Network pharmacology and molecular docking elucidate potential mechanisms of Eucommia ulmoides in hepatic ischemia-reperfusion injury.

Eucommia ulmoides (EU) and its diverse extracts have demonstrated antioxidative, anti-inflammatory, and cytoprotective properties against hepatic ischemia-reperfusion injury (HIRI). However, the primary constituents of EU and their putative mechanisms remain elusive. This study aims to explore the potential mechanisms of EU in the prevention and treatment of HIRI by employing network pharmacology and molecular docking methodologies.

Mitochondrial quality control in hepatic ischemia-reperfusion injury.

Hepatic ischemia-reperfusion injury is a phenomenon in which exacerbating damage of liver cells due to restoration of blood flow following ischemia during liver surgery, especially those involving liver transplantation. Mitochondria, the energy-producing organelles, are crucial for cell survival and apoptosis and have evolved a range of quality control mechanisms to maintain homeostasis in the mitochondrial network in response to various stress conditions. Hepatic ischemia-reperfusion leads to disruption of mitochondrial quality control mechanisms, as evidenced by reduced mitochondrial autophagy, excessive division, reduced fusion, and inhibition of biogenesis.

Chlorogenic Acid Alleviates Hepatic Ischemia-Reperfusion Injury by Inhibiting Oxidative Stress, Inflammation, and Mitochondria-Mediated Apoptosis In Vivo and In Vitro.

Hepatic ischemia-reperfusion injury (HIRI) is the main reason for organ failure following liver surgery; however, its underlying causes are complex, and include oxidative stress, sterile inflammatory, and mitochondrial damage. Unfortunately, treatments for HIRI are based on supportive therapy, and no specific drugs or methods are currently available. Chlorogenic acid (CGA) is a dietary polyphenol with a wide range of pharmacological effects and it has a protective effect on HIRI; however, its specific mechanism remains unclear.

Single-Cell Sequencing of Hepatocellular Carcinoma Reveals Cell Interactions and Cell Heterogeneity in the Microenvironment.

Background: Hepatocellular carcinoma (HCC) is the main histological subtype of liver cancer, which has the characteristics of poor prognosis and high fatality rate. Single-cell sequencing can provide quantitative and unbiased characterization of cell heterogeneity by analyzing the molecular profile of the whole genome of thousands of single cells. Thus, the purpose of this study was to identify novel prognostic markers for HCC based on single-cell sequencing data.

Aucubin Attenuates Liver Ischemia-Reperfusion Injury by Inhibiting the HMGB1/TLR-4/NF-κB Signaling Pathway, Oxidative Stress, and Apoptosis.

Liver ischemia-reperfusion injury (IRI) is a common clinical event with high morbidity in patients undergoing complex liver surgery or having abdominal trauma. Inflammatory and oxidative stress responses are the main contributing factors in liver IRI. The iridoid glucoside aucubin (AU) has good anti-inflammatory and antioxidative effects; however, there are no relevant reports on the protective effect of glucosides on hepatic IRI.

Anti-Inflammatory and Antioxidant Effect of Polysaccharide in Hepatic Ischemia-Reperfusion Injury by Regulating ROS and the TLR-4-NF-B Pathway.

polysaccharide (EUP) has been shown to have anti-inflammatory and antioxidant effects. However, the mechanism underlying these effects has rarely been reported, and whether EUP can reduce liver injury in hepatic ischemia-reperfusion injury (HIRI) has not been reported. In this study, 40 Sprague-Dawley (SD) rats were randomly divided into 5 groups: the sham group, ischemia-reperfusion (I/R) group, and three EUP pretreatment groups (320 mg/kg, 160 mg/kg, and 80 mg/kg).

LncRNA CRNDE promotes hepatocellular carcinoma progression by upregulating SIX1 through modulating miR-337-3p.

Background: Long noncoding RNA (lncRNA) is emerging as a vital regulator in various cancers. Recently, it was found that lncRNA colorectal neoplasia differentially expressed (CRNDE) plays an oncogenic role, promoting cell proliferation and migration in hepatocellular carcinoma (HCC). However, the underlying regulatory mechanism of lncRNA CRNDE remains unclear.

Combination of serum gamma-glutamyltransferase and alkaline phosphatase in predicting the diagnosis of asymptomatic choledocholithiasis secondary to cholecystolithiasis.

Background: Gamma-glutamyltransferase (GGT) is one of the most important laboratory tests for the evaluation of liver damage. Through a long-term clinical observation of patients with secondary asymptomatic choledocholithiasis, we found that most patients had abnormal GGT serum levels.

Aim: To investigate the combination of serum GGT and alkaline phosphatase (ALP) in predicting the diagnosis of asymptomatic choledocholithiasis secondary to cholecystolithiasis.

Diagnostic value of elevated serum carbohydrate antigen 199 level in acute cholangitis secondary to choledocholithiasis.

Aim: To investigate the diagnostic value of abnormal serum carbohydrate antigen 199 (CA199) level in acute cholangitis secondary to choledocholithiasis.

Methods: In this retrospective cohort study, the clinical data of 727 patients with choledocholithiasis admitted to the Third Affiliated Hospital of Zunyi Medical College from June 2011 to June 2017 were collected. Among these patients, 258 patients had secondary acute cholangitis and served as observation group, and the remaining 569 choledocholithiasis patients served as the control group.

Predictive value of drain pancreatic amylase concentration for postoperative pancreatic fistula on postoperative day 1 after pancreatic resection: An updated meta-analysis.

Background: Postoperative pancreatic fistula (POPF) is a potentially fatal complication following pancreaticoduodenectomy. Early prediction and exclusion of POPF may be highly advantageous to enhance patient outcomes, and accelerate recovery. In this meta-analysis, we sought to assess the prediction of drain pancreatic amylase concentration on postoperative day 1 (DPA1) for POPF.

The Decrease of Peripheral Blood CD4+ T Cells Indicates Abdominal Compartment Syndrome in Severe Acute Pancreatitis.

Objective: Few data are available on the role of T lymphocytes and inflammatory cytokines in abdominal compartment syndrome (ACS) in severe acute pancreatitis (SAP). We conducted a retrospective study to assess the risk factors associated with ACS in SAP.

Methods: A total of 76 SAP patients who were admitted within 24 hours after symptom onset in our study.

Simultaneous Occurrence of a Rare Pancreatic Lymphoepithelial Cyst and Duodenal Mesenteric Castleman's Disease: a Case Report.

Pancreatic lymphoepithelial cyst is a rare pancreatic lesion of undetermined pathogenesis, which is a true pancreatic cyst. Castleman's disease is a rare lymphoproliferative disorder, and a mesenteric location is unusual. The simultaneous occurrence of the two diseases are rarer than metachronous ones and has not been reported to date.

Hemolymphangioma of the spleen: A report of a rare case.

Hemolymphangioma is a malformation of both lymphatic vessels and blood vessels. Splenic hemolymphangioma is extremely rare. Herein, we present a case of 62-year-old woman with ambiguous upper quadrant abdominal pain for two months who was found to have an occupying lesion in the spleen on computed tomography.

Efficacy of middle hepatic vein reconstruction in adult right-lobe living donor liver transplantation.

Background: Congestion of the right anterior segment may lead to graft dysfunction in right-lobe living donor liver transplantation (LDLT) without a middle hepatic vein (MHV) trunk. Selective reconstruction of MHV tributaries with the interposition of vascular grafts has been introduced to overcome this problem. However, there is still no consensus on the definite criteria of MHV reconstruction.

Objective: To analyze risk factors of marginal donors in living donor liver transplantation.

Methods: 98 living donor liver transplantation (LDLT) patients over the 7-year period from 2001 to 2007 in our transplantation center were retrospected. Potential risk factors, including donor age, gender-mismatch, steatotic donors and graft-recipient weight ratio (GRWR), and their relationship with 6-month patient survival rate were analyzed.
