Development and validation of serological dynamic risk score to predict outcome in gastric cancer with adjuvant chemotherapy: a multicentre, longitudinal, cohort study.

Background: Baseline serological biomarkers have the potential to predict the benefits of adjuvant chemotherapy in patients with gastric cancer. However, the fluctuating nature of postoperative recurrence risk makes precise treatment challenging. We aimed to develop a risk score in real-time predicting outcomes for postoperative GC patients using blood chemistry tests.

Development and validation of a prognostic score to identify the optimal candidate for preemptive TIPS in patients with cirrhosis and acute variceal bleeding.

Background And Aim: Baveno VII workshop recommends the use of preemptive TIPS (p-TIPS) in patients with cirrhosis and acute variceal bleeding (AVB) at high- risk of treatment failure. However, the criteria defining "high-risk" have low clinical accessibility or include subjective variables. We aimed to develop and externally validate a model for better identification of p-TIPS candidates.

Association of nonmalignant portal vein thrombosis and clinical outcomes in patients with cirrhosis and acute variceal bleeding: a multicenter observational study.

Background And Aim: Baveno VII workshop recommends management of acute variceal bleeding (AVB) in cirrhotic patients with nonmalignant portal vein thrombosis (PVT) should be performed according to the guidelines for patients without PVT. Nevertheless, whether PVT affects the outcome of patients with cirrhosis and AVB remains unclear. The aim of this study was to assess the clinical impact of PVT on the outcomes in the pre-emptive TIPSS eligible patients with cirrhosis and AVB.

Risk stratification in patients with upper gastrointestinal submucosal tumors undergoing submucosal tunnel endoscopic resection.

Background: A substantial heterogeneity exists in patients with upper gastrointestinal submucosal tumors (SMTs). This study aimed to identify predictors of long procedure time (≥60 min), occurrence of procedure-related complications, and long hospital stay (≥6 days) in patients with SMTs undergoing submucosal tunnel endoscopic resection (STER) and stratify risk based on the predictors.

Methods: Sixty-six consecutive patients with upper gastrointestinal SMTs undergoing STER between January 2013 and December 2018 were retrospectively included.

Emergency Removal of Ingested Foreign Bodies in 586 Adults at a Single Hospital in China According to the European Society of Gastrointestinal Endoscopy (ESGE) Recommendations: A 10-Year Retrospective Study.

BACKGROUND The 2016 European Society of Gastrointestinal Endoscopy (ESGE) guidelines recommend that ingested foreign bodies in the upper gastrointestinal (GI) tract are removed as an emergency within 6 hours, with an endoscopic approach that is individualized according to the type of foreign body identified. This retrospective study evaluated the 10-year experience of a single hospital in China performing emergency removal of ingested foreign bodies in 586 adults. MATERIAL AND METHODS Between 2011 and 2020, medical records of 642 adults with a diagnosis of foreign bodies ingestion were retrospectively screened.

Abnormal Liver Function Tests Were Associated With Adverse Clinical Outcomes: An Observational Cohort Study of 2,912 Patients With COVID-19.

The impact of liver function test (LFTs) abnormality on adverse clinical outcomes in coronavirus disease 2019 (COVID-19) patients remains controversial. The aim of this study was to assess the impact of abnormal LFTs on clinical outcomes in a large cohort of hospitalized patients with COVID-19. We retrospectively collected data on 2,912 consecutive patients with COVID-19 who were admitted to a makeshift hospital in China between 5 February and 23 March 2020.

Association of systemic inflammation and body mass index with survival in patients with resectable gastric or gastroesophageal junction adenocarcinomas.

Objective: The systemic inflammation index and body mass index (BMI) are easily accessible markers that can predict mortality. However, the prognostic value of the combined use of these two markers remains unclear. The goal of this study was therefore to evaluate the association of these markers with outcomes based on a large cohort of patients with gastric cancer.

KRAS Mutation-Responsive miR-139-5p inhibits Colorectal Cancer Progression and is repressed by Wnt Signaling.

Colorectal cancer (CRC) frequently harbors KRAS mutations that result in chemoresistance and metastasis. MicroRNAs (miRNAs) are usually dysregulated and play important regulatory roles in tumor progression. However, the KRAS mutation-responsive miRNA profile in CRC remains uninvestigated.

Efficacy and Safety of Multiband Mucosectomy Versus Cap-assisted Endoscopic Resection For Early Esophageal Cancer and Precancerous Lesions: A Systematic Review and Meta-Analysis.

Background: The effectiveness of multiband mucosectomy (MBM) for early esophageal cancer and precancerous lesions is still in uncertainty. We aimed to evaluate the efficacy and safety of this procedure and to compare it with cap-assisted endoscopic resection (EMR-cap).

Methods: A systematic search of both English and Chinese databases was performed from inception to April 30, 2019.

Knockdown of cyclooxygenase-2 leads to growth inhibition and cell cycle arrest in hepatocellular carcinoma cells.

Cyclooxygenase-2 (COX-2) is proved to play important roles in the development and progression of various human tumors, including hepatocellular carcinoma (HCC). However, the antitumor effect of RNA interference (RNAi) technology targeting COX-2 in HCC has not yet been verified. We silenced COX-2 expression using a lentivirus-mediated RNAi and further investigated the effects of COX-2 knockdown on cell growth and cell cycle in Huh7 and SMMC-7721 cells.

Early TIPS with covered stents versus standard treatment for acute variceal bleeding in patients with advanced cirrhosis: a randomised controlled trial.

Background: The survival benefit of early placement of transjugular intrahepatic portosystemic shunts (TIPS) in patients with cirrhosis and acute variceal bleeding is controversial. We aimed to assess whether early TIPS improves survival in patients with advanced cirrhosis and acute variceal bleeding.

Methods: We did an investigator-initiated, open-label, randomised controlled trial at an academic hospital in China.

TIPSS for variceal bleeding in patients with idiopathic non-cirrhotic portal hypertension: comparison with patients who have cirrhosis.

Background: In patients with idiopathic non-cirrhotic portal hypertension (INCPH), the usual recommended strategy for management of variceal bleeding is the same as that in cirrhosis. However, this policy has been challenged by the different natural history between INCPH and cirrhosis.

Aim: To compare outcomes after transjugular intrahepatic portosystemic shunt (TIPSS) between INCPH and cirrhotic patients admitted for variceal bleeding.

[Overexpression of miR-107 promotes the proliferation and tumorigenic ability of HT29 cells].

Objective To investigate the effect of miR-107 on the proliferation of colorectal cancer cells. Methods The expression of miR-107 was detected in colorectal cancer tissues and colorectal cancer cell lines by real-time quantitative PCR (qRT-PCR). miR-107 expression was up-regulated and down-regulated by the transfection of miR-107 mimic and miR-107 inhibitor in HT29 cells, respectively.

Overexpression of serum response factor is correlated with poor prognosis in patients with gastric cancer.

Serum response factor (SRF) is highly expressed in many tumors, including gastric cancer. However, the exact prognostic utility of SRF in patients with gastric cancer remains unclear. Therefore, in this study, we investigated the expression and prognostic value of SRF in patients with gastric cancer.

FOXM1 promotes proliferation in human hepatocellular carcinoma cells by transcriptional activation of CCNB1.

The transcription factor Forkhead box protein M1 (FOXM1) plays critical roles in cancer development and progression, including human hepatocellular carcinoma (HCC). However, the regulatory role and underlying mechanisms of FOXM1 is still limited. Here, we found that the high level expression of FOXM1 and CCNB1 is closely associated with poor prognosis in HCC patients.

Covered TIPS versus endoscopic band ligation plus propranolol for the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis: a randomised controlled trial.

Objective: Limited data are available on the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis (PVT). This study aimed to compare transjugular intrahepatic portosystemic shunt (TIPS) with covered stents versus endoscopic band ligation (EBL) plus propranolol for the prevention of variceal rebleeding among patients with cirrhosis and PVT.

Design: Consecutive cirrhotic patients (94% Child-Pugh class A or B) with PVT who had variceal bleeding in the past 6 weeks were randomly assigned to TIPS group (n=24) or EBL plus propranolol group (EBL+drug, n=25), respectively.

Peroral endoscopic myotomy for the treatment of achalasia in a patient with esophageal varices. A case report.

Achalasia is very uncommon, and rarely does achalasia co-exist with esophageal varices. We present a 62-year-old woman who was diagnosed with both achalasia and esophageal varices in December 2014 and had a past history of hematemesis. The patient's achalasia symptoms' Eckardt score was 9, and her hepatic function was Child-Pugh grade A6.

Eight millimetre covered TIPS does not compromise shunt function but reduces hepatic encephalopathy in preventing variceal rebleeding.

Background & Aims: Currently, there are no recommendations in guidelines concerning the preferred diameter of stents for transjugular intrahepatic portosystemic shunt (TIPS), owing to the lack of adequate evidence. We therefore compared 8mm stents with 10mm stents, to evaluate whether 8mm stents would achieve similar shunt function, with less hepatic encephalopathy (HE) and better liver function.

Methods: Cirrhotic patients were randomly assigned to receive TIPS with an 8mm or 10mm covered stent to prevent variceal rebleeding.

[Increased expression URG11 in hepatocellular carcinoma tissues promotes the growth of hepatocellular carcinoma cells].

Objective: To detect the expression of upregulated gene 11 (URG11) in hepatocellular carcinoma (HCC) tissues and cell lines and study the effect of URG11 on HCC cell growth.

Methods: URG11 expression was detected through immunohistochemistry in normal liver tissues, HCC tissues, and matched adjacent non-cancer tissues. URG11 expression in HCC cell lines and control liver cell line was examined by reverse transcription PCR and western blotting.

MicroRNA-7/NF-κB signaling regulatory feedback circuit regulates gastric carcinogenesis.

MicroRNAs play essential roles in gene expression regulation during carcinogenesis. Here, we investigated the role of miR-7 and the mechanism by which it is dysregulated in gastric cancer (GC). We used genome-wide screenings and identified RELA and FOS as novel targets of miR-7.
