Simple Evaluation of Clinical Situation and Subtypes of Pediatric Hemophagocytic Lymphohistiocytosis by Cytokine Patterns.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rapidly fatal disease caused by immune dysregulation. Early initiation of treatment is imperative for saving lives. However, a laboratory approach that could be used to quickly evaluate the HLH subtype and clinical situation is lacking.

Most Adult Intussusceptions are Caused by Tumors: A Single-Centre Analysis.

Background: Adult intussusception is less common than paediatric intussusception. The aim of this study was to explore the clinical presentation, aetiology, diagnosis and treatment of adult intussusception.

Methods: Adults (>18 years) with intussusception treated by surgical or conservative measures were included from January 2005 to January 2018, and the manifestation, types, diagnosis and treatment of adult intussusception in our centre were reviewed.

Demethylation of the RB1 promoter concomitant with reactivation of TET2 and TET3 impairs gastric carcinogenesis in K19-Wnt1/C2mE transgenic mice.

Aberrant methylation of promoter CpG islands (CGIs) can inactivate the expression of many tumor suppressor genes and play an important role in the carcinogenesis of gastric cancer. The tumor suppressor gene RB1, which encodes a cell cycle regulator, is hypermethylated and downregulated in multiple kinds of cancer. Activation of RB1 expression through DNA demethylation is a potential strategy for the treatment of gastric cancer.

Risk factors of cage nonunion after anterior cervical discectomy and fusion.

The aim of our study was to explore risk factors of cage nonunion after anterior cervical discectomy and fusion (ACDF).295 patients underwent ACDF in our hospital between Jan. 2014 and Jan.

Reactivation of Atp4a concomitant with intragenic DNA demethylation for cancer inhibition in a gastric cancer model.

Accumulating evidence suggests that aberrant DNA methylation and gene silencing of tumor suppressors are pervasive in gastric malignancies, supporting reactivation of tumor suppressors through DNA demethylation as a potential therapeutic opportunity. Atp4a is an important tumor suppressor gene, encoding H, K-ATPase, and mediating gastric acid secretion in the stomach. Using transgenic gastric cancer model K19-Wnt1/C2mE (Gan) mice, by combining the transcriptome and MeDIP (methylated DNA immunoprecipitation) sequencing, together with qRT-PCR, we showed that Atp4a was expressed at low levels in tumor tissues and multiple GC cells, while both 5-aza-CdR and 18β-glycyrrhetinic acid (GRA) pharmacological treatment triggered Atp4a activation with downregulation of DNMT1.

Preoperative Plasma Fibrinogen and Serum Albumin Score Is an Independent Prognostic Factor for Resectable Stage II-III Gastric Cancer.

Background: Radical gastrectomy with D2 lymphadenectomy is recognized as the standard treatment for resectable advanced gastric cancer. Preoperative fibrinogen and albumin measurements may bring clinical benefits in terms of providing advanced notice of a poor prognosis or recurrence in patients undergoing radical resection. The aim of this study was to identify markers that are predictive of a poor prognosis prior to surgery.

Efficacy and radiographic analysis of oblique lumbar interbody fusion for degenerative lumbar spondylolisthesis.

Background: To compare the clinical efficacy and radiographic analysis of oblique lumbar interbody fusion (OLIF) and traditional posterior lumbar interbody fusion (PLIF) in treating degenerative lumbar spondylolisthesis (DLS).

Methods: Grade I DLS patients admitted to the Third Hospital of Hebei Medical University were retrospectively reviewed. In sum, 78 patients that underwent OLIF (n = 31) and PLIF (n = 47) treatment of DLS were recruited.

Glomus tumor of the stomach: A case report.

Rationale: Glomus tumors (GTs) are a rare disorder originating from the glomus of the anastomoses of small arteries, usually occurring in the subungual region of the fingertips or toes and seldom occurring in the stomach. We unintentionally found a case of a gastric glomus tumor (GGT) without any upper abdominal discomfort. The diagnosis of this disease was mainly by immunohistochemistry.

18β-glycyrrhetinic acid inhibited mitochondrial energy metabolism and gastric carcinogenesis through methylation-regulated TLR2 signaling pathway.

The natural phenolic substance, 18β-glycyrrhetinic acid (GRA), has shown enormous potential in the chemoprevention of cancers with rich resources and biological safety, but the GRA-regulated genetic and epigenetic profiles are unclear. Deregulated mitochondrial cellular energetics supporting higher adenosine triphosphate provisions relative to the uncontrolled proliferation of cancer cells is a cancer hallmark. The Toll-like receptor 2 (TLR2) signaling pathway has emerged as a key molecular component in gastric cancer (GC) cell proliferation and epithelial homeostasis.

Study on the interaction between human serum albumin and a novel bioactive acridine derivative using optical spectroscopy.

The interaction of a novel bioactive agent N-{[N-(2-dimethylamino) ethyl] acridine-4-carboxamide}-α-alanine [N-(ACR-4-CA)-α-ALA] with human serum albumin (HSA) was investigated by fluorescence spectroscopy, UV-vis absorption and circular dichroism spectrophotometric techniques under simulative physiological conditions. The fluorescence quenching of HSA by addition of N-(ACR-4-CA)-α-ALA is due to static quenching and hydrogen bonding. Moreover, hydrophobic interactions play a role in the binding of N-(ACR-4-CA)-α-ALA to HSA as well.

Synthesis of a novel fluorescent probe based on acridine skeleton used for sensitive determination of DNA.

In this study, a novel fluorescent probe of acridine derivative N-((N-(2-dimethylamino)ethyl)acridine-4-carboxamide)-alpha-alanine (N-(ACR-4-CA)-alpha-ALA) was synthesized. The structure of the new compound was characterized by (1)H NMR, MS, elemental analysis, fluorescent and ultraviolet spectra. It was found that DNA had the ability to quench the fluorescence of N-(ACR-4-CA)-alpha-ALA, and the quenched intensity of fluorescence was proportional to the concentration of DNA.

Synthesis of a novel fluorescent probe and investigation on its interaction with nucleic acid and analytical application.

A novel fluorescent probe N-(N-(2-(4-morpholinyl)ethyl)-4-acridinecarboxamide)-alpha-alanine (N-(N-(ME)-4-ACA)-alpha-ALA) was synthesized. The structure was characterized by 1H NMR, MS, elemental analysis, fluorescent and ultraviolet spectra. This new compound exhibited high binding affinity to DNA, intense fluorescence and high water solubility.
