Inflammatory index is a promising biomarker for maintenance hemodialysis patients with cardiovascular disease.

Background And Objectives: Maintenance hemodialysis (MHD) patients are at a higher risk of cardiovascular disease (CVD), a common complication and leading cause of death. Persistent micro-inflammation is a unique feature of MHD. Given the established role of inflammation in the pathogenesis of atherosclerosis, this study aims to explore whether novel inflammatory markers (inflammation index) can serve as independent risk factors for CVD in MHD patients.

A phosphoglycerate mutase 1 allosteric inhibitor overcomes drug resistance to EGFR-targeted therapy via disrupting IL-6/JAK2/STAT3 signaling pathway in lung adenocarcinoma.

Resistance to epidermal growth factor receptor (EGFR) inhibitors, from the first-generation erlotinib to the third generation osimertinib, is a clinical challenge in the treatment of patients with EGFR-mutant lung adenocarcinoma. Our previous work found that a novel allosteric inhibitor of phosphoglycerate mutase 1 (PGAM1), HKB99, restrains erlotinib resistance in lung adenocarcinoma cells. However, the role of HKB99 in osimertinib resistance and its underlying molecular mechanism remains to be elucidated.

Targeting AKR1B1 inhibits glutathione de novo synthesis to overcome acquired resistance to EGFR-targeted therapy in lung cancer.

Acquired resistance represents a bottleneck to molecularly targeted therapies such as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) treatment in lung cancer. A deeper understanding of resistance mechanisms can provide insights into this phenomenon and help to develop additional therapeutic strategies to overcome or delay resistance. Here, we identified a pharmacologically targetable metabolic mechanism that drives resistance to EGFR TKIs in lung cancer cell lines and patient-derived xenograft mice.

NRF2-GPX4/SOD2 axis imparts resistance to EGFR-tyrosine kinase inhibitors in non-small-cell lung cancer cells.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have achieved satisfactory clinical effects in the therapy of non-small cell lung cancer (NSCLC), but acquired resistance limits their clinical application. NRF2 has been shown to enhance the resistance to apoptosis induced by radiotherapy and some chemotherapy. In this study, we investigated the role of NRF2 in resistance to EGFR-TKIs.

Development and validation of a rapid, robust and sensitive UPLC-QQQ-MS/MS method for simultaneous quantification of GSH metabolism in lung cancer cells.

Changes in cellular metabolism accompany tumor therapeutic resistance. Metabolite concentrations specifically reflect the cellular state. Glutathione (GSH) metabolism maintains the redox homeostasis while also confers therapeutic resistance to cancer cells.

Aldehyde dehydrogenase 1A1 confers erlotinib resistance via facilitating the reactive oxygen species-reactive carbonyl species metabolic pathway in lung adenocarcinomas.

Acquired resistance to epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) such as erlotinib is a major challenge to achieve an overall clinical benefit of the targeted therapy. Recently, aldehyde dehydrogenase 1 (ALDH1) induction has been found to render lung adenocarcinomas resistant to EGFR-TKIs, and targeting ALDH1A1 becomes a novel strategy to overcome resistance. However, the molecular mechanism underlying such effect remains poorly understood.

Purification and characterization of a novel ubiquitin-like antitumour protein with hemagglutinating and deoxyribonuclease activities from the edible mushroom Ramaria botrytis.

A novel ubiquitin-like antitumour protein (RBUP) was isolated from fruiting bodies of the edible mushroom Ramaria botrytis. The protein was isolated with a purification protocol involving ion exchange chromatography on DEAE-Sepharose fast flow and gel filtration on Sephadex G-75. SDS-PAGE, Native-PAGE and ultracentrifugation analysis disclosed that RBUP was a monomeric protein with a molecular weight of 18.

Multidisciplinary effort in treating children with hepatoblastoma in China.

The purpose of this study is to report the first nationwide protocol (Wuhan Protocol) developed by Chinese Children's Cancer Group and the results of multidisciplinary effort in treating hepatoblastoma. In this study, we reported the final analysis, which includes 153 hepatoblastoma patients in 13 hospitals from January 2006 to December 2013. The 6-year overall survival and event-free survival rates were 83.

Engineered measles virus Edmonston strain used as a novel oncolytic viral system against human neuroblastoma through a CD46 and nectin 4-independent pathway.

Neuroblastoma (NB) is the most common extracranial solid tumor in children. In this study, we investigated the potential antitumor capability of the engineered Edmonston strain of the carcinoembryonic antigen-expressing measles virus (MV-CEA) against human NB. The infection of a variety of NB cell lines, including SK-N-SH, SMS-KCNR, and primary NB cells, resulted in significant cytopathic effects.

Alveolar soft part sarcoma occurring on the abdominal wall of a 2-year-old child.

Alveolar soft part sarcoma (ASPS) is a rare soft tissue malignant neoplasm that affects young people. It can occur in any region of the body and at any stage of development. But ASPS on the abdominal wall is rarely reported.

Thoracoabdominal foregut duplication cyst with respiratory epithelium and alimentary epithelium.

Thoracoabdominal foregut duplication is a rare congenital abnormality. The authors report a case of thoracoabdominal foregut duplication cyst in a 13-year-old male patient. The pathologic report revealed that a thoracic mass with a pseudostratified, ciliated, columnar epithelial lining (respiratory tract epithelium), an abdominal mass with gastric mucosa (alimentary tract epithelium), and the cyst originated from the foregut.

Ileal duplication with extensive gastric heterotopia in a girl.

Background: Gastrointestinal duplications are rare congenital abnormalities known to occur at any level of the alimentary tract from the mouth to the anus. The cause of intestinal duplication has not been established. Several theories have been put forward to explain different types of duplications.

Thoracic rib solitary eosinophilic granuloma in a child.

Eosinophilic granuloma is characterized by single or multiple skeletal lesions occurring predominantly in children, adolescents, and young adults, it accounts for 70% of Langerhans cell histiocytosis. The common sites are the skull, mandible, ribs, spines, and long bones particularly the femur and the humerus. Thoracic rib involvement is rarely seen.

Presacral extrarenal Wilms tumor in a child.

Objectives: Wilms tumor (WT) is one of the most common solid tumors in children. It also is the most frequent tumor found in the kidneys. In 5% of cases, it affects both kidneys simultaneously.

Clinical images. Primary non-Hodgkin's lymphoma of the sigmoid colon in a child.

Primary non-Hodgkin's lymphomas of the gastrointestinal tract are rare in children, and few of these lymphomas are located in the sigmoid colon. The preoperative diagnosis rate is low. Complete resection is indicated if it can be done safely.

Castleman disease is a rare benign lymph node hyperplasia usually presenting as an asymptomatic mediastinal mass in children. It can present at any extrathoracic site where there is lymphoid tissue. The sites include retroperitoneum, mesentery, axilla, and pelvis.

[Blocking TrkB-BDNF signal pathway decreases the livability of neuroblastoma cells].

Objective: Brain-derived neurotrophic factor (BDNF) and its specific tryrosin kinase receptor-B (TrkB) are highly correlated to the chemoresistance of neuroblastoma (NB) cells and poor prognosis. This study observed the changes of the sensibility of NB cells to chemotherapy drug cisplatin (CDDP) before and after blockage of TrkB-BDNF signal pathway by specific tyrosin kinase inhibitor K252a.

Methods: Human NB cell line SH-SY5Y (SY5Y) was routinely cultured.

Objective: To establish stable techniques of comparative genomic hybridization (CGH) and apply them to elucidate the genetic characteristics of hepatoblastoma (HB), and to explore the characteristics and clinical significance of loss of heterozygosity (LOH) at 1p36 in HB.

Methods: CGH was employed to detect the genomic imbalance (DNA loss or amplification) in 20 cases of HB, and PCR-simple repeated sequence polymorphism was employed in 30 cases of HB to detect the loss of heterozygosity for 6 satellites at chromosome 1p36.

Results: There were different chromosome variations for each HB.
