The coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), evolved into a global pandemic. As ACE2 on the surface of alveolar cells of the lung epithelium is one of the potential target receptors for SARS-CoV-2, the respiratory symptoms are the most common presentation of COVID-19. The aim of our study was to investigate the morphological findings in lung tissue after being infected by SARS-CoV-2 and compare histopathologic changes in patients with COVID-19 infection history who died to those who survived. ⋯ As the COVID-19 pandemic continues, new complications following SARS-CoV-2 infection are identified. Newly observed entity in patients with COVID-19 infection history who survived is pulmonary pneumo-hematocele. The appearance of these lesion has become increasingly frequent.

Case Reports
Biventricular repair of double-outlet left ventricle by handmade trileaflet-valved conduit: A case report.
Double-outlet left ventricle (DOLV) is a rare congenital cardiac malformation in which both great arteries arise entirely or predominantly from the left ventricle. An extracardiac conduit is the first surgical option for repairing DOLV, specifically because its placement of the extracardiac conduit can be customized to accommodate all possible anatomical variations. The bovine jugular veins and homograft valves are often used as conduits. There have been no reports on the use of handmade trileaflet-valved conduits for correcting DORV. ⋯ Correction of the left ventricular double outlet with a handmade trileaflet-valved conduit has been shown to have excellent performance, and long-term outcomes should be followed over time.

To explore the mechanism of Epimedii Folium (HF) and Notoginseng Radix (NR) intervention in vascular dementia (VD). This study used the Traditional Chinese Medicine Systems Pharmacology (TCMSP) database to collect the active ingredients and potential drug targets of HF and NR, the Uniprot database to convert drug target names into gene names, GeneCards, Drugbank, Therapeutic Target Database, and Online Mendelian Inheritance in Man database to collect the potential disease targets of VD, and then combined them with the drug targets to construct the HF-NR-VD protein-protein interaction (PPI) network by Search Tool for the Retrieval of Interacting (STRING). Cytoscape (version 3.7.1) was used to perform cluster analysis of the PPI network. ⋯ KEGG pathway enrichment analysis revealed that TNF and PI3K/Akt signaling pathways may occupy the core status in the anti-VD system. Molecular docking results confirmed that the core targets of VD had a high affinity for the main compounds of the HF-NR couplet medicine. We demonstrated the multi-component, multi-target, and multi-pathway characteristics of HF-NR couplet medicine for the treatment of VD and provided a foundation for further clinical application and experimental research.

Observational Study
Risk factors for in-stent restenosis after coronary stent implantation in patients with coronary artery disease: A retrospective observational study.
To explore the risk factors for in-stent restenosis (ISR) after stent implantation in patients with coronary heart disease (CHD) using logistic regression analysis. From February 2020 to February 2022, 350 patients with CHD after percutaneous coronary intervention (PCI) were divided into a stent stenosis group and a stent nonstenosis group based on coronary angiography results performed 2 years after PCI. Univariate and multivariate logistic regressions were used to analyze the factors related to ISR after coronary stent implantation in patients with CHD. ⋯ There were no significant differences in the blood lipid level, left ventricular ejection fraction, clopidogrel/ticagrelor or beta-blocker withdrawal, location of culprit vessels, and thrombotic lesions between the 2 groups (P > .05). Multivariate logistic regression analysis showed that family history of CHD, history of type 2 diabetes, hypertension, smoking, and drinking, aspirin withdrawal, use of conventional doses of statins, calcified lesions, ≥ 3 implanted stents, stent length ≥ 30 mm, stent diameter < 3 mm, and tandem stenting were risk factors for ISR within 2 years after PCI. A family history of CHD, history of type 2 diabetes, hypertension, smoking, and drinking, discontinuation of aspirin, use of conventional dose statins, calcified lesions, ≥ 3 stent implantations, stent length ≥ 30 mm, stent diameter < 3 mm, and tandem stenting are risk factors for ISR within 2 years after PCI in patients with CHD.

Randomized Controlled Trial Multicenter Study
Biosimilar erythropoietin in anemia treatment (BEAT)-Efficacy and safety of a 1:1 dose conversion from EPREX® to EPIAO® in patients with end-stage renal disease on hemodialysis: A prospective, randomized, double blind, parallel group study.
EPREX®/ERYPO®/PROCRIT® (epoetin alfa, Janssen-Cilag GmbH) was the first available recombinant human erythropoietin (rHuEPO) and was universally reference product as per the recommendation provided by European Medicines Agency. EPIAO® is a biosimilar formulation of EPREX®, and making it a 1:1 dose conversion from EPREX® according to recommendation of European Medicines Agency. This study evaluated the clinical efficacy and safety of EPIAO® in subjects with end-stage renal disease receiving hemodialysis after intravenous administration. ⋯ EPIAO® demonstrated promising effectiveness and manageable safety in patients with end-stage renal disease on hemodialysis.
