumor metabolism and cuproptosis in DGC.

Abstract
BACKGROUND To develop a CT-based radiomics nomogram for the high-precision preoperative differentiation of gastric hepatoid adenocarcinoma (GHAC) patients from gastric adenocarcinoma (GAC) patients. RESEARCH DESIGN AND METHODS 108 patients with GHAC from 6 centers and 108 GAC patients matched by age, sex and T stage undergoing pathological examination were retrospectively reviewed. Patients from 5 centers were divided into two cohorts (training and internal validation) at a 7:3 ratio, the remaining patients were external test cohort. Venous-phase CT images were retrieved for tumor segmentation and feature extraction. A radiomics model was developed by the least absolute shrinkage and selection operator method. The nomogram was developed by clinical factors and the radiomics score. RESULTS 1409 features were extracted and a radiomics model consisting of 19 features was developed, which showed a favorable performance in discriminating GHAC from GAC (AUCtraining cohort = 0.998, AUCinternal validation set = 0.942, AUCexternal test cohort = 0.731). The radiomics nomogram, including the radiomics score, AFP, and CA72_4, achieved good calibration and discrimination (AUCtraining cohort = 0.998, AUCinternal validation set = 0.954, AUCexternal test cohort = 0.909). CONCLUSIONS The noninvasive CT-based nomogram, including radiomics score, AFP, and CA72_4, showed favorable predictive efficacy for differentiating GHAC from GAC and might be useful for clinical decision-making.

Abstract
Gastric cancer (GC) is one of the most common malignancies with a poor prognosis. Immunotherapy has attracted much attention as a treatment for a wide range of cancers, including GC. However, not all patients respond to immunotherapy. New models are urgently needed to accurately predict the prognosis and the efficacy of immunotherapy in patients with GC. Long noncoding RNAs (lncRNAs) play crucial roles in the occurrence and progression of cancers. Recent studies have identified a variety of prognosis-related lncRNA signatures in multiple cancers. However, these studies have some limitations. In the present study, we developed an integrative analysis to screen risk prediction models using various feature selection methods, such as univariate and multivariate Cox regression, least absolute shrinkage and selection operator (LASSO), stepwise selection techniques, subset selection, and a combination of the aforementioned methods. We constructed a 9-lncRNA signature for predicting the prognosis of GC patients in The Cancer Genome Atlas (TCGA) cohort using a machine learning algorithm. After obtaining a risk model from the training cohort, we further validated the model for predicting the prognosis in the test cohort, the entire dataset and two external GEO datasets. Then we explored the roles of the risk model in predicting immune cell infiltration, immunotherapeutic responses and genomic mutations. The results revealed that this risk model held promise for predicting the prognostic outcomes and immunotherapeutic responses of GC patients. Our findings provide ideas for integrating multiple screening methods for risk modeling through machine learning algorithms.

Abstract
OBJECTIVE Heated and humidified high-flow nasal cannula (HFNC) therapy has been used to manage different respiratory conditions in pediatric patients. However, no review has summarized its efficacy for the management of pediatric obstructive sleep apnea (OSA). MATERIALS AND METHODS PubMed, Embase, CENTRAL, and Google Scholar were searched for all types of studies assessing the efficacy of HFNC for pediatric OSA. We compared pre-treatment and post-treatment obstructive apnea-hypopnea index (OAHI), obstructive hypopnea index (OHI), obstructive apnea index (OAI), SPO2 nadir and SPO2 mean values in a random-effect meta-analysis model. RESULTS Six studies reporting data of 67 pediatric patients treated with HFNC were included. Most of the data were from one-time titration. Meta-analysis revealed a statistically significant reduction in OAHI with HFNC therapy (MD: 15.58 95% CI: 8.30, 22.86 I2=77% p=0.001). Similarly, pooled analysis revealed that both OHI (MD: 12.35 95% CI: 0.78, 23.92 I2=98% p=0.04) and OAI (MD: 7.54 95% CI: 2.10, 12.98 I2=79% p=0.007) were significantly reduced with HFNC treatment. Also, HFNC led to statistically significant improvement in SPO2 nadir values (MD: -8.17 95% CI: -10.40, -5.94 I2=21% p<0.00001) but it did not change the mean SPO2 values before and after treatment (MD: -0.85 95% CI: -1.94, 0.25 I2=52% p=0.13). CONCLUSIONS Evidence from a limited number of heterogeneous and uncontrolled titration studies indicates that HFNC improves OAHI and minimum oxygen saturation in pediatric patients with OSA. However, further research is required on the long-term efficacy and compliance of HFNC therapy with a focus on different pediatric age groups.

Abstract
This study was designed to investigate the potential key genes of ADP-ribosylation factor-like 15 (ARL15) regulating glycolysis and lipogenesis in colon cancer. Hematoxylin-eosin (HE) staining and immunohistochemistry were used to observe the expression of ARL15 in 10 normal colon tissues and 10 colon cancer tissues. Immunofluorescence staining was used to observe the expression position of ARL15 in normal human colorectal mucosa cells (FHC) and colon cancer cells (HCT116 and SW620) with a confocal microscope. The ARL15 plasmid and small interfering RNA (siRNA) were constructed. After transfection, the expression levels of glycolysis and lipogenesis regulatory enzymes and messenger RNA (mRNA) transcription of ARL15 in over-expressed and silenced colon cancer cells were detected by Western blotting and real-time quantitative PCR (qRT-PCR). High expression of ARL15 in colon cancer tissue and low expression in normal colon tissue, and all expression are in the cytosol. The expression position of ARL15 in the FHC, HCT116, and SW620 cells was consistent and mainly distributed in the cytosol. After the pCMV-3Tag-2-ARL15 plasmid was transfected in HCT116, the protein expressions of FASN, AKT, P-AKT, P-GSK, SREBP-1 (p125) (p<0.01), and AMPK (p<0.001) were higher than those in the control group. The mRNA transcription level of FASN, GSK, AMPKa1, and SREBP-1 gene was higher than control group after the over-expression of ARL15. After the ARL15-siRNA was transfected in HCT116, the protein expression levels of PKM2, PFK, FASN, AKT, P-AKT, P-GSK, and AMPK decreased compared with the control group, (p<0.05). The mRNA transcription level of FASN, GSK, AMPKα1 gene was lower than control group after the low-expression of ARL15 (p<0.05). After adding 2 μM JIB-04, ARL15 in HCT116 showed statistical differences compared with the control group at 12 h, 24 h and 36 h (p<0.05). After adding 2 μM JIB-04, the protein expression levels of AKT, p-GSK, FASN, AMPK and SREBP-1 in HCT116 cells decreased significantly after 24 h. It was also found that the expression levels of AKT, P-GSK, FASN, AMPK and SREBP-1 genes in the dose-adding group were significantly lower than those in the control group. In summary, ARL15 may promote the occurrence of colon cancer by increasing the expression of protein kinase B/AMP-activated protein kinase (AKT/AMPK) downstream regulatory enzymes for glycogenesis and lipogenesis. JIB-04 can target ARL15 and affect its expression as well as the expressions of glucose and lipid metabolity-related proteins in AKT and AMPK signaling pathways.

Abstract
At present, it is commonly believed that tRFs and tiRNAs are formed by the specific and selective shear of tRNAs under certain pressure stimulation, rather than by random degradation of tRNA. tRFs and tiRNAs have been reported to contribute to the biological process of a variety of human cancers. However, the evidence for the mechanisms of tRFs and tiRNAs in the occurrence and development of gastric cancer (GC) is still insufficient. Here, we aimed to explore the carcinogenic roles of tRFs and tiRNAs in GC with RNA-sequencing technique, and found a novel 3'tRNA-derived fragment tRF-Val was significantly upregulated in GC tissues and cell lines. tRF-Val expression was positively correlated with tumor size and the depth of tumor invasion in GC tissues. Functionally, tRF-Val promoted proliferation and invasion, and inhibited apoptosis in GC cells. Mechanistically, tRF-Val directly bound to the chaperone molecule EEF1A1, mediated its transport into the nucleus and promoted its interaction with MDM2 (a specific p53 E3 ubiquitin ligase), thus inhibiting the downstream molecular pathway of p53 and promoting GC progression. These findings provided a new potential therapeutic target for GC and a new explanation for the occurrence of GC.

Abstract
Recent studies highlighted the clinicopathologic importance of tumor microenvironment (TME) in delineating molecular attributes and therapeutic potentials. However, the overall TME cell-infiltration landscape in non-squamous NSCLC have not been comprehensively recognized. In this study, we employed consensus non-negative matrix factorization (NMF) molecular subtyping to determine the TME cell infiltration patterns and identified three TME clusters (TME-C1, -C2, -C3) characterized by distinct clinicopathologic features, infiltrating cells, and biological processes. Proteomics analyses revealed that cGAS-STING immune signaling mediated protein and phosphorylation level were significantly upregulated in inflamed-related TME-C2 clusters. The TMEsig-score extracted from the TME-related signature divided NSCLC patients into high- and low-score subgroups, where a high score was associated with favorable prognosis and immune infiltration. Genomic landscape revealed that patients with low TMEsig-score harbored greater somatic copy number alternations and higher mutation frequency of driver genes involving STK11, KEAP1 and SMARCA4 et al. Drug sensitivity analyses suggested that tumors with high TMEsig-score were responsible for favorable clinical response to immune check-point inhibitors (ICI) treatment. In summary, this study highlights that comprehensive recognizing of the TME cell infiltration landscape will contribute to enhance our understanding of TME immune regulation and promote effectiveness of precision biotherapy strategies.

Abstract
BACKGROUND A novel multidimensional inflammatory and nutritional assessment system named the Naples prognostic score could serve as an independent prognostic indicator. However, its significance in patients with high- and intermediate-risk gastrointestinal stromal tumours remains unclear. METHODS We performed this retrospective cohort study based on a prospectively collected database of gastrointestinal stromal tumours (GISTs) between March 2010 and December 2019. The Kaplan-Meier method and log-rank test were used for survival analyses. Least absolute shrinkage and selection operator (LASSO) and Cox proportional hazards regression analysis was used for univariate and multivariate analyses. Time-dependent receiver operating characteristic curves were generated to evaluate the discriminatory ability of the prognostic scoring systems. Differences in the areas under the curve were further compared. RESULTS A total of 405 patients with regular follow-up were included and analysed in this study. Significant differences in progression-free survival and overall survival were observed between the groups (P < 0.001). Multivariate analysis demonstrated that the NPS was a significant predictor of poor progression-free survival (1 vs 0, HR = 4.622, P = 0.001; 2 vs 0, HR = 12.770, P < 0.001) and overall survival (2 vs 0, HR = 5.535, P = 0.002). Furthermore, time-dependent AUC analyses showed that the NPS was more accurate than other haematologic prognostic systems. CONCLUSIONS The present study demonstrates that the NPS could independently predict disease progression and survival among patients with high- and intermediate-risk GISTs. The NPS might be regarded and applied as one of the most convenient and effective preoperative risk stratification tools in the future, which should be validated by large-scale multicentre prospective cohort studies.

Abstract
Integrative expression Quantitative Trait Loci (eQTL) analysis found that rs8180040 was significantly associated with Coiled-coil domain containing 12 (CCDC12) in colon adenocarcinoma (COAD) patients. Immunohistochemical staining and western blotting confirmed CCDC12 was highly expressed in COAD tissues, which was consistent with RNA-Seq data from the TCGA database. Knockdown of CCDC12 could significantly reduce proliferation, migration, invasion, and tumorigenicity of colon cancer cells, while exogenous overexpression of CCDC12 had the opposite effect. Four plex Isobaric Tags for Relative and Absolute Quantitation assays were performed to determine its function and potential regulatory mechanism and demonstrated that overexpression of CCDC12 would change proteins on the adherens junction pathway. Overexpressed Snail and knocked down CCDC12 subsequently in SW480 cells, and we found that overexpression of Snail did not significantly change CCDC12 levels in SW480 cells, while knockdown of CCDC12 reduced that of Snail. CCDC12 plays a significant role in tumorigenesis, development, and invasion of COAD and may affect the epithelial to mesenchymal transformation process of colon cancer cells by regulating the Snail pathway.

Abstract
RNA N6-methyladenosine (m6A) modification in tumorigenesis and progression has been highlighted and discovered in recent years. However, the molecular and clinical implications of m6A modification in melanoma tumor microenvironment (TME) and immune infiltration remain largely unknown. Here, we utilized consensus molecular clustering with nonnegative matrix factorization based on the melanoma transcriptomic profiles of 23 m6A regulators to determine the m6A modification clusters and m6A-related gene signature. Three distinct m6A modification patterns (m6A-C1, C2, and C3), which are characterized by specific m6A regulator expression, survival outcomes, and biological pathways, were identified in more than 1,000 melanoma samples. The immune profile analyses showed that these three m6A modification subtypes were highly consistent with the three known immune phenotypes: immune-desert (C1), immune-excluded (C2), and immune-inflamed (C3). Tumor digital cytometry (CIBERSORT, ssGSEA) algorithm revealed an upregulated infiltration of CD8+ T cell and NK cell in m6A-C3 subtype. An m6A scoring scheme calculated by principal component of m6A signatures stratified melanoma patients into high- and low-m6sig score subgroups; a high score was significantly associated with prolonged survival and enhanced immune infiltration. Furthermore, fewer somatic copy number alternations (SCNA) and PD-L1 expression were found in patients with high m6Sig score. In addition, patients with high m6Sig score demonstrated marked immune responses and durable clinical benefits in two independent immunotherapy cohorts. Overall, this study indicated that m6A modification is involved in melanoma tumor microenvironment immune regulation and contributes to formation of tumor immunogenicity. Comprehensive evaluation of the m6A modification pattern of individual tumors will provide more insights into molecular mechanisms of TME characterization and promote more effective personalized biotherapy strategies.

Abstract
Sulforaphane and sulforaphene are isothiocyanate compounds derived from cruciferous vegetables that have demonstrated antiproliferative properties against colon cancer. However, the underlying mechanism of action of these two compounds has yet to be elucidated. The aim of the present study was to examine the effects of sulforaphane and sulforaphene on colon cancer using next-generation sequencing (NGS). The SW480 colon cancer cell line was cultured with 25 µmol/l sulforaphane or sulforaphene. Total RNA was extracted from the cells following 48 h of incubation with these compounds, and NGS was performed. Pearson's correlation and principal component analyses were performed on the NGS data in order to determine sample homogeneity followed by hierarchical clustering, chromosomal location, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. A total of 873 probes in the sulforaphene group were differentially expressed compared with the control group. Similarly, 959 probes in the sulforaphane group were differentially expressed compared with the control group. The differentially expressed genes were dispersed on the chromosomes, across 22 pairs of autosomes, as well as the X and Y chromosomes. GO and KEGG analyses demonstrated that both drugs affected the ‘p53 signaling pathway’, ‘MAPK signaling pathway’, ‘FOXO signaling pathway’ and ‘estrogen signaling pathway’, while ‘Wnt signaling pathway’ was enriched in the sulforaphane group, and ‘ubiquitin mediated proteolysis’ and ‘estrogen signaling pathway’ in the sulforaphene group. Thus, sulforaphane and sulforaphene exhibited similar biological activities on colon cancer cells. Sulforaphane and sulforaphene may be associated with Wnt and estrogen signaling, respectively.

Abstract
Abstract
Study question
what is the source, prevalence, and influence of microbial contamination on in vitro fertilization (IVF) and embryo transfer (ET) cycles?
Summary answer
Microbial contamination mainly occurs on Day 2, most caused by Escherichia coli carried with semen. ICSI could prevent contamination effectively and get good clinical outcomes.
What is known already
Microbial contamination occurs in IVF-ET system occasionally, which is hard to stop happening. The IVF culture system and laboratory environment, the patients’ follicular fluid and semen are not absolutely sterile, while the antibiotics in culture medium isn’t effective for all microbe types, and the artificial operations may bring in microbes. Generally, microbial contamination leads to degradation of embryos, reduction the number of embryos available, and infection of female reproductive tract, which would increase the cost of patients’ time, money, and bring psychological damages. A better understanding of embryo contamination in IVF culture system is of added value.
Study design, size, duration
A total of 29583 IVF-ET cycles were enrolled in this prospective observational study, from January 2010 to December 2020, included 70 microbial contamination cycles discovered in Day1-Day3 (D1-D3) of in vitro culture. Follicular fluid and semen saved on oocyte retrieval day, and culture medium contaminated were examined and identified for microorganisms at each contamination cycle.
Participants/materials, setting, methods
Compared the contamination rate of different insemination methods (IVF/ICSI/IVF+ICSI), different in vitro culture days (D1-D3), and different samples examination (follicular fluid, semen, culture medium) respectively, identified the source of microorganism types, compared the IVF culture outcomes and clinical outcomes between total contamination group (TC group, 42 cases) and partial contamination group (PC group, 28 cases).
Main results and the role of chance
A total of 70 microbial contamination cases occurred in 29583 oocyte retrieving cycles (0.24%), and it was observed only in IVF embryos but never in ICSI (Intracytoplasmic sperm injection) embryos. 38 contamination cases occurred on D2 with a highest ratio (54.3%) compared to D1 (32.9%) and D3(12.9%); Compared with follicular fluid, semen was the main cause inducing contamination from D1 to D3, and Escherichia coli in semen and culture medium, Enterococcus faecalis in follicular fluid proved to be the most common sources. Compared with TC group, the PC group showed a lower rate of No-available embryos (21.4% vs 81.0%) and a higher rate of blastocyst formation (41.2% vs 28.6%), In addition, the clinical pregnancy rate of PC group was higher than that of TC group in both fresh and frozen-thawed embryo transfer cycles (31.3% vs 16.7%, 38.5% vs 0.0%).
Limitations, reasons for caution
Further study is still necessary to better understand the sources that induce microbial contamination embryos, and more efficient methods are required to remove the microbes on these contaminated embryos so as better develop and manage a sterile micro-environment for successful embryo growth.
Wider implications of the findings: The differential embryonic microbe types associated to different IVF culture and clinical outcomes in patients undergoing IVF-ET might have profound implications for understanding the microbial sources and making a better management of IVF culture system.

Abstract
Background:Iguratimod (IGU) has demonstrated efficacy and safety for active rheumatoid arthritis (RA) patients in double-blind clinical trials in China and Japan as a new disease-modifying anti-rheumatic drug (DMARD). There are no studies evaluating the radiographic progression of structural joint damage of IGU for the treatment of RA using the mTSS as the primary endpoint.Objectives:Our study was to evaluate the efficacy and safety of IGU monotherapy and IGU combined methotrexate (MTX) compared with MTX monotherapy, including the inhibitory effects of joint destruction.Methods:This randomized, double-blind, parallel-controlled, multicenter study in patients with active RA who have not previously used MTX and biological DMARDs (bDMARDs) (ClinicalTrials.gov Identifier NCT01548001) was carried out in China. Patients were randomized 1:1:1 to receive IGU 25 mg twice a day (bid), MTX 10mg once a week(qw) for the first 4 weeks and 15 mg once a week(qw) for week 5 to 52, or IGU combined MTX (IGU+MTX) for 52 weeks. The primary endpoints were to assess and compare American College of Rheumatology 20% (ACR20) response and the change of modified total Sharp scoring (mTSS) score over 52 weeks (Intention-to-treat, ITT analysis). The non-inferiority test was used to analyze the difference of ACR20 response at 52 weeks between the IGU monotherapy and the MTX monotherapy arms, and the non-inferiority limit value was 10%. The difference test was used for the comparison between the IGU+MTX and MTX monotherapy arms. Two-way ANOVA was used to analyze the difference of the changes of mTSS score of each arm compared with baseline value (0 week).Results:A total of 895 patients were randomized to IGU 25mg bid (n =297), MTX 10-15mg qw(n=293), and IGU+MTX (n=305).

Abstract
Gastric cancer (GC) is a common tumour that affects humans worldwide, is highly malignant and has a poor prognosis. Small extracellular vesicles (sEVs), especially exosomes, are nanoscale vesicles released by various cells that deliver bioactive molecules to recipient cells, affecting their biological characteristics, changing the tumour microenvironment and producing long-distance effects. In recent years, many studies have clarified the mechanisms by which sEVs function with regard to the initiation, progression, angiogenesis, metastasis and chemoresistance of GC. These molecules can function as mediators of cell-cell communication in the tumour microenvironment and might affect the efficacy of immunotherapy. Due to their unique physiochemical characteristics, sEVs show potential as effective antitumour vaccines as well as drug carriers. In this review, we summarize the roles of sEVs in GC and highlight the clinical application prospects in the future.

Abstract
BACKGROUND Computed tomography (CT) has become an important technique for assessing skeletal muscle mass. Low skeletal muscle mass (LSMM) is considered an unfavorable factor for postoperative complications in patients with gastric cancer (GC). METHODS Patients who underwent laparoscopic gastrectomy for GC were included. Skeletal muscle mass at the third lumbar vertebra (L3) level was measured by preoperatively using CT. The patients were divided into an LSMM group and a non-LSMM group and the intergroup differences were analyzed. Furthermore, we divided the LSMM group into mild and severe LSMM subgroups. The study also analyzed the influence of obesity-related LSMM on postoperative complications. RESULTS A total of 409 patients were enrolled; of them, 265 had LSMM and 41 had severe LSMM. LSMM was associated with age, body mass index, and Nutritional Risk Screening 2002 score. In the multivariate analysis, LSMM was not related to postoperative complications. Further analysis revealed that severe LSMM was a risk factor for postoperative complications. The study also found that the risk of postoperative complications was significantly increased in patients with obesity-related LSMM. CONCLUSIONS LSMM was not significantly correlated with postoperative complications. Severe LSMM and obesity-related LSMM are unfavorable factors for postoperative complications with GC after gastrectomy.

Abstract
Recent studies have highlighted the biological significance of RNA N6-methyladenosine (m6A) modification in tumorigenicity and progression. However, it remains unclear whether m6A modifications also have potential roles in immune regulation and tumor microenvironment (TME) formation. Methods: In this study, we curated 23 m6A regulators and performed consensus molecular subtyping with NMF algorithm to determine m6A modification patterns and the m6A-related gene signature in colon cancer (CC). The ssGSEA and CIBERSORT algorithms were employed to quantify the relative infiltration levels of various immune cell subsets. An PCA algorithm based m6Sig scoring scheme was used to evaluate the m6A modification patterns of individual tumors with an immune response. Results: Three distinct m6A modification patterns were identified among 1307 CC samples, which were also associated with different clinical outcomes and biological pathways. The TME characterization revealed that the identified m6A patterns were highly consistent with three known immune profiles: immune-inflamed, immune-excluded, and immune-desert, respectively. Based on the m6Sig score, which was extracted from the m6A-related signature genes, CC patients can be divided into high and low score subgroups. Patients with lower m6Sig score was characterized by prolonged survival time and enhanced immune infiltration. Further analysis indicated that lower m6Sig score also correlated with greater tumor mutation loads, PD-L1 expression, and higher mutation rates in SMGs (e.g., PIK3CA and SMAD4). In addition, patients with lower m6Sig scores showed a better immune responses and durable clinical benefits in three independent immunotherapy cohorts. Conclusions: This study highlights that m6A modification is significantly associated with TME diversity and complexity. Quantitatively evaluating the m6A modification patterns of individual tumors will strengthen our understanding of TME characteristics and promote more effective immunotherapy strategies.

Abstract
FibroTouch (FT) has been used widely in clinic. Studies of the FT diagnostic efficiency and influencing factors of liver stiffness measurement (LSM) of liver fibrosis in autoimmune liver diseases (AILD) have shown that FT has a good diagnostic efficiency and accuracy, especially in AIH. However, for patients with primary biliary cholangitis and overlap syndrome of autoimmune hepatitis, FT results should be vigilant. In addition, the diagnostic efficiency of FT. Notably, when using FT to diagnose AILD, the value of elastic stiffness depends on five influencing factors, such as, age, total bile acid, international standardized ratio, FIB-4 index, and prothrombin time.

Abstract
BACKGROUND With the increasing prevalence of Siewert type Ⅱ adenocarcinoma of the esophagogastric junction (EGJ), the optimal surgical treatment is not universally agreed. This meta-analysis compares the safety and efficacy between the transhiahtal (TH) approach and the transthoracic (TT) approach. METHODS A systematic and electronic search of several databases was performed up to June 2020. The Newcastle-Ottawa scale was used to evaluate article quality and funnel plots were created to identify potential publication bias. The random-effects model was used when significant heterogeneity was identified. RESULTS In total, nine retrospective studies and two randomized controlled trials (RCTs) involving 2331 patients were included. Decreased intraoperative blood loss, shorter hospital stay, lower incidence of pulmonary complications, and longer 3-year overall survival were observed in the TH group. There were no significant differences concerning duration of surgery, R0 resection rate, number of dissected lymph nodes, perioperative mortality and morbidity rate, abdominal complication rate, or anastomotic leak rate. With regard to 5-year overall survival, a potential benefit may be achieved with the TH approach, which requires further confirmation. CONCLUSION In terms of surgery-related and long-term outcomes, the TH approach may be more appropriate for Siewert type Ⅱ adenocarcinoma of EGJ, especially for esophagus invasion ≤4 cm.

Abstract
Genome-wide association studies of colorectal cancer (CRC) have identified two risk SNPs. The characterization of these risk regions in diverse racial groups with different linkage disequilibrium structure would aid in localizing the causal variants. Herein, fine mapping of the established CRC loci was carried out in 1,508 cases and 1,482 controls obtained from the Han Chinese population. One distinct association signal was identified at these loci, where fine mapping implicated rs1010208 as a functional locus. Next, the candidate target genes of functional SNP rs1010208 were analyzed using data from TCGA databases by expression quantitative trait loci analysis method; the data from Peking University People's Hospital were utilized for verification. The dual-luciferase reporter system analysis confirmed that rs1010208 is a regulatory region that can be mutated to decrease the expression of HINT1, resulting in proliferation and invasiveness of CRC.

Abstract
Immune checkpoint inhibitor (ICI) therapy has achieved remarkable clinical benefit in melanoma and non-small cell lung cancer (NSCLC). Tumor mutational signatures are the fingerprints of endogenous and exogenous factors that have acted throughout tumorigenesis and heterogeneity; however, their association with immune response in ICI-treated samples remains unclear. Here, we leveraged whole-exome sequencing (WES)-based mutational profiles combined with clinicopathologic characteristics from melanoma and NSCLC datasets to examine whether tumor genomic features contribute to clinical benefit of ICI treatment. Mutational data acquired from targeted next-generation sequencing (NGS) assays (MSK-IMPACT panels) were also employed for further corroboration. A mutational signature (known as age-related clock-like processing) characterized by enrichment of C>T mutations at NpCpG trinucleotides were identified to be associated with a worse prognosis and lower tumor mutation load (TML) in both WES and targeted NGS immunotherapy cohorts. We also analyzed gene transcriptomic profiles and identified immune regulation-related gene pathways that were significantly altered in samples with different clock-like signature grouping. Leucocyte subset analysis further revealed that clock-like signature was associated with the reduction of cytotoxic cell infiltration and elevation of regulatory T cells. Overall, our work re-annotated that the age-related clock-like signature was associated with worse prognosis and lower immune activity, offering opportunities to stratify patients into optimal immunotherapy plans based on genomic subtyping.

Abstract
Background NF1(Neurofibromatosis type 1) is an autosomal dominant genetic disorder. Patients with NF1 have an increased risk of developing benign or malignant tumours, such as gastrointestinal stromal tumours (GISTs). However, the coexistence of NF1, GIST and colon cancer is very rare, and few cases have been reported in the literature. Case presentation We admitted a case of a 64-year-old man with type 1 neurofibromatosis, GISTs, and ascending colon cancer. This case was characterized by café-au-lait macules, discrete cutaneous neurofibromas, nodular neurofibromas, multiple jejunal tumours, and ascending colon cancer. Laparoscopic exploration revealed ascending colon cancer and multiple jejunal tumours. Laparoscopic right hemicolectomy and local excision of the jejunal tumours were performed successfully. The pathological results confirmed moderate differentiated adenocarcinoma of the ascending colon with multiple jejunal GISTs (low risk, very low risk). Moreover, the immunohistochemistry results of multiple jejunal GISTs suggest that NF1 is positive. Whole-exome sequencing (WES) of colon cancer revealed mutations in more than 20 genes, including KRAS, PIK3CA, APC, SMAD4, etc. The results of whole-exome sequencing (WES) of jejunal GISTs revealed an NF1 mutation and no KIT or PDGFR gene mutation. Conclusion We report a rare case of simultaneous NF1, GIST and colon adenocarcinoma. For patients with NF1, benign and/or malignant tumours are often combined. Therefore, these patients should undergo regular physical examinations so that early detection and early treatment can be achieved.

Abstract
Objective: To investigate the protective effect of carbon monoxide releasing molecule 2 (CORM-2) on post-resuscitation myocardial dysfunction in rats. Methods: Forty male SD rats which were healthy were randomly divided into 5 groups: sham operated group(sham group), cardiopulmonary resuscitation(PCR) group, DMSO group, inactivated CORM-2(iCORM-2) group and CORM-2 group (n=8 each). Established the model of post-cardiac arrest myocardial dysfunction by intravenous potassium chloride (4 ℃) injection combined with asphyxiation for 4 minutes and then followed by artificial chest compression for 3 minutes. Sham group: rats were instrumented with catheter without inducing cardiac arrest and resuscitation, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before catheterization. CPR group: rats were instrumented with catheters and underwent CPR, and intraperitoneal injection of 0.9% normal saline (4 ml/kg) was performed 12 hours before surgery.CORM-2 group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared CORM-2 solution (4 mg/kg) at 12 hours before surgery. DMSO group: rats were instrumented with catheters and underwent CPR, intraperitoneally injected the prepared DMSO solution (4 ml/kg) at 12 hours before surgery. iCORM-2 group: rats were instrumented with catheters and underwent CPR, iCORM-2 solution (4 mg/kg) was intraperitoneally injected at 12 hours before surgery. Hemodynamic data (MAP, +dp/dtmax, -dp/dt) were continuously monitored and recorded for 4 hours after resuscitation (or catheterization) in each group. Myocardial tissue specimen and blood samples were taken after resuscitation (or catheterization). The myocardial ultrastructure was observed by transmission electron microscope. Lactate dehydrogenase (LDH) activity was measured by lactate-pyruvate method. Serum creatine kinase isoenzyme (CK-MB) concentration was measured by ELISA. Western blot was used to detect the levels of Caspase-3, Caspase-9 and Cyt-C protein in myocardial tissue. Results: MAP, +dp/dtmax and -dp/dt at 0.5, 1, 2, 3 and 4 hours post resuscitation were significantly lower than those immediately after catheterization in CRP, DMSO, iCORM-2 groups (all P<0.05). MAP at 0.5, 1, 2, 3, and 4 hours post resuscitation were significantly lower in CRP, DMSO and iCORM-2 groups than those at respective time points in sham group (all P<0.05), while MAP was similar between CORM-2 group and Sham group at these time points (all P>0.05). +dp/dtmax and -dp/dt values at 0.5, 1, 2, 3, and 4 hours post resuscitation were lower than those at respective time points in sham group and significance was found at 0.5, 1 and 2 hours post resuscitation (both P<0.05), while +dp/dtmax and -dp/dt values were similar between CORM-2 group and sham group at various time points (all P>0.05). Myocardial ultrastructure, especially mitochondrial structural integrity was better preserved in the CORM-2 group than those in the other resuscitation groups at 4 hours after resuscitation. Serum LDH activity and CK-MB concentration were significantly elevated at 4 hours after resuscitation in the CPR group, DMSO group and iCORM-2 group than those in sham group (all P<0.01); CK-MB concentration was also higher in CORM-2 group than that in sham group,and LDH level was similar between CORM-2 group and sham group (P>0.05). Serum LDH activity and CK-MB concentrations were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.01). The myocardial expressions of Caspase-3, Caspase-9 and Cyt-C at 4 hours after resuscitation were significantly higher in the CPR group, DMSO group and iCORM-2 group than those in sham group; the myocardial expressions of Caspase-3 and Caspase-9 were significantly higher in CORM-2 group than those in sham group (both P<0.05), while Cyt-C expression was similar between CORM-2 group and sham group. The expressions of the above 3 proteins were significantly lower in the CORM-2 group than those in the other resuscitation groups (all P<0.05). Conclusions: CORM-2 can effectively alleviate post-resuscitation myocardial injury in rats with cardiopulmonary resuscitation and improve cardiac function. Protecting myocardial mitochondria and inhibiting mitochondrial apoptosis pathway may serve as the protective mechanisms in this model.

Abstract
Abstract
To analyze the correlation of the level of serum heat shock protein 90α (HSP-90α) in healthy and breast cancer patients, studying the evaluation of neoadjuvant efficacy and Clinical value of relapse monitoring.
A total of 102 healthy women were selected, 51 cases of breast benign tumor ,423 cases of female breast cancer all diagnosed by pathology,other system malignancies 62 cases. ALL the serum samples HSP-90αwas detected by double-antibody ELISA. The CEA, CA125,CA15-3 were detected by Roche Cobas ECL analyzer. The ROC curve was used to analyze the effectiveness of serum HSP-90α in the early diagnosis of breast cancer. The dynamic changes of HSP-90αlevel before and after treatment were analyzed by Wilcoxon's rank test. Moreover, we also combine the HSP-90αwith CEA,CA125,CA15-3 to evaluate the clinical value of monitoring the recurrence of breast cancer.
The levels of serum HSP-90α (123.49 ± 105.1ng / ml) in breast cancer patients wes significantly higher than that in healthy controls (40.33 ± 14.18ng / ml), benign breast disease (80.15 ± 103.09ng / ml) and carcinoma in situ (34.7 ± (114.31 ± 146.91ng / ml),the difference was statistically significant (P <0.001). .According to the ROC curve analysis of patients and healthy subjects, the cut-offvalue was set as HSP-90=59.7ng / ml, AUC=0.834, the sensitivity and specificity to diagnosis of breast cancer was 90.3% and 78.6% respectively ,the negative predictive value was 93.88%.The levels of serum HSP-90α was significantly decreased (P <0.05) after tumor resection and the patients who obtain PR from the neoadjuvant chemotherapy. When HSP-90=43.22ng / ml was set as the cut-off value for diagnosing the recurrence of breast cancer, AUC=0.877,the sensitivity and specificity were 95.7% and 74.5% respectively, and the negative predictive value was 96.2%. At the same time, we find that combined HSP-90α with CEA, CA125, CA15-3 can improve the accuracy of recurrence prediction.
Serum HSP-90α has a good clinical diagnostic value in breast cancer and can be used as a recurrence monitoring tool for post-adjuvant treatment patients.

Abstract
BACKGROUND In the West, the safety and efficacy of the Lotus valve have been demonstrated; however, data in the Chinese population are still lacking. Few studies have compared the clinical outcomes of transcatheter aortic valve replacement (TAVR) with the Lotus valve in patients with bicuspid or tricuspid aortic valve stenosis. Our aim was to assess TAVR outcomes with the Lotus aortic valve in a Chinese patient cohort. METHODS In total, 23 symptomatic, high-surgical risk patients with severe aortic valve stenosis were enrolled. Among them, nine patients (39%) had bicuspid aortic valves, and three patients had a large annulus dimension. The Lotus valve was successfully implanted in all patients. To facilitate accurate positioning, partial re-sheathing was attempted in ten patients (43.5%), while one patient had a full retrieval. One-year clinical follow-up was completed in all patients. RESULTS There were no deaths, strokes, or major adverse cardiac and cerebrovascular events in 22 of the 23 patients at 30 days; the all-cause mortality rate at 1 year was 4.4% (1 of 23 patients). The mean aortic valve gradient decreased from 51.5 ± 8.8 mm Hg at baseline to 13.4 ± 4.9 mm Hg (p < 0.001) and the valve area increased from 0.6 ± 0.2 cm2 to 1.5 ± 0.4 cm2 (p < 0.001) at 30 days. Paravalvular leakage was absent or mild (22%), and no patient had severe paravalvular leakage. Six patients (26.1%) required a postprocedural pacemaker. There was no difference regarding the procedural and the 1‑year outcomes between patients with bicuspid and tricuspid aortic valve stenosis. CONCLUSION Our single-center experience demonstrated that the Lotus valve is feasible and effective for Chinese patients with aortic valve stenosis, including atypical cases with bicuspid aortic valves or large aortic annulus size.

Abstract
Magnetic particle imaging is an emerging tomographic technique with the potential for simultaneous high-resolution, high-sensitivity, and real-time imaging. Magnetic particle imaging is based on the unique behavior of superparamagnetic iron oxide nanoparticles modeled by the Langevin theory, with the ability to track and quantify nanoparticle concentrations without tissue background noise. It is a promising new imaging technique for multiple applications, including vascular and perfusion imaging, oncology imaging, cell tracking, inflammation imaging, and trauma imaging. In particular, many neuroimaging applications may be enabled and enhanced with magnetic particle imaging. In this review, we will provide an overview of magnetic particle imaging principles and implementation, current applications, promising neuroimaging applications, and practical considerations.

Abstract
Objectives The aim of this study is to investigate the sex-specific aortic root anatomy in patients with bicuspid aortic valve (BAV). Patients and methods This retrospective study includes 73 consecutive patients with BAV who underwent CT evaluation before transcatheter aortic valve replacement (TAVR) between July 2013 and April 2017 in the Second Affiliated Hospital of Zhejiang University. Result The size of the annulus, diameter and height of the sinotubular junction (STJ), height of the coronary artery ostia, and dimension of the aorta were measured. Women had significantly smaller annulus parameters (mean diameter: 23.4 ± 1.8 vs. 26.1 ± 2.1 mm; area: 425.3 ± 59.4 vs. 527.4 ± 84.6 mm2; perimeter: 74.3 ± 5.2 vs. 83.2 ± 6.4 mm), and STJ diameter (29.7 ± 3.1 vs. 32.6 ± 4.5 mm) than men (p < 0.01 for all), even after adjustment for their smaller body surface area (BSA). Dimension of aorta and height of right coronary artery were also significantly smaller in women, although not when indexing for the BSA. The left ventricular ejection fraction of women is significantly higher than that of men before discharge (60.2 ± 9.7% vs. 53.7 ± 13.6%, p = 0.01). There were no differences between women and men in the all-cause 30-day and 1‑year mortality. Conclusion Women with BAV had smaller annulus and STJ diameter after indexing for BSA, reflecting a sex-specific difference. There were no differences in 30-day and 1‑year mortality between the two groups.

Abstract
Objective: To investigate the influential factors of efficacy of the first (131)I ablation therapy for thyroid remnant in papillary thyroid microcarcinoma (PTMC) patients after thyroidectomy. Methods: Eighty-nine PTMC patients who underwent twice (131)I ablation therapy and (131)I whole body follow-up scan ((131)I-WBS) within 5 to 8 months in our department from September 2007 to October 2016 were identified and enrolled in present study. Patients were divided into complete-ablation group and uncomplete-ablation group according to whether or not radioactivity was detected at the thyroid bed in (131)I-WBS. The χ(2) test and multi-variance Binary logistic regression were performed for the factors which might affect the therapeutic efficacy. Results: The first (131)I ablation therapy was successful in 41 of 89 patients (46.07%). Residual thyroid weight was found to be associated with therapeutic efficacy (P<0.05), while gender, age, surgical method, lesions'maximum diameter, with or without LN metastasis, with or without distant metastasis, time of operation from first (131)I treatment, lesions'number, thyroid stimulating hormone (TSH), thyroglobulin (Tg), the consistency of (131)I-WBS and (99)Tc(m)-pertechnatate, TNM stage, ATA risk, Tg/TSH ratio were not significant associated with therapeutic efficacy. Binary logistic regression analysis was performed in these respects and it indicated that residual thyroid weight and ATA risk were not statistically significant independent variable (P>0.05). Conclusions: Residual thyroid weight might affect efficacy of the first (131)I ablation therapy on thyroid remnant in PTMC patients after thyroidectomy, but it is not an independent factor. Multiple interrelated factors should be considered when predicting the efficacy of the first (131)I ablation therapy.

Abstract
We have investigated the relationship between plasma Na-K ATPase inhibitor activity (EDLS) and intracellular ions in 37 uremic hemodialysed hypertensive patients, and in 20 normotensive non uremic controls (NC). As compared with the NC population, significantly enhanced values for erythrocyte (RBC) Na, Ca, platelet cytosolic Ca and EDLS were observed in all the uremic patients tested just before a dialysis session, as well as a decrease in RBC Ca ATPase and in the platelet pH. In uremia, significant correlations have been noted between RBC Na and platelet Ca (r = 0.6) or systolic BP (r = 0.45); between platelet Ca and systolic blood pressure (r = 0.8) or diastolic BP (r = 0.5) and between EDLS and RBC Na, Ca or platelet Ca (r = 0.5). Anti-hypertensive treatment has no influence on these parameters. During dialysis, a significant decrease has been noted in RBC Na, Ca, platelet Ca, SBP (only in untreated patients) and EDLS and an increase in RBC Ca ATPase and platelet pH. These modifications are significantly correlated with the weight change.

Abstract
Objective: To evaluate the feasibility, safety, and preliminary efficacy of percutaneous transcystic papilla balloon dilation for the common bile duct stones. Methods: A total of 11 patients with the common bile duct stones without dilatation of the intrahepatic bile ducts treated with percutaneous transcystic papilla balloon dilation in multiple center from April 2013 to May 2015 were analyzed retrospectively.In these 11 patients, there were 3 males and 8 females.And the average age was 68(52-91) years old.All patients had no obviously dilated intrahepatic bile duct, 6 patients were not suitable for endoscopic treatment or surgery, 4 patients refused endoscopic or surgical treatment and 1 patient had a history of failed endoscopic treatment.The white blood cell count, CA19-9, total bilirubin, direct bilirubin, AST, ALT and serum amylase level were recorded before the procedure, 1 week, and 1 month later.Early complications, such as cholangitis, pancreatitis, hemorrhage, and perforation were evaluated. Results: Technical success was achieved in all the 11 cases.The level of CA19-9, total bilirubin and direct bilirubin decreased significantly 1 week and 1 month after the procedure.One patient suffered from biliary tract infection.No severe complications, such as perforation of biliary or gastrointestinal tract, occurred during the follow up.Common bile duct stone recurred in 1 patient 2 years after the procedure. Conclusions: For cases who are not suitable for endoscopic treatment, surgery, or percutaneous transhepatic approach to treat the common bile duct stones, percutaneous transcystic papilla dilation is technically feasible and safe, and seems to be an appropriate alternative strategy.

Abstract
OBJECTIVE To determine the prevalence of latent tuberculosis infection (LTBI) in college students. PATIENTS AND METHODS Four hundred and twenty newly admitted college students were enrolled. The Enzyme-Linked ImmunoSpot assay (ELISPOT) was used. Overall, 171 students with ELISPOT assay+/TST+ were monitored for three years to detect active TB disease. RESULTS The overall positive rate of ELISPOT assay was 40.7% among TST+ students. The ELISPOT positive rates were 36.9%, 45.4%, and 64.3% in groups of TST induration of 10-14mm, 15-20mm, and ≥20mm, respectively, with a significant difference (χ(2)=10.136, P<0.01) but no significant difference between BCG scar and no scar (41.2% vs. 38.8%; P>0.05). None of the 171 untreated students contracted active TB within the three-year monitoring period. CONCLUSION The LTBI rate might be overestimated by TST compared with interferon-γ release assays. On the basis of a close monitoring, few students developed active TB despite a positive result to the TST and ELISPOT assay.

Abstract
Abstract
Background: SPARC (secreted protein acidic and rich in cystein) is a secreted glycoprotein that interacts with extracellular matrix protein and acts as a regulator of critical cellular functions such as proliferation and cell migration. An increasing number of studies have shown altered expression of SPARC in several malignancies. However, the role of this potential biomarker in breast cancer development and progression is controversial. Triple-negative breast cancer (TNBC) is known for its poor prognosis and high recurrence probability. There is a need for prognostic biomarkers to guide treatment decisions for this subtype.
Objective: To explore the association between SPARC and the prognosis of triple-negative breast cancer.
Methods: In this study, a total of 211 samples of triple-negative breast lesions from 2004 to 2008 were collected in Cancer Hospital, Chinese Academy of Medical Sciences. SPARC expression was evaluated by immunohistochemistry using an immunoreactive score (IRS) from patients with up to 10 years clinical follow-up data. The current study set out to examine both the expression of SPARC in primary tumor tissue and to demonstrate if a link existed between the levels of SPARC and the clinical outcome. Cox proportional hazards model was used to estimate HRs and 95%CI, stratified on tumor grade, TNM stage, lymph node status and vascular invasion.
Results: High SPARC expression (IRS≥3) was observed in 52.1% of all primary tumors. Patients expressing low levels of SPARC had better disease-free survival (DFS) (HR=0.632, 95%CI:0.405-0.987, P = 0.044) as well as overall survival(OS)(HR=0.576, 95%CI:0.351-0.946, P = 0.029) compared to those with high SPARC expression levels.Furthermore, the presence of high SPARC expression was an independent prognostic factor for both DFS (HR=1.67, 95%CI:1.04-2.69, P=0.034) and OS(HR=1.77, 95%CI:1.04-3.01, P=0.037) of triple-negative breast cancer patients, stratified on tumor grade, TNM stage, lymph node metastasis and vascular invasion, with adjustment for age, hormonal status, tumor size, adjuvant radiotherapy and adjuvant chemotherapy.
Conclusion: Our results suggest that the presence of higher SPARC expression could be an indicator of high aggressiveness and may be a strong prognostic factor for triple-negative breast cancer.
