Clinical Efficacy of Detailed Intervention After Clopidogrel Treatment and Analysis of Angina Relief in Patients with CHD.

Objective: Coronary heart disease is incurable and prone to recurrence, and long-term dependence on medication and good nursing management to improve the prognosis. The effect of clopidogrel in the treatment of coronary heart disease is affected by many factors, so paying more attention to details in the process of patient care is conducive to creating more ideal recovery conditions for patients. The purpose of this study is to conduct detailed intervention for coronary heart disease (CHD) after clopidogrel treatment, and to analyze the clinical efficacy of this intervention mode on CHD patients and the relief of angina pectoris.

Circ-UBR4 regulates the proliferation, migration, inflammation, and apoptosis in ox-LDL-induced vascular smooth muscle cells via miR-515-5p/IGF2 axis.

The aim of our study is to disclose the role and underlying molecular mechanisms of circular RNA ubiquitin protein ligase E3 component -recognin 4 (circ-UBR4) in atherosclerosis (AS). Our data showed that circ-UBR4 expression was upregulated in AS patients and oxidized low-density lipoprotein (ox-LDL)-induced vascular smooth muscle cells (VSMCs) compared with healthy volunteer and untreated VSMCs. In addition, ox-LDL stimulated proliferation, migration, and inflammation but decreased apoptosis in VSMCs, which were overturned by the inhibition of circ-UBR4.

Brain network study of attentional cognitive impairment in children with bronchial asthma.

Bronchial asthma often causes cognitive impairment, especially attentional deficit, which has a serious impact on children's learning. This study aims to provide objective indicators for the evaluation of attention in asthma children. Thirty-one asthmatic and typically developing children (TDC) were tested by resting-state functional magnetic resonance imaging (rs-fMRI).

Long-Circulation and Brain Targeted Isoliquiritigenin Micelle Nanoparticles: Formation, Characterization, Tissue Distribution, Pharmacokinetics and Effects for Ischemic Stroke.

Purpose: We designed a novel isoliquiritigenin (ISL) loaded micelle prepared with DSPE-PEG as the drug carrier modified with the brain-targeting polypeptide angiopep-2 to improve the poor water solubility and low bioavailability of ISL for the treatment of acute ischemic stroke.

Methods: Thin film evaporation was used to synthesize the ISL micelles (ISL-M) modified with angiopep-2 as the brain targeted ligands. The morphology of the micelles was observed by the TEM.

Personalized warfarin treatment based on the PITX2 single nucleotide polymorphism rs6843082.

Objective: To explore the effect of PITX2 gene rs6843082 single nucleotide polymorphism on the efficacy and adverse reactions of warfarin in patients with atrial fibrillation and hypertension, and to provide a theoretical basis for individualized warfarin treatment.

Methods: Data on 97 patients with atrial fibrillation and hypertension treated in our hospital were collected from September, 2018 to December, 2019. PCR and SNP genotyping techniques were used to measure the genotype at the rs6843082 locus (pituitary homeobox 2, PITX2) using DNA from the peripheral blood cells of all patients.

Metformin promotes proliferation and suppresses apoptosis in Ox-LDL stimulated macrophages by regulating the miR-34a/Bcl2 axis.

: Metformin, an antidiabetic drug, has been reported to be involved in atherosclerosis (AS). In this study, the effects of metformin on oxidized low-density lipoprotein (Ox-LDL)-induced macrophage apoptosis were investigated, and the mechanisms involved in this process were examined. : qRT-qPCR analysis was performed to detect the expression of miR-34a in macrophage cells.

Transport of active flavonoids, based on cytotoxicity and lipophilicity: an evaluation using the blood-brain barrier cell and Caco-2 cell models.

This in vitro study aims to evaluate and compare transmembrane transport of eight cardio-cerebrovascular protection flavonoids including puerarin, rutin, hesperidin, quercetin, genistein, kaempferol, apigenin and isoliquiritigenin via the rat blood-brain barrier cell and Caco-2 cell monolayer models, based on the data of cytotoxicity and lipophilicity. The cytotoxicity of the flavonoids to rat brain microvessel endothelial cell was determined by the MTT assay. The apparent permeability coefficients (Papp) of the flavonoids were calculated from the unilateral transport assays in Transwell system with simultaneous determination using a high performance liquid chromatography.
