Chemoradiotherapy for recurrent CBTs case report.

Background: Carotid body tumors (CBTs) are rare paragangliomas with an incidence of 1-2 per 100,000 individuals. While surgical resection remains the standard treatment, postoperative recurrence poses a clinical challenge.

Case Presentation: We describe a 49-year-old female with recurrent CBT involving the jugular foramen, managed with IGRT (60 Gy/30 fractions) and 4 cycles of CVD chemotherapy.

IGF2BP2 regulates gastric cancer radiotherapy resistance through HIF1α-mediated glycolysis.

This study reveals the core mechanism by which insulin-like growth factor 2 mRNA-binding protein 2 (IGF2BP2) drives tumor progression and radiotherapy resistance in gastric cancer (GC) through mA-dependent regulation of hypoxia-inducible factor 1α (HIF1α). Clinical analyses show that IGF2BP2 is significantly overexpressed in gastric cancer tissues, and its expression level is closely associated with tumor size and poor patient prognosis. Functional studies demonstrate that elevated expression of IGF2BP2 accelerates the transition of gastric cancer cells from the G1 phase to the G2/M phase of the cell cycle and markedly enhances cell proliferation and migration through anti-apoptotic effects.

Multiple primary cancers with gastrointestinal malignant tumors as the first manifestation: Three case reports and review of literature.

Background: The incidence of malignant gastrointestinal (GI) tumors is increasing, and advancements in medical care have significantly improved patient survival rates. As a result, the number of cases involving multiple primary cancers (MPC) has also increased. The rarity of MPC and the absence of sensitive and specific diagnostic markers often lead to missed or incorrect diagnoses.

Lumbosacral Paravertebral Tophaceous Gout on an Adolescent Mimicking Malignant Neoplasm in 18 F-FDG PET/CT.

Contrast-enhanced MRI was performed on a 17-year-old adolescent boy with chronic lumbar and lower-limb pain, which had worsened over the past 3 days. It revealed a suspicious malignant mass adjacent to right appendage of L5-S1 vertebrae, with mixed signals and heterogeneous and obvious enhancement. 18 F-FDG PET/CT was subsequently performed for staging.

Morphological specificity analysis of an image-based 3D model of airway filling in a difficult airway.

Background: The purpose of this study was to analyze position-specific morphological changes of the upper airway and to further assess the impact of these changes in difficult airway during intubation.

Methods: This observational comparative study included two groups (n = 20 patients/group): Group A had normal airway and Group B had difficult airway. Data obtained from two-dimensional magnetic resonance imaging were imported to Mimics V20.

Seven new freshwater species of from southern China (Crustacea, Amphipoda, Gammaridae).

Seven new species of the genus are described and illustrated from southern China. The new species Hou & Li, , Hou & Li, , Hou & Li, and Hou & Li, are characterized by inner ramus of uropod III half the length of outer ramus. Hou & Li, is characterized by inner ramus of uropod III 0.

A new terrestrial talitrid genus, , with two new species from Myanmar (Crustacea, Amphipoda, Talitridae).

Hou, with two new species is described from terrestrial habitats in Myanmar. This new genus is characterised by 4-dentate lacinia on left mandible, simple gnathopod I in both sexes, weakly chelate gnathopod II in male, simplidactylate pereopods and complex and lobed gills. Hou, closely resembles Hou, in gnathopod II merus and carpus protuberant on posterior margin; however, the former is distinguished from the latter by palp of maxilla I with two articles, coxal gills convoluted, and telson with nicks on surface.

Two new species and a new name (Crustacea: Amphipoda: Gammaridae) from Northwest China.

Two new species of the genus Gammarus are described and illustrated from Northwest China. A new species name Gammarus tianshan nom. nov.

Description of a new species of Victoriopisa Karaman & Barnard, 1979 (Crustacea: Amphipoda: Eriopisidae) from China, with a key to the genus Victoriopisa.

Victoriopisa multiartus sp. nov. is described from mangrove in Qi'ao Island, China.
