Dynamic Nomogram for Predicting the Risk of Perioperative Neurocognitive Disorders in Adults.

Background: Simple and rapid tools for screening high-risk patients for perioperative neurocognitive disorders (PNDs) are urgently needed to improve patient outcomes. We developed an online tool with machine-learning algorithms using routine variables based on multicenter data.

Methods: The entire dataset was composed of 49,768 surgical patients from 3 representative academic hospitals in China.

A new, feasible, and convenient method based on semantic segmentation and deep learning for hemoglobin monitoring.

Objective: Non-invasive methods for hemoglobin (Hb) monitoring can provide additional and relatively precise information between invasive measurements of Hb to help doctors' decision-making. We aimed to develop a new method for Hb monitoring based on mask R-CNN and MobileNetV3 with eye images as input.

Methods: Surgical patients from our center were enrolled.

Serum Soluble Vascular Endothelial Growth Factor Receptor 1 as a Potential Biomarker of Hepatopulmonary Syndrome.

Background And Aims: The results of basic research implicate the vascular endothelial growth factor (VEGF) family as a potential target of hepatopulmonary syndrome (HPS). However, the negative results of anti-angiogenetic therapy in clinical studies have highlighted the need for markers for HPS. Therefore, we aimed to determine whether VEGF family members and their receptors can be potential biomarkers for HPS through clinical and experimental studies.

Xanthohumol chalcone acts as a powerful inhibitor of carcinogenesis in drug-resistant human colon carcinoma and these effects are mediated via G2/M phase cell cycle arrest, activation of apoptotic pathways, caspase activation and targeting Ras /MEK/ERK pathway.

Purpose: Xanthohumol is a prenylated flavonoid of plant origin and has been reported to exhibit a spectrum of pharmacological properties including anticancer effects. However, the anticancer properties of Xanthohumol have not been thoroughly evaluated against drug-resistant colon cancer cells. This study was undertaken to evaluate the anticancer effects of Xanthohumol against the human colon cancer cell line HT-29 and normal CDD-18Co cell line.

Withaferin-A Inhibits Growth of Drug-Resistant Breast Carcinoma by Inducing Apoptosis and Autophagy, Endogenous Reactive Oxygen Species (ROS) Production, and Inhibition of Cell Migration and Nuclear Factor kappa B (Nf-κB)/Mammalian Target of Rapamycin (m-TOR) Signalling Pathway.

BACKGROUND The main purpose of this study was to assess in vitro and in vivo the anticancer effect of withaferin-A in human breast carcinoma cells (MDA-MB-231), and to assess its effects on autophagy, cell apoptosis, ROS production, cell migration and invasion, and Nf-kappaB/m-TOR signalling pathway. MATERIAL AND METHODS Proliferation of MDA-MB-231 cells at various doses of the drug was studied by CCK8 cell viability assay. Effects on cell apoptosis were studied by fluorescence microscopy in combination with flow cytometry and Western blot analysis.

Inhibitory effects of petasin on human colon carcinoma cells mediated by inactivation of Akt/mTOR pathway.

Background: Colorectal cancer is the third most common cancer worldwide and still lack of effective therapy so far. Petasin, a natural product found in plants of the genus Petasites, has been reported to possess anticancer activity. The present study aimed to investigate the anticolon cancer activity of petasin both in vitro and in vivo.

Effect of ulinastatin donor-pretreatment on liver graft during cold preservation in rats.

Background: Donor-pretreatment with ulinastatin may influence the liver graft during cold preservation. The aim of this research was to determine whether pretreatment of donor liver with Ulinastatin can attenuate cold preservation injury, and to explore the mechanism by which Ulinastatin affects the donor liver graft.

Methods: One hundred and forty-four Wistar rats were divided into the Ulinastatin treatment group (T group) pretreated with Ulinastatin 50 000 U/kg and control group (C group) treated with 0.

Effect of blocking IGF-I receptor on growth of human hepatocellular carcinoma cells.

Aim: To study the expression level and localization of insulin-like growth factor -I receptor (IGF-IR) in HepG2 cells and Chang liver cells, and to observe the effect of anti-IGF-IR monoclonal antibody (alphaIR3) on the growth of HepG2 cells.

Methods: The expression of IGF-IR in HepG2 cells and Chang liver cells was detected by immunohistochemistry. The influences of alphaIR3 on proliferation and apoptosis were examined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and electron microscopy, respectively.
