A Study on Overcoming Post-TACE Drug Resistance in HCC Based on Controllable Oxygen Release-Magnetic Hyperthermia Therapy.

Drug-eluting bead transcatheter arterial chemoembolization (D-TACE) is one of the first-line treatment for intermediate hepatocellular carcinoma (HCC). However, the dual hypoxia microenvironment, due to inherent tumor hypoxia and TACE-induced hypoxia, triggers drug resistance in HCC. To address this challenge, the study develops multicavitary microspheres capable of encapsulating oxygen and harnessing magnetic hyperthermia to enhance oxygen permeability.

Identification of MYCN non-amplified neuroblastoma subgroups points towards molecular signatures for precision prognosis and therapy stratification.

Background: Despite the extensive study of MYCN-amplified neuroblastomas, there is a significant unmet clinical need in MYCN non-amplified cases. In particular, the extent of heterogeneity within the MYCN non-amplified population is unknown.

Methods: A total of 1566 samples from 16 datasets were identified in Gene Expression Omnibus (GEO) and ArrayExpress.

The efficacy of extracted Tanshinone compounds for infantile hemangiomas of the skin: results from a pilot study.

Background: Infantile hemangiomas (IHs) on skin are conventionally treated with beta blockers, pulsed dye laser (PDL), or surgery, either invasive or limited to clinical conditions. Our preclinical studies suggested that Tanshinone, extracted from (Tanshin), had a beneficial effect on IHs. Thus, we conducted a pilot clinical study to evaluate the safety and efficacy of topical Tanshinone compounds on superficial IHs.

Histopathology of Ganglion Cells in the Proximal Resected Bowel Correlates With the Clinical Outcome in Hirschsprung Disease: A Pilot Study.

Introduction: Intraoperative leveling biopsy by identifying ganglion cells is crucial to determine surgical margin during surgery for Hirschsprung disease (HSCR). The anastomosis should be performed at least 5 cm proximal to the ganglionic segment to prevent transition zone pull-through. However, the length of the transition zone could be much longer than expected and the histological evaluation of the entire circumference of the proximal margin is recommended, which is time-consuming and not applicable for leveling biopsy.

P300 Interacted With N-Myc and Regulated Its Protein Stability via Altering Its Post-Translational Modifications in Neuroblastoma.

MYCN amplification is an independent risk factor for poor prognosis in neuroblastoma (NB), but its protein product cannot be directly targeted because of protein structure. Thus, this study aimed to explore novel ways to indirectly target N-Myc by regulating its post-translational modifications (PTMs) and therefore protein stability. N-Myc coimmunoprecipitation combined with HPLC-MS/MS identified 16 PTM residues and 114 potential N-Myc-interacting proteins.

KHSRP modulated cell proliferation and cell cycle via regulating PPP2CA and p27 expression in Wilms tumor.

Wilms tumor (WT) is the most common renal malignancy in children, and the survival rate of high-risk WT patients was still low despite multimodality therapy. KHSRP, an RNA-binding protein, has been proved to be relative to tumor progression in different kinds of malignancies, but the function of KHSRP in WT remained unclear. Here, our study aimed to explore and clarify the function of KHSRP in WT cells and its molecular mechanism.

PCLAF promotes neuroblastoma G1/S cell cycle progression via the E2F1/PTTG1 axis.

PCLAF (PCNA clamp-associated factor), also known as PAF15/ KIAA0101, is overexpressed in most human cancers and is a predominant regulator of tumor progression. However, its biological function in neuroblastoma remains unclear. PCLAF is extremely overexpressed in neuroblastoma and is associated with poor prognosis.

Recent Progress in Lymphangioma.

Lymphangioma is a common type of congenital vascular disease in children with a broad spectrum of clinical manifestations. The current classification of lymphangioma by International Society for the Study of Vascular Anomalies is largely based on the clinical manifestations and complications and is not sufficient for selection of therapeutic strategies and prognosis prediction. The clinical management and outcome of lymphangioma largely depend on the clinical classification and the location of the disease, ranging from spontaneous regression with no treatment to severe sequelae even with comprehensive treatment.

Successful thoracoscopic repair of traumatic diaphragmatic hernia in a child.

Traumatic diaphragmatic hernia is very rare in children, and the diagnosis is often missed or delayed. Herein, we reported a 2-year-old boy who had suffered with traumatic diaphragmatic hernia due to a car crash. The child was manifested as tachypnoea without any other severe symptoms.

Therefore, it is essential to fully understand the mechanical properties of steel-plastic compound geogrid-reinforced belts to utilize steel-plastic compound geogrids efficiently. In this study, tensile mechanical tests of steel wire, polyethylene geogrid belt, and steel-plastic compound geogrid-reinforced belt were conducted with respect to the tensile mechanical properties of steel-plastic compound geogrid-reinforced belts.

Exportin-T: A Novel Prognostic Predictor and Potential Therapeutic Target for Neuroblastoma.

Exportins as the key mediators of nucleocytoplasmic transport have been identified as the controllers of the passage of numerous types of crucial cancer-related proteins. Targeting exportins in cancer cells might represent an emerging strategy in cancer intervention with the potential to affect clinical outcomes. Here, we focused on the prognostic and therapeutic values of Exportin-T (XPOT) in neuroblastoma.

15,16-dihydrotanshinone I inhibits EOMA cells proliferation by interfering in posttranscriptional processing of hypoxia-inducible factor 1.

Infantile hemangioma (IH), which threatens the physical and mental health of patients, is the most common benign tumor in infants. Previously, we found that 15,16-dihydrotanshinone I (DHTS) was significantly more effective at inhibiting hemangioma proliferation in vitro and in vivo than the first-line treatment propranolol. To investigate the underlying mechanism of DHTS, we used EOMA cells as a model to study the effect of DHTS.

XPO1/CRM1 is a promising prognostic indicator for neuroblastoma and represented a therapeutic target by selective inhibitor verdinexor.

Background: High-risk neuroblastoma patients have a 5-year survival rate of less than 50%. It's an urgent need to identify new therapeutic targets and the appropriate drugs. Exportin-1 (XPO1), also known as chromosomal region maintenance 1, plays important roles in the progression of tumorigenesis.

Comparative Study of Thoracoscopic and Modified Small Incision Repair for Congenital Diaphragmatic Eventration in Children.

Thoracoscopic diaphragmatic plication has gained popularity in the treatment of congenital diaphragmatic eventration (CDE), but the therapeutic effect and prognosis have rarely been compared with nonendoscopic surgery. The medical records of 77 children who had received treatment for CDE in our institution from September 2006 to January 2019 were retrospectively analyzed. According to the repair approach, the children were divided into a thoracoscopic plication group and a modified small incision plication group.

Pre-mRNA processing factor 19 (Prp19) was previously reported to be involved in tumor progression. However, Prp19 expression and its functions remain elusive in neuroblastoma. Here, we aim to identify the functions and mechanisms of Prp19 in neuroblastoma.

Bufalin exerts antitumor effects in neuroblastoma via the induction of reactive oxygen species‑mediated apoptosis by targeting the electron transport chain.

The prognosis of high‑risk neuroblastoma remains poor. Clinical first‑line drugs for treating neuroblastoma have been developed over the previous half‑century; however, progress in the identification of new drugs with high efficiency is required. Bufalin, one of the major components of extracts obtained from the venom of the Chinese toad Bufo gargarizans, which is used to treat heart failure in Asian Pacific countries, has been reported to be a potential drug against multiple types of tumor; however, the detailed mechanisms underlying its antitumor activities remain unclear, largely due to lack of knowledge regarding its targets.

MYT1 attenuates neuroblastoma cell differentiation by interacting with the LSD1/CoREST complex.

Impaired neuronal differentiation is a feature of neuroblastoma tumorigenesis, and the differentiation grade of neuroblastoma tumors is associated with patient prognosis. Detailed understanding of the molecular mechanisms underlying neuroblastoma differentiation will facilitate the development of effective treatment strategies. Recent studies have shown that myelin transcription factor 1 (MYT1) promotes vertebrate neurogenesis by regulating gene expression.

Follow-Up Report of Laparoscopic Fundoplication in Different Types of Esophageal Hiatal Hernia in Children.

This study aimed to investigate and compare the efficacy, complications, and long-time outcomes after laparoscopic fundoplication between type I and type II-IV hernia patients.

The deubiquitinating enzyme UCHL1 is a favorable prognostic marker in neuroblastoma as it promotes neuronal differentiation.

Background: Neuroblastoma (NB) is the most common pediatric solid tumor that originates from neural crest-derived sympathoadrenal precursor cells that are committed to development of sympathetic nervous system. The well differentiated histological phenotype of NB tumor cells has been reportedly associated with favorable patient outcome. Retinoic acid (RA) can effectively induce NB cell differentiation, thereby being used in the clinic as a treatment agent for inducing the differentiation of high-risk NB.

Both serum and tissue Galectin-1 levels are associated with adverse clinical features in neuroblastoma.

Background: Neuroblastoma is one of the most common pediatric solid tumors. Although the 5-year overall survival rate has increased over the past few decades, high-risk patients still have a poor prognosis due to a lack of biomonitoring therapy. This study was performed to investigate the role of Galectin-1 in neuroblastoma biomonitoring therapy.
