Combined hepatocellular-cholangiocarcinoma (cHCC-CCA), an extremely rare and underinvestigated subtype of primary liver cancer in children, generally has a poor prognosis and greater aggressiveness. Histological diagnosis of cHCC-CCA is difficult because of its diverse components, including hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA). cHCC-CCA shares some genetic alterations with HCC and CCA.

Background: BCR::ABL1-like or Philadelphia chromosome-like (Ph-like) acute lymphoblastic leukemia (ALL) was first reported in 2009. Ph-like ALL is characterized by gene signature similar to Philadelphia chromosome ALL, but without BCR::ABL1 fusions. Molecularly, Ph-like ALL is divided into seven categories, with CRLF2 and ABL-class rearrangements being the two most common subtypes, exhibiting alterations in distinct downstream signaling cascades.

Article Synopsis
  • * A retrospective study identified a case of Hu-PNS in a child, where anti-Hu antibody was detected, leading to the discovery of a ganglioneuroblastoma after imaging and pathology.
  • * The child received intravenous immunoglobulin and surgical treatment, resulting in improved neurological symptoms and no signs of disease progression, highlighting the importance of early detection for better outcomes.

Article Synopsis
  • Desmoplastic small round cell tumor (DSRCT) is a highly aggressive cancer with a low 5-year survival rate (15%-30%), typically treated with chemotherapy, radiation, and surgery, but few effective options are available.
  • This study highlights three pediatric DSRCT cases successfully treated with anlotinib, a multitarget receptor tyrosine kinase inhibitor, in combination with chemotherapy, leading to reduced tumor size and improved symptoms.
  • While one patient experienced complications and passed away post-surgery, the report suggests that anlotinib could be a viable treatment option for children with DSRCT, with manageable side effects like fatigue and hypertension.

Article Synopsis
  • Extranodal NK/T-cell lymphoma (ENKTL) in children lacks a standardized treatment, but a promising "sandwich" regimen combining chemotherapy (SMILE) and radiotherapy has been applied.
  • In a study with five patients (ages 9.8 to 14), four had stage II nasal disease and one had stage IV extra nasal disease, with all patients showing good responses after just two cycles of treatment.
  • Despite a minor case of severe side effects, overall results indicate that the regimen is well-tolerated, leading to high response rates and no treatment-related deaths, although further research with larger groups is needed for confirmation.

Mucormycosis caused by is an emerging and uncommon opportunistic infection in patients with hematological malignancies, with high mortality rates. Herein, we first report a case of pulmonary mucormycosis with in a 3-year-old girl recently diagnosed with B-cell acute lymphoblastic leukemia. The diagnosis was made using computerized tomography of the lung, metagenomic next-generation sequencing (mNGS) of blood and sputum specimens, and microscopic examination to detect the development of on the surgical specimen.

Telomere biology disorders (TBDs) induced by mutations manifest clinically with a spectrum of phenotypes, from silent carriers to a set of overlapping conditions. A rare frameshift mutation (c.591delG) encoding a truncated mutant TIN2 protein (p.

Objective: To analyze the mechanism of LINC00461 regulating the recurrence of diffuse large B cell lymphoma (DLBCL) through microRNA (miR)-411-5p/BCL2 interacting protein 3 (BNIP3) pathway.

Methods: DLBCL samples in TCGA and GSE12453 were used for differential analysis to find long noncoding RNA (lncRNA) related to DLBCL recurrence. The 4 DLBCL data with the highest and lowest expression levels of LINC00461 in the TCGA database were selected for GSEA enrichment analysis.

Article Synopsis
  • Relapse in children with acute lymphoblastic leukemia (ALL) commonly occurs within 3 years of remission, with the central nervous system (CNS) being a frequent site of extramedullary relapse.
  • Symptoms of CNS relapse can be subtle, often presenting as asymptomatic, but some patients may experience headaches and vomiting.
  • This study highlights three rare cases where obesity was the first symptom of CNS relapse in children with B-ALL, suggesting clinicians should be vigilant in monitoring for relapse even when typical symptoms are absent.

Rationale: Clitoris swelling as the initial clinical presentation of acute lymphoblastic leukemia (ALL) is extremely rare. These patients may be misdiagnosed with acute myeloid leukemia or solid tumor, and the main treatment can also be delayed.

Autophagy and the ubiquitin proteasome system (UPS) are two major protein degradation pathways involved in brain ischemia. Autophagy can compensate for UPS impairment‑induced cellular dysfunction. HECT, UBA and WWE domain containing E3 ubiquitin protein ligase 1 (Huwe1), an E3 ubiquitin ligase, serves critical roles in nervous system plasticity, regeneration and disease.

HECT, UBA and WWE domain-containing 1 (Huwe1), an E3 ubiquitin ligase involved in the ubiquitin-proteasome system, is widely expressed in brain tissue. Huwe1 is involved in the turnover of numerous substrates, including p53, Mcl-1, Cdc6 and N-myc, thereby playing a critical role in apoptosis and neurogenesis. However, the role of Huwe1 in brain ischemia and reperfusion injury remains unclear.

Placental hypoxia serves a role in the early stages of normal pregnancy and is involved in the pathophysiology of preeclampsia. Previously, it was suggested that p57kinase inhibitory protein (KIP)2 regulates the cell cycle during embryogenesis and apoptosis. Recent evidence has indicated that p57KIP2 is increased in preeclamptic placentas and absence of p57KIP2 induces preeclampsia‑type symptoms in rats.

Background: Growth arrest and DNA-damage inducible protein 45 beta (Gadd45b) is serving as a neuronal activity sensor. Brain ischemia induces the expression of Gadd45b, which stimulates recovery after stroke and may play a protective role in cerebral ischemia. However, little is known of the molecular mechanisms of how Gadd45b expression regulated and the down-stream targets in brain ischemia.

Article Synopsis
  • Apoptosis is crucial in the development of ischemic strokes, and studying it in models of brain injury shows promising insights.
  • The study investigates the role of the Gadd45b protein in brain ischemia using adult male rats, where its expression was reduced using RNA interference.
  • The results revealed that reducing Gadd45b led to larger brain injury areas, worse neurological outcomes, and increased neuronal apoptosis, suggesting Gadd45b helps protect against cell death in ischemic conditions.

Stroke causes devastating and irreversible losses of neurological function with subsequent slow and incomplete recovery of lost brain functions, because of the brain's limited capacity for brain plasticity. Growth arrest and DNA-damage-inducible protein 45 beta (Gadd45b) has recently been demonstrated as a candidate plasticity-related gene, making it an excellent candidate molecule that has therapeutic potential. Here, we examine whether in vivo blockage of Gadd45b affects axonal plasticity and subsequent functional recovery after focal brain infarction.

Article Synopsis
  • The study aimed to explore the link between the SNP rs12740374 and acute ischemic stroke in a Chinese Han population, involving 778 stroke patients and 602 controls.
  • Researchers used genotyping techniques to compare genetic variations between the two groups and also looked at the connection of rs12740374 with low-density lipoprotein cholesterol (LDL-C) levels.
  • The findings indicated that while all genotypes of rs12740374 were present in both groups, there was no significant association between this SNP and ischemic stroke or LDL-C levels after accounting for other risk factors.
