Circadian rhythm genes contribute to the prognosis prediction and potential therapeutic target in gastric cancer.

The role of circadian rhythm genes (CRGs) in gastric cancer (GC) is poorly understood. This study aimed to develop a CRG signature to improve understanding of prognosis and immunotherapy responses in GC patients. We integrated the The Cancer Genome Atlas-Stomach adenocarcinoma (TCGA-STAD) dataset with CRGs to develop a prognostic signature for GC.

Clinical Analysis of Sinistral Portal Hypertension.

Background: Sinistral portal hypertension (SPH) is the only type of portal hypertension that is entirely curable. However, it can easily cause varicose veins in the esophagus and/or stomach, as well as upper gastrointestinal hemorrhage. This study aimed to investigate the clinical characteristics and treatments of sinistral portal hypertension.

Thoracic ultrasound-guided real-time pleural biopsy in the diagnosis of pleural diseases: a systematic review and meta-analysis.

Background: Real-time thoracic ultrasound-guided pleural biopsy (TUSPB) is an important diagnostic method for pleural diseases. Traditional two-dimensional thoracic ultrasound, as well as newly developed contrast-enhanced ultrasound (CEUS) and ultrasound elastography (UE), are all used as guidance tools for pleural biopsies. Herein, we aimed to determine the diagnostic yield of real-time TUSPB for pleural diseases to better inform the decision-making process.

Relief of ovalbumin-induced airway remodeling by the glycyl-l-histidyl-l-lysine-Cu tripeptide complex via activation of SIRT1 in airway epithelial cells.

Fixed airflow limitation (FAO), prevalent in patients with severe or difficult-to-treat asthma, is mainly caused by airway remodeling. Airway remodeling is initiated by inflammation and involves subsequent pathological changes. Glycyl-l-histidyl-l-lysine (GHK) is a matrikine with anti-inflammatory and antioxidant effects, naturally existing in human tissue.

Predictive value of D-dimer and fibrinogen degradation product for splanchnic vein thrombosis in patients with severe acute pancreatitis: a single-center retrospective study.

Background And Aim: Early diagnosis of splanchnic vein thrombosis (SVT) after severe acute pancreatitis (SAP) remains difficult because of its insidious onset. Common serum markers for thrombosis such as D-dimer (D-D) have lost their diagnostic value due to their elevation in non-thrombotic patients with SAP. The aim of this study is to predict SVT after SAP using common serum indicators of thrombosis by establishing a new cut-off value.

Artificial intelligence empowers the second-observer strategy for colonoscopy: a randomized clinical trial.

Background: In colonoscopy screening for colorectal cancer, human vision limitations may lead to higher miss rate of lesions; artificial intelligence (AI) assistance has been demonstrated to improve polyp detection. However, there still lacks direct evidence to demonstrate whether AI is superior to trainees or experienced nurses as a second observer to increase adenoma detection during colonoscopy. In this study, we aimed to compare the effectiveness of assistance from AI and human observer during colonoscopy.

[Feasibility study on local infiltration anesthesia for postoperative analgesia in patients with hallux valgus].

Objective: To evaluate the clinical efficacy of local infiltration anesthesia of ropivacaine combined with compound betamethasone for postoperative analgesia in patients with hallux valgus.

Methods: From September 2019 to December 2020, 48 patients with hallux valgus were treated surgically. According to different postoperative analgesia methods, the patients were divided into combined local infiltration group and intravenous analgesia pump group.

Simulated atmospheric nitrogen deposition inhibited the leaf litter decomposition of Cinnamomum migao H. W. Li in Southwest China.

Atmospheric nitrogen (N) deposition could affect various ecological processes in forest ecosystems, including plant litter decomposition and nutrient cycling. However, the mechanism of underlying litter decomposition and nutrient cycling of Cinnamomum migao under N deposition remains unclear. Therefore, we conducted a simulated N deposition experiment including four onsite treatments to assess the effects of N input on C.

Inhibition of FEN1 Increases Arsenic Trioxide-Induced ROS Accumulation and Cell Death: Novel Therapeutic Potential for Triple Negative Breast Cancer.

Triple-negative breast cancer (TNBC) is an aggressive subtype of breast cancer, which is very difficult to treat and commonly develops resistance to chemotherapy. The following study investigated whether the inhibition of Flap Endonuclease 1 (FEN1) expression, the key enzyme in the base excision repair (BER) pathway, could improve the anti-tumor effect of arsenic trioxide (ATO), which is a reactive oxygen species (ROS) inducer. Our data showed that ATO could increase the expression of FEN1, and the knockdown of FEN1 could significantly enhance the sensitivity of TNBC cells to ATO both and .

Survey of nocturnal reflux in patients with gastroesophageal reflux disease in China.

Unlabelled: To evaluate current diagnosis and treatment of patients with nocturnal gastroesophageal reflux (nGER).

Methods: This multicenter observational study was conducted in 44 hospitals in China from May 2017 to February 2018. Outpatients with nGER were recruited and their relevant data were collected using a questionnaire, including age, gender, body mass index, history of smoking and alcohol consumption, comorbid diseases, lifestyle, self-reported health status, medical history, nGER symptoms and severity, Hospital Anxiety Depression Scale, Pittsburgh Sleep Quality Index, diagnosis and treatment choices.

Hookworm Infection: A Neglected Cause of Overt Obscure Gastrointestinal Bleeding.

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas.

Effects of antithrombotic therapy on bleeding after endoscopic submucosal dissection.

Background And Aims: Bleeding is the most common adverse event after endoscopic submucosal dissection (ESD). Although several studies have reported on the use of antithrombotic agents and post-ESD bleeding, many issues remain controversial. We conducted a meta-analysis and systematic review to evaluate the effects of antithrombotic therapy on post-ESD bleeding.

The Role of CagA in Regulating Hormones of Functional Dyspepsia Patients.

(, Hp) colonizes the stomachs of approximately 20%-80% of humans throughout the world. The Word Healthy Organization (WHO) classified as a group 1 carcinogenic factor in 1994. Recently, an increasing number of studies has shown an association between infection and various extragastric diseases.

miR-485-5p acts as a negative regulator in gastric cancer progression by targeting flotillin-1.

MicroRNAs (miRNAs) play important roles in cancer progression including gastric cancer. miR-485-5p is reported as a potential suppressor in breast cancer, but its expression, cellular function and clinic features in gastric cancer is not known. In our study, we found that miR-485-5p expression was down-regulated in gastric cancer cell lines.

Adipose-derived stem cells: A candidate for liver regeneration.

The scarcity of donor livers and the impracticality of hepatocyte transplantation represent the biggest obstacles for the treatment of liver failure. Adipose-derived stem cells, with their ability to differentiate into the hepatic lineage, provide a reliable alternative cell source with clear ethical and practical advantages. Moreover, adipose-derived stem cells can effectively repair liver damage by the dominant indirect pattern and increase the number of hepatocytes by the secondary direct pattern.

Life table evaluation of survival and reproduction of the aphid, Sitobion avenae, exposed to cadmium.

The effects of cadmium (Cd) on the development, fecundity, and reproduction of the grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae) were estimated by constructing a life table of S. avenae exposed to Cd. The concentrations of Cd in the soil were as follows: 0, 10, 20, 40, 80, and 160 mg/kg.
