Neglected errors in ligament reconstruction surgery may increase graft-tunnel mismatch: A biomechanical study.

Tunnel widening is a frequent problem following arthroscopic ligament reconstruction surgery that may primarily arise from a graft-tunnel mismatch caused by errors in surgical instruments and methods. The present study aimed to observe the influence of current surgical instruments and methods on graft-tunnel matching. We established an in vitro model using porcine Achilles tendons and tibias, and compared traditional surgical instruments (control group) with custom instruments (experimental group).

CBLC promotes the development of colorectal cancer by promoting ABI1 degradation to activate the ERK signaling pathway.

CBLC (CBL proto-oncogene C) is an E3 ubiquitin protein ligase that plays a key role in cancers. However, the function and mechanism of CBLC in colorectal cancer (CRC) has not been fully elucidated. The aim of this study was to investigate the function of CBLC in CRC and its underlying molecular mechanism.

Clopidogrel Plus Aspirin vs Aspirin Alone in Patients With Acute Mild to Moderate Stroke: The ATAMIS Randomized Clinical Trial.

Objective: To evaluate whether dual antiplatelet therapy is superior to single antiplatelet among patients with mild to moderate ischemic stroke.

Design, Setting, And Participants: This was a multicenter, open-label, blinded end point, randomized clinical trial conducted at 66 hospitals in China from December 20, 2016, through August 9, 2022.

Tenecteplase Plus Butyphthalide for Stroke Within 4.5-6 Hours of Onset (EXIT-BT): a Phase 2 Study.

To date, the benefit of intravenous thrombolysis is confined to within 4.5 h of onset for acute ischemic stroke (AIS) without advanced neuroimaging selection. The current trial aimed to investigate the safety and efficacy of intravenous tenecteplase (TNK) plus Dl-3-n-Butylphthalide (NBP) in AIS within 4.

Background: CMTM6 which is chemokine-like factor (CKLF)-like Marvel transmembrane domain containing family member 6 is involved in the occurrence and progression of various tumors. However, the role of CMTM6 is still unclear in lung adenocarcinoma (LUAD).

Methods: Immunohistochemical, Western blotting and RT‒PCR methods were used to detect the expression of CMTM6 in LUAD.

Association of uric acid levels with cardiac syndrome X: A meta-analysis.

The pathogenesis of elevated uric acid (UA) levels in patients with cardiac syndrome X (CSX) is unclear, and the results presented in recent papers on UA levels in patients with CSX are controversial. Therefore, we conducted a meta- analysis to assess the relationship between UA levels and CSX. Three databases, including the Web of Science, EMBASE and PubMed, were systematically searched until January 2022.

Inhibition of miRNA-1-Mediated Inflammation and Autophagy by Astragaloside IV Improves Lipopolysaccharide-Induced Cardiac Dysfunction in Rats.

Introduction: Astragaloside IV (AS-IV) is one of the main active components isolated from the traditional Chinese medicinal herb, . The present study was designed to investigate whether the regulation of microRNA-1 (miR-1)-mediated inflammation and autophagy contributes to the protective effect of AS-IV against cardiac dysfunction in rats treated with lipopolysaccharides (LPS).

Methods: Animal model of cardiac dysfunction in rats or cellular model of injured H9c2 heart cell line was established by using LPS.

Protective effect of hydrogen sulfide on the kidney (Review).

Hydrogen sulfide (HS) is a physiologically important gas transmitter that serves various biological functions in the body, in a manner similar to that of carbon monoxide and nitric oxide. Cystathionine‑β‑synthase, cystathionine‑γ‑lyase and cysteine transaminase/3‑mercaptopyruvate sulphotransferase are important enzymes involved HS production , and the mitochondria are the primary sites of metabolism. It has been reported that HS serves an important physiological role in the kidney.

8-Hydroxyquinolin-2(1H)-one analogues as potential β-agonists: Design, synthesis and activity study.

β-Agonists that bind to plasmalemmal β-adrenoceptors causing cAMP accumulation are widely used as bronchodilators in chronic respiratory diseases. Here, we designed and synthesized a group of 8-hydroxyquinolin-2(1H)-one analogues and studied their β-agonistic activities with a cellular cAMP assay. Compounds B05 and C08 were identified as potent (EC < 20 pM) and selective β-agonists among the compounds tested.

Astragaloside IV-targeting miRNA-1 attenuates lipopolysaccharide-induced cardiac dysfunction in rats through inhibition of apoptosis and autophagy.

Astragaloside IV (AS-IV), the major active constituent purified from Astragalus membranaceus, was previously reported to have protective effects against cardiac dysfunction. However, the underlying mechanism remains unknown. In the present study, we investigated the protective effect of AS-IV on lipopolysaccharide (LPS)-induced cardiac dysfunction and explored the potential mechanism by focusing on miRNA-1 (miR-1) at the animal and cellular levels.

Nuclear heme oxygenase-1 improved the hypoxia-mediated dysfunction of blood-spinal cord barrier via the miR-181c-5p/SOX5 signaling pathway.

Our previous study demonstrated that adenovirus-delivered GFP nuclear heme oxygenase-1 (nuclear HO-1, NHO-1) fragments lacking 23 amino acids at the C-terminus (Ad-GFP-HO-1C[INCREMENT]23) showed the potential therapeutic effects mediated by its improvement of the blood-spinal cord barrier (BSCB) integrity. However, the NHO-1-mediated molecular mechanism in regulating the BSCB function remains unclear. The BSCB model in vitro was established via a coculture of primary rat brain microvascular endothelial cells (RBMECs) and spinal cord astrocytes on transwell system.

[Inhibitory effect of miR-429 on expressions of ZO-1, Occludin, and Claudin-5 proteins to improve the permeability of blood spinal cord barrier ].

Objective: To explore the feasibility and mechanism of inhibiting miR-429 to improve the permeability of the blood spinal cord barrier (BSCB) , and provide a new gene therapy target for enhancing the spinal cord microenvironment.

Methods: First, the immortalized human brain microvascular endothelial cell line (hCMEC/D3) was transfected with the anti-miR-429 antagonist (antagomiR-429) and its negative control (antagomiR-429-NC), respectively. The miR-429 expression of hCMEC/D3 cells was observed by fluorescence microscopy and real-time fluorescence quantitative PCR to verify the transfection efficiency of antagomiR-429.

MiR-429 regulates blood-spinal cord barrier permeability by targeting Krüppel-like factor 6.

The blood-spinal cord barrier (BSCB) is an effective, tightly-connected tissue that reduces secondary spinal cord injury (SCI) by decreasing blood cell infiltration, inflammation, and neuronal cell death during primary SCI. However, the methods and molecular mechanisms of BSCB openness remain elusive. In the present study, we found that microRNA429 (miR-429) plays a vital role in the opening of the blood-spinal cord.

Liaoning Score for Prediction of Esophageal Varices in Cirrhotic Patients Who Had Never Undergone Endoscopy: A Multicenter Cross-Sectional Study in Liaoning Province, China.

Background And Aims: Endoscopy is necessary for assessment of esophageal varices (EVs) in cirrhotic patients, but its use is limited because of the poor compliance of patients and shortage of public health resources at primary hospitals or rural areas, especially in less well developed countries. A multicenter cross-sectional study aimed to establish a novel non-invasive score for prediction of EVs in cirrhotic patients who had never undergone endoscopy.

Methods: Patients with liver cirrhosis regardless of acute upper gastrointestinal bleeding (AUGIB) who underwent the first-time upper gastrointestinal endoscopy at 11 hospitals in Liaoning Province, China were considered.

OAT1 and OAT3 also mediate the drug-drug interaction between piperacillin and tazobactam.

This study aimed to demonstrate that organic anion transporters (OATs) mediate the drug-drug interaction (DDI) between piperacillin and tazobactam. After co-administration with piperacillin in rats, the AUC of tazobactam in plasma was significantly increased, and t was prolonged with significant reduction in plasma clearance, renal clearance and cumulative urinary excretion. In rat and human kidney slices, probenecid, p-aminohippurate and benzylpenicillin inhibited the uptake of piperacillin and tazobactam.

Afatinib Decreases P-Glycoprotein Expression to Promote Adriamycin Toxicity of A549T Cells.

We investigated the reversal effect of afatinib (AFT) on activity of adriamycin (ADR) in A549T cells and clarified the related molecular mechanisms. A549T cells overexpressing P-glycoprotein (P-gp) were resistant to anticancer drug ADR. AFT significantly increased the antitumor activity of ADR in A549T cells.
