Impact of rifaximin on cirrhosis complications and gastric microbiota in patients with gastroesophageal variceal bleeding: A pilot randomized controlled trial.

Objectives: The application of rifaximin, a non-absorbable antibiotic, in hepatic encephalopathy (HE) has been well established; however, its effect on other complications in cirrhotic patients with previous gastroesophageal variceal bleeding (GEVB) remains unclear. Therefore, we performed a pilot randomized controlled trial aiming to evaluate the impact of rifaximin on cirrhosis-related complications and changes in gastric microbiota.

Methods: Eighty cirrhotic patients who received prophylactic endoscopic treatment for variceal rebleeding were randomly assigned to the control or rifaximin treatment group (rifaximin 400 mg twice daily for 8 weeks).

Topical Application of Methyl Nicotinate Solution Enhances Peripheral Blood Collection.

Objective: The purpose of this study was to investigate whether local application of methyl nicotinate solution can change the content and proportion of blood cells in peripheral blood samples and to determine whether this treatment is a safe and reliable method for improving peripheral blood collection.

Methods: Routine blood analysis and flow cytometry were used to analyze the contents and proportions of blood cells and T lymphocyte subsets in peripheral blood samples. Experimental blood specimens were collected from earlobes treated with different concentrations of methyl nicotinate solution, and the control group consisted of blood specimens collected from untreated earlobes.

Diagnostic Value of Tumor Markers in Peritoneal Lavage Fluid for Peritoneal Metastasis from Colorectal Cancer.

Objective: To investigate the diagnostic value of tumor markers in peritoneal lavage fluid in the diagnosis of peritoneal metastasis from colorectal cancer.

Methods: One hundred eighty-six patients with colorectal cancer and 15 patients with benign disease who underwent surgical treatment were included. The abdominal cavity and pelvis of the patients were lavaged with 200 ml of normal saline immediately after abdominal cavity incision or pneumoperitoneum establishment.

Increased portal vein diameter is predictive of portal vein thrombosis development in patients with liver cirrhosis.

Background: Cirrhotic patients with portal vein thrombosis (PVT) may have a high risk of hepatic decompensation and increased mortality. This study aimed to investigate if increased portal vein diameter is associated with PVT development.

Methods: A total of 174 cirrhotic patients were enrolled between February 1 and August 31, 2017.

Changes and significance of plasma fibrinogen gamma-chain concentration in preeclampsia patients.

Objective: To investigate the plasma fibrinogen gamma-chain concentration in preeclampsia patients and explore its value in preeclampsia prediction and auxiliary diagnosis.

Methods: Follow-up of pregnant women who regularly attended perinatal care at two hospitals in China was performed, and clinical data and plasma samples were collected at each examination until delivery. The gamma-chain concentration was detected by Western blotting, and Quantity One Software was used for gamma-chain grayscale value measurements.

Transfer learning radiomics based on multimodal ultrasound imaging for staging liver fibrosis.

Objectives: To propose a transfer learning (TL) radiomics model that efficiently combines the information from gray scale and elastogram ultrasound images for accurate liver fibrosis grading.

Methods: Totally 466 patients undergoing partial hepatectomy were enrolled, including 401 with chronic hepatitis B and 65 without fibrosis pathologically. All patients received elastography and got liver stiffness measurement (LSM) 2-3 days before surgery.

A Nude Mouse Model of Orthotopic Liver Transplantation of Human Hepatocellular Carcinoma HCCLM3 Cell Xenografts and the Use of Imaging to Evaluate Tumor Progression.

BACKGROUND This study aimed to develop a nude mouse model of orthotopic liver transplantation of HCCLM3 human hepatocellular carcinoma (HCC) cell xenografts and the use of imaging and histology to evaluate tumor development and progression. MATERIAL AND METHODS HCCLM3 cells were injected subcutaneously into 25 healthy male athymic BALB/c (nu/nu) nude mice. The tumors that developed were transplanted into the liver of a new set of nude mice.

Portal hypertension in hepatitis B-related cirrhosis: Diagnostic accuracy of liver and spleen stiffness by 2-D shear-wave elastography.

Aim: To assess the diagnostic accuracy of liver and spleen stiffness measured by 2-D shear-wave elastography (SWE) in evaluation of clinically significant and severe portal hypertension (CSPH and SPH, respectively).

Methods: Clinical data of 155 hepatitis B-related cirrhosis patients and their liver and spleen stiffness (L-SWE and S-SWE, respectively) were collected. The diagnostic performances of L-SWE, S-SWE, the liver stiffness-spleen diameter to platelet ratio score (LSPS) and portal hypertension risk score were evaluated.

Is Brachial Artery Blood Flow Measured by Sonography During Early Postoperative Periods Predictive of Arteriovenous Fistula Failure in Hemodialysis Patients?

Objectives: The aim of our study was to determine a brachial artery blood flow level measured by sonography during early postoperative periods that is predictive of arteriovenous fistula failure in hemodialysis patients.

Methods: Doppler sonography was used to estimate the blood flow in the brachial artery of 103 patients at 1 and 14 days after arteriovenous fistula creation. The performance of brachial artery blood flow during early postoperative periods for predicting fistula failure was evaluated, and optimal cutoff values were determined.

Hydrogen-rich saline attenuates postoperative liver failure after major hepatectomy in rats.

Background/aims: A major hepatectomy occasionally lead to acute liver failure and death. We demonstrated the anti-oxidative and anti-inflammatory effects and functional mechanisms of hydrogen-rich saline (HS), a novel antioxidant, on an experimental model of rats after a partial hepatectomy (PH).

Methods: The rats underwent a 90% hepatectomy.

In this paper, Shannong 87074-519, a derivative of wheat-decaploid Elytrigia elongata, was identified by inoculation assessment, cytological analysis, simple sequence repeat (SSR), molecular marker technique,and genomic in situ hybridization (GISH). The results are as follows: the chromosome number of Shannong87074-519 in root tip cells was 2n=44, 22 bivalents were observed in most PMC at MI, and the average chromosome configuration was 2n=44=21.82 II+0.

Comparative proteomic analysis between the invasive and commensal strains of Staphylococcus epidermidis.

Staphylococcus epidermidis is one of the major causative agents for nosocomial infections. To reveal the pathogenesis factors, we performed the comparative proteomic analysis of invasive ATCC35984 and commensal ATCC12228 strains by two-dimensional gel electrophoresis and matrix-assisted laser desorption/ionization-time of flight-mass spectrometry. The differentially expressed proteins were involved in carbohydrate metabolism, sugar binding, lipid degradation and amino acid binding.

Conserved genes in a path from commensalism to pathogenicity: comparative phylogenetic profiles of Staphylococcus epidermidis RP62A and ATCC12228.

Background: Staphylococcus epidermidis, long regarded as an innocuous commensal bacterium of the human skin, is the most frequent cause of nosocomial infections associated with implanted medical devices. This conditional pathogen provides a model of choice to study genome landmarks correlated with the transition between commensalism and pathogenicity. Traditional investigations stress differences in gene content.
