Abstract
Cholesterol is crucial for cell survival and growth, and dysregulation of cholesterol homeostasis has been linked to the development of cancer. The tumor microenvironment (TME) facilitates tumor cell survival and growth, and crosstalk between cholesterol metabolism and the TME contributes to tumorigenesis and tumor progression. Targeting cholesterol metabolism has demonstrated significant antitumor effects in preclinical and clinical studies. In this review, we discuss the regulatory mechanisms of cholesterol homeostasis and the impact of its dysregulation on the hallmarks of cancer. We also describe how cholesterol metabolism reprograms the TME across seven specialized microenvironments. Furthermore, we discuss the potential of targeting cholesterol metabolism as a therapeutic strategy for tumors. This approach not only exerts antitumor effects in monotherapy and combination therapy but also mitigates the adverse effects associated with conventional tumor therapy. Finally, we outline the unresolved questions and suggest potential avenues for future investigations on cholesterol metabolism in relation to cancer.

Abstract
BACKGROUND Early diagnosis and treatment are crucial to improve the prognosis of colorectal cancer (CRC). At present, there is a lack of an accurate CRC screening factor. We conducted folate receptor-positive circulating tumor cell analysis (FR + CTC analysis) in distinguishing CRC from benign colorectal diseases to evaluate the diagnostic efficiency. METHODS Clinical data of patients admitted to The First Affiliated Hospital of Anhui Medical University from January 2021 to July 2022 were retrospectively collected. Levels of FR + CTC and other indicators were analyzed. Receiver operating characteristic (ROC) analysis was performed to assess the diagnostic performance of these molecular biomarkers. RESULTS Data of 103 patients with CRC and 54 patients with benign colorectal diseases were collected. FR + CTC levels were observed significantly higher in CRC patients than in patients with benign colorectal diseases (P < 0.001). FR + CTC level was correlated with tumor diameter, differentiation, T-stage, pathological stage, clinical stage, and intravascular tumor thrombus in patients with CRC (P < 0.05). The optimal cutoff value of FR + CTC level for diagnosing CRC patients was 7.66 FU/3 ml, with a sensitivity of 85.4%, a specificity of 74.1%, and an Area Under Curve (AUC) of 0.855 (95% CI 0.77-0.923). In < 50-years old patients with CRC, the diagnostic efficiency of FR + CTC was excellent, with an AUC of 0.936 (95% CI 0.877-0.995). CONCLUSION FR + CTC counting has excellent diagnostic efficiency in screening of CRC. FR + CTC count can also predict the tumor stage of CRC patients before surgery, and guide the choice of treatment.

Abstract
BACKGROUND Colon cancer (CC) is one of the most common cancers of the digestive tract, the third most common cancer worldwide, and the second most common cause of cancer-related deaths. Previous studies have demonstrated a higher risk of lymph node metastasis (LNM) in young patients with CC. It might be reasonable to treat patients with early-onset locally advanced CC with extended lymph node dissection. However, few studies have focused on early-onset CC (ECC) patients with LNM. At present, the methods of predicting and evaluating the prognosis of ECC patients with LNM are controversial. AIM To compare the prognostic values of four lymph node staging indices and establish the best nomogram for patients with ECC. METHODS From the data of patients with CC obtained from the Surveillance, Epidemiology, and End Results (SEER) database, data of young patients with ECC (≤ 50 years old) was screened. Patients with unknown data were excluded from the study, while the remaining patients were included. The patients were randomly divided into a training group (train) and a testing group (test) in the ratio of 7:3, while building the model. The model was constructed by the training group and verified by the testing group. Using multiple Cox regression models to compare the prediction efficiency of LNM indicators, nomograms were built based on the best model selected for overall survival (OS) and cause-specific survival (CSS). In the two groups, the performance of the nomogram was evaluated by constructing a calibration plot, time-dependent area under the curve (AUC), and decision curve analysis. Finally, the patients were grouped based on the risk score predicted by the prognosis model, and the survival curve was constructed after comparing the survival status of the high and low-risk groups. RESULTS Records of 26922 ECC patients were screened from the SEER database. N classification, positive lymph nodes (PLN), lymph node ratio (LNR) and log odds of PLN (LODDS) were considered to be independent predictors of OS and CSS. In addition, independent risk factors for OS included gender, race, marital status, primary site, histology, grade, T, and M classification, while the independent prognostic factors for CSS included race, marital status, primary site, grade, T, and M classification. The prediction model including LODDS is composed of minimal Akaike information criterion, maximal concordance indexes, and AUCs. Factors including gender, race, marital status, primary site, histology, grade, T, M classification, and LODDS were integrated into the OS nomogram, while race, marital status, primary site, grade, T, M classification, and LODDS were included into the CSS nomogram. The nomogram representing both cohorts had been successfully verified in terms of prediction accuracy and clinical practicability. CONCLUSION LODDS is superior to N-stage, PLN, and LNR of ECC. The nomogram containing LODDS might be helpful in tumor evaluation and clinical decision-making, since it provides an appropriate prediction of ECC.

Abstract
PURPOSE Carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) are the most common tumor markers detected before and after gastric cancer (GC) surgery. However, the impact of post-preoperative CEA/CA19-9 increments on prognosis of GC remains unclear. In addition, there is no research incorporating post-preoperative CEA/CA19-9 increments into the prognostic model. METHODS Patients who underwent radical gastrectomy for GC at the First Affiliated Hospital of Anhui Medical University and Anhui Provincial Hospital from January 2013 to December 2017 were enrolled and divided into the discovery and validation cohort. Prognostic value of post-preoperative CEA/CA19-9 increments and preoperative CEA/CA199 levels were assessed by Kaplan-Meier log-rank analysis and compared by time-dependent receiver operating characteristic (t-ROC) curves. Multivariate Cox regression analysis was applied to establish the nomogram. The performance of the prognostic model was validated by the concordance index (C-index), calibration curve, and ROC curve analysis. RESULTS A total of 562 GC patients were included in this study. Overall survival (OS) rates decreased with an increasing number of incremental tumor markers after surgery. The t-ROC curves implied that the prognostic ability of the number of incremental post-preoperative tumor markers was superior to that of the number of positive preoperative tumor markers. Cox regression analysis suggested that the number of incremental post-preoperative tumor markers was an independent prognostic factor. The nomogram incorporated with the post-preoperative CEA/CA19-9 increments showed reliable accuracy. CONCLUSIONS Incremental post-preoperative CEA/CA19-9 were indicator of poor prognosis of GC. The prognostic value of post-preoperative CEA/CA19-9 increments exceed that of preoperative CEA/CA19-9 levels.

Abstract
Prediction of prognosis after radical resection of gastric cancer has not been well established. Therefore, we aimed to establish a prognostic model based on a new score system of patients with gastric cancer. A total of 1235 patients who underwent curative gastrectomy at our hospital from October 2015 to April 2017 were included in this study. Univariate and multivariate analyses were used to screen for prognostic risk factors. Construction of the nomogram was based on Cox proportional hazard regression models. The construction of the new score models was analyzed by the receiver operating characteristic curve (ROC curve), calibration curve, and decision curve. Multivariate analysis showed that tumor size, T, N, carcinoembryonic antigen, CA125, and CA19-9 were independent prognostic factors. The new score model had a greater AUC (The area under the ROC curve) than other systems, and the C-index of the nomogram was highly reliable for evaluating the survival of patients with gastric cancer. Based on the tumor markers and other clinical indicators, we developed a precise model to predict the prognosis of patients with gastric cancer after radical surgery. This score system can be helpful to both surgeons and patients.

Abstract
Background: The incidence of gastric cancer (GC) ranks fourth among all malignant tumors worldwide, and the fatality rate ranks second among all malignant tumors. Several Chinese traditional medicines have been used in the treatment of advanced gastric cancer. This study aims to investigate the effect of combinational use of natural product cryptotanshinone (CTS) with anti-cancer drug trifluorothymidine (FTD) in GC.Methods: Cell Counting Kit-8 assay was used to detect the inhibitory effect of the combinational or separate use of FTD and CTS on the growth of HGC-27 and AGS GC cells. The combined index of FTD and CTS was calculated using CompuSyn software. To understand the mechanism, we applied flow cytometry to study the cell cycle and cell apoptosis after treatment. We also investigated the amount of FTD incorporated into the DNA by immunofluorescence assay. The expression of relevant proteins was monitored using western blot. Furthermore, the effect of using TAS-102 in combination with CTS was studied in xenograft tumor nude mice model.Results: FTD and CTS inhibited the growth of GC cells in a dose-dependent manner, respectively. They both exhibited low to sub-micromolar potency in HGC-27 and AGS cells. The combination of FTD and CTS showed synergistic anticancer effect in HGC-27 cells and AGS cells. Our mechanism studies indicate that FTD could block HGC-27 cells at G2/M phase, while CTS could block HGC-27 cells at G1/G0 phase, while FTD combined with CTS could mainly block HGC-27 cells at G2 phase. FTD in combination with CTS significantly increased the apoptosis of HGC-27 cells. We observed that CTS treatment increased the incorporation of FTD into the DNA HGC-27 cell. FTD treatment activated STAT3 phosphorylation in HGC-27 cells, while CTS treatment down-regulated the concentration of p-STAT3. Interestingly, the combination of CTS and FTD reduced STAT3 phosphorylation induced by FTD. In the in vivo experiments, we observed that the combination of TAS-102 with CTS was significantly more potent than TAS-102 on tumor growth inhibition.Conclusions: FTD combined with CTS has a synergistic anti-gastric cancer effect as shown by in vitro and in vivo experiments, and the combined treatment of FTD and CTS will be a promising treatment option for advanced gastric cancer.

Abstract
BACKGROUND For the prognosis of patients with early gastric cancer (EGC), lymph node metastasis (LNM) plays a crucial role. A thorough and precise evaluation of the patient for LNM is now required.
AIM To determine the factors influencing LNM and to construct a prediction model of LNM for EGC patients.
METHODS Clinical information and pathology data of 2217 EGC patients downloaded from the Surveillance, Epidemiology, and End Results database were collected and analyzed. Based on a 7:3 ratio, 1550 people were categorized into training sets and 667 people were assigned to testing sets, randomly. Based on the factors influencing LNM determined by the training sets, the nomogram was drawn and verified.
RESULTS Based on multivariate analysis, age at diagnosis, histology type, grade, T-stage, and size were risk factors of LNM for EGC. Besides, nomogram was drawn to predict the risk of LNM for EGC patients. Among the categorical variables, the effect of grade (well, moderate, and poor) was the most significant prognosis factor. For training sets and testing sets, respectively, area under the receiver-operating characteristic curve of nomograms were 0.751 [95% confidence interval (CI): 0.721-0.782] and 0.786 (95%CI: 0.742-0.830). In addition, the calibration curves showed that the prediction model of LNM had good consistency.
CONCLUSION Age at diagnosis, histology type, grade, T-stage, and tumor size were independent variables for LNM in EGC. Based on the above risk factors, prediction model may offer some guiding implications for the choice of subsequent therapeutic approaches for EGC.

Abstract
BACKGROUND Gastric cancer (GC) is one of the most common malignant tumors. After resection, one of the major problems is its peritoneal dissemination and recurrence. Some free cancer cells may still exist after resection. In addition, the surgery itself may lead to the dissemination of tumor cells. Therefore, it is necessary to remove residual tumor cells. Recently, some researchers found that extensive intraoperative peritoneal lavage (EIPL) plus intraperitoneal chemotherapy can improve the prognosis of patients and eradicate peritoneal free cancer for GC patients. However, few studies explored the safety and long-term outcome of EIPL after curative gastrectomy.
AIM To evaluate the efficacy and long-term outcome of advanced GC patients treated with EIPL.
METHODS According to the inclusion and exclusion criteria, a total of 150 patients with advanced GC were enrolled in this study. The patients were randomly allocated to two groups. All patients received laparotomy. For the non-EIPL group, peritoneal lavage was washed using no more than 3 L of warm saline. In the EIPL group, patients received 10 L or more of saline (1 L at a time) before the closure of the abdomen. The surviving rate analysis was compared by the Kaplan-Meier method. The prognostic factors were carried out using the Cox appropriate hazard pattern.
RESULTS The basic information in the EIPL group and the non-EIPL group had no significant difference. The median follow-up time was 30 mo (range: 0-45 mo). The 1- and 3-year overall survival (OS) rates were 71.0% and 26.5%, respectively. The symptoms of ileus and abdominal abscess appeared more frequently in the non-EIPL group (P < 0.05). For the OS of patients, the EIPL, Borrmann classification, tumor size, N stage, T stage and vascular invasion were significant indicators. Then multivariate analysis revealed that EIPL, tumor size, vascular invasion, N stage and T stage were independent prognostic factors. The prognosis of the EIPL group was better than the non-EIPL group (P < 0.001). The 3-year survival rate of the EIPL group (38.4%) was higher than the non-EIPL group (21.7%). For the recurrence-free survival (RFS) of patients, the risk factor of RFS included EIPL, N stage, vascular invasion, type of surgery, tumor location, Borrmann classification, and tumor size. EIPL and tumor size were independent risk factors. The RFS curve of the EIPL group was better than the non-EIPL group (P = 0.004), and the recurrence rate of the EIPL group (24.7%) was lower than the non-EIPL group (46.4%). The overall recurrence rate and peritoneum recurrence rate in the EIPL group was lower than the non-EIPL group (P < 0.05).
CONCLUSION EIPL can reduce the possibility of perioperative complications including ileus and abdominal abscess. In addition, the overall survival curve and RFS curve were better in the EIPL group.

Abstract
BACKGROUND F-box and leucine-rich repeat 6 (FBXL6) have reportedly been associated with several cancer types. However, the role and mechanisms of FBXL6 in gastric cancer (GC) require further elucidation.
AIM To investigate the effect of FBXL6 in GC tissues and cells and the underlying mechanisms.
METHODS TCGA and GEO database analysis was performed to evaluate the expression of FBXL6 in GC tissues and adjacent normal tissues. Reverse transcription-quantitative polymerase chain reaction, immunofluorescence, and western blotting were used to detect the expression of FBXL6 in GC tissue and cell lines. Cell clone formation, 5-ethynyl-2’-deoxyuridine (EdU) assays, CCK-8, transwell migration assay, and wound healing assays were performed to evaluate the malignant biological behavior in GC cell lines after transfection with FBXL6-shRNA and the overexpression of FBXL6 plasmids. Furthermore, in vivo tumor assays were performed to prove whether FBXL6 promoted cell proliferation in vivo.
RESULTS FBXL6 expression was upregulated more in tumor tissues than in adjacent normal tissues and positively associated with clinicopathological characteristics. The outcomes of CCK-8, clone formation, and Edu assays demonstrated that FBXL6 knockdown inhibited cell proliferation, whereas upregulation of FBXL6 promoted proliferation in GC cells. Additionally, the transwell migration assay revealed that FBXL6 knockdown suppressed migration and invasion, whereas the overexpression of FBXL6 showed the opposite results. Through the subcutaneous tumor implantation assay, it was evident that the knockdown of FBXL6 inhibited GC graft tumor growth in vivo. Western blotting showed that the effects of FBXL6 on the expression of the proteins associated with the epithelial-mesenchymal transition-associated proteins in GC cells.
CONCLUSION Silencing of FBXL6 inactivated the EMT pathway to suppress GC malignancy in vitro. FBXL6 can potentially be used for the diagnosis and targeted therapy of patients with GC.

Abstract
BACKGROUND Nearly 66% of occurrences of gastric cancer (GC), which has the second-highest death rate of all cancers, arise in developing countries. In several cancers, the predictive significance of inflammatory markers has been established.
AIM To identify clinical characteristics and develop a specific nomogram to determine overall survival for GC patients.
METHODS Nine hundred and four GC patients treated at the First Affiliated Hospital of Anhui Medical University between January 2010 and January 2013 were recruited. Prognostic risk variables were screened for Cox analysis. The C index, receiver operator characteristic (ROC) curve, and decision curve analysis were used to evaluate the nomogram.
RESULTS Tumor node metastasis stage, carcinoembryonic antigen, systemic immune-inflammation index, and age were identified as independent predictive variables by multivariate analysis. Systemic immune-inflammation index value was superior to that of other inflammatory indicators. The ROC indicated the nomogram had a higher area under the curve than other factors, and its C-index for assessing the validation and training groups of GC patients was extremely reliable.
CONCLUSION We created a novel nomogram to forecast the prognosis of GC patients following curative gastrectomy based on blood markers and other characteristics. Both surgeons and patients can benefit significantly from this new scoring system.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most common type of liver cancer and has a high risk of invasion and metastasis along with a poor prognosis.
AIM To investigate the independent predictive markers for disease-free survival (DFS) in patients with HCC and establish a trustworthy nomogram.
METHODS In this study, 445 patients who were hospitalized in The First Affiliated Hospital of Anhui Medical College between December 2009 and December 2014 were retrospectively examined. The survival curve was plotted using the Kaplan–Meier method and survival was determined using the log-rank test. To identify the prognostic variables, multivariate Cox regression analyses were carried out. To predict the DFS in patients with HCC, a nomogram was created. C-indices and receiver operator characteristic curves were used to evaluate the nomogram's performance. Decision curve analysis (DCA) was used to evaluate the clinical application value of the nomogram.
RESULTS Longer DFS was observed in patients with the following characteristics: elderly, I–II stage, and no history of hepatitis B. The calibration curve showed that this nomogram was reliable and had a higher area under the curve value than the tumor node metastasis (TNM) stage. Moreover, the DCA curve revealed that the nomogram had good clinical applicability in predicting 3- and 5-year DFS in HCC patients after surgery.
CONCLUSION Age, TNM stage, and history of hepatitis B infection were independent factors for DFS in HCC patients, and a novel nomogram for DFS of HCC patients was created and validated.

Abstract
BACKGROUND Interleukin (IL)-34 is a pro-inflammatory cytokine involved in tumor development. The role of IL-34 in the proliferation and epithelial-mesenchymal transition (EMT) of gastric cancer (GC) remains to be investigated. AIM To investigate whether and how IL-34 affects the proliferation of GC cells and EMT. METHODS Using immunohistochemical staining, the expression of IL-34 protein was detected in 60 paired GC and normal paracancerous tissues and the relationship between IL-34 and clinicopathological factors was analyzed. The expression of IL-34 mRNA and protein in normal gastric epithelial cell lines and GC was detected using quantitative real-time polymerase chain reaction (qRT-PCR) and western blotting, respectively. Stable IL-34 knockdown and overexpression in AGS cell lines were established by lentiviral infection and validated by qRT-PCR and western blotting. The cholecystokinin-8 assay, clone formation assay, cell scratch assay, and transwell system were used to detect GC cell proliferation, clone formation, migration, and invasion capacity, respectively. The effects of IL-34 on the growth of GC transplant tumors were assessed using a subcutaneous transplant tumor assay in nude mice. The effects of IL-34 on the expression level of EMT-associated proteins in AGS cells were examined by western blotting. RESULTS Expression of IL-34 protein and mRNA was higher in GC cell lines than in GES-1 cells. Compared to matched normal paraneoplastic tissues, the expression of IL-34 protein was higher in 60 GC tissues, which was correlated with tumor size, T-stage, N-stage, tumor, node and metastasis stage, and degree of differentiation. Knockdown of IL-34 expression inhibited the proliferation, clone formation, migration, and invasion of AGS cells, while overexpression of IL-34 promoted cell proliferation, clone formation, migration, and invasion. Furthermore, the reduction of IL-34 promoted the expression of E-cadherin in AGS cells but inhibited the expression of vimentin and N-cadherin. Overexpression of IL-34 inhibited E-cadherin expression but promoted expression of vimentin and N-cadherin in AGS cells. Overexpression of IL-34 promoted the growth of subcutaneous transplanted tumors in nude mice. CONCLUSION IL-34 expression is increased in GC tissues and cell lines compared to normal gastric tissues or cell lines. In GC cells, IL-34 promoted proliferation, clone formation, migration, and invasion by regulating EMT-related protein expression cells. Interference with IL-34 may represent a novel strategy for diagnosis and targeted therapy of GC.

Abstract
BACKGROUND In recent years, the incidence of types II and III adenocarcinoma of the esophagogastric junction (AEG) has shown an obvious upward trend worldwide. The prognostic prediction after radical resection of AEG has not been well established.
AIM To establish a prognostic model for AEG (types II and III) based on routine markers.
METHODS A total of 355 patients who underwent curative AEG at The First Affiliated Hospital of Anhui Medical University from January 2014 to June 2015 were retrospectively included in this study. Univariate and multivariate analyses were performed to identify the independent risk factors. A nomogram was constructed based on Cox proportional hazards models. The new score models was analyzed by C index and calibration curves. The receiver operating characteristic (ROC) curve was used to compare the predictive accuracy of the scoring system and tumor-node-metastasis (TNM) stage. Overall survival was calculated using the Kaplan-Meier curve amongst different risk AEG patients.
RESULTS Multivariate analysis showed that TNM stage (hazard ratio [HR] = 2.286, P = 0.008), neutrophil-to-lymphocyte ratio (HR = 2.979, P = 0.001), and body mass index (HR = 0.626, P = 0.026) were independent prognostic factors. The new scoring system had a higher concordance index (0.697), and the calibration curves of the nomogram were reliable. The area under the ROC curve of the new score model (3-year: 0.725, 95% confidence interval [CI]: 0.676-0.777; 5-year: 0.758, 95%CI: 0.708-0.807) was larger than that of TNM staging (3-year: 0.630, 95%CI: 0.585-0.684; 5-year: 0.665, 95%CI: 0.616-0.715).
CONCLUSION Based on the serum markers and other clinical indicators, we have developed a precise model to predict the prognosis of patients with AEG (types II and III). The new prognostic nomogram could effectively enhance the predictive value of the TNM staging system. This scoring system can be advantageous and helpful for surgeons and patients.

Abstract
BACKGROUND Gastric cancer (GC) is common in East Asia, yet its molecular and pathogenic mechanisms remain unclear. Circular RNAs (circRNAs) are differentially expressed in GC and may be promising biomarkers. Here, we investigated the role and regulatory mechanism of circTMC5 in GC. METHODS CircTMC5 expression was detected in human GC and adjacent tissues using microarray assays and qRT-PCR, while the clinicopathological characteristics of patients with GC were used to assess its diagnostic and prognostic value. The circTMC5/miR-361-3p/RABL6 axis was examined in vitro and vivo, and the immune roles of RABL6 were evaluated using bioinformatics analyses and immunohistochemistry (IHC). RESULTS CircTMC5 was highly expressed in GC tissues, plasma, and cell lines, and was closely related to histological grade, pathological stage, and T classification in patients with GC. CircTMC5 expression was also an independent prognostic factor for GC and its combined detection with carcinoembryonic antigen may improve GC diagnosis. Low circTMC5 expression correlated with good prognosis, inhibited GC cell proliferation, and promoted apoptosis. Mechanistically, circTMC5 overexpression promoted GC cell proliferation, invasion, and metastasis but inhibited apoptosis by sponging miR-361-3p and up-regulating RABL6 in vitro and vivo, whereas miR-361-3p up-regulation had the opposite effects. RABL6 was highly expressed in GC and was involved in immune regulation and infiltration in GC. CONCLUSIONS CircTMC5 promotes GC and sponges miR-361-3p to up-regulate RABL6 expression, thus may have diagnostic and prognostic value in GC. RABL6 also displays therapeutic promise due to its role in the immune regulation of GC.

BACKGROUND Approximately 90% of new cases of noncardiac gastric cancer (GC) are related to Helicobacter pylori (H. pylori), and cytotoxin-associated gene A (CagA) is one of the main pathogenic factors. Recent studies have shown that the pharmacological effects of cryptotanshinone (CTS) can be used to treat a variety of tumors. However, the effects of CTS on H. pylori, especially CagA+ strain-induced gastric mucosal lesions, on the development of GC is unknown.
AIM To assess the role of CTS in CagA-induced proliferation and metastasis of GC cells, and determine if CagA+ H. pylori strains causes pathological changes in the gastric mucosa of mice.
METHODS The effects of CTS on the proliferation of GC cells were assessed using the Cell Counting Kit-8 (CCK-8) assay, and the abnormal growth, migration and invasion caused by CagA were detected by CCK-8 and transwell assays. After transfection with pSR-HA-CagA and treatment with CTS, proliferation and metastasis were evaluated by CCK-8 and transwell assays, respectively, and the expression of Src homology 2 (SH2) domain–containing phosphatase 2 (SHP2) and phosphorylated SHP2 (p-SHP2) was detected using western blotting in AGS cells. The enzyme-linked immunosorbent assay was used to determine the immunoglobulin G (IgG) level against CagA in patient serum. Mice were divided into four groups and administered H. pylori strains (CagA+ or CagA-) and CTS (or PBS) intragastrically, and establishment of the chronic infection model was verified using polymerase chain reaction and sequencing of isolated strains. Hematoxylin and eosin staining was used to assess mucosal erosion in the stomach and toxicity to the liver and kidney.
RESULTS CTS inhibited the growth of GC cells in dose- and time-dependent manners. Overexpression of CagA promoted the growth, migration, and invasion of GC cells. Importantly, we demonstrated that CTS significantly inhibited the CagA-induced abnormal proliferation, migration, and invasion of GC cells. Moreover, the expression of p-SHP2 protein in tumor tissue was related to the expression of IgG against CagA in the serum of GC patients. Additionally, CTS suppressed the protein expression levels of both SHP2 and p-SHP2 in GC cells. CTS suppressed CagA+ H. pylori strain-induced mucosal erosion in the stomach of mice but had no obvious effects on the CagA- H. pylori strain group.
CONCLUSION CTS inhibited CagA-induced proliferation and the epithelial-mesenchymal transition of GC cells in vitro, and CagA+ H. pylori strains caused mucosal erosions of the stomach in vivo by decreasing the protein expression of SHP2.

Abstract
Background The prognosis of colon cancer (CC) is challenging to predict due to its highly heterogeneous nature. Ferroptosis, an iron-dependent form of cell death, has roles in various cancers; however, the correlation between ferroptosis-related genes (FRGs) and prognosis in CC remains unclear. Methods The expression profiles of FRGs and relevant clinical information were retrieved from the Cancer Genome Atlas (TCGA) database. Cox regression analysis and the least absolute shrinkage and selection operator (LASSO) regression model were performed to build a prognostic model in TCGA cohort. Results Ten FRGs, five of which had mutation rates ≥ 3%, were found to be related to the overall survival (OS) of patients with CC. Patients were divided into high- and low-risk groups based on the results of Cox regression and LASSO analysis. Patients in the low-risk group had a significantly longer survival time than patients in the high-risk group (P < 0.001). Enrichment analyses in different risk groups showed that the altered genes were associated with the extracellular matrix, fatty acid metabolism, and peroxisome. Age, risk score, T stage, N stage, and M stage were independent predictors of patient OS based on the results of Cox analysis. Finally, a nomogram was constructed to predict 1-, 3-, and 5-year OS of patients with CC based on the above five independent factors. Conclusion A novel FRG model can be used for prognostic prediction in CC and may be helpful for individualized treatment.

Abstract
Background The prognosis of patients with hepatocellular carcinoma (HCC) remains difficult to accurately predict. The purpose of this study was to establish a prognostic model for HCC based on a novel scoring system. Methods Five hundred and sixty patients who underwent a curative hepatectomy for treatment of HCC at our hospital between January 2007 and January 2014 were included in this study. Univariate and multivariate analyses were used to screen for prognostic risk factors. The nomogram construction was based on Cox proportional hazard regression models, and the development of the new scoring model was analyzed using receiver operating characteristic (ROC) curve analysis and then compared with other clinical indexes. The novel scoring system was then validated with an external dataset from a different medical institution. Results Multivariate analysis showed that tumor size, portal vein tumor thrombus (PVTT), invasion of adjacent tissues, microvascular invasion, and levels of fibrinogen and total bilirubin were independent prognostic factors. The new scoring model had higher area under the curve (AUC) values compared to other systems, and the C-index of the nomogram was highly consistent for evaluating the survival of HCC patients in the validation and training datasets, as well as the external validation dataset. Conclusions Based on serum markers and other clinical indicators, a precise model to predict the prognosis of patients with HCC was developed. This novel scoring system can be an effective tool for both surgeons and patients.

Abstract
ABSTRACT This study aimed to explore the significance and prognostic value of serum tumor-associated carbohydrate antigen 19-9 (CA19-9), D-dimer, and tumor necrosis factor alpha-induced protein 3 (TNFAIP3/A20) in patients with pancreatic ductal adenocarcinoma (PDAC).Our study included 148 patients treated for PDAC at Northern Jiangsu People's Hospital Affiliated to Yangzhou University from January 2012 to December 2016. Cutoff prognostic values were predicted using the receiver operating characteristic (ROC) curve. The Kaplan-Meier method was used to assess the survival rates of patients. Univariate and multivariate COX regression analyses were used to evaluate the prognostic factors.The recommended cutoff values of neutrophil-lymphocyte rate (NLR), platelet-lymphocyte rate (PLR), CA19-9, and D-dimer were 2.04 (sensitivity, 0.59; specificity, 0.9; area under the ROC curve [AUC], 0.749; P < .001), 52.94 (sensitivity, 0.73; specificity, 0.95; AUC, 0.829; P < .001), 176.66 U/mL (sensitivity, 0.7; specificity, 0.9; AUC, 0.794; P < .001), and 1.18 mg/L (sensitivity, 0.82; specificity, 0.9; AUC, 0.845; P < .001), respectively. Positive TNFAIP3/A20 expression was considered as an inclusion criterion. Serum CA19-9 expression was related with lymph node metastasis (P = .010), tumor-lymph node-metastasis (TNM) stage (P < .001), and survival rate (P < .001). D-dimer was correlated with tumor differentiation grade (P = .014), tumor size (P = .045), TNM stage (P < .001), and survival rate (P < .001). TNFAIP3/A20 was correlated with tumor differentiation grade (P < .001), body mass index (BMI) (P < .001), TNM stage (P = .014), and survival rate (P < .001). Kaplan-Meier curves showed that PDAC patients had significant differences in CA19-9, D-dimer, and TNFAIP3/A20 expressions (P < .05). CA19-9, D-dimer, TNM stage, tumor differentiation grade, and TNFAIP3/A20 were independent prognostic markers for PDAC in univariate and multivariate COX analyses.CA19-9, D-dimer, and TNFAIP3/A20 were found to be independent prognostic markers for PDAC patients.

Abstract
PURPOSE The prognosis for colorectal cancer (CRC) patients is drastically impacted by the presence of lymph node or liver metastases at diagnosis or resection. On this basis it is sought to identify novel proteins as biomarkers and determinants of CRC metastasis. EXPERIMENTAL DESIGN Proteomic analyses are undertaken using primary tissues from ten Chinese CRC patients presenting with or without liver metastases and immunohistochemistry used to validate selected proteins in an independent patient cohort. RESULTS Comparing CRC against paired normal adjacent tissues identifies 1559 differentially expressed proteins (DEPs) with 974 upregulated and 585 downregulated proteins, respectively. The highest number of DEPs is selectively associated with metastatic tumors (519 upregulated and 267 downregulated proteins, respectively) with a smaller number of unique DEPs identified only in non-metastatic CRC cases (116 upregulated and 29 downregulated proteins, respectively). The remaining DEPs are commonly expressed in both non-metastatic and metastatic tumors. The upregulation of three representative DEPs (S100A11, S100P, and RBM25) is confirmed using immunohistochemistry against 154 CRC tissues embedded in a tissue microarray. CONCLUSIONS AND CLINICAL RELEVANCE The data reveal both previously identified CRC biomarkers along with novel candidates which provide a ready resource of DEPs in CRC for further investigation.

Abstract
Colon cancer is the third leading cause of cancer-related deaths all around the world. LncRNA methylation has been verified to participate in some kinds of malignancies. The aim of this study was to investigate the function of NEAT1 in colon cancer and further explore the potential mechanism between NEAT1 and ALKBH5. Differential expression of lncRNAs between colon cancer tissues and normal tissues was identified using ArrayStar lncRNA microarrays. The levels of NEAT1 and ALKBH5 expression in colon cancer tissues and cells were measured using qRT-PCR. MTT, transwell migration assays and qRT-PCR were performed to detect cell proliferation and migration. Flow cytometry and qRT-PCR was used for apoptosis analysis. Then, m6A RNA immunoprecipitation was performed to detect methylated NEAT1 in colon cancer cells. The results showed NEAT1 was remarkably enhanced in colon cancer tissues and correlated with poor prognosis. Knockdown of NEAT1 inhibited cell proliferation and migration, induced cell apoptosis in colon cancer cell lines. Besides, ALKBH5 could upregulate NEAT1 expression by demethylation. In addition, ALKBH5 knockdown suppressed malignant behavior of colon cancer partially through NEAT1 in vitro and vivo. In a word, we observed NEAT1 expression level was up-regulated in colon cancer tissues and cells. ALKBH5 knockdown suppressed malignant behavior of colon cancer partially through NEAT1 by demethylation in vitro and vivo, suggesting that ALKBH5-NEAT1 axis maybe potential therapeutic target for colon cancer treatment.

Abstract
Background: The prognostic prediction after radical resection of pancreatic ductal adenocarcinoma (PDAC) has not been well-established. We aimed to establish a prognostic model for PDAC based on a new score system, which included a clinical routine serum marker. Methods: A total of 438 patients who underwent curative PDAC at the First Affiliated Hospital of Anhui Medical University from January 2007 to January 2014 were included in this study. Univariate and multivariate analyses were used to screen for prognostic risk factors. We constructed the nomogram based on Cox proportional hazard regression models. The construction of the new score models was analyzed by the receiver operator characteristic curve (ROC curve), which were compared with other clinical indexes. Results: Multivariate analysis showed that TNM stage, CA199, CEA, globulin, neutrophil-to-lymphocyte ratio (NLR), and lymphocyte-to-monocyte ratio (LMR) were independent prognostic factors. The new score system had a higher AUC value than other risk factors, and the C-index of the nomogram was highly consistent for evaluating survival of PDAC patients in the validation groups and training group, and the external population also verified the nomogram. Conclusions: For the patients with PDAC after radical surgery, we developed a precise model to predict the prognosis based on the serum markers and other clinical indicators. For surgeons and patients, this score system can be an effective help.

Abstract
Increasing researches have focused on the biological functions of long noncoding RNAs (lncRNAs) in human cancers. HOXA11-AS, a widely known lncRNA, has been confirmed to be involved in the progression of several cancers, including gastric cancer (GC). Whereas, the detailed mechanism of this lncRNA in GC remains to be further illuminated. The abundances of HOXA11-AS, miR-148a and WNT1 in GC tissues and cell lines were examined by qRT-PCR. Clinicopathological and Kaplan-Meier survival analyses were determined to explore the relationship between HOXA11-AS expression and outcomes of patients. Transwell assay was performed for the evaluation of cell migration and invasion. Bioinformatics, dual-luciferase reporter and RNA immunoprecipitation assays were employed to analyze the correlation between HOXA11-AS and miR-148a or miR-148a and WNT1. The protein levels of WNT1 and β-catenin were assessed by western blot assay. Results showed that HOXA11-AS and WNT1 expression levels were upregulated, while miR-148a level was downregulated in GC tissues and cell lines relative to matched controls. Elevated expression of HOXA11-AS was associated with increased tumor size, lymph node metastasis, advanced TNM stage, as well as reduced survival of GC patients. HOXA11-AS induced migration and invasion of GC cells through serving as a molecular sponge for miR-148a. Furthermore, miR-148a inactivated WNT1/β-catenin signaling pathway via directly targeting WNT1. HOXA11-AS increased WNT1/β-catenin pathway activity, which was abolished by miR-148a overexpression in GC cells. In conclusion, overexpression of HOXA11-AS contributed to migration and invasion of GC cells via activation of WNT1/β-catenin signaling pathway through repressing miR-148a, providing a prospective therapeutic target for GC.

Abstract
Background: Besides the well-established risk factors for gastric adenocarcinoma (GaC), many other etiological factors remain largely unexplored. This large comprehensive case-control study aimed to investigate the preventable lifestyle and eating habits associated with GaC. Methods: Consecutive patients with primary microscopically-confirmed GaC diagnosed in 2016-2018 were matched by sex, age, height, and socioeconomic status at a 1:1 ratio with healthy controls. Association of GaC versus control with investigated factors was assessed using the multivariable-adjusted conditional logistic regression for paired samples. Results: Together 302 GaC patients and 302 healthy controls were investigated. Participants receiving higher education and those eating majorly vegetables had less frequently GaC. The majorly frying cooking habit was associated with a higher incidence of GaC. People complaining about poor sleep quality had more often GaC. The more often one smoked, the more often he/she had GaC. A higher frequency for having pickled food was associated with more frequent GaC, while having more frequently vegetables/fruit, beans, or kelps was associated with less often GaC. A greater preference for sour or bitter taste was associated with less frequent GaC. The frequencies of thin liquid intake after meal, swallowing hot food without adequate cooling, doing other things while eating, eating overnight food, and eating midnight snack were all positively associated with GaC, while going to bed regularly was associated with less often GaC. Conclusions: Education level, sleep quality, smoking, the frequencies of use of several foods and seasonings, the preference for specific tastes, and various eating and living habits were associated with GaC. The findings offer important hints for further prospective investigations and for easy effective GaC-preventative strategy-making.

Abstract
Purpose PRDX (Peroxiredoxin) family has involved in breast cancer tumorigenesis from the evidence obtained from cell lines, human tissues and mouse models. Nonetheless, the diversified expression patterns, coupled with the prognostic values of PRDX family, still require explanation. This study aimed at investigating the clinical importance and biological of PRDXs in breast cancer. Patients and methods Specimens of paraffin sections used for immunohistochemistry were collected from the hospital and the remaining patient information was retrieved from online databases. The expression and survival data of PRDXs in patients with breast cancer were from ONCOMINE, GEPIA, Kaplan–Meier Plotter. cBioPortal, Metascape, String, Cytoscape and DAVID were used to predict functions and pathways of the changes in PRDXs and their frequently altered neighbor genes. Immunohistochemistry was used to detect the expression of PRDXs in breast cancer. Results We discovered the expression levels of PRDX1-5 were higher in breast cancer tissues than in normal tissues, whereas the expression level of PRDX6 was observed as lower in the former one in comparison with that of the latter one. There existed a correlation between the expression levels of PRDX4, 5 and the advanced tumor stage. Survival analysis revealed that the expression of PRDXs were all associated with relapse-free survival (RFS) in all of the patients with breast cancer. Eventually, we discovered significant regulation of the cellular oxidant detoxification and detoxification of ROS by the PRDX changes, together with obtaining the core modules of genes (TXN, TXN2, TXNRD1, TXNRD2, GPX1 and GPX2) linked to the PRDX family of genes in breast cancer. Conclusion The PRDX family is widely involved in the development of breast cancer and affects the prognosis of patients. The functions and pathways of the changes in PRDXs and their frequently altered neighbor genes can be further verified by wet experiments.

Abstract
Background Blood counting and the liver function tests, as the routine examinations, can reflect the immune and nutritional status of the body, our aim is to assess the prognostic significance of serum gamma-glutamyltransferase (GGT) levels and AST/ALT in primary hepatic carcinoma. Methods Clinico-pathological data of 414 patients with primary hepatic carcinoma in the 1st Affiliated Hospital of Anhui Medical College between January 2007 to January 2014 was analyzed retrospectively in this study. Survival curves were described by Kaplan-Meier method and compared by Log-rank test, univariate and multivariate analysis were used to identify the prognostic factors. Results GGT was positively correlated with the tumor size(P = 0.000), tumor volume (P = 0.000), tumor volume percent (P = 0.004), TNM stage(P = 0.009), 1-year survival rate (P = 0.000), 3- years survival rate (P = 0.000) and 5-years survival rate(P = 0.000). The serum ALT/AST was significantly correlated with age (P = 0.047), tumor size(P = 0.002), tumor volume (P = 0.010), tumor volume percent (P = 0.005), TNM stage(P = 0.006), liver cirrhosis(P = 0.003), 3- years survival rate (P = 0.032) and 5-years survival rate(P = 0.000). The Kaplan-Meier curves showed that the patients with primary hepatic carcinoma had a longer time in the low GGT group and low AST/ALT group, showing a significant difference (P < 0.05). The univariate and multivariate analyses showed that TNM stage, differentiation grade, tumor volume, GGT and AST/ALT were independent factors for predicting overall survival rate of primary hepatic carcinoma patients. Conclusions GGT and AST/ALT were independent factors for predicting overall survival rate of primary hepatic carcinoma patients.

Abstract
BACKGROUD Inflammation can promote tumor growth, invasion, angiogenesis and even metastasis. Inflammatory markers have prognostic value in some malignancies. The aim of the present study was to examine whether neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) served as sensitive serum markers for predicting lymph node metastasis and prognostic factors in gastric cancer (GC) patients. METHODS 904 consecutive patients who underwent radical total or subtotal gastrectomy between 2010 and 2011, were included in this study. The clinical utility of the NLR and PLR was evaluated by receiver operating characteristic (ROC) curves,Kaplan-Meier curves and Cox regression analyses were used to calculate the overall survival (OS) characteristics. RESULTS We determined the cutoff values of NLR and PLR was 2.0 and 160 respectively according to the ROC curve. Both the NLR and PLR were significantly associated with LN (lymph node) metastasis, and high NLR and PLR groups were significantly associated with poor overall survival. Additionally, NLR and TNM stage were independent prognostic factors for overall survival, however, PLR had limited value. CONCLUSIONS NLR and PLR levels may be valuable indexes for lymph node metastasis. Although both the PLR and NLR may have prognostic value of gastric cancer patients, NLR is better to predict overall survival than PLR.

Abstract
Gastric cancer (GC) is one of the most common digestive malignancies globally, and the prognosis of patients with advanced tumors remains poor. Isocryptotanshinone (ICTS), isolated from Salvia miltiorrhiza, was found to inhibit the proliferation of lung and breast cancer cells. However, whether ICTS has anticancer activities against GC is unknown. In the present study, we reported that the proliferation of GC cells was inhibited by ICTS in a dose- and time-dependent manner. After treatment with ICTS, GC cells were arrested in the G1/G0 phase of cell cycle and the apoptotic cells were induced in a dose-dependent manner. Additionally, ICTS suppressed the expression of cell cycle- and apoptosis-associated proteins (e.g., Cyclin D1, phosphorylated Rb, E2F1, Mcl-1, Bcl-2, and Survivin). ICTS inhibited the phosphorylation of STAT3 in a dose-dependent manner. Down-regulated STAT3 attenuated the expression of Cyclin D1, p-Rb, and Survivin, which remarkably increased the sensitivity of ICTS in GC cells; overexpression of STAT3 restored the cell growth and proliferation and the protein expression suppressed by ICTS. ICTS also suppressed the xenograft tumor growth in BALB/c nude mice. Together, these data indicate that ICTS inhibits GC proliferation by inducing G1/G0 cell cycle arrest and apoptosis via inhibiting the STAT3 signaling pathway.

Abstract
Objective: To investigate the serotype distribution and antimicrobial susceptibility pattern of Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae) and Moraxella catarrhalis (M. catarrhalis) isolates collected from nasopharyngeal swabs from Uygur children in Kashi. Methods: Nasopharyngeal swabs were collected from inpatient Uygur children aged from 1 month to 5 years with respiratory infections from the pediatric department, the First People's Hospital of Kashi, Xinjiang Uygur Autonomous Region. Antimicrobial susceptibilities of the isolates were determined with E-test and KB disk diffusion methods. The production of β-lactamase was detected for H. influenzae and M. catarrhalisisolates using nitrocefin disc method. Quellung test and latex agglutination test were adopted to identify serotypes of S. pneumoniae and H. influenzae isolates. Results: Forty-seven S. pneumoniae, 13 H. influenzae and 16 M. catarrhalis isolates were detected. All of the 47 S. pneumoniae isolates were sensitive to parenteral penicillin, amoxicillin-clavulanic acid, vancomycin and levofloxacin; the susceptibility rates to cefotaxime, imipenem and chloramphenicol were 94% (44/47), 89% (42/47), and 98% (46/47). The resistance rate to erythromycin was 74% (35/47). The most common serotype of S. pneumoniae was serotype 19A (10 strains, 21%). The coverage rate of 13-valent conjugate vaccine (PCV13) was 70% (33/47). None of the 13 H. influenzae isolates could be typed. They were highly susceptible to tested β-lactams antibiotics, except ampicillin. Only one H. influenzae isolate could produce β-lactamase, and two isolates were identified as β-lactamase-negative-ampicillin-resistant ones. The sixteen M. catarrhalis isolates were all positive in β-lactamase detection, but sensitive to amoxicillin-clavulanic acid, cephalosporins and meropenem. Conclusions: In Kashi, Xinjiang Uygur Autonmous Region, S. pneumoniae isolates from Uygur children were highly sensitive to parenteral penicillin and other β-lactams antibiotics. H. influenzae isolates from Uygur children were highly susceptible to amoxicillin-clavulanic acid, cephalosporins and ciprofloxacin. All M. catarrhalis isolates from Uygur children could produce β-lactamase, but were sensitive to the enzyme inhibitors and cephalosporins.

Abstract
AIMS To propectively reveal the clinicopathological and prognostic significances of monocyte-lymphocyte ratio (MLR), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in resected patients with non-metastatic Siewert type II/III adenocarcinoma of esophagogastric junction (AEG). METHODS A total of 611 patients diagnosed with Siewert type II/III AEG and undergoing surgery between 2006 and 2011 were prospectively followed-up until April 2016. Associations between preoperative peripheral MLR, NLR, and PLR and clinicopathological parameters were quantified using the multivariate Logistic regression model with adjustment. The correlation between the 3 ratios and cancer-specific survival (CSS) was investigated using the univariate and adjusted multivariate Cox regression models with stratifications. The periodical survival rates for the low- and high-level arms were obtained using the Kaplan-Meier method. RESULTS We set the medians (0.223, 2.22, and 124.4) as the cut-off values of preoperative MLR, NLR, and PLR, respectively. MLR was higher in male patients and those > 63 years; PLR was higher in patients with type II tumors. The (marginally-)significantly inverse ratio-CSS association was detected in male patients, those ≤ 63 years, those with type III tumors, and those with pTNM stage III tumors for MLR, and in female patients, those > 63 years, those with type III tumors, those with vessel invasion, and those with stage III tumors for NLR, but was generally negative concerning PLR. The association majorly existed in type III and pTNM stage III tumors. CONCLUSION MLR and NLR might be prognostic factors for patients with non-metastatic Siewert type II/III AEG, while PLR had limited significance.

Abstract
Objective To prospectively investigate associations of presurgical body mass index (BMI) with clinicopathological factors and its prognostic significance in radically D2-resected patients with non-metastasized gastric cancer (GC) and Siewert type II/III adenocarcinoma of esophagogastric junction (AEG). Methods A large prospective cohort consisting of radically-resected GC and AEG patients was analyzed. Follow-up was successful in 671 out of 700 patients, who were categorized into underweight (BMI<18.5), normal-weight (BMI=18.5-22.9), overweight (BMI=23-24.9), and obese (BMI≥25) groups according to Asian standards. BMI-associated factors were explored using multivariable logistic regression with adjustment. Cancer-specific survival analyses were conducted applying both univariable and multivariable Cox regression methods. Results Pre-operation, higher hemoglobin levels and smaller anemia proportions were observed in larger BMI groups. Higher BMI tended to be associated with higher neutrophil-lymphocyte ratios (NLRs). Patients with higher BMI had smaller tumors and more often stage I tumors, but longer surgical time and postsurgical stay. In multivariable analyses, higher hemoglobin levels, upper tumor location, poorer differentiation, and higher NLR were significantly associated with higher BMI. Overall, survival analyses revealed no significant role of BMI. However, in further stratifications after adjustment, compared to patients with normal BMI, obese patients had better survival in women, but worse in those with AEG; underweight was associated with reduced mortality risk in tumors differentiated well to moderately; overweight patients had increased death hazard when having thrombocytopenia. Conclusion Overall, preoperative BMI had limited prognostic significance in operated GC patients. However, under specific conditions (e.g., female, AEG, good differentiation, and thrombocytopenia), BMI might indicate postoperative survival.

Abstract
INTRODUCTION Estrogen receptor positive (ER+) breast cancer (BC) is highly hormonal therapy-responsive. The choice between neoadjuvant hormonal therapy (NHT) and neoadjuvant chemotherapy (NCT) remains controversial. The aim of this meta-analysis was to evaluate benefits and safety of NHT compared with NCT for operable BC patients. Areas covered: Electronic databases were searched to identify randomized clinical trials (RCTs) comparing NHT and NCT for treatment of invasive and immunohistochemically ER+ BC. Major outcomes were clinical response rate, pathologic complete response (pCR), operation methods, recurrence, and adverse events. Five RCTs were included. The clinical response rates between NHT and NCT were not statistically different overall, or in ER-rich patients or postmenopausal women. Compared with NCT, NHT had a significant reduction of complete response rate and an increment in progressive disease rate. NHT increased rates of breast conserving surgery (BCS) and wide local excision (WLE) compared with NCT. All the other parameters were comparable. Patients receiving NHT had better tolerance than those undergoing NCT. Expert commentary: When treating BC, NHT was well tolerated, and contributed to more BCS and WLE cases, especially in ER-rich postmenopausal patients. While for those who are eligible for chemotherapy, NCT might be better recommended due to higher response rates.

Abstract
Lysine methylation plays a vital role in histone modification. Deregulations of lysine methyltransferases and demethylases have been frequently observed in human cancers. The SET and MYND domain containing protein 3 (SMYD3) is a novel histone lysine methyltransferase and it functions by regulating chromatin during the development of myocardial and skeletal muscle. It has been recently unveiled to play significant roles in human cancer genesis and progression via regulating various key cancer-associated genes and pathways and promoting cell proliferation and migration. Upregulation of SMYD3 expression is present in multiple cancer types, suggesting it as a potential prognostic marker. Herein the structure, substrates and targets of SMYD3, and its effects on initiation, invasion and metastasis of diverse tumors (e.g., esophageal squamous cell carcinoma, gastric cancer, hepatocellular carcinoma, cholangiocarcinoma, breast cancer, prostate cancer, and leukemia) are systematically reviewed, providing clues for the development of novel SMYD3-specific personalized anti-cancer therapy. SMYD3 inhibitors (e.g., BCI-121 and novobiocin) could hopefully fight against tumors with efficacy.

Abstract
Hirschsprung’s disease (HD) is an intestinal malformation caused by the innate absence of ganglion cells in the neural plexus of the colorectal wall, and is most common in male infants. It is rare in adult, and is usually left-sided. Herein we reported based on the CARE guidelines a case of a 47-year-old adult female suffering from “right-sided” HD complicated by refractory hypertension and cough. The patient with a history of cesarean section and with digestive unfitness (abdominal pain, distention, and constipation) only since 20 years old had recurrence of HD after initial surgery due to the incomplete removal of the HD-affected bowel based on a diagnosis of “chronic ileus”, leading to the relapse of the digestive symptoms and the emergence of some intractable circulatory and respiratory complications which could be hardly controlled by conservative treatment. During the long interval before coming to our department for help, she had been re-hospitalized for several times with various misdiagnoses and supplied merely with symptomatic treatment which could only achieve temporary symptomatic relief. At her admission to our department, the imaging examinations strongly indicated recurrent HD which was further supported by pathological examinations, and right hemi-colectomy was performed to remove the remnant aganglionic intestinal segment. Intraoperative and postoperative pathology supported the completeness of the definitive resection. Post-operation, the patient’s bowel motility significantly improved, and interestingly, the complications disappeared. For adult patients with long-term constipation combined with cough and hypertension, rare diseases like HD which requires definite surgery and which could be “right-sided” should not be overlooked. It is vital to diagnose and cure HD patients in childhood. Through the comparison of the two surgeries, it is noteworthy that for diagnosed HD, sufficient removal of the non-functional intestine confirmed by intraoperative pathology is essential.

Abstract
Background Adenocarcinoma of esophagogastric junction (AEG) was initially proposed in 1999 by Siewert. During recent decades, the incidence and prevalence of AEG were arising globally whereas the incidence of gastric cancer is gradually declining. Complete blood counting and liver function tests, as the routine examination of immune and nutritional status, were reported to be the predictors of overall survival (OS) in some tumors. However, little is known about the prognostic significance of these indexes in AEG patients. The purpose of this study was to assess the prediction of preoperative pre-albumin, hemoglobin, and prognostic nutritional index (PNI) for survival outcomes in AEG patients. Methods A retrospective cohort of 101 AEG patients followed by radical surgery was recruited between January and July 2010. Clinical and laboratory data were obtained and used to evaluate the predictive value through survival analysis. Receiver operating characteristic (ROC) curve analysis determined 200 mg/L, 120 g/L, 5 cm, and 51 as the cutoff values of pre-albumin, hemoglobin, tumor size, and PNI, respectively. Results Univariate analysis revealed that AEG patients with hemoglobin ≥120 g/L, albumin ≥40 g/L, pre-albumin ≥200 g/L, PNI ≥51, and tumor size <5 cm had longer OS (P < 0.05). Additionally, pre-albumin, tumor size, and TNM stage were demonstrated to be independent prognostic indicators by multivariate analysis with Cox regression, and the performance of pre-albumin for predicting OS in AEG patients was further identified by ROC curves (P = 0.006). Conclusions Preoperative pre-albumin was an independent prognostic factor, and a high level of pre-albumin predicted longer OS in AEG patients.

Abstract
AIM To assess the value of transabdominal ultrasound (TUS) in the preoperative assessment of adenocarcinoma of the esophagogastric junction (AEG).
METHODS A total of 65 patients who underwent TUS and computed tomography (CT) preoperatively and were pathologically diagnosed with AEG after surgery from December 2014 to May 2016 were included in this study. The TUS or CT results were compared with pathological findings.
RESULTS With regard to Siewert's classification, the diagnostic accuracy of TUS in AEG was 90.8% (85.7% for type Ⅰ and 92.2% for non-type Ⅰ). The accuracy of TUS and CT in T-staging of AEG was 33.8% and 63.1%, respectively, and there was a significant difference between the two diagnostic modalities (P < 0.05), although there was no significant difference in accuracy of N-staging and M-staging between CT and TUS (P > 0.05). For those who were preoperatively diagnosed with poorly differentiated adenocarcinoma, there was no significant difference in the accuracy of T-staging of AEG between TUS and CT (P > 0.05).
CONCLUSION TUS is an available tool for the typing of AEG, which is useful for deciding surgical approaches. TUS has high value in preoperative N- and M-staging, and for patients who are preoperatively diagnosed with poorly differentiated adenocarcinoma, both TUS and CT can be used in preoperative TNM-staging.

Abstract
Reflux is a common and tricky morbidity after gastrointestinal surgery which is caused by the destruction of physiological anti-reflux barriers, greatly affecting patients' postoperative quality of life. Gastroenterologists are now actively trying very hard to explore feasible, effective, and safe anti-reflux approaches. Conservative medical treatment, typically with proton pump inhibitors, is easily accepted by patients, however, its long-term adverse events are noteworthy. In the surgical aspect, laparoscopic anti-reflux surgery is gaining more and more popularity, after the first case of fundoplication. Besides, other operations, such as bariatric surgery, pediatric surgery, and pulmonary transplantation, are also frequently complicated by post-operative digestive reflux. Herein we systematically review the status quo and treatment modalities for post-surgical reflux disease, with the hope to facilitate surgeons to cope with this challenging issue appropriately.

Abstract
It has been previously reported that the deregulation of microRNAs in gastric cancer (GC) was correlated with the progression and prognosis. miR-429, a member of the miR-200 family, was previously shown to play an important role in human carcinomas. Our study shows that miR-429 is significantly downregulated in GC tissues compared with matched nontumor tissues. Overexpression of miR-429 in GC cells suppressed cell proliferation. Fascin-1 (FSCN1) was identified as one of the targets of miR-429 and knockdown of FSCN1 mimics the function of miR-429 overexpression. In conclusion, miR-429 acts as a tumor suppressor by targeting FSCN1, suggesting that miR-429 and FSCN1 can both be potential therapeutic targets of GC.

Abstract
Gastric cancer (GC) is one of the most common malignancies worldwide with poor prognosis for lack of early detection and effective treatment modalities. The significant influence of tumor microenvironment on malignant cells has been extensively investigated in this targeted-therapy era. Epithelial-mesenchymal transition (EMT) is a highly conserved and fundamental process that is critical for embryogenesis and some other pathophysiological processes, especially tumor genesis and progression. Aberrant gastric EMT activation could endow gastric epithelial cells with increased mesenchymal characteristics and less epithelial features, and promote cancer cell stemness, initiation, invasion, metastasis, and chemo-resistance with cellular adhesion molecules especially E-cadherin concomitantly repressed, which allows tumor cells to disseminate and spread throughout the body. Some pathogens, stress, and hypoxia could induce and aggravate GC via EMT, which is significantly correlated with prognosis. GC EMT is modulated by diverse micro-environmental, membrane, and intracellular cues, and could be triggered by various overexpressed transcription factors, which are downstream of several vital cross-talking signaling pathways including TGF-β, Wnt/β-catenin, Notch, etc. microRNAs also contribute significantly to GC EMT modulation. There are currently some agents which could suppress GC EMT, shedding light on novel anti-malignancy strategies. Investigating potential mechanisms modulating GC cell EMT and discovering novel EMT regulators will further elucidate GC biology, and may provide new biomarkers for early GC detection and potentially efficient targets for preventative and curative anti-GC intervention approaches to prevent local and distant invasions.

Abstract
Orai1 is one of the key components of store-operated Ca(2+) entry (SOCE) involved in diverse physiological functions. Orai1 may associate with other proteins to form a signaling complex. In the present study, we investigated the interaction between Orai1 and small conductance Ca(2+)-activated potassium channel 3 (SK3). With the use of RNA interference technique, we found that the SOCE and its associated membrane hyperpolarization were reduced while Orai1 was knocked down by a specific Orai1 siRNA in guinea pig gallbladder smooth muscle. However, with the use of isometric tension measurements, our results revealed that agonist-induced muscle contractility was significantly enhanced after Orai1 protein was knocked down or the tissue was treated by SK3 inhibitor apamin, but not affected by larger conductance Ca(2+)-activated potassium channel inhibitor iberiotoxin or intermediate conductance Ca(2+)-activated potassium channel inhibitor TRAM-34. In addition, in the presence of apamin, Orai1 siRNA had no additional effect on agonist-induced contraction. In coimmunoprecipitation experiment, SK3 and Orai1 pulled down each other. These data suggest that, Orai1 physically associated with SK3 to form a signaling complex in gallbladder smooth muscle. Ca(2+) entry via Orai1 activates SK3, resulting in membrane hyperpolarization in gallbladder smooth muscle. This hyperpolarizing effect of Orai1-SK3 coupling could serve to prevent excessive contraction of gallbladder smooth muscle in response to contractile agonists.

Abstract
The significant influence of tumor microenvironment on malignant cells has been investigated with enthusiasm in this era of targeted therapy. Transglutaminase 2 (TG2, EC 2.3.2.13), a multi-functional enzyme that catalyzes the formation of intermolecular isopeptide bonds between glutamine and lysine side-chains, has been reported to exert important pathophysiological functions. The aim of this review was to investigate the correlation between TG2 and malignant behaviors, which could provide the rationale for novel approaches in anti-cancer therapy. We performed a systematic and electronic search on Medline, Scopus, and Web of Science for relevant publications from inception to April 2015. The bibliographic references of retrieved articles were further reviewed for additional relevant studies. TG2 exerts important physiological functions and plays vital roles in inflammation mainly through its modulation on the structure and stability of extracellular matrix (ECM). It also regulates EMT of diverse malignant cells through various intracellular and extracellular pathways. TG2 also plays an important role in tumor progression and may serve as a novel prognostic biomarker and therapeutic target in various cancer types. TG2 promotes malignant cell mobility, invasion, and metastasis, and induces chemo-resistance of cancer cells, mainly through its pro-crosslink and signaling transduction mediation propensities. In conclusion, TG2 plays vital roles in malignancy progression, and may have important prognostic and therapeutic significances.

Abstract
Cardiovascular remodeling, as a hallmark of hypertension-induced pathophysiology, causes substantial cardiovascular morbidity and mortality. There is increasing evidence that has demonstrated a broad spectrum of pharmacological and therapeutic benefits of grape seed proanthocyanidins (GSP) against oxidative stress and cardiovascular diseases. In this study, 180- to 200-g SD rats treated with DOCA (120 mg/week sc with 1% NaCl and 0.2% KCl in drinking water) and GSP (150, 240, 384 mg/kg) or amlodipine (ALM) (5 mg/kg) for 4 weeks were recruited. The protective effects of GSP on blood pressure and cardiovascular remodeling in rats with DOCA-salt-induced hypertension were investigated. Our results indicated that DOCA-salt could induce hypertension, cardiovascular remodeling and dysfunction, oxidative stress and the release of endothelin-1 (ET-1) and could increase JNK1/2 and p38MAPK phosphorylation. GSP or ALM treatments significantly improved hypertension, cardiovascular remodeling and dysfunction and oxidative stress, restrained the release of ET-1 and down-regulated the JNK1/2 and p38MAPK phosphorylation. These findings demonstrate that GSP has protective effects against increase of blood pressure induced by DOCA-salt hypertension and cardiovascular remodeling by inhibiting the reactive oxygen species/mitogen-activated protein kinase pathway via restraining the release of ET-1.

Abstract
OBJECTIVES To investigate CD147 and matrix metalloproteinase-9 (MMP-9) expressions in type II/III adenocarcinoma of esophagogastric junction (AEG), and their clinicopathological significances. METHODS Seventy-four patients clinically and pathologically diagnosed with type II/III AEG were analyzed, each undergoing radical total gastrectomy and Roux-en-Y esophagojejunostomy. The avidin streptavidin-perosidase immunohistochemistry technique was used to detect CD147 and MMP-9 in type II/III AEGs and 20 para-tumor controls, and their correlations with clinicopathological data and their reciprocal relationship were then analyzed. Kaplan-Meier survival analysis was conducted to reveal their prognostic significances. SPSS 20.0 was used for data analysis. A difference was statistically significant with P < 0.05, and very significant with P < 0.01. RESULTS In type II/III AEG CD147 and MMP-9 were mainly expressed on cellular membrane of in tumor cell cytoplasm. MMP-9 expression was significantly stronger at tumor-stroma junction and front edge of invasion. Their positive rates were significantly higher in malignant tissues than para-tumor tissues (P < 0.01 for both). There existed a significant positive correlation between both expressions (P < 0.05). They were significantly more highly expressed in cancers with lymphatic metastasis (P < 0.01 for both), at TNM III/IV stages (P < 0.01 for both), and with poor differentiation grade (P < 0.05 for both). Higher CD147 and MMP-9 expression rates were correlated with inferior postsurgical survivals (P < 0.05 for both). CONCLUSIONS CD147 and MMP-9 could be novel biomarkers for type II/III AEG, and potentially predict tumor progression and prognosis. They are worth further investigation.

Abstract
The significant influence of tumor stroma on malignant cells has been extensively investigated in this era of targeted therapy. The tumor microenvironment, as a dynamic system, is orchestrated by various cells including tumor vascular composing cells, inflammatory cells and fibroblasts. As a major and important component in tumor stroma, increasing evidence has shown that spindle-shaped cancer-associated fibroblasts (CAFs) are a significant modifier of cancer evolution, and promote tumorigenesis, tumor invasion and metastasis by stimulating angiogenesis, malignant cell survival, epithelial-mesenchymal transition (EMT) and proliferation via direct cell-to-cell contact or secretion of soluble factors in most digestive solid tumors. CAFs are thought to be activated, characterized by the expression of α-smooth muscle actin, fibroblast activated protein, fibroblast specific protein, vimentin, fibronectin, etc. They are hypothesized to originate from normal or aged fibroblasts, bone marrow-derived mesenchymal cells, or vascular endothelial cells. EMT may also be an important process generating CAFs, and most probably, CAFs may originate from multiple cells. A close link exists between EMT, tumor stem cells, and chemo-resistance of tumor cells, which is largely orchestrated by CAFs. CAFs significantly induce immunosuppression, and may be a prognostic marker in various malignancies. Targeted therapy toward CAFs has displayed promising anticancer efficacy, which further reinforces the necessity to explore the relationship between CAFs and their hosts.

Abstract
AIM: To study whether female-specific prostheses are superior to conventional prostheses after total knee arthroplasty (TKA) by conducting this meta-analysis to evaluate the effects of the 2 different designs.
METHODS: A systematic electronic search was conducted in the databases of PubMed, EMBASE and the Cochrane Library for prospective and retrospective trials. Meta-analysis was performed for the outcomes, including range of motion (ROM), Knee Society score, Hospital for Special Surgery scores (HSS) and complications including deep infection, manipulation under anesthesia (MUA), revisions, anterior knee pain, deep vein thrombosis and overhang rate. Meta-analysis was conducted where applicable. Weighted mean difference (WMD) and odds ratio were calculated according to study type.
RESULTS: Seven studies including 1174 knees were eligible for data extraction and pooled analysis. The overhang rate of female-specific prostheses was significantly lower than the conventional ones (WMD, 3.25; 95%CI: 0.00-0.27; P = 0.001). ROM in the female-specific prostheses group after TKA tended to be greater than the conventional prostheses group; however, with insignificant difference (WMD, 2.48; 95%CI: -0.83-5.78; P = 0.14). HSS (WMD, 0.48; 95%CI: -1.45-0.88; P = 0.63) and complications including deep infection (WMD, 0.39; 95%CI: 0.19-3.08; P =0 .70), MUA (WMD, 1.53; 95%CI: 0.02-1.61; P = 0.13) and revisions (WMD, 0.55; 95%CI: 0.07-4.34; P = 0.13) were all comparable between the two groups with at least 1 year follow-up. Other indexes were revealed to be similar between the two treatments with a descriptive analytical method.
CONCLUSION: Although the overhang rate is lower with female-specific prostheses, the current evidence does not support that female-specific prostheses outweigh conventional ones after TKA.

Abstract
AIM: To investigate the necessity and correctness of acid suppression pre- and post-gastrectomy among gastric carcinoma (GC) patients.
METHODS: From June 2011 to April 2013, 99 patients who were diagnosed with GC or adenocarcinoma of the gastroesophageal junction (type II or III) and needed surgical management were enrolled. They all underwent gastrectomy by the same operators [35 undergoing total gastrectomy (TG) plus Roux-en-Y reconstruction, 34 distal gastrectomy (DG) plus Billroth I reconstruction, and 30 proximal gastrectomy (PG) plus gastroesophagostomy]. We collected and analyzed their gastrointestinal juice and tissues from the pre-operational day to the 5th day post-operation, and 6 mo post-surgery. Gastric pH was detected with a precise acidity meter. Gastric juice contents including potassium, sodium and bicarbonate ions, urea nitrogen, direct and indirect bilirubin, and bile acid were detected using Automatic Biochemical Analyzer. Data regarding tumor size, histological type, tumor penetration and tumor-node-metastasis (TNM) stage were obtained from the pathological records. Reflux symptoms pre- and 6 mo post-gastrectomy were evaluated by reflux disease questionnaire (RDQ) and gastroesophageal reflux disease questionnaire (GERD-Q). SPSS 16.0 was applied to analyze the data.
RESULTS: Before surgery, gastric pH was higher than the threshold of hypoacidity (4.25 ± 1.45 vs 3.5, P = 0.000), and significantly affected by age, tumor size and differentiation grade, and potassium and bicarbonate ions; advanced malignancies were accompanied with higher pH compared with early ones (4.49 ± 1.31 vs 3.66 ± 1.61, P = 0.008). After operation, gastric pH in all groups was of weak-acidity and significantly higher than that pre-gastrectomy; on days 3-5, comparisons of gastric pH were similar between the 3 groups. Six months later, gastric pH was comparable to that on days 3-5; older patients were accompanied with higher total bilirubin level, indicating more serious reflux (r = 0.238, P = 0.018); the TG and PG groups had higher RDQ (TG vs DG: 15.80 ± 5.06 vs 12.26 ± 2.14, P = 0.000; PG vs DG: 15.37 ± 3.49 vs 12.26 ± 2.14, P = 0.000) and GERD-Q scores (TG vs DG: 10.54 ± 3.16 vs 9.15 ± 2.27, P = 0.039; PG vs DG: 11.00 ± 2.07 vs 9.15 ± 2.27, P = 0.001) compared with the DG group; all gastric juice contents except potassium ion significantly rose; reflux symptom was significantly associated with patient’s body mass index, direct and indirect bilirubin, and total bile acid, while pH played no role.
CONCLUSION: Acidity is not an important factor causing unfitness among GC patients. There is no need to further alkalify gastrointestinal juice both pre- and post-gastrectomy.

Abstract
Gastric cancer (GC) is one of the most common and deadly malignancies nowadays, and inflammatory cells are closely related to tumor progression. This prospective study aims to uncover clinical significance of peripheral immune cells and build a treatment-predictive model. From July 2006 to July 2011, a total of 1131 GC patients were selected, with their general characteristics, peripheral blood and pathological parameters, and operational information obtained. The relevancies between preoperational neutrophil-lymphocyte ratio (NLR) and postsurgical pathological indexes were analyzed. SPSS 17.0 was applied in data analysis, comparing the differences of NLR between different groups using Mann-Whitney U test, contrasting the pathological differences between NLR elevated and reduced groups using Fisher test, and quantifying the correlation between post-surgical pathology and pre-operational NLR using univariate analysis. Patients were then classified into radical (applied in the training dataset) and non-radical gastrectomy (applied in the test dataset) groups, based on which we further tried to build a predictive model indicating appropriateness for radical resection using support vector machine (SVM). We found that: patients with tumor invading out of the myometrium (pT3-4) had significantly larger NLR than those with lesion limited within the myometrium (pT1-2) (P<0.05); poorly differentiated and undifferentiated malignancies were associated with higher NLR than well and moderately differentiated ones (P<0.05); there was larger NLR among patients with tumor length ≥4 cm than those <4 cm (P<0.01); preoperative NLR was significantly positively correlated with tumor TNM classification, number of metastatic lymph nodes, invasive depth and tumor size (P<0.05); larger proportion of elevated NLR was significantly associated with larger tumor size, later tumor and nodal stages, and higher TNM classification (P<0.01). We finally built a SVM model based on peripheral carcinoembryonic antigen, carbohydrate antigen 19-9, lymphocyte percentage and platelet count, effectively predicting the inappropriateness of patients undergoing curative gastrectomy when all the 4 parameters elevated with high accuracy (74.61% for the training dataset and 75.28% for the test dataset). We concluded that peripheral blood NLR indicated tumor progression, and that an efficient treatment-predictive SVM model was constructed.
