Methods: First, differences in cisplatin resistance, PA2G4 gene expression, migration, and invasion in A2780 cells and A2780/DDP cells were analyzed by qRT-PCR, scratch assay, transwell, immunofluorescence, and western blotting.

Immunogenic cell death: A new strategy to enhancing cancer immunotherapy.

Immunogenic cell death (ICD) is a distinct type of stress-induced regulated cell death that can lead to adaptive immune responses and the establishment of immunological memory. ICD exhibits both similarities and differences when compared to apoptosis and other non-apoptotic forms of regulated cell death (RCD). The interplay between ICD-mediated immunosurveillance against cancer and the ability of cancer cells to evade ICD influences the host-tumor immunological interaction.

LncRNA H19 Promotes Angiogenesis in Mouse Pulmonary Artery Endothelial Cells by Regulating the HIF-1α/VEGF Signaling Pathway.

Persistent pulmonary hypertension of the newborn (PPHN) is a syndrome of acute respiratory failure characterized by systemic hypoxemia and elevated pulmonary arterial pressure, which leads to pathological changes in pulmonary vascular remodeling and endothelial cell function. Long non-coding RNA (lncRNA) H19 has been shown to be involved in the regulation of arterial endothelial cell function, but its regulatory role in PPHN is not fully understood. In the present study, mouse pulmonary artery endothelial cells (MPAECs) were cultured in a hypoxic conditions.

Online registry of neonatal necrotising enterocolitis in Shenzhen: protocol for a multicentre, prospective, open, observational cohort study.

Introduction: Necrotising enterocolitis (NEC) of the intestine of preterm infants leads to the risk of abdominal surgery, short bowel syndrome, neurodevelopmental disorders and death. Although the risks of NEC and its complications have been recognised in many countries, few countries have established NEC-specific registries to continuously monitor its aetiology and prognosis. In China, the understanding of risk factors and prognosis of NEC is incomplete, characterised by a lack of evidence from prospective and multicentre studies.

Design: Cross-sectional, observational, non-interventional study.

Isolated superior mesenteric artery dissection with concomitant vascular aberrancy: Extremely rare cases and clinical implications.

Objective: Vascular aberrancy of superior mesenteric artery (SMA) may contribute to the occurrence of SMA dissection. However, there is no direct evidence to support this hypothesis. Etiology, natural history, classification, and treatment options of ISMAD are still in controversial at some degree.

Immunomodulatory effect and molecular mechanism of deoxyribonucleic acid receptor toll-like receptor 9 signaling pathway on newborn babies with acute lung injury.

This work was to demonstrate the immunomodulatory effect of toll-like receptor 9 (TLR9) signaling on newborn babies with acute lung injury (ALI) and the mechanism of TLR9 in vivo, so as to provide experimental basis for clinical treatment of newborn babies with ALI. Firstly, the expression of TLR9 in peripheral blood mononuclear cell (PBMC) was compared among ALI and healthy newborn babies. Then, PBMCs of newborn babies with ALI were extracted and divided into three groups.

This study aimed to assess HRQoL of Tibetan and its changes over time, and explore the differences in HRQoL for residents at different altitudes.

Immune Remodeling during Aging and the Clinical Significance of Immunonutrition in Healthy Aging.

Aging is associated with changes in the immune system and the gut microbiota. Immunosenescence may lead to a low-grade, sterile chronic inflammation in a multifactorial and dynamic way, which plays a critical role in most age-related diseases. Age-related changes in the gut microbiota also shape the immune and inflammatory responses.

HLF promotes ovarian cancer progression and chemoresistance via regulating Hippo signaling pathway.

Hepatic leukemia factor (HLF) is aberrantly expressed in human malignancies. However, the role of HLF in the regulation of ovarian cancer (OC) remains unknown. Herein, we reported that HLF expression was upregulated in OC tissues and ovarian cancer stem cells (CSCs).

Distribution of potentially toxic elements in soils and sediments in Pearl River Delta, China: Natural versus anthropogenic source discrimination.

Although anthropogenic contamination has been regarded as the most important source of potentially toxic elements (PTEs) in soils of large river delta plains, the extent to which human activities affect PTEs in soils is worth exploring. This study used high density geochemical data to distinguish source patterns of PTEs in soils of the Pearl River Delta Economic Zone, a large industrialized and urbanized area in China. Enrichment factor, discriminant analysis, principal components analysis, cumulative distribution function, and positive matrix factorization were used to identify sources of PTEs in soils.

Dental Pulp Stem Cell-Derived Exosomes Regulate Anti-Inflammatory and Osteogenesis in Periodontal Ligament Stem Cells and Promote the Repair of Experimental Periodontitis in Rats.

Purpose: Dental pulp stem cell-derived exosomes (DPSC-EXO), which have biological characteristics similar to those of metrocytes, have been found to be closely associated with tissue regeneration. Periodontitis is an immune inflammation and tissue destructive disease caused by plaque, resulting in alveolar bone loss and periodontal epithelial destruction. It is not clear whether DPSC-EXO can be used as an effective therapy for periodontal regeneration.

Adrenomedullin induces cisplatin chemoresistance in ovarian cancer through reprogramming of glucose metabolism.

Background And Objectives: The metabolic network of cancer cells has been reprogrammed - relying more on aerobic glycolysis to gain energy, which is an important reason for drug resistance. Expression of adrenomedullin (ADM) in ovarian cancer tissues is related to resistance to platinum-based drugs. In view of this, we intended to investigate the correlation between ADM and glucose metabolism reprogramming of tumor cells to clarify the possible mechanism of ADM-induced ovarian cancer cisplatin resistance through glucose metabolism reprogramming.
