Multiple Omics Integration Reveals Key Circular RNAs in Hepatocellular Carcinoma.

Background: HCC is one of the most common malignancies with an increasing incidence worldwide, especially in Asian countries. However, even though targeted cancer therapy drugs such as sorafenib and regorafenib are available, the overall outcome of HCC remains unsatisfactory. Thus, it is urgent to investigate the molecular mechanisms of HCC progression, so as to provide accurate diagnostic criteria and therapeutic targets.

Effects of viral infection and microbial diversity on patients with sepsis: A retrospective study based on metagenomic next-generation sequencing.

Background: The study aims to investigate the performance of a metagenomic next-generation sequencing (NGS)-based diagnostic technique for the identification of potential bacterial and viral infections and effects of concomitant viral infection on the survival rate of intensive care unit (ICU) sepsis patients.

Methods: A total of 74 ICU patients with sepsis who were admitted to our institution from February 1, 2018 to June 30, 2019 were enrolled. Separate blood samples were collected from patients for blood cultures and metagenomic NGS when the patients' body temperature was higher than 38 °C.

Exosomal circRNA-100338 promotes hepatocellular carcinoma metastasis via enhancing invasiveness and angiogenesis.

Background: Exosomes play crucial roles in regulating the crosstalk between normal and cancer cells in the tumor microenvironment, and in regulating cancer proliferation, migration and invasion through their cargo molecules.

Methods: We analyzed the pro-invasiveness of exosomal circRNA-100,338 in HCC using the transwell invasion assay. The co-culture of human umbilical vein endothelial cells (HUVEC) and exosomes derived from HCC cell lines were used to evaluate the impact of HCC derived exosomes on HUVEC.

Recombinant adenovirus p53 combined with radiotherapy improves efficacy and safety in the treatment of head and neck lymphoma.

Objective: Lymphoma is considered to be a kind of malignant tumour. Gene therapy and radiotherapy have been reported as treatment methods for head and neck lymphoma. This study aims to evaluate the efficacy and safety for the treatment of head and neck lymphoma by a combination of recombinant adenovirus p53 (rAd-p53) and radiotherapy.

Efficacy, Efficiency, and Safety of Magnetic Resonance-Guided High-Intensity Focused Ultrasound for Ablation of Uterine Fibroids: Comparison with Ultrasound-Guided Method.

Objective: The purpose of this study was to compare efficacy, sonication energy efficiency, treatment time and safety of magnetic resonance-guided high-intensity focused ultrasound (MRgHIFU) and those of ultrasound-guided high-intensity focused ultrasound (USgHIFU) for ablation of uterine fibroids.

Materials And Methods: This study included 43 patients with 44 symptomatic uterine fibroids treated with MRgHIFU and 51 patients with 68 symptomatic uterine fibroids treated with USgHIFU. After therapy, contrast-enhanced MRI was conducted and complete ablation was defined as 100% non-perfused volume (NPV) of fibroids.

Missing-in-metastasis B (MIM-B) combined with caveolin-1 promotes metastasis of hepatocellular carcinoma.

Background: Increasing amounts of evidence indicate that Missing in metastasis B (MIM-B) promotes cancer metastasis. Here, we sought to better understand the mechanism through which MIM-B promotes tumor metastasis in hepatocellular carcinoma (HCC).

Methods: We performed confocal microscopy analysis to determine the distributions of MIM-B and caveolin-1 and conducted co-immunoprecipitation assays to detect the interactions between MIM-B and caveolin-1 .

Three modalities on common bile duct exploration.

 Choledocholithiasis can be managed by transcystic (TC) and transduct (TD) stone extraction or using cholangioscopy through the left hepatic duct orifice (LHD).  The aim of this study is to evaluate the safety and effectiveness of common bile duct exploration through the TC approach, TD approach, and LHD approach for choledocholithiasis, with a specific emphasis on the TC and LHD approaches versus the TD approach.  Between January 2011 and June 2014, a total of 172 choledocholithiasis patients accompanied by cholecystitis and/or left intrahepatic gallstones were scheduled for laparoscopic or open common bile duct (CBD) exploration using cholangioscopy through the CBD (TD group: n = 72), cystic duct (TC group: n = 63), or LHD orifice (LHD group: n = 37).

Comprehensive circular RNA profiling reveals the regulatory role of the circRNA-100338/miR-141-3p pathway in hepatitis B-related hepatocellular carcinoma.

Circular RNAs (circRNAs) represent a class of endogenous noncoding RNAs that have recently been recognized as important regulators of gene expression and pathological networks. However, their transcriptional activities and functional mechanisms in cancer remain largely unknown. Here, we present results from a global circRNA expression and functional analysis of patients with hepatocellular carcinoma (HCC).

Pancreatic cancer cell-derived IGFBP-3 contributes to muscle wasting.

Background: Progressive loss of skeletal muscle, termed muscle wasting, is a hallmark of cancer cachexia and contributes to weakness, reduced quality of life, as well as poor response to therapy. Previous studies have indicated that systemic host inflammatory response regarding tumor development results in muscle wasting. However, how tumor directly regulates muscle wasting via tumor-derived secreted proteins is still largely unknown.

[Research of chemotaxis response of Botrytis cinerea and Alternaria panax on total ginsenosides].

In this paper, three kinds of chemotactic parameters (concentration, temperature and pH) were determined by plate assay and spore germination method to research the chemotactic response of Botrytis cinerea and Alternaria panax, and their spores on total ginsenosides. The results showed that Botrytis cinerea had strong chemotactic response at the mid-concentration of total ginsenosides (cultivation temperature was 20 degrees C and pH value was 6), and the data of chemotactic migration index (CMI) was 1.293 0, chemotactic growth rate (CGR) was 0.

[Anti-feeding activity of total ginsenoside from Panax ginseng to 4th-instar Mythimna separata larvae].

This paper is in order to study the anti-feeding and growth inhibition activity of toatal ginsenoside of ginseng stems and leaves against 4th-instar Mythimna separata larvae. Simulating natural growing condition indoors, on the base, To study the anti-feeding and growth inhibition activity of toatal ginsenoside against 4th-instar M. separata larvae by leaf disc test.

[Establishment of a high metastatic potential human hepatocellular carcinoma orthotopic transplantation model with palliative liver resection in nude mice].

Objective: To construct a high metastatic potential human hepatocellular carcinoma (HCC) orthotopic transplantation model with palliative liver resection in nude mice.

Methods: A human HCC orthotopic nude mice model was established by administering a single inoculation of the highly metastatic MHCC97H tumor tissue (size 2 mm * 2 mm * 2 mm) into the left liver lobe. At day 14 post-inoculation, a random group of the mice received palliative liver resection; the unresected mice served as controls.
